3. Mechanical equipment composition and technical performance of round steel quenching and tempering furnace

(1) Mfumo wa kupokezana wa mikono miwili ya fremu ya malipo, sleeve ya katikati imeunganishwa na safu iliyowekwa kwa njia ya kuzaa, sleeve ya katikati inaweza kuzungushwa na kuwekwa kidogo, na mkono wa kusimamishwa kwa fimbo ya waya umeunganishwa na kituo sleeve na bolts, ambayo inaweza kuzunguka kidogo wakati wa kubadilisha reel, na kuiweka wakati wa kulipa, Ni rahisi kuunganisha kichwa cha fimbo ya waya na mkia.

(2) Sura ya usimamizi wa waya Sura ya usimamizi wa waya ni muundo wa tapered, na kusudi lake ni kubadilisha sura ya pete ya fimbo ya waya kuwa sura ya mstari ili kuzuia waya zilizoharibika.

(3) Mechanical rust remover The mechanical rust remover consists of 2 sets of 90-degree repeated bending rollers. Driven by motor-lifter-lead screw (or pneumatic), the movable bending roller is pushed to extend or retract. Ensure sufficient bending angle between the steel bar and the bending roller to peel off the oxide scale to the maximum. After the oxide skin is peeled off, it falls into the collection tank below for easy cleaning. Fully sealed structure is adopted to prevent dust from escaping in the workshop.

(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) Mashine ya kunyoosha Mashine ya kunyoosha ni ya kupita na ina seti mbili za mistari ya kuinama inayounda digrii 90 kila mmoja. Chini ya nguvu ya trekta, hufanya mvutano kunyoosha na kunyoosha baa ya chuma.

(6) Mashine ya kuosha Mashine ya kuosha inaundwa na seti 2 za magurudumu ya waya za chuma, zinazoendeshwa na motor, kuondoa uchafu juu ya uso wa fimbo ya chuma. Pikipiki ni 0.55KW, na kipunguzaji ni kipunguzaji cha maambukizi inayoendelea kutofautiana.

(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) Kifaa cha kuzima na kupoza cha joto Kifaa cha kuzima na kukomesha joto hutengenezwa kwa sahani ya chuma cha pua, njia ya kupoza ni kupoza maji, na mwisho wa duka ina vifaa vya kupiga hewa. Tangi la kuzimisha lina urefu wa mita 6, na tanki ya hasira ina urefu wa mita 5

(9) Mashine ya kukata nywele ya kubatilisha inahakikishia kukata na kugeuza kulingana na mahitaji ya ukataji wa haraka wa laini ya uzalishaji, kuhakikisha ubadilishaji wa shear 100%, na kuhakikisha utendaji endelevu wa laini ya uzalishaji. Magari ya kituo cha majimaji ni 2.2KW.

(10) Mashine ya kuchukua imeundwa kulingana na mahitaji ya malipo ya baa ya chuma, na kasi ya kuzunguka kwa reel ya kuchukua hubadilika mara kwa mara na kasi ya kukimbia ya baa ya chuma, ikigundua wiring ya kawaida. Pikipiki ni 4kw, na kipunguzaji ni kipunguzaji cha gia ya minyoo.
