山東卷簾門敲擊彎曲的方法

Method of knocking and bending of Shandong rolling shutter door

制作卷簾門和生產銷商零件.都要把平直的型材或領料進行衍彎或卷田成所需的各種幾何形狀，而被擊型材或飯料是非常簡單的彎曲方法。

Make rolling shutter doors and manufacturer and distributor parts It is necessary to bend or roll the flat profile or picking material into various geometric shapes, and the beaten profile or rice material is a very simple bending method.

濟南卷簾門型材和飯料的彎曲.可采用冷彎和熱彎兩種方法。窗料和厚度在5mm以下的飯材，一般可采用冷彎，即在常溫下不用加熱進行彎曲。大型型材和厚度在5mm以上的飯材i則常要加熱彎曲。

Bending of Jinan roller shutter door profile and rice material Cold bending and hot bending can be used. Window materials and rice materials with a thickness of less than 5mm can generally be bent by cold bending, that is, bending without heating at room temperature. Large profiles and rice materials I with a thickness of more than 5mm are often heated and bent.

(1)工件彎直角:當工件的數量不多、尺寸不大時，可在臺虎鉗上進行。先將工件彎曲處進行劃線，然后把工{牛夾入臺虎鉗中，使線與鉗口對齊，夾縈鉗口.用錘敲打工件的4在那.逐漸使工件精彎曲線折成直角。

(1) Workpiece bending right angle: when the number of workpieces is small and the size is small, it can be carried out on the bench vice. Mark the bending part of the workpiece first, and then clamp the working {ox into the bench vice to align the line with the jaw and clamp the jaw. Knock the 4 of the workpiece there with a hammer. Gradually turn the fine bending curve of the workpiece into a right angle.

(2)卷簾門型材彎圓周:將經過矯直的型材置于鐵凳或墊塊上，1℃所要加工圓周的得要從頭尾依次進行均勻錘擊.使型材逐步從大小地彎曲成為所得耍的圓周。在對窗料等形狀比校復雜的型材穹閨時.型材一定要形狀做一襯塊.錘擊在襯塊上，一方面使幡擊力達到主筋之上，形成型材彎曲;另一方面保護型材表面槐角，免受錘擊損傷。

(2) Bending circumference of roller shutter door profile: place the straightened profile on the iron stool or cushion block. The circumference to be processed at 1 ℃ shall be hammered evenly from head to tail Gradually bend the profile from large to small into the resulting circumference. When calibrating the profile boudoir with complex shape such as window material The profile must be shaped as a lining block Hammering on the lining block, on the one hand, the strike force of the flag reaches above the main reinforcement to form the bending of the profile; On the other hand, protect the corners of the profile surface from hammering damage.

(3)卷簾門扭轉法:型材或扁條料暈扭曲變形時.可將工件穿入鐵路上專門用作扳扭的狹槽中或夾持在臺虎鉗上，用專用扳手將工{牛回扭，然后再放到平板上按扭曲角度線錘齒。撞擊行程由工件末端逐步向頂法推移.里面錘擊力要輕些，越向頂端錘擊力越要大些，也要正反兩面輪流進行矯正。

(3) Rolling shutter door torsion method: when the material halo of profile or flat strip is twisted and deformed The workpiece can be threaded into the slot specially used for wrenching on the railway or clamped on the bench vice, the working {ox can be twisted back with a special wrench, and then put on the flat plate to hammer the teeth according to the twist angle line. The impact stroke moves gradually from the end of the workpiece to the jacking method. The hammering force inside should be lighter, the hammering force towards the top should be greater, and the positive and negative sides should be corrected in turn.

如果型材有扭曲和彎曲同時存在.一般情況下，則應先矯正扭曲變形，然后再矯正彎曲變形。但如遇有過大彎曲變形時，則可先粗略地進行矯直，然后扳正扭曲.策后再精細地矯其彎曲。

If the profile is twisted and bent at the same time In general, the distortion shall be corrected first, and then the bending deformation shall be corrected. However, in case of excessive bending deformation, straighten roughly first, and then straighten and twist Then it is finely straightened until it is bent.
