Description

Technical Field

[0001] This utility model relates to the field of shear blade processing technology, and in particular to a clamping device for shear blade processing. Background Technology

[0002] Metallurgical shear blades are key and easily damaged components used in the metallurgical industry for shearing metal materials. They are usually installed on shearing machines and are widely used in hot rolling and cold rolling production lines and shearing processing centers in steel plants. During the production and processing process, shear blades need to be clamped and fixed using clamping devices.

[0003] For example, patent number CN219464912U discloses a clamping device for cutting shear blades, including a tool holder. The top surface of the tool holder has a placement groove, and a shear blade extending to the top of the tool holder is placed inside the placement groove. The tool holder has two connecting grooves, and an electric push rod is fixedly installed inside each of the two connecting grooves. The output ends of the two electric push rods are fixedly connected to support plates. A connecting rod with one end penetrating the connecting groove and extending into the placement groove is fixedly connected to the opposite side of each of the two support plates. A clamping plate is fixedly connected to the opposite side of each of the two connecting rods, and a rubber pad is fixedly connected to the opposite side of each of the two clamping plates.

[0004] For example, patent number CN221792279U discloses a clamp for processing paired metallurgical shear blades, including a base, a fixed seat fixedly connected to the top of the base, and clamping mechanisms provided on both the front and back of the top of the base. The clamping mechanism includes a support plate, and pull rods pass through both sides of the front of the support plate, with a clamping plate fixedly connected to one end of the pull rods extending to the outside of the support plate. This utility model relates to the field of metallurgical shear blade processing technology.

[0005] While existing clamping devices for shear blade processing can clamp and fix shear blades of different thicknesses by setting up clamping structures on both sides, their structural design lacks effective support and auxiliary positioning for the bottom of the shear blade, resulting in poor adaptability to shear blades of different heights. At the same time, the device's drainage filtration structure is easily blocked by metal debris generated during processing, affecting drainage efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a clamping device for shear blade processing. This solves the problems of existing clamping devices for shear blade processing lacking effective support and auxiliary positioning for the bottom of the shear blade, resulting in poor adaptability to shear blades of different heights and specifications, and the device's drainage and filtration structure being easily clogged by metal debris generated during processing, affecting drainage efficiency.

[0007] The technical solution of this utility model is as follows: a clamping device for shear blade processing, including a base, a drain chamber fixedly installed at the upper end of the base, a drain pipe connected to the lower side of the drain chamber, support frames fixedly installed on the front and rear sides of the drain chamber, a clamping plate provided at the upper end of the support frame, a lifting frame provided inside the drain chamber, filter plates provided on the front and rear sides of the lifting frame, a support plate provided at the lower end of the lifting frame, an electric telescopic rod provided at the lower end of the support plate, slots opened on the left and right sides of the drain chamber, guide plates provided on the sides of the slots, a cleaning frame provided at the upper end of the drain chamber, a cleaning brush one and a cleaning brush two provided at the lower end of the cleaning frame, a handle fixedly installed at the upper end of the cleaning frame, and limit blocks fixedly installed on the front and rear sides of the cleaning frame.

[0008] Preferably, there are two support frames arranged symmetrically front and back, with the clamping plate located on the side of the two support frames that are close to each other, and an electric push rod for driving the clamping plate to move is fixedly installed on the side of the two support frames that are far apart from each other.

[0009] Preferably, the lifting frame has a U-shaped structure design, and the left and right ends of the lifting frame slide against the inner wall of the drainage chamber.

[0010] Preferably, the filter plates are arranged symmetrically about the lifting frame and are fixedly connected to the lifting frame, with the sides of the filter plates slidingly attached to the inner wall of the drainage chamber.

[0011] Preferably, the lower ends of the pallet and the lifting frame are adapted to each other, the lower end of the electric telescopic rod is fixedly connected to the bottom of the drainage chamber, and the output end of the electric telescopic rod is fixedly connected to the lower end of the pallet.

[0012] Preferably, the guide plate is symmetrically arranged on the left and right and is fixedly connected to the outside of the drain chamber, and the limiting block is designed with an L-shaped structure and slides against the drain chamber and the upper side of the guide plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. The clamping device for shear blade processing drives the pallet to rise and fall via an electric telescopic rod, which in turn moves the entire lifting frame up and down to adjust its height to accommodate the clamping requirements of different shear blade specifications. This improves the clamping compatibility and positioning stability of different shear blade specifications. By integrating the filter plate onto the lifting frame, when the filter plate needs maintenance or replacement, the lifting frame can be lifted directly to remove the filter plate from the drain chamber, making disassembly and assembly convenient.

[0016] 2. This clamping device for shear blade processing can remove and discharge solid waste such as metal shavings accumulated on the surface in a timely manner without disassembling the filter plate by lifting the lifting frame and the filter plate to a position where the upper surface of the filter plate is flush with the lower edge of the groove. The cleaning frame can be driven by the handle to reciprocate the cleaning action. The operation is simple and greatly reduces the maintenance difficulty and downtime.

[0017] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-5This utility model provides an embodiment: a clamping device for shear blade processing, including a base 1, a drain chamber 2 fixedly installed on the upper end of the base 1, a drain pipe 201 connected to the lower side of the drain chamber 2, a support frame 3 fixedly installed on the front and rear sides of the drain chamber 2, a clamping plate 4 provided on the upper end of the support frame 3, a lifting frame 5 provided on the inner side of the drain chamber 2, filter plates 6 provided on the front and rear sides of the lifting frame 5, a support plate 7 provided on the lower end of the lifting frame 5, an electric telescopic rod 8 provided on the lower end of the support plate 7, slots 9 opened on the left and right sides of the drain chamber 2, a guide plate 901 provided on the side of the slots 9, a cleaning frame 10 provided on the upper end of the drain chamber 2, a first cleaning brush 11 and a second cleaning brush 12 provided on the lower end of the cleaning frame 10, a handle 13 fixedly installed on the upper end of the cleaning frame 10, and limit blocks 14 fixedly installed on the front and rear sides of the cleaning frame 10.

[0026] Please see Figures 1-4 In this embodiment, there are two support frames 3 arranged symmetrically front and back. The clamping plate 4 is located on the side of the two support frames 3 that is close to each other. An electric push rod 401 for driving the clamping plate 4 to move is fixedly installed on the side of the two support frames 3 that is far from each other. The lifting frame 5 has a U-shaped structure design. The left and right ends of the lifting frame 5 slide against the inner wall of the drainage chamber 2. The filter plate 6 is arranged symmetrically front and back about the lifting frame 5 and is fixedly connected to the lifting frame 5. The side of the filter plate 6 slides against the inner wall of the drainage chamber 2. The tray 7 is adapted to the lower end of the lifting frame 5. The lower end of the electric telescopic rod 8 is fixedly connected to the bottom of the drainage chamber 2. The output end of the electric telescopic rod 8 is fixedly connected to the lower end of the tray 7. The shear blade to be processed is placed on the upper end of the lifting frame 5. The tray 7 is driven to rise and fall by the electric telescopic rod 8, which drives the lifting frame 5 to move up and down as a whole, thereby adjusting its height to adapt to the clamping requirements of different specifications of shear blades. Then the electric push rod 401 is activated to push the clamping plates 4 on both sides to firmly clamp the shear blade.

[0027] Please see Figures 2-5In this embodiment, the guide plate 901 is symmetrically arranged from left to right and is fixedly connected to the outer side of the drain chamber 2. The limiting block 14 has an L-shaped structure and slides against the drain chamber 2 and the upper side of the guide plate 901. The first cleaning brush 11 and the second cleaning brush 12 are both fixedly connected to the lower end of the cleaning frame 10. The outer sides of the cleaning frame 10 and the lifting frame 5 are mutually adapted. The first cleaning brush 11 is mutually adapted to the upper end of the lifting frame 5. The second cleaning brush 12 is symmetrically arranged from front to back and is mutually adapted to the upper end of the filter plate 6. The mixture of coolant and metal waste generated during processing is filtered by the filter plate 6. The liquid portion falls into the drain chamber 2 and is discharged through the drain pipe 201, while the solid waste is trapped on the upper surface of the filter plate 6. When it is necessary to clean the waste, the electric telescopic rod 8 is controlled to rise, raising the lifting frame 5 and the filter plate 6 to a position where the upper surface of the filter plate is flush with the lower edge of the groove 9. By manually pulling the handle 13, the cleaning frame 10 is moved left and right along the upper end of the drain chamber 2, so that the first cleaning brush 11 cleans the upper surface of the lifting frame 5 and the second cleaning brush 12 cleans the upper surface of the filter plate 6, pushing the accumulated waste to the groove 9 and smoothly discharged through the guide plate 901.

[0028] During operation, the shear blade to be processed is placed on the upper end of the lifting frame 5. The electric telescopic rod 8 drives the support plate 7 to rise and fall, causing the entire lifting frame 5 to move up and down, thereby adjusting its height to accommodate the clamping requirements of different shear blade specifications. Then, the electric push rod 401 is activated to push the clamping plates 4 on both sides to firmly clamp the shear blade. The mixture of coolant and metal scrap generated during processing is filtered through the filter plate 6. The liquid part falls into the drain chamber 2 and is discharged through the drain pipe 201, while the solid waste is trapped on the upper surface of the filter plate 6. When it is necessary to clean up the waste, the electric telescopic rod 8 is controlled to move up and down. Lift the lifting frame 5 and filter plate 6 to a position where the upper surface of filter plate 6 is flush with the lower edge of slot 9. Manually pull handle 13 to move the cleaning frame 10 left and right along the upper end of the drain chamber 2, so that cleaning brush 11 cleans the upper surface of the lifting frame 5 and cleaning brush 212 cleans the upper surface of filter plate 6, pushing the accumulated waste to slot 9 and smoothly discharging it through guide plate 901. When the filter plate 6 needs maintenance or replacement, retract the clamping plate 4 to fit against the support frame 3, and then lift it directly from both ends of the lifting frame 5, so that the filter plate 6 slides off along the inner wall of the drain chamber 2, making disassembly and assembly convenient.

[0029] Compared to the previous document, which achieved clamping and fixing of shear blades of different thicknesses through a two-sided clamping structure, the design lacked effective support and auxiliary positioning for the bottom of the shear blade, resulting in poor adaptability to shear blades of different heights. This device uses an electric telescopic rod 8 to drive the support plate 7 to rise and fall, thereby moving the lifting frame 5 up and down to adjust its height and adapt it to the clamping requirements of different shear blade specifications. This improves the clamping compatibility and positioning stability of different shear blade specifications. However, by integrating the filter plate 6 onto the lifting frame 5, maintenance of the filter plate 6 is required. When replacing, simply lift the lifting frame 5 to detach the filter plate 6 from the drain chamber 2. This makes disassembly and assembly convenient. Compared to the drain filter structure in the reference document, which is easily clogged by metal debris generated during processing and affects the drain efficiency, this device lifts the lifting frame 5 and the filter plate 6 to a position where the upper surface of the filter plate is flush with the lower edge of the slot 9. Without disassembling the filter plate 6, the handle 13 drives the cleaning frame 10 to reciprocate and clean the surface-accumulated metal debris and other solid waste in a timely manner. This makes operation simple and greatly reduces maintenance difficulty and downtime.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
