Pipe Cut Length Measurer {MEASURE OF LENGTH FOR AMPUTATION LENGTH PIPE}

The present invention relates to a pipe cutting length measurer, and more particularly, to measure the cutting length of a pipe to be cut with a pipe cutter, and at the same time, a pipe cutting length measurer configured to facilitate the pipe cutting operation by supporting and fixing the pipe to be cut. It is about.

In general, in the case of cutting a pipe with a pipe cutter outdoors, the length of the pipe to be cut is measured by a tape measure, and then the length of the pipe cut measured by a tape measure is measured on the pipe by using chalk, ink line or punching or nail. After the marking, the pipe was cut by cutting the marked portion with the cutting edge of the pipe cutter.

However, when cutting such a pipe, the cutting part of the pipe is gradually pushed and rotated by the cutting edge of the rotating pipe cutter, so that the end surface of the pipe is cut at an angle not to be constantly orthogonal to the cutting edge. Got this

In addition, in the case of cutting a plurality of pipes, when cutting the pipe marked with the cutting edge after marking the cutting length on the pipe by using a tape measure, the process of displaying the cutting length of the pipe and the cutting part of the marked pipe on the cutting edge Since the cutting length of the desired pipe is different in the matching process, not only do not cut a large number of pipes at the same length, but also the cutting work of the pipe takes a long time.

The present invention has been proposed in view of the above problems, and an object thereof is to provide a pipe cut length measurer configured to support and fix a pipe to be cut while simultaneously measuring the cut length of the pipe.

According to a feature of the present invention, at least one or more grid lines are formed in a predetermined lengthwise direction on an upper surface of a transverse guide bar, the front end of which is detachably coupled to a pedestal side of a pipe cutter by a coupling means, and the side of the transverse guide bar. It includes a cutting length measuring guide rail rotatably coupled to the pipe anti-rotation piece for supporting the outer peripheral surface of the pipe to be cut; A longitudinal guide bar having a predetermined length is coupled to be orthogonal to the transverse guide bar at an upper end of the transverse slide body which is coupled to be transported along the transverse guide bar of the cutting length measuring guide rail, and the longitudinal slide bar is transportably coupled to the longitudinal guide bar. The longitudinal slide body is coupled to the pipe support piece for supporting the pipe so that the support bar provided at the distal end can be transferred in a direction orthogonal to the longitudinal guide bar, the side of the horizontal slide body to unlock the horizontal slide body to be transported Transverse slide body fastener is coupled, the upper surface of the longitudinal slide body is characterized in that the longitudinal slide body and the support bar fasteners to lock the longitudinal slide body and the support bar to be released, respectively, the cutting length setting means combined A length measurer is provided.

When fixed, the pipe 40 is ready for cutting.

Then, when the cutting edge 30 of the pipe cutter 10 to be rotated about the rotating shaft 50, the pipe 40 is cut by the rotating cutting edge 30 to repeatedly pipe as desired length ( 40) can be cut.

In addition, the fine length adjusting means 290 along the guide hole 291 to the tolerance control bar as much as the thickness of the cutting edge 30 for cutting the pipe 40 depending on whether the pipe 40 is cut or discarded. After the transfer in the forward and backward direction to adjust the tolerance of the cutting length of the pipe 40 as much as the thickness of the cutting edge 30 to make a more precise and convenient pipe 40 cutting operation can be made.

In addition, in some cases, the pipe cutting machine by rotating the pipe anti-rotation piece 140 coupled to the hinge 141 rotatably on the side of the lateral guide bar 110 to be positioned higher than the upper surface of the lateral guide bar 110. The pipe 40 cut by 10 is prevented from being thrown off by the rotational force of the cutting edge 30 after cutting.

As described above, the pipe cut length measurer of the present invention measures the length of the pipe to be zero-pointed and cut by the horizontal slide body of the cutting length setting means, which is conveyed along the horizontal guide bar of the cutting length measuring guide rail. The pipe is cut by a pipe cutter while the pipe is measured and fixed so that the pipe whose length is measured by the pipe support piece and the pipe anti-rotation piece of the cutting length setting means can be easily cut to a certain length. There is an effect to improve the efficiency of.

In addition, by transferring the tolerance control bar of the fine length control means coupled to the lateral slide body to be slidable so that the measuring length of the pipe according to the cutting edge thickness of the pipe cutter is added and subtracted, horizontal using the horizontal gauge and height adjusting means By maintaining the state, there is an effect that the cutting of the pipe is more accurate.
