[0106] Such as Figure 13 As shown, the cutting tool 40 abuts against the base (root) of the burr 132 formed on the parting line 121 located at the valley 124C sandwiched between the peaks 124A, 124B of the workpiece 130 . On the tip side of the cutting tool 40, there are: a cutting edge portion 40A protruding corresponding to the root of the burr 132 and having a width of about several millimeters; Figure 13 In the center is the mountain portion 124B) corresponding to the curved profile portion 40B that does not constitute the cutting edge; and the cutting tool main body portion 40C. In the cutting tool 40 according to the third embodiment, in a state where the contoured portion 40B and the mountain portion 124B are in slidable contact, the cutting tool main body portion 40C rides over the mountain portion 124B, and the cutting edge portion 40A and the valley portion 124C are formed in the same state. Burr 132 abuts.

[0107] In this embodiment, as in the above-mentioned f...

Abstract

There is provided a deburring system for enabling perfect automation of deburring with which burr of a resin molded article is substantiallyperfectly removed after the resinmolded article is manufactured at low cost not by using an expensive resin molding machine, but by using a conventional general-purpose molding machine. Furthermore, there are provided a deburring apparatus and a cutter blade with which burr of a resin molded article having an unstable shape can be easily and cleanly removed from the root thereof without using any expensive control device and any positioning device and also without using any expensive copying device.

Description

technical field [0001] The present invention relates to a deburring system, a deburring device, and a cutting tool for removing burrs formed on a parting line of workpieces such as resin molded products. Background technique [0002] In general, in resin molded products such as nursing bed parts, copier parts, tool boxes, thermal insulation resin boxes, automotive air spoilers, automotive sun visors, automotive center pillars, and automotive interior sheets, During molding, for example, burrs are formed on the parting line. The burr is removed by a burr removal device after forming. [0003] In the past, various methods have been adopted for the removal of burrs according to the workpiece or various conditions: for example, laser irradiation, hot air, flame irradiation, plasma irradiation, infrared irradiation, etc.; Excision; Excision by various grinding (rolling, polishing, use of free abrasives, use of fixed abrasives); Excision by water spray; Excision by ultrasonic cl...
