Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a bending mechanism for U-shaped plate production. Background Technology

[0002] An existing bending mechanism for processing U-shaped steel plates, with publication number CN 221064015 U, involves starting a motor to drive a threaded rod to rotate. When the threaded rod rotates, it causes the first U-shaped plate to slide within a groove on a guide rail, which in turn causes a movable roller on the shaft to approach a fixed roller. The movable roller and the two fixed rollers form three points that can be used for U-shaped processing of the steel plate. When the drive motor is started, the second gear meshes with the first gear to drive the shaft and the movable roller to rotate, causing the steel plate to roll and form on the surface of the fixed roller. However, the above mechanism is cumbersome to operate and has low efficiency during production, making it inconvenient for batch processing. Utility Model Content

[0003] The purpose of this invention is to provide a bending mechanism for U-shaped plate production in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A bending mechanism for producing U-shaped plates includes a machine body with a hydraulic column mounted on it, and a bending assembly mounted on the machine body. The bending assembly is equipped with a limiting component for adjusting and limiting the plate. The bending assembly includes a base plate mounted on the machine body, a guide column vertically fixed on the base plate, a guide sleeve sleeved on the upper side of the guide column, a top plate fixed on the upper end of the guide sleeve, a support platform fixed on the base plate, a recessed platform on the upper surface of the support platform, a die cavity disposed within the recessed platform, a sliding column disposed at the lower end of the die cavity, a spring sleeved on the sliding column located below the die cavity, support rollers disposed on both sides of the die cavity on the support platform, and a punch mounted at the lower end of the top plate corresponding to the die cavity.

[0006] Further details: The limiting assembly includes a lateral limiting component and a longitudinal limiting component. The longitudinal limiting component is mounted on the lateral limiting component, and the lateral limiting components are respectively mounted on both sides of the support platform. The upper surface of the support platform is provided with scale lines. The lateral limiting component includes an adjusting stud mounted on the front side of the support platform. A limiting frame is provided on the opposite end of the adjusting stud. Sliding grooves are provided on the front and rear side walls of the support platform. The longitudinal limiting component includes left and right spiral screws mounted on the limiting frame. Adjusting plates are arranged opposite each other on the left and right spiral screws.

[0010] Further configuration: The support roller is rotatably connected to the support platform, and the upper tangent surface of the support roller is flush with the upper surface of the support platform.

[0011] Further settings: The width of the punch is less than the width of the die, and the length of the support roller is greater than the width of the die.

The bending assembly is provided with a limiting component for adjusting and limiting the plate.

[0027] In this embodiment: the bending assembly includes a base plate 21 mounted on the machine body 11, a guide post 23 vertically fixed on the base plate 21, a guide sleeve 24 sleeved on the upper side of the guide post 23, a top plate 25 fixed on the upper end of the guide sleeve 24, a support platform 22 fixed on the base plate 21, a recessed platform provided on the upper end surface of the support platform 22, a die 27 provided in the recessed platform, a sliding post 28 provided at the lower end of the die 27, a spring 29 sleeved on the sliding post 28 located below the die 27, support rollers 210 provided on both sides of the die 27 on the support platform 22, and a punch 26 installed at the lower end of the top plate 25 corresponding to the position of the die 27. The die 27 is slidably connected to the support platform 22. There are two sliding columns 28, and the sliding columns 28 have flanges at the lower end of the support platform 22. The support roller 210 is rotatably connected to the support platform 22, and the upper tangent of the support roller 210 is flush with the upper end face of the support platform 22. The width of the punch 26 is smaller than the width of the die 27. The punch 26 retracts upward on both sides. The length of the support roller 210 is greater than the width of the die 27. The hydraulic column 12 extends and pushes the top plate 25 and the punch 26 to squeeze the steel plate under the guidance of the guide sleeve 24 and the guide column 23. The steel plate is pushed by the punch 26 to move towards the die 27. The support roller 210 supports the two sides of the steel plate until the steel plate is squeezed into a U-shaped structure. The hydraulic column 12 returns to its original position. The spring 29 pushes the die 27 upward under the guidance of the sliding column 28, which facilitates the forming and unloading of the U-shaped steel plate.

[0028] In this embodiment: the limiting component includes a lateral limiting member and a longitudinal limiting member. The longitudinal limiting member is disposed on the lateral limiting member. The lateral limiting members are respectively disposed on both sides of the support platform 22. The upper surface of the support platform 22 is provided with a scale line 35 to facilitate observation and confirmation of the lateral limiting adjustment position. The lateral limiting member includes an adjusting stud 34 disposed on the front side of the support platform 22. A limiting frame 31 is disposed on the opposite end of the adjusting stud 34. Slide grooves 221 are opened on the front and rear side walls of the support platform 22. The longitudinal limiting member includes left and right spiral screws 32 disposed on the limiting frame 31. Adjusting plates 33 are disposed opposite to each other on the left and right spiral screws 32. A through groove is opened on the limiting frame 31 through which the adjusting plates 33 pass. The left and right spiral screws 32 are rotatably connected to the limiting frame 31, and the left and right spiral screws 32 are threadedly connected to the adjusting plate 33. The adjusting plate 33 is slidably connected to the limiting frame 31. The adjusting stud 34 is threadedly connected to the support platform 22, and the adjusting stud 34 is rotatably connected to the limiting frame 31. The limiting frame 31 is slidably connected to the slide groove 221. By rotating the adjusting studs 34 on both sides, the limiting frame 31 is moved and adjusted towards the bending position under the limitation of the slide groove 221, limiting the transverse ends of the steel plate. Then, the left and right spiral screws 32 are rotated, causing the left and right spiral screws 32 to drive the adjusting plate 33 to move relative to the limiting frame 31, limiting the longitudinal direction of the steel plate. This facilitates the adjustment and limitation of steel plates with different lengths, widths, and asymmetrical bending positions.

[0029] The working principle and usage process of this utility model are as follows: According to the length, width and bending position of the steel plate, adjust the transverse and longitudinal limiting parts, and rotate the adjusting studs 34 on both sides respectively, so that the limiting frame 31 moves and adjusts towards the bending position under the limiting of the slide groove 221, limiting the transverse ends of the steel plate. Then, rotate the left and right spiral screws 32, so that the left and right spiral screws 32 drive the adjusting plate 33 to move relative to each other on the limiting frame 31, limiting the longitudinal direction of the steel plate. Place the steel plate on the support platform 22, and push the top plate 25 and the punch 26 under the guidance of the guide sleeve 24 and the guide post 23 to squeeze the steel plate, so that the steel plate moves towards the die 27 after being pushed by the punch 26. The support roller 210 supports both sides of the steel plate until the steel plate is squeezed into a U-shaped structure. The hydraulic column 12 returns to its original position, and the spring 29 pushes the die 27 upward under the guidance of the slide post 28.
