Description
Technical field
The utility model belongs to automobile die and makes the field, is specifically related to a kind of last turning mechanism that is used for big kart stamping die.
Background technology
In the auto parts and components, often there is product the situation of upper overturning and following flange to occur, in mould is made, for the part that turns over downwards, in general be relatively good manufacturing, only need a flanging die to fix, patrix is done the flange die plate insert can realize it, and for retrousse part, common way is that the flange die plate insert is fixed on the counterdie, adds movable following holding pad and is used.It is a lot of to occur in the mold operation content like this, and when the trimming and piercing die content was arranged, the precision that trimming and piercing die usually can occur was inaccurate, is difficult to reach the requirement of product, and As time goes on, difficulty can be increasing during to regular maintenance and maintenance.For with the high mould enterprise of quality requirement, its cost is self-evident.
Therefore design a kind of common turning mechanism of going up that is used for substituting, with the workmanship that improves enterprise's mould and the difficulty of regular maintenance, and the image product that promotes enterprise becomes the technical barrier that those skilled in the art press for solution.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, processing is simple, turning mechanism on quality quality height, low cost of manufacture, the depression bar easy to maintenance, to overcome the existing common above-mentioned defective that turning mechanism exists that goes up.
The technical scheme of the utility model technical solution problem is as follows:
Turning mechanism on a kind of depression bar is characterized in that, comprises flange depression bar, back-up block, limited block, presses down cushion block and flanging die;
Described flange depression bar and back-up block are rotationally connected by rotating shaft, and described back-up block is fixed on down on the mould body;
Described flange depression bar two ends are positioned on the upper surface of rotating shaft both sides and are respectively equipped with spill spin block and flange insert seat, and the upper surface of described spill spin block is an arc-shaped surface, and the described cushion block that presses down is fixed on the mould body, and it matches with the upper surface of spill spin block;
Be fixed with flange insert on the described flange insert seat, described flange insert cooperates with flanging die, and described flanging die is fixed on the mould body, the center of described rotating shaft be not less than flange insert peak;
Described limited block is fixed in down on the mould body, corresponding to the bottom of the flange depression bar of spill spin block one side.
Operation principle of the present utility model: the utility model is by adopting lever principle, utilization is by being arranged on flange depression bar rotating shaft both sides with spill spin block and flange insert, make its formation can be by rotating shaft rotating lever structure, during work, pressing down cushion block can move downward along spill spin block, because the curved surface of spill spin block, beginning to drive the flange depression bar is rotated down, because lever principle, the flange insert of another side can be moved from bottom to top, realizes flange.This moment, work arrived bottom dead centre, and flange depression bar bottom contacts with limited block, stoped the flange depression bar to continue motion.After flange finished, patrix left, and pressed down cushion block and moved upward, and broke away from spill spin block along curved surface, and reason or other external force owing to gravity make under the flange insert side direction and moves, and get back to original state, and part both can take out smoothly.
By above disclosed technical scheme as can be known, turning mechanism only needs that when regular maintenance, maintenance and maintenance spill spin block and flange insert are carried out corresponding maintenance, repair and gets final product on the utility model depression bar, adopt on the depression bar turning mechanism not only can reduce in addition to make and reduce unnecessary operation, and the processing and the manufacturing of turning mechanism can be made by automobile die Standard Component Factory on the depression bar, and interchangeability is improved.On the utility model depression bar turning mechanism can be used for big small-sized automobile panel on turn over, the operation content of mould is can be more compact, cost is lower.When product flange length is big, can use two groups and above mechanism to unite use.
Description of drawings
Fig. 1 be on the utility model depression bar turning mechanism at the installation diagram of bottom dead centre;
Fig. 2 be on the utility model depression bar turning mechanism at the front view of bottom dead centre;
Fig. 3 be on the utility model depression bar turning mechanism at the front view of top dead-centre.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Shown in Fig. 1～3, turning mechanism on the utility model depression bar comprises flange depression bar 1, back-up block 2, limited block 3, presses down cushion block 4 and flanging die 5; Described flange depression bar 1 is rotationally connected by rotating shaft 8 with back-up block 2, and described back-up block 2 is fixed on down on the mould body; Described flange depression bar 1 two ends are positioned on the upper surface of rotating shaft both sides and are respectively equipped with spill spin block 11 and flange insert seat 12, the upper surface of described spill spin block 11 is an arc-shaped surface, the described cushion block 4 that presses down is fixed on the mould body, matches in its upper surface with spill spin block 2; Be fixed with flange insert 13 on the described flange insert seat 12, described flange insert 13 cooperates with flanging die 5, and described flanging die 5 is fixed on the mould body, the center of described rotating shaft 8 be not less than flange insert peak; The position in the center of circle by making rotating shaft is higher or contour than the position of the peak of flange insert, does not rotatablely move the situation that flange insert 13 and flanging die 5 are interfered thereby can not appear at.Described limited block 3 is fixed in down on the mould body, corresponding to the bottom of the flange depression bar of spill spin block one side.
Further, can make the center of gravity of the whole flange depression bar 1 that comprises flange insert seat 12, flange insert 13 and spill spin block 11 be positioned at a side at flange insert 13 places, thereby can after flange finishes, utilize gravity, the flange depression bar of flange insert side is descended, make things convenient for taking out of workpiece.Also can utilize external force to make the decline of flange insert side, reach this effect by adding flexible member.
In addition; after guaranteeing the flange end-of-job; anti-locking mechanism can not normally be got back to original state; can increase and force backhaul piece 6; to force backhaul piece 6 to be fixed on the mould body, described pressure backhaul piece 6 is arranged on spill spin block 11 1 sides, and the lower end of described pressure backhaul piece 6 is provided with barb 61; the side of corresponding spill spin block is provided with projection 111, and described barb 61 is positioned at projection 111 belows and cooperates with projection 111.Under the normal condition, force the backhaul piece inoperative, have only when original state can not be got back to owing to external reason by mechanism, force the backhaul piece can haul spill spin block and move upward, guarantee that the punching press of a part finishes.
Because present part punching frequency is all than comparatively fast, particularly automated production.Therefore, buffer 7 can be set below flange insert seat 12, reduce the impulse force that produces owing to inertia, and play the effect of noise reduction.
Described back-up block position 2 for be arranged on flange depression bar 1 two sides be parallel to each other two gripper shoes, the lower end of described two gripper shoes interconnects by lip block 21, described cradle 21 is fixedlyed connected with following mould body.
