Description

Technical Field

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

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is fitted with a nut. It is a type of fastener consisting of a head and a threaded shank. It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated. Therefore, a bolted connection is a detachable connection. Anti-loosening bolts usually need to be bent using a bending machine during the production process.

[0003] A search revealed a bolt bending machine for processing anti-loosening bolts, disclosed in publication number (CN218692851U). The machine includes a worktable, a clamping box fixedly connected to the front of the worktable, a motor fixedly connected to the top of the clamping box, a rotating shaft fixedly connected to the output end of the motor via a coupling, a threaded rod fixedly connected to the bottom of the rotating shaft, a bearing fixedly connected to the bottom of the threaded rod, a limit groove on one side of the clamping box, a threaded sleeve movably connected to the outer wall of the threaded rod, a connecting block fixedly connected to the outer wall of the threaded sleeve, a clamping block fixedly connected to one side of the connecting block, and an anti-slip pad fixedly connected to the top of the clamping block.

[0004] The implementation of this technical solution has at least the following drawbacks: although the utility model can bend bolts, the process of picking up, positioning, and bending each bolt individually is too cumbersome, thus affecting the bending efficiency and requiring improvement. Therefore, we propose a bolt bending machine for processing anti-loosening bolts. Utility Model Content

[0005] The purpose of this utility model is to provide a bolt bending machine for processing anti-loosening bolts, which solves the problem mentioned in the background art that requires each bolt to be picked up, positioned and bent one by one, which is too cumbersome and thus affects the bending efficiency of bolts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bolt bending machine for processing anti-loosening bolts, comprising a frame, a first hydraulic cylinder fixedly mounted on the upper end of the frame, a placement plate provided in the middle of the frame, a servo motor fixedly mounted on the lower end of the frame, a second hydraulic cylinder fixedly mounted on the upper end of the placement plate, a positioning plate mounted on the output end of the second hydraulic cylinder, multiple placement slots provided on the upper end of the placement plate in a ring-shaped arrangement, a through slot provided on the lower end of the placement slots, a fixing plate provided on the lower end of the placement plate, multiple push rods welded to the upper end of the fixing plate in a ring-shaped arrangement, and support wheels fixedly mounted on both sides of the lower end of the fixing plate.

[0007] By adopting the above technical solution, multiple pressing parts on the positioning plate can simultaneously tighten and limit multiple bolts, thus eliminating the trouble of workers picking and positioning them one by one. After the positioning plate is pressed into place, the support wheels on the fixed plate can contact the lower end of the frame, thereby providing auxiliary support for the placement plate and avoiding the impact of bending force on the transmission rod during bending. The positioning plate can also be controlled to move upward and reset, so that the push rod on the fixed plate can simultaneously push out the bent bolts in the placement groove, thus eliminating the trouble of workers removing them one by one and further improving the bolt bending effect.

[0008] Optionally, the lower end of the positioning plate is welded with multiple pressing parts, each of which corresponds to a placement groove.

[0009] By adopting the above technical solution and setting up the pressure component, the bolt can be positioned.

[0010] Optionally, a bending plate is installed at the output end of the first hydraulic cylinder, and the bending plate is located on the right side of the placement plate.

[0011] By adopting the above technical solution and setting up a bending plate, the bolts can be bent.

[0012] Optionally, the output end of the servo motor is equipped with a transmission rod, the upper end of which is detachably connected to the lower middle part of the placement plate.

[0013] By adopting the above technical solution and setting up the transmission rod, the placement plate can be driven to rotate.

[0014] Optionally, the size of the push rod is adapted to the size of the through groove, and the push rod is movably connected to the through groove.

[0015] By adopting the above technical solution, the bent bolt can be ejected by the cooperation of the push rod and the through groove.

[0016] Optionally, a connecting rod is welded to the lower end of the positioning plate, and the lower end of the connecting rod passes through and is fixedly connected to the upper end of the placement plate and the fixing plate.

[0017] By adopting the above technical solution and setting the connecting rod, the fixed plate can be moved during the movement of the positioning plate.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the setting of a frame, bending plate, second hydraulic cylinder, pressing component, servo motor, push rod, and support wheel, can simultaneously tighten and limit multiple bolts on the positioning plate by multiple pressing components, thus eliminating the trouble of workers picking and positioning them one by one. At this time, after the positioning plate is pressed into place, the support wheel on the fixed plate can contact the lower end of the frame, thereby providing auxiliary support for the placement plate and avoiding the influence of bending force on the transmission rod during bending. It can also control the positioning plate to move upward and reset, so that the push rod on the fixed plate can simultaneously push out the bent bolts in the placement groove, thus eliminating the trouble of workers removing them one by one and further improving the bolt bending effect.

[0025] Please see Figure 1-3This utility model provides a technical solution: a bolt bending machine for processing anti-loosening bolts, including a frame 1, a first hydraulic cylinder 11 fixedly installed at the upper end of the frame 1, a placement plate 13 arranged in the middle of the frame 1, a servo motor 25 fixedly installed at the lower end of the frame 1, a second hydraulic cylinder 2 fixedly installed at the upper end of the placement plate 13, a positioning plate 21 installed at the output end of the second hydraulic cylinder 2, a plurality of placement grooves 23 are opened at the upper end of the placement plate 13 and are arranged in a ring, a through groove 24 is opened at the lower end of the placement grooves 23, a fixing plate 3 is arranged at the lower end of the placement plate 13, a plurality of push rods 4 are welded to the upper end of the fixing plate 3 and are arranged in a ring, and the lower end of the fixing plate 3 has two sides Each is fixedly equipped with a support wheel 5. The output end of the servo motor 25 is equipped with a transmission rod 26. The upper end of the transmission rod 26 is detachably connected to the lower middle part of the placement plate 13. Through the setting of the transmission rod 26, the placement plate 13 can be driven to rotate. The size of the push rod 4 is adapted to the size of the through groove 24, and the push rod 4 is movably connected to the through groove 24. Through the cooperation of the push rod 4 and the through groove 24, the bent bolt can be pushed out. The lower end of the positioning plate 21 is welded with a connecting rod 27. The lower end of the connecting rod 27 passes through and is fixedly connected to the upper end of the placement plate 13 and the fixed plate 3. Through the setting of the connecting rod 27, the fixed plate 3 can be driven to move during the movement of the positioning plate 21.

[0026] Multiple pressing parts 22 are welded to the lower end of the positioning plate 21. Each pressing part 22 corresponds to a placement groove 23. The bolts can be positioned by setting the pressing parts 22.

[0027] A bending plate 12 is installed at the output end of the first hydraulic cylinder 11. The bending plate 12 is located on the right side of the placement plate 13. The bending plate 12 allows the bolt to be bent.

[0028] During bending, the bolts to be bent are first placed one by one into the placement slot 23. Then, the second hydraulic cylinder 2 is opened, which drives the positioning plate 21 to move downward. This causes multiple pressing parts 22 on the positioning plate 21 to simultaneously press and limit multiple bolts, thus eliminating the need for workers to pick up and position them one by one. After the positioning plate 21 is pressed into place, the support wheel 5 on the fixed plate 3 contacts the lower end of the frame 1, thereby providing auxiliary support for the placement plate 13 and avoiding the impact of bending force on the transmission rod 26 during the bending process. The system then controls the servo motor 25 to drive the transmission rod 26 to rotate, moving the positioned bolts below the bending plate 12. The first hydraulic cylinder 11 then drives the bending plate 12 downwards to bend the bolts, thus quickly bending multiple positioned bolts. After bending, the positioning plate 21 can be controlled to move upwards and reset, causing the push rod 4 on the fixing plate 3 to simultaneously eject the bent bolts from the placement groove 23, saving workers the trouble of removing them one by one and further improving the bolt bending effect.
