Anti-impact type precision punching mold supporting device for hot end gas inlet flange

Abstract

The invention provides an anti-impact type precision punching mold supporting device for hot end gas inlet flange, which comprises a workbench, an oil cylinder and a mold supporting element, wherein the mold supporting element comprises a mounting adjusting sleeve which is arranged at the upper end of the oil cylinder and provided with a plurality of anti-impact adjusting rods uniformly hinged tothe outer wall in the circumferential direction, a supporting rod, an adjustable top plate and a tightening supporting column. Impact force on the local area of the whole mold supporting device can bedispersed from the upper end, so that device damages caused by excessive local stress is avoided; the supporting area of the adjustable top plate can be adjusted according to the sizes of the precision punching molds, so that support of the precision punching molds of various sizes is met, universality is wide, the structure is simple, and operation is convenient; and meanwhile, a rotary disc canbe manually operated to rotate clockwise, and the work of adjusting the magnitude of pre-tightening force at the large hole position of the hot-end gas inlet flange is accomplished, so that deformation of the lower mold during punching is minimized, and the purposes of improving part precision and prolonging the service life of the mold are achieved.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to an impact-resistant fine-blanking die support device for a hot-end intake flange. Background technique [0002] In modern society, automobiles have become more and more popular vehicles, and various parts of automobiles, such as engine cylinder heads, cylinder blocks, exhaust pipes, intake flanges and other parts, have achieved mass and automated production. After the auto parts are produced, their size needs to be inspected to determine whether they are qualified. The intake flange is a common connecting part, and its shape is more complicated than the general flange, which is inconvenient to inspect. With the improvement of product performance With continuous improvement, the requirements for machining accuracy of the intake flange are also increasing. [0003] When the air intake flange is precision stamped, it is easy to cause mold deformation. When the mold pr...

AI Technical Summary

Problems solved by technology

[0003] When the air intake flange is precision stamped, it is easy to cause mold deformation. When the mold processes about 10,000 parts, the size error between the holes on the flange is relatively large, which cannot meet the requirements, resulting in unqualified product quality and processing Increased production costs and reduced production efficiency

The reason is that the thickness of the stainless steel thick plate flange is relatively large, and the hole in the middle is relatively large. When stamping, it is necessary to reserve a space for the ejector pin under the position of the large hole of the mold, so that the workbench is not supported under the bottom plate of the mold. Precision stamping The lower mold is constantly deformed during processing, and as a result, the dimensions between the holes on the flange do not meet the requirements

[0004] Therefore, a special device is needed to support the fine blanking die, and the existing fine blanking die support device has the following defects: 1) it cannot disperse the impact force received by the part of the support device, and the impact resistance is poor; 2) it cannot be based on Adjust the support area, poor versatility
