Description

Technical area

The present invention relates to the field of metalware processing, in particular provided with cooling blades and fan clamping device for pipe cutter.

Technical background

In metalworking often steel pipes are cut, either for cutting, or to achieve a particular oblique cut surface. The steel pipes are held manually or by an auxiliary device. However, the performance of the conventional auxiliary devices still leaves something to be desired. The larger the diameter of the steel tubes, or the heavier they are, the harder it will be to hold them firmly. The cutting results suffer from this and also lead to problems with subsequent assembly or welding. There is therefore a need to develop a clamping device for pipe cutters, which reliably hold the steel pipes during cutting and can guarantee precise cutting results.

Content of the invention

The present invention is therefore based on the object to provide a clamping device that reliably hold the steel pipes when cutting and can guarantee precise cutting results.

This object is achieved by the following technical concept: The clamping device for tube cutter according to the invention provided with cooling blades and fan comprises an upper frame and a lower frame, between which stand columns are arranged. On the insides of the pedestals first guide grooves are arranged. Between the upper parts of the pedestals an upper clamping piece with a crooked contour is provided which is movably seated in the first guide grooves. On the back of the upper clamping piece a main shaft is mounted, which passes through the upper frame and has a head. In the upper frame, a cavity is provided, in which a shaft sleeve is arranged, which surrounds the main shaft. The shaft sleeve is connected at its center with a first gear, which is positively connected to its right side with a second gear. The second gear is connected at its upper end to a drive motor which is surrounded by cooling blades to cool the operating heat, wherein the cooling blades are still supported by a fan. The drive motor is firmly connected to the upper frame. Below the upper clamping piece lower clamping pieces are provided with curved contours. The pedestals have pedestals at the lower ends. The lower clamping pieces have at their sides facing the sockets each have a secondary shaft, which pass through the base and are connected at the outer ends in each case with a hand crank. On the surface of the lower frame, a second guide groove is arranged, in which the lower clamping pieces are movable.

Preferably, the curved contours of the upper clamping piece and the lower clamping pieces are provided with a non-slip layer.

Preferably, the number of lower clamping pieces is two.

embodiment

In the following an embodiment of the present invention will be explained in more detail with reference to the drawing.

As 1 shows the invention provided with cooling blades and fan clamping device for pipe cutter an upper frame 1 and a lower frame 14 between which standing pillars 10 are arranged. On the insides of the pillars 10 are first guide grooves 11 arranged. Between the upper parts of the pillars 10 is an upper clamping piece 9 provided with a crooked contour in the first guide grooves 11 sitting movably. On the back of the upper clamping piece is a main shaft 5 attached by the upper frame 1 passes through and a head 4 having. In the upper frame 1 is a cavity 8th provided in which a shaft sleeve 6 is arranged, which is the main shaft 5 surrounds. The shaft sleeve 6 is at its center with a first gear 7 connected to the right with a second gear 2 is positively connected. The second gear 2 is at its upper end with a drive motor 3 connected by cooling sheets 18 is surrounded to cool the operating heat, with the cooling blades 18 still from a fan 19 get supported. The drive motor 3 is with the upper frame 1 firmly connected. Below the upper clamping piece 9 are lower clamping pieces 15 provided with curved contours. The pillars 10 have sockets at the lower ends 12 on. The lower clamping pieces 15 point to their sockets 12 each side facing a secondary shaft 16 on that through the pedestal 12 lead through and at the outer ends each with a hand crank 17 are connected. On the surface of the lower frame 14 is a second guide groove 13 arranged in which the lower clamping pieces 15 sitting movably.

Preferably, the curved contours of the upper clamping piece 9 and the lower clamping pieces 15 provided with non-slip layer.

Preferably, the number of lower clamping pieces 15 two.

The present invention is not limited to the embodiment shown above. The embodiment shown above is illustrative only and has no limiting effect. Other embodiments that are identical or equivalent to the technical concept of the present invention are also covered by the claims of the present invention.
