Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an adjustment device that can automatically adjust the blade gap of a shearing machine. Background Technology

[0002] In the use of shearing machines, the adjustment of the blade gap is crucial. On the one hand, the blade will gradually wear down during the shearing process, affecting the shearing accuracy and quality. On the other hand, it is necessary to control production costs. The cost of the blade is too high, and it is not possible to replace the blade frequently. The blade can still be used after it is worn out, but the blade gap needs to be controlled. This has led to the development of a device that can adjust the blade gap.

[0003] Traditional blade gap adjustment methods are mostly manual, which is not only inefficient but also difficult to guarantee in terms of adjustment accuracy. When the blade gap is too large, it is easy to cause the steel coil to not be cut and the cross-section to curl. When the blade gap is too small, it will significantly increase the unit shear resistance, intensify the friction between the blade and the material, and cause the blade temperature to rise sharply, accelerating blade wear. At the same time, local stress concentration may cause blade chipping, which can easily affect the shearing quality. Moreover, with the increase in the degree of production automation, the demand for automatic blade gap adjustment of shearing machines is increasing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adjustment device that can automatically adjust the blade gap of a shearing machine. The device includes a servo motor fixed to the shearing machine body, a transmission device connected to the output end of the servo motor, and a wedge fixedly connected to the output end of the transmission device. The end of the wedge furthest from the transmission device is inserted between the inner wall of the shearing machine body and a fixed blade. The side of the wedge closest to the fixed blade is inclined and gradually thickens from the end furthest from the transmission device to the end closest to it. The fixed blade is slidably connected to the shearing machine body, and the movable blade is located on the side of the fixed blade furthest from the wedge.

[0005] As a preferred embodiment of the present invention: the servo motor is fixedly mounted on the motor base, and the motor base is fixedly connected to the shearing machine body.

[0006] As a preferred embodiment of the present invention, it further includes a rear cover and an end cover, which are fixedly connected and enclose the transmission device.

[0007] As a preferred technical solution of the present invention: a limiting block is fixedly installed at the output end of the transmission device, the limiting block is wrapped by the rear cover and the end cover and is limited within the rear cover and the end cover, and the wedge is fixedly installed on the limiting block on the side away from the transmission device.

[0008] As a preferred embodiment of the present invention: a connector is fixedly installed on the side of the limiting block away from the transmission device, the diameter of the connector is smaller than the diameter of the limiting block and penetrates the rear cover and the end cover, and the wedge is fixedly installed on the side of the connector away from the limiting block.

[0009] As a preferred embodiment of the present invention: a shaft end baffle is fixedly installed on the side of the joint away from the limiting block, and the wedge is fixedly installed on the side of the shaft end baffle away from the joint.

[0010] As a preferred embodiment of the present invention: the output end of the servo motor is connected to a coupling, and the output end of the coupling is connected to the input end of the transmission device.

[0011] As a preferred embodiment of the present invention, the transmission device is a screw jack.

[0012] As a preferred embodiment of the present invention: the transmission device includes a fixed mounting box, a plane bearing is fixedly mounted inside the mounting box, a sub-bevel gear is fixedly mounted on the plane bearing, the output end of the servo motor is connected to the shaft, a female bevel gear that meshes with the sub-bevel gear is fixedly sleeved on the shaft, a threaded rod is threadedly connected to the inner wall of the sub-bevel gear, and one end of the threaded rod is fixedly connected to the wedge.

[0013] As a preferred embodiment of the present invention, the cross-section of the wedge is rectangular.

[0014] This utility model has the following beneficial effects: By setting a servo motor, the servo motor drives the wedge to move when it rotates, so that the inclined surface on the wedge abuts against the fixed blade, driving the fixed blade to move closer to the moving blade, reducing the blade gap between the moving blade and the fixed blade. This replaces manual adjustment, improves efficiency, and has higher adjustment precision, thus improving the shearing quality. The blade gap can be adjusted according to the different materials and thicknesses of the steel coil, keeping the blade gap within a reasonable range that matches the steel coil.

[0019] The principles and features of this utility model are described below. The embodiments given are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0020] It should be noted that when a part or component is considered to be "connected to," "located on," or "assembled" to another part or component, it can be directly mounted on the other part or component, or it may be located in an intermediate part or component. The terms "left," "right," "upper," "lower," and similar expressions used in this document are for illustrative purposes only.

[0021] Example 1, as Figure 1-3 As shown, an adjustment device for automatically adjusting the blade gap of a shearing machine includes a servo motor 10 fixed on the shearing machine body 12. The output end of the servo motor 10 is connected to a transmission device 7. The output end of the transmission device 7 is fixedly connected to a wedge 1. The end of the wedge 1 away from the transmission device 7 is inserted between the inner wall of the shearing machine body 12 and the fixed blade 14. The side of the wedge 1 near the fixed blade 14 is inclined and gradually thickens from the end away from the transmission device 7 to the end near the transmission device 7. The fixed blade 14 is slidably connected to the shearing machine body 12, and the movable blade 13 is located on the side of the fixed blade 14 away from the wedge 1.

[0022] The servo motor 10 converts the rotational power into translational power output through the transmission device 7, driving the thicker part of the wedge 1 to move into the gap between the inner wall of the shearing machine body 12 and the fixed blade 14, thereby driving the fixed blade 14 to move closer to the movable blade 13.

[0023] In this embodiment, the transmission device 7 is a screw jack.

[0024] The movable blade 13 is rotatably connected to the shearing machine body 12. A hydraulic rod is rotatably connected to the shearing machine body 12, and the hydraulic rod is rotatably connected to the movable blade 13 to drive the movable blade 13 to rotate and perform the shearing action during extension and retraction. It is worth noting that no matter what angle the movable blade 13 rotates to, a portion of the movable blade 13 is always located on the side of the fixed blade 14. That is, the fixed blade 14 can only move to contact the side wall of the movable blade 13 at most, and cannot move below the movable blade 13, to prevent the blade gap formed by the movable blade 13 and the fixed blade 14 from being negative, thus preventing shearing from being impossible.

[0025] The output end of the servo motor 10 is connected to a coupling 9, and the output end of the coupling 9 is connected to the input end of the transmission device 7. Specifically, the output end of the coupling 9 is connected to the input shaft of the screw jack to drive the input shaft of the screw jack to rotate, thereby causing the output end of the screw jack to translate.

[0026] Example 2, as Figure 1-3 As shown, this embodiment is an improvement on embodiment 1, and also includes a rear cover 6 and an end cover 8. The rear cover 6 and the end cover 8 are fixedly connected to enclose the transmission device 7. The rear cover 6 and the end cover 8 are fixedly connected by several pins 3. The end of the transmission device 7 away from the wedge 1 passes through the rear cover 6 and the end cover 8. A limiting block 5 is fixedly installed at the output end of the transmission device 7. The limiting block 5 is enclosed and limited within the rear cover 6 and the end cover 8. That is, the transmission device 7 reaches its maximum translational distance when it drives the limiting block 5 to contact the inner wall of the rear cover 6 and the end cover 8. The limiting block 5 prevents the output shaft of the transmission device 7 from continuing to translate towards the wedge 1 by abutting against the rear cover 6 and the end cover 8. The wedge 1 is fixedly installed on the limiting block 5 on the side away from the transmission device 7. A connector 4 is fixedly installed on one side away from the transmission device 7. The diameter of the connector 4 is smaller than the diameter of the limiting block 5 and passes through the rear cover 6 and the end cover 8, so that the connector 4 can pass through the rear cover 6 and the end cover 8, but the limiting block 5 cannot pass through the rear cover 6 and the end cover 8. The wedge 1 is fixedly installed on the side of the connector 4 away from the limiting block 5. A shaft end baffle 2 is fixedly installed on the side of the connector 4 away from the limiting block 5. The wedge 1 is fixedly installed on the side of the shaft end baffle 2 away from the connector 4. The diameter of the shaft end baffle 2 is larger than the diameter of the connector 4 to increase the contact area with the wedge 1 and prevent the connector 4 from directly contacting the wedge 1 and causing excessive pressure to squeeze the wedge 1 indented. At the same time, the shaft end baffle 2 can also prevent foreign objects from entering the interior of the rear cover 6 and the end cover 8 through the gap formed between the connector 4 and the rear cover 6 and the end cover 8.

[0027] Embodiment 2 can make the overall structure more stable and reliable, while preventing the output shaft of the transmission device 7 from translating excessively. This is because when the thickest part of the wedge 1 is inserted between the shearing machine body 12 and the fixed blade 14, the output shaft of the transmission device 7 cannot adjust the blade gap between the movable blade 13 and the fixed blade 14 even if it continues to translate.

[0028] Example 3, as Figure 1-3 As shown, the difference between this embodiment and Embodiment 1 or Embodiment 2 is that the transmission device 7 includes a fixed mounting box 701, a plane bearing 702 is fixedly installed inside the mounting box 701, a sub-bevel gear 703 is fixedly installed on the plane bearing 702, and the output end of the servo motor 10 is connected to the shaft 705 for transmission. Specifically, the two ends of the coupling 9 are respectively connected to the output shaft of the servo motor 10 and the shaft 705 to realize the transmission connection between the shaft 705 and the servo motor 10. A female bevel gear 706 that meshes with the sub-bevel gear 703 is fixedly sleeved on the shaft 705. The sub-bevel gear 703 and the female bevel gear 706 form a 90-degree angle. A threaded rod 704 is threadedly connected to the inner wall of the sub-bevel gear 703, and one end of the threaded rod 704 is fixedly connected to the wedge 1.

[0029] The servo motor 10 drives the shaft 705 to rotate the female bevel gear 706, which in turn drives the male bevel gear 703 to rotate. The male bevel gear 703 is threadedly connected to the threaded rod 704, so that when the male bevel gear 703 rotates, the rotational force is converted into a translational force to drive the threaded rod 704 to move, thereby driving the wedge 1 to move, achieving the same function as the screw jack.

[0030] Based on Embodiment 2, the threaded rod 704 is fixedly connected to the limiting block 5, and the end of the threaded rod 704 away from the limiting block 5 passes through the rear cover 6 and the end cover 8. The mounting box 701 is fixedly installed on the inner wall of the rear cover 6 and / or the end cover 8.

[0031] It is worth noting that the cross-section of the wedge 1 is rectangular, so that after the wedge 1 is inserted into the gap between the shearing machine body 12 and the fixed blade 14, the wedge 1 cannot rotate. That is, when the sub-conical gear 703 drives the threaded rod 704 to rotate, because the wedge 1 is stuck in the gap between the shearing machine body 12 and the fixed blade 14, and the cross-section of the wedge 1 is rectangular, the wedge 1 prevents the wedge 1 from rotating by contacting the side wall of the shearing machine body 12 and the fixed blade 14, thereby preventing the threaded rod 704 from rotating, so as to achieve the purpose of the sub-conical gear 703 rotating to drive the threaded rod 704 to translate through the thread.

[0032] The above-mentioned adjustment device, which can automatically adjust the blade gap of the shearing machine, can be further optimized and / or improved according to actual needs: The servo motor 10 is fixedly mounted on the motor base 11, and the motor base 11 is fixedly connected to the shearing machine body 12, making the installation of the servo motor 10 more stable and reliable.

[0033] In summary: By setting up a servo motor 10, the servo motor 10 drives the wedge 1 to move when it rotates, so that the inclined surface on the wedge 1 abuts against the fixed blade 14, driving the fixed blade 14 to move closer to the movable blade 13, reducing the blade gap between the movable blade 13 and the fixed blade 14. This replaces manual adjustment, improves efficiency, and has higher adjustment accuracy, thus improving the shearing quality. The blade gap can be adjusted according to the different materials and thicknesses of the steel coil, keeping the blade gap within a reasonable range that matches the steel coil.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Anyone skilled in the art can smoothly implement this utility model according to the accompanying drawings and the above description. However, any modifications, alterations, or equivalent changes made by those skilled in the art without departing from the scope of the technical solution of this utility model using the disclosed technical content are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or evolutions made to the above embodiments based on the essential technology of this utility model are still within the protection scope of the technical solution of this utility model.
