Abstract
The utility model discloses a guide barrel for a copper ball skew rolling mill, comprising an upper semicircular groove and a lower semicircular groove, wherein the upper semicircular groove and the lower semicircular groove are formed by welding a rectangular outer wall and an internally-tangent semicircular inner wall; and a layer of polyurethane material is coated-injected on the semicircular inner wall; via the guide barrel for a copper ball skew rolling mill disclosed by the utility model, the noise generated by the collision of a copper bar and the inner wall of the guide barrel is greatly decreased, and the production environment of operating personnel is ensured.
Description
Technical field
The utility model relates to a kind of skew rolling mill, is specifically related to the guide tube that a kind of copper ball skew rolling machine is used.
Background technology
Current, producing copper ball in the industry all is to adopt room temperature oblique milling technology, utilizes skew rolling mill production; The raw material that the oblique milling copper ball uses is the continuous casting copper rod that continuous metal cast process is produced; The characteristics of oblique roll process have determined that long more its utilization rate of raw material is high more, otherwise then raw-material utilization rate is low more.Therefore, in process of production, generally all be with long as far as possible continuous casting copper rod.Because the intensity of copper rod is low, crooked easily, especially length is than long copper rod; And when skew rolling mill carried out copper ball skew rolling, copper rod had both been done the straight ahead motion in drawing of skew rolling mill in the process of dragging, and did high speed rotary motion simultaneously again; Therefore, copper rod need be placed in the guide tube in fill process; On the one hand copper rod is played guide effect, also play the diastrophic effect of copper rod that prevents on the other hand.
The guide tube that existing skew rolling mill was equipped with is as shown in Figure 1, and it is made up of two parts semi-circular recesses, and semi-circular recesses is made up of 12 of rectangle outer wall 11 inscribe semicircular inner walls.Rectangle outer wall 11 uses steel system with semicircular inner walls 12, and both are integrally formed through welding, and two semi-circular recesses snap together, the inner circular trough that forms a hollow.The guide tube is when using, and normally the semi-circular recesses of lower part is fixed, and the semi-circular recesses on top opens, and the copper rod behind aligning is sent copper rod into the guide tube through feed mechanism along the axial direction of guide tube.Copper rod in the oblique milling process continuously collision guide tube inwall produce noise, if multiple devices move simultaneously, then can produce huge noise in the workshop in, severe exacerbation on-the-spot production environment, bring health hazard to the operating personnel of long-term work.
The utility model content
For solving the problems of the technologies described above, the utility model provides the guide tube that a kind of copper ball skew rolling machine is used, to realize reducing noise, improve the purpose of operating personnel's production environment.
For achieving the above object, the technical scheme of the utility model is following:
A kind of copper ball skew rolling machine is used the guide tube, comprises upper semi-circle groove and lower half circle groove, and said upper semi-circle groove and said lower half circle groove are welded by the semicircular inner walls of rectangle outer wall and inscribe, is coated with on the said semicircular inner walls and is marked with one deck polyurethane material.
Preferably, said polyurethane material thickness is 5-10mm.
Through technique scheme, copper ball skew rolling machine disclosed in the utility model is used the guide tube, is that wall is provided with one deck polyurethane material within it, to reduce the noise that the collision of copper rod and guide tube inwall is produced, has guaranteed staff's operating environment.
Description of drawings
Fig. 1 is the schematic cross-section of the disclosed a kind of copper ball skew rolling machine of prior art with the guide tube;
Fig. 2 is the schematic cross-section of the disclosed a kind of copper ball skew rolling machine of the utility model embodiment with the guide tube.
The specific embodiment
Referring to Fig. 2, this copper ball skew rolling machine comprises the upper semi-circle groove 21 and lower half circle groove 22, two semicircle groove equal and opposite in directions of steel matter with the guide tube, and both are interlocked and form a circular cavity.Upper semi-circle groove 21 all is made up of rectangle outer wall 23 and semicircular inner walls 24 with lower half circle groove 22, and semicircular inner walls 24 is inscribed within rectangle outer wall 23, and both are through the one that is welded.Be coated with the polyurethane material 25 that is marked with one deck 5-10mm on the semicircular inner walls 24, to play the effect of sound insulation.Polyurethane material is when being coated with notes, and elder generation's semicircular inner walls is provided with some apertures of irregular alignment to increase frictional force, polyurethane material is coated with annotates in the surface then, carries out baking again and handles, and die casting solidify to form inner liner.
Copper ball skew rolling machine disclosed in the utility model is used the guide tube, is that wall is provided with one deck polyurethane material within it, to reduce the noise that the collision of copper rod and guide tube inwall is produced, has guaranteed staff's operating environment.Because polyurethane material passes through the form die casting of heat on guide tube inwall, difficult coming off, result of use is good.
Claims (2)
1. a copper ball skew rolling machine is used the guide tube; Comprise upper semi-circle groove and lower half circle groove; Said upper semi-circle groove and said lower half circle groove are welded by the semicircular inner walls of rectangle outer wall and inscribe, it is characterized in that, are coated with on the said semicircular inner walls and are marked with one deck polyurethane material.
2. a kind of copper ball skew rolling machine according to claim 1 is used the guide tube, it is characterized in that, the thickness of said polyurethane material is 5-10mm.
