Description

Strip convex tendon aluminium alloy does not have the isothermal precision formed mould of molding gradient

One, technical field

The utility model relates to the isothermal precision formed mould of a kind of Al-alloy parts, and particularly a kind of strip convex tendon Al-alloy parts does not have the isothermal precision formed mould of pattern draft.

Two, background technology

Strip convex tendon Al-alloy parts is generally complex-shaped, precise forming processing is difficulty comparatively, usually adopt the hot forging moulding, but mismatch is big when being shaped, and the thermal contraction instability causes appearance and size precision difference big, and pattern draft arranged, therefore profile also needs machining just can reach Design Requirement Drawing, so that causes that manufactured goods machining surface and on-mechanical finished surface color and luster differ, thereby has increased the manufacturing cost of product and reduced product quality.

Three, summary of the invention

The purpose of this utility model aims to provide a kind of precision form processing no pattern draft, dimensional accuracy height to strip convex tendon Al-alloy parts product, surface roughness is low, surface color is consistent, and the protruding case of the strip metal spare that improves stock utilization and product yields, reduction cost of goods manufactured does not have pattern draft isothermal precise forming mold.

The purpose of this utility model is to adopt such technical scheme to realize, a kind of strip convex tendon aluminium alloy does not have pattern draft isothermal precise forming mold, it is characterized in that including combined die, lower bolster, ejector beam, die socket, guide finger, die backing plate, die plate insert, punch, punch case, convex mould pad, cope match-plate pattern, pin, trip bolt, packing ring, square key; Die face is the inclined-plane in the combined die, its internal mold bottom is provided with the die backing plate, die plate insert places on the interior die backing plate of combined die, the die backing plate places on the die socket, two guide fingers are arranged at die backing plate bottom, die socket is provided with pilot hole, and the pilot hole on guide finger and the die socket is slidingly matched, and combined die and die socket connect firmly by square key, trip bolt, packing ring and lower bolster location respectively; Punch is located in the punch case of convex mould pad bottom, connects firmly through pin, trip bolt, packing ring punch case, convex mould pad and cope match-plate pattern location.

During use the utility model is installed on the hydraulic press, the utility model and blank are heated, are incubated, when reaching isothermal moulding requirement to die of the present utility model and punch implement lubricated after, blank is put into die plate insert, start press, punch is exerted pressure to blank and is made blank be full of the die cavity shaping under controllable deforming speed, shaping end of a period punch lifts, jack-up die backing plate when ejector beam rises, and the jack-up die plate insert is divided right and left when the interior inclined-plane of combined die moves upward under guide finger guiding, takes out workpiece.Last die plate insert is at the downward matched moulds in interior inclined-plane of gravity effect lower edge combined die, behind the residue in removing die plate insert, repeats the continuous isothermal shaping operation that aforementioned forming process is carried out strip Al-alloy parts blank behind lubricated once more protruding, the die.The product that the utility model shapes does not have pattern draft, and accurate to dimension is higher, and the margin of tolerance is little, any surface finish, roughness are low, do not need machining again, thus the surface color unanimity, improve yield of products and stock utilization, reduced the manufacturing cost of product.

Five, the specific embodiment

Embodiment of the present utility model is described with reference to the accompanying drawings.As shown in drawings, a kind of strip convex tendon aluminium alloy does not have pattern draft isothermal precise forming mold, includes combined die 1, lower bolster 2, ejector beam 3, die socket 4, guide finger 5, die backing plate 6, die plate insert 7, punch 8, punch case 9, convex mould pad 10, cope match-plate pattern 11, pin 12,
