Description

A punching device for copper-containing low-carbon high-strength steel-based section steel

technical field

The utility model belongs to the field of punching, in particular to a punching device for copper-containing low-carbon and high-strength steel-based section steel.

Background technique

Stamping is an important part of the manufacturing process. It is required that the outer surface of the produced parts is not allowed to have defects such as wrinkles and dents, so as to improve its own rigidity and connect or fix interior parts and other parts. The stamping die has high production efficiency, easy operation, and is convenient for mechanization and automation. Stamping parts have better interchangeability. However, stamping dies are not suitable for the production of single-piece and small-batch parts, and under the traditional punching technology of copper-containing low-carbon and high-strength steel-based steel, due to the process of stamping, the clearance force and reaction force are not on the same line to generate torque . If the gap between the punch and the die is too large and the edge of the die has a reverse taper, or the contact area between the ejector and the workpiece is too small, it is easy to produce warpage deformation of the punched part. Unlevelling of the coil and anisotropy of the processed material lead to warpage of the stampings.

SUMMARY OF THE INVENTION

In order to overcome the deficiencies of the prior art, the purpose of this utility model is to provide a punching device for copper-containing low-carbon high-strength steel base section steel, which reduces the plane influence on the base section steel and reduces the occurrence of warpage deformation.

In order to achieve the above object, the utility model realizes through the following technical solutions:

A punching device for copper-containing low-carbon and high-strength steel-based section steel, comprising a pressing body, a transmission rod, a fixed body, a stabilizer rod, a sliding block, a shaping rod, a hydraulic cylinder, a push plate, and a stage; the middle of the pressing body is provided with The transmission rod is positioned at the center of the fixed body, and the transmission rod and the fixed body move up and down with the pressing body; the stabilizer bar is arranged in the pressing body on both sides of the transmission rod; It slides relative to the stabilizer rod. The shaping rod is located in the depressing body and can be rotated in the depressing body. There is a push plate on the stage below the transmission rod. The push plate is connected with the piston rod of the hydraulic cylinder. Under driving, it can reciprocate on the stage, and the four corners of the bottom of the pressing body are connected to the limit blocks.

The push plate has a straight plate-like structure or an annular structure.

The upper surface of the stage is annular.

Compared with the prior art, the beneficial effects of the present utility model are:

The punching device for copper-containing low-carbon and high-strength steel-based steel has a reasonable structure. By using this device, a qualified base steel can be punched out. It has little influence on the plane of the base steel, and the force is uniform, which will not affect the subsequent processing procedures. In the process of subsequent processing, deformation can be reduced, and trauma damage during operation can be avoided at the same time. The formed product falls on the stage, and is pushed to the outside of the device through the push plate, which does not affect the next processing.

Detailed ways

The present utility model will be described in detail below with reference to the accompanying drawings, but it should be pointed out that the implementation of the present utility model is not limited to the following embodiments.

See Figure 1, a punching device for copper-containing low-carbon high-strength steel-based section steel, including a pressing body 1, a transmission rod 2, a fixed body 3, a stabilizer rod 4, a sliding block 5, a shaping rod 6, a hydraulic cylinder, and a push plate 9. Object stage 7; the middle of the pressing body 1 is provided with a transmission rod 2, the transmission rod 2 is positioned at the center of the fixed body 3, and the transmission rod 2 and the fixed body 3 move up and down with the pressing body 1; the stabilizer bar 4 is arranged on the transmission rod 2 In the pressing body 1 on both sides, it is used to compress the plate during the stamping process; the sliding block 5 is arranged at the lower part of the stabilizer bar 4, and can slide relative to the stabilizer bar 4 in the pressing body 1, and the shaping rod 6 is located in the pressing body 1. , and can be rotated in the pressing body 1, a push plate 9 is provided on the stage 7 under the transmission rod 2, and the push plate 9 is connected with the piston rod 8 of the hydraulic cylinder, and the push plate 9 can be driven by the hydraulic cylinder. The object table 7 reciprocates, and the four corners of the bottom of the pressing body 1 are connected to the limit blocks 10 to prevent the upper half of the punching device from completely abutting on the object table during the punching process, so as to ensure the punching effect.

Among them, the push plate 9 is a straight plate structure or a circular structure, which can be designed according to the shape of the product, so as to prevent the product from being left on the stage 7 and affecting the next processing. The upper surface of the stage 7 is annular and matches the shape of the workpiece.
