A variety of shears, schoollevel machine, bending machine, rolling machine and other largescale processing equipment. These devices to improve the structural parts of the manufacturing capacity to provide a strong guarantee.在機(jī)械加工方面，本公司的設(shè)備加工能力在長垣地區(qū)可以說是領(lǐng)先的，我們有16米的落地銑鏜床，即將到廠的m=28，最大加工直徑φ3150的大型滾齒機(jī)和大型立式車床，數(shù)控重型臥式車床、各種臥式鏜床，立式銑加工中心等精、大、稀設(shè)備，為我們公司加工各種大型、高精度的零件提供了設(shè)備保證In mechanical processing, the processing capacity of the pany39。s equipment can be said in the Changyuan region39。s leading, we have 16 meters of floor milling and boring machine, uping visit to the factory m = 28, maximum machining diameter of φ3150 largescale and large vertical lathe hobbing machine , CNC heavy duty horizontal lathe, all kinds of horizontal boring machine, vertical machining centers, precision milling, large, rare equipment for our processing of all kinds of largescale, highprecision parts provided with equipment to ensure 機(jī)械產(chǎn)品生產(chǎn)過程是指從原材料到機(jī)械產(chǎn)品出廠的全部生產(chǎn)過程。它既包括：毛坯的制造、機(jī)械加工、熱處理、裝配、檢驗(yàn)、試車、油漆等主要生產(chǎn)過程；還包括包裝、運(yùn)輸?shù)容o助過程。其生產(chǎn)過程可以由一個工廠完成，也可以由多個工廠完成。我們公司除了大型結(jié)構(gòu)件，部分機(jī)械加工零件由本公司制造外，有一部分零部件由外協(xié)廠加工制造。主要是我們的生產(chǎn)能力不能滿足。Mechanical product refers to the production process from raw material to the entire machinery factory production process. It includes: blank manufacturing, machining, heat treatment, assembly, inspection, testing, painting and other major production process。 also includes the packaging, transportation and other auxiliary processes. Its production process can be pleted by a factory, you can also be pleted by a number of factories. In addition to our largescale structural parts, some machining parts manufactured by the pany, there are some parts from the outside coprocessing and manufacturing plants, mainly because our production capacity needs to be improved.下面就我們公司起重機(jī)生產(chǎn)的主要工藝流程作一介紹，在介紹工藝流程的同時，把每道工藝過程中所涉及到的設(shè)備作一些介紹，讓大家對我們的設(shè)備能力有一個初步了解。Now I39。ll briefly introduce process of making the crane, at the same time, you may have a preliminary understanding of our equipment. 先介紹起重機(jī)制造的總工藝流程，然后再逐一介紹每道工序的詳細(xì)情況。 我們的起重機(jī)由金屬結(jié)構(gòu)件、機(jī)加工件、外購件、外協(xié)件及電氣幾大部分組成，其工藝流程見工藝流程方框圖：起重機(jī)由金屬結(jié)構(gòu)件（主梁、端梁、平臺及梯子欄桿、小車架，等）、機(jī)加工件；外購件（軸承，緊固件，標(biāo)準(zhǔn)件等），外協(xié)件（因本公司設(shè)備或生產(chǎn)能力原因，委托外單位加工的零部件：如吊鉤）經(jīng)過裝配而成產(chǎn)品。Crane from the metal structure (the main beams, side beams, platform and ladder railings, small frame, etc.), machining parts。 purchased parts (bearings, fasteners, standard parts, etc.) and spare parts (due to our equipment or capacity reasons, the mission units processing ponents: If the hook) made through the assembled product.起重機(jī)工藝流程圖 金屬結(jié)構(gòu)件來料檢驗(yàn)化學(xué)成分、機(jī)械性能預(yù)處理噴丸噴底漆號料下 料數(shù)控、剪切、半自動切割 板料拼接埋弧自動焊探傷板料校平輥式校平機(jī)二次劃線下料自動切割組裝（點(diǎn)裝）氣保焊、手工焊 結(jié)構(gòu)參數(shù)檢查焊接探傷檢查超聲波裝配（匯裝）橋架、小車總裝檢驗(yàn) 機(jī)械加工件 （不經(jīng)熱處理毛 坯（鑄、鍛件）（焊接件）圓鋼件（鋸床下料）金屬切削加工車、銑、刨、磨、鏜鉆、插、拉、齒加工、熱處理（調(diào)質(zhì)、淬火、回火、正火）精加工部件裝配冷裝 熱裝車輪，臺車架，卷筒外購件電機(jī)、減速器、軸承、標(biāo)準(zhǔn)緊固件等外協(xié)件 非本廠加工的零部件 電器組裝 試車安裝發(fā)運(yùn)檢驗(yàn) 油漆 廠內(nèi)流程 出廠后流程一 結(jié)構(gòu)件生產(chǎn)工藝流程Production process for current each structure:：是指對進(jìn)廠的材料（包括鋼材及焊接材料），質(zhì)管部門檢查是否有制造廠的合格證明書，并根據(jù)其合格證明書按照國家標(biāo)準(zhǔn)及公司規(guī)定驗(yàn)收核準(zhǔn)，必要時要進(jìn)行復(fù)驗(yàn)，對其進(jìn)行化學(xué)成分和機(jī)械強(qiáng)度等項(xiàng)進(jìn)行抽樣檢查，是否達(dá)到國家標(biāo)準(zhǔn)和企業(yè)的有關(guān)要求；Inspection
