Description

Technical Field

[0001] The invention relates to the technical field of circular saw blade processing, in particular to a circular saw blade tooth tip quenching machine tool. Background Art

[0002] Circular saw blades are used for cutting low-hardness carbon steel and non-ferrous metal rods and tubes, cutting superhard pipes, and milling difficult-to-cut materials (heat-resistant iron, stainless steel, and high-hardness steel). Circular saw blades have varying numbers of teeth. Their base is hardened steel, and the blade head is made of tungsten carbide and titanium carbide. Blades with a 0° tooth pitch are designed specifically for cutting steel.

[0003] Saw blades with a tooth inclination of 7° are designed for cutting softer materials (such as aluminum). Specially designed trochoid teeth are used for cutting various steels, stainless steel and aluminum.

[0004] Currently, circular saw blades need to be quenched at the tooth tips after machining to increase the surface hardness of the tooth tips. However, the existing quenching method is to place the entire circular saw blade in a quenching device, heat it, keep it warm for a period of time, and finally cool it quickly. This quenching method makes it impossible for the existing quenching device to quickly quench the tooth tips of the circular saw blade. Moreover, the cooling of the entire circular saw blade will heat the internal structure of the metal circular saw blade and change its structure. In addition, the metal circular saw blade heats up slowly, and the quenching process takes a lot of time, which affects the quenching efficiency.

[0005] At the same time, the current quenching device immerses the entire circular saw blade into the coolant for cooling during the quenching process of the circular saw blade, resulting in a low quenching frequency, thereby affecting the quenching effect. Therefore, a circular saw blade tooth tip quenching machine is proposed to solve the above problem. Summary of the Invention

A heater 29 is fixedly installed on the upper surface of each rectangular block 28, and a clamping block 27 is fixedly connected to the opposite side of the two rectangular blocks 28.

[0042] In this embodiment, since the started first servo motor 22 can drive the two side columns 26 to move toward or away from one side by driving the screw rod 23, it can drive the support rod 214 and the clamping block 27 on the lifting plate 210 to follow the adjustment, and the started first cylinder 25 can drive the lifting plate 210 to rise and fall together after driving the mounting plate 218 to rise and fall along the vertical and horizontal plane, so as to drive the clamping block 27 to rise and align it with the discharge end of the feeding member 6, clamp the feeding member 6 out, and lower it to between the rotating ring 213 and the rotating member 4, and then cooperate with the driving member 3 to drive the sliding frame 21 to send the lowered circular saw blade onto the rotating member 4, and then cooperate with the rotating member 4 to drive the circular saw blade to rotate axially after the rotating ring 213 pushed by the second cylinder 217 hits the circular saw blade. During the rotation process, the first servo motor 22 is reset to drive the clamping block 27 to separate from the circular saw blade, and the heater 29 is started to heat the circular saw blade during the rotation process.

[0043] It should be noted that the lifting plate 210 and the column 26 are provided with a guide assembly for limiting the stable lifting and lowering of the lifting plate 210; the guide assembly includes a guide block 215 fixedly connected to one side of the lifting plate 210, and a guide rod 216 with one end passing through the guide block 215 is fixedly connected to the column 26. The guide rod 216 passing through the guide block 215 allows the lifting plate 210 to be stably raised and lowered and adjusted on the column 26.

[0044] Among them, a first threaded hole is opened at the lower end of the column 26, and the first threaded hole is adapted to the thread on the outside of the driving screw 23.

[0045] In addition, the clamping block 27 is arc-shaped, and an arc-shaped support groove is provided on the inner side of the clamping block 27. The support groove on the clamping block 27 facilitates the clamping and fixing of the circular saw blade. The inner wall of the support ring 212 is rotatably connected to the rotating ring 213 through a bearing, so that the rotating ring 213 can rotate on the support ring 212 with a stable bearing and will not separate from the support ring 212.

[0046] Secondly, the driving member 3 includes two support blocks 31 fixedly connected to the rear side of the upper surface of the processing table 1, a limiting rod 32 fixedly connected between the two support blocks 31, a group of mounting blocks 36 fixedly connected to the front side of the upper surface of the processing table 1, an adjusting screw 34 rotatably connected between the two mounting blocks 36, a second servo motor 33 fixedly mounted on the left mounting block 36, and the output shaft of the second servo motor 33 is fixedly connected to one end of the adjusting screw 34, and the adjusting screw 34 and the limiting rod 32 are both provided with a connecting block 35 with one end fixedly connected to the sliding frame 21. The limiting rod 32 limits the rear connecting block 35, so that the rotating adjusting screw 34 can drive the sliding frame 21 to move and adjust together after driving the front connecting block 35 to adjust laterally along the orientation parallel to the horizontal plane.

[0047] Then, the rear connecting block 35 is slidably connected to the limit rod 32, the front connecting block 35 is threadedly connected to the adjusting screw 34, and a second threaded hole is provided on the front connecting block 35 that is compatible with the outer thread of the adjusting screw 34, so that the rotating adjusting screw 34 can drive the front connecting block 35 to move horizontally and adjust along the direction parallel to the horizontal plane.

[0048] See also Figure 1 and 3 In this embodiment, the rotating member 4 includes a vertical plate 41 fixedly connected to the processing table 1 and located on the right side of the sliding frame 21. A rotating motor 42 is fixedly installed on the side of the vertical plate 41 away from the sliding frame 21. The output shaft of the rotating motor 42 is fixedly connected to a rotating column 43 with one end passing through the vertical plate 41, and the end of the rotating column 43 away from the vertical plate 41 is convex, and the center of the rotating column 43 and the center of the rotating ring 213 are on the same horizontal line when the circular saw blade is heated.

[0049] In this embodiment, when the middle mounting hole of the circular saw blade is inserted into the convex end of the rotating column 43 and the circular saw blade is abutted by the rotating ring 213, the started rotating motor 42 drives the rotating column 43 to rotate, thereby driving the circular saw blade to rotate, heat the circular saw blade, and cool it.

[0050] See also Figure 1 and 4 In this embodiment, the cooling member 5 includes a cooling groove 51 which passes through the processing table 1 at one end and is slidably connected to the processing table 1. The cooling groove 51 passes through one end of the processing table 1 and is fixedly connected to a connecting plate 54 on one side. The lower surface of the processing table 1 is fixedly connected to a support plate 52. The inner side of the support plate 52 is fixedly connected to a third cylinder 53, and the output shaft of the third cylinder 53 is fixedly connected to the connecting plate 54. The lower end portion of the cooling groove 51 is conical, and a drain port is opened at its conical end. A valve is installed at the drain port of the cooling groove 51.

[0051] In this embodiment, after the coolant required for cooling, such as cooling water or cooling oil, is injected into the cooling groove 51, the started third cylinder 53 drives the connecting plate 54 to drive the cooling groove 51 to rise, so that the tooth tip of the circular saw blade extends into the coolant, and the tooth tip of the circular saw blade is in the process of rotation to complete the rapid cooling of the tooth tip of the circular saw blade.

[0052] It should be noted that a rectangular hole is provided on the processing table 1 for the cooling groove 51 to slide, and the rectangular hole is located between the vertical plate 41 and the sliding frame 21 .

[0053] See also Figure 1 and 5 In this embodiment, the feeding part 6 includes a mounting frame 61 fixedly connected to one side of the processing table 1, the upper end of the mounting frame 61 is fixedly connected to a storage bin 62, the inner side of the storage bin 62 is slidably connected to an extrusion plate 66, the side of the extrusion plate 66 close to the mounting frame 61 is fixedly connected to a pull rod 68 passing through the mounting frame 61, the side of the mounting frame 61 away from the storage bin 62 is fixedly connected to a sleeve 67 covering the outside of the pull rod 68 and passed through by the pull rod 68, the outside of the pull rod 68 is fixedly connected to a fixing ring 69, a spring 610 is fixedly connected between the fixing ring 69 and the inner side of the sleeve 67, and the top of the storage bin 62 is open.

[0054] It should be noted that a discharge hole 64 is provided below the end of the storage bin 62 away from the extrusion plate 66, and a feeding hole 65 is provided above the connection end of the storage bin 62 and the mounting frame 61. Both the feeding hole 65 and the discharge hole 64 are semicircular, which facilitates the feeding and discharging of the circular saw blade into and from the storage bin 62.

[0055] The inner wall of the storage bin 62 is fixedly connected with a rubber pad 63 located at the feeding hole 65. The rubber pad 63 is used to increase the friction force when the circular saw blade is pressed against the discharge hole 64 of the storage bin 62 when the extrusion disk 66 squeezes the circular saw blade.

[0056] In this embodiment, by pulling the pull rod 68 to squeeze the spring 610, and driving the extrusion plate 66 to slide toward the side close to the sleeve 67, and after it is in contact with the side of the storage bin 62 close to the feeding hole 65, the circular saw blade to be processed can be placed through the feeding hole 65, and the circular saw blade can be slid to the discharge hole 64 of the storage bin 62 through the opening of the storage bin 62, but not flush with the discharge hole 64, until the circular saw blades are full. Then, the spring 610 that resets the pull rod 68 can push the pull rod 68 to drive the extrusion plate 66 to squeeze the full circular saw blades, so that the first circular saw blade is flush with the discharge hole 64, thereby completing the loading of the circular saw blades.

[0057] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.

[0058] The working principle of the above embodiment is:

[0059] Pull the pull rod 68 to squeeze the spring 610, and drive the squeezing plate 66 to slide toward the side close to the sleeve 67, and after it is in contact with the side of the storage bin 62 close to the feeding hole 65, the circular saw blade to be processed can be put through the feeding hole 65, and the circular saw blade can be slid through the opening of the storage bin 62 to the discharge hole 64 of the storage bin 62, but not flush with the discharge hole 64, until the circular saw blades are fully loaded. Then, release the spring 610 that resets the pull rod 68, and the pull rod 68 can be pushed to drive the squeezing plate 66 to squeeze the fully loaded circular saw blades, so that the first circular saw blade is flush with the discharge hole 64;

[0060] After the circular saw blade is loaded, the first cylinder 25 can be started to drive the mounting plate 218 to move up and down along the vertical and horizontal planes, thereby driving the lifting plate 210 to move up and down together, thereby driving the clamping block 27 to rise. After the clamping blocks 27 on both sides are aligned with the discharge holes 64 of the storage bin 62, the first servo motor 22 can be started to drive the columns 26 on both sides to move and adjust toward the side close to each other through the driving screw 23, thereby driving the support rods 214 and the clamping blocks 27 on the lifting plate 210 to follow the adjustment, clamping the circular saw blade aligned with the discharge hole 64 to take out the storage bin 62, and lowering it to between the rotating ring 213 and the rotating column 43;

[0061] However, after the second servo motor 33 is activated and drives the slide 21 to move horizontally through the adjustment screw 34, the lowered circular saw blade is sent into the convex end of the rotating column 43. Then, the rotating ring 213 pushed by the second cylinder 217 contacts the circular saw blade, and the rotating column 43 is driven by the rotating motor 42 to drive the circular saw blade to rotate axially. During the rotation process, the first servo motor 22 is reset, driving the clamping block 27 to separate from the circular saw blade, and the heater 29 is started to heat the circular saw blade during the rotation process.

[0062] After the circular saw blade is heated, the third cylinder 53 is activated to drive the connecting plate 54 to raise the cooling groove 51, so that the tooth tip of the circular saw blade extends into the coolant. During the cooling process, the tooth tip of the circular saw blade is allowed to rotate axially to complete the rapid cooling of the tooth tip of the circular saw blade.

[0063] After repeating the above heating and cooling steps, the tooth tip of the circular saw blade can be high-frequency quenched to improve the quenching uniformity and effect of the circular saw blade;

[0064] After each circular saw blade is quenched, the second servo motor 33 can be used to drive the adjusting screw 34 to rotate in the opposite direction, driving the circular saw blade clamped by the reset clamp 27 to slide toward the side away from the storage bin 62. After the circular saw blade is driven to the top of the conveyor 8, the clamp 27 can be driven to separate from the circular saw blade, causing the circular saw blade to fall onto the conveyor 8 and be transported to the next processing link for subsequent processing.
