Abstract

The utility model discloses a pair of fixed size scissors, which comprises a plate shearing machine, a first conveying roller way formed at the material inlet end of the plate shearing machine and a second conveying roller way formed at the material outlet end of the plate shearing machine, wherein the first conveying roller way directly conveys a steel plate into the plate shearing machine; a laser size fixing device is arranged on the plate shearing machine, and comprises a controller and a displacement sensor; the displacement sensor is used for detecting a head position signal of the steel plate and inputting a detected signal into the controller; and the controller is used for analyzing and processing the signal input by the displacement sensor and sending a control signal to a driving motor of the first conveying roller way. According to the fixed size scissors, a pinch roller device of the conventional fixed size scissors is not used, so that the influence of the fault of a pinch roller on the fixed size scissors is eliminated; furthermore, a feeding amount of the steel plate is determined by the laser size fixing device, so that manmade errors are eliminated, and the size of the steel plate is relatively precise; and moreover, automatic operation is realized, the work efficiency of the fixed size scissors is improved greatly, and the working intensity of an operator is reduced.

Description

Scale is cut

Technical field

The utility model relates to a kind of steel plate and cuts off equipment, particularly a kind of cutting to length machine.

Background technology

Scale of the prior art is cut, and it comprises: what a rollgang, was used for accurately sending plate pinches a rod device and a plate shearing machine; When work; Earlier steel plate head is delivered to the plate shearing machine clip through pinching the rod device; On steel plate, draw the position line of definite clipped position down according to the steel plate length specification again, restart and stop to send plate after pinch roll apparatus is delivered to position line and clip alignment with steel plate, cutter is sheared.

This manual work sees that the shearing of chi, the scale that pinch roll send plate cut, and when work, has following defective:

1, manual work sees that the chi error is bigger, makes the operator tired easily, and labour intensity is bigger, and shear efficiency is lower.

2, adopt pinch roll apparatus to send plate, pinch roll apparatus can stop operator's sight line, has increased the align difficulty of clip with position line, and pinch roll apparatus can break down simultaneously, causes to produce and pauses, and influences output.

Therefore need cut scale of the prior art and improve, to improve shear precision, to reduce operator's labour intensity and enhance productivity.

The utility model content

In view of this, the purpose of the utility model provides a kind of scale and cuts, and it no longer adopts the people location of ruling confirm the shear position, raising shear precision that can be very big, reduces operator's labour intensity and enhances productivity.

The utility model scale is cut, and comprises plate shearing machine, is arranged on first rollgang of plate shearing machine feed end and is arranged on second rollgang of plate shearing machine discharge end, and said first rollgang is directly sent steel plate into plate shearing machine;

Said plate shearing machine is provided with the laser length measuring device, and said laser length measuring device comprises controller and displacement transducer;

Displacement transducer is used to detect the steel plate head position signalling, and detection signal is imported controller;

Controller is used for the signal of analyzing and processing displacement transducer input, and sends control signal to the drive motors of first rollgang, to control the transporting velocity of first rollgang.

Further, said displacement transducer is a laser displacement sensor.

The beneficial effect of the utility model: the utility model scale is cut, and has cancelled the pinch roll apparatus that traditional scale is cut, and has eliminated the pinch roll fault is cut production to scale influence; And this scale is cut and is adopted the laser length measuring device to confirm the steel plate amount of feeding, has eliminated to think and error make plate size more accurate, and has realized automated job, improves the operating efficiency that scale is cut greatly, has reduced operator's working strength.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the utility model scale shear structure sketch map;

Fig. 2 is the enlarged diagram of P portion among Fig. 1.

The specific embodiment

Fig. 1 is the utility model scale shear structure sketch map; Fig. 2 is the enlarged diagram of P portion among Fig. 1.

As shown in the figure, the present embodiment scale is cut, and comprises plate shearing machine 1, is arranged on first rollgang 2 of plate shearing machine feed end and is arranged on second rollgang 3 of plate shearing machine discharge end, and said first rollgang 2 is directly sent steel plate into plate shearing machine 1;

Said plate shearing machine 1 is provided with laser length measuring device 4, and said laser length measuring device comprises controller and displacement transducer;

The utility model scale is cut, and has cancelled the pinch roll apparatus that traditional scale is cut, and has eliminated the pinch roll fault is cut production to scale influence; And this scale is cut and is adopted the laser length measuring device to confirm the steel plate amount of feeding, has eliminated to think and error make plate size more accurate, and has realized automated job, improves the operating efficiency that scale is cut greatly, has reduced operator's working strength.

In this enforcement; Said displacement transducer is a laser displacement sensor; It can accurately measure the positional information and the change in location information of steel plate head under the noncontact situation; Controller send plate speed according to what thereby the detection information of laser displacement sensor was accurately controlled first rollgang, and the amount of feeding is accurate, and the plate size precision is high.

Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the aim and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.

Claims
