Embodiment Construction

[0020] Such as figure 1 As shown, the cylinder forming mechanism 100 of the present invention is used to extrude the metal plate 200 to form the cylinder, and the cylinder forming mechanism 100 includes a frame 1, a driving mechanism 2, a punch 3, a pair of dies, namely Left and right dies 41, 42, a pair of push mechanisms 5, an upper die assembly 6 and a lower die assembly 7; the punch 3 is fixed on the frame 1 and is connected to the cross section of the cylinder The same, specifically, the punch 3 is a strip type, one end of which is vertically fixed on the plane of the frame 1, the cross section of the punch 3 is a rectangular structure and the four corners are arc-shaped transitions, and The punch 3 is arranged obliquely so that the two arc surfaces 3a, 3b on the same diagonal line are the uppermost end and the lowermost end of the punch 3 respectively.

[0021] combine figure 1 see figure 2 The pushing mechanism 5 is symmetrically located on both sides of the punch 3...

Abstract

The invention discloses a cylinder shaping mechanism, which is applicable to form a cylinder by extruding a metal sheet. The cylinder shaping mechanism comprises a frame, a driving mechanism, a convex die, a pair of concave dies and a pair of pushing mechanisms, wherein the cross section of the convex die is the same as that of the cylinder body, and the convex die is fixed on the frame; the pushing mechanism comprises a first connecting rod, a second connecting rod and a swing arm; one end of the first connecting rod is pivoted with one end of the swing arm, the swing arm is arranged in a horizontal manner and the middle part of the swing arm is pivoted to the frame; the other end of the swing arm is pivoted with one end of the second connecting rod, the concave dies are arranged at both sides of the convex die and provided with pivoting parts and rotating parts; the pivoting parts are pivoted on the frame and the rotating part are pivoted on the other end of the second connecting rod; the pushing mechanism can be driven by the driving mechanism simultaneously, so that the convex die can be coated by two concave dies; and therefore, the cylinder body is formed by extruding the metal sheet. By adopting the cylinder shaping mechanism, the shaping steps can be simplified and the producing efficiency is improved.

Description

technical field [0001] The invention relates to a forming machine, in particular to a cylinder forming mechanism which simplifies forming steps and improves production efficiency. Background technique [0002] With the improvement of living standards, people's requirements for the quality of consumer goods are also increasing. For some food with high storage requirements, it is necessary to use metal cans for packaging for convenient storage. Because metal cans have the advantages of anti-collision, strong sealing performance, and beautiful appearance, they are deeply loved by consumers. Therefore, various Various metal can products. [0003] The metal tank body is mainly composed of a cylinder body, a bottom cover and a top cover. The bottom cover is set on the bottom end of the cylinder body and fixedly connected with the cylinder body to form a tank body. The top cover is connected to the top of the tank body in an openable or closed manner, so that Form an internal spa...
