Cutting device for straightening and cutting machine

Abstract

The invention discloses a cutting device for a straightening and cutting machine, which is characterized in that it includes a frame body, a workpiece limit mechanism, a fixed knife and a moving knife mechanism; the frame body includes a vertical plate and a top plate, and the vertical plate has a The workpiece channel; the workpiece limit mechanism includes a left adjustment rod, a right adjustment rod and an upper adjustment rod; On the top wall, as well as the first ends of the left adjusting rod, the right adjusting rod and the upper adjusting rod are located in the workpiece channel and form a limiting channel; The low point of the channel is on the same horizontal line; the moving knife mechanism includes a moving knife and an oil cylinder, and the oil cylinder is installed on the top plate and connected with the moving knife to drive the moving knife to move relative to the fixed knife. The invention can not only improve the cutting quality of workpieces, but also increase the service life of cutting knives and reduce the replacement cycle of cutting knives.

Description

technical field [0001] The invention relates to a mechanical shearing mechanism, more specifically to a cutting device of a straightening and cutting machine. Background technique [0002] During the production of metal wires, for the convenience of storage and transportation, the wires need to be coiled into coils. But when wire rod is in use, it is often necessary to cut the wire rod into an equal length after being straightened. At present, a straightening machine is mainly used to straighten the steel bar, and the straightened steel bar is cut off by a cutting mechanism. [0003] In the prior art, when the workpiece enters the cutting mechanism for cutting, it does not have a limit mechanism, or the limit mechanism is outside the cutting mechanism (ie, the guide wheel) and is far away from the cutting mechanism, resulting in the workpiece being cut. At the same time, the problem of beating occurs in the cut part, which affects the quality of cutting, and the cutting kni...

Problems solved by technology

[0003] In the prior art, when the workpiece enters the cutting mechanism for cutting, it does not have a limit mechanism, or the limit mechanism is outside the cutting mechanism (ie, the guide wheel) and is far away from the cutting mechanism, resulting in the workpiece being cut. When the cutting part jumps, it affects the quality of cutting, and the cutting knife is easily damaged, resulting in frequent replacement of the cutting knife.
