Abstract
The invention discloses a method for keeping static tapping for a stamping die inside a tapping machine, comprising the following steps: the die inside tapping machine is fixedly installed on a buoyancy lifting plate arranged between an upper template and a lower template, a buoyancy lifting pin is arranged on the lower template, and a stripper plate is installed on the upper template. When a stamping die moves downwards to stamp a part, the buoyancy lifting plate is propped up by a jacking spring, the stripper plate on the upper template presses down the buoyancy lifting pin downwards and presses down the buoyancy lifting plate at the same time, workpieces are arranged on the buoyancy lifting pin and the buoyancy lifting plate, and the die inside the tapping machine is also arranged on the buoyancy lifting plate, thereby ensuring that the stamping workpieces and a screw tap are all in a relatively static state during tapping. Threads are formed according to a track of 12 screw pitch rotation of a screw tap, therefore, the phenomena that the stamping workpieces pull the screw tap to damage the threads in a threaded hole can not be generated, and the problem of thread damage duringthe tapping is completely solved. By adopting the method, the tapping quality is ensured, processing of a fine pitch threaded hole with a screw pitch of 0.25 mm is also realized, and the processing range is expanded.
Description
Technical field
The invention belongs to pressing equipment manufacturing technology field, relate in the punch process process mounting means of tapping machine in the mould, be specifically related to a kind of method that tapping organizational security in the diel mould is held static tapping that is used for.
Background technology
In the prior art, the tapping machine is to be contained in a kind of in the diel mould to be moved up and down thereby converting to rotatablely moves carries out the device of screw tapping in the known mould, when carrying out workpiece punching press and screw tapping, because punching press and tapping are carried out simultaneously, for tabular, the stamped workpieces of strip material exists bend tension and buoyance lift to move big phenomenon, material can produce in the process of conveying and punching press and move up and down, at this moment, the cutting movement track of the screw tap in the mould on the tapping machine can not be consistent with the screw hole helical pitch, need spur screw tap motion compensation pitch difference with material, go processing screw hole and screw tap with the pulling force band of this material, tend to damage the screw thread in the screw, especially can't process less than the closely-pitched screw of 0.4mm pitch at all, bring difficulty for the manufacturing processing of product.
Summary of the invention
The purpose of this invention is to provide a kind of method that the interior tapping organizational security of diel mould is held static tapping that is used for, solved the problems referred to above that the tapping machine exists in the existing press machine mould.
The technical solution adopted in the present invention is, a kind ofly be used for the method that tapping organizational security in the diel mould is held static tapping, this method is that the tapping machine is fixedly mounted on the buoyance lift plate of below setting in the mould that will be arranged between cope match-plate pattern and the lower bolster, the reverse side of buoyance lift plate is equipped with support bar, the support bar lower end is loaded in the guide holder that lower bolster is provided with, and be supported on lower bolster pop-up floating lift slab by the jacking spring that is enclosed within on the support bar, the buoyance lift pin also is housed on lower bolster, stripper plate also is housed on cope match-plate pattern.
Of the present inventionly be used for the method that tapping organizational security in the diel mould is held static tapping, its feature also is,
Spring is equipped with in described buoyance lift pin below, together moves up and down with the buoyance lift plate that tapping machine in the mould is installed.
The present invention is used for the method that the interior tapping organizational security of diel mould is held static tapping, tapping machine fixed installation in the mould is arranged on the buoyance lift plate that is provided with between cope match-plate pattern and the lower bolster, and is provided with the buoyance lift pin on lower bolster, and stripper plate is housed on cope match-plate pattern.When diel moves downward punching parts, the buoyance lift plate is held up by the jacking spring, the stripper plate of cope match-plate pattern is depressed the buoyance lift pin downwards, depress the buoyance lift plate simultaneously, workpiece is on buoyance lift pin and buoyance lift plate, the tapping machine is also on the buoyance lift plate in the mould, stamped workpieces was in relative inactive state when this had just guaranteed tapping, screw thread is according to the track moulding of screw tap pitch rotation, therefore can not produce the phenomenon of being damaged the screw thread in the screw by stamped workpieces pulling screw tap tapping, the problem of screw thread damage when having solved tapping, when having guaranteed tapping quality, it is feasible that the closely-pitched screw that carries out 0.25mm pitch is processed into, and enlarged the range of work, improved machining accuracy.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
A kind ofly be used for the method that tapping organizational security in the diel mould is held static tapping, as shown in figures 1 and 3, this method is that tapping machine 3 is fixedly mounted on the buoyance lift plate 4 of below setting in the mould that will be arranged between cope match-plate pattern 1 and the lower bolster 2, the reverse side of buoyance lift plate 4 is equipped with support bar 5, support bar 5 lower ends are loaded in the guide holder 6 that lower bolster 2 is provided with, and be supported on lower bolster 2 pop-up floating lift slabs 4 by the jacking spring 7 that is enclosed within on the support bar 5, buoyance lift pin 8 also is housed on lower bolster 2, stripper plate 9 also is housed on cope match-plate pattern 1, and spring 10 is equipped with in described buoyance lift pin 8 belows.
The present invention is used for the method that the interior tapping organizational security of diel mould is held static tapping, be to realize like this when carrying out stamped workpieces and tapping, as shown in Figure 2,3 fixed installations of tapping machine in the mould are arranged on the buoyance lift plate 4 that is provided with between cope match-plate pattern 1 and the lower bolster 2, and on lower bolster 2, be provided with buoyance lift pin 8, stripper plate 9 also is housed on the cope match-plate pattern 1, when diel moves downward stamped workpieces 11, buoyance lift plate 4 is held up by jacking spring 7, the stripper plate 9 of cope match-plate pattern 1 is depressed buoyance lift pin 8 downwards, depress buoyance lift plate 4 simultaneously, workpiece 11 is on buoyance lift pin 8 and buoyance lift plate 4, tapping machine 3 is also on buoyance lift plate 4 in the mould, stamped workpieces is in relative inactive state when having guaranteed tapping, when carrying out workpiece 10 punching presses, the nut that the drive of the screw rod pressurized of tapping machine 3 is mated in the mould rotates and drives screw taps 12 rotations by the gear trains in the tapping machine in the mould 3 and carries out tapping, because buoyance lift plate 4 is with 8 motions of buoyance lift pin, stripper plate 9 is depressed buoyance lift pin 8 and is pushed down stamped workpieces 11 on buoyance lift plate 4, the screw tap 12 workpiece 11 strip material pulling that is stamped when having limited in the mould 3 tappings of tapping machine, stamped workpieces 11 is in relative inactive state when having guaranteed tapping, screw thread is according to the track moulding of screw tap 12 pitch rotations, thereby can not produce the phenomenon of damaging the screw thread in the screw by stamped workpieces 11 pulling screw tap 12 tappings, and adopt the method for this static tapping, not only guaranteed tapping quality, also make the closely-pitched screw that carries out 0.25mm pitch be processed into feasible, enlarge the range of work, improved machining accuracy.
