Abstract
The utility model discloses a vacuum cavity for cutting equipment, comprising a base and a body integrally moulded on the base, wherein a corresponding process hole is arranged on the base, the section of the body is triangular, and a corresponding process hole is arranged on the body. The vacuum cavity for cutting equipment disclosed by the utility model is novel in structure, strong in practicability, and capable of achieving the demands needed by a laser cutting machine.
Description
Technical field
The utility model relates to a kind of cutting equipment, is specifically related to a kind of vacuum cavity that is used for cutting equipment.
Background technology
Liquid crystal display (Liquid Crystal Display) glass substrate is a kind of special glass material of ultra-thin, large format, is the key element that constitutes display panels.In order to improve the yield rate of glass substrate, reaching the cost that saves material, the purpose of enhancing production capacities, each factory commercial city seeking a kind of fast, efficient, clean glass substrate.
For the cutting of glass substrate, generally adopt the liquid crystal display laser cutting machine, this cutting machine generally also can be used for the cutting processing that mobile phone, computer, liquid crystal display etc. show glass.
The cutting glass by laser substrate is a complex laser and the interactional process of material.This process comprises that the laser moving heat source changes the generation thermal stress to thermal transient conduction, the temperature gradient that material heats, and utilizes thermal stress to induce the crackle expansion until fracture, thereby cuts apart glass substrate.
In cutting process, heating is rapidly then cooled off rapidly again under convection current and heat conducting effect because material is excited light beam irradiates, thereby can cause the imbalance that the material internal stress field distributes, and then causes the uncontrollable of crackle, influences cut quality.The numerical simulation of cut stress field is optimized cutting technique and is had important effect grasping the DYNAMIC DISTRIBUTION of cutting process stress field.
The temperature gradient that laser cutting technique causes when material surface scans through laser beam changes the generation thermal stress; When stress value reaches certain threshold value; Can make material surface crackle occur; And can control direction expansion that this crackle advances along laser beam until fracture, thereby separating materials, have that cutting section is level and smooth, one-shot forming, to advantages such as raw material character and form influence are less.
The increase of cooling flow can improve to cutting speed.And reduce when cooling off the distance of point with hot spot, laser output power descends (cutting speed is certain) or cutting speed improves (laser output power is certain).After increase cooling flow or shortening cooling point and the hot spot distance; The rising-heat contracting-cold effect aggravation of material; Make tensile stress value reach the fracture strength limit very soon thus; And make crackle rapidly expansion so just make glass substrate be easy to cutting until fracture, corresponding cutting speed be improved (or required rupturing duty reduces).
Can know that by last technical scheme the performance quality of laser cutting machine will directly influence last cutting effect.Wherein vacuum cavity is the important component part in the existing laser cutting machine, but vacuum cavity of the prior art can't reach the needed requirement of laser cutting machine, influence its overall performance.
The utility model content
The utility model is directed against the existing existing problem of vacuum cavity, and a kind of novel vacuum cavity is provided, to overcome the existing in prior technology problem.
In order to achieve the above object, the utility model adopts following scheme:
A kind of cutting equipment is used vacuum cavity, and said cavity comprises base and one-body molded body composition on base, and corresponding fabrication hole is set on the said base, and the cross section of said body is a triangle, and said body is provided with corresponding fabrication hole.
Further, the fabrication hole on the said base is distributed in the centre position.
The utlity model has following advantage according to what technique scheme obtained:
(1) simple in structure, be convenient to produce;
(2) superior performance reaches the required requirement of laser cutting machine;
(3) novel structure, utility model is strong.
Description of drawings
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
In order to solve the problem that existing vacuum cavity can't satisfy the laser cutting machine performance requirement, the utility model provides a kind of novel cutting equipment to use vacuum cavity.
Referring to Fig. 1, this cavity 100 comprises base 101 and corresponding cavity body 102.
These body 102 integrally formed being arranged on the base improve its overall performance like this.
Moreover, according to its functional requirement corresponding fabrication hole 103 is set on base 101, and this fabrication hole 103 is distributed in the centre position.
At last according to performance and functional requirement, the body 102 that relates in the utility model, its cross section is a triangle, body is provided with corresponding fabrication hole 104 simultaneously.
The cavity that the utility model provides, its integral body all adopt stainless steel to process, and this improves its performance greatly.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
