Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinet processing, in particular to a punching device. Background Art

[0002] The harness box used inside the electric control cabinet is usually a concave structure, and in order to facilitate the lead-out of the wires, waist-shaped holes need to be processed on both sides. Of course, some harness boxes are injection molded products, so the above operation does not exist. Some use iron products to protect the wires. The existing punching device needs to use an external pushing mechanism such as a cylinder to push the concave part to move and feed when punching. This method reduces the efficiency of punching because it needs to wait for the concave part to be fed first before punching. Utility Model Content

[0003] The utility model provides a punching device to solve the above-mentioned deficiencies of the prior art, facilitates the punching operation, and can perform the feeding operation in time during the punching, thereby improving the punching efficiency and having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] A punching device includes a concave liner, which plays a guiding and limiting role for the concave part when punching the concave part. A plurality of waist-shaped holes are provided at one end of the concave liner. A lower plate is also installed at one end of the concave liner, and a pair of vertical side plates are installed on the lower plate. A plurality of guide rods are respectively passed through the vertical side plates. An inner plate is provided at the inner end of the guide rod on the same side, and a pair of vertical plates are provided on the outer wall of the inner plate. A vertical hole is provided at the upper end of the vertical plate, and an inclined hole is connected at the lower end of the vertical hole. A movable rod is movably provided in the inclined hole and the vertical hole, and a concave plate is provided on the movable rod. A downward pressure cylinder is provided at the upper end of the concave plate, and the lower end of the inclined hole extends outwardly. A plurality of waist-shaped plates are provided at the lower end of the inner wall of the inner plate. The waist-shaped plate passes through the waist-shaped hole, and the lower plate is installed with a vertical plate. A rectangular hole is opened on the vertical plate. A plurality of spring pins are arranged on the inner wall of the vertical plate. A spring is sleeved at the root of the spring pin. A push plate is arranged at the other end of the spring. The push plate is sleeved on the spring pin. An inclined plate is installed on the inner wall of the push plate. Positioning cylinders are installed on both sides of the lower end of the push plate. The inner wall of the inclined plate is an inclined surface, and the upper end of the inclined surface extends outwardly. A pushing seat is installed on one side of the concave plate, and a push wheel is installed on the push seat. The outer periphery of the push wheel is tangent to the inclined surface. When the concave plate moves downward under the drive of the downward pressure cylinder, the push wheel will first contact the inclined surface, and start the positioning cylinder, so that the positioning cylinder will penetrate into the waist-shaped perforation that has been punched. During the process of punching and pressing, the push plate and the concave part can be fed forward. When punching, the push wheel contacts the vertical surface at the lower end of the inner wall of the inclined plate. Before the punching operation is completed, the concave part will not move. When the concave part continues to move, the movable rod will act on the inclined hole, so that the waist-shaped plate will punch both sides of the concave part. After the punching is completed, the push plate moves to the initial position under the action of the spring, and the waist-shaped plate will be pulled out.

[0006] Furthermore, support platforms are formed on both sides of the concave liner to support and limit the lower end of the concave member.

[0007] Furthermore, a plurality of guide sleeves are arranged on the vertical side plates, and the guide rods are inserted into the guide sleeves. The guide sleeves play a role of strengthening the guidance.

[0008] Furthermore, a pressing block is installed on the lower wall of the transverse section of the concave plate, and the pressing block limits the concave part when punching to ensure the accuracy of the punching.

[0009] The advantages of the above technical solution are:

[0010] The utility model facilitates the forming of waist-shaped perforations on concave parts, and utilizes the gap of punching action to feed the concave parts, thereby improving the punching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

An inner plate 22 is provided at the inner end of the guide rod 21 located on the same side, and a pair of vertical plates 23 are provided on the outer wall of the inner plate 22. A vertical hole 24 is opened at the upper end of the vertical plate 23, and the lower end of the vertical hole 24 is connected with an inclined hole 25. A movable rod 26 is movably provided in the inclined hole 25 and the vertical hole 24, and a concave plate 29 is provided on the movable rod 26. A downward pressure cylinder 28 is provided at the upper end of the concave plate 29, and the lower end of the inclined hole 25 extends outwardly. A plurality of waist-shaped plates 27 are provided at the lower end of the inner wall of the inner plate 22, and the waist-shaped plates 27 are passed through the waist-shaped holes 10. The lower plate 2 is provided with a vertical plate 31, a rectangular hole 32 is opened on the vertical plate 31, a plurality of spring pins 33 are provided on the inner wall of the vertical plate 31, a spring 35 is sleeved at the root of the spring pin 33, a push plate 34 is provided at the other end of the spring 35, positioning cylinders 36 are installed on both sides of the lower end of the push plate 34, the push plate 34 is sleeved on the spring pin 33, an inclined plate 40 is installed on the inner wall of the push plate 34, the inner wall of the inclined plate 40 is an inclined surface, and the upper end of the inclined surface extends outwardly, a pushing seat is installed on one side of the concave plate 29, a pushing wheel is installed on the pushing seat, the outer periphery of the pushing wheel is tangent to the inclined surface, and a lower pressure block 30 is installed on the lower wall of the transverse section of the concave plate 29.

[0017] When operating the embodiment, the operator places the bent concave member on the concave liner 1, with one end of the bent concave member located at the waist-shaped hole 10, and then starts the downward pressure cylinder 28. Driven by the downward pressure cylinder 28, the concave plate 29 moves downward. When moving downward, the movable rod 26 first moves in the vertical hole 24, and then the waist-shaped plate 27 will be in a stopped state.
