Abstract

A bending die of a reverse turning bed structure is mainly formed by installing a workpiece, a support seat, a folding block, a resetting plate, a reverse turning bed positioning block, a stripper plate, and a reverse turning bed which is horizontally placed between the stripper plate and the reverse turning bed positioning block, and the reverse turning bed is in sliding and rotating combination during movement, namely slight sliding exists in the movement taking rotation as the main part, so that the die not only ensures high bending height of a part, and requirements of the appearance, but also avoids scratch on the part during the bending.

Description

A kind of Bending Mould of turnover panel structure

Affiliated technical field

The utility model belongs to the diel field, especially a kind of Bending Mould of turnover panel structure.

Background technology

At present, in the diel, common Bending Mould adopts the folded block structure, and this simple in structure, expense is lower, and is more commonly used, and still, the scratch to part in the bending process is heavier, and the folded block structure has certain limitation to part shape.Higher when the part bending height, when R was big in the bending, product had big resilience, and when product had appearance requirement again, the Bending Mould of folded block structure was just inapplicable.

Summary of the invention

The purpose of this utility model is exactly to have the technical deficiency of Bending Mould now in order to solve, and a kind of Bending Mould of turnover panel structure is provided, thereby has guaranteed the requirement of part bending height height and outward appearance aspect.

The technical scheme that its technical problem that solves the utility model adopts is: the Bending Mould of turnover panel structure, by workpiece, supporting seat, folded block, restoring board, turnover panel locating piece and stripper plate, and level places the turnover panel between stripper plate and the turnover panel locating piece that composition is installed, when mould during in the bending original state, the turnover panel level places between stripper plate and the turnover panel locating piece; When folded block slided to the operating position, stripper plate began descending, and workpiece drives turnover panel and rotates around the wedge angle point of supporting seat, and turnover panel can be done to slide relatively at the supporting seat sharp corner; When turnover panel forwards between upright insertion stripper plate and the supporting seat around run-on point, this moment, stripper plate continued downwards, then turnover panel moves downward under the stiction of material drives, and turnover panel and supporting seat slide, and is shaped when turnover panel descends to 6～8mm below supporting seat and finishes; During the demoulding, stripper plate is by jack-up, and turnover panel is upwards released under the effect of restoring board, deviates from end blocking fully and outwards stirs with workpiece around the strong point of supporting seat under the effect of self gravitation and break away from, after the overturning under the big fillet effect of turnover panel locating piece from centering, be returned to reset condition.

The beneficial effects of the utility model are, the Bending Mould of turnover panel structure, turnover panel slides at the volley and combines with rotation, have a small amount of slip in the motion based on rotation, make mould not only guarantee the requirement of the high and outward appearance aspect of part bending height, and avoided in the bending process scratch part.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is present Bending Mould structural representation.

Fig. 2, Fig. 3, Fig. 4 are the Bending Mould bending view of turnover panel structure.

1. turnover panels among the figure, 2. workpiece, 3. turnover panel locating piece, 4. supporting seat, 5. folded block, 6. stripper plate, 7. restoring board.

The specific embodiment

Mould is when the bending original state, and turnover panel (1) level places between stripper plate (6) and the turnover panel locating piece (3).

In Fig. 2, when folded block (5) slided to the operating position, stripper plate (6) beginning was descending, and workpiece (2) drives turnover panel (1) and rotates around the wedge angle point of supporting seat (4), and turnover panel (1) can be done to slide relatively at supporting seat (4) sharp corner.

In Fig. 3 embodiment, when turnover panel (1) forwards between upright insertion stripper plate (6) and the supporting seat (4) around run-on point, stripper plate this moment (6) continues downwards, then turnover panel (1) moves downward under the stiction of material drives, turnover panel (1) slides with supporting seat (4), is shaped when turnover panel (1) descends to 6～8mm below supporting seat (4) and finishes;

In Fig. 4 embodiment, during the demoulding, stripper plate (6) is by jack-up, turnover panel (1) is upwards released under the effect of restoring board (7), deviating from end blocking (1) strong point around supporting seat (4) under the effect of self gravitation fully outwards stirs and workpiece (2) disengaging, after the overturning under the big fillet effect of turnover panel locating piece (3) from centering, be returned to reset condition.

Claims

1. the Bending Mould of a turnover panel structure, form by turnover panel, workpiece, supporting seat, folded block, restoring board, turnover panel locating piece and stripper plate installation, it is characterized in that: mould is when the bending original state, and turnover panel is that level places between stripper plate and the turnover panel locating piece.

2. the Bending Mould of turnover panel structure according to claim 1 is characterized in that: when folded block slided to the operating position, stripper plate began descending, and workpiece drives turnover panel and rotates around the wedge angle point of supporting seat, and turnover panel can be done to slide relatively at the supporting seat sharp corner.

3. the Bending Mould of turnover panel structure according to claim 1, it is characterized in that: when turnover panel forwards between upright insertion stripper plate and the supporting seat around run-on point, this moment, stripper plate continued downwards, then turnover panel moves downward under the stiction of material drives, turnover panel and supporting seat slide, and are shaped when turnover panel descends to 6～8mm below supporting seat and finish.

4. the Bending Mould of turnover panel structure according to claim 1, it is characterized in that: during the demoulding, stripper plate is by jack-up, turnover panel is upwards released under the effect of restoring board, deviating from end blocking fully outwards stirs with workpiece around the strong point of supporting seat under the effect of self gravitation and breaks away from, after the overturning under the big fillet effect of turnover panel locating piece from centering, be returned to reset condition.
