Abstract
The invention discloses a manufacture technology of box feet of a hanging type hatch cover, wherein the right-angle edge of a third plate is outwards inclined by 3mm, so that theta in the third plate is 93.47 degrees; the third plate is flatly paved on a tire frame, a first plate and a second plate are assembled on the third plate, and the first plate, the second plate and the third plate are fixed with one another in a point welding way; the whole third plate is overturned by a plate hook; after the whole third plate is overturned, a forth plate is assembled on the third plate, and the third plate and the forth plate are fixed with each other in a point welding way; a whole component is hoisted to a welding region, so that the whole component is placed on the tire frame, the forth plate is faced to the tire frame, and the first plate and the second are deviated from the tire frame; a fillet weld between the first plate and the third plate, a fillet weld between the second plate and the third plate, and a fillet weld between the third plate and the forth plate are sequentially welded; and after the welding is completed, all the welded angular deformation can be leveled by a firer, and the whole flatness of the third plate can be leveled due to the generation of the angular deformation. The manufacture technology has the advantages that the processing step is simple, the welding workload can be reduced, the generation of the phenomenon of the bulking of a web plate can be avoided, and the workload of the firer can be reduced.
Description
technical field:
The present invention relates to a kind of manufacture craft hanging the case pin of formula hatchcover.
background technology:
At present, in the manufacture craft of the existing case pin hanging formula hatchcover, by each accessory size according to drawing requirement blanking, right angle portions is according to 90 ° of blankings, polished by free margins after blanking, assembling after polishing, welding, firer correct, and after correcting, the end opening of usual 3rd plate can little 4-8mm, cause being assembled on top board at this component, by web and panel-mounted to the both sides of the 3rd plate, have the gap of 3-5mm, welding job amount strengthens, welding trailing web plays drum, and it is larger that firer corrects difficulty.
summary of the invention:
The object of the invention is to overcome above deficiency, providing the manufacture craft that a kind of processing step is simple, reduce welding job amount, avoid web to play bulging phenomenon producing, reduce the case pin of the formula that the hangs hatchcover of hot work amount.
Object of the present invention is achieved through the following technical solutions: a kind of manufacture craft hanging the case pin of formula hatchcover, and concrete steps are as follows:
A, lean outward the right-angle side of the 3rd plate 3mm, makes the θ in the 3rd plate be 93.47 °;
B, the 3rd plate is laid on moulding bed, marks the assembly line of the first plate and the second plate, on the 3rd plate, assemble the first plate and the second plate according to this line, afterwards the first plate and the second plate spot welding are fixed on the 3rd plate;
C, use plate hook hang and are stood up by monoblock the 3rd plate;
D, stand up after, the 3rd plate plate marks the assembly line of the 4th plate, the 4th plate is assembled on the 3rd plate, afterwards the 4th plate spot welding is fixed on the 3rd plate;
E, by whole component handling to welding region, be placed on moulding bed by whole component, the 4th plate is towards moulding bed, and the first plate and the second backboard are from moulding bed;
F, first weld the angle welding of the first plate and the 3rd plate, and then weld the angle welding of the second plate and the 3rd plate, during angle welding, all adopt the manual welding of carbon dioxide;
G, whole component stand up, the angle welding of welding the 3rd plate and the 4th plate;
After H, all welding complete, owing to producing angular deformation, firer corrects the angular deformation of all welding, the whole flatness of smoothing the 3rd plate.
The present invention compared with prior art has the following advantages: the 3mm due to the 3rd plate flare, makes 90 ° of original angles become 93.47 °, avoid assembled in situ excesssive gap, decrease the consumption of welding job amount and wlding, also reduce hot work amount.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A to structural representation;
Number in the figure: 1-first plate, 2-second plate, 3-the 3rd plate, 4-the 4th plate.
detailed description of the invention:
in order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
As Fig. 1 and Fig. 2 shows a kind of a kind of embodiment hanging the manufacture craft of the case pin of formula hatchcover of the present invention, concrete steps are as follows: lean outward the right-angle side of the 3rd plate 3 3mm, makes the θ in the 3rd plate 3 be 93.47 °; 3rd plate 3 is laid on moulding bed, marks the assembly line of the first plate 1 and the second plate 2, on the 3rd plate 3, assemble the first plate 1 and the second plate 2 according to this line, afterwards the first plate 1 and the second plate 2 spot welding are fixed on the 3rd plate 3; Use plate hook to hang monoblock the 3rd plate 3 is stood up; After standing up, the 3rd plate plate 3 marks the assembly line of the 4th plate 4, the 4th plate 4 is assembled on the 3rd plate 3, afterwards the 4th plate 4 spot welding is fixed on the 3rd plate 3; By whole component handling to welding region, be placed on moulding bed by whole component, the 4th plate 4 is towards moulding bed, and the first plate 1 and the second plate 2 deviate from moulding bed; First weld the angle welding of the first plate 1 and the 3rd plate 3, and then weld the angle welding of the second plate 2 and the 3rd plate 3; Whole component stands up, the angle welding of welding the 3rd plate 3 and the 4th plate 4; After all welding complete, owing to producing angular deformation, firer corrects the angular deformation of all welding, the whole flatness of smoothing the 3rd plate 3.The manual welding of carbon dioxide is all adopted during angle welding.
After whole structure manufacture completes, at the upper surface assembling top board of the 3rd plate, and then from side assembling web and panel, opposite side also assembles web and web, and the lower surface of web is connected with panel.
The 3mm due to the 3rd plate flare, makes 90 ° of original angles become 93.47 °, avoids assembled in situ excesssive gap, decrease the consumption of welding job amount and wlding, also reduce hot work amount.
