Abstract
The utility model relates to the die structure controlling automotive hinge riveting molding head sizes, connect the first workpiece and second workpiece, the bearing pin comprising die and be connected with die, die is the structure of concave shaped, bearing pin is step structure, size matches with the through hole offered on the first workpiece and second workpiece respectively, connects the first workpiece and second workpiece.Compared with prior art, riveted joint head forming surface diameter of the present utility model and highly meeting the demands, riveting the speed pressed down and the stroke pressed down by regulating, can also regulate the height of shaping head.
Description
Technical field
The utility model relates to a kind of die structure, especially relates to the die structure controlling automotive hinge riveting molding head sizes.
Background technology
Riveting machine is according to cold rolling principle, and die only contacts a some region of workpiece at every turn, makes it distortion under less pressure effect, then by swinging, deformed region is expanded to whole distortion section, thus completes the distortion of whole end face.As long as make suitable die during use, can rivet out different shapes, often kind of shape die size is finely tuned slightly simultaneously, can debug out diameter and the requirement for height of bearing pin head.The riveting segment length dimension of bearing pin and the shape of riveter die determine two key factors of shaping head sizes, how to realize accurate control, and this is also one of this area technical problem urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is exactly provide a kind of die structure of control automotive hinge riveting molding head sizes of riveting head forming surface diameter and highly meeting the demands to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
Control the die structure of automotive hinge riveting molding head sizes, connect the first workpiece and second workpiece, the bearing pin comprising die and be connected with die, described die is the structure of concave shaped, described bearing pin is step structure, size matches with the through hole offered on the first workpiece and second workpiece respectively, connects the first workpiece and second workpiece.
The contact surface place of described bearing pin and the first workpiece and second workpiece is also provided with liner layer.
Described liner layer is made up of the lining lubricating layer of inner side and the bush metal layer in outside.
Described die and the upper surface of the first workpiece are that face contacts.
Compared with prior art, riveted joint head forming surface diameter of the present utility model and highly meeting the demands, riveting the speed pressed down and the stroke pressed down by regulating, can also regulate the height of shaping head.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be die, 2 be second workpiece for bearing pin, 3 is the first workpiece, 4,5 be lining lubricating layer, 6 for bush metal layer.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
Control the die structure of automotive hinge riveting molding head sizes, its structure as shown in Figure 1, be mainly used in connection first workpiece 3 and second workpiece 4, the bearing pin 2 comprising die 1 and be connected with die 1, die 1 is the structure of concave shaped, bearing pin 2 is step structure, and size matches with the through hole offered on the first workpiece 3 and second workpiece 4 respectively, connects the first workpiece 3 and second workpiece 4.Die 1 is that face contacts with the upper surface of the first workpiece 3, more than the size 2-3mm at least contacted.Bearing pin 2 and the first workpiece 3 are also provided with liner layer with the contact surface place of second workpiece 4, and this liner layer is made up of the lining lubricating layer 5 of inner side and the bush metal layer 6 in outside.The lubricating layer of lining is uniformly distributed, and does not allow to peel off with bush metal layer.Size aspect, riveted joint head forming surface diameter and highly meeting the demands, terms of mechanics, axis direction is made the head axis ejecting force that power meets the riveting molding talked about in front cover for vehicle testing standard TL82436--6.1 and is required >=14.5KN.
