Abstract
The invention relates to a rapid joint forging process and a forging die. The process comprises the following steps of: arranging a heated blank on the upper middle part of a lower die, assembling the die and applying pressure, so that the upper die and the lower die are contacted on a pressure-bearing table; opening the upper die, remaining a forging piece in the lower die, starting an ejection device below equipment, ejecting a lower die insert, and allowing two inserts to rise along with an inclined hole of the lower die and be close to the middle, so that the lower die insert is withdrawn out of a groove in the forging piece, taking out the forging piece, making an ejection plate descend, and resetting the lower die insert under the stretching action of a spring. The forging die for implementing the method comprises an upper template, an upper die core, an upper die, a lower template and a lower template. The rapid joint forging process has the advantages that the forming method and forming process are changed, so that the yield of the product is over 98 percent; the product has high compactness, high mechanical property and long service life; the product is formed at a time through a pair of dies, and the forming time and cost of the die are reduced; the product is not required to be subjected to metal working after being formed; and moreover, the die is convenient to use and mount, and the operation is easy and reliable.
Description
Technical field
The present invention relates to a kind of snap joint Forging Technology, also relate to a kind of forging mold of realizing above-mentioned Forging Technology.
Background technology
General fire hose is the aluminium alloy casting moulding with snap joint, and aluminium alloy produces various defectives because many factors is easy in casting process, thereby causes: decrease in yield, and the product mechanical property is undesirable, and service life is not long.
Because product geometry more complicated, inner quick-locking mechanism is the internal channel structure, and the part effective dimensions is less, and cooling velocity is very fast.Conventional mould forges and has two large difficult points: forging internal channel demoulding difficulty; Finish forging and molding and often need two secondary moulds (first blocking base is forging forming again).
Summary of the invention
Technical problem to be solved by this invention provides a kind of one-time formed contour forging technique and particular manufacturing craft.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of snap joint Forging Technology, and its wound is first: described processing step is: the blank of heating is positioned over middle part on the counterdie, and matched moulds is also exerted pressure, make upper and lower mould pressure-bearing platform contact, the forging moulding; Open patrix, forging is stranded in counterdie, the opening device bottom ejection device, eject counterdie and insert, insert for two and also close up to the centre simultaneously along the rising of counterdie inclined hole, counterdie is inserted extracted out the forging internal channel, take out forging, fall the liftout dish, counterdie is inserted to drive under the effect that spring stretches and is resetted.
A kind of forging mold of realizing above-mentioned snap joint Forging Technology, its innovative point is: comprise cope match-plate pattern, upper mold core, patrix, lower bolster, counterdie, upper mold core is arranged in the patrix, patrix is installed in the lower surface of cope match-plate pattern, under cope match-plate pattern, be provided with lower bolster, counterdie is installed in the upper surface of lower bolster, the two ends of the upper surface of counterdie are equipped with positioning guide column, open the hole that the appearance positioning guide column stretches at the correspondence position of patrix, counterdie is provided with counterdie and inserts, under the lower end of lower bolster is provided with, take over a business, lower take over a business with lower bolster between be connected push rod under being provided with, cover has Compress Spring on the lower connection push rod.The invention has the advantages that: by changing forming method and moulding process, the yield rate of product reaches more than 98%, and former process is about 85%; The compactness of product strengthens, and mechanical property is better, longer service life; Product one secondary mould, one-shot forming have reduced shaping time and die cost; Need not metalworking after the formed product; Mould is easy to install and use, operates simple and easy reliable.
Description of drawings
Fig. 1 is the schematic diagram of snap joint forging mold of the present invention.
The specific embodiment
By the described schematic diagram of Fig. 1 as can be known, forging mold of the present invention comprises cope match-plate pattern 1, upper mold core 3, patrix 2, lower bolster 6, counterdie 5.
Upper mold core 3 is arranged in the patrix 2, patrix 2 is installed in the lower surface of cope match-plate pattern 1, patrix 2 and cope match-plate pattern 1 are fixed by bolt, under cope match-plate pattern 1, be provided with lower bolster 6, lower bolster 6 is fixed by T-shaped slot bolt 10, counterdie 5 is installed in the upper surface of lower bolster 6, be fixed by bolt between counterdie 5 and the lower bolster 6, the two ends of the upper surface of counterdie 5 are equipped with positioning guide column 4, open the hole 8 that appearance positioning guide column 4 stretches at the correspondence position of patrix 2, be provided with counterdie in the counterdie 5 and insert 9, under being provided with, the lower end of lower bolster 6 takes over a business 7, under take over a business 7 with lower bolster 6 between be connected push rod 13 under being provided with, lower connection push rod 13 matches with whorl brace rod 12, whorl brace rod 12 stretches into the inside of lower bolster 6, connect to overlap on the push rod Compress Spring 11 is arranged, one end of Compress Spring 11 is against on the lower surface of lower bolster 6, and the other end is connected with nut.
Snap joint Forging Technology among the present invention is specially:
The blank of heating is positioned over middle part on the counterdie, and matched moulds is also exerted pressure, and makes upper and lower mould pressure-bearing platform contact, the forging moulding;
Open patrix, forging is stranded in counterdie, the opening device bottom ejection device, eject counterdie and insert, insert for two and also close up to the centre simultaneously along the rising of counterdie inclined hole, counterdie is inserted extracted out the forging internal channel, take out forging, fall the liftout dish, counterdie is inserted and is resetted under the effect that spring stretches.
