Description

Technical Field

[0001] The utility model relates to the technical field of plate and sheet metal, in particular to a positioning structure for a stainless steel bending machine. Background Art

[0002] In the sheet metal industry, when bending stainless steel, plate bending machines are usually used to bend the plates. However, for some smaller factories, the overall cost of general CNC bending machines and their supporting equipment is relatively high, and common hydraulic bending machines or manual bending machines are usually used. When using, the user can hold the steel plate and put it on the bending machine workbench, so that the specified bending position of the steel plate is located below the bending tool, and then wait for the bending tool on the bending machine to press down, so that the bending tool presses the specified position of the steel plate into the V groove to bend the plate. However, the bending machine can bend the plate by a small amplitude. , so that the plate is bent into an arc shape. Usually, the designated position of the plate is placed under the bending tool during operation, and then the bending tool is pressed down. Then the user lifts the plate slightly as needed to prevent the bent portion of the plate from forming too large an angle. Then the bending tool is lifted up and the plate is fed in. By folding the plate at multiple locations with more suitable angles, the plate is formed into an arc shape. However, this method requires the user to frequently manually control the distance the plate is fed into the bending machine, and frequently manually control the lifting angle of the plate. If the control is wrong, the plate is easily bent excessively, which is inconvenient and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In an embodiment of the utility model, a positioning structure for a stainless steel bending machine includes a U-shaped frame 100, a moving mechanism 400 is arranged between the two arms of the U-shaped frame 100, and a fixed plate 110 is fixedly connected between the two arms of the U-shaped frame 100, the moving mechanism 400 is located above the fixed plate 110, and a bending mechanism 300 is arranged below the fixed plate 110.

[0022] Specifically, the bending mechanism 300 includes a cylinder 310, a circular hole 112 is opened in the center of the bottom surface of the fixed plate 110, and the cylinder 310 is fixedly connected to the bottom surface of the fixed plate 110, and the movable end of the cylinder 310 is located inside the circular hole 112. When in use, by placing the U-shaped frame 100 next to the bending machine, the height of the fixed plate 110 is equal to the height of the machine body workbench. When in use, the steel plate is placed in the moving mechanism 400 and the moving distance of the stainless steel plate is adjusted. After moving to a suitable distance and starting the bending machine, the user can start the cylinder 310 to make the cylinder 310 push the stainless steel plate to bend, so that the bending angle of the stainless steel plate can be automatically adjusted by the cylinder 310, which is convenient for the user to use the bending machine to perform arc bending on the stainless steel plate.

[0023] Embodiment 1

[0024] like Figure 1-3As shown, in this embodiment, a groove 111 is provided on the top surface of the fixed plate 110, and an insert plate 330 is movably embedded in the groove 111, a guide groove 331 is provided on the top surface of the insert plate 330, and the moving mechanism 400 is slidably engaged with the inside of the guide groove 331, the movable end of the cylinder 310 is fixedly connected to the head 320, and the top of the head 320 is a hemispherical structure, and the length of the insert plate 330 is equal to the length of the groove 111.

[0025] In this embodiment, when in use, the stainless steel plate is fixed on the moving mechanism 400. When the cylinder 310 is pushed, the cylinder 310 first drives the push head 320 to push the panel 330 to drive the moving mechanism 400 to bend the stainless steel plate. When stainless steel plates of different sizes are bent, they are always evenly stressed by the panel 330, which prevents the push head 320 from pushing the stainless steel plate out of the depression. At the same time, the hemispherical push head 320 allows the push head 320 to slide better on the panel 330.

[0026] like Figure 1-3 As shown, in this embodiment, a stabilizing frame 200 is fixedly connected to the bottom end of one side of the U-shaped frame 100 .

[0027] In specific implementation, the stabilizing frame 200 is U-shaped, and the two arms of the stabilizing frame 200 are connected to the bottom ends of the two arms of the U-shaped frame 100, so that one side of the stabilizing frame 200 is close to the ground, thereby increasing the contact area between the U-shaped frame 100 and the ground and improving the stability of the U-shaped frame 100.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, the moving mechanism 400 includes two U-shaped plates 410, and the bottom surfaces of the two U-shaped plates 410 are both slidably clamped inside the guiding groove 331. U-shaped frames 420 are arranged between the two arms of the two U-shaped plates 410, and two rollers 421 are rotatably connected between the two arms of the two U-shaped frames 420. A transmission belt 422 is rotatably sleeved between the outer side walls of the two rollers 421 on the same U-shaped frame 420. Card slots 412 are formed on one side of the two U-shaped plates 410, and blocks 440 are slidably clamped inside the two card slots 412. A driving motor 441 is fixedly connected to one side of each of the two blocks 440, and the motor ends of the two driving motors 441 penetrate through one side of the adjacent block 440. The motor ends of the two driving motors 441 are fixedly connected to one end of an adjacent roller 421. Screws 430 are rotatably connected to the top surfaces of the two U-shaped frames 420, and threaded holes 411 are formed on the top surfaces of the two U-shaped plates 410. The outer side walls of the two screws 430 are screwed with the inner side walls of the adjacent threaded holes 411. By placing the stainless steel plate between the two moving mechanisms 400, and the inner bottom surfaces of the U-shaped plates 410 on the two moving mechanisms 400 are on the same plane as the workbench. When in use, place both sides of the stainless steel plate on the inner bottom surfaces of the two U-shaped plates 410, and then rotate the two screws 430 to drive the two U-shaped frames 420 to move downward, so that the two transmission belts 422 press the stainless steel plate. Then start the two driving motors 441, so that the two driving motors 441 drive the adjacent transmission belts 422 to rotate through the adjacent rollers 421, thereby driving the pressed stainless steel plate to move towards the bending machine, so that the moving distance of the stainless steel plate can be automatically adjusted.

[0030] As Figure 1-4 shown, in this embodiment, sliding grooves 101 are formed on the top surface of the U-shaped frame 100, and sliders 450 are slidably clamped inside the two sliding grooves 101. The two sliders 450 are respectively located above the two U-shaped plates 410, and a plurality of plate chains 451 are fixedly connected between the bottom surfaces of the two sliders 450 and the top surfaces of the adjacent U-shaped plates 410. A plurality of anti-slip grooves 423 are evenly formed on the outer side walls of the two transmission belts 422.

[0031] In specific implementation, due to the structural limitation of the plate chain 451 itself, it can only bend towards its relative two sides. Through the limitation of the plate chain 451, the user can drive the adjacent U-shaped plate 410 to slide in the adjacent sliding groove 101 along with the adjacent slider 450 by拨动 the plate chain 451, which is convenient for the user to adjust the position of the U-shaped plate 410. And after the machine body finishes bending the steel plate, both opposite inner side walls of the groove 111 are arc-shaped surfaces. The embedded plate 330 can fall due to its own weight, and at the same time, the plate chain 451 also naturally hangs down due to its own weight, so that the embedded plate 330 is embedded into the groove 111, completing the reset of the steel plate. Then, the position of the steel plate can be adjusted again through the drive motor 441. Through the anti-slip groove 423, the drive belt 422 is not easy to slide on the steel plate when the steel plate is bent.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.
