Description

Technical Field

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

[0002] Metal electrical enclosures are enclosed or semi-enclosed structures made of metal materials used to house and protect electrical equipment, components, and wiring. Their main uses include protecting internal electrical components from external physical damage (such as impacts and compression) and preventing the intrusion of dust, moisture, corrosive gases, etc.

[0003] Without a centered guide during the cutting process, metal electrical housing sheets are prone to shifting, leading to deviations in the cutting position. This results in non-compliant dimensions of the cut sheets, uneven cuts, and excessive burrs. Therefore, we need to design a sheet cutting device for metal electrical housings that employs a counter-clamping and guiding structure. The centered guide ensures that the sheet remains in the accurate position throughout the cutting process, strictly adhering to the preset dimensions and shape. The stable relative position with the sheet results in smoother, flatter cuts, reducing burrs and bevels, effectively preventing sheet displacement and improving the cutting quality of metal electrical housing sheets. Utility Model Content

[0004] The purpose of this invention is to provide a sheet metal cutting device for metal electrical housings. This device employs a counter-clamping and guiding structure, with the guide centered to ensure the sheet metal remains in the correct position during cutting. Cutting is performed strictly according to preset dimensions and shapes, maintaining a stable relative position with the sheet metal, resulting in smoother, flatter cuts and reducing burrs and bevels. It effectively avoids sheet metal misalignment, thus improving the cutting quality of metal electrical housing sheets and solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A sheet metal cutting device for metal electrical housings includes a sheet metal cutting machine.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model places the sheet metal in the conveyor position of the sheet metal cutting machine. Then, through the cooperation of the connecting plate, rack and pinion, and gear, the two connecting blocks drive the guide rollers to move in opposite directions in a rectangular shape. The guide rollers then clamp and guide the sheet metal. Finally, the cutting direction of the sheet metal is horizontal. This achieves the purpose of using an opposite clamping and guiding structure. The centered guide ensures that the sheet metal is always in an accurate position during the cutting process, strictly cutting according to the preset size and shape. The relative position of the sheet metal is stable, the cut is flatter and smoother, and the quality defects of burrs and bevels are reduced. It can effectively avoid the sheet metal from shifting position and improve the cutting quality of metal electrical housing sheet metal.

[0013] 2. This utility model uses the cooperation of the sliding rod and the sliding sleeve so that when the sliding sleeve slides on the surface of the sliding rod, the sliding rod plays a limiting role on the sliding sleeve, ensuring that the sliding sleeve will not deviate from its position when sliding, thus improving the stability of the sliding sleeve.

[0014] 3. By setting up a rectangular sleeve, this utility model guides the two racks when they slide, ensuring that the two racks do not disengage from the gears during sliding and improving the racks' position from shifting during sliding.

Detailed Implementation

[0024] In the following description, embodiments of the sheet metal cutting device for metal electrical housings of the present invention will be described with reference to the accompanying drawings.

[0025] Figure 1-5This invention illustrates a sheet metal cutting device for a metal electrical housing according to an embodiment of the present invention. The device includes a sheet metal cutting machine 1, a fixed frame 2 fixedly connected to the top front side of the sheet metal cutting machine 1, a fixed plate 3 fixedly connected to the inner cavity of the fixed frame 2, a rectangular plate 4 fixedly connected to the central axis at the bottom of the fixed plate 3, four sliding rods 6 provided at the bottom of the fixed plate 3, and four mounting blocks 5 fixedly connected to the bottom of the fixed plate 3. The four mounting blocks 5 are fixedly connected to the sliding rods 6. Through the cooperation of the sliding rods 6 and the sliding sleeve 7, the sliding rods 6 limit the sliding sleeve 7 when it slides on the surface of the sliding rods 6, ensuring that the sliding sleeve 7 does not move during sliding. The offset position improves the sliding stability of the sliding sleeve 7. Sliding sleeves 7 are fixedly connected to the surface of the sliding rod 6. Two symmetrical connecting plates 8 are fixedly connected to the top of the four sliding sleeves 7. Connecting blocks 9 are fixedly connected to the central axis at the bottom of the two connecting plates 8. Rectangular blocks 10 are fixedly connected to the opposite side of the two connecting blocks 9. A rack 11 is fixedly connected to the rear side of the left rectangular block 10 and the front side of the right rectangular block 10. A rectangular sleeve 12 is fixedly connected to the front side of the left rectangular block 10 and the rear side of the right rectangular block 10. The inner cavity of the rectangular sleeve 12 is slidably connected to the rack 11. Through the arrangement of the rectangular sleeve 12, the two... When the rack 11 slides, the rectangular sleeve 12 guides the rack 11, ensuring that the two racks 11 do not disengage from the gear 15 during sliding, thus preventing the rack 11 from shifting position. The bottom of the rectangular plate 4 has a gear 15, and a disc 13 is fixedly connected to the left side of the bottom of the rectangular plate 4. A rotating rod 14 is rotatably connected to the central axis of the bottom of the disc 13. The rotating rod 14 is fixedly connected to the gear 15. Through the cooperation of the disc 13 and the rotating rod 14, when the gear 15 drives the rotating rod 14 to slide within the inner cavity of the disc 13, the disc 13 limits the movement of the rotating rod 14, ensuring that the rotating rod... 14 will not disengage from the limit of the disc 13 when rotating, which improves the stability of the rotation of the gear 15. Two racks 11 mesh with the gear 15. A cylinder 16 is fixedly installed on the top of the fixing plate 3. A fixing block 17 is fixedly connected to the output end of the cylinder 16. The fixing block 17 is fixedly connected to the left connecting plate 8. Multiple guide rollers 20 are provided in the inner cavity of the fixing frame 2. Side baffles 18 are fixedly connected to the bottom of the two connecting blocks 9 on opposite sides. Multiple connecting rods 19 are fixedly connected to the bottom of the two side baffles 18. The connecting rods 19 are rotatably connected to the guide rollers 20. A rectangular groove for the fixing block 17 to slide is opened on the left side of the top of the fixing plate 3.

[0026] Working Principle: When using this invention, the user places the board material on the conveyor belt of the board cutting machine 1, then activates the cylinder 16 on top of the fixed plate 3. The output end of the cylinder 16 drives the fixed block 17 to move, which in turn drives the connecting plate 8 on the left to move. Simultaneously, the two connecting plates 8 drive the sliding sleeve 7 to slide on the surface of the slide rod 6, causing the connecting plate 8 to drive the rack 11 on the left through the rectangular block 10. At the same time, the two racks 11 mesh with the gear 15, and the two racks 11 drive the gear... Wheel 15 rotates within the inner cavity of disc 13. Subsequently, two connecting plates 8 drive the bottom connecting block 9 to move towards each other. In turn, the two connecting blocks 9 drive the side baffle 18 to move, so that the side baffle 18 drives the guide roller 20 to move towards each other through the connecting rod 19. Since the guide roller 20 is rotatable, the plate does not restrict the movement of the plate when it moves at the position conveyed by the plate cutting machine 1. As a result, multiple guide rollers 20 clamp the plate of the metal electrical housing, ensuring that the plate of the metal electrical housing does not shift its position.

[0027] In summary, this sheet metal cutting device for metal electrical housings, by placing the sheet metal at the conveying position of the sheet metal cutting machine 1, and then through the cooperation of the connecting plate 8, rack 11, and gear 15, causes the two connecting blocks 9 to drive the guide rollers 20 to move in opposite directions in a rectangular shape, thereby clamping and guiding the sheet metal. Finally, the cutting direction of the sheet metal is horizontal, thus achieving the goal of using an opposing clamping and guiding structure. The centered guidance ensures that the sheet metal is always in an accurate position during the cutting process, strictly cutting according to the preset size and shape, with a stable relative position to the sheet metal, resulting in a smoother and flatter cut, reducing quality defects such as burrs and bevels, and effectively avoiding quality defects caused by sheet metal displacement, thereby improving the cutting quality of metal electrical housing sheet metal.
