Description
Technical Field
[0001] This utility model relates to the field of steel strip processing technology, and in particular to a movable hydraulic shear. Background Technology
[0002] Steel strip, also known as strip steel, is a narrow and long steel plate with a width of no more than 1300mm. It is generally supplied in coils. Made of carbon steel, it serves as the traction and carrying component of belt conveyors and is also used for bundling goods. Steel strips are produced by various steel rolling mills to meet the needs of different industrial sectors, and their production involves multiple processes. First, iron ore is smelted at high temperatures to remove impurities and oxides. Then, it undergoes a reduction reaction in a converter or electric furnace to produce steel. Thin slabs are then formed through continuous casting. During processing, steel strips require hydraulic shearing.
[0003] However, during the hydraulic shearing process, due to the lack of an effective positioning and constraint structure, the balance of external forces on the steel strip is broken instantly after cutting. In addition, the strip loses its integrity after cutting, and under the influence of its own weight and the vibration generated during the operation of the hydraulic shear, it is very easy to deviate and fall off. This not only increases the difficulty of subsequent collection and sorting, but may also cause safety hazards, or even lead to processing interruption, affecting production efficiency and processing accuracy. Utility Model Content
[0004] The purpose of this invention is to solve the problem in the existing technology where, during hydraulic shearing, the lack of an effective positioning and constraint structure disrupts the balance of external forces on the steel strip after cutting. Furthermore, the strip loses its integrity after cutting and is prone to shifting and falling under the influence of its own weight and vibrations generated during hydraulic shearing. This not only increases the difficulty of subsequent collection and sorting but also poses safety hazards and may even lead to processing interruptions, affecting production efficiency and processing accuracy. Therefore, this invention proposes a movable hydraulic shear.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a movable hydraulic shear, including a body and a blocking device. A hydraulic shear is mounted on the upper surface of the body, and a pulley is rotatably connected to the lower surface of the body. A base is mounted on the lower surface of the body, and a slide rail is fixedly connected to the surface of the base. The pulley moves along the slide rail on the surface of the base. The blocking device is located on one side of the body and includes a bracket fixedly connected to the body. A rotating rod is rotatably connected to the surface of the bracket, and a rocker arm is fixedly connected to the surface of the rotating rod. A baffle is fixedly connected to the surface of the rocker arm, and a motor is fixedly connected to the surface of the bracket. The drive end of the motor is fixedly connected to the rotating rod. By setting up the blocking device and the motor-driven, spring-fixed structure, the baffle can be flexibly raised to contain the cut steel strip, effectively reducing the steel strip from falling. Pressing the round block resets the baffle, making operation convenient and efficient, ensuring the safety and cleanliness of the processing site, and reducing equipment failures and safety risks caused by falling steel strips.
[0006] Preferably, a stop bar is fixedly connected to one end of the baffle. The stop bar is cylindrical, and a locking block is fixedly connected to one side of the machine body. By setting the stop bar, during the baffle's lifting process, the stop bar cooperates with the fixed rod to provide guidance for the baffle's lifting, ensuring that the baffle can move accurately to the predetermined position and preventing the baffle from shifting or shaking during the lifting process.
[0007] Preferably, the surface of the card block has a hole, and a fixing rod is slidably connected to the inner wall of the hole. The surface of the fixing rod has an angle, and the stop rod contacts the fixing rod. By setting the fixing rod, when the motor drives the baffle to rise and reach the predetermined position, the spring generates elastic force to squeeze the fixing rod into the stop rod, thus fixing the baffle. In this way, the baffle can stably surround the corners of the machine body, effectively blocking the cut steel strip, reducing its falling, and ensuring the stability of the baffle position during the operation of the device.
[0008] Preferably, a round block is fixedly connected to the lower surface of the fixing rod, and a spring is sleeved on the surface of the fixing rod. The two ends of the spring are fixedly connected to the locking block and the round block, respectively. A binding hole is opened on the surface of the stop rod, and the fixing rod is inserted into the binding hole on the surface of the stop rod. By setting the spring, when the baffle is raised to the predetermined position, the spring loses its binding force and generates elastic force, which squeezes the fixing rod into the stop rod, thereby fixing the baffle in that position, so that the baffle can stably block the cut steel strip and prevent the steel strip from falling.
[0009] Preferably, a propulsion assembly is provided on the lower surface of the machine body. The propulsion assembly includes a hollow tube, which is fixedly connected to the base. A push rod is fixedly connected to one end of the machine body and slidably connected to the hollow tube. A piston pad is fixedly connected to the end of the push rod away from the machine body. By setting up the propulsion assembly, the kinetic energy of the machine body's movement is used to achieve the circulation and ejection of gas inside the hollow tube through the linkage of the push rod and the piston pad. This precisely cleans the dust at the contact point between the slide rail and the pulley, reducing the impact of dust accumulation on the pulley's operation, reducing wear between the pulley and the slide rail, ensuring smooth movement of the machine body, improving the stability and service life of the equipment, and eliminating the need for an additional power source, thus saving energy and being environmentally friendly.
[0010] Preferably, a flexible hose is fixedly connected to the end of the hollow tube away from the push rod, and an air outlet is opened at one end of the flexible hose. The flexible hose is fixedly connected to the machine body. By setting the flexible hose, the gas squeezed by the piston pad in the hollow tube is transmitted to the air outlet, so that the gas can be accurately sprayed to the contact point between the slide rail and the pulley, thereby cleaning the dust in that part.
[0011] Preferably, there are two hollow tubes, which are arranged symmetrically.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] In this invention, by setting up a shielding device, when in use, the motor is started, and the motor drives the rotating rod to rotate. The rotating rod drives the rocker arm, and the rocker arm drives the baffle to rise, thus shielding the corners of the machine body. At this time, the baffle rod and the fixed rod abut against each other, and the fixed rod touches the baffle rod at an angle. The fixed rod is forced to move downward, and the baffle continues to rotate until it is vertical. After it is vertical, the binding hole on the surface of the baffle rod is opposite to the fixed rod. At this time, the fixed rod loses the pressure of the baffle rod, and the spring loses its binding force, generating elastic force to squeeze the fixed rod into the binding hole. At this time, the baffle is fixed, and the baffle supports and shields the corners of the machine body. By setting up a shielding device, motor drive and spring fixing structure, the baffle can be flexibly raised to shield the cut steel strip, effectively reducing the steel strip falling. The baffle can be reset by pressing the round block. The operation is convenient and efficient, ensuring the safety and cleanliness of the processing site, and reducing equipment failure and safety risks caused by the steel strip falling.
[0014] In this invention, by setting up a propulsion component, when the equipment is started, the cylinder in the base pushes the machine body to move along the slide rail. The machine body pushes the push rod and piston pad to move. When the piston pad moves, it compresses the gas in the hollow tube and sprays it out through the hose. The position of the air outlet corresponds to the pulley, which facilitates the cleaning of dust at the contact point between the slide rail and the pulley. When the machine body moves in the opposite direction, it drives the push rod and piston pad to reset. The gas re-enters the hollow tube through the air outlet, preparing for the next cleaning. By setting up the propulsion component, the kinetic energy of the machine body's movement is used to achieve the circulation and spraying of gas in the hollow tube through the linkage of the push rod and the piston pad. This accurately cleans the dust at the contact point between the slide rail and the pulley, reduces the impact of dust accumulation on the pulley's operation, reduces wear on the pulley and slide rail, ensures smooth movement of the machine body, improves the stability and service life of the equipment, and eliminates the need for an additional power source, making it energy-saving and environmentally friendly.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a movable hydraulic shear, including a body 1 and a blocking device 4. The upper surface of the body 1 is provided with a hydraulic shear 2, the lower surface of the body 1 is rotatably connected with a pulley 3, the lower surface of the body 1 is provided with a base 5, the surface of the base 5 is fixedly connected with a slide rail, the pulley 3 moves along the slide rail on the surface of the base 5, and the blocking device 4 is provided on one side of the body 1.
[0022] In this implementation scheme: the shielding device 4 includes a bracket 44, which is fixedly connected to the machine body 1. A rotating rod 43 is rotatably connected to the surface of the bracket 44. A rocker arm 45 is fixedly connected to the surface of the rotating rod 43. A baffle 41 is fixedly connected to the surface of the rocker arm 45. A motor 42 is fixedly connected to the surface of the bracket 44. The drive end of the motor 42 is fixedly connected to the rotating rod 43. By setting up the shielding device 4, the motor 42 drives the fixed structure with the spring 410, which can flexibly raise the baffle 41 to surround the cut steel strip, effectively reducing the steel strip from falling. Pressing the round block 47 can reset the baffle 41. The operation is convenient and efficient, ensuring the safety and cleanliness of the processing site and reducing equipment failure and safety risks caused by the steel strip falling.
[0023] Specifically, a stop bar 48 is fixedly connected to one end of the baffle 41. The stop bar 48 is cylindrical. A locking block 46 is fixedly connected to one side of the body 1. By setting the stop bar 48, during the process of the baffle 41 rising, the stop bar 48 cooperates with the fixed rod 411 to provide guidance for the rise of the baffle 41, ensuring that the baffle 41 can move accurately to the predetermined position and preventing the baffle 41 from shifting or shaking during the rising process.
[0024] Specifically, a hole is provided on the surface of the locking block 46, and a fixing rod 411 is slidably connected to the inner wall of the hole on the surface of the locking block 46. The surface of the fixing rod 411 is provided with an angle, and the stop rod 48 contacts the fixing rod 411. By setting the fixing rod 411, when the motor 42 drives the baffle 41 to rise and reach the predetermined position, the spring 410 generates elastic force to squeeze the fixing rod 411 into the stop rod 48, so that the baffle 41 is fixed. In this way, the baffle 41 can stably surround the corner of the machine body 1, effectively blocking the cut steel strip, reducing its falling, and ensuring the stability of the position of the baffle 41 during the operation of the device.
[0025] Specifically, a round block 47 is fixedly connected to the lower surface of the fixing rod 411, and a spring 410 is sleeved on the surface of the fixing rod 411. The two ends of the spring 410 are fixedly connected to the locking block 46 and the round block 47, respectively. A binding hole is opened on the surface of the stop rod 48. The fixing rod 411 and the stop rod 48 are inserted into the binding hole by the spring 410. When the baffle 41 rises to the predetermined position, the spring 410 loses its binding force and generates elastic force, which squeezes the fixing rod 411 into the stop rod 48, thereby fixing the baffle 41 in this position, so that the baffle 41 can stably block the cut steel strip and prevent the steel strip from falling.
[0026] Specifically, a propulsion assembly 49 is provided on the lower surface of the body 1. The propulsion assembly 49 includes a hollow tube 491, which is fixedly connected to the base 5. A push rod 492 is fixedly connected to one end of the body 1. The push rod 492 is slidably connected to the hollow tube 491. A piston pad 494 is fixedly connected to the end of the push rod 492 away from the body 1.
[0027] In this embodiment: by setting up the propulsion component 49, the kinetic energy of the movement of the machine body 1 is used to realize the circulation and ejection of gas in the hollow tube 491 through the linkage of the push rod 492 and the piston pad 494, which accurately cleans the dust at the contact point between the slide rail and the pulley 3, reduces the impact of dust accumulation on the operation of the pulley 3, reduces the wear of the pulley 3 and the slide rail, ensures the smooth movement of the machine body 1, improves the stability and service life of the equipment, and at the same time, no additional power source is required, which is energy-saving and environmentally friendly.
[0028] Specifically, a flexible hose 493 is fixedly connected to the end of the hollow tube 491 away from the push rod 492. An air outlet is opened at one end of the flexible hose 493, and the flexible hose 493 is fixedly connected to the body 1.
[0029] In this embodiment: by setting a hose 493, the gas squeezed by the piston pad 494 in the hollow tube 491 is transmitted to the air outlet, so that the gas can be accurately sprayed to the contact point between the slide rail and the pulley 3, thereby cleaning the dust in that part.
[0030] Specifically, there are two hollow tubes 491, which are arranged symmetrically.
[0031] Working principle: By setting up the blocking device 4, when in use, the motor 42 is started, and the motor 42 drives the rotating rod 43 to rotate. The rotating rod 43 drives the rocker arm 45, and the rocker arm 45 drives the baffle 41 to rise, blocking the corners of the machine body 1. At this time, the baffle 48 abuts against the fixed rod 411, and the fixed rod 411 touches the baffle 48 at an angle. The fixed rod 411 moves downward under force, and the baffle 41 continues to rotate until it is vertical. After it is vertical, the binding hole on the surface of the baffle 48 is aligned with the fixed rod 411. At this time, the fixed rod 411 loses the restraint of the baffle 48. When pressure is applied, the spring 410 loses its restraint and generates elastic force to squeeze the fixing rod 411 into the restraint hole. At this time, the baffle 41 is fixed and supports the corners of the machine body 1. By setting the shielding device 4 and the motor 42 driving the structure fixed to the spring 410, the baffle 41 can be flexibly raised to shield the cut steel strip, effectively reducing the steel strip from falling. Pressing the round block 47 can reset the baffle 41. The operation is convenient and efficient, ensuring the safety and cleanliness of the processing site and reducing equipment failure and safety risks caused by the steel strip falling.
[0032] By setting the propulsion component 49, when the equipment is started, the cylinder in the base 5 pushes the machine body 1 to move along the slide rail. The machine body 1 pushes the push rod 492 and piston pad 494 to move. When the piston pad 494 moves, it squeezes the gas in the hollow tube 491 and sprays it out through the hose 493. The position of the air outlet corresponds to the pulley 3, which facilitates the cleaning of dust at the contact point between the slide rail and the pulley 3. When the machine body 1 moves in the opposite direction, it drives the push rod 492 and piston pad 494 to reset. The gas re-enters the hollow tube 491 through the air outlet, preparing for the next cleaning. By setting the propulsion component 49, the kinetic energy of the machine body 1 is used to achieve the circulation and spraying of gas in the hollow tube 491 through the linkage of the push rod 492 and piston pad 494. This accurately cleans the dust at the contact point between the slide rail and the pulley 3, reduces the impact of dust accumulation on the operation of the pulley 3, reduces the wear of the pulley 3 and the slide rail, ensures smooth movement of the machine body 1, improves the stability and service life of the equipment, and eliminates the need for an additional power source, making it energy-saving and environmentally friendly.
