Abstract

The utility model relates to an automatic article taking-out punch with a slipping lower die holder, which is composed of a machine body, a machine frame, a slip block for fixing an upper die, a slipping lower die holders for fixing a lower die, a lower support holder, and a cylinder (oil cylinder), etc., wherein, a hollow cavity is arranged on the slip block, a magnetic conducting device composed of a coil, an iron core, and a non-magnetic conducting upper die holder is arranged in the hollow cavity. The upper die can suck a workpiece through the magnetic force of the iron core, and meanwhile, a support plate for bearing the workpiece is arranged on the lower die holder. Because the lower die holder of the utility model can slip out of the slide block, the utility model has safe and labor-saving material discharge, and meanwhile, the utility model can also accomplish an automatic article taking-out function. The utility model has the advantages of reasonable structural design, safety and reliability, is applied to various punches with cold-press formation, can also be used for correction beds for correcting castings and forgings.

Description

The automatic part picking forcing press of band slidingtype die shoe

The automatic part picking forcing press of the band slidingtype die shoe that a kind of cold moudling or calibration metal parts are used.

This structure belongs to and the forcing press class of suppressing relevant band servicing unit.

Existing cold moudling or the various forcing presses used of calibration metal parts are proofreaied and correct bed, by fuselage, frame, the fixedly slide block and the fixing compositions such as support of counterdie of patrix.During operation, the operative employee puts into compression moulding on the counterdie with workpiece, leans on instrument then or manually takes off workpiece.This method of operating needs staff to stretch into slide block and transfers part, pickup, and time-consuming, effort is dangerous again.For addressing this problem, a kind of forcing press with the slidingtype die shoe appearred, and its structure is that support is provided with slideway, die shoe is contained on the slideway, drags by cylinder (or oil cylinder), slides along horizontal plane, and counterdie can shift out under the slide block puts part, pickup.Therefore safe, laborsaving.But pickup must be leaned on manual operation, and operating efficiency is lower.

It is a kind of promptly safe, laborsaving that the utility model provides, and can improve work efficiency again, and reliable operation is rational in infrastructure, can realize the forcing press of the band slidingtype die shoe of automatic part picking.

The forcing press of this structure, by air cylinder driven die shoe is moved along the V-type inclined-plane, patrix is by the magnetic force pickup, die shoe is adorned a supporting plate of accepting workpiece, frame is provided with a cover auxiliary reset mechanism, guarantee that upper and lower die worker does synchronously, patrix pressurization simultaneously and pickup are once finished, thereby realize fast automatic pickup.

The design's concrete structure and operation principle are described in detail in conjunction with the following drawings.

The front view of Fig. 1, forcing press

The side view of Fig. 2, forcing press

The A-A profile of Fig. 3, front view

This structure is by fuselage (summary), frame 16, fixedly slide block 2 and the fixedly die shoe 9 of counterdie 8 and undersetting 17, cylinder 21(or the oil cylinder of band chute 18 of patrix 6) etc. form.Wherein have cavity 3 in the slide block 2, the magnetic conduction device of being made up of the upper bolster 5 of hot-wire coil 4 and iron core 1 and non-magnet material is housed in the chamber, patrix 6 picks up workpiece by the magnetic force of iron core 1, and the afterbody of die shoe 9 is equipped with the supporting plate 11 of accepting workpiece simultaneously.Coil 4 energisings are by travel switch 24 controls that are contained on the slide block 2.And two stroke link stoppers 25,22 up and down are housed on the frame 16, and travel switch 24 moves between two link stoppers 25,22 with slide block 2.And V-shaped of described die shoe 9 its bottoms, also corresponding V-shaped of the slide groove 18 of undersetting 17.Extend along the V-type inclined-plane and stretch out slide block 2 one section outer slide groove 18, die shoe 9 is moved along the inclined-plane, and lean on it to reset from the gravity downslide, for making compact conformation, the bottom of die shoe 9 has groove 12, and cylinder 21 is arranged in the groove 12, and is fixed on the undersetting 17, the piston rod 10 of cylinder 21 links to each other with die shoe 9, and die shoe 9 is with piston rod 10 motions.Roller can be adorned in die shoe 9 bottoms simultaneously, also can adopt slide rail.The design will adopt the roller type die shoe to prevent that putty from polluting, slide groove 18 blocks.Be that die shoe 9 bottoms two opposite side respectively have groove 29, be provided with underframe 20 in the groove, die shoe 9 wears spring 30 by screw 31 and links to each other with underframe 20, and roller 19 is contained on the underframe 20.The slide groove 18 of the bottom surface of die shoe 9 and undersetting 17 maintains some gaps when no pressure, when slide block was depressed, the impulsive force of die shoe 9 was born by undersetting 17 entirely, and the roller 19 then effect lower stress at spring 30 is very little.

For slide block 2 work that make slidingtype die shoe 9 and fixing patrix 6 synchronously.The design is equipped with tooth bar 26 on slide block 2, the gear 28 that mates with tooth bar 26 is housed on the frame 16, and the transmission mechanism of gear 28 by being made up of power transmission shaft 7 and bevel gear 27 links to each other with plate wheel 13, be wound with steel wire 14 on the plate wheel 13, and an end of steel wire 14 is connected on the die shoe 9.When slide block 2 descended, gear 28 drove plate wheel 13 and rotates, and steel wire 14 is rolled.Die shoe 9 has guaranteed the reliability that resets by the accurate return of pulling force of steel wire 14.Simultaneously can a buffer gear 15 be housed, collide in order to avoid die shoe 9 produces when resetting in the junction of steel wire 14 and die shoe 9.

The course of work of this structure:

A, machine start are opened source of the gas.Slide block 2 rises, and cylinder 21 is pushed out to the uk position with die shoe 9, puts workpiece 23; Slide block 2 descends, and counterdie 9 is by cylinder 21 venting, accurately resets from the pulling force of gravity and steel wire 14, is in the OK position.Slide block 2 stamped workpieces, the travel switch 24 on it touches down link stopper 22, makes coil 4 energisings, and patrix 6 produces magnetic force by iron core, and workpiece 23 is picked up.

B, slide block 2 rise, and die shoe 9 shifts out, and supporting plate 11 enters slide block 2 times, and when slide block 2 rose to the uk position, travel switch 24 touched link stopper 25, coil 4 outages, and patrix 6 magnetic force disappear, and workpiece 23 falls into supporting plate 11 and derives.

The preferred plan of this structure as mentioned above.

The utlity model has reliable operation, to put part safe, laborsaving, reduces labour intensity, the advantage such as increase work efficiency, and can finish automatic pickup function is applicable to the forcing press of various cold moudlings and proofreaies and correct the correction bed of forging, foundry goods.
