Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel bending, in particular to a steel plate bending mechanism. Background Art

[0002] The surface of stainless steel plate is smooth, with high plasticity, toughness and mechanical strength, and is resistant to corrosion by acids, alkaline gases, solutions and other media. The stainless steel plate bending device is a device specially used to bend stainless steel plates into a specific angle or arc. It usually uses the action of force to rearrange the molecules on the stainless steel plate and change its original shape to achieve the purpose of bending. When operating the stainless steel bending device, you first need to check whether the equipment is operating normally, including the bed, pressure head, hydraulic system and other parts to ensure that the equipment is in good condition. Then, measure the size of the stainless steel material to be processed and put it on the pressure head of the bending device. Adjust the mold and bending angle according to the processing requirements. Finally, start the equipment and feed the stainless steel material into the bending device to complete the bending process.

[0003] For example, the Chinese patent "CN217315280U" discloses a steel plate bending mechanism, which proposes: the bottom of the device base is provided with supporting feet, the device vertical plates are provided with two groups, the two groups of device vertical plates are provided on the two sides of the device base, the device top plate is provided at the top of the two groups of device vertical plates, the distance adjustment structure is provided in the device base, the angle adjustment structure is provided on the distance adjustment structure, the clamping structure is provided with two groups, one group of the clamping structure is provided on the distance adjustment structure, the other group of the clamping structure is provided on the angle adjustment structure, and the bending structure is provided at the bottom of the device top plate. The utility model relates to the technical field of stainless steel bending, and specifically provides a stainless steel bending device with a reasonable and simple structure, which is convenient for fixing and clamping stainless steel pipes of different diameters and convenient for adjusting the bending angle.

[0004] In the process of bending stainless steel plates, the existing stainless steel bending device needs to manually hold the stainless steel plate and place it above the right-angle groove to operate the pressure plate to bend it. Due to the overall weight of the stainless steel plate, it is easy to cause deviation and shaking, resulting in uneven placement and bending on a non-horizontal line. In addition, it is easy to cause scratches when manually holding and bending thinner stainless steel plates. During the bending process, the stainless steel plate needs to be pushed by manpower to make it rest against the limit plate to maintain the horizontality. However, the overall operation is very dangerous. If the hand slips, the pressure plate can easily crush the hand. The overall efficiency of the equipment is low and the risk is high. Summary of the invention

The fixed wheel 24 is movably installed on the outer wall of the limit rod 23. When the stainless steel material is clamped between the two clamping blocks 21, the fixed wheel 24 will play a role of auxiliary fixing and guiding, ensuring that the material can maintain a stable position and state during the bending process, and conveniently move left and right when the stainless steel is taken out.

[0034] See also Figure 1 , Figure 4 A lifting assembly 3 is arranged on both sides above the workbench 1. The lifting assembly 3 includes a slide rail 31.

[0040] Embodiment 2 of the present utility model

[0041] See also Figure 1-3 A steel plate bending mechanism comprises a workbench 1, two slide grooves 11 are opened on both sides of the workbench 1, a clamping assembly 2 is arranged inside the slide groove 11, the clamping assembly 2 comprises a clamping block 21, two clamping blocks 21 are relatively arranged above the workbench 1, one side of the clamping block 21 is fixedly installed above the workbench 1, and two sliders 22 are fixedly installed on both sides below the clamping block 21 on the other side, and the sliders 22 are movably installed inside the slide groove 11, and a fixed plate 25 is arranged on the outer wall of the clamping block 21, and sliding rods 26 are movably installed inside the two sides of the fixed plate 25, and a pull plate 27 is fixedly connected above the sliding rods 26 on both sides, and abutment plates 28 are arranged below the sliding rods 26 on both sides, and a tension spring 29 is sleeved on the outer wall of the sliding rod 26, and the tension spring 29 is arranged between the abutment plate 28 and the fixed plate 25.

[0042] The clamping assembly 2 is the core part of the stainless steel bending device, which is responsible for firmly clamping the stainless steel material to be bent. It consists of two clamping blocks 21, which are relatively arranged above the workbench, one side of the clamping block 21 is fixedly installed on the workbench 1, and the other side of the clamping block 21 is moved horizontally by the cooperation of the slider 22 and the slide groove 11. This design allows the clamping assembly 2 to flexibly adapt to materials of different lengths. The fixed plate 25, the slide bar 26, the pull plate 27, the back plate 28 and the tension spring 29 together constitute an efficient clamping adjustment mechanism. The fixed plate is installed on the outer wall of the clamping block 21 to provide a stable support for the slide bar. The slide bar 26 is connected to the back plate 28 through the tension spring 29 to form an adjustable clamping structure. By operating the pull plate, the position of the slide bar and the back plate can be easily adjusted to adapt to stainless steel materials of different thicknesses or hardness. The function of the tension spring is to provide a constant clamping force for the clamping mechanism to ensure that the stainless steel material remains stable during the bending process.

[0043] See also Figure 7 A protrusion is provided below the clamping surface of the clamp block 21, and an anti-slip pad is provided on the outer wall of the protrusion of the clamp block 21 for clamping the stainless steel plate.

[0044] The protrusion below the clamping surface of the clamping block 21 not only increases the contact area between the clamping block 21 and the stainless steel plate, but also can be clamped by the protrusion when the stainless steel plate with different shapes of the fixed wheel 24 cannot stably clamp it, making the clamping more firm. At the same time, it can also prevent the stainless steel plate from sliding or shifting during the bending process to a certain extent. This design is particularly suitable for thinner or smoother stainless steel plates, ensuring the smooth progress of the bending process. The anti-skid pad set on the outer wall of the protrusion further enhances the stability of the clamping. The anti-skid pad is usually made of materials with excellent anti-skid properties, such as rubber or special plastics. These materials have sufficient friction coefficients and can effectively prevent the stainless steel plate from sliding during the clamping process. At the same time, the anti-skid pad also has certain elasticity and wear resistance, can be used for a long time without being easily damaged. Through the combination of the protrusion and the fixed wheel 24, the clamping block 21 can achieve stable clamping of stainless steel plates with different thicknesses and different surface characteristics. This design not only improves the accuracy and efficiency of bending, but also reduces the difficulty of operation, making the entire bending process smoother and more reliable.

[0045] The complete use steps and working principles of the above-mentioned embodiments 1 to 2 are as follows:

[0046] First, adjust the clamping blocks 21 on both sides of the workbench according to the thickness of the stainless steel plate, and pull the pull plate 27 to drive the sliding bars 26 on both sides to be pulled upward, so that the push plate 28 under the sliding bar 26 leaves the surface of the workbench 1, and the tension spring 29 is squeezed during the upward lifting of the push plate 28. When the push plate 28 is separated from the workbench 1, pull the pull plate 27 to make the clamping block 21 on one side move inside the slide groove 11 through the slider 22. When the clamping block 21 is pulled open, the stainless steel plate to be bent is placed vertically between the two clamping plates 21. The staff then pulls back one side of the clamping plate to make the fixed wheels 24 on both sides fit tightly against the stainless steel plate to clamp and fix it. Then, send open the pull plate 27, and the support force of the tension spring 29 makes the push plate 28 fit tightly against the surface of the workbench 1. The push plate 28 fixes the clamping plate through the downward force to prevent movement during the bending of the stainless steel plate.

[0047] Secondly, after the stainless steel plate is fixed, the lifting assembly 3 is started. At this time, the motor drives the screw rod 32 to rotate. When the screw rod 32 rotates, the slide plate 33 installed on its outer wall will move up and down along the slide rail 31. When the slide plate 33 moves to the bending position marked above, the motor stops working. At this time, the staff drives the rotating shaft 55 to rotate by turning the handle 56. When the rotating shaft 55 rotates, the transmission connection of the chain 54 drives the sprocket wheels 53 on both sides to rotate at the same time. The sprocket wheels 53 on both sides drive the adjusting screw rod 52 to rotate, thereby adjusting the distance of the right-angle groove 58, so that the groove in the middle of the right-angle groove 58 fits the outer wall of the marked position of the stainless steel plate. After the fitting is completed, the cylinder 41 drives the pressing plate 43 to apply pressure to the marked position of the stainless steel plate. The stainless steel plate is bent in the groove by pressure. The cylinder 41 switch is controlled according to the required angle to adjust the pressure degree of the pressing plate 43 on the stainless steel plate in turn.

[0048] After the stainless steel plate is bent once to form an L shape, if it needs to be bent again, it only needs to pull the pull plate 27 again, adjust the position of the clamping block 21 on one side, and clamp the horizontal surface of the L shape of the stainless steel plate through the protrusion set at the bottom of the clamping block, while the vertical surface of the L shape of the stainless steel plate can be clamped and supported by the fixed wheel 24 in the clamping block 21 fixed on the other side, so as to facilitate its bending again.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
