Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire drawing lubricant production technology, specifically relating to a mixing device for high-efficiency production of wire drawing lubricant. Background Technology
[0002] In metal wire drawing processes (such as steel wire and copper wire drawing), wire drawing lubricant is a key auxiliary material for reducing friction between the die and the workpiece, reducing equipment wear, and improving the surface quality of the finished product. It is usually composed of multiple components such as zinc stearate (lubricant), calcium carbonate (filler), and release agent (such as calcium stearate) mixed in a specific ratio. The requirement for uniform mixing is extremely high. If the components are not evenly dispersed, it can easily lead to problems such as workpiece scratches and die overheating during the wire drawing process.
[0003] Existing wire drawing lubricant mixing devices only drive the blades to rotate through a fixed stirring shaft. For raw materials with large density differences (such as light zinc stearate and heavy calcium carbonate), a "layering and deposition" phenomenon is prone to occur, with the heavy components accumulating at the bottom and the light components floating at the top, affecting the mixing efficiency of the wire drawing lubricant. Utility Model Content
[0004] The purpose of this invention is to provide a mixing device for the efficient production of wire drawing lubricating powder, which can apply secondary vibration to the wire drawing lubricating powder raw materials to improve the mixing efficiency of the raw materials.

A mixing cylinder is installed inside the annular ring, and a material pipe is fixedly connected to one end of the mixing cylinder. A sealing mechanism is installed on the material pipe. The middle part of the mixing cylinder is a sliding part, which is slidably connected to the inside of the annular ring. The mixing cylinder is equipped with a stirring mechanism.
[0006] Furthermore, two sets of guide grooves are provided on the outer side of the mixing cylinder. The two sets of guide grooves are located on the upper and lower sides of the annular ring, respectively. There are multiple guide grooves in each set. Guide rods are fixedly connected to the upper and lower sides of the annular ring, and one end of the guide rod is slidably connected to the guide groove.
[0007] Furthermore, an annular plate is rotatably connected to the outside of the mixing cylinder and at a position in the guide groove away from the annular ring, and multiple return springs are fixedly connected between the annular plate and the annular ring.
[0008] Furthermore, the stirring mechanism includes a drive mechanism, a rotating rod, and spiral stirring blades. The rotating rod is rotatably connected to the axial position of the mixing cylinder. There are two spiral stirring blades, which are respectively fixedly connected to the two ends of the outer side of the rotating rod. The drive mechanism is installed on the outer side of the mixing cylinder, and the drive mechanism and the rotating rod are connected in a transmission manner.
[0009] Furthermore, the driving mechanism includes a first bevel gear and a transmission link. The first bevel gear is fixedly connected to one of the side plates, and the transmission link is rotatably connected to the outside of the mixing cylinder.

[0013] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0014] like Figures 1-4As shown, a mixing device for high-efficiency production of wire drawing lubricating powder includes a base plate 1. Two side plates 2 are fixedly connected to the upper side of the base plate 1. A rotating shaft 3 is rotatably connected to each of the two side plates 2. An annular ring 5 is fixedly connected between the two rotating shafts 3. A drive motor 4 that is driven by the rotating shaft 3 is fixedly connected to one of the side plates 2. By starting the drive motor 4, the annular ring 5 can be driven to rotate around the axis of the rotating shaft 3.
[0015] like Figures 1-3 As shown, a mixing cylinder 6 is installed inside the annular ring 5. One end of the mixing cylinder 6 is fixedly connected to a material pipe 7. A sealing mechanism, such as a valve or plug, is installed on the material pipe 7. During feeding, the mixing cylinder 6 is rotated so that the material pipe 7 is at the upper end, and then the sealing mechanism is opened, so that the raw material of the wire drawing lubricating powder can be added into the mixing cylinder 6 through the material pipe 7. During discharging, the mixing cylinder 6 is rotated so that the material pipe 7 is at the lower end, and then the sealing mechanism is opened, so that the wire drawing lubricating powder inside the mixing cylinder 6 can be discharged through the material pipe 7.
[0016] The middle part of the mixing cylinder 6 is a sliding part, which is slidably connected inside the annular ring 5.
[0017] like Figures 1-3 As shown, the mixing cylinder 6 is equipped with a stirring mechanism inside. When mixing the raw materials of the wire drawing lubricating powder, the drive motor 4 is started to drive the annular ring 5 to rotate, thereby causing the mixing cylinder 6 to rotate around the axis of the rotating shaft 3. At this time, under the action of gravity, the raw materials of the wire drawing lubricating powder will move back and forth between the two ends inside the mixing cylinder 6. During the movement, the mixing of the raw materials of the wire drawing lubricating powder (especially zinc stearate and calcium carbonate with large density differences) is completed, breaking the stratification of the raw materials. Since the mixing cylinder 6 is slidably connected inside the annular ring 5, when the mixing cylinder 6 slides to the limit inside the annular ring 5, the inertia and vibration force generated will apply secondary vibration to the raw materials of the wire drawing lubricating powder, thereby improving the mixing efficiency of the raw materials of the wire drawing lubricating powder.
[0018] Among them, such as Figures 1-3 As shown, two sets of guide grooves 8 are provided on the outer side of the mixing cylinder 6. The two sets of guide grooves 8 are located on the upper and lower sides of the annular ring 5, respectively. There are multiple guide grooves 8 in each set. Guide connecting rods 9 are fixedly connected to the upper and lower sides of the annular ring 5. One end of the guide connecting rod 9 is slidably connected to the guide groove 8. At this time, when the mixing cylinder 6 slides inside the annular ring 5, it will be driven to rotate to a certain extent under the guidance of the guide grooves 8 and the guide connecting rods 9. Thus, the rotation of the mixing cylinder 6 applies torque to the wire drawing lubricating powder raw material inside the mixing cylinder 6, further breaking the material stratification, thereby improving the mixing efficiency of the wire drawing lubricating powder raw material.
[0019] Among them, such as Figures 1-3As shown, an annular plate 18 is rotatably connected to the outside of the mixing cylinder 6 and at a position on the guide groove 8 away from the annular ring 5. Multiple return springs 11 are fixedly connected between the annular plate 18 and the annular ring 5. When the mixing cylinder 6 slides inside the annular ring 5, the return springs 11 can buffer the mixing cylinder 6. Then, the return springs 11 drive the mixing cylinder 6 to perform multiple gradually weakening reciprocating movements inside the annular ring 5, thereby enabling multiple vibrations to be applied to the wire drawing lubricating powder raw material inside the mixing cylinder 6.
[0020] Meanwhile, multiple positioning rods 10 are fixedly connected to the annular ring 5, the annular plate 18 and the positioning rods 10 are slidably connected, and the return spring 11 is sleeved on the outside of the positioning rod 10, so that the return spring 11 and the annular plate 18 can be limited by the positioning rod 10.
[0021] like Figures 3-4 As shown, the stirring mechanism includes a drive mechanism, a rotating rod 12, and spiral stirring blades 17. The rotating rod 12 is rotatably connected to the axis of the mixing cylinder 6. There are two spiral stirring blades 17, which are fixedly connected to the two ends of the outer side of the rotating rod 12. The drive mechanism is installed on the outer side of the mixing cylinder 6 and is connected to the rotating rod 12 in a transmission manner. At this time, the spiral stirring blades 17 on the rotating rod 12 can be driven to rotate by the drive mechanism to stir the wire drawing lubricating powder raw material inside the mixing cylinder 6.
[0022] like Figures 2-3 As shown, the drive mechanism includes a first bevel gear 13 and a transmission link 15. The first bevel gear 13 is fixedly connected to one of the side plates 2, and the transmission link 15 is rotatably connected to the outside of the mixing cylinder 6. One end of the transmission link 15 is fixedly connected to a second bevel gear 14, which meshes with the first bevel gear 13. The other end of the transmission link 15 is connected to the rotating rod 12 through a transmission group 16, which can be a belt drive mechanism or a gear drive structure.
[0023] At this time, when the mixing cylinder 6 is flipped, the first bevel gear 13 and the second bevel gear 14 can be used to convert the kinetic energy of the mixing cylinder 6 flipping into the kinetic energy of the rotating rod 12 to rotate.
[0024] In some embodiments, the drive mechanism may also be a motor fixedly connected to the end of the mixing drum 6, with the output end of the motor and the rotating rod 12 being drive-connected.
[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
