Description

Technical Field

[0001] This utility model relates to the field of locking plate forming, and in particular to a tooling for two-stage forming of moving leaf locking plates. Background Technology

[0002] The locking plate of the moving leaf lock is formed once during the processing to obtain the required size profile and hole. In order to obtain the final shape of the product, the locking plate needs to be formed twice after the first forming to expand the hole and optimize the hole structure, and improve the internal structure of the hole.

[0003] While existing forming fixtures can complete the hole enlargement operation by pressing the upper and lower mold bases together, there are other problems in their use. For example, only one hole can be processed at a time, and there is only one upper and one lower mold base. However, two holes need to be enlarged and optimized on a single locking piece. After forming a single hole, the locking piece needs to be picked up and turned around to process the other hole, which reduces the processing efficiency of the locking piece. Moreover, it is not convenient to replace the positioning shaft. After repeated use, the surface of the positioning shaft will wear down. When the wear is severe, it will be difficult to place the locking piece down to the bottom. When replacing the positioning shaft, the fixing screws need to be removed with the help of tools, which is time-consuming and laborious. In order to solve the above problems, we propose a two-stage forming forming fixture for moving leaf locking pieces. Utility Model Content

[0004] The purpose of this invention is to provide a two-stage forming and pressing tooling for moving leaf lock plates, which solves the problem that existing forming and pressing tooling can only perform forming and pressing on a single hole at a time and is not convenient for quick replacement of the positioning shaft.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a two-stage forming and pressing tooling for a moving blade locking piece, comprising a base plate and a stamping mechanism, wherein a first fixing frame is bolted to the top of the base plate, a second fixing frame is provided on the top of the first fixing frame, and a bidirectional screw is rotatably connected inside both the first fixing frame and the second fixing frame, and two first screw plates and a second screw plate are respectively threaded to the surfaces of the two bidirectional screws, and a lower die base and an upper die base are respectively installed on the other side of the first screw plate and the second screw plate, wherein a positioning shaft is placed inside the upper die base, and an installation groove is opened on the surface of the upper die base, a connecting block is provided inside the installation groove, a limit pin is installed on one side of the connecting block, a baffle is bolted to the inside of the installation groove, and a limit spring is installed between the other side of the connecting block and the baffle.

[0006] The above technical solution can improve the processing efficiency of locking plates, can be appropriately adjusted according to the length of the locking plate profile, has high practicality, facilitates quick replacement of the positioning shaft, is simple and labor-saving to operate, reduces the burden of personnel replacement, and has good flexibility.

[0007] The present invention is further configured such that: the stamping mechanism includes a top plate, the top plate is disposed on the top of the second fixed frame, support rods are installed at equal intervals between the top of the top plate and the bottom plate, a hydraulic cylinder is bolted through the top of the top plate, and the output end of the hydraulic cylinder is connected to the top of the second fixed frame.

[0008] By adopting the above technical solution, the top plate, support rod and hydraulic cylinder can provide power for the downward pressing of the second fixed frame.

[0009] The present invention is further configured such that: a guide rod is provided through the front of both the first screw plate and the second screw plate, and the two ends of the two guide rods are respectively welded to the interior of the first fixing frame and the second fixing frame.

[0010] By adopting the above technical solution, the guide rod can limit the movement of the first and second screw plates, preventing them from flipping over during their forward and backward movement.

[0011] The present invention is further configured such that a first throttle and a second throttle are respectively installed at the other end of the two bidirectional screws.

[0012] By adopting the above technical solution, the setting of the first and second rotary handles makes it easy for personnel to rotate the bidirectional screws in the first and second fixed frames.

[0013] The present invention is further configured such that: a mounting hole is provided on the top of the base plate.

[0014] By adopting the above technical solution, the installation holes make it easy for personnel to fix the base plate to the platform with screws.

[0015] The present invention is further configured such that a retainer that engages with the positioning shaft is installed inside the upper mold base.

[0016] By adopting the above technical solution, the positioning shaft can be limited by the setting of the clamping seat, so as to prevent the positioning shaft from shaking and shifting inside the lower mold base.

[0017] The present invention is further configured such that: a fixing rod is welded to the other side of the connecting block, and the other end of the fixing rod extends through to the outside of the baffle and is fitted with a pull plate.

[0018] By adopting the above technical solution, the setting of the fixing rod and the pull plate makes it easy for personnel to pull the connecting block outward, thereby causing the limit pin to separate from the limit hole in the positioning shaft.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model first measures the distance between the two holes of the locking plate, then holds the first throttle to drive the bidirectional screw to rotate. When the bidirectional screw rotates, it will drive the first screw plate and the lower mold base to move outward synchronously. When the lower mold base moves, it will drive the positioning shaft to move together until the two through holes on the locking plate can slide into the two positioning shafts. Then, the distance between the two upper mold bases is adjusted in the same way. Finally, the hydraulic cylinder is started to drive the second fixed frame and the upper mold base to press down. This can improve the processing efficiency of the locking plate. It can be appropriately adjusted according to the length of the locking plate profile and has high practicality.

[0021] 2. This utility model allows one hand to grasp the pull plate and pull it outward. When the pull plate is pulled outward, the connecting block will move outward due to the fixing rod. When the connecting block moves outward, it will not only compress the limit spring and cause it to contract and deform, but also cause the limit pin to separate from the limit hole in the positioning shaft. When the pull plate is pulled out to the end, the positioning shaft can be directly pulled out with the other hand. This makes it easy to quickly replace the positioning shaft. The operation is simple and labor-saving, reduces the burden of personnel replacement, and has good flexibility. Attached Figure Description

[0028] Example 1:

[0029] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A two-stage forming and pressing fixture for a moving leaf lock plate includes a base plate 1 and a stamping mechanism 10. A first fixing frame 2 is bolted to the top of the base plate 1, and a second fixing frame 3 is provided on the top of the first fixing frame 2. Both the first fixing frame 2 and the second fixing frame 3 are rotatably connected to a bidirectional screw 4. The surfaces of the two bidirectional screws 4 are respectively threaded with two first screw plates 5 and two screw plates 6. A lower die base 7 and an upper die base 8 are respectively installed on the other side of the first screw plates 5 and the second screw plates 6. A positioning shaft 9 is placed inside the upper die base 8. The positioning shaft 9 is formed by first measuring the distance between the two holes of the lock plate. Adjust the distance between the two upper mold bases 8 in the same way. Then, hold the first throttle 16 to rotate the double-sided screw 4. When the double-sided screw 4 rotates, it will drive the first screw plate 5 and the lower mold base 7 to move outward synchronously. When the lower mold base 7 moves, it will drive the positioning shaft 9 to move together until the two through holes on the locking plate can slide into the two positioning shafts 9. Then, adjust the distance between the two upper mold bases 8 in the same way. Finally, start the hydraulic cylinder 103 to drive the second fixed frame 3 and the upper mold base 8 to press down. This can improve the processing efficiency of the locking plate. It can be adjusted appropriately according to the length of the locking plate profile and has high practicality.

[0030] refer to Figure 1 and Figure 2 The stamping mechanism 10 includes a top plate 101, which is disposed on the top of the second fixed frame 3. Support rods 102 are installed at equal intervals between the top of the top plate 101 and the bottom plate 1. A hydraulic cylinder 103 is bolted through the top of the top plate 101. The output end of the hydraulic cylinder 103 is connected to the top of the second fixed frame 3. Through the arrangement of the top plate 101, support rods 102 and hydraulic cylinder 103, power can be provided for the downward pressing of the second fixed frame 3.

[0031] refer to Figure 3 Guide rods 15 are provided through the front of both the first screw plate 5 and the second screw plate 6. The two ends of the two guide rods 15 are welded to the inside of the first fixed frame 2 and the second fixed frame 3 respectively. By setting the guide rods 15, the first screw plate 5 and the second screw plate 6 can be limited to prevent the first screw plate 5 and the second screw plate 6 from flipping over during the back and forth movement.

[0032] refer to Figure 1 and Figure 3 The other ends of the two bidirectional screws 4 are respectively equipped with a first throttle 16 and a second throttle 17. The setting of the first throttle 16 and the second throttle 17 makes it easy for personnel to rotate the bidirectional screws 4 in the first fixed frame 2 and the second fixed frame 3.

[0033] refer to Figure 1 The top of the base plate 1 is provided with mounting holes 18, which allows personnel to easily fix the base plate 1 to the platform with screws.

[0034] Brief description of the usage process: First, measure the distance between the two holes of the locking plate. Then, hold the first throttle 16 to drive the bidirectional screw 4 to rotate. When the bidirectional screw 4 rotates, it will drive the first screw plate 5 and the lower mold base 7 to move outward synchronously. When the lower mold base 7 moves, it will drive the positioning shaft 9 to move together until the two through holes on the locking plate can slide into the two positioning shafts 9. Then, adjust the distance between the two upper mold bases 8 in the same way. Finally, start the hydraulic cylinder 103 to drive the second fixed frame 3 and the upper mold base 8 to press down.

[0035] Example 2:

[0036] refer to Figure 1 , Figure 2 and Figure 4 A two-stage forming and pressing tooling for a moving leaf lock plate is provided. The surface of the upper mold base 8 is provided with an installation groove 22. A connecting block 11 is provided inside the installation groove 22. A limit pin 12 is installed on one side of the connecting block 11. A baffle 13 is bolted inside the installation groove 22. A limit spring 14 is installed between the other side of the connecting block 11 and the baffle 13. By grasping the pull plate 21 with one hand and pulling it outward, the pull plate 21 will move the connecting block 11 outward under the fixation of the fixing rod 20. When the connecting block 11 moves outward, it will not only compress the limit spring 14 and cause it to contract and deform, but also cause the limit pin 12 to separate from the limit hole in the positioning shaft 9. When the pull plate 21 is pulled out to the bottom, the positioning shaft 9 can be directly pulled out with the other hand. This allows for quick and easy replacement of the positioning shaft 9. The operation is simple and labor-saving, reduces the burden of personnel replacement, and has good flexibility.

[0037] refer to Figure 4 The upper mold base 8 has a retainer 19 installed inside, which engages with the positioning shaft 9. The retainer 19 can limit the positioning shaft 9 and prevent it from shaking or shifting inside the lower mold base 7.

[0038] refer to Figure 2 and Figure 4 A fixing rod 20 is welded to the other side of the connecting block 11. The other end of the fixing rod 20 extends through the outside of the baffle 13 and is fitted with a pull plate 21. With the fixing rod 20 and the pull plate 21, it is easy for personnel to pull the connecting block 11 outward, thereby causing the limit pin 12 to separate from the limit hole in the positioning shaft 9.

[0039] Brief description of the usage process: By grasping the pull plate 21 with one hand and pulling it outward, the pull plate 21 will move the connecting block 11 outward under the fixation of the fixing rod 20. When the connecting block 11 moves outward, it will not only compress the limit spring 14 to cause it to contract and deform, but also cause the limit pin 12 to separate from the limit hole in the positioning shaft 9. When the pull plate 21 is pulled out to the end, the positioning shaft 9 can be pulled out directly with the other hand.
