Embodiment 1

[0033] Such as Figure 1~5 As shown, a metal hose anti-deformation cutting device of the present invention includes a cutting knife body, the cutting knife body is cylindrical, and the cutting knife body is divided into two parts A and B along the plane where the axis is located, and the A part is composed of four parts. The first cutting knife 2 is composed of four first cutting knives 2 arranged in sequence along the line where the axis of the cutting knife body is located, part B is a second cutting knife 3, the cross-sections of the first cutting knife 2 and the second cutting knife 3 are equal It is half of the cross-section of the cutter body, the axis of the first cutter 2 and the second cutter 3 coincide with the axis of the cutter body; the axes of the cutter body and the metal hose are parallel to each other, and the rotational speed of the cutter body It is 0.5N times the rotation speed of the metal hose, where N is a positive integer, and the cutter body only rotat...

Embodiment 2

[0035] An anti-deformation cutting device for metal hoses. On the basis of Embodiment 1, the straight lines where the four through holes 5 are located are on the cross-section of the placement box 13, and the straight lines where the four through holes 5 are located are two mutually perpendicular straight lines . The placement box 13 is provided with three groups of four through holes 5 , including a hollow cylinder formed by three groups of four connecting plates 7 . The length of the connecting rod 6 is greater than half of the thickness of the placement box 13 . Both the first cutting knife 2 and the second cutting knife 3 are connected with a sharp cutting piece 4 at one end, the cutting piece 4 is spirally distributed on the first cutting knife 2 and the second cutting knife 3, and the cutting piece 4 is connected with the metal soft When the pipe cutting surfaces are in contact, the angle between the cutting piece 4 and the horizontal plane is 30 degrees.

Embodiment 3

[0037] An anti-deformation cutting device for metal hoses, the two ends of metal hoses with a thickness of 50mm are placed in a placement box, the hollow part of the placement box 13 is a cylinder with a diameter of 200mm, and the length of the connecting rod 6 is 110mm. There are three groups of four through holes on the box, as well as the connecting rods and connecting plates on it, so three hollow cylinders are formed in total, and the metal hose is fixed in the three hollow cylinders on the same axis. The connecting plate 7 on the upper part is in contact with the side of the metal hose and clamped so that the metal hose and the storage box 13 rotate together. The groove 9 on the connecting plate 7 is circular, and the lower end of the connecting rod 6 is a corresponding circular shape. shape, so the lower end of the connecting rod 6 snaps into the groove 9, and can rotate in the groove 9 without falling out. When the connecting rod 6 rotates, the spring on the connecting ...

Abstract

The invention discloses an anti-deformation cutting device of a metal hose. The rotation speed of a cutter body is 0.5N times of the rotation speed of the metal hose, wherein N is a positive integer,and the cutter body only rotates one round; the two ends of the metal hose are placed into a cylindrical placing box with the middle part being hollow, the placing box is provided with four through holes, the through holes are in threaded connection with connection rods, the two ends of the connection rods are at outside of the through holes, the ends, in the placing box, of the connection rods are connected with connection plates, the connection plates on the four connection rods form a hollow cylinder, the connection rods rotate in the through holes to adjust the distance between the connection plates and the inner wall of the placing box, and the metal hose is fixed into the hollow cylinder composed of the four connection plates. The device can effectively relieve the stress when cutting the metal hose to prevent the metal hose from deforming in the cutting process, and thus the metal hose is more convenient to use for a long time.

Description

technical field [0001] The invention relates to the field of cutting, in particular to an anti-deformation cutting device for metal hoses. Background technique [0002] Metal hoses are important components in modern industry. The metal hose is made of 1Cr18Ni9Ti stainless steel as a whole, which has strong corrosion resistance. Metal hoses are used as wire and cable protection tubes for wires, cables, automated instrument signals, and civil shower hoses, with specifications ranging from 3mm to 150mm. There are many hose connectors for metal hoses, which are easy to connect with instruments and equipment. In actual use, it is necessary to cut and use the metal hose according to the actual situation, which involves the cutting of the metal hose. In the process, it is easy to cause the deformation of the cut, and the metal material makes it difficult to restore the deformed cut to the original structure. Therefore, the existing technology brings about the deformation of the ...
