Description

Technical Field

[0001] This utility model relates to the field of hydraulic shearing technology, specifically to a hydraulic shear for ferrous metal casting processing. Background Technology

[0002] In the field of ferrous metal casting and processing, castings are often accompanied by excess structures such as risers, flash, and burrs after forming. In addition, some castings have problems such as dimensional deviations and defects, which require precise cutting and sorting. Traditional processing methods mostly rely on manual cutting or ordinary mechanical shearing, which has disadvantages such as low efficiency, poor cut smoothness, and high labor intensity. Moreover, it is difficult to adapt to the processing needs of castings of different specifications, which can easily lead to material waste and safety hazards.

[0003] According to a public announcement (Publication No.: CN222726162U), a boring device for processing ferrous metal castings includes a pair of support frames. The ferrous metal casting sheet is moved through a pressing assembly via a conveyor belt. The pressing assembly presses the ferrous metal casting sheet to prevent it from shifting during punching. The position of the ferrous metal casting sheet to be punched is located between the support plates.

[0004] The aforementioned method, through the cooperation of components such as the support frame and support plate, fails to address the issue of limiting the movement trajectory of the shearing blade assembly by the limit rod, preventing its deviation. Simultaneously, the slow-speed design reduces inertial sway during shearing, resulting in a smoother cut and more precise dimensions. However, the friction buffering of the obstruction block and the vibration reduction and dispersion of the steel rope isolator significantly reduce the instantaneous impact force on the hydraulic cylinder, shearing blade, and frame. Consequently, the method cannot effectively limit the movement trajectory of the shearing blade assembly to prevent deviation, resulting in uneven cuts and inaccurate dimensions. This fails to significantly reduce the instantaneous impact force on the hydraulic cylinder, shearing blade, and frame, leading to the risk of component wear and cracking, increased maintenance costs, unstable equipment operation, material splashing, and sudden component failures. Furthermore, it increases the safety risks associated with equipment vibration and reduces the safety of the working environment, requiring further improvement. Utility Model Content To overcome the above-mentioned defects, the present invention provides a hydraulic shear for ferrous metal casting processing, which solves the problem in the prior art that the limiting rod cannot restrict the movement trajectory of the shearing blade assembly and prevent its deviation. At the same time, the slow-speed design reduces the inertial shaking during shearing, making the cut smoother and the size more accurate. The friction buffer of the barrier block and the vibration reduction and dispersion of the steel rope vibration isolator greatly reduce the instantaneous impact force of the hydraulic cylinder, shearing blade and frame.

[0005] According to one aspect, at least one embodiment of the present invention provides a hydraulic shear for ferrous metal casting, comprising: a frame, a feeding platform provided on the side of the frame, a hydraulic cylinder provided at the bottom of the frame, a shearing blade assembly fixedly connected to the piston end of the hydraulic cylinder, a hydraulic system unit provided on the side of the frame, a guardrail provided at the top of the frame, a limit buffer vibration isolation assembly provided on the inner wall of the frame, the limit buffer vibration isolation assembly including a support frame, the side of the support frame fixedly connected to the inner wall of the frame, a limit rod slidably connected to the inner wall of the support frame, the end of the limit rod away from the support frame fixedly connected to the side of the shearing blade assembly, a steel rope vibration isolator provided on the inner wall of the support frame, and an obstruction block fixedly connected to the inner wall of the support frame.

[0006] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, there are several obstruction blocks arranged in a linear array on the inner wall of the support frame, and the side of the obstruction block is set in an arc shape. The design of the obstruction block is beneficial to slow down the movement speed of the limit rod.

[0007] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the obstruction block is located on the displacement trajectory of the limiting rod, and a plurality of support frames are provided, in pairs, and symmetrically arranged along the vertical central axis of the frame. The provision of a plurality of support frames is beneficial for providing additional support and limiting for the hydraulic cylinder.

[0008] For example, in a hydraulic shear for ferrous metal casting and processing provided in at least one embodiment of the present invention, the steel rope vibration isolator is located at the bottom of the limiting rod, and the steel rope vibration isolator is located on the displacement trajectory of the limiting rod. The steel rope vibration isolator is beneficial to vibrate the hydraulic cylinder and the limiting rod, and reduce the impact when moving downward.

[0009] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the supporting frame is located on the side of the shearing blade assembly, and a plurality of limiting rods are provided, which are symmetrical to each other along the vertical central axis of the hydraulic cylinder. The provision of a plurality of limiting rods is beneficial to improving the limiting effect.

[0010] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the feed table is located on the side of the hydraulic system unit, and a ladder is provided on the side of the frame, the ladder being designed to facilitate users climbing onto the frame.

[0011] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the obstruction block is located at the top of the steel rope vibration isolator, and a support leg is provided at the bottom of the feeding platform.

[0012] According to another aspect, at least one embodiment of this utility model also provides a hydraulic shear for ferrous metal casting processing, comprising: a replaceable and disassembleable component provided on the side of the support frame, the replaceable and disassembleable component including a slot, the slot being opened on the side of the support frame; a pin block being fixedly connected to the side of the steel rope vibration isolator; one end of the pin block away from the steel rope vibration isolator penetrating through the inner wall of the slot; and a rotating shaft being rotatably connected to the other end of the pin block away from the steel rope vibration isolator; a locking rod penetrating through the circumference of the rotating shaft. Through the design of the pin block and the locking rod, the steel rope vibration isolator can be quickly replaced, preventing the steel rope vibration isolator from wearing out due to prolonged use and reducing its vibration reduction effect.

[0013] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the groove is rectangular, the locking rod is rectangular, the groove is located on the displacement trajectory of the pin block, and the groove and the locking rod are of the same shape, which is beneficial for the locking rod to pass through the groove.

[0014] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of this utility model, there are several of the pin blocks and locking rods arranged in a linear array on the side of the support frame, which is beneficial to improving the stability of the steel rope vibration isolator installation.

[0015] The beneficial effects of this utility model are as follows: This invention utilizes the interplay between components such as the limiting rod and steel rope vibration isolator within the limiting buffer vibration isolation assembly. This allows the limiting rod to restrict the movement trajectory of the shearing blade assembly, preventing deviation. Simultaneously, the slow-motion design reduces inertial swaying during shearing, resulting in smoother cuts and more precise dimensions. This design is suitable for the precision post-processing requirements of castings. The friction buffering of the barrier block and the vibration reduction and dispersion by the steel rope vibration isolator significantly reduce the instantaneous impact force on the hydraulic cylinder, shearing blade, and frame, minimizing component wear and cracking risks, and lowering maintenance costs. The slow-motion and vibration-damping design ensures smoother equipment operation, preventing material splashing, sudden component failures, and other potential hazards. It also reduces safety risks associated with equipment vibration and improves the safety of the working environment.

[0016] This invention utilizes the interplay between components such as slots, pins, shafts, and locking rods within the easily replaceable and disassembled assembly to achieve a quick-installation structure. This allows for rapid disassembly and installation of the steel rope vibration isolator without the need for complex tools, significantly reducing maintenance downtime and adapting to the efficient production rhythm of casting processing. The rotating locking mechanism of the locking rod securely fixes the position of the steel rope vibration isolator, preventing it from loosening or shifting during high-impact hydraulic shearing operations and ensuring the stable operation of its vibration damping and buffering function.

[0025] like Figures 1-5 As shown, this invention illustrates a hydraulic shear for ferrous metal casting processing according to one embodiment of the present invention. It includes a frame 1, a feeding platform 2 on the side of the frame 1, a hydraulic cylinder 3 at the bottom of the frame 1, a shearing blade assembly 4 fixedly connected to the piston end of the hydraulic cylinder 3, a hydraulic system unit 5 on the side of the frame 1, a guardrail 6 at the top of the frame 1, and a limit buffer vibration isolation assembly 7 on the inner wall of the frame 1. The limit buffer vibration isolation assembly 7 includes a support frame 71, the side of the support frame 71 fixedly connected to the inner wall of the frame 1, a limit rod 72 slidably connected to the inner wall of the support frame 71, one end of the limit rod 72 away from the support frame 71 fixedly connected to the side of the shearing blade assembly 4, a steel rope vibration isolator 74 on the inner wall of the support frame 71, and an obstruction block 73 fixedly connected to the inner wall of the support frame 71.

[0026] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, there are also: a plurality of obstruction blocks 73 are arranged in a linear array on the inner wall of the support frame 71, and the side of the obstruction blocks 73 is set in an arc shape. The design of the obstruction blocks 73 is beneficial to slow down the moving speed of the limit rod 72.

[0027] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the following is also included: the obstruction block 73 is located on the displacement trajectory of the limit rod 72, and a number of support frames 71 are provided, in pairs, and symmetrical to each other along the vertical central axis of the frame 1. The provision of a number of support frames 71 is beneficial to provide additional support and limit for the hydraulic cylinder 3.

[0028] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, a steel rope vibration isolator 74 is located at the bottom of the limiting rod 72. The steel rope vibration isolator 74 is located on the displacement trajectory of the limiting rod 72. The steel rope vibration isolator 74 is beneficial to vibrate the hydraulic cylinder 3 and the limiting rod 72, thereby reducing the impact when moving downward.

[0029] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, a support frame 71 is located on the side of the shearing blade assembly 4, and a plurality of limiting rods 72 are provided, which are symmetrical to each other along the vertical central axis of the hydraulic cylinder 3. The provision of a plurality of limiting rods 72 is beneficial to improving the limiting effect.

[0030] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the feed table 2 is located on the side of the hydraulic system unit 5, and a ladder is provided on the side of the frame 1. The ladder is designed to facilitate the user to climb onto the frame 1.

[0031] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, there is also: a blocking block 73 located on top of a steel rope vibration isolator 74, and a support leg provided at the bottom of the feed table 2.

[0032] This embodiment provides a hydraulic shear for ferrous metal casting. Through the cooperation of components such as the limiting rod 72 and the steel rope vibration isolator 74 inside the limiting buffer vibration isolation assembly 7, the limiting rod 72 restricts the movement trajectory of the shearing blade assembly 4, preventing it from deviating. At the same time, the slow-speed design reduces inertial swaying during shearing, resulting in a smoother cut and more precise dimensions, which is suitable for the precision post-processing requirements of castings. The friction buffer of the obstruction block 73 and the vibration reduction and dispersion of the steel rope vibration isolator 74 significantly reduce the instantaneous impact force on the hydraulic cylinder 3, shearing blade and frame 1, reducing the risk of component wear and cracking, and lowering maintenance costs. The slow-speed movement and vibration reduction design make the equipment run more smoothly, avoiding potential hazards such as material splashing and sudden component failures, while reducing the safety risks caused by equipment vibration and improving the safety of the working environment.

[0033] See in some examples Figures 1-5 The frame 1 serves as the core support structure, firmly supporting components such as the hydraulic cylinder 3 and the shearing blade assembly 4. The feed platform 2 guides ferrous metal castings and scrap steel into the shearing opening, providing a positioning reference for shearing. The hydraulic system unit 5 drives the hydraulic cylinder 3, converting high-pressure oil into thrust, which drives the shearing blade assembly 4 downward. Under the thrust of the cylinder, the shearing blade assembly 4 completes cold shearing of the material in the feed platform 2. The guardrail 6 ensures personnel safety during equipment operation and maintenance. All components are supported by the frame 1 and positioned by the feed platform 2. The coordinated operation of the hydraulic system (power supply), cylinder (force transmission), shearing blade (execution), and guardrail 6 (protection) enables efficient and safe shearing of ferrous metal materials, completing post-casting processing and scrap steel handling. A sliding limit rod 72 is fixed to the side of the shearing blade assembly 4. The limit rod 72 slides on the inner wall of the support frame 71, restricting the movement of the shearing blade assembly 4 as it moves up and down with the piston of the hydraulic cylinder 3. Several obstruction blocks 73 are set on the side of the limit rod 72 to prevent... The obstruction block 73 is located on the movement trajectory of the limiting rod 72, so that the limiting rod 72 contacts the obstruction block 73 when it moves downward, increasing the friction force when the limiting rod 72 moves downward, allowing the limiting rod 72 to move downward slowly. This buffers the downward movement speed of the shearing blade assembly 4 and the hydraulic cylinder 3. Below the limiting rod 72, a steel rope vibration isolator 74 is installed to reduce vibration and disperse impact force when the limiting rod 72 moves downward. The limiting rod 72 restricts the movement trajectory of the shearing blade assembly 4, preventing it from deviating. The slow-speed design reduces inertial swaying during shearing, resulting in a smoother cut and more precise dimensions. It is suitable for the precision post-processing requirements of castings. The friction buffer of the damping block 73 and the vibration reduction and dispersion of the steel rope vibration isolator 74 significantly reduce the instantaneous impact force on the hydraulic cylinder 3, shear blade and frame 1, reducing the risk of component wear and cracking, and lowering maintenance costs. The slow-speed movement and vibration reduction design make the equipment run more smoothly, avoiding potential hazards such as material splashing and sudden component failures. At the same time, it reduces the safety risks caused by equipment vibration and improves the safety of the working environment.

[0034] refer to Figures 1-5 In some embodiments, a hydraulic shear for ferrous metal casting further includes: a replacement and disassembly assembly 8 provided on the side of a support frame 71, the replacement and disassembly assembly 8 including a slot 81, the slot 81 being formed on the side of the support frame 71; a pin block 82 fixedly connected to the side of a steel rope vibration isolator 74, one end of the pin block 82 away from the steel rope vibration isolator 74 penetrating through the inner wall of the slot 81; and a rotating shaft 83 rotatably connected to the other end of the pin block 82 away from the steel rope vibration isolator 74, with a locking rod 84 penetrating through the circumference of the rotating shaft 83. The design of the pin block 82 and the locking rod 84 allows for quick replacement of the steel rope vibration isolator 74, preventing wear and tear from prolonged use and reducing its vibration damping effect.

[0035] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, the following is also included: the slot 81 is rectangular, the locking rod 84 is rectangular, the slot 81 is located on the displacement trajectory of the pin block 82, and the slot 81 and the locking rod 84 are set in the same shape, which is beneficial for the locking rod 84 to pass through the slot 81.

[0036] For example, in a hydraulic shear for ferrous metal casting processing provided in at least one embodiment of the present invention, there are also: a plurality of pin blocks 82 and locking rods 84 are provided, and a plurality of them are arranged in a linear array on the side of the support frame 71, which is beneficial to improving the firmness of the installation of the steel rope vibration isolator 74.

[0037] In this embodiment, by utilizing the interoperability of components such as the slot 81, pin block 82, rotating shaft 83, and locking rod 84 inside the easily replaceable and disassembleable assembly 8, a quick-installation structure is achieved through the slot 81, pin block 82, and locking rod 84. This allows for rapid disassembly and installation of the steel rope vibration isolator 74 without the need for complex tools, significantly reducing maintenance downtime and adapting to the efficient production rhythm of casting processing. The rotational locking method of the locking rod 84 can firmly fix the position of the steel rope vibration isolator 74, preventing it from loosening or shifting during hydraulic shearing high-impact operations and ensuring the stable performance of the vibration reduction and buffering function.

[0038] In this embodiment, a slot 81 is formed on the side of the support frame 71, and a pin block 82 is fixed to the side of the steel cable vibration isolator 74. First, the locking rod 84 is rotated until it is parallel to the slot 81. Then, the pin block 82 is inserted through the inner wall of the slot 81, thereby temporarily fixing the steel cable vibration isolator 74 to the inner wall of the support frame 71. After the pin block 82 is inserted, the rotating shaft 83 is rotated, which drives the locking rod 84 to rotate and be perpendicular to the side of the slot 81, thereby temporarily fixing the position of the pin block 82 and locking the position of the steel cable vibration isolator 74. When it needs to be replaced, the rotating shaft 83 is rotated again. 3. Rotate the locking rod 84 until it is parallel to the slot 81, so that the pin block 82 can be removed from the slot 81 and the steel rope vibration isolator 74 can be disassembled. Through the quick-release structure of the slot 81, pin block 82 and locking rod 84, the steel rope vibration isolator 74 can be quickly disassembled and installed without complicated tools, which greatly shortens the maintenance downtime and is suitable for the efficient production rhythm of casting processing. The locking method of the locking rod 84 can firmly fix the position of the steel rope vibration isolator 74, prevent it from loosening and shifting during hydraulic shear high impact operation, and ensure that the vibration reduction and buffering function is stable.
