Abstract
The utility model discloses a kind of mold open/closing cold header to mold cam structure, including folding die holder, the longitudinal axis, the folding die holder is connected by molding the upper end circular hole of rod insertion molding swing arm, molding cam is equipped with the middle part of the longitudinal axis, the work cambered surface of molding cam is set to arc-shaped, and the arc-shaped molding roller with molding swing arm right end on molding cam matches, the upper end of the longitudinal axis is connected with bevel gear, groove position on the folding die holder is in cross, above-below direction is straight slot, left and right directions is clip slot, and flexible mould and fixing mould are separately installed with clip slot.The mold open/closing cold header molds cam structure, improves the radian of molding cam, Optimization Work face, is optimized for by original waveform arc-shaped, makes that hole distance is big, and workpiece easily drops, the work of opening for avoiding production workpiece conflicts, improving production efficiency.
Description
Technical field
The utility model belongs to cold headers technical field, and in particular to a kind of mold open/closing cold header molds cam structure.
Background technology
Cold headers are at room temperature by the forging and molding equipment of the top overstriking of bar or wire rod, are that one kind is special based on pier
Door is used for producing in batches the special equipment of the fasteners such as nut bolt.Cold headers are using the method for cold-heading by bolt, the head of screw
Portion's upsetting goes out, and can reduce cutwork to the greatest extent, is directly formed to the shape and size of needs, can not only save lot of materials, and
And production efficiency can be increased substantially, significantly improve the mechanical strength that upsetting goes out part.Therefore, in the composition mechanism of cold headers
In, each branch is very important composition.The mould open/close on cold headers is controlled by molding cam at present, convex
Wheel is fixed on longitudinal axis by expansion sleeve, and mould open/close size and time are controlled by the rotation of the longitudinal axis；Traditional molding cam
Working face radian transition circle of position arc is small, undulate, causes to mold hole position apart from less than normal, workpiece is not easy normally to drop, raw
It is low to produce efficiency.
Utility model content
The purpose of this utility model is to provide a kind of mold open/closing cold header to mold cam structure, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical solution：A kind of mold open/closing cold header molds cam knot
Structure, including folding die holder, the longitudinal axis, the folding die holder is connected by molding the upper end circular hole of rod insertion molding swing arm, described vertical
Molding cam is equipped with the middle part of axis, the work cambered surface for molding cam is set to arc-shaped, and molds the arc-shaped and molding on cam and put
The molding roller of arm right end matches, and the upper end of the longitudinal axis is connected with bevel gear.
Preferably, the groove position on the folding die holder is in cross, and above-below direction is straight slot, and left and right directions is clip slot, folder
Flexible mould and fixing mould are separately installed with groove.
The technique effect and advantage of the utility model：The mold open/closing cold header molds cam structure, improves molding cam
Radian, Optimization Work face is optimized for arc-shaped by original waveform, makes that hole distance is big, and workpiece easily drops, and avoids producing
The work of opening of workpiece conflicts, improving production efficiency.

All other embodiments obtained, shall fall within the protection scope of the present invention.
The utility model provides a kind of mold open/closing cold header molding cam structure as shown in Figs. 1-3, including open mold
Seat 1, the longitudinal axis 6, the folding die holder 1 are connected by molding the upper end circular hole of the insertion molding swing arm 5 of rod 4, and the middle part of the longitudinal axis 6 is set
There is molding cam 8, the work cambered surface of molding cam 8 is set to arc-shaped, and molds arc-shaped right with molding swing arm 5 on cam 8
The molding roller 7 at end matches, and the upper end of the longitudinal axis 6 is connected with bevel gear 9.
Groove position on the folding die holder 1 is in cross, and above-below direction is straight slot, and left and right directions is clip slot, is divided in clip slot
Flexible mould 2 and fixing mould 3 are not installed.
A kind of mold open/closing cold header molding cam structure provided by the utility model, improves the radian of molding cam 8, optimization
Working face, is optimized for arc-shaped by original waveform, is made that hole distance is big, and workpiece easily drops, is avoided opening for production workpiece
Work conflicts, improving production efficiency.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify the technical solution described in foregoing embodiments, or to which part technical characteristic
Equivalent substitution is carried out, where within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
