Dual-servo-motor angle shear machine

Abstract

The invention discloses a dual-servo-motor angle shear machine and belongs to the field of feeding machines of glass bottle machinery. The dual-motor servo angle shear machine is characterized in that a support frame comprises a support bracket (1) and a motor bracket (3); a shear device comprises two servo motors (4), a left connecting rod mechanism, a right connecting rod mechanism, shear arm support devices, a left shear arm (6) and a right shear arm (7); the two servo motors (4) are mounted on the motor bracket (3); the output ends of the servo motors (4) vertically and downwardly extend out of the lower plane of the motor bracket (3) and are connected with two cranks (5) respectively; the two cranks (5) are connected with the left connecting rod mechanism and the right connecting rod mechanism respectively; the other end of each of the left connecting rod mechanism and the right connecting rod mechanism is connected with each shear arm support device; the shear arm support devices are connected with the left and right shear arms (6, 7) which can be occluded with each other. According to the dual-servo-motor angle shear machine, the shearing operation is stable, the reversing motion cannot be made, the shearing quality is good, and the shearing position can be adjusted.

Description

technical field [0001] The utility model relates to a double-motor servo angle shear, which belongs to the field of feeding machines of glass bottle making machinery, and in particular relates to an angle shear used for the feeding machine. Background technique [0002] The feeding machine is one of the common equipment in the field of glass bottle making machinery. With the development of glass bottle making machines, the demand for high-efficiency and high-quality feeding machines in the current international and domestic markets continues to increase, and the angle shears are the most important parts of the feeding machine. The main components of the feeder, whether its work is stable, and whether its functions are complete are directly related to the quality of the feeder. At present, the angle shears used by most feeders in China rely on the scissors cam on the gear box of the feeder to complete the work. The cam roller and the scissors pull rod open the scissors under ...

AI Technical Summary

Problems solved by technology

When the angle shear machine is cutting, the scissor arm needs to change direction, which has a large recoil force, the cutting speed is slow, and the movement is not stable. Moreover, at the moment of cutting, the movement track of the scissor arm is not perpendicular to the central axis, and the action repeatability is poor. As a result, the shearing consistency is low, the frequency is low, the shearing is flawed, and it has the disadvantages of incomplete cooling of the scissors and low service life, which seriously restricts the development of the feeder.

At the same time, the existing angle shears are relatively simple in design, and most of them do not have fixing devices. Because they are not fixed during cutting, the work is not stable, and there will be errors in cutting. It is inconvenient to adjust the cutting station
