Description

Technical Field

[0001] This utility model belongs to the field of hydraulic support hose cutting technology, specifically relating to a cutting device for hydraulic support hoses. Background Technology

[0002] Hydraulic support hoses are generally divided into steel wire braided hydraulic hoses and steel wire spiral hydraulic hoses. Hydraulic hoses are mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, 2, 4, or 6 layers of steel wire spiral reinforcement, and an outer rubber layer. The inner rubber layer has the function of bearing the pressure of the conveyed medium and protecting the steel wire from corrosion. The outer rubber layer protects the steel wire from damage. The steel wire layer is a skeleton material that plays a reinforcing role. However, the processing of hydraulic support hoses requires cutting.

[0003] Currently, existing hydraulic support hose cutting devices typically cut the hydraulic support hose by pressing down with a cutting blade. However, traditional hydraulic support hose cutting devices require operators to measure the length of the hydraulic support hose and mark the cutting position before cutting. This pre-cutting measurement method is often done manually. Although it can ensure the accuracy of the cutting position to a certain extent, the lack of a good reference when the hydraulic support hose is placed on the cutting device may reduce the accuracy, thus reducing the cutting precision of the hydraulic support hose. Utility Model Content

However, traditional hydraulic support hose cutting devices require operators to measure the length of the hydraulic support hose and mark the cutting position before cutting. This pre-cutting measurement method is often done manually. Although it can ensure the accuracy of the cutting position to a certain extent, the lack of a good reference when the hydraulic support hose is placed on the cutting device may reduce the accuracy, thus reducing the cutting precision of the hydraulic support hose.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4The present invention provides the following technical solution: a cutting device for hydraulic support hose, including a cutting seat 1, a first support 2 and a second support 3 connected to the top of the cutting seat 1, a first connecting plate 4 fixedly connected to the top of the first support 2, a second connecting plate 5 fixedly connected to the top of the second support 3, a lead screw 6 rotatably connected to the surface of the second connecting plate 5, and a threaded sleeve 7 threadedly connected to the outer wall of the lead screw 6.

[0024] A connecting block 8 is fixedly connected to the outer wall of the threaded sleeve 7. A mounting bracket 9 is fixedly connected to the bottom of the connecting block 8. A hydraulic cylinder 10 is installed on the inner side of the mounting bracket 9. A connecting bracket 11 is connected to the output end of the hydraulic cylinder 10. A cutting blade 12 is installed at the bottom of the connecting bracket 11. A laser positioner 13 is installed on the outer wall of the connecting bracket 11. A scale 14 is set on the top of the cutting seat 1. A mounting seat 15 is fixedly connected to the outer wall of the connecting bracket 11. A two-way screw 16 passes through one end of the mounting seat 15. Two threaded connecting blocks 17 are threadedly connected to the outer wall of the two-way screw 16. An arc-shaped clamping block 18 is fixedly connected to the outer wall of the two threaded connecting blocks 17.

[0025] It should be noted that a guide rod is fixedly connected between the first connecting plate 4 and the second connecting plate 5, and one end of the connecting block 8 is sleeved on the outer wall of the guide rod. A motor is installed on the surface of the first connecting plate 4, and the output end of the motor is connected to the lead screw 6, thereby driving the lead screw 6 to rotate.

[0026] Preferably, the top of the two threaded connecting blocks 17 is fixedly connected to a slider 19, and the top of the mounting base 15 is provided with a sliding groove 20. The two threaded connecting blocks 17 can form a sliding connection structure with the mounting base 15 through the slider 19 and the sliding groove 20. The through end of the bidirectional screw 16 forms a rotating connection structure with the inner wall of the mounting base 15 through a bearing.

[0027] In practical use, the laser positioner 13 is placed between two arc-shaped clamping blocks 18, and then the two-way lead screw 16 is rotated clockwise, so that the two threaded connecting blocks 17 connected to the outer wall can move towards each other along the slide groove 20 under the action of the slider 19. As the two threaded connecting blocks 17 move, the two arc-shaped clamping blocks 18 will move towards each other together, thereby fixing the laser positioner 13 on the outer wall of the connecting frame 11. Then, the laser positioner 13 is used to project a laser vertical line onto the cutting seat 1. By observing the position where the laser vertical line stops on the scale 14, the cutting position of the hydraulic support hose can be accurately located, thereby improving the cutting accuracy.

[0028] Preferably, a movable plate 21 is installed on the inner side of the first support 2, and a pressure block 22 is installed at the bottom of the movable plate 21. Grooves 23 are provided on the outer walls of both sides of the first support 2. A connecting rod 24 is fixedly connected inside the groove 23. A spring 25 is sleeved on the outer wall of the connecting rod 24. A movable block 26 is fixedly connected to the end of the movable plate 21. The end of the movable block 26 away from the movable plate 21 is sleeved on the outer wall of the connecting rod 24. The pressure block 22 can form an elastic structure with the first support 2 through the movable plate 21, the groove 23, the connecting rod 24, the spring 25, and the movable block 26.

[0029] It should be noted that the top of the cutting seat 1 has an arc-shaped groove for placing the hydraulic support hose, and the bottom of the pressure block 22 is arc-shaped.

[0030] In practical use, by pulling the handle upward on the movable plate 21, the movable block 26 at the end of the movable plate 21 will move along the outer wall of the connecting rod 24 and squeeze the spring 25. Then, the hydraulic support hose is placed in the arc-shaped groove at the top of the cutting seat 1. Finally, by releasing the handle, the pressure block 22 will be pressed down under the action of the spring 25, thereby achieving the clamping and fixing of the hydraulic support hose.

[0031] Working principle: First, by pulling the handle upwards on the movable plate 21, the movable block 26 at the end of the movable plate 21 will move along the outer wall of the connecting rod 24 and compress the spring 25. Then, the hydraulic support hose is placed in the arc-shaped groove at the top of the cutting seat 1. Finally, by releasing the handle, the pressure block 22 will be pressed down under the action of the spring 25, thereby clamping and fixing the hydraulic support hose. Then, the laser positioner 13 is placed between the two arc-shaped clamping blocks 18. Then, by rotating the double-acting screw 16 clockwise, the two threaded connecting blocks 17 with their outer wall threads can move towards each other along the slide groove 20 under the action of the slider 19. As the two threaded connecting blocks 17 move, the two arc-shaped clamping blocks 18 move towards each other along the slide groove 20. The clamping blocks 18 will move towards each other, thereby fixing the laser positioner 13 on the outer wall of the connecting frame 11. Then, the laser positioner 13 projects a vertical laser line onto the cutting seat 1. By observing the position of the vertical laser line on the scale 14, the cutting position of the hydraulic support hose can be accurately located, thereby improving the cutting accuracy. At this time, the motor drives the lead screw 6 to rotate, so that the threaded sleeve 7 connected to the outer wall can drive the connecting block 8 to move along the guide rod, thereby adjusting the position of the cutting blade 12. When the cutting blade 12 moves to the designated position, the hydraulic cylinder 10 drives the cutting blade 12 to press down, thereby cutting the hydraulic support hose in the arc groove at the top of the cutting seat 1.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
