Description
Technical Field
The utility model belongs to hole flanging mould field, concretely relates to material returned mechanism in special-shaped hole turns over.
Background
The hole flanging refers to a stamping method for flanging the hole edge of a plate into a vertical edge by using a die, and is mainly used for manufacturing an assembly part of a related part or processing a specific shape for improving the rigidity of the part. After hole flanging, the side wall of the hole is attached to the side wall of the female die, so that the situation that a workpiece is clamped in the female die and cannot be taken out easily occurs during hole flanging. The special-shaped hole flanging is easy to generate the condition, and the special-shaped hole flanging material returning mode in the prior art mainly comprises two modes: standard flange lifters or cylinder multi-point ejection are used. Both methods have extremely high space requirements and cannot be realized for a large part of parts.
The existing chinese patent document CN201721332161.6 discloses a side hole-turning mechanism in a stamping die, which has the main technical scheme that: the side hole-turning mechanism comprises a driving block, a sliding block, a side material pressing plate, a hole-turning punch and a hole-turning female die, and the improvement is as follows: the hole flanging female die is divided into a sliding part and a fixed part in the horizontal direction, one side with an extrusion working surface is the sliding part, the other side is the fixed part, the fixed part is arranged on the female die seat, the interface of the sliding part and the fixed part inclines from bottom to top towards the direction deviating from the sliding part, the sliding part and the fixed part are in sliding fit with the cross sliding groove profile at the interface, and the lower end of the sliding part of the female die is provided with a nitrogen spring for pushing the sliding part upwards. Different from the scheme of the utility model.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem and providing a returning charge mechanism in special-shaped hole that turns over that stable in structure, save space, hole flanging precision are high.
In order to achieve the above object, the utility model provides a following technical scheme:
a material returning mechanism for turning a special-shaped hole comprises a material pressing core and a hole turning male die arranged in the material pressing core, wherein a top rod is connected below the hole turning male die, a material returning block is arranged below the top rod, and the top rod and the material returning block move along with the movement of the hole turning male die; the material pressing core is provided with a hole flanging female die below, the material returning block is fixed on the hole flanging female die through a limiting part, an elastic part is arranged between the material returning block and the hole flanging female die, and the limiting part is used for fixing and controlling the position of the material returning block.
Preferably, the limiting member is a limiting screw.
Preferably, the elastic member is a spring.
The beneficial effects of the utility model reside in that:
the utility model fixes the ejector rod on the hole flanging male die, presses the material returning block down before the hole flanging male die touches the material, starts hole flanging and finishes hole flanging; the hole flanging male die rises, and the material returning block ejects a product at the hole flanging position under the action of the spring. The utility model provides a problem that the work piece card can't take out in the die, overall structure is simple and easy stable, very big space that has reduced hole flanging feed back device is applicable to various opposite sex hole flanging structures. The purpose of returning the materials of the special-shaped hole flanging is realized, and the precision of the product at the hole flanging position is improved.
