Description

A punching device with a pressing structure

technical field

The utility model relates to a mechanical device, in particular to a punching device with a pressing structure.

Background technique

In the process of auto parts processing, some through holes, mounting holes, pin holes and other hole parts need to be punched through the stamping process. The existing punching equipment has a relatively simple structure. Only the end face of the plate can be pressed, which results in that the edge of the hole may be damaged due to a huge impact when punching; and the current pressing device needs to be pressed manually, which is very inconvenient to use.

Utility model content

The purpose of the utility model is to provide a punching device with a pressing structure for the deficiencies in the prior art.

Technical solution: The technical solution adopted by the utility model to solve the problem is: a punching device with a pressing structure, including a fixing seat, a punching table mounted on the fixing seat through a mounting rod, and a pressing table set on the punching table. tight structure and punching structure; the punching platform is provided with a lower punching hole; the punching structure includes a punching cylinder with a punching rod vertically downwards, a punching plate installed at the end of the punching rod of the punching cylinder and a A stamping tool adapted to the position of the lower punching hole on the stamping plate; the pressing structure includes a pressing oil cylinder, and the hydraulic rod of the pressing oil cylinder is arranged vertically downward; and the pressing plate is also provided with There is a through hole, the hydraulic rod of the pressing oil cylinder passes through the through hole and extends below the stamping plate, and the end of the hydraulic rod is equipped with a pressing plate, which is the same size and shape as the stamping table, and is pressed tightly. An upper punching hole adapted to the position of the lower punching hole is arranged on the plate.

As a preference, there are two sets of the pressing oil cylinders, which are symmetrically arranged on the left and right sides of the stamping oil cylinder, and there are two through holes on the stamping plate, which are arranged on both sides of the stamping plate to match.

As a preference, the thickness of the pressing plate is set to be half of the thickness of the stamping plate; both the pressing plate and the stamping plate should be kept flat, and the thickness should not be too thick, so as to facilitate the compression of the pressing plate.

Preferably, the stamping tool on the stamping plate is set as a detachable tool.

Beneficial effects: Compared with the traditional technical solution, the utility model has the following beneficial effects: when the utility model is working, the workpiece plate is placed on the designated position of the stamping plate, so that the mounting hole to be processed is placed on the upper punching hole At the corresponding position, first press the pressing plate to press the plate parts through the operation of the pressing cylinder, and then open the pressing oil cylinder to drive the stamping tool to punch down to complete the punching action of the hole, and the waste after stamping is cleaned out from the space supported by the support rod. It is very convenient to clean up the waste; in this way, the whole plate workpiece is pressed tightly during stamping, and the stamped edge will not be damaged due to a large external force, and the device is pressed by an oil cylinder, the operation process is simple, the pressing positioning is accurate, and the pressing Strong tightening force, no sliding, easy to use.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, further clarifies the utility model, and this embodiment implements under the premise of the technical solution of the utility model, and it should be understood that these examples are only used to illustrate the utility model and are not intended to limit the utility model range.

As shown in Figure 1, a punching device with a pressing structure includes a fixed base 1, a punching table 3 mounted on the fixing base 1 through a mounting rod 2, and a pressing structure and a punching table arranged on the punching table 3. Hole structure; the punching platform 3 is provided with a lower punching hole 31; the punching structure includes a punching cylinder 4 with the punching rod arranged vertically downward, a punching plate 5 installed at the end of the punching rod of the punching cylinder 4, and The stamping tool 6 that is installed on the stamping plate 5 and adapted to the position of the lower punching hole 31; the pressing structure includes a pressing cylinder 7, and the hydraulic rod of the pressing cylinder 7 is arranged vertically downward; The stamping plate 5 is also provided with a through hole 8, the hydraulic rod of the pressing oil cylinder 7 passes through the through hole 8 and extends to the bottom of the stamping plate 5, and the end of the hydraulic rod is equipped with a pressing plate 9, the pressing The plate 9 has the same size and shape as the stamping platform 3 , and the pressing plate 9 is provided with an upper punching hole 91 matching the position of the lower punching hole 31 .

There are two sets of the pressing cylinder 7, which are arranged symmetrically on the left and right sides of the stamping cylinder 4, and there are two through holes 8 on the stamping plate 5, which are matched on both sides of the stamping plate 5; The thickness of described pressing plate 9 is set to the half of stamping plate 5 thickness; Described pressing plate 9 and stamping plate 5 all will keep smooth, and thickness is all unsuitable thicker, is convenient to the compressing of pressing plate 9; The punching cutter 6 on the punching plate 5 described above is set as a detachable cutter.

When the utility model works, the workpiece plate is placed on the designated position of the stamping plate, so that the mounting hole to be processed is placed at the position corresponding to the upper punching hole, and the pressing plate is pressed against the plate parts by pressing the oil cylinder first, and then opened Through the stamping oil cylinder, the stamping tool is driven to punch down to complete the punching action of the hole, and the waste after stamping is cleaned out from the space supported by the support rod, which is very convenient to clean up the waste; in this way, the whole plate workpiece is compressed during stamping, and the edge of the stamped It will not be damaged due to large external force, and the device adopts oil cylinder operation and compression, the operation process is simple, the compression positioning is accurate, the compression force is large, it will not slide, and it is convenient to use.
