Description

Technical Field

[0001] This utility model relates to the field of disc shears, and in particular to a disc shearing edge adjustment mechanism. Background Technology

[0002] The disc shearing edge adjustment mechanism is a commonly used piece of equipment in the metal processing industry. It is mainly used to cut metal sheets into the required size and shape. The disc shear mainly consists of a frame, transmission system, cutter shaft, blades, adjustment mechanism and safety device. The blades are usually installed in pairs, one above the other, and cut by rotating.

[0003] The existing disc shearing edge adjustment mechanism is difficult to adjust the position accurately, which requires a lot of time to reposition and adjust when processing materials of different specifications, affecting production efficiency. It cannot adapt well to the shearing requirements of materials of different thicknesses and is prone to material displacement during the shearing process, affecting the shearing accuracy. Therefore, those skilled in the art have provided a disc shearing edge adjustment mechanism to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a disc shearing edge adjustment mechanism. Through a moving structure and a lifting structure, the horizontal position of the mounting plate can be precisely adjusted. The lifting structure uses a motor to drive a lead screw to move the slider up and down in the groove, adjusting the height of the shearing structure. This mechanism can flexibly adapt to materials of different sizes and thicknesses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a disc shearing edge adjustment mechanism, comprising a base, wherein movable structures are provided on both sides of the center of the upper end surface of the base, near the front and near the rear.

[0006] The four movable structures include four first sliding grooves, four first motors, and two sliding grooves. The four first sliding grooves are respectively located at the front and rear sides of the upper end face of the base. The four first motors are respectively located at the front and rear sides of the upper end of the two side walls of the base. The output ends of the four first motors pass through the two side walls of the base and the one side wall of the four first sliding grooves in sequence and lead into the interior of the four first sliding grooves. Each end is fixedly connected to a first lead screw. The outer side wall of each of the four first lead screws is threaded with a first slider. The two sliding grooves are respectively located at the center of the upper end face of the base on both sides. Each of the two sliding grooves has a sliding plate at the center of the upper end face on one side.

[0007] Mounting plates are provided at the center of the upper end face of the two first sliders on one side and the two first sliders on the other side. Shearing structures are provided at the upper and lower center of the side wall of the two lifting structures. The upper end face of the base is provided with four clamping structures arranged in a rectangle.

[0008] The above technical solution achieves precise adjustment of the horizontal position of the mounting plate through the moving structure and the lifting structure. The lifting structure uses a motor to drive the lead screw to move the slider up and down in the slide groove, adjusting the height of the shearing structure, which can flexibly adapt to materials of different sizes and thicknesses.

[0009] Furthermore, the two lifting structures include two first frames, which are respectively located at the center of the upper surface of the two mounting plates. A second slide groove is provided at the center of one side wall of each of the two first frames. A connecting block is provided at the center of the interior of each of the two second slide grooves. A second motor is provided at one side of the center of the upper surface of each of the two first frames. The output ends of the two second motors pass through the upper surface of the two first frames and the upper surface of the two second slide grooves respectively and are connected to the interior of the two second slide grooves. A second lead screw is fixedly connected to each end of the motor. One end of each of the two second lead screws passes through the upper surface of the two connecting blocks and is connected to the lower surface of the two connecting blocks. A third lead screw is fixedly connected to each end of the motor. A second slider is threaded onto the outer wall of each of the two second lead screws and the two third lead screws.

[0010] The above technical solution involves starting the second motor, which drives the second lead screw to rotate. The second lead screw then drives the third lead screw to rotate, which in turn drives the second slider to move. When the second motor rotates, the two second sliders move up or down simultaneously within the second slide groove. The second sliders drive the shearing structure to move up and down, adjusting the height of the shearing structure to adapt to the thickness of the material to be sheared.

[0011] Furthermore, the two second lead screws and the two third lead screws are all configured with opposite threads;

[0012] The above technical solutions reduce the complexity and cost of the equipment, while also improving the accuracy and speed of lifting.

[0013] Furthermore, the four clamping structures include four electric telescopic rods and a rubber pad. The four electric telescopic rods are arranged in a rectangular pattern on the upper surface of the base. The rubber pad is located at the center of the upper surface of the base. The output ends of the four electric telescopic rods and the upper surface of the rubber pad are each provided with a placement platform. Multiple bearings are arranged in a front-to-back pattern at the lower center of the two side walls of the upper placement platform and at the upper center of the two side walls of the lower placement platform. Multiple rolling wheels are arranged in a front-to-back pattern at the center of the interior of the two placement platforms. The multiple rolling wheels are rotatably connected to the multiple bearings.

[0014] The above technical solution involves placing the material to be cut on a lower platform, adjusting the height of the upper platform using an electric telescopic rod, and using a rubber pad on the lower platform for cushioning and protection. Multiple rollers on the two platforms rotate under the support of bearings, facilitating the movement and adjustment of the material and placing it in a suitable cutting position.

[0015] Furthermore, the four first sliders are slidably connected inside the four first slide grooves, and the two slide plates are slidably connected inside the two slide grooves.

[0016] The above technical solutions reduce frictional resistance during movement, improve the accuracy and efficiency of movement, and also reduce equipment wear and failure rate.

[0017] Furthermore, the shearing structure includes four third motors, which are respectively located at the upper and lower positions of the center of one side wall of the two lifting structures. Each of the four third motors has a first clamping wheel at its output end. Each first clamping wheel has a shearing wheel on its outer side wall, and each of the two shearing wheels has a second clamping wheel on its outer side wall. The two first clamping wheels and the two clamping wheels are fixed together.

[0018] Furthermore, each of the second clamping wheels has four bolts on one side wall, the bolts passing through the second clamping wheel, the two shearing wheels, and the first clamping wheel in sequence;

[0019] With the above technical solution, when the shearing wheel needs to be replaced or repaired, simply loosen the nut to disassemble each component for replacement or repair, thus improving the maintainability of the equipment.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the disc shearing edge adjustment mechanism achieves precise adjustment of the horizontal position of the mounting plate through a moving structure and a lifting structure. The lifting structure uses a motor to drive the lead screw to move the slider up and down in the groove, adjusting the height of the shearing structure, which can flexibly adapt to materials of different sizes and thicknesses.

[0022] 2. In this utility model, the height of the placement platform can be adjusted by combining the electric telescopic rod and the rubber pad. The rubber pad plays a buffering and protective role. The rolling wheels supported by bearings inside the placement platform facilitate the movement and adjustment of materials, thereby improving clamping stability and work efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 This utility model provides an embodiment of a disc shearing edge adjustment mechanism, comprising a base 1. Movable structures 2 are provided on both sides of the center of the upper surface of the base 1, near the front and rear. Mounting plates 3 are provided at the center of the upper surfaces of two first sliders 204 on one side and two first sliders 204 on the other side. Lifting structures 4 are provided at the center of the upper surfaces of the two mounting plates 3. Four clamping structures 6 are arranged in a rectangular pattern on the upper surface of the base 1. The horizontal position of the lifting structures 4 on the mounting plates 3 is adjusted by the movable structures 2 to align with the material to be sheared at different positions. The mounting plates 3 provide a mounting base for the lifting structures 4, ensuring the stability of the lifting structures 4 during movement. The lifting structures 4 drive the shearing structure 5 to move up and down, adjusting the shearing height to accommodate materials of different thicknesses. After the shearing structure 5 reaches the appropriate position under the adjustment of the lifting structures 4, it performs the shearing operation on the material. The four clamping structures 6 on the base 1 clamp and fix the material, ensuring its stability during the shearing process.

[0031] The four movable structures 2 include four first sliding grooves 201, four first motors 202, and two sliding grooves 205. The four first sliding grooves 201 are respectively located at the front and rear sides of the upper end face of the base 1. The four first motors 202 are respectively located at the front and rear sides of the upper end of the two side walls of the base 1. The output ends of the four first motors 202 pass through the two side walls of the base 1 and one side wall of the four first sliding grooves 201, and are connected to the interior of the four first sliding grooves 201. Each end is fixedly connected to a first lead screw 203. The outer walls of the four first lead screws 203 are threaded with first sliders 204. The two sliding grooves 205 are respectively located at the center of the upper end face of the base 1 on both sides. The center of the upper end face of the two sliding grooves 205 is close to one side. Each side is equipped with a sliding plate 206, and four first sliders 204 are slidably connected inside four first slide grooves 201. The first motor 202 drives the first lead screw 203 to rotate, causing the first sliders 204 to slide in the first slide grooves 201. Two first sliders 204 and two first sliders 204 on the other side drive two mounting plates 3 to move, thereby adjusting the horizontal position of the lifting structure 4 and the shearing structure 5 on the mounting plate 3 so that they can be aligned with the material to be sheared at different positions. The two sliding plates 206 are slidably connected inside two slide grooves 205, which reduces the frictional resistance during movement, improves the accuracy and efficiency of movement, and also reduces the wear and failure rate of the equipment.

[0032] The two lifting structures 4 include two first frames 401, which are respectively located at the center of the upper end face of the two mounting plates 3. Each of the two first frames 401 has a second slide groove 402 at the center of one side wall. Each of the two second slide grooves 402 has a connecting block 406 at its center. Each of the two first frames 401 has a second motor 403 located near one side of its upper end face. The output ends of the two second motors 403 pass through the upper end face of the two first frames 401 and the upper end face of the two second slide grooves 402, respectively, and are connected to the interior of the two second slide grooves 402. Each end of the second motor 403 is fixedly connected to a second lead screw 404. One end of each second lead screw 404 passes through the upper end face of the two connecting blocks 406, respectively, and is connected to the lower end face of the two connecting blocks 406. Each end of the second lead screw 404 is fixedly connected to a third lead screw 404. 5. The outer walls of the two second lead screws 404 and the third lead screw 405 are all threaded with second sliders 407. By starting the second motor 403, the second lead screws 404 are driven to rotate, which in turn drives the third lead screw 405 to rotate. The second lead screws 404 and the third lead screw 405 drive the second sliders 407 to move. When the second motor 403 rotates, the two second sliders 407 move up or down simultaneously in the second slide groove 402. The second sliders 407 drive the shearing structure 5 to move up and down, adjusting the height of the shearing structure 5 to adapt to the thickness of the material to be sheared. The two second lead screws 404 and the two third lead screws 405 are all threaded in opposite directions, which reduces the complexity and cost of the equipment, while also improving the accuracy and speed of lifting.

[0033] The four shearing structures 5 include four third motors 501, which are respectively located at the upper and lower positions of the center of one side wall of the two lifting structures 4. Each of the four third motors 501 has a first clamping wheel 502 at its output end. Two shearing wheels 504 are located on the outer wall of each of the four first clamping wheels 502. A second clamping wheel 505 is located on the side wall of each of the two shearing wheels 504. Four bolts 503 are arranged in a ring on the outer wall of each second clamping wheel 505. The second clamping wheels 505 are connected to the shearing structure 505 by the bolts 503. The first clamping wheel 502 is fixed to ensure the stability of the shearing wheel 504. The first clamping wheel 502 is driven to rotate by starting the third motor 501. The two shearing wheels 504 are driven by the third motor 501 to shear the material. One end of the bolt 503 passes through the second clamping wheel 505, the shearing wheel 504 and the first clamping wheel 502 in sequence. When the shearing wheel 504 needs to be replaced or repaired, the nuts can be loosened to disassemble each part for replacement or repair, which improves the maintainability of the equipment.

[0034] like Figure 1 , 2 As shown, the four clamping structures 6 include four electric telescopic rods 601 and rubber pads 603. The four electric telescopic rods 601 are arranged in a rectangular pattern on the upper surface of the base 1. The rubber pads 603 are located at the center of the upper surface of the base 1. Placement platforms 602 are provided at the output ends of the four electric telescopic rods 601 and on the upper surface of the rubber pads 603. Multiple bearings 604 are arranged in a front-to-back pattern at the lower center of the side walls of the upper placement platform 602 and at the upper center of the side walls of the lower placement platform 602. The centers of the two placement platforms 602 are... Multiple rollers 605 are arranged in a front-to-back configuration, and each roller 605 is rotatably connected to multiple bearings 604. The material to be cut is placed on the lower placement platform 602. The height of the upper placement platform 602 is adjusted by an electric telescopic rod 601. The rubber pads 603 on the lower placement platform 602 provide cushioning and protection. The multiple rollers 605 on the two placement platforms 602 rotate under the support of the bearings 604, which facilitates the movement and adjustment of the material, so that the material is in a suitable cutting position.

[0035] Working principle: The material to be cut is placed on the lower placement platform 602. The height of the upper placement platform 602 is adjusted by the electric telescopic rod 601. The rubber pad 603 on the lower placement platform 602 provides cushioning and protection. Multiple rolling wheels 605 on the two placement platforms 602 rotate under the support of bearings 604, facilitating the movement and adjustment of the material's position to ensure it is in a suitable cutting position. The first motor 202 drives the first lead screw 203 to rotate, causing the first slider 204 to slide within the first groove 201. The two first sliders 204, along with two other first sliders 204 on the opposite side, respectively drive... The two mounting plates 3 move, thereby adjusting the horizontal position of the lifting structure 4 and the shearing structure 5 on the mounting plates 3 so that they can be aligned with the material to be sheared at different positions. By starting the second motor 403, the second lead screw 404 is driven to rotate, and the second lead screw 404 in turn drives the third lead screw 405 to rotate. The second lead screw 404 and the third lead screw 405 drive the second slider 407 to move. When the second motor 403 rotates, the two second sliders 407 move up or down simultaneously in the second slide groove 402. The second sliders 407 drive the shearing structure 5 to move up and down, adjusting the height of the shearing structure 5 to adapt to the thickness of the material to be sheared.
