Summary of the invention
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of extension device service life, safe and reliable, improves the guide twisting device of torsional stability.
The purpose of this utility model is achieved in that
A kind of guide twisting device, comprise casing, the left side of casing is discharging opening, right side is charging aperture, guide channel is provided with between charging aperture and discharging opening, the first guide channel is formed in the casing of described charging aperture side, the casing of discharge outlet is provided with bracing frame, bracing frame is provided with and runs through bracing frame both sides and the parallel up and down eccentric shaft driven by transmission mechanism of axis, two eccentric shafts are all set with torsion roller, the second guide channel that fairlead is formed is provided with in casing between two torsion rollers and the first guide channel, described two torsion rollers are arranged in the mirror image that misplaces up and down.
The utility model is set to further: the concrete structure of the transmission mechanism of described driving eccentric shaft is: two eccentric shafts pass the outer one end of bracing frame and are respectively installed with the worm gear driven by worm engaging.
The utility model is set to further: the bore of described first guide channel is less than the bore of the second guide channel.
The utility model is set to further: described first guide channel and the second guide channel are all in from charging aperture to the diminishing conical cavity in the direction of discharging opening and the straight line die cavity that is connected with conical cavity.
The utility model is set to further: described in be positioned at the first guide channel place casing be provided with waterway, the first guide channel be provided be connected with waterway and the hole for water spraying of spraying water in the first guide channel.
The utility model is set to further: the two ends of described torsion roller are cylindrical roller, the diameter of the cylindrical roller of one end is less than the diameter of other end cylindrical roller, and minor diameter cylindrical roller is connected by the tapered roller increased gradually to major diameter cylindrical roller diameter by minor diameter cylindrical roller with between major diameter cylindrical roller.
The utility model gives prominence to compared to existing technology and useful technique effect is: by arranging the structure of the hole for water spraying of spraying water in the first guide channel on the first guide channel, timely the first guide channel inwall is lowered the temperature, prevent the first guide channel inwall from causing the too high generation deformation of temperature due to the impact of hot steel billet, the service life of extension device, and second the bore of the guide channel bore that is greater than the first guide channel make can not touch during hot steel billet distortion the inwall of the second guide channel, effective protection second guide channel, improve the stability reversed, safe and reliable.
