Description

Technical Field

[0001] The invention relates to the technical field of six-end face top press processing, and in particular to a processing device and a processing method for a hinge beam ear fan of a six-end face top press. Background Art

[0002] The main equipment used for the synthesis of artificial superhard materials is a hinged six-end press. The six-end press usually has six hinge beams assembled together through a pin shaft. The machining accuracy of the hinge beam ear fan directly affects the assembly accuracy of the six-end press. Poor machining accuracy will cause the hinge beam to be unable to be assembled. The traditional method is to use a gantry milling machine or a horizontal milling machine to continue processing the hinge beam ear fan. When using a gantry milling machine to process the hinge beam ear fan, it is necessary to use an ordinary angle head to feed from the side end face of the hinge beam. Due to the small space and deep depth of the hinge beam ear fan, the internal area of ​​the ear fan can only be processed by lengthening the tool bar. When a milling cutter with a tool bar length-to-diameter ratio greater than 3 is used for processing, the tool bar has poor rigidity, large vibration, and increased number of cuts. The resulting effects are poor accuracy, low efficiency, and poor surface end processing quality, which will affect the accuracy of the machine tool in the long run.

[0003] The horizontal boring machine does not require an angle head, but the tool bar still needs to be lengthened, especially when processing the root of the ear fan. The spindle extends to the maximum length, vibration cannot be avoided, and the requirements of fine processing cannot be met. In addition, the above two processing methods both use the side end face of the disc milling cutter for processing. Due to vibration, the cutting amount is small. The end face to be processed of a hinge beam ear fan must be fed repeatedly at least 4 times to completely remove the excess. In addition, the number of passes of the side end milling increases, and the efficiency is low. According to statistics, it takes two days to complete the processing of a hinge beam ear fan. In order to improve the processing efficiency, the side milling can only be changed to end milling.

[0004] It is impossible to perform high-precision and high-efficiency processing of hinge beam ears by traditional processing methods. In this engineering background, a processing method for the ears of hinge beams of forged six-end face press was invented, which can achieve the requirements of high-precision processing of hinge beam ears and greatly improve the efficiency, thus solving the processing problems of key processes of hinge beams of six-end face press.

[0066] The present invention relates to a processing device and method for the ear fan of a hinge beam of a six-end face press. A disc milling cutter 44 is installed on the side of a shell body 16 and the lower end of the shell body 16, and the processing surface of the ear fan 5 is milled by the end face of the disc milling cutter 44, which changes the existing side processing using the disc milling cutter 44.

While improving efficiency, the accuracy of the ear fan 5 is also guaranteed. At the same time, the present invention positions the hinge beam through the cooperation of the center seat 9 and the positioning plate 6, which solves the problem that the hinge beam is difficult to align when the large surface is facing downward, reduces the auxiliary time for alignment, and ensures the uniformity of the positioning reference. By adopting the processing method of the present invention, the excess to be processed can be removed in one feed, which has the advantage of a high removal rate, and the efficiency of processing a surface to be processed is significantly improved. On the premise of ensuring the processing quality, the program segments are small, the non-cutting time is reduced, the processing cycle of the workpiece is shortened, and the effect of high quality and time saving is achieved.
