Abstract
The invention provides a manufacturing method of integrated square fire-resisting damper valve buckle body molding, comprising the following process steps: carrying out blanking on a complete board with a plate shearing machine according to the ordered size of the valve body and cutting into a rectangular panel veneer; carrying out working procedure processing like corner cutting, notching, punching and the like on the panel veneer with a press tool; performing bending operation of the flange edge at the two sides of the panel veneer with a bending machine; carrying out molding operation on the square frame body with a valve body molding device; and finally adopting welding or riveting operation at the seam position to finish the processing of the valve body frame body in the end. The invention has the following advantages: the method only needs shearing the board once, and the manufacturing can be completed through press working; compared with the current board-shearing and tailor welding four times, the method in the invention leaves out a plurality of working hours and reduces the disadvantages of size deformation; the total processing time of the frame body can be saved by 59.5%, thus the cost of the valve body is substantially lowered; the integrated board is under press working with almost no deformation; and welding is only carried out on the joint at one side, and the generated air leakage rate of the weld porosity is reduced to 25% of the original air leakage rate.
Description
Technical field
What the present invention relates to is a kind of preparation method and rolling forming device thereof of framework of the square fire resisting damper that is used to connect airduct.Belong to the HVAC product technical field.
Background technology
Current technology, framework is formed by the sheet material or the section bar welding on four limits, and this can cause following defective:
The blank size of material is many, obscures for anti-, and during volume production, management cost increases; Four weldings, the seam crossing processing dimension has distortion, and processing cost also increases; Four weldings, process time is higher, and production cost increases, and is difficult for volume production.
Summary of the invention
What the present invention proposed is the preparation method and the rolling forming device thereof of integrated square fire-resisting damper valve buckle body molding, is intended to overcome the existing defective of existing product preparation method, and it is little that this method has a size distortion, overall appearance.Whole plate processing, structural rigidity is strengthened; Preface reduces, and adapts to volume production.
Technical solution of the present invention: the preparation method of integrated square fire-resisting damper valve buckle body molding comprises following processing step:
One, a whole plate is pressed the size that valve body is ordered goods with plate shearing machine, carries out blanking, is cut into the rectangle plate;
Two, then on plate, carry out corner cut, towards lacking the processing of operations such as punching with the stamping die that customizes;
Three, carry out the bending operation of flange then in the both sides of plate with bender;
Four, use the valve body former to carry out the forming operation of square framework then;
Five,, adopt welding or riveting operation (deciding), finally to finish the processing of valve body frame body on customer requirement and valve body size at last at seam crossing.
Advantage of the present invention: the method only needs a shear, just can finish making by pressure processing.With respect to four times existing shears, four weldings save some man-hours, and distortion reduced in size are unfavorable.Concrete numerical value following (thick with fire resisting damper 250 is that benchmark describes):
1) be existing man-hour:
During the four edges blankers 6 seconds * 2 people * 2 limit * 4=96 seconds
Article four, to need man-hour be 250/3*4=333 second for seam welding
Add up to 96+333=429 second above man-hour
Improving the back is man-hour:
During plate blankers be: 6 seconds * 2 people * 2 limits=24 seconds,
The technology groove of roll forming (dash to lack, corner cut, punching) is 9 groups of * 1 people of 4 seconds *=36 seconds man-hour,
Article three, the limit roll forming is man-hour: 10 seconds * 1 people * 3 limits=30 seconds,
Article one, the limit welding is man-hour: 250/3*1=84 second,
Add up to 24+36+30+84=174 second above man-hour,
So can save man-hour after improving is 1-((429-174)/429)=59.5%.
This shows, after the integrated improvement, framework can save total process time 59.5% thereby the valve body cost significantly reduce.
2) existing framework is formed by 4 block weldings, and high temperature makes sheet material produce distortion, the bad control of size.After the improvement, adopt whole plate pressure processing, almost do not have distortion, size can better be controlled.Make valve body more attractive in appearance; Other has only on one side that joint adopts welding possibly, so connect with respect to 4 existing side welds, the weld porosity leak rate of generation drops to original 25%.
