Description
Technical field
The present invention relates to taper roller upsetter, it belongs to bearing machining apparatus field.
Background technology
U.S. BH series steel ball Balance mechanism, production efficiency is high, is the product of the advanced level eighties.It has high, the fireballing feature of precision, is quite subject to user's welcome.BH-201 steel ball Balance mechanism consists of mechanical system, electric-control system, pneumatic system, lubricating system and feed system, alignment system, adopts single station header system.The band wheel drive that is 3 by a pair of gearratio by 55 kilowatt motors, drives main shaft, cam, bevel gear and connecting rod control and completes cut-out, Switch of working position and the upsetting of blank, a section frequency 300 times/per minute.BH-201 steel ball Balance mechanism requires also high to material material, due to domestic technique level and market reasons, this utilization rate of equipment and installations is extremely low.
Summary of the invention
In view of the defect that prior art exists, the present invention carries out functional transformation to Balance mechanism, and taper roller upsetter is provided, for processing taper roller.Make idle equipment performance usefulness, can solve again the production and processing problem of taper roller.
For achieving the above object, the technical solution adopted in the present invention is: taper roller upsetter, comprise main motor, ram, upper punch pedestal, low punch pedestal, on upper punch pedestal, upper punch is set, on low punch pedestal, low punch is set, main motor is connected with ram by connecting rod, and upper punch connects firmly on ram, also comprise out jaw mechanism, open jaw mechanism by seat board, skewback, roller, pincers finger pressure wheel, lever, fixed pincers refer to, moving pincers refer to, spacing jackscrew, spring form; Seat board connects firmly on upper punch pedestal and low punch pedestal, on seat board, arrange determine pincers refer to and move pincers refer to, moving pincers refer to connect firmly pincers finger pressure wheel, lever is set on seat board, one end of lever acts on pincers finger pressure wheel above, and the other end connects firmly roller, and the fulcrum of lever arranges spacing jackscrew, spring, upper punch is solid skewback, skewback ramp effect roller; Upper punch is close to low punch, and when skewback moves to roller and reaches its inclined-plane peak, roller jack-up lever connects firmly one end of roller, makes to clamp to refer to throw off blank by pressing tongs finger pressure wheel under lever; After upper punch is recalled, solid skewback on upper punch is also recalled, under the effect of spring, under lever, the constraint of spacing jackscrew is lifted and be subject in one end of pressing tongs finger pressure wheel, and the assignment of moving pincers is closed and determined pincers and refer to clamp blank 12.Described main motor is frequency control motor.
Adopt after such scheme, compared with prior art there is following beneficial effect: it is top bed die material folding moment that BH-201 steel ball Balance mechanism pincers refer to throw off, utilize self to withdraw power and extract from blank, for steel ball, this mode on punching press after element precision there is no impact.But punching press taper roller, when blank is referred to that by pincers clamping, just in upper/lower die material folding moment, if any a Lateral Force, will affect the stability of blank between mould, causes part punching precision to reduce, and even occurs waste product.In addition, taper roller diel structurally there are differences compared with steel ball diel, is also not suitable for the existence of this power.For this problem, manufactured and designed and opened jaw mechanism, increase mechanical interlocking and open pincers power and introduce, make out together with pincers actions organically contacted with main motion.Guarantee that at upper/lower die, just contacting blank moment drives pincers, to guarantee that pincers refer to continue the function of righting, the rate of reducing the number of rejects and seconds.
Accompanying drawing explanation
Fig. 1 is the front view that taper roller upsetter is opened jaw mechanism;
Fig. 2 is the side view that cone roller upsetter is opened jaw mechanism.
In figure: 1, seat board, 2, skewback, 3, upper punch, 4, roller, 5, low punch, 6, pincers finger pressure wheel, 7, lever, 8, fixed pincers refer to, 9, moving pincers refer to, 10, spacing jackscrew, 11, spring, 12, blank, 13, low punch pedestal, 14, upper punch pedestal, 15, ram.
The specific embodiment
For understanding the structure of taper roller upsetter in depth, in conjunction with Fig. 1 and Fig. 2, be described as follows:
Taper roller upsetter, comprise main motor, ram 15, upper punch pedestal 14, low punch pedestal 13, upper punch 3 is set on upper punch pedestal 14, low punch 5 is set on low punch pedestal 13, main motor is connected with ram 15 by connecting rod, upper punch 3 connects firmly on ram 15, and main motor is frequency control motor.Taper roller upsetter upsetting station comprises out jaw mechanism, open jaw mechanism by seat board 1, skewback 2, roller 4, pincers finger pressure wheel 6, lever 7, fixed pincers refer to 8, moving pincers refer to 9, spacing jackscrew 10, spring 11 form; Seat board 1 connects firmly on upper punch pedestal 14 and low punch pedestal 13, on seat board 1, arrange determine pincers refer to 8 and moving pincers refer to 9, moving pincers refer to that on 9, connecting firmly pincers finger pressure takes turns 6, lever 7 is set on seat board 1, one end of lever 7 acts on pincers finger pressure wheel 6, and the other end connects firmly roller 4, and the fulcrum of lever 7 arranges spacing jackscrew 10, spring 11, upper punch 3 is solid skewback 2, skewback 2 ramp effect rollers 4; Upper punch 3 is close to low punch 5, and when skewback 2 moves to roller 4 and reaches its inclined-plane peak, roller 4 jack-up levers 7 connect firmly one end of roller 4, make to clamp to refer to 9 disengagement blanks 12 by 7 times pressing tongs finger pressures wheels 6 of lever; After upper punch 3 is recalled, solid skewback 2 on upper punch 3 is also recalled, under the effect of spring 11, one end of 7 times pressing tongs finger pressures wheels 6 of lever lifts and is subject to the constraint of spacing jackscrew 10, moving pincers to refer to that 9 cooperations clamp surely to refer to 8 clamping blanks 12.
BH-201 steel ball Balance mechanism consists of mechanical system, electric-control system, pneumatic system, lubricating system and feed system, alignment system, adopt single station header system, the band wheel drive that is 3 by a pair of gearratio by 55 kilowatt motors, drive main shaft, cam, bevel gear and connecting rod control and complete cut-out, Switch of working position and the upsetting of blank, a section frequency 300 times/per minute.The present invention, take BH-201 steel ball Balance mechanism as basis, has increased and has opened jaw mechanism at the upsetting position of mechanical system, guarantees that at upper punch mould and low punch mould, just contacting blank moment drives pincers, to guarantee that pincers refer to continue the function of righting, the rate of reducing the number of rejects and seconds.In conjunction with taper roller punching press feature, manufactured and designed blank mould, diel, pay-off and corresponding servicing unit, repeatedly adjust, Improvement and perfection.
The processing beat of BH-201 steel ball Balance mechanism is to be determined by the rotating speed of main drive motor, and main drive motor originally can not speed governing, and productive temp is fixed on about 240/minute.Due to the requirement of product and technique, the processing mode of originally fixing beat can not meet need of production, therefore main transmission section has been carried out to freguency control reform.From the viewpoint of speed adjustable range and adjusting speed accuracy, employing has the vector control mode of velocity sensor by the Automatic parameter recognition function of frequency converter, in the debug phase, obtain the relevant parameters of motor, guarantee, on speed adjustable range and adjusting speed accuracy, to meet technological requirement.
Taper roller upsetter adds out pincers function, and employing dish circle material processing roller, by frequency control, realizes the adjustment of the upsetting frequency, guarantees equipment reliability of operation, stability and security.Adjusting range can be set arbitrarily between 100 beats/min ~ 250 beats/min.Roller formed precision meets Product Process requirement, and punching press axiality is less than 0.10mm, and roller length allowance control, in 0.20mm, has reduced punching press percent defective.
