Description

Automatic carousel chasing bar

Technical Field

Background

Tapping refers to the process of screwing a tap into a bottom hole to be drilled with a certain torque to form an internal thread. The threaded holes on the sheet metal in the sheet metal industry cannot be directly machined and formed by the stamping die punch press or the turret punch press, so that tapping of the reserved holes becomes a common process for subsequent machining of sheet metal parts. In the traditional process, operators can realize threaded hole processing of different products by changing different clamps and changing the tapping head distance on the tapping machine.

Tapping is a complex combined motion in which the tap is fed radially while rotating. The sheet metal part belongs to a thin-wall part, the threaded holes are smaller, and the sheet metal part is machined by the extrusion tap, so that the radial movement speed of tapping is slow due to multiple factors. The clamp of the traditional tapping machine is arranged below the tap, and a high enough operation space is needed to be reserved for manually taking and placing products. Thus, a larger distance results in a longer time for the tapping machine to make an ineffective lifting rotation, resulting in a low tapping efficiency.

The operator's operation steps are: the material area to be processed is used for taking products, wiping greasy dirt, placing the products into a clamp of a tapping machine, pressing a starting switch, tapping, and placing finished products into the finished material area. The operation steps of operators are more, the operation time is longer, the tapping machine is in waiting time longer, and the tapping efficiency is seriously affected.
