Description

Copper pipe deoiling device with brush

Technical Field

The utility model relates to a copper pipe processing field, concretely relates to copper pipe deoiling device with brush.

Background

Copper tubes are widely used in the mechanical industry and are important materials for mechanical manufacturing.

In the processing process of copper pipe stretching and the like, oil stains are usually adhered to the outer surface of the copper pipe, and in order to avoid the adverse effect of the oil stains on the subsequent process, the oil stains on the outer surface of the copper pipe are usually required to be cleaned.

In the prior art, a special external cleaning agent is mainly adopted to activate and dissolve an oil film, the adhesion between oil film molecules and a copper base is weakened, the oil film is scraped by a rubber wiper or a wiping sheet, and the oil film is dried after being scraped, so that the aim of removing oil stains on the outer surface of a copper pipe is fulfilled.

The utility model discloses a copper pipe on-line continuous cleaning device, which comprises a base, a cleaning box, a cleaning agent inlet and a cleaning agent return port, wherein a first cleaning component is arranged below the cleaning agent inlet, a guide component and a second cleaning component are coaxially arranged at two ends of the first cleaning component, and a compression component is coaxially arranged at the other end of the second cleaning component; the guide assembly, the first cleaning assembly, the second cleaning assembly and the central hole of the pressing assembly form a cleaning channel, and the minimum inner diameter of the cleaning channel is slightly larger than the outer diameter of the copper pipe; the copper pipe enters the cleaning channel through the positioning guide of the guide assembly, the pressing assembly presses the second cleaning assembly from the other end, and the copper pipe sequentially passes through the first cleaning assembly and the second cleaning assembly to perform outer surface double cleaning.

Although the online continuous cleaning device for the copper pipe can remove oil stains on the outer surface of the copper pipe, the online continuous cleaning device for the copper pipe has the following defects:

1. utilize spiral brush to realize wasing in advance as first clear subassembly can only to the copper pipe, what really play to strike off the greasy dirt is that the wiper of second cleaning assembly and compress tightly the subassembly, and first clear subassembly, second clear subassembly and compress tightly the structure that the subassembly is constituteed comparatively complicated, and the cost of manufacture is higher.

2. The copper pipe enters the cleaning device from left to right, the cleaning agent and the compressed air enter the first cleaning assembly from top to bottom to pre-clean the outer surface of the copper pipe, oil stains and the cleaning agent are pressed and then contact with the copper pipe and can run towards the left end and the right end of the copper pipe in the pre-cleaning process, and the oil stains and the cleaning agent at the right end of the copper pipe are scraped in a mode that an inner hole of the wiper radially contracts and tightly holds the copper pipe in the actual use process; when the inner hole of the wiper contracts too tightly in the radial direction, the copper pipe is difficult to move out to the right, and the copper pipe is easy to be damaged due to the too tight; when the inner hole of the conical wiper is radially contracted and loosened, the effect of completely scraping oil stains and cleaning agents on the copper pipe is difficult to achieve; the adjustment modes of the inner diameter of the wiper when the copper pipe is easy to move out and the oil stain on the copper pipe is completely scraped and the cleaning agent is completely removed are opposite, so that the two modes can not be used together.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a copper pipe deoiling device with brush, its simple structure, cost of manufacture are lower, and can carry out better cleaing away to copper pipe surface greasy dirt and cleaner under the condition of taking out the copper pipe easily.

The utility model aims to realize the purpose, and the copper pipe oil removing device with the brush comprises an inner cylinder and the brush arranged in the inner cylinder; an outer barrel is sleeved outside the inner barrel, an air knife nut which is arranged at the rear end of the inner barrel and leaves a horn-shaped gap with the inner barrel is fixed on the outer barrel, and a through hole II communicated with the inside of the inner barrel is formed in the air knife nut; a cleaning agent inlet is also formed in the outer cylinder, and an annular cavity is formed between the cleaning agent inlet and the horn-shaped gap; the inner cylinder wall and the outer cylinder wall are provided with cleaning agent outlets.
