Description

Technical Field

[0001] The utility model relates to the technical field of cold saws, in particular to a saw seat for a section steel cold saw. Background Art

[0002] Steel is a common metal material, which is processed into products with different cross-section shapes by hot rolling or cold rolling. When cutting steel, a cold saw, an efficient cutting tool, is used. Compared with traditional hot saws, cold saws use different cutting technologies, mainly through high-speed rotating saw blades and coolants to achieve cutting, so as to reduce heat and deformation of the cutting area, and improve cutting efficiency and cutting quality. The lower end of the cold saw is equipped with an important component (saw seat). The function of the saw seat is not only to provide a position for the cold saw body to be installed, but more importantly, to provide clamping and fixing for the steel. This clamping and fixing ensures that the steel remains stable during the cutting process.

[0003] The existing cold saw seats for steel sections use two methods to clamp and fix the steel sections: manual fixing or hydraulic rod fixing. Among them, manual fixing can achieve precise clamping of the steel sections compared to hydraulic rod fixing, but its fixing force is affected by human factors and may not be able to apply sufficient fixing force to the steel sections, resulting in the inability to better fix the steel sections when cutting them. When fixing with hydraulic rods, since the clamping widths of each group of steel sections are different, the clamping force needs to be frequently adjusted when the hydraulic rods are used for clamping, which increases the complexity of the operation. Secondly, when clamping and cutting the steel sections, the cut end of the steel sections is in a non-clamped state, which is to reduce the stress concentration in the cutting area, provide a certain range of motion for the steel sections, and reduce the risk of deformation or cracks. However, after the cutting is completed, the steel sections may be affected by the rotational force of the cold saw blade, causing the cut end of the unclamped steel sections to fly out or bounce up, increasing the risk of damage to the cold saw blade.

The upper surface of the slip ring 38 is connected with a metal plate 381 by bolts. The front side of the fixed seat 35 is fixedly connected with the movable plate 4. The front side of the side plate 2 12 is fixedly connected with multiple groups of support columns 2 for limiting the movement of the movable plate 4. The rear side of the side plate 11 is fixedly connected with two groups of hydraulic rods 15. The telescopic end of the hydraulic rod 15 is fixedly connected with the top plate 51. A cutting groove is provided on the right side of the upper surface of the base plate 1 14, the auxiliary plate 6 is fixedly connected to one side of the base plate 1 close to the cutting groove 14, the front side of the upper surface of the auxiliary plate 6 is fixedly connected to the side plate three 61, the rear side of the upper surface of the auxiliary plate 6 is fixedly connected to the side plate four 62, the rear side of the side plate three 61 is fixedly connected to the hydraulic rod two 7, the telescopic end of the hydraulic rod two 7 is fixedly connected to the moving plate 8, the rear side of the moving plate 8 is connected to the elastic clamping plate piece one 9, the front side of the side plate four 62 is connected to the elastic clamping plate piece two 10, the proximity switch 321, the hydraulic rod one 5 and the hydraulic rod two 7 are all electrically connected to the control box.

[0025] The utility model clamps and fixes the steel section by driving the top plate 51 through the hydraulic rod 15. When the movable plate 4 located at the rear side of the steel section receives the thrust from the hydraulic rod 15, the movable plate 4 will move toward the support column 2 until the rear side of the movable plate 4 abuts against the front end of the support column 2, and the movable plate 4 will not be able to move further. At the same time, the movable plate 4 will drive the slip ring 38 to slide on the outside of the cross bar 31 through the connecting seat 32 and the diagonal support 37, and the slip ring 38 drives the metal plate 381 to gradually approach the proximity switch 321 (at this time, the spring 1 33 and the spring 2 36 are gradually compressed). When the movable plate 4 abuts against the support column 2, the metal plate 381 also enters the sensing range of the proximity switch 321 at the same time. The proximity switch 321 transmits a signal to the control box, and the control box controls the hydraulic rod 15 to stop operating. At this time, the steel section is precisely and firmly clamped between the movable plate 4 and the top plate 51.

[0026] Hydraulic rod 27 will operate and stop synchronously with hydraulic rod 15. When hydraulic rod 27 is in operation, its telescopic end drives the movable plate 8 and the elastic clamping plate 19 to move toward the side plate 3 61, and can elastically clamp the steel section between the movable clamping plate 92 and the elastic clamping plate 2 10. When operating the cold saw body to cut the steel section, the end of the steel section located on the auxiliary plate 6 is elastically fixed by the elastic clamping plate 19 and the elastic clamping plate 2 10, providing a certain range of movement for the steel section, which can reduce the stress concentration in the cutting area and reduce the risk of deformation or cracks. At the same time, when the cutting is completed, the elastic clamping plate 19 and the elastic clamping plate 2 10 will elastically clamp the cut end of the steel section to prevent it from bouncing up or flying out.

[0027] When the steel section cutting is completed, the hydraulic rod 1 5 drives the top plate 51 to reset. After the steel section is taken out, the spring 1 33 and the spring 2 36 recover their deformation, thereby driving the slip ring 38 and the movable plate 4 to reset, preparing for the next steel section clamping.

[0028] The structures of the elastic clamping plate member 1 9 and the elastic clamping plate member 2 10 are consistent and are respectively located on both sides of the steel section.

[0029] It should be noted that in order to implement the above solution, it is necessary to ensure that when the rear side of the movable plate 4 is just in contact with the front end of the support column 2, the metal plate 381 just enters the sensing range of the proximity switch 321. (When implementing the above solution, those skilled in the art may first contact the movable plate 4 with the front side of the support column 2, and then adjust the installation position of the proximity switch 321)

[0030] Furthermore, a contact block 21 is fixedly connected to the front side of the support column 2 ; the contact block 21 may be a rubber pad to reduce the wear caused by the direct contact between the support column 2 and the movable plate 4 .

[0031] Furthermore, the outer side of the cross bar 31 is connected with a limit ring 311 by bolts, and the limit ring 311 is arranged between the slip ring 38 and the slide cylinder 3; the limit ring 311 limits the slip ring 38, so that the sliding distance of the slip ring 38 is limited. By adjusting the position of the limit ring 311 on the outer side of the cross bar 31, the reset position of the movable plate 4 can be indirectly adjusted. After the steel section is taken out, the movable plate 4 loses its abutment, and at this time, the spring 1 33 recovers its deformation and pushes the slip ring 38 to the side of the limit ring 311.

[0032] Furthermore, a guide groove 13 is provided on the upper surface of the base plate 1, and guide blocks 41 are fixedly connected to both sides of the lower surface of the movable plate 4, and the guide blocks 41 are slidably connected to the inside of the guide groove 13 on the corresponding side; when the movable plate 4 moves, the guide block 41 on the lower surface of the movable plate 4 slides inside the guide groove 13, and the guide groove 13 provides a sliding path for the guide block 41, so that the movable plate 4 can slide along the path of the guide groove 13 when moving.

[0033] Furthermore, guide blocks 511 are fixedly connected to both sides of the lower surface of the top plate 51, and the guide blocks 511 are slidably connected to the inside of the guide groove 13 on the corresponding side; when the top plate 51 moves, it drives the guide blocks 511 to slide inside the guide groove 13, so that the movable plate 4 can exert better clamping force when clamping and fixing the steel section.

[0034] Furthermore, a slide groove 63 is provided on the upper surface of the auxiliary plate 6, and sliders 81 are fixedly connected on both sides of the lower surface of the movable plate 8, and the sliders 81 are slidably connected to the inside of the slide groove 63 on the corresponding side; when the movable plate 8 moves, it drives the slider 81 on the lower surface to slide inside the slide groove 63, which can play a guiding and limiting role for the movable plate 8.

[0035] Furthermore, a sliding hole 82 is formed through the surface of the movable plate 8, and the elastic clamping plate part 9 includes a guide rod 91 and a movable clamping plate 92. The guide rod 91 is slidably connected to the inside of the sliding hole 82, and the movable clamping plate 92 is fixedly connected to the rear side of the guide rod 91. A spring 93 is sleeved on the outer side of the guide rod 91, and one end of the spring 93 abuts against the front side of the movable clamping plate 92, and the other end of the spring 93 abuts against the rear side of the movable plate 8. A fixed block 94 is fixedly connected to the front side of the guide rod 91; when the cut end of the steel section is clamped, as the telescopic end of the hydraulic rod 27 is extended, relative movement occurs between the movable clamping plate 92 and the movable plate 8, and the movable plate 8 drives the guide rod 91 to slide inside the sliding hole 82, and the mutual cooperation between the guide rod 91 and the sliding hole 82 limits the moving path of the movable plate 8. When clamping, the spring 3 93 is compressed, and at the same time, the spring 3 93 applies elastic force in the opposite direction, which can provide a firm clamping force for the steel section, and prevent the cut end of the steel section from bouncing up or flying out after the cutting is completed. At the same time, when cutting the steel section, since the cut end of the steel section is in an elastic fixed state, a certain range of movement is provided for the steel section, which can reduce the stress concentration in the cutting area and reduce the risk of deformation or cracks.

[0036] Working principle: When using a cold saw to cut the steel, place the steel on the upper surface of the base plate 1 and between the movable plate 4 and the top plate 51. After placement, the telescopic end of the hydraulic rod 5 is extended through the control box to drive the top plate 51 to move toward the steel. While moving, the top plate 51 transmits thrust to the steel, pushing the steel to move toward the movable plate 4. When the steel is clamped between the top plate 51 and the movable plate 4, the telescopic end of the hydraulic rod 5 continues to extend, thereby driving the top plate 51, the steel and the movable plate 4 to move toward the side plate 11. At this time, the slide bar 34 moves inside the slide tube 3, and drives the slip ring 38 to slide on the outside of the cross bar 31 through the diagonal braces 37 on both sides of the slide bar 34. The slip ring 38 drives the metal plate 381 to approach the proximity switch 321 until the rear side of the movable plate 4 abuts against the contact block 21. At the same time, the metal plate 381 also enters the sensing range of the proximity switch 321. At this time, the proximity switch 321 transmits a signal to the control box, which controls the hydraulic rod 15 to stop operating. At this time, the steel section is firmly clamped between the movable plate 4 and the top plate 51. The hydraulic rod 27 will operate and stop synchronously with the hydraulic rod 15. When the hydraulic rod 27 is in operation, its telescopic end drives the movable plate 8 and the elastic clamping plate 19 to move toward the side plate 3 61, and the cut end of the steel section can be elastically clamped between the movable clamping plate 92 and the elastic clamping plate 2 10.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
