Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic guillotine shearing machines, specifically to a plate positioning device for hydraulic guillotine shearing machines. Background Technology

[0002] Hydraulic guillotine shearing machines are a common type of metal processing equipment, mainly used for shearing metal sheets. To ensure the precision and accuracy of the cutting, a sheet positioning device is often required to ensure the stability of the sheet during shearing.

[0003] In response, Chinese patent application number CN202421259626.X discloses a plate positioning device for a hydraulic guillotine shearing machine. The device includes a shearing machine, a support frame, and plates. A base frame is installed at the bottom of the shearing machine. A cylinder is installed inside the support frame, and a top plate is mounted on the cylinder. An electric telescopic rod is installed inside the support frame, and a crossbar is mounted on the electric telescopic rod. A mounting platform is installed at the top of the support frame, and a motor is mounted on the mounting platform. A drive roller is mounted on the support frame. This invention, through the cylinder, top plate, electric telescopic rod, and drive roller, allows for the storage and continuous output of plates to the shearing machine, eliminating the need for continuous manual monitoring of the plate's processing progress and manual placement of plates throughout the process, thus reducing labor costs. Through the support frame, cylinder, electric telescopic rod, and limiting mechanism, the plate's positioning within the support frame is aligned with the position of the shearing machine, achieving a pre-positioning effect. Direct conveying allows the plate to reach the accurate processing position within the shearing machine, reducing operational steps and ensuring processing efficiency.

[0004] The device positions the sheet metal by using a clamping component and a top spring. However, the clamping component is set at an angle, and the sheet metal needs to move horizontally to squeeze the clamping component when positioning it. There is a certain amount of friction between the two, which will scratch the surface of the sheet metal. This makes it unsuitable for some sheets metal with patterns on the surface, which limits the use of the device.

[0005] Therefore, in order to solve the above problems, a plate positioning device for a hydraulic guillotine shearing machine is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a plate positioning device for a hydraulic guillotine shearing machine, in order to solve the problem mentioned in the background art that the clamping parts of the existing hydraulic guillotine shearing machine are set at an angle. When positioning the plate, the plate needs to move horizontally to squeeze the clamping parts. There is a certain friction between the two, which will scratch the surface of the plate. This makes it unsuitable for some plates with patterns on the surface, thus limiting the use of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a plate positioning device for a hydraulic guillotine shearing machine, comprising: a machine body, wherein a shearing seat is installed at the front end of the machine body;

[0008] The top surface of the shearing seat is equipped with a positioning structure, which includes a fixing plate. The fixing plate is fixedly installed on both sides of the top surface of the shearing seat. A rotating cylinder is movably installed on the inner side of the fixing plate through a bearing. A slot is opened at the rear end of the top surface of the fixing plate. A connecting groove is opened on the front side wall of the fixing plate. A connecting block is movably installed on the inner side of the connecting groove through a bearing. A coil spring is fixedly connected to the inside of the surface of the connecting block. A movable arm is fixedly connected to the end of the connecting block. A pressure cylinder is movably installed at the rear end of the movable arm through a bearing. A soft-padded grip is fixedly connected to the front end of the movable arm.

[0009] A support structure is installed on the positioning structure. The support structure includes a guide rod, which is fixedly connected to the front end of two sets of fixing plates. A support frame is slidably installed on the guide rod.

[0010] Preferably, the top surfaces of the shearing seat, rotating cylinder, pressure cylinder, and support frame are flush.

[0011] Preferably, the coil spring is sleeved on the outside of the connecting block, and the end of the coil spring is fixedly connected to the inner wall of the connecting groove.

[0012] Preferably, the two ends of the pressure cylinder are locked inside the slot, and the pressure cylinder is located between two adjacent sets of rotating cylinders.

[0013] Preferably, the support frame is provided in two sets, and the support frame has an "L" shaped structure.

[0014] Preferably, the padded grip bar is located on the underside of the two sets of support frames.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting a rotatable movable arm, this utility model can drive the pressure cylinder to press on the top surface of the plate, so that the plate is placed on the top surface of the rotating cylinder in a stable manner, reducing the workload of workers and improving the ease of use of the device.

[0016] 1. This utility model, by setting a positioning structure, allows the movable arm to rotate when the soft pad grip is pressed down. The movable arm drives the connecting block to rotate inside the connecting groove. When the connecting block rotates, it causes the coil spring to undergo elastic deformation, and the front end of the movable arm tilts downward, while the rear end of the movable arm rises upward. The movable arm then drives the pressure cylinder at the rear end to rise from inside the slot, and the pressure cylinder moves upward away from the rotating cylinder and pushes the plate backward. The plate can roll on the rotating cylinder so that the rear end of the rotating cylinder moves to the lower side of the pressure cylinder. When the soft pad grip is released, the movable arm and connecting block return to their original positions under the elastic action of the coil spring. The movable arm then drives the pressure cylinder to press down on the plate, which can fix the plate on the top surface of the rotating cylinder. There is no need for manual support of the plate, which reduces the workload of workers and improves the ease of use of the device.

[0017] 2. This utility model has a support structure. Pulling the support frame allows it to slide on the guide rod, adjusting the position of the two sets of support frames in front of the rotating cylinder. This places the plate on the top surface of the rotating cylinder, so that the rear end of the rotating cylinder is in front of the pressure cylinder. The support frame can support the bottom front end of the plate, so as to process longer plates and prevent the plate from bending due to the front end being suspended after placement.

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.

[0024] Please see Figures 1-4 This utility model provides an embodiment of a plate positioning device for a hydraulic guillotine shearing machine:

[0025] The body 1 and shear plate seat 11 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0026] A plate positioning device for a hydraulic guillotine shearing machine includes: a machine body 1, with a shearing seat 11 installed at the front end of the machine body 1;

[0027] A positioning structure 2 is installed on the top surface of the shearing base 11. The positioning structure 2 includes a fixing plate 21, which is fixedly installed on both sides of the top surface of the shearing base 11. A rotating cylinder 22 is movably installed on the inner side of the fixing plate 21 through a bearing. A slot 23 is opened at the rear end of the top surface of the fixing plate 21. A connecting groove 24 is opened on the front side wall of the fixing plate 21. A connecting block 25 is movably installed on the inner side of the connecting groove 24 through a bearing. A coil spring 26 is fixedly connected to the inside of the surface of the connecting block 25. A movable arm 27 is fixedly connected to the end of the connecting block 25. A pressure cylinder 28 is movably installed at the rear end of the movable arm 27 through a bearing. A soft pad handle 29 is fixedly connected to the front end of the movable arm 27. The movable arm 27 can rotate and move, which can drive the pressure cylinder 28 to press on the top surface of the plate, so that the plate is placed on the top surface of the rotating cylinder 22 stably, reducing the workload of workers and improving the ease of use of the device.

[0028] A support structure 3 is installed on the positioning structure 2. The support structure 3 includes a guide rod 31, which is fixedly connected to the front end of two sets of fixing plates 21. A support frame 32 is slidably installed on the guide rod 31.

[0029] Furthermore, the top surfaces of the shearing seat 11, rotating cylinder 22, pressure cylinder 28, and support frame 32 are flush, allowing the sheet metal to move on the shearing seat 11, rotating cylinder 22, pressure cylinder 28, and support frame 32 when it is not necessary to press down on the sheet metal.

[0030] Furthermore, the coil spring 26 is sleeved on the outside of the connecting block 25, and the end of the coil spring 26 is fixedly connected to the inner wall of the connecting groove 24. The coil spring 26 restores the movable arm 27, so that the pressure cylinder 28 presses on the top surface of the plate to provide power for fixing the plate.

[0031] Furthermore, the two ends of the pressure cylinder 28 are locked inside the slot 23, and the pressure cylinder 28 is located between two adjacent sets of rotating cylinders 22. The slot 23 provides support and limit for the installation of the pressure cylinder 28.

[0032] Furthermore, the support frame 32 is provided in two sets, and the support frame 32 has an "L" shaped structure, which can stably support the front end of the plate.

[0033] Furthermore, the padded grip bar 29 is located below the two sets of support frames 32, and the movement of the padded grip bar 29 is not obstructed by the support frames 32.

[0034] Working principle: During processing, the support frame 32 is pulled and slides on the guide rod 31. The position of the two sets of support frames 32 in front of the rotating cylinder 22 can be adjusted, and the plate is placed on the top surface of the rotating cylinder 22 so that the rear end of the rotating cylinder 22 is in front of the pressure cylinder 28. The support frame 32 can support the bottom surface of the front end of the plate so as to process longer plates and avoid the plate bending due to the front end being suspended after placement because of its length.

[0035] Pressing down the soft pad grip 29 causes the movable arm 27 to rotate. The movable arm 27 causes the connecting block 25 to rotate inside the connecting groove 24. When the connecting block 25 rotates, it causes the coil spring 26 to undergo elastic deformation. The front end of the movable arm 27 tilts downward, and the rear end of the movable arm 27 rises upward. The movable arm 27 then causes the rear pressure cylinder 28 to rise from inside the slot 23. The pressure cylinder 28 moves upward away from the rotating cylinder 22 and pushes the plate backward. The plate can roll on the rotating cylinder 22 so that the rear end of the rotating cylinder 22 moves to the lower side of the pressure cylinder 28. Releasing the soft pad grip 29 causes the movable arm 27 and the connecting block 25 to return to their original positions under the elastic action of the coil spring 26. The movable arm 27 then causes the pressure cylinder 28 to press down on the plate, which can fix the plate on the top surface of the rotating cylinder 22 without the need for manual support of the plate, reducing the workload of workers and improving the ease of use of the device.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description.
