Description

Technical Field

[0001] This utility model relates to the field of precision drawing machine technology, and in particular to a precision drawing machine for screw raw materials. Background Technology

[0002] In the screw manufacturing process, the screw raw material (usually metal wire) needs to undergo precision drawing to improve its dimensional accuracy and surface quality. During precision drawing, significant friction is generated between the screw raw material and the drawing die. This not only causes surface wear on the raw material but may also affect the lifespan of the drawing die, thus impacting screw production quality and efficiency. To reduce this friction, lubricating oil is typically applied to the surface of the screw raw material. However, existing lubrication methods often struggle to precisely control the amount and location of the oil, and oil leakage is a common problem during the process, increasing production costs and environmental pollution. Furthermore, existing lubrication devices are inconvenient to install and adjust, and cannot adapt to the lubrication requirements of screw raw materials of different specifications. Utility Model Content

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-4A screw raw material fine drawing machine includes a housing 1, a feeding roller 2 installed on one side of the housing 1, and a take-up roller provided on one side of the top of the housing 1. A drawing die 3 is installed inside the housing 1, and a tension wheel 4 is installed on the front side of the housing 1. An annular plate 5 is installed directly in front of the feed inlet of the drawing die 3, and a rotating plate 6 is rotatably connected to one side of the annular plate 5. A first bevel gear is installed on the surface of the rotating plate 6. At least three sleeves 7 are rotatably arranged inside the annular plate 5, and a second bevel gear 13 connected to the first bevel gear is installed on the surface of the sleeves 7. A screw 8 is threadedly connected inside the sleeves 7, and a connecting plate 9 is connected to one side of the screw 8. An oil reservoir 10 is installed on one side of the connecting plate 9, and an installation cover 11 is installed at one end of the oil reservoir 10. One side is equipped with a ball bearing 12 that contacts the screw material. Below the annular plate 5, similar components as the upper and left / right sleeves 7, screw 8, and oil reservoir 10 can also be installed. However, the oil reservoir 10 needs to have a sponge inside, soaked in oil. A piston presses the sponge to make it contact the surface of the ball bearing 12, thus also applying oil to the bottom of the screw material. One end of the mounting cover 11 has a small hole, slightly larger than the diameter of the ball bearing 12, so that the ball bearing 12 can roll freely but will not fall out. The mounting cover 11 has a groove inside that matches the shape of the ball bearing 12 to accommodate it and limit its rolling range, while ensuring a certain gap between the ball bearing 12 and the inner wall of the oil reservoir 10 so that oil can... Sufficient flow is required. The ball bearing 12 should be tightly installed in the groove of the mounting cover 11, while ensuring it can roll freely. A thin layer of grease or other low-friction material can be applied between the ball bearing 12 and the groove to reduce the resistance during rolling and prevent oil leakage from the gap between the ball bearing 12 and the groove. An elastic oil seal (such as a rubber ring or silicone ring) can be installed between the ball bearing 12 and the small hole of the mounting cover 11. The inner diameter of the oil seal should be slightly smaller than the diameter of the ball bearing 12 to ensure that the ball bearing 12 can fit tightly against the oil seal during rolling and prevent oil leakage. At the same time, the oil seal should have a certain degree of elasticity so that it can adaptively adjust its shape during rolling to maintain close contact with the ball bearing 12. The inside of the oil reservoir 10 should... Sufficient oil is stored to ensure continuous lubrication of the object surface as the balls 12 roll. Guide plates are installed at an angle inside the oil reservoirs 10 on both sides to guide most of the oil inside the reservoirs 10 to one end of the balls 12. The housing 1 contains at least two sets of annular plates 5, and the oil reservoirs 10 and balls 12 inside the annular plates 5 are staggered to facilitate oiling the screw material surface. Its working principle is roughly the same as that of a ballpoint pen. During use, the screw material passes through the tension wheel 4 and enters the annular plate 5, where it is oiled by the balls 12. The oiled screw material then enters the wire drawing die 3 for processing. When processing screw materials of different diameters, the rotating plate 6 can be rotated.The first bevel gear on its surface moves onto the surface of the second bevel gear 13, causing the second bevel gear 13 to drive the sleeve 7 to rotate. This allows the screw 8 inside the sleeve 7 to move the connecting plate 9, oil reservoir 10, and ball bearings 12, moving each ball bearing 12 to the surface of the screw material for oiling. The wire drawing die 3 is divided into an inlet zone, a compression zone, a sizing zone, and an outlet zone. The working zone is typically designed as a cone or cylinder with a gradually decreasing inner diameter, applying pressure to the wire to cause plastic deformation and thinning. The sizing zone, located after the working zone, is used to determine the final diameter of the wire.

[0016] Furthermore, a bearing 14 is installed on the surface of the sleeve 7 and is fixedly connected to the inner wall of the annular plate 5. The bearing 14 is used to support and limit the sleeve 7 and prevent shaking.

[0017] Furthermore, a movable groove 15 is provided at the bottom of the inner side of the annular plate 5, and a movable block connected to the bottom of the screw 8 is slidably connected inside the movable groove 15. This is to facilitate the screw 8, which is threaded inside the sleeve 7, to move within the movable groove 15 through the movable block when the sleeve 7 rotates.

[0018] Furthermore, connecting pipes 16 are installed on both sides of the annular plate 5, and a collar 17 is threaded onto the surface of the connecting pipe 16. A groove 18 is provided on the inner wall of the collar 17, and a slider 19 is slidably connected inside the groove 18. A connecting rod 20 is connected to one side of the slider 19, and a fixing rod 21 is connected to one end of the connecting rod 20. Fixing holes connected to the fixing rod 21 are provided on both sides of the inner wall of the housing 1. This is to facilitate the rotation of the collar 17, which allows the groove 18 and slider 19 to rotate and drive the connecting rod 20 and fixing rod 21 to move, so that the fixing rod 21 can be moved into the fixing hole, thereby allowing the annular plate 5 on one side of the connecting pipe 16 to be installed.

[0019] Furthermore, the diameter of the fixing rod 21 is the same as the inner diameter of the fixing hole, in order to avoid gaps between them, which would cause the annular plate 5 and the like to wobble.

[0020] Furthermore, the connecting pipes 16 on both sides of the annular plate 5 are not on the same straight line, in order to avoid the annular plate 5 from rotating if they are on the same straight line.

[0021] Furthermore, the surface of the connecting pipe 16 is symmetrically provided with movable grooves 22 for the movement of the connecting rod 20, which facilitates the movement of the collar 17, which can drive the connecting rod 20 to move inside the movable grooves 22.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
