Embodiment：
In the present embodiment, in the manufacturing method of central air-conditioning heat exchanger package, the detailed mistake of generation numerical control marking instruction
Cheng Wei：
First, the graphics of heat exchanger is drawn in three-dimensional software POR systems, graphics is needed according to actual shape of product
And size is planned, is unfolded first with designed POR graphics and (has specific backing positions on graphics), so as to
It determines to need the specific location for carrying out stent welding on heat exchanger package；
2nd, graphics is changed into X-Y scheme (cad figures), the ratio of X-Y scheme and actual product is 1：1；
3rd, by FastCAM jacking softwares, jacking, programming are carried out, generation numerical control marking instruction has been thereby determined that branch
Frame welding position carries out the operational order beaten dashdotted operational order and cut according to plate size to be processed.
Controller controls to get rifle ready and moved and got ready the detailed process of mark according to instruction：
First steel plate to be processed is placed in machine table, flat plasma cutting equipment is then controlled by controller
Rifle is got ready to move on the steel plate, select datum mark (any position of steel plate can, but be in order at the mesh for saving material
, by benchmark point selection at edges of plate position).After determining datum mark, get ready rifle according to it is above-mentioned get ready line instruct into
Row movement, after being moved to the position for needing to carry out stent welding, according to connection contact shape of the stent in the position, to be processed
What panel surface impacted respective shapes gets line figure ready.Complete first stent get line ready after, it is a kind of there are two types of mode
Be get ready rifle move directly to it is next need beat dashdotted position operated；Another kind is to get rifle ready to briefly return to benchmark
Point, then be moved to it is next need beat dashdotted position operated.The benefit of the second way is to ensure each position
Accurately got ready.
Get ready rifle complete all positions get line ready after, return to datum mark.Then rifle will be got ready with cutting gun to be turned
It changes, makes cutting gun face datum mark, then cutting gun proceeds by mobile cutting according to cutting instruction from datum mark, is cut into big
The shell of small suitable heat exchanger.
It is rolled after completing cutting, forms heat exchanger package, stent size and position can accurately be shown on package
Show, this method realizes automation cutting and automatically dotting labelling technique.
Stent size and the accurate marker of position are already had on the shell, need to only be propped up on corresponding mark
The welding of frame avoids traditional to scheming, measuring, the manual operations such as rule.
The manufacturing method of the present embodiment central air-conditioning heat exchanger package, mainly solves the problems, such as exactitude position, in shell
Just first the specific location of stent is marked before body steel plate cutting process, ensures product quality.The program realizes automation cutting
With automatically dotting labelling technique, impact is carried out by the way of to surface of shell slight damage and is got ready, so as to avoid follow-up shell
The influence of body sandblasting, impeller blasting technique to housing line effect, ensures each dimensional accuracy in package manufacturing process, is empty
Adjust advanced method for manufacturing in industry.
Embodiment described above only expresses embodiments of the present invention, and description is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art,
