3. Makina azida zamagetsi ndi magwiridwe antchito aukazitape wozungulira wazitsulo ndi ng’anjo yamoto

(1) Kapangidwe kazanja kawiri ka chimango cholipira, malaya apakati amalumikizidwa ndi gawo lokhazikika kupyola pakati, malaya apakati amatha kusinthidwa ndikuyika pang’ono, ndipo dzanja loyimitsa ndodo limalumikizidwa ndi pakati malaya ndi mabotolo, omwe amatha kuzungulira pang’onopang’ono mukamasintha reel, ndikuyiyika mukamalipira, Ndikosavuta kulumikiza mutu wa ndodo ndi mchira.

(2) chimango cha kasamalidwe ka waya Felemu yoyang’anira waya ndiyopendekera, ndipo cholinga chake ndikusintha mawonekedwe a ndodo ya ndodoyo kukhala ofanana kuti ateteze mawaya osokonezeka.

(3) Mawotchi amachotsa dzimbiri Makina ochotsa dzimbiri amakhala ndi magulu awiri a 2-degree obwereza kugubuduza. Yoyendetsedwa ndi mota-lifter-lead screw (kapena pneumatic), chosunthira chosunthira chimakankhidwa kuti chikukulitse kapena kubweza. Onetsetsani okwanira kupinda ngodya pakati kapamwamba ndi wodzigudubuza kupinda kuti peel pa lonse okusayidi ndi pazipita lapansi. Khungu la okusayidi litachotsedwa, limagwera mu thanki yosonkhanitsira pansipa kuti iyeretsedwe mosavuta. Dongosolo losindikizidwa kwathunthu limakhazikitsidwa kuti lithetse fumbi kuti lisapulumuke pamsonkhanowu.

(4) The PC steel rod concave thread forming of the drawing machine adopts the method of matching the drawing speed and the rotation speed of the mold. The mold is well stressed, the mold life is long, and the lead of the steel rod is artificially controlled to ensure the appearance quality of the product. The reducer of the wire drawing machine adopts a medium-hard tooth surface reducer, and there are protective devices at the tank body and the belt. The wire drawing tank is equipped with a shut-down pneumatic pinch roller to prevent the machine from shutting down and disordering the line. The diameter of the reel is 900mm, the maximum drawing speed is 100m/min, the wire drawing machine motor is 90KW, and the rotary die motor is 5.5KW.

(5) Makina owongoka Makina owongoka amangokhala ndipo amakhala ndi masanjidwe awiri opindikana omwe amapanga madigiri a 90 wina ndi mnzake. Pansi pa mphamvu ya thalakitala, imapanga zovuta ndikuwongolera chitsulo.

(6) Makina ochapira Makina ochapira amapangidwa ndi magulu awiri amiyala yazitsulo, yoyendetsedwa ndi mota, kuchotsa zinyalala pamwamba pa ndodo yachitsulo. Galimotoyo ndi 2KW, ndipo chowongolera chimachepetsa chopatsilira mosalekeza.

(7) There are two tractors. They are respectively placed in front of the quenching heating furnace, and after the tempering and cooling device, they play the role of full-line dragging. The traction machine is composed of three pairs of traction rollers, the lower roller is active and the upper roller is passive. The lower roller device is on the output of a non-standard transmission box with a single shaft input and three output shafts. The upper roller device is in the chute of the upper sliding frame. Keep to ensure the clamping force of the steel bar and ensure the smooth operation of the steel bar. The two tractors adopt micro-tension control technology, which can adjust the tension at any time according to the process needs and keep it between the two tractors. The micro-tension control technology can be used to adjust the tension and maintain at any time according to the process needs, which is automatic control between the two tractors. Under the formation of constant tension to provide guarantee to meet the needs of product quality. The traction roller is composed of two grooves, and the traction roller is arranged on the optical axis through an expansion sleeve to facilitate the replacement of the traction roller. The motor is 11KW, and the reducer is a planetary cycloid reducer.

(8) Kuzimitsa ndi kutentha kachipangizo Chida chotentha ndi kutentha chimapangidwa ndi chitsulo chosapanga dzimbiri, njira yoziziritsira ndikuzizira kwamadzi, ndipo kumapeto kwake kumakhala ndi chida chowombera mpweya. Thanki Kuthetsa ndi mamita 6 m’litali, ndi thanki tempering ndi mamita 5 m’litali

(9) Makina osinthira akumeta a hydraulic amatitsimikizira kudula ndi kusintha molingana ndi zofunikira zodula mwachangu mzere wopanga, kuwonetsetsa 100% kukameta ubweya, ndikuonetsetsa kuti ntchito yopanga ikupitilira. Njinga yamagetsi yamagetsi ndi 2.2KW.

(10) Makina onyamula adapangidwa molingana ndi zofunikira pakulipira kwa bala, komanso liwiro la kasinthidwe ka reel-take limasintha pafupipafupi ndi liwiro lazitsulo, pozindikira kulumikizana kwanthawi zonse. Njinga ndi 4kw, ndipo reducer ndi nyongolotsi zida zida.
