Problems solved by technology

[0003] The existing sieve body production process is complex, and the openings on the existing sieve body are machined after welding. The processing equipment must also have: 1. The rotation and feed movement of the power head (used to clamp the drill bit) ; 2. The horizontal movement, up and down movement of the power head (or worktable); 3. The circular rotation indexing of the workpiece (sieve body) or the rotation and indexing movement of the power head around the workpiece. Such processing equipment (processing centers, special-purpose machine tools) processing has a long construction period and high cost, and there are not many equipments that can process such large-sized workpieces; moreover, some holes are blocked by diagonal braces, which increases the difficulty of conventional equipment implementation (this part of the holes needs to be processed from The inside of the sieve body is drilled outward), the biggest problem in the common production process of the existing sieve body is that it is difficult to perform rapid processing during the processing of the skeleton combined hole, which affects work efficiency

Embodiment 1

[0028] like figure 1 , figure 2 and Figure 5 As shown, the manufacturing process of the trommel screen of the present invention includes a longitudinal frame 3 and a combined die frame 10, the two ends of the longitudinal frame 3 are respectively welded with an inlet flange 1 and an outlet flange 6, and the longitudinal frame 3 is welded with cross braces 2, Circumferential rods 4 and diagonal braces 5, in order to optimize the production process, the biggest problem in the common production process of the screen body - "frame combination hole processing" process optimization is carried out after the longitudinal frame 3 is blanked, and the longitudinal frame 3 is drilled first and then drilled. Assembly, welding.

[0029] In this embodiment, 38 combined holes of Φ15mm and 22 holes of Φ23mm are arranged on each longitudinal frame 3, and the allowable parallelism error of the holes on each two longitudinal frames 3 is less than 1mm. Drilling die, when processing, first fit...

Embodiment 2

[0031] see image 3 , made further improvements on the basis of Example 1:

[0032] In this embodiment, the combined mold is composed of a cylinder 7 formed by a steel plate, an annular web 8, a T-shaped cross brace 9 and a combined mold skeleton 10. The annular web 8 and the T-shaped cross brace 9 reinforce the cylinder 7 function to prevent the "combination mold" from being deformed.

[0033] There are 12 positioning holes evenly distributed on the upper circumference of the inner side of the cylinder 7, and two shaft diameters for positioning are machined on the pin shaft, which are respectively matched with the positioning holes of the combined mold and the corresponding holes of the combined mold frame 10. Position the 12 combined mold skeletons 10 on the circumference to meet the requirements of the drawing; the axial distance between the two positioning shaft diameters on the pin shaft controls the inner diameter of the assembled screen body. After the combined mold is...

Embodiment 3

[0035] see figure 1 and Figure 4 , made further improvements on the basis of Example 1:

[0036] In order to drill and pass the inspection of the longitudinal frame 3 and the combined mold frame 10 to determine the position of each other through the pin shaft to ensure accurate assembly, first install four combined mold frames 10 in the 90° direction, and then vertically assemble them to the inlet flange 1 On the end face of the upper and lower composite molds, the combined mold frame 10 is aligned with the cross center line marked on the surface of the inlet flange 1, so that the centers of the upper and lower combined molds coincide with the center of the inlet flange 1.

[0037] In this embodiment, a laser measuring instrument is used to correct and align the verticality of the combined mold frame 10 and the inlet flange 1 and the parallelism between the centerlines of the combined holes of every two combined mold frames 10, tighten the pins and nuts, The combined mold f...

Abstract

The manufacturing process of the drum screen comprises a longitudinal framework and a combined die framework, an inlet flange and an outlet flange are welded to the two ends of the longitudinal framework respectively, and a cross-shaped inclined strut, an annular rod and an inclined strut are welded to the longitudinal framework. The capacity can be expanded without adding new production equipment; the manufacturing period is shortened, the production progress is convenient to control, and the delivery time is guaranteed; the common drilling machine is used for machining the combined holes, the machining cost is only one tenth of that of high-precision equipment, and the manufacturing cost is greatly saved; after the combination die is used, the diameter size can be effectively controlled, and simplicity and practicability are achieved; products do not need outsourcing processing, and the outsourcing transportation cost of the screen body is saved; and experience is accumulated for subsequent manufacturing of a screen body with a larger specification.

Description

technical field [0001] The invention relates to the technical field of trommel screen manufacturing, in particular to a trommel screen manufacturing process and a use method thereof. Background technique [0002] The trommel screen is mostly used for the classification of large and small lumps in chemical, metallurgy, coal and other industries, as well as the separation of sand, gravel, powder and other substances. [0003] The existing tanning process is complicated. The openings on the existing sieve body are machined after the welding is completed. The processing equipment must be equipped with: 1. The rotation and feeding motion of the power head (used for clamping the drill bit) ; 2. The horizontal movement, up and down movement of the power head (or worktable); 3. The circular rotation indexing of the workpiece (screen body) or the rotation and indexing movement of the power head around the workpiece, etc. Center, special machine tools) processing has a long construct...
