Description

Technical Field

[0001] The invention belongs to the technical field of bimetallic composite material equipment, and in particular relates to a movable device for a copper-aluminum composite track drawing die. Background Art

[0002] As the world pays more and more attention to energy conservation and environmental protection, and the requirements are getting higher and higher, the application of copper-aluminum composite bars is expanding, and the production capacity is becoming increasingly insufficient, mainly concentrated in the low drawing capacity; in order to solve the problem of low drawing efficiency, a series of modifications were made, and finally the copper tube crawler drawing equipment was successfully modified and applied to the drawing production of copper-aluminum composite bars, which greatly improved the production efficiency. However, the disadvantage is that the modified crawler drawing cannot produce six-meter fixed-length finished bars, because the straightness of the produced bars does not meet the requirements. The last process can only be transferred to the hydraulic drawing with low production capacity to ensure the straightness of the material, which seriously restricts the output of the crawler drawing process; at the same time, the existing crawler drawing and mold position are fixed and unchanged, with a distance of only 600mm. The copper-aluminum composite bar will have unstable lateral fluctuations on the crawler, which has a serious unstable effect on the deformation stress of the material in the mold. Summary of the invention

[0003] The invention provides a movable device for drawing a copper-aluminum composite row crawler track, which solves the problem of straightness of the last six meters of finished row of crawler track drawing in the background technology.

[0004] The technical solution of the present invention is achieved as follows: a movable device for drawing a copper-aluminum composite crawler track die comprises a crawler track drawing machine, a straightening machine and a material guide device are arranged on the same horizontal line on the right side of the crawler track drawing machine, a drawing die is arranged on the right side of the crawler track drawing machine, a die bracket is arranged below the drawing die, the front end of the die bracket is fixedly connected to the frame of the crawler track drawing machine, slide rails are arranged on both sides above the die bracket, the lower end of the drawing die is located in the slide rails, the drawing die can slide back and forth along the slide rails, a connecting plate is arranged below the drawing die, the connecting plate is connected to the cylinder piston rod in the die cylinder, the die cylinder is arranged at the rear end of the die bracket, a cylinder fixing seat is arranged at the upper end of the frame of the crawler track drawing machine, a cylinder is arranged on the cylinder fixing seat, two side-by-side guide rollers are arranged below the cylinder, and one of the guide rollers is connected to the adjusting hand wheel.

[0005] The beneficial effects of the present invention are as follows: the present invention uses a movable structure to increase the distance between the mold and the crawler by geometric multiples, and improves the geometric factors by lengthening the distance. This change will reduce the stress effect on the material by several times due to the same geometric change caused by the same force, thereby achieving the purpose of reducing deformation; by setting a guide roller to block the geometric change caused by the crawler pulling force from being transmitted to the mold, the stress change of the material in the mold shaping area is further improved, so that the material molding is more stable. The present invention solves the problem of unstable and unqualified continuous drawing straightness of copper-aluminum composite bars with minor changes and lower costs, thereby achieving the process stability of continuous drawing and cutting of copper-aluminum composite bars, eliminating the inefficient hydraulic drawing in the last process, and greatly improving production efficiency.

[0011] In order to better understand and implement the present invention, the following is a further description of the present invention in conjunction with the accompanying drawings: a movable device for drawing a copper-aluminum composite crawler track, comprising a crawler drawing machine 1, a straightening machine 3 and a material guide device 4 are arranged on the same horizontal line on the right side of the crawler drawing machine 1, a drawing die 2 is arranged on the right side of the crawler drawing machine 1, a die support 11 is arranged below the drawing die 2, the front end of the die support 11 is fixedly connected to the frame 14 of the crawler drawing machine 1, a slide rail 10 is arranged on both sides above the die support 11, and the lower end of the drawing die 2 is located on the slide The drawing die 2 can slide forward and backward along the slide rail 10. A connecting plate 13 is provided below the drawing die 2. The connecting plate 13 is connected to the cylinder piston rod 15 in the die cylinder 6. The die cylinder 6 is arranged at the rear end of the die bracket 11. A cylinder fixing seat 12 is provided at the upper end of the frame 14 of the crawler drawing machine 1. A cylinder 7 is provided on the cylinder fixing seat 12. Two side-by-side guide rollers 9 are provided below the cylinder 7. One of the guide rollers 9 is connected to the adjusting hand wheel 8. The distance between the two guide rollers 9 can be adjusted by adjusting the hand wheel 8.

[0012] Specifically, before drawing, one end of the track composite material 5 is passed through the material guide device 4 and the straightening machine 3 into the drawing die 2, and then enters the track drawing machine 1 from the drawing die 2. Before pulling, the distance L1 between the discharge port of the drawing die 2 and the track 16 of the track drawing machine 1 is 600mm. After adjustment, the drawing die 2 is driven by the die cylinder 6 and moves to the right along the slide rail 10 to the position where the distance L2 between the discharge port of the drawing die 2 and the track 16 of the track drawing machine 1 is 1950mm. The cylinder 7 drives the two guide rollers 9 to move downward, and the two guide rollers 9 move to both sides of the track composite material 5. By adjusting the hand wheel 8, the distance between the two guide rollers 9 is suitable for the width of the track composite material 5. At this time, the straightening machine 3 starts to correct, and the straightened track composite material 5 moves to the left and moves into the drawing die 5 for drawing. The drawn track composite material 5 is sawed to the discharge size by the track drawing machine 1.

[0013] The distance between the improved drawing die and the track increases geometrically, from 600mm to 1950mm, reducing the impact of the fluctuation of the copper-aluminum composite row on the track; the lengthened distance makes it difficult to wear the die. In order not to increase the difficulty of wearing the die, the die position is designed to be movable, so that the initial position of the die can be kept unchanged, and the original die-wearing mechanism is retained without increasing the difficulty of wearing the die. The goal of the mold being movable can be achieved by driving the die forward and backward on the track through the oil cylinder. At the same time, a guide roller is added. After the die moves to a long distance, the guide roller is driven by the cylinder to move to the set appropriate guide position, and the hand wheel is adjusted to adapt to the width of the material. This device effectively limits the lateral displacement of the material, plays a certain blocking role in the lateral wave transmission of the copper-aluminum composite row, and reduces its impact on the deformation stress of the material.
