W12 Four roller plate bending rolls

The 4 roll plate bending machine is the easiest one, thanks to a frame designed to satisfy every kind of needs. Advantages are various :

★ Pre-bending is highly reduced because the material gets pinched by in between the two central rolls.

★ Working can be made in one only pass, following the steps here below:
1. Squaring
2. Pre-bending
3. Bending
4. Closing pre-bending

★ The plate is fed into the machine horizontally thanks to the support of the lower roll (B) with the side roll (D).

★ The plate is squared thanks to the position that the side roll (C) takes.

★ The space to the limit of the machine reduces to one side only, thanks to the possibility of squaring and bending in one only step.
We advise a 4 roll plate bending machine :

★ For a high and massive production

★ For the possibility to control by NC

★ For the possibility to make conical bendings

Structural characteristics

: Up roller device

The up roller gear drive from the main for turning, the ends of the SP-1 bearing support, drive-side through the flat key, off the main drive gear and connect the device to transfer torque, tip-side with the protection of Steel .

The material of the up roller is 42CrMo, heat hardening is HB220-300.

HRC 45-55

Ⅱ:Down roller device

Down roller supports under the bearing, the bearing housings on both sides of the rack mounted inside the track, the bottom of the piston and cylinder connected. Bearing in the liquid under pressure can rise and fall along the rail, according to the size of the thrust rod, steel plate under the roller clamping force required by the hydraulic system pressure control valve be adjusted. Addition of the down lower rollers can roll adjustment, improve the accuracy of product under the same material as the roll quality alloy steel 45#, heat treatment hardening is HB220-280. HRC 45-50

 

Ⅲ:Side roller device

Side of the roller bearing in the radial bearing pedestal, bearing on both sides of the rack mounted inside the track, the bottom of the piston and oil cylinder connected. Bearing in the liquid under pressure, can be tilted up and down along the rail, the size of the piston rod of the thrust force according to the needs of steel plate by the hydraulic system pressure control valve be adjusted. The side roll quality alloy steel 45#, heat treatment hardening is HB220-280. HRC 45-50

IV: Overturn device   

Overturn device through the oil cylinder , hinges torn off and driving overturned on a roller bearing aircraft overturned in order to remove products.

V:Cone device

Conical bendings with a conicity over 30 degrees reduce machine performances. This is due to the unbalanced load on the top roll and its bearings. The more is the cone tilting the more the machine performance will decrease, till a maximum of a 50% in length and in bending thickness.
