Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically a workpiece bending fixture. Background Technology

[0002] Bending is mainly used for cutting, forming, and straightening metal sheets. It is a processing method that involves bending a section of metal sheet to form the required shape and size, and then using certain tools to cut, form, and straighten the sheet to achieve the desired shape and size.

[0003] Existing methods often involve using workpiece bending fixtures to bend the workpiece. When using these fixtures, the user needs to first fix the workpiece in a suitable position and then activate the bending structure to bend it. This makes the operation of the workpiece bending fixtures cumbersome and inconvenient. Therefore, a workpiece bending fixture is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A workpiece bending fixture of this utility model includes a frame, an inner groove for placing the workpiece, a first hydraulic cylinder fixedly connected to the inner side of the frame, a clamping plate fixedly connected to the output end of the first hydraulic cylinder, a synchronization plate fixedly connected to the outer side of the clamping plate, the synchronization plate and the frame being slidably connected, a power supply fixedly connected to the outer side of the synchronization plate, a plug provided on the outer side of the power supply, a motor fixedly connected to the outer side of the frame, a socket provided on the outer side of the motor, the plug and socket being used in conjunction, a reciprocating screw fixedly connected to the output end of the motor, a pressure block threadedly connected to the outer side of the reciprocating screw, and the pressure block slidingly connected to the frame. Connection; This step involves setting up a clamping plate, a synchronization plate, a plug, a socket, and a pressure block. During use, the user simply places the workpiece to be bent into the placement slot. The first hydraulic cylinder moves the clamping plate to the placement slot to clamp and fix the workpiece. After clamping, the downward movement of the clamping plate causes the synchronization plate to move the power supply downward, allowing the plug to be fully inserted into the socket. This starts the motor, which in turn drives the reciprocating screw to rotate, causing the pressure block to move downward to bend the workpiece. After bending, the pressure block rises again due to the rotation of the reciprocating screw. The user only needs to start and stop the first hydraulic cylinder to complete the clamping and bending processes, making the device more convenient to operate and improving its usability.

[0006] Preferably, a grating is fixedly connected to the outside of the frame. The gratings work together, and a second hydraulic cylinder is electrically connected to the outside of the grating. A push block is fixedly connected to the output end of the second hydraulic cylinder, and a blocking screw is threadedly connected to the inside of the pressure block. By setting up the grating, the second hydraulic cylinder, the push block, and the blocking screw, when the workpiece bent by the pressure block needs to be bent again, the blocking screw can be screwed into the inside of the pressure block. After the pressure block moves to its maximum position, the blocking screw will separate the two gratings, causing the gratings to send a signal to the second hydraulic cylinder, which will drive the push block to push out. This will cooperate with the pressure block to further bend the workpiece. After bending, the pressure block rises, and the blocking screw no longer blocks the grating, causing the second hydraulic cylinder to drive the push block back into position. This further expands the applicability of the device and improves its practicality.

[0007] Preferably, a movable block is slidably connected to the inner side of the frame, and the movable block is slidably connected to the placement groove. By setting the movable block, after the workpiece is bent, the movable block can be pulled up to push the workpiece, thereby making it easier to remove the workpiece from the inside of the placement groove and improving the convenience of using the device.

[0008] Preferably, a limiting plate is fixedly connected to the outside of the movable block, and a baffle is fixedly connected to the outside of the frame. The limiting plate and the baffle work together. By setting the limiting plate and the baffle, when the movable block moves to its maximum position, the baffle can restrict the limiting plate, thereby restricting the movable block and making it less likely to separate from the placement slot, thus improving the convenience of using the device.

[0009] Preferably, a pull-up spring is fixedly connected to the outer side of one side of the baffle, and the pull-up spring is fixedly connected to the limiting plate. This step, by setting the pull-up spring, allows the limiting plate and the movable block to be subjected to additional pulling force other than that of the user when the workpiece needs to be taken out from the inside of the placement slot. This makes the pushing of the workpiece smoother and more stable, and improves the stability of the device.

[0010] Preferably, a guide rod is fixedly connected to the outside of the power supply, and a connecting plate is fixedly connected to the outside of the motor. The guide rod and the connecting plate are slidably connected. This step, by setting the guide rod and the connecting plate, allows the power supply to be inserted into the inside of the connecting plate through the guide rod, thereby facilitating alignment with the motor, making the connection between the two more stable, and improving the stability of the device.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a clamping plate, a synchronous plate, a plug, a socket, and a pressure block, allows the user to directly place the workpiece to be bent into the placement slot during use. The first hydraulic cylinder drives the clamping plate to move to match the placement slot and clamp the workpiece. After clamping, the downward movement of the clamping plate causes the synchronous plate to move the power supply downward, thereby allowing the plug to be fully inserted into the socket. This starts the motor, which drives the reciprocating screw to rotate, causing the pressure block to move downward to bend the workpiece. After bending, the pressure block rises again due to the rotation of the reciprocating screw. This allows the user to complete the clamping and bending processes simply by starting and stopping the first hydraulic cylinder, making the operation of the device more convenient and improving its usability.

[0013] 2. This utility model, by setting up a grating, a second hydraulic cylinder, a push block, and a blocking screw, allows for the re-bending of a workpiece after it has been bent by the pressure block. The blocking screw is screwed into the inside of the pressure block, and when the pressure block moves to its maximum position, the blocking screw separates the two gratings. This causes the gratings to send a signal to the second hydraulic cylinder, which in turn drives the push block to extend, thus cooperating with the pressure block to further bend the workpiece. After bending, the pressure block rises, causing the blocking screw to no longer block the grating, allowing the second hydraulic cylinder to return the push block to its original position. This further expands the applicability of the device and improves its practicality. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, a workpiece bending fixture includes a frame 1. A placement groove 2 is formed on the inner side of the frame 1. A first hydraulic cylinder 3 is fixedly connected to the inner side of the frame 1. A clamping plate 4 is fixedly connected to the output end of the first hydraulic cylinder 3. A synchronization plate 5 is fixedly connected to the outer side of the clamping plate 4. The synchronization plate 5 and the frame 1 are slidably connected. A power supply 6 is fixedly connected to the outer side of the synchronization plate 5. A plug 7 is provided on the outer side of the power supply 6. A motor 8 is fixedly connected to the outer side of the frame 1. A socket 801 is provided on the outer side of the motor 8. The plug 7 and the socket 801 are used in conjunction. A reciprocating screw 9 is fixedly connected to the output end of the motor 8. A pressure block 10 is threadedly connected to the outer side of the reciprocating screw 9. The pressure block 10 and the frame 1 are slidably connected. This step involves setting a clamping plate... The device consists of plate 4, synchronization plate 5, plug 7, socket 801, and pressure block 10. In use, the user simply places the workpiece to be bent into the placement slot 2. The first hydraulic cylinder 3 moves the clamping plate 4 to the placement slot 2 to clamp and fix the workpiece. After clamping, the downward movement of the clamping plate 4 causes the synchronization plate 5 to move the power supply 6 downward, allowing the plug 7 to be fully inserted into the socket 801. This activates the motor 8, which in turn drives the reciprocating screw 9 to rotate, causing the pressure block 10 to move downward to bend the workpiece. After bending, the reciprocating screw 9 rotates, causing the pressure block 10 to rise again. The user only needs to start and stop the first hydraulic cylinder 3 to complete the clamping and bending processes, making the device more convenient and improving its usability.

[0024] Furthermore, such as Figure 1As shown, a grating 11 is fixedly connected to the outside of the frame 1. The gratings 11 cooperate with each other. A second hydraulic cylinder 12 is electrically connected to the outside of the grating 11. A push block 13 is fixedly connected to the output end of the second hydraulic cylinder 12. A blocking screw 14 is threadedly connected to the inside of the pressure block 10. In this step, by setting up the grating 11, the second hydraulic cylinder 12, the push block 13, and the blocking screw 14, when it is necessary to bend the workpiece after it has been bent by the pressure block 10 again, the blocking screw 14 can be screwed into the pressure block. Inside the pressure block 10, after the pressure block 10 moves down to its maximum position, the blocking screw 14 will separate the two gratings 11, so that the gratings 11 send a signal to the second hydraulic cylinder 12, causing it to drive the push block 13 out, thereby cooperating with the pressure block 10 to further bend the workpiece. After bending, due to the rise of the pressure block 10, the blocking screw 14 no longer blocks the gratings 11, thereby causing the second hydraulic cylinder 12 to drive the push block 13 back to its position, further expanding the applicability of the device and improving its practicality.

[0025] Furthermore, such as Figure 1 As shown, a movable block 15 is slidably connected to the inner side of the frame 1, and the movable block 15 is slidably connected to the placement groove 2. By setting the movable block 15, after the workpiece is bent, the movable block 15 can be pulled up to push the workpiece, thereby making it easier to take the workpiece out from the inside of the placement groove 2, which improves the convenience of using the device.

[0026] Furthermore, such as Figure 1 As shown, a limiting plate 16 is fixedly connected to the outside of the movable block 15, and a baffle 17 is fixedly connected to the outside of the frame 1. The limiting plate 16 and the baffle 17 work together. By setting the limiting plate 16 and the baffle 17, when the movable block 15 moves to the maximum position, the baffle 17 can restrict the limiting plate 16, thereby restricting the movable block 15 and making it less likely to separate from the placement groove 2, thus improving the convenience of using the device.

[0027] Furthermore, such as Figure 1 As shown, a pull-up spring 18 is fixedly connected to the outer side of the baffle 17 on one side, and the pull-up spring 18 is fixedly connected to the limiting plate 16. By setting the pull-up spring 18, when the workpiece needs to be taken out from the inside of the placement slot 2, the contraction of the pull-up spring 18 can allow the limiting plate 16 and the movable block 15 to be subjected to additional pulling force other than that of the user, making the pushing of the workpiece smoother and more stable, and improving the stability of the device.

[0028] Furthermore, such as Figure 1As shown, a guide rod 19 is fixedly connected to the outside of the power supply 6, and a connecting plate 20 is fixedly connected to the outside of the motor 8. The guide rod 19 and the connecting plate 20 are slidably connected. This step, by setting the guide rod 19 and the connecting plate 20, allows the power supply 6 to be inserted into the inside of the connecting plate 20 through the guide rod 19, thereby facilitating alignment with the motor 8, making the connection between the two more stable, and improving the stability of the device.

[0029] Working principle: The user directly places the workpiece to be bent into the placement slot 2. The first hydraulic cylinder 3 drives the clamping plate 4 to move to the placement slot 2 to clamp and fix the workpiece. After clamping, the downward movement of the clamping plate 4 causes the synchronous plate 5 to drive the power supply 6 to move downward, thereby allowing the plug 7 to be fully inserted into the socket 801. This causes the power supply 6 to start the motor 8, which drives the reciprocating screw 9 to rotate. The reciprocating screw 9 drives the pressure block 10 to move downward, bending the workpiece. After the 0 is moved to the maximum position, the blocking screw 14 will separate the two gratings 11, so that the grating 11 sends a signal to the second hydraulic cylinder 12, causing it to drive the push block 13 out, thereby cooperating with the pressure block 10 to further bend the workpiece. After bending, due to the rise of the pressure block 10, the blocking screw 14 no longer blocks the grating 11, which causes the second hydraulic cylinder 12 to drive the push block 13 back to its position. Then, the user pulls the movable block 15, so that the movable block 15 pushes the workpiece out from the inside of the placement slot 2.
