DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1-9, a steam turbine door cover gasket stamping and forming device shown in the figure includes a body 1, a telescopic rod 2 is provided on the body 1, and a sliding plate 3 is installed at the telescopic end of the telescopic rod 2. During stamping, the telescopic rod 2 drives the sliding plate 3 to move, and the sliding plate 3 is connected to the upper template 4. The movement of the sliding plate 3 causes the upper template 4 to move downward to perform stamping on the material, and a support plate 5 is also installed on the body 1. The support plate 5 is fixed to the body 1 by fixing bolts, and a lower template 6 is connected to the support plate 5. The lower template 6 corresponds to the upper template 4, and the upper template 4 and the sliding plate 3 are detachably connected, and the lower template 6 and the support plate 5 are detachably connected, which is convenient for the upper template 4 and the lower template The plate 6 can be disassembled to facilitate the replacement of the upper template 4 and the lower template 6 according to production needs. When the upper template 4 moves down to correspond to the lower template 6, the material is stamped. It also includes: an extrusion component for extruding the material to be stamped on the lower template 6, and the extrusion component is installed on the machine body 1; a flattening component for flattening the material to be stamped on the lower template 6. The flattening component is arranged in conjunction with the extrusion component and is installed inside the machine body 1. After the extrusion component extrude the material through multiple groups of extrusion sheets 11 respectively installed on the two groups of rotating rollers 8, the flattening component drives the two groups of rotating rollers 8 to drive the corresponding two groups of extrusion sheets 11 to rotate in opposite directions to flatten the material.

[0031] The extrusion assembly includes four groups of fixed seats 7 fixedly connected to the support plate 5. The four groups of fixed seats 7 are symmetrically installed on both sides of the support plate 5. The four groups of fixed seats 7 are fixed to the support plate 5 by fixing bolts, and the corresponding two groups of fixed seats 7 are coaxially arranged. A rotating roller 8 is rotatably connected between the two opposite groups of fixed seats 7. A plurality of fixed blocks 9 are fixedly connected to the rotating roller 8, and a plurality of sliding blocks 10 arranged in a circular pattern are slidably connected to the rotating roller 8. The end of the sliding block 10 is fixedly connected to the extrusion sheet 11. The material is extruded by the action of the extrusion sheet 11 so that the material fits on the lower template 6. The sliding block 1 0 is fixedly connected with a first tension spring 12, and the first tension spring 12 is fixedly connected to the fixed block 9. The action of the first tension spring 12 can make the sliding block 10 drive the extrusion sheet 11 to reset, thereby making the extrusion sheet 11 able to move away from the material, thereby facilitating the material to be inserted between the extrusion sheet 11 and the lower template 6, and multiple groups of circumferentially arranged sliding blocks 10 are also arranged equidistantly along a straight line on the rotating roller 8. By setting up multiple groups of extrusion sheets 11, the contact area between the extrusion sheet 11 and the material can be increased, so that the extrusion sheet 11 can evenly extrude the material. One side of the sliding block 10 is equipped with a sliding connection with the rotating roller 8. The conical extrusion block 13 is provided, and the contact surface of the sliding block 10 and the conical extrusion block 13 is set to an oblique angle, so that the conical extrusion block 13 can extrude the sliding block 10, so that the sliding block 10 drives the extrusion piece 11 to move. A connecting column 14 is fixedly connected between the multiple groups of conical extrusion blocks 13. The sliding block 10 is extruded by the action of the conical block, so that the sliding block 10 drives the extrusion piece 11 to move. The end of the connecting column 14 extends into the interior of the machine body 1 and is connected to a sliding member for driving the connecting column 14 to slide. During the stamping process, the material is conveyed to the lower template 6 by the action of the conveyor, and then the material is conveyed to the lower template 6 by the starter. The machine body 1 will cause the telescopic rod 2 to drive the sliding plate 3 to move downward, thereby driving the upper template 4 to move downward, and punching the material through the action of the upper template 4 and the lower template 6. In this process, the connecting column 14 drives the conical extrusion block 13 to move through the action of the sliding part, and the sliding block 10 is extruded through the movement of the conical extrusion block 13. The sliding block 10 is moved by the extrusion action, and thus the extrusion sheet 11 is driven to move by the movement of the sliding block 10. In the process of the movement of the extrusion sheet 11, it will gradually approach the material until it is extruded, and then the material will be squeezed and fit on the end face of the lower template 6.

[0032] The sliding member includes a sliding rod 20 that is rotatably connected to the two groups of connecting columns 14 respectively. The sliding of the sliding rod 20 causes the connecting column 14 to move. One end of the sliding rod 20 is fixedly connected to a movable block 21. The outer side surface of the movable block 21 is provided with a sleeve 22 fixed to the inside of the body 1. By controlling the air pressure inside the sleeve 22, the forward and backward movement of the movable block 21 is controlled, so that the sliding rod 20 drives the connecting column 14 to move forward and backward. A second tension spring 23 fixedly connected to the movable block 21 is fixedly connected to the sleeve 22. The action of the second tension spring 23 facilitates the resetting of the movable block 21. The end of the sleeve 22 is connected to a connecting pipe 24. A pressure control component for controlling the internal pressure of the sleeve 22 is connected between the two groups of connecting pipes 24. The pressure control component facilitates the control of the pressure inside the sleeve 22.

[0033] The pressure control part includes a motor 25 fixed on the body 1. The motor 25 is a forward and reverse motor 25. The output end of the motor 25 is fixedly connected to a threaded rod 26. The outer side of the threaded rod 26 is threadedly connected to a threaded sleeve 27. The threaded rod 26 is driven forward and reverse by the motor 25, thereby enabling the threaded sleeve 27 to move forward and backward. A sliding piece 28 is fixedly connected to the threaded sleeve 27. The outer side of the sliding piece 28 is slidably connected to the pressure control tube 31, and a spring 29 is fixedly connected to the sliding piece 28. The end of the spring 29 is fixedly connected to a spring that slides with the pressure control tube 31. The piston block 30 is connected, and a spring 29 is installed between the sliding piece 28 and the piston block 30. Therefore, after the piston block 30 stops moving, the sliding piece 28 can continue to move and is used as a buffer. The threaded rod 26 is connected to the transmission member. During the extrusion process, the motor 25 is controlled to rotate forward, and then the rotation of the motor 25 causes the threaded rod 26 to drive the threaded sleeve 27 to move, and the movement of the threaded sleeve 27 causes the sliding piece 28 to move. The movement of the sliding piece 28 causes the spring 29 to squeeze the piston block 30. Since the piston block 30 There is no obstruction at the beginning of the movement, so the sliding piece 28 is squeezed by the spring 29 to move the piston block 30. Therefore, the movement of the piston block 30 squeezes the gas inside the pressure control tube 31 into the inside of the sleeve 22 through the connecting pipe 24, thereby increasing the air pressure inside the sleeve 22. The action of the air pressure causes the movable block 21 inside the sleeve 22 to move. Therefore, the movement of the movable block 21 will drive the sliding rod 20 to move, and the movement of the sliding rod 20 will drive the connecting column 14 to slide. After the extrusion is completed, the control motor 25 is reversed. The threaded rod 26 drives the threaded sleeve 27 to move in the opposite direction, and the movement of the sliding piece 28 causes the spring 29 to pull the piston block 30 to move in the opposite direction. Therefore, the gas inside the sleeve 22 is extracted by the reverse movement of the piston block 30, so that the air pressure inside the sleeve 22 is reduced, and the movable block 21 drives the sliding rod 20 to move in the opposite direction through the negative pressure, thereby pulling the connecting column 14 to move in the opposite direction and reset. After that, the conical extrusion block 13 also moves in the opposite direction and resets. At this time, the sliding block 10 drives the extrusion piece 11 to reset through the action of the first tension spring 12.

[0034] Example 2: Please refer to Figure 3 and Figure 8 , this embodiment further explains Example 1. The leveling assembly in the figure includes connecting blocks 15 fixedly connected to the two groups of rotating rollers 8 respectively. The connecting blocks 15 are sleeved on the outer side of the connecting column 14. The connecting blocks 15 are equivalent to couplings, serving as the connecting structure between the first connecting shaft 16 and the second connecting shaft 17 and the two groups of rotating rollers 8. The ends of the two groups of connecting blocks 15 are fixedly connected to the first connecting shaft 16 and the second connecting shaft 17 respectively. The first connecting shaft 16 and the second connecting shaft 17 are sleeved on the outer side surfaces of the two groups of connecting columns 14 respectively, and a first spur gear 18 is fixedly connected to the second connecting shaft 17. The outer side surface of the first spur gear 18 is meshed with the second spur gear 19. A transmission member connected to the sliding member is installed between the second spur gear 19 and the first connecting shaft 16. The transmission member rotates the second connecting shaft 17 and the second spur gear 19, and then the first spur gear 18 drives the first connecting shaft 16 to rotate.

[0035] The transmission member includes a transmission shaft 32 fixedly connected to the threaded rod 26, the threaded rod 26 causes the transmission shaft 32 to rotate, the transmission shaft 32 is rotatably connected to the pressure control tube 31 and the piston block 30, and the end of the transmission shaft 32 is fixedly connected to a driving wheel 33, the transmission shaft 32 causes the driving wheel 33 to rotate, and the outer side surface of the driving wheel 33 is transmission-connected with a belt 34, and the action of the belt 34 causes two groups of driven wheels 35 to rotate, and two groups of driven wheels 35 are transmission-connected on the belt 34, one group of driven wheels 35 is fixedly connected to the second connecting shaft 17, and the driven wheels cause the second connecting shaft 17 to rotate, and the axis of the other group of driven wheels is fixedly connected to a rotating column fixedly connected to the second flat gear 19, and the other group of driven wheels will cause the second flat gear 19 to rotate, and the rotating column is rotatably connected to the body 1, and the body 1 supports the rotating column, and the extrusion sheet 11 is connected to the object After the material is extruded, the control motor 25 continues to rotate forward. At this time, the threaded rod 26 will drive the transmission shaft 32 to rotate, and the driving wheel 33 will be driven to rotate through the action of the transmission shaft 32. The driving wheel 33 will drive two sets of driven wheels 35 to rotate through the belt 34, one set of driven wheels 35 will drive the second connecting shaft 17 to rotate, and the other set of driven wheels 35 will drive the second flat gear 19 to rotate through the rotating column, and the first connecting shaft 16 will be driven to rotate through the second flat gear 19. Due to the action of the first flat gear 18 and the second flat gear 19, the rotation directions of the first connecting shaft 16 and the second connecting shaft 17 are opposite. Therefore, the rotation of the first connecting shaft 16 and the second connecting shaft 17 causes the two sets of rotating rollers 8 to rotate, thereby causing the extrusion sheet 11 to rotate, and the rotation of the extrusion sheet 11 will flatten the material on the lower template 6, thereby improving the stamping accuracy.

[0036] Example 3: Please refer to Figure 1-Figure 3, this embodiment further explains other embodiments. The rotating roller 8 in the figure is installed in the middle position of the support plate 5. The rotating roller 8 is installed in the middle position of the support plate 5 so that the rotating roller 8 can be located in the middle position of the material to be punched, so it is convenient for the extrusion sheet 11 on the rotating roller 8 to extrude the material, and the outer side of the extrusion sheet 11 is provided with a detachable anti-slip sheet to increase the friction between the extrusion sheet 11 and the material, thereby facilitating the flattening of the material on the lower template 6. During the processing, the rotating roller 8 is located in the middle of the support plate 5, so that the rotating roller 8 is just in the middle position of the lower template 6. Therefore, the extrusion sheets 11 evenly arranged on the rotating roller 8 are evenly distributed above the lower template 6. Therefore, during the extrusion and flattening process, the extrusion sheet 11 can evenly extrude the material.

[0037] Working principle: During the extrusion process, the material is conveyed between the lower template 6 and the rotating roller 8 by the action of the conveyor, and then the motor 25 is controlled to rotate forward, and the rotation of the motor 25 causes the threaded rod 26 to drive the threaded sleeve 27 to move, and the movement of the threaded sleeve 27 causes the sliding piece 28 to move, and the movement of the sliding piece 28 causes the spring 29 to squeeze the piston block 30. Since the piston block 30 has no obstruction in the initial stage of movement, the sliding piece 28 is squeezed by the spring 29 to move the piston block 30. Therefore, the movement of the piston block 30 squeezes the gas inside the pressure control tube 31 into the inside of the sleeve 22 through the connecting pipe 24, thereby increasing the air pressure inside the sleeve 22, and the movable block 21 inside the sleeve 22 is moved by the action of the air pressure. The movement of the movable block 21 will drive the sliding rod 20 to move, and the movement of the sliding rod 20 will drive the connecting column 14 to slide, and the sliding of the connecting column 14 will move the conical extrusion block 13, and the sliding block 10 will be squeezed by the movement of the conical extrusion block 13. The sliding block 10 is moved by the extrusion effect, and the extrusion piece 11 is driven to move by the movement of the sliding block 10. In the process of the movement of the extrusion piece 11, it will gradually approach the material until the material is squeezed, and then the material is squeezed and fitted to the end surface of the lower template 6. In this process, the first tension spring 12 is in a stretched state. In this process, the movement of the sliding block 10 and the extrusion piece 11 is moved by the change of the air pressure inside the sleeve 22. After the material is squeezed and contacted, the air pressure inside the sleeve 22 will not change, so the piston block 30 inside the sleeve 22 will not continue to move. Afterwards, the motor 25 continues to rotate forward to make the threaded rod 26 rotate forward, and then the threaded sleeve 27 continues to move through the rotation of the threaded rod 26, and then the threaded sleeve 27 drives the sliding piece 28 to move to compress the spring 29, and the piston block 30 will not move. In this process, the rotation of the threaded rod 26 will make the transmission shaft 32 rotate, so the rotation of the transmission shaft 32 will drive the driving wheel 33 to rotate, and the driving wheel 33 will drive two sets of driven wheels 35 to rotate through the belt 34, one set of driven wheels 35 will drive the second connecting shaft 17 to rotate, and the other set of driven wheels 35 will drive the second flat gear 19 to rotate through the rotating column. The second spur gear 19 drives the first connecting shaft 16 to rotate. Due to the action of the first spur gear 18 and the second spur gear 19, the rotation directions of the first connecting shaft 16 and the second connecting shaft 17 are opposite. Therefore, the rotation of the first connecting shaft 16 and the second connecting shaft 17 causes the two sets of rotating rollers 8 to rotate, thereby causing the extrusion sheet 11 to rotate. The rotation of the extrusion sheet 11 flattens the material on the lower template 6, thereby improving the precision of the stamping. Afterwards, by starting the machine body 1, the machine body 1 will cause the telescopic rod 2 to drive the sliding plate 3 to move downward, thereby driving the upper template 4 to move downward, and the material is stamped by the action of the upper template 4 and the lower template 6. Through the extrusion and flattening actions, the material is tightly and stably attached to the end face of the lower template 6, thereby improving the precision of the stamping;

[0038] After the stamping is completed, the control motor 25 is reversed. The reversal of the motor 25 causes the threaded sleeve 27 to drive the sliding piece 28 to move in the opposite direction and reset. Therefore, the sliding piece 28 pulls the spring 29 to reset the piston block 30. When the piston block 30 moves in the opposite direction, the gas inside the sleeve 22 is extracted through the connecting pipe 24 to reduce the air pressure inside the sleeve 22. Therefore, the movable block 21 is moved in the opposite direction and reset by the action of the negative pressure. The sliding rod 20 is pulled to reset by the action of the movable block 21, so that the connecting column 14 and the conical extrusion block 13 are reset. At this time, since the sliding block 10 has lost the extrusion force, the sliding block 10 drives the extrusion piece 11 to reset through the action of the first tension spring 12. After that, the conveyor transports the material again, and then repeats the above action to stamp the material again.

[0039] It is worth noting that the extrusion sheet 11 in this solution is able to slide, thereby facilitating the extrusion of materials of different thicknesses, thereby improving the practicability of the device.
