Technical Field
[0001] This utility model relates to the technical field of chain production equipment, and in particular to a chain outer link pressing tool. Background Technology
[0002] Conveyor chains are widely used as a traction component in conveying equipment. They are one of the most widely used chains in the conveyor industry, and have advantages such as the versatility of conveyed items, adaptability to working environments, accuracy of conveying position, controllable cycle time, long conveying distance, and ability to withstand heavy loads and impacts.
[0003] Traditional chains consist of inner and outer links. Two sleeves pass through two rollers and are fixed to two inner links to form an inner link. The outer link is mainly composed of an outer link and a pin. In the existing technology, the press-fitting fixture for the outer link is generally fixed on the lower die of the punch press, with the upper die of the punch press above it. Manual loading and unloading are both within the range of the upper die, which poses a safety hazard of the upper die pressing down when loading and unloading manually. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art by proposing a chain external link pressing tool that can improve production safety and is easy to operate.
[0005] To achieve the above objectives, this utility model proposes a chain external link pressing fixture, including a base, a cylinder I, a slide, a fixture mold, and a hand-operated valve. The base is provided with the cylinder I, the slide, and the hand-operated valve. The cylinder I drives the slide to reciprocate. The two air ports of the cylinder I are connected to the two air outlets of the hand-operated valve through two air pipes, respectively. The air inlet of the hand-operated valve is connected to the air supply pipe. The slide is provided with the fixture mold.
[0006] Preferably, the tooling mold includes two supports, an upper support plate, a lower support plate, and two upper through holes. Two supports are provided between the lower support plate and the upper support plate, and two upper through holes are provided on the upper support plate. Each support is provided with a clearance groove corresponding to the upper through hole above it.
[0007] Preferably, a spring fixing plate is provided between the lower support plate and the slide block. The spring fixing plate has two receiving grooves, each containing a spring. Each spring has a top pin at its upper end. The lower support plate has lower through holes that correspond to and match the top pins. The lower through holes correspond to the upper through holes.
[0008] Preferably, the lower support plate has a cylinder II in the middle, and the upper support plate has a hole for the piston rod of the cylinder II to extend out.
[0009] Preferably, the piston rod of the cylinder I is provided with a push block, the push block is provided with a connector, and the slide is provided with a slot that mates with the connector.
[0010] Preferably, the base is provided with two positioning bodies, one in the front and one in the back, and the inner side of each positioning body is provided with a sliding groove that cooperates with the slide.
[0011] The beneficial effects of this utility model are as follows: This utility model has a base equipped with a cylinder I, a slide, and a hand valve. The cylinder I drives the slide to reciprocate. The two air ports of the cylinder I are connected to the two air outlets of the hand valve through two air pipes. The air inlet of the hand valve is connected to the air supply pipe. The slide is equipped with a tooling mold. When loading and unloading, the cylinder I is extended by controlling the hand valve to remove the tooling mold from under the upper die seat of the punch press. After loading is completed, the cylinder I is retracted by controlling the hand valve to bring the tooling mold under the pressure block on the upper die seat. Compared with the prior art, this utility model can improve production safety and is easy to operate.

Detailed Implementation
[0017] See Figure 1 , Figure 2 and Figure 3This utility model discloses a chain external link pressing tooling, including a base 1, a cylinder I2, a slide 3, a tooling mold 4, and a manual valve 5. The base 1 is provided with the cylinder I2, the slide 3, and the manual valve 5. The cylinder I2 drives the slide 3 to reciprocate. The two air ports 8 of the cylinder I2 are connected to the two air outlets of the manual valve 5 through two air pipes 6 respectively. The air inlet of the manual valve 5 is connected to the air supply pipe 7. The tooling mold 4 is provided on the slide 3.
[0018] The tooling mold 4 includes two supports 41, an upper support plate 42, a lower support plate 43, and two upper through holes 44. The lower support plate 43 and the upper support plate 42 are provided with two supports 41, one in front and one behind. The upper support plate 42 is provided with two upper through holes 44, and each support 41 is provided with a relief groove 45 corresponding to the upper through hole 44 above it.
[0019] A spring fixing plate 8 is provided between the lower support plate 43 and the slide block 3. The spring fixing plate 8 is provided with two receiving grooves 9, and each receiving groove 9 is provided with a spring 10. Each spring 10 is provided with a top pin 11 at its upper end. The lower support plate 43 is provided with a lower through hole 12 that corresponds to and matches the top pin 11. The lower through hole 12 corresponds to the upper through hole 44.
[0020] The lower support plate 43 is provided with a cylinder II 47 in the middle, and the upper support plate 42 is provided with a hole 46 for the piston rod of the cylinder II 47 to extend out.
[0021] The piston rod of the cylinder I2 is provided with a push block 15, the push block 15 is provided with a connector 16, and the slide block 3 is provided with a slot 17 that mates with the connector 16.
[0022] The base 1 is provided with two positioning bodies 13, one in front and one in back, and the inner side of each positioning body 13 is provided with a sliding groove 14 that cooperates with the slide 3.
[0023] The working process of this utility model:
[0024] In the operation of this utility model, a chain link pressing fixture is used. The outer link plate 18 is placed on the upper support plate 42, and then a pin 19 is inserted. The lower end of the pin 19 passes through the corresponding pin hole and upper through hole 44 on the outer link plate 18, then extends into the corresponding clearance groove 45 and rests against the top pin 11. Then, the cylinder I2 is retracted via the hand valve 5. The cylinder I2 pulls the slide block 3 to the right via the push block 15. The slide block 3 drives the fixture mold 4 into the space below the pressing block 20 on the upper mold base 21. Then, the punch press drives the upper... The mold base 21 moves downward, and the upper mold base 21 drives the pressure block 20 to move downward and press down the pin 19, pressing the interference section of the pin 19 that fixes the outer link plate into the pin hole. After the pressing is completed, the punch press drives the upper mold base 21 to move upward and return to its original position. Then, the cylinder I2 is extended and put into operation by the hand valve 5. The cylinder I2 pushes the tooling mold 4 to be removed from below the upper mold base 21. Then the pressed outer link is removed. When the force of the spring 10 cannot lift the outer link, the cylinder II 47 can be activated to extend and lift the pressed outer link.
[0025] The push block 15 and the slide block 3 are connected by the joint 16 and the slot 17, so as to avoid problems such as the slide block 3 not sliding smoothly in the slide groove 14 and the slide block 3 not fitting properly with the base 1 due to assembly errors.
[0026] 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.
