Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a cutting device for processing metal forgings. Background Technology

[0002] Existing metal forging cutting equipment is mainly used to cut large metal billets into smaller pieces suitable for subsequent forging processes, preparing for the forging of parts of different specifications, making the billet size more compatible with the size and shape of the final product, and improving material utilization and forging efficiency.

[0003] However, it lacks a mechanism for adjusting the pressing force during use. It cannot be adjusted to a suitable and stable pressing force during the cutting process. The forging may shake or shift due to insufficient force, resulting in a large deviation between the cut dimensions and the design dimensions. This fails to meet the requirements of high-precision machining. Furthermore, the vibration generated during cutting cannot be effectively buffered and damped, which will cause unevenness on the cut surface and affect the appearance quality of the forging. Summary of the Invention

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a cutting device for processing metal forgings. When cutting, the lifting plate is driven down together, so that the pressing plate presses against the surface of the metal forging. During the pressing process, the spring and damper are compressed. The spring and damper play a buffering and shock absorption role during the pressing process, which can effectively reduce the vibration and shaking of the metal forging during cutting. The stable pressing force can make the cutting process more stable, avoid the cutting size deviation or uneven cutting surface caused by vibration, thereby improving the cutting accuracy. The height of the spring and damper can be adjusted by rotating the screw, so as to control the degree of compression during descent, thereby controlling the pressing force. Different thicknesses of metal forgings require different pressing forces. By adjusting the height of the spring and damper to control the pressing force, the stability of cutting can be guaranteed when cutting metal forgings of different thicknesses.

[0012] According to the present invention, a cutting device for processing metal forgings has a support leg fixedly connected to the lower surface of the base plate, and a reinforcing rod fixedly connected between the support legs.

[0013] Compared with existing technologies, this metal forging cutting device lowers the lifting plate during cutting, causing the pressing plate to press against the surface of the metal forging. During the pressing process, the spring and damper are compressed, acting as a buffer and shock absorber to effectively reduce vibration and shaking of the metal forging during cutting.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a cutting device for processing metal forgings, which includes: a base plate 5, a through groove 4 on the base plate 5, a plurality of conveying rollers 3 rotatably connected to the inner surface of the through groove 4, a support leg 6 fixedly connected to the lower surface of the base plate 5, and a reinforcing rod 7 fixedly connected between the support legs 6.

[0023] Specifically, a through groove 4 is provided on the base plate 5, and multiple conveying rollers 3 are rotatably connected within the through groove 4. When it is necessary to process the metal forging, the metal forging is placed on the conveying rollers 3. Since the conveying rollers 3 can rotate freely, the metal forging can be moved along the conveying direction on the conveying rollers 3 by external force and manual pushing, thereby conveying the forging to the cutting position for convenient subsequent cutting operations.

[0024] A bracket 10 is fixedly connected to the upper surface of the base plate 5. Two sliding grooves 20 are provided on the bracket 10. A slider 17 is slidably connected to the inner surface of each of the two sliding grooves 20. A connecting rod 16 is fixedly connected to the upper surface of the slider 17. A hydraulic rod 2 is fixedly connected to the lower surface of the bracket 10. The lower end of the hydraulic rod 2 is fixedly connected to the upper surface of the connecting rod 16. A hydraulic cylinder 1 is fixedly connected to the upper surface of the bracket 10. The hydraulic rod 2 is driven by the hydraulic cylinder 1.

[0025] Specifically: The support 10 is provided with two sliding grooves 20. The slider 17 slides in the sliding groove 20. The hydraulic cylinder 1 on the upper surface of the support 10 drives the hydraulic rod 2 to extend and retract. The lower end of the hydraulic rod 2 is fixedly connected to the connecting rod 16, and the connecting rod 16 is fixedly connected to the slider 17. Therefore, when the hydraulic cylinder 1 drives the hydraulic rod 2 to descend or ascend, it will drive the connecting rod 16 and the slider 17 to slide vertically in the sliding groove 20, thereby causing the slide rail 18 connected between the two sliders 17 to move vertically as a whole, realizing the ascent and descent of the cutting device.

[0026] A slide rail 18 is fixedly connected between two sliders 17. A slider 19 is slidably connected to the inner surface of the slide rail 18. A lead screw 22 is rotatably connected to the inner surface of the slide rail 18. The lead screw 22 is threadedly connected to the slider 19. A motor 21 is fixedly connected to the inner surface of the slide rail 18. The lead screw 22 is driven by the motor 21.

[0027] Specifically, a second slider 19 is slidably connected to the inner surface of the slide rail 18, and a lead screw 22 is rotatably connected inside the slide rail 18. The lead screw 22 is threadedly connected to the second slider 19, and the lead screw 22 is driven by a second motor 21. When the second motor 21 starts, it will drive the lead screw 22 to rotate. Due to the threaded engagement between the lead screw 22 and the second slider 19, the rotation of the lead screw 22 will cause the second slider 19 to slide horizontally inside the slide rail 18, thereby driving the support frame 26 and the blade 27 fixed on the lower surface of the second slider 19 to move horizontally, realizing the blade translational cutting.

[0028] A support frame 26 is fixedly connected to the lower surface of slider 2 19. A blade 27 is rotatably connected to the inner surface of the support frame 26. A motor 28 is fixedly connected to the side surface of the support frame 26. The blade 27 is driven by the motor 28.

[0029] Specifically, the inner surface of the support frame 26 is rotatably connected to the blade 27, and the motor 28 on the side surface of the support frame 26 is connected to the blade 27. When the motor 28 is started, it will drive the blade 27 to rotate at high speed. Combined with the vertical and horizontal position movement mentioned above, the rotating blade 27 reaches the cutting position of the metal forging and performs the cutting operation on the metal forging.

[0030] A lifting plate 8 is fixedly connected to the side surface of the slide rail 18, a slide rod 11 is fixedly connected to the upper surface of the base plate 5, a limiting sleeve 12 is fixedly connected to the side surface of the lifting plate 8, the limiting sleeve 12 is slidably connected to the outer wall of the slide rod 11, a plurality of sleeves 13 are connected through the inner surface of the lifting plate 8, a sliding block 25 is slidably connected to the inner surface of the sleeve 13, a spring 15 is fixedly connected to the lower surface of the sliding block 25, a damper 14 is fixedly connected to the lower surface of the sliding block 25, a pressing plate 9 is fixedly connected to the lower end of the spring 15 and the damper 14, a connecting frame 24 is fixedly connected to the upper surface of the sliding block 25, and a screw 23 is rotatably connected to the upper surface of the lifting plate 8, the screw 23 is threadedly connected to the connecting frame 24.

[0031] Specifically: During the cutting process, when the hydraulic cylinder 1 drives the hydraulic rod 2 to descend, causing the slide rail 18 to descend, the lifting plate 8 fixed to the side surface of the slide rail 18 will also descend accordingly. The lifting plate 8 is connected to the pressing plate 9 through the sleeve 13 and the sliding block 25. When the lifting plate 8 descends, the pressing plate 9 will press against the surface of the metal forging. During the pressing process, the spring 15 and the damper 14 will be compressed. The spring 15 and the damper 14 play a role in buffering and shock absorption, reducing the vibration and shaking generated during cutting, and ensuring the stability of the cutting process. The upper surface of the lifting plate 8 A screw 23 is rotatably connected to a connecting frame 24 connected to the upper surface of the sliding block 25. By rotating the screw 23, due to the threaded engagement between the screw 23 and the connecting frame 24, the connecting frame 24 will cause the sliding block 25 to slide up and down within the sleeve 13, thereby adjusting the initial height of the spring 15 and the damper 14. This allows control over the degree to which the spring 15 and the damper 14 are compressed when the cutting device descends, thereby controlling the pressing force of the pressing plate 9 on the metal forging to meet the cutting requirements of metal forgings of different thicknesses and materials.

[0032] Working principle: In use, the metal forging to be cut is placed on the conveyor roller 3. The position of the metal forging can be easily adjusted by the conveyor roller 3 to place it in a suitable cutting area. According to the thickness and material characteristics of the metal forging, the screw 23 is rotated. The screw 23 is threadedly connected to the connecting frame 24, thereby driving the sliding block 25 to move up and down within the sleeve 13. This adjusts the height of the spring 15 and the damper 14, thus setting a suitable pressing force. The motor 21 is started, which drives the lead screw 22 to rotate. Since the lead screw 22 is threadedly connected to the slider 19, the slider 19 will move laterally on the slide rail 18, thereby driving the support frame 2. 6. The blade 27 moves above the starting position where the metal forging needs to be cut, completing the lateral positioning. The hydraulic cylinder 1 is activated, and the hydraulic cylinder 1 drives the hydraulic rod 2 to move downward. The hydraulic rod 2 drives the connecting rod 16 and the connected slider 17 to slide downward in the slide groove 20, thereby causing the slide rail 18, lifting plate 8, etc. to move downward as a whole. During the descent, the pressing plate 9 first contacts the surface of the metal forging. As it continues to descend, the spring 15 and damper 14 are compressed, applying a stable pressing force to the metal forging. When the blade 27 descends to contact the metal forging, the motor 28 is activated. The motor 28 drives the blade 27 to rotate, and the cutting of the metal forging begins.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
