Problems solved by technology

[0004] When drawing a linear product, no matter the chain equipment, steel rope equipment or hydraulic equipment, it is used to first pass the workpiece pressure head to be drawn through the drawing die. The fixture is clamped and then drawn. This kind of production is reciprocating, and the movement of the drawn workpiece has a pause. It cannot achieve stable and uninterrupted continuous production like the disc-type production equipment.

Embodiment

[0036] The pre-pressing head of the workpiece 1 to be drawn passes through the drawing die 2, the driving sprocket 13 rotates to drive the chain 11 to move at a constant speed and drives the driven sprocket 14 to rotate, the eccentric pressing wheel base 4, the eccentric pressing wheel axle 5, The eccentric pressing mechanism composed of the eccentric pressing wheel 6, the driving lever 7 and the spring 8 moves through the starting locking slide rail 9. When the driving lever 7 is started and the locking sliding rail 9 is pushed in the direction opposite to the chain movement direction 12, the driving lever 7 Drive the rotation of the eccentric compression wheels 6 to increase the outer edge distance of the two eccentric compression wheels 6 in the same group, and the group of eccentric compression wheels 6 moves to the same level as the drawing workpiece 3. Open to the maximum along the distance, when the group of eccentric compression wheels 6 and the drawing workpiece 3 ...

Abstract

The invention discloses a continuous chain-type straight line drawing device, which comprises a drawing mold, eccentric compression mechanisms, a circulating chain transmission mechanism, a locking starting slide rail and a locking unlocking slide rail, wherein the eccentric compression mechanisms are arranged on a chain at intervals; and when deflector rods on the eccentric compression mechanisms penetrate through the locking starting slide rail and the locking unlocking slide rail, eccentric compression wheels are alternately in starting, locking and starting states due to pushing of the slide rails and pulling of a spring, and a drawing workpiece is stably, smoothly and uninterruptedly pulled out in a straight line type in cycles.

Description

technical field [0001] The invention belongs to the metal drawing equipment structure technology, in particular to a straight line continuous metal drawing equipment structure. Background technique [0002] Drawing equipment is divided into chain type, steel rope type, hydraulic type and disc type according to the overall structure. [0003] For pipes, bars or special-shaped materials that need to be delivered in straight strips, chain, steel rope, and hydraulic equipment are mainly used for production; disc production equipment is mainly used for wire processing that is delivered in coils. [0004] When drawing linear products, whether it is chain equipment, steel rope equipment or hydraulic equipment, the pressure head of the workpiece to be drawn is first passed through the drawing die and clamped with a fixture, and then drawn. This kind of production is reciprocating. There is a pause in the movement of the drawn workpiece, which cannot achieve stable and uninterrup...
