Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an anti-deviation shearing machine for manufacturing power distribution cabinet housings. Background Technology

[0002] Distribution cabinets are the final stage equipment in a power distribution system and are a general term for motor control centers. They are an indispensable piece of equipment in modern life. In the manufacturing of distribution cabinets, the outer shell of the distribution cabinet requires multiple metal plates of different sizes. At this time, a shearing machine is needed to cut the metal plates to form metal plates of different sizes. However, when using current shearing machines, the metal plates are prone to displacement, resulting in a high error rate when shearing metal plates.

[0003] Existing shearing machines, in order to prevent metal plate displacement during shearing, have a pressing rod driven by a cylinder or push rod at the front end of the shearing position to clamp the metal plate before cutting. However, this additional driving structure is electrically driven, which is prone to circuit failure and cannot properly press down and lock the metal plate, and also increases maintenance costs. Therefore, we propose an anti-deviation shearing machine for manufacturing electrical cabinet housings. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-deviation shearing machine for manufacturing power distribution cabinet housings. By uniformly fixing multiple vertical cylinders on the surface of the lifting plate on the side of the upper cutter, and connecting pressure rods that extend through the lifting plate to the bottom of the lifting plate, when the lifting plate drives the upper cutter to lower the height to cut the metal plate, the pressure rod contacts the metal plate before the upper cutter and presses down on the metal plate to lock it and prevent deviation. When the upper cutter continues to lower the height to cut, it effectively prevents the metal plate from shifting position and affecting the shearing quality, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-deviation shearing machine for manufacturing distribution cabinet housings, comprising a base and a support platform. The support platform is located on the side surface of the base. A lower cutting blade with an upper surface at the same height as the support platform is longitudinally installed on the base surface on the side of the support platform. An upper plate is supported above the base above the lower cutting blade by a support plate. Hydraulic cylinders are installed on both sides of the surface of the upper plate. A lifting plate is fixed at the bottom of the hydraulic cylinders and is parallel to the lower cutting blade. An upper cutting blade that is offset from and close to the lower cutting blade is longitudinally installed at the bottom of the lifting plate. A vertical cylinder located above the side of the support platform is fixed on the surface of the lifting plate on the side of the upper cutting blade. A pressure rod extending through to the bottom of the lifting plate is inserted inside the vertical cylinder. A sliding plate that can be slidably placed inside the vertical cylinder is fixed at the top of the pressure rod. A spring is placed between the sliding plate and the inside of the vertical cylinder.

[0006] By adopting the above technical solution, after the metal plate is placed on the support surface and adjusted to the correct position, the hydraulic cylinder drives the lifting plate to lower the height. The pressure rod will contact the metal plate before the upper cutter and press down to lock it. During shearing, the metal plate is prevented from shifting and affecting the shearing quality.

[0007] Optionally, a baffle is provided on the base surface on the side of the support, and the baffle is supported on the surface of the base by the bottom plate at its bottom.

[0008] By adopting the above technical solution, the baffle is supported on the base surface on the side of the support platform. The distance between the upper and lower cutters is adjusted to facilitate pushing the metal plate against the baffle and limiting the extension length, thereby achieving rapid positioning of the cutting length.

[0009] Optionally, multiple powerful magnets are uniformly embedded and fixed inside the base plate, and an anti-slip rubber pad is also attached and fixed to the bottom surface of the base plate.

[0010] By adopting the above technical solution, the base plate is adsorbed onto the surface of the base by a strong magnet, and the anti-slip rubber pad can make the base plate better anti-slip on the surface of the base.

[0011] Optionally, a rubber block is attached to the bottom surface of the pressure rod, and the diameter of the rubber block is the same as the bottom diameter of the pressure rod.

[0012] By adopting the above technical solution, the pressure bar presses against the surface of the metal plate through the rubber block, resulting in a better anti-slip effect when pressing against the metal plate.

[0013] Optionally, the lower cutter is bolted to the base surface via bolts on its side plate surface, and the upper cutter is mounted to the bottom surface of the lifting plate in the same manner.

[0014] By adopting the above technical solution, the upper and lower cutting blades can also be removed and replaced.

[0015] Optionally, a through-hole is provided on the surface of the lifting plate below the vertical cylinder, and the pressure rod passes through the through-hole to penetrate the lifting plate.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application involves uniformly fixing multiple vertical cylinders on the surface of the lifting plate on the side of the upper cutter, and connecting pressure rods that extend through to the bottom of the lifting plate. When the lifting plate drives the upper cutter to lower its height to cut the metal plate, the pressure rod contacts the metal plate before the upper cutter and presses down on the metal plate to lock it and prevent it from shifting. When the upper cutter continues to lower its height to cut, it effectively prevents the metal plate from shifting its position and affecting the quality of the cutting.

[0018] 2. The technical solution of this application sets up multiple vertical cylinders in conjunction with pressure rods to press and lock the metal plate, ensuring that the metal plate can be pressed down at all points to give it a better anti-slip effect. As the upper cutter lowers its height and the shearing force on the metal plate gradually increases, the spring is compressed more, thus the pressing and locking effect on the metal plate is also better.

[0019] 3. The technical solution of this application, by setting a baffle, can be magnetically attracted to a suitable position on the surface of the base by the potential magnet inside the base plate, which can be used to limit the length of the metal plate extending out, thereby achieving the purpose of limiting the cutting width of the metal plate.

[0025] Please see Figure 1-3This utility model provides a technical solution: an anti-deviation shearing machine for manufacturing power distribution cabinet housings, including a base 1 and a support 11. A lower cutter 4 is longitudinally arranged on the surface of the base 1 near the middle. The lower cutter 4 is installed and locked to the surface of the base 1 by bolts on the surface of its side plate. An upper plate 2 is supported on the base 1 above the lower cutter 4 by a support plate 21. Two hydraulic cylinders 22 are installed on both sides of the surface of the upper plate 2. The protruding ends of the two hydraulic cylinders 22 extend to the bottom of the upper plate 2. A lifting plate 3 is fixed at the bottom of the hydraulic cylinders 22, parallel to the lower cutter 4. An upper cutter 31 is longitudinally installed at the bottom of the lifting plate 3. The upper cutter 31 is installed on the bottom surface of the lifting plate 3 in the same way as the lower cutter 4. The upper cutter 31 and the lower cutter 4 are offset and close to each other. When the metal plate is placed between the upper cutter 31 and the lower cutter 4, and the upper cutter 31 is driven to lower the height, the metal plate can be cut by shearing action.

[0026] The aforementioned support 11 is located on the side of the base 1 on the side of the lower cutter 4, and the upper surface of the upper cutter 31 is at the same height as the upper surface of the support 11. When cutting the metal plate, the metal plate can be supported on the surface of the support 11, and the position to be cut can be placed exactly between the upper cutter 31 and the lower cutter 4, so that it can be cut smoothly.

[0027] A baffle 6 is placed on the surface of the base 1 on the side of the support 11. The baffle 6 is supported on the surface of the base 1 by the bottom plate 61 at its bottom. Multiple strong magnets 611 are evenly embedded and fixed inside the bottom plate 61. The bottom surface of the bottom plate 61 is also attached and fixed with an anti-slip rubber pad. In use, the baffle 6 is supported on the base 1 on the side of the support 11 by the bottom plate 61, and the distance between the baffle 6 and the cutting position of the lower cutter 4 and the upper cutter 31 is equal to the width of the metal plate to be cut. The position of the bottom plate 61 and the baffle 6 is locked by the strong magnets 611 adsorbing onto the surface of the base 1. The anti-slip rubber pad has a better anti-slip effect. In use, the metal plate is placed on the surface of the support 11 and pushed to the rear until it touches the side surface of the baffle 6 and is limited. The placement position of the metal plate can be quickly positioned.

[0028] To prevent displacement of the metal sheet during shearing by the upper cutter 31 and lower cutter 4, a vertical cylinder 5 is fixed to the surface of the lifting plate 3 on the side of the upper cutter 31. The vertical cylinder 5 is located above the side of the support 11, and a pressure rod 51 is inserted inside the vertical cylinder 5, extending downwards to the lower part of the lifting plate 3. A through-hole 32 is provided on the surface of the lifting plate 3 below the vertical cylinder 5, through which the pressure rod 51 passes. A sliding plate 512, which can be slidably placed inside the vertical cylinder 5, is fixed to the top of the pressure rod 51. A spring 52 is placed between the sliding plate 512 and the interior of the vertical cylinder 5, pressing against the surface of the sliding plate 512 and the interior of the vertical cylinder 5. When the lifting plate 3 lowers the upper cutter 31, and the upper cutter... Before the upper cutter 31 and the lower cutter 4 work to cut the metal plate, the bottom of the pressure rod 51 presses against the upper surface of the metal plate to prevent it from sliding. As the height of the upper cutter 31 decreases, the shearing force on the metal plate increases, making it easier for the metal plate to slide. At this time, the spring 52 is gradually compressed, which increases the downward pressure of the pressure rod 51 on the metal plate, resulting in a better anti-slip effect. When the upper cutter 31 and the lower cutter 4 work together to cut the metal plate, the metal plate can be prevented from shifting position, ensuring the shearing quality. The arrangement of multiple vertical cylinders 5 and multiple pressure rods 51 ensures that the metal plate can be pressed down at all points, giving it a better anti-slip effect.

[0029] A rubber block 511 is attached and fixed to the bottom surface of the pressure rod 51. The diameter of the rubber block 511 is the same as the bottom diameter of the pressure rod 51. The pressure rod 51 presses against the surface of the metal plate through the rubber block 511, which can play a better anti-slip role.

[0030] In use, the baffle 6 is supported by the base plate 61 and placed above the base 1 on the side of the support platform 11. The positions of the base plate 61 and the baffle 6 are locked by the strong magnet 611 adhering to the surface of the base 1. The distance between the baffle 6 and the upper cutter 31 and the lower cutter 4 is adjusted to limit the width of the metal plate being cut. The hydraulic cylinder 22 is connected to the hydraulic workstation, so that the lifting and lowering of multiple hydraulic cylinders 22 can be controlled synchronously. First, the metal plate is placed on the surface of the support platform 11 and pushed to the rear until it touches the side surface of the baffle 6 and is limited. Then, the two hydraulic cylinders 22 are controlled to synchronously drive the lifting plate 3 to lower the upper cutter 31. Before the upper cutter 31 and the lower cutter 4 work to cut the metal plate, the bottom of the pressure rod 51 is pressed against the upper surface of the metal plate by the rubber block 511 to prevent it from sliding. As the height of the upper cutter 31 decreases, the anti-slip effect of pressing and locking the metal plate will be better. When the upper cutter 31 and the lower cutter 4 work together to cut the metal plate, the metal plate can be prevented from shifting position, ensuring the cutting quality. After the cutting is completed, when the lifting plate 3 is driven to rise, the upper cutter 31 rises and the bottom of the pressure rod 51 no longer presses against the surface of the metal plate, and then the metal plate can continue to be pushed to perform the cutting work.
