Description

Technical Field

[0001] This utility model relates to the field of hardware processing technology, and in particular to a straightening fixture for hardware processing. Background Technology

[0002] Straightening fixtures for metal processing parts are auxiliary equipment used in the metal manufacturing industry to repair deformed parts. They are mainly used to address dimensional deviations and shape deformations caused by material elasticity, thermal stress, or external forces during processes such as stamping, bending, and casting. These problems include issues such as incomplete bending, flat warping, and internal cavity depressions. This fixture can reduce the scrapping of defective parts, improve processing accuracy, and is widely used in the secondary straightening treatment of small-sized plates, brackets, valve cap castings, and other metal parts.

[0003] However, due to the single pitch angle of the straightening fixture for metal processing parts, it is difficult to make accurate angle compensation according to the actual deformation error of the workpiece. This can easily lead to incomplete or over-correction, affecting the dimensional accuracy and appearance quality of the processed parts. The angle adjustment operation is inconvenient and requires additional time to adjust or replace the matching tools, which significantly reduces the efficiency of the straightening operation and increases the intensity of manual labor. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing straightening fixtures for metal processing parts, which have a single pitch angle, making it difficult to accurately compensate for the actual deformation error of the workpiece. This can easily lead to incomplete or over-correction, affecting the dimensional accuracy and appearance quality of the processed parts. The angle adjustment operation is inconvenient, requiring additional time to adjust or replace the matching tools, which significantly reduces the efficiency of straightening operations and increases the intensity of manual labor. Therefore, a straightening fixture for metal processing parts is proposed.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a straightening fixture for metal processing parts, comprising a base, a support, a clamping fixture, a threaded rod, and an adjusting device. The support is fixed to the surface of the base, the clamping fixture is rotatably connected to the surface of the support, the threaded rod is threadedly connected to the surface of the clamping fixture, the adjusting device is disposed on the lower surface of the clamping fixture, the adjusting device includes a circle, the circle is fixedly connected to the clamping fixture, the surface of the circle has an adjusting hole, and a retaining sleeve is fixedly connected to the upper surface of the base, the inner wall of the retaining sleeve is inserted... The fixture is equipped with an insert rod that is inserted into an adjustment hole on the surface of a circle. A circular block is rotatably connected to the lower surface of the insert rod, and a grip rod is fixedly connected to the surface of the circular block. By setting an adjustment device, the pitch angle of the fixture can be flexibly adjusted. During adjustment, the fixture only needs to be rotated to a suitable angle, and the angle can be quickly fixed by the cooperation of the grip rod, the fixing spring, and the insert rod. This solves the problem of the original fixture having a single pitch angle and being difficult to adjust. It can adapt to the correction needs of hardware processing parts of different shapes and sizes, while ensuring reliable angle fixation, reducing correction deviation, and improving correction accuracy and ease of operation.

[0006] Preferably, the surface of the ferrule has a notch, and the gripping rod engages with the notch on the surface of the ferrule. By setting the gripping rod, after the fixture is rotated to a suitable pitch angle, the gripping rod can be rotated to reach the notch, which can release the restraint on the fixing spring. This provides the trigger condition for the fixing spring to release its elastic force, squeeze the insert rod into the circle, and finally achieve reliable fixation of the fixture angle. This ensures that the angle can be quickly locked after adjustment, and guarantees the accuracy and stability of subsequent metal processing parts straightening operations.

[0007] Preferably, a fixing spring is fixedly connected to the lower surface of the circular block. The end of the fixing spring away from the circular block is fixedly connected to the base. By setting the fixing spring, when the gripping rod rotates to the notch and loses its restraint, an elastic force is generated. This elastic force can squeeze the insertion rod to insert it into the circle, thereby achieving rapid and reliable fixation of the pitch angle of the fixture tooling. This avoids the tooling from shifting its angle during the straightening operation of the hardware processing parts, and thus solves the problem that the original tooling angle fixation is unreliable and easily leads to straightening deviation.

[0008] Preferably, the circular surface has multiple adjustment holes arranged in a circumferential array along the circular surface. By setting the circular surface, when the fixture rotates to a suitable pitch angle, the fixing spring squeeze rod is inserted into the corresponding position of the circular surface. Through the engagement of the rod and the circular surface, the rotation of the fixture is directly restricted, thereby achieving stable angle locking.

[0009] Preferably, the surface of the fixture is provided with a picking component, which includes a lifting plate. The lifting plate is rotatably connected to the fixture and is located in the inner wall of the fixture. By setting the picking component, after the workpiece is straightened, rotating the threaded rod can release the fixation. The pressure spring will automatically squeeze the lifting plate to squeeze the workpiece out, eliminating the need for manual picking. This reduces damage to the workpiece or hands during picking, simplifies the picking process, saves picking time, and further improves the overall straightening operation efficiency.

[0010] Preferably, one end of the fixture is fixedly connected to a clamping block, and the surface of the clamping block is provided with an inclined surface.

[0011] Preferably, a pressure spring is fixedly connected to the inclined surface of the clamping block, and the end of the pressure spring away from the clamping block is fixedly connected to the lifting plate. By setting the pressure spring, after the workpiece is straightened and the threaded rod is rotated to release the fixation, the spring force released when it is no longer restrained directly squeezes the lifting plate and pushes the lifting plate to rotate, thereby actively squeezing out the workpiece in the tooling.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an adjustment device, when the pitch angle of the fixture needs to be adjusted, the fixture is rotated. When the fixture reaches a suitable angle, the handle is rotated to the notch. Then, the fixed spring is released and generates elastic force to squeeze the insert rod into the circle. At this time, the angle of the fixture is fixed, and the adjustment is completed. By setting an adjustment device, the pitch angle of the fixture can be flexibly adjusted. During adjustment, it is only necessary to rotate the fixture to a suitable angle, and the angle can be quickly fixed by the cooperation of the handle, the fixed spring and the insert rod. This solves the problem of the original fixture having a single pitch angle and being difficult to adjust. It can adapt to the correction needs of hardware processing parts of different shapes and sizes, while ensuring reliable angle fixation, reducing correction deviation, and improving correction accuracy and ease of operation.

[0013] In this invention, by setting up a picking component, after the workpiece is straightened, rotating the threaded rod contacts the fixation of the workpiece. Subsequently, the pressure spring is released from its restraint and generates elastic force to squeeze the lifting plate and squeeze out the workpiece. By setting up the picking component, after the workpiece is straightened, rotating the threaded rod can release the fixation, and the pressure spring will automatically squeeze the lifting plate to squeeze out the workpiece. There is no need to manually pick up the workpiece, which reduces the risk of damage to the workpiece or hands during the picking process, simplifies the picking process, saves picking time, and further improves the overall straightening operation efficiency.

[0016] Please see Figures 1-5This utility model provides a technical solution: a straightening fixture for hardware processing parts, including a base 1, a bracket 2, a clamping fixture 3, a threaded rod 4 and an adjusting device 5. The bracket 2 is fixed on the surface of the base 1, the clamping fixture 3 is rotatably connected to the surface of the bracket 2, the threaded rod 4 is threadedly connected to the surface of the clamping fixture 3, and the adjusting device 5 is set on the lower surface of the clamping fixture 3.

[0017] In this implementation scheme: the adjustment device 5 includes a circle 51, which is fixedly connected to the fixture 3. The surface of the circle 51 is provided with an adjustment hole. A sleeve 53 is fixedly connected to the upper surface of the base 1. A rod 52 is inserted into the inner wall of the sleeve 53. The rod 52 is inserted into the adjustment hole on the surface of the circle 51. A block 54 is rotatably connected to the lower surface of the rod 52. A handle 56 is fixedly connected to the surface of the block 54. By setting the adjustment device 5, the pitch angle of the fixture 3 can be flexibly adjusted. During adjustment, the fixture only needs to be rotated to a suitable angle. The angle can be quickly fixed by the cooperation of the handle 56, the fixing spring 57 and the rod 52. This solves the problem of the original fixture having a single pitch angle and being difficult to adjust. It can adapt to the correction needs of hardware processing parts of different shapes and sizes, while ensuring reliable angle fixation, reducing correction deviation, and improving correction accuracy and ease of operation.

[0018] Specifically, the surface of the ferrule 53 has a notch, and the gripping rod 56 engages with the notch on the surface of the ferrule 53. By setting the gripping rod 56, after the fixture 3 is rotated to a suitable pitch angle, the gripping rod 56 is rotated to reach the notch, which releases the restraint on the fixing spring 57. This provides the trigger condition for the fixing spring 57 to release its elastic force to squeeze the insertion rod 52 into the circle 51, and finally achieve reliable fixation of the angle of the fixture 3. This ensures that the angle can be quickly locked after adjustment, and guarantees the accuracy and stability of subsequent metal processing parts straightening operations.

[0019] Specifically, a fixing spring 57 is fixedly connected to the lower surface of the round block 54. The end of the fixing spring 57 away from the round block 54 is fixedly connected to the base 1. By setting the fixing spring 57, when the gripping rod 56 rotates to the notch and loses its restraint, it generates elastic force. This elastic force can squeeze the insertion rod 52 to insert it into the circle 51, thereby realizing the quick and reliable fixation of the pitch angle of the fixture 3, avoiding the angle deviation of the fixture during the straightening operation of the hardware processing parts, and thus solving the problem that the original fixture angle fixation is unreliable and easily leads to the straightening deviation.

[0020] Specifically, there are multiple adjustment holes on the surface of the circle 51. The adjustment holes on the surface of the circle 51 are arranged in a circumferential array along the circle 51. By setting the circle 51, when the fixture 3 rotates to a suitable pitch angle, the fixing spring 57 presses the insert rod 52 into the corresponding position of the circle 51. Through the engagement of the insert rod 52 and the circle 51, the rotation of the fixture 3 is directly restricted, and the angle is stably locked.

[0021] Specifically, the surface of the fixture 3 is provided with a pick-up component 55, which includes a lifting plate 551. The lifting plate 551 is rotatably connected to the fixture 3 and is located in the inner wall of the fixture 3. By setting the pick-up component 55, after the workpiece is straightened, the threaded rod 4 can be rotated to release the fixation. The pressure spring 553 will automatically squeeze the lifting plate 551 to squeeze the workpiece out, eliminating the need for manual pick-up. This reduces damage to the workpiece or hands during pick-up, simplifies the pick-up process, saves pick-up time, and further improves the overall straightening operation efficiency.

[0022] Specifically, one end of the fixture 3 is fixedly connected to a locking block 552, and the surface of the locking block 552 is provided with an inclined surface.

[0023] Specifically, a pressure spring 553 is fixedly connected to the inclined surface of the locking block 552, and the end of the pressure spring 553 away from the locking block 552 is fixedly connected to the lifting plate 551.

[0024] In this embodiment: by setting a pressure spring 553, after the workpiece is straightened and the threaded rod 4 is released from its fixed position, the spring force released when it is no longer restrained directly squeezes the lifting plate 551 and pushes the lifting plate 551 to rotate, thereby actively squeezing out the workpiece in the tooling.

[0025] Working principle: By setting the adjustment device 5, when the pitch angle of the fixture 3 needs to be adjusted, the fixture 3 is rotated. When the fixture 3 reaches the appropriate angle, the handle 56 is rotated to the notch. Then the fixed spring 57 is released and generates elastic force to squeeze the insert rod 52 into the circle 51. At this time, the angle of the fixture 3 is fixed and the adjustment is completed. By setting the adjustment device 5, the pitch angle of the fixture 3 can be flexibly adjusted. When adjusting, it is only necessary to rotate the fixture to the appropriate angle. With the cooperation of the handle 56, the fixed spring 57 and the insert rod 52, the angle can be quickly fixed. This solves the problem of the original fixture pitch angle being single and difficult to adjust. It can adapt to the correction needs of hardware processing parts of different shapes and sizes, while ensuring reliable angle fixation, reducing correction deviation, and improving correction accuracy and ease of operation. By setting up the pick-up component 55, after the workpiece is straightened, rotating the threaded rod 4 will contact the fixation of the workpiece. Then, the pressure spring 553 will lose its restraint and generate elastic force to squeeze the lifting plate 551 to rotate and squeeze out the workpiece. By setting up the pick-up component 55, after the workpiece is straightened, rotating the threaded rod 4 can release the fixation. The pressure spring 553 will automatically squeeze the lifting plate 551 to squeeze out the workpiece, eliminating the need for manual pick-up. This reduces the risk of damage to the workpiece or hands during pick-up, simplifies the pick-up process, saves pick-up time, and further improves the overall straightening operation efficiency.
