Description
Technical field
The utility model belongs to wire-drawing die field, is specifically related to a kind of wire drawing die head with cooling device.
Background technology
Wire drawing is a kind of material processing method of extensive use in materials processing industry, wire drawing is as its name suggests becomes fine rule by pulling force by thick line drawing, wire drawing generally includes metal wire-drawing and plastic wire-drawing, in drawing process, distortion can be produced from the coarse to fine by drawn wire, and the distortion of material can be generated heat along with material, for metal wire-drawing, if do not do the performance that cooling processing can affect fine wire after metal wire drawing heating, and metal wire drawing rear surface temperature is higher, cool timely if do not do, have the danger of scalding other people.Existing wire drawing cooling is normally sprayed cooling water directly to the exit of drawing-die or is cooled wire by lubricant, but also contain corrosion composition because cooling water all contains a large amount of impurity usually in lubricant, when cooling water or lubricant directly contact with wire, can pollute, corroding metal silk, especially under the state that wire is in high temperature, molecular thermalmotion speed in wire is accelerated, cooling water and impurity thereof or lubricant and corrosion composition thereof is easily caused to infiltrate wire inner, affect the performance of fine wire, reduce drawing quality.In addition, adopt cooling water directly sprinkling can make cooling water splashes and be unfavorable for recycling, affect site environment, waste resource, and adopts lubricant to carry out cooling fluid to make that lubricant is sticky to be sticked and be unfavorable for recycling everywhere.
Utility model content
The technical problems to be solved in the utility model can reduce drawing quality for existing wire drawing cooling, affects the technological deficiency that site environment and cooling medium can not recycle, and provides a kind of and can not reduce drawing quality, can not affect the wire drawing die head of site environment and the recycled band cooling device of cooling medium.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: the wire drawing die head of band cooling device, and comprise die head, be provided with drawing pass in die head, described die head comprises hard alloy layer and red copper layer from the inside to the outside successively; Also comprise cooling device, cooling device comprises cooling layer and shell from the inside to the outside successively, described cooling layer comprises cooling tube, described cooling tube is coated on red copper layer outer wall, and described shell is square iron shell, and shell and die head end form closed cavity, also thermal insulation layer is provided with in cavity, described thermal insulation layer is asbestos packed layer, and outer casing end is provided with the through hole communicated with drawing pass, and cooling tube two ends extend to outside shell through thermal insulation layer and shell all successively.
Adopt the wire drawing die head of the band cooling device of technical solutions of the utility model, comprise die head, die head is main body of the present utility model, makes by drawn wire drawing forming, drawing pass is provided with in die head, when carrying out wire-drawing operation, heavy wire is passed drawing pass, is become fine wire by drawing pass sidewall extrusion under a stretching force.Described die head comprises hard alloy layer and red copper layer successively outside interior, hard alloy layer hardness is large, intensity is high, can crimp be carried out to heavy wire and self can not produce distortion, the thermal conductivity factor of red copper layer is high, deposit in case at hard alloy layer and cooling layer thermograde, red copper layer can make to extrude the heat produced and be passed to cooling layer by sidewall rapidly, and the intensity of red copper layer is high, and red copper layer also can ensure the intensity of die head while ensureing heat-transfer rate faster.Also comprise cooling device, cooling device cools die head and wire, is connected with the cooling medium of low temperature in cooling tube, make to produce thermograde between wire and cooling layer, thus the heat that extruding is produced is passed to cooling layer from hard alloy layer; Cooling tube is coated on red copper layer outer wall, make the contact area of cooling tube and red copper layer outer wall large, increase cooling effectiveness, shell can protect cooling layer not damage by extraneous, and the shell intensity of iron shell is large, thermal conductivity factor is low, thus shell is better to the protected effect of cooling layer, and also can reduce the uptake of cooling medium heat to external world; Thermal insulation layer is located between cooling layer and shell, and can reduce the uptake of cooling medium heat to external world, asbestos thermal conductivity factor is low, can realize heat insulation preferably; Through hole on outer casing end communicates with drawing pass, thus wire can enter in drawing pass through through hole; It is outer and be connected with EGR respectively that cooling tube two ends extend to shell through thermal insulation layer and shell all successively, realizes recycling of cooling medium.
Know-why of the present utility model and technique effect are: cooling tube is wound in the outer wall of red copper layer, the cooling medium of low temperature is connected with in cooling tube, hard alloy layer extrusion metal silk, make wire be out of shape heating, thus temperature wiry raises, namely larger thermograde is produced between wire and cooling medium, thus drawing pass and wire extrude the heat produced can pass to cooling medium rapidly, realize wiry cooling.Due in whole cooling procedure, cooling medium is cooling Bottomhole pressure always, and does not directly contact with wire, avoids cooling medium and directly contacts with wire and make cooling medium can not pollute wire, ensure that drawing quality wiry; Because cooling medium is realizing also not contacting with external environment in cooling procedure, avoids cooling medium splashes and affecting environment; Cooling medium is at cooling Bottomhole pressure, and cooling tube two ends are all connected with extraneous EGR, achieve recycling of cooling medium, avoid the waste of resource.
Further, described cooling tube is helically wound around on red copper layer.Thus cooling tube and die head can be made to fit closely, and spiral winding makes the contact area of cooling tube and die head outer wall large, and then make the cooling effect of cooling tube better.
Further, the cross section of described cooling tube is rectangle.Cross section is that rectangular cooling tube can strengthen the laminating degree of cooling tube and die head outer wall further, increase the contact area of cooling tube and die head outer wall, strengthens cooling effect.
Further, described shell is provided with the tampon tube communicated with cavity, and tampon tube is provided with seal cover tampon tube conveniently can insert asbestos, heat insulation to realize.
Further, described tampon tube has two, and described two tampon tubes lay respectively at the both sides of die head.The both sides up and down of shell are respectively equipped with tampon tube, convenient are filled in by asbestos in whole cavity that shell and die head end formed.
Further, described shell comprises shell and lower casing, is provided with clamping screw between upper shell and lower casing.Thus can conveniently install.
