Description
[technical field]
The present invention relates to a kind of structure and lubricating method of drawing copper tubes mold lubrication.
[background technology]
In non-ferrous metals processing process, the main employing of multi-pass processing is tube drawing with floating plug technique, and this technique key is in process of production in mould.Mould in use determines the quality of product quality, but most enterprises is only studied for the design of mould and the selection aspect of lubricating oil product, have ignored mould in use to the demand of lubricating system, as long as be all that simply to think that lubricating oil flows to die surface just passable, along with mould reduction of lubricating oil viscosity in drawing process causes mould in use to occur draw bead, sticky copper frequently, dryly draw phenomenon.After there is above-mentioned phenomenon, only carrying out could finding in mould maintenance, carry out replacing new die and lubricating oil product, the every block of cost of new die is at about 1000 yuan, and lubricating oil product every barrel is at about 3000 yuan.Mold defect produce the copper pipe surface defect that causes generally in drawing process along with the carrying out of production procedure, copper pipe diameter becomes more and more thinner, and wall thickness is more and more thinner, produces stealthy " sawtooth wound " defect to later process.Carry out enlarging in an assembling process and suppress, directly cause copper pipe to expand and split phenomenon, two devices are scrapped, and bring and have a strong impact on, cause the increase of operation cost of enterprises to production.
[summary of the invention]
Object of the present invention technical problem to be solved is the structure that will provide a kind of drawing copper tubes mold lubrication, its have structure simply, the performance such as safe and reliable, long service life significantly improves.Therefore, it is the product of a kind of technical, practicality and the equal top grade of economy.
This lubricating method technique is simple, high lubricating effect, to in the processing of processing copper pipe reducing, Be very effective, original jet lubrication is changed into oil and invade formula lubrication, lubrication amount can not be affected because of the reduction of lubricating oil product viscosity, while increase lubricating oil product flow, utilize the pulling capacity in drawing process to be enclosed in by lubricating oil in certain space and completely cut off entering of air, by lubricating oil by the pressure all standing in space in the lubrication district of copper pipe and mould and deformed area, along with the pressure in space can along with the progressively supercharging that accelerates of drawing speed, be more conducive to the generation of oil film, eliminate die surface draw bead, sticky copper, dry generation of drawing.
To achieve these goals, the technical solution used in the present invention: a kind of structure of drawing copper tubes mold lubrication, it is characterized in that, it comprises:
Gland, described gland built-in channel, is provided with the reducing processing die head that alloy material is made in described passage;
Retainer ring, it has the inner chamber being matched with gland, the inner chamber that described gland and retainer ring press compact siro spinning technology to immerse to form fuel feeding annular, and described retainer ring is provided with the multiple fuel feed holes communicated with described inner chamber.
Further, described fuel feed hole quantity is two, and they are symmetrical arranged.
Further, described gland is removably assembled in described retainer ring.
The invention provides a kind of lubrication side's engineering method applying the structure of above-mentioned drawing copper tubes mold lubrication, it is characterized in that, it comprises:
A. lubricating oil is circulated into inner chamber from fuel feed hole;
B. the copper pipe got ready is processed die head from reducing, make copper pipe can carry out shaping copper pipe in advance in drawing process and lubricate before entering mould prerequisite, begin to take shape drawing oil film;
C. copper pipe is carried out drawing along the direction away from reducing processing die head, copper pipe utilizes pulling capacity secondary formation oil film again in mould drawing process.
The present invention compares produced beneficial effect with background technology: present invention employs technique scheme, we improve existing lubricating system, original jet lubrication is changed into oil immersed type lubrication, lubrication amount can not be affected because of the reduction of lubricating oil product viscosity, while increase lubricating oil product flow, utilize the pulling capacity in drawing process to be enclosed in by lubricating oil in certain space and completely cut off entering of air, by lubricating oil by the pressure all standing in space in the lubrication district of copper pipe and mould and deformed area, along with the pressure in space can along with the progressively supercharging that accelerates of drawing speed, be more conducive to the generation of oil film, eliminate die surface draw bead, sticky copper, dry generation of drawing.Particularly there is outstanding effect is:
Than existing, this novel lubricating mode is beneficial to the generation of copper pipe and the oil film of mould own, the precision that improve mould itself reduces in production process because of quality problems that mold defect causes, improve the lumber recovery of itself, reduce the use cost of client and the labour intensity of employee, improve client's production efficiency; Extend the oil product replacement cycle, the labour intensity that minimizing employee changes oil and oil product are to the pollution of environment, more environmental protection; The abnormal scrap reducing mould improves die life, cost-saving; The abundance of lubrication decreases the quality problems of copper pipe itself, improves lumber recovery and utilizes the pulling capacity of equipment itself to draw supercharging not need to increase the utilization rate that supercharging equipment improves equipment, more energy-conservation.
