Description

Technical Field

[0001] This utility model relates to the field of punching device technology, and in particular to a punching device for sheet metal processing. Background Technology

[0002] Punching is an important process in sheet metal processing, which involves punching holes of the required shape and size into sheet metal parts. Punching allows for the fulfillment of functional requirements in various products, such as mounting, ventilation, and heat dissipation.

[0003] The sheet metal punching equipment mentioned in the existing Chinese patent (authorization announcement number: CN220049666U) uses a punch with a cutting edge at the bottom and a punch angle of 15 to 30 degrees. This concentrates the cutting force generated when cutting the sheet metal part on the bottom edge of the punch cutting edge, making the cutting force more concentrated at the cutting edge. The cross-sectional area of ​​the pressure plate is smaller than the cross-sectional area of ​​the workpiece groove. The power component first drives the pressure plate to press the workpiece. The force exerted by the pressure plate on the workpiece is between the ejector force and the punching force, so that the pressure plate compacts the area near the area to be cut.

[0004] When punching sheet metal parts, the upper die is driven by a drive device to make the lower die press against the upper die, so that the sheet metal part has a hole that is the same as the upper die, thus completing the punching process. However, when punching sheet metal parts, the impact force generated by the upper die pressing down can easily cause the sheet metal part to shift, which may cause the sheet metal part to deviate from the predetermined coordinates, making it difficult to meet the hole position accuracy requirements of subsequent assembly processes. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the impact force generated by the downward pressing of the upper template can easily cause the sheet metal parts to shift, which may cause the sheet metal parts to deviate from the predetermined coordinates. This utility model provides a punching device for sheet metal parts processing.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A punching device for sheet metal processing includes a worktable, a fixed plate fixedly connected to the top of the worktable, a fixed plate fixedly connected to the top of the fixed plate, a hydraulic telescopic rod fixedly connected to the top of the fixed plate, the output end of the hydraulic telescopic rod passing through the fixed plate and fixedly connected to an upper mold, a lower mold fixedly connected to the top of the worktable, a positioning mechanism symmetrically arranged on the top of the upper and lower molds, and a collecting mechanism arranged on the top of the worktable.

[0008] By adopting the above technical solution, the sheet metal part is placed on the lower mold, and then the hydraulic telescopic rod is activated to drive the upper mold to move downward, thereby punching the material on the lower mold. The waste material after punching will fall onto the worktable, thus completing the punching process. The positioning mechanism can reduce the risk of the sheet metal part moving during the punching process, and the collection mechanism can collect the fallen waste material.

[0009] Furthermore, the positioning mechanism includes vertical plates symmetrically fixedly connected to the top of the worktable, electric push rods fixedly connected to the sides of the two vertical plates that are close to each other, and abutment plates fixedly connected to the sides of the two electric push rods that are close to each other. The bottom of the abutment plates is slidably disposed with the lower mold.

[0010] By adopting the above technical solution, the electric push rod is activated to move the contact plate, so that the two contact plates move closer to each other, thereby positioning the sheet metal part placed on the lower mold and reducing the risk of displacement of the sheet metal part during the punching process.

[0011] Furthermore, guide rods are fixedly connected to the opposite sides of the two contact plates, and the opposite ends of the two guide rods penetrate the vertical plate, with the guide rods slidably connected to the vertical plate.

[0012] By adopting the above technical solution, the guide rod provides an additional support point for the contact plate, so that the sheet metal parts can remain stable when moving.

[0013] Furthermore, a top plate is fixedly connected to the top of the contact plate, a reinforcing frame is fixedly connected to the top of the top plate, a movable plate is slidably connected to the inner side of the reinforcing frame, a vertical rod is fixedly connected to the bottom of the movable plate, the bottom end of the vertical rod penetrates the top plate, the outer side of the vertical rod is set to be inclined, and the vertical rod is slidably connected to the top plate.

[0014] By adopting the above technical solution, the elastic potential energy of the spring is released, which allows the vertical rod to clamp the sheet metal part, further improving the stability of the sheet metal part during processing.

[0015] Furthermore, the inner side of the fixed frame is provided with a pair of sliding grooves, and the outer side of the movable plate is symmetrically fixedly connected with sliders, which are slidably connected to the sliding grooves.

[0016] By adopting the above technical solution, the slider and the groove provide guidance for the moving plate, so that the moving plate can maintain the correct motion trajectory when moving.

[0017] Furthermore, the collection mechanism includes a through hole on the top of the workbench, a horizontal plate is fixedly connected to the inner side of the workbench, a collection box is placed on the top of the horizontal plate, the top of the collection box is set to be open, and the top of the collection box is adapted to the through hole.

[0018] By adopting the above technical solution, when the waste falls, it will move downward through the through hole under the action of gravity, and then the top of the collection box is set to be open, so that the waste can enter the collection box for collection.

[0019] In summary, this utility model has at least one of the following beneficial effects;

[0020] 1. In this utility model, when positioning sheet metal parts, the electric push rod is activated to drive two contact plates to move closer to each other, thereby positioning the sheet metal parts placed on the lower mold, reducing the risk of displacement of the sheet metal parts during the punching process, and ensuring that the position of the punched hole matches the design requirements, thereby achieving precise assembly between subsequent components.

[0021] 2. In this utility model, when waste falls, it will move downward through the through hole under the action of gravity, and then the top of the collection box is set to be open, so that the waste can enter the collection box for collection, which facilitates the timely collection and emptying of waste.

[0028] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0029] This utility model discloses a punching device for sheet metal processing.

[0030] Reference Figure 1 and Figure 2A punching device for sheet metal processing includes a worktable, a fixed plate fixedly connected to the top of the worktable, a fixed plate fixedly connected to the top of the fixed plate, a hydraulic telescopic rod fixedly connected to the top of the fixed plate, the output end of the hydraulic telescopic rod passing through the fixed plate and fixedly connected to an upper mold, a lower mold fixedly connected to the top of the worktable, a positioning mechanism symmetrically arranged on the top of the worktable, and a collecting mechanism arranged on the top of the worktable.

[0031] When punching materials, the sheet metal part is first placed on the lower mold. Then, the hydraulic telescopic rod is activated to move the upper mold downward, thereby punching the material on the lower mold. The waste material after punching will fall onto the worktable, thus completing the punching process. The positioning mechanism can reduce the risk of the sheet metal part moving during the punching process, and the collection mechanism can collect the fallen waste material.

[0032] Reference Figures 1 to 4 The positioning mechanism includes vertical plates that are symmetrically fixedly connected to the top of the worktable. Electric push rods are fixedly connected to the side of the two vertical plates that are close to each other. Abutment plates are fixedly connected to the side of the two electric push rods that are close to each other. The bottom of the abutment plates is slidably set with the lower mold.

[0033] Among them, the two contact plates are fixedly connected to the opposite sides of each other with guide rods, and the opposite ends of the two guide rods pass through the vertical plate, and the guide rods are slidably connected to the vertical plate.

[0034] In addition, a top plate is fixedly connected to the top of the contact plate, a reinforcing frame is fixedly connected to the top of the top plate, a movable plate is slidably connected to the inner side of the reinforcing frame, a vertical rod is fixedly connected to the bottom of the movable plate, the bottom end of the vertical rod penetrates through the top plate, the outer side of the vertical rod is set to be inclined, and the vertical rod is slidably connected to the top plate.

[0035] Furthermore, the inner side of the fixed frame is provided with a pair of sliding grooves, and the outer side of the movable plate is symmetrically fixed with sliders, which are slidably connected to the sliding grooves.

[0036] When positioning sheet metal parts, the sheet metal parts are first placed on the lower mold. Then, the electric push rod is activated to move the abutment plate, so that the two abutment plates move closer to each other, thereby positioning the sheet metal parts placed on the lower mold. This reduces the risk of displacement of the sheet metal parts during the punching process, and ensures that the position of the punched hole matches the design requirements, thereby achieving precise assembly between subsequent components.

[0037] When the contact plate moves, the guide rod provides additional support points for the contact plate, so that the sheet metal part can remain stable when moving.

[0038] When the contact plate moves, the sheet metal part will contact the vertical rod. The outer side of the vertical rod is set to be inclined. The sliding action of the inclined surface causes the vertical rod to move upward. The upward movement of the vertical rod drives the moving plate to move within the reinforcing frame. The movement of the moving plate will compress the spring, causing the spring to compress and generate elastic potential energy. When the sheet metal part moves to below the vertical rod, the elastic potential energy of the spring is released, allowing the vertical rod to clamp the sheet metal part, further improving the stability of the sheet metal part during processing.

[0039] When the moving plate moves, the slider and the groove provide guidance, allowing the moving plate to maintain the correct motion trajectory.

[0040] Reference Figure 1 and Figure 2 The collection mechanism includes a through hole on the top of the workbench, a horizontal plate fixedly connected to the inside of the workbench, a collection box placed on the top of the horizontal plate, the top of the collection box being open, and the top of the collection box being adapted to the through hole.

[0041] When collecting waste, the collection box is first placed on a horizontal plate. When the waste falls, it will move downward through the through hole under the action of gravity. The top of the collection box is set to be open, so that the waste can enter the collection box for collection. This makes it convenient for the waste to be collected and emptied in a timely manner, reduces the cleaning time in the production process, and improves work efficiency.

[0042] Working principle: The sheet metal part is placed on the lower mold. Then, the hydraulic telescopic rod is activated to move the upper mold downward, thereby punching the material on the lower mold. The waste material after punching will fall onto the worktable, thus completing the punching process. The sheet metal part is placed on the lower mold, and then the electric push rod is activated to move the abutment plate, so that the two abutment plates move closer to each other, thereby positioning the sheet metal part placed on the lower mold, reducing the risk of displacement of the sheet metal part during the punching process, and ensuring that the position of the punched hole matches the design requirements.
