刮板输送机联接座类零件高效加工工艺研究

Research on Efficient Machining Process Method for Scraper Conveyor Connection Seat

摘要

刮板输送机是煤矿井下采煤机械中的关键设备之一，联接座类零件是刮板输送机的一个关键零件，主要用于刮板输送机的机头架和过渡槽等之间的连接，承受着井下采煤过程中的巨大负荷，随着公司采煤设备向大型化发展，为保证联接座类零件强度，需要采用锻件并经热处理调质后加工。目前来料毛坯均为四方自由锻件，毛坯加工量很大，每年加工数量多，加工完成后材料去除率多，采用加工中心加工较深的复杂型腔时，铣削刀具直径较小、悬伸长、刚性差、刀具振动大，存在加工效率较低、刀具寿命低等问题。单台机床每班加工数量少，严重影响生产进度，是生产的瓶颈问题，急需进行高效加工工艺研究解决。

Abstract

The scraper conveyor (hereinafter referred to as the scraper) is one of the most critical pieces of equipment in coal mining machinery, the connecting seat used in conjunction with the scraper conveyor is a key component. It is mainly used to connect various parts of the scraper conveyor and bears the enormous load the underground coal mining process. With the development of the company’s coal mining equipment towards larger sizes, in order to ensure the strength of the connecting seat parts, ings are used for processing and heat treatment is performed. Currently, the incoming materials are all square forging blanks, with large processing quantities and significant material removal rates processing is completed. When the machining center processes deeper and more complex cavities, the milling tool diameter is small, the overhang is long, and the rig is poor, leading to large tool vibrations, low processing efficiency, and short tool life. Each machine can only process a small number of parts per shift, severely production progress and becoming a bottleneck in production that urgently needs to be addressed.
