Abstract
The utility model discloses a flattening die of a cable connector, which comprises an upper die (7) and a lower die (8), wherein the upper die (7) is fixed on an upper template (14); an elastic stripper plate (9) is arranged on the periphery of the upper die (7); a plane flattening area (18) is arranged on the lower die (8); semicircular cavities (17) are arranged on one side or two sides adjacent to the plane flattening area (18); arc bottoms of the semicircular cavities and the plane flattening area (18) are positioned on the same plane; and the parts of a cable connector tube to be processed, which are not processed, are respectively arranged in the semicircular cavities (17). The flattening die is characterized in that a cord rod (1) is inserted in the tube which is not processed, wherein an inclined plane or an arc surface (4) is arranged at one end of the core rod (1), so that the hollow tube can be effectively supported during deformation, the length of a transitional area of the tube from circular to flat is limited and the forming precision can be improved; and in addition, a step lug (2) is formed on the core rod (1) and a small plane (3) is formed on the flange (2), so the axial movement and the radial rotation of the core rod (1) can be prevented, the deformation stability of the transitional area can be further controlled and the manufacture and use requirements of cable connector parts can be met.
Description
Technical field
The utility model relates to a kind of cable joint flattening die, relates in particular to the local mould that flattens of a kind of cable joint.
Background technology
During shaping cable joint part, before this with the local flattening of tubing, carry out other processing to flattening part again, flatten used mould and comprise patrix, counterdie, described patrix adopts the fixed head structure to be fixed on the cope match-plate pattern, patrix and cope match-plate pattern contact-making surface are hour, can between patrix and cope match-plate pattern, increase backing plate, stripper is arranged on the patrix periphery, there is a type borehole jack to go into patrix in the middle of the stripper, the design of stripper working face has the semicircle cavity, in the middle of stripper and the fixed head, it is the arranged around elastomer of patrix, cope match-plate pattern is fixed in the die shank hole on the punch press by die shank, described counterdie is fixed on the lower bolster, flattening district, plane is arranged on the counterdie, one side or both sides that adjacent plane flattens the district have the semicircle cavity, at the bottom of the circular arc of semicircle cavity with flattening district, plane coplane, the not processing part of cable joint tubing to be processed places the semicircle cavity, stripper and patrix are descending during work, under the elastomer effect, stripper is pushed down tubing not behind the processing part, patrix flattens the tubing of the processing part in flattening district, counterdie plane, tubing is freely formed the oblique angle by circle to flat transition region, this transition region is irregular, interchangeability is poor, influence the cut-out and the forming process of back, the more important thing is that transition region is oversize sometimes, lead can't insert specific length during back operation crimping, transition region is oversize simultaneously can increase resistance value, influences the quality of connection and the use of cable joint and cable conductor.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of cable joint flattening die that can control the transition region distortion.
For solving the problems of the technologies described above, a kind of cable joint flattening die of the present utility model, it is characterized in that: also comprise plug, described diameter of mandrel is slightly less than the cable joint pipe internal diameter, one end is made the inclined-plane, beveled end is inserted tubing, in the processing, to flat transition region, described counterdie has the recessed groove perpendicular to semicircle cavity axis to inclined-plane restriction cable joint tubing by circle, and described plug has a step ledge, flange width is slightly less than the recessed groove width, the flange of plug places recessed groove, and the flange of described plug is shaped on a plane, and described recessed groove bottom surface is the plane.
The utility model has following good effect than prior art.A kind of cable joint flattening die of the present utility model, make the plug on inclined-plane by increasing by an end, can make hollow tubing when distortion, obtain secure support, improved cable joint part forming precision, specific chamfer length has limited the length of transition region, the step ledge of making on the plug in addition, place the recessed groove of counterdie, prevented that plug from moving axially, and fit in facet of making again on the flange and recessed groove bottom surface, further limit plug and radially rotated, can further control the transition region deformation stability so like this, satisfied the manufacturing and the instructions for use of cable joint part.
