Abstract
A novel in-mold tapping machine comprises an upper mold base, a lower mold base and a drive mechanism. The drive mechanism comprises a screw fixing support capable of moving along the vertical direction. A multi-thread screw and a multi-thread nut meshed with the multi-thread screw are arranged below the screw fixing support successively. The multi-thread nut is connected with a drive gear shaft through a keyway, a drive gear is arranged on the outside of the drive gear shaft, a transmission mechanism matched with the drive gear is arranged above a lower mold lifting plate, and the transmission mechanism is connected with screw taps. The upper mold base is driven to act and moves downwards to compress the screw fixing support to move downwards, the multi-thread screw moves downwards together to drive the drive gear shaft and the drive gear to rotate, and accordingly, gear sets of the transmission mechanism are driven to rotate, and the screw taps are driven to rotate to perform tapping downwards finally. According to the tapping machine, the drive mechanism and the transmission mechanism can be used repeatedly, the application range is wide, the cost is low, the stress on the lower mold lifting plate is uniform, the service life of the screw taps and the product yield are effectively increased, and the pressing efficiency is high.
Description
Technical field
The present invention relates to technical field of mold, relate in particular to a kind of mould internal tapping machine of realizing self-tapping in mould.
Background technology
Cold stamping handware is widely used in industrial production, while needing screw hole on some product, by tooth machining unit is installed in diel, carries out tapping, to enhance productivity, guarantees product quality.
Existing mould tapping machine, mainly by gear-box and screw rod two parts, formed, gear-box is arranged on concave template, when slider of punch is descending, screw rod promotes the nut rotation in gear-box downwards, thereby drive screw tap tapping on product, when slider of punch is up, screw rod upwards pulls the nut in gear-box to reverse, and finally drives screw tap to exit product.
Above-mentioned existing mould tapping machine has following shortcoming: 1, spiro rod length is long, and concave template and work bench of punch press will have enough spaces to dodge screw rod, usually need on work bench of punch press, bore and dodge hole, and inconvenience is installed; 2, a set of tooth machining unit can only be corresponding a kind of product of tapping, when product is not produced, this tooth machining unit is just scrapped, not reproducible utilization; 3,, after mould tapping machine has designed, the degree of depth that screw tap is shot product is just fixed and is unadjustable, there is no adjustability; Tapping hole burr and the problem such as no-go gage is logical, easily appear that screw tap is disconnected, in 4, counterdie buoyance lift plate discontinuity.
Summary of the invention
In view of this, the invention provides a kind of New-type mould internal tapping machine, long to solve prior art spiro rod length, the defect of tapping machine buoyance lift plate discontinuity.
The design that the present invention takes is:
A kind of New-type mould internal tapping machine, comprise the upper bolster being connected with punch press top shoe, be installed on the die shoe of work surface of punching machine and the counterdie buoyance lift plate of die shoe top, below upper module, be provided with briquetting, also comprise a driving mechanism, described driving mechanism comprises the screw rod fixed support that can vertically move up and down, screw rod fixed support below is provided with multiple-threaded screw, multiple-threaded screw below is provided with the bull nut with multiple-threaded screw screw-threaded engagement, bull nut is connected by keyway with gear shaft, gear shaft outside is provided with driven wheel, described counterdie buoyance lift plate top is provided with the transmission mechanism coordinating with driven wheel, described transmission mechanism connects screw tap, the action of driving upper bolster, upper bolster moves downward compressing screw rod fixed support and moves downward, and multiple-threaded screw together moves downward with threaded fixed support, drives gear shaft and driven wheel rotation, and then the rotation of the gear train in drive transmission mechanism, finally drive screw tap to rotate downward tapping.
Further, described transmission mechanism comprises the driving gear set one engaging with driven wheel, the driving gear set two engaging with driving gear set one.
Further, in described driving gear set two, tapper mechanism is installed, wire taper sleeve is installed in tapper mechanism, screw tap is fixed on wire taper sleeve lower end, wire taper sleeve be connected with driving gear set two and pass through its drive rotary work.
Further, described driving mechanism is provided with bull nut and the nut fixed support for driving mechanism being fixed on to die shoe.
Further, between described die shoe and counterdie buoyance lift plate, be provided with counterdie backing plate.
Further, described transmission mechanism is arranged on box house, and casing comprises lower of casing and box cover.
Compared with prior art, tool of the present invention has the following advantages:
The present invention is connected with transmission mechanism by multiple-threaded screw is set, and screw rod fixed support is set multiple-threaded screw is fixed on die holder, makes this tapping machine not be subject to the impact of punch press sliding stroke, and spiro rod length is not long again, makes the scope of application of this tooth machining unit wider; When the product of tapping different-diameter, only need to replace the screw tap of different model, its driving mechanism and transmission mechanism can reuse simultaneously, have reduced the cost of tapping; Because multiple-threaded screw can vertically slide up and down, screw thread engages with transmission mechanism again, and therefore the length of adjustable multiple head screw rod reaches the object that regulates the tap tapping degree of depth; Design quick change construction, facilitated this device dismounting; The fixed form that changes gear drive and drive unit, makes construction standard; Use single drive leader, multiple-threaded screw is driven while moving downward stressed even, the problems such as tapping hole burr and no-go gage are logical have been avoided, in addition, gear-box and tapping case are installed on slide rail, and slide rail is positioned at mould inside, thereby this tapping machine becomes an entirety with mould, are directly installed to punch press inside, mold attaching/detaching can not have influence on tapping machine, improves the operating efficiency of punching press.
