Can making device for metal can

Abstract

The invention provides a can making device for a metal can. The device comprises a rounding mechanism and a rotating shaft moving assembly, and is characterized in that one side of the outer surface of the rounding mechanism is movably connected with a conveying belt; the side, far away from the outer surface of the rounding mechanism, of the conveying belt is movably connected with a welding seammechanism; a supplementary coating mechanism is arranged at one side of the outer surface, opposite to the rounding mechanism, of the welding seam mechanism; an expansion cone and expansion rib mechanism is arranged at one side of the outer surface, opposite to the welding seam mechanism, of the supplementary coating mechanism; a tank erecting mechanism is arranged at one side of the outer surface, opposite to the supplementary coating mechanism, of the expansion cone and expansion rib mechanism; and a flanging mechanism is arranged at one side of the outer surface, opposite to the expansioncone and expansion rib mechanism, of the tank erecting mechanism. According to the can making device for the metal can, cone expanding and rib expanding machining procedures can be conducted on two tinplate three-piece can semi-finished products at the same time, and the cone expanding machining procedure and the rib expanding machining procedure are completed on the same equipment in a unified mode, so that the machining procedures are reduced, and the working efficiency and the productivity are greatly improved.

Description

technical field [0001] The invention relates to the technical field of can making devices, in particular to a can making device for metal cans. Background technique [0002] The can making machine for metal cans is a machine that uses metal materials to manufacture cans. The objects it processes mainly include tinplate, chrome-plated steel sheets and aluminum alloy sheets. The types of cans it processes include two pieces There are two types of cans and three-piece cans, of which three-piece cans are the most common. The can-making process of a three-piece metal can maker usually includes cutting boards, feeding, rounding, welding, re-coating, vertical cans, and expanding cones. , Expanding ribs, flanging, lower sealing, U-turn and upper sealing. [0003] However, there are certain defects in the existing metal can making machine: 1. The production line is long, the processing procedures are many, and the machinery and equipment are complicated. 2. The two processing proce...

Problems solved by technology

[0003] However, there are certain defects in the existing metal can making machine: 1. The production line is long, the processing procedures are many, and the machinery and equipment are complicated. 2. The two processing procedures of expanding the cone and expanding the rib can only process one processing object at the same time at a time, and the efficiency is very low; 3. In the process of expanding the cone and expanding the rib During the first processing procedure, it is necessary to have a pusher to lift the metal tank body until it is completely inserted into the mold for the expansion cone and expansion ribs before the processing of the expansion cone and expansion ribs can be carried out. For the two processing procedures of the expansion cone and expansion ribs The number of pushers needs to be at least four, and the pushers need to take the power of the expansion cone and expansion machine equipment to support its operation
