Main purpose and performance of the machine

1,This machine is a special equipment for processing all kinds of square ventilation exhaust pipes.It can process the plate thickness from 0.5mm to 1.2mm(Belowing photo just shows some typical kinds).

2,The machine is small, reset light, easy to move, easy to adjust, shoving simple and reliable, especially for industrial and mining enterprises, hotels, shopping malls ventilation exhaust pipe field processing use.

3,Use example diagram.

 

The structure of the lock forming machine

Lock forming machine mainly is composed of the trunk table, transmission and forming part and bending round head.

Note: 1, the machine side plate plus double stud (4) and disc spring (4a), the thickness of the plate can be self-regulation.

      2, the machine after passing the acceptance, according to the above figure to move the feed plate (1) or (2) can be. Normally, the four studs (3), (4) are not allowed to be adjusted

1, the trunk table:It is a welded shell.Welded by the angle steel and steel plate.(1), (2) and four pieces of lead-in positioning plate (see Fig. 2) are provided with a horizontal adjustment groove on the panel.

 

2,Transmission and forming

 

3.Bend round head

Bending round head is a special component mounted on top of the lock forming machine(as photo 2 part C).Used as the right angle of the fins.That is, fan-shaped plate solitary, the outer arc part bent into a certain height of the right angle side.With this fan-shaped right angle and" " shaped bone plate access flanging can be bent into angle pipe joints.(as photo 1, E=(1)+(6)

  Photo 4

The structural principle of the round head:(as the top photo 2),transmit by gear(5),(7),drive a pair of gears(10),The lower end of the gear is equipped with a reel(8) and(9),The workpiece through the rolling reel through, you can bend the fan-shaped plate at a certain height of the right angle bone.

Adjustment and use

1,The machine is formed by stacking method, can not be used for rolling machine, so the processing, the reel and the next reel must have a certain gap, the gap is about the model can roll the plate thickness plus 0.1-0.2mm. In addition to the factory before the tune, the user may not be free to turn the limit screw(3)and compression nut(4), butterfly spring(4a) (see Figure 2, Figure 5)

When the screw (3), nut (4) deformed back loose, or other causes of clearance changes,need to adjust, first loosen the nuts (4).Put the same thickness of a pair of blocks with the plate thickness+0.1-0.2mm slowly into the corner of the four pairs of the next rolling between the reel.Adjust the limit screw (3) so that the four corner rolls are substantially parallel.And then tighten the nut (4).If the minimum thickness of the model on the gap, then the sheet into the post, can be a little loose.Right-angle rolling reel 300 part, the tail roll reel plus disc spring can be manually adjusted to ensure that the thick plate reel "" bone fold enough to 90 °.

2,Bone shape adjustment(Photo 2)

The screw(1)or(2) on the registration plate is released and the position of the guide plate is moved in parallel along the groove,  the width or the width of the sheet to be controlled is changed. Will get different shaped bone.

3.Elbow use and adjustment(photo7)

First, the workpiece (fan-shaped sheet) - angle bent into 90 °,small piece length 15mm, height 8mm (as photo 6),and then the B end along (Figure 7) arrow direction along the guide(41), insert into the middle of reel (8)and(9).Pull the handle (42) toward the sector. Start the machine, forced the sheet in the direction of the arrow, along the guide sub-pressure to the rolling reel, after rolling reel can be formed.
