我們擁有完整的轉向系統配件，例如轉向節、轉向油缸及修理包、襯套及軸承、轉向拉桿、手輪、喇叭及修理包、動力轉向馬達及油泵、中心銷及該系統的其它配件。Based on calculation method on unfold size and piece form, theory analysis and research are given on ellipse, circle tube, box as equal - high, irregular, unequal - high, irregular piece, process and condition on possibility of drawing are introduced, through calculation coefficient, number of drawing, drawing testing dies are made, results are given, it is similar to calculation method, in the same time, complex drawing presswork is planed, to avoid wrinkle, critical in drawing process. in this paper, die designing is introduced based on complex drawing unfold size calculation, press center is automatic calculated, apartments of press tools are calculated too with material mechanic production process and press form are better, period of die designing is to reduced, and cost of product is lower
對基於復雜拉深件展開尺寸計算的模具設計也作了詳細的論述，指出了現有復雜拉深件模具設計製造程序的不合理性，本文在復雜拉深件展開尺寸基礎上自動生成沖裁中心、沖裁周長，運用材料力學中桿件強度及抗失穩條件，實現對沖壓模具參數的自動計算，簡化了沖壓模具彈性元件、打料裝置的設計過程，給出了沖壓模具結構設計流程，使得模具材料核算，製造過程，沖壓方式更趨合理，縮短了模具設計製造周期，降低了產品生產成本。On jan 5 the physicians and pharmacists, accompanied by a local initiate who had just returned from banda aceh, carried the newly arrived medical supplies and some locally purchased tetanus vaccine and 220 kgs of medicine from the hong kong center. with help from the singapore air force, these items were efficiently flown to meulaboh and delivered to the ngo rescue coordination center and various red cross hospitals
元月5日，這十位福爾摩沙同修由一位剛從大亞市回來的同修陪同，在新加坡軍機的協助下，將原先帶來的藥品連同印尼同修在當地加購的破傷風桿菌疫苗和香港小中心送來的220公斤藥品，順利送達美拉莫meulaboh的ngo救援總協調中心與紅十字會醫院等。With prestressed rolling mill of the middle steelworks of taiyuan iron and steel limited group company as the researched object, this article analyze the existent questions and research the initial stress of prestressed rolling mill and computer control system, analyze the design thought of prestressed rolling mill and clarify the relationship between the dimensional precision of rolled material and the rigidity of base of rolling mill and the main method to increase the rigidity of base of rolling mill, analyze how to confirm the rigidity, sectional area of handle and post, and pretightening force, put forward the viewpoint that the key to assure great rigidity is to assure that the remnant initial stress is always positive during rolling, and develop intelligent control system with plc as the core on the basis of the former research to assure that the remnant initial stress is always positive during rolling
本文以太鋼集團公司中型型鋼廠預應力軋機為對象，分析了該廠預應力軋機所存在的問題，對預應力軋機的預應力以及微機控制進行了系統研究；分析了預應力軋機的設計思路，闡明了軋材尺寸精度與軋機機座剛度的關系及提高軋機機座剛度的主要途徑；分析了預應力軋機設計過程中預應力軋機的剛度、預緊拉桿和機架立柱斷面積及預緊力的確定；提出了預應力軋機保證高剛度的關鍵就是「確保軋制過程中，殘余預應力始終大於零」的觀點；在前述研究的基礎上開發了以可編程邏輯控制器為核心的智能監控系統，以確保「軋制過程中，殘余預應力始終大於零」這個要求。分享友人
