Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet production equipment, in particular to a shearing device with a positioning structure for switch cabinet production and processing. Background Art

[0002] Switchgear, also known as complete switchgear or complete distribution device, is an electrical equipment mainly composed of circuit breakers. It means that the manufacturer assembles relevant high and low voltage electrical appliances (including control electrical appliances, protective electrical appliances, measuring electrical appliances) as well as busbars, current-carrying conductors, insulators, etc. in a closed or open metal cabinet according to the requirements of the primary electrical wiring diagram, as a device for receiving and distributing electrical energy in the power system.

[0003] During the processing of the switch cabinet, the metal sheet is generally cut to the required size by a shearing machine. The shearing machine uses one blade to make a reciprocating linear motion relative to another blade to shear the sheet. It uses the moving upper blade and the fixed lower blade, and adopts a reasonable blade gap to apply shearing force to metal sheets of various thicknesses, so that the sheet is broken and separated according to the required size.

[0004] When the metal sheet is cut by the shearing machine, a front support frame for supporting the sheet is provided at the front end thereof, and a positioning component for positioning the sheet is installed on the side of the front support frame. The positioning component can be adjusted according to the required size, so it can adapt to the processing requirements of switch cabinets of different sizes;

[0005] During actual operation, when the plate moves toward the shearing machine, the positioning block on the positioning assembly can be squeezed to rotate, so that the plate can smoothly pass through the top of the positioning assembly, and the positioning block on the positioning assembly will reset under its own weight, and then the plate will be pulled in reverse to fit the end face of the positioning block to achieve the positioning of the plate, and then the shearing machine can be used to cut one side of the plate. If the other side of the plate is to be cut, the plate needs to be rotated and adjusted, and since the positioning block on the positioning assembly will not shrink when the side is subjected to force, this operation needs to avoid the positioning block on the positioning assembly. Therefore, the plate needs to be lifted for rotation and adjustment, which is relatively laborious and inconvenient to operate. Based on this, a shearing device with a positioning structure is provided for switch cabinet production and processing. Utility Model Content

[0006] The purpose of the utility model is to provide a shearing device for production and processing of switch cabinets with a positioning structure in order to solve the problems in the above background.

[0015] When the arc surface of the positioning block is squeezed by the steel plate, the positioning block, the telescopic block and the rotating weight block rotate as a whole, so that the steel plate can move smoothly toward the direction of the shearing machine;

[0016] When the vertical surface of the positioning block is pressed by the steel plate, the positioning block remains stationary to achieve positioning of the steel plate.

[0019] The return spring is fixed between the bottom of the telescopic block and the bottom of the inner wall of the contraction groove;

[0020] Both sides of the positioning block are in arc structure. When the arc surface of the positioning block is squeezed by the steel plate, the positioning block and the telescopic block shrink downward to the inside of the shrinkage groove, so that the steel plate can rotate smoothly.

[0021] As a further solution of the utility model: the locking unit includes a threaded hole, a through hole, and a locking bolt;

[0022] The threaded hole is opened inside the T-shaped slider and passes through both sides of the T-shaped slider, the through hole passes through both sides of the U-shaped seat, the locking bolt passes through the through hole and the threaded hole from the outer side of the U-shaped seat and fits with the inner wall side of the T-shaped slide groove, and the locking bolt is threadedly connected to the threaded hole.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1 to 4 In the embodiment of the utility model, a shearing device for switch cabinet production and processing with a positioning structure comprises a shearing machine 1 and a fixed plate 2 fixed to the front end of the shearing machine 1, one end of the fixed plate 2 is fixedly connected to a front support frame 3, and the outer wall of the front support frame 3 is symmetrically provided with T-shaped slide grooves 4 on both sides, and a positioning component 5 is installed on the inner side of the T-shaped slide groove 4, and the positioning component 5 is used to provide positioning for the position of the steel plate 6;

[0034] The positioning assembly 5 includes a positioning unit, a contraction unit, and a locking unit;

[0035] The positioning unit is used to adjust the position along the track of the T-shaped slide groove 4 to achieve shear positioning of steel plates 6 of different sizes;

[0036] When the steel plate 6 is rotated to adjust the shear edge, the contraction unit is used to receive the side extrusion force from the steel plate 6 and contract and move so that the positioning unit does not interfere with the rotation of the steel plate 6;

[0037] The locking unit is used to achieve fixed locking of the positioning unit;

[0038] The positioning unit includes a T-shaped slider 501, a U-shaped seat 502, a rotating weight 503, a telescopic block 504, and a positioning block 505;

[0039] The T-shaped slider 501 is slidably connected to the inner side of the T-shaped slide groove 4, and the U-shaped seat 502 is attached to the outer side of the T-shaped slide groove 4 and connected to the T-shaped slider 501 through a locking unit;

[0040] The rotating weight 503 rotates on the inner side of the U-shaped seat 502 through the rotating shaft, the telescopic block 504 is slidably connected to the top of the rotating weight 503, the positioning block 505 is fixed to the top of the telescopic block 504 and the other protrudes above the U-shaped seat 502, the end surface of the positioning block 505 close to the shearing machine 1 is a vertical surface structure, and the end surface of the positioning block 505 away from the shearing machine 1 is an arc surface structure;

[0041] When the arc surface of the positioning block 505 is squeezed by the steel plate, the positioning block 505, the telescopic block 504, and the rotating weight block 503 rotate as a whole, so that the steel plate 6 can move smoothly toward the direction of the shearing machine 1;

[0042] When the vertical surface of the positioning block 505 is squeezed by the steel plate 6, the positioning block 505 remains stationary to achieve positioning of the steel plate 6;

[0043] The contraction unit includes a contraction slot 506 and a return spring 507;

[0044] The contraction groove 506 is provided at the top of the rotating weight block 503 and the telescopic block 504 is slidably connected to the inner side of the contraction groove 506;

[0045] The return spring 507 is fixed between the bottom of the telescopic block 504 and the bottom of the inner wall of the contraction groove 506;

[0046] The two sides of the positioning block 505 are in an arc structure. When the arc surface of the positioning block 505 is squeezed by the steel plate 6, the positioning block 505 and the telescopic block 504 shrink downward to the inside of the shrinkage groove 506, so that the steel plate 6 can rotate smoothly.

[0047] The locking unit includes a threaded hole 508, a through hole 509, and a locking bolt 510;

[0048] The threaded hole 508 is provided inside the T-shaped slider 501 and passes through both sides of the T-shaped slider 501. The through hole 509 passes through both sides of the U-shaped seat 502. The locking bolt 510 passes through the through hole 509 and the threaded hole 508 from the outer side of the U-shaped seat 502 and fits with the inner wall side of the T-shaped slide 4. The locking bolt 510 is threadedly connected with the threaded hole 508.

[0049] The top horizontal height of the telescopic block 504 is lower than the top horizontal height of the U-shaped seat 502 , and the upper surface of the U-shaped seat 502 matches the upper surface of the front support frame 3 and the processing table surface of the shearing machine 1 .

[0050] In this embodiment: it should be supplemented that: a scale is embedded in the upper surface of the front support frame 3, which is used to judge the distance between the vertical surface of the positioning block 505 and the blade of the shearing machine 1. This distance is the size left after the steel plate is cut;

[0051] When cutting the switch cabinet body sheet, first move the positioning component 5 to the required length and width positioning position of the sheet, and the operation is as follows:

[0052] First, loosen the locking bolt 510 so that the locking bolt 510 moves outward and separates from the inner wall side of the T-shaped slide 4. At this time, the positioning component 5 can be moved as a whole. The position of the scale corresponding to the vertical surface of the positioning block 505 can be used to determine whether the positioning component 5 is in place. When the scale position corresponding to the vertical surface of the positioning block 505 matches the required length or width of the plate, the locking bolt 510 can be tightened. In this way, the positioning component 5 is fixed at this position, and then other positioning components 5 can be adjusted accordingly.

[0053] After the positioning assembly 5 is installed, the steel plate 5 can be sheared. The operation steps are as follows:

[0054] The steel plate 5 is horizontally placed on the top of the front support frame 3 and pushed in the direction of the shearing machine 1. When the steel plate 5 is squeezed by the arc surface of the end face of the positioning block 505, the positioning block 505 is subjected to the squeezing force. At this time, the positioning block 505, the shrinking block 504, and the rotating weight block 503 rotate around the rotating axis of the rotating weight block 503. The positioning block 505 is rotated and stored in the U-shaped seat 502, so that the positioning block 505 will not interfere with the movement of the steel plate 5 in the direction of the shearing machine 1.

[0055] When the steel plate 5 passes through the top of this positioning block 505, the positioning block 505, the contraction block 504, and the rotating weight block 503 will rotate and reset under the action of the self-gravity of the rotating weight block 503, and the positioning block 505 will return to the state of protruding from the U-shaped seat 502. At this time, the steel plate 5 is pulled away from the shearing machine 1, so that the steel plate 5 is attached to the vertical surface of the positioning block 505. At this time, the bottom of the rotating weight block 503 is limited by the internal protrusion of the U-shaped seat 502 and cannot continue to rotate downward, and the squeezing force of the steel plate 5 on the positioning block 505 is perpendicular to the telescopic block 504, that is, the telescopic block 504 will not move downward and contract, and then the positioning block 505 can be kept still, thereby realizing the positioning of the steel plate 5, and then the shearing machine 1 can be started to shear the steel plate 5;

[0056] When the shearing of one side of the steel plate 5 is completed, the other side of the steel plate 5 can be sheared (it should be noted that the other side is perpendicular to the previous side, and the length and width shearing of the plate can be achieved by shearing these two sides). At this time, the steel plate 5 can be slightly pushed a distance in the direction of the shearing machine 1, so that there is a certain gap between the steel plate 5 and the positioning block 505, and then the steel plate 5 is rotated horizontally. During the rotation of the steel plate 5, it will contact and squeeze the side arc surface of the positioning block 505. When the side arc surface of the positioning block 505 is stressed, the positioning block 505 and the telescopic block 504 will move downward and shrink to the inside of the shrinkage groove 506 under the action of this squeezing force, and squeeze the return spring 509 to shrink. Finally, the top of the positioning block 505 is flush with the top of the U-shaped seat 502. In this way, the positioning block 505 will not interfere with the steel plate 5, so that the steel plate 5 can be smoothly rotated 90 degrees. At this time, the other side of the steel plate 5 is facing the shearing machine 1;

[0057] Then, according to the previous steps, the steel plate 5 is contacted and positioned with the positioning block 505 of another group. The overall operation is simple and convenient.

[0058] Through the cooperation of the above multiple parts, when the steel plate 5 is rotated and adjusted, there is no need to lift the steel plate 5, and the operation is more labor-saving.

[0059] Please refer to Figures 2 to 4 The rotating weight 503 is centered on the rotating shaft, and the overall weight of the part above the rotating shaft, the telescopic block 504, the positioning block 505, and the return spring 507 is less than the weight of the part below the rotating shaft.

[0060] In this embodiment: through this added structure, when the rotating weight block 503 loses the external squeezing force, the bottom of the rotating weight block 503 can automatically rotate downward under the action of its own gravity, thus providing a stable guarantee for the resetting of the positioning block 505.

[0061] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
