Double-end automatic stretcher

Abstract

The invention discloses a double-end automatic stretcher. The double-end automatic stretcher comprises stretching dies and stretching trolleys, wherein stretching block of the stretching dies are provided with a plurality of taper holes with the diameters gradually reduced, and a cutting rope penetrates through the taper holes to complete stretching; the stretching trolleys are used for clamping one end of the cutting rope so as to provide power for stretching of the cutting rope, the two stretching dies are symmetrically arranged, and the two stretching trolleys are arranged and distributed on the two sides of the two stretching dies correspondingly; and during use, the cutting rope is pulled through the stretching trolleys on the two sides correspondingly, so that the cutting rope gradually penetrates through the taper holes, and then the cutting rope is gradually stretched to the preset size. According to the double-end automatic stretcher, the cutting rope is pulled back and forth through the two stretching trolleys, the cutting rope is pulled back and drawn through the taper holes of the two stretching dies, therefore the cutting rope can be rapidly machined, and the size can be effectively reduced; and the double-end automatic stretcher can achieve automation, so that the production efficiency is greatly improved, the cost is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to the processing technology of pyrotechnics, in particular to the processing of cutting cables, in particular to a double-head automatic stretching machine. Background technique [0002] The processing process of the existing cutting wire is roughly as follows: the two ends of the relatively thick pipe filled with chemicals (parameters are shown in Table 1.1) are sharpened, passed through the tapered drawing die, and the drawing force is provided by mechanical power equipment, and the diameter of the thick pipe is Decrease in turn, and finally reach the required size, and the number of drawing times can reach up to 48 times. Decompose the existing process, specifically including the following steps: [0003] ① One product is stretched at a time. After the stretching is completed once, it needs to be manually transferred and turned around before stretching; [0004] ② Manually replace the mold each time; [0005] ③Manual clampi...

AI Technical Summary

Problems solved by technology

[0007] ⑤ The stretching speed needs to be manually adjusted each time;

[0008] ⑥The movement position of the stretching trolley needs manual intervention and adjustment, and the product may fall when the product is pulled;

[0009] ⑦ There is no safety protection in the whole stretching process;

[0014] ① There are many manual intervention links (tip rolling, mold replacement, stretching manual clamping, manual adjustment of stretching speed), labor intensity of workers is high, efficiency is low, and no more than 12 products are processed per shift;

[0015] ②The degree of automation is low, the speed of the stretching process is manually adjusted, there is no tension control, and the product consistency is poor;

[0016] ③ The degree of informatization is low, and information such as processing parameters (tension, indexing) and product processing progress cannot be shared and saved in time;

[0017] ④ Manually replace the mold each time, and it needs to be replaced many times manually, the efficiency is low, and the risk of human error is high;

[0018] ⑤ The head rolling mechanism is completely naked, which poses a safety risk;

[0019] ⑥The rolling head mechanism has no rolling groove, no mark and guide device, which is prone to errors
