Description of the embodiments

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the utility model provides a die overturning and positioning mechanism, which comprises a material pressing core 1 and a die male die 2 arranged below the material pressing core 1, wherein an inward inclined angle 201 is formed on the die male die 2, a driving pressing plate 3 is arranged on the material pressing core 1, an overturning and positioning assembly 4 is arranged on the die male die 2 below the driving pressing plate 3, the overturning and positioning assembly 4 comprises a positioning shaft 401, a positioning plate 402, a connecting rod 403 and a spring 404, the positioning shaft 401 is horizontally arranged on the die male die 2, the positioning plate 402 is rotatably arranged on the positioning shaft 401, an outwards extending connecting rod 403 is arranged below the positioning plate 402, a spring 404 is arranged below the connecting rod 403, and the driving pressing plate 3 can downwards contact the connecting rod 403.

By setting the length of the connecting rod 403, the front end of the connecting rod 403 moves from the bottom of the driving pressing plate 3 to the side surface of the driving pressing plate 3 after the driving pressing plate 3 moves downwards for a certain distance, at this time, the workpiece is reversely pushed to a specified position, the side surface of the driving pressing plate 3 is tangent to the front end of the connecting rod 403, the connecting rod 403 does not follow the driving pressing plate 3 any more, the pressing core 1 can continue to be pressed downwards, and no pressure is applied to the overturning and positioning assembly 4 any more. The front end of the connecting rod 403 is in an arc structure, so that the friction force contacted with the side surface of the driving pressing plate 3 is reduced. The bottom of the spring 404 is fixed on the die male die 2 to prevent falling off. The driving pressing plate 3 and the overturning and positioning assembly 4 are symmetrically arranged in two pairs, and the thrust output of the opposite workpiece is more stable.

According to the utility model, the driving pressing plate 3 arranged on the pressing core 1 is matched with the overturning and positioning assembly 4 arranged on the die male die 2, when a workpiece is placed on the die male die 2, the pressing core 1 descends, the driving pressing plate 3 downwards abuts against the connecting rod 403 in the overturning and positioning assembly 4, and the workpiece is reversely pushed by mechanical action, so that the negative angle profile of the workpiece is attached to the inclined angle 201 on the male die, thereby reducing the manual participation amount and reducing the abnormal risk of being placed in place.

The working principle is as follows:

firstly, a workpiece is placed on a die male die 2, at the moment, the front end of a connecting rod 403 is located at a point a of fig. 5, then a pressing core 1 is driven to move downwards, when a driving pressing plate 3 on the pressing core 1 is abutted to the connecting rod 403, the connecting rod 403 starts to move downwards under pressure, a positioning plate 402 is driven to rotate around a positioning shaft 401, the top of the positioning plate 402 acts to push the workpiece leftwards, the front end of the connecting rod 403 gradually reaches a point b from the point a to the point c along with the continuous descending of the pressing core 1, the workpiece is reversely pushed to a designated position by the top of the positioning plate 402 at the moment, the negative angle profile of the workpiece is attached to an inclined angle 201 on the male die, the side surface of the driving pressing plate 3 is tangent to the front end of the connecting rod 403, the connecting rod 403 does not act along with the driving pressing plate 3, the pressing core 1 can continue to press downwards, and pressure can not be applied to a turnover positioning assembly 4. When the processing of the workpiece is completed, the pressing core 1 is lifted, and the overturning and positioning assembly 4 is restored to the original position under the action of the spring 404.
