Embodiment

[0040] Example: a high-speed balanced bi-directional double-flushing can body stretching machine

[0041] The can body stretching machine is composed of a box body, two sets of moulds, two sets of edge-holding mechanisms, two sets of cup-entry mechanisms, two sets of punch rod drive mechanisms and two sets of can-exit mechanisms. As for the rod driving mechanism and the blank-holding mechanism, other structures or mechanisms can adopt the existing technology, so no detailed description and introduction will be made in this embodiment, which can be understood and accepted by those skilled in the art.

[0042] see Figure 1-Figure 4 , the punch driving mechanism is composed of the following components:

[0043] a crankshaft 1 (see figure 2 and Figure 4 ), the crankshaft 1 is rotatably supported by bearings, and the crankshaft 1 is provided with a first crank throw 11, a second crank throw 12, a first blank-holding cam 13 and a second blank-holding cam 14. The first crank t...

Abstract

A high-speed balanced bidirectional double-punch can body stretching machine, including a punch driving mechanism and a blanking mechanism, characterized in that the punch driving mechanism consists of a crankshaft, two identical connecting rods, and two identical slide rails , Two identical sliders and two identical punch rods are connected. Wherein, the crankshaft is rotatably supported by a bearing, and the crankshaft is provided with a first crank throw, a second crank throw, a first blank-holding cam and a second blank-holding cam. Compared with the existing technology, this scheme has two characteristics: first, the pendulum and the secondary connection are omitted in each set of punch rod driving mechanism, which greatly simplifies the structure, and still maintains all the original functions, forming a Element omitted. Second, use two blanking cams, and arrange the first driving point of the first blanking cam opposite to the second driving point of the second blanking cam, so that the first moment and the second moment are opposite in direction, And offset each other, so that when the tank body stretching machine is working, the overall moment balance is maintained on the plane passing the crankshaft axis.

Description

technical field [0001] The invention relates to can body stretching equipment, in particular to a bidirectional double-flush can body stretching machine with better process force and moment balance ability under high-speed working conditions (stretching speed 400 times / min). The so-called can body refers to a metal component having the shape of a can body, such as a can body of a pop can, a can body of a battery case, and other metal objects having a shape of a can body. Background technique [0002] Metal cans are widely used in people's daily life and industry. The typical ones are the can body of the pop can and the casing of the lithium battery in the power battery. The annual usage of these cans is very huge, especially the cans of pop cans. With the continuous improvement of people's living standards, the demand for pop cans is also increasing. [0003] Pop-top cans are usually made of aluminum and iron, and its structure is composed of a can body and an easy-open li...
