Description
Technical field
The utility model relates to a kind of preparation method and mould of blank flange, belongs to panel beating and stress metal processing technique field.
Background technology
At present, the process of making flange has a lot, as: forge flange, cast flange, roll flange etc.A large amount of flange arrangements that use in transformer industry, along with the increase of product capacity, the employed flange diameter of oil tank of transformer also increases thereupon, and background technology is to utilize the whole blanking of steel plate, and cost is higher.
The utility model content
The purpose of the utility model provides a kind of making mould of blank flange, and is practical, improves the utilization rate of material, reduces cost, and solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: the making mould of blank flange, comprise the part of the upper die and the part of the lower die of mutual coupling, and the part of the upper die is made up of die shank and last arc punch, gets up through bolted, and die shank is installed on the press ram and moves reciprocatingly; The part of the lower die is made up of head part plate, die shoe, elasticity head part demoulding device and the stock guide of shelves material pin, arc lower die, band push rod, gets up through bolted respectively between arc lower die and stock guide, stock guide and the die shoe; About stock guide each one, with the feeding direction of control billot, shelves material pin is fixed in the arc lower die, is used for controlling correctly sending to of billot.
The internal diameter size of flange is guaranteed that by last arc punch outside dimension is guaranteed by the arc lower die.When the flange of processing different size and thickness, only need change arc punch, arc lower die and head part plate and get final product, therefore have certain versatility.
The head part plate of band push rod links to each other with the guide rod frame of band guide rod, and the guide hole on guide rod and the arc lower die is slidingly matched, and guide rod frame lower end is provided with elastic caoutchouc or spring, and elasticity head part demoulding device is arranged on the die shoe, and die shoe is fixedly connected with the arc lower die.
Adopt the utility model machining blanks flange, comprise following operation: a, be broken down into some strip parts according to the girth of flange; B, above-mentioned every part billot is sheared or cutting stock; C, adopt process for stamping to make it produce bending distortions with equal curvatures along its in-plane to descending billot; D, utilize SMAW or gas shielded arc welding above-mentioned segmentation blanking to be spliced into the flange shape of requirement at last.
After adopting process for stamping to make it produce bending distortions with equal curvatures to descending billot along its in-plane, X type bevel for welding is opened at the billot two ends, 30 ° ± 5 ° of bevels angle; After the splicing welding, butt welded seam carries out ultrasonic examination; , its in-plane considers its free resilience bend allowance when adopting process for stamping to make it produce bending distortions with equal curvatures; Support cunning or reduce free resilience with the bending with sizing method.
The good effect of the utility model: the characteristics that have utilization rate simple to operate, as to improve material, turn waste into wealth, save material, manufacture craft property is good, efficient is high, reduce cost, the making of the major diameter flange that is specially adapted to produce in batches.
Description of drawings
Fig. 1 is the utility model embodiment sketch map;
Fig. 2 is the utility model embodiment schematic side view;
Among the figure: the 1--die shank, 2-go up the arc punch, 3-billot, 4-shelves material pin, 5-arc lower die, the head part plate of 6-band push rod, 7-die shoe, 8-elasticity head part demoulding device, 9--stock guide.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
The making mould of blank flange comprises the part of the upper die and the part of the lower die of mutual coupling, and the part of the upper die is made up of die shank 1 and last arc punch 2, gets up through bolted, and die shank is installed on the press ram and moves reciprocatingly; The part of the lower die is made up of head part plate 6, die shoe 7, elasticity head part demoulding device 8 and the stock guide 9 of shelves material pin 4, arc lower die 5, band push rod, gets up through bolted respectively between arc lower die and stock guide, stock guide and the die shoe; About stock guide each one, with the feeding direction of control billot, shelves material pin is fixed in the arc lower die, is used for controlling correctly sending to of billot.
The internal diameter size of flange is guaranteed that by last arc punch outside dimension is guaranteed by the arc lower die.When the flange of processing different size and thickness, only need change arc punch, arc lower die and head part plate and get final product, therefore have certain versatility.
The head part plate 6 of band push rod links to each other with the guide rod frame of band guide rod; Guide hole on guide rod and the arc lower die 5 is slidingly matched; Guide rod frame lower end is provided with elastic caoutchouc or spring, and elasticity head part demoulding device 8 is arranged on the die shoe 7, and die shoe 7 is fixedly connected with arc lower die 5.
Process: forcing press is exerted pressure the arc punch is moved downward, and when last arc punch touched billot, last arc punch continues to press down made billot produce strain.Begin to produce plastic deformation along with last arc punch further moves downward after billot reaches yield limit, billot produces crooked.When beginning was crooked, the curved interior radius of billot was greater than the radius of last arc punch.Along with pressing down of last arc punch, the straight flange of billot and die surface are close to gradually.When last arc punch, billot overlap with the die three fully, the BENDING PROCESS of billot finishes.Through elasticity head part demoulding device the billot of making is ejected from die.Again X type groove is opened at the billot two ends, 30 ° of bevels angle adopt gas shielded arc welding to splice.Postwelding carries out ultrasonic examination according to GB/T 11345-1989 standard butt welded seam, percentage of detection 100%, and the III level is qualified.
