Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a tool used for cutting a long hose. Background Art

[0002] At present, when cutting metal pipes, a cutting machine is generally used for operation. When the cutting machine cuts a long hose made of metal, the long hose is prone to deformation. Due to the thermal stress or mechanical stress generated during the cutting process, the hose may bend in a certain direction. This bending deformation may be slight or significant. Among them, the slight deformation near the cutting area, such as depressions, bulges or wrinkles, may be caused by the friction between the cutting tool and the hose surface, vibration during the cutting process, or improper setting of the cutting parameters, which causes the diameter of the long hose to change. For this reason, in some scenarios, long hoses need to be socketed with long hoses. If the deformed long hoses are to be socketed, they need to be corrected. According to the deformation of the hose, select appropriate special tools for correction, such as supporting the inside of the pipe body to restore the end of the long hose.

[0003] Based on the above, when the long hose is cut, the end of the long hose is prone to deformation. If the deformed long hose is to be restored, additional operations are required. For this reason, the long hose needs to be prevented from deformation during the cutting process. Generally, the inside of the long hose is supported to prevent it from deformation. However, due to the cutting position and the length of the long hose, it is difficult to completely support the support inside the long hose. Based on the above reasons, improvements are proposed.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 The present invention provides a technical solution: when a cutting machine cuts a long hose, a cutting speed that is too fast may result in incomplete cutting or a change in diameter, while a cutting speed that is too slow may result in low cutting efficiency or overheating. The cutting blade is generally sharp and has no obvious wear, but applying pressure to the long hose will easily cause the end of the long hose to deform. Therefore, the long hose needs to be processed again after cutting. Based on this, a tool for cutting long hoses is proposed, including a frame plate 1 and a frame plate 2 that are hingedly connected. The frame plate 1 and the frame plate 2 have an arc-shaped opening 3 on opposite sides for the long hose to pass through. The two frames are connected to the frame plate 1 and the frame plate 2. The arc-shaped opening 3 is in a circular shape. A cutting component 5 for cutting a long hose is provided on one side of the frame plate 1 and the frame plate 2. The cutting components 5 are provided with a plurality of circumferentially distributed ones. A driving unit 4 is installed on the other side of the frame plate 1 and the frame plate 2. The driving unit 4 is used to drive the plurality of cutting components 5 to rotate. The plurality of cutting components 5 and the driving unit 4 can be opened and closed with the frame plate 1 and the frame plate 2. The long hose can be directly put in by opening and closing the frame plate 1 and the frame plate 2, avoiding the long hose from being sleeved from the end, and avoiding the long hose or the cutting tool from being moved over a long distance.

[0030] Several cutting parts 5 have cutting blades 58 for cutting, and the outer sides of several cutting blades 58 are sleeved with support belts 6, which are used to realize the self-rotation of cutting blades 58. The outer sides of frame plate 1 and frame plate 2 are also provided with adjustment units 7 for controlling the tightness of support belts 6. Multiple cutting blades 58 are distributed along the outer wall of the long hose, so that the long hose is supported at multiple positions, and the cutting force can be distributed more evenly. During the cutting process, multiple cutting blades 58 act simultaneously to reduce the damage to the internal structure of the tube body. If single-point cutting is used, it may cause greater impact and extrusion to the internal structure of the long hose, while multi-point cutting can separate the material more gently and protect the inside of the long hose from damage.

[0031] The driving part 4 includes two halves of a semicircular cover 41 respectively fixed to the frame plate 1 and the frame plate 2, a sheet metal layer 43 is integrally formed on the inner side of the semicircular cover 41, and a sheet metal layer 42 is integrally formed on the outer side of the frame plate 1 and the frame plate 2, a transmission gear sleeve 44 is sandwiched between the sheet metal layer 1 42 and the sheet metal layer 2 43, and the transmission gear sleeve 44 is also arranged in two halves, and the two halves of the transmission gear sleeve 44 cooperate with each other and can rotate, dividing the entire transmission gear sleeve 44 into two, and are limited between the sheet metal layer 1 42 and the sheet metal layer 2 43. When separated, the two halves of the transmission gear sleeve 44 cooperate with the two halves of the semicircular cover 41, so that the frame plate 1 and the frame plate 2 can be opened, so that the long hose can be directly placed in for cutting. In addition, when the limited transmission gear sleeve 44 is driven to rotate by the driving gear 46, it can rotate as a whole;

[0032] A fixing plate 45 is fixed on the inner wall of the two halves of the transmission gear sleeve 44 , and the cutting component 5 is installed on the inner side of the fixing plate 45 so that the cutting component 5 can rotate with the fixing plate 45 and the transmission gear sleeve 44 .

[0033] The axes of the two halves of the transmission gear sleeve 44 and the two halves of the matching arc-shaped opening 3 coincide with each other, and the two halves of the transmission gear sleeve 44 are filled with lubricating oil to make the rotation process smooth and avoid jamming.

[0034] A driving gear 46 is rotatably provided on the outer side of the frame plate 2, and the driving gear 46 meshes with the transmission gear sleeve 44. A motor 47 is fixed on the outer side of the semicircular cover 41, and the output end of the motor 47 is connected to the driving gear 46. The motor 47 is used to drive the cutting action.

[0035] The cutting component 5 includes a metal plate 51 fixed to the inner side of the fixed plate 45, a sleeve 52 is fixed to the outer end of the metal plate 51, the sleeve 52 points to the axis of the fixed plate 45, a fastener 53 is slidably installed on the sleeve 52, and a rotating shaft 56 is rotatably installed on the outer side of the fastener 53. The cutting blade 58 is fixedly sleeved on the rotating shaft 56, and a circle of grooves 57 are provided on the outer wall of the rotating shaft 56. The support belt 6 is clamped in the groove 57. The support belt 6 and the groove 57 are both roughly designed. When the cutting component 5 rotates, the rotating shaft 56 rotates. It should be noted that the fastener 53 can slide along the sleeve 52, thereby changing the diameter clamped by the cutting blade 58, which is convenient for cutting long hoses of different diameters. In addition, the support belt 6 clamped in the groove 57 can avoid position deviation.

[0036] Support ends 54 are extended from the outer sides of the kit 52 and the fastener 53, and a support spring 55 is fixed between the two support ends 54. The support spring 55 acts as a reaction force, so that the fastener 53 has the force to move outward, ensuring the compression of the slot 57 and the support belt 6, and the squeezing force between the cutting blade 58 and the long hose can be adjusted by adjusting the tightness of the support belt 6.

[0037] The adjusting unit 7 includes an adjusting plate 71 fixed to the outer side of the frame plate 2. The adjusting plate 71 is arranged horizontally and has a horizontally arranged slide groove 72 on its outer side. A slider 73 is slidably arranged in the slide groove 72. The slider 73 has a gap for clamping the support belt 6. A cylinder 75 whose output end is fixed to the slider 73 is fixed to the inner side of the adjusting plate 71. The cylinder 75 is used to adjust the position of the slider 73. Two support shafts 74 for clamping the support belt 6 are also fixed on the adjusting plate 71. The support belt 6 passes through the two support shafts 74 and is then clamped on the slider 73. The cylinder 75 is used to pull the support belt 6 so that the tightness of the support belt 6 can be adjusted, and the support belt 6 passes between the two support shafts 74 so that the support belt 6 can rotate in a circular shape to the greatest extent. Even if the local position is not squeezed with the clamping groove 57, the cutting position can be adjusted by rotating the position of the long hose. It should be noted that the gap on the slider 73 for clamping the support belt 6 is V-shaped to clamp the support belt 6.

[0038] The outer arc surface of the cutting blade 58 is roughened to achieve friction through self-rotation. In addition, it is not blade-shaped to avoid excessive squeezing pressure at a single point and prevent the cutting blade 58 from squeezing marks on the long hose.

[0039] Working principle of the present invention: Due to the relatively long length of the long hose, it is not practical to sleeve the cutting tool from the end of the long hose, and the distance required to move is too large. Therefore, it can be split and opened through the frame plate 1 and the frame plate 2. During the opening process, the support belt 6 needs to be disassembled, and the support belt 6 needs to be sleeved from the end of the long hose. The frame plate 1 and the frame plate 2 are opened, and the two semicircular covers 41 and the two transmission gear sleeves 44 are separated. A plurality of cutting components 5 are separated, and the long hose is clamped in the arc-shaped opening 3. Then the frame plate 1 and the frame plate 2 cooperate, and the arc-shaped opening 3 is merged into one. The cutting blades 58 of the circular cutting components 5 are squeezed with the long hose under the action of the supporting spring 55. Under the driving action of the motor 47, the cutting components 5 are rotated. In addition, due to the squeezing of the card slot 57 and the non-rotating supporting belt 6, the cutting components 5 are rotated along the axis of the long hose, and the cutting blade 58 realizes self-rotation. The cutting blade 58 rotates while revolving along the long hose, so that the cutting blade 58 cuts the part of the circumference of the long hose that needs to be cut, so that the long hose can be effectively cut, which also helps to disperse the heat and stress generated during cutting and reduce the possibility of deformation of the long hose.

[0040] Among them, the expansion and contraction of the cylinder 75 is used to control the squeezing of the support belt 6 and the slot 57, and also drives the cutting blade 58 to move toward the axis of the long hose, so that the cutting blade 58 is squeezed against the outer wall of the long hose, and the support spring 55 provides a reverse supporting force, so even if the cutting blade 58 does not contact the outer wall of the long hose, the support belt 6 and the slot 57 are squeezed. For this reason, the expansion and contraction of the cylinder 75 is controlled to control the squeezing degree of the cutting blade 58 and the outer wall of the long hose, so as to avoid excessive squeezing force between the cutting blade 58 and the long hose and deformation of the long hose, so that the cutting blade 58 grinds and breaks the long hose during the process of revolution and rotation, thereby ensuring the accuracy of the long hose. In addition, even long hoses with different diameters can be cut and deformation of the cross section can be avoided.
