Description

In-mold tapping device with servo motor as action source

Technical Field

The utility model relates to the field of in-mold tapping, in particular to an in-mold tapping device with a servo motor as an action source.

Background

The in-mold tapping machine is equipment which is matched with a continuous mold to tap the screw hole internal threads of the hardware stamping part, and is widely applied to various part production, in particular to a continuous mold production line because of high processing efficiency and good working stability. First, most of the existing in-mold tapping machines use a punch as a power source, so that the working steps and time of the existing in-mold tapping machines are limited by a machine tool. The tapping is completed only by cooperation with the downward movement of the punch, which means that the work starting time of the in-mold tapping machine is limited and fixed, and flexible adjustment cannot be performed according to production requirements.

Secondly, the existing in-mold tapping machine does not have a tapping torque adjusting function. When producing the product with the same specification but different screw specifications or materials, the product can work smoothly only by matching with different in-mold tapping machines. This not only increases the production cost but also reduces the production efficiency. For example, under the same punch stroke, if a deep and thick thread is to be tapped, a problem arises that the down stroke and torque cannot be well adapted.

Finally, the existing multi-die tapping machine does not have a positioning function, only realizes up-and-down movement and tapping, and does not guarantee the position of a tapped product.

In the above prior art, it should be noted that, in the industry, a servo motor is used to replace the screw and the screw sleeve, but the problems of speed change and torque adjustment are not solved, and at the same time, a positioning mechanism arranged on the tapping device is not found.

In view of the foregoing, there remains room for improvement and a need for an in-mold tapping device.
