Change the workin從麗g position of the selector sw秒紅itch to select automatic rolling,票內 foot mode rolling, and manual校微 mode.

Automatic circulation mode: S看行tart the hydrauli林車c motor, turn the s訊飛elector switch to auto紅村matic, and adjust the automatic訊去 feeding and rolling time and the backw術拍ard stop time according 離件to the hydraulic needs. At紅技 this time, the sliding seat perfor計都ms feed motion under the hydraulic pre很黑ssure controlle村拍d by the forward t計化ime relay, and the sliding se和小at performs backward stop moti匠藍on under the control o快讀f the backward stop time relay.東亮

II. When installing the thread文老 roller, the connecting wheel rods s員光hould be wiped clean離飛. When loading an年數d unloading the thread rolle商訊r, first remove the 睡制support seat of the術遠 wheel rod, install the thread在媽 roller on the wheel rod, and adjust 月購the thread roller to the required ax吃公ial position with the aid of an友志 adjusting washer. The end faces of件信 the two thread rollers sho熱化uld be adjusted to a horizontal 她刀plane as much as possible. The thread她一 roller and the support seat bearing a鄉門re combined with washers to prevent t草高he axial movement of the thread ro報南ller.

The support seat should be located at t新著he center of the workpiece. The positi坐爸on of the support seat n靜志eeds to change as the dia視鐵meter of the rolled workpiece cha很白nges. Adjustment method: Loosen t答水he two fixing bolts, move t制些he support seat to the desired po購如sition, and tighten the bolts.

The IV support block is installed on我吃 the support base, with the top end wel報懂ded with cemented 林科carbide. Loosen the fastening b愛器olts of the support block,話花 add or remove shims at the bottom of 文都the support block to adjust the heig個就ht of the support block, an高從d then tighten the b得能olts. The height of the sup拍坐port block plays an i日金mportant role in the rolling process.

(1) The height of 和朋the support block depends on th長冷e specification of t黑有he rolled workpi吧跳ece, and can be slightly h看關igher or lower de吃弟pending on the workpiece material. In看師 general, for ordinary s女作teel, high-quality carbon steel, 員少and nonferrous metal workpiece又可s, the center of the wor老歌kpiece can be slightly lowe離北r than the center of the r樂個oller rod by 0 to 0.25亮刀 mm, and for high-streng黑城th high-quality alloy steel, stainless頻動 steel workpieces, the center of 樹章the workpiece can be slig木資htly higher than the center o黑鐵f the roller rod. Users s船筆hould adjust accordi樂劇ng to actual conditions dur家山ing use.

(2) The width of the support block sho紙哥uld be based on the starting po書遠int that the thread roller wil這你l not collide w紅章ith the support block during rolli姐慢ng. For workpieces with a diameter of光媽 less than M10, the maximum allowable w遠國idth should be taken. For workpieces w讀機ith a diameter 匠費of more than M10,北玩 a larger width of the top end of the著綠 support block is allowed,明風 but it is not necessary to exceed 18m火很m.
