Embodiment Construction

[0029] One, basic technical scheme of the present invention:

[0030] Progressive die is an advanced and efficient stamping die in cold stamping dies. Stamping parts with complex shapes that require multiple processes such as punching and bending can be punched on a pair of progressive dies. Progressive die high-speed stamping can reduce labor, improve material utilization and production efficiency, and ensure product accuracy.

[0031] The CD box mounting bracket adopts the progressive die production method. First carry out stamping process analysis and layout, design the layout diagram, then design the mold structure, and finally manufacture and debug the mold.

[0032] 1. Stamping process plan and layout

[0033] For symmetrical parts, the left and right parts should be molded together as much as possible. This part is defined as a double-row punching part and adopts the form of an intermediate carrier, which can not only save material costs, improve material utilization...

Abstract

The invention discloses a multi-station progressive die for a CD case installation bracket. The multi-station progressive die comprises a lifting pin assembly, a retainer block assembly, a retainer plate, an upper template, a spring, a contour sleeve assembly, an upper base plate, a terrace die fixing plate, a guide pin, a checking plate, a bent terrace die, a pressing insert, a sliding guide post assembly, a large discharging plate, a small discharging plate, a cut-off terrace die, a lower die holder and a lower base plate. A left part and a right part are produced in a degenerating mode, so that the material utilization rate is improved and lateral force is avoided in forming and bending processes; and the requirements of high-speed precision production can be met, the production efficiency is improved, the production cost is reduced, the accuracy requirements of a product are ensured; and a progressive die form is adopted by the part which is formed by bending for multiple times, so that the benefits are obvious.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to a multi-station progressive mold for a CD case mounting bracket. Background technique [0002] The CD box mounting bracket is a common small part on the car. figure 1 Install the bracket for the left side of the CD case, and the right piece is completely symmetrical with it. The material is cold-rolled sheet DC01 with a thickness of 2.0mm and a tensile strength of 270-410MPa. The overall size is about 54mm×53mm×55mm, and its quality requirements are relatively high. The contour error on the A and B surfaces is less than 1mm, and the lower shadow part of the B surface is the welding surface; a hole on the A surface is another hole for The size of the long hole on surface B is 6±0.3×26±0.3mm. [0003] The processing of the CD box mounting bracket is processed by a stamping die. However, only ordinary stamping dies, such as single-process dies or composite dies, ...
