Problems solved by technology

Although this technical solution can realize the cutting of the braided pipe, the braided layer on the outer surface of the pipe is fused by heating the copper briquetting block. When the clamping part is fused, the heat energy can no longer be transferred to the area between the two clamping parts, so the braiding layer at the cutting part of the saw blade still exists continuously, so that in the process of sawing with the saw blade, the consumption The time is long and the service life of the saw blade is short, and it is often easy to stop the machine to change the saw blade, which seriously affects the production efficiency; the braid layer is prone to loosening at the fusing part and the sawing part, which seriously affects the subsequent operation and processing efficiency

Embodiment

[0026] Please refer to Figure 1-Figure 6 , the present embodiment is an automatic fixed-length cutting equipment 100 for stainless steel polytetrafluoroethylene braided pipe, which includes a feeding mechanism 1 , a traction straightening mechanism 2 , a counterweight storage mechanism 3 and a melting and cutting mechanism 4 .

[0027] The feed feeding mechanism 1 can adopt a horizontal rotating disk or a bearing frame. Place the roll-shaped pipe reel on the horizontal rotating disk. When one end of the pipe is pulled forward, the pipe reel rotates with the horizontal rotating disk to realize discharging. Or set the roll-shaped pipe reel on the bearing frame through the pin shaft. When one end of the pipe is pulled forward, the pipe reel rotates vertically to realize discharging. A servo motor may also be provided at the lower end of the horizontal rotating disk to drive the horizontal rotating disk to rotate and automatically feed. Similarly, the above-mentioned pin shaft ...

Abstract

The invention discloses automatic fixed-length cutting equipment for a stainless steel-teflon braided tube. The automatic fixed-length cutting equipment comprises a feed conveying mechanism, a traction straightening mechanism, a counterweight material storage mechanism and a fusion cutting mechanism. The fusion cutting mechanism comprises a fusion resistance unit and a saw cutting unit. The fusionresistance unit comprises a fifth air cylinder, a sixth air cylinder, a left solder resistance clamping assembly, a right solder resistance clamping assembly and a high-pressure gas blowing device, wherein the driving direction of the fifth air cylinder is opposite to that of the sixth air cylinder; the left solder resistance clamping assembly is driven by the fifth air cylinder, and the right solder resistance clamping assembly is driven by the sixth air cylinder; and the high-pressure gas blowing device conducts gas blowing cooling on the fused portion of the tube. The structure of the leftsolder resistance clamping assembly is the same as that of the right solder resistance clamping assembly, and a gap is reserved between the left solder resistance clamping assembly and the right solder resistance clamping assembly. The left solder resistance clamping assembly comprises an upper clamping electrode block and a lower clamping electrode block which are used for clamping the tube andare further electrically connected with a power supply unit. The saw cutting unit comprises a cutting blade which moves up and down and further makes self-rotation movement. The cutting blade goes deep into the gap. The automatic fixed-length cutting equipment is high in cutting efficiency and cutting precision, and a fusion ring is formed on the cut-off surface so that the scattering phenomenon can be avoided.

Description

【Technical field】 [0001] The invention belongs to the technical field of automobile pipeline manufacturing, in particular to an automatic fixed-length cutting equipment for stainless steel polytetrafluoroethylene braided pipes. 【Background technique】 [0002] Stainless steel PTFE braided pipes are used in automobile brake systems to flexibly connect low-carbon steel pipes, and can be connected in a small space. [0003] Automobile braking system is a very important safety component system. The whole system has very high requirements for leakage and high pressure resistance, and the braided pipe is no exception. This braided pipe is composed of stainless steel braided layer and PTFE layer. In practical applications, Insert the low-carbon steel pipe after the end is formed into the braided pipe, and then buckle and fix the outside. These process steps have very high requirements on the length of the cut-to-length braided pipe and the flatness and appearance of the end face. ...
