Detailed description of the invention
With reference to the accompanying drawings in detail the present invention is described in detail.
Inclined-plane of the present invention anvil is made up of upper anvil portion and lower anvil portion, upper anvil portion is made up of upper anvil and upper anvil block, lower anvil portion is made up of lower anvil 3 and lower anvil block 4, the bottom of upper and lower anvil, shaped upper part consistent with Machining of Connecting Rod conical surface shape (see Fig. 2,4).
With reference to Fig. 1,2,5, the dovetail 7 of the upper anvil 1 (Fig. 1) of upper anvil portion sticks in the dovetail groove 8 of anvil block 2, and by the taper iron wedge 13 inserted, and both are fixed as one by the flat key 14 injecting upper anvil keyway 12 and upper anvil block keyway 11.
With reference to Fig. 3,4,6, the keyway 9 that narrow limit 10 is placed in lower anvil block is protruded in the side of the lower anvil 3 of lower anvil portion.
On, lower anvil is made up of two symmetrical inclined-planes and a flat face, for prevent forging time can produce folding, on, two inclined-planes of lower anvil and neutral straight face and on, all arc transition is adopted between lower former and later two faces of anvil, eccentric forging may be produced when considering that inclined-plane forges, damage hydraulic press body, on, two inclined-planes of lower anvil adopt symmetrical, on, the angle of lower anvil inclined-plane and horizontal plane and bevel altitude are according to shaping back link frustoconical bevel angle and size design, according to intermediate shank portion open grade shape and on, the replacing of lower anvil is convenient, on, lower anvil does not fall when moving on walking on stage, therefore suitably increase bottom surface flat side.
By the method for the inclined-plane anvil processing transition conical surface of the connecting rod rough forging transition conical surface, concrete steps are as follows:
The dovetail 7 of anvil on inclined-plane 1 (Fig. 1) is sticked in the dovetail groove 8 of upper anvil block 2, inserting taper iron wedge 13 makes the two fixing, and then flat key 14 injected upper anvil keyway 12 and both fix by upper anvil block keyway 11, upper anvil block 2 is bolted is connected on press connecting plate 6.
Lower anvil side is protruded narrow limit 10 to align with the keyway 9 of lower anvil block, lower anvil 3 (Fig. 2) is put into lower anvil block 4, place it on press walks on stage, after being assembled by upper and lower anvil, operation press, makes anvil 1 upper surface and lower anvil 3 upper surface align.
With reference to Fig. 4, with the jaw clamping blank of blank manipulator, rotary billet is carried out by rotary billet manipulator jaw, rotary billet on one side, while step on the mid portion of blank with upper and lower anvil, attentional manipulation drafts, the deflection that guarantee forging is each is as far as possible similar to, to prevent bias, ensure the shape of forging rule, simultaneously, the intermediate incline 5 at connection-rod portion and two is also pressed into the conical surface (Fig. 5) by the inclined-plane on upper anvil 1 and lower anvil 3 two sides for the upper plane of upper anvil 1 and the partially-formed connecting rod intermediate shank portion of the lower plane of lower anvil 3.
Finally change upper and lower flat anvil finishing shaping connecting rod each several part, open a grade part in the middle of being shaped with upper and lower flat anvil connecting rod rough forging, first number print extrudes middle transition step four times, at impression four mid portions, and the round as a ball shaping connecting rod middle transition conical surface.
The operation of the number of present invention eliminates print, direct forming intermediate shank portion and intermediate incline, also according to the different type of machines of connecting rod, can change length and the bevel angle of shape anvil plane, forge the different transition conical surfaces.
The present invention can produce the connecting rod of 50 machines and above marine diesel different types of machines.Type comprises 6 × 72,6S50ME-B, 6S50ME-B9,6S50ME-B9.2,6S50ME-B9.3,5S60ME-C 8.2,6S60ME-C8.2,8S60ME-C8.2,5S60ME-C, 6S60ME-C, 6S70ME-C, 6S70ME-C8.2,6G80ME-C, 7S80MEC, 10s90MEC.
