Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet processing equipment, and in particular to an adjustable steel plate cross-cutting machine blade holder. Background Technology

[0002] In the field of sheet metal processing, steel plate cross-cutting machines are common equipment used to cut steel plates into the required dimensions. With the diversification of industrial demands, the requirements for the cutting precision and efficiency of steel plates are becoming increasingly stringent. A steel plate cross-cutting machine is a device used to cut steel plates laterally according to set dimensions. It typically consists of a blade holder, transmission device, and control system, and features high automation, high cutting precision, and high production efficiency, making it widely used in industries such as steel processing and machinery manufacturing.

[0003] A search revealed that Chinese announcement number CN222569418U discloses an anti-tilting cross-cutting machine, relating to the field of cross-cutting machine technology. The machine includes a frame, a transmission mechanism, a limiting mechanism, and a cutting assembly. The transmission mechanism has adjustment cavities on opposite sides, each containing teeth. The limiting mechanism has a set of clamping adjustment components, each comprising several eccentric wheel structures, an adjusting rack, and a pull rod structure. The eccentric wheel structures mesh with the teeth in the adjustment cavities and the adjusting rack. The pull rod structure moves the adjusting rack, causing the eccentric wheel structures to rotate to different positions, thus limiting the movement of plates of different widths during transmission. The cutting assembly is mounted on the frame and positioned close to the transmission mechanism for cutting the plates. This invention achieves better limiting effect by using several eccentric wheel structures to clamp and adjust the plates.

[0004] Although the aforementioned patent can clamp and fix the bar stock, its shearing components cannot be adjusted, making it difficult to adapt to the shearing requirements of steel plates of different thicknesses, resulting in low processing efficiency. Furthermore, improper tool holder clearance can easily cause uneven cuts on the steel plate or accelerated tool wear. Therefore, an adjustable steel plate shearing machine tool holder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable steel plate shearing machine cutter holder, which aims to improve the problem of low processing efficiency caused by the inability of the existing technology to adapt to the shearing requirements of steel plates of different thicknesses.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable steel plate shearing machine cutter holder includes a housing, an adjustment mechanism installed on the top of the housing, multiple tilting mechanisms provided on one side of the adjustment mechanism, a positioning mechanism installed on one side of the housing, an installation mechanism provided on the inner wall of the adjustment mechanism, a sensor installed on one side of the housing, and a limiting mechanism fixedly connected inside the housing.

[0009] With the above technical solution, when the motor is started, the motor drives the lead screw to rotate. The rotation of the lead screw causes the moving table to move up or down along its thread, thereby adjusting the position of the lower blade to adapt to steel plates of different thicknesses. The top support of the moving table ensures the stability of the processed material, and the guide assembly ensures the accurate trajectory during the movement.

A cutting plate is installed at the bottom of the connecting plate.

[0012] With the above technical solution, the second motor is fixed on one side of the housing, and its drive end is connected to a screw. The rotating screw drives the externally threaded moving plate to move linearly. The hydraulic cylinders on both sides of the top of the moving plate provide additional power support to ensure that the cutting plate can move smoothly and remain stable during the processing.

A motor is fixedly connected to the outside of the rotating plate. A worm is fixedly connected to the drive end of the motor. The worm and the worm gear are meshed together.

[0018] With the above technical solution, the top of the extension plate is fixedly connected to the bottom of the support plate, providing a solid support. The worm gear on the adjacent side is connected to the rotating plate. The rotating plate adjusts the tilt angle of the cutting plate by rotating. The motor fixed outside the rotating plate drives the worm to rotate. The worm meshes with the worm wheel to transmit power.

[0019] As a further description of the above technical solution:

[0020] The positioning mechanism includes multiple cylinders. The top of each cylinder is fixedly connected to one side of the housing. A buffer spring is sleeved on the outside of each cylinder. A positioning block is fixedly connected to the drive end of each cylinder. One end of the buffer spring is fixedly connected to one side of the housing, and the other end of the buffer spring is fixedly connected to one side of the positioning block.

[0021] Through the above technical solution, the buffer spring sleeved on the outside of the cylinder provides the necessary elastic support when the cylinder is working, which can effectively buffer the impact force and prevent vibration or displacement during the cutting process. The driving end of the cylinder is connected to a positioning block, which can move in a fixed direction under the push of the cylinder, thereby firmly clamping the steel plate and keeping its position stable.

[0022] As a further description of the above technical solution:

[0023] The installation mechanism includes two housings, which are respectively fixedly connected to both sides of the connecting plate. A return spring is fixedly connected to the inner wall of the housing, and a locking block is fixedly connected to the other end of the return spring. Fixed posts are fixedly connected to both sides of the bottom of the connecting plate. A return spring is fixedly connected to the inner wall of the fixed post, and a locking block is fixedly connected to the bottom of the return spring.

[0024] Through the above technical solution, two housings are fixedly connected to both sides of the connecting plate, providing reliable support for the cutting plate. A return spring is fixedly connected to the inner wall of the housing. Once the cutting plate is installed or needs to be disassembled, the return spring will provide the necessary elastic support, thereby achieving safe locking of the cutting plate. In addition, a locking block is connected to one end of the return spring to further prevent accidental detachment during the cutting process. The fixing posts on both sides of the bottom of the connecting plate provide additional stability. The return spring two fixedly connected to its inner wall can adapt to the installation requirements of the cutting plate. The bottom of the return spring two is connected to the locking block two, which cooperates with the locking block one to ensure that the structure remains compact and stable during the installation of the cutting plate.

[0025] As a further description of the above technical solution:

[0026] The limiting mechanism includes two limiting posts, the outer side of which is fixedly connected to the inner wall of the housing, the through hole of the movable plate is slidably connected to the outer side of the limiting posts, and the top two sides of the support plate are fixedly connected to limiting rods, the outer side of which is slidably connected to the inner wall of the movable plate.

[0027] The above technical solution ensures the stability of the moving plate during operation and prevents excessive movement. Two limiting posts are fixedly connected to the inner wall of the housing to support the moving plate. The through hole of the moving plate is slidably connected to the outside of the limiting posts, allowing the moving plate to move smoothly and accurately under the guidance of the limiting posts. In addition, the limiting rods fixedly connected to the top two sides of the support plate provide additional guiding effect. The outside of the limiting rods is slidably connected to the inner wall of the moving plate, enhancing the stability of the structure. This design ensures that the moving plate can maintain its position during the cutting process, avoiding cutting errors caused by instability or misoperation.

[0028] As a further description of the above technical solution:

[0029] The outer side of the first locking block engages with the inner wall of the cutting plate, and the outer side of the second locking block engages with the top groove of the first locking block.

[0030] Through the above technical solution, the outer side of the first locking block engages with the inner wall of the cutting plate, ensuring a firm connection of the cutting plate after installation and preventing loosening or displacement during the cutting operation, thereby improving cutting accuracy and work safety. At the same time, the outer side of the second locking block engages with the top groove of the first locking block, further increasing the stability and shear resistance of the entire component.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, the combination of the support platform and the moving platform ensures the stable positioning of the steel plate; the moving platform is driven by a motor, which enables the lower blade to be precisely adjusted in position. The motor drives the screw to rotate and guide the moving plate, thereby pushing the hydraulic cylinder and tilting mechanism to achieve effective adjustment of the cutting plate. The meshing design of the worm gear and worm wheel allows the connecting plate to rotate smoothly, optimizes the cutting angle, reduces friction between the tool and the material, reduces wear, improves processing efficiency, ensures smooth cutting edges, and meets the shearing requirements of steel plates of different thicknesses.

[0033] 2. In this utility model, the starting cylinder drives the positioning block to move and clamp the steel plate, ensuring its stability. Subsequently, the hydraulic cylinder pushes the support plate, causing the connecting plate to drive the cutting plate to cut the steel plate. When disassembling the cutting plate, push the second locking block to disengage it from the inner wall of the first locking block. When the first locking block is pressed, the return spring will be pushed into the housing to release the cutting plate. During installation, the return spring releases its elastic potential energy to engage the cutting plate, and the second return spring pushes the second locking block to engage the first locking block, enhancing the connection stability. This design ensures the quick replacement and safe fixation of the cutting plate. Attached Figure Description

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.

A motor 23 is fixedly connected to one side of the lead screw 22. The motor 23 can provide power, making the entire adjustment mechanism work more efficiently. The moving table 24 is threadedly connected to the outside of the lead screw 22. The flexible movement of the moving table 24 allows the lower blade 25 to effectively perform steel plate cutting operations, improving cutting efficiency. The lower blade 25 is installed on one side of the moving table 24. When the moving table 24 moves, the lower blade 25 will also move accordingly to accurately complete the cutting task.

[0045] A support platform 26 is fixedly connected to the top of the moving table 24. The support platform 26 ensures the stability of the processed material during processing and avoids cutting errors caused by vibration. A moving component 27 is installed on the inner wall of the housing 1. The design of the moving component 27 allows the internal structures to be adjusted quickly and in coordination.

The top of the slider 282 is fixedly connected to the bottom of the moving table 24 to ensure a firm connection between the two and provide support for the entire movement process.

[0047] Specifically, the steel plate to be processed is first placed on top of the support platform 26. Then, motor 1 23 is started. The operation of the motor drives the moving platform 24 to move through the lead screw 22, thereby adjusting the position of the lower blade 25 to achieve precise cutting. Next, motor 271 is started. The motor drives the screw 272 to rotate, which drives the moving plate 273 to move. This allows for further adjustment of the position of the hydraulic cylinder 274 to enhance the force support required during the cutting process. At the same time, through the tilting mechanism 3, the support plate 275 can adjust the angle of the cutting plate 277 as needed to achieve cutting effects for different processing requirements.

[0048] refer to Figure 4 and Figure 5 The tilting mechanism 3 includes two extension plates 31. The top of the extension plates 31 is fixedly connected to the bottom of the support plate 275, which enhances the connection strength between the support plate 275 and the tilting mechanism 3. A worm gear 32 is fixedly connected to the adjacent side of the two extension plates 31. The design of the worm gear 32 facilitates connection with the worm 35 to achieve more precise motion conversion. A rotating plate 33 is rotatably connected to the distant side of the two extension plates 31. The design of the rotating plate 33 allows the cutting angle to be quickly adjusted, flexibly meeting the cutting needs of steel plates of different thicknesses and materials. A motor 34 is fixedly connected to the outside of the rotating plate 33. The efficient operation of the motor 34 ensures that the system can complete the oblique cutting action in a short time. A worm 35 is fixedly connected to the drive end of the motor 34. The worm 35 and the worm gear 32 are meshed, which can reliably transmit rotational power and ensure the stable operation of the tilting mechanism 3.

[0049] refer to Figure 3 The positioning mechanism 4 includes multiple cylinders 41. The top of the cylinder 41 is fixedly connected to one side of the housing 1. The setting of the cylinder 41 ensures that the steel plate can remain stable during cutting, effectively eliminating cutting errors. A buffer spring 42 is sleeved on the outside of the cylinder 41. The design of the spring can effectively buffer when the cylinder 41 is working and apply uniform pressure to the steel plate. A positioning block 43 is fixedly connected to the drive end of the cylinder 41. The positioning block 43 can move in a fixed direction under the push of the cylinder 41 to firmly clamp the steel plate. One end of the buffer spring 42 is fixedly connected to one side of the housing 1 to provide necessary elastic support to adapt to different cutting requirements. The other end of the buffer spring 42 is fixedly connected to one side of the positioning block 43 to ensure that the positioning block 43 returns to its position quickly when the cylinder 41 retracts.

[0050] Specifically, the tilting mechanism 3 is connected to the support plate 275 via two extension plates 31, allowing the cutting plate 277 to quickly adjust its angle to adapt to the cutting needs of steel plates of different thicknesses and materials. The meshing connection between the worm gear 32 and the worm 35 enables efficient motion conversion and ensures stable transmission of rotational power. After the motor 34 is started, the worm 35 at its drive end will drive the worm gear 32 to rotate, thereby causing the rotating plate 33 to be adjusted accordingly to meet the precision requirements of cutting. The positioning mechanism 4 consists of multiple cylinders 41, which are installed on one side of the housing 1 to ensure that the steel plate remains stable during the cutting process and avoid cutting errors caused by displacement. When the cylinder 41 works, the external buffer spring 42 will effectively apply uniform pressure to the steel plate to ensure the stability of the steel plate during the cutting process. The drive end of the cylinder 41 is connected to a positioning block 43, which can firmly clamp the steel plate by pushing the cylinder 41, thereby ensuring the accuracy of cutting.

[0051] refer to Figure 3 and Figure 6 The mounting mechanism 5 includes two housings 51, which are fixedly connected to both sides of the connecting plate 276. The design of the housings 51 provides stable installation conditions for the cutting plate 277. A return spring 52 is fixedly connected to the inner wall of the housing 51. The return spring 52 provides necessary elastic support when the cutting plate 277 is installed or removed, achieving safe locking of the cutting plate 277. A locking block 53 is fixedly connected to the other end of the return spring 52. The locking block 53 ensures the stability of the cutting plate 277 and prevents accidental detachment during the cutting process. The connecting plate 276... Fixed posts 54 are fixedly connected to both sides of the bottom of 6. The fixed posts 54 provide lateral guidance to ensure a stable connection between the connecting plate 276 and the housing 51. The inner wall of the fixed posts 54 is fixedly connected to the second return spring 55. The design of the second return spring 55 allows the flexible insertion of the second locking block 56, which simplifies the installation process of the cutting plate 277. The bottom of the second return spring 55 is fixedly connected to the second locking block 56. The outside of the second locking block 56 engages with the top groove of the first locking block 53 to ensure the compactness and stability of the structure during the installation of the cutting plate 277 and improve the reliability of the system.

[0052] The limiting mechanism 7 includes two limiting posts 71. The limiting posts 71 are fixedly connected to the inner wall of the housing 1. The function of the limiting posts 71 in the whole device is to fix the moving plate 273 and prevent excessive movement during operation. The through hole of the moving plate 273 is slidably connected to the outside of the limiting posts 71 to ensure that the movement of the moving plate 273 is stable and does not deviate. The top two sides of the support plate 275 are fixedly connected to limiting rods 72. The setting of the limiting rods 72 further enhances the stability of the entire cutting system. The outside of the limiting rods 72 is slidably connected to the inner wall of the moving plate 273. This design ensures that the entire structure can operate efficiently and stably.

[0053] Specifically, the installation mechanism 5 provides stable and safe installation conditions for the cutting plate 277 through two housings 51. A return spring 52 is fixedly connected to the inner wall of each housing 51. This spring provides necessary elastic support when the cutting plate 277 is installed or removed, ensuring that the cutting plate 277 can be securely locked. A locking block 53 connected to the return spring 52 further prevents the cutting plate 277 from accidentally falling off during operation. The bottom of the connecting plate 276 is fixedly connected to a fixing post 54. These fixing posts 54 provide lateral guidance between the housings 51 and the connecting plate 276, enhancing structural stability. At the same time, a return spring 55 fixedly connected to the inner wall of the fixing post 54 allows the locking block 56 to be inserted flexibly, simplifying the assembly process of the cutting plate 277 and ensuring the compactness and stability of the structure during installation. The design of the limiting mechanism 7 ensures the stability of the entire device. Two limiting posts 71 are fixed to the inner wall of the housing 1, providing a stable guide for the moving plate 273. The moving plate 273 can move smoothly under the guidance of the limiting posts 71, avoiding deviations during operation.

[0054] Working principle: When the equipment is needed, the steel plate to be processed is placed on top of the support platform 26. Then, motor 23 is started, which drives the moving platform 24 to rotate. This rotation of the moving platform 24 moves its position, causing the lower blade 25 to move for adjustment. Simultaneously, motor 271 is started, driving the screw 272 to rotate. The rotation of the screw 272 then moves the moving plate 273. The movement of 273 drives the hydraulic cylinder 274, which in turn drives the support plate 275 to drive the tilting mechanism 3, ultimately causing the cutting plate 277 to move for further adjustment. The starting motor 34 drives the worm gear 35 to rotate. At this time, the rotation of the worm gear 35 can follow the groove of the worm wheel 32, thereby controlling the rotation of the connecting plate 276, which in turn drives the cutting plate 277 to rotate. This allows for angle adjustment, improving the contact method during cutting, reducing friction between the tool and the material, resulting in a smoother cutting edge and reducing the formation of burrs and cracks.

[0055] During cutting, cylinder 41 is activated to move positioning block 43 to clamp the steel plate, keeping it stable. Then, hydraulic cylinder 274 is activated to move support plate 275, causing connecting plate 276 to move cutting plate 277 to cut the steel plate. When cutting plate 277 needs to be disassembled, push block 2 56 to disengage it from the inner wall of block 1 53. Then, press block 1 53. Pressing block 1 53 will push return spring 1 52 and retract it into the inner wall of housing 51, thus disassembling cutting plate 277. During installation, return spring 1 52 releases elastic potential energy to engage cutting plate 277 with block 1 53. Then, return spring 2 55 pushes block 2 56 to engage block 1 53, restricting block 1 53 and achieving connection. This stabilizes block 1 53 and improves connection stability.
