Description

Technical Field

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

[0002] Currently, most simple sheet metal bending devices are hand-cranked, moving the upper die downwards and bending the sheet metal through the cooperation of the upper and lower dies. For example, a simple bending machine disclosed in Chinese Patent Publication No. CN216369626U. However, because the height of the hand crank on the bending device is fixed and cannot be adjusted according to the user's height, users of different heights cannot rotate the hand crank in a comfortable posture. This makes the bending device inconvenient to use. At the same time, since the downward movement distance of the upper die is controlled only by the user's experience, inexperienced users cannot accurately control the degree of bending of the sheet metal. Furthermore, during bending, the sheet metal often moves, resulting in inaccurate bending position. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, such as: currently, because the height of the hand crank on the bending device is fixed and cannot be adjusted according to the user's height, users of different heights cannot rotate the hand crank in a comfortable posture, which makes the bending device less convenient to use. At the same time, because the downward movement distance of the upper die is controlled only by the user's experience, inexperienced users cannot accurately control the bending degree of the sheet metal. Moreover, during bending, the bending position of the sheet metal is often inaccurate due to the movement of the sheet metal. Therefore, a simple sheet metal processing bending device is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A simple sheet metal bending device includes a base, a box body fixedly connected to the upper surface of the base, a guide post fixedly connected to the upper surface of the box body, a lower die base fixedly connected to the upper surface of the box body, a lower die fixedly connected to the upper surface of the lower die base, a bending mechanism fitted to the surface of the guide post, a second circular hole opened on the upper surface of the box body, adjusting brackets fixedly connected to the inner wall of the second circular hole and the front and rear sides of the bending mechanism, a third circular hole opened on the upper surface of the box body, a hand crank bracket fixedly connected to the inner wall of the third circular hole, and a ring chain sleeved on the surface of the hand crank bracket and the surface of the adjusting bracket.

[0006] Preferably, the bending mechanism includes a support member, the front and rear sides of which are fixedly connected to the surface of the adjusting bracket. A first circular hole is provided inside the support member. A first bearing is fixedly connected to the inner wall of the first circular hole. A first threaded cylinder is fixedly connected to the inner wall of the first bearing. A first threaded post is threadedly connected to the first threaded cylinder. An upper die base is fixedly connected to the bottom of the first threaded post. An upper die is fixedly connected to the bottom of the upper die base. A first hollow block is fixedly connected to the front and rear sides of the upper die base. A linear bearing is fixedly connected to the inner wall of the first hollow block. The inner wall of the linear bearing is in contact with the surface of the guide post. A turntable is fixedly connected to the surface of the first threaded cylinder.

[0007] Preferably, the adjusting bracket includes a second threaded cylinder, and a second hollow block is fixedly connected to the surface of the second threaded cylinder and the front and rear sides of the support member. A second threaded post is threadedly connected to the inner wall of the second threaded cylinder. A second bearing is fixedly connected to the surface of the second threaded post and the inner wall of the second circular hole. A first sprocket is fixedly connected to the surface of the second threaded post, and the surface of the first sprocket is sleeved with the inner wall of the annular chain.

[0008] Preferably, the hand-cranked bracket includes a hand-cranked component, the inner wall of which is fixedly connected to a cylinder, the surface of which and the inner wall of which are both fixedly connected to a third bearing, the surface of which is fixedly connected to a second sprocket, and the surface of which is sleeved with the inner wall of the annular chain.

[0009] Preferably, a strip block is fixedly connected to the upper surface of the box body, and a rubber strip is adhered to the upper surface of the strip block.

[0010] Preferably, a sliding sleeve is fitted to the surface of the guide post, and a threaded hole is provided on the left side of the sliding sleeve. A fixing bolt is threaded to the inner wall of the threaded hole, and the surface of the fixing bolt is in contact with the surface of the guide post.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model is provided with a box body, a second circular hole, an adjusting bracket, a third circular hole, a hand crank bracket and an annular sprocket. When the user rotates the hand crank on the hand crank bracket, the second sprocket is rotated by the hand crank. Through the cooperation of the first sprocket, the second sprocket and the annular chain, the second threaded column on the adjusting bracket is rotated. At this time, through the cooperation of the second threaded column and the second threaded cylinder, the height of the turntable on the bending mechanism can be changed. Thus, when the user uses the bending device, the turntable can be adjusted to a suitable position according to his / her own height, making it more convenient for the user to use the bending device.

[0013] (2) This utility model sets a strip hole and a rubber strip. When the plate is placed on the lower die, the rubber strip will contact the plate. Through the friction between the rubber strip and the plate, the plate is not easy to move on the lower die, thereby preventing the plate from moving and causing inaccurate bending position when bending the plate. At the same time, the sliding sleeve can be fixed on the guide post by the cooperation of the threaded hole and the fixing bolt. After the sliding sleeve is fixed on the guide post, the downward movement of the upper die can be restricted by the sliding sleeve, thereby enabling the user to accurately control the bending degree of the plate.

[0027] The bending mechanism 6 includes a support member 601. Both the front and rear sides of the support member 601 are fixedly connected to the surface of the adjusting bracket 8. A first circular hole 602 is formed inside the support member 601. A first bearing 603 is fixedly connected to the inner wall of the first circular hole 602. A first threaded cylinder 604 is fixedly connected to the inner wall of the first bearing 603. The first threaded cylinder 604 is fixed within the first circular hole 602 by the first bearing 603, allowing it to rotate freely within the hole. A first threaded post 605 is threadedly connected to the first threaded cylinder 604. The bottom of the first threaded post 605 is fixedly connected to... The upper mold base 606 has an upper die 607 fixedly connected to its bottom. The front and rear sides of the upper mold base 606 are fixedly connected to a first hollow block 608. The inner wall of the first hollow block 608 is fixedly connected to a linear bearing 609. The inner wall of the linear bearing 609 is in contact with the surface of the guide post 3. Through the cooperation of the linear bearing 609 and the guide post 3, the upper mold base 606 can only move up and down. The surface of the first threaded cylinder 604 is fixedly connected to a turntable 610. When the turntable 610 rotates, the upper die 607 moves up or down through the cooperation of the first threaded cylinder 604 and the first threaded post 605.

[0028] The adjusting bracket 8 includes a second threaded cylinder 801. Second hollow blocks 802 are fixedly connected to the surface of the second threaded cylinder 801 and the front and rear sides of the support member 601. A second threaded post 803 is threadedly connected to the inner wall of the second threaded cylinder 801. A second bearing 804 is fixedly connected to the surface of the second threaded post 803 and the inner wall of the second circular hole 7. The second threaded post 803 is fixed to the second circular hole 7 by the second bearing 804, and the second threaded post 803 can rotate freely. When the second threaded post rotates, the support member 601 moves up or down through the cooperation of the second threaded post 803 and the second threaded cylinder 801. A first sprocket 805 is fixedly connected to the surface of the second threaded post 803. The surface of the first sprocket 805 is sleeved with the inner wall of the annular chain 11.

[0029] The hand-cranked bracket 10 includes a hand-cranked component 1001. A cylinder 1002 is fixedly connected to the inner wall of the hand-cranked component 1001. A third bearing 1003 is fixedly connected to both the surface of the cylinder 1002 and the inner wall of the third circular hole 9. The cylinder 1002 is fixed in the third circular hole 9 by the third bearing 1003, allowing the cylinder 1002 to rotate freely. A second sprocket 1004 is fixedly connected to the surface of the cylinder 1002. The surface of the second sprocket 1004 is sleeved with the inner wall of the annular chain 11. When the hand-cranked component 1001 rotates, the second sprocket 1004 rotates through the hand-cranked component 1001. Through the cooperation of the first sprocket 805, the second sprocket 1004, and the annular chain 11, the second threaded column 803 rotates.

[0030] Example 2:

[0031] Reference Figure 1-3 A strip block 12 is fixedly connected to the upper surface of the box body 2. A rubber strip 13 is adhered to the upper surface of the strip block 12. When the board is placed on the lower die 5, the rubber strip 13 will contact the board. Through the friction between the rubber strip 13 and the board, the board is not easy to move on the lower die 5, thereby preventing the bending position from being inaccurate due to the movement of the board when bending the board.

[0032] Example 3:

[0033] Reference Figure 1-8 A sliding sleeve 14 is fitted onto the surface of the guide post 3. A threaded hole 15 is provided on the left side of the sliding sleeve 14. A fixing bolt 16 is threaded onto the inner wall of the threaded hole 15. The surface of the fixing bolt 16 contacts the surface of the guide post 3. Through the cooperation of the threaded hole 15 and the fixing bolt 16, the sliding sleeve 14 can be fixed on the guide post 3. After the sliding sleeve 14 is fixed on the guide post 3, the downward movement of the upper die 607 can be restricted by the sliding sleeve 14, thereby enabling the user to accurately control the bending degree of the sheet metal.

[0034] In this invention, when using the bending device, the user first rotates the hand crank 1001 to rotate the second sprocket 1004. Through the cooperation of the first sprocket 805, the second sprocket 1004, and the annular chain 11, the second threaded post 803 rotates. Then, through the cooperation of the second threaded post 803 and the second threaded cylinder 801, the height of the support member 601 can be changed. At this time, the user can adjust the position of the support member 601 according to their own height. When the support member 601 moves to the designated position, the user stops rotating the hand crank 1001. The self-locking property between the second threaded cylinder 801 and the second threaded post 803 prevents the position of the support member 601 from changing. Then, by rotating the fixing bolt 16, the fixing bolt 16 is separated from the guide post 3. Finally, the sliding sleeve 14 is moved to the designated position. The upper die 607 is placed on the lower die 5 and the lower die 5 is bent by rotating the turntable 610. The upper die 607 moves downward through the cooperation of the first threaded column 605 and the first threaded column 604. The lower die 5 is bent by the cooperation of the upper die 607 and the lower die 5. The lower die 607 moves downward through the cooperation of the upper die 607 and the lower die 5. The lower position of the upper die 607 is restricted by the sliding sleeve 14. After the plate is bent, the upper die 607 moves upward through the cooperation of the first threaded column 604 and the first threaded column 605 by rotating the turntable 610. After the upper die 607 moves to the initial position, the bent plate is removed from the bending device.
