Combination Die for Stamping and Forming Lath-shaped Multi-curved Elastic Parts

Abstract

The invention discloses a one-stage combined press forming mold for lath-shaped multi-bend elastic parts, and relates to the technical field of press molds. The one-stage combined press forming mold disclosed by the invention comprises an upper platform of the mold, a lower platform of the mold, guide pillars and guide sleeves, and further comprises a material cutting mechanism, an extrusion forming mechanism and a discharging mechanism, wherein the material cutting mechanism can cut off material straps fed from the right side; the extrusion forming mechanism comprises a fixed forming concave mold, a main forming punch which can perform translational motion, a left extrusion forming punch and a right extrusion forming punch, mold shapes which are respectively matched with the left extrusion forming punch and the right extrusion forming punch are respectively arranged on the left lateral side and the right lateral side of the main forming punch, and the shape of a combined press forming cavity is consistent with the required shape of a lath-shaped multi-bend part. Through the adoption of the combined press forming mold disclosed by the invention, pressing, bending and forming can be completed in one stage, and rapid mold production of like products can be realized through simple replacement of parts and components, such as punches, so that raw materials are saved, and the cost and the investment of personnel and equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of punching dies, in particular to a combination die for one-time punching and forming of lath-shaped multi-bending elastic parts. Background technique [0002] In the past, there were several forming methods for relatively small metal stamping parts: single-process die, compound die and progressive die. Each forming method has its own advantages and disadvantages. 1. Single-process molds: such as punching molds, bending molds and composite molds, most of them need to go through multiple processes to complete the entire stamping part, so the accumulated error caused by the deviation caused by repeated positioning will directly affect the stamping Part shape, size and consistency. In addition, the use of single and multi-process molding molds requires many people and equipment, and the production efficiency and qualified rate of finished products are very low, resulting in waste of resources, and manual oper...

AI Technical Summary

Problems solved by technology

1. Single-process molds: such as punching molds, bending molds and composite molds, most of them need to go through multiple processes to complete the entire stamping part, so the accumulated error caused by the deviation caused by repeated positioning will directly affect the stamping Part shape, size and consistency

In addition, the use of single and multi-process molding molds requires many people and equipment, and the production efficiency and qualified rate of finished products are very low, resulting in waste of resources, and manual operation is also prone to work-related accidents. This type of mold is suitable for trial production of new products. Production of parts with small mass production and relatively low quality requirements

2. Multi-station progressive mold: Although the production of progressive mold can solve some problems in the single-process mold, the shape of the stamping part needs to be punched out, plus the carrier material connected with the material strip, the material utilization rate will drop significantly

Moreover, the maintenance of multi-station progressive molds requires high technical requirements for fitters. For progressive molds with complex mold structures, many parts, and high precision fit gaps, fitters with general technical levels cannot repair them.
