Description

Technical Field

[0001] This utility model relates to the field of bolt processing technology, specifically to a bending machine for processing U-bolts. Background Technology

[0002] U-bolts, named for their U-shaped shape, have threads at both ends that allow them to be fitted with nuts. They are mainly used to secure tubular objects such as water pipes or sheet-like objects such as leaf springs in automobiles. During the manufacturing process, threads are typically machined into both ends of a horizontal bolt before it is bent using a bending machine.

[0003] For example, Chinese patent document CN220329669U discloses a bolt bending machine for processing U-shaped bolts, including a worktable and a bending model. One side of the bending model is provided with a fixed block driven by an electric cylinder that can clamp the bolt material. Positioning components are provided at both ends of the bolt material. On one side of the bolt material, on both sides of the fixed block, there are bending components driven by hydraulic cylinders to perform bending operations on the bolt material. The bending components include a U-shaped fixed block connected to the output end of the hydraulic cylinder and a bending roller connected to the U-shaped fixed block in a longitudinal rotation. A limit baffle is fixedly provided at the upper end of the U-shaped fixed block to prevent the bolt material from bending upward and bouncing during the bending process.

[0004] In the above technical solution, after the bolt is clamped by the fixing block, the bending assembly is pushed out by the hydraulic cylinder to bend the bolt. However, during long-term use, it was found that because the bending assembly is connected to the output end of the hydraulic cylinder, and the output end of the hydraulic cylinder is suspended, the output end of the hydraulic cylinder will bend due to the reaction force generated by the bolt when pushing the bolt to bend. This causes an angle between the output end of the hydraulic cylinder and the worktable, which means that the force output by the bending assembly cannot be perpendicular to the bolt when bending the bolt, thus affecting the bending quality of the bolt. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a bending machine for processing U-bolts, which can ensure the bending quality of bolts during long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending machine for processing U-bolts, comprising a worktable and an integrated plate. The worktable has a through mounting groove, and the integrated plate is connected to the worktable. The integrated plate has an abutment platform and a clamping cylinder. A clamping block is fixed to the output end of the clamping cylinder. The clamping block is used to press the bolt against the abutment platform. The integrated plate has a through arc-shaped guide groove, and a driving block is provided in the arc-shaped guide groove. The arc-shaped guide groove is used to limit the movement path of the driving block. A driving device is provided below the worktable. The driving device is used to drive the driving block to rotate, so as to press the bolt against the abutment platform to achieve bending of the bolt.

[0007] The present invention is further configured such that: the driving device includes a driving disk, the driving disk is rotatably connected to the bottom of the integrated plate, the driving block is detachably connected to the driving disk, a driven gear is provided at the center of the driving disk, a driving motor is provided below the driving disk, and a driving gear is fixed at the output end of the driving motor, the driving gear meshing with the driven gear.

[0008] The present invention is further configured such that: the driving block includes a limiting part and an abutting part; the driving disk is provided with a limiting groove adapted to the limiting part; the limiting part is installed in the limiting groove and extends upward to couple with the arc-shaped guide groove; the abutting part is located above the limiting part and is symmetrically arranged; an abutting space is formed between the two abutting parts to abut against the bolt; the driving block is provided with a through first threaded hole; the limiting groove is provided with a downward extending second threaded hole; the second threaded hole can be opposite to the first threaded hole and connected by a locking member.

[0009] The present invention is further configured such that: the integrated plate is provided with a positioning block, and the positioning block is provided with a positioning groove for the screw to be inserted.

[0010] The present invention is further configured such that: the abutting platform includes a clamping part and a coupling part, the clamping part and the coupling part are integrally formed, the peripheral wall of the clamping part is a plane, the peripheral wall of the coupling part is an arc surface, and the coupling part is partially fitted with the arc-shaped guide groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Because a drive device is provided to rotate the drive block, the drive block is rotated and the bolt is pressed against the abutment platform. With the cooperation of the abutment platform, the bolt can be bent. During the rotation of the drive block, the movement path of the drive block is limited by the arc-shaped guide groove, which ensures the stability of the drive block when pressing the bolt against the abutment platform. Therefore, it effectively solves the technical problem of the existing technology of moving the drive block by extending and retracting the hydraulic cylinder, which causes the drive block to have an inclination angle with the horizontal plane. This ensures the bending quality of the bolt during long-term use. Attached Figure Description

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figures 1 to 3 As shown, this utility model discloses a bending machine for processing U-bolts, including a worktable 1 and an integrated plate 2. An abutment platform 3 and a clamping cylinder 4 are mounted on the integrated plate 2. Thus, after the abutment platform 3 and the clamping cylinder 4 are pre-installed on the integrated plate 2, the integrated plate 2 is then installed on the worktable 1, which facilitates overall assembly and improves assembly efficiency.

[0019] In addition, a through mounting groove 101 is provided on the workbench 1, and a through arc-shaped guide groove 21 is provided on the integrated plate 2. A drive block 6 is provided in the arc-shaped guide groove 21. A drive device is provided below the workbench 1. The drive device is used to drive the drive block 6 to rotate. By extending and retracting the output end of the clamping cylinder 4, the clamping block 5 set at the output end of the clamping cylinder 4 is driven to move towards the abutment platform 3 so that the bolt is clamped between the clamping block 5 and the abutment platform 3. The drive device drives the drive block 6 to rotate and can drive the bolt to press against the abutment platform 3. With the cooperation of the abutment platform 3, the bolt can be bent. During the rotation of the drive block 6, the arc-shaped guide groove 21 can limit the movement path of the drive block 6 to ensure the stability of the drive block 6 when it drives the bolt to press against the abutment platform 3, thereby ensuring the bending quality of the bolt during long-term use.

[0020] Furthermore, the abutment platform 3 includes a clamping part 31 with a flat peripheral wall and a coupling part 32 with an arc peripheral wall. The clamping part 31 and the coupling part 32 are integrally formed. The coupling part 32 is partially fitted with the arc-shaped guide groove 21. This allows the abutment platform 3 to adapt to the path of the drive block 6 moving along the arc-shaped guide groove 21 through the coupling part 32, so as to better cooperate with the drive block 6. Since the peripheral wall of the clamping part 31 is flat, when the bolt is clamped between the clamping block 5 and the abutment platform 3, the contact between the abutment platform 3 and the bolt can be a line contact, thus ensuring the stability of clamping the bolt.

[0021] In this embodiment, the specific structure of the driving device includes a driving disk 71, which is rotatably connected to the bottom of the integrated plate 2. A driven gear 72 is provided at the center of the driving disk 71, and a driving motor 73 is provided below the driving disk 71. A driving gear 74 is fixed at the output end of the driving motor 73. The driving gear 74 meshes with the driven gear 72. Thus, the driving motor 73 drives the driving gear 74 to rotate, and the driven gear 72 meshing with the driving gear 74 drives the driving disk 71 to rotate. This drives the driving block 6 connected to the driving disk 71 to move toward the bolt, so as to press the bolt toward the abutment platform 3 and achieve the bending of the bolt. The driving gear 74 is a small gear, and the driven gear 72 is a large gear. By driving the large gear with the small gear, the driving block 6 can provide greater torque when bending the screw 100.

[0022] In this embodiment, the specific structure of the driving block 6 includes a limiting part 61 and an abutting part 62. The driving disk 71 is provided with a limiting groove 711 adapted to the limiting part 61. The limiting part 61 is installed in the limiting groove 711 and extends upward to couple with the arc-shaped guide groove 21. Thus, through the mutual contact between the limiting part 61 and the arc-shaped guide groove 21, the driving block 6 can be radially limited during the movement of the driving block 6 with the driving disk 71. In addition, the driving block 6 is provided with a through first threaded hole 600, and the limiting groove 711 is provided with a downwardly extending second threaded hole 712. 12 can be opposite to the first threaded hole 600 and connected by the locking member 200. In this way, by screwing in or out, the locking member 200 can form a threaded engagement with the first threaded hole 600 and the second threaded hole 712 respectively, so as to realize the detachable connection between the drive block 6 and the drive disk 71. After the locking member 200 is screwed in, the drive block 6 can be fixed. This can further prevent the deviation angle between the drive block 6 and the drive disk 71 when the drive block 6 is pressed against the bolt and the abutment platform 3, thus ensuring the stability of the bolt bending during long-term use.

[0023] Furthermore, by adapting the limiting groove 711 to the limiting part 61, it can play a positioning role when the limiting part 61 is connected to the drive disk 71. In addition, the abutting part 62 is symmetrically arranged above the limiting part 61, and an abutting space 621 is formed between the two abutting parts 62 to abut the bolt. In this way, when the drive block 6 presses the bolt against the abutting platform 3, the abutting space 621 formed can radially limit the bolt and prevent the bolt from springing up during the bending process.

[0024] In this embodiment, a positioning block 8 is further provided on the integrated plate 2. The positioning block 8 is provided with a positioning groove 81 for the screw 100 to be inserted. In this way, when the bolt is bent, the threaded head of the bolt can be inserted into the positioning groove 81, so as to position the bolt and facilitate subsequent bending of the bolt.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
