It should be noted that: the standard is shown in fig. 1, where the right side in the drawing is the front end, the left side in the drawing is the rear end, and the direction perpendicular to the drawing is the left and right sides, where the direction of incidence into the drawing is the right side, and the direction of outward extension from the drawing is the left side.

The caterpillar track combined drawing machine is used for drawing a pipe, the diameter and the wall thickness of the pipe are reduced, a short thick pipe is drawn into a long thin pipe, the pipe can be clamped through the outer caterpillar track 210, the clamped pipe is drawn along with the transmission of the outer caterpillar track 210, uninterrupted friction force exists between the outer caterpillar track 210 and the support frame 200 during transmission, the support frame 200 and the outer caterpillar track 210 are greatly abraded and can generate larger heat after long-time use, the friction force is overcome, a large amount of energy is consumed, the inner caterpillar track 220 is positioned between the outer caterpillar track 210 and the support frame 200, the outer caterpillar track 210 is driven outside the inner caterpillar track 220, the contact area between the outer caterpillar track 210 and the inner caterpillar track 220 is small, and accordingly less abrasion is caused, the clamp nozzle device 300 is used for clamping the pipe at the initial stage of pipe drawing, and then starts to move with the pipe, and the outer caterpillar track 210 can be stably drawn, the movement of the plier nozzle device 300 collides with the support frames 200, so that the upper and lower support frames 200 can be relatively opened and closed in the vertical direction, and the movement facilitates the movement of the plier nozzle device 300 and the clamping and drawing of the pipe. Referring to fig. 4 and 5, sprockets 240 for controlling the transmission of the outer track 210 are disposed on both sides of the support frame, a plurality of tie-pull molds 212 having mold grooves 211 are disposed on the outer track 210, the outer track 210 clamps the pipe in the mold grooves 211 when the pipe is pulled, the inner track 220 is composed of rollers 221 and outer link plates 222, the rollers contact the outer track 210 and the support frame 200, and the friction between the outer track 210 and the inner track 220 is a rolling friction. The track shoe with the co-drawing die 212 can clamp a pipe, when the outer track 210 is in transmission, friction force can be generated between the outer track 210 and the inner track 220, the rollers 221 can be driven to rotate under the action of the friction force, the inner track 220 consisting of the rollers 221 can be in transmission along the periphery of the support frame 200 while the outer track 210 is in transmission due to the fact that the rollers 221 and the support frame 200 have large friction force, a certain relative sliding can be generated between the outer track 210 and the inner track 220, however, obviously, the generated friction force is lower, the abrasion between the outer track 210 and the rollers 221 is extremely small, the long-time use can be kept, the abrasion is not generated, and the overheating condition is not easy to occur.

The method for controlling the transmission of the outer crawler 210 by the chain wheel 240 is as follows: the outer crawler belt 210 is provided at both sides thereof with a plurality of supporting protrusions 230, the supporting protrusions 230 are caught in tooth grooves 241 of a sprocket 240, and the sprocket 240 drives the outer crawler belt 210 to rotate by engaging with the supporting protrusions 230. By such a drive, the sprocket 240 does not contact the inner track 220 when rotating.

The stroke of the cylinder is limited, so that the condition for controlling the whole operation process cannot be met, although the outer track 210 can control the displacement of the nipper apparatus 300, the necessary condition for the outer track 210 to control the movement of the nipper apparatus 300 is that the nipper apparatus 300 needs to be close to the outer track 210, so the displacement of the nipper apparatus 300 is divided into two parts, the displacement of the first part is controlled by the tail cylinder assembly, and the displacement of the second part is controlled by the outer track 210.

Further explanation is as follows: referring to fig. 10, the tail cylinder assembly includes a tail cylinder 500 and an insert block 510, a side cylinder 520 assembly is provided on the clamp nozzle device 300, the side cylinder 520 assembly includes a side cylinder 520 and a bolt 530, an insertion hole 540 is provided on the clamp nozzle device 300, the tail cylinder 500 controls the insert block 510 to be inserted into the insertion hole 540, and the side cylinder 520 controls the bolt 530 to be inserted into the insertion hole 540 from the side and tightly clamps the insert block 510.

The method for controlling the supporting frame 200 to move only in the vertical direction comprises the following steps: the eccentric shaft 460 is arranged on the synchronous rotating arm 400, the synchronous rotating arm 400 is connected with the supporting frame 200 through the eccentric shaft 460, the supporting frame 200 is provided with a horizontal elliptical hole 470, and the eccentric shaft 460 extends into the horizontal elliptical hole 470. When the synchronous rotating arm 400 rotates, the eccentric shafts 460 also synchronously rotate, and when the pipe is loosened, the end parts of the eccentric shafts 460 of the upper outer tracks 210 move from the end parts of the horizontal elliptical holes 470 to the highest point of the horizontal elliptical holes 470, and the end parts of the eccentric shafts 460 of the lower outer tracks 210 move from the end parts of the horizontal elliptical holes 470 to the lowest point of the horizontal elliptical holes 470; when clamping a pipe, the end of the eccentric shaft 460 of the upper outer track 210 moves from the highest point of the horizontal elliptical hole 470 to the end of the horizontal elliptical hole 470, and the end of the eccentric shaft 460 of the lower outer track 210 moves from the lowest point of the horizontal elliptical hole 470 to the end of the horizontal elliptical hole 470.
