Description
Technical field
The semihard that the utility model relates to a kind of transposed conductor prolongs pressure device, belongs to the electromagnetic wire deformation technology field of colding pressing.
Background technology
Paper insulation heat bonding enamel-cover semihard transposed conductor is widely used in makes high voltage, high-power transformer winding coil, it is even to have the interior CURRENT DISTRIBUTION of coil, improves the cross-sectional area of conductor current density, reduces eddy current and circulation loss, reduce heating, improve cooling, improve advantages such as coil winding efficient.It has more characteristics such as good mechanical performance and heat bonding performance except the performance with common transposed conductor.
Present disclosed semirigid device comprises U type seat, is installed in the briquetting on the U-shaped seat, the lower pressure wheel that is installed in the upper pressure wheel on the briquetting and is installed in U-shaped seat base plate, make lead flexural deformation by upper and lower pinch roller, with the inner crystal grain rearrangement of lead, to change the lead mechanical performance, make lead reach the purpose of semihard, this semirigid device has processing characteristics simple, easy to use.But the roller both sides infinite place mechanism of the semirigid device of said structure, when lead produces skew because of tension force is irregular after, can cause the both sides of the edge part of lead to prolong to press and differ, so crystal grain is inconsistent in the middle part of the inside crystal grain of lead both sides and the lead, make the semihard quality instability of lead.Moreover semirigid device is to regulate the yield strength that the upper pressure wheel height and position comes pilot by briquetting, and when briquetting was regulated, this upper pressure wheel was all identical with radius of curvature between the lower pressure wheel, and the inner crystal grain of lead can not be realized progressively refinement.
Summary of the invention
The purpose of this utility model provides a kind of progressively refinement of the inner crystal grain of lead that makes, and the semihard that improves the transposed conductor of wire semirigid degree quality prolongs pressure device.
The utility model is that the technical scheme that achieves the above object is: a kind of semihard of transposed conductor prolongs pressure device, comprise bearing support, briquetting, prolong pinch roller and roller, it is characterized in that: described bearing support is shaped as frame, plural column is installed in the bearing support constitutes more than three independently carrier unit, briquetting more than three is installed in respectively on the lead of each carrier unit both sides, the adjusting screw(rod) more than three that is screwed in the bearing support top withstands on each briquetting respectively, each briquetting side is equipped with the more than one pinch roller that prolongs at least, the downside of bearing support is equipped with and respectively prolongs pinch roller and interlace be provided with four with upper roller, and each roller axis is in the same plane, at least the roller both sides of rear and front end have the back-up ring of evagination, respectively prolong the center line of pinch roller and the vertical range between the roller center line is successively decreased along the lead direction of advance.
The utility model adopts three independently carrier unit structures, independently all be equipped with on the carrier unit at three and prolong pinch roller, and be equipped with on the bearing support and prolong each roller that pinch roller interlaces and is provided with, the assurance lead of the back-up ring by the front and rear rolling wheel both sides can not depart from prolonging the pressure process, the inside crystal grain at lead both sides and middle part is consistent, and guarantees to prolong the pressure quality.Each briquetting of the present utility model is to be installed in respectively on each carrier unit, so height of each briquetting of energy independent regulation, and the vertical range between pinch roller center line and the roller center line is respectively prolonged in adjusting, so from the inlet wire of lead to outlet, respectively prolonging the center line of pinch roller and the vertical range between the roller center line successively decreases, because the diastrophic flexibility of lead is changed, the progressively refinement and rearranging of the inner crystal grain of lead better reaches the requirement of wire semirigid degree.The utility model can require and the calendering tolerance according to the wire semirigid degree, adjusts the vertical range of prolonging between pinch roller center line and the roller center line, and adjusting process is simple, and is easy to operate, guaranteed the yield strength of lead preferably.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Wherein: the 1-lead, the 2-bearing support, the 21-column, the 22-lead, 3-prolongs pinch roller, 4-roller, 41-back-up ring, 5-briquetting, 6-base plate, 7-adjusting screw(rod).
The specific embodiment
See shown in Figure 1ly, the semihard of transposed conductor of the present utility model prolongs pressure device, comprises bearing support 2, briquetting 5, prolongs pinch roller 3 and roller 4.The utility model bearing support 2 is shaped as frame, and being installed in the bearing support 2, plural column 21 constitutes more than three independently carrier unit, bearing support 2 is installed on the base plate 6, briquetting 5 more than three is installed in respectively on the lead 22 of each carrier unit both sides, this lead 22 adopts V-type or circle etc., to pressing guide block 5 to lead and locating, the adjusting screw(rod) more than three 7 that is screwed in bearing support 2 tops withstands on respectively on each briquetting 5, regulating each briquetting 3 respectively by each adjusting screw(rod) 7 moves up and down along the lead 22 of two of each carrier units, and regulate the height and position of each briquetting 3, the side of each briquetting 5 is equipped with the more than one pinch roller 3 that prolongs at least, prolonging pinch roller 3 is installed on the briquetting 5 by bearing and last axle, the downside of bearing support 2 is equipped with and respectively prolongs pinch roller 3 and interlace be provided with four with upper roller 4, same roller 4 is installed in the downside of bearing support 2 by bearing and lower shaft, and the axis of each roller 4 is in the same plane, at least roller 4 both sides of rear and front end have the back-up ring 41 of evagination, guarantee that lead 1 remains on respectively to prolong between pinch roller 3 and the roller 4 and pass through, along the lead direction of advance, respectively prolonging the center line of pinch roller 3 and the vertical range between roller 4 center lines successively decreases, when lead prolongs pressure through the repeatedly flexural deformation of respectively prolonging between pinch roller 3 and the roller 4, because prolonging the radius of curvature of pinch roller 3 and roller 4 bendings on each carrier unit changes, make the progressively refinement of the inner crystal grain of lead, reach the required yield strength of lead.
