The utility model content
The purpose of this utility model is to overcome the defective that exists in prior art, a kind of mould tapping device is provided, can avoid secondary operations and the secondary of tapping product to locate, make diel accomplish that continuous punching completes, make product fast and effeciently once in mould punching press complete, improving production efficiency greatly.
for realizing above-mentioned technique effect, the technical solution of the utility model is: a kind of mould tapping device, it is characterized in that, described mould tapping device comprises upper bolster and die shoe, the lower end of described upper bolster is fixedly installed tapping mechanism, described tapping mechanism comprises casing, be vertically installed with tooth bar on described die shoe, the shrinkage pool of described casing one side coordinates with tooth bar and is slidably connected, be provided with head in described casing, be provided with the screw tap fixture in described head, described screw tap fixture is connected with the upper end of screw tap is detachable, also be provided with the transmission mechanism that matches with described tooth bar and screw tap fixture in described casing.
Can separate with stamping parts more smoothly after tapping is completed for the ease of screw tap, preferred technical scheme is, described mould tapping device also comprises the screw tap ejecting mechanism, described screw tap ejecting mechanism comprises the guide thimble that is parallel to described tooth bar, the upper end of described guide thimble is fixedly connected with described casing, be provided with spring in described guide thimble, the lower end of described spring is connected with knock pin, and the top of described knock pin is set in described guide thimble.
In order to simplify transmission mechanism, the convenient manufacturing, preferred technical scheme is, and described transmission mechanism comprises the worm gear that matches with described tooth bar, and the worm screw of described worm gear and screw tap fixture upper end is connected, and described worm screw is connected with described screw tap fixture.
More convenient when the screw tap ejecting mechanism is used, preferred technical scheme is that the top of described guide thimble and spring is fixedly installed in described casing by securing member.
For the ejecting force that guarantees screw tap ejecting mechanism when the tapping operation minimizes, preferred technical scheme is, under the spring load-less condition, the low side of described knock pin is higher than the end of described screw tap and lower than the low side of described screw tap fixture.
In order to keep the stress balance of twice of screw tap, preferred technical scheme is that described tooth bar and guide thimble are arranged on the both sides of described head.
In order to simplify the structure of mould tapping device, preferred technical scheme is that described screw tap fixture is tap holder.
Discharge during for the ease of the tapping of processing through hole, preferred technical scheme is to be provided with the material-dropping hole relative with described screw tap on described die shoe.
Occur laterally by a relatively large margin swing and vibration when upper bolster moves downward before the tapping, preferred technical scheme is that both sides, described upper bolster lower end are respectively arranged with the vertically-guided post.
Advantage of the present utility model and beneficial effect are: this mould tapping apparatus structure advantages of simple, use this device mate with threaded holes tapping can avoid secondary operations and secondary in tradition processing to locate, make diel accomplish that continuous punching completes, make product fast and effeciently once in mould punching press complete, improving production efficiency greatly.
