Roll forming integrated technique of high intensity high-hardness alloy and roll forming equipment

高强度高硬度合金的轧锻一体化工艺及其轧锻设备

Abstract

本发明涉及高强度高硬度合金的轧锻一体化工艺及其轧锻设备,其工艺步骤主要包括:主机架与安装在其上的偏心轧辊沿着坯料的轴向作水平往复运动,偏心轧辊在此往复过程中不断重复着脱离坯料表面再落下锻打,随后滚压轧制坯料直至加工完毕。本发明用于高强度高硬度合金的轧锻设备由送料装置、主机架、出料装置和主机架驱动机构四部分配合组成。本发明的工艺简单实用高效,设备结构简单紧凑、在加工硬度HB值200以上的工具钢、轧辊钢、钨、钼、钽、铌难熔金属及其合金、钛合金等高强度、高硬度、难熔合金材料时能起到节约材料,提高成品机械性能的有益效果。
The invention relates to a roll forging integrated process of high-strength and high-hardness alloy and a piece of roll forging device thereof. The process mainly comprises the following processing steps: a main frame and an eccentric roller arranged on the main frame make an advance and return movement along the axial direction of the blank; the eccentric roller is continuously and repeatedly separated from the blank during the advance and return process, then falls down to forge, and rolls the blank until the processing is completed. The device for roll forging high-strength and high-hardness alloy consists of four parts, namely a feeding device, a main frame, a discharging device and a drive mechanism of the main frame. The process is simple, practical and efficient. The structure of the device is simple and compact. The process can save the material in the processing of the high-strength, high-hardness and refractory alloy materials with more than 200 HB, such as the refractory metal such as tool steel, roll steel, tungsten, molybdenum, tantalum, niobium, and alloy thereof, and titanium alloy, and improves the mechanical property of products.
