Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and more specifically, to a stainless steel production bending equipment. Background Technology

[0002] Bending is a common process in the production of stainless steel products, which involves bending flat stainless steel sheets into specific angles to meet subsequent assembly or usage requirements.

[0003] However, existing bending equipment has the following problems when in use: In the process of bending stainless steel sheets, much of the work is done manually. Operators must manually place the sheet into the equipment and then manually press the bending mechanism to achieve the bend. This method not only makes it difficult to accurately control the bending angle, resulting in poor consistency of the finished product, but also consumes a lot of manpower. More importantly, manual pressing is prone to operational errors, causing personnel to be injured by the equipment, and safety needs to be improved.

[0004] This invention enables stable conveying and precise bending of stainless steel sheets. Through multi-structure collaboration, the bending angle can be flexibly adjusted to ensure processing accuracy and efficiency, simplify operation and reduce maintenance costs, making it suitable for mass production needs. Summary of the Invention

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a stainless steel production bending equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel production bending equipment, comprising: a workbench, a motor bracket fixedly installed on one side of the bottom of the workbench, a protective box fixedly connected to the rear side of the upper end of the workbench, auxiliary wheels rotatably connected to both the left and right sides of the upper end of the workbench, a movable block slidably connected inside the protective box, the movable block slidably connected to the surface of the workbench, a rotating wheel rotatably connected to the front end of the movable block, a handle provided on the rear side of the movable block, a threaded post fixedly installed at the front end of the handle, the threaded post passing through the rear end of the protective box and threadedly connected to the interior of the movable block, the handle being in the shape of a disc valve and located at the rear end of the protective box, the auxiliary wheel and the rotating wheel forming an isosceles triangle, and rubber blocks being provided on the output surfaces of both.

[0007] A further preferred embodiment: support legs are fixedly installed at the four corners of the bottom of the workbench, a connecting plate is fixedly installed between the front and rear support legs, and a motor bracket is fixedly installed on the inner side of the connecting plate.

[0009] A further preferred embodiment: a gear is fixedly connected to the bottom of the connecting rod, and a chain meshes between the two gears.

[0010] A further preferred embodiment: the front end of the moving block is U-shaped, and a rotating rod is fixedly installed in the middle, the rotating rod being rotatably connected to the rotating wheel.

[0011] A further preferred embodiment: sliders are fixedly installed at both the upper and lower ends of the movable block, and the sliders are slidably connected to the workbench and the top of the protective box, respectively.

[0012] A further preferred embodiment: the front end of the handle is threadedly connected to a connecting sleeve, and the connecting sleeve is fixedly installed at the rear end of the protective box.

[0013] A further preferred embodiment: the connecting sleeve is internally threaded to a threaded post. Beneficial effects

[0014] 1. By incorporating gears and chains, synchronous transmission between the auxiliary wheels on both sides can be achieved, ensuring that their speeds are completely identical. This avoids speed differences caused by unilateral drive, thus ensuring uniform force on the stainless steel sheet during conveying, effectively preventing deviation or skewing, and improving conveying stability. This transmission structure can precisely distribute the power of a single motor to the two auxiliary wheels without the need for an additional power source, simplifying the overall structure of the equipment and reducing energy consumption and maintenance costs. At the same time, the meshing transmission of gears and chains has high transmission efficiency and stability, maintaining precise power transmission over a long period of time, reducing bending angle deviations caused by transmission errors, ensuring processing accuracy, and extending the service life of the equipment. It is suitable for continuous and efficient stainless steel bending production needs. 2. Equipped with a handle, threaded post, and movable block, the position of the rotating wheel can be easily adjusted to change the bending angle. The operator can rotate the disc valve-shaped handle to drive the movable block to slide back and forth through the threaded post, achieving precise adjustment of the vertical distance between the rotating wheel and the auxiliary wheel to meet different bending requirements. The operation is simple and flexible. The threaded connection has a self-locking characteristic, and with the connecting sleeve, the movable block can be stably held in the adjusted position to avoid displacement due to force during bending, thus ensuring processing accuracy. This structure does not require a complex power unit, and parameter adjustment can be completed by manual operation, simplifying the equipment control method and reducing the operating threshold and maintenance costs. 3. By incorporating sliders, bidirectional guiding support is provided for the sliding of the moving block. The sliders form stable sliding engagements with the worktable and the top of the protective box, effectively limiting the vertical sway of the moving block and ensuring that it moves precisely only in the front-back direction. This avoids tilting or offset caused by uneven force, ensuring that the rotary wheel and auxiliary wheel always maintain a symmetrical isosceles triangle layout, providing a reliable guarantee for the accuracy of the bending angle. At the same time, the sliders reduce the frictional resistance when the moving block slides, making position adjustment smoother and less labor-intensive, reducing component wear, extending the service life of the equipment, and further improving the overall structural stability and processing accuracy. 4. In summary, this stainless steel bending equipment, through its structure including auxiliary wheels, gears, chains, moving blocks, handles, threaded columns, rotating wheels, and sliders, achieves efficient and stable bending processing. The cooperation of gears and chains ensures synchronous transmission of the auxiliary wheels on both sides, preventing deviation during sheet material conveying and ensuring conveying stability. The combination of handles, threaded columns, and moving blocks allows for flexible adjustment of the rotating wheel position. By changing the isosceles triangle layout, the bending angle can be precisely controlled to meet diverse processing needs, and the self-locking characteristic of the threads ensures positional stability. The slider provides bidirectional guidance for the moving block, preventing it from tilting or wobbling, maintaining the symmetrical layout of the rotating wheels and auxiliary wheels, and improving bending accuracy. The synergistic effect of these structures simplifies the operation process, reduces maintenance costs, and balances processing efficiency and accuracy, making it suitable for the mass production needs of stainless steel sheets.

[0019] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0020] Please see Figure 1-3In this embodiment of the present invention, a stainless steel production bending equipment includes: a workbench 1, a motor bracket 2 fixedly installed on one side of the bottom of the workbench 1, a protective box 3 fixedly connected to the rear side of the upper end of the workbench 1, auxiliary wheels 202 rotatably connected to both the left and right sides of the upper end of the workbench 1, a movable block 301 slidably connected inside the protective box 3, the movable block 301 slidably connected to the surface of the workbench 1, a rotating wheel 305 rotatably connected to the front end of the movable block 301, a handle 302 provided on the rear side of the movable block 301, a threaded post 303 fixedly installed at the front end of the handle 302, the threaded post 303 passing through the rear end of the protective box 3 and threadedly connected to the interior of the movable block 301. The handle 302 is shaped like a disc valve and is located at the rear end of the protective box 3. The auxiliary wheel 202 and the rotating wheel 305 form an isosceles triangle, and rubber blocks are provided on the output surfaces. Support legs 101 are fixedly installed at the four corners of the bottom of the workbench 1. A connecting plate 102 is fixedly installed between the front and rear support legs 101. A motor bracket 2 is fixedly installed on the inner side of the connecting plate 102. A motor 201 is fixedly installed at the bottom of the motor bracket 2. A connecting rod 203 is fixedly connected to the middle of the auxiliary wheel 202. The bottom of the connecting rod 203 passes through the workbench 1 and is fixedly connected to the output end of the motor 201. The front end of the moving block 301 is U-shaped, and a rubber block is fixedly installed in the middle. Rotating rod 304 is rotatably connected to rotating wheel 305. A connecting sleeve 307 is threadedly connected to the front end of handle 302. The connecting sleeve 307 is fixedly installed at the rear end of protective box 3. The interior of the connecting sleeve 307 is threadedly connected to threaded post 303. The stainless steel sheet to be bent is placed on the surface of workbench 1, with the edges of the sheet adhering to the surfaces of the auxiliary wheels 202 on both sides. Since the auxiliary wheels 202 and rotating wheel 305 form an isosceles triangle, with auxiliary wheel 202 as the base line and the space between auxiliary wheel 202 and rotating wheel 305 as the waistline, the sheet will naturally lie between auxiliary wheel 202 and rotating wheel 305, aligned with the bending point below rotating wheel 305. In the area, the operator rotates the disc valve-shaped handle 302 at the rear of the protective box 3: the handle 302 drives the threaded column 303 at the front to rotate. Since the threaded column 303 is internally threadedly connected to the moving block 301, and the moving block 301 slides inside the protective box 3 and is in contact with the surface of the workbench 1, the rotation of the threaded column 303 will be converted into the back-and-forth sliding of the moving block 301. The U-shaped structure at the front of the moving block 301 drives the rotating rod 304 and the rotating wheel 305 to move synchronously, thereby changing the vertical distance between the rotating wheel 305 and the auxiliary wheel 202. Since the three are in an isosceles triangle, the change in distance directly affects the bending angle: the smaller the distance, the larger the bending angle.The greater the distance, the smaller the bending angle. After adjustment, the threaded column 303 is stabilized by the connecting sleeve 307 to prevent the moving block 301 from shifting during bending. The motor 201 drives the auxiliary wheel 202 to rotate continuously, which in turn drives the stainless steel sheet forward through friction. After being supported by the auxiliary wheel 202, the sheet moves to below the rotating wheel 305. Then, the position of the rotating wheel 305 is adjusted to form a triangular pressure point with the two auxiliary wheels 202. As the sheet moves forward, it is squeezed downward by the rotating wheel 305 and simultaneously subjected to pressure from the auxiliary wheels 202 on both sides. The upward supporting force causes bending deformation along the arc surface of the rotating wheel 305. The U-shaped structure of the moving block 301 provides stable support for the rotating wheel 305, ensuring uniform pressure during bending and preventing sheet metal displacement or uneven creases. After the stainless steel sheet completely passes through the bending area of ​​the auxiliary wheel 202 and the rotating wheel 305, the required angle is formed. The operator can then remove the processed part from the front end of the worktable 1. If the bending angle needs to be changed, the adjustment steps are repeated. If the machine needs to be stopped, the motor 201 is turned off, and if necessary, the handle 302 is turned in the reverse direction to reset the rotating wheel 305 to its initial position.

[0021] In this embodiment of the utility model, a gear 204 is fixedly connected to the bottom of the connecting rod 203, and a chain 205 meshes between the two gears 204. After the motor 201 is started, the output end of the motor drives the active connecting rod 203 to rotate. The active connecting rod 203 is one that is directly connected to the motor 201, which in turn drives the active gear 204 at its bottom to rotate synchronously. The active gear 204 drives the driven gear 204 at the bottom of the other connecting rod 203 to rotate synchronously through the meshing transmission of the chain 205. Finally, the two connecting rods 203 and the auxiliary wheel 202 at the top rotate in the same direction and at the same speed. The rotation speeds of the active gear and the driven gear are exactly the same.

[0022] In this embodiment of the utility model, sliders 306 are fixedly installed at both the upper and lower ends of the movable block 301. The sliders 306 are slidably connected to the top of the workbench 1 and the protective box 3, respectively. The sliders 306 at both ends of the movable block 301 form a sliding fit with the surface of the workbench 1 and the top of the protective box 3, respectively, forming a bidirectional guiding structure. When the threaded column 303 pushes or pulls the movable block 301, the sliders 306 slide smoothly along the corresponding slide rails or smooth contact surfaces of the workbench 1 and the protective box 3, limiting the swaying of the movable block 301 in the vertical direction and ensuring that it moves accurately only in the front-back direction. This bidirectional guiding design avoids the tilting or offset of the movable block 301 caused by uneven force, and keeps the isosceles triangle layout of the rotating wheel 305 and the auxiliary wheel 202 symmetrical, providing a basis for the accuracy of the bending angle.

[0023] Working principle: The stainless steel sheet is placed flat on the surface of the workbench 1, with its left and right edges adhering to the rubber blocks of the auxiliary wheels 202 on both sides. Since the auxiliary wheels 202 and the rotating wheel 305 form an isosceles triangle, with the auxiliary wheels as the base and the lines connecting the rotating wheel and the two auxiliary wheels as the two sides, the sheet naturally lies within the triangular area, with its front end aligned with the bend below the rotating wheel 305, ready for transport. At this time, the two auxiliary wheels 202 rotate synchronously under the drive of the motor. The motor output drives the active connecting rod 203 to rotate. The active connecting rod is directly connected to the motor, and its bottom active gear 204 rotates synchronously; via chain 2... The meshing transmission of 05, the driving gear 204 drives the driven gear 204 at the bottom of the other connecting rod 203 to rotate synchronously, ultimately realizing that the two connecting rods 203 and the top auxiliary wheel 202 rotate in the same direction and at the same speed. The friction between the surface rubber block and the plate drives the plate forward smoothly. Because the two auxiliary wheels rotate at the same speed, the plate is prevented from tilting. After being supported by the auxiliary wheel 202, the plate gradually enters the bending area below the rotating wheel 305. Then the operator turns the disc valve-shaped handle 302 at the rear of the protective box 3: the handle 302 drives the threaded post 303 at the front to rotate. Because the threaded post 303 and the inside of the moving block 301 are connected, the plate rotates smoothly forward. The threaded connection is used, and the moving block 301 forms a bidirectional guide with the worktable 1 and the protective box 3 through the upper and lower sliders 306. The rotation of the threaded column 303 is converted into the smooth back-and-forth sliding of the moving block 301. The U-shaped structure at the front end of the moving block 301 drives the rotating wheel 305 to move synchronously through the rotating rod 304, changing the vertical distance between the rotating wheel 305 and the auxiliary wheel 202: the smaller the distance, the lower the height of the isosceles triangle and the larger the bending angle of the plate; the larger the distance, the higher the height of the isosceles triangle and the smaller the bending angle of the plate. After adjusting to the target angle, the threaded column 303 is locked in a locked state through the threaded connection with the connecting sleeve 307. To prevent the moving block 301 from shifting due to force during bending, and to ensure the stability of the triangular layout of the rotating wheel 305 and the auxiliary wheel 202, when the sheet material moves under the rotating wheel 305, it is subjected to three forces: the downward pressure of the rotating wheel 305; the upward support force of the auxiliary wheels 202 on both sides; under the combined action of the three forces, the sheet material bends and deforms along the arc surface of the rotating wheel 305. Because the isosceles triangular layout of the rotating wheel and the auxiliary wheel is symmetrical, the force at the bending point is uniform, and the crease is flat. After the sheet material has completely passed through the bending area, it forms the required angle and is output from the front end of the workbench 1. The operator can then take away the processed stainless steel part.
