Description

Technical Field

[0001] The invention belongs to the field of sawing equipment, and in particular relates to a metal bar cutting and blanking equipment. Background Art

[0002] In modern industrial manufacturing, metal bars serve as the basic raw materials for many fields such as forging and machining. The efficiency and flexibility of their cutting process are directly related to the quality, cost and production cycle of subsequent processing.

[0003] Traditionally, and in some existing technologies, there are two main modes for cutting metal bars: single cutting and row cutting. Single cutting involves cutting only one metal bar at a time. After each section is cut, the bar must be fed forward and wait for the next cut. This method is inefficient and labor-intensive in large-scale production, making it difficult to meet the time-efficiency requirements of modern industrial production.

[0004] To improve cutting efficiency, a number of row-cutting and blanking equipment have emerged on the market. These devices can cut multiple metal bars simultaneously, significantly improving production efficiency. However, current row-cutting and blanking equipment has a significant limitation: they can generally only cut billets of the same length. In actual production, billets of varying lengths are often required due to different forging processes or product requirements. Existing row-cutting and blanking equipment is unable to meet such diverse demands and is unable to simultaneously cut billets of different blanking lengths, resulting in limited production flexibility. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a metal bar cutting and blanking equipment, which can not only realize the simultaneous cutting of multiple metal bars, but also flexibly adjust the cutting length according to different needs, and realize the simultaneous cutting of billets of different blanking lengths.

[0016] Furthermore, the mounting seat is movably connected to the connecting rod, and an adjusting bolt is threadedly connected to the upper portion of the mounting seat, and the lower end of the adjusting bolt is abutted against the connecting rod.

[0020] Furthermore, the filler is a spring, the upper end of the spring abuts against the cover plate, and the lower end of the spring abuts against the pressure rod, so that the pressure rod forms a floating pressure rod in the vertical direction.

[0021] Furthermore, the filler is steel balls, and a flow gap is provided between the steel balls and the cover plate.

[0022] The beneficial effects of the present invention are:

[0023] 1) The present invention uses a positioning mechanism to position the blanking length of the metal bar, uses a clamping mechanism and a pressing mechanism to fix multiple metal bars arranged side by side, and uses a movable sawing mechanism to cut the multiple metal bars one by one. It can not only realize the simultaneous cutting of multiple metal bars, but also can flexibly adjust the cutting length according to different needs, thereby improving the efficiency of blanking.

[0024] 2) A chip box is set inside the bed, and a protective cover is used to guide metal debris into the chip box, which is convenient for collecting the debris cut by the metal bar saw and effectively prevents the chips from flying.

[0027] 5) A telescopic arm is set on one side of the fixed arm to facilitate the flexible adjustment of the position of the positioning mechanism according to the cutting length of the metal bar, so as to meet the positioning requirements of metal bars of different lengths.

[0028] 6) A material guide plate and a material guide mechanism are set on one side of the bed, which can automatically adjust the blanking direction according to the falling position of the blank without an external power source.

[0029] 7) The filler is set as a spring so that the pressure rod forms a floating pressure rod in the vertical direction, which can be adaptively adjusted according to the diameter and surface shape of the metal bar to ensure that all metal bars can be evenly and stably compressed.

[0030] 8) The filler is steel balls, with a flow gap between the balls and the cover plate. When the compression rod compresses metal bars of varying diameters, the length of the rod extending from the loading box changes accordingly. The steel balls then flow within the loading box to accommodate the changes in the rod's position. As the rod is pressed downward, the steel balls gradually fill the flow gap between the rod and the cover plate until the entire gap is completely filled, achieving uniform compression of the metal bars and enhancing the versatility and flexibility of the equipment.

[0052] Example 1

[0053] like Figure 1 、 Figure 2 As shown, a metal bar cutting and blanking device includes a bed 1, a sawing mechanism 2, a clamping mechanism 3, a pressing mechanism 4 and a positioning mechanism 5. A loading mechanism 7 is provided on one side of the bed 1 for loading the bar when sawing. A receiving groove is provided on the work surface above the bed 1 for accommodating a saw blade 26. A crossbeam 12 is provided inside the bed 1, and a first guide rail 13 is provided on the crossbeam 12.

[0054] like Figure 5 、 Figure 6As shown, the sawing mechanism 2 is arranged inside the bed 1, and the sawing mechanism 2 includes a slide 17, a first slider 18 slidably connected to the first guide rail 13 is provided at the lower part of the slide 17, and a first telescopic mechanism 16 is provided on one side of the bed 1, and one end of the first telescopic mechanism 16 is connected to the slide 17, for pushing the sawing mechanism 2 to reciprocate on the first guide rail 13 to achieve sequential cutting of multiple metal bars; a motor 21 is provided on the slide 17, and a driving pulley 22 is installed on the output shaft of the motor 21. The slide 17 is also provided with a support frame 28, and a shaft sleeve 23 is provided on the support frame 28. A rotating shaft 24 is rotatably connected inside the shaft sleeve 23, and a driven pulley 25 is provided at one end of the rotating shaft 24. The driving pulley 22 and the driven pulley 25 are connected by a belt, and the other end of the rotating shaft 24 is connected to a saw blade 26;

[0055] like Figure 4 As shown, the clamping mechanism 3 is used to horizontally clamp multiple metal bars. The clamping mechanism 3 includes a second telescopic mechanism 33 fixedly mounted on the upper part of the bed 1. One end of the second telescopic mechanism 33 is connected to a movable clamping plate 32. A fixed clamping plate 31 is fixedly mounted on the bed 1. Multiple metal bars are clamped between the movable clamping plate 32 and the fixed clamping plate 31.

[0056] like Figure 7 As shown, the pressing mechanism 4 is used to vertically press multiple metal bars, and works together with the clamping mechanism 3 to ensure the stability of the clamping when the metal bars are arranged and cut; the pressing mechanism 4 includes a portal frame 41, and second guide rails 43 are provided on the inner walls of both sides of the portal frame 41. A third telescopic mechanism 42 is provided on the upper part of the portal frame 41. A loading box 44 is provided inside the portal frame 41, and second sliders 47 are provided on both sides of the loading box 44 to be slidably connected to the second guide rails 43. A cover plate 45 is provided on the upper part of the loading box 44, and one end of the third telescopic mechanism 42 is connected to the cover plate 45. A plurality of pressure rods 46 are provided on the lower part of the loading box 44.

[0057] like Figure 8 As shown, the positioning mechanism 5 is used to limit the cutting length of the metal bar. The positioning mechanism 5 includes two groups of fixed arms 51 installed on one side of the bed 1. One end of the two fixed arms 51 is connected by a connecting rod 54. The connecting rod 54 is provided with a plurality of mounting seats 55. A thrust plate 58 is movably installed on the mounting seat 55. A tightening mechanism 57 is provided on one side of the mounting seat 55 for fixing the thrust plate 58.

[0058] In other embodiments, a cooling mechanism (not shown in the figure) is further included to cool the saw blade 26 by spraying a cooling liquid.

[0059] Through the above structure, when multiple metal bars are cut at the same time, the position of the thrust plate 58 of the positioning mechanism 5 is first adjusted according to the cutting length of the multiple metal bars, and the thrust plate 58 is fixed by using the tightening mechanism 57. Then, the multiple metal bars are transported to the side of the bed 1 by using the loading mechanism 7 until the end of the metal bar is against the end of the thrust plate 58, completing the positioning of the cutting length of the metal bars. Then, the clamping mechanism 3 and the pressing mechanism 4 are used to fix the multiple metal bars on the bed 1, and the motor 21 is started. The motor 21 drives the saw blade 26 to rotate through the belt drive, and the first telescopic mechanism 16 is extended to drive the sawing mechanism 2 to move forward, cutting and cutting the multiple metal bars one by one, realizing the simultaneous cutting of blanks of different cutting lengths, and improving the flexibility of production.

[0060] like Figure 3-Figure 5 As shown, in this embodiment, the first telescopic mechanism 16, the second telescopic mechanism 33 and the third telescopic mechanism 42 use oil cylinders. In other embodiments, the first telescopic mechanism 16, the second telescopic mechanism 33 and the third telescopic mechanism 42 can also use air cylinders or electric push rods.

[0061] like Figure 5 As shown, a guard 27 is installed on one side of the support frame 28. The upper and lower ends of the guard 27 are open. The saw blade 26 is arranged inside the guard 27. Two groups of guide plates 14 are provided inside the bed 1. A removable chip box 15 is provided between the two groups of guide plates 14 for collecting debris cut from the metal bar. The opening at the lower end of the guard 27 is aligned with the chip box 15.

[0062] like Figure 9 As shown, a scale line 59 is provided on the thrust plate 58 for visually judging the blanking length of the metal bar.

[0063] like Figure 8 、 Figure 9 As shown, the mounting seat 55 is movably connected to the connecting rod 54, and an adjusting bolt 56 is threadedly connected to the upper part of the mounting seat 55, and the lower end of the adjusting bolt 56 is against the connecting rod 54; in view of the situation where the distances between adjacent bars of different diameters are unequal after arrangement, the above scheme is used to adjust the position of the thrust plate 58, thereby improving the adaptability of the equipment to metal bars of different specifications and broadening the application range of the equipment.

[0064] like Figure 9 As shown, the tightening mechanism 57 adopts a quick clamp, and the lower end of the quick clamp abuts against the upper surface of the thrust plate 58, which facilitates the rapid adjustment and fixation of the thrust plate 58 and improves the efficiency of metal bar blanking.

[0065] like Figure 8As shown, the fixed arm 51 is a hollow structure, and a fastening bolt 53 is threadedly connected to one side of the fixed arm 51. A telescopic arm 52 is slidably connected inside the fixed arm 51, and both ends of the connecting rod 54 are respectively connected to the telescopic arms 52 on both sides, so that the positioning mechanism 5 can be flexibly adjusted according to the cutting length of the metal bar; when processing shorter metal bars, the telescopic arm 52 can be retracted into the fixed arm 51 to reduce the overall length of the positioning mechanism 5; when processing longer metal bars, the telescopic arm 52 is pulled out from the fixed arm 51 and fixed by the fastening bolt 53, thereby expanding the application range of the positioning mechanism 5 and meeting the positioning requirements of metal bars of different lengths.

[0066] like Figure 10 As shown, a tilted material guide plate 11 is provided on one side of the bed 1, and a material guide mechanism 6 is provided at the lower portion of the material guide plate 11. The material guide mechanism 6 includes a side bracket 61 fixedly mounted on the side wall of the bed 1, a material guide tray 63 is pivotally connected to the side bracket 61, and both sides of the side bracket 61 are movably connected to the limit rod 62 via a pin 64;

[0067] Since the material guide tray 63 is pivotally connected to the side bracket 61 and can be tilted to the left and right sides of the bed 1, when the blank falls on the left side of the tray, the tray tilts to the left until it contacts the left limit rod 62; the blank on the right side causes the tray to tilt to the right, thereby automatically adjusting the blanking direction according to the blank falling position, and no additional power source is required, and the blanking direction can be adjusted by relying solely on the blank's own gravity.

[0068] In addition, since the limiting rod 62 is movably connected to the side bracket 61 through the pin 64, it automatically rotates when the pallet is tilted, so that the upper surface of the limiting rod 62 remains parallel to the lower surface of the pallet, thereby increasing the contact area between the material guide tray 63 and the limiting rod 62, and converting the original line contact into surface contact, effectively dispersing stress and reducing the wear of the material guide tray 63 and the limiting rod 62.

[0069] In some embodiments, a conveying mechanism (not shown in the figure) is provided on each side of the material guiding mechanism 6 for conveying blanks of different specifications to corresponding processing stations.

[0070] like Figure 11 As shown, the filler 48 is a spring, the upper end of the spring abuts against the cover plate 45, and the lower end of the spring abuts against the pressure rod 46, so that the pressure rod 46 forms a floating pressure rod 46 in the vertical direction;

[0071] When the third telescopic mechanism 42 drives the loading box 44 downward, the compression rods 46 first contact the metal bars. Due to the elastic properties of the springs, the compression rods 46 can adaptively adjust according to the diameter and surface shape of the metal bars. For larger diameter metal bars, the compression rods 46 experience a greater reaction force, compressing the springs and moving them upward a certain distance. For smaller diameter metal bars, the spring compression is relatively small, and the compression rods 46 are lowered relatively low. Each compression rod 46 can be independently adjusted based on the actual condition of the metal bars below it, ensuring that all metal bars are evenly and stably compressed. Furthermore, the floating compression rod 46 structure is also suitable for compressing irregularly shaped bars.

[0072] Example 2

[0073] Different from Example 1, Figure 12 As shown, filler 48 is composed of steel balls, with a flow gap between the steel balls and cover plate 45. When compression rod 46 compresses metal bars of varying diameters, the length of rod 46 extending from loading box 44 changes accordingly. The steel balls then flow within loading box 44 to accommodate the changing position of compression rod 46. As compression rod 46 is pressed downward, the steel balls gradually fill the flow gap between compression rod 46 and cover plate 45 until the entire gap is completely filled. This ensures uniform compression of the metal bars, enhancing the versatility and flexibility of the device.

[0074] The above content is merely an example and explanation of the structure of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the invention, they should all fall within the scope of protection of the present invention.
