Description

Differential or integral electric scissors [ Technical field ] The present invention belongs to the field of mechanical technology. Specifically, the integrated action of the cumulative punching of the micro-punching head is combined with the central rotation constraint of the circumferential constraint to generate the hand-held electric scissors capable of flexibly controlling the cutting direction in a mode of cumulative cutting of the micro-punching head. [ Background Art ] The traditional electric shearing equipment mostly adopts the principle of scissors, and a motor of the traditional electric shearing equipment rotates through a controller, so that the original speed is maintained or the motor is decelerated through a speed reducer and is output in the direction of a motor shaft instead of the direction perpendicular to the output direction of the motor shaft, or the relative movement of double blades of the scissors is realized under the drive of a gear, and therefore the shearing function can be realized. The electric shears are divided into a common single blade group (2-blade shears: electric shears such as branches) or a multi-blade group (consistent with multi-blade shears: electric clippers such as shaving heads), and the principle is that the lever principle is used. [ Summary of the invention ] The invention aims to overcome the defects of difficult turning operation, easy material deformation and curling, difficult processing of thicker materials and the like of the traditional double-blade moving electric scissors, and designs the electric scissors which work in a mode of micro-stamping accumulation cutting, are easy to turn operation, smooth and curling-free in materials and adapt to thicker materials. The electric scissors are easy to hold, stable in cutting and flexible in steering, and are more beneficial to cutting complex patterns and various materials. The differential or integral electric scissors structurally comprise a differential or integral round-segment punch, a round-segment connecting part, a differential or integral lower die disc and an electric driving assembly, wherein the electric driving assembly is an assembly which is driven by a motor to drive a sliding rod by a connecting rod or directly drive a sliding rod horizontal bar hole to drive the sliding rod to reciprocate, or an assembly which is driven by a motor to drive a sloping cam to rotate to axially push the sliding rod to reciprocate (the rebound of the sliding rod can depend on a spring), or an assembly which is driven by the reciprocation of a linear motor or an electromagnet to drive the sliding rod to reciprocate, and finally drives the differential or integral round-segment punch fixed on the sliding rod to do linear reciprocation, and to reciprocate through a punching hole of the differential or integral lower die disc and to do punching or extrusion under the matching of the differential or integral lower die disc; thus, in satisfying the free travel and flexible rotation of the sheet to be cut in the cutting slit, the cross section of the complex of the round-missing punch and the round-missing connecting portion must satisfy the following conditions: Defining the punch width W1, the connecting part width W2, the overall length L1, the connecting part length L2, the brown length X of the punch end and the thickness H of the punch top, under the constraint of the geometrical relationship, the following conclusion is drawn: * The flexible feed criterion (filling condition) is that the width W1 of the punch is more than or equal to the width W2 of the connecting part, Namely W1 is more than or equal to W2; * The flexible rotation criterion (the requirement) is that the width W1 of the punch is more than or equal to the total length L1 or the width W1 of the punch is more than or equal to the total length L2, Namely W1 is larger than or equal to L1 or W1 is larger than or equal to L2 (under the condition of lifting the punch); therefore, in summary, the round punch and the round connecting part need to be mutually close together, and the contour line of the round punch and the round connecting part is a uniform circumference or 2 combined circumferences with approximate radii or a curved edge or straight edge polygon; * The condition of cutting edge and leveling edge (not necessary) is that the brown length X of the end part of the punch is more than or equal to the thickness H of the top part of the punch; X is more than or equal to H; The contour of the combined part of the differential or integral round-cut punch and the round-cut connecting part with the cutting-in round-cut structure is in a whole circumference shape (except for the cutting-in round-cut part), or the curvature radius of the round-cut punch is larger than that of the cutting-in round-cut structure, which is equivalent to the insertion function of machining a cutting-in round-cut on the round-cut connecting part; The shearing line of the
