Description

Technical Field

[0001] This utility model relates to the field of headrest tube processing technology, and in particular to an automotive headrest tube bending machine. Background Technology

[0002] Hollow tube headrests are important components of car seat frames. They are made by bending steel tubes, which are then placed on a tube bending machine and bent into shape.

[0003] Existing pipe bending machines bend pipes by inserting them into the machine and moving bending blocks. During production and transportation, pipes may be subjected to external forces, causing slight bending or deformation. This makes them difficult to place on the bending machine for fixing and bending. Furthermore, slight bending deformation affects the subsequent bending accuracy and product quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose an automotive headrest tube bending machine to solve the problem that the bending deformation of the tube itself affects the bending quality.

[0005] To achieve the above objectives, this utility model provides a car headrest tube bending machine, including a worktable. A slide rail is provided at one end of the worktable, and a movable seat is slidably mounted on the slide rail. A clamping and rotating mechanism is provided on the movable seat, which clamps one end of the tube and drives it to rotate. A column is installed at the other end of the worktable, and a bending seat is installed on the upper end of the column. A placement groove is provided inside the bending seat, and a bending mechanism is fitted onto the outside of the column. The tube is placed onto the bending seat through the placement groove, and the bending mechanism bends the tube. A straightening mechanism is provided on the bending seat, which corrects the tube during placement.

[0006] A further improvement is that the bending mechanism includes a rotating sleeve, which is sleeved on the outside of the column. The rotating sleeve is driven to rotate by a motor. A rotating ring is sleeved on the rotating sleeve, and a bending block is fixedly connected to the rotating ring.

[0007] A further improvement is that a guide block is connected to the outer side of the rotating sleeve, and a guide groove is opened on the inner side of the rotating ring, with the guide block and the guide groove being adapted to each other.

[0008] A further improvement is that a lifting ring is fitted on the rotating sleeve, the lifting ring is rotatably connected to the lower side of the rotating ring, and the lifting ring is driven to rise and fall by a lifting cylinder, which in turn drives the rotating ring to rise and fall.

[0009] A further improvement is that the straightening mechanism includes two sets of transverse straightening wheels and two sets of longitudinal straightening wheels. A transverse support and a longitudinal support are installed at the end of the bending seat away from the bending mechanism. The transverse support is set on the left and right sides of the placement groove, and the longitudinal support is set on the upper and lower sides of the placement groove. The two sets of transverse straightening wheels are symmetrically installed on the transverse support, and the two sets of longitudinal straightening wheels are symmetrically installed on the longitudinal support.

[0010] A further improvement is that bending grooves are provided on both sides of the bending seat near the bending mechanism.

[0011] The beneficial effects of this utility model are as follows: One end of the pipe is placed on the bending seat, and the other end is clamped and fixed by the clamping and rotating mechanism. The rotating ring drives the bending block to bend the pipe. The clamping and rotating mechanism pushes the pipe along with the moving seat, allowing the bending mechanism to bend the pipe multiple times at different positions to meet various processing needs. A straightening mechanism is also included. During the insertion of the pipe into the placement slot of the bending seat, the transverse and longitudinal straightening wheels straighten the pipe in multiple directions. The clamping and rotating mechanism pushes the pipe back, and the pipe is straightened a second time by the transverse and longitudinal straightening wheels, ensuring the straightness of the pipe and reducing the impact of slight bending deformation on the bend, thus greatly improving product quality.

[0021] like Figure 1-4 As shown, this embodiment provides an automotive headrest tube bending machine, including a worktable 1, a slide rail 2 at one end of the worktable 1, a movable seat 3 slidably mounted on the slide rail 2, the movable seat 3 being driven to slide on the slide rail 2 by a push cylinder, and a clamping and rotating mechanism 4 mounted on the movable seat 3, which clamps one end of the tube and drives the tube to rotate. The clamping and rotating mechanism 4 includes a rotating shaft and a cylinder, the rotating shaft being driven to rotate by a servo motor, a gripper mounted on the rotating shaft, and a sleeve sleeved on the outside of the rotating shaft, the output end of the cylinder being connected to the sleeve via a connecting rod, the cylinder pushing the sleeve to move outside the rotating shaft via the connecting rod, the movement of the sleeve driving the gripper to clamp and fix it. The clamping and rotating mechanism 4 is prior art and is not particularly limited here.

[0022] A column 5 is installed at the other end of the workbench 1. A bending seat 6 is installed on the upper end of the column 5. A placement groove 7 is opened in the bending seat 6. A bending mechanism is sleeved on the outside of the column 5. Bending grooves are opened on both sides of the bending seat 6 near the bending mechanism. The pipe is placed on the bending seat 6 through the placement groove 7. The bending mechanism pushes the pipe along the bending groove to bend it. The bending mechanism includes a rotating sleeve 8, which is sleeved on the outside of the column 5. The rotating sleeve 8 is driven to rotate by a motor. A rotating ring 9 is sleeved on the rotating sleeve 8. A bending block 10 is fixedly connected to the rotating ring 9. A guide groove 12 is opened on the inner side of the rotating ring 9. A guide block 11 is adapted to the guide groove 12. The rotating sleeve 8 drives the rotating ring 9 to rotate through the guide block 11. The bending block 10 is fixedly connected to the rotating ring 9. The rotating ring 9 drives the bending block 10 to rotate. The bending block 10 fits against one side of the pipe and bends the pipe. A lifting ring 13 is fitted on the rotating sleeve 8. The lifting ring 13 is rotatably connected to the lower side of the rotating ring 9. The lifting ring 13 is driven to lift and lower by a lifting cylinder, and the lifting ring 13 drives the rotating ring 9 to lift and lower.

[0023] like Figure 3 , 4 As shown, a straightening mechanism is provided on the bending seat 6, which corrects the pipe during placement. The straightening mechanism includes two sets of transverse straightening wheels 14 and two sets of longitudinal straightening wheels 15. A transverse support 16 and a longitudinal support 17 are installed at the end of the bending seat 6 away from the bending mechanism. The transverse support 16 is positioned on the left and right sides of the placement groove 7, and the longitudinal support 17 is positioned on the upper and lower sides of the placement groove 7. The two sets of transverse straightening wheels 14 are symmetrically mounted on the transverse support 16, and the two sets of longitudinal straightening wheels 15 are symmetrically mounted on the longitudinal support 17. During the process of the pipe being inserted into the placement groove 7 and moving towards the clamping and rotating mechanism 4, the pipe passes sequentially through the transverse straightening wheels 14 and the longitudinal straightening wheels 15, which straighten the pipe and reduce bending deformation. Both the transverse support 16 and the longitudinal support 17 are equipped with spacing adjustment valves, which adjust the spacing between the two sets of transverse straightening wheels 14 and the two sets of longitudinal straightening wheels 15.

[0024] During processing, the pipe is inserted into the bending seat 6 through the placement groove 7 and extends through to the clamping and rotating mechanism 4. The pipe passes sequentially through the transverse straightening wheel 14 and the longitudinal straightening wheel 15, which straighten the pipe to ensure its straightness. The clamping and rotating mechanism 4 clamps one end of the pipe. The rotating sleeve 8 drives the rotating ring 9 to rotate, causing the bending block 10 to bend the pipe. The lifting ring 13 drives the rotating ring 9 to rise and fall, allowing the bending block 10 to pass around the middle of the pipe, enabling the bending block 10 to bend the pipe from both sides in different directions. The moving seat 3 drives the clamping and rotating mechanism 4 to move, which in turn pushes the pipe to move and rotate, performing multi-segment bending and achieving rapid pipe bending processing.
