Abstract

The utility model discloses a line drawing tool for U-shaped tube deep-hole welding cutting. The line drawing tool comprises a horizontal clamping plate. The horizontal clamping plate is fixedly provided with a circular-ring sleeve capable of being arranged on a U-shaped tube in a sleeved mode. A groove-shaped sliding block is further movably arranged on the horizontal clamping plate and can slide back and forth on the horizontal clamping plate. A semi-circular-ring clamping ring capable of being arranged on the U-shaped tube in a sleeved mode is fixedly arranged on the groove-shaped sliding block. The circular-ring sleeve and the semi-circular-ring clamping ring are respectively and simultaneously arranged on two tube end portions of the U-shaped tube in a sleeved mode. The upper end plane and the lower end plane of the circular-ring sleeve are respectively aligned with the upper end plane and the lower end plane of the semi-circular-ring clamping ring. The line drawing tool has the advantages of being simple and practical in structure, bringing great convenience to cutting of the U-shaped tube, and being capable of ensuring that the two ends of the cut U-shaped tube are located on the same horizontal plane.

Description

The scribing tooling that U-shaped pipe Deep Hole Welding cuts

Technical field

The utility model relates to the field that cuts of U-shaped pipe in heat exchanger.

Background technology

Before U-shaped pipe carries out Deep Hole Welding, need to cut the pipe end of U-shaped pipe, to meet the installation requirement of U-shaped pipe in heat exchanger shell, the two ends of the U-shaped pipe after cutting need to guarantee in same level, and at present U-shaped pipe is cut, be by tape measure, cannot effectively guarantee that the two ends of the U-shaped pipe after cutting are in same level.

Utility model content

The purpose of this utility model is: the scribing tooling that the U-shaped pipe Deep Hole Welding of the two ends that a kind of U-shaped pipe after effectively guaranteeing to cut is provided in same level cuts.

For achieving the above object, the technical solution adopted in the utility model is: the scribing tooling that U-shaped pipe Deep Hole Welding cuts, it is characterized in that: comprise horizontal clamp, on horizontal clamp, be installed with the annulus sleeve that can be enclosed within on U-shaped pipe, on horizontal clamp, be also movably installed with groove type slide block, groove type slide block can return slip on horizontal clamp, on groove type slide block, be installed with the semicircular ring snap ring that can be enclosed within on U-shaped pipe, described annulus sleeve and semicircular ring snap ring can be sleeved on respectively on two pipe end positions of U-shaped pipe simultaneously, and the upper transverse plane of annulus sleeve and lower transverse plane flush with upper transverse plane and the lower transverse plane of semicircular ring snap ring respectively.

Further, the scribing tooling that aforesaid U-shaped pipe Deep Hole Welding cuts, wherein, the inner diameter of annulus sleeve and semicircular ring snap ring is all than the large 0.2～0.3mm of the outer diameter of U-shaped pipe.

The utility model has the advantages that: simple and practical, by annulus sleeve and semicircular ring snap ring are sleeved on two pipe end positions of U-shaped pipe, and make the upper transverse plane of annulus sleeve and semicircular ring snap ring or lower transverse plane be positioned at the position that need to cut, marking is made at the position that so just can need to cut at U-shaped pipe, thereby greatly facilitate cutting of U-shaped pipe, and the two ends of the U-shaped pipe after guaranteeing to cut are in same level.

Accompanying drawing explanation

Fig. 1 is the scribing tooling structural representation that U-shaped pipe Deep Hole Welding described in the utility model cuts.

Fig. 2 is the structural representation that Fig. 1 overlooks direction.

Fig. 3 is the A-A cross-sectional view of Fig. 1 concave flute profile slide block.

The specific embodiment

Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail.

As Fig. 1, Fig. 2, shown in Fig. 3, the scribing tooling that U-shaped pipe Deep Hole Welding cuts, comprise horizontal clamp 1, on horizontal clamp 1, fixed installation can be sleeved on the annulus sleeve 2 on U-shaped pipe, on horizontal clamp 1, also active card is equipped with groove type slide block 3, groove type slide block 3 can slidably reciprocate on horizontal clamp 1, on groove type slide block 3, be installed with the semicircular ring snap ring 4 that can be sleeved on U-shaped pipe, described annulus sleeve 2 and semicircular ring snap ring 4 can be sleeved on respectively on the position, both ends of U-shaped pipe simultaneously, and the upper transverse plane of annulus sleeve 2 and lower transverse plane flush with upper transverse plane and the lower transverse plane of semicircular ring snap ring 4 respectively.In the present embodiment, the inner diameter of annulus sleeve 2 and semicircular ring snap ring 4 is all than the large 0.2～0.3mm of the outer diameter of U-shaped pipe.

During use, annulus sleeve 2 and semicircular ring snap ring 4 are set on two pipe end positions of U-shaped pipe, by the upper transverse plane of annulus sleeve 2 and semicircular ring snap ring 4 or lower end planar movement to position that U-shaped pipe will cut off, and in this position around annulus sleeve 2 and semicircular ring snap ring 4 marking line on U-shaped pipe, after painting, scribing tooling is removed, according to the mark line on U-shaped pipe, U-shaped pipe is cut, so just can guarantee that the two ends of the U-shaped pipe after cutting are in same level.Because groove type slide block 3 can move around on horizontal clamp 1, therefore can come the position of adjusting grooves shape slide block 3 on horizontal clamp 1 according to the spacing between two pipe ends of U-shaped pipe.

Claims

The scribing tooling that 1.U shape pipe Deep Hole Welding cuts, it is characterized in that: comprise horizontal clamp, on horizontal clamp, be installed with the annulus sleeve that can be enclosed within on U-shaped pipe, on horizontal clamp, be also movably installed with groove type slide block, groove type slide block can return slip on horizontal clamp, on groove type slide block, be installed with the semicircular ring snap ring that can be enclosed within on U-shaped pipe, described annulus sleeve and semicircular ring snap ring can be sleeved on respectively on two pipe end positions of U-shaped pipe simultaneously, and the upper transverse plane of annulus sleeve and lower transverse plane flush with upper transverse plane and the lower transverse plane of semicircular ring snap ring respectively.
2. the scribing tooling that U-shaped pipe Deep Hole Welding according to claim 1 cuts, is characterized in that: the inner diameter of annulus sleeve and semicircular ring snap ring is all than the large 0.2～0.3mm of the outer diameter of U-shaped pipe.
