Abstract
The utility model discloses an Oil pump of dance wiredrawing oil circulation system, which comprises a pump body and a base, wherein a hollow detachable abrasion resistant sleeve is embedded in the inner cavity of the pump body, the abrasion resistant sleeve is distributed close to the inner wall of the pump body, the exterior shape of the abrasion resistant sleeve and the shape of the inner cavity are the same to the shape of the inner cavity of the pump body, the size of the abrasion resistant sleeve is matched with the size of the inner cavity of the pump body; a through hole is arranged on the abrasion resistant sleeve corresponding to the feeding port of the pump body. The oil pump of dance wiredrawing oil circulation system has simple structure, good abrasion resistance, high durability and convenient maintenance, and has low maintenance cost and is very applicable to high-speed wire drawing benches.
Description
Technical field
The utility model relates to electric wire, electrical cable-making apparatus, refers to a kind of loop type wire drawing oil circulating system oil pump particularly.
Background technique
When making lead series products such as electric wire, cable, need use the high-speed wire-drawing machine, and the conductive line surfaces quality is by the oil pump decision of wire drawing oil circulating system in the drawbench.As shown in Figure 1, the pump housing of existing wire drawing oil circulating system oil pump all adopts the cast iron cast inblock to form, and the pump housing is a hollow, and inside is provided with for the cavity of placing gear.When drawbench is worked, as time passes, wire drawing well cuts content can increase gradually, oil viscosity also can increase thereupon, the pressure that makes wire drawing oil produce in oil pump strengthens gradually, causes pump housing internal gear transmission shaft bending, and the tooth top of gear can come in contact with the internal chamber wall of the pump housing, produce friction, wearing and tearing pump housing inwall.When the wearing and tearing of general pump housing inwall reached 0.2mm～0.3mm, oil pump just can't normally use, and needs to be serviced.And the oil pump of employing existing structure because the pump housing is a cast-in-block, and adopts cast iron as material, use when frequent at drawbench, just needed to safeguard once in general 1 to 2 months, after the pump housing inner wall abrasion, pump housing inwall can't be repaired, and whole oil pump can only be changed.Change the thousands of at least units of a table oil pump, tens thousand of at most units, and also operation is very complicated, and annual maintenance cost number is huge, has greatly increased the cost of production of enterprise.
Summary of the invention
The purpose of this utility model will overcome the existing deficiency of above-mentioned background technology exactly, and a kind of simple in structure, durability degree is high, maintenance is convenient and maintenance cost is low loop type wire drawing oil circulating system oil pump is provided.
For achieving the above object, the loop type wire drawing oil circulating system oil pump that the utility model is designed, include the pump housing and base, be equipped with the wear-resistant sleeve of dismountable hollow in the inner chamber of the described pump housing, described wear-resistant sleeve is close to pump housing internal chamber wall and is arranged, all the cavity shape with the pump housing is identical for the shape of its external shape and inner chamber, its outer surface size and pump housing inner cavity size coupling; Material feeding mouth corresponding part with the pump housing on the wear-resistant sleeve offers through hole.
Further, for strengthening wear resistance, improving durability degree, said wear-resistant sleeve is the lining of Wear Resisting Steel material.
Further, for ease of loading and unloading, described wear-resistant sleeve is by to being much of sleeve pipe and casing running is spliced, and describedly goes up sleeve pipe and casing running is the cylinder-shaped sleeve that outer wall is provided with the grooved opening.
Advantage of the present utility model is: the pump housing of the whole iron casting of original employing has been changed into by the pump housing and the wear-resistant sleeve of being close to pump housing internal chamber wall constitute jointly, set up one deck wearing layer, effectively improved the durability degree of oil pump; Simultaneously, wear-resistant sleeve is detachable structure, after wearing and tearing, directly parts such as wear-resistant sleeve that more renews and gear, gear shaft get final product, and need not the oil pump integral replacing, and the replacement cost of all parts is less than 500 yuan, it is convenient not only to safeguard, and has greatly reduced the cost of safeguarding.

Embodiment
Be described in further detail of the present utility model below in conjunction with accompanying drawing and instantiation:
Existing wire drawing oil circulating system oil pump as shown in Figure 1 is described in background technique, repeats no more in this.
As Fig. 2～shown in Figure 4, the loop type wire drawing oil circulating system oil pump that the utility model is designed includes the pump housing 1 and is fixedly connected on the base 2 of the pump housing 1 bottom, and the described pump housing 1 is provided with material feeding mouth 4.Be equipped with a wear-resistant sleeve 3 at the pump housing 1 inner close fitting internal chamber wall, described wear-resistant sleeve 3 is identical with the cavity shape of the pump housing 1, and size also is complementary with the inner cavity size of the pump housing 1, offers through hole 5 in the position of its corresponding material feeding mouth 4.Wear-resistant sleeve 3 is the hollow lining, is provided with the inner chamber that is used to arrange oil pump gear in it, and the shape of inner chamber is identical with the inner chamber of the pump housing 1.Described wear-resistant sleeve 3 is the wearing layer that is provided with in the pump housing 1, and is detachable between wear-resistant sleeve 3 and the pump housing 1, after wear-resistant sleeve 3 weares and teares, directly unloads, changes and can guarantee oil pump proper functioning again.Be further to improve durability degree, described wear-resistant sleeve 3 with the high-quality steel as material.
For ease of dismounting, described wear-resistant sleeve 3 is by to being much of sleeve pipe 3a and casing running 3b is spliced.Last sleeve pipe 3a is identical with the shape of casing running 3b, is the cylinder-shaped sleeve that outer wall is provided with the grooved opening, offers the through hole of semicircle respectively in last sleeve pipe 3a and casing running 3b and material feeding mouth 4 corresponding parts.The two opening is spliced into the integral body of a closure relatively, and the through hole of two semicircles is formed the manhole 5 that matches with material feeding mouth 4.
Embodiment:
Cylinder iron, adopt the cast-in-block mode to produce the pump housing 1 that intracavity diameter is 100.022mm as material.With the wear-resisting steel of high-quality is two outer diameter 100mm of material, the steel pipe of inner diameter 86.5mm; With the steel pipe horizontal, along continuous straight runs cuts out the grooved opening at the downward 37.5mm of distance steel pipe center line place, and gets out the semicircle orifice that radius is 22.5mm respectively along the middle part on the tube wall of opening both sides; Make sleeve pipe 3a and casing running 3b through said process.To go up sleeve pipe 3a and casing running 3b splicing becomes wear-resistant sleeve 3, is embedded in the inner chamber of the pump housing 1, and assembling cogs, gear shaft and remaining part, just makes the loop type wire drawing oil circulating system oil pump of internal diameter 86.5mm.
