[0002] In current technology, pipe cutting and bending processes are often carried out separately, which affects production efficiency. Pipes need to be transferred and positioned multiple times in cutting and bending equipment, with many operating steps and high labor intensity. This also leads to a high equipment idle rate, occupies a large workshop area, and increases production costs. In addition, current cutting / bending equipment uses a simple clamping claw structure for pipes, which makes it difficult to maintain a stable clamping posture for the pipes, affecting the cutting and bending effects.

[0003] The utility model patent with publication number CN211469737U was disclosed on September 11, 2020, and its name is a laser cutting machine plate and pipe feeding device, which includes a transmission mechanism and a bending auxiliary mechanism. The bending auxiliary mechanism is fixedly installed on the transmission mechanism, and the friction between the bending roller and the conveyor belt provides the conveyor belt with upward movement force to reduce the load of the active motor. When the plate and pipe are transported to the connection between the inclined section and the horizontal section, part of the plate and pipe is close to the conveyor belt of the inclined section, and the other part is tilted above the conveyor belt of the horizontal section. The infrared sensor senses that the end of the plate and pipe is tilted at a predetermined height, and the control cylinder starts and lifts the connecting rod from the bottom through the push rod to lift the plate and pipe upward, so that the inclined plate and pipe return to the horizontal state, and are transported to the next step under the action of the continuously running conveyor belt. The laser cutting machine plate and pipe feeding device cannot solve the technical problems recorded above. Summary of the invention

[0023] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0024] like Figure 1 As shown, the laser tube cutting and bending machine comprises a machine platform 1, a clamping seat 2 is provided on the machine platform 1, the clamping seat 2 comprises a clamping jaw 6, a cutting head 7 is provided above the end of the machine platform 1, and a tube bending mechanism is provided at the end of the machine platform 1. The clamping jaw 6 fixes one end of the pipe fitting, and the clamping seat 2 is movable on the machine platform 1, so that the cutting length and bending position of the workpiece can be changed, and a hole can be opened on the workpiece in cooperation with the cutting head 7. A motor is built in the clamping seat 2, and the motor is connected to the clamping jaw 6 to realize the rotation of the clamping jaw 6, and the bending direction of the pipe fitting can be switched in cooperation with the tube bending mechanism.

[0025] like Figure 4-1 to Figure 5-2 As shown, the pipe bending mechanism includes a base 3, a bending shaft 14 is provided on the base 3, a bending die 8 is provided on the bending shaft 14, a clamping die seat 16 is also sleeved on the bending shaft 14, a clamping die head 9 is provided on the clamping die seat 16, and the clamping die head 9 is located on one side of the bending die 8. After the workpiece is clamped by the bending die 8 and the sliding die 10, its end passes through the two, and the clamping die head 9 can move horizontally on the clamping die seat 16 until it contacts the bending die 8, and the clamping die seat 16 rotates around the bending shaft 14, and the workpiece is bent and formed between the bending die 8 and the clamping die head 9.

[0026] like Figure 4-1 to Figure 5-2 As shown, a mounting seat 4 is fixedly connected to one side of the base 3, a sliding die 10 is provided on the top of the mounting seat 4, a sliding groove 13 is provided on the sliding die 10, and the sliding groove 13 is arranged parallel to the axis of the clamping jaw 6. The sliding die 10 provides additional clamping for the workpiece to ensure the stability of the workpiece position, and plays an axial guiding role in the continuous bending process of the pipe fitting, further ensuring the forming effect. When the workpiece is bent, one end of it is fixed by the clamping jaw 6, and the other end is clamped and fixed between the sliding die 10 and one side of the bending die 8. After both ends of the workpiece are fixed, the bending process can be carried out.

[0027] like Figure 1As shown, a clearance groove 22 is provided at one end of the machine 1, and the base 3 is located in the clearance groove 22. The clearance groove 22 is an inclined surface structure. The clearance groove 22 is used in conjunction with the base 3, and a guide and fixing structure are provided on the contact surface of the two, so that the base 3 can slide along the inclined surface of the clearance groove 22. When the pipe fitting does not need to be bent, the base 3 retracts to make space for the cutting and blanking process of the pipe fitting, saving space for the equipment.

[0028] like Figure 4-1 to Figure 5-2 As shown, the bending die 8 includes a bending groove 11, one end of which is arranged parallel to the slide groove 13; the clamping die 9 includes a clamping groove 12, and the slide groove 13, the bending groove 11 and the clamping groove 12 are at the same height. The bending groove 11 is circumferentially distributed on the outer edge of the bending die 8, and one end thereof is designed to be arranged parallel to the slide groove 13, which is used to ensure the horizontal alignment of the workpiece after the bending die 8 and the slide die 10 are clamped, and to ensure the subsequent bending and forming effect. The above structure ensures the horizontal position of the workpiece when it is clamped and during the bending process.

[0029] like Figures 1 to 3 As shown, a platform 18 is provided above the end of the machine 1, a mounting plate 19 is provided on the platform 18, a vertical guide rail 20 is provided on the mounting plate 19, a slider 21 is provided on the vertical guide rail 20, and the cutting head 7 is fixedly connected to the slider 21. The platform 18 increases the installation height of the cutting head 7, does not affect the linear movement process of the workpiece driven by the clamping seat 2, the mounting plate 19 moves horizontally on the platform 18, and the slider 21 moves vertically on the guide rail 5, realizing the lateral and vertical movement of the cutting head 7 to meet the hole opening requirements.

[0030] like Figure 5-1 and Figure 5-2 As shown, a limit block 17 is provided on the bending shaft 14, and the bending die 8 is provided on the limit block 17; a mounting platform 15 is provided on one side of the base 3, the bottom end of the bending shaft 14 passes through the mounting platform 15, and one end of the clamping die seat 16 abuts against the mounting platform 15. The above structure has an axial limit effect on the bending die 8 and the clamping die seat 16, thereby improving the stability of the horizontal posture during the workpiece clamping and bending process, and further improving the reliability of cutting and bending forming.

[0031] like Figure 1 As shown, a guide rail 5 is provided on the machine platform 1, and the clamping seat 2 is provided on the guide rail 5. The guide rail 5 guides the movement of the clamping seat 2 to reduce the movement resistance.

[0032] like Figure 1 As shown, the guide rails 5 are arranged in pairs. The guide rails 5 arranged in pairs improve the accuracy of the moving direction of the clamping seat 2.

[0033] The implementation method is as follows: when cutting a pipe fitting, the pipe fitting is clamped by the clamping claw 6, the clamping seat 2 moves along the guide rail 5 to make the pipe fitting move in a straight line, and the cutting head 7 cuts and the pipe fitting moves alternately to complete the pipe fitting cutting process. For bending of large-sized pipe fittings, the base 3 moves on the inclined plane to make the sliding die 10, the bending die 8 and the clamping die 9 coplanar with the pipe fitting, the clamping seat 2 moves along the guide rail 5 to extend the end of the pipe fitting beyond the clamping die 9, the sliding die 10 moves to place the pipe fitting between the sliding groove 13 and the bending groove 11, and then the clamping die 9 rotates to form and bend the pipe fitting between the clamping groove 12 and the bending groove 11. For pipes that need to be bent continuously, it is only necessary to reset the sliding die 10 and the clamping die 9, and move the clamping seat 2 along the guide rail 5 to allow the pipe to continue to move and extend to a specified length, so that the second bending position of the pipe is clamped by the sliding die 10 and the clamping die 9. The bending process is the same as above. If the pipe needs to change the bending plane to form a special-shaped part during continuous bending, it is only necessary to rotate the clamping jaw 6 to rotate the pipe to a certain angle. For bent pipes that need to be opened, when the pipe is clamped by the sliding die 10 and the bending die 8 in the above process, the clamping seat 2 and the cutting head 7 follow the movement to meet the opening requirements.

[0034] The laser tube cutting and bending machine integrates the cutting and bending functions into one, and the two can be used synchronously or independently to meet the cutting and bending needs of the workpiece, eliminating the tedious operation of reciprocating the transfer of pipes between different processes, and improving production efficiency. The setting of the clearance groove 22 facilitates the switching of the tube bending mechanism between the working and non-working states, so as to achieve space clearance in the tube cutting and blanking process; the tube bending mechanism is also provided with a bending die 8, a clamping die 9 and a sliding die 10, and its structural design is reasonable, and the clamping stability of the tube is high, which ensures the reliable cutting and bending forming effects and improves the product quality.

[0035] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
