Description

TECHNICAL FIELD

[0001] The application relates to the technical field of punching devices, in particular to a punching device for a ring-blowing lifting plate. BACKGROUND

[0002] The ring-blowing device is mainly used for cooling and solidification of fibers during fiber forming in a melt spinning equipment, and uniformly cools the melt stream through the annular airflow to ensure uniform solidification of the yarn, and the ring-blowing lifting plate is the most basic installation plate of the ring-blowing device, and a plurality of fixing holes for installation are formed in the ring-blowing lifting plate.

[0003] A ring-blowing lifting plate is disclosed in the related art, referring to Figure 1 which comprises a frame 01, connecting pipes 02 are welded on both sides of the frame 01, and a plurality of installation holes 03 are formed in the circumferential direction of the frame 01.

[0004] Since the above-mentioned ring-blowing lifting plate is usually a non-standard part, for the punching operation on the non-standard part, the method usually adopted in the prior art is to design a set of fixtures with pre-formed holes, then fix the non-standard part on the fixture, and finally perform the punching operation by manually operating a drilling machine.

[0005] However, in the actual production process, although the pre-formed hole fixture is used for positioning, the worker usually relies on the worker's eyes to judge the approximate drilling position of the drill bit when operating the drilling machine to punch holes, so that the drill bit extends into the pre-formed hole of the fixture to drill holes. Therefore, in order to avoid the direct impact of the drill bit on the fixture, the diameter of the pre-formed hole in the fixture is usually much larger than the diameter of the drill bit.

[0006] Therefore, although the problem of the drill bit directly impacting the fixture is solved to a great extent, there is a large deviation between the position of the hole punched on the non-standard part and the design requirement, so that this method can only be used for processing non-standard parts with low punching precision requirements, and is not suitable for processing non-standard parts with high punching precision requirements, and has defects.
