Dryer barrel body and manufacturing technology thereof

Abstract

The invention discloses a dryer barrel body and a manufacturing technology thereof, and belongs to the technical field of dryers. The dryer barrel body comprises a main body part and flanges arrangedat the two ends of the main body part, the main body is formed by splicing a plurality of side plates, and the flanges are integrally formed; and the connection end of every two adjacent side plates is provided with a plurality of positioning holes, and positioning pieces are arranged in the positioning holes. The manufacturing technology of the dryer barrel body comprises the steps that 1, the multiple positioning holes are drilled out in the corresponding positions of the spliced ends of the four steel plates; 2, by adopting automatic equipment, two spliced ends of two identical steel platesof the four steel plates are bent to form bent parts, and two spliced ends of the other two identical steel plates of the four steel plates are bent to form hook parts; 3, the four steel plates are sequentially spliced to form the barrel body, wherein the same steel plates are arranged on the opposite sides, the bent parts of the adjacent steel plates are matched with the corresponding hook parts, the multiple positioning holes of the adjacent steel plates correspond in sequence, and fixing is conducted by arranging the positioning pieces in the positioning holes; and 4, the flanges are welded to the outer sides of the two ends of the barrel body. According to the dryer barrel body and the manufacturing technology thereof, machining is convenient, meanwhile, the structure strength is high, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a dryer cylinder and a manufacturing process thereof. Background technique [0002] With the rapid progress and development of my country's economy and science and technology in recent years, my country's agriculture has also achieved rapid development, the level of agricultural automation has been greatly improved, and the production efficiency of grain has also achieved a great leap. However, in terms of grain drying and storage, the vast majority of farmers in our country still use the original drying method, which is not only inefficient, but also in the event of continuous rainy weather, the grain cannot be dried, which will lead to mold and germination of the grain, resulting in economic losses. Therefore, it is imminent to carry out modern improvement on grain drying, and grain dryers have also emerged as the times require. [0003] As an important part of the dryer, the c...

AI Technical Summary

Problems solved by technology

The existing dryer body is generally welded by a "concave" steel plate bent twice and a steel plate. Since the "concave" steel plate is formed by bending, its structure The strength is relatively low. At the same time, welding with the bent steel plate requires high precision control, which is time-consuming and laborious

In addition, due to the large volume of the cylinder, the bending operation of the "concave" steel plate cannot be done automatically by the machine, and it needs to be done manually

To sum up, the existing dryer cylinder has the problems of low structural strength and time-consuming and laborious processing.
