GD20 Rolling Shear Chamfering Machine on Small Metal Plate

A. Application and Characteristic of GD20 Rolling Shear Chamfering Machine:

1. Function: As a kind of compact and efficient welding support equipment, GD20 Hobbing Cutter Chamfering Machine aims on small metal plate welding groove preparation: It is used for small plate beveling, making preparation on subsequent welding operation:

2. Similar Function Machines: So, this equipment has similar function as Edge Milling Machine, and Triple Flame Cutting Machine, but in different working style, and aiming on smaller size of metal plate;

3. Applicable Workpiece: The GD20 machine is dedicated on small plate chamfering, on plate thickness equal to and or thinner than 20mm. The typical material of plate can be: Carbon steel, alloy, Stainless Steel, 16Mn, etc.;

4. Significance of Hobbing Cutter Beveling Machine:

1) This small equipment utilizes a pair of rolling shears as its acting unit on beveling the plate, convenient and highly efficient. It is a very cost effective machine tools on small plate edge milling for customer:

2) This machine fills vacancy in the field of small plate edge milling, providing versatile choices on solution of metal plate edge milling for customers to make decision.

B. Structure and Working Principle of GD20 Rolling Shear Beveling Machine:

1. The working principle of the machine please check below attached sketch and picture:

1) Indication on types of bevels on metal plate: (Fig.3)

2) Rolling shear working unit in Wuxi JACK GD20 model machine: (Fig.4)

2.  Structure of GD20 Small Plate Beveling Machine:

Lateral view on GD20 machine: (Fig.5)

1) The basic unit of GD20 is its main body, which is an integral frame of bed and trunk;

2) Working unit and manipulating unit are at the front side of main body, including rolling shear, angular ruler, four pieces of handwheels for different adjusting task (Plate thickness and others), the big and solid bottom supporting roller;

3) Control elements are integrated into back side, making the entire set of machine with compact structure and less bulky size;

3. Working Way in Small Plate Beveling Machine:

1) As can be seen from the above, there are a piece of rolling shear, equipped at working unit of the machine;

2) During work, with the going forward of the small metal plate through the working section, the small metal plate is squeezed and beveled in the process of rolling shear revolve, accomplishing on the task of small plate edge milling;

3) Plate Support: The entire piece of small plate is supported and sent forward with bracket along the machine, and operator carrying. Considering small size and light weight of small plate, there is no input and output conveyors:

The brackets alongside Wuxi JACK GD20 model machine: (Fig.6)

4. Working Velocity: The GD20 machine has safe, simple and convenient operation, and works in high efficiency, in the constant working velocity of 3000 mm cutting length/min.

C. Composition and Operation of GD20 Hobbing Cutter Chamfering Machine:

1. Main Units of Rolling Shear Chamfering Machine:

As can be seen from the attached photos and below, this machine is mainly composed of:

1) Stationary mechanical machine body;

2) Rolling shear inside operating cavity of machine main frame;

3) Input and output supporting racks of 3m long each: Holding small plate in the process of chamfering;

4) Electric control and operating system;

2. Operation on GD20 Small Plate Edge Milling Machine:

1) During work, the rolling shearing revolves under the drive of motor;

2) There is a cavity formed between the top milling cutter, and bottom transmission roller in the mechanical body. During operation, the small size plate moves through the cavity, got its edge beveled at the same time;

a) The 2 sets of top position handwheels above the rolling shear is for holding tightly the small plate during operation: (Fig.8)

b) The one set of bottom handwheel at left hand is for adjusting on vertical position of the bottom driving transmission roller, accommodating on various thickness of the small plate: (Fig.9)

c) To relieve hands of operator during operating the GD20 Rolling Shear Chamfering Machine, electric control is supplemented with foot pedal switch: (Fig.10)

3) There is an emergency stop button on the side wall of the machine, which is close at hand for convenient quick access, in case contingency happens.

D. Strong Points of GD20 Hobbing Cutter Beveling Machine:

1. This machine delivers finished product with correct size and clean surface of beveled edge;

2. Advantages of GD20 Small Plate Beveling Machine:

Compared with other metal plate beveling solutions, the use of GD20 features in:

1) Low power consumption;

2) High speed edge milling operation;

3) No need of follow up deburring operation;

4) Lower machine cost and compact size;

3. User Friendly Operation of GD20 Rolling Shear Beveling Machine:

1) Workpiece fit up step is not necessary;

2) Small plate beveling operation is of high efficiency;

3) Foot pedal switch, together with input and output workpiece rack, relieves tedious and cumbersome task of operator;

4) No limitation, or request on size of the workpiece, including both its length and width, for being edge milled in the GD20;

5) As summary, the efficiency on small plate beveling job in GD20 Small Plate Edge Milling Machine is far better than other way of plate chamfering. It is an ideal equipment in this field.
