Abstract
The utility model relates to improvement on a structure of a cam mechanism. The utility model provides a rotary cam mechanism which is of simple structure and is capable of expanding an application range the cam. The rotary cam mechanism of the utility model comprises a rack and a concave die arranged therein. The rotary cam mechanism is characterized in that the concave die in a cylindrical shape; the concave die is arranged inside a cylindrical cavity in the rack; and the concave die is connected with a reset rotary mechanism.
Description
Technical field
The utility model relates to a kind of improvement of Wedge mechanism structure.
Background technology
The range of application of Wedge mechanism has certain limitation, can only be applied to side blow hole, side deburring, side flanging, and does not have on the side mould of negative angle, and on the side mould of negative angle, and the taking-up of product is caused great difficulty, can't use.In the automobile die manufacture process, a lot of large-scale coverings is arranged, because product profile more complicated, the integral forming technique of consideration product, locally-shaped and punching press coordinate system are that the situation of negative angle forming is a lot; If consider the difficulty of negative angle moulding separately, then need the moulding of product gyration can be increased the quantity of mould like this, or increase the size of mould; The cost of mould development and the pressing cost of stamping parts are than higher.
Summary of the invention
The utility model is exactly to the problems referred to above, provides a kind of simple in structure, can expand the rotation Wedge mechanism of Wedge mechanism range of application.
For realizing the above-mentioned purpose of the utility model, the utility model adopts following technical scheme, and the utility model comprises frame, is provided with die in the frame, and the described die of its structural feature is a cylindricality, and die is arranged in the cylindrical cavity in the frame; Said die links to each other with the rotating mechanism that resets.
The beneficial effect of the utility model: 1, the utility model links to each other die with the rotating mechanism that resets, and simple in structure, production cost is low.
When 2, the utility model is faced the situation of negative angle forming,, make die overcome angle of elastic force rotation of tension spring through the cooperation of punch and die; After treating Workpiece shaping, tension spring reverse rotation die breaks away from die and workpiece again, and workpiece can directly take out; Thereby expanded the range of application of Wedge mechanism, reduced the cost of mould and stamping parts compacting, improved production efficiency.
3, the utility model can adapt to the situation of multiple negative angle forming, can be widely used in mould manufacturing field.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of an embodiment of the utility model.
1 is that tension spring, 2 is that frame, 3 is that die, 4 is punch in the accompanying drawing.
The specific embodiment
The utility model comprises frame 2, is provided with die 3 in the frame 2, and described die 3 is a cylindricality, and die 3 is arranged in the cylindrical cavity in the frame 2; Said die 3 links to each other with the rotating mechanism that resets.
Embodiment 1: the described rotating mechanism that resets comprises the tension spring 1 of horizontally set, and an end of tension spring 1 links to each other with frame 2, and the other end of tension spring 1 links to each other with die 3 bottoms.
Before the mould matched moulds, tension spring 1 shrinks, and die 3 is rotated counterclockwise.During the compacting product, the mould matched moulds, punch 4 contacts with die 3, drives die 3 and turns clockwise, and tension spring 1 is elongated.When the product compacting is accomplished, the mould die sinking, after punch 4 broke away from die 3, die 3 was rotated counterclockwise under the effect of tension spring 1 convergent force, and moulding negative angle place breaks away from product, and product can directly take out.
Embodiment 2: the described rotating mechanism that resets comprises the cylinder in the frame 2, and the piston rod of cylinder links to each other with die 3 bottoms.
During the mould matched moulds, cylinder drives die 3 through piston rod and is rotated counterclockwise.When the product compacting is accomplished, the mould die sinking, after punch 4 broke away from die 3, die 3 was rotated counterclockwise under the effect of cylinder, and moulding negative angle place breaks away from product, and product can directly take out.
Claims (3)
1. a rotation Wedge mechanism comprises frame (2), is provided with die (3) in the frame (2), it is characterized in that: described die (3) is cylindricality, and die (3) is arranged in the cylindrical cavity in the frame (2); Said die (3) links to each other with the rotating mechanism that resets.
2. a kind of rotation Wedge mechanism according to claim 1; It is characterized in that: the described rotating mechanism that resets comprises the tension spring (1) of horizontally set; The same frame of one end (2) of tension spring (1) links to each other, and the same die of the other end (3) bottom of tension spring (1) links to each other.
3. a kind of rotation Wedge mechanism according to claim 1 is characterized in that: the described rotating mechanism that resets comprises the cylinder in the frame (2), and the same die of the piston rod of cylinder (3) bottom links to each other.
