Of craft of treatment of casing of gearshift of ZL50 fork-lift truck improve

1 production cycle is long, machine effect to lead craft of low primary treatment to use current device, production is periodic and longer, use at small lot production only. Current equipment is general versatility is good, but treatment efficiency is low. When former technology milling machines a face, need to search by the line, chase treatment, one can machine 15 only. Although machining center machines quality taller but treatment efficiency is not tall, 3 machining center can machine 24 two classes only everyday, especially boring machine needs to search with boring pattern plate, chase Kong Jia to be versed in. Drilling machine needs to underline, search, individual Kong Jia is versed in, handling time is long, efficiency is lower. A day two 16 hours can machine 20 ～ only 24 casing, and our daily output that assemble a car 32, already cannot satisfy manufacturing need. Outside needing assist gear-box assembly is covered 10 times / or so days, make truckload cost raises. 1.

Working procedure of the finish machining in craft of highland of 2 finished cost undertakes in machining center for the most part. Machining center finished cost should compare ～ of common device second year in high school 3 times, use an entrance especially special cutting tool, should compare country tower above of price of common cutting tool is decuple much, equipment upkeep costs is higher also. So machining center suits to be produced at trial-produce or small lot only, or the working procedure that common device machines hard. The advantage new technology of 2 new technology uses primary facility and band of private plane photograph, make full use of already primary facility, use private plane to improve treatment again efficiency, raise yield. Thick milling foreword cancels to underline working procedure formerly, use tool fixed position, clamp, use X2010C Long Menxi to machine, aperture of Ⅴ of ～ of Ⅰ of boring of aperture of Ⅴ of ～ of Ⅰ of each face, thick boring, essence uses mill of essence of life private plane treatment, each aperture treatment compares take time inside T6 face, use the method that establishs car and tie of photograph of private plane treatment to improve process capability, each aperture uses T6 and T1 face, T2 face and T2 face respectively a group opposite group auger auger, attack, the aperture that the others face and private plane cannot machine is gotten with Z35, attack. Is new technology line as follows: ? → of car of → of boring of essence of → of thick boring of → of? of  of field of obstruct field  is gotten, attack → to get, attack. After using new technology, leave out underlines working procedure, need not machining center, mill face, bore hole, face of T6 of bore, tap, car increased private plane, improved work efficiency, reduced cost. Amount of aggregate of the equipment after craft is improved reduces 3, the number reduces 6 people, treatment yield rises 2.

4 times. Gear-box assembly is OK and whole oneself are assembled, outside assembling cost to be able to be compared assist gear-box assembly reduces cost 1000 yuan / stage left and right sides. After craft is improved, replace next equipment, use at new product development and trial-produce, increase the competitive capacity of the enterprise thereby. Improve through craft, take the lead in using private plane to machine in course of study of domestic person of the same trade, improved manufacturing efficiency, reduced cost, enhanced industry vitality and competitive ability.
