This automatic stretching line for stainless steel processing features diverse functions, ease of use, and wide applicability.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic stretching line for stainless steel processing, comprising a hydraulic press and a mold body. A top plate is fixedly connected to the top of the hydraulic press, and several limiting rods are fixedly connected to the bottom of the top plate. A lifting rod is located at the bottom of the top plate, and several through holes are formed near the four corners of each lifting rod. The bottom ends of several limiting rods penetrate the inner cavities of adjacent through holes and are jointly fixedly connected to a base. A fixing block is fixedly connected near the center of the top of the base. A conveyor belt is located to the right of the fixing block, and a five-station cutting, trimming, and rolling pressing station is located to the right of the conveyor belt. A spray cleaning line is located to the right of the five-station cutting, trimming, and rolling pressing station. A first opening is formed near the center of the top of the fixing block, and a groove is formed at the bottom of the inner cavity of the first opening. A blind hole is formed at the bottom of the inner cavity of the groove, and the bottom of the blind hole is fixed... A spring is connected, with a fixing plate fixedly connected to the top of the spring. A support rod is fixedly connected to the top of the fixing plate. The top of the support rod passes through the inner cavity of a blind hole and is fixedly connected to a support block. A lower pressing mold is fixedly connected to the bottom of the lifting rod near the center. A disc is fitted on the outer edge of the lower pressing mold near the center. The mold body is fitted onto the bottom end of the lower pressing mold. A suction cup is fitted to the right side of the mold body near the bottom. A movable rod is fixedly connected to the right side of the suction cup. The bottom end of the movable rod is hinged to the right side wall of the fixing block. A movable piece is hinged to the right side of the movable rod. A connecting shaft is fixedly connected to the center of the movable piece. A through hole is opened on the connecting shaft. A rotating shaft passes through the inner cavity of the through hole. A pull rod is fixedly connected to the outer edge of the rotating shaft near the front end. The pull rod and the top of the movable piece are hinged to the bottom of the lifting rod.

[0005] Preferably, the limiting rods are arranged in a rectangular array with the bottom center of the top plate as the central axis.

[0006] Preferably, the inner cavities of the plurality of through holes are all polished, and the inner cavities of the through holes contain lubricating fluid.

[0007] Preferably, the support block is located near the top of the inner cavity of the first opening, the cross-section of the support block is a T-shaped structure, the top of the T-shaped structure of the support block is longer than the bottom, and the bottom structure of the support block matches the structure of the groove.

[0008] Preferably, the cross-section of the mold body is U-shaped, and the opening of the U-shape of the mold body faces upward.

[0009] Preferably, the cross-section of the movable rod is arc-shaped, and the arc-shaped opening of the movable rod faces the fixed block.

[0010] Preferably, the movable piece is arc-shaped, and the arc-shaped opening of the movable piece faces the downward pressing mold, and the movable piece is elastic.

[0011] An automated stretching line for stainless steel processing includes the following steps:

[0012] S1: First, by placing the mold body on top of the fixed block, start the hydraulic press, and use the power of the hydraulic press to push the lifting rod downward;

[0013] S2: Since the perforated cavities at the four corners of the lifting rod are all through which limit rods pass, the limit rods have a limiting effect on the lifting rod. The lifting rod is pushed by the hydraulic press to push the lower pressure mold fixedly connected to the bottom.

[0014] S3: The lower die moves downward to squeeze the mold body. At this time, the lower die squeezes the mold body into the opening cavity at the top of the fixed block, squeezing the mold body into a U-shaped product.

[0015] S4: At this time, when the material is being ejected, the hydraulic press retracts, pulling the lifting rod upward, which causes the lower die to move the mold body upward. At this time, the movable piece hinged to the lifting rod pulls the movable rods hinged to each other at the bottom upward.

[0016] S5: The upward movement of the movable rod pushes the suction cup to fit against the mold body, and the suction cup adsorbs and fixes the mold body.

[0017] S6: At this time, the hydraulic press continues to move upward, causing the lower die to separate from the die body. The die body is fixed to the left side of the movable rod by the suction cup.

[0018] S7: At this time, when the pressing mold continues to move upward, it pulls the lifting rod to the top. At this time, the lifting rod pulls the movable piece. Since the movable piece is an arc-shaped thin piece, the movable piece is pulled to the left by the pull rod.

[0019] S8: This causes the bending arc of the movable piece to be opposite to its original state. At this time, the movable rod is pushed to the right, so that the movable rod transports the mold body to the top of the conveyor belt, and then the conveyor belt transports the mold body to the subsequent working position for operation.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention enables the equipment to demold without manual intervention, preventing injuries caused by manual demolding errors and improving equipment safety. Furthermore, it reduces manual labor and increases production efficiency. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-5This invention provides a technical solution: an automatic stretching line for stainless steel processing, comprising a hydraulic press 1 and a mold body 7. The mold body 7 has a U-shaped cross-section with the U-shaped opening facing upwards. A top plate 2 is fixedly connected to the top of the hydraulic press 1, and several limiting rods 3 are fixedly connected to the bottom of the top plate 2. The limiting rods 3 are arranged in a rectangular array around the center of the bottom of the top plate 2, serving as limiting rods. A lifting rod 4 is located at the bottom of the top plate 2, and several through holes are provided near the four corners of the lifting rod 4. The inner cavities of the through holes are polished and contain lubricating fluid, serving as limiting rods. The bottom ends of the limiting rods 3 penetrate the inner cavities of adjacent through holes and are fixedly connected to a base 13. A fixing block 10 is fixedly connected to the top of the seat 13 near the center. A conveyor belt 14 is located to the right of the fixing block 10. A five-station cutting and rolling press 21 is located to the right of the conveyor belt 14. A spray cleaning line 22 is located to the right of the five-station cutting and rolling press 21. A first opening is formed at the top of the fixing block 10 near the center. A groove is formed at the bottom of the inner cavity of the first opening. A blind hole is formed at the bottom of the inner cavity of the groove. A spring 12 is fixedly connected to the bottom of the inner cavity of the blind hole. A fixing plate 11 is fixedly connected to the top of the spring 12. A support rod 9 is fixedly connected to the top of the fixing plate 11. The top of the support rod 9 passes through the inner cavity of the blind hole and is fixedly connected to a support block 8. The support block 8 is located near the top of the inner cavity of the first opening. The cross-section of the support block 8 is T-shaped. The top of the T-shaped structure is longer than the bottom, and the bottom structure of the support block 8 matches the structure of the groove, which facilitates demolding. A lower pressure mold 6 is fixedly connected to the bottom of the lifting rod 4 near the center. A disc 5 is fitted onto the outer edge of the lower pressure mold 6 near the center. The mold body 7 is fitted onto the bottom end of the lower pressure mold 6. A suction cup 19 is fitted to the right side of the mold body 7 near the bottom. A movable rod 15 is fixedly connected to the right side of the suction cup 19. The movable rod 15 has an arc-shaped cross-section, and the arc-shaped opening of the movable rod 15 faces the fixed block 10, serving to pull for fixing and demolding. The bottom end of the movable rod 15 is connected to the fixed block 10. The right side walls of the fixed block 10 are hinged to each other. The right side of the movable rod 15 is hinged to a movable piece 17. The movable piece 17 is arc-shaped, and the arc-shaped opening of the movable piece 17 faces the lower pressing mold 6. The movable piece 17 is elastic and plays a role in bending left and right with the pull rod 18 when stretched, so as to pull the movable rod 15 to move. A connecting shaft 16 is fixedly connected to the center of the movable piece 17. A through hole is opened on the connecting shaft 16. The inner cavity of the through hole passes through the rotating shaft 20. The pull rod 18 is fixedly connected to the outer edge of the rotating shaft 20 near the front end. The top of the pull rod 18 and the top of the movable piece 17 are hinged to the bottom of the lifting rod 4.

[0030] An automated stretching line for stainless steel processing includes the following steps:

[0031] S1: First, by placing the mold body 7 on top of the fixed block 10, start the hydraulic press 1, and use the power of the hydraulic press 1 to push the lifting rod 4 downward.

[0032] S2: Since the perforated cavities at the four corners of the lifting rod 4 all pass through the limiting rod 3, the limiting rod 3 has a limiting effect on the lifting rod 4. The lifting rod 4 is pushed by the hydraulic press 1 to push the lower pressure mold 6 fixedly connected at the bottom.

[0033] S3: The lower die 6 moves downward to squeeze the die body 7. At this time, the lower die 6 squeezes the die body 7 into the opening cavity at the top of the fixed block 10, squeezing the die body 7 into a U-shaped product.

[0034] S4: At this time, when the material is being unloaded, the hydraulic press 1 retracts, pulling the lifting rod 4 upward, causing the lower die 6 to drive the die body 7 upward. At this time, the movable piece 17 hinged on the lifting rod 4 pulls the movable rod 15 hinged at the bottom upward.

[0035] S5: The upward movement of the movable rod 15 pushes the suction cup 19 to fit against the mold body 7, and the suction cup 19 adsorbs and fixes the mold body 7.

[0036] S6: At this time, the hydraulic press 1 continues to move upward, causing the lower die 6 to separate from the die body 7. The die body 7 is fixed to the left side of the movable rod 15 by the suction cup 19.

[0037] S7: At this time, when the pressing mold 6 continues to move upward, it pulls the lifting rod 4 to move to the top. At this time, the lifting rod 4 pulls the movable piece 17. Since the movable piece 17 is an arc-shaped thin piece, the movable piece 17 is pulled to the left by the pull rod 18.

[0038] S8: This causes the bending arc of the movable piece 17 to be opposite to its original state. At this time, the movable rod 15 is pushed to move to the right, so that the movable rod 15 transports the mold body 7 to the top of the conveyor belt 14, and then the conveyor belt 14 transports the mold body 7 to the subsequent working position for operation.

[0039] Working principle: First, by placing the mold body 7 on top of the fixed block 10, the hydraulic press 1 is started. The hydraulic press 1 pushes the lifting rod 4 downward. Since the perforated cavities at the four corners of the lifting rod 4 are all pierced by limit rods 3, the limit rods 3 limit the lifting rod 4. The hydraulic press 1 pushes the lifting rod 4 to push the lower die 6 fixedly connected to the bottom. The lower die 6 moves downward to squeeze the mold body 7. At this time, the lower die 6 squeezes the mold body 7 into the opening cavity at the top of the fixed block 10, squeezing the mold body 7 into a U-shaped product. When unloading, the hydraulic press 1 retracts, pulling the lifting rod 4 upward, causing the lower die 6 to drive the mold body 7 upward. At this time, the movable piece 17 hinged to the lifting rod 4 pulls the movable rod 15 hinged to the bottom upward. The upward movement of the movable rod 15 pushes the suction cup 19 to adhere to the mold body 7, and the suction cup 19 adsorbs and fixes the mold body 7. At this time, the hydraulic press 1 continues to move upward, causing the lower die 6 to separate from the mold body 7. The suction cup 19 fixes the mold body 7, making the mold body 7 fixed on the left side of the movable rod 15. At this time, when the lower die 6 continues to move upward, it pulls the lifting rod 4 to move to the top. At this time, the lifting rod 4 pulls the movable piece 17. Since the movable piece 17 is an arc-shaped thin piece, the movable piece 17 is pulled to the left by the pull rod 18, causing the curvature of the movable piece 17 to be opposite to its original state. At this time, the movable rod 15 is pushed to move to the right, so that the movable rod 15 transports the mold body 7 to the top of the conveyor belt 14, and then the conveyor belt 14 transports the mold body 7 to the subsequent working position for operation.
