Description
Technical Field
The invention relates to the technical field of metal wire drawing, in particular to a pressure cone with a pressure cone guide block for drawing.
Background
The metal wire drawing is a shaping processing method that the front end of the metal wire is acted by external force, and the metal blank is pulled out from a die hole smaller than the cross section of the blank to obtain products with corresponding shapes and sizes, the existing drawing process needs to use lubricating agents, namely grease lubricating agents and soap powder lubricating agents, the grease lubricating agents have good lubricating effect, but after the drawing, the metal surface can be adhered with a lot of greasy dirt, the metal surface can be cleaned by using a special cleaning machine, and the soap powder lubricating agents are generally in powder shape and are adsorbed on the metal surface by virtue of molecular polarity, and the lubricating agents are in a soft melting state under the action of pressure and temperature after entering a deformation area so as to play a lubricating role.
When the existing soap powder lubricant is used, firstly, a hopper containing soap powder is placed in front of a die, the soap powder is brought into the die by metal in the drawing process, but the soap powder lubricant is a powdery lubricant and has lower fluidity than an oil lubricant, so that the soap powder lubricant cannot be brought into the die well, and the lubricating effect is poor.
Disclosure of Invention
The present invention is directed to a pressure cone for drawing having a pressure cone guide block, which solves the problems set forth in the background art.
In order to achieve the above purpose, the present invention provides the following technical solutions: the utility model provides a draw with pressure awl that has pressure awl guide block, includes the pressure awl of threaded connection pressure awl guide block, the inlet wire hole that is used for the threading has been seted up to the pressure awl guide block, and at the top of pressure awl guide block set up the spacing hole with the inlet wire hole intercommunication, the interior taper hole of the spacing hole of intercommunication has been seted up to the pressure awl, and has seted up the row powder hole of circumference evenly arranging on the inner wall in interior taper hole.
The inner wall of the inner taper hole is provided with 6 powder discharge holes, and the included angle of the powder discharge holes relative to the central axis of the pressure cone is 30 degrees.
The inner cone angle alpha of the limiting hole is 1-3 degrees.
The inner cone angle beta of the wire inlet hole is 11 degrees.
The inner taper angle theta of the inner taper hole is 12 DEG to 16 deg.
According to the technical scheme, the pressure cone and the pressure cone guide block are designed, so that a good lubricating effect is achieved on the drawing of the metal wire, soap powder is not easy to accumulate in the device, and the high-efficiency use requirement of the drawing device is met.
