Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
The specific embodiment
To shown in Figure 5, a kind of mode transfer clamping described in the utility model mainly is comprised of some pull bars 2 and mold-locking and mold-adjusting assembly 3, pad 4, cohesion nut 5 and two adjustment blocks 6 that corresponding every pull bar 2 arranges at least as Fig. 1.
Every pull bar 2 is to slide be arranged in the moving platen 11 that dynamic model 12 is installed and be equipped with in the solid plate 13 of cover half 14.Every pull bar 2 is provided with one section annular tooth 21 on the pull bar body of rod in the moving platen outside, the outside of this section annular tooth 21 (relative with moving platen) radially forms a boss, the outside end face of this boss is contact end face 22, pad 4 be set on pull bar 2 and with contact end face 22 contacts, the outside end face role of this pad 4 is with to contact end face 22 suitable.
Each mold-locking and mold-adjusting assembly 3 is arranged on solid plate 13 and with an end of a pull bar 2 and connects.The mold-locking and mold-adjusting assembly 3 of the present embodiment is a pair of oil cylinder mold-locking and mold-adjusting assembly, mainly be comprised of high-voltage lock mould hydraulic pressure cylinder assembly 31 and fine setting mould hydraulic pressure cylinder assembly 32: fine setting mould hydraulic pressure cylinder assembly 32 is arranged on high-voltage lock mould hydraulic pressure cylinder assembly 31, its piston rod connects with an end of pull bar 2, be mainly used in cohesion nut to tooth; High-voltage lock mould hydraulic pressure cylinder assembly 31 is arranged on solid plate 13, is mainly used in applying the main frame mold clamping force.The concrete structure of the described mold-locking and mold-adjusting assembly 3 of the present embodiment can with reference to Chinese patent 201020572098.5,201020599259.X and 201010537757.6 disclosed mold-locking and mold-adjusting structures, not repeat them here.
Operating principle of the present utility model is: as shown in Figure 5, by the technique adjustment, the size H2 that makes adjustment block just is the integral multiple of annular teeth apart from P, guarantee the conflict end face of adjustment block and pull bar (pad) contact end contact the time cohesion nut tooth form aim at the tooth form of large pull bar to carry out the obvolvent action.
The course of work of the present utility model is as follows:
The oil pocket of 1, the course of work: a, fine setting mould hydraulic pressure cylinder assembly enters hydraulic oil, drives the pull bar certain distance that advances; B, drive moving platen and draw close to solid plate, this moment, cohesion nut was in open mode, when the conflict end face of the adjustment block on cohesion nut and pad contact end contact the time, cohesion nut carries out obvolvent, holds pull bar tightly; C, driving moving platen drive pull bar to be continued to draw close to solid plate, until dynamic model and cover half are fitted, should be noted during applying to guarantee that the oil pocket of finely tuning the mould hydraulic pressure cylinder assembly leaves a slight distance; D, high-voltage lock mould hydraulic pressure cylinder assembly advance pressure oil, carry out matched moulds; When e, die sinking, cohesion nut is opened, and drives moving platen and leaves, and a production cycle completes.
2, mode transfer process: when mold thickness changes, take minimum mold thickness as benchmark, guarantee the tooth that cohesion nut can substantial registration pull bar front end when mould is fitted; Require mold thickness to increase with the integral multiple of annular teeth apart from P, changing that size H2 that different adjustment blocks makes adjustment block reduces apart from the integral multiple of P with annular teeth (is that adjustment block is made a series of calibrated bolcks that change apart from the P integral multiple with annular teeth, be equipped with different adjustment blocks when changing when mould is thick), thereby when guaranteeing that mold thickness changes, the conflict end face of adjustment block and pad contact end contact the time cohesion nut tooth form can just aim at the tooth form of pull bar; Simultaneously in order to eliminate the mismachining tolerance of mold thickness H1, generally drive the advance distance of several tooth distances of pull bar at mould assembling action first step fine setting mould hydraulic pressure cylinder assembly, thereby after making the cohesion nut obvolvent, even do not fit because the mold thickness error may cause moving, cover half, thereby but moving platen still can drive pull bar moves to cover half and guarantee to fit.
The utility model is mainly used in the less situation of die adjustment scope, its main cause is in order to guarantee certain rigidity requirement, the size of adjustment block H2 is generally unsuitable excessive, but it is enough to be used for wheel hub extrusion modling industry, because the varied in thickness scope of aluminium wheel hub generally only has the 100mm left and right, adopt the utility model, can significantly reduce the cost of equipment.
