How to cut the PTFE hose to avoid damaging the pipe？

PTFE tube is generally treated by a cutting machine. Cutting machine cutting PTFE tube can effectively prevent tube deformation. There is nothing more painful than stabbing a finger with the worn edge of a braided hose. The pain of dealing with these things is worth it, especially when you need a durable high-voltage cable. Nothing can match the wear resistance of stainless steel braided hose. There are some tips you need to know when you need to cut the braided hose.

Polytetrafluoroethylene (PTFE) pipe is a kind of high-quality plunger extrusion pipe. The special processing technology is adopted to make the steel pipe and plastic pipe closely combined. It can bear positive pressure of 1.6Mpa and negative pressure of 77kpa. It can be used normally from - 60 ℃ to + 260 ℃. It has reliable and excellent corrosion resistance. It can transport strong corrosive gas and liquid under high temperature, which can not be replaced by other pipes It has excellent chemical stability, can withstand all strong acids, strong bases, strong oxidants, and does not interact with various organic solvents. After the PTFE pipe is manufactured, the length of the pipe needs to be cut. The existing PTFE pipe cutting device, after cutting the polytetrafluoroethylene pipe, also needs the staff to move to the side of the workbench to push the pipe, It is a waste of time and inconvenient to cut the pipe. Therefore, a cutting device for the manufacture of polytetrafluoroethylene pipe is proposed.

Technical implementation elements:

The purpose of the utility model is to provide a cutting device for manufacturing polytetrafluoroethylene pipe, so as to solve the problems raised in the background technology.

In order to achieve the above purpose, the utility model provides the following technical scheme: a cutting device for the manufacture of polytetrafluoroethylene pipes, including a worktable, the upper surface of the worktable is provided with a bracket, the center of the lower surface of the support is fixedly connected with a hydraulic cylinder, the output shaft of the hydraulic cylinder is fixedly connected with a cutter, and the center of the upper surface of the worktable is provided with a first groove The first groove is located directly below the cutter, one side of the first groove is provided with a second groove, the second groove is provided with a first plate body, the outer wall of the first plate body is uniformly installed with a first slide block, the first sliding block slides in the second groove, one side of the first plate body away from the first groove is fixedly connected with a rocker The front surface of the worktable is provided with a third groove, the rocker is located in the third groove, the first groove is provided with a limit plate, one side of the limit plate far away from the first groove is fixedly connected with a bearing, the back surface of the worktable is provided with a threaded through hole, and the screw rod is connected with the thread in the threaded through hole.

As a further optimization of the technical scheme, a fourth groove is arranged on one side of the worktable, a second plate body is arranged inside the worktable, the front and rear sides of the second plate body are symmetrically and fixedly connected with a second slider, the second sliding block slides in the fourth groove, and the upper surface of the second plate body is uniformly and fixedly connected with a support plate.

Compared with the prior art, the utility model has the following beneficial effects: after the pipe is cut, the rocker is turned anticlockwise, the rocker rotates in the third groove, and the rocker drives the first plate body to rotate so that the first plate body slides in the second groove through the first slide block. Because the first plate body is close to the pipe material, when the first plate body rotates, it can drive the pipe to move forward After the pipe is cut, it is not necessary for the staff to move to promote the occurrence of pipe material, which saves time and effort, and is convenient for pipe cutting.

One aspect that beginners often make mistakes in weaving hose is cutting. Once the braid starts to wear, it's almost impossible to deal with it, frustrating you and bleeding your fingers. Not to mention, it is not possible to place fittings on a hose that is worn at both ends.

Whatever you do, don't use a hacksaw. This is the worst tool for cutting a braided hose. There are three kinds of cutting tools, one is sawing, the other is sawing.

make preparation

You need to prepare before you cut the hose. Wrap a few inches of hose tightly with electrical tape or masking tape. Then draw your cutting line on the tape. The tape will help to prevent abrasion of the braid during cutting and assembly. Wrapping the hose with tape helps prevent wear at both ends and provides you with a clean place to mark the cut.

Cutting options

Band saws are not the best option, but if you take your time, it can. You have to walk very slowly, and at the end, as you pass through the fabric, slowly roll the hose onto the saw blade so you don't get any worn wires. It is a good way to cut off the hose with the cutting wheel, and the work can be completed without too many problems. You can hold the hose in one hand and cut it with the other, but it's better to use a vise so that you have better control over the cutting wheel. Walk slowly. Be careful not to put too much pressure on the hose, or it will cause wear. The cut-off wheel works properly, you can cut off the hose under the car is necessary. Take your time. Take your time. Take your time.

A good tool is a saw with a grinding wheel. You'll get a good, clean cut without wear and tear, and the chopper saw has a built-in fixture, so you don't have to worry about missing the cut. It's better to have a saw that holds the hose in place so you can control it completely and you can get a clean cut.

This kind of wear often happens, so be careful not to cut too fast. You can trim these with wire cutters, but it's tricky.

Once the hose has been cut, place the remaining hose and leave the tape at the end. The thing you want to use needs to be assembled, which we will cover in another article. Do not remove the tape for the time being, or it will cause the fabric to loosen, which is a bad thing.
