Milling processing introduction

The process of machining the workpiece with a milling cutter on the milling machine is called milling processing, referred to as milling. Milling is one of the commonly used methods in metal cutting. During milling, the main motion of the milling cutter is rotated, and the feed motion of the workpiece is slow and straight.

Milling Characteristics

1) Milling cutter is a multi-tooth tool, in milling, milling cutter each tooth is not continuously cutting as a turning tool and drill, but intermittently cutting, the heat dissipation and cooling conditions of the tool are good, and the durability of the milling cutter is high, cutting speed can be improved;

2) Milling is often multi-tooth cutting and can use a larger cutting amount, compared with planing, milling has higher productivity, in batch and mass production, and milling has almost all replaced planning;

3) Due to the continuous cutting and cutting of the cutter teeth, the milling force is constantly changing, so it is easy to produce vibration in milling.

Safety operating regulations for milling machines

1. Before work, you must wear work clothes (military training uniforms), girls must wear a good work cap, braids must not be exposed, and protective glasses must be worn when performing knife operations.

2. Before work, carefully check whether the machine tool is abnormal, and fill lubricating oil and coolant in the specified parts.

3. Install the tool before processing, and then install and clip the workpiece. The clamping must be firm and reliable, and it is strictly forbidden to use the power of the machine tool to install the clamping tool rod and the pull rod.

4. The spindle speed change must be stopped. First, open the speed change operating handle, then select the speed, and finally reset the operating handle at the appropriate speed. When the reset speed is too fast, the impulse switch is difficult to act; Too slow to reach the start state is prone to damage the gear in action.

5. Before milling, the tool must leave the workpiece, and should check the direction of rotation of the milling cutter and the relative position of the workpiece is up-milling or up-milling, usually not using up-milling, but using up-milling. If it is necessary to use down-milling, the screw nut clearance of the workbench should be adjusted in advance to the appropriate degree before milling, otherwise it will cause a "cutting" or cutting phenomenon.

6. In processing, if the automatic feed is used, attention must be paid to the limit position of the stroke; Careful attention must be paid to the relative position between the milling cutter and the workpiece fixture. To prevent over-milling, milling fixture, and damage to the tool and fixture.

7. During processing, it is strictly prohibited to place excess workpieces, fixtures, tools, measuring tools, etc., on the workbench. Prevent collision, overlapping, and personal and equipment accidents.

8, the machine shall not leave the post or entrust others to watch during operation. No gossip, roughhouse, or jokes.

9. When two or more people jointly operate a machine tool, they must be strictly divided into divisions and operate in segments, and it is strictly prohibited to operate a machine tool at the same time.

10. Stop halfway to measure the workpiece, and do not brake the inertia of the milling cutter spindle by hand.

11. After the workpiece is removed after milling, it should be deburred in time to prevent pulling fingers or scratching other workpieces stacked.

12. In case of an accident, the power supply should be cut off immediately, the site should be protected, the accident analysis should be participated in, and the accident should bear the responsibility.

13. At the end of the work, the machine should be carefully cleaned, refueled, and the workbench should be moved near the column.

14. Clean the work site and pour the cuttings into the specified place.

Internal high-pressure forming technology is one of the lightweight forming technologies for auto parts, it uses liquid or gas as the transfer medium, through precise control of internal pressure, axial feeding, with mold cavity, and finally made of metal hollow billets constitute the whole complex variable cross-section components. The internal high-pressure forming equipment is suitable for the manufacture of complex hollow components with different cross-sections in the industries of aerospace, nuclear power, petrochemical, drinking water systems, pipeline systems, automobiles, bicycles, etc.

Classification of internal high-pressure forming hydraulic presses

1. Multi-station automatic presses:

There are multiple stations on a press with multiple forming dies installed, and the blank moves automatically to the next station in sequence. In one stroke of the press, each station performs each forming process simultaneously to manufacture the workpiece.

2. Rotary head presses:

Between the ram and the table, there is a rotating head where dozens of dies can be mounted, and the dies can be selected as needed. The blank is placed on the die and does not move anymore. After each stroke is completed, the rotary head rotates one position to finish the process. This press has high positioning accuracy and easy product adjustment. One machine is multi-purpose, mostly used for punching instrument base plates and panels. The rotary head press can be equipped with numerical control system, which can automatically complete complex punching work by selecting the die and plate forming parts according to the programming instruction.

3. Double-action deep drawing presses:

There are internal and external sliders for deep drawing of cup-shaped parts. Before deep drawing, the outer slider presses the outer edge of the plate first, and the inner slider drives the punch to pull the cup to prevent the outer edge of the plate from wrinkling. After the drawing is completed, the inner slider returns first and then releases the outer slider. The ratio of the nominal working force of the inner and outer slider is (1~1.7):1. 4.

4. Cold extruder:

Used to extrude metal parts in the cold and warm state, such as qiang shell, toothpaste tube, etc.. Cold extrusion presses are generally vertical, with good rigidity, high precision guidance, high working pressure, small working surface, long length, etc. Working stroke.

5. Hot-die forging presses:

Used for die forging production. Machine body stiffness, long guiding surface, strong ability to bear deflection load. In the past, the crank linkage mechanism was replaced by a double-slider type and wedge type to improve rigidity. The double-slider type structure is relatively simple and lightweight; the wedge-type structure has a large bearing area, but the transmission efficiency is low. When die forging, the slider is easy to be stuck near the lower stop (commonly known as a boring car), so there is a die release device. The machine is equipped with upper and lower ejector devices, which can realize multi-die forging and the forgings are highly accurate and suitable for mass production. The maximum specification is 160 MN.

Internal high-pressure forming hydraulic press is suitable for bending, forming, and flanging of center load parts. Equipped with a punching buffer, it can also be used for punching and drop processing. This product is preferred for a wide range of applications in the automotive, aviation, aerospace, and pipeline industries.

mechanical gears description and applications

 What are mechanical gears and their application markets

Gear transmission system is widely used in various industrial products and equipment, from design, manufacturing, and testing to application, forming their own technical field. In addition to metal cutting gears, in recent years, with the development and manufacture of high-tech products such as commercial machinery, 3C industry, intelligent machinery, plastic, powder metallurgy, and other non-cutting gears and non-metal cutting applications of precision pinion transmission mechanisms is increasing.

What is gear?

A gear or gear is a mechanical part with teeth on the rim that continuously meshes and transmits motion and power. Gears rely on the meshing of teeth to transmit torque. Gears are driven together with other toothed mechanical parts (gears, racks, worm gears). The transmission method is meshing transmission, which can realize the function of changing speed and torque, changing the direction of motion, and changing form of motion. The gear mechanism is widely used in industrial products because of its high transmission efficiency, accurate transmission ratio, and large power range.

What is the role of gears?

In the friction wheel transmission mechanism, if the positive pressure is not enough, the driving part will not have enough friction to drive the driven part, if the positive pressure is too large, it will occur slippage. Therefore, the edge of the wheel surface of the friction wheel according to a certain curve made of teeth, is used to replace the rolling cylindrical friction wheel. When the friction wheel move, this part is called a gear.

In industry, the main role of gears is to transmit power, and their applications are very wide. Gears are used in a wide range of applications, from the transmission mechanism of automobiles to mechanical watches.

Gears can be used to transmit large torques efficiently in a very small structure, and even very small amounts of power can be transmitted smoothly.

Low qty gears and high-precision gears can be made by CNC machining, laser cutting

Large qty can be made by die casting and machining.

Main application areas of the gear industry:

China's gear industry can be broadly divided into five categories: precision mechanical gears, automotive gears, reduction gears, precision pinion gears, and large gears.

1, precision machinery gears mainly supply machine tools, textile machinery, printing machinery, rubber and plastic machinery, fluid pumps, etc., the important key equipment is the gear grinding machine, precision often requires JIS 1 or 0 or even higher.

2. Automotive gears are mainly supplied to automobiles, locomotives, agricultural machinery, and scooters; the main processing equipment for hobbing machines, gear scraping machines, and gear shaving machines, belonging to the medium and large production type, high automation requirements, the application of higher production value and output value.

3. The main products of reducers are worm gear reducers and gear motor reducers, etc., which are widely used in various industries of machinery and equipment. In addition to supplying part of the domestic market, most of them are exported. In addition, the composition of cooperative factories, parts inventory, and assembly management are also a feature of this industry.

4. Fine gears are gears with a modulus of 1.0 or less. Most of these gears have only hardened and tempered materials with a low degree of hardening. However, because the number of teeth of the active gear shaft is small, especially the noise, the speed and quality of precision hobbing procedures are relatively high, and high-grade carbide hobbing cutters and high-speed hobbing machines are often used.

5. Large gear industry refers to the gear factory that can produce gears of more than one meter in diameter. In addition to hobbing or milling, after heat treatment and hardening, a further finishing process is required to meet the requirements of accuracy and life. These large gears are mostly used in petrochemical, mining research, cement, shipbuilding, sugar, steel, and other factory machinery.

The gear industry has a wide range of applications and has become a very important processing link in the machinery manufacturing industry. High-quality and high-precision gear components are installed in a variety of mechanical equipment, such as machine tools, industrial machinery, locomotives, power tools, etc..

In many new machinery and equipment, the use of gears is gradually decreasing, but in response to the new energy, energy saving, high precision, and high-speed industrial demand, the application of gear transmission mechanisms is still increasing. Especially in the case of unbalanced oil demand and steadily rising prices, the development of new energy sources and energy-saving methods will become increasingly urgent. Therefore, such as speed increasers for wind power generation and more fuel-efficient manual automatic transmissions are likely to become mainstream products in the future. In addition, high-precision products such as high-speed ratio gearboxes, metering gear pumps, high-load worm-gear reducers, and instrument-grade indexing discs are also worthy of industrial investment.
