Description

Technical Field

[0001] This utility model relates to the field of stainless steel cabinet production technology, and in particular to a bending device for stainless steel cabinet production. Background Technology

[0002] In the stainless steel cabinet manufacturing industry, with the development of the industry and the improvement of consumers' aesthetics, the requirements for the precision of cabinet appearance and structure are becoming more and more stringent. The bending process of stainless steel sheets, especially the four-sided bending process, is crucial in the forming of cabinet components. For example, for the production of stainless steel cabinet doors, 304 stainless steel cold-rolled sheets with a thickness of 1-2 mm are often used. Due to their good corrosion resistance and processing performance, they are widely used. When bending these sheets on four sides, high requirements are placed on the process and equipment.

[0003] Traditional bending equipment has many shortcomings when handling four-sided bending. When it is necessary to bend the sheet metal on four sides, it is often necessary to disassemble and reinstall the clamps multiple times, which is cumbersome, inefficient, and may introduce errors with each repositioning, further reducing product quality. Therefore, a bending device for stainless steel cabinet production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bending device for the production of stainless steel cabinets, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending device for stainless steel cabinet production includes a base plate, a fixed seat fixedly installed on the top side of the base plate, a groove opened on the top side of the fixed seat, a plurality of guide blocks slidably installed in the groove, a common placement plate fixedly connected to the top side of the plurality of guide blocks, a pressure plate provided above the placement plate, extension components provided on the outer sides of both the pressure plate and the placement plate, a rotating pressing component provided above the base plate, a forming block fixedly installed on the top side of the base plate, and a bending component provided above the forming block.

[0007] Preferably, the expansion component includes a set of first slots on both sides of the placement plate and the pressure plate, with two slots in each set. A first plug is inserted into each slot, and the same first expansion plate is fixedly connected to the other side of each first plug.

[0008] Preferably, a set of second slots is provided on both sides of the placement plate and the pressure plate, with two slots in each set. A second plug is inserted into each slot, and the same second expansion plate is fixedly connected to the other side of each plug.

[0009] Preferably, the rotary pressing assembly includes an electric push rod fixedly installed on the bottom side of the base plate, and the output end of the electric push rod passes through the base plate and is fixedly connected to the top plate.

[0010] Preferably, a motor is fixedly installed on the top side of the top plate, and the output end of the motor rotates through the top plate and is fixedly connected to the top side of the pressure plate.

[0011] Preferably, the bending assembly includes a bracket fixedly installed on one side of the base plate. The bracket is L-shaped, and a cylinder is fixedly installed on the top side of the bracket. The output end of the cylinder passes through the bracket and is fixedly connected to a bending head. One side of the bending head is at the same horizontal line as one side of the forming block.

[0012] Preferably, the bottom side of the base plate is fixedly equipped with four support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When it is necessary to bend the stainless steel sheet on all four sides, the pressure plate is pressed down by the electric push rod to firmly clamp the stainless steel sheet. After one side is bent, the motor is started. The motor drives the pressure plate to rotate. Due to the clamping of the plate and the pressure plate, the stainless steel sheet can be rotated smoothly. This process does not require loosening the clamps and directly realizes the rotation of the sheet, which greatly reduces the operation steps, improves work efficiency, and meets the needs of large-scale production for efficient operation.

[0015] 2. By incorporating guide blocks, forming blocks, and a cylinder and bending head within the bending assembly, precise bending is ensured. Multiple guide blocks slide within the grooves of the placement plate, providing guidance and assistance during the rotation of the stainless steel plate, ensuring smooth rotation. The bending head and forming block are aligned on one side. Activating the cylinder moves the bending head downwards, allowing for a precise 90-degree bend to the stainless steel plate. The entire process effectively reduces errors caused by human intervention and repositioning, ensuring consistent bending angle and position, resulting in stainless steel plates with regular edges and accurate dimensions, thus improving product quality.

Detailed Implementation

[0021] 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.

[0022] Reference Figure 1-4 A bending device for stainless steel cabinet production includes a base plate 1, a fixed seat 3 fixedly installed on the top side of the base plate 1, a groove 4 opened on the top side of the fixed seat 3, multiple guide blocks 5 slidably installed in the groove 4, a common placement plate 6 fixedly connected to the top side of the multiple guide blocks 5, a pressure plate 10 arranged above the placement plate 6, extension components arranged on the outer sides of both the pressure plate 10 and the placement plate 6, a rotating pressing component arranged above the base plate 1, a forming block 17 fixedly installed on the top side of the base plate 1, and a bending component arranged above the forming block 17. The pressure plate 10 is driven to rotate by a motor 9. When one side of the stainless steel plate is bent, the motor 9 is started, and the motor 9 rotates, driving the pressure plate 10 to rotate. Since the stainless steel plate is bent at this time... The plate remains pressed by the placement plate 6 and the pressure plate 10. The placement plate 6 and the pressure plate 10 will synchronously drive the stainless steel plate to rotate. During the rotation, multiple guide blocks 5 play a guiding and assisting role in the rotation, ensuring that the stainless steel plate rotates smoothly. When the other end of the stainless steel plate rotates to above the forming block 17, the cylinder 19 is activated again, and the bending head 20 moves accordingly to perform a second bend on the stainless steel plate. Then, the above operation is repeated to achieve four-sided bending of the stainless steel plate. This method of turning without releasing the clamps greatly reduces human intervention and repositioning errors, ensuring the high consistency of the bending angle and position each time, so that the processed stainless steel plate has regular four sides and accurate dimensions.

[0023] Specifically, the expansion assembly includes a set of two first slots 11 on each side of the placement plate 6 and the pressure plate 10. Each set of first slots 11 contains a first insert 13, and the other side of each first insert 13 is fixedly connected to the same first expansion plate 14. Similarly, a set of two second slots 12 are provided on the other sides of the placement plate 6 and the pressure plate 10. Each set of second slots 12 contains a second insert 15, and the other side of each second insert 15 is fixedly connected to the same second expansion plate 16. By providing the first expansion plate 14 and the second... When bending large stainless steel plates, the extension plate 16 expands the placement area by inserting the first extension plate 14 and the second extension plate 16 into the first slot 11 and the second slot 12, respectively. This expansion effectively prevents the plate from being pushed upwards due to uneven force when bending large stainless steel plates, ensuring the stability of the bending process and the accuracy of the bending effect. Furthermore, the corresponding extension plate can be easily replaced according to the size of the stainless steel plate. For slightly larger plates, a matching extension plate can be quickly installed to ensure a perfect fit of the placement area, allowing the bending operation to proceed smoothly.

[0024] Specifically, the rotary pressing assembly includes an electric push rod 7 fixedly installed on the bottom side of the base plate 1. The output end of the electric push rod 7 passes through the base plate 1 and is fixedly connected to the top plate 8. A motor 9 is fixedly installed on the top side of the top plate 8. The output end of the motor 9 rotates through the top plate 8 and is fixedly connected to the top side of the pressure plate 10. With the electric push rod 7 installed, when the stainless steel plate needs to be pressed, the electric push rod 7 is activated. The electric push rod 7 moves, causing the top plate 8 to move downward, thereby causing the pressure plate 10 below the top plate 8 to apply pressure to the stainless steel plate, pressing it firmly onto the placement plate 6. The stable clamping state avoids bending deviations caused by displacement or shaking of the stainless steel plate during subsequent bending processes, providing a reliable guarantee for high-precision bending processing, effectively reducing the defect rate, and ensuring the smooth progress of the entire bending process.

[0025] Specifically, the bending assembly includes a bracket 18 fixedly installed on one side of the base plate 1. The bracket 18 is L-shaped, and a cylinder 19 is fixedly installed on the top side of the bracket 18. The output end of the cylinder 19 passes through the bracket 18 and is fixedly connected to a bending head 20. One side of the bending head 20 is on the same horizontal line as one side of the forming block 17. Four support legs 2 are fixedly installed on the bottom side of the base plate 1. By setting up the cylinder 19, when bending is performed, the cylinder 19 is activated, and the operation of the cylinder 19 drives the bending head 20 to move downward. Since one side of the bending head 20 is on the same horizontal line as one side of the forming block 17, the stainless steel plate can be precisely bent at a 90-degree angle during the downward movement of the bending head 20. This precise positioning makes the angle error of each bend extremely small, effectively ensuring the shape accuracy of the stainless steel plate after bending and meeting the process requirements of high-precision bending for stainless steel cabinet components.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: First, place the stainless steel sheet to be bent on the placement plate 6, ensuring that the side to be bent extends beyond one side of the forming block 17. After proper placement, start the electric push rod 7. The electric push rod 7 moves, causing the top plate 8 to move downwards, which in turn causes the pressure plate 10 below the top plate 8 to apply pressure to the stainless steel sheet, firmly pressing it onto the placement plate 6. After pressing is complete, start the cylinder 19. The cylinder 19 moves, causing the bending head 20 to move downwards. Since one side of the bending head 20 is on the same horizontal line as one side of the forming block 17, the stainless steel sheet can be precisely bent at a 90-degree angle during the downward movement of the bending head 20. After one side of the stainless steel sheet is bent, start the motor 9. The motor 9 rotates, causing the pressure plate 10 to rotate. At this time, the stainless steel sheet is still being pressed by the placement plate 6 and the pressure plate 10. In this state, the placement plate 6 and the pressure plate 10 will synchronously drive the stainless steel plate to rotate. During the rotation, multiple guide blocks 5 play a guiding and assisting role in the rotation, ensuring that the stainless steel plate rotates smoothly. When the other end of the stainless steel plate rotates to above the forming block 17, the cylinder 19 is activated again, and the bending head 20 moves accordingly to perform a second bend on the stainless steel plate. By repeating the above operation, the four sides of the stainless steel plate can be bent. When bending larger stainless steel plates, by inserting the first extension plate 14 and the second extension plate 16 into the first slot 11 and the second slot 12 respectively, the placement area can be expanded. This expansion effectively avoids the situation where the plate is pushed upward due to uneven force when bending large stainless steel plates, ensuring the stability of the bending process and the accuracy of the bending effect.
