DETAILED DESCRIPTION

[0021] The multi-support adjustable bar stock cutting device is composed of a frame 1, a cutting machine and an adjusting and positioning support mechanism. The frame 1 is provided with the cutting machine to cut the bar stock by the cutting machine. The frame 1 on one side of the cutting machine is provided with the adjusting and positioning support mechanism to support and fix the bar stock by the adjusting and positioning support mechanism, and at the same time, the adjusting and positioning support mechanism itself is adjusted to adapt to the diameter of the bar stock to ensure the accurate fixing of the bar stock by the adjusting and positioning support mechanism, so that the bar stock is not easy to shake during the cutting process, and the cutting precision is ensured.

[0022] The adjusting and positioning support mechanism is composed of a limiting frame, a positioning baffle 2, rollers 3 and an adjuster. The limiting frame is provided with the positioning baffle 2 on one side to position the end of the bar stock by the positioning baffle 2, so as to determine the distance between the end of the bar stock and the cutting machine, thereby controlling the cutting length of the bar stock. The limiting frame serves to limit and fix the bar stock by the limiting frame to prevent the bar stock from shaking during the cutting process, thereby ensuring the cutting precision. The limiting frame is provided with multiple groups of rollers 3 on both sides. The rollers 3 are connected with the frame 1 by the adjuster which can adjust the distance between the rollers 3. The rollers 3 serve to support the bar stock by the rollers 3, and at the same time, the bar stock is rolled by the rollers 3 to adjust the cutting position. Since the distance between the rollers 3 can be adjusted by the adjuster, the distance between the rollers 3 can be adapted to the diameter of the bar stock, so that the rollers 3 can fully support the bar stock and control the support position of the rollers 3, and then the bar stock can be limited by the rollers 3 to prevent the rollers 3 from being separated from the bar stock. The positioning baffle 2 is connected with the frame 1 by the end adjusting slide rail 4. The end adjusting slide rail 4 serves to adjust the position of the positioning baffle 2 by the end adjusting slide rail 4, and then adjust the distance between the positioning baffle 2 and the cutting machine, thereby adjusting the cutting length of the bar stock.

[0023] The limiting frame consists of multiple guide rods 5 arranged in parallel, an adjusting support plate 6, an upper clamping plate 7, and a lower clamping plate 8. The guide rods 5 are sequentially topped with the adjusting support plate 6, the upper clamping plate 7, and the lower clamping plate 8. The adjusting support plate 6 is fixedly connected to the top of the guide rod 5. The upper clamping plate 7 and the lower clamping plate 8 are connected to the guide rod 5 via sleeves. The upper clamping plate 7 is connected to the adjusting support plate 6 via a lifting screw 9 and a lifting screw nut. The guide rod 5 is fixedly connected to the frame 1. The function of the lifting screw 9 is to drive the upper clamping plate 7 to rise and fall through the cooperation of the lifting screw 9 and the lifting screw nut. This, in turn, allows the upper clamping plate 7 to work in conjunction with the lower clamping plate 8 to clamp the bar stock, thus fixing the bar stock and preventing it from shaking during cutting.

[0024] Symmetrical end support plates 10 are arranged on the positioning baffle 2 on one side of the roller 3 to support and limit the end of the bar stock, preventing the end of the bar stock from shaking, thereby further improving the stability of the bar stock during the cutting process and further improving the cutting accuracy. Both ends of the end support plates 10 are connected to the positioning baffle 2 via lifting slide rails. The function of the lifting slide rails is to adjust the position of the end support plates 10, thereby adapting the position of the end support plates 10 and the spacing between the end support plates 10 to the bar stock, ensuring that the end support plates 10 can accurately limit the bar stock.

[0025] The end support plate 10, the upper clamping plate 7, and the lower clamping plate 8 are V-shaped to increase the contact area between the end support plate 10, the upper clamping plate 7, and the lower clamping plate 8 and the bar stock, while also enhancing the limiting effect of the end support plate 10, the upper clamping plate 7, and the lower clamping plate 8 on the bar stock.

[0026] The adjuster is composed of an assembling plate 11, slide bars 12, adjusting seats 13, spacing adjustment lead screws 14 and rotating handles 15. The slide bars 12 are arranged side by side on the assembling plate 11, and the adjusting seats 13 are arranged at the two ends of the slide bars 12 respectively. The spacing adjustment lead screws 14 are arranged between the slide bars 12, and the screw thread directions of the two ends of the spacing adjustment lead screws 14 are opposite. The spacing adjustment lead screws 14 are threadedly connected with the adjusting seats 13. The end of the spacing adjustment lead screw 14 is provided with the rotating handle 15. The assembling plate 11 is movably connected with the rack 1 through a positioning and adjusting slide rail 16. The adjusting seat 13 is movably connected with the roller 3 through a pin shaft. The spacing adjustment lead screw 14 drives the adjusting seat 13 to slide on the slide bar 12 through the screw thread of the spacing adjustment lead screw 14 during the rotation of the spacing adjustment lead screw 14 driven by the rotating handle 15, and then the position of the adjusting seat 13 is moved, so that the position of the roller 3 is adjusted. Since the screw thread directions of the two ends of the spacing adjustment lead screw 14 are opposite, the spacing adjustment lead screw 14 can drive the adjusting seats 13 at the two ends of the spacing adjustment lead screw 14 to approach each other during the forward rotation of the spacing adjustment lead screw 14, and then the spacing between the rollers 3 is reduced. The spacing adjustment lead screw 14 can drive the adjusting seats 13 at the two ends of the spacing adjustment lead screw 14 to move away from each other during the reverse rotation of the spacing adjustment lead screw 14, and then the spacing between the rollers 3 is increased. The positioning and adjusting slide rail 16 adjusts the position of the assembling plate 11, and then the roller 3 is driven to move along the positioning and adjusting slide rail 16 through the slide bar 12 and the adjusting seat 13 during the adjustment of the assembling plate 11, and then the distribution of the roller 3 is adjusted, so that the roller 3 can uniformly support the bar material.

[0027] The cutting machine is composed of a support seat 17, a sliding frame 18, a gearbox 19, a cutting motor 20, a cutting saw blade 21 and a lifting cylinder 22. The sliding frame 18 is obliquely installed on the support seat 17 through a cutting slide rail 23. The gearbox 19 is arranged on the sliding frame 18. The cutting motor 20 is connected with the input shaft of the gearbox 19. The cutting saw blade 21 is connected with the output shaft of the gearbox 19. The lifting cylinder 22 is arranged at the top of the cutting slide rail 23. The piston rod of the lifting cylinder 22 is connected with the sliding frame 18. The support seat 17 is connected with the rack 1 through the cutting adjusting slide rail 24 arranged side by side. The cutting motor 20 drives the gearbox 19 to rotate, and then drives the cutting saw blade 21 to rotate, so that the bar material is cut by the rotating cutting saw blade 21. The lifting cylinder 22 drives the sliding frame 18 to move along the cutting slide rail 23, and then drives the gearbox 19 to slide, so that the cutting saw blade 21 slides, and the cutting saw blade 21 can gradually deepen the cutting depth, or is separated from the bar material after the cutting is completed.

[0028] Before cutting the new diameter bar, the rotating handle 15 is rotated according to the diameter of the bar, so as to rotate the spacing adjusting screw 14 and adjust the spacing between the rollers 3. After adjusting the spacing between the rollers 3, the assembly plate 11 of each adjuster is pushed, and then the rollers 3 are pushed to move along the positioning adjusting slide rail 16, the supporting position of the rollers 3 in the axial direction of the bar is adjusted, and the rollers 3 can uniformly support the bar. After the assembly plate 11 is adjusted, the position of the lower clamping plate 8 is adjusted, so that the lower clamping plate 8 is aligned with the rollers, thereby ensuring that the lower clamping plate 8 can clamp and support the bar. After the lower clamping plate 8 is adjusted, the position of the end support plate 10 is adjusted, so that the spacing between the end support plates 10 is adapted to the diameter of the bar and can limit the ends of the bar. After the end support plate 10 is adjusted, the positioning baffle 2 is pushed, and the support seat 17 is pushed at the same time, the spacing between the positioning baffle 2 and the cutting machine is adjusted, thereby adjusting the cutting length of the bar. After each of the above adjustments is completed, the position is locked by the jack, specifically, the position of the adjusting seat 13 and the slide rod 12, the position of the assembly plate 11 and the positioning adjusting slide rail 16, the position of the lower clamping plate 8 and the guide rod 5, the position of the end support plate 10 and the lifting slide rail, the position of the positioning baffle 2 and the end adjusting slide rail 4, and the position of the support seat 17 and the cutting adjusting slide rail 24 are locked by the jack respectively.

[0029] When the multi-support adjustable bar cutting device cuts the bar, the bar is placed between the upper clamping plate 7 and the lower clamping plate 8, the ends are abutted on the positioning baffle 2 between the end support plates 10, and the bar is placed on the rollers 3. After the bar is hoisted into position, the lifting screw 9 is rotated, the upper clamping plate 7 is lowered by the lifting screw 9, and the bar is clamped and fixed between the upper clamping plate 7 and the lower clamping plate 8. After the bar is clamped and fixed, the cutting motor 20 is started, the cutting motor 20 drives the cutting saw blade 21 to rotate through the gearbox 19, the cutting saw blade 21 starts to rotate, the lifting cylinder 22 is started, the lifting cylinder 22 drives the rotating cutting saw blade 21 to descend in sequence through the slide bracket 18 and the gearbox 19, and the bar is cut, and the cutting depth is gradually deepened until the cutting is completed.

[0030] The multi-support adjustable bar cutting device can accurately limit the bar by the limiting frame, can adjust the spacing between the rollers 3 by the adjuster, and can accurately support the bar, so that the bar can be accurately positioned by cooperating with the limiting frame, the bar is not easy to shake during cutting, and the cutting precision is ensured. Because the limiting and positioning are adjusted, different diameters of bars can be adapted, and the universality is effectively enhanced. The problem that the existing cutting machine can only accurately cut a single diameter bar and the bar is easy to shake during cutting of bars of other diameters, resulting in a decrease in cutting precision, is solved.
