Description

Technical Field

[0001] The present invention relates to the technical field of loading and unloading of hydraulic presses, and specifically to a hot press forming device for manufacturing rescue lifting air cushions using a high-temperature hydraulic press. Background Art

[0002] The rescue lifting air cushion consists of an air cushion, a connecting pipe, an inflation bottle, etc. When producing the rescue lifting air cushion, the air cushion body needs to be processed. Among them, a high-temperature hydraulic press is required for hot press forming. Plastic or rubber raw materials are placed in a mold, and the raw materials are pressed into shape through high temperature.

[0003] After the existing high-temperature hydraulic press hot press forms the rescue lifting air cushion mold once, the mold needs to be taken out. Then, a new air cushion mold filled with raw materials is placed on the floor of the high-temperature hydraulic press, and then the machine is started to re-perform high-temperature hot forming on the new air cushion mold. In this process, when the number of workers is fixed, two operations need to be carried out successively, that is, the blanking operation of the forming mold, and then the feeding operation of the new mold. This prolongs the preparation time for loading and unloading when manufacturing a large number of rescue lifting air cushions and delays the manufacturing efficiency.

[0004] Therefore, we propose a hot press forming device for manufacturing rescue lifting air cushions using a high-temperature hydraulic press to solve the problems encountered above. Summary of the Invention

[0036] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0037] Please refer to Figures 1-8 As shown, the hot oil press molding device for manufacturing a rescue lifting air cushion includes a main body 1 of the oil press. A bottom plate 2 is provided at the bottom of the main body 1 of the oil press. Lapping plates 3 are fixedly provided on both sides of the bottom plate 2 symmetrically. Erection plates 4 are fixedly provided on the same side of the two lapping plates 3. The erection plate 4 is fixedly connected to one side of the bottom plate 2. A diagonal bracing structure is also provided between the lapping plate 3 and the bottom plate 2 to improve the stability of the lapping plate 3 after fixation. Reinforcing pads can also be provided on the side of the lapping plate 3 away from the floor 2 and fixedly connected to the ground, which also has the effect of improving the support stability of the lapping plate 3. The erection plate 4 is used to facilitate the fixation of the electric slide table 5.

[0038] An electric slide table 5 is fixedly provided on the top of the erection plate 4. Both ends of the electric slide table 5 are abutted against the two lapping plates 3 respectively. A moving frame 501 is slidably connected to the electric slide table 5 along the length direction. The electric slide table 5 is used to drive the support plate 19 to move in a straight line in one direction through the moving frame 501, providing the possibility for the automation of the loading and unloading of the air cushion mold 32.

[0039] A main slide frame 6 is fixedly provided at the center of the top of the bottom plate 2. Side slide frames 7 are lapped at both ends of the main slide frame 6. The side slide frames 7 are fixedly provided on the top of the adjacent lapping plates 3. Chutes 8 are respectively provided on both sides of the top of the main slide frame 6 and the side slide frames 7 symmetrically. A resisting groove 16 is also provided on one side of the top of the main slide frame 6. The main slide frame 6 and the side slide frames 7 are used to cooperate with the guide wheels 31 and the feeding plate 30 to send the air cushion mold 32 into and out of the inside and outside of the main body 1 of the oil press. The chute 8 is used to guide the movement of the guide wheels 31 and limit the guide wheels 31 at the same time, so that the guide wheels 31 can only slide within the limit. The resisting groove 16 is used to enable the resisting member 38 to slide therein, facilitating its upward extension under the main slide frame 6.

[0040] A cavity 601 is formed at the bottom of the main carriage 6. Limiting grooves 602 are respectively formed at the four corners of the top of the main carriage 6. The top end of the limiting groove 602 communicates with the sliding groove 8, and the bottom end of the limiting groove 602 communicates with the cavity 601. A limiting block 9 is slidably connected in the limiting groove 602. The bottoms of the four limiting blocks 9 are connected to the same lifting plate 10. The cavity 601 can be used to accommodate and install the limiting lifting assembly 14 and the resisting lifting assembly 15. The limiting groove 602 is used to guide the lifting of the limiting block 9. When the limiting block 9 reaches the highest lifting position along with the lifting plate 10, the top surface of the limiting block 9 is parallel to the bottom surface of the sliding groove 8. At this time, the guide wheel 31 is allowed to pass through. When the limiting block 9 descends, it will cause the upper guide wheel 31 to synchronously descend under the action of gravity along with the limiting block 9 until both moving paths of the guide wheel 31 along the length direction of the sliding groove 8 are blocked by the limiting groove 602 until the bottom of the feeding plate 30 abuts against the top of the main carriage 6. The lifting plate 10 is provided to facilitate the synchronous driving of multiple limiting blocks 9 to perform synchronous lifting movements;

[0041] A first connecting plate 11 is fixedly provided at the center of the cavity 601. A second connecting plate 12 and a third connecting plate 13 are respectively arranged on both sides of the first connecting plate 11. The two ends of the second connecting plate 12 and the third connecting plate 13 are respectively fixedly connected to the adjacent inner walls of the main carriage 6;

[0042] A limiting lifting assembly 14 and a resisting lifting assembly 15 are respectively arranged in the cavity 601;

[0043] A guide plate 17 is also fixedly provided on the top of the main carriage 6. The two ends of the guide plate 17 respectively extend to the top of the overlapping plate 3 on one side. A pushing assembly 18 is arranged on the guide plate 17.

[0044] In this embodiment, the pushing assembly 18 includes a pushing rack 1801 slidably connected to the top of the guide plate 17. A plurality of fixed teeth 1802 are arranged on one side of the guide plate 17 close to the overlapping plate 3 on one side and are equally spaced along the length direction of the guide plate 17. A support plate 19 is fixedly provided on the moving frame 501. A rotating shaft 20 is rotatably provided on the support plate 19. A gear 21 is fixedly connected to the bottom end of the rotating shaft 20. The gear 21 meshes with the fixed teeth 1802 and the pushing rack 1801 respectively. Two groups of rod assemblies 22 are arranged before and after the top of the pushing rack 1801.

[0045] It should be noted that the pushing rack 1801 is guided by the guide plate 17. It is driven by the gear 21 through meshing with the gear 21. The gear 21 meshes with the fixed tooth profile 1802 and the pushing rack 1801 at the same time. This enables the gear 21 to move and rotate synchronously when it moves with the moving frame 501. Since the gear 21 drives the pushing rack 1801 to move synchronously and the same distance when it is stationary and meshed with the pushing rack 1801, and the gear 21 rotates when it moves, it will further drive the pushing rack 1801 to move a certain distance further on the basis of the original translation distance through meshing with the pushing rack 1801, so as to realize the long-distance movement of the pushing rack 1801 by the gear 21 in a short distance. Furthermore, the width requirements of the two side overlapping plates 3 and the erection plate 4 can be reduced, the material use can be reduced, and the floor area can be reduced at the same time. The rod assembly 22 is used to push the feeding plate 30 with the air cushion mold 32 to move in one direction. Through the above structure, the two rod assemblies 22 can drive the two feeding plates 30 to move in one direction along the sliding frame at the same time. With the cooperation of the electric sliding table 5, the moving frame 501, the main sliding frame 6, the side sliding frame 7, the feeding plate 30 and the pushing assembly 18, the synchronous feeding and discharging operations of the air cushion mold 32 can be realized after the high-temperature thermoforming of the rescue lifting air cushion. Moreover, the driving structures of the feeding and discharging operations are the same, which ensures the synchronization of the operations, reduces the requirements for the control system, simplifies the intermediate steps at the same time, reduces the downtime, and improves the manufacturing efficiency when manufacturing a large number of rescue lifting air cushions.

[0046] In this embodiment, the rod assembly 22 includes a bent rod 23 fixed to the top of the pushing rack 1801. One end of the bent rod 23 is fixed with a support rod 24. The top of the support rod 24 is fixed with a fixed shaft 25. A pushing rod 26 is rotatably connected to the outside of the fixed shaft 25. A torsion spring 27 is sleeved on the upper side of the fixed shaft 25. The two ends of the torsion spring 27 are respectively fixed to the pushing rod 26 and a side wall of the fixed shaft 25.

[0047] It should be noted that the bent rod 23 is set in an L shape. During the movement process, when the bent rod 23 approaches the moving frame 501 with the gear 21, mutual avoidance is achieved through position change to avoid collision. The support rod 24 is used to lift the height of the push rod 26, and the torsion spring 27 is used to ensure that the push rod 26 always has a tendency to rotate and move in the direction close to one side of the limit adjustment block 28. This design enables the front rod assembly 22 to drive the air cushion press mold 32 for press forming to unload materials. At this time, a newly loaded air cushion press mold 32 already exists on the main carriage 6. Then, it is necessary to drive the front rod assembly 22 to reset. During the reset process of the front rod assembly 22, it needs to cross the newly loaded air cushion press mold 32. When the push rod 26 in the front rod assembly 22 contacts the new air cushion press mold 32, it will rotate around the fixed shaft 25 under the resistance force until it completely crosses the newly loaded air cushion press mold 32 with the rod assembly 22 and the push rack 1801. After that, the push rod 26 in the front rod assembly 22 no longer contacts the newly loaded air cushion press mold 32. At this time, the previously deflected push rod 26 will reset under the elastic force of the torsion spring 27 until one side of it abuts against one side of the limit adjustment block 28. Then, by controlling the reverse movement of the moving frame 501, the push rod 26 in the reset front rod assembly 22 is driven to approach the newly loaded air cushion press mold 32 again until it abuts against it. By setting the rod assembly 22, it can not only realize the function of pushing the feeding plate 30 and the air cushion press mold 32 on it to move for loading and unloading materials, but also automatically bypass the newly loaded air cushion press mold 32 during reset to avoid interference.

[0048] In this embodiment, a limit adjustment block 28 is also fixedly arranged on one side of the top of the support rod 24. An arc-shaped card slot 29 is formed on one side of the limit adjustment block 28 close to the push rod 26. The limit adjustment block 28 is used to limit the one-way maximum rotation angle of the push rod 26. The arc-shaped card slot 29 on it adapts to the outer contour of the part of the push rod 26 close to the fixed shaft 25. Through the combined action of the limit adjustment block 28 and the torsion spring 27, the limiting and reset functions of the push rod 26 can be realized.

[0049] In this embodiment, feeding plates 30 are arranged on the tops of the main carriage 6 and one side carriage 7. Rotatable guide wheels 31 are arranged at the four corners of the bottom of the feeding plate 30. The guide wheels 31 are movably connected in the adjacent sliding grooves 8. The air cushion press mold 32 is detachably connected to the top of the feeding plate 30. By arranging the guide wheels 31, the friction force when the feeding plate 30 drives the air cushion press mold 32 to move can be reduced, thereby improving the loading and unloading speed. Secondly, the wear caused by the long-term friction between the feeding plate 30 and the carriage can be reduced.

[0050] In this embodiment, the limit lifting assembly 14 includes a motor 40 fixedly arranged at the bottom of the second connecting plate 12. A sprocket 33 is respectively arranged at the center of the top of the cavity 601 and on one side close to the motor 40. A chain belt 34 is tensioned on the outer sides of the two sprockets 33. The output end of the motor 40 is fixedly connected to the adjacent sprocket 33 through a connecting shaft. A threaded rod 35 is rotatably connected between the adjacent inner walls of the first connecting plate 11 and the cavity 601. The adjacent sprockets 33 are fixedly arranged on the outer side of the threaded rod 35. The lifting plate 10 is threadedly arranged on the outer side of the threaded rod 35 through a connecting member.

[0051] It should be noted that the second connecting plate 12 is used to fix the motor 40, and the threaded rod 35 is driven to rotate through the sprockets 33 and the chain belt 34. Since it is necessary to ensure the flatness of the bottom plane of the main carriage 6, the motor 40 cannot be directly arranged under the threaded rod 35. Therefore, the structure of the sprockets 33 and the chain belt 34 is adopted to adjust the installation position of the motor 40 to ensure that the bottom of the motor 40 does not protrude from the bottom plane of the main carriage 6. When the threaded rod 35 rotates, through the threaded fit between it and the structure inside the lifting plate 10, and at the same time, the rotation of the limiting block 9 on the lifting plate 10 is restricted by the limiting groove 602, the lifting plate 10 can only move up and down outside the threaded rod 35. Through the arranged limit lifting assembly, the four guide wheels 31 under the feeding plate 30 with the air cushion die 32 reaching the fixed position on the main carriage 6 can be lowered along with the limiting block 9 until the bottom of the feeding plate 30 abuts against the top plane of the main carriage 6. This structure can avoid the damage of the guide wheels 31 caused by force during the high-temperature thermoforming process, thereby ensuring the normal service life of the guide wheels 31 and optimizing the structural design.

[0052] In this embodiment, a through hole is opened at the center of the top of the lifting plate 10, and a threaded sleeve is fixedly arranged in the through hole. The threaded sleeve is threadedly connected to the threaded rod 35. By adopting the threaded sleeve installed in the through hole, it is convenient for the threaded fit between the lifting plate 10 and the threaded rod 35, and at the same time, it is convenient for the processing and installation of the threaded sleeve and the lifting plate 10.

[0053] In this embodiment, the resisting and lifting assembly 15 includes an electromagnet 36 fixedly arranged on the third connecting plate 13. A bracket 37 is also arranged on one side of the cavity 601 close to the third connecting plate 13. One side of the bracket 37 is fixedly connected to the adjacent inner wall of the main carriage 6. A resisting member 38 is also arranged inside the bracket 37. The resisting member 38 includes a resisting block 3801 slidably connected in the resisting groove 16. A magnet end 3802 is fixedly arranged at the bottom of the resisting block 3801. After the electromagnet 36 is energized, the end close to the magnet end 3802 and the adjacent end on the magnet end 3802 belong to the same-sex magnetic poles.

[0054] It should be noted that the bracket 37 is used to separate the electromagnet 36 and the resisting member 38. The bracket 37 is of a U-shaped structure, and a through groove is centrally formed at a position between the electromagnet 36 and the resisting member 38 thereon to reduce the shielding effect. At the same time, the bracket 37 is made of a non-magnetic material, such as aluminum alloy or engineering plastic. The outer cross-section of the resisting block 3801 is adapted to the cross-sectional contour of the resisting groove 16, and it can move up and down in the resisting groove 16. The cross-section of the magnet end 3802 is larger than the cross-section of the resisting groove 16 and is used to limit the maximum rising height of the resisting block 3801. After the electromagnet 36 is energized, since one end of the electromagnet 36 close to the magnet end 3802 and the magnet end 3802 are of the same-sex magnetic poles, they will be subjected to a mutual repulsive force. The electromagnet 36 is fixed and cannot move. Therefore, the magnet end 3802 will drive the resisting block 3801 to rise under the action of the repulsive force until the upper surface of the magnet end 3802 abuts against the bottom of the main carriage 6. At this time, the upper part of the rising resisting block 3801 is exposed outside the resisting groove 16 to form an obstacle, blocking the front edge of the feeding plate 30 during movement, so that the feeding plate 30 stops near the current position. At the same time, under the contact and limiting action of the pushing rod 26 closely following behind, the feeding plate 30 stops at a set position on the main carriage 6. This set position is located between the four limiting corner blocks 39. By providing the resisting lifting assembly 15, the feeding plate 30 can be forced to stop at a designated position, while meeting the narrow installation position at the bottom of the main carriage 6. At the same time, through its cooperation with the rod assembly 22, precise positioning of the feeding plate 30 and the air cushion die 32 to be processed can be achieved. At the same time, in cooperation with the limiting lifting assembly 14, the guide wheels 31 under the feeding plate 30 can accurately lift and lower along with the limiting block 9, ensuring the stability during the manufacture of the air cushion die.

[0055] In this embodiment, limiting corner blocks 39 are also fixedly provided at the four corners of the center of the top of the main carriage 6. The limiting corner blocks 39 are used to further limit the feeding plate 30 after the guide wheels 31 on the main carriage 6 lower their heights along with the limiting block 9, making it difficult to move in four directions, and further improving the stability during the hot pressing forming of the seven-point die at high temperature.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made.
