Problems solved by technology

[0003]The existing drawing machine uses a single-sided cam to drive the drawing trolley to move, relying on the hard contact between the roller of the drawing trolley and the curved surface of the single-sided cam to produce the drawing force to realize the pulling of the object to be pulled, so the stability of the pulling operation is poor

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.

Description

[0001] technical field [0002] The invention relates to a drawing machine. Background technique [0003] The existing drawing machine uses a single-sided cam to drive the drawing trolley to move, relying on the drawing force generated by the hard contact between the roller of the drawing trolley and the curved surface of the single-sided cam to realize the drawing of the object to be drawn. The stability of operation is poor. Contents of the invention [0004] The purpose of the present invention is to provide a drawing machine which can realize smooth drawing through the movement of the transmission chain with the holder and the clamp. [0005] In order to achieve the above object, the technical solution adopted by the present invention is: a drawing machine, including a machine base, a mold mounting seat set on the machine base for installing a mold, and a driving sprocket set on the machine base and the driven sprocket, the transmission chain connecting the driving s...
