Description

Technical Field

[0001] This utility model relates to the technical field of metal parts processing, and in particular to the technical field of a U-shaped metal parts correction device. Background Technology

[0002] In the production and processing of metal parts such as hardware and pipes, it is often necessary to bend metal materials into U-shapes. Due to factors such as material springback and processing errors, the two legs of the formed U-shaped metal parts (especially pipes made of softer materials such as brass) often have defects such as uneven opening, poor parallelism, and irregular overall shape, affecting subsequent assembly and use. Currently, there is a lack of a dedicated device for quickly and accurately reshaping and correcting U-shaped parts, especially U-shaped pipes. Conventional correction methods rely on manual hammering or general-purpose clamps, which are inefficient, lack precision, involve high labor intensity, pose safety hazards, and cannot adapt to the mass production of U-shaped parts of different sizes and specifications. Utility Model Content

[0003] The purpose of this invention is to solve the problems of low efficiency, poor precision, insufficient safety and weak versatility in the existing technology, and to propose a U-shaped metal part correction device that is compact in structure, precise in adjustment, safe in operation and can adapt to U-shaped parts of different specifications.

[0004] To achieve the above objectives, this utility model proposes a U-shaped metal part correction device, including a frame base plate, a transverse slide rail fixedly mounted on the frame base plate, and a left correction module slidably mounted on the transverse slide rail. The left correction module includes a first base, a pair of first movable blocks, a pair of sleeves, and a pair of hemispherical rods. The first base itself is a slider that cooperates with the transverse slide rail, and its top has an upward-opening U-shaped structure, thus forming a guide groove. The pair of first movable blocks are slidably disposed within the guide groove. The pair of sleeves are respectively fixedly mounted on the pair of first movable blocks. The pair of hemispherical rods are coaxially arranged with the pair of sleeves, with their hemispherical ends facing the side of the U-shaped metal part to be fed in; the rod portion of the hemispherical rod is a smooth rod or a lead screw structure, which can move or be fixed relative to the first movable blocks. The device also includes a center distance adjustment and locking mechanism; the center distance adjustment and locking mechanism includes a pair of limit screws and a pair of locking elements; the pair of limit screws are screwed into threaded holes on the vertical walls on both sides of the first base, and the inner ends of the limit screws can abut against the outer side of the first movable block; the pair of locking elements are detachably installed at the top opening of the first base. When the center distance needs to be adjusted, the clamping force of the locking elements on the first movable block is removed, and the first movable block can slide manually in the guide groove; after adjustment, the locking elements are installed and tightened to press and fix the first movable block in the guide groove, thereby realizing the setting and fixing of the center distance between the two sleeves; the limit screws can be screwed on their ends during the adjustment process to abut against the first movable block, playing an auxiliary positioning role.

[0005] Preferably, the system also includes an intermediate adjustment module and a linkage mechanism. The intermediate adjustment module includes a second base and a pair of second movable blocks. The second base is slidably mounted on a transverse slide rail, and its top is an upward-opening C-shaped structure. The pair of second movable blocks are slidably mounted within the C-shaped structure of the second base. The linkage mechanism includes two parallel synchronous adjustment screws. The left end of each synchronous adjustment screw is connected to a first movable block, and the right end is connected to a second movable block. The intermediate adjustment module has a limiting and locking mechanism identical to the center distance adjustment and locking mechanism, used to manually set and lock the position of the second movable blocks, and to drive the first movable block to move synchronously through the linkage mechanism. Its advantage is that the center distance adjustment operation can be transferred to an independent intermediate module, achieving human-machine isolation, making operation safer and more convenient.

[0006] Preferably, the system also includes a right-side support module and an overall transverse drive mechanism located to the right of the intermediate adjustment module. The right-side support module includes a third base slidably mounted on a transverse slide rail. The overall transverse drive mechanism includes a drive screw and a vertical mounting plate. The vertical mounting plate is fixedly mounted on the frame base plate and located to the right of the right-side support module. The left end of the drive screw is rotatably connected to the second base, and the right end is a threaded section that passes through a threaded hole provided on the vertical mounting plate. The right end of the drive screw is provided with a rotation operating part. By rotating the rotation operating part, the left-side correction module and the intermediate adjustment module, which are connected by a linkage mechanism, can be driven to move laterally as a whole. Its advantage lies in providing transverse adjustment capability for the entire correction station, facilitating alignment with the feeding mechanism.

[0007] Preferably, the hemispherical rod has a smooth section that slides through a through hole in the first movable block and is fixed in axial position by a locking nut. Its advantages include a simple structure and the ability to manually preset the correction depth.

[0008] Preferably, the rod portion of the hemispherical rod is a lead screw, which forms a threaded transmission pair with a drive nut. The drive nut is rotatably mounted on the first movable block. By driving the drive nut to rotate, the hemispherical rod can be moved along its axial direction. Its advantage is that the forward and backward movement of the hemispherical rod can be achieved through rotational drive, and it can be manually operated or connected to a motor for automatic correction.

[0009] Preferably, the drive nut is connected to a rotary drive device, which is a servo motor or a stepper motor. Its advantage lies in achieving automation and precise control of the correction process.

[0010] Preferably, the hemispherical rod is connected to a linear drive device, which is a cylinder, hydraulic cylinder, or electric actuator, used to drive the hemispherical rod to reciprocate along its axial direction. Its advantage lies in providing rapid, automated correction actions and high efficiency.

[0011] The beneficial effects of this utility model are: 1. Accurate and reliable core structure: This utility model accurately describes the mechanical principle of setting and fixing the center distance by means of manual pre-positioning, locking component pressing as the main method, and limit screw abutment as the auxiliary method. The structure is simple, the operation is intuitive, and the locking is reliable.

[0012] 2. Easy to adjust and highly versatile: The movable block can be manually slid to quickly adapt to U-shaped parts of different sizes, and the locking part provides a final secure lock, making it highly versatile.

[0013] 3. High rigidity and correction accuracy: The base adopts an integrated C-shaped structure, which has sufficient rigidity. The movable block is firmly fixed by obtaining huge friction through the locking device, which effectively avoids any movement during the correction process and ensures the shaping accuracy.

[0014] 4. High scalability: Based on the core module, it can be expanded into a complete device with remote synchronous adjustment and overall lateral adjustment functions to adapt to different production needs.

[0015] 5. High degree of automation: It can be easily connected to linear or rotary drive devices to automate the correction process and significantly improve production efficiency.

The device further includes a center distance adjustment and locking mechanism; the center distance adjustment and locking mechanism includes a pair of limiting screws 5 and a pair of locking elements 6; the pair of limiting screws 5 are respectively screwed into threaded holes opened on both sides of the vertical wall of the first base 1a by threaded connection, and the inner end of the limiting screw 5 can abut against the outer side of the first movable block 2a; the pair of locking elements 6 are detachably installed at the top opening of the first base 1a. When the center distance needs to be adjusted, the clamping force of the locking member 6 on the first movable block 2a is removed, and the first movable block 2a can be manually slid in the guide groove. After the adjustment is completed, the locking member 6 is installed and tightened to press and fix the first movable block 2a in the guide groove, thereby realizing the setting and fixing of the center distance between the two sleeves 3. The limiting screw 5 can be screwed on its end during the adjustment process to press against the first movable block 2a, which plays an auxiliary positioning role.

[0020] The working process of this utility model: The working process of this utility model, a U-shaped metal part correction device, is described in conjunction with the accompanying drawings.

[0021] Example 1 (Basic Type): like Figures 1 to 3 As shown, this basic U-shaped metal part correction device mainly includes a frame base plate 100, a transverse slide rail 101, and a left correction module A. The bottom of the first base 1a of the left correction module A is slidably engaged with the transverse slide rail 101. The top of the first base 1a has a U-shaped structure, forming a guide groove. A pair of first movable blocks 2a are placed in the guide groove and can be slid manually. A sleeve 3 is installed on each first movable block 2a. A hemispherical rod 4 is coaxially arranged with the sleeve 3. The center distance adjustment and locking mechanism includes a limit screw 5 and a locking element 6. The limit screw 5 is screwed into a threaded hole in the side wall of the first base 1a, and its inner end can be screwed out to abut against the outer surface of the first movable block 2a. The locking element 6 (in this example, a pressure block) is bolted to the top of the first base 1a.

[0022] Working principle (basic type): When adjusting the center distance, first loosen and remove the clamping force of the locking element 6 on the first movable block 2a. Then, manually move the two first movable blocks 2a so that the distance between the two sleeves 3 matches the center distance of the U-shaped part to be corrected. Tighten the limit screws 5 on both sides so that their ends tightly abut against the movable blocks 2a, which serves as an auxiliary positioning function. Finally, install and thoroughly tighten the locking element 6, using its strong downward pressure to firmly press and fix the first movable blocks 2a in the guide groove, completing the final setting and locking of the center distance. At this time, the first movable block 2a, sleeves 3, and first base 1a work as a rigid whole. The adjustment and correction actions of the hemispherical rod 4 are the same as described above.

[0023] Example 2 (Extended): Based on the basic model, an intermediate adjustment module and a right support module can be added to the transverse slide rail 101. The second base and movable block structure of the intermediate module are the same as those of the left module A, and are connected to the movable block 2a of the left module via a synchronous adjustment screw. The intermediate module is also adjusted by manually sliding the movable block, using limit screws for assistance, and locking the locking mechanism for final locking. The third base of the right support module is also slidably mounted on the slide rail 101. The overall transverse drive mechanism includes a drive screw 8 and a vertical mounting plate 9. The vertical mounting plate 9 is fixed to the frame base plate 100 and is located to the right of the right support module. The left end of the drive screw 8 is rotatably connected to the second base of the intermediate module, and the right end is threaded and passes through the threaded hole of the vertical mounting plate 9. A handwheel can be installed at the end as a rotation operation part 81. Rotating the rotation operation part 81 drives the entire transverse movement of the left correction module A and the intermediate adjustment module, while the position of the right support module remains unchanged.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
