Abstract

The subject of the solution is a cutting device plastic pipes with an addition to the straightforward motion that is can be attached to the pipe cut from plastic mass in the landfill and cut the exact part of the pipe without any further treatment for welding.

Description

The invention relates to a device for cutting plastic pipes

Plastic tubes are cut by hand saw in the landfill before welding · After cutting off the necessary part of the pipe, the cut is adjusted on a band saw or on a stable hand saw in the stand, where they can produce any bevels for various knees and preparation of tubes before welding is very laborious, lengthy and demanding on physical work ·

The above-mentioned disadvantages are overcome by a device for cutting plastics pipes with a cut perpendicular or inclined to the axis of the pipe consisting of a prism, a flat guide, a sleeve, a bolt, pins, a pin, a web and an angle. at least one flat guide is fixed to the angle prism, on which a self-locking sleeve is fitted, provided with a bolt, in which a pivot is rotatably mounted, which is connected to the interchangeable prisraern by means of a pin; of the second web is rotatably mounted with adjustable position angle with pin on which the cutting mechanism is rotatably mounted ·

The cutting mechanism consists of a swivel cube which is mounted on a pivot and in which a jig for linear movement with a normal hand drill is attached to which the saw frame and the saw guide are fixed ·

The device for cutting plastic pipes with the method of cutting with this device allows to cut the required part of the pipe β directly in the pipe dump by possible bevel without further modification of the A-gáwf pipe including the cutting of the pipe for welding various elbows ·

An exemplary embodiment of the device according to the invention is shown in the accompanying drawings, namely in FIG. 1 and FIG. 2. The cutting mechanism is shown in FIG. 3 around the protected device * Around the other

FIG. 1 shows a front view of the device according to the invention.

At least one flat guide 2 is mounted on the angle bar 1, on which the self-locking sleeve 2 »is provided with a screw in which the pin 2 · 5ep 2 is rotatably mounted, connected to the replaceable shaft 6 by means of a pin J. two webs - first web 8 and second web 2 ·

Fig. 2 shows the webs 24® rotatably mounted with an adjustable position angle 10 with pin 11 on which the cutting mechanism is rotatably mounted.

The cutting mechanism is shown in Fig. 3. It consists of a rotatable cube 12 'which is mounted on the pin 11 and in which the fixture 13 for the linear movement with the hand drill 14 is fixed. 15 performs a linear movement when cutting. This movement is achieved with a hand drill

V coupled to the jig 13. The hand drill 14 together with the jig 13 are mounted in a rotatable cube 12 on which the fixed frame of the saw 12 together with the guide 16 of the saw 17 is provided. The guide 16 of the saw X7 can be either sliding or rolling and serves as a support for the saw 17.

The procedure for cutting with the cutting mechanism is as follows.

The cutting mechanism 18 is mounted on the cut plastic pipe 18 and fixed by means of a square prism 1 and a replaceable prism 6. This prism is pressed against the cut plastic pipe 18 and fastened by means of a screw 8 '.

Depending on the size of the pipe 18 to be cut, the respective exchangeable prism 6, whose dimensions vary according to the dimensions of the pipe 18 to be cut, is inserted into the screw 6 before use.

By pivoting the pin 11, a straight or oblique cut of the cut tube 18 can be made according to the selected setting, the pin 11 on which the cutting mechanism is rotatably supported is secured by a screw that is on the first web 8.

By actuating the hand drill 14, the saw 17 performs a linear movement and by rotating the cutting meohanism around the pin 11, the required portion of the cut pipe 18 is cut off at the desired angle. The saw speed 17 during cutting can be controlled by a thyristor regulator.

Cutting of plastic pipes by the plastic pipe cutting device according to the invention shown in FIG.

1, 2 and 3, in practice, the device according to the invention is fastened to the cut plastic pipe 18 by means of a square prism 1 and a replaceable prism 6 in a pipe dump, for example, and the cut plastic pipe 18 is cut off The saw performs a primocary movement with the help of the lowered hand drill ii and the jig for straight movement without further adjustment with any desired bevel, which allows the rotatably adjustable position of the angle bracket 10 carrying the cutting angle rotating on the pin to be performed. 11 of the bracket £ 0. ·
