Method of teaching of gold of the Ban in metalworking exercitation is discussed

Lofting lofting is us according to blueprint paper the appearance of medium product and dimension undertake geometry spreads out and computation gives next makings measure. The geometry of the product spreads out, basically have the following kinds of commonly used kinds: (Does polyhedral spread out 1) : ? Is fast Gou Luo Xian able to bear or endure does  of my be an official cross the line does Ge blame those who shut cylinder of band  ?2) to spread out: ?  of alliance impossible talk in one's sleep calls instrument to be troubled by  short for Weihe River to lose cone of?3) of  of band of Niao of rice huller of Guo Weng Ba spread out: ?

After next material product geometry spread out, we return the makings below need general, and all affects these technology issues elements that involve in the following relevant working procedure undertake complete processing beforehand. After expect below even if spreading out through product geometry, according to the computation with corresponding formulary computation, come out next makings dimension computation, can undertake issueing material process. Is what should notice: ? Postscript illuminate the aluminous Qiong that fasten bursa subtles inclined admonish assist apricot of hydroxide of ⒓ of man of Mian of brown bear of  of  rancorring ⑵ not  scrupulously and respectfully instrument of Shang Wo of Yin of ㄓ of any of several hot spice plants of ⒊ Shang Wei seeks low-lyingponding abb pool to take ⒑ to add clever low-lyingponding lofty ⒑ mounds flag  of Mu Xia of establish flesh ⒉ . Next makings order ought to be abided by first big hind makings of small, reasonable platoon, cover the managing principle that checks next stuff. (2) craft of the makings below next makings craft basically has the following kinds of forms: (Expect below 1) plane shear, apply to the makings below thin stencil steel (basic ply 1 ― 5mm) . (Expect below 2) oxygen cut, apply to the makings below large board () of above of basic ply 10mm. (Expect below 3)Plasma Cutting machine, apply to the makings below stainless steel and nonferrous metal. (Water of 4) high pressure expects below cut machine tool, apply to the sensitive to heat data such as alloy of stainless steel, titanium. (5) line expects below cut machine tool, apply to the stuff with the mould that make and batch expensive claimed accuracy. (Expect below 6) punching machine, apply to big batch of thin stencil steel to shape next makings of the product. Craft of the makings below right choice can improve work efficiency, reduce manufacturing cost, save stuff, shorten production is periodic. (3) shape craft shapes craft basically has cold make, lukewarm make, the cent that heats up. What often apply is main have the following kinds of forms: (Is 1) folded pressure shape: ? Inspect Mei Yi " duty? is pressed through folding curved machine shape. Basically have: ? Strike out of?2) of Huan of a man's cap used in ancient times of cabin of stir-fry before stewing of ⑻ of Huan of a man's cap used in ancient times of admire of  of ⑺ of Huan of benzene admire a man's cap used in ancient times: ?

Inspect? of Mei Gao Jing to shape through soldering. (Does 4) hot-working shape: ? ? of Bi of the fish hawk that inspect intermediary through heating molten shapes. (4) assemble craft to assemble craft to basically have the following 3 parts. 1.

Assemble type cent for the factory, building site is assembled, the spot is assembled wait for 3 kinds. 2.

Measure include: (Does 1) measure the choice: of fundamental face? The dot that? of Mi goblet pa can regard fundamental basis as those, line, face choosing is fixed position fiducial it is very important. (Does 2) measure tool: ?

Ban metalworking is equipment is made, machining and in production of all sorts of machine equipment overhaul important with indispensable professional type of work, in other type of work cooperate closely to fall, the treatment that can complete all sorts of component and machine installation is made. 3, epilogue undergraduate is during metalworking exercitation, study Sheet Metal Fabrication puts in a suitable place to breed next makings → underline bore → to change the process of curved → plastics to horny → mediumly, in learning process of box of the iron that make, study operated plane shear, underline the labour such as the drilling machine of bore, table, punching machine, machine that fold a turn, measuring implement to provide reach device. To the undergraduate character, finished the training of basic work skill, accepted the education of basic idea style, developed field of vision, exercised courage, also rose to start work the ability that solves real problem, promoted the development of innovation ability, improved integrated quality at the same time, this is crucial, also achieved an undergraduate to undertake the ultimate goal in outline of metalworking exercitation education asks.
