The invention discloses a bending die with split female dies. The bending die with the split female dies can be used for forming V-shaped pieces of different shapes and different bending degrees. The bending die comprises a male die capable of moving up and down; a protruding V-shaped face is arranged at the lower end of the male die; the female dies are arranged under the male die and comprise the first female die and the second female die which are oppositely arranged; the first female die is fixedly arranged; the first female die and the second female die are provided with a first threaded hole and a second threaded hole respectively; the first female die and the second female die are opposite in position, and the rotating direction of the first female die and the rotating direction of the second female die are opposite; a screw rod is connected to the interior of the first threaded hole and the interior of the second threaded hole through threads; a first bevel is arranged on the upper portion of the first female die; a second bevel is arranged on the upper portion of the second female die; and a V-shaped groove is formed between the first bevel and the second bevel.

Description

Adopt the bending die of split type die
Technical field
The present invention relates to bending mould technical field, be specifically related to a kind of bending die adopting split type die.
Background technology
Bending die is mainly used in automobile panel, the brake forming of the parts such as support element, typical bending die comprises V-arrangement part bending die, the primary structure of V-arrangement part bending die comprises the punch that can move up and down, the lower surface of punch is the V-arrangement face of protruding, be positioned at immediately below punch is die, die is arranged on die shoe, the top of die is the V-shaped groove of the depression of mating with the lower surface size of punch, time shaping, smooth blank is placed on die, punch presses down, blank is pressed in the V-shaped groove of die depression, mold V-arrangement part, this bending die Problems existing is: the size of the V-shaped groove of die is fixing, therefore a kind of mould can only mold the V-arrangement part of a kind of shape and flexibility usually, practical limitation is large.
Summary of the invention
The invention is intended to provide a kind of bending die that can be used for the split type die of the V-arrangement part of shaping difformity and flexibility.
The bending die of the split type die of the employing in this programme, comprise the punch that can move up and down, the lower end of punch has the V-arrangement face of protrusion, die is provided with immediately below punch, die comprises the first die and the second die that are oppositely arranged, first die is fixedly installed, first die and the second die have the first screwed hole and the second screwed hole, first screwed hole is relative with the second screwed hole position and rotation direction is contrary, a screw rod is connected with at the first screwed hole and the second screwed hole internal thread, first die top has the first inclined-plane, second die top has the second inclined-plane, V-shaped groove is formed between first inclined-plane and the second inclined-plane.
The invention has the advantages that: die adopts split type, namely die includes the first die and the second die, and the first die is fixedly installed, first die is connected by screw rod with the second die, and the thread rotary orientation of the first die and the second die is contrary, therefore rotating screw bolt, just can force the second die relative to the second die away from or close, thus regulate the size of the V-shaped groove between the first inclined-plane and the second inclined-plane, after being adjusted to required size, mold required V-arrangement part by the cooperation punched blank of punch and die.By the bending die of this programme plastic go out the V-arrangement part of difformity and flexibility, possess larger practicality.
Further, also comprise die shoe, die shoe top has a gathering sill, and the first die and the second die are all positioned at gathering sill.The gathering sill of die shoe, has the effect of motion guide to it when the relative first die motion of the second die.
Further, first die and the second die top also have the first plane and the second plane respectively, the first pressing plate and the second pressing plate is respectively equipped with above first plane and the second plane, the side of the first pressing plate is connected by screw on the first plane, and the opposite side of the second pressing plate is connected by screw in the second plane.First pressing plate and the second pressing plate are all connected by screw, the height of adjustable first pressing plate and the second pressing plate, thus the blank of clamping different-thickness; The screw of the first pressing plate and the second pressing plate is connected to opposite side, like this when placing blank, can not limit by the length of blank, no matter blank how long, all one end of blank can be snapped in from one of them pressing plate bottom, and then blank is retreated, until the other end of blank is stuck in another pressing plate bottom, by two the spacing blanks of screw be oppositely arranged, thus realize the clamping position of blank.
Further, can insert the voussoir of inverted V-shaped between the first inclined-plane and the second inclined-plane, the both sides end face of voussoir offsets with the first inclined-plane and the second inclined-plane respectively.Voussoir, when punch forming, plays supporting blanks and to be stamped the effect in portion, prevents that stamping press is excessive causes blank fracture etc.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: punch 1, upper bolster 2, blank 3, first pressing plate 4, first die 5, die shoe 6, voussoir 7, second die 8, gathering sill 9, second pressing plate 10.
Embodiment is substantially as shown in Figure 1: the present embodiment adopts the bending die of split type die, upper bolster top is connected with die shank, upper bolster counterdie has mounting groove, the cross section of mounting groove is square, the top of punch is positioned at mounting groove, and connects upper bolster and punch at upper bolster laterally through screw.Punch can move up and down under the drive of power.The lower end of punch has the V-arrangement face of protrusion.
Die shoe is positioned at bottom, and die is positioned at immediately below punch, and die comprises the first die and the second die that are oppositely arranged, and die shoe top has a gathering sill, and the first die and the second die are all positioned at gathering sill, and the first die is fixedly installed.
First die and the second die have the first screwed hole and the second screwed hole, first screwed hole is relative with the second screwed hole position and rotation direction is contrary, a screw rod is connected with at the first screwed hole and the second screwed hole internal thread, first die top has the first inclined-plane, second die top has the second inclined-plane, V-shaped groove is formed between first inclined-plane and the second inclined-plane, can insert the voussoir of inverted V-shaped between the first inclined-plane and the second inclined-plane, the both sides end face of voussoir offsets with the first inclined-plane and the second inclined-plane respectively.
The present embodiment, first die and the second die top also have the first plane and the second plane respectively, the first pressing plate and the second pressing plate is respectively equipped with above first plane and the second plane, the side of the first pressing plate is connected by screw on the first plane, the opposite side of the second pressing plate is connected by screw in the second plane, in the present embodiment, the side of the first pressing plate is bent to form occlusion part downwards, and the opposite side of the second pressing plate is bent to form corresponding occlusion part downwards.
