Technical Field
The utility model belongs to the technical field of stamping and trimming dies, and particularly relates to a trimming knife block of a stamping die and the stamping die.
Background
In the production process of the automobile stamping part, a scrap cutter and certain special modeling parts in the trimming process generate heat, expand and extrude due to the cutter edge, and generate some tiny scrap irons which are often brought into the air due to suction force on air flow when a machine tool slide block ascends or an end effector picks up a part, so that the scrap irons fall into the molded surface of a die, and the defects of crushing, pit wrapping, galling and the like of a stamping part product are caused; especially, for the outer plate, if not found in time, a lot of reworking and scrapping can be caused.
In view of the above problems, there are two common methods for solving the problem:
firstly, installing a blowing device on a mould: an air blowing pipe is additionally arranged at the position of the lower die where the scrap iron falls, and the air blowing rhythm and force are controlled through a machine tool air path system; the disadvantages and shortcomings of this approach include: firstly, the installation position and the air blowing angle of the air blowing device have certain limitations and are not suitable for all trimming working parts, and secondly, the scrap iron blown into the air is not beneficial to the stamping production environment, so that secondary pollution is easy to cause and other equipment such as a machine tool and the like is damaged;
secondly, brushing butter with higher viscosity on the scrap iron falling part of the die, so that the scrap iron is adsorbed by the butter after falling; the disadvantages and shortcomings of this approach include: the problem of scrap iron falling cannot be completely solved by brushing butter, and brushing butter on a knife edge only temporarily solves the problem, addresses the symptoms and does not address the root causes, and influences the appearance of a die and cleaning work; moreover, the grease is easy to be stained on the surface of the workpiece, and the post-process treatment is troublesome.
