Abstract
The utility model relates to an industrial cutting device, in particular to a cutting torch protecting mechanism of a numerical-controlled plasma cutter used for cutting medium-thin metal plate, which aims to be simple in structure and reliable in use. The plasma cutting torch protecting device is provided with a base, a protection cover is arranged above the base, the protection cover includes an upper spring pressing plate and a lower spring pressing plate in vertical arrangement, a pressure spring is arranged between the upper spring pressing plate and the lower spring pressing plate, the lower spring pressing plate contacts with the base, and the upper spring pressing plate is connected with the base via a steel rope. The plasma cutting torch protecting device has the advantages that a plasma cutting torch is mounted in the protection cover, when other objects firstly collide with the protection cover when colliding with the cutting torch so as to prevent the cutting torch from being damaged, and the protection cover is easy in resetting after collision by adopting elastic design.
Description
Technical field
The utility model relates to a kind of industrial cutting equipment, particularly a kind of be used for cutting in the cutting torch protection mechanism of numerical control plasma cutting machine of metal sheet.
Background technology
In the industrial circle, welding structural element all has utilization widely in all trades and professions.The sheet material cutting is the first step in the welding processing process, is the important procedure that guarantees welding quality, and the utilization rate of material is risen several percentage points, and its economic results in society are considerable.Intelligent accurate cutting technique not only can guarantee the welding quality of product, raises labour productivity, simultaneously also make the manufacturing cost of enterprise product descend significantly, shorten life cycle of the product, especially utilize plasma to carry out the groove cutting, from economic angle, it is more and more important to become.Meticulous plasma cutting machines cutting accuracy of numerical control and surface roughness can reach the lower range of laser cutting, invest little, maintaining, operating cost is low, is the first-selected economic cutting equipment that substitutes laser cutting.In steel construction was produced, this product shared ratio in market sale was ascendant trend year by year.
The meticulous plasma cutting technique of class laser is the pith of cutting processing application, is one of advanced in the world at present cutting technique, also is the trend of cutting industry technology development.In recent years, the class laser technology began to be applied to the cutting of thin plate in the metal.Compare with traditional oxy-acetylene, plasma arc cutting, the class laser cutting has that speed is fast, joint-cutting is narrow, the heat affected area is little, the joint-cutting edge-perpendicular is smooth, economy advantage such as save time again.The sheet material otch roughness Ra≤6.3 μ m that go out with the class laser cutting, otch perpendicularity≤1 °, kerf quality reaches the lower range of laser cut quality, and the slot width is about common isoionic 1/2, the common plasma of cut lengths ratio of precision doubles approximately, and cutting speed is higher than laser, when cutting cut deal especially, be common isoionic 57 times considerably beyond common plasma the service life of electrode, nozzle.Class laser cutting device cost of investment and operating cost only are 1/4 ~ 1/10 of laser cutting machine, and the scope of its cutting material is very wide, but carbon steel, stainless steel, steel alloy and non-ferrous metal etc.
The cutting torch of CUT is for carrying out the critical component of cutting task, in the cutting working environment of complexity, because operator's range of observation is limited, cutting torch often is collided, damage cutting torch easily, need often to change nozzle and motor, increase many use costs.
The utility model content
The purpose of this utility model is to provide a kind of cutting torch protective device of simple in structure, service-strong CUT.
The technical scheme that realizes the utility model purpose is:
A kind of plasma cutting-torch protective device; has base; above-mentioned base top is provided with protective cover; protective cover comprises the upper spring pressing plate and the lower spring pressing plate of upper and lower settings; be provided with stage clip between the upper and lower spring bearer plate; above-mentioned lower spring pressing plate contacts with base, is connected by steel cable between upper spring pressing plate and the base.
The faying face place of above-mentioned base and lower spring pressing plate is provided with near switch.
Benefit of the present utility model is that plasma cutting-torch is installed in the protective cover, at first runs into protective cover when other object collision cutting torches, has protected cutting torch to avoid damage, and protective cover employing Flexible Design, resets easily after bumping; The inwall of cutting torch base is provided with near switch, when protective cover is collided, can send information near switch, stops cutting operation, guarantees that collision can not influence cutting accuracy.
Description of drawings
Fig. 1 is this novel structural representation.
The specific embodiment
See Fig. 1, this is novel to have base 5, and base is fixedlyed connected with cutting torch grip block 100, under the cutting torch lowering or hoisting gear 101 of CUT acts on, the cutting torch grip block will rise or descend, and is installed in the middle cutting torch of base and also moves up and down with cutting torch grip block 100.
The top of above-mentioned base is a protective cover; protective cover comprises upper spring pressing plate 1, lower spring pressing plate 2, stage clip 3 and steel cable 4; upper and lower spring bearer plate upper and lower settings; stage clip is between upper and lower spring bearer plate; the stage clip of upper and lower spring bearer plate is placed the position and is had groove; the normal condition stage clip is in compressive state, and steel cable connects upper spring pressing plate and base, and steel cable is in tension under the effect of stage clip.Above-mentioned lower spring pressing plate 2 lower ends have the inclined plane, and the upper surface of base has the inclined-plane that cooperates with the inclined plane of lower spring pressing plate lower end, does the time spent when protective cover is subjected to external force, and relative motion can take place for lower spring pressing plate and base, and protective cover is run-off the straight just.
Plasma cutting-torch is fixedly mounted between the upper and lower spring bearer plate, does the time spent when protective cover is subjected to external force, and cutting torch tilts together with protective cover.Faying face place between above-mentioned base and the lower spring pressing plate is provided with near switch; when protective cover is collided run-off the straight together with cutting torch; base and lower spring pressing plate faying face expose the gap; send signal near switch and give control system; stop cutting operation; and the lifting cutting torch, guarantee when cutting torch is disturbed by external force, not carry out cutting work, avoid influencing cut quality.
Claims (2)
1. plasma cutting-torch protective device; has base (5); it is characterized in that: above-mentioned base top is provided with protective cover; protective cover comprises the upper spring pressing plate (1) and the lower spring pressing plate (2) of upper and lower settings; be provided with stage clip (3) between the upper and lower spring bearer plate; above-mentioned lower spring pressing plate contacts with base, is connected by steel cable (4) between upper spring pressing plate and the base.
