Embodiment Construction

[0029] The inventive device such as figure 1 As shown, it includes a multi-station progressive die upper die 1, a stripper plate 2, a lower die 3, a guide pin 4, an insert 5 and a limit screw 6.

[0030] The device of the present invention assembles each part of the mold into a mold frame by means of assembly. The assembly of upper mold 1 and lower mold 3 fixed plate and stripper plate 2 plays a very important role in the assembly of multi-station progressive dies. The assembly accuracy of these three plates and the manufacturing accuracy of insert 5 determine the multi-position of the whole set. The quality of station progressive die. When assembling, select the datum surface and the datum hole as the datum, and the assembly datum coincides with the machining datum. The insert 5 should have an interference during assembly, and fasten it with pins or fastening screws after the embedding is completed.

[0031] Select the plane where the fixed plate of the die 3 is located as...

Abstract

The invention discloses a progressive die design of hoop parts. The progressive die design comprises a male die, a female die, a stripper plate and a strip stock layout of the whole progressive die. All the parts are combined together in an assembling mode and are fixed through pressing screws and positioning pins. The hoop parts have the characteristics of precision and thinness, have very high requirements on the material, the machining mode and the heat treatment process of workpieces, the error accumulation caused by multiple times of machining of a single die can be overcome by adopting the progressive die for machining, the workload of production workers is simplified, the production efficiency of the precise and fine hoop parts is improved, and large-scale batch production of the hoop parts is realized.

Description

technical field [0001] The invention relates to the technical field of stamping forming of parts, and specifically designs a progressive die for clamp parts based on a die process. Background technique [0002] The stamping forming process is a processing method of a workpiece with a certain size, shape and performance by applying an external force to the blank through a mold to cause plastic deformation or separation. This process can be used to manufacture and process workpieces with complex shapes and excellent performance, and has the characteristics of simple operation, high production efficiency and high material utilization. [0003] Multi-station progressive die is a stamping die for mass production of workpieces with complex structures. Through continuous processing of fixed-thickness sheet metal, the parts are decomposed into several stations with equal working distances for processing. Starting from the first station, the processing technology of each station is ...
