Forging die design procedure and general requirements

forging die design procedure and general requirements:

forging die design is to achieve a certain deformation process. Therefore, in production, we should first determine the deformation process and die forging equipment according to the size, shape, technical requirements, production batch size and the specific situation of the workshop, and then design the forging die. The procedure of forging die design is as follows:

1. Analyze the shape of the finished product (study the forging process of the finished product)

2. Design forging drawing according to part drawing

3. determine the manufacturing method (several pieces of the first mock examination) and the type of equipment, and calculate the required tonnage

4. determine the die forging steps and design the die bore. The sequence is to design the final forging die bore first, and then design the pre forging die bore and blank making die bore

5. Design forging die body (or die assembly)

6. design trimming die and punching die

7. Set up a general WDW (5) 0 microcomputer controlled electronic universal, which can be based on the national standard, static bending strength, bending modulus of elasticity, surface bonding strength, bonding strength, screw grip force and other conventional experimental data. The experimental machine is the often used meter correction module (as needed)

8. President Li needs to purchase two universal experimental machines to determine the mold materials

the forging drawing is the basic technical document in production. According to it, the mold is designed, the size of the original blank is determined, and the forgings are accepted. The machining workshop also designs tools and fixtures according to the forging drawing

the work contents of forging drawing include:

(1) determine the position and shape of the parting surface

(2). Determine the allowance, tolerance and residual block

(3). Determine the die forging slope; If plastic is used to replace these materials

(4). Determine the fillet radius of forgings

(5). Determine the shape and size of punching connecting skin

(6) determine the shape and size of the web and reinforcement

the following requirements should be met when designing the forging die:

(1) ensure to obtain forgings that meet the dimensional accuracy requirements

(2). The forging die should have sufficient strength and high service life

(3). The forging die should be stable and reliable when working

(4). The forging die should meet the requirements of productivity when working

(5). Easy to operate

(6). Simple mold manufacturing

(7). Easy installation, adjustment and maintenance of forging die

(8). Try to save forging die materials on the premise of ensuring die strength

(9). The overall dimension of the forging die shall comply with the technical specifications of the equipment. (end)
