Description
Technical Field
The invention relates to an in-mold tapping machine, in particular to an improved integral tapping machine which is suitable for small or no stripping stroke, large product floating stroke and requirements on the in-mold space occupied by tapping.
Background
The in-mold tapping device is also called an in-mold tapping device, and is equipment which is matched with a hardware continuous die and can rapidly process screw holes during the stamping processing of hardware parts.
The in-mold tapping device integrates the traditional 'stamping' and 'tapping' technologies together to be directly formed in a mold. The in-mold tapping device adopts the extrusion tap for tapping, so that cutting scraps formed by cutting cannot be generated in the thread forming process, cleanness and environmental protection are achieved, and the strength of threads is well improved. These are incomparable with conventional processes. Because the in-mold tapping machine has the characteristics, the in-mold tapping machine is widely used.
Traditional mould tapping machine, because installation and working method are injectd, its all power all come from the punch press, it can only be the design for fixed connection, occupied very big partial punching press stroke space, make the pay-off space less, if adopt traditional manual work to send the material operation, can not influence the pay-off ejection of compact, nevertheless if adopt mechanical automation pay-off mode, when using many times of unit pay-off manipulators, it brings very big inconvenience for automatic feeding mechanism's pay-off, and fix the mould tapping machine who attacks in the punching press stroke and easily take place to touch with automatic feeding mechanism or material itself, influence and attack tooth mechanism normal work.
In order to solve the above-mentioned deficiencies, an integral suspended type in-mold tapping device is provided in the industry, such as the prior patents CN201310133440 and CN103223535A, in which an integral suspended type in-mold tapping device is disclosed, and although the existing integral suspended type in-mold tapping device can solve the problem of interference between tapping and a feeding component or mechanism to a certain extent, it still cannot solve the needs of some practical applications. More specifically, the existing integral suspended type in-mold tapping device aims at that the lower mold of a tapped product does not float, or the machine is integrally larger than the product, the product can be tapped after being pressed down by the machine, or the working procedure of installing the position of the die suspended type in-mold tapping machine does not have other forming, bending process or large stripping stroke of the upper mold. However, for some oversized products, namely products with the external dimension exceeding 500mmX500mm, tapping holes are only arranged at partial positions, and the products need to be bent, formed and blanked outside the tapping positions. And when the material stripping stroke of the upper die is very small or none, the existing integral suspension type in-die tapping device cannot meet the use requirement.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide an improved integral tapping machine which is suitable for small or no stripping stroke, large product floating stroke and requirements on the space in a die occupied by tapping.
In order to realize the purpose, the technical scheme adopted by the invention is as follows:
an improved integral tapping machine comprises an upper base plate, a lower base plate, a tapping assembly, a buoyancy plate, a support column, an equal-height limit column and a nitrogen spring, wherein the tapping assembly comprises a machine body, a transmission gear set, a transmission cup driver, a transmission screw, a tooth rod shell, a screw tap and a chuck; the machine body is clamped between the floating plate and the upper base plate; the machine body is also connected and matched with the upper padding plate through the equal-height limiting columns and the nitrogen springs, and the upper padding plate and the machine body are close to and reset in the vertical direction under the combined action of the equal-height limiting columns and the nitrogen springs; the floating plate is fixedly connected with the lower backing plate through at least two support columns; the transmission gear set is arranged in the machine body; the transmission cup driver is arranged in the machine body and is connected and matched with the transmission gear set; one end of the transmission screw is fixedly arranged on the upper backing plate, and the transmission screw is inserted into a transmission cup driver in the machine body and matched with the transmission cup driver; the tail section of the tooth rod is arranged in the machine body and is connected and matched with the transmission gear set, and the rest of the tooth rod extends out towards the buoyancy lifting plate and is inserted into a tooth rod shell arranged on the buoyancy lifting plate; the front end of the tooth rod is provided with a chuck which is provided with a screw tap.
Furthermore, the outer wall surface of the tooth rod is provided with external threads, and the inner wall surface of the tooth rod shell is provided with internal threads matched with the external threads on the tooth rod.
When the device is implemented, the external mold pushes the floating plate and simultaneously drives the supporting columns to move downwards to compress the distance between the machine body and the upper base plate, and the upper base plate and the machine body form a certain distance by arranging the nitrogen spring between the upper base plate and the machine body. The transmission screw is fixed on the upper backing plate and connected with a transmission cup driver in the machine body, the transmission cup driver is connected with the transmission gear, when the distance between the upper backing plates of the machine body is shortened, namely the nitrogen spring is compressed, the transmission screw pushes the cup driver to rotate and drives the toothed bar to rotate through the rotation of the gear, and the transmission screw and the internal thread of the toothed bar shell are matched to synchronously move upwards simultaneously during rotation through the upper thread of the toothed bar.
The tapping machine is simple in structure and reasonable in design, the problems of short stripping stroke and die space occupation of tapping can be solved by utilizing the structural design, and the production and use requirements are met.
