Description
Technical Field
[0001] This application relates to the field of automotive parts processing technology, and specifically discloses a punching device for thin plates of automotive parts. Background Technology
[0002] Automotive parts are the various components that make up a car and the products that serve the car. There are many types of automotive parts, and as people's living standards improve, the demand for cars is also increasing dramatically, leading to the rapid development of automotive parts manufacturing.
[0003] Existing punching devices for thin sheet metal in automotive parts typically use a punch to directly impact the sheet metal to create holes. However, during the punching process of thin sheet metal in automotive parts, due to the small thickness of the sheet metal itself, the edges of the holes are easily deformed by the impact force when the punch punches the sheet metal, resulting in damage to the structural shape of the sheet metal and affecting the use of the thin sheet metal in automotive parts. Therefore, in view of this, the inventor provides a punching device for thin sheet metal in automotive parts to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to solve the problem that during the punching process of traditional thin plates, the edges of the holes are easily deformed by impact forces, causing localized damage to the structure and affecting the use of the thin plates.
[0005] To achieve the above objectives, the basic solution of this utility model provides a punching device for thin plates of automotive parts, including a fixed base plate, a punching mechanism and a controller mounted on the fixed base plate. One side of the fixed base plate is provided with a mounting plate, and the other side of the mounting plate is provided with a mounting top plate located above the fixed base plate. The punching mechanism includes a hydraulic punch located on the bottom side of the mounting top plate, a punching base mounted on the fixed base plate for placing the thin plates of automotive parts, and multiple die holes formed on the punching base. The punching base is located directly below the hydraulic punch. The fixed base plate also has a die for punching the thin plates. The pressing mechanism for flattening includes a pressing base frame connected to one side of the punching base frame, a pressing plate located above the pressing base frame, and a pressing hydraulic rod installed between the pressing plate and the mounting top plate. The hydraulic punch and the pressing hydraulic rod are electrically connected to the controller. The pressing base frame is flush with the top surface of the punching base frame. The fixed base plate is provided with clamping parts for clamping and fixing the thin plate. The fixed base plate is also provided with a material transfer mechanism for moving the thin plate from the punching base frame to the pressing base frame. The mounting top plate is provided with a positioning mechanism for driving the hydraulic punch and the pressing hydraulic rod to move longitudinally.
[0006] The principle and effect of this basic scheme are as follows:
[0007] 1. Compared with the prior art, this utility model features a punching structure. A punching base provides structural support for the thin plate requiring punching. Simultaneously, by setting die holes on the punching base, not only is punching of the thin plate convenient, but structural support is also provided for the remaining structural parts of the thin plate besides the punched areas. This prevents the remaining structural parts of the thin plate from deforming under stress. Furthermore, by setting a pressure base and pressure plate, the thin plate after punching is pressure-treated, thereby unifying and correcting the thickness of the thin plate, preventing deformation of the hole edges, resulting in better finished product quality and improved usability. This solves the problem that in traditional thin plate punching processes, the edges of the holes are easily deformed by impact forces, causing localized structural damage and affecting the use of the thin plate.
[0008] 2. Compared with the prior art, this utility model realizes the integrated processing of punching and structural repair of thin plates by setting a material transfer mechanism to move the thin plate, which improves the working efficiency of thin plate production. By setting a positioning mechanism, it is easy to position the punching processing at different positions of the thin plate. At the same time, it is easy for the working area of the pressing mechanism to be synchronously positioned with the punching area of the thin plate, which further improves the processing efficiency of the thin plate.
[0009] Furthermore, the punching base frame includes a punching support plate located between the fixed base plate and the mounting top plate, and a plurality of punching support columns disposed between the bottom side of the punching support plate and the fixed base plate. The die holes are evenly distributed on the punching support plate. The pressing base frame includes a pressing support plate located between the fixed base plate and the mounting top plate, and a plurality of pressing support columns disposed between the bottom side of the pressing support plate and the fixed base plate. The surfaces of the pressing support plate and the punching support plate are flush and of equal thickness. By setting the punching support columns and the punching support plate, the die holes are suspended, which facilitates the discharge of waste generated after the thin plate is punched from the punching support plate, avoiding the waste from hindering the movement of the thin plate during punching. By setting the pressing support plate and the punching support plate to be flush and of equal thickness, the thin plate can be more easily moved after processing, facilitating subsequent pressing processing.
[0010] Furthermore, the clamping components include guide frames symmetrically arranged on the fixed base plate and located on both sides of the punching base frame and the pressing base frame; clamping slides slidably connected to the guide frames and used to support the bottom surfaces of both ends of the thin plate; and side clamping plates provided on the surface of the clamping slides and used to clamp the same end of the thin plate. Each surface of the clamping slide is provided with an electric lifting rod located inside the side clamping plates and used to adjust the clamping height of the thin plate. The electric lifting rod is electrically connected to a controller. By providing clamping slides and side clamping plates, the thin plate is easily limited and clamped. By being located on the guide frames, the position of the thin plate on the fixed base plate is easily adjusted.
[0011] Furthermore, the guide frame includes a guide rail disposed above the fixed base plate and located outside the punching base frame and the pressing base frame, and a plurality of guide support columns evenly disposed between the fixed base plate and the guide rail. By setting the guide rail and guide support columns, the clamping component is installed in the air, which not only facilitates the use of the clamping slide.
[0012] Furthermore, the material transfer mechanism includes a first linear drive module mounted on a guide rail and used to drive the clamping slide along the guide rail. The first linear drive module is electrically connected to the controller. By setting the first linear drive module to drive the thin plate to slide between the punching base and the pressing base, the pressing processing of the thin plate is facilitated, and the operation is simple and efficient.
[0013] Furthermore, the positioning mechanism includes a second linear drive module mounted on one side of the mounting top plate and a positioning slide plate mounted on the second linear drive module. The hydraulic punch and the pressure hydraulic rod are both mounted on the bottom side of the positioning slide plate. One end of the positioning slide plate is driven to slide by the second linear drive module, and the other end of the positioning slide plate is slidably connected to the other side of the mounting top plate. By setting the second linear drive module to drive the linear movement of the positioning slide plate, and simultaneously mounting the hydraulic punch and the pressure hydraulic rod on the positioning slide plate, synchronous adjustment of the punching position and the pressure position is achieved, thereby facilitating the corresponding linear movement of the sheet metal by the material transfer mechanism.

[0026] In the specific implementation of this utility model, before punching the thin plate 7, the punching position of the thin plate 7 is marked, and the thin plate 7 is installed on the punching support plate 11.
