Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing equipment, and in particular to a tracked drawing machine. Background Technology

[0002] The production process of aluminum tubes includes heat treatment of aluminum columns, hot sawing, pultrusion molding, and straightening. After pultrusion molding, the aluminum tubes require a drawing process to improve their precision. Existing equipment first inserts the end of the aluminum tube onto an inner mold, then the entire tube is inserted onto an outer mold. A gripping mechanism holds the aluminum tube and draws it. The cooperation of the inner and outer molds reduces the tube diameter and improves precision. However, this drawing process is intermittent; after the gripping mechanism draws a section of the aluminum tube, it needs to reset and repeat the process of inserting the inner and outer molds before the next drawing can begin. This equipment has the following drawbacks: 1. Low drawing efficiency, and it cannot meet the requirements for continuous aluminum tube drawing; 2. Each section of aluminum tube requires discarding some material from the front end, resulting in waste; 3. Insufficient drawing precision, affecting subsequent use. Therefore, a tracked drawing machine is urgently needed to solve these problems. Utility Model Content

[0043] The mold base 200 is located at the front end;

[0044] The drive unit 300 is connected to the first belt pulling device 400 and the second belt pulling device 500;

[0045] The first belt pulling device 400 and the second belt pulling device 500 are connected to the rear end of the mold base 200 and are arranged opposite each other in the vertical direction.

[0046] The adjusting device 600 is connected to the first belt pulling device 400 and the second belt pulling device 500 respectively, and is used to adjust the distance between the first belt pulling device 400 and the second belt pulling device 500.

[0047] An aluminum tube is inserted between the first belt pulling device 400 and the second belt pulling device 500 to pull the aluminum tube through the mold base 200.

[0048] 1) In this utility model, the pultruded aluminum tube is fed into the die holder 200. Specifically, the die holder 200 includes an inner die and an outer die. The aluminum tube passes through the inner die, and then the inner die and the aluminum tube are passed together through the outer die. It is then pulled between the first belt pulling device 400 and the second belt pulling device 500. The distance between the first belt pulling device 400 and the second belt pulling device 500 is adjusted by the adjusting device 600 so that the first belt pulling device 400 and the second belt pulling device 500 can press against the aluminum tube. Then, the driving device 300 is activated to drive the first belt pulling device 400 and the second belt pulling device 500 to rotate. Figure 1 Taking the perspective of the first belt pulling device 400 as an example, the driving device 300 drives the first belt pulling device 400 to rotate counterclockwise and the second belt pulling device 500 to rotate clockwise, thereby pulling the aluminum tube backward; after being squeezed by the die holder 200, the diameter and wall thickness of the aluminum tube are changed, thus completing the pulling process of the aluminum tube.

[0049] 2)Reference Figures 1-2 In some embodiments, the drive device 300 includes a variable frequency motor 310 and a dual output shaft reducer 320 connected to the output end of the variable frequency motor 310. The first output shaft of the dual output shaft reducer 320 is connected to the first belt pulling device 400, and the second output shaft is connected to the second belt pulling device 500. By setting a dual output shaft reducer 320, the first belt pulling device 400 and the second belt pulling device 500 can be driven simultaneously.

[0050] 3)Reference Figures 1-3 as well as Figure 5 In some embodiments, a tracked drawing machine further includes a first straightening device 710 docked to the front end of the die holder 200 for straightening the front end of the aluminum tube; and / or, it further includes a second straightening device 720 docked between the die holder 200 and the first belt drawing device 400 and the second belt drawing device 500 for straightening the rear end of the aluminum tube.

[0051] Specifically, the first straightening device 710 includes two sets of first straightening wheel assemblies 711, one set of second straightening wheel assemblies 712, one set of third straightening wheel assemblies 713, and two sets of fourth straightening wheel assemblies 714 arranged sequentially.

The second straightening wheel assembly 712 and the third straightening wheel assembly 713 are located on both sides of the aluminum tube and are staggered along the length of the aluminum tube, which can straighten the front end of the aluminum tube. The second straightening device 720 includes two sets of fifth straightening wheel assemblies. Each fifth straightening wheel assembly includes a wheel body 721, a lead screw, and an adjustment knob 722. Rotating the adjustment knob 722 drives the lead screw to rotate and converts it into linear motion of the wheel body 721, which can straighten the rear end of the aluminum tube.

[0052] 4)Reference Figures 1-2 as well as Figure 4 In some embodiments, the mold base 200 is connected to the frame 100 via a fine-tuning device 800 for adjusting the position of the mold base 200 in the horizontal and / or vertical directions;

The ventilation holes are connected to the cooling channel and connected to an external air source. The external air source introduces air into the cooling channel through the ventilation holes, thereby achieving air cooling of the aluminum tube. This can prevent the aluminum tube from being too hot after being drawn by the mold seat 200, which could damage the first belt pulling device 400 and the second belt pulling device 500.
