Abstract
The utility model discloses an asymmetric screw cross-slot forging die. A circular recessed groove is arranged in the middle of the upper end of the body. A cross punch is arranged at the center of the recessed groove and comprises four convex strips with inner ends connected mutually, and the adjacent convex strips are perpendicular to each other. The axes of two parallel convex strips are misaligned. The four convex strips form an asymmetric structure, a cross slot processed on a screw cap is of an asymmetric structure, a completely symmetric cross screw driver is compactly meshed when being disposed in the cross slot on the screw cap without being affected, so the cross screwdriver is not easy to slip and thorough to screw in place, work efficiency is improved and assembly waste is reduced.
Description
Technical field
The utility model relates to a kind of screw cross recess forge die, relates in particular to a kind of asymmetric screw cross recess forge die.
Background technology
Screw cross recess forge die is used for the cross recess on the processing screw cap, is one section cylinder, and its body upper center is provided with circular subsidence trough, and the center of subsidence trough is provided with for the cross recessed cross drift on the processing screw cap.Traditional screw cross recess forge die, its cross drift is the full symmetric structure, be in four raised lines of cross drift, the axis of two raised lines that are parallel to each other overlaps fully, its defective is: the cross recess of the screw that is processed into is having a little gap (for the ease of smoothly Phillips screwdriver being placed in the cross recess with the cross change of full symmetric when cooperating, must leave a little gap, generally about 0.03mm), be difficult to interlock tight, skidding is arranged when turning Phillips screwdriver, tighten and put in place thoroughly not, reduced operating efficiency, increased the assembling waste.
Summary of the invention
The purpose of this utility model provides a kind of asymmetric screw cross recess forge die with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Asymmetric screw cross recess forge die described in the utility model, its body upper center is provided with circular subsidence trough, the center of described subsidence trough is provided with the cross drift, and described cross drift comprises four interconnective raised lines in the inner, and is mutually vertical between the adjacent described raised line; In the described raised line, the axis of two described raised lines that are parallel to each other does not overlap.
Further, described raised line comprises two two sides parallel with self axis, and two described sides comprise a long limit and a minor face, and the long limit of four described raised lines all equates, the minor face of four described raised lines all equates.This structure makes the complete rule of cross recess on the screw cap of moulding.
As preferably, the distance between the axis of two described raised lines that are parallel to each other is 0.01-0.1mm, is preferably 0.01-0.5mm, and the best is 0.03mm.
The beneficial effects of the utility model are:
In the utility model, four raised lines form dissymmetrical structure, cross recess on the screw cap that processes also is dissymmetrical structure, interlock is tight when the Phillips screwdriver of full symmetric places in the cross recess on the screw cap, can't affect Phillips screwdriver and place smoothly in the cross recess, should not skid when turning Phillips screwdriver, tighten and put in place thoroughly, improve operating efficiency, reduced the assembling waste.

Fig. 1 is the stereogram of asymmetric screw cross recess forge die described in the utility model;
Fig. 2 is that the certificate of asymmetric screw cross recess forge die described in the utility model is cutd open front view;
Fig. 3 is the top view of asymmetric screw cross recess forge die described in the utility model;
Fig. 4 is the enlarged drawing of A among Fig. 3.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Such as Fig. 1-shown in Figure 4, asymmetric screw cross recess forge die described in the utility model, the upper center of its body 3 is provided with circular subsidence trough 2, the center of subsidence trough 2 is provided with cross drift 1, cross drift 1 comprises four interconnective raised lines 4 in the inner, 5,6,7, be raised line 4 between the adjacent raised line with raised line 5 between, between raised line 5 and the raised line 6, between raised line 6 and the raised line 7, mutually vertical between raised line 7 and the raised line 4; In the raised line, the axis of two raised lines that are parallel to each other does not overlap, and namely raised line 4 does not overlap with the axis of raised line 6, and raised line 5 does not overlap with the axis of raised line 7.Raised line comprises two two sides parallel with self axis, and two sides comprise a long limit and a minor face, and the long limit of four raised lines all equates, the minor face of four raised lines all equates.Among Fig. 4, the axis of raised line 4 and raised line 7 is the single-point line, and the axis of raised line 5 and raised line 6 is double dot dash line.Distance between the axis of two raised lines that are parallel to each other is 0.03mm, be that distance between the axis of raised line 4 and raised line 6 is 0.03mm, distance between the axis of raised line 5 and raised line 7 is 0.03mm, that is to say, the distance L between single-point line and the double dot dash line is 0.03mm.Among Fig. 2, for the shape of cross drift is shown, so cut the partial shell of body 3 epimeres open.The magnification ratio of the enlarged drawing among Fig. 4 is 1: 20.
In conjunction with Fig. 4, four raised lines 4,5,6,7 form dissymmetrical structures, cross recess (not shown) on the screw cap that processes also is dissymmetrical structure, interlock is tight when the Phillips screwdriver (not shown) of full symmetric places in the cross recess on the screw cap, can't affect Phillips screwdriver and place smoothly in the cross recess, should not skid when turning Phillips screwdriver, tighten and put in place thoroughly, improve operating efficiency, reduced the assembling waste.
