Integral hanging formula mould tapping device
Technical field
The present invention relates to a kind of tapping device, relate to a kind of integral hanging formula mould tapping device specifically.
Background technology
Mould tapping device is again mould internal tapping device, is to coordinate with five metals continuous mould, carries out the equipment of screw hole processing in hardware punch process fast simultaneously.
Mould tapping device is by traditional " punching press " and " tapping " technology " integration " straight forming in mould together.What mould tapping device adopted is thread forming tap tapping, so can not produce the chip formed because of cutting in thread forming process, accomplished clean environment firendly, and the intensity of screw thread obtains good raising.These are all that traditional handicraft machining can not be compared.Because mould tapping machine has above-mentioned feature, so mould tapping machine is widely used.
Traditional mould tapping machine, for fixed design, its mould tapping apparatus main body is arranged on lower mould plate or stripper specifically, drive screw partial fixing is at cope match-plate pattern, in certain punching stroke space, under the extruding moved downward by slider of punch, screw tap downward movement also rotates and carries out tapping processing to material, and then at slider of punch, up rollback drive screw tap is anti-toward moving and counter-rotating, in tooth hole, return reset, complete whole tapping process.
Traditional mould tooth machining unit, because install and working method restriction, its institute is dynamic all from punch press, it can only be fixed connection design, occupy punching stroke space greatly, make feeding space less, during as adopted traditional manual feeding operation, feeding discharging can't be affected, but as adopted mechanical automation feeding style, when using repeatedly first feeding mechanical hand, it brings great inconvenience to the feeding of automatic feeder structure, and be fixed on mould tapping machine in punching stroke easily and automatic feeder structure or material itself touches, affect tapping mechanism normally to work.
Summary of the invention
The object of the present invention is to provide one to be applicable to coordinate with automatic feeder structure, together can move up and down with punching press thus maximize the integral hanging formula mould inside fire attack device ensureing feeding space.
To achieve these goals, the present invention is achieved by following technological means.
Integral hanging formula mould tapping device of the present invention, includes upper padding plate, lower bolster, drive screw, Drive Cup department, tapping mechanism and transmission mechanism.
Upper padding plate is also installed with a drive screw.
Many springs are also connected and installed with between described upper padding plate and lower bolster.
Preferred as one, described spring is nitrogen spring.
Lower bolster lower surface is arranged many positioning guide column.
Lower bolster is also rotatablely equipped with the Drive Cup department with described drive screw corresponding matching.
In described Drive Cup department, cover has driving gear.
Tapping mechanism is fixedly mounted on lower bolster.
Described tapping mechanism includes housing, screw tap, float plate, driven gear and screw mandrel.
Described driven gear is fixedly mounted in described housing, and can rotate freely along its axle center.
Described driven gear axle center hole inwall is provided with screw thread.
Screw tap afterbody and one inserts screw mandrel in driven gear axle center hole and is connected and coordinates.
Described float plate is arranged on housing lower surface, to be connected to coordinate by the guide pillar that is provided with spring with housing.
Described float plate is provided with and corresponding with screw tap position goes out taper hole.
Described driving gear is coordinated by the transmission mechanism transmission be arranged on lower bolster with between driven gear.
Described transmission mechanism is made up of multiple pitch wheel.
During work of the present invention, it is fixed on the upper mould seat that is arranged on punch press by entirety, to be transferred by staff for coordinating stamping products or other automatic feeder structure moves the thread forming sending row product to, upper bolster is descending in the drive of punching apparatus, move to lower bolster when contacting with the lower supporting plate on lower pressing equipment workbench, start compressed nitrogen spring, and promote drive screw, Drive Cup department converts the rotary motion of Drive Cup department to the vertical lower action of drive screw, driving gear in Drive Cup department and Drive Cup department synchronous rotary, driven gear is driven to rotate by transmission mechanism, rotated by driven gear again and change via screw mandrel, drive the rotation of screw tap and move up and down.When upper bolster comes downwards to minimum point, tapping action completes, and starts to reset, and the nitrogen spring in the present invention resets, and promotes lower bolster reseting movement, Drive Cup department is reversed, thus drives screw tap to reversely rotate and rollback, realizes moving back agomphiasis and does.
The present invention is compared with conventional art, and its good effect is, tapping device and punching apparatus synchronously move up and down, and time to be processed, are reserved with larger stroke space to automatic feeder structure, facilitate automated production to process.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is done into a description.
In the drawings, upper padding plate 1 is also installed with a drive screw 3.
Many nitrogen springs 5 are also connected and installed with between described upper padding plate 1 and lower bolster 2.
Lower bolster 2 lower surface arranges many positioning guide column 13.
Lower bolster 2 is also rotatablely equipped with the Drive Cup department 4 with described drive screw 3 corresponding matching.
In described Drive Cup department 4, cover has driving gear 6.
Tapping mechanism 7 is fixedly mounted on lower bolster 2.
Described tapping mechanism 7 includes housing 8, screw tap 9, float plate 10, driven gear 11 and screw mandrel 12.
Described driven gear 11 is fixedly mounted in described housing 8, and can rotate freely along its axle center.
Described driven gear shaft 11 central hole inwall is provided with screw thread.
Screw tap 9 afterbody and one inserts screw mandrel 12 in driven gear 11 axle center hole and is connected and coordinates.
Described float plate 10 is arranged on housing 8 lower surface, to be connected to coordinate by the guide pillar that is provided with spring with housing 8.
Described float plate 10 is provided with and corresponding with screw tap 9 position goes out taper hole.
