Description

Technical Field

[0001] This utility model relates to the field of bolt bending technology, and in particular to 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 consists of a head and a shank (a cylinder with external threads). 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. A bolt bending machine is a machine that can bend bolts.

[0003] A bolt fastener bending machine with publication number CN220781900U is described in this patent. This patent uses a buffer structure. The operator first places the bolt fastener workpiece inside the placement groove on the upper surface of the placement seat in the two sets of buffer structures. At this time, the operator starts the electric cylinder. The electric cylinder pushes out, causing the fitting groove on the lower surface of the extrusion head to fit against the upper surface of the bolt fastener workpiece. The fitting groove is arc-shaped, which avoids direct contact with one side of the bolt fastener workpiece and thus avoids damage to the threads.

[0004] The inventors discovered in their daily work that the distance between the two placement seats of the above-mentioned bolt fastener bending machine is not adjustable, which means that the device can only process and bend bolts of one length, resulting in a high degree of limitation in the use of the device. Utility Model Content

[0005] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing a bolt bending machine for processing anti-loosening bolts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bolt bending machine for processing anti-loosening bolts, comprising a base and a bolt rod, wherein a storage box is placed on the surface of the base, and an adjustment device is provided on the surface of the base, the adjustment device comprising two vertical plates fixedly installed on the surface of the base, a sliding rod fixedly installed between the two vertical plates, and two sliding seats slidably connected to the outer wall surface of the sliding rod.

[0007] Preferably, a U-shaped frame is fixedly installed on the side of each of the two sliding seats, and a round rod is fixedly installed on the inner wall surface of the vertical ends of the two U-shaped frames. A placement roller is fixedly installed between the two round rods, and an annular groove is formed on the annular side wall of the placement roller.

[0008] Preferably, an L-shaped bracket is fixedly installed on the surface of the base. A vertical groove is formed on the inner wall surface of the vertical end of the L-shaped bracket. A T-shaped plate is slidably connected inside the vertical groove. Two hinge plates are hinged to the bottom surface of the T-shaped plate. The end of the hinge plate away from the T-shaped plate is hinged to the sliding seat.

[0009] Preferably, an electric telescopic rod is fixedly installed on the top surface of the horizontal end of the L-shaped bracket, and the output end of the electric telescopic rod is fixedly connected to the T-shaped plate.

[0010] Preferably, a PLC controller and a cylinder are fixedly installed on the top surface of the horizontal end of the L-shaped bracket, and a bending head is fixedly installed on the output end of the cylinder. Both the cylinder and the electric telescopic rod are electrically connected to the PLC controller.

[0011] The effect achieved by the above components is that the distance between the two placement rollers can be flexibly adjusted by using the linkage structure of the electric telescopic rod and the hinge plate, which can be adapted to the processing of bolt bars of different lengths. This solves the limitation of traditional bending machines that can only process bolts of a single specification due to the fixed spacing of the placement seats, and greatly improves the versatility of the equipment.

[0012] Preferably, the inner wall surfaces on both sides of the storage box are provided with a partition device, the partition device including slots opened on the inner wall surfaces on both sides of the storage box, and a partition is slidably inserted between the two slots.

[0013] Preferably, the top surface of the partition is provided with a groove, a movable plate is slidably connected inside the groove, a plug rod is fixedly installed on the surface of the movable plate, and one of the slots has a plug hole on one side of its inner wall surface that matches the plug rod.

[0014] Preferably, a rectangular plate is fixedly installed on the top surface of the partition, and a spring is fixedly installed between the rectangular plate and the movable plate.

[0015] The effect achieved by the above components is that the storage box is divided into two independent chambers by the partition, which can store the bolts to be processed and the processed bolts respectively. This solves the problem of time-consuming material picking and sorting caused by mixed storage of bolts in traditional equipment, and makes the processing flow more orderly.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] In this invention, by setting an adjustment device, the distance between the two placement rollers can be flexibly adjusted by using the linkage structure of the electric telescopic rod and the hinge plate, which can adapt to the processing of bolts of different lengths. This solves the limitation of traditional bending machines that can only process bolts of a single specification due to the fixed spacing of the placement seats, and greatly improves the versatility of the equipment.

The bending head 7 has an arc of R10-R50mm and a hardness ≥HRC50.

[0024] Reference Figure 1-2As shown in this embodiment: The surface of the base 1 is provided with an adjustment device 2. The adjustment device 2 includes two vertical plates 201 fixedly installed on the surface of the base 1. A slide rod 202 is fixedly installed between the two vertical plates 201. Two sliding seats 203 are slidably connected to the outer wall surface of the slide rod 202. U-shaped frames 204 are fixedly installed on the sides of both sliding seats 203. Round rods 205 are fixedly installed on the inner wall surfaces of the vertical ends of both sides of the two U-shaped frames 204. A placement roller 206 is fixedly installed between the two round rods 205. An annular groove is formed on the annular side wall of the placement roller 206. An L-shaped bracket 207 is fixedly installed on the surface of the base 1. A vertical groove 208 is formed on the inner wall surface of the vertical end of the L-shaped bracket 207. A T-shaped plate 209 is slidably connected inside the vertical groove 208. Two hinge plates 210 are hinged to the bottom surface of the T-shaped plate 209. The end of the connecting plate 210 away from the T-shaped plate 209 is hinged to the sliding seat 203. An electric telescopic rod 211 is fixedly installed on the top surface of the horizontal end of the L-shaped bracket 207. The output end of the electric telescopic rod 211 is fixedly connected to the T-shaped plate 209. The clearance between the sliding seat 203 and the sliding rod 202 is ≤0.2mm, and the sliding resistance is ≤5N. The annular groove on the placement roller 206 is 20mm wide and 5mm deep, and is suitable for bolts with a diameter of 5-20mm. The groove width covers different diameter ranges to ensure that the bolts are stable and do not shift when placed. The hinge plate 210 rotates at an angle of 0-60°. The synchronous displacement difference between the two sliding seats 203 is ≤0.3mm. The electric telescopic rod 211 has the following model: DTZ1000-100, a stroke of 100mm, a thrust of 500N, an unloaded speed of 50mm / s, and a response time of ≤0.1s.

[0025] Reference Figure 3-4 As shown in this embodiment: the inner wall surfaces of both sides of the storage box 4 are provided with a partition device 3. The partition device 3 includes slots 31 opened on the inner wall surfaces of both sides of the storage box 4. A partition 32 is slidably inserted between the two slots 31. A groove 33 is opened on the top surface of the partition 32. A movable plate 34 is slidably connected inside the groove 33. A plug rod 35 is fixedly installed on the surface of the movable plate 34. A plug hole 36 matching the plug rod 35 is opened on one side of the inner wall surface of one of the slots 31. A rectangular plate 37 is fixedly installed on the top surface of the partition 32. A spring 38 is fixedly installed between the rectangular plate 37 and the movable plate 34. The partition 32 divides the storage box into two chambers. The left chamber holds the bolt bar to be processed, and the right chamber holds the processed bolt bar. The spring 38 has a diameter of 3mm, an elastic coefficient of 3N / cm, and a compression stroke of 10mm.

[0026] Working principle: When using this device, first check whether the base 1 is stable, whether the surface of the slide bar 202 is smooth and free of impurities, whether the annular groove of the placement roller 206 is clean, and whether the connection between the electric telescopic rod 211, the cylinder 6 and the PLC controller 8 is normal, ensuring that all components operate smoothly. Then, the operator first places the storage box 4 in the designated position on the base 1, and then slides the movable plate 34 on the top of the partition 32, so that the movable plate 34 slides in the groove 33 along the direction of the rectangular plate 37. At this time, the movable plate 34 will compress the spring 38, causing it to be compressed, and at the same time, it will drive the insertion rod 35 to move away from the slot 31. When the insertion rod 35 moves to the appropriate position, align the partition 32 with the slots 31 on both sides of the storage box 4, and flatten it. Insert the rod 35 firmly to the bottom, then release the moving plate 34. Use the rebound force of the spring 38 to push the moving plate 34 back to its original position, allowing the insertion rod 35 to re-insert into the corresponding insertion hole 36, and firmly lock the partition 32. At this time, the storage box 4 is divided into two chambers. The left side is used to place the bolt rod 5 to be processed, and the right side is used to store the bent bolt rod 5. Then, according to the length of the bolt rod 5 to be processed, input the required size through the operation interface of the PLC controller 8, such as 150mm. Then, the PLC controller 8 sends a command to the electric telescopic rod 211 to control its output end to extend or retract: if the spacing needs to be increased, the electric telescopic rod 211 shortens, causing the T-shaped plate 209 to slide upward along the vertical groove 208 of the L-shaped bracket 207. The two hinge plates 210 of the part rotate accordingly, pushing the two sliding seats 203 to move away from each other along the slide rod 202; if the gap needs to be reduced, the electric telescopic rod 211 extends, the T-shaped plate 209 slides downward, and the hinge plates 210 pull the sliding seats 203 closer to the center. When the gap between the two placement rollers 206 reaches the set value error ≤0.3mm, the PLC controller 8 sends a stop signal, and the electric telescopic rod 211 stops moving. At this time, the sliding seat 203 remains horizontal and stable due to the guiding effect of the slide rod 202, ensuring the subsequent bending accuracy. Then, the bolt rod 5 to be processed is taken out from the left cavity of the storage box 4 and placed smoothly into the annular groove of the placement roller 206, which is 20mm wide. The annular groove will form a limit on the bolt rod 5. To prevent the bolt rod 5 from shifting left or right during bending (with a deviation ≤ 0.5mm), after confirming that the bolt rod 5 is securely placed, the bending program is started via the PLC controller 8. The PLC controller 8 sends a signal to the cylinder 6, controlling its output end to extend, driving the bending head 7 to move vertically downward to the middle position of the bolt rod 5. At this time, the cylinder 6 pushes the bending head 7 with a working pressure of 0.6MPa to apply pressure to the bolt rod 5, bending it into a U-shaped structure with a bending angle of 90°±0.5°. After bending is completed, the PLC controller 8 controls the output end of the cylinder 6 to retract, and the bending head 7 returns to its initial position. The operator can then remove the bent bolt rod 5 and place it into the right cavity of the storage box 4 for temporary storage.If bolt bars 5 of different lengths need to be processed, repeat the steps from "adjusting the spacing of the placement rollers 206" to "storage". The parameters can be quickly adjusted by the PLC controller 8 to achieve continuous processing. Through the above process, the device can achieve precise adjustment of the spacing of the placement rollers 206 by means of the coordinated action of the electric telescopic rod 211 and the PLC controller 8. With the positioning function of the annular groove and the classification design of the storage box 4, it not only meets the bending requirements of bolt bars of different lengths, but also improves processing efficiency and ease of operation.
