Warm forging deep hole extrusion die

Abstract

The invention discloses a warm forging deep hole extrusion die, and particularly relates to the field of dies. The warm forging deep hole extrusion die comprises a top discharging plate mechanism, wherein a spraying ring mechanism is fixedly mounted in the center of the top discharging plate mechanism; side connecting rod mechanisms are fixedly mounted on the two sides of the top discharging plate mechanism; a stamping type die mechanism penetrating through the spraying ring mechanism is arranged at the center position of the top discharging plate mechanism; a bottom pressing plate mechanism is fixedly mounted at the bottom of the top discharging plate mechanism; a punch mechanism is inserted into the center position of the bottom pressing plate mechanism; and a middle pressing ring mechanism is connected to the outer portion of the punch mechanism in a sleeving mode. Through arrangement of the spraying ring mechanism, the top discharging plate mechanism is fixed to the bottom pressing plate mechanism and the middle pressing ring mechanism to achieve the discharging effect, and the spraying ring mechanism cleans and sprays onto the punch mechanism in the top discharging plate mechanism through fixed liquid leakage holes and side liquid leakage holes formed in the side wall of a middle material cavity, therefore, the punch mechanism can be quickly cooled.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a warm forging and extrusion deep hole die. Background technique [0002] In addition to the mold itself, it also needs mold bases, mold bases, mold cores, and parts ejection devices. These parts are generally made into general-purpose types. Mold companies need to be bigger and more refined, according to market demand, technology, and capital. , equipment and other conditions, determine product positioning and market positioning, these practices are especially worth learning and learning from small mold companies, and concentrate on gradually forming their own technical and product advantages. Therefore, my country's mold companies must actively strive to learn from the experience of these advanced foreign companies , for its better development in the future, the so-called deep hole processing is the hole whose length to hole diameter ratio is greater than 6. In general deep hole pro...

[0002] In addition to the mold itself, it also needs mold bases, mold bases, mold cores, and parts ejection devices. These parts are generally made into general-purpose types. Mold companies need to be bigger and more refined, according to market demand, technology, and capital. , equipment and other conditions, determine product positioning and market positioning, these practices are especially worth learning and learning from small mold companies, and concentrate on gradually forming their own technical and product advantages. Therefore, my country's mold companies must actively strive to learn from the experience of these advanced foreign companies , for its better development in the future, the so-called deep hole processing is the hole whose length to hole diameter ratio is greater than 6. In general deep hole processing, the depth-to-diameter ratio L / d is greater than or equal to 100 in most cases, such as cylinder holes, The axial oil hole of the shaft, the hollow spindle hole and the hydraulic valve hole, etc., some of these holes require high machining accuracy and surface quality, and some of the processed materials have poor machinability, which often become a part of production. big problem

[0003] Extruded deep hole is a very common product process technology in cold and warm forging. In the prior art, the mold structure used in warm forging and extruded deep hole process has the following defects: 1. Only the stripper plate structure is used, and the punch is not cooled. The service life is very short; 2. The operator uses the original manual to cool the punch, so the production efficiency is low
