Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic chain cutting, and specifically refers to a high-efficiency hydraulic chain cutter with a high-hardness alloy cutter head. Background Art

[0002] The working principle of the hydraulic chain cutter is to use hydraulic pressure to cut the chain. Specifically, it first generates high-pressure liquid through the hydraulic system, and then converts the liquid pressure into mechanical force through a specific hydraulic cylinder or piston mechanism. This mechanical force then acts on the high-hardness alloy cutter head to move and complete the chain cutting.

[0003] The existing hydraulic chain cutters have the following problems:

[0004] The existing hydraulic chain cutter does not have the function of cooling the hydraulic oil used in the long-term cutting operation, which causes the temperature of the hydraulic oil to rise during the long-term cutting operation, reduces the transmission performance of the hydraulic oil, and affects the cutting efficiency of the tool on the chain. In addition, the traditional cooling method for the hydraulic oil is mostly to cool the hydraulic oil stored in the container for a long time. With such a cooling method, on the one hand, overall cooling of the hydraulic oil wastes energy. On the other hand, long-term cooling of the hydraulic oil will accelerate its aging process. Therefore, it cannot meet the existing use requirements of the hydraulic chain cutter. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides a high-efficiency hydraulic chain cutter with a high-hardness alloy cutter head that has the ability to cool the hydraulic oil used in long-term shearing operations, ensure the transmission performance of the hydraulic oil, and cool the hydraulic oil involved in the driving operation.

[0006] The technical scheme adopted in this scheme is as follows: This scheme proposes a high-efficiency hydraulic chain cutter with a high-hardness alloy cutter head, including a chain cutting platform, a hydraulic cylinder, a base, a multi-channel liquid drive mechanism and a pressure zone type cooling mechanism. The hydraulic cylinder is symmetrically arranged on the side wall of one end of the chain cutting platform, and the base is arranged on the bottom wall of the hydraulic cylinder at one end away from the chain cutting platform. The multi-channel liquid drive mechanism is arranged on the upper wall of the chain cutting platform, and the pressure zone type cooling mechanism is arranged on the multi-channel liquid drive mechanism. The multi-channel liquid drive mechanism includes a liquid pushing mechanism, a shearing mechanism and an infusion mechanism. The liquid pushing mechanism is arranged on the upper wall of the chain cutting platform away from the hydraulic cylinder, the shearing mechanism is arranged on the liquid pushing mechanism, and the infusion mechanism is arranged on the upper wall of the hydraulic cylinder.

[0007] As a further preferred embodiment of the present invention, the hydraulic pushing mechanism includes a positioning platform, a hydraulic cylinder body and a piston rod.

[0008] When in use, in the initial state, the piston rod is retracted into the hydraulic cylinder body, the spacing between the high-hardness alloy cutter heads is the maximum distance, the chain to be sheared is placed between the high-hardness alloy cutter heads, and the hydraulic pump draws the hydraulic oil inside the hydraulic cylinder through the pumping end, and the hydraulic oil enters the liquid supply pipe through the oil supply end of the hydraulic pump. The hydraulic oil inside the liquid supply pipe enters the hydraulic cylinder body through the brass elbow and the one-way valve. The hydraulic oil inside the hydraulic cylinder body pushes the piston rod to move, and the piston rod drives the tool seat to slide along the guide plate, and the tool seat drives the high-hardness alloy cutter head to move relative to the chain and fit the chain. As the hydraulic oil inside the hydraulic cylinder body continues to enter, the pressure of the hydraulic oil inside the hydraulic cylinder body increases, and the hydraulic oil with a larger pressure pushes the piston rod through the tool seat to drive the high-hardness alloy cutter head to shear the chain.

[0009] Preferably, the outer sleeve mechanism includes a reinforced metal bent sleeve, a cooling port and a transparent thermal insulation bent sleeve, the reinforced metal bent sleeve is arranged on the outside of the brass bent pipe, multiple groups of cooling ports are arranged on the side wall of the reinforced metal bent sleeve, and the transparent thermal insulation bent sleeve is arranged on the outside of the reinforced metal bent sleeve; the cold source mechanism includes a cooling box, a thermoelectric refrigeration sheet group, a series copper rod, a cooling copper rod, a cold source temperature sensor and a thermal insulation valve, the cooling box is arranged through the inner wall of the positioning platform, multiple groups of thermoelectric refrigeration sheet groups are arranged through the side wall of the cooling box, the cooling end of the thermoelectric refrigeration sheet group is arranged inside the cooling box, the series copper rod is arranged through the transparent thermal insulation bent sleeve between one end close to the one-way valve, the thermal insulation valve is symmetrically arranged on both sides of the positioning platform, the thermal insulation valve is arranged through the positioning platform and is connected with the cooling box, the cooling copper rod is arranged through the insulation valve and the series copper rod, the outside of the series copper rod and the cooling copper rod are coated with a thermal insulation coating, the cold source temperature sensor is arranged on the side wall of the chain cutting platform, and the detection end of the cold source temperature sensor is arranged through the cooling box.

[0010] During use, the hydraulic oil temperature rises as the pressure inside the hydraulic cylinder increases. When the temperature of the hydraulic oil rises, its viscosity decreases, resulting in poor lubrication performance and thinner oil film, which increases friction and wear between mechanical parts, leading to a decrease in work efficiency. Long-term cooling of the hydraulic oil will accelerate its aging process. In a low temperature environment, the additives in the hydraulic oil will lose their activity or decompose, resulting in a decrease in oil performance. Therefore, it is necessary to continuously cool the hydraulic oil during the working process, and to avoid the accelerated aging of the hydraulic oil under long-term cooling. When the temperature of the hydraulic oil inside the hydraulic cylinder increases, the thermoelectric refrigeration plate group cools the air inside the cooling box through the refrigeration end, the cold source temperature sensor monitors the temperature inside the cooling box through the detection end, and the cooling box cools the series copper rods through the cooling copper rods, and the series copper rods cool the air inside the transparent thermal insulation bent sleeve. After the internal temperature of the transparent thermal insulation bent sleeve is reduced, the brass elbow is cooled through the cooling port. Since the brass elbow is close to the hydraulic cylinder, the hydraulic oil cooled inside the brass elbow can cool the hydraulic oil with a higher temperature inside the hydraulic cylinder, thereby ensuring the working temperature of the hydraulic oil.

[0011] Specifically, a controller is provided on the side wall of the chain cutting table on one side of the cold source temperature sensor.

[0012] Wherein, the controller is electrically connected to the proximity switch, the hydraulic pump, the thermoelectric cooling sheet group and the cold source temperature sensor respectively.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, this solution adopts a combination of a local temperature conduction structure and a local sleeve structure. Through the multi-channel liquid drive mechanism and the pressure zone cooling mechanism, the liquid pushing mechanism, the shearing mechanism, the liquid infusion mechanism, the outer sleeve mechanism and the cold source mechanism are used in coordination with each other. Under the condition of avoiding long-term cooling of the hydraulic oil inside the hydraulic cylinder, the hydraulic oil that is squeezed and the temperature rises during the operation can be cooled, the driving performance of the hydraulic oil can be guaranteed, the shearing efficiency of the high-hardness alloy cutter head on the chain can be improved, and under the protection of the reinforced metal bending sleeve, the brass elbow can not be deformed under a large pressure, ensuring the flow of hydraulic oil. Secondly, the cooling copper rod cools the hydraulic oil delivery pipeline locally, which can reduce the energy output of the cooling equipment and avoid overall cooling of a large amount of hydraulic oil, thereby reducing the energy consumption of the hydraulic chain cutter to a certain extent. The hydraulic oil temperature inside the hydraulic cylinder increases. At this time, the thermoelectric refrigeration plate group cools the air inside the cooling box through the refrigeration end, and the cold source temperature sensor monitors the temperature inside the cooling box through the detection end. The cooling box cools the series copper rods through the cooling copper rods, and the series copper rods cool the air inside the transparent thermal insulation bent sleeve. After the internal temperature of the transparent thermal insulation bent sleeve is reduced, the brass elbow is cooled through the cooling port. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The jacket mechanism 22 includes a reinforced metal curved sleeve 23, a cooling port 24 and a transparent heat-insulating curved sleeve 25. The reinforced metal curved sleeve 23 is arranged on the outside of the brass curved tube 19, and multiple groups of cooling ports 24 are arranged on the side wall of the reinforced metal curved sleeve 23.

[0033] A controller 33 is provided on the side wall of the chain cutting platform 1 on the side of the cold source temperature sensor 31 .

[0034] The controller 33 is electrically connected to the proximity switch 14 , the hydraulic pump 16 , the thermoelectric cooling sheet group 28 and the cold source temperature sensor 31 , respectively.

[0035] When in use, in the initial state, the piston rod 8 is retracted into the hydraulic cylinder body 7, the spacing between the high-hardness alloy cutter heads 12 is the maximum distance, hydraulic oil is injected into the hydraulic cylinder 2, and the liquid control valve 20 set on the outside of the liquid supply pipe 18 is closed. At this time, the hydraulic cylinder 2 and the hydraulic cylinder body 7 are blocked and cut off, and the insulation valves 32 on both sides of the positioning platform 6 are closed. According to the material and hardness of the chain to be sheared, the high-hardness alloy cutter head 12 is adjusted to perform unidirectional or bidirectional shearing of the chain;

[0036] When the chain material is relatively soft, the liquid control valve 20 provided on the outer side of the liquid supply pipe 18 at one end of the positioning platform 6 is opened. In order to prevent the brass elbow 19 from being subjected to a large pressure under continuous operation, an alternating operation method is adopted to reduce the probability of deformation of the brass elbow 19 and provide double protection for the brass elbow 19. The controller 33 controls the operation of the hydraulic pump 16 provided on the hydraulic cylinder 2 at one end of the chain cutting platform 1;

[0037] The chain to be sheared is placed on the side wall of the high-hardness alloy cutter head 12 at one end of the positioning platform 6 where the control valve 20 is not opened. The hydraulic pump 16 draws the hydraulic oil inside the hydraulic cylinder 2 through the pumping end. The hydraulic oil enters the liquid supply pipe 18 through the oil supply end of the hydraulic pump 16. The hydraulic oil inside the liquid supply pipe 18 enters the hydraulic cylinder body 7 through the brass elbow 19 and the one-way valve 17. The hydraulic oil inside the hydraulic cylinder body 7 pushes the piston rod 8 to move. The piston rod 8 drives the tool seat 11 to slide along the guide plate 10. The tool seat 11 drives the high-hardness alloy cutter head 12 at one end of the positioning platform 6 to move toward the high-hardness alloy cutter head 12 at the other end. The moving high-hardness alloy cutter head 12 fits with the chain. As the hydraulic oil inside the hydraulic cylinder body 7 The hydraulic oil in the hydraulic cylinder 7 is continuously entering, and the pressure of the hydraulic oil in the hydraulic cylinder 7 increases. The hydraulic oil with a relatively large pressure pushes the piston rod 8 to drive the high-hardness alloy cutter head 12 to shear the chain through the cutter seat 11, and the chain shearing is completed. The controller 33 controls the hydraulic pump 16 to pump the hydraulic oil in the hydraulic cylinder 7 back to the corresponding hydraulic cylinder 2. Then the controller 33 controls the hydraulic pump 16 arranged on the hydraulic cylinder 2 at the other end of the chain cutting platform 1 to operate, and the hydraulic pump 16 transports the hydraulic oil in the hydraulic cylinder 2 to the hydraulic cylinder 7. The hydraulic oil in the hydraulic cylinder 7 drives the cutter seat 11 to slide along the guide plate 10 through the piston rod 8, and the cutter seat 11 drives the high-hardness alloy cutter head 12 to shear the softer chain.

[0038] When the chain material is relatively hard, the liquid control valves 20 provided at both ends of the liquid supply pipe 18 are opened, and the chain to be sheared is placed between the high-hardness alloy cutter heads 12. The controller 33 controls the hydraulic pump 16 to start. The hydraulic pump 16 extracts the hydraulic oil inside the hydraulic cylinder 2 through the liquid extraction end, and the hydraulic oil is transported to the inside of the liquid supply pipe 18 through the liquid supply end of the hydraulic pump 16. The liquid supply pipe 18 transports the hydraulic oil to the inside of the hydraulic cylinder body 7 through the brass elbow 19. The brass elbow 19 transports the hydraulic oil under the protection of the reinforced metal elbow sleeve 23. The hydraulic oil pushes the piston rod 8 to drive the tool seat 11 to move relative to the guide plate 10. The tool seat 11 drives the high-hardness alloy cutter head 12 to move relative to the chain and fit the chain. As the hydraulic oil pressure inside the hydraulic cylinder body 7 increases, the chain with a relatively hard material can be sheared. The hydraulic pump 16 provided on the hydraulic cylinder 2 works alternately to complete the chain shearing operation.

[0039] When the pressure inside the hydraulic cylinder 7 increases, the temperature of the hydraulic oil increases accordingly. When the temperature of the hydraulic oil increases, its viscosity decreases, the lubrication performance deteriorates, and the oil film becomes thinner, thereby increasing the friction and wear between the mechanical parts, resulting in a decrease in working efficiency. In addition, cooling the hydraulic oil for a long time will accelerate its aging process. In a low temperature environment, the additives in the hydraulic oil will lose their activity or decompose, resulting in a decrease in the performance of the oil. Therefore, it is necessary to continuously cool the hydraulic oil during the working process, but also to avoid the hydraulic oil from being cooled for a long time to accelerate its aging process.

[0040] During the unidirectional shearing operation, the insulation valve 32 at one end of the positioning platform 6 close to the opened liquid supply pipe 18 is opened. During the bidirectional shearing operation, the insulation valves 32 on both sides of the positioning platform 6 are opened. The controller 33 controls the thermoelectric refrigeration sheet group 28 to start, and the thermoelectric refrigeration sheet group 28 cools the air inside the cooling box 27 through the refrigeration end. The controller 33 controls the cold source temperature sensor 31 to start, and the cold source temperature sensor 31 monitors the temperature inside the cooling box 27 through the detection end. The cooling box 27 cools the series copper rod 29 through the cooling copper rod 30, and the series copper rod 29 cools the air inside the transparent thermal insulation curved sleeve 25. After the internal temperature of the transparent thermal insulation curved sleeve 25 is reduced, the brass elbow 19 is cooled through the cooling port 24. Since the brass elbow 19 is arranged close to the hydraulic cylinder body 7, the hydraulic oil cooled inside the brass elbow 19 can cool the hydraulic oil with a higher temperature inside the hydraulic cylinder body 7, thereby ensuring the working temperature of the hydraulic oil and efficiently completing the shearing process of the chain; repeat the above operation when using it next time.

[0042] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
