Description

Technical Field

[0001] This utility model relates to the field of pipe fittings production technology, specifically a bending device for pipe fittings production. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gas, liquid, or fluid containing solid particles. Typically, fluid is pressurized by blowers, compressors, pumps, boilers, etc., and then flows from the high-pressure area to the low-pressure area in the pipeline. It can also be transported by the fluid's own pressure or gravity. Some of the fittings on the pipeline need to be bent during use, so bending devices are used.

[0003] Patent CN220591214U discloses a pipe fitting bending device, including a workbench and pipe fittings. An L-shaped plate is mounted on the workbench, and a cylinder is mounted on the L-shaped plate. A pressure block is mounted on the output end of the cylinder. An arc-shaped groove is formed on the workbench, and the pipe fittings are placed on the workbench. A fixing device is mounted on the L-shaped plate, symmetrically distributed on both sides of the center line of the L-shaped plate. A horizontal plate is mounted on the L-shaped plate, and a vertical plate is mounted on the horizontal plate. When the upward-moving rod support moves upward within the groove on the vertical plate, it compresses a spring. Conversely, the elasticity of the spring causes the rod support to move downward, thus the rollers firmly and stably hold both ends of the pipe fittings against the workbench. When the cylinder operates, the pressure block pulls the pipe fittings into the arc-shaped groove, causing the rollers to rotate on the rod support via a pin, bending the pipe fittings. Both ends can move freely.

[0004] The pipe fitting bending equipment mentioned in the above patent has a fixed shape for the pressure block and the arc groove, which cannot adjust the bending angle of the pipe fitting. This is inconvenient when it is necessary to bend the pipe fitting at different angles. Therefore, we need to propose a bending device for pipe fitting production. Utility Model Content

[0024] By setting the positioning component, one end of the pipe fitting body 2 can be fixed to the top of the base 1. Specifically, the user can insert one end of the pipe fitting body 2 into the inner cavity of the positioning shell 3, and then tighten the positioning rod 6. The rotation of the positioning rod 6 will drive the clamping plate 4 to move towards the pipe fitting body 2, so that the clamping plate 4 clamps and fixes one end of the pipe fitting body 2 in the inner cavity of the positioning shell 3.

[0025] Preferably, a guide assembly for improving the stability of movement is provided between the clamping plate 4 and the positioning shell 3. The guide assembly includes two sets of guide rods 7 fixedly installed on one side of the clamping plate 4. A guide hole 8 is opened on the surface of the positioning shell 3 at the corresponding position of the guide rod 7. The surface of the guide rod 7 is slidably connected to the inner wall of the guide hole 8.

[0026] By setting the guide component, the stability of the movement of the clamping plate 4 can be improved. When the clamping plate 4 moves, it will drive the guide rod 7 to slide in the inner cavity of the guide hole 8.

[0028] By using the bending component and the support component together, the positioned pipe fitting body 2 can be bent. Specifically, the user can crank the handle 18. The rotation of the handle 18 will drive the drive screw 19 to rotate, which in turn drives the connecting rod 16 to move through the slide 20 and the connecting seat 21, which in turn drives the bending roller 15 to move, so that the bending roller 15 squeezes and bends the pipe fitting body 2. Under the support of the support roller 10 and the squeezing action of the bending roller 15, the pipe fitting body 2 can be successfully bent.

[0030] By setting the limiting component, the stability of the slide 20 can be improved. When the slide 20 moves, it will drive the T-shaped limiting block 22 to slide in the inner cavity of the limiting groove 23. Furthermore, the cooperation between the T-shaped limiting block 22 and the limiting groove 23 can also prevent the slide 20 from disengaging from the base 1.

The top of the locking nut 14 fits against the bottom of the base 1.

[0032] By setting the angle fixing component, the bending angle of the pipe fitting body 2 can be adjusted, so that the pipe fitting body 2 can be bent at different angles. Specifically, when adjusting, the user can select the bending angle and insert the threaded rod 13 at the bottom of the fixing rod 12 into the corresponding mounting hole 11, and then tighten the locking nut 14 at the bottom of the threaded rod 13 to install and fix the use position of the fixing rod 12.
