Embodiment Construction

[0015] The present invention will be described in more detail below with examples in conjunction with the accompanying drawings.

[0016] combine Figure 1 to Figure 3 , the CNC machete machine of the present invention uses a machete device as a whole consisting of a work surface 1, a moving knife block mechanism 2 for feed motion, a fixed knife block mechanism 3 with variable angles, and a blade 4 as a work object. The shape of the blade to be bent is determined by the computer to determine the V-shaped angle size of the fixed knife block 15 and the feed rate of the movable knife block 7, and then convert the required rotation angles of the motors 5 and 13. The motor 13 drives the positive and negative lead screw 10 to rotate through the shaft coupling 12. When the lead screw 10 rotates, it drives the two lead screw nuts 9 and 14 to move toward each other, and controls the angle change of the fixed knife block 16 through the connecting rod 15, and 16 and 7 The angle bisector...

Abstract

The invention provides a knife bending device of a numerical control knife bending machine. The knife bending device of the numerical control knife bending machine comprises a movable knife block mechanism and a fixed knife block mechanism. The movable knife block mechanism comprises a first motor, a first lead screw, a first sliding block and a movable knife block, wherein the first motor is connected with the first lead screw; the first sliding block is installed on the first lead screw; and the movable knife block is installed on the first sliding block. The fixed knife block mechanism comprises a second motor, a second lead screw, a second sliding block, a third sliding block and a fixed knife block, wherein the second motor is connected with the second lead screw; the second sliding block and the third sliding block are installed on the second lead screw; and the fixed knife block forms a V-shaped angle by hinging two stress plates, the two stress plates are hinged to one ends of two connecting rods correspondingly, and the other ends of the connecting rods are hinged to the second sliding block and the third sliding block correspondingly. By changing the structure of the knife bending device, the bending force is reduced under the condition of the same bending torque, and a thick blade can be bent by a large angle.

Description

technical field [0001] The invention relates to a machete machine, in particular to a machete device for a numerically controlled machete machine. Background technique [0002] The machete machine is widely used in electronics, printing and packaging, shoe sole production and other industries. Its function is to bend the blade used for die cutting into the required shape. Its working principle is to bend the blade along this point by applying a bending moment to the blade. As described in the technical solution disclosed in the Chinese patent document with application number 201320269485.5, the edge of the curved knife is a fixed knife through which the blade can pass through the center. The machete is composed of a head and a movable cutter head that can rotate around the outlet position of the fixed cutter head, and the movement of the machete is completed by the rotation of the movable cutter head. The distance between the fixed cutter head and the moving cutter head is ...
