Technical Field

[0001] The utility model relates to the field of seamless steel pipe processing, in particular to a device for cleaning lubricating powder on the outer wall of a cold-drawn steel pipe. Background Art

[0002] Cold drawing is an important steel pipe processing technology, which can improve the surface quality of steel pipes, and increase the dimensional accuracy and strength of steel pipes. Cold-drawn steel pipes will be subject to great friction and impact during the drawing process, which requires the help of lubricants to reduce friction and damage, while also ensuring the surface quality of the steel pipes. Therefore, operators need to lubricate the outer wall of the steel pipe before cold drawing.

[0003] The most common treatment method is to coat the steel pipe surface with steel pipe drawing lubricant powder. However, a considerable amount of lubricant powder still remains on the outer surface of the steel pipe after cold drawing. In order to remove the residual lubrication, the steel pipe surface needs to be pickled. If the residual lubricant powder on the steel pipe surface is high, a large amount of pickling liquid is required, which increases the production cost. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-5 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] like Figures 1 to 5 As shown, the utility model discloses a lubricating powder cleaning device for the outer wall of a cold-drawn steel pipe, comprising an operating table 1, one end of which is fixedly connected to a mounting frame 11, and a through pipe 12 for the seamless steel pipe to pass through is fixedly connected to the mounting frame 11. Further, the operating table 1 is fixedly connected to a workroom 2 on one side of the through pipe 12, a cleaning cavity 21 is provided in the workroom 2, a blower 3 is fixedly connected to the upper end of the cleaning cavity 21, and a side cleaning mechanism is symmetrically arranged on the side wall of the cleaning cavity 21; further, a dust collecting box 22 is fixedly connected to the bottom end of the cleaning cavity 21, the workroom 2 is fixedly connected to dust blocking curtains 4 on both sides of the cleaning cavity 21, and the operating table 1 is fixedly connected to a lower cleaning mechanism on one side of the cleaning cavity 21.

[0024] The side cleaning mechanism includes a rotating cylinder 51 and a cleaning brush 52. The specific structure of the side cleaning mechanism is as follows: a mounting seat 23 is fixedly connected to the inner side wall of the cleaning chamber 21, the rotating cylinder 51 is fixedly connected to the mounting seat 23, the cleaning brush 52 includes a connecting rod 53, the connecting rod 53 is fixedly connected to the piston rod of the rotating cylinder 51, and the cleaning brush 52 is oriented toward the central axis of the cleaning chamber 21.

[0025] When the steel pipe passes through the dust-blocking curtain 4 and enters the cleaning chamber 21, the strong airflow blown out by the hair dryer 3 at the top of the cleaning chamber 21 blows off the lubricating powder on the upper end of the steel pipe, and at the same time, the rotating cylinder 51 drives the cleaning brush 52 to rotate, thereby cleaning the lubricating powder on the side of the steel pipe, and sweeping the lubricating powder blown off from the upper end of the steel pipe into the dust collecting box 22, thereby cleaning the lubricating powder on the side and upper end of the steel pipe.

[0026] Furthermore, since the hair dryer 3 and the cleaning brush 52 will raise a large amount of dust when cleaning the steel pipe, it is not only not conducive to cleaning the site, but also affects the health of the operators. Therefore, the utility model has dust curtains 4 fixedly connected at both ends of the workshop 2, and a through hole 41 is opened at the center position of the dust curtain 4 for the steel pipe to pass through, and in order to adapt to the size of the steel pipe, the dust curtain 4 is provided with a plurality of deformation gaps 42 on the outer edge of the through hole 41. If the outer diameter of the steel pipe is larger than the aperture of the through hole 41, the through hole 41 can be expanded and deformed to allow the steel pipe to pass through when the steel pipe penetrates the dust curtain 4.

[0027] Furthermore, in order to solve the problem of dust collection, a felt blanket 24 is laid at the bottom of the dust box 22. Since the surface of the felt blanket 24 is relatively rough, the dust will adhere to the surface of the felt blanket 24 after falling into the dust box 22, and will not be lifted by the airflow and scattered in the cleaning chamber 21 during the cleaning operation, thereby avoiding secondary contamination of the steel pipe surface.

[0028] After the steel pipe surface is cleaned by the hair dryer 3 and the cleaning brush 52, there is still a little lubricating powder remaining at the lower end of its outer wall, so the lower end cleaning mechanism is required to further clean the outer wall of the steel pipe. In this embodiment, the lower end cleaning mechanism includes a cleaning roller 6 driven by a motor, and the specific connection method of the cleaning roller 6 is: the operating table 1 is fixedly connected to a connecting seat 13 on the side of the workroom 2 away from the through tube 12, and the cleaning roller 6 is rotatably connected to the connecting seat 13. A cleaning groove 61 is opened at the center of the outer wall of the cleaning roller 6. In addition, the outer wall of the cleaning roller 6 is wrapped with adsorption cotton 62, and a number of adsorption magnets 63 are fixedly connected to the cleaning groove 61. The side of the adsorption cotton 62 that fits the cleaning groove 61 is fixedly connected to a metal strip 64, and the adsorption cotton 62 is fixedly connected to the adsorption magnet 63 through the metal strip 64, thereby ensuring that the adsorption cotton 62 can fit the cleaning groove 61.

[0029] After the steel pipe leaves the workroom 2, its lower end contacts the cleaning groove 61 when passing through the cleaning roller 6, so that the lower half of the steel pipe sinks into the cleaning groove 61, thereby ensuring that the lower end of the steel pipe can fully contact the cleaning roller 6. During the contact between the steel pipe and the cleaning roller 6, the adsorbent cotton 62 on the surface of the cleaning roller 6 will take away the lubricating powder remaining at the lower end of the steel pipe.

[0030] It should be noted that tightening bands (not shown) are provided at both ends of the adsorption cotton 62 in this embodiment. When the adsorption cotton 62 is wrapped around the outer surface of the cleaning roller 6, the tightening bands can be used to fix the adsorption cotton 62 to prevent it from falling off the cleaning roller 6. When the amount of lubricating powder adsorbed by the adsorption cotton 62 reaches a certain amount, the operator can remove the old adsorption cotton 62 for replacement.

[0031] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
