Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to a sheet metal edge scrap punching device. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets, including shearing, punching, bending, welding, riveting, splicing, and forming. Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. After the sheet metal parts are stamped and formed, the excess material on the edges of the sheet metal parts needs to be punched off to make the parts meet the final size and shape requirements.

[0003] Traditional punching devices have poor adaptability to sheet metal parts of different sizes and shapes. Typically, a single die set can only punch sheet metal parts of a specific size. When processing sheet metal parts of different sizes or shapes, the entire die set must be changed. This not only consumes a lot of time and manpower and results in low production efficiency, but also, most existing punching devices lack waste collection capabilities. Waste generated during punching is scattered randomly, polluting the working environment and increasing the difficulty and workload of cleanup. Therefore, a sheet metal edge waste punching device is proposed to solve the problems mentioned above. Utility Model Content

[0004] To solve the above-mentioned technical problems, a sheet metal edge scrap punching device is provided. This technical solution solves the problems mentioned in the background art, such as the punching device being unable to adapt to sheet metal of different sizes and shapes, resulting in low production efficiency and pollution of the working environment.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sheet metal edge scrap punching device includes a base, with legs fixedly connected to the four corners of the lower surface of the base. A scrap collection hopper is provided at the lower end of the base. A base is fixedly installed on the upper surface of the base to the left of the scrap collection hopper. Side plates are fixedly installed on both the front and rear sides of the base. A guide rail is provided on one side of each of the two side plates. Three hydraulic rods are fixedly installed on the upper surface of the base. A cutting table is fixedly connected to the output end of the three hydraulic rods. Several lower support columns are fixedly installed on the upper surface of the base to the left of the guide rails.

[0007] Preferably, a fixing frame is fixedly installed on the upper surface of the base outside the side plate. Guide rails are provided on both inner walls of the fixing frame. A hydraulic rod is fixedly installed on the inner top of the fixing frame. A crossbeam is fixedly connected to the output end of the hydraulic rod. A top plate is fixedly installed on the right side of the crossbeam. A cutter is fixedly installed on the lower surface of the top plate. Several upper support columns are fixedly installed on the left side of the lower surface of the top plate.

[0008] Preferably, the cutting table is slidably connected inside the two guide rails.

[0009] Preferably, the crossbeam is slidably connected inside the two guide rails.

[0010] Preferably, the lower support includes a lower inner rod fixedly connected to the upper end of the base, a lower outer rod sleeved on the outer surface of the lower inner rod, a lower support block fixedly installed at the upper end of the lower outer rod, and a lower spring fixedly installed between the lower outer rod and the base.

[0011] Preferably, the upper support includes an upper inner rod fixedly connected to the lower end of the top plate, an upper outer rod sleeved on the outer surface of the upper inner rod, an upper support block fixedly installed at the lower end of the upper outer rod, and an upper spring fixedly installed between the upper outer rod and the top plate.

[0012] Compared with the prior art, the present invention provides a sheet metal edge scrap punching device, which has the following beneficial effects:

[0013] This invention utilizes a mold assembly with adaptive size and shape, comprising several upper supports and several lower supports. Before the punching operation, the sheet metal part is placed on the lower supports, at which point the lower springs shorten under pressure. When the lower supports contact the irregular surface of the sheet metal part, the lower springs undergo varying degrees of elastic deformation according to the surface condition. Subsequently, hydraulic rod two is activated, pushing the top plate to move the upper supports towards and closer to the sheet metal part. When these upper supports contact the irregular surface of the sheet metal part, they also undergo varying degrees of elastic deformation to adapt to it, thus achieving adaptive adjustment for sheet metal parts of different sizes and shapes, thereby meeting the requirements of the punching process.

[0014] This invention features a waste collection hopper, into which waste generated during the punching process falls directly. The hopper's side walls are designed to allow the waste to slide smoothly. The hopper's body has a drawer-style structure for easy removal and cleaning of the waste. This effectively collects the waste, keeps the working environment clean, and reduces cleaning workload. Attached Figure Description

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figures 1-6As shown, a sheet metal edge scrap punching device includes a base 1. Support legs 2 are fixedly connected to the four corners of the lower surface of the base 1. A scrap collection hopper 3 is provided at the lower end of the base 1. Scrap generated during the punching process falls directly into the scrap collection hopper 3. The side walls of the scrap collection hopper 3 are inclined to facilitate the smooth sliding of scrap. The casing of the scrap collection hopper 3 adopts a drawer-type structure for easy removal and cleaning of scrap. Scrap is effectively collected, keeping the working environment clean and reducing cleaning workload. A base 4 is fixedly installed on the upper surface of the base 1, to the left of the scrap collection hopper 3. Side plates 5 are fixedly installed on both the front and rear sides of the base 4. Guide rails 9 are provided on opposite sides of the two side plates 5. Several lower support columns 6 are fixedly installed on the upper surface of the base 4, to the left of the guide rails 9. The lower support column 6 includes a lower inner rod 601 fixedly connected to the upper end of the base 4. A lower outer rod 602 is sleeved on the outer surface of the lower inner rod 601. A limit clip is provided at the upper end of the lower inner rod 601. A lower support block 603 is fixedly installed at the upper end of the lower outer rod 602. To avoid damage to the surface of the sheet metal part, the lower support block 603 is made of elastic material. A lower spring 604 is fixedly installed between the lower outer rod 602 and the base 4. Before performing the punching operation, the sheet metal part is placed on the lower support column 6. At this time, the lower spring 604 is shortened by the weight of the sheet metal part itself. When the lower support block 603 contacts the irregular surface of the sheet metal part, the lower spring 604 will produce different degrees of elastic deformation according to the surface condition. The waste edge of the sheet metal part to be cut is located above the waste collection hopper 3.

[0025] A mounting bracket 10 is fixedly installed on the upper surface of the base 1, outside the side plate 5. Guide rails 12 are provided on both inner walls of the mounting bracket 10. A hydraulic rod 11 is fixedly installed at the top inner side of the mounting bracket 10. A crossbeam 13 is fixedly connected to the output end of the hydraulic rod 11, and the crossbeam 13 is slidably connected inside the two guide rails 12. A top plate 14 is fixedly installed on the right side of the crossbeam 13. A cutter 15 is fixedly installed on the lower surface of the top plate 14. Several upper support columns 16 are fixedly installed on the lower surface of the top plate 14, to the left of the cutter 15. The upper support column 16 is taller than the cutter 15, and the two will not interfere with each other during operation. The upper support column 16 includes an upper inner rod 1601 fixedly connected to the lower end of the top plate 14. An upper outer rod 1602 is sleeved on the outer surface of the upper inner rod 1601. A limit clip is provided at the lower end of the upper inner rod 1601. An upper support block 1603 is fixedly installed at the lower end of the upper outer rod 1602. To avoid damage to the surface of the sheet metal part, the upper support block 1603 is made of elastic material. An upper spring 1604 is fixedly installed between the upper outer rod 1602 and the top plate 14. When the hydraulic rod 11 is activated, the top plate 14 is pushed, causing the upper support column 16 to move towards and approach the sheet metal part. When it comes into contact with the irregular surface of the sheet metal part, the upper spring 1604 will also undergo different degrees of elastic deformation to match it.

[0026] Three hydraulic rods 7 are fixedly mounted on the upper surface of the base 4. The output ends of the three hydraulic rods 7 are fixedly connected to a cutting table 8, which is slidably connected inside two guide rails 9. Before the punching operation, the hydraulic rods 7 are in a retracted state. After the sheet metal part is clamped, the hydraulic rods 7 are activated. The hydraulic rods 7 then drive the cutting table 8 to move towards the lower surface of the sheet metal part to be punched until the cutting table 8 abuts against the lower surface of the sheet metal part. Throughout the punching operation, the cutting table 8 provides support for the sheet metal part, ensuring the stability and accuracy of the punching process.

[0027] Working Principle: In use, the sheet metal part is first placed on the lower support column 6. At this time, the lower spring 604 is shortened under pressure. When the lower support block 603 contacts the irregular surface of the sheet metal part, the lower spring 604 will produce different degrees of elastic deformation according to the surface condition. Then, the hydraulic rod 11 is activated, pushing the top plate 14 to move the upper support column 16 towards the sheet metal part and close to it. When it contacts the irregular surface of the sheet metal part, the upper spring 1604 will also produce different degrees of elastic deformation to match it. After the sheet metal part is clamped, the hydraulic rod 7 is activated. The hydraulic rod 7 then drives the cutting table 8 to move towards the lower surface of the sheet metal part to be punched until the cutting table 8 and the lower surface of the sheet metal part to be punched come into contact with each other. During the entire punching operation, the cutting table 8 plays a supporting role for the sheet metal part, ensuring the stability and accuracy of the punching process. Waste generated during the punching process falls directly into the waste collection hopper 3. The side wall of the waste collection hopper 3 is designed with an inclination to facilitate the smooth sliding of waste. The body of the waste collection hopper 3 adopts a drawer-type structure, which makes it easy to remove and clean the waste. The waste is effectively collected, keeping the working environment clean and reducing the amount of cleaning work.
