Abstract

PURPOSE:To obtain a worked article having an intricate shape with excellent working accuracy by working the part to be pressed of a blank material which is so held as to be movable with the degree of freedom of >=3 axes by means of punches which permit control of stroke while comparing the shape of said part with a set profile. CONSTITUTION:Information on the profile and working accuracy of a worked article 17 is inputted to an electronic computer and information relating to working and measuring conditions is inputted to an NC control panel. A step part 17a is first worked then a step part 17b is worked. The respective step parts are finely segmented and are so set that the area to be worked each time decreases. When the free forging device is turned on, a 3-axial driving part operates and the first working position of a blank material 1 is moved between upper and lower punches 11 and 12 by the finger part 10 of a handling device 9 and the punch 11 of a press 7 starts working. The article 17 is moved to a measuring part 8 by the finger part 10 upon completion of the inputted working and the profile of the worked article is measured and is compared with the inputted profile. If there is a part where the size is larger than the range of permissible accuracy, said part is worked again by correcting the stroke of the punch 11 and such operation is repeated.

The problem with the embodiment described above is that the profile of the machined product and the electronically set product profile are compared and the machining is repeated until the dimensions are within the allowable accuracy range.
You can also obtain a processed product with a strength of 11 and a glass rating of 1. In addition, this free forging device moves with degrees of freedom on four axes and clamps the material 1 with the filler part 10, so it has degrees of freedom on two axes like in the past. It is possible to process workpieces with complex shapes, such as the workpiece 17 shown in FIG. Furthermore, since the area to be pressurized is made smaller each time the pressure is applied, the force and force are reduced, the free forging equipment becomes smaller, and equipment costs can be reduced.7) ).

[Claims] 1. A pressurized portion of a material held so as to be movable with at least six axes of freedom is pressurized by a punch whose stroke is controlled so that a small pressurized area is applied each time. Compare the profile of the workpiece with a preset force and the profile of the pressurized part, and if there is a part to be machined whose dimensions are larger than the permissible accuracy range, then press the part with the punch. A free forging method characterized by repeating the steps of correcting stubble and reworking to obtain a processed product of a desired shape. 2. A handling device having a finger portion for grasping the material and capable of moving the material with at least six axes of freedom; and a press having a punch 7 capable of stroking the material. A measurement unit that can measure the profile of the zero-pressure extraction force portion of the material and a signal related to the profile input from this measurement unit are used to compare it with a preset workpiece profile and determine the dimensions within the allowable accuracy range N. an electronic computer that calculates the dimensional difference and position of a large machined part, calculates rework information for reworking the machined part based on the calculated values, and stores the information;
The above-mentioned re-caroe information is called up from this computer and outputted to the above-mentioned handling device and press side, and the movement amount of the above-mentioned finger portion is determined respectively. NC that can command the stroke amount of the punch
A free forging device characterized by being equipped with a control panel.
