Description

CUT

Technical field:

The utility model belongs to mechanical field, relates in particular to a kind of CUT that is used for cutting metal material.

Background technology:

CUT is that the plasma arc with HTHP is a thermal source, when the arc column of electric arc and high velocity air during by cutting torch nozzle aperture, make the electrical heat energy of electric arc concentrate (compression) program to improve, to be cut metal local melting and with high velocity air molten metal being blown away simultaneously, and form narrow otch air plasma cutter be to use AC power and compressed air just can cutting stainless steel, steel alloy, carbon steel, aluminium, copper, by the emperor himself, the thermal cutting equipment of nearly all metal such as composition metal.It has low, simple to operate safe in utilization, the advantage such as slot is little, cut surface fineness is good, and the material of cutting is indeformable of cutting cost, is optimal thermal cutting equipment.

CUT is widely used in nearly all industries such as shipbuilding, automobile chemical industry, railway, machinery, household electrical appliances.Owing to be subjected to the influence of wire voltage current loss, the cutting torch nozzle can not surpass three meters from the distance of main frame, and surpassing three meters its cutting effects will weaken greatly, not reach desirable effect but the cleavable site inclement condition, dust has a strong impact on the service behaviour of main frame, and main frame need be away from cleavable site; Sometimes according to the requirement of cleavable site, the cutting torch nozzle needs the remote cutting of moving sometimes, and the cutting torch nozzle is confined in three meters distances of main frame now, has restricted the flexibility of cutting torch nozzle.And most CUT is a hand-held all in the prior art, in use is prone to accidents.

The utility model content:

The purpose of this utility model is to be used for remedying the deficiencies in the prior art, and a kind of CUT is provided

To achieve these goals, the technical solution of the utility model is as follows:

CUT, this cutting machine comprise body, be used to the cutting cutting torch carrying the air compressor machine of cutting gas and be used for metal material is cut, and described air compressor machine is connected by gas pipeline with the cutting cutting torch,

This cutting machine comprises that also stepper motor, reduction box, gear and tooth bar, one are used to install the scalable anchor clamps of cutting cutting torch and the automatic control system of a control step motor movement, described stepper motor and reduction box are in transmission connection and are co-located on the body table top, described gear is connected with reduction box power, described rack and pinion engaged transmission, described tooth bar and scalable anchor clamps join.

Described automatic controlling system connects stepper motor.

Described scalable anchor clamps are inverted L shape, and it is provided with the teeth that are used to regulate its length.

Described tooth bar is fixed on the body table top by two Ω type fixtures.

The utility model CUT, by stepper motor cutting torch is cut in its control, reduce personnel and directly contacted the cutting cutting torch, significantly reduced its potential safety hazard, when cutting metal material, only need it to be carried out the corresponding instruction operation and move the cutting cutting torch by automatic control system, cutting speed is fast, especially when cutting normal carbon steel sheet, speed can reach 5～6 times of the oxygen cutting method, cut surface is bright and clean, thermal deformation is little, almost do not have the heat affected area.

Description of drawings:

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model structural representation

Fig. 2 is a scalable clamp structure schematic diagram in the utility model

The specific embodiment:

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 1: CUT, this cutting machine 100 comprise body 101, be used to the cutting cutting torch 103 carrying the air compressor machine 102 of cutting gas and be used for metal material is cut, and air compressor machine 102 and cutting cutting torch 103 are connected by gas pipeline,

This cutting machine also comprises stepper motor 200, reduction box 201, gear 202 and tooth bar 203, one is used to install the scalable anchor clamps 300 of cutting cutting torch and the automatic control system 2001 of a control step motor 200 motions, stepper motor 200 provides power source for it, first stepper motor spare is controlled in the open loop that electric impulse signal is changed into angular displacement or displacement of the lines, its operation is comparatively stable, and stepper motor 200 is in transmission connection with reduction box 201, increased the transmission performance of stepper motor 200 so greatly, stepper motor 200 is co-located on the table top of body 101 with reduction box 201.

Gear 202 is connected with reduction box 201 power, gear 202 is installed in a side of reduction box 201, by reduction box 201 is its transfer motion power, make its rotation, below gear 202, be mated and be provided with tooth bar 203, tooth bar 203 and gear 202 engaged transmission, tooth bar 203 is fixed on the body table top by two Ω type fixtures, tooth bar 203 under the drive of gear 202, side-to-side movement.

As shown in Figure 2: the end in addition at tooth bar 203 is set with scalable anchor clamps 300, scalable anchor clamps 300 are inverted L shape, in tooth bar 203 motions, drive scalable anchor clamps 300 synchronously, moving back and forth about it is done, scalable anchor clamps 300 are provided with teeth 301, by regulating the position of teeth 301, can regulate the length of scalable anchor clamps 300.

Automatic control system 2001 control connection stepper motors 200 are controlled by the state of automatic control system 2001 stepper motors 200.The position of in the process of using, at first adjusting scalable anchor clamps 300, this depends on cutting cutting torch 103 and is cut distance between the material, adjusted as required, adjust after the position, open air compressor machine 102, cutting cutting torch 103 is started working, make its startup by automatic control system 2001 control step motors 200 then, gear 202 drives tooth bar 203 side-to-side movements after starting, next plays motion to scalable anchor clamps 300 in the drive of tooth bar, and cutting cutting torch 103 begins being cut material cutting thereupon.
