Description

Technical Field

[0001] The utility model relates to the field of workpiece pressing, in particular to a pressing tooling. Background Art

[0002] The pressing tooling refers to a general term for equipment that extrudes workpieces. The working principle of the pressing tooling is relatively simple. Generally, an air cylinder is used as a driving part, and an extrusion seat is used to extrude the workpiece to complete the extrusion processing work of the workpiece.

[0003] When producing and processing bottle caps, since bottle caps usually consist of an inner and outer layer of the cap and the stopper, when pressing the bottle cap, the stopper is extruded into the cap to improve the sealing performance of the cap with the stopper. This type of pressing tooling usually has the advantages of simple structure, convenient operation, and easy maintenance.

[0004] In the process of using the existing pressing tooling, in order to improve the stability of workpiece pressing, a clamping mechanism is usually added to clamp and fix the workpiece. However, the clamping mechanism generally clamps the outside of the workpiece. When pressing the bottle cap and the stopper, the components of the clamping mechanism are likely to obstruct the pressing of the bottle cap and the stopper, resulting in the inability to smoothly press the stopper into the cap.

[0005] Therefore, it is necessary to provide a new pressing tooling to solve the above technical problems. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides a pressing tooling.

[0007] The pressing tooling provided by the utility model includes a base, a fixed frame is fixedly connected to the base, and an air cylinder is fixedly connected to the fixed frame. The bottom end of the output end of the air cylinder is fixedly connected with a pressing seat. An installation groove is provided at the bottom of the pressing seat, and a pressing column is slidably connected in the installation groove. Limiting holes communicating with the installation groove are provided on both sides of the pressing seat, and limiting rods are slidably connected in the limiting holes.

[0008] Preferably, inclined surfaces are provided at both the top and bottom of the pressing column, and a spring A is fixedly connected between the top of the pressing column and the inner top wall of the installation groove.

[0009] Preferably, springs B are sleeved on the limiting rods. One end of each spring B is fixedly connected to the inner wall of the limiting hole, and the other end of the spring B is fixedly connected to the limiting rod.

[0010] Preferably, a storage hole is provided on the base, and fixing grooves are provided on both inner walls of the storage hole.

[0011] Preferably, a shaft rod is rotatably connected in each of the fixed grooves, and a limiting plate is fixedly connected between the shaft rods. A spiral spring is fixedly connected between the shaft rod and the inner wall of the fixed groove on the same side.

[0012] Preferably, one side of the top of the limiting plate is fixedly connected with a mounting bracket, and a mounting plate is rotatably connected to the mounting bracket. A limiting groove is provided at the top of the mounting plate, and a damping piece is provided at the connection between the mounting bracket and the mounting plate.

[0013] Preferably, a connecting bracket is rotatably connected to the side of the top of the limiting plate away from the mounting bracket, and the top end of the connecting bracket is fixedly connected to the output rod of the air cylinder through a metal ring.

[0014] Compared with the related art, the pressing tool provided by the present utility model has the following beneficial effects:

[0015] 1. In the present utility model, the pressing seat is inserted into the bottle stopper. After the pressing seat enters the bottle stopper, the pressing seat cooperates with the inner bottom wall of the bottle stopper to squeeze the extrusion column and the spring A, so that the extrusion column contracts into the installation groove. At this time, the extrusion column can be used to squeeze the limiting rod, so that the limiting rod extends out of the limiting hole, and the inner wall of the bottle stopper is squeezed by the two limiting rods, thereby fixing the bottle stopper and improving the stability of the device when pressing the bottle cap and bottle stopper.

[0016] 2. When the air cylinder extends to perform the pressing work in the present utility model, the output rod of the air cylinder can press the limiting plate through the connecting bracket, so that the other end of the limiting plate tilts up. After the other end of the limiting plate tilts up, it can drive the mounting plate to lift. At this time, the output rod of the air cylinder moves downward, while the mounting plate lifts upward, which can improve the working efficiency of the device for pressing the workpiece.

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0024] Please refer to Figures 1 to 4 , a pressing tooling provided by an embodiment of the present utility model includes a base 1, a fixing frame 11 is fixedly connected to the base 1, and a pneumatic cylinder 12 is fixedly connected to the fixing frame 11. A receiving hole 13 is provided on the base 1, and fixing grooves 14 are provided on both inner walls of the receiving hole 13.

[0025] It should be noted that: the area of the base 1 is relatively large, which can provide high stability during the pressing operation. During the pressing operation, the bottle cap and the bottle stopper are placed on the mounting plate 41, and then the pneumatic cylinder 12 is controlled to extend. Using the thrust of the pneumatic cylinder 12, the bottle stopper is squeezed into the bottle cap by the pressing seat 2.

[0026] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 3 , the bottom end of the output end of the pneumatic cylinder 12 is fixedly connected to a pressing seat 2. An installation groove 21 is provided at the bottom of the pressing seat 2. A pressing column 23 is slidably connected in the installation groove 21. Limiting holes 24 communicating with the installation groove 21 are provided on both sides of the pressing seat 2. Limiting rods 25 are slidably connected in the limiting holes 24. Inclined surfaces are provided at the top and bottom of the pressing column 23. A spring A 22 is fixedly connected between the top of the pressing column 23 and the inner top wall of the installation groove 21. Springs B 26 are sleeved on the limiting rods 25. One end of the spring B 26 is fixedly connected to the inner wall of the limiting hole 24, and the other end of the spring B 26 is fixedly connected to the limiting rod 25.

[0027] It should be noted that when pressing down the bottle stopper and the bottle cap, the pressing seat 2 is inserted into the bottle stopper. At this time, as the air cylinder 12 continuously extends, the pressing seat 2 cooperates with the bottle stopper, and can squeeze the extrusion column 23 and the spring A22, causing the spring A22 to contract, so that the extrusion column 23 contracts into the installation groove 21. At this time, after the extrusion column 23 enters the installation groove 21, the inclined surface and the outer wall at the top of the extrusion column 23 will squeeze the limiting rod 25, causing the limiting rod 25 to extend out of the limiting hole 24. At the same time, the spring B26 will contract. At this time, the end of the extended limiting rod 25 will abut against the inner wall of the bottle stopper, and the bottle stopper is fixed by the two limiting rods 25. When the pressing work is completed, the bottle cap is manually fixed, and then the air cylinder 12 is controlled to contract. At this time, the output rod of the air cylinder 12 will drive the pressing seat 2 to rise, so that the pressing seat 2 is withdrawn from the bottle stopper. At this time, the spring A22 rebounds, driving the extrusion column 23 to extend out of the installation groove 21. At this time, the limit of the limiting rod 25 by the extrusion column 23 disappears, and the spring B26 begins to rebound, driving the limiting rod 25 to retract into the limiting hole 24 again. At this time, the extrusion of the bottle stopper by the limiting rod 25 disappears, and the pressed bottle cap can be taken away to prepare for the pressing work of the next bottle cap.

[0028] In the embodiment of the present invention, please refer to Figure 1 and Figure 4 , a shaft rod 31 is rotatably connected in each of the fixing grooves 14, and a limiting plate 3 is fixedly connected between the shaft rods 31. A winding spring 32 is fixedly connected between the shaft rod 31 and the inner wall of the fixing groove 14 on the same side. One side of the top of the limiting plate 3 is fixedly connected with a mounting frame 4, and a mounting plate 41 is rotatably connected to the mounting frame 4. A limiting groove 42 is provided at the top of the mounting plate 41. A damping sheet is provided at the connection between the mounting frame 4 and the mounting plate 41;

[0029] A connecting frame 5 is rotatably connected to the side of the top of the limiting plate 3 away from the mounting frame 4, and the top end of the connecting frame 5 is fixedly connected with the output rod of the air cylinder 12 through a metal ring.

[0030] It should be noted that the mounting plate 41 is a solid structure. When performing the pressing work, the bottle cap is placed on the mounting plate 41, and the bottle stopper is placed on the bottle cap. Then, when the air cylinder 12 extends, it can drive the limiting plate 3 to rotate. At this time, the limiting plate 3 tightens the winding spring 32 by means of the shaft rod 31, and one end of the limiting plate 3 close to the mounting frame 4 tilts up. When the limiting plate 3 rotates, the mounting plate 41 can rotate by itself relying on the weight of the bottom of the solid body, so that its limiting groove 42 is always facing up. During this process, the descending pressing seat 2 cooperates with the ascending mounting plate 41, and can squeeze the bottle cap and the bottle stopper faster. When the extrusion is completed, the air cylinder 12 begins to contract. At this time, the winding spring 32 rebounds, driving the limiting plate 3 to rotate in the reverse direction to provide an additional power source, improving the smoothness of the limiting plate 3 when rotating;

[0031] It should also be noted that during the telescoping process of the air cylinder 12, the connecting frame 5 can be used to control the lifting operation of the end of the limiting plate 3 away from the mounting frame 4, thereby completing the rotation operation of the limiting plate 3.

[0032] The working principle of the pressing tooling provided by the present utility model is as follows:

[0033] First, place the base 1 at the designated position, then power on the device, and then the squeezing work of the bottle cap and the bottle stopper can be carried out. First, place the bottle cap in the limiting groove 42 of the mounting plate 41 to make it stable, then place the bottle stopper on the bottle cap, and then control the air cylinder 12 to extend. Using the thrust of the air cylinder 12, the bottle stopper is squeezed into the bottle cap by the pressing seat 2. As the air cylinder 12 continues to extend, the pressing seat 2 and the bottle stopper cooperate to squeeze the pressing column 23 and the spring A22, causing the spring A22 to contract, so that the pressing column 23 contracts into the mounting groove 21. At this time, after the pressing column 23 enters the mounting groove 21, the inclined surface and the outer wall at the top of the pressing column 23 will squeeze the limiting rod 25, causing the limiting rod 25 to extend out of the limiting hole 24, and at the same time, the spring B26 will contract. At this time, the end of the extended limiting rod 25 will abut against the inner wall of the bottle stopper, and the bottle stopper is fixed by the two limiting rods 25;

[0034] At the same time, the output rod of the air cylinder 12 will drive the rotating rod of the limiting plate 3 through the connecting frame 5. At this time, the limiting plate 3 tightens the clockwork spring 32 by means of the shaft rod 31, and the end of the limiting plate 3 close to the mounting frame 4 tilts up. When the limiting plate 3 rotates, the mounting plate 41 can rotate by itself relying on the weight of the solid body at the bottom, so that its limiting groove 42 is always facing up. During this process, the descending pressing seat 2 and the ascending mounting plate 41 cooperate to squeeze the bottle cap and the bottle stopper faster;

[0035] When the pressing work is completed, manually fix the bottle cap, and then control the air cylinder 12 to contract. At this time, the output rod of the air cylinder 12 will drive the pressing seat 2 to rise, so that the pressing seat 2 is withdrawn from the bottle stopper. At this time, the spring A22 rebounds, driving the pressing column 23 to extend out of the mounting groove 21. At this time, the limit of the limiting rod 25 by the pressing column 23 disappears, and the spring B26 begins to rebound, driving the limiting rod 25 to retract back into the limiting hole 24 again. At this time, the extrusion of the bottle stopper by the limiting rod 25 disappears, and the pressed bottle cap can be taken away to prepare for the pressing work of the next bottle cap;

[0036] At the same time, during the contraction process of the air cylinder 12, it can use the connecting frame 5 to rotate the limiting plate 3 in the reverse direction, so that the separation between the mounting plate 41 and the pressing seat 2 is faster, and the workpiece can be taken off from the pressing seat 2 faster. Then, it can be prepared for the squeezing work of the next bottle cap and bottle stopper.
