Description

Technical Field

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

[0002] A search revealed that application number 202323125430.X discloses a stainless steel elbow bending device, which includes a bending machine body and two sets of positioning rollers fixedly installed on the top of the bending machine body. A fixed frame is provided on the upper surface of the bending machine body away from the positioning rollers. An electric screw is longitudinally arranged on the fixed frame. The electric screw is driven to a movable plate located inside the fixed frame. A movable frame is fixedly connected to the top of the movable plate and movably connected to the fixed frame. A hand crank screw is rotatably connected to the movable frame laterally.

[0003] The stainless steel elbow bending device in this patent application uses a laterally movable pressure roller in conjunction with a positioning roller for bending. The position of the pressure roller can be adjusted to the right as needed to replace the positioning roller on the inner side of the bending surface with one of larger radii, thus enabling the bending of stainless steel elbows with different radii. However, in this process, because the top of the pressure roller is in a free state and lacks a support structure, it will be subjected to a reaction force when the pressure roller moves laterally for bending, which will put a large load on the connecting structure at the bottom of the pressure roller and easily cause the entire pressure roller to deform, reducing the service life of the equipment. Therefore, we propose a new type of stainless steel elbow bending device. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a new type of stainless steel elbow bending device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel stainless steel elbow bending device, comprising a bending machine body and two sets of positioning rollers disposed on the top of the bending machine body. A laterally movable pressure roller is disposed at the front end of the bending machine body. A C-shaped movable support is slidably connected to the front end of the bending machine body. An adjusting groove is provided on the front center side of the top wall of the bending machine body. An adjusting mechanism for driving the movable support to move back and forth is disposed inside the adjusting groove. The adjusting mechanism includes an adjusting nut block that is slidably connected inside the adjusting groove and is adjustable back and forth. The top of the adjusting nut block is fixedly installed at the center of the bottom wall of the movable support. Lateral grooves are symmetrically disposed on the upper and lower side walls of the inner cavity of the movable support. A driving component for driving the pressure roller to move laterally is disposed inside the lower lateral groove. The driving component includes an electric screw disposed inside the lower lateral groove and a movable disc connected to the electric screw. The pressure roller is disposed on the top of the movable disc, and a lateral slider is disposed on the top of the pressure roller and slidably connected to the upper lateral groove.

[0006] Furthermore, the adjusting nut block is internally threaded with an adjusting threaded rod that is rotatably connected to the inside of the adjusting groove.

[0007] Furthermore, an adjustment motor is fixedly installed on the upper side of the front wall of the bending machine body.

[0008] Furthermore, the front end of the adjusting threaded rod passes through the front wall of the adjusting slide groove and is fixedly installed with the output end of the adjusting motor.

[0009] Furthermore, symmetrical limit grooves are provided on the front side of the top wall of the bending machine body.

[0010] Furthermore, two limiting sliders that are fixedly connected to the bottom wall of the movable bracket are slidably connected inside the two limiting grooves.

[0011] Furthermore, the cross-sections of the inner cavities of the two limiting grooves and the cross-sections of the two limiting sliders are both T-shaped and compatible.

[0012] Furthermore, the front side of the top wall of the bending machine body is evenly marked with distance scales.

[0013] Furthermore, the transverse slider is slidably connected to a transverse slide rod that is fixedly connected to the transverse slide groove located above.

[0014] This utility model provides a novel stainless steel elbow bending device. It has the following beneficial effects:

[0015] 1. This novel stainless steel elbow bending device, through the setting of an adjustment mechanism and a transverse slider, allows the stainless steel pipe to be processed to be placed between positioning rollers and locked in place. Based on the radius of the stainless steel pipe, the output of the adjusting motor drives the adjusting threaded rod to rotate, forcing the adjusting nut block threaded to the adjusting threaded rod to move the movable bracket and the pressure roller on it back and forth to adjust the position, changing the distance between the positioning roller and the moving bracket. This facilitates the replacement of the positioning roller to produce stainless steel elbows of different radii. Then, the electric screw drives the movable disc to move to the right along the transverse groove below. The movable disc drives the pressure roller to move to the right, applying pressure to the right side of the stainless steel straight pipe for bending. The transverse slider, through its sliding connection with the transverse slide block, provides a limiting and guiding effect to the top of the pressure roller, improving the stability of the pressure roller installation. The operation is simple and practical, with a reasonable and compact structure, improving the stability of the pressure roller installation structure, reducing damage to the pressure roller during processing, and extending the service life of the equipment.

[0016] 2. This new type of stainless steel elbow bending device, by setting limit sliders, enhances the connection between the moving support and the bending machine body by sliding the two limit sliders with the inside of the two limit grooves, thereby improving the stability of the equipment structure.

[0017] 3. This new type of stainless steel elbow bending device, by setting a distance scale, allows for precise adjustment of the position of the pressure roller by using the front end of the moving bracket in conjunction with the distance scale, since the distance between the moving bracket and the pressure roller relative to the positioning roller is fixed, thus improving the ease of use of the equipment.

A laterally movable pressure roller 23 is disposed at the front end of the bending machine body 10. A C-shaped movable support 12 is slidably connected to the front end of the bending machine body 10. An adjusting groove 13 is provided on the front center side of the top wall of the bending machine body 10. An adjusting mechanism for moving the movable support 12 back and forth is disposed inside the adjusting groove 13. The adjusting mechanism includes an adjusting nut block 15 that is slidably connected inside the adjusting groove 13 and adjustable back and forth. The top end of the adjusting nut block 15 is fixedly installed at the center of the bottom wall of the movable support 12. An adjusting threaded rod 14 that is rotatably connected to the adjusting groove 13 is threaded inside the adjusting nut block 15. An adjusting motor 16 is fixedly installed on the upper side of the front wall of the bending machine body 10. The front end of the adjusting threaded rod 14 passes through the front wall of the adjusting groove 13 and is fixedly installed with the output end of the adjusting motor 16. Limiting devices are symmetrically provided on the front side of the top wall of the bending machine body 10. The sliding groove 17 has two limiting sliding grooves 17 with two limiting sliders 18 that are fixedly connected to the bottom wall of the moving bracket 12. The cross-section of the inner cavity of the two limiting sliding grooves 17 and the cross-section of the two limiting sliders 18 are both T-shaped and matched. The front side of the top wall of the bending machine body 10 is evenly provided with distance scales 19. The upper and lower side walls of the inner cavity of the moving bracket 12 are symmetrically provided with transverse sliding grooves 20. The transverse sliding groove 20 located in the lower position is provided with a drive assembly for driving the pressure roller 23 to move laterally. The drive assembly includes an electric screw 21 located in the transverse sliding groove 20 located in the lower position and a movable disk 22 connected to the electric screw 21.

The transverse slider 24 is slidably connected with a transverse sliding rod 25 that is fixedly connected to the inner wall of the transverse sliding groove 20 located in the upper position.

[0026] The working principle of this utility model is as follows: In use, the stainless steel pipe to be processed is placed between the positioning rollers 11 and locked in place. Based on the radius of the stainless steel pipe, the output of the adjusting motor 16 is controlled to drive the adjusting threaded rod 14 to rotate. This forces the adjusting nut block 15, which is threadedly connected to the adjusting threaded rod 14, to move the movable bracket 12 and the pressure roller 23 on it back and forth to adjust its position, changing the distance between it and the positioning rollers 11. This facilitates the replacement of the positioning rollers 11 to produce stainless steel bends of different radii. Then, the electric screw 21 is controlled to drive the movable disc 22 to move to the right along the transverse slide groove 20 at the lower position. The movable disc 22 drives the pressure roller 23 to move to the right, applying pressure to the right side of the stainless steel straight pipe for bending processing. The transverse slide rod 25, through its interaction with the transverse slide... The sliding connection of block 24 provides a limiting and guiding effect on the top of the pressure roller 23, improving the stability of the pressure roller 23 installation. The above operation is simple and practical, with a reasonable and compact structure, which improves the stability of the installation structure of the pressure roller 23, reduces the damage to the pressure roller 23 during processing, and extends the service life of the equipment. The two limiting sliders 18 enhance the connection between the moving bracket 12 and the bending machine body 10 through the sliding connection with the two limiting slide grooves 17, improving the stability of the equipment structure. Since the distance between the moving bracket 12 and the pressure roller 23 relative to the positioning roller 11 is fixed, the position of the pressure roller 23 can be precisely adjusted by using the front end of the moving bracket 12 in conjunction with the distance scale 19, improving the ease of use of the equipment.
