[0002] Hydraulic hoses, also known as hydraulic tubing, hydraulic hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure pipes, steel wire braided hoses, and steel wire wound hoses, are generally divided into steel wire braided hydraulic hoses and steel wire wound hydraulic hoses. After the production of hydraulic hoses is completed, it is necessary to crimp on the pipe fittings. Before crimping the pipe fittings, it is necessary to cut and strip the rubber of the hydraulic hoses.

Specific Embodiment

[0028] The present invention will be described in detail below with reference to the accompanying drawings and embodiments:

[0029] Please refer to Figures 1-8 , the hydraulic hose cutting device described in the present utility model includes a box body 1. A strip-shaped groove 2 is opened on the upper end surface of the box body 1 in the left-right direction. Two movable plates 3 are arranged in the strip-shaped groove 2. The outer end of each movable plate 3 is hinged to the box body 1. A gap 4 is provided between the inner ends of the two movable plates 3. A cutting piece 5 is rotatably arranged in the box body 1 and a motor 6 is fixedly arranged. The output shaft of the motor 6 is fixedly arranged with the rotating shaft 7 of the cutting piece 5. The cutting piece 5 is located in the gap 4 between the inner ends of the two movable plates 3. A torsion spring 8 is also arranged at the position where each movable plate 3 is hinged to the box body 1. The torsion spring 8 drives the inner ends of the two movable plates 3 to always move upward. Two limiting devices 9 for preventing the movable plates 3 from rotating upward are also arranged on the upper end surface of the box body 1. When the two movable plates 3 are driven by the torsion spring 8 to rotate upward and are blocked by the limiting devices 9, the upper end surfaces of the two movable plates 3 are flush with the upper end surface of the box body 1. A pressing mechanism 10 is also arranged on the upper end surface of the box body 1. The pressing mechanism 10 is used to press the hydraulic hose placed on the upper end surfaces of the two movable plates 3 so that the cutting piece 5 cuts the hydraulic hose.

[0030] During use, place the hydraulic hose on the upper end surfaces of the two movable plates 3, with both ends of the hydraulic hose located on the two limiting devices 9 respectively. Then, use the pressing mechanism 10 to press down on the hydraulic hose, causing the middle section of the hydraulic hose to bend downward, forcing the inner ends of the two movable plates 3 to rotate downward, and further causing the middle section of the hydraulic hose to contact the rotating cutting blade 5 to achieve cutting. The cut debris falls into the box body 1 between the inner ends of the two movable plates 3. At the same time, the pressing mechanism 10 functions to block the cut debris and prevent the debris from splashing.

[0031] In this embodiment, a housing 11 is fixedly arranged on the upper end surface of the box body 1. The pressing mechanism 10 includes a pressing rod 12 slidably arranged on the housing 11 in the vertical direction. The front end of the pressing rod 12 is located above the movable plate 3. One end of the pressing rod 12 located inside the housing 11 is connected to a driving device, and the driving device is used to drive the pressing rod 12 to move downward to achieve the purpose of pressing down on the hydraulic hose by the pressing rod 12.

[0032] In order to enable the lower end surface of the pressing rod 12 to function as blocking the splashing of debris, in this embodiment, a receiving groove 13 is formed in the lower end surface of the pressing rod 12 in the front-rear direction. During use, press the middle section of the hydraulic hose downward by the pressing rod 12 to cause the cutting blade 5 to cut the hydraulic hose. When the hydraulic hose is completely cut off, the cutting blade 5 will enter the receiving groove 13 of the pressing rod 12. At the same time, during the cutting process, part of the generated debris splashes into the receiving groove 13 and then falls into the box body 1 between the inner ends of the two movable plates 3, enabling the pressing rod 12 to effectively block the splashing of debris.

[0033] In order to achieve the function of cleaning the debris on the upper end surface of the box body 1 while the pressure rod 12 moves downward, in this embodiment, a cleaning rod 14 is slidably arranged on the upper end surface of the box body 1 in the front-rear direction. Two guide rods 15 are fixedly arranged on the rear side surface of the cleaning rod 14. A guide block 16 is fixedly arranged between the rear ends of the two guide rods 15 located inside the housing 11. An inclined surface is provided on the upper end surface of the guide block 16. The guide block 16 is slidably arranged in a through hole 17 opened on the rear side surface of the box body 1 in the front-rear direction. A support plate 18 is fixedly arranged on the rear side surface of the box body 1. The upper end surface of the support plate 18 is flush with the inner bottom wall of the through hole 17 of the box body 1. A vertical plate 19 is fixedly arranged on the upper end surface of the support plate 18. A first return spring 20 is fixedly arranged between the vertical plate 19 and the guide block 16; when the pressure rod 12 moves downward, the rear end of the pressure rod 12 contacts the inclined surface of the guide block 16, forcing the guide block 16 to move backward to compress the first return spring 20, and further causing the guide block 16 to drive the cleaning rod 14 to move backward on the upper end surface of the box body 1 through the two guide rods 15, so that the cleaning rod 14 scrapes the debris on the upper end surface of the box body 1 and pushes it into the strip-shaped groove 2 of the box body 1. Since the pressure rod 12 simultaneously presses the hydraulic hose downward, the inner ends of the two movable plates 3 have rotated downward at this time to connect the strip-shaped groove 2 with the inside of the box body 1. Therefore, the debris pushed into the strip-shaped groove 2 by the cleaning rod 14 falls into the box body 1 from the strip-shaped groove 2. After the hydraulic hose is cut, the driving device drives the pressure rod 12 to move upward, and the first return spring 20 pushes the guide block 16 to move forward, and further causes the guide block 16 to drive the cleaning rod 14 to move forward through the guide rod 15, so that the cleaning rod 14 is reset; the setting of the support plate 18 is to extend the backward movement distance of the guide block 16.

[0034] In order to achieve the purpose of driving the pressure rod 12 to move downward, in this embodiment, the driving device includes two hinged connecting rods 21. The outer ends of the two connecting rods 21 are respectively hinged to the inner bottom wall of the housing 11 and the upper end surface of the pressure rod 12. The top end of the upper connecting rod 21 is fixedly provided with a hinge shaft 22 hinged to the housing 11. The right end of the hinge shaft 22 extends to the right side of the housing 11 and is provided with a driving rod 23; by manually rotating the driving rod 23, the driving rod 23 rotates downward to drive the hinge shaft 22 to rotate, so that the hinge shaft 22 drives the bottom end of the upper connecting rod 21 to rotate, and further drives the lower connecting rod 21 to rotate. When the two connecting rods 21 tend to rotate into a vertical line, the pressure rod 12 is pushed downward; when the angle between the ends of the two connecting rods 21 hinged to each other becomes smaller and smaller, the pressure rod 12 is driven upward.

[0035] In order to achieve the purpose that the cleaning rod 14 is limited in position when moving forward, in this embodiment, the pressing rod 12 is slidably arranged in the vertical hole 24 opened on the front side of the housing 11. The inner top wall of the vertical hole 24 limits the upward movement distance of the pressing rod 12, thereby enabling the rear end of the pressing rod 12 to limit the forward movement distance of the guiding block 16, and further enabling the guiding block 16 to limit the forward movement distance of the cleaning rod 14 through the two guide rods 15.

[0036] In order to achieve the purpose that the pressing rod 12 can automatically reset upward after moving downward, in this embodiment, a second return spring 25 is fixedly arranged between the left side surface of the upper connecting rod 21 and the inner bottom wall of the housing 11. When the pressing rod 12 moves downward, the two connecting rods 21 rotate towards the trend of being in a vertical line, causing the upper connecting rod 21 to stretch the second return spring 25 simultaneously. At this time, the second return spring 25 will generate a downward inclined movement. When the driving rod 23 is manually rotated to make the pressing rod 12 move downward and then the driving rod 23 is released, at this time, the second return spring 25 pulls the bottom end of the upper connecting rod 21 to rotate upward, enabling the pressing rod 12 to move upward until the upper end surface of the pressing rod 12 contacts the inner top wall of the vertical hole 24, achieving the purpose of the automatic upward reset of the pressing rod 12; when the pressing rod 12 moves upward and automatically resets, the first return spring 20 pushes the guiding block 16 to move forward, and further the guiding block 16 drives the cleaning rod 14 to move forward through the guide rod 15, simultaneously realizing the automatic reset of the forward movement of the cleaning rod 14, and the rear end of the pressing rod 12 limits the forward movement distance of the cleaning rod 14 through the guiding block 16.

[0037] In this embodiment, the limiting device 9 includes two limiting plate groups fixedly arranged on the upper end surface of the box body 1. The two limiting plate groups are respectively located above the left and right sides of the strip-shaped groove 2. The lower end surfaces of the two limiting plate groups are flush with the upper end surface of the box body 1. When the torsion spring 8 drives the inner ends of the two movable plates 3 to rotate upward, when the upper end surfaces of the two movable plates 3 contact the lower end surfaces of the limiting plate groups, the two movable plates 3 stop rotating, realizing the limitation of the two movable plates 3. In order to support both ends of the hydraulic hose, each limiting plate group is composed of two limiting plates 26 arranged front and back. A sleeve 27 is fixedly arranged between the two limiting plates 26 of each limiting plate group; each guide rod 15 is sleeved with the corresponding sleeve 27; during use, both ends of the hydraulic hose are respectively placed on the sleeves 27, and at the same time, the middle section of the hydraulic hose is located below the pressing rod 12. Then, manually push the driving rod 23 to rotate downward, so that the two connecting rods 21 drive the pressing rod 12 to move downward, pressing the middle section of the hydraulic hose, so that the cutting piece 5 cuts the middle section of the hydraulic hose. Part of the debris generated by the cutting falls into the box body 1, part of it splashes upward into the accommodating groove 13 of the pressing rod 12 and then falls into the box body 1, and part of it falls on the upper end surface of the box body 1. As the pressing rod 12 moves downward, the debris on the upper end surface of the box body 1 makes the pressing rod 12 drive the cleaning rod 14 to move backward through the guiding block 16 and the two guide rods 15 in sequence, so that the cleaning rod 14 scrapes the debris on the upper end surface of the box body 1 into the strip-shaped groove 2 of the box body 1 and falls into the interior of the box body 1, realizing the purpose of cleaning the upper end surface of the box body 1.

[0038] In this embodiment, in order to achieve the purpose of facilitating the fixation of the limiting plate 26 to the box body 1, in this embodiment, fixing plates 28 are fixedly arranged at the positions corresponding to each limiting plate 26 on the upper end surface of the box body 1; the outer ends of the two limiting plates 26 in each limiting plate group are respectively sleeved with the corresponding two fixing plates 28 through through bolts 29; both ends of each sleeve 27 extend outward and are respectively sleeved with the corresponding fixing plates 28; achieving the purpose of restricting the lower end surface of the limiting plate 26 to a position flush with the upper end surface of the box body 1 through the cooperation of the sleeve 27 and the through bolt 29 with the fixing plate 28.

[0039] In this embodiment, two side plates 30 are fixedly arranged on the inner top wall of the box body 1. The rotating shafts 7 are respectively rotatably connected to the front ends of the two side plates 30. The cutting piece 5 is fixedly arranged on the rotating shaft 7 located between the two side plates 30. One end of the rotating shaft 7 is fixedly arranged with the output shaft of the motor 6. When the motor 6 starts, the cutting piece 5 is driven to rotate through the rotating shaft 7.

[0040] Working principle of the utility model: During use, place the two ends of the hydraulic hose on the sleeve 27 respectively. At the same time, the middle section of the hydraulic hose is located below the pressure rod 12. Then manually push the driving rod 23 to rotate downward, so that the two connecting rods 21 drive the pressure rod 12 to move downward, compress the middle section of the hydraulic hose, and enable the cutting blade 5 to cut the middle section of the hydraulic hose. Part of the shredded materials generated by cutting fall into the box body 1, part fly upward into the accommodation groove 13 of the pressure rod 12 and then fall into the box body 1, and part fall onto the upper end surface of the box body 1. As the shredded materials falling onto the upper end surface of the box body 1 move downward with the pressure rod 12, the pressure rod 12 drives the cleaning rod 14 to move backward through the guiding block 16 and the two guide rods 15 in sequence, so that the cleaning rod 14 scrapes the shredded materials on the upper end surface of the box body 1 into the strip-shaped groove 2 of the box body 1 and falls into the interior of the box body 1. The shredded materials falling into the box body 1 are centrally processed to achieve the purpose of cleaning the upper end surface of the box body 1.
