DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0042] Example:

[0043] See also Figure 1-Figure 5 The present invention provides a technical solution: a stamping die for a body cover of an engineering vehicle control room, comprising a working frame 1, a lower module 2 is fixedly installed above the bottom end of the working frame 1, an upper module 3 is arranged below the top end of the working frame 1, a stamping cavity 23 is opened on the top surface of the lower module 2, a stamping part 8 is arranged above the stamping cavity 23, the upper module 3 is located directly above the lower module 2, and the stamping part 8 is located between the upper module 3 and the lower module 2, a fixed guide column 4 is fixedly installed below the top end of the working frame 1, and the four corners of the upper module 3 pass through the fixed guide column 4, a pressing slide frame 6 is arranged on the side of the working frame 1 facing the upper module 3 and the lower module 2, a fixing member 10 is arranged on the side of the pressing slide frame 6 facing the lower module 2, the fixing member 10 contacts the side of the stamping part 8 and fixes the stamping part 8, a lifting mechanism is arranged inside the lower module 2, and the lifting mechanism is located below the stamping part 8, an exhaust channel 25 is arranged in the stamping cavity 23, and an exhaust mechanism is arranged inside the exhaust channel 25.

[0044] In this embodiment, a sliding cavity 9 is opened on the side of the working frame 1 facing the lower module 2 and the upper module 3, and a first fixed column 13 is fixedly installed in the sliding cavity 9. A first compression spring 11 is movably installed on the outer side of the first fixed column 13. The first fixed column 13 passes through the downward pressing slide frame 6, and two adjacent sections of the first compression spring 11 are respectively located on the upper and lower sides of the downward pressing slide frame 6 and are fixedly connected to the downward pressing slide frame 6.

[0045] The sliding cavity 9 provides space for the downward pressing slide frame 6 to move before and after work, and the first compression spring 11 provides elastic force and pressure when the downward pressing slide frame 6 works. The spring length of the first compression spring 11 above the downward pressing slide frame 6 is less than the spring length of the first compression spring 11 below the downward pressing slide frame 6, so that when the downward pressing slide frame 6 is pressed down by the upper module 3, the downward pressing slide frame 6 can fix the end of the stamping part 8 through the fixing part 10, thereby increasing the stamping part 8 to maintain a stable state during the stamping process and not deviate to one side, so that the stamping part 8 can better complete the stamping work.

[0046] In this embodiment, a second fixed column 14 is fixedly installed inside the downward sliding frame 6, and a first sliding block 15 and a second compression spring 16 are movably installed on the outer side of the second fixed column 14. A pushing column 17 is installed on one side of the first sliding block 15, and the other end of the pushing column 17 passes through the downward sliding frame 6 and is fixedly connected to the fixing member 10.

[0047] Both sides of the first sliding block 15 are fixedly connected to the second compression spring 16. The length of the second compression spring 16 on the side facing the push column 17 is less than the length of the second compression spring 16 on the side away from the push column 17. When the fixing member 10 fixes the stamping member 8, the second compression spring 16 on the left side of the first sliding block 15 will be stretched, and the second compression spring 16 on the right side of the first sliding block 15 will be squeezed. After the fixing member 10 is separated from the stamping member 8, that is, when the squeezing force on the first sliding block 15 disappears, the second compression spring 16 on the left side is stretched. The elastic force will be released, thereby driving the first sliding block 15 to move away from the pushing column 17, and the contraction elastic force of the second compression spring 16 on the right side will be released, which will also push the first sliding block 15 to move away from the pushing column 17, so that the distance that the pushing column 17 retracts to the lower pressing slide frame 6 becomes longer, thereby separating the fixing part 10 from the stamping part 8. That is, after the upper module 3 moves upward, the fixing part 10 is separated from the edge of the stamping part 8 by the elastic force of the second compression spring 16, which is convenient for the subsequent demolding of the stamping part 8.

[0048] In this embodiment, extrusion blocks 12 are fixedly installed on both sides of the bottom end of the upper module 3, and an extrusion oblique block 19 is fixedly installed on the bottom end of the extrusion block 12. A connecting oblique block 18 is fixedly installed on the top end of the first sliding block 15. The bottom end of the extrusion oblique block 19 is in active contact with the top end of the connecting oblique block 18. The contact sides of the extrusion oblique block 19 and the connecting oblique block 18 are provided with mutually matching bevel edges, and the extrusion oblique block 19 moves downward and contacts the connecting oblique block 18, driving the first sliding block 15 to move to one side of the push column 17, and the lower An inclined edge is provided on the top side of the pressing and sliding frame 6, and a first sliding through hole 20 matching the extrusion bevel block 19 and the connecting bevel block 18 is provided through the inclined edge. During the downward movement of the extrusion bevel block 19, the connecting bevel block 18 will move toward the side of the pushing column 17 through the inclined edge, and as the downward movement distance of the extrusion block 12 changes, the extrusion bevel block 19 will drive the connecting bevel block 18 to move an increased distance, thereby moving the fixing part 10 toward the side of the stamping part 8, and fixing the stamping part 8 through the fixing part 10.

[0049] When the stamping part 8 is stamped, the downward movement of the upper module 3 will drive the extrusion block 12 to move downward together. When the extrusion block 12 moves downward, it will contact with the connecting oblique block 18 through the extrusion oblique block 19. When the connecting oblique block 18 is subjected to the extrusion force of the extrusion oblique block 19, the connecting oblique block 18 will drive the first sliding block 15 to move toward the side of the pushing column 17 through the contact of the oblique edges between the two. When the first sliding block 15 moves, the second compression spring 16 on its left side will be stretched, and the second compression spring 16 on its right side will be squeezed. At the same time, when the first sliding block 15 moves, it will drive the fixing member 10 to move through the pushing column 17. One side of the fixing part 8 moves, and when the pressing slide frame 6 is pressed downward by the upper module 3, the other end of the pressing slide frame 6 slides on the first fixing column 13 and moves downward, and squeezes the first compression spring 11 below the pressing slide frame 6, so that the pressing slide frame 6 can move downward, so that the fixing part 10 and the stamping part 8 are in contact with each other. After the stamping work of the upper module 3 is completed, the upper module 3 will return to its original position, so that the downward extrusion force received by the pressing slide frame 6 disappears, and when the elastic force of the first compression spring 11 below the pressing slide frame 6 is released, the pressing slide frame 6 will return to its original position and wait for the next work.

[0050] The inclined edge of the extrusion bevel block 19 faces the side close to the fixed part 10, and the inclined edge of the connecting bevel block 18 faces the side away from the fixed part 10. During the downward movement of the extrusion bevel block 19, the extrusion bevel block 19 will move the connecting bevel block 18 toward the side of the fixed part 10 through the inclined edge, and will cause the second compression spring 16 of the first sliding block 15 away from the side of the fixed part 10 to be stretched, and the second compression spring 16 on the other side of the first sliding block 15 is squeezed. After the stamping is completed, the extrusion block 12 and the extrusion bevel block 19 will move upward with the upper module 3, and the extrusion block 12 will be separated from the top of the fixed part 10, the extrusion force on the connecting bevel block 18 will disappear, and under the action of the two sections of the second compression springs 16, the first sliding block 15 will drive the fixed part 10 and the stamping part 8 to separate from each other, thereby completing the fixation of the stamping part 8.

[0051] A fixing groove matching the stamping part 8 is provided on the side of the fixing part 10 facing the stamping part 8 , so that the fixing part 10 can fix the stamping part 8 and prevent the stamping part 10 from shifting.

[0052] During the downward movement of the extrusion block 12, when the fixing part 10 and the stamping part 8 contact each other, the bottom end of the extrusion block 12 contacts the top end of the fixing part 10, so that the extrusion block 12 fixes the top end of the fixing part 10. When the fixing part 10 fixes the stamping part 8, the contact between the extrusion block 12 and the top end of the fixing part 10 further fixes the fixing part 10, thereby further increasing the fixing effect of the fixing part 10 on the stamping part 8.

[0053] See also Figure 6-Figure 9 The present invention provides another technical solution, a lifting mechanism is arranged inside the lower module 2, the lifting mechanism is located below the stamping part 8, the lifting mechanism includes a lifting rack column 24, the top end of the lifting rack column 24 contacts the bottom end of the stamping part 8, and a third fixing column 26 is arranged through the side of the lifting rack column 24, and the third fixing column 26 is fixedly connected to the inner cavity wall of the lower module 2.

[0054] In this embodiment, a first rotating column 5 is movably installed on the outer side of the lower module 2, and a first rotating gear 21 and a second transmission wheel 33 are fixedly installed on the outer side of the first rotating column 5, a fixed rack column 7 is fixedly installed on the bottom side of the upper module 3, and a fourth fixed column 31 is fixedly installed on the upper bottom end of the working frame 1. The fixed rack column 7 is located on the outer side of the fourth fixed column 31 to ensure the stability of the fixed rack column 7 during the up and down movement and prevent the fixed rack column 7 from tilting to one side during the movement. The fixed rack column 7 is meshed and connected with the first rotating gear 21.

[0055] In this embodiment, the second rotating column 28 and the fourth rotating column 35 are movably installed in the inner cavity of the lower module 2, and the second rotating gear 27, the first transmission wheel 29 and the active bevel gear 30 are installed on the outer side of the second rotating column 28. The second rotating gear 27 is meshed and connected with the jacking rack column 24, and the first transmission belt 22 is movably installed on the outer sides of the first transmission wheel 29 and the second transmission wheel 33.

[0056] In this embodiment, a first driven bevel gear is fixedly mounted on the outer side of the fourth rotating column 35 , and the first driven bevel gear is meshingly connected with the driving bevel gear 30 .

[0057] After the upper module 3 completes the stamping work, the upper module 3 will move upward, and at the same time, it will also drive the fixed rack column 7 to move upward. When the fixed rack column 7 moves upward, it will drive the first rotating column 5 to rotate through the first rotating gear 21. In this way, when the first rotating column 5 rotates, it will drive the second rotating column 28 to rotate through the second transmission wheel 33, the first transmission belt 22 and the first transmission wheel 29. When the second rotating column 28 rotates, it will drive the second rotating gear 27 to rotate. When the second rotating gear 27 rotates, it will drive the lifting rack column 24 to move upward. When the lifting rack column 24 moves upward, the stamping part 8 will be demoulded out of the stamping cavity 23, which is convenient for the next step of the stamping part 8.

[0058] The lifting rack column 24 will be restricted by the third fixing column 26 when it moves, and the third fixing column 26 can ensure the stability of the lifting rack column 24 when it moves, so that the lifting rack column 24 always moves on the same straight line.

[0059] A vent hole is provided in the inner wall of the lower module 2 to facilitate the outflow of gas in the stamping cavity 23 .

[0060] See also Figure 10-15 The present invention provides another technical solution. The exhaust mechanism includes a fixed rod 40, an anti-blocking plate 41 and an air leakage hole 34. The anti-blocking plate 41 is fixedly installed below the fixed rod 40. The anti-blocking plate 41 is in contact with the inner wall of the exhaust channel 25 on all sides. The anti-blocking plate 41 is U-shaped, and both sides of the anti-blocking plate 41 are made of elastic plates, while the lifting block 43 is made of fixed rigid plates.

[0061] The protruding parts on both sides of the anti-blocking plate 41 are made of elastic plates. The elasticity of the elastic plates allows the anti-blocking plate 41 to contact the inner wall of the exhaust channel 25 on both sides when it is not pushed by the movable column 44 and the pushing block 45, and to block the air leakage hole 34 to prevent gas leakage in the stamping cavity 23. On the contrary, when the protruding parts on both sides of the anti-blocking plate 41 are pushed by the movable column 44 and the pushing block 45, the two sides of the anti-blocking plate 41 will be tilted and separated from the inner wall of the exhaust channel 25, so that the gas in the stamping cavity 23 can flow downward through the exhaust channel 25 and the air leakage hole 34, so that when the stamping part 8 is demolded, the gas in the stamping cavity 23 of the stamping part 8 will leak out, preventing the stamping part 8 from sticking to the inner wall of the stamping cavity 23, thereby increasing the demolding efficiency between the stamping part 8 and the stamping cavity 23.

[0062] In this embodiment, a fifth rotating column 38 is movably installed through the inner wall of the bottom end of the exhaust channel 25, a third driven bevel gear is fixedly installed on the outer side of the fifth rotating column 38, the second driven bevel gear is meshingly connected with the third driven bevel gear, and a threaded column 42 is fixedly installed on the top of the fifth rotating column 38.

[0063] In this embodiment, a fixed block 39 is fixedly installed inside the exhaust channel 25, and the bottom end of the fixed block 39 is threadedly connected to the outer side of the threaded column 42, and the outer side of the threaded column 42 is threadedly connected to a lifting block 43. Movable grooves 36 are provided inside both ends of the fixed block 39, and a connecting shaft 37 is movably installed on the inner wall of the movable groove 36. A rotating block 32 is fixedly installed between two adjacent connecting shafts 37, and a movable column 44 is movably installed inside the rotating block 32, and a pushing block 45 is fixedly installed at both ends of the movable column 44.

[0064] In this embodiment, the outer side of the pushing block 45 is provided with anti-slip grooves, and the upper and lower pushing blocks 45 are in friction contact with the outer side of the lifting block 43 and the outer side of the anti-blocking plate 41 respectively. The outer wall of the lifting block 43 is provided with a placement groove matching the pushing block 45, and the placement groove facilitates the contact between the pushing block 45 on the outer side of the lifting block 43 and the lifting block 43. The bottom sides of the protective plate 46 and the adjacent sides of the abutment block 49 are provided with beveled edges. When the protrusions on both sides of the anti-blocking plate 41 are squeezed, the abutment block 49 at the top of the anti-blocking plate 41 will move toward the middle of the anti-blocking plate 41, thereby leaking the air leakage hole 34, and the abutment block 49 will make the protective plate 46 move upward through the beveled edge, providing demolding for the stamping part 8. The convenience of one step, at the same time, the sliding support rod 48 will also move upward with the protective plate 46 and squeeze the third compression spring 47. Before the stamping device performs the next stamping work, the anti-blocking plate 41 will lose the squeezing force of the movable column 44 and the pushing block 45, and the two sides of the anti-blocking plate 41 will be in contact with the inner wall of the exhaust channel 23 through the elastic force of the anti-blocking plate 41 itself, and at the same time, the abutment block 49 will be driven to separate from the protective plate 46, so that the protective plate 46 returns to the original position at the top of the exhaust channel 23 under the release of the elastic force of the third compression spring 47, so that the inner wall of the entire stamping cavity 23 will remain flat, avoiding grooves in the stamping cavity 23, and preventing defects in the bottom stamping of the stamping part 8.

[0065] The lifting block 43 and the anti-blocking plate 41 are both U-shaped. The lifting block 43 is located below the anti-blocking plate 41, but the opening directions of the lifting block 43 and the anti-blocking plate 41 are opposite, that is, the opening of the lifting block 43 is downward, while the opening direction of the anti-blocking plate 41 is upward.

[0066] When the second rotating column 28 rotates, the fifth rotating column 38 will be driven to rotate through the active bevel gear 30, the first driven bevel gear, the fourth rotating column 35 and the third driven bevel gear. The rotation of the fifth rotating column 38 can drive the threaded column 42 to rotate. When the threaded column 42 rotates, it will drive the lifting block 43 to move upward. When the lifting block 43 moves upward, it will squeeze the protrusions on both sides of the anti-blocking plate 41 toward the middle of the anti-blocking plate 41 through the two pushing blocks 45 and the movable column 44, so that the protrusions on both sides of the anti-blocking plate 41 are separated from the inner wall of the exhaust channel 25. In this way, the squeezed air in the stamping cavity 23 at the bottom end of the stamping part 8 will flow out through the venting hole 34 in the exhaust channel 25, so that when the stamping part 8 is demolded, the air pressure on the upper and lower sides of the stamping part 8 is the same, which prevents the stamping part 8 from sticking to the inner wall of the stamping cavity 23 when the stamping part 8 is demolded, and prevents the stamping part 8 from being damaged during demolding.

[0067] During the rising process of the lifting block 43, the movable column 44 is movably installed in the rotating block 32. The two sides of the rotating block 32 are in the movable grooves 36 in the fixed block 39 through the connecting shafts 37. The rotating block 32 can be rotated in the movable grooves 36 through the connecting shafts 37, and the angle can be adjusted, while the movable column 44 can slide freely in the rotating column 32. The pushing blocks 5 at both ends of the movable column 44 are in contact with the outer side of the upper surface of the lifting block 43 and the outer side of the lower surface of the anti-blocking plate 41 respectively. In this way, during the upward movement of the lifting block 43, the pushing block 45 located above the lifting block 43 will squeeze the protrusions on both sides of the anti-blocking plate 41 toward the middle through the movable column 44 and the pushing block 45 on the other side of the movable column 44, so as to facilitate the unobstructed flow of the air leakage hole 34 in the exhaust channel 25.

[0068] In this embodiment, a third compression spring 47 and a sliding support rod 48 are movably installed inside the fixed rod 40. The third compression spring 47 is located above the bottom end of the sliding support rod 48, and the bottom end of the third compression spring 47 is fixedly connected to the sliding support rod 48. The top end of the third compression spring 47 is fixedly connected to the inner cavity wall of the fixed rod 40. A protective plate 46 is fixedly installed on the top end of the sliding support rod 48. Abutment blocks 49 are fixedly installed on the top ends of both sides of the anti-blocking plate 41. Both sides of the bottom end of the protective plate 46 are in sliding contact with the abutment blocks 49.

[0069] The working principle of this embodiment is as follows: during the downward movement, the extrusion bevel block 19 will cause the connecting bevel block 18 to move toward the push column 17 through the bevel edge, and as the downward movement distance of the extrusion block 12 changes, the extrusion bevel block 19 will drive the connecting bevel block 18 to move an increased distance, thereby causing the fixing part 10 to move toward the stamping part 8 and fix the stamping part 8 through the fixing part 10.

[0070] The upper module 3 will move upward, and at the same time will drive the fixed rack column 7 to move upward. When the fixed rack column 7 moves upward, it will drive the first rotating column 5 to rotate through the first rotating gear 21. In this way, when the first rotating column 5 rotates, it will drive the second rotating column 28 to rotate through the second transmission wheel 33, the first transmission belt 22 and the first transmission wheel 29. When the second rotating column 28 rotates, it will drive the second rotating gear 27 to rotate. When the second rotating gear 27 rotates, it will drive the lifting rack column 24 to move upward. When the lifting rack column 24 moves upward, the stamping part 8 will be demoulded out of the stamping cavity 23, which is convenient for the next step of the stamping part 8.

[0071] When the threaded column 42 rotates, it will drive the lifting block 43 to move upward. When the lifting block 43 moves upward, it will squeeze the protrusions on both sides of the anti-blocking plate 41 toward the middle of the anti-blocking plate 41 through the two pushing blocks 45 and the movable column 44, so that the protrusions on both sides of the anti-blocking plate 41 are separated from the inner wall of the exhaust channel 25. In this way, the squeezed air in the stamping cavity 23 at the bottom end of the stamping part 8 will flow out through the vent holes 34 in the exhaust channel 25, so that when the stamping part 8 is demolded, the air pressure on the upper and lower sides of the stamping part 8 is the same, which prevents the stamping part 8 from sticking to the inner wall of the stamping cavity 23 when the stamping part 8 is demolded, and prevents the stamping part 8 from being damaged during demolding.

[0072] During the rising process of the lifting block 43, the movable column 44 is movably installed in the rotating block 32. The two sides of the rotating block 32 are in the movable grooves 36 in the fixed block 39 through the connecting shafts 37. The rotating block 32 can be rotated in the movable grooves 36 through the connecting shafts 37, and the angle can be adjusted, while the movable column 44 can slide freely in the rotating column 32. The pushing blocks 5 at both ends of the movable column 44 are in contact with the outer side of the upper surface of the lifting block 43 and the outer side of the lower surface of the anti-blocking plate 41 respectively. In this way, during the upward movement of the lifting block 43, the pushing block 45 located above the lifting block 43 will squeeze the protrusions on both sides of the anti-blocking plate 41 toward the middle through the movable column 44 and the pushing block 45 on the other side of the movable column 44, so as to facilitate the unobstructed flow of the air leakage hole 34 in the exhaust channel 25.

[0073] After the hot gas leakage in the stamping cavity 23 is completed, when the upper module 3 performs the next stamping work, the threaded column 42 will be reversed when the upper module 3 is pressed down, and the lifting block 43 will move downward. When the lifting block 43 moves downward, the movable column 44 and the pushing block 45 will lose the upward squeezing force, so that the movable column 44 and the pushing block 45 will lose the squeezing of the anti-blocking plate 41, and the anti-blocking plate 41 will contact the inner wall of the exhaust channel 25 again under the action of its own elasticity, so as to close the exhaust channel 25.

Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
