Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, specifically to a material cutting device for processing metal springs. Background Technology

[0002] In the spring manufacturing process, cutting after winding is an important step to ensure that the final size and shape of the spring meet the design requirements. Currently, the cutting position after processing is fixed. Because the cutting position is fixed, the length of the spring tail cannot be adjusted according to the specific product requirements, which limits the adaptability of the spring in different applications. Utility Model Content

[0003] The purpose of this invention is to provide a material cutting device for metal spring processing, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material cutting device for metal spring processing, comprising:

[0005] Equipment rack;

[0006] A winding mechanism is located on the top of the equipment frame. The winding mechanism includes a rotatably mounted winding rod and a limiting baffle fixed above the end of the winding rod.

[0007] A feeding mechanism is located on one side of the winding rod. The feeding mechanism includes a linear module and a driven conveying wheel and a driving conveying wheel for conveying materials to move in the direction of the winding rod.

[0008] A cutting mechanism is placed between the linear module and the winding rod. The cutting mechanism includes a limiting plate fixed to the top of the equipment frame. A limiting groove for material conveying is opened in the middle of the limiting plate. A limiting block is adjustablely installed in the middle of the limiting plate to determine the cutting position. A cutter is slidably connected to one end of the limiting block.

[0009] Preferably, the winding mechanism further includes a second servo motor fixed to the top of the equipment frame via a metal frame, and the output end of the second servo motor is fixedly connected to a winding rod, with the gap between the limiting baffle and the winding rod forming a slot.

[0010] Preferably, a feeding duct is fixedly connected to the top of the metal frame, the air outlet of the feeding duct is directed toward the position of the winding rod, and an infrared sensor is fixedly connected to the top of the metal frame.

[0012] Preferably, a limiting block is slidably connected to the middle of the limiting plate and along the direction perpendicular to the length of the limiting plate. The middle of the limiting block has a slot that is the same as the limiting groove. A material guide groove for receiving materials is fixedly connected to one side of the limiting plate.

[0013] Preferably, the bottom of the limiting block is threaded with a threaded rod, which is rotatably connected to the limiting plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, and 7, this utility model provides a technical solution: a material cutting device for metal spring processing, comprising: an equipment frame 1; a winding mechanism located on the top of the equipment frame 1, the winding mechanism including a rotatably mounted winding rod 19 and a limiting baffle 20 fixedly connected to the upper end of the winding rod 19; a feeding mechanism located on one side of the winding rod 19, the feeding mechanism including a linear module 2 and a driven conveying wheel 6 and a driven conveying wheel 7 for conveying material to move in the direction of the winding rod 19; a cutting mechanism located between the linear module 2 and the winding rod 19, the cutting mechanism including a limiting plate 8 fixedly connected to the top of the equipment frame 1, a limiting groove 9 for material conveying is provided in the middle of the limiting plate 8, the bottom of the limiting groove 9 is at the same height as the top of the winding rod 19, a limiting block 14 is adjustablely installed in the middle of the limiting plate 8 for determining the cutting position, and a cutter 13 is slidably connected to one end of the limiting block 14.

[0026] It should be noted that in this embodiment, a controller and corresponding operation switch are provided, and the servo motors used are all equipped with encoders. The position of the limit block 14 is adjusted according to the length cut at the end of the spring, so that the distance between the connection point of the limit block 14 and the cutter 13 and the winding rod 19 is the required distance. The metal wire is passed between the driven conveying wheel 6 and the driving conveying wheel 7 in the middle of the conveying box 4, and then passed through the middle of the limiting groove 9. The driven conveying wheel 6 and the driving conveying wheel 7 transport the metal wire so that the end of the metal wire is inserted between the limiting baffle 20 and the winding rod 19. While the winding rod 19 rotates, the linear module 2 drives the conveying box 4 to convey along the limiting groove 9, thereby winding the metal wire around the outside of the winding rod 19. After winding to a suitable length, the metal wire is placed inside the limiting block 14. The cutter 13 moves up and down, thereby cutting the metal wire along the end of the limiting block 14. When the cutter 13 resets, the linear module 2 drives the conveying box 4 to move the metal wire toward the limiting baffle 20, so that the free end of the metal wire can cooperate with the limiting baffle 20 again under the conveying of the driven conveying wheel 6 and the active conveying wheel 7.

[0027] In one embodiment, the winding mechanism further includes a servo motor 2 5 fixedly connected to the top of the equipment frame 1 via a metal frame. The output end of the servo motor 2 5 is fixedly connected to a winding rod 19. The gap between the limiting baffle 20 and the winding rod 19 forms a slot. A discharge air duct 18 is fixedly connected to the top of the metal frame. The discharge air duct 18 is connected to a high-pressure air source. The air outlet of the discharge air duct 18 is directed toward the position of the winding rod 19. An infrared sensor 16 is fixedly connected to the top of the metal frame.

[0028] It should be noted that, in this embodiment, after the metal wire is placed between the limiting baffle 20 and the winding rod 19, the servo motor 25 drives the winding rod 19 to rotate, thereby winding the metal wire around the outside of the winding rod 19. After reaching the winding position, the infrared sensor 16 detects the corresponding signal and transmits it to the controller. The controller controls the cutting. After the cutting is completed, the high-pressure air source blows high-pressure air through the feeding air pipe 18, thereby blowing the formed workpiece off the outside of the winding rod 19. At this time, the servo motor 25 drives the winding rod 19 to rotate and reset under the action of the encoder, so that the limiting baffle 20 is located above the winding rod 19, which facilitates the reinsertion of the metal wire.

[0029] In one embodiment, the linear module 2 is fixedly connected to the top of the equipment frame 1, and a servo motor 3 is fixedly connected to the moving slide of the linear module 2. One end of the servo motor 3 is fixedly connected to the conveyor box 4. The driven conveyor wheel 6 is rotatably connected to the conveyor box 4, and the active conveyor wheel 7 is fixedly connected to the output end of the servo motor 3.

[0030] It should be noted that in this embodiment, metal tubes are fixed to both ends of the conveying box 4. The positions of the metal tubes and the limiting grooves 9 correspond to each other. The metal tubes pass through the middle of the driven conveying wheel 6 and the active conveying wheel 7 and enter the limiting grooves 9 under the guidance of the metal tubes. The active conveying wheel 7 is driven to rotate by the servo motor 3. Under the action of friction, the metal wire is conveyed in the direction of the winding rod 19. In conjunction with the linear module 2, the conveying box 4 is driven to move along the axis of the winding rod 19, so as to evenly wind the metal wire on the outside of the winding rod 19.

[0031] In one embodiment, a limiting block 14 is slidably connected to the middle of the limiting plate 8 and along the direction perpendicular to the length of the limiting plate 8. The middle of the limiting block 14 has a slot identical to the limiting groove 9. A material guide groove 17 for receiving material is fixedly connected to one side of the limiting plate 8. A threaded rod 15 is threadedly connected to the bottom of the limiting block 14. The threaded rod 15 is rotatably connected to the limiting plate 8. A support frame 10 is fixedly connected to the top of the limiting block 14. A lifting frame 12 is slidably connected to the outside of the support frame 10. A cutter 13 is fixedly connected to the lifting frame 12. A hydraulic cylinder 11 is fixedly connected to the top of the support frame 10. The output end of the hydraulic cylinder 11 is fixedly connected to the lifting frame 12. Two metal rods that are slidably connected to the limiting plate 8 are fixedly connected to the bottom of the limiting block 14.

[0032] It should be noted that in this embodiment, the groove of the limiting block 14 is at the same height and the same size as the limiting groove 9. When it is necessary to adjust the reserved length of the spring tail, the distance between the end of the limiting block 14 and the winding rod 19 can be adjusted. By rotating the threaded rod 15, the limiting block 14 is adjusted along the metal rod towards the winding rod 19. After the adjustment is completed, the metal wire enters the middle of the limiting block 14 along the limiting groove 9 during the winding process. Under the detection of the infrared sensor 16, the controller controls the hydraulic cylinder 11 to drive the lifting frame 12 to move vertically along the support frame 10. The lifting frame 12 drives the cutter 13 to cut downward along the end of the limiting block 14. After the cutting is completed, the hydraulic cylinder 11 drives the cutter 13 to reset. The high-pressure air blows towards the spring through the feeding air pipe 18. The spring rolls to one end to the receiving position under the partition and guidance of the guide groove 17.
