Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a support device for the lower die of a bending machine. Background Technology

[0002] In sheet metal production and processing equipment, bending machines are important equipment for forming angles in metal sheets. They are widely used in industries such as machinery manufacturing, automotive industry, aerospace and home appliance production. The upper and lower dies are key components of the bending machine body and can be disassembled and replaced. The lower part of the bending machine body is equipped with a base to support the lower die, which plays an important role in supporting the workpiece and cooperating with the upper die to complete the bending action.

[0003] The support base for the lower die of existing bending machines is usually fixed. When installing the lower die, it is inserted into the guide rail on the support base from the side. However, since the lower die is made of a relatively thick metal plate, it is quite heavy. Moreover, the distance between the fixed upper die and the support base is narrow, making it inconvenient to pick up the lower die for horizontal insertion. Hands are prone to touching the hard bottom of the upper die and getting injured. This makes the entire installation operation of the lower die complicated and laborious, affecting work efficiency.

[0004] Therefore, in view of the problems that the support base of the lower die of the existing bending machine is fixed, the side horizontal insertion installation of the heavy lower die is relatively laborious, and it is restricted by the fixed upper die, which can easily cause the hand to touch the hard bottom of the upper die and cause injury, resulting in low efficiency of the entire installation work, a lower die support device for the bending machine can be designed. Utility Model Content

[0005] In order to overcome the problems of the fixed support base of the lower die of the existing bending machine, the side horizontal insertion installation of the heavy lower die is laborious and restricted by the fixed upper die, which can easily cause the hand to be injured by touching the hard bottom of the upper die, and the overall installation work is inefficient.

[0006] The technical solution of this utility model is as follows: a lower die support device for a bending machine, including a base; it also includes a mounting seat and a rotating column. Support seats are symmetrically fixedly connected to the upper left and right sides of the base. A receiving seat is fixedly connected to the upper end of the two support seats. A mounting seat is provided at the upper end of the receiving seat. The lower die body is provided at the upper end of the mounting seat. A rotating column is fixedly connected to the middle side of the bottom of the mounting seat. A through hole is opened in the middle of the receiving seat. The bottom of the rotating column passes through the through hole and is rotatably connected to the surface of the base. Positioning holes are symmetrically opened on the left and right sides of the bottom of the mounting seat. Two through holes corresponding to the positions of the positioning holes are opened on the surface of the receiving seat. Two lifting plates are provided at the upper end of the base. A lifting mechanism for controlling the lifting movement of the two lifting plates is provided between the base and the receiving seat. A telescopic rod is fixedly connected to the upper end of the two lifting plates. A spring is sleeved on the outer side of the telescopic rod. A positioning column is fixedly connected to the upper end of the telescopic rod. The positioning column is located between the two connected positioning holes and the through hole, and the side of the positioning column is set as an inclined curved surface.

[0007] Preferably, the mounting base is rotated counterclockwise by rotating the rotating column to a suitable angle, which facilitates the insertion and installation of the lower mold body to be assembled on the mounting base. Then, the lifting plate is lifted by the lifting mechanism, so that the tops of the two positioning columns pass through the second perforation and protrude to the surface of the receiving base. Then, the mounting base is rotated back to its original position. Through the action of the telescopic rod and spring, the positioning columns first retract into the second perforation and then insert upward into the positioning hole, completing the alignment and positioning of the mounting base.

[0008] Preferably, a lifting ring is movably sleeved on the outer side of the rotating column, and two lifting plates are symmetrically fixedly connected to the left and right sides of the lifting ring.

[0009] Preferably, the lifting mechanism includes a threaded post; the threaded post is rotatably connected between the right side of the base and the receiving seat, and the right lifting plate is threadedly connected to the outside of the threaded post.

[0010] Preferably, the lifting mechanism also includes a turntable and grips; the turntable is fixedly connected to the outer side of the upper end of the threaded column, and four grips are symmetrically fixedly connected to the outer side of the turntable.

[0011] Preferably, the lifting mechanism also includes a guide column; the guide column is fixedly connected between the left side of the base and the receiving seat, and the left lifting plate is movably sleeved on the outside of the guide column.

[0012] Preferably, the mounting base has slots at both ends, and a limiting block is slidably disposed in the slot.

[0013] Preferably, the upper left and right sides of the receiving seat are provided with grooves, and a threaded post II is rotatably connected in the groove. A movable block is threadedly connected to the outer side of the threaded post II. The movable block is fixedly connected to the bottom of the corresponding limiting block. Two knobs are rotatably connected to the surface of the receiving seat. The two knobs are fixedly connected to the two corresponding threaded posts II respectively.

[0014] Preferably, the upper end of the mounting base is fixedly connected to an inverted trapezoidal positioning guide rail, and the lower side of the lower mold body is provided with an inverted trapezoidal positioning groove adapted to the insertion of the inverted trapezoidal positioning guide rail.

[0015] The beneficial effects of this utility model are:

[0016] The device features a rotatable mounting base on the receiving seat, allowing the mounting base to rotate at a suitable angle. The lower die body is then inserted and installed from the front of the bending machine. The lifting mechanism adjusts the height of the lifting plate, and in conjunction with the telescopic rod and spring, the positioning pin is automatically inserted into the bottom of the mounting base for quick and accurate positioning. This rapid installation method avoids the traditional side-insertion method, saving time and effort, and is easy to operate. It also prevents hand injuries from contact with the hard bottom of the upper die, thus improving installation efficiency. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-6 This utility model provides an embodiment of a bending machine lower die support device, including a base 1; it also includes a mounting base 4 and a rotating column 6. Support seats 2 are symmetrically fixedly connected to the upper left and right sides of the base 1. Support seats 3 are fixedly connected to the upper ends of the two support seats 2. The mounting base 4 is located at the upper end of the support seats 3. The lower die body 5 is located at the upper end of the mounting base 4. The rotating column 6 is fixedly connected to the middle of the bottom of the mounting base 4. A through hole 7 is provided in the middle of the support seat 3. The bottom of the rotating column 6 passes through the through hole 7 and is rotatably connected to the surface of the base 1. Positioning holes 8 are symmetrically provided on the left and right sides of the bottom of the mounting base 4. Two through holes 9 corresponding to the positions of the positioning holes 8 are provided on the surface of the support seat 3. Two lifting plates 11 are provided at the upper end of the base 1, and a mechanism for controlling the lifting movement of the two lifting plates 11 is provided between the base 1 and the support seat 3. The lifting mechanism has two lifting plates 11 with telescopic rods 12 fixedly connected to their upper ends. A spring 13 is sleeved on the outside of the telescopic rod 12. A positioning post 15 is fixedly connected to the upper end of the telescopic rod 12. The positioning post 15 is set between two connected positioning holes 8 and through hole 9. The side of the positioning post 15 is set as an inclined curved surface. By rotating the post 6, the mounting base 4 is rotated counterclockwise to a suitable angle, so that the lower mold body 5 to be assembled can be inserted and installed on the mounting base 4. Then, the lifting mechanism lifts the lifting plates 11, so that the tops of the two positioning posts 15 pass through through hole 9 and protrude to the surface of the receiving base 3. Then, the mounting base 4 is rotated back to its original position. Through the action of the telescopic rod 12 and the spring 13, the positioning post 15 first retracts into through hole 9 and then inserts upward into the positioning hole 8, completing the alignment and positioning of the mounting base 4.

[0026] Please see Figure 1 and Figure 5In this embodiment, a lifting ring 14 is movably sleeved on the outer side of the rotating column 6. Two lifting plates 11 are symmetrically fixedly connected to the left and right sides of the lifting ring 14. The height of the two lifting plates 11 can be adjusted by adjusting the lifting ring 14 to rise or fall. The lifting mechanism includes a threaded column 1001. The right side of the base 1 and the receiving seat 3 are rotatably connected to the threaded column 1001. The right lifting plate 11 is threadedly connected to the outer side of the threaded column 1001. Rotating the threaded column 1001 can drive the right lifting plate 11 to move up and down, and then drive the other lifting plate 11 to move up and down through the lifting ring 14. The lifting mechanism also includes... Turntable 1002 and handles 1003; Turntable 1002 is fixedly connected to the outer side of the upper end of threaded column 1001, and four handles 1003 are symmetrically fixedly connected to the outer side of turntable 1002. The threaded column 1001 is rotated by driving turntable 1002. The handles 1003 are convenient and easy to operate to rotate turntable 1002. The lifting mechanism also includes guide column 1004; Guide column 1004 is fixedly connected between the left side of base 1 and bearing seat 3. The left lifting plate 11 is movably sleeved on the outer side of guide column 1004. When lifting plate 11 moves up and down, guide column 1004 plays a role in stabilizing and guiding.

[0027] Please see Figure 2 , Figure 3 , Figure 4 and Figure 6 In this embodiment, the mounting base 4 has slots 16 at both ends, and a limiting block 17 is slidably disposed in the slots 16. After the mounting base 4 with the lower mold body 5 installed is aligned, the limiting block 17 is inserted into the slot 16 of the mounting base 4 to fix the position of the mounting base 4 in conjunction with the receiving base 3. The upper end of the receiving base 3 has grooves 18 on both the left and right sides, and a threaded post 19 is rotatably connected in the grooves 18. A moving block 20 is threadedly connected to the outer side of the threaded post 19. The moving block 20 is fixedly connected to the bottom of the corresponding limiting block 17. Two knobs 21 are rotatably connected to the surface of the receiving base 3. 21 is fixedly connected to two corresponding threaded post 19. The drive knob 21 drives the threaded post 19 to rotate, and the threaded post 19 pushes the moving block 20 to move, thereby pushing the limiting block 17 into the slot 16 in the mounting base 4 to fix its position. The upper end of the mounting base 4 is fixedly connected to the inverted trapezoidal positioning guide rail 23. The lower mold body 5 has an inverted trapezoidal positioning groove 22 adapted to the insertion of the inverted trapezoidal positioning guide rail 23. Through the cooperation of the inverted trapezoidal positioning guide rail 23 and the inverted trapezoidal positioning groove 22, the lower mold body 5 is installed on the surface of the mounting base 4 to achieve quick installation and prevent accidental fall-off.

[0028] During installation, the mounting base 4 is rotated counterclockwise by rotating column 6 to a suitable angle. The inverted trapezoidal positioning groove 22 and inverted trapezoidal positioning guide rail 23 cooperate to facilitate the insertion and installation of the lower mold body 5 onto the mounting base 4. Then, through the lifting mechanism, the lever 1003 is operated to drive the turntable 1002, which in turn drives the threaded column 1001 to rotate. The threaded column 1001 drives the right-side lifting plate 11 to lift upwards. Then, through the lifting ring 14, the other lifting plate 11 is driven to lift upwards, thus lifting both... The top of the positioning pin 15 passes through the second perforation 9 and protrudes onto the surface of the receiving seat 3. Then, the mounting seat 4 is rotated back to its original position. Through the cooperation of the telescopic rod 12 and the spring 13, the positioning pin 15 first retracts into the second perforation 9 and then inserts upward into the positioning hole 8, completing the alignment and positioning of the mounting seat 4. Finally, the drive knob 21 drives the threaded pin 19 to rotate, and the threaded pin 19 pushes the moving block 20 to move, thereby pushing the limiting block 17 into the slot 16 in the mounting seat 4 to fix its position, completing the installation operation.

[0029] Through the above steps, the device is equipped with a rotatable mounting base 4 on the receiving seat 3, which can rotate the mounting base 4 at a suitable angle. The lower mold body 5 is inserted and installed from the front facing the entire bending machine. Then, the height of the lifting plate 11 is adjusted by the lifting mechanism. Working with the telescopic rod 12 and spring 13, the positioning column 15 is automatically inserted into the bottom of the mounting base 4 to achieve quick and accurate positioning and complete the installation quickly. This avoids the traditional side-mounted horizontal insertion method, saving time and effort, and making the operation convenient. It also avoids hand injuries from touching the hard bottom of the upper mold, improving the efficiency of the installation work. This solves the problem that the support base 2 of the lower mold of the existing bending machine is fixed, and the side-mounted horizontal insertion of the heavy lower mold is laborious and restricted by the fixed upper mold, which easily causes hand injuries from touching the hard bottom of the upper mold, resulting in low overall installation efficiency.
