Abstract

The utility model provides a cut-off machine. The cut-off machine comprises servo motors, an upper cutter and a lower cutter which are used for cutting off material on a production line, the rotating tangential speed of the upper cutter and the lower cutter is identical to the conveying speed of the material on the production line, the number of the servo motors is two, and the two servo motors respectively drive the upper cutter and the lower cutter to cut off the material on the production line. According to the cut-off machine, the double servo motors are used for respectively driving the upper cutter and the lower cutter, the upper cutter and the lower cutter operate independently of each other to adapt to the requirement of the high speed production line, and the cutters start up relatively fast, and are not prone to damaging the motors when the cut-off machine is shut down.

Description

A kind of cutting machine

Technical field

The utility model relates to a kind of shearing device, particularly, relates to a kind of cutting machine.

Background technology

In the prior art, the mode of cutting off the material on the production line mainly contains two kinds: a kind of is to cut off material by the single cutting knife of motor-driven, because the problems such as cutting knife rotating speed, cutting knife often can interfere with material transmitting device on the production line, cause the blank tangent plane damaged, make some blanks not reach product standard; Another mode is to cut off material by the two cutting knifes of single motor-driven; as shown in Figure 1; material cuts off by upper cutter 1 and lower cutter 2 in the process of transporting on the production line; upper cutter 1 and motor of lower cutter 2 usefulness drive; the direction of rotation of upper cutter 1 and lower cutter 2 tangential velocity opposite and rotation is identical; the tangential velocity of upper cutter 1 and lower cutter 2 rotations is identical with the speed that the material 3 on the production line transports; and the carriage direction of the material 3 during upper cutter 1 blank on direction of action and the production line is identical; this mode is owing to used two cutting knifes to cut material; tangent plane is more smooth; but this mode is not suitable for high-speed production lines; it is fast that high-speed production lines is transported the speed of material; and the tangential velocity of cutting knife is identical with the travelling speed of the material of production line; so need the High Rotation Speed of two cutting knifes; if use the two cutting knifes of single driven by motor; can increase the weight of the load of motor; damage easily motor; and two cutting knifes moment of torsion in High Rotation Speed is larger; when shutting down, easily motor is caused damage; and when the start operation; the time that two cutting knifes start is longer, has reduced production efficiency.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model discloses a kind of cutting machine, use Dual-Servo Motor to drive respectively lower cutter, avoided shutting down the slower problem of startup when causing motor damage and start.

The cutting machine that the utility model provides comprises: servomotor and the upper cutter and the lower cutter that are used for cutting off the material on the production line, the tangential velocity of described upper cutter and lower cutter rotation is identical with the speed that the material on the described production line transports, described servomotor is two, drives respectively described upper cutter and lower cutter and cuts off simultaneously material on the production line.

Preferably, described cutting machine also comprises controller, and described controller is used for controlling described upper cutter and lower cutter action by described two servomotors.

Preferably, described cutting machine also comprises detecting element, described detecting element is used for measuring the speed that material transports on the production line, and the speed that described material transports sent to described controller, the speed that the material that described controller sends according to described detecting element transports is moved by described two described upper cutters of driven by servomotor and lower cutter.

The utility model uses Dual-Servo Motor to drive respectively lower cutter, and the operation independent of one another of upper lower cutter adapts to the needs of high-speed production lines, and cutting knife starts very fast, and also is not easy motor is caused damage when shutting down.

The specific embodiment

Core concept of the present utility model is: the shortcoming for the single cutting knife of motor-driven of the prior art and the two cutting knifes of single motor-driven has designed a kind of cut-out technology; use Dual-Servo Motor to drive two cutting knifes; each servomotor all drives a cutting knife; each cutting knife is single movement under the driving of its drive motors, starts slowly when having avoided the two cutting knife of single motor-driven, shuts down easily to motor and the hurtful problem of equipment.

Among the embodiment provided by the utility model, a kind of cutting machine is provided, as shown in Figure 2, comprise: servomotor and the upper cutter and the lower cutter that are used for cutting off the material on the production line, the tangential velocity of upper cutter and lower cutter rotation is identical with the speed that the material on the production line transports, servomotor is two, drives respectively upper cutter and lower cutter and cuts off simultaneously material on the production line

In order to realize to the accurate control of upper cutter and lower cutter action controller being set, by two servomotor control upper cutters and lower cutter action.

In two cutting-off tool systems, the direction of rotation of upper lower cutter tangential velocity opposite and rotation is identical, and the tangential velocity of upper cutter and lower cutter rotation is identical with the material speed of transporting on the production line, therefore, detecting element can be set measure the travelling speed of material on the production line, then realize accurate control to two cutting knife rotary speeies by controller, the travelling speed of material is identical on the tangential velocity that makes two cutting knifes rotations and the production line.

As shown in Figure 3, operating procedure of the present utility model is as follows:

Upper cutter, lower cutter and two servomotors are set,

The tangential velocity of upper cutter and lower cutter rotation is identical with the speed that the material on the production line transports;

Two servomotors drive respectively described upper cutter and lower cutter and cut off simultaneously material on the production line.

It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
