Technical Field
[0001] This utility model relates to the field of slitting shearing devices, and in particular to a movable slitting shearing device. Background Technology
[0002] A movable slitting shear is a type of mechanical device typically used in engineering, manufacturing, or other scenarios requiring precise cutting. Depending on its function, a movable slitting shear can precisely divide, slit, or cut materials.
[0003] Traditional movable slitting shears have limited adjustment options for the lower and upper cutter heads, making it difficult to move and adjust them at multiple angles and adapt them to different working conditions. This makes it difficult to ensure the accuracy of the movement of the lower and upper cutter heads, reducing the shearing effect and flexibility. Therefore, those skilled in the art have provided a movable slitting shear 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 movable slitting shearing device. Through a movable adjustment device, it achieves precise movement and multi-angle movement adjustment, thereby improving the shearing effect and shearing flexibility.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a movable splitting shearing device, comprising a support platform and a fixing frame, wherein the fixing frame is disposed at the center of the upper surface of the support platform, a support plate is provided at the front of the center side of the lower surface of the support platform, and a movable adjustment device is provided at the center side of the upper surface of the support plate.
[0006] The moving adjustment device includes a horizontal moving component and a forward and backward moving component. The horizontal moving component is located at the center of the upper surface of the support platform near both sides, and the forward and backward moving component is located at the center of the upper surface of the support platform near both sides.
[0007] The horizontal movement assembly includes a rotary motor, which is mounted on the upper surface of the support plate. The output end of the rotary motor passes through one side wall of the support platform and extends to one inner side wall of the support platform. First lead screws are provided at both the output end of the rotary motor and at one side of the upper center of the fixed frame. Connecting posts are provided at the ends of the two first lead screws, and second lead screws are provided at one end of each of the two connecting posts. The two second lead screws are rotatably connected to the support platform and one inner side wall of the fixed frame respectively via bearings. One end of the uppermost first lead screw passes through one inner side wall of the fixed frame and extends to one side of the fixed frame. At the wall, a transmission belt is sleeved on the outer side of the first lead screw and the output end of the rotary motor. Slide grooves are provided on both sides of the center of the upper surface of the support platform and the inner wall of the fixed frame. Slide rails are provided on both sides of the center of the upper surface of the support platform and the inner wall of the fixed frame. Moving blocks are provided at the center of the lower end face of the two slide rails at the bottom and at the center of the upper end face of the two slide rails at the top. The four moving blocks pass through the four slide grooves and lead to the interior of the support platform and the fixed frame, and are threadedly connected to the two first lead screws and the two second lead screws respectively. The two first lead screws and the two second lead screws are symmetrically arranged.
[0008] The above technical solution uses a rotary motor to drive the first lead screw to rotate, which in turn drives the connecting column and the second lead screw to rotate. A moving block is threadedly connected to the first and second lead screws, and a transmission belt drives the upper and lower first and second lead screws to rotate. This allows the slide rail to move horizontally, thereby enabling the lower and upper cutter heads to move horizontally. This ensures the accuracy of the movement of the lower and upper cutter heads, thus improving the shearing effect.
[0009] Furthermore, the forward and backward moving component includes multiple fixed blocks, which are respectively disposed at the front and rear positions of the center on both sides of the four slide rails. Each of the fixed blocks on one side is provided with a micro motor at the center of one side. Each of the four slide rails is provided with a rotating shaft at the front and rear positions of the center inside. The output ends of the multiple micro motors pass through the fixed block and the slide rail on one side in sequence and are connected to the end of the multiple rotary motors. Each of the four slide rails is provided with a roller at the front and rear positions of the center inside. Each of the multiple micro motors passes through the roller and is connected to an inner side wall of the slide rail.
[0010] The above technical solution uses a micro motor to drive a rotating shaft, which in turn drives a roller to roll. This ensures the roller moves smoothly within the slide rail, allowing the lower and upper cutter heads to move. This enables multi-angle adjustment, allowing for adjustments based on different working conditions and thus improving cutting flexibility.
[0011] Furthermore, four moving devices are arranged in a rectangular pattern at the center of the lower end face of the support platform. Each moving device includes a support leg, which is located at the lower end face of the support platform. A cylinder is located at the center of the inner wall of the support leg, a caster wheel is located at the center of the lower end face of the cylinder, a circular groove is located at the center of the lower end face of the support leg, and four shock-absorbing feet are arranged in a rectangular pattern at the center of the lower end face of the support leg.
[0012] With the above technical solution, when the device needs to be moved, the cylinder is activated to drive the casters to rise and fall, so that the casters pass through the circular groove and contact the ground. The staff pushes the device to move it. When the device reaches the target position, the cylinder retracts the casters into the support legs. The shock-absorbing feet then absorb and reduce the vibration and impact generated during the operation of the device, playing a buffering role and protecting the device and the ground from damage. This meets the needs of different application scenarios and improves practicality.
[0013] Furthermore, fixing plates are provided at the center of the upper surface of the support platform and at the center of the inner wall of the fixing frame. Lifting devices are provided at the center of the upper surface of the two lower fixing plates and the lower surface of the two upper fixing plates. The lifting devices include four hydraulic cylinders, which are respectively located at the upper and lower surfaces of the four fixing plates. Support blocks are provided at the output ends of the four hydraulic cylinders.
[0014] The above technical solution achieves height adjustment of the support block by controlling the extension and retraction of the hydraulic cylinder, thus enabling the height adjustment of the lower and upper cutter head devices.
[0015] Furthermore, four support columns are arranged in a rectangular pattern at the center of the upper surface of the two lower fixed plates and the lower surface of the two upper fixed plates. Each of the support columns has a lifting column at its center. The lifting columns pass through the center of the inner wall of the support columns and extend to the outside of the support columns, and are threadedly connected to the support columns. Each of the lifting columns has a drive motor at its center of the lower surface. Each of the support columns has a sliding groove at its center of the two inner side walls. Each of the drive motors has a slider at its center on both sides. The sliders are slidably connected to the sliding grooves.
[0016] Through the above technical solution, the sliding connection between the slider and the sliding groove allows the drive motor to move. The drive motor then drives the lifting column to rotate. The threaded connection between the lifting column and the support column, along with the start of the drive motor, enables the lifting column to work with the hydraulic cylinder to lift the support block, increasing the stability of the support block and thus achieving adaptive control of shear force.
[0017] Furthermore, a lower cutter head device is provided at the center of the upper end face of the two lower lifting devices at the lower end, and an upper cutter head device is provided at the center of the lower end face of the two upper lifting devices at the upper end.
[0018] The above technical solution, through the lower cutter head device and the upper cutter head device, enables the execution of the shearing work.
[0019] This utility model has the following beneficial effects:
[0020] 1. In this utility model, when the movable slitting shear is used, the horizontal moving component enables the slide rail to move horizontally, thereby enabling the lower and upper cutter heads to move horizontally. This ensures the accuracy of the movement of the lower and upper cutter heads, thus improving the shearing effect. Furthermore, the forward and backward moving component enables the lower and upper cutter heads to move, achieving multi-angle movement adjustment. This allows for adjustment according to different working conditions, thereby improving the shearing flexibility.
[0021] 2. In this utility model, the height of the support block is adjusted by controlling the extension and retraction of the hydraulic cylinder, which satisfies the height adjustment of the lower and upper cutter heads. The sliding connection between the slider and the sliding groove allows the drive motor to move. The drive motor then drives the lifting column to rotate. The threaded connection between the lifting column and the support column, and the start of the drive motor, enable the lifting column to cooperate with the hydraulic cylinder to lift the support block, increasing the stability of the support block and thus achieving adaptive control of shearing force.
[0022] 3. In this utility model, when the device needs to be moved, the cylinder is activated to drive the casters to rise and fall, so that the casters pass through the circular groove and contact the ground. The operator pushes the device to move it. When the device reaches the target position, the cylinder retracts the casters into the support legs. The shock-absorbing feet absorb and reduce the vibration and impact generated during the operation of the device, playing a buffering role and protecting the device and the ground from damage. This meets the needs of different application scenarios and improves practicality. Attached Figure Description

Each support column 602 has a lifting column 603 at its center. The lifting columns 603 pass through the center of the inner wall of each support column 602 and extend to the outside of the support column 602, and are threadedly connected to each support column 602. Each lifting column 603 has a drive motor 604 at its center of its lower end face. Each support column 602 has a sliding groove 605 at its center of both inner side walls.

The horizontal moving component includes a rotary motor 401, which is located on the upper surface of the support plate 3.

Each of the first lead screws 402 has a connecting post 403 at one end, and each of the two connecting posts 403 has a second lead screw 404 at one end. The two second lead screws 404 are rotatably connected to the inner sidewall of the support platform 1 and the fixed frame 2 respectively through bearings. One end of the first lead screw 402 at the upper end passes through the inner sidewall of the fixed frame 2 and extends to one side wall of the fixed frame 2. A transmission belt 412 is sleeved on the outer side of the output end of the first lead screw 402 and the rotary motor 401. Slide grooves 405 are provided on both sides of the center of the upper end face of the support platform 1 and the inner wall of the fixed frame 2.
[0036] Slide rails 406 are provided on both sides of the center of the upper end face of the support platform 1 and the inner wall of the fixed frame 2. Moving blocks 407 are provided at the center of the lower end face of the two lower slide rails 406 and the center of the upper end face of the two upper slide rails 406. The four moving blocks 407 pass through four sliding grooves 405 to the interior of the support platform 1 and the fixed frame 2, and are threadedly connected to the two first lead screws 402 and the two second lead screws 404 respectively. The two first lead screws 402 and the two second lead screws 404 are symmetrically arranged. The first lead screws 402 are driven by a rotary motor 401. The rotation, through the first lead screw 402, drives the connecting column 403 and the second lead screw 404 to rotate, and then through the threaded connection between the moving block 407 and the first lead screw 402 and the second lead screw 404, and through the transmission belt 412, can drive the upper and lower first lead screws 402 and the second lead screw 404 to rotate, so that it can drive the slide rail 406 to move horizontally, thereby driving the lower cutter head device 7 and the upper cutter head device 8 to move horizontally, thus ensuring the accuracy of the movement of the lower cutter head device 7 and the upper cutter head device 8, thereby improving the shearing effect.
[0037] The forward and backward moving assembly includes multiple fixed blocks 408, which are respectively disposed on both sides of four slide rails 406, near the front and rear of their centers. A micro motor 409 is located at the center of each of the fixed blocks 408 on one side. A rotating shaft 410 is located at the front and rear of the center of each of the four slide rails 406. The output ends of the micro motors 409 pass through the fixed blocks 408 and slide rails 406 on one side, extending into the interior of the slide rails 406, and are respectively fixedly connected to the ends of multiple rotary motors 401. The center of the four slide rails 406 is located near the front... Each part is equipped with a roller 411, and multiple micro motors 409 pass through the rollers 411 and extend to the inner side wall of the slide rail 406. The micro motors 409 drive the rotating shaft 410 to rotate, and the rotating shaft 410 drives the rollers 411 to roll, so that the rollers 411 can move smoothly inside the slide rail 406. This allows the lower cutter head device 7 and the upper cutter head device 8 to move, realizing multi-angle movement adjustment. This allows for adjustment according to different working conditions, thereby improving the cutting flexibility.
[0038] Working principle: When the movable slitting shear device needs to be moved, the cylinder 502 is activated to drive the casters 503 to rise and fall, so that the casters 503 pass through the circular groove 504 and contact the ground. The operator pushes the device to move it. When the device reaches the target position, the cylinder 502 retracts the casters 503 into the support legs 501. The shock-absorbing feet 505 absorb and reduce the vibration and impact generated during the operation of the device, playing a buffering role and protecting the device and the ground from damage. This meets the needs of different application scenarios and improves practicality.
[0039] Then, the rotary motor 401 drives the first lead screw 402 to rotate, which in turn drives the connecting column 403 and the second lead screw 404 to rotate. The moving block 407 is threadedly connected to the first lead screw 402 and the second lead screw 404, and the transmission belt 412 drives the upper and lower first lead screws 402 and the second lead screw 404 to rotate, which enables the slide rail 406 to move horizontally, thereby enabling the lower cutter head device 7 and the upper cutter head device 8 to move horizontally. This ensures the accuracy of the movement of the lower cutter head device 7 and the upper cutter head device 8, thus improving the shearing effect. The micro motor 409 drives the rotating shaft 410 to rotate, which in turn drives the roller 411 to roll, ensuring the smooth movement of the roller 411 inside the slide rail 406. This enables the movement of the lower cutter head device 7 and the upper cutter head device 8, realizing multi-angle movement adjustment, which can be adjusted according to different working conditions, thereby improving the shearing flexibility.
[0040] Next, by controlling the extension and retraction of the hydraulic cylinder 601, the height of the support block 607 is adjusted, enabling it to drive the lower cutter head device 7 and the upper cutter head device 8 to adjust their heights. Then, the sliding connection between the slider 606 and the sliding groove 605 allows the drive motor 604 to move. The drive motor 604 then drives the lifting column 603 to rotate. The lifting column 603 is threadedly connected to the support column 602. By starting the drive motor 604, the lifting column 603 can cooperate with the hydraulic cylinder 601 to lift and lower the support block 607, increasing the stability of the support block 607 and thus achieving adaptive control of the shearing force. Finally, the lower cutter head device 7 and the upper cutter head device 8 complete the shearing operation.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
