Description

В предлагаемом устройстве дл  сгибани  фасонных труб из листового материала применены небущие штампы подвижные станины, сдвигающиес  или раздвигающиес  под действием закрепленных на приводном валу эксцетриковых шайб. Дл  поддержани  заготовки во врем  сгибани  служат пластины, укрепл евхые одним концом к станинам под штампами.In the proposed device for bending shaped pipes made of sheet material, non-extrusive dies movable beds are used, which are shifted or moved apart under the action of eccentric washers fixed on the drive shaft. To support the workpiece during folding, plates are used, which are fixed at one end to the frame under the dies.

На чертеже фиг. 1 изображает вид устройства спереди; фиг. 2 - то же, вид сбоку; фиг. 3 - то же, внд со стороны маховика и эксцентриковых шайб; фиг. 4- то же, вид сверху; фиг. 5 - 8 - подготовленный дл  сгибани  труб материал; фиг. 9 и 10-готовые трзгбы.In FIG. 1 is a front view of the device; FIG. 2 - the same, side view; FIG. 3 - the same, vnd from the flywheel and eccentric washers; FIG. 4 - the same, top view; FIG. 5-8 - material prepared for bending the pipes; FIG. 9 and 10-ready triggers.

Устройство (фиг. 1 - 4) состоит из станка на двух ногах 1 и 1а, соединенных станиной 2 и снабженных снизу пластинами из плоского железа 3 и Т-образного 4; к последним прикреплены на шарннрах подвижные станины 5, несущие штампы. Между станинами 5 на подшипниках расположен приводной вал б, на обоих концах которого закреплены эксцентриковые шайбы 7, под действием которых сдвигаютс  и раздвигаютс  станины 5. На конце вала 6 закреплен маховик 8,  вл ющийс  в то же врем  и шкивом дл  ременной передачи. Четыре шатуна 9The device (Fig. 1-4) consists of a machine on two legs 1 and 1a, connected by a bed 2 and provided with bottom plates of flat iron 3 and T-shaped 4; to the latter are attached on the hinges movable bed 5, bearing stamps. Between the beds 5, a drive shaft b is located on the bearings, on both ends of which eccentric washers 7 are fastened, under the action of which the beds 5 are moved and moved. At the end of the shaft 6 a flywheel 8 is fixed, which is also a belt pulley. Four connecting rods 9

(фиг. 4) имеют с одного конца подшипник , соответствующнй эксцентриковой шайбе 7, а в другой - круглое отверстие. Эти шатуны св зывают эксцентриковые шайбы 7 с задними выступамн подвижиых станин 5 посредстврм наглухо вставленных в них болтов 10. При вращении вала 6 станины 5 начинают сдвигатьс  и раздвигатьс . Каждый шатун 9 состоит из двух половинок, соединенных муфтами 11, одна половина которых имеет правую винтовую нарезку, друга -левую. Эти муфты предназначаютс  дл  регулировани  степени сближени  станин 5. К последним в продольном нш1равленнн прикрепл ютс  стальные формы 12, имеющие полукруглую выемку, соответствующую наружному диаметру вырабатывемых труб. Эти формы 12 могут быть пр мыми или зигзагообразными. Дл  большей жесткости к станине 5 прикрепл ютс  перила 12а. Пустое пространство между формами 12 закрываетс  р дом стальных пластин 15, закрепленных в шахматном пор дке только одним концом к станннам 5 под штампами; другой же конец их скользит между формой 12 и рейкой 15а, так что во врем  работы кажда  половина пластин, прикрепленных к данной станине 5, т нетс  за ней (фиг. 1 - 3).(Fig. 4) have a bearing at one end, corresponding to an eccentric washer 7, and at the other end - a round hole. These connecting rods couple eccentric washers 7 to the rear protrusions of the moving beds 5 by means of bolts 10 tightly inserted into them. When the shaft 6 is rotated, the beds 5 begin to move and move apart. Each connecting rod 9 consists of two halves connected by sleeves 11, one half of which has a right-hand thread and the other is left-handed. These sleeves are designed to control the degree of convergence of the rolls 5. To the latter, steel forms 12 having a semicircular groove corresponding to the outer diameter of the pipes produced are attached in the longitudinal section of the elongated. These forms 12 may be straight or zigzag. For greater rigidity, railings 12a are attached to frame 5. The empty space between the molds 12 is closed by a series of steel plates 15 which are fastened in staggered order with only one end to the stannins 5 under the dies; the other end of them slides between the mold 12 and the batten 15a, so that during operation, each half of the plates attached to this frame 5 is nets behind it (Figures 1-3).
