Abstract
The utility model discloses in a split type drift on hot heading machine, insert including punch holder, fastening bolt and drift, wherein, through three fastening bolt connection between punch holder and the drift is inserted, the locating pin is fixed and is inserted with the drift on the punch holder and be connected, and the purpose prevents to rotate relatively to arouse that the bolt leads to connecting failure by the shearing force. The straight opening of the punch insert and the punch seat are assembled by adopting the straight opening diameter to ensure error, the die is mainly under the action of impact load in use, the straight opening structure of the split die is only used for meeting the assembly precision, the contact area of the punch insert and the end surface of the punch seat is increased, the use strength requirement is ensured, the die structure and the manufacture are simple and easy, and the standardized manufacture is easy to realize; the punch insert has a refurbishment amount, so that the situation that after two refurbishments, the threaded hole penetrates through a cavity or the strength cannot meet the forging requirement is prevented.
Description
Technical Field
The utility model belongs to the technical field of gear machining.
Background
With the increasing demand of vehicles, the rapid development of vehicle technology is promoted; the multi-station hot forging equipment (hot header) is taken as a typical representative for mass production of the gear blank of the car gearbox, the production speed can reach 50-100 pieces, the gears in the passenger car gearbox are formed by multi-station hot forging, and the product is characterized in that: high precision and no flash. Due to the characteristic of hot forging forming, when the hot forging die is used for producing forging stocks of products by rapid hot forging equipment, the end surface of a punch in the die is repeatedly contacted with the high-temperature forging stock and cooling water, so that the thermal fatigue on the surface of the die is accelerated, and the service life of the die is limited. Due to abrasion of the hot forging punch die, the forming part cannot meet the product quality requirement, and the whole die needs to be scrapped, so that the die material is seriously wasted. The cost of the die remains a major factor affecting the profit of the product of the rapid hot forging apparatus.
Disclosure of Invention
In order to solve the problem, the utility model discloses a split type drift on hot heading machine, the technical scheme who adopts specifically as follows:
an upper split type punch of a hot header comprises a punch holder 1, fastening bolts 2 and a punch insert 3, wherein the punch holder 1 and the punch insert 3 are connected through the three fastening bolts 2,
the bolt further comprises a positioning pin 4, wherein the positioning pin 4 is fixed on the punch holder 1 and connected with the punch insert 3, and the purpose is to prevent relative rotation, so that the bolt is subjected to shearing force to cause connection failure.
The straight opening of the punch insert 3 and the punch seat 2 are assembled by adopting the straight opening diameter to ensure the error, the die is mainly under the action of impact load in use, the straight opening structure of the split die is only used for meeting the assembly precision, the contact area of the punch insert and the end surface of the punch seat is increased, the use strength requirement is ensured, the die structure and the manufacture are simple and easy, and the standardized manufacture is easy to realize;
the punch insert 3 is provided with a refurbishment amount, so that the situation that the threaded hole penetrates through the cavity after two refurbishments or the strength cannot meet the forging requirement is prevented.
The utility model has the advantages that:
the split structure is adopted, the integral structure is decomposed into a punch insert and punch seat structure, the punch insert is in contact forming with a hot forging blank, and the punch seat can be repeatedly used as a base body, so that the processing and manufacturing cost of the die can be obviously saved; the punch insert and the punch seat are positioned by straight openings to ensure the assembly relation and meet the requirement on forming strength, the fastening mode adopts bolt fastening, the pin holes are positioned to prevent rotation, the installation and the disassembly are convenient, the die change time is saved, and the production efficiency is improved.
