Description

Technical Field

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

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

[0003] In traditional and some existing technologies, there are mainly two modes for cutting and blanking metal bars: single cutting and row cutting and blanking. The single cutting method means that only one metal bar is cut each time. After cutting a section of blank each time, the bar needs to be fed forward and wait for the next cut. This method is inefficient in mass production and has a large labor intensity, making it difficult to meet the requirements of modern industrial production for time efficiency.

[0004] In order to improve the cutting efficiency, some row cutting and blanking equipment has emerged in the market. These equipment can cut multiple metal bars simultaneously, significantly improving the production efficiency. However, the current row cutting and blanking equipment has a significant limitation: they can usually only cut blanks of the same length. In actual production, due to different forging processes or product requirements, blanks of different lengths are often needed. The existing row cutting and blanking equipment is unable to cope when faced with such diverse requirements and cannot cut blanks of different blanking lengths simultaneously, resulting in limited production flexibility. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a metal bar cutting and blanking equipment that can not only cut multiple metal bars simultaneously but also flexibly adjust the cutting length according to different requirements to achieve the simultaneous cutting of blanks of different blanking lengths, which is of great significance for improving the production efficiency, reducing the production cost, and enhancing the production flexibility in the forging industry.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: A metal bar cutting and blanking equipment, comprising: A bed body, on the side of which a feeding mechanism is provided, and a receiving groove is provided on the working surface of the upper part of the bed body.

[0007] Further, the first telescopic mechanism, the second telescopic mechanism and the third telescopic mechanism are cylinders, oil cylinders or electric push rods.

[0008] Further, a protective cover is installed on one side of the support frame. The upper end and the lower end of the protective cover are both open. The saw blade is arranged inside the protective cover. Two groups of guide plates are provided inside the bed body, and a detachable chip collecting box is provided between the two groups of guide plates. The opening at the lower end of the protective cover is aligned with the chip collecting box.

[0009] Further, scale lines are provided on the thrust plate.

[0010] Further, the mounting seat is movably connected to the connecting rod, and an adjusting bolt is threadedly connected to the upper part of the mounting seat. The lower end of the adjusting bolt abuts against the connecting rod.

[0011] Further, the tightening mechanism uses a quick clamp, and the lower end of the quick clamp abuts against the upper surface of the thrust plate.

[0012] Further, the fixed arm is of a hollow structure, and a fastening bolt is threadedly connected to one side of the fixed arm. A telescopic arm is slidably connected inside the fixed arm, and both ends of the connecting rod are respectively connected to the telescopic arms on both sides.

[0013] Furthermore, an inclined material guide plate is provided on one side of the bed, and a material guide mechanism is provided at the lower part of the material guide plate. The material guide mechanism includes a side bracket fixedly mounted on the side wall of the bed, a material guide tray is pivotally connected to the side bracket, and both sides of the side bracket are movably connected to limit rods through pins.

[0014] 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.

[0015] Furthermore, the filler is a steel ball, and a flow gap is provided between the steel ball and the cover plate.

[0016] The beneficial effects of the present invention are: 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 blank blanking.

[0017] 2) A chip box is set inside the bed, and a protective cover is used to guide metal chips into the chip box, which is convenient for collecting the chips cut by the metal bar saw and effectively prevents the chips from flying.

[0018] 3) By movably connecting the mounting seat with the connecting rod and arranging an adjusting bolt on the mounting seat, the position of the thrust plate can be adjusted, thereby improving the adaptability of the equipment to metal bars of different specifications and broadening the application range of the equipment.

[0019] 4) The tightening mechanism adopts a quick clamp, which facilitates the rapid adjustment and fixation of the thrust plate and improves the efficiency of metal bar unloading.

[0020] 5) A telescopic arm is provided on one side of the fixed arm, so as to flexibly adjust the position of the positioning mechanism according to the cutting length of the metal bar and meet the positioning requirements of metal bars of different lengths.

[0021] 6) A material guide plate and a material guide mechanism are set on one side of the bed, which can automatically adjust the material drop direction according to the falling position of the blank without an external power source.

[0022] 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.

[0023] 8) The filler is set as steel balls, and there is a flow gap between the steel balls and the cover plate. When the pressure rod compresses metal bar stocks with different diameters, due to the difference in the diameters of the metal bar stocks, the length of the pressure rod extending out of the loading box will change accordingly. At this time, the steel balls will flow in the loading box to adapt to the change in the position of the pressure rod. As the pressure rod presses down, the steel balls will gradually fill the flow gap formed between the pressure rod and the cover plate until the entire gap is filled, thus achieving uniform compression of the metal bar stocks and improving the versatility and flexibility of the equipment.

[0039] Embodiment 1 As Figure 1 、 Figure 2 shown, a metal bar cutting and blanking device includes a bed body 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 body 1 for loading materials during bar sawing; a receiving groove is provided on the workbench surface at the upper part of the bed body 1 for receiving the saw blade 26; a cross beam 12 is provided inside the bed body 1, and a first guide rail 13 is provided on the cross beam 12; As Figure 5 、 Figure 6As shown in the figure, the sawing mechanism 2 is arranged inside the machine tool bed 1. The sawing mechanism 2 includes a sliding seat 17. A first slider 18 that is slidably connected to the first guide rail 13 is provided at the lower part of the sliding seat 17. A first telescopic mechanism 16 is provided on one side of the machine tool bed 1. One end of the first telescopic mechanism 16 is connected to the sliding seat 17 and is used to push the sawing mechanism 2 to reciprocate on the first guide rail 13 so as to sequentially cut a plurality of metal bar stocks. A motor 21 is provided on the sliding seat 17. A driving pulley 22 is installed on the output shaft of the motor 21. A support frame 28 is further provided on the sliding seat 17. A bushing 23 is provided on the support frame 28. A rotating shaft 24 is rotatably connected inside the bushing 23. 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. A saw blade 26 is connected to the other end of the rotating shaft 24. As Figure 4 shown in the figure, the clamping mechanism 3 is used to horizontally clamp a plurality of metal bar stocks. The clamping mechanism 3 includes a second telescopic mechanism 33 fixedly installed on the upper part of the machine tool 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 installed on the machine tool bed 1. A plurality of metal bar stocks are clamped between the movable clamping plate 32 and the fixed clamping plate 31. As Figure 7 shown in the figure, the pressing mechanism 4 is used to vertically press a plurality of metal bar stocks and, in conjunction with the clamping mechanism 3, ensures the stability of the clamping during the row cutting of the metal bar stocks. The pressing mechanism 4 includes a portal frame 41. Second guide rails 43 are provided on the inner walls on 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. Second sliders 47 that are slidably connected to the second guide rails 43 are provided on both sides of the loading box 44. A cover plate 45 is provided on the upper part of the loading box 44. One end of the third telescopic mechanism 42 is connected to the cover plate 45. A plurality of pressing rods 46 are provided at the lower part of the loading box 44. As Figure 8 shown in the figure, the positioning mechanism 5 is used to limit the blanking length of the metal bar stocks. The positioning mechanism 5 includes two groups of fixed arms 51 installed on one side of the machine tool bed 1. One ends of the two fixed arms 51 are connected by a connecting rod 54. A plurality of mounting seats 55 are provided on the connecting rod 54. A thrust plate 58 is movably installed on the mounting seats 55. A jacking mechanism 57 is provided on one side of the mounting seats 55 for fixing the thrust plate 58.

[0040] In other embodiments, a cooling mechanism (not shown in the figure) is further included to cool down the saw blade 26 by spraying coolant.

[0041] With the above structure, when multiple metal bar stocks are cut simultaneously, first adjust the position of the thrust plate 58 of the positioning mechanism 5 according to the cutting lengths of the multiple metal bar stocks, and fix the thrust plate 58 using the clamping mechanism 57. Then, convey the multiple metal bar stocks to one side of the bed body 1 using the feeding mechanism 7 until the ends of the metal bar stocks abut against the end of the thrust plate 58 to complete the positioning of the cutting lengths of the metal bar stocks. Next, fix the multiple metal bar stocks on the bed body 1 using the clamping mechanism 3 and the pressing mechanism 4. Start the motor 21, and the motor 21 drives the saw blade 26 to rotate through belt transmission. The first telescopic mechanism 16 extends to drive the sawing mechanism 2 to move forward, and cut the multiple metal bar stocks one by one, realizing the simultaneous cutting of blanks with different cutting lengths and improving the production flexibility.

[0042] As Figures 3-5 shown, in this embodiment, the first telescopic mechanism 16, the second telescopic mechanism 33, and the third telescopic mechanism 42 adopt oil cylinders. In other embodiments, the first telescopic mechanism 16, the second telescopic mechanism 33, and the third telescopic mechanism 42 can also adopt air cylinders or electric push rods.

[0043] As Figure 5 shown, a protective cover 27 is installed on one side of the support frame 28. Both the upper end and the lower end of the protective cover 27 are open. The saw blade 26 is arranged inside the protective cover 27. Two groups of guide plates 14 are provided inside the bed body 1, and a detachable chip collection box 15 is provided between the two groups of guide plates 14 for collecting the chips cut from the metal bar stocks. The opening at the lower end of the protective cover 27 is aligned with the chip collection box 15.

[0044] As Figure 9 shown, scale lines 59 are provided on the thrust plate 58 for visually judging the cutting lengths of the metal bar stocks.

[0045] As Figure 8 , Figure 9 shown, the mounting seat 55 is movably connected to the connecting rod 54. 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 abuts against the connecting rod 54. For the situation where the distances between adjacent bar stocks are unequal after arranging metal bar stocks with different diameters, through the above solution, the adjustment of the position of the thrust plate 58 is realized, improving the adaptability of the equipment to metal bar stocks of different specifications and broadening the application range of the equipment.

[0046] As Figure 9 shown, the clamping mechanism 57 adopts a quick clamp. The lower end of the quick clamp abuts against the upper surface of the thrust plate 58, facilitating the quick adjustment and fixation of the thrust plate 58 and improving the cutting efficiency of the metal bar stocks.

[0047] As Figure 8As shown, the fixed arm 51 has a hollow structure. 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. Both ends of the connecting rod 54 are connected to the telescopic arms 52 on both sides, enabling the positioning mechanism 5 to be flexibly adjusted according to the cutting length of the metal bar stock. When processing shorter metal bar stocks, 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 bar stocks, the telescopic arm 52 is pulled out from the fixed arm 51 and fixed by the fastening bolt 53, thereby expanding the applicable range of the positioning mechanism 5 to meet the positioning requirements of metal bar stocks of different lengths.

[0048] As Figure 10 shown, a guide plate 11 arranged obliquely is provided on one side of the bed body 1. A feeding mechanism 6 is provided at the lower part of the guide plate 11. The feeding mechanism 6 includes a side bracket 61 fixedly installed on the side wall of the bed body 1. A feeding tray 63 is pivotally connected to the side bracket 61. Limiting rods 62 are movably connected to both sides of the side bracket 61 through pin shafts 64. Since the feeding tray 63 is pivotally connected to the side bracket 61 and can tilt to the left and right sides of the bed body 1, when the blank falls on the left side of the tray, the tray tilts to the left until it contacts the left limiting rod 62. The blank on the right side causes the tray to tilt to the right, realizing the automatic adjustment of the blanking direction according to the falling position of the blank, and no additional power source is required. The adjustment of the blanking direction can be completed only relying on the self-gravity of the blank.

[0049] In addition, since the limiting rod 62 is movably connected to the side bracket 61 through the pin shaft 64 and automatically rotates when the tray tilts, the upper surface of the limiting rod 62 remains parallel to the lower surface of the tray, increasing the contact area between the feeding tray 63 and the limiting rod 62, changing the original line contact to surface contact, effectively dispersing stress, and reducing the wear of the feeding tray 63 and the limiting rod 62.

[0050] In some embodiments, a conveying mechanism (not shown in the figure) is provided on each side of the feeding mechanism 6 for conveying blanks of different specifications to corresponding processing stations.

[0051] As Figure 11 shown, the packing 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, making the pressure rod 46 form a floating pressure rod 46 in the vertical direction. When the third telescopic mechanism 42 drives the loading box 44 to move downward, the pressure rod 46 first contacts the metal bar stock. Due to the elastic characteristics of the spring, the pressure rod 46 can be adaptively adjusted according to the diameter and surface shape of the metal bar stock. For metal bar stocks with a larger diameter, the pressure rod 46 receives a greater reaction force, the spring is compressed, and the pressure rod 46 moves upward by a certain distance; for metal bar stocks with a smaller diameter, the compression amount of the spring is relatively small, and the downward pressure position of the pressure rod 46 is relatively low. Each pressure rod 46 can be independently adjusted according to the actual situation of the metal bar stock below it to ensure that all metal bar stocks can be evenly and stably clamped; in addition, the floating pressure rod 46 structure is also applicable to the clamping of special-shaped bar stocks.

[0052] Embodiment 2 Different from Embodiment 1, as Figure 12 shown, the filler 48 is steel balls, and there is a flow gap between the steel balls and the cover plate 45. When the pressure rod 46 clamps metal bar stocks with different diameters, due to the difference in the diameter of the metal bar stocks, the length of the pressure rod 46 extending out of the loading box 44 will change accordingly. At this time, the steel balls will flow inside the loading box 44 to adapt to the change in the position of the pressure rod 46. As the pressure rod 46 presses down, the steel balls will gradually fill the flow gap formed between the pressure rod 46 and the cover plate 45 until the entire gap is filled, so as to achieve uniform clamping of the metal bar stock and improve the versatility and flexibility of the equipment.

[0053] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of the present technology can make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the scope defined by the structure of the invention, they should fall within the protection scope of the present invention.
