起重机制造的工艺流程Crane manufacturing process我们公司主要生产桥、门式起重机，具有自行设计、研制能力和制造加工能力；我们的产品涉及到冶金、水工、电站、化工、造纸、造船、航空、航天、港口等行业，目前制造的起重机最大起重量为500t，最大起升高度达400米。
Our company mainly produces bridge, gantry crane, with our own design, development capabilities, manufacturing and processing capacity; of our products related to metallurgy, hydraulic, power, chemical industry, papermaking, shipbuilding, aviation, space, ports and other industries, the current manufacturing maximum starting weight of the crane 500t, maximum lifting height of up to 400 meters.在结构件制造方面，本公司具有较强的制造能力；有年处理能力达5万吨以上，具开卷、校平、剪切、抛丸、喷漆、烘干能力的预处理生产线一条；有数控切割设备5台；（6000X50000）；半自动切割60多台，CO2气体保护焊，埋弧自动焊（平、角焊）200多台；其他焊机300多台。
有各种剪板机，校平机、折弯机、卷板机等各种大型加工设备。
这些设备为提高结构件的制造能力提供了有力的保证。
In the structural parts manufacturing, our company has strong manufacturing capacity; have capacity of more than 5 million tons in a year, with open-book, school level, shearing, shot blasting, painting, drying capacity of a pre-processing production line; a numerical cutting equipment 5 sets; semi-automatic cutting more than 60 units, CO2 gas shielded welding, submerged arc welding (flat, angle welding) more than 200 units; other welding more than 300 units. A variety of shears, school-level machine, bending machine, rolling machine and other large-scale processing equipment. These devices to improve the structural parts of the manufacturing capacity to provide a strong guarantee.在机械加工方面，本公司的设备加工能力在长垣地区可以说是领先的，我们有16米的落地铣镗床，即将到厂的m=28，最大加工直径φ3150的大型滚齿机和大型立式车床，数控重型卧式车床、各种卧式镗床，立式铣加工中心等精、大、稀设备，为我们公司加工各种大型、高精度的零件提供了设备保证In mechanical processing, the processing capacity of the company's equipment can besaid in the Changyuan region's leading, we have 16 meters of floor milling and boring machine, upcoming visit to the factory m = 28, maximum machining diameter of φ3150 large-scale 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 large-scale, high-precision parts provided with equipment to ensure机械产品生产过程是指从原材料到机械产品出厂的全部生产过程。
它既包括：毛坯的制造、机械加工、热处理、装配、检验、试车、油漆等主要生产过程；还包括包装、运输等辅助过程。
其生产过程可以由一个工厂完成，也可以由多个工厂完成。
我们公司除了大型结构件，部分机械加工零件由本公司制造外，有一部分零部件由外协厂加工制造。
主要是我们的生产能力不能满足。
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 completed by a factory, you can also be completed by a number of factories. In addition to our large-scale structural parts, some machining parts manufactured by the company, there are some parts from the outside co-processing and manufacturing plants, mainly because our production capacity needs to be improved.下面就我们公司起重机生产的主要工艺流程作一介绍，在介绍工艺流程的同时，把每道工艺过程中所涉及到的设备作一些介绍，让大家对我们的设备能力有一个初步了解。
Now I'll briefly introduce process of making the crane, at the same time, you may have a preliminary understanding of our equipment.先介绍起重机制造的总工艺流程，然后再逐一介绍每道工序的详细情况。
我们的起重机由金属结构件、机加工件、外购件、外协件及电气几大部分组成，其工艺流程见工艺流程方框图：起重机由金属结构件（主梁、端梁、平台及梯子栏杆、小车架，等）、机加工件；外购件（轴承，紧固件，标准件等），外协件（因本公司设备或生产能力原因，委托外单位加工的零部件：如吊钩）经过装配而成产品。
