Besides, said invention also provides the working principle of said upper-mounted shock absorber and its concrete operation method.
Description
Technical field
The invention belongs to the safety means of stamping machine, refer to a kind of punching press buffer unit of stamping machine especially.
Background technology
Present common hydraulic pressure stamping machine, generally be patrix to be installed in its slide block bottom surface, counterdie is installed at the work top middle part, the work top both sides are provided with 2 or 4 cushion cylinders, the master cylinder promotion slide block that is installed in during work on the frame upper beam is descending fast, when the patrix of slide block bottom surface during near the counterdie on the work top, slide block at first collides the cushion cylinder piston and slows down descending, arrive the cushion cylinder bottom until compression piston, master cylinder drives slide block and gos up, the punch forming or finish shearing in mould of upper and lower mould this moment complete matched moulds just in time, workpiece.Owing to be provided with above-mentioned buffer unit, make punching production steadily and safety, the impact that has alleviated equipment and mold greatly is impaired and prolonged service life.Yet because the cushion cylinder of existing stamping machine all is arranged on the both sides of work top, therefore processing materials, workpiece can only pass in and out before and after the platen top, and can not about turnover, this has just limited the processing of the workpiece that many need pass in and out from about the lathe.
Summary of the invention
Purpose of the present invention is that technological improvement is carried out in the setting of the buffer unit of existing stamping machine, thereby provides a kind of workpiece that can adapt to carry out the stamping machine overhead buffer unit that the two-way turnover in all around is moved at workbench.
The technical solution that realizes above-mentioned purpose is: cushion cylinder is installed on the stamping machine upper beam goes up in-plane, the top of cushion cylinder is passed down through upper beam and slide block and fixes an equalizer bar with the pull bar rest that slide block is connected and fixed by two or four, the equalizer bar middle part offers the hole at cushion cylinder, the bottom of this hole is fixed with the feed screw nut, dispose the screw mandrel of band center slotted eye among the feed screw nut, the suitable for reading of equalizer bar hole covers with flange, and the lead screw transmission mechanism of being made up of motor and reducing gear is installed on flange, the square hole that the square shaft of socket is passed down through in flange and the screw mandrel upper port capping flange on the hollow output shaft of lead screw transmission mechanism inserts in the slotted eye of screw mandrel center.
The invention has the beneficial effects as follows: its effect of this overhead buffer unit is equal to the former buffer unit that is arranged on the workbench fully, but it does not take the workbench space, make processing materials and workpiece can be arbitrarily from space, all around turnover of workbench top, thereby make the punching press functional adaptation process workpiece widely, and its handling safety, reliable, convenient.

The specific embodiment
The invention will be further described with embodiment below in conjunction with accompanying drawing.
This machine comprises workbench 9 and four guide upright posts 3 that connected thereof, four guide upright post 3 upper ends are equipped with puts the beams in place 1,1 below of putting the beams in place is equipped with the slide block 4 that is driven by the piston that is arranged on the master cylinder 2 on the upper beam, slide block 4 bottom surfaces are equipped with patrix 5 and are positioned at the flanging oil cylinder 6 of its both sides, and Plane Installation has the counterdie 8 that matches with the patrix 5 of slide block bottom surface on the workbench 9.The cushion cylinder 10 of this machine is installed on the middle part on plane on the stamping machine upper beam 1, the top of cushion cylinder is passed down through by four and puts the beams in place 1 and the tie rod hole 26 of slide block and the pull bar 11 that is connected and fixed with slide block 4 and rest is fixed an equalizer bar 12, equalizer bar 12 middle parts offer the hole 24 at cushion cylinder, the bottom of this hole 24 is fixed with feed screw nut 14, dispose the screw mandrel 15 of band center slotted eye 27 among the feed screw nut 14, the upper oral part mounting flange 23 of equalizer bar hole 24 covers, and the lead screw transmission mechanism 13 that installation is made up of motor 21 and reducing gear 22 on flange 23, the output shaft 18 of lead screw transmission mechanism 13 is a hollow shaft, square shaft 16 upper ends are socketed on the hollow output shaft 18, and the square hole that the lower end is passed in flange 23 and the screw mandrel upper port capping flange 25 inserts in the screw mandrel center slotted eye 27.
Before the present invention starts working, need the buffer stroke of buffer unit is regulated.It is slowly descending to handle master cylinder 2 no pressure ground promotion slide block 4 earlier, stop during to patrix 5 and counterdie 8 matched moulds, start lead screw transmission mechanism 13 this moment, making its square shaft 16 drive screw mandrel 15 rotations descends until the piston that touches cushion cylinder 10, oppositely start lead screw transmission mechanism 13 then, make screw mandrel 15 return the distance of 0.7 δ (δ is a workpiece thickness), i.e. adjusting finishes.When beginning to produce, earlier workpiece 7 is positioned on the counterdie 8, it is descending fast to start master cylinder 2 promotion slide blocks 4, the flanging oil cylinder 6 of slide block bottom surface contacts and pushes down workpiece 7 earlier, then patrix 5 contact workpieces 7 and produce punching press or shear action, when slide block 4 continue descending 0.7 δ apart from the time, screw mandrel 15 begins to hit the piston of pressing cushion cylinder 10, thereby slowed down the downstream rate of slide block 4, up to screw mandrel 15 piston of cushion cylinder 10 is pressed onto the end, slide block 4 promptly stops descending and gos up, just in time punch forming or finish shearing of workpiece 7.When the thickness δ of a collection of workpiece changed, its buffer stroke need be regulated again.Present embodiment also is connected with rotary encoder 20 in output shaft 18 upper ends of lead screw transmission mechanism 13 by coupler 19, the operation of the buffer stroke of so just being more convenient at a distance, accurately regulating.In addition, also on equalizer bar hole upper port flange 23, the travel switch 17 that matches with screw mandrel 15 upper ends is installed, to limit the extreme higher position that screw mandrel 15 rises.
