1.Product description  

The RP deburring machine combines a dry sand belt with a universal roller brush. It is mainly used for deburring and chamfering the surfaces of various metal workpieces to improve their surface quality. This equipment integrates two functions: sand belt deburring and universal roller brush chamfering. It can complete multiple surface treatment processes in one stop, thereby enhancing production efficiency and the stability of product quality. It is applicable to stainless steel, aluminum alloy plates, iron plates, copper plates, etc. Different parameters can be adjusted and appropriate abrasives can be selected according to various processing requirements.

2.    Features

(1). Workpiece surface deburring treatment
This equipment is equipped with 1 set of wide sand belt mechanism. The sand belt rotates at high speed to remove burrs such as slag particles, scale, and large flanges on the workpiece surface.

(2). Deburring treatment for workpiece edges and holes
The equipment is equipped with 3 rows (2 sets per row) of universal roller brush structures. The roller brush abrasives rotate at high speed to scour the workpiece surface, making the contour edges around the surface and inside the holes smooth and rounded to achieve a fillet effect. It can comprehensively remove burrs generated during processes such as stamping, shearing, laser cutting, and plasma cutting in one go, ensuring all edges and holes of the workpiece achieve a small R-arc effect. The processing process is safe and reliable.

(3). Equipment conveyor belt
This equipment uses a high-damping rubber conveyor belt to transport workpieces, equipped with a vacuum adsorption platform and frequency conversion speed regulation. The conveyor belt material balances friction coefficient and hardness, meeting friction requirements while having a 50% longer service life than PVC.

(4). Equipment dust collection
The equipment is configured with a 3/5.5/7.5kW wet dust collector. Dust collection method: Most of the dust generated by the main machine during operation is effectively sucked away through the dust collection port, eliminating the hidden danger of dust explosion and keeping the inside of the equipment clean.

(5). Adsorption fan
The total pressure difference of the fan is up to 8500Pa, ensuring more stable workpiece adsorption and a long service life.

(6). Sand belt motor
It realizes real-time matching of sand belt speed and feeding speed, avoiding the risk of burning thin workpieces and truly achieving cold grinding. With high motor power, it makes product processing easier.

(7). Platform lifting motor
The platform lifting adopts a servo motor, featuring closed-loop control, fast response, and high precision. In contrast, stepper motors use open-loop control with slow response and low precision, resulting in a significant difference in effect when processing thin plates. The positioning accuracy reaches 0.01mm.

(8). Conveying platform
Following precision machining by a CNC gantry machining center and subsequent aging treatment, the flatness tolerance is controlled to within 0.02mm.

(9). Roller brush abrasives
Standard abrasives are adopted; the number of abrasive sheets is 12.5% more, the effective service length is 23% longer, and the overall service life is increased by 38.4%. Cogentech uses universal abrasives, which can be purchased externally.

(10). Conveyor belt cleaning
A standard cleaning brush is provided. Most of the dust on the conveyor belt is sucked away by the dust collector, with a small amount remaining on the belt. The cleaning roller can effectively remove the dust on the conveyor belt, which can be collected for regular cleaning.

(11). Adsorption cavity cleaning
Cogentech's independently developed adsorption cavity cleaning function realizes automatic cleaning of dust in the adsorption cavity, effectively preventing the risk of dust accumulation and explosion.

(12). Conductive slip ring
An industrial-grade conductive slip ring is standard, with a service life of 80 million revolutions, 5.33 times that of civil-grade ones, and a protection class of IP65.

(13). Alarm display
It has complete alarm and display functions.

Alarms include: safety door open, abrasive belt not tensioned, abrasive belt deviation, low pressure in adsorption chamber, roller brush abrasive replacement, motor overload, etc.

Displays include: abrasive belt current, safety door open, etc.

(14). Safety
It has a comprehensive anti-flying structure design. Anti-flying pressure rollers and anti-flying metal chains are installed at the inlet and outlet; all transparent windows are made of explosion-proof materials; the built-in lighting is an explosion-proof lamp.

(15). Abrasive wear compensation
Cogentech's independently developed automatic abrasive compensation technology reduces manual intervention, ensures uniform abrasive wear, and thus guarantees stable product quality.

(16). Control system
The equipment is equipped with a Delta high-definition touch screen, and the entire machine is centrally controlled by a PLC program, with comprehensive self-inspection functions, safety protection functions, and alarm functions.

3.    Mechanism principles:

(1). Principle of abrasive belt mechanism
The deburring mechanism of this equipment is a wide abrasive belt structure. The wide abrasive belt mechanism is arranged longitudinally and adopts our company's patented lifting and abrasive belt deflection mechanisms, which can easily perform high-precision wire drawing on the workpiece surface and handle hard burrs such as blanking and curling edges.

(2). Principle of roller brush mechanism
The R-angle chamfering mechanism of this equipment is a roller brush mechanism. Three rows of roller brushes in the mechanism are arranged in a staggered and cross-opposed manner. Driven by a revolving shaft, 6 roller brush abrasives rotate at high speed and beat the workpiece, enabling uniform grinding and chamfering of the workpiece at any position on the conveyor belt.

(3). Principle of fixing and conveying mechanism
The equipment is driven by a high-damping conveyor belt, with a frequency-variable adjustable conveying speed. Workpieces are firmly fixed on the conveyor belt through a combination of pressure roller clamping and high-negative-pressure fan adsorption.
