Embodiment 1

[0039] Embodiment 1, the mold of the present invention is described in detail by taking a flangeless cylindrical rotary drawing part as an example.

[0040] The material of this part is suitable for deep drawing with 08F cold-rolled thin steel plate. The thickness is 1.5mm. It can be seen from the drawings that the shape is simple and symmetrical. The diameter tolerance of the two circular openings is relatively large. There are no special requirements for tolerance and workpiece thickness. The part is designed as a hollow shell with a diameter of 60. The production process of the workpiece is determined as: blanking, punching, deep drawing, and flanging. The four processes are completed in one mold at a time.

[0041]A multi-process stamping composite mold, mainly composed of an upper mold part and a lower mold part, the upper mold part includes a limit post 2, a guide post 3, a guide sleeve 4, an upper die seat 5, a discharge plate 6, a spring 7. Cylindrical pin 8, pushing b...

Abstract

The invention provides a multi-procedure punching compound die, and belongs to the technical field of punching compound dies. Four procedures of blanking, punching, deep drawing and flanging can be finished synchronously, and continuous production is realized. The multi-procedure punching compound die comprises an upper die part and a lower die part. Mutual feeding is adopted, a blank guide pin is adopted by a blank guiding device, a blank stopping pin (33) is adopted for controlling feeding step pitches, spring unloading rigid striking parts are adopted by the die, a standard buffer mounted under a working bench of a punch machine is utilized to provide blank holding force. Guide manners of the upper die and the lower die are considered, the requirement of the size accuracy is general, large-scale production can be realized, correct punching and positioning of the upper die and the lower die are completed through matching a guide column with a guide sleeve, the production efficiency and quality of products are high, wear resistance, toughness, hardness and thermal stability of the die are good, matching accuracy and location of each part are good, assembling can be successful and no interference occurs, maintenance and disassembling are facilitated, a JC23-40F open-type punch machine can be selected to use for producing, and the multi-procedure punching compound die is particularly adaptable to large-scale production and automatic production.

Description

technical field [0001] The invention belongs to the technical field of stamping composite molds, and in particular relates to a multi-process stamping composite mold. Background technique [0002] Mold is an important process equipment used in the production of industrial products. It shapes raw materials in a certain way with its own special shape. In modern industrial production, molds are widely used due to their high processing efficiency, good interchangeability, saving raw materials, and low production costs. Forgings, stampings, die castings, and non-metallic parts are all formed by molds. Mold technology directly affects the development of the manufacturing industry, product upgrading capabilities and product competitiveness. The mold industry plays an extremely important role in the economic development of countries around the world. Mold technology has become one of the important symbols to measure a country's product manufacturing level. [0003] As a high-value...
