Description

Technical Field

[0001] The invention relates to the field of hydraulic pipe cutting, and in particular to a hydraulic pipe cutting device and a use method thereof. Background Art

[0002] Hydraulic pipe is also known as hydraulic oil pipe, hydraulic hose, high-pressure hose, hydraulic hose, steel wire high-pressure hose, steel wire braided hose, and steel wire spiral hose. It is generally divided into steel wire braided hydraulic hose and steel wire spiral hydraulic hose. The hydraulic hose is mainly composed of liquid-resistant inner rubber layer, middle rubber layer and outer rubber layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion. The outer rubber layer protects the steel wire from damage. The steel wire layer is the skeleton material and plays a reinforcing role.

[0003] When cutting hydraulic pipe fittings, rubber hydraulic pipe fittings are prone to deformation, which may cause the hydraulic pipe fittings to deform when the cutting knife contacts them. If the hydraulic pipe fittings are compressed and deformed, the cutting position may deviate, and the deviation caused by the deformation may lead to cutting errors, affecting the cutting accuracy. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a hydraulic pipe cutting device and a method of using the same.

[0005] In a first aspect, the present invention provides a hydraulic pipe cutting device, comprising a processing table, and further comprising:

[0006] A first inner groove is provided through the interior of the processing table and is used for the pipe to pass through for cutting processing;

[0007] A second inner groove is provided inside the processing table;

[0008] A cutting assembly, installed inside the processing table, for cutting the pipe fittings;

[0009] A support assembly is suspended and installed inside the first inner groove by magnetic force, and is used to support the inner wall of the pipe that is cut through the first inner groove;

[0010] A conveying assembly is installed at both ends of the processing table and is used to drive the pipe to move so as to drive the pipe to move and adjust the cutting position;

[0011] The staff inserts the pipe to be cut into the first inner groove. When inserting, the support assembly suspended in the first inner groove passes through the inside of the pipe, so that the support assembly supports the inside of the pipe. When the pipe is cut, the pipe is supported by the support assembly, so that the pipe will not be greatly deformed when it is cut and squeezed, which is conducive to avoiding the situation where the pipe is deformed during cutting and the cutting accuracy is affected. At the same time, due to the suspended setting of the support assembly, the existence of the support assembly will not affect the pipe passing through the first inner groove, so that any length of the pipe can pass through the inside of the first inner groove and be supported by the support assembly, which is convenient for cutting pipes of any length.

[0012] Then the staff starts the cutting assembly, and the pipe fittings are cut after the cutting assembly is started, thereby realizing the cutting process of the pipe fittings;

[0013] When cutting the pipe fittings, the staff starts the conveying component, which drives the pipe fittings to move after starting, thereby driving the pipe fittings themselves to move, so that the pipe fittings can adjust their moving positions through their own movement, which is conducive to adjusting the cutting position according to the required cutting size.

[0014] Preferably, the support assembly comprises:

[0015] Two support tubes are symmetrically arranged inside the first inner tank;

[0016] Two first magnets are respectively fixed inside the mounting grooves opened at opposite ends of the two support tubes;

[0017] Two groups of second magnets, two of which form a group, are symmetrically mounted at both ends of the processing table, and the second magnets in the same group are symmetrically fixed and embedded in the interior of the processing table, and the upper and lower ends of the first magnet are respectively arranged opposite to the same magnetic poles of the two second magnets in the same group;

[0018] A group of second magnets corresponds to a first magnet, and the upper part of the first magnet faces the same magnetic pole as the upper second magnet, and the lower part of the first magnet faces the same magnetic pole as the lower second magnet, so that the two second magnets support the first magnet in mid-air through magnetic repulsion, thereby forming a suspended support for the support tube. The two groups of second magnets form a suspended support for the two support tubes, and the opposite ends of the two support tubes are aligned with the cutting assembly, so that the cutting assembly can push the two support tubes apart when cutting the pipe fitting, which is beneficial to avoid the situation where the support of the support tube hinders the cutting of the pipe fitting.

[0019] Preferably, the cutting assembly comprises:

[0020] A turning frame, rotatably mounted inside the second inner groove;

[0021] A cutting knife is rotatably mounted on the end of the turning frame;

[0022] A first motor, fixed inside the processing table, is used to drive the turning frame to turn over;

[0023] A second motor is fixed inside the processing table;

[0024] Two gears are symmetrically mounted on the two ends of the side wall of the flip frame. The second motor drives one of the gears to rotate, and the other gear is coaxially connected to the cutting knife.

[0025] A synchronous belt, which is installed on the outer rings of the two gears;

[0026] After the second motor is started, the output shaft drives the gear connected to it to rotate. After the gear rotates, the synchronous belt connected to it drives another gear to rotate, thereby driving the cutting knife connected to it to rotate through another gear, so that the pipe is cut by the rotating cutting knife;

[0027] The cutting knife and the aligned ends of the two support tubes are in the same vertical plane, so that the cutting position of the cutting knife is aligned with the opposite ends of the two support tubes, so that the support tubes can be pushed apart during cutting to avoid interference with the cutting by the support tubes.

[0028] Preferably, the support assembly further comprises:

[0029] Two air bags are respectively fixed on the outer walls of the two support tubes;

[0030] Two air pumps are respectively fixed inside the two support tubes, and input ends of the two air pumps are respectively connected to the two air bags;

[0031] Two connecting pipes are respectively penetrated through the opposite ends of the supporting pipe to connect the spaces where the two air pumps are located with the outside world;

[0032] After the air pump is started, it drives the airflow into the interior of the airbag, so that the airbag expands after being inflated. After the airbag is inflated and expanded, the gap between the support tube and the inner wall of the pipe fitting is filled, so that the space left by the outer diameter of the support tube for the convenience of inserting the pipe fitting can be filled during cutting, so that the support tube supports the pipe fitting more stably, thereby further reducing the deformation of the pipe fitting during the cutting process, which is conducive to reducing the interference of deformation on the cutting accuracy of the pipe fitting;

[0033] A pressure sensor is provided inside the airbag, so that when the air pump inflates the inside of the airbag, the air pressure inside the airbag can be controlled, so that the airbag is fully inflated to support the cutting of the pipe, and it is helpful to avoid the situation where the air pump is damaged by excessive inflation of the airbag;

[0034] The connecting pipe can connect the space where the air pump is located with the external space, which is beneficial to the air pressure balance in the space where the air pump is located and helps to avoid damage to the air pump due to air pressure imbalance.

[0035] Preferably, the support assembly further comprises:

[0036] A first output tube, one end of which is fixed to the output end of the air pump and the other end of which is connected to the air bag;

[0037] A second output pipe, one end of which is fixedly connected to the first output pipe, and the other end of which is connected to the space where the air pump is located;

[0038] A first input tube, one end of which is fixed to the input end of the air pump and the other end of which is connected to the air bag;

[0039] A second input pipe, one end of which is fixedly connected to the first input pipe, and the other end of which is connected to the space where the air pump is located;

[0040] Four solenoid valves, respectively fixed to the ends of the first output pipe and the second output pipe, the first input pipe, and the second input pipe;

[0041] When only the electromagnetic valves inside the first output pipe and the second input pipe are opened, the air pump is started to transport the airflow inside the space to the inside of the airbag, thereby inflating the inside of the airbag, so that the airbag is inflated when the pipe needs to be cut;

[0042] When only the solenoid valves inside the second output pipe and the first input pipe are opened, the air pump is started to transport the gas inside the airbag to the space where the air pump is located, thereby expelling the air inside the airbag and causing the airbag to retract, thereby canceling the support of the airbag for the pipe. When the pipe needs to be transported, the friction component of the airbag on the inner wall of the pipe can be reduced, thereby helping to avoid obstruction to the movement of the pipe.

[0043] Preferably, the support assembly further comprises:

[0044] Two third magnets are respectively fixed to opposite ends of the two support tubes, and the third magnets are wrapped inside the airbag;

[0045] The two third magnets have opposite magnetic poles, so that the two third magnets attract each other through magnetic attraction, thereby driving the two support tubes to attract each other closer, which is conducive to pulling the two support tubes closer to each other, and is conducive to avoiding the support tube from deviating outward when supported by magnetic force, and is conducive to improving the stability of the support tube when supporting the pipe fitting.

[0046] Preferably, the support assembly further comprises:

[0047] Two wear pads, respectively detachably fixedly mounted on opposite ends of the two third magnets;

[0048] The provision of the two wear pads ensures that when the cutting knife cuts and pushes the two support tubes away from each other, the cutting knife will not directly contact the support tubes and the third magnet, but will push the wear pads to push the support tubes away from each other, thereby helping to avoid the situation where the cutting knife causes wear of the support tubes and the third magnet. Through the provision of the wear pads, after the cutting knife pushes the wear pads to cause wear of the wear pads, the wear pads can be disassembled and replaced, thereby facilitating the replacement of wear parts.

[0049] Preferably, the conveying assembly comprises:

[0050] Two groups of mobile racks, two of which form a group, the two groups of mobile racks are symmetrically installed at both ends of the processing table, and the two mobile racks in the same group are symmetrically installed at the end of the processing table;

[0051] Four groups of rotating rollers, two of which form a group, and each group of rotating rollers is symmetrically mounted inside each of the moving frames;

[0052] Four third motors are respectively fixed on the top of each of the moving frames, and the four third motors respectively drive one of the rotating rollers in the four groups to rotate;

[0053] Four conveyor belts are respectively installed on the outer rings of the four groups of rotating rollers;

[0054] After the third motor is started, the output shaft drives the rotating roller connected thereto to rotate. After the rotating roller rotates, it drives the conveyor belt connected thereto to drive. After the conveyor belt drives, it can push the pipe fittings to move, thereby realizing the transportation of the pipe fittings.

[0055] Preferably, the conveying assembly further comprises:

[0056] Two groups of brackets, two processing tables form one group, the two groups of brackets are symmetrically fixed at the two ends of the processing table, and all the movable racks are slidably inserted into the interior of each bracket;

[0057] Four groups of springs, a plurality of the springs form a group, and the springs in the same group are fixedly connected between the corresponding brackets and the movable frame in a linear array;

[0058] The movable rack is slidably connected to the bracket. For pipes of different sizes, the movable rack can be pushed to fit the pipes under the elastic force of the spring, so that there is sufficient friction between the conveyor belt and the pipes to transport the pipes through transmission.

[0059] In a second aspect, a method for using a hydraulic pipe cutting device is provided, the method comprising the following steps:

[0060] Step 1: Install the pipe fitting: insert the pipe fitting into the first inner groove so that the support assembly supports the inner wall of the pipe fitting;

[0061] Step 2: Adjust the cutting position: drive the inserted pipe to move through the conveying assembly so that the pipe is aligned with the position of the cutting assembly and moves and adjusts the cutting position;

[0062] Step 3: Cutting: Start the cutting assembly and cut the pipe at the position aligned with the cutting assembly to complete the cutting process;

[0063] Step 4, unloading: start the conveying component again to drive the part of the pipe that has been cut to move away from the first inner groove for unloading, and at the same time drive the part of the pipe that needs to be cut to move into the inside of the first inner groove for further cutting.

[0064] Compared with the prior art, the present invention has the following beneficial effects:

[0065] The present invention arranges the support assembly so that the pipe will not produce a large deformation when being cut and extruded, which helps to avoid the situation where the pipe is deformed during cutting and the cutting accuracy is affected. At the same time, due to the suspended arrangement of the support assembly, the existence of the support assembly will not affect the pipe passing through the first inner groove, so that pipes of any length can pass through the interior of the first inner groove and be supported by the support assembly, thereby facilitating the cutting of pipes of any length.

DETAILED DESCRIPTION

[0076] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0078] The first inner groove 101 is provided through the inside of the processing table 1 and is used for the pipe 2 to pass through for cutting processing;

[0079] The second inner groove 102 is provided inside the processing table 1;

[0080] A cutting assembly, installed inside the processing table 1, for cutting the pipe 2;

[0081] A support assembly is suspended and installed inside the first inner groove 101 by magnetic force, and is used to support the inner wall of the pipe 2 that is cut through the inside of the first inner groove 101;

[0082] The conveying assembly is installed at both ends of the processing table 1 and is used to drive the pipe 2 to move so as to drive the pipe 2 to move and adjust the cutting position;

[0083] When cutting the hydraulic pipe fitting 2, the rubber hydraulic pipe fitting 2 itself is easy to deform, so when the cutting knife contacts the hydraulic pipe fitting 2, there is a situation that the hydraulic pipe fitting 2 is deformed. If the hydraulic pipe fitting 2 is compressed and deformed, it will cause the cutting position to deviate, so that the deviation caused by the deformation will cause cutting errors and affect the cutting accuracy.

[0084] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the staff inserts the pipe 2 to be cut into the first inner groove 101. When inserting, the support component suspended in the first inner groove 101 passes through the inside of the pipe 2, so that the support component supports the inside of the pipe 2, so that when the pipe 2 is cut, the pipe 2 is supported by the support component, so that the pipe 2 will not be greatly deformed when it is cut and squeezed, which is conducive to avoiding the situation where the pipe 2 is deformed during cutting and the cutting accuracy is affected. At the same time, due to the suspended setting of the support component, the existence of the support component will not affect the pipe 2 passing through the first inner groove 101, so that any length of the pipe 2 can pass through the inside of the first inner groove 101 and be supported by the support component, so as to facilitate the cutting of any length of the pipe 2;

[0085] Then the staff starts the cutting assembly, and the cutting assembly cuts the pipe 2 after it is started, thereby realizing the cutting process of the pipe 2;

[0086] When cutting the pipe 2, the staff starts the conveying component, which drives the pipe 2 to move, thereby driving the pipe 2 itself to move, so that the pipe 2 can adjust its moving position through its own movement, which is conducive to adjusting the cutting position according to the required cutting size.

[0091] A group of second magnets 302 corresponds to one first magnet 301, and the upper part of the first magnet 301 is opposite to the same magnetic pole of the upper second magnet 302, and the lower part of the first magnet 301 is opposite to the same magnetic pole of the lower second magnet 302, so that the two second magnets 302 support the first magnet 301 in mid-air through magnetic repulsion, thereby forming a suspended support for the support tube 3. The two groups of second magnets 302 form a suspended support for the two support tubes 3, and the opposite ends of the two support tubes 3 are aligned with the cutting assembly, so that the cutting assembly can push the two support tubes 3 to separate when cutting the pipe fitting 2, which is beneficial to avoid the situation where the support of the support tube 3 hinders the cutting of the pipe fitting 2.

After the gear 404 rotates, the synchronous belt 405 connected thereto drives another gear 404 to rotate, thereby driving the cutting knife 4 connected thereto to rotate through the other gear 404, so that the rotating cutting knife 4 cuts the pipe 2;

[0101] The cutting knife 4 and the aligned ends of the two support tubes 3 are in the same vertical plane, so that the cutting position of the cutting knife 4 is aligned with the opposite ends of the two support tubes 3, so that the support tubes 3 can be pushed apart during cutting to avoid interference with the cutting caused by the support tubes 3.

After the airbag 5 is inflated and expanded, the gap between the support tube 3 and the inner wall of the pipe 2 is filled, so that the space left by the outer diameter of the support tube 3 for the convenience of inserting the pipe 2 can be filled during cutting, so that the support of the support tube 3 to the pipe 2 is more stable, thereby further reducing the deformation of the pipe 2 during the cutting process, which is conducive to reducing the interference of the deformation on the cutting accuracy of the pipe 2;

[0107] A pressure sensor is provided inside the airbag 5, so that when the air pump 501 inflates the inside of the airbag 5, the air pressure inside the airbag 5 after inflation can be controlled, so that the airbag 5 is fully inflated to support the cutting of the pipe 2, and it is helpful to avoid the situation where the air pump 501 is damaged due to excessive inflation of the airbag 5 by the air pump 501;

[0108] The connecting pipe 507 can connect the space where the air pump 501 is located with the external space, which is beneficial to the air pressure balance in the space where the air pump 501 is located, and is beneficial to avoiding the situation where the air pump 501 is damaged due to air pressure imbalance.

[0115] When only the electromagnetic valve 506 inside the first output pipe 502 and the second input pipe 505 is opened, the air pump 501 is started to transport the airflow inside the space to the inside of the airbag 5, thereby inflating the inside of the airbag 5, so that the airbag 5 is inflated when the pipe 2 needs to be cut;

[0116] When only the solenoid valve 506 inside the second output pipe 503 and the first input pipe 504 is opened, the air pump 501 is started and the gas inside the airbag 5 is transported to the space where the air pump 501 is located, thereby expelling the air inside the airbag 5 and causing the airbag 5 to retract, thereby canceling the support of the airbag 5 on the pipe 2. Therefore, when the pipe 2 needs to be transported, the friction component of the airbag 5 on the inner wall of the pipe 2 can be reduced, thereby helping to avoid obstruction to the movement of the pipe 2.

[0117] As an optional embodiment, the support assembly further includes:

[0118] Two third magnets 6 are fixed to opposite ends of the two support tubes 3, respectively, and the third magnets 6 are wrapped inside the airbag 5;

[0119] The two third magnets 6 have opposite magnetic poles, so that the two third magnets 6 are attracted to each other by magnetic attraction, thereby driving the two support tubes 3 to attract each other closer, which is beneficial to pulling the two support tubes 3 closer to each other, and is beneficial to avoiding the support tube 3 from deviating outward when supported by magnetic force, and is beneficial to improving the stability of the support tube 3 when supporting the pipe fitting 2.

[0133] like Fig. 9 A method for using a hydraulic pipe cutting device is shown, the method comprising the following steps:

[0134] Step 1: Install the pipe fitting: insert the pipe fitting 2 into the first inner groove 101 so that the support assembly supports the inner wall of the pipe fitting 2;

[0135] Step 2: Adjust the cutting position: drive the inserted pipe 2 to move by the conveying assembly so that the pipe 2 is aligned with the position of the cutting assembly and moves and adjusts the cutting position;

[0138] Working principle of the present invention: the staff inserts the pipe fitting 2 to be cut into the first inner groove 101. When inserting, the support assembly suspended in the first inner groove 101 passes through the inside of the pipe fitting 2, so that the support assembly supports the inside of the pipe fitting 2, so that when the pipe fitting 2 is cut, the pipe fitting 2 is supported by the support assembly, so that the pipe fitting 2 will not be greatly deformed when being cut and squeezed, which is conducive to avoiding the situation where the pipe fitting 2 is affected by the deformation during cutting and the cutting accuracy is affected. At the same time, due to the suspended setting of the support assembly, the existence of the support assembly will not affect the pipe fitting 2 passing through the first inner groove 101, so that any length of the pipe fitting 2 can pass through the inside of the first inner groove 101 and be supported by the support assembly, so as to facilitate the cutting of any length of the pipe fitting 2;

[0139] Then the staff starts the cutting assembly, and the cutting assembly cuts the pipe 2 after it is started, thereby realizing the cutting process of the pipe 2;

[0140] When cutting the pipe 2, the staff starts the conveying component, which drives the pipe 2 to move, thereby driving the pipe 2 itself to move, so that the pipe 2 can adjust its moving position through its own movement, which is conducive to adjusting the cutting position according to the required cutting size.

[0141] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
