Problems solved by technology

[0003] The reversing radar hole in the prior art uses the cylinder as the power source for punching. Because there is no guidance, the surface of the rear bumper of the car is often damaged. At the same time, the momentum of the cylinder is not enough, and the punched hole often has burrs and flanging, causing quality problems.
The above problems not only exist on vehicle bumpers, but may also exist on other products that require punching

Embodiment Construction

[0035] The core of the present invention is to provide a new type of punching mechanism, which can meet technological requirements and ensure product quality.

[0036] In order to make those skilled in the art better understand the solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Please refer to Figure 1-Figure 4 , The present invention provides a novel punching mechanism, comprising a gas-liquid booster cylinder 1, a mounting bracket 2, a profiling punch 16 and a guiding mechanism, wherein the mounting bracket 2 is used to fix the fixed end of the gas-liquid booster cylinder 1, The profiling punch 16 is arranged on the movable end of the gas-liquid booster cylinder 1, and the size is the same as that of the punching hole. The guide mechanism is used to provide punching guide for the movable end of the gas-liquid booster cylinder 1 .

Abstract

The invention provides a novel punching mechanism which comprises a gas-liquid pressure cylinder, a mounting support, a profiling convex mold and a guide mechanism. During punching, the profiling convex mold is driven by the gas-liquid pressure cylinder, the gas-liquid pressure cylinder presses a to-be-punched product to the profiling convex mold, then pressurization work is carried out, and therefore product punching is achieved. The gas-liquid pressure cylinder is used as a power source for punching, enough punching force is achieved, and under the guide action of the guide mechanism, precise locating can be achieved; and the product surfaces are prevented from being damaged, and therefore process requirements are met, and product quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of punching mechanisms, and is particularly suitable for a punching mechanism for reversing radar holes on automobile bumpers. Background technique [0002] For the punching hole of the reversing radar hole in the rear bumper of the car, the corresponding profiling concave and convex dies are designed according to the digital analog surface of the radar hole. The rear bumper is re-pressurized, so as to realize the punching of the reversing radar hole in the rear bumper of the car. [0003] The reversing radar hole in the prior art uses the cylinder as the power source to punch the hole. Because there is no guide, the surface of the rear bumper of the car is often damaged, and the impulse force of the cylinder is not enough. The punched hole often has burrs and flanging, causing quality problems. The above problems do not only exist in vehicle bumpers, but may also exist in other products that require punchi...
