Description
Technical field
The utility model relates to wire production technical field, particularly relates to a kind of copper cash wire drawing die and lubricating system thereof.
Background technology
Wire rod is widely used in the departments such as communication, building, electric power.In wire production, drawing processing is the most frequently used a kind of processing mode.Wire drawing die is a kind of very important easy consumption mould during various metal wire drawing is produced, and quality and the efficiency of it and wire drawing are closely related.And in drawing process, keep good lubrication to be the key factor ensureing wire-drawing effect.The groundwork region of wire drawing die is endoporus, i.e. cable-through hole.Inner hole structure can be divided into inlet region, lubrication district, workspace, sizing area, outlet area five intervals by job specification and follow " rounding off " theoretical, and namely die channel Nei Ge district intersection is necessary for less round-corner transition.Entered wire drawing die by drawing wires from porch, by wire drawing die under the effect of pulling capacity, and on the conical surface of wire drawing die workspace, severe friction occurs, from exit pull-out, obtain thinner wire rod.The effect in lubrication district is to store lubricating fluid, and by its input service district.Wire rod enters sizing area again through workspace, it subjects larger extrusion friction power in workspace, but because the tight effect of wire rod and mould makes both be in interference fit state, lubricating fluid is difficult to enter workspace and sizing area, makes this district's lubricant effect bad.Especially workspace longer or drawing draft is larger time, the lubricating film that produces of lubrication district almost cannot reach the degree of depth position of workspace, thus forms substantial dry tension state.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of copper cash wire drawing die with better lubricant effect.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of copper cash wire drawing die, comprise line mould body, described line mould body comprises cable-through hole, described cable-through hole comprises entrance lubrication district, workspace, sizing area and outlet area from the inlet to the outlet successively, it is characterized in that, described workspace inwall is provided with the first cannelure, and described first cannelure is provided with the runner with ft connection.
The outer end of described runner is provided with hydraulic joint, the cell wall of described first cannelure and described workspace inwall arc transition.
The utility model uses like this, after online mould is in place, by fluid pressure line, the lubricating fluid through pressurizeing and described hydraulic joint are connected, high-tension lubrication liquid is made to invade on described cannelure, in described cannelure, form splash ring, play in wire rod drawing process wire rod lubrication by force again.Be particularly suitable for the wire drawing die that workspace is longer.And by regulating suitable High Pressure avoid copper cash in the bounce-back of cannelure place diameter and then form new resistance.
The beneficial effects of the utility model are: be force extruded process to wire rod in workspace, the lubricating fluid entered by lubrication zone is difficult to arrive smoothly between the wire rod of workspace and wire drawing die hole wall, force to add lubricating fluid by secondary, the lubricant effect of wire rod by cable-through hole can be improved, and then improve wire drawing quality and efficiency.Make the cell wall of the first cannelure and described workspace inwall arc transition that workspace can be avoided to form new resistance, and then avoid the surface damage to wire rod.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described sizing area is provided with the second cannelure, and described second cannelure is connected with described runner.
The beneficial effect adopting above-mentioned further scheme improves lubricant effect further, reduces drawing rub power.
Further, the degree of depth of described first and second cannelures is 0.1 ~ 0.5 millimeter, width is 1 ~ 5 millimeter.
Adopt the beneficial effect of above-mentioned further scheme to be ensure more shallow cannelure, can avoid affecting the squeezing effect of sizing section.
Further, described line mould body also comprises outer ring body, and described runner comprises radial flow path and shaft orientation flowing channel, and described shaft orientation flowing channel outlet is provided with described hydraulic joint.
The beneficial effect of above-mentioned further scheme is adopted to be that because line mould entirety is less, installation site is narrow, and runner exit being located at side can conveniently install.Outer ring body is adopted to be convenient to processing flow channel.
The utility model also provides a kind of copper cash wire drawing die lubricating system, comprise copper cash wire drawing die described in any one as above, also comprise high-tension lubrication fluid supply apparatus, described high-tension lubrication fluid supply apparatus comprises the grease-box, filter and the gear pump that are communicated with successively by pipeline, described gear delivery side of pump is provided with pressure regulating overflow valve, and described gear delivery side of pump is by valve and described flow passage.
The beneficial effect of this lubricating system is: when copper cash drawing, start high-tension lubrication fluid supply apparatus simultaneously, and regulate suitable pressure, make the lubricating oil annular high voltage that formation one is stable in cannelure substantially, due to the powerful squeezing action between copper cash and wire drawing die, the oil ring of this cannelure cannot leak substantially, but can form oil film when copper cash is passing on its surface.Play good lubrication; In addition, suitable pressure can be regulated to apply pressure to copper cash by high pressure oil ring, to avoid due to copper cash at cannelure place because extruding force rebounds, and form step resistance at cannelure place.
