Description

  The present invention relates to a kind of screw forming machine, the screw forming machine can form a screw part of a screw and remove sharp burrs from the tip of the screw part. It is related with what can do processing operations, such as a groove.

  All of the traditional thread rolling machines are primary machines, and can only process the threaded part of the screw on the workpiece. Therefore, after the threaded part is processed into the screw, the screw is removed from the thread rolling machine. A screw product cannot be completed without removing and chamfering it with a tool for burr correction.

  The manufacturing steps of the traditional screw processing method are cumbersome and have to be relied upon by human hands, which leads to disadvantages such as increased costs and reduced production. For this reason, the present applicant has submitted the invention described in Patent Document 1 (“Screw Forming Machine”), which has been made to solve various problems in traditional screw processing. The molding machine includes a machine seat unit, a vertical movement unit, a horizontal movement unit, a spindle unit, a work table, a workpiece holding unit, a lifting unit, and a chamfering unit. The screw machining tool on the spindle unit eliminates the need to remove the workpiece after machining the screw thread on the workpiece, and further removes sharp burrs on the screw thread with the chamfering unit, thereby speeding up the manufacturing by computer automated machining. And the advantages of eliminating the inconvenience of manual work.

  The above-described screw forming machine overcomes the problem of manual burr correction by computer automation. However, the chamfering tool of the chamfering unit used to remove sharp burrs is a disk-shaped tool, and this tool is hung on one side of the machine head. This tool is very accessible and creates operational obstacles and dangers. Next, the disk-shaped tool is limited to the function of removing an acute angle, and cannot be used for other processing operations.
