Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary mechanisms of wire drawing machines, in particular to an automatic powder feeding mechanism for solid lubricating powder used in wire drawing machines. Background Art

[0002] A wire drawing machine, also known as a wire drawing machine, is a machine that can draw wire rods into thin wires. It usually changes the diameter or shape of the wire rod through a rotating reel or pulley and then passes through a wire drawing die to make wires of different diameters. Since the wire drawing die needs to maintain long-term friction with the wire rod of the metal material, solid lubricant powder is usually applied to the wire rod when it enters the wire drawing die to reduce the friction coefficient between the wire rod and the die and extend the service life of the wire drawing die.

[0003] However, when the existing solid lubricant powder is added to the die box where the wire drawing die is located, since the die box is usually a rectangular structure and the lubricant powder on one side of the die inside the die box is consumed faster than the lubricant powder on the other side, the lubricant powder on the other side of the die box needs to be manually transferred to the side close to the die, which is troublesome and time-consuming to operate. If the powder is not delivered in time, it will cause irreversible damage to the wire drawing die. In addition, in order to be able to replenish the solid lubricant powder in the die box in time, the top of the die box is usually opened directly. This method easily causes the solid lubricant powder to bring up dust when the wire rod penetrates the die box at high speed, forming dust pollution, and it is also easy to cause the solid lubricant powder to fail due to moisture.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] like Figures 1 to 4As shown, the automatic powder feeding mechanism of solid lubricating powder for wire drawing machine in this embodiment includes a mold box 2, a wire feeding cylinder 1 is fixedly connected to the front of the mold box 2, a mold cylinder 10 is fixedly installed on the back of the mold box 2, a top cover 3 is engaged with the top of the mold box 2, a vertical cylinder 4 is penetrated through the top of the top cover 3, a feed hopper 5 is fixedly connected to the top of the vertical cylinder 4, a cross bar 6 is fixedly connected to the inner wall of the top of the feed hopper 5, a vertical rod 8 is movably inserted in the middle of the cross bar 6, a limit plate 9 is fixedly connected to the top of the vertical rod 8, a movable plate 7 is fixedly connected to the bottom of the vertical rod 8, a cavity 20 is opened inside the mold box 2, a rotating drum 12 is provided inside the cavity 20, first sprockets 13 are provided on both sides of the rotating drum 12, a chain 14 is meshed on the outer wall of the first sprocket 13, a belt 18 is provided at the bottom of the inner side of the cavity 20, second sprockets 17 are provided on both sides of one end of the belt 18, and rollers 19 are rotatably connected to the inner sides of both ends of the belt 18.

[0024] Specifically, the function of the wire feeding drum 1 is to limit the path of the coiled steel wire 11 entering the mold box 2, so that the steel wire 11 can be smoothly wound around the rotating drum 12 for one circle, and then pass through the mold in the mold drum 10. The mold drum 10 and the mold box 2 are detachable structures. A wire drawing die is fixed in the mold drum 10. The function of the wire drawing die is to change the diameter of the steel wire 11. The function of the top cover 3 is to facilitate the opening of the top of the mold box 2, so as to facilitate the maintenance of the belt 18 and the rotating drum 12 and other structures inside the mold box 2. The vertical cylinder 4 can play the role of temporarily storing solid lubricating powder, effectively increasing the capacity of the mold box 2. The inner diameter of the top of the feed hopper 5 is larger than the bottom, and at the same time larger than the outer diameter of the movable plate 7, so as to facilitate the solid lubricating powder to be added into the vertical cylinder 4. The function of the cross bar 6 is to maintain the connection between the vertical rod 8 and the feed hopper 5, and at the same time enable the vertical rod 8 to always be in a vertical state, so as to facilitate the movable plate 7 to slide smoothly into the vertical cylinder 4. The function of the limit plate 9 is to prevent the vertical rod 8 from The top end completely enters the interior of the vertical cylinder 4, and the outer diameter of the movable plate 7 is adapted to the inner diameter of the vertical cylinder 4, so that the movable plate 7 can cover the opening at the top of the vertical cylinder 4, thereby facilitating the vertical cylinder 4 and the interior of the mold box 2 to maintain a relatively sealed environment, reducing the probability of the solid lubricant powder in the mold box 2 getting damp, and at the same time, the bottom end of the vertical cylinder 4 is located directly above the rotating cylinder 12, so that the lubricant powder falling from the bottom of the vertical cylinder 4 can directly fall on the surface of the steel wire 11, which is beneficial for the steel wire 11 to bring the lubricant powder into the wire drawing die. The surface of the rotating cylinder 12 is smooth, and its function is to obtain rotational kinetic energy through the high-speed passing steel wire 11, thereby realizing the driving of the first sprocket 13. The direction of rotation of the belt 18 is consistent with the direction of travel of the steel wire 11 in the mold box 2, so that the belt 18 can promptly transport the lubricant powder in the mold box 2 to the side where the mold is located, thereby facilitating ensuring that sufficient lubricant powder enters the wire drawing die in time, reducing the probability of irreversible damage to the mold due to lack of lubricant powder.

[0025] Furthermore, a steel wire 11 is movably inserted into the wire feed tube 1 and the mold tube 10. The steel wire 11 is movably inserted into the mold box 2 through the wire feed tube 1. The wire feed tube 1 and the mold tube 10 are located on the same horizontal straight line, so that the steel wire 11 can remain straight when passing through the mold box 2.

[0026] Furthermore, the steel wire 11 is movably connected to the rotating drum 12 by winding, and the rotating drum 12 is rotatably connected to the cavity 20 through the steel wire 11. The steel wire 11 is wound around the rotating drum 12 for one circle and then moves into the mold drum 10, so that the rotating drum 12 can be driven by the movable steel wire 11 to generate kinetic energy, thereby realizing the driving of the first sprocket 13 by the rotating drum 12.

[0027] Furthermore, the movable plate 7 is movably connected to the feed hopper 5 and the vertical cylinder 4 respectively through the vertical rod 8. The movable plate 7 can slide down along the inner wall of the vertical cylinder 4 under the pull of the vertical rod 8, so that the remaining amount of solid lubricant powder in the vertical cylinder 4 can be marked by the height of the vertical rod 8 sliding down, thereby facilitating the user to judge whether it is necessary to add lubricant powder to the mold box 2 by checking the height of the top of the vertical rod 8.

[0028] Furthermore, a rotating column 15 passes through the middle of the rotating drum 12, and the first sprocket 13 is engaged with the rotating column 15. The first sprocket 13 is engaged with the rotating drum 12 through the rotating column 15. Both ends of the rotating column 15 are in the inner wall of the mold box 2, so that the rotating drum 12 can maintain stable rotation in the mold box 2 when driven by the steel wire 11.

[0029] Furthermore, a rotating rod 16 passes through the middle of the two rotating rollers 19, and the two ends of one of the rotating rods 16 are respectively engaged with the two second sprockets 17, and the two ends of the rotating rod 16 are also in the inner wall of the mold box 2, so that the rotating roller 19 can stably drive the belt 18 to rotate, so that the belt 18 can transfer the solid lubricant powder in the cavity 20 to the side where the mold is located, thereby ensuring that there is enough solid lubricant powder at the mold.

[0030] Furthermore, the second sprocket 17 is meshedly connected to the chain 14, and the second sprocket 17 is movably connected to the belt 18 through the roller 19, and the belt 18 is movably connected to the cavity 20 through the second sprocket 17, so that the solid lubricant powder in the mold box 2 can be automatically and quickly moved to the side where the mold is located, thereby realizing automatic powder feeding of the solid lubricant powder.

[0031] The method of use of this embodiment is as follows: when using the automatic powder feeding mechanism of solid lubricant powder for the wire drawing machine, it is necessary to first pass the end of the steel wire 11 through the wire feed drum 1, then wrap the steel wire 11 around the rotating drum 12 for one circle, and then pass the end through the mold in the mold drum 10, and then connect the end of the steel wire 11 to the traction mechanism, and then pour solid lubricant powder into the cavity 20, and close the top cover 3 tightly, and then pull the movable plate 7 to the position that fits the bottom end of the cross bar 6, and then pour an appropriate amount of solid lubricant powder into the feed hopper 5, so that the lubricant powder fills the vertical cylinder 4, and then cover the movable plate 7 on the top of the vertical cylinder 4, and then the steel wire 11 will pass through the mold box 2 at high speed under the pull of the traction mechanism, driving the rotating drum 12 in the mold box 2 to rotate. The rotating column 15 in the middle of the rotating drum 12 rotates, and the first sprocket 13 rotates, so that the first sprocket 13 meshes with the chain 14 to rotate, and the second sprocket 17 rotates, so that the second sprocket 17 drives the roller 19 to rotate, so that the belt 18 rotates, and the lubricating powder near the mold box 2 is transferred to the side of the cavity 20 close to the mold cylinder 10, so that there is enough lubricating powder at the mold cylinder 10. As the lubricating powder in the mold box is consumed, the lubricating powder in the vertical cylinder 4 will be transferred to the cavity 20. At this time, the movable plate 7 will move downward with the downward movement of the lubricating powder in the vertical cylinder 4, so that the height of the top of the vertical rod 8 changes, and the user can judge whether it is necessary to add solid lubricating powder to the mold box according to the change in the height of the top of the vertical rod 8.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
