DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

One end of the rotating seat 52 is fixed to the output end of the rotating drive device 51. An extrusion actuator 53 is installed on the rotating seat 52. The extrusion actuator 53 is used to extrude and block the end of the rack pipe 6 to be blocked. The other end of the rotating seat 52 is supported by a sliding support frame 54. The sliding support frame 54 can slide relative to the workbench 1, and the sliding support frame 54 is supported by the workbench 1. A heating actuator 2 is installed next to the clamping tooling 3. The heating actuator 2 is used to heat the end of the rack pipe 6 to be blocked.

[0026] The sliding support frame 54 includes: a mounting block 541, a support column and a pulley 543. The mounting block 541 is mounted on the end of the rotating seat 52 away from the output end of the rotating drive device 51. The mounting block 541 is equipped with a support column that can rotate around the Y direction. A rotatable pulley 543 is installed at the bottom of the support column, and the pulley 543 is supported by the workbench 1. The support column can rotate around the Y direction relative to the mounting block 541, so that the pulley 543 can rotate in all directions relative to the workbench 1, and the pulley 543 slides more smoothly.

[0027] The rotary drive device 51 includes: a rotary table 511, a rotary shaft 512, a gear 513, a rack 514 and a rotary drive cylinder 515. The rotary drive cylinder 515 is installed on the workbench 1. The output shaft of the rotary drive cylinder 515 is fixed to the rack 514. The rack 514 is meshed with a gear 513. The gear 513 is fixed to the rotary shaft 512. The rotary shaft 512 is fixed to the rotary table 511. The rotary table 511 can be rotatably installed on a carrier frame 10. The rotary table 511 is located above the carrier frame 10. The rotary table 511 is the output end of the rotary drive device 51.

[0028] The rotating shaft 512 passes through the carrier 10, and the carrier 10 is an overhead structure. The gear 513 and the rack 514 are both located inside the carrier 10. The carrier 10 has the function of supporting the rotating platform 511, so that the extrusion actuator 53 can be higher than the bottom of the heating device. The top surface of the carrier 10 also has the effect of preventing impurities from entering the meshing part of the gear 513 and the rack 514 after cutting.

[0029] The cutting device 4 includes: a cutting knife 41, a lifting seat 42, a lifting drive cylinder 43 and a mounting seat 40. One end of the mounting seat 40 is installed on the top of the clamping tooling 3, and the other end of the mounting seat 40 is installed with a lifting drive cylinder 43 located above the end to be blocked of the rack pipe 6. The piston rod of the lifting drive cylinder 43 is fixed to the lifting seat 42, and the cutting knife 41 is installed on the lifting seat 42.

[0030] The mounting seat 40 is detachably connected to the top of the clamping fixture 3 via a connecting mechanism 45. The connecting mechanism 45 enables the mounting seat 40 to be mounted on the top of the clamping fixture 3.

[0031] The connection mechanism 45 includes a clamping bolt, and the mounting seat 40 is provided with a strip hole 400 for the clamping bolt to pass through.

The clamping bolt in the connection mechanism 45 can move in the strip hole 400, thereby adjusting the relative position of the cutting knife 41 and the rack pipe 6, so that the cutting knife 41 can be aligned with the position to be cut on the rack pipe 6.

[0032] The heating device includes: a first linear drive mechanism 21, a first movable seat 22, a second linear drive mechanism 23, a second movable seat 24, a heating actuator 25, a heating tube 26 and a heating cylinder 27. The first linear drive mechanism 21 is installed on the workbench 1. The output end of the first linear drive mechanism 21 is connected to the first movable seat 22. The first linear drive mechanism 21 is used to drive the first movable seat 22 to move in the X direction. The first movable seat 22 is provided with a second movable seat 24 that can move in the Z direction. The second movable seat 24 is connected to the second linear drive mechanism 23. The second linear drive mechanism 23 is used to drive the second movable seat 24 to move in the Z direction relative to the first movable seat 22. The second movable seat 24 is installed with a heating actuator 25. The output end of the heating actuator 25 is connected to the heating tube 26. The heating tube 26 surrounds the heating cylinder 27. The heating cylinder 27 is fixed by the heating tube 26. The heating tube 26 extends toward the direction of the end to be blocked of the rack pipe 6. The first linear drive mechanism 21 drives the first movable seat 22 to move in the X direction, thereby moving the heating cylinder 27 to a position aligned with the rack pipe 6; then, the second linear drive mechanism 23 drives the second movable seat 24 and the heating actuator 25, the heating cylinder 27 and the heating tube 26 to move together, and the heating cylinder 27 is sleeved on the end of the rack pipe 6 to be blocked; finally, the heating actuator 25 heats the heating tube 26, and the heat is transferred to the end of the rack pipe 6 to be blocked through the heating cylinder 27, thereby heating the end of the rack pipe 6 to be blocked.

[0033] The extrusion actuator 53 includes: an extrusion head 531, an extrusion drive cylinder 532 and a guide seat 533. The guide seat 533 can move in the radial direction of the output end of the rotation drive device 51 relative to the rotation seat 52. The extrusion head 531 is installed on the guide seat 533. The extrusion head 531 is used to extrude the end of the rack pipe 6 to be blocked. The guide seat 533 is fixed to the output end of the extrusion drive cylinder 532. When the rotation drive device 51 drives the extrusion actuator 53 to rotate a certain angle, the extrusion head 531 reaches the middle of the end of the rack pipe 6 to be blocked from one side of the rack pipe 6. At this time, the middle of the end of the rack pipe 6 to be blocked is raised, and the other side of the end of the rack pipe 6 to be blocked needs to be squeezed. Therefore, the extrusion drive cylinder 532 is designed to drive the extrusion head 531 to move in the radial direction of the rotating table 511 by driving the guide seat 533 to jump over the raised middle of the end of the rack pipe 6 to be blocked, so as to ensure that the extrusion can be started from the other side of the end of the rack pipe 6 to be blocked, and finally the blocking is achieved.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
