Four Roller Hydraulic Plate Rolling Machines CNC Sheet Bending

cone pole rolling machine/ shell bending machine

Performance:

This four rolls bending machine used to coil plate into different sharps such as

cylindrical form, conic form and arc, it adopted Japan hydraulic technical.
Top roll is main drive rolls, it can does vertical and level motion, up and down, parallel

translation is display. This machine include pre-bending function.

Structure:

This equipment composed of work frame, upper roll device, main drive device, down roll

device, side roll device, balance device, tuning device, hydraulic system, electricity control

system, NC system, lubricate device.
1. Work frame composed of based plate, fixed side frame and tuning frame, all parts

steel-welded. Two side frames fixed on the based plate by screw, and jointed together

by beams. The two side frames equip with upper roll and down roll moving rails, the fix

one have upper roll and down roll bearing housings.
2. The main drive device drive upper rolls do rotary movement. The two sides is support

by SP-1 sliding bearing. The drive side through keys, gear and main drive device.

The material of upper roll is 42Cr, heat treatment is HB220-280.
3. Main drive device
Composed of YZR motor, V type triangle belt, three class gear speed reducer, one set

open-gear.
4. Down roll device
Down roll is supported by aligning bearings, the bearing based in the rail of two side

frames.

The down side jointed with cylinder pistons. The bearing base can move up/down in the

railsunder hydraulic force. The adjustment of Pistons force controlled hydraulic system

pressure values according to the up/down rolls clamping force.
The support rolls were added on the bottom, bending precision will be increased in this way.

The material of down rolls is alloy head treatment HB220-280.
Side rolls device
Side rolls fit on the arc bearing base plate which fix on the two sides frame rails. The down

side jointed with cylinder pistons. The bearing base can move up/down in the rails under

hydraulic force. The adjustment of Pistons force controlled hydraulic system pressure values

according to the up/down rolls clamping force.
The material of side rolls is alloy head treatment HB220-280.
5. Tuning device
Composed of ram, bearing, tuning cylinder
6. Balance device
Composed of balance compact, screw
7. Lubricate device
Main speed reducer and side drive speed reducer adopted oil pool fly lubricate type, it is

cooled naturedly. When environment temperature is -10~0º C use N46 and N68, when

environment temperature is 0~40º C use N150 and N220, the other lubricate points adopted

oil gun to fill manually, working MEDIA is ZGN40-1 grease(winter ) and ZGN40-2 (summer),

two times for one shift.

Summarize:

This machine belongs to four roller plate rolling machine. It's for prebending and rolling of

barreused on pressure vessels and other industry. It has the ability of rough straightening

and round rolling as well.

The top roller is used as main drive. It's hydraulic driven. It drives the bottom roller and

side rollers through the friction between the plate and the roller, and thus to provide rolling

torque. The lifting of the bottom roller, the two side rollers, tilting frame, and the backup roller

is through hydraulic.

The pre-bending of plate end is achieve by lifting the bottom roller and clamping the plate

end,

meanwhile, inclined lifting the side rollers. The advantage of end plate bending (pre-bending)

and rolling can be conducted on the same machine.

his equipment composed of work frame, upper roll device, main drive device, down roll device,

side roll device, overturn device, hydraulic system (parts), electricity system (parts), and

lubricate device.

WUXI JINQIU MACHINERY CO.,LTD was founded in June 1969. it is located in No.99Qianluo road

Qianqiao town Huishan district Wuxi city. It is at Wuxi Vocation park. It mainly produces hydraulic press brake,

hydraulic shear, CNC sheet V grooving machine, allotype surface quick forming machine, CNC hydraulic turret

punching machine and other series products. It is one of the backbone enterprises in the domestic forging

industry with 40 years’ history.

The company covers an area of 62000 square meters with over 50000 square meters construction area.

It have advanced production equipments with imported large CNC gantry milling machine, imported large

CNC boring and milling machine, 100T carriageway and a series of iconic devices.

Company’s excellent design team can make personalized products according to the user’s demands which

to maximize customer value and optimize customer cost performance. Meanwhile, the company have always

stood in the forefront of technological innovation, continued to explore the “JQ”brand products widely and deeply,

and also attached great importance to the research cooperation. it has established long-term cooperative relations

with Jiangnan university, Nanjing university of Aeronautics and Astronautics, Jiangsu university, and also has set up

long-term stable cooperative relationship with the word’s leading multinational companies. Our hydraulic press brake

and shear machine have formed serialization

To met the customer’s different requirements.

Especially since 2002, the company has continued to increase investment in science and technology, our innovation

ability improves yearly through research staff’s innovation and hard work. We has received dozens of national invention

patents and utility model patents, won the provincial high tech enterprise in 2007, and obtained the innovation and reward

fund support from the national ministry of science and technology in 2011.

The company always adhere to quality system has access to the export product quality permit ISO 9000 international quality

system certification CE certification.

We sincerely hope to establish a close cooperation with domestic and foreign customers.
