Description

Technical Field

[0001] This utility model relates to the field of metallurgical shearing technology, specifically a quick-change metallurgical shearing blade. Background Technology

[0002] Shear blades are one type of shearing tool. They are mainly driven by a hydraulic mechanism to cut pipes or wires, thereby achieving the length processing of pipes or wires. Metallurgical shear blades are also a type of shear blade.

[0003] In response, Chinese patent application publication number CN210907625U discloses a fixed shear blade with a lower blade buffer device, including a base, a lower grooved blade die, an upper convex pressing blade die, an upper convex pressing blade die guide post, a lower grooved blade die guide groove, a buffer module, and a spring compression post. The buffer module is disposed on both sides of the groove of the lower grooved blade die, and the upper convex pressing blade die guide posts are disposed on both sides of the lower end of the upper convex pressing blade die. The bottom of the upper convex pressing blade die guide posts is attached to the spring contact plate of the buffer module. When the upper convex pressing blade die is pressed down, the spring is compressed by the spring contact plate, and the spring buffers the upper convex pressing blade die. This utility model of a fixed shear blade with a lower blade buffer device avoids the blade surface of the upper convex pressing blade die from directly contacting the bottom of the lower grooved blade die, thereby extending the service life of the upper convex pressing blade die.

[0004] However, in actual use, most metallurgical shear blades are installed and fixed with bolts. But when fixed with bolts, it is inconvenient to quickly replace the metallurgical shear blades later, and the installation of metallurgical shear blades requires a certain degree of stability. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-change metallurgical shear blade to solve the problems mentioned in the background art, where most metallurgical shear blades are installed and fixed by bolts, which makes it inconvenient to quickly replace the metallurgical shear blades later, and also requires a certain degree of stability during the installation of the metallurgical shear blades.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-change metallurgical shear blade, comprising a mounting frame, wherein a mounting groove is provided inside the mounting frame, a metallurgical shear blade body is installed inside the mounting groove, and sliders are installed on both the front and rear surfaces of the metallurgical shear blade body; a sliding groove is provided on the inner sidewall of the mounting frame, and the sliding groove and the slider are mutually adapted.

[0007] A top frame is installed on the top surface of the mounting frame. A spring body is installed at the lower end of the top frame, penetrating the top surface of the mounting frame. A fastening plate is installed at the end of the spring body away from the top frame.

[0008] Preferably, the lower surface of the fastening plate abuts against the upper surface of the metallurgical shear blade body, and a telescopic cylinder is installed on the top surface of the fastening plate.

[0009] Preferably, the end of the telescopic cylinder away from the fastening plate is connected to the lower surface of the top frame, and both the telescopic cylinder and the spring body are provided with two sets.

[0010] Preferably, a side frame is mounted on the back of the mounting frame, and a hydraulic cylinder is mounted on the top surface of the side frame.

[0011] Preferably, a connecting frame is installed at the end of the hydraulic cylinder away from the side frame.

[0012] Preferably, the upper surface of the mounting frame is provided with a slot, the slot is provided with an insert block, and the top surface of the insert block is provided with a top block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This quick-change metallurgical shear blade, through its mounting frame, shear blade body, slider, slide groove, top frame, spring body, fastening plate, telescopic cylinder, side frame, hydraulic cylinder, connecting frame, and mounting slot, allows for rapid installation. First, the shear blade body is installed entirely into the mounting slot, and then the slider slides into the slide groove. The overall sliding installation is fast. Simultaneously, when the shear blade body slides into the mounting slot, the lower surface of the fastening plate abuts against the top surface of the shear blade body, compressing the spring body. The telescopic cylinder limits the spring body's position, ensuring stable contact between the fastening plate and the upper surface of the shear blade body. The overall installation of the shear blade body is stable. Subsequent replacement of the shear blade body is simple: just slide it out of the mounting slot. This rapid replacement demonstrates the practicality of the design.

[0015] 2. This quick-change metallurgical shear blade, through its slots, insert blocks, and top block, allows for stable contact when the shear blade body is installed into the mounting slot. The insert block, with its lower surface against the upper surface of the shear blade body, and the top block, with its lower surface against the upper surface of the mounting frame, provides additional stability. The two slots also limit the position of the shear blade body. Finally, by activating the hydraulic cylinder, the side frame moves downwards, enabling the shear blade body to perform the cutting operation, demonstrating the design's functionality.

[0021] 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.

[0022] Please see Figures 1-4 One embodiment provided by this utility model:

[0023] A quick-changeable metallurgical shear blade is disclosed in this application. The metallurgical shear blade body 2, spring body 6, hydraulic cylinder 10, and top block 15 used in this application are all commercially available products. Their principles and connection methods are well-known prior art and will not be described in detail here. The blade includes a mounting frame 1 with an internal mounting groove 12. The metallurgical shear blade body 2 is mounted inside the mounting groove 12. Slider blocks 3 are mounted on both the front and rear surfaces of the metallurgical shear blade body 2. A sliding groove 4 is provided on the inner side wall of the mounting frame 1, and the sliding groove 4 and the slider 3 are mutually compatible. A side frame 9 is mounted on the back of the mounting frame 1, and a hydraulic cylinder 10 is mounted on the top surface of the side frame 9. The end of the hydraulic cylinder 10 furthest from the side frame 9... A connecting frame 11 is installed, and a slot 13 is opened on the upper surface of the mounting frame 1. A plug 14 is installed inside the slot 13, and a top block 15 is installed on the top surface of the plug 14. When the metallurgical shear blade body 2 is installed into the mounting slot 12, the plug 14 is inserted into the slot 13, so that the lower surface of the plug 14 will also abut against the upper surface of the metallurgical shear blade body 2. Then, the lower surface of the top block 15 abuts against the upper surface of the mounting frame 1. The overall abutment is relatively stable. Thus, the position of the metallurgical shear blade body 2 can be limited by the design of the two sets of slots 13. Finally, by starting the hydraulic cylinder 10, the side frame 9 is driven to move downward, which can drive the metallurgical shear blade body 2 to perform the shearing operation.

[0024] Top frame 5 is installed on the top surface of mounting frame 1. A spring body 6 is installed at the lower end of top frame 5, penetrating the top surface of mounting frame 1. A fastening plate 7 is installed at the end of spring body 6 away from top frame 5. The lower surface of fastening plate 7 abuts against the upper surface of metallurgical shear blade body 2. A telescopic cylinder 8 is installed on the top surface of fastening plate 7. The end of telescopic cylinder 8 away from fastening plate 7 is connected to the lower surface of top frame 5. Two sets of telescopic cylinder 8 and spring body 6 are provided. During installation, the metallurgical shear blade body 2 is first installed entirely into mounting groove 12, and the slider 3 is slidably installed into sliding groove 4. The overall sliding installation speed... The installation is relatively fast. When the metallurgical shear blade body 2 slides into the mounting groove 12, the lower surface of the fastening plate 7 will abut against the top surface of the metallurgical shear blade body 2. At this time, the spring body 6 begins to be compressed. The telescopic cylinder 8 limits the spring body 6, so that the fastening plate 7 can stably abut against the upper surface of the metallurgical shear blade body 2. The overall abutment is relatively stable, and the metallurgical shear blade body 2 is relatively stable during installation. When replacing the metallurgical shear blade body 2, it is only necessary to slide the metallurgical shear blade body 2 out of the mounting groove 12, so that the metallurgical shear blade body 2 can be replaced quickly.

[0025] Working Principle: During installation, the metallurgical shear blade body 2 is first installed into the mounting groove 12, and the slider 3 is slidably installed into the sliding groove 4. The overall sliding installation speed is relatively fast. Simultaneously, when the metallurgical shear blade body 2 slides into the mounting groove 12, the lower surface of the fastening plate 7 abuts against the top surface of the metallurgical shear blade body 2. At this time, the spring body 6 begins to compress. The telescopic cylinder 8 limits the spring body 6, allowing the fastening plate 7 to stably abut against the upper surface of the metallurgical shear blade body 2. The overall contact is relatively stable, and the metallurgical shear blade body 2 is relatively stable during installation. Subsequent replacement of the metallurgical shear blade body 2... When the metallurgical shear blade body 2 is installed in the mounting slot 12, the insert block 14 is inserted into the slot 13. The lower surface of the insert block 14 will abut against the upper surface of the metallurgical shear blade body 2, and the lower surface of the top block 15 will abut against the upper surface of the mounting frame 1. The overall abutment is relatively stable. The design of the two sets of slots 13 can also limit the position of the metallurgical shear blade body 2. Finally, by starting the hydraulic cylinder 10, the side frame 9 is driven to move downward, which can drive the metallurgical shear blade body 2 to perform the shearing operation. The above is the working principle of this utility model.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
