According to the two-stage press die cushion internally provided with the double guide rods, the problems that the conventional press die cushion is large in size, difficult to mount and maintain and poor in eccentric load resistance, stamping wastes or foreign matters enter the die cushion easily, the support plate requires whole replacement after deformed and the like are solved, and the practicability is high.
Description
Technical field
The present invention relates to a kind of punching machine die-cushion, specifically the forcing press twin-stage die-cushion of the two guide posts of a kind of inner band.
Background technology
General mechanical press die-cushion, is all mounted in the cavity of workbench below, and due to structural design, this cavity size is all compact conventionally, meet forcing press die-cushion Capability Requirement, and die-cushion is designed to the structure shown in Fig. 4 conventionally.The cylinder block 39 of this die-cushion and piston 38 are because size is larger, when assembling, need first to pack piston 38 into cylinder block 39, then be fixed on the sole position of fuselage 34, then from fuselage workbench top by support pad 36 through screw fastening plane in piston 38, then air cushion top board 35 is fixed on to the upper surface of support pad 36, finally the flange 37 that is divided into two halves is fixed on cylinder block 39 from the workbench below fore-and-aft direction of fuselage 34.
The vapour-pressure type die-cushion of this structure, has following distinct disadvantage:
1) installation, maintenance is very difficult, once die-cushion break down, during as phenomenons such as gas leakage, seizure of pistons, need first from fuselage workbench top, air cushion top board 35, support pad 36 once to be split out, again remaining part is split out in the lump from under-chassis, due to limited space, operating difficulties;
2), owing to lacking effectively guiding, when piston 38 is when the interior motion of cylinder block 39 has some setbacks or bears unbalance loading, easily pull cylinder surface or fine and close sealing and damage and leak gas.
3) the machine worktable fit beneath spatial limitation that is stressed, the design of die-cushion ability is limited.
4) air cushion top board 35 and the direct contact impact of thimble, easily distortion causes that pressure-pad-force is inhomogeneous even cannot be used, once there is this situation, just need to change the air cushion top board 35 that monoblock is new, causes unnecessary waste;
5) die-cushion is when work, and stampings or other foreign matters are easily fallen into die-cushion inside, cause cylinder body to pull and even damage seal, lead machine processed and cannot normally use.
Therefore, be necessary further improvement.
