Convex-concave die device capable of preventing material clamping

Abstract

The invention discloses a convex-concave die device capable of preventing material clamping, and relates to the technical field of machining. The convex-concave die device comprises a concave die anda convex die, wherein a blanking hole is formed in the upper surface of the concave die, the convex die is in sliding fit with the blanking hole, sliding grooves are formed in the side faces of the periphery of the concave die, the sliding grooves communicate with the blanking hole, and sliding blocks are connected in the sliding grooves in a sliding mode. According to the convex-concave die device, a brush roller, the sliding blocks, a push block, a second spring and a screw rod are used, so that material clamping is avoided; and the screw rod can be driven to rotate by rotating a knob, the screw rod can drive the push block to move forwards or backwards, the closer the push block is to the blanking hole, the larger the pressure borne by the brush roller is, the larger the friction forceis, otherwise, the smaller the friction force is, so that the adjusting effect is achieved. According to the convex-concave die device, a fixed frame, a movable frame, a sliding rod and a first springare used, when the convex die is used for blanking a workpiece, a sliding frame can be extruded to slide upwards, when the convex die is reset, the sliding frame can be reset along with the convex die, in the process, the sliding frame can further remove waste on the surface of the convex die, and material clamping is further prevented.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular to a convex and concave mold device for preventing material jamming. Background technique [0002] The punch-and-concave die structure is generally used in the compound die, and the compound die refers to a die structure in which the punching machine completes multiple processes such as blanking and punching in one stroke. Compared with other cold stamping die structures, it has the following advantages: better coaxiality of the workpiece, straight surface, and higher dimensional accuracy; high production efficiency, and is not limited by the accuracy of the shape of the strip, and sometimes waste corners Can also be used for reproduction. The compound mold structure is welcomed by customers because of its high production efficiency and good dimensional accuracy of the workpiece; but at the same time, the usual processing methods are not satisfactory due to the limita...
