Technical Field

The invention relates to the field of high-speed rail roller processing, in particular to a blank conveying device of a high-speed rail roller cold heading forming machine and a pretreatment process before processing.

Background

The bearing is the most important, most critical and most core basic part in high-speed rail equipment, is known as the heart of equipment manufacture, directly determines the performance, quality and reliability of a high-speed rail host machine product, and the bearing industry is the national basic strategic industry and plays an important supporting role in national economic development and national defense modernization construction.

The development scale of the bearing industry in China is very large, but most products are concentrated at the low end. In the high-end bearing manufacturing field of high-speed rail, aviation and the like, China still has a considerable gap with developed countries. At present, bearings produced by domestic bearing enterprises can only meet the requirements of trains with the speed per hour of 150 plus 180 kilometers, and high-speed bearings in a few developed countries in Europe and America can meet the requirements of trains with the speed per hour of 350 plus 400 kilometers. For example, China already masters the high-speed motor train unit technology with independent intellectual property rights, but bearings matched with the high-speed motor train unit technology are all dependent on imports.

The roller is the most important component of the bearing and is also the most used rolling element in the bearing, wherein the roller is the most difficult product in the rolling element manufacturing technology, the quality of the roller directly influences the quality of the bearing, and the low technical quality level of the roller at the present stage is the main bottleneck restricting the development of the bearing industry. In order to break through the international monopoly of the high-speed rail bearing core technology and effectively fill the domestic manufacturing blank, the forceful star share is dedicated to the research and development of the special roller for the high-speed rail bearing, and the rollers for producing high-speed rail axle boxes, traction motors and gear box bearings ensure that the produced products have high reliability and strong impact resistance and dynamic load bearing capacity, and can meet the requirements of the running speed of the high-speed rail over 350 km/h and the running life of 300 kilometres.

Compared with the molding such as turning, hot heading, forging and the like, the cold heading process for roller molding has obvious quality advantages in the aspects of roller material density, fibrous texture, service life, strength and the like, and is a necessary process for high-quality roller molding. However, because the high-iron roller has larger size and higher quality requirement, general cold heading technical equipment cannot meet the production requirement, the advanced Japanese Korea CORPORATION (ASAHI SUNAC CORPORATION) AS-32-2 model double-station cold heading machine in the world is adopted for production, and the main contradiction is that the material with larger diameter adopts the cold shearing mode originally prepared by the cold heading machine, the end surface of the material section is seriously and roughly deformed, and the quality of the deformed and end surface burrs and the like after the cold heading roller is unqualified. In order to ensure the quality of the cold heading roller, the raw material section cannot be deformed and the end surface is smooth, the cutting technical equipment needs to be modified, a new processing technology is developed, and the cutting part originally matched with a cold heading machine is abandoned.

In the past, when a roller is machined, a coiled material or a long rod material is conveyed into a cold header through a matched conveying mechanism, the coiled material or the long rod material can be directly cut into sections through a cutter by a feeding mechanism in the cold header, such fractures have burrs and certain excess materials, the burrs or the excess materials cannot be integrated with a main body of a steel ingot blank during subsequent cold header machining, the quality problems of large girdle band, uneven end face and the like can be caused during the test process of a roller cold header blank, and the roller blank is subjected to soft grinding raceway surface and end face machining for reducing waste.
