Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wire forming, in particular to a wire cold drawing lubrication device. Background Art
[0002] Wire rod is the smallest cross-sectional size among hot-rolled steel. In my country, hot-rolled round steel with a diameter of 5 to 9 mm and eight specifications is called wire rod. Wire rod is also called wire rod because it is delivered in coils. The concept of wire rod abroad is slightly different from that in my country. In addition to the circular cross section, there are other shapes. The diameter is inconsistent due to different demand conditions and production technology levels. According to different rolling mills, it can be divided into high-speed wire rod (high-speed wire) and ordinary wire rod (ordinary wire).
[0003] Wire cold drawing is to draw the wire at room temperature to make it plastically deform, so as to improve the strength and precision of the material. The cold drawing process does not involve heating, so there is no oxide scale covering the surface of the steel.
[0004] When the wire passes through the drawing die, the interface temperature of the drawing die rises rapidly due to friction. Therefore, lubricating oil is used to cool and lubricate the wire during the metal cold drawing process to reduce friction. However, in actual operation, the lubricating oil cannot wrap the wire well, resulting in insufficient lubrication of the wire, which affects the cold drawing effect. Utility Model Content

[0016] Figure 2 It is a schematic diagram of the local enlarged mechanism at point A of the embodiment of the utility model. DETAILED DESCRIPTION
[0017] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable mechanisms and implementation methods. Therefore, the following specific implementation methods and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.
[0018] The following will be combined with the instructions attached Figure 1-2 And specific implementation methods are used to describe the above technical solutions in detail:
[0019] The utility model provides a wire cold drawing lubrication device, comprising a first shell 1, wherein a positioning mechanism and a stretching mechanism are respectively arranged in sequence in the first shell 1, through holes 2 are respectively opened on both sides of the first shell 1, a second shell 3 is rotatably connected to one side of the first shell 1, a transverse plate 4 fixedly connected to the first shell 1 is arranged below the second shell 3, a mounting seat 5 is vertically fixedly connected to the other end of the transverse plate 4, a motor 6 is fixedly connected to the mounting seat 5, an output shaft of the motor 6 is fixedly connected to the second shell 3, corresponding annular grooves 7 are respectively opened on both sides of the second shell 3, the annular grooves 7 correspond to the through holes 2, a lubrication mechanism is arranged on the second shell 3, and components of the lubrication mechanism extend into the second shell 3. When cold drawing the wire, the wire is passed through the through holes 2 on both sides of the first shell 1 and the annular grooves 7 on both sides of the second shell 3 in sequence, and then the wire is positioned and guided by the positioning mechanism, and then the wire is cold drawn by the stretching mechanism. During this process, the motor 6 drives the second shell 3 to rotate, thereby driving the lubrication mechanism to rotate together. During this process, lubricating oil can be sprayed on the outer side of the wire to avoid the problem that the wire cannot be fully lubricated due to the inability of the lubricating oil to wrap the wire well, thereby affecting the cold drawing effect. During this process, since the second shell 3 is in a relatively high-speed rotation state, the lubricating oil will hardly splash to the outside under the action of centrifugal force.
[0020] As a preferred solution, the positioning mechanism includes an upper seat 8, the upper end of which is fixedly connected to the upper inner wall of the first housing 1, and an electric push rod 9 fixedly connected to the inner wall of the first housing 1 is arranged below the upper seat 8, and the upper end of the electric push rod 9 is fixedly connected to the lower seat 10, and the lower seat 10 and the upper seat 8 are connected to the opposite end with a guide wheel 11. When the wire passes through the first housing 1 and the second housing 3, the wire is in contact with the guide wheel 11 of the upper seat 8, and then the electric push rod 9 is pushed outward to drive the lower seat 10 to move until the guide wheel 11 on the lower seat 10 also contacts the wire to complete the positioning and guiding.
[0021] As a preferred solution, the stretching mechanism includes a pressing block 12 and a wire drawing die 13 arranged on the side of the positioning mechanism close to the second shell 3. The pressing block 12 and the wire drawing die 13 are fixedly connected to the inner wall of the first shell 1 through a connecting rod, and a wire hole 14 is concentrically arranged in the center of the pressing block 12 and the wire drawing die 13. Before the wire passes through the first shell 1 and enters the second shell 3, the wire will first pass through the wire hole 14 to complete the subsequent cold drawing process through the wire hole 14.
[0022] As a preferred solution, the lubrication mechanism includes two oil tanks 15 respectively fixedly connected to the upper and lower sides of the second housing 3, the oil tank 15 is connected to an oil outlet pipe 16, the oil outlet pipe 16 extends downward into the second housing 3, and an electric control valve and a small pump body are arranged on the oil outlet pipe 16, a transverse pipe 17 is connected to the oil outlet pipe 16, and a plurality of nozzles 18 are connected to the opposite side of the two transverse pipes 17. During cold drawing, the electric control valve is opened, the lubricating oil in the oil tank 15 is pumped out by the small pump body, and sprayed out through the oil outlet pipe 16 and the nozzle 18, so as to spray the lubricating oil around the outer periphery of the wire.
[0023] As a preferred solution, the second housing 3 is provided with oil drain grooves 19 on both sides, and an oil drain pipe 20 is connected to the oil drain groove 19, and a valve is provided on the oil drain pipe 20. After the cold drawing is completed, the motor 6 stops working, the second housing 3 stops rotating, and then the valve of the oil drain pipe 20 below is opened to drain the residual lubricating oil in the second housing 3.
[0024] In order to facilitate the discharge of residual lubricating oil, as a preferred solution, the inner walls on the upper and lower sides of the second housing 3 are inclined toward the oil drain groove 19 .
[0025] As a preferred solution, a collecting tank 21 is provided below the outer end of the oil drain pipe 20. The discharged lubricating oil enters the collecting tank 21 for recovery, and can be re-added to the oil tank 15 for reuse after a series of subsequent treatments such as filtration. As a preferred solution, the collecting tank 21 can be fixed on the transverse plate 4.
