Problems solved by technology

[0004] (1) The utilization rate of materials is extremely low. The utilization of materials in this traditional process can be illustrated by Figure 1: except for the ring 3 which is the required product, the frame 1 and the small wafer 2 are waste materials; the cutting layer 4 and the fracture layer 5 There are burrs left, the appearance is bad, and it is necessary to increase the process of deburring;
[0005] (2) The sheet metal is expensive, the production efficiency is low, the punching die is fragile, and the processing cost is high; the labor intensity is high, and the safety and environmental protection are poor
[0006] (3) The precision of the gasket is poor, and the flatness, concentricity, and outer diameter cannot be guaranteed
[0008] (1) Low material utilization rate: manual feeding of bar steel (bar) has a large error in cutting length; cutting blanks according to equal weight requires frequent weighing, wasting man-hours, and low cutting efficiency; bar steel (bar) When cutting the blank, there is surplus material at the head and tail. When cutting in large quantities, a large amount of waste will be generated; if the punching process is placed before the forging process, the punching waste will thicken, and the accumulated waste will be large in mass production.
[0009] (2) Each process cannot be automatically connected, there are many and scattered processes, and it is easy to mix materials between processes; each process must be operated by a dedicated person; each process is prone to stagnation due to different production schedules, and a lot of handling time is increased. Low production efficiency and high processing cost
[0010] (3) Low product precision and unstable quality
[0011] (4) The labor intensity is high and the safety cannot be guaranteed

Embodiment Construction

[0040] Please refer to figure 2 , when the coiled wire used in the present invention is cut, shaped, preformed, formed, and punched, there are operations such as automatic feeding and automatic pinching. Before explaining the manufacturing process of the present invention, the automatic feeding and automatic pinching devices Wait for an explanation of the operation.

[0041] A. Automatic feeding:

[0042] The automatic feeding device of cold heading machine mainly includes: cam, feeding rocker, ratchet, pawl and feeding wheel and other components. The cam drives the feed rocker to make the ratchet actuate the ratchet to rotate an angle θ. When the ratchet rotates θ, the feeding wheel will synchronously rotate the angle θ to feed the material, then the feeding wheel will be divided into 2π / θ equal parts to feed the material. The effective working outer diameter of the wheel is D, and the feeding length each time is πD÷(2π / θ)=Dθ / 2.

[0043] Let the volume of the fifth blank ...

Abstract

The invention discloses the technology of forming thin shim with multistation cold heading machine, comprising the following steps: 1 blanking: feeding by automatic feeding unit, cutting stock; 2 shaping: forging stock; 3 preshaping: fixing station number according to product complexity and die forced condition, forging; 4 shaping: carrying out shim shaping and over bark shaping; 5 punching: punching the over bark of preformed pore to the required size. The technology is high speed, automatic and standardization method. The method not only improves the productivity and material utilization, but also lightens the intensity of labor, improves the product intensity, hardness, accuracy and general view quality, reduces the cost and possesses the good operation safety and environment protection.

Description

technical field [0001] The invention belongs to the field of metal forging processing, and relates to a process for forming a thin gasket by a multi-tasking cold heading machine with a disk element wire. Background technique [0002] Thin gaskets are fastening parts and are widely used in industries such as aviation, automobiles, military, medical equipment, electronic appliances, printing, textile machinery, tooling, fixtures, etc. The demand is huge and mass production is required. to be satisfied. [0003] Traditional craft (1): such as Figure 1A , 1B As shown, the sheet metal material is punched and blanked by using a punching machine. This process has the following defects: [0004] (1) The utilization rate of materials is extremely low. The utilization of materials in this traditional process can be illustrated by Figure 1: except for the ring 3 which is the required product, the frame 1 and the small wafer 2 are waste materials; the cutting layer 4 and the fracture...
