Description

Technical Field

[0001] This utility model relates to the technical field of Ma Wang nail bending equipment, and in particular to a bending equipment for manufacturing Ma Wang nails. Background Technology

[0002] Ma Wang nail, also known as leech nail, refers to a nail with two legs. Ma Wang nail adopts a U-shaped integrated structure, with two threaded pointed legs forming the main frame. The spacing between the legs can be adjusted according to the application scenario. Some products are galvanized and have a silver-white luster. They are mainly used in the fields of fixing wooden beams in buildings, mine track accessories, and ship structure reinforcement.

[0003] Traditionally, the production of King Bar nails uses round steel or threaded steel of suitable nominal diameter as the base material. After grinding both ends to a pointed shape, a thread rolling process is performed to create continuous raised patterns on the surface to enhance friction. The material is then transported to a bending machine. This bending machine typically uses two sets of opposing mating blocks within a support frame, forming a U-shaped gap between them. One set of blocks is fixed, while the other set is moved closer to or away from the fixed block by a hydraulic cylinder. The base material is bent by compression. Workers place the threaded base material one by one into the machine, and then bend it into a King Bar nail using the two sets of mating blocks. After bending, the King Bar nail is removed and replaced with a new base material.

[0004] However, the gaps formed are fixed, and each time different sizes of horse king nails need to be made, the entire machine must be stopped and the power cut off. Personnel must replace the new mating blocks on the support to adapt them. The manual replacement is time-consuming and laborious, which affects the production efficiency of horse king nails to a certain extent. Utility Model Content

[0026] like Figures 1 to 8 As shown, a bending device for making Ma Wang nails includes a support 1 and two upright plates 4 mounted opposite each other. Turntable 1 5 and turntable 2 6 are rotatably mounted on opposite sides of the two sets of upright plates 4. Turntable 1 5 is rotatably mounted on the upright plate 4 at the right end, and turntable 2 6 is rotatably mounted on the upright plate 4 at the left end. A cuboid fixing block 3 is mounted on turntable 1 5, and a U-shaped pressing block 2 is mounted on turntable 2 6. Several sets of fixing blocks 3 and pressing blocks 2 are provided, each arranged along the circumference of turntable 1 5 and turntable 2 6, and the fixing blocks 3 and pressing blocks 2 are arranged opposite each other. In this embodiment, the size of each set of fixing blocks 3 and pressing blocks 2 can be adjusted and changed according to the actual use by the personnel.

[0027] Several sets of through holes 7 are provided on the turntable 2 6, each set of through holes 7 is opposite to several sets of pressure blocks 2. A support plate 8 is provided between the turntable 2 6 and the pressure blocks 2. The pressure blocks 2 are screwed and fixed to the support plate 8. An expansion cylinder 9 is horizontally provided on the side of the support plate 8 away from the pressure blocks 2 and passes through the through holes 7. The expansion cylinder 9 is slidably connected to the through holes 7. A pusher 10 is provided on the vertical plate 4 connected to the turntable 2. In this embodiment, the pusher 10 is a hydraulic cylinder. A push rod 11 is provided at the top of the piston rod of the pusher 10. The push rod 11 is opposite to the through holes 7. The support plate 8 is on the side away from the pressure blocks 2. A sliding cylinder 12 parallel to the expansion cylinder 9 is provided. A first groove 13 is provided on the turntable 2 6. One end of the sliding cylinder 12 is slidably connected to the first groove 13. A telescopic spring 14 is provided inside the sliding cylinder 12 and connected to the inner wall of the first groove 13. A second groove 15 is provided on the inner wall of the through hole 7. A locking block 16 is slidably provided at the second groove 15. A through hole 17 is provided on the expansion cylinder 9 for the locking block 16 to be inserted and engaged. A second telescopic spring 18 is provided inside the second groove 15 and connected to the end of the locking block 16 located inside the second groove 15. A guide block 30 is also provided on the top of the piston rod of the pusher 10. Figures 3 to 4As shown, the side of the locking block 16 away from the sliding groove 15 is inclined downward from left to right to form an inclined surface 19. The front end of the guide block 30 is provided with a guide surface 20 that slides and engages with the inclined surface 19 of the locking block 16. A sliding groove is provided on the outer wall of the guide block 30. A top block 22 is slidably provided at the sliding groove. The top block 22 is slidably connected to the sliding groove 21 through a telescopic spring 23. Inclined surfaces 24 are provided at both ends of the side of the top block 22 away from the sliding groove 21. The length and width of the top block 22 are smaller than the length and width of the through hole 17.

[0028] A motor 25 is installed on the outer side of the upright plate 4 on which the turntable 2 6 is rotatably mounted. The output shaft of the motor 25 is connected to a linkage rod 26, which is located between the two sets of upright plates 4. Driven wheels 27 are fitted on the outer walls of both the first turntable 5 and the second turntable 6. Driven wheels 28 are fitted on the linkage rod 26. The two sets of drive wheels 28 mesh with the driven wheels 27 on the first turntable 5 and the second turntable 6, respectively. Several sets of positioning plates 29 are arranged on the first turntable 5 along the circumference of the first turntable 5. Each set of positioning plates 29 is opposite to each set of fixing blocks 3. The distance between the positioning plates 29 and the fixing blocks 3 varies depending on the length of the fixing blocks 3. The purpose of this is to ensure that the center of the substrate is located between the fixing blocks 3 and the pressure blocks 2.

[0029] When personnel do not perform bending work on the substrate, such as Figure 1 As shown, the operator can position themselves in front of the support 1 and then place the substrate between the fixing block 3 and the pressure block 2 located in front of turntable 5 and turntable 6, as shown. Figure 3 and Figure 4 As shown, the pressure block 2, located in front of turntable 5 and turntable 6, has a through hole 17 in the expansion cylinder 9 on one side that engages with the locking block 16 in the through hole 7. Then, the pusher 10 is activated, and the piston rod of the pusher 10 extends into the expansion cylinder 9. The guide block 30 pushes the locking block 16 back into the slide groove 15, compressing the telescopic spring 18. Then, the guide block 30 continues to move forward, making the top block 22 face the locking block 16. The telescopic spring 23 begins to extend, pushing the top block 22. The top block 22 contacts the locking block 16, pushing it away from the through hole 17 and moving it into the slide groove 15. It should be noted that the telescopic spring 23 uses a telescopic force... The degree is greater than that of the extension spring 18. At this time, the top block 22 is located in the through hole 17 but has not yet entered the slide groove 15. The pusher 10 continues to drive the piston rod to extend. At this time, the push rod 11 contacts the support plate 8. Under the sliding cooperation of the sliding cylinder 12 and the slide groove 13, the support plate 8 moves horizontally away from the turntable 6 and toward the fixed block 3. Then, the base material on the fixed block 3 is bent. It should be noted that when multiple bending operations are required, the pusher 10 will not completely return during the return process. The locking block 16 will be blocked by the outer wall of the expansion cylinder 9 in the through hole 7 in the slide groove 15, so that the through hole 17 on the expansion cylinder 9 will not be inserted with the locking block 16.

[0030] When it is necessary to replace the fixing block 3 and pressure block 2 with other specifications, first control the pusher 10 to move back completely, so that the through hole 17 on the expansion cylinder 9 is aligned with the locking block 16. Then, the guide block 30 is driven to continue to move out of the expansion cylinder 9. Since the top block 22 has two inclined surfaces 24, during the retraction process, the top block 22 will contact the edge of the through hole 17 and be pressed down. After the guide block 30 is separated from the expansion cylinder 9, the telescopic spring 18 begins to extend, pushing the locking block 16 to engage with the through hole 17. Then, the motor 25 starts to rotate forward. The motor 25 is activated by driving the driven wheel 27 to rotate via the drive wheel 28. The drive wheel 26 connects the turntable 5 and the turntable 6 to rotate synchronously. When the fixed block 3 and the pressure block 2 of the appropriate size rotate to the front of the bracket 1, the motor 25 stops. It should be noted that the support plate 8 and the expansion tube 9 connected to each set of pressure blocks 2 are of the same size. After the turntable 5 stops rotating, the pusher 10 begins to extend and enters the expansion tube 9, pushing the locking block 16 away from the through hole 17. Then, the pressure block 2 and the corresponding fixed block 3 cooperate to perform a bending operation.

[0031] 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.
