Abstract
The invention discloses a drawing machine. A quadrilateral connecting rod structure is composed of a first clamp block, a second clamp block, a first connecting rod and a second connecting rod. The quadrilateral structure is not stable, so, when drawing, one end of things to be drawn passes through a mould and enters into a clamping opening aperture, and is clamped by the first clamp block and the second clamp block; and clamps are driven to move toward a direction away from the mould by a rotating shaft which is connected with a clamper and which is arranged between the first connecting rod and the second connecting rod, when the clamper is taken to move far away from the mould by a chain of a connecting mechanism. Due to the presence of drawing resistance, the first connecting rod and the second connecting rod are close up, the first clamp block and the second clamp block are also close up, and the clamping opening aperture is reduced, when the quadrilateral connecting rod structure begins to co-move, so that things to be drawn can be clamped more tightly, move toward the direction away from the mould along with the chain, and be drawn to appropriate sizes through the mould. Smoothly drawing of the mould is realized through transmission chains by the drawing machine.
