Description

Positioning device for sheet metal bending Technical Field

[0001] This utility model relates to the field of sheet metal bending technology, specifically to a positioning device for sheet metal bending. Background Technology

[0002] Sheet metal processing is a manufacturing process that includes bending, shearing, punching, cutting, splicing, riveting, and forming. Sheet metal parts are products manufactured through sheet metal processing. The bending and forming of sheet metal are carried out on a bending machine. The workpiece to be formed is placed on the bending machine, and with the help of specific molds or workpieces, the sheet metal is bent. This requires the use of a bending machine.

[0003] Currently, when sheet metal is bent using a bending machine, the areas where the sheet metal needs to be bent are usually marked in advance to determine the bending position. Then, the sheet metal is placed on the bending point of the bending machine, and the alignment of the marked areas and the bending part is directly observed by eye. This method is not only time-consuming, but also has low accuracy due to the lack of positioning of the sheet metal. This can cause the sheet metal to tilt during continuous bending, further reducing the accuracy of the sheet metal bending. Therefore, we propose a positioning device for sheet metal bending.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please refer to Figures 1 to 5. In this embodiment of the present invention, the positioning device for sheet metal bending includes: a machine base 1, a moving mechanism 2 on the front of the machine base 1, a fixing mechanism 3 on the moving mechanism 2, a horizontal groove on the top of the machine base 1, a distance measuring mechanism 4 inside the horizontal groove, a scale line on one side of the top of the horizontal groove, a U-shaped frame 5 connected to the top of the machine base 1, grooves on both sides of the U-shaped frame 5, vertical grooves on both sides of the machine base 1, positioning mechanisms 6 inside the two vertical grooves, and both positioning mechanisms 6 extending to the top of the machine base 1, and locking mechanisms 7 on both sides of the U-shaped frame 5, and the two locking mechanisms 7 being movably connected to the two positioning mechanisms 6 respectively.

[0025] Specifically, first, place both ends of the sheet metal between the top of the machine base 1 and the moving mechanism 2. Then, manually rotate the fixing mechanism 3 to fix the sheet metal. Next, pull the two locking mechanisms 7 upward to remove them from the two positioning mechanisms 6. At this time, the two positioning mechanisms 6 will reset and rest against both sides of the sheet metal. Then, start the moving mechanism 2 to move the fixed sheet metal. The two positioning mechanisms 6 can limit the movement of the sheet metal to prevent deviation during movement. During the movement of the sheet metal, it will squeeze the measuring mechanism 4 for compression. While the measuring mechanism 4 is compressed, the scale line can be observed to know the distance the measuring mechanism 4 has moved, thus knowing the distance the sheet metal has moved. When the sheet metal has moved the specified distance, close the moving mechanism 2 to lower the upper film and squeeze the sheet metal to complete the precise bending of the sheet metal.

[0026] Example 2:

[0027] Please refer to Figures 2-4. In this embodiment of the present invention, the positioning device for sheet metal bending, the moving mechanism 2 includes a connecting frame 201, a first threaded rod 202, a first threaded block 203, a motor 204, and a placement platform 205. The connecting frame 201 is connected to the front of the machine base 1. The first threaded rod 202 is rotatably connected to the inside of the connecting frame 201. The first threaded block 203 is threaded to the outer surface of the first threaded rod 202. The motor 204 is connected to the front of the connecting frame 201, and one end of the first threaded rod 202 extends to the front of the connecting frame 201 and is connected to one end of the output shaft of the motor 204. The placement platform 205 is connected to the top of the first threaded block 203, and a connecting groove is provided on the back of the placement platform 205. The fixing mechanism 3... The system includes a second threaded rod 301, a handle 302, a second threaded block 303, and a fixing plate 304. The second threaded rod 301 is rotatably connected between the top and bottom of the inner wall of the connecting groove, and the top end of the second threaded rod 301 extends to the top of the placement platform 205. The handle 302 is connected to the top end of the second threaded rod 301. The second threaded block 303 is threadedly connected to the outer surface of the second threaded rod 301. The fixing plate 304 is connected to the back of the second threaded block 303. The ranging mechanism 4 includes a slider 401, a return spring 402, and a ranging plate 403. The slider 401 is slidably connected to the inner wall of the transverse groove. The return spring 402 is connected between one side of the inner wall of the transverse groove and the back of the slider 401. The ranging plate 403 is connected to the top of the slider 401.

[0028] Specifically, the two ends of the sheet metal are placed on the top of the machine base 1 and the placement table 205 respectively. The handle 302 is turned to drive the second threaded rod 301 to rotate, causing the second threaded block 303 to descend and fix the sheet metal. The output shaft of the motor 204 is started to drive the first threaded rod 202 to rotate, so that when the first threaded block 203 moves, it moves the fixed sheet metal through the placement table 205. Then, one end of the sheet metal will press the measuring plate 403, causing the measuring plate 403 to drive the slider 401 to slide inside the transverse groove and compress the return spring 402. During this process, the distance that the measuring plate 403 moves next to the scale line can be observed. After the sheet metal moves a specified distance, the motor 204 will be turned off. Finally, the sheet metal is pressed by the upper film to complete the precise bending of the sheet metal. After the sheet metal is bent, it is taken out, and the return spring 402 will extend to drive the slider 401 to return to its original position, so that the slider 401 can measure the distance of the sheet metal movement next time.

[0029] Example 3:

[0030] Please refer to Figure 5. In this embodiment of the present invention, the positioning device for sheet metal bending includes a positioning mechanism 6 comprising a spring telescopic rod 601, an L-shaped plate 602, two rubber rollers 603, and a slot 604. The spring telescopic rod 601 is connected to one side of the inner wall of one of the vertical grooves. The lower part of one side of the L-shaped plate 602 is connected to one end of the spring telescopic rod 601. Both rubber rollers 603 are rotatably connected to the top of the inner wall of the L-shaped plate 602. The slot 604 is opened at the top of the L-shaped plate 602. The U-shaped frame 701 includes a U-shaped frame 701 and an insert 702. The U-shaped frame 701 is connected to one side of the U-shaped frame 5. The insert 702 is slidably connected inside the U-shaped frame 701, and one end of the insert 702 is movably inserted into the inside of the slot 604.

[0031] Specifically, after the sheet metal is positioned between the two sides of the inner wall of the U-shaped frame 5, the insert block 702 is pulled upward and slides upward inside the loop frame 701, and is withdrawn from the inside of the slot 604, releasing the lock on the L-shaped plate 602. The spring telescopic rod 601 will reset and retract, driving the L-shaped plate 602 closer to one side of the machine base 1, so that the two rubber rollers 603 abut against one side of the sheet metal, and cooperate with another positioning mechanism 6 to fix the two sides of the sheet metal. When the sheet metal moves, the two rubber rollers 603 can limit the sheet metal to avoid the sheet metal from shifting during movement.

[0032] The working principle of this utility model is as follows: When sheet metal needs to be bent, firstly, one end of the sheet metal is placed on the bending groove at the top of the machine tool 1, so that one end of the sheet metal is in contact with the front of the measuring plate 403, and the other end is placed on the placement table 205. Then, the operator turns the handle 302 to drive the second threaded rod 301 to rotate, thereby causing the second threaded block 303 to descend on the outer surface of the second threaded rod 301, which in turn drives the fixing plate 304 to descend, pressing against the top of the sheet metal to fix it. Then, the motor 204 is started, and the output shaft of the motor 204 drives the first threaded rod 202 to rotate, thereby causing the first threaded block 203 to move on the outer surface of the first threaded rod 202, which in turn drives the placement table 205 to move closer to the front of the machine tool 1, thereby moving the fixed sheet metal. Then, one end of the sheet metal will press against the measuring plate 403 to move. When the measuring plate 403 moves... By observing the scale lines, one can know how far the sheet metal has moved. At the same time, the measuring plate 403 will drive the slider 401 to slide inside the transverse groove, thereby squeezing the return spring 402 for compression. After the sheet metal has moved a specified distance, the motor 204 will shut off. At this time, the sheet metal can be squeezed by the upper film to complete the precise bending of the sheet metal. When the moving mechanism 2 is conveying the sheet metal, when the sheet metal is between the two sides of the inner wall of the U-shaped frame 5, the insert block 702 can be pulled upward. The insert block 702 slides upward inside the loop frame 701, thereby withdrawing from the inside of the slot 604 and releasing the lock on the L-shaped plate 602. At this time, the spring telescopic rod 601 will reset, driving the L-shaped plate 602 closer to one side of the machine base 1, so that the two rubber rollers 603 abut against one side of the sheet metal. Finally, when the sheet metal moves, the rubber rollers 603 can limit the sheet metal to prevent it from deviating during the movement.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
