Description

Technical Field

[0001] This utility model relates to the field of sheet metal for power cabinets, specifically to a punching and corner cutting device for sheet metal processing of power cabinets. Background Technology

[0002] Sheet metal for power cabinets refers to the metal plates inside the power cabinet, usually made of materials such as cold-rolled thin steel plates, electrolytic plates, and aluminum alloy plates. It is an important component of the power cabinet. During the processing of sheet metal for power cabinets, punching and chamfering are required to meet the required shapes and hole positions inside the power cabinet.

[0003] Existing punching and corner cutting devices for power cabinet sheet metal processing mostly separate punching and corner cutting during the power cabinet sheet metal processing process, rarely combining the two. This results in the power cabinet sheet metal being punched first, and then the punched power cabinet sheet metal being placed on the corner cutting device for corner cutting. This not only delays the power cabinet sheet metal processing efficiency, but is also too cumbersome.

[0004] Therefore, it is necessary to invent a punching and corner-cutting device for sheet metal processing of power cabinets to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a punching and corner-cutting device for power cabinet sheet metal processing. The device involves placing the power cabinet sheet metal on a placement table, then opening four sets of cylinder switches in the fixed frame inside the placement table to push a support plate against the underside of the power cabinet sheet metal. Next, opening the first hydraulic cylinder switch above the fixed bracket pushes the first and second connecting seats and the punch to punch holes in the surface of the power cabinet sheet metal. After punching, opening the second hydraulic cylinders on both sides above the fixed bracket pushes the entire connecting bracket and the cutting heads at the four corners below to cut the corners of the power cabinet sheet metal. This allows for corner cutting immediately after punching, improving the overall processing practicality and solving the problem mentioned in the background art of existing punching and corner-cutting devices for power cabinet sheet metal processing. In most cases, punching and corner cutting are done separately during power cabinet sheet metal processing, rarely combining the two. This results in the power cabinet sheet metal being punched first, and then placed on a corner-cutting device for corner cutting, which not only delays the processing efficiency but is also overly cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching and corner-cutting device for sheet metal processing of power cabinets, including a main frame for supporting the punching and corner-cutting device;

[0007] A placement platform, located inside the main frame, is used to place the power cabinet sheet metal. Waste troughs are opened on both sides of the inner surface of the placement platform.

A fixed bracket is fixedly connected to the upper rear side of the main frame. A first hydraulic cylinder is fixedly installed above the fixed bracket. A first connecting seat is fixedly connected to the lower end of the first hydraulic cylinder. A second connecting seat is provided below the first connecting seat. A punch is provided below the second connecting seat.

[0008] The corner-cutting mechanism is installed below the fixed bracket and is used for cutting corners on the sheet metal of the power cabinet.

[0009] Preferably, the support assembly includes a fixed frame, with cylinders fixedly connected to the upper perimeter of the fixed frame, and a support plate fixedly connected to the upper end of each cylinder.

[0010] Preferably, slide rods are fixedly connected to the upper two sides of the first connecting seat, and the slide rods are slidably connected to the fixed bracket. A first movable rod is fixedly connected to the upper four sides of the second connecting seat, and the first movable rod is slidably connected to the first connecting seat. A first spring is sleeved on the outside of the first movable rod.

[0011] Preferably, the corner-cutting mechanism includes a second hydraulic cylinder, which is disposed on both sides above the fixed bracket. A connecting bracket is fixedly connected to the lower end of the second hydraulic cylinder, and a cutting head is fixedly connected to the lower perimeter of the connecting bracket.

[0012] Preferably, a connecting block is fixedly connected to the inside of the connecting bracket, a second movable rod is movably connected inside the connecting block, a pressure block is fixedly connected to the lower end of the second movable rod, and a second spring is sleeved on the upper part of the pressure block and the outside of the second movable rod.

[0013] Preferably, the pressure block is provided in four sets, and the four sets of pressure blocks are respectively located at diagonal positions on the rear side of the cutter head.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By setting up a placement platform, support components, fixed brackets, a first hydraulic cylinder, a first connecting seat, a second connecting seat, a punch, and a corner-cutting mechanism, the power cabinet sheet metal can be directly corner-cut after punching, thereby improving the processing effect of the power cabinet sheet metal. By placing the power cabinet sheet metal on the placement platform, and then opening the four sets of cylinder switches in the fixed frame inside the placement platform, the support plate is pushed to stick to the bottom of the power cabinet sheet metal. Then, the first hydraulic cylinder switch above the fixed bracket is opened, pushing the first connecting seat, the second connecting seat, and the punch to punch the surface of the power cabinet sheet metal. After punching is completed, the second hydraulic cylinders on both sides above the fixed bracket are opened to push the entire connecting bracket and the cutting heads at the four corners below to cut the corners of the power cabinet sheet metal. In this way, corner cutting can be performed directly after punching, improving the practicality of the overall processing.

[0016] 2. With the corner cutting mechanism, when cutting the corners of the power cabinet sheet metal, the second hydraulic cylinder switch is turned on, pushing the connecting bracket and the cutting head to contact the four corners of the power cabinet sheet metal. Before cutting the corners, the four sets of second movable rods and pressure blocks inside the connecting bracket contact the inner side of the corner to be cut in advance, thereby limiting and fixing the position of the corner and preventing the edge from curling up during the corner cutting process.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The illustrated punching and corner cutting device for sheet metal processing of power cabinets includes a main frame 1 for supporting the punching and corner cutting device;

[0028] The placement platform 2 is located inside the main frame 1 and is used to place the power cabinet sheet metal. The two inner surfaces of the placement platform 2 are provided with waste troughs 3. The placement platform 2 is provided with a support component 4. The main frame 1 is slidably connected to a collection box 5. The main frame 1 is fixedly connected to a fixed bracket 6 on the upper rear side. The fixed bracket 6 is fixedly installed above the first hydraulic cylinder 7. The lower end of the first hydraulic cylinder 7 is fixedly connected to a first connecting seat 8. The first connecting seat 8 is provided below the first connecting seat 8. The second connecting seat 10 is provided below the second connecting seat 10. The punch 13 is provided below the second connecting seat 10.

[0029] The corner-cutting mechanism 14, installed below the fixed bracket 6, is used for corner cutting of the power cabinet sheet metal. By placing the power cabinet sheet metal on the placement platform 2, and then turning on the four sets of cylinder 402 switches in the fixed frame 401 inside the placement platform 2, the support plate 403 is pushed to stick to the bottom of the power cabinet sheet metal. Then, the first hydraulic cylinder 7 switch above the fixed bracket 6 is turned on, pushing the first connecting seat 8, the second connecting seat 10, and the punch 13 to punch holes in the surface of the power cabinet sheet metal. After punching, the second hydraulic cylinders 1401 on both sides above the fixed bracket 6 are turned on to push the entire connecting bracket 1402 and the cutting heads 1403 at the four corners below to cut the corners of the power cabinet sheet metal. In this way, corner cutting can be performed directly after punching, which improves the practicality of the overall processing.

[0030] like Figure 2 and Figure 3As shown, the support component 4 includes a fixed frame 401. Cylinders 402 are fixedly connected to the upper perimeter of the fixed frame 401. A support plate 403 is fixedly connected to the upper end of the cylinders 402. By opening the switch of the cylinders 402, the support plate 403 is pushed to press against the bottom of the power cabinet sheet metal, thereby providing support for the power cabinet sheet metal and giving the punch 13 a supporting effect when punching holes in the power cabinet sheet metal.

[0031] like Figure 4 and Figure 5 As shown, slide rods 9 are fixedly connected to the upper two sides of the first connecting seat 8, and slide rods 9 are slidably connected to the fixed bracket 6. The upper periphery of the second connecting seat 10 is fixedly connected to the first movable rod 11, and the first movable rod 11 is slidably connected to the first connecting seat 8. The outside of the first movable rod 11 is fitted with a first spring 12. When the switch of the first hydraulic cylinder 7 is turned on and the first connecting seat 8 is pushed to rise and fall, the slide rods 9 on the upper two sides of the first connecting seat 8 slide within the fixed bracket 6, thereby improving the stability of the first connecting seat 8 during the rising and falling process. The first movable rod 11 and the first spring 12 are provided between the first connecting seat 8 and the second connecting seat 10, which plays a buffering role for the second connecting seat 10 and the punch 13 during the punching process.

[0032] like Figure 1 , Figure 4 and Figure 6 As shown, the corner-cutting mechanism 14 includes a second hydraulic cylinder 1401, which is disposed on both sides above the fixed bracket 6. The lower end of the second hydraulic cylinder 1401 is fixedly connected to a connecting bracket 1402, and the lower four sides of the connecting bracket 1402 are fixedly connected to cutting heads 1403. After punching, the second hydraulic cylinders 1401 on both sides above the fixed bracket 6 are opened to push the entire connecting bracket 1402 and the cutting heads 1403 at the four corners below to cut the corners of the power cabinet sheet metal.

[0033] like Figure 6 As shown, connecting blocks 1404 are fixedly connected to the inside of the connecting bracket 1402. A second movable rod 1405 is movably connected inside the connecting block 1404. A pressure block 1406 is fixedly connected to the lower end of the second movable rod 1405. A second spring 1407 is sleeved on the upper part of the pressure block 1406 and the outside of the second movable rod 1405. The connecting bracket 1402 and the cutter head 1403 contact the four corners of the power cabinet sheet metal. Before cutting the corner, the four sets of second movable rods 1405 and pressure blocks 1406 inside the connecting bracket 1402 contact the inner side of the corner to be cut on the power cabinet sheet metal in advance, thereby limiting and fixing the position of the cut corner and preventing the edge from curling up during the cutting process.

[0034] like Figure 6As shown, there are four sets of pressure blocks 1406. The four sets of pressure blocks 1406 are respectively located at the diagonal rear side of the cutter head 1403. By pressing the inner side of the cut corner of the power cabinet sheet metal by the four sets of pressure blocks 1406, the stability of the cutting process is enhanced.

[0035] The working principle of this utility model is as follows: First, connect the external power supply. Then, place the power cabinet sheet metal on the placement platform 2 above the main frame 1. Next, turn on the switches of the four sets of cylinders 402 inside the placement platform 2, pushing the support plate 403 to press against the bottom of the power cabinet sheet metal. After placement, turn on the switch of the first hydraulic cylinder 7 above the fixed bracket 6, pushing the first connecting seat 8, the second connecting seat 10, and the punch 13 to punch holes in the surface of the power cabinet sheet metal. During the lifting and lowering process of the first connecting seat 8 and the second connecting seat 10, the sliding rods 9 on both sides above the first connecting seat 8 slide within the fixed bracket 6, improving the stability of the first connecting seat 8 during the lifting and lowering process. The first movable rod 11 and the first spring 12 are set around the first connecting seat 8 and the second connecting seat 10, which play a buffering role for the second connecting seat 10 and the punch 13 during the punching process. After punching, the waste material inside the power cabinet sheet metal will fall into the collection box 5 at the bottom of the main frame 1 through the groove inside the support plate 403. After the hole is punched, the switch of the first hydraulic cylinder 7 is turned off, and the device extends and retracts to its initial position. Then, the second hydraulic cylinders 1401 on both sides above the fixed bracket 6 are turned on to push the entire connecting bracket 1402 and the cutting heads 1403 at the four corners below to cut the corners of the power cabinet sheet metal. Before cutting the corners, the four sets of second movable rods 1405 and pressure blocks 1406 inside the connecting bracket 1402 contact the inner side of the corner to be cut on the power cabinet sheet metal in advance, thereby limiting and fixing the position of the corner and preventing the edge from curling during the corner cutting process. The waste material after corner cutting falls into the collection box 5 at the bottom through the waste material trough 3. After the corner cutting is completed, the switch of the second hydraulic cylinder 1401 is turned off, and the entire connecting bracket 1402 and the cutting head 1403 are raised and lowered to the highest position. Finally, the worker takes out the punched and corner-cut power cabinet sheet metal and continues to put in the next power cabinet sheet metal. Finally, when the device is no longer in use, the external power is cut off. In this way, the process of using the punching and corner-cutting device for power cabinet sheet metal processing is completed.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
