Forcing press
Technical field
The utility model relates to a kind of half-closed or straight side press, relates in particular to for improvement half-closed or the straight side press Lifting Device.
Background technology
The Lifting Device of existing half-closed forcing press and straight side press, knockout rod length surpasses fuselage width, and stretch out outside the fuselage at two ends, and the dnockout rod also must correspondingly be placed in fuselage outer side.Shown in Fig. 3,4, for satisfying the demand of feeding and dnockout rod, feeding window 12 need be increased, strengthen, and has influenced the intensity and the rigidity of fuselage.
Summary of the invention
The utility model provides a kind of and has satisfied under the prerequisite of liftout at above problem, and the intensity and the rigidity that can improve fuselage reduce, and easy to operate forcing press.
The technical solution of the utility model is: comprise fuselage, be positioned at the slide block and the Lifting Device of fuselage, described Lifting Device comprises dnockout rod, push rod, knockout rod and mount pad, be respectively equipped with the feeding window on the fuselage biside plate, the length of described dnockout rod is less than the width between described fuselage biside plate, and described knockout rod is connected in the inboard of fuselage biside plate by mount pad.
Described mount pad comprises thread, pedestal, attachment screw and locking nut; Described pedestal runs through the fuselage side plate, and pedestal is provided with a horizontal through hole, and described thread can be located in the described horizontal through hole axially and movably; End in fuselage is respectively equipped with the radial direction through hole that is used for ccontaining described knockout rod at pedestal and thread; The other end of thread is established screw thread, and stretches out pedestal, and described locking nut links to each other with the screw thread of the described thread other end; Described pedestal is provided with connecting hole, and described attachment screw is connected in pedestal on the fuselage side plate from the fuselage side plate outside.
The utility model has changed traditional habit of the prior art, shortens dnockout rod length, and Lifting Device integral body is located at fuselage interior, thereby has avoided offering on the fuselage side plate defective of fuselage intensity that bigger window brings and rigidity reduction.When the dnockout rod is located at rear flank in the fuselage, brought knockout rod also to need to be arranged on the problem of fuselage inboard thereupon, and the knockout rod mount pad is located at the words of fuselage inboard, can bring operation, regulate inconvenience, for this reason, the utility model has also proposed the supplementary technology scheme of mount pad, and it can make knockout rod be positioned at the fuselage inboard, regulates, locking operation then can finish at fuselage outer side.The utility model exquisite composition has overcome the big window of key position setting at fuselage, thereby reduces the problem of fuselage intensity and rigidity.

The specific embodiment
The utility model as shown in Figure 1, 2, comprise fuselage 8, be positioned at the slide block 6 and the Lifting Device of fuselage 8, described Lifting Device comprises dnockout rod 11, push rod 10, knockout rod 2 and mount pad 4, be respectively equipped with feeding window 9 on the biside plate of fuselage 8, the length of described dnockout rod 11 is less than the width between described fuselage 8 biside plates, and described knockout rod 2 is connected in the inboard of fuselage 8 biside plates by mount pad 4.
Described mount pad 4 comprises thread 5, pedestal 1, attachment screw 7 and locking nut 3; Described pedestal 1 runs through the side plate of fuselage 8, and pedestal 1 is provided with a horizontal through hole, and described thread 5 can be located in the described horizontal through hole axially and movably; End in fuselage 8 is respectively equipped with the radial direction through hole that is used for ccontaining described knockout rod 2 at pedestal 1 and thread 5; The other end of thread 5 is established screw thread, and stretches out pedestal 1, and described locking nut 3 links to each other with the screw thread of described thread 5 other ends; Described pedestal 1 is provided with connecting hole, and described attachment screw 7 is connected in pedestal 1 on fuselage 8 side plates from the fuselage 8 side plates outside.
The course of work of the present utility model is: when slide block 6 moves downward, because the effect of workpiece by the push rod in the mould 10, rises dnockout rod 11 in slide block 6.Knockout rod 2 is fixed by thread 5, pad, locking nut 3 and pedestal 1, when thread 5 moves laterally, knockout rod 2 is formed with shear-type load, realizes axial restraint.When slide block 6 backhauls make progress near top dead-centre, dnockout rod 1 contacts with knockout rod 2, because it is motionless that the pedestal 1 of mount pad 4 is fixed on fuselage by attachment screw 7 (soket head cap screw), dnockout excellent 11 is motionless so slide block 6 continues to rise, and by the push rod in the patrix 10 workpiece is ejected.At fuselage outer side, unclamp clamp nut 3, can adjust the height of knockout rod 2, easy to adjust, and feeding window 9 need not to increase, strengthen, and the intensity and the rigidity of fuselage 8 are strengthened.
