Barrel punch forming device

Abstract

The invention discloses a barrel punch forming device which comprises an upper die capable of extending into a barrel and a lower die located outside the barrel. The upper die and the lower die are matched with each other to clamp the barrel, a male die is movably arranged on the upper die, a groove for avoiding is formed in the lower die, and the male die can conduct punching on the surface of the barrel; the upper die is a cantilever and is fixedly arranged, and the upper die is kept fixed in the operation process; the lower die is driven by a clamping driver and can move to be close to or away from the upper die so as to clamp or loosen the barrel; the male die is driven by a punching driver to punch, and an avoiding space is provided by the groove in the lower die; the moving directionof the punching driver is perpendicular to the moving direction of the male die, so that the punching driver can be placed in a cavity in the barrel to punch the barrel; and the barrel punch formingdevice can punch a machined and formed barrel structure.

Description

Technical field [0001] The invention relates to the technical field of stamping equipment, and further relates to a cylinder stamping forming device. Background technique [0002] In recent years, high-speed and efficient production of stamping parts has become an important indicator for stamping companies to occupy the market. In automobile manufacturing, 60%-70% of metal parts need to be formed by plastic processing. Stamping is an important means to complete metal plastic forming. One of the most basic, traditional and important metal processing methods. [0003] With the rapid development of the automobile industry, the problems of environmental pollution and resource shortage are becoming more and more prominent. Saving resources and reducing pollution have become the two major problems to be solved in the automobile industry. Focusing on sustainable development, reducing automobile quality, reducing fuel consumption and reducing emissions pollution The task of automobile lig...

Problems solved by technology

[0003] With the rapid development of the automobile industry, the problems of environmental pollution and resource shortage have become increasingly prominent. Saving resources and reducing pollution have become two major issues to be solved in the automobile industry. Focusing on sustainable development, reduce the quality of automobiles, reduce fuel consumption and reduce emission pollution The task is particularly urgent, automobile lightweight technology is one of the important ways to solve these problems, research results show that every 10% reduction in automobile mass can reduce fuel consumption by 6-8%; although aluminum alloy has the advantage of light weight, in It is widely used in body structure, but the aluminum alloy is not good at stamping pressure, and it is easy to break during the stamping process. If the stamping force is reduced during the stamping process, it is easy to bond with the stamping.

[0004] The current stamping machinery and equipment are generally large-scale stamping machines. The stamping machine is fixed in the workshop. When working, the workpieces such as plates or wires are placed on the workbench. A huge stamping block on the upper part of the stamping machine moves through hydraulic pressure or free fall. Stamping the plate or wire, and bending the stamped plate and wire into various desired shapes, it is difficult to stamp the already bent cylindrical structure
