Problems solved by technology

[0003] The thick pipe is produced first, and then the thick pipe is drawn into a thin pipe. After drawing, the pipe blank will become longer, the diameter will become smaller, and the pipe wall will become thinner. It is easier to produce a shorter thick pipe, and directly The production of longer thin pipes requires higher equipment, so it is a good way to produce pipes by drawing. In the prior art, the drawing equipment is to directly print the pipes into the drawing machine for drawing, and the production There are certain restrictions on the length of the pipe, and the quality of the pipe produced is average

Embodiment 1

[0057] refer to figure 1 and 2 , the crawler-type pulling unit, including two crawler pulling machines 100, the crawler pulling machine on the rear side is the output end of the pipe, the crawler pulling machine on the front side is the input end of the pipe, and the two crawler pulling machines 100 are arranged between There is a linear compensation device 200 for balancing the transmission speed of pipes. The crawler puller 100 includes a frame 101. The frame 101 is provided with two support frames 110 up and down. The outside of the support frame 110 is provided with clamping and drawing pipes. The crawler assembly, the pipe entry end of the crawler puller 100 on the rear side is provided with a mold assembly 300 for forming the pipe and adjusting the output direction of the pipe, and a movable jaw device 400 is provided between the upper and lower support frames 110. The device 400 is used to clamp the end of the pipe protruding into the frame 101, and pull the pipe to mo...

Embodiment 2

[0065] This embodiment proposes a clamping mechanism that controls the movement of the support frame 110. Specifically: referring to Figures 11 and 12, the right side of the frame 101 is provided with a clamping mechanism that controls the movement of the upper and lower support frames 110. Tight mechanism comprises the synchronous rotating arm 160 that is connected with support frame 110, is provided with 1 / 4 gear 161 on the synchronous rotating arm 160, is provided with hydraulic cylinder 150 on the right side of frame 101, and hydraulic cylinder 150 end is connected telescopic seat 151, telescopic The upper and lower surfaces of the seat 151 are provided with a rack 152 meshing with a quarter gear 161. When the telescopic seat 151 stretches, the synchronous rotating arm 160 is controlled to rotate, and the upper and lower supporting frames 110 are relatively opened and closed in the vertical direction. After the upper and lower support frames 110 are far away from each other...

Embodiment 3

[0071] This embodiment proposes a structure for adjusting the speed of the pipe input end and output end: refer to Figure 14 and 15 , the linear compensation device 200 comprises a main frame, the main frame is divided into a middle frame 210 and a side frame 220 located on both sides of the middle frame 210, the middle frame 210 is provided with a mobile platform 230, and the side frame 220 A plurality of roller devices 240 for guiding the transmission of pipes are distributed on the mobile platform 230 at intervals. When the transmission speed of the crawler puller 100 at the front end is greater than the displacement of the crawler puller 100 at the rear end, the pipe deforms and pushes the movable table 230 to bend toward the pipe. According to the displacement of the mobile platform 230, the speed of pipe material transmission is adjusted.

[0072] The middle frame 210 is provided with a cylinder base 250, and the cylinder base 250 is provided with a position sensor 600...

Abstract

The invention discloses a crawler-type combined drawing unit, and belongs to the field of machining. By means of the crawler-type combined drawing unit, the quality of produced pipes is improved, andultra-long pipes can be produced. The crawler-type combined drawing unit comprises two crawler combined drawing machines, wherein the crawler combined drawing machine at the rear side is a pipe outletend, and the crawler combined drawing machine at the front side is a pipe inlet end; a linear compensation device for balancing the conveying speed of the pipes is arranged between the two crawler combined drawing machines; each crawler combined drawing machine comprises a machine frame; each machine frame is provided with an upper supporting frame and a lower supporting frame; a crawler assemblyfor clamping and drawing the pipes is arranged on the outer sides of the supporting frames; a mold assembly for molding the pipes and adjusting the pipe output direction is arranged at the pipe inletend of the crawler combined drawing machine at the rear side; movable twin hook devices are arranged between the upper supporting frames and the lower supporting frames; and the twin hook devices areused for clamping the ends, extending into the machine frames, of the pipes and drawing the pipes to move so as to complete initial drawing.

Description

【Technical field】 [0001] The invention relates to the field of mechanical processing, in particular to a crawler-type combined drawing unit. 【Background technique】 [0002] Drawing is a plastic processing method that uses external force to act on the front end of the drawn metal to pull the metal blank out of a die hole smaller than the section of the blank to obtain a product of corresponding shape and size. [0003] The thick pipe is produced first, and then the thick pipe is drawn into a thin pipe. After drawing, the pipe blank will become longer, the diameter will become smaller, and the pipe wall will become thinner. It is easier to produce a shorter thick pipe, and directly The production of longer thin pipes requires higher equipment, so it is a good way to produce pipes by drawing. In the prior art, the drawing equipment is to directly print the pipes into the drawing machine for drawing, and the production There is a certain limit to the length of the pipe, and the...
