Problems solved by technology

If the hole is drilled first and then bent, the position of the hole will be seriously deviated, resulting in failure to assemble
If the holes are bent first and then drilled, the positions of the holes are difficult to determine because the holes are arranged along the curve
Since no reasonable drilling method has been found so far, the drilling accuracy is difficult to meet the assembly requirements in the later stage, which seriously affects the smooth progress of production

Embodiment Construction

[0032] The invention provides a drill matching method for the floating screen frame of the banana-shaped relaxation screen, so as to ensure the smooth progress of later assembly of the banana-shaped relaxation screen.

[0033] see figure 1 , figure 2 and image 3 , the present invention first makes side square drill template 1, upper drill template 5 and lower drill template 6 according to the assembly diagram of banana-shaped relaxation screen, and then they are combined with the upper support angle steel 2 made, the lower support angle steel 3 and the floating screen frame 4 are assembled together to form a drill assembly, and finally the drill assembly is placed on a CNC drilling machine to drill holes for the upper support angle steel 2, the lower support angle steel 3 and the floating screen frame 4.

[0034] In the assembly of drill components, the side square drill template 1 replaces the actual side plate of the relaxed screen, and the material is automatically cut ...

Abstract

The invention discloses a distribution-drilling method for a floating screen frame of a banana-shaped flip-flow screen. The method comprises the following steps: a, manufacturing a side square drill template; b, manufacturing an upper drill template; c, manufacturing a lower drill template; d, assembling a distribution-drilling part assembly; e, using a numerical-control drilling machine and a boring machine to drill upper support angle steel, lower support angle steel and the floating screen frame; and f, dismounting the distribution-drilling part assembly, accomplishing distribution-drillingof the floating screen frame once, and utilizing the side square drill template, the upper drill template, the lower drill template, a support block and an auxiliary cushion plate to perform distribution-drilling on next floating screen frame. The distribution-drilling part assembly consisting of the side square drill template, the upper drill template, the lower drill template, the auxiliary cushion plate and the support block, which can be used in a circulating mode, is adopted to perform all-around distribution-drilling on the upper support angle steel, the lower support angle steel and the floating screen frame, so that drilling difficulty is greatly reduced, drilling precision of the floating screen frame is improved, and smooth production is guaranteed.

Description

technical field [0001] The invention relates to a drilling method for a channel steel floating frame in a banana-shaped relaxation screen for coal preparation, and belongs to the technical field of screening equipment. Background technique [0002] The relaxation screen is a new type of dry screening equipment currently used for wet fine-grained coal, and plays an important role in the development of clean coal technology. The screening of wet fine-grained viscous materials is a hot and difficult point in the research of screening technology at home and abroad. The wet materials stick to each other and form agglomerates, which reduce the effective screening area and make the screening process difficult to complete. The relaxation screen adopts polyurethane sieve plate. During use, the sieve plate itself makes a large deflection movement, and the sieve holes always make a deflection movement of one piece and one relaxation. The moist fine-grained coal on the hole is kneaded ...
