Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
For convenience, have employed upper and lower grade and state with the word in orientation in present patent application file, the word in all band orientation is all characterize according to the orientation of the Fig. 1 in Figure of description.
As shown in Figure 1, Figure 2 with shown in Fig. 3 and Fig. 4, the clamping device of hotdie forging press upper bolster of the present invention, comprises supporting mass 1, piston 2, intermediate connector 3, swinging block 4, swinging block driving mechanism 5 and piston drive mechanism; Described supporting mass 1 has closed cavity, described piston 2 is placed in described closed cavity, described closed cavity is divided into upper plenum and lower cavity by described piston 2, the piston rod be connected with described piston 2 is through the diapire of described supporting mass 1, and described piston drive mechanism driven plunger 2 moves in closed cavity; Described swinging block 4 one end is link, and the other end is free end, and described intermediate connector 3 one end is connected with piston rod, and the other end is hinged with the link of swinging block 4 by connecting pin 6, and the free end of described swinging block 4 is the font of falling T; Described swinging block driving mechanism 5 drives swinging block 4 to swing around connecting pin 6.
As shown in Figure 1, Figure 2 with Fig. 3 and Fig. 4, upper plenum refers to the cavity between piston 2 upper surface and the roof of supporting mass 1, and lower cavity refers to the cavity between piston 2 lower surface and the diapire of supporting mass 1.Described supporting mass 1 one aspect is for supporting the gravity of the clamping device of whole hotdie forging press upper bolster, on the other hand as the cavity of piston 2, generally, described supporting mass 1 comprises supporting body 101 and top cover 102 two parts, top cover 102 and supporting body 101 can pass through bolt, the modes such as screw connect, be convenient to install and change piston 2, described supporting body 101 is barreled structure, top cover 102 coordinates formation cavity with supporting body 101, between described supporting body 101 and top cover 102, between the madial wall of piston 2 and supporting mass 1, seal is provided with between the diapire of piston rod and supporting mass 1, the effect of described piston drive mechanism promotes piston 2 to the roof direction motion of supporting mass 1 or promote piston 2 and move to the diapire direction of supporting mass 1, generally, be not easy to directly offer pin-and-hole on the piston rod, therefore, adopt intermediate connector 3 as the transition piece of piston rod and swinging block 4, middle intermediate connector 3 can be connected with piston rod by screw thread, compressed by standby pressure nut 11 again, hinged by connecting pin 6 between intermediate connector 3 and swinging block 4, like this when swinging block driving mechanism 5 provides the moment making swinging block 4 swing around connecting pin 6, swinging block 4 just can rotate around connecting pin 6, swinging block driving mechanism 5 provides the power that swinging block 4 is swung around connecting pin 6, thus control the inverted T shape groove that swinging block 4 swung in and showed upper bolster 10.Described swinging block driving mechanism 5 can adopt cylinder or hydraulic cylinder, can control swinging block 4 like this swing around connecting pin 6 by cylinder or hydraulic cylinder.
As shown in Figure 2, Figure 3 and Figure 4, when using the clamping device of hotdie forging press upper bolster of the present invention, by the mode of bolt, screw or welding, supporting mass 1 is connected with slide block 9, the font of falling T of swinging block 4 free end matches with the inverted T shape groove on upper bolster 10, during hotdie forging press work, the font of falling T of described swinging block 4 free end embeds in the inverted T shape groove on upper bolster 10, described piston drive mechanism promotes piston 2 and moves to the roof direction of supporting mass 1, thus upper bolster 10 is clamped on slide block 9, now upper bolster 10 is in clamped state, when hotdie forging press needs to change die holder, described piston drive mechanism promotes piston 2 and moves to the diapire direction of supporting mass 1, upper bolster 10 is made to be in releasing orientation, now swinging block 4 is driven to rotate around connecting pin 6 by described swinging block driving mechanism 5, the free end of swinging block 4 is shown in the inverted T shape groove of upper bolster 10, in time making the free end of swinging block 4 depart from upper bolster 10 completely, upwards mention slide block 9 again, thus make upper bolster 10 and slide block 9, the clamping device of hotdie forging press upper bolster departs from completely, now again upper bolster 10 is pulled out from the front of hotdie forging press and change, after replacing, upper bolster 10 is pushed into and aligns with slide block 9, swinging block 4 is driven to swing in the inverted T shape groove of upper bolster 10 by described swinging block driving mechanism 5, then promote piston 2 by piston drive mechanism to move to the roof direction of supporting mass 1, thus upper bolster 10 is clamped on slide block 9.Because the clamping device of drop press upper bolster of the present invention is in the process clamped and unclamp, promotes piston 2 by piston drive mechanism and move, make upper bolster 10 be in clamped state or releasing orientation; Drive swinging block 4 to rotate around connecting pin 6 by swinging block driving mechanism 5, make the free end of swinging block 4 swing in or show the inverted T shape groove of upper bolster 10.Therefore, the clamping device of drop press upper bolster of the present invention is compared with the clamping device of the drop press upper bolster of prior art, have that structure is simple, easy to operate, die change efficiency is high, manufacture and the advantage such as maintenance cost is low, adopt the clamping device of drop press upper bolster of the present invention, the flow process that can simplify the operation, enhance productivity, reduce labour intensity and production cost.
