Product details

Our company has been specializing in the sales of lathe feeders for seven years, and we have been struggling all the way. Let's talk about our history. Firstly, looking back at the first oil film automatic bar feeder that was born in Taiwan in 2001, this product has high technological content, fast material changing speed, and convenient operation. Due to its high efficiency and cost-effectiveness, it has been increasingly relied upon by customers. In the operation of automatic bar feeding machines and lathes, it has become a unique force. Dongguan Beituo Electromechanical saw the importance of the future development of this product and sent a professional research and development team to Taiwan the following year to study. They also made a series of improvements to the original oil film automatic bar feeding machine, greatly reducing the high cost and making it more cost-effective. In 2011, Dongguan Beituo Electromechanical successfully produced the first oil bath feeding machine for smooth factory inspection. Stable function, high efficiency, low noise, strong stability, multiple modifications have been made to make the operation and use of the oil bath feeder very simple.

In recent years, due to the continuous increase in workers' wages, there has been an increase in operating costs and difficulty in recruiting workers for enterprises. This has forced enterprises to update and renovate equipment, improve the automation level of equipment, and thereby reduce labor costs. The oil bath feeding machine can be matched with various CNC lathes to complete automatic feeding work, greatly improving the work efficiency of CNC lathes, and is increasingly widely used at home and abroad.

CNC lathes are generally equipped with feeding machines such as oil bath feeding machines, storage feeding machines, and heavy hammer feeding machines. The storage type feeder has a large reserve of materials and can achieve continuous feeding without stopping the machine, but the price is relatively high; The heavy hammer feeder has a simple structure and is inexpensive, but it can only be used for processing parts with low precision requirements, and the noise and vibration are relatively high.

Oil bath feeding machine is a new product of feeding machine. Compared with the above two types of feeding machines, it has the advantages of a wide range of feeding diameters (generally ф 5~ф 42mm or larger), long feeding length (generally within 3 meters), easy operation, good stability, low noise, no wear and tear of bar materials, few operational failures, long service life, and moderate price. It is particularly suitable for processing high-speed, long bar materials, and precision workpieces, and has become a widely used feeding machine for CNC lathes.

We have made a series of technical improvements to further enhance the safety and reliability of the oil bath feeder, including the addition of a bidirectional filter device and the improvement of the hydraulic oil system; Installed hydraulic push rod rotating device, improved raw material conveying system, and so on. This solves the problem of hydraulic oil being easily mixed with foreign objects due to unclean processed materials, which can cause blockage of the oil pump and burn out the motor; And due to the long-term rotation of the processed material, the contact end between the push rod and the processed material is prone to deformation and jumping, which are common problems in oil bath feeders.

Therefore, the oil bath feeding function is widely used in various types of CNC lathes and has good development prospects.

2.1 Working principle

The oil bath feeding machine consists of five parts: hydraulic station, feeding tube, pushing rod, bracket, and control circuit. The principle is that the oil pump supplies oil to the feeding tube at a constant pressure (1 ≤ pressure ≤ 2KG), and pushes the piston rod (pushing rod) to push the bar material into the spindle, so it is also called an oil pressure feeding machine. When working, the rod material is in the hydraulic oil of the material tube. When the rod material rotates, it will float up from the material tube under the damping reaction stress of the oil. When the speed is fast, the rod material will automatically suspend in the center of the material tube and rotate. Greatly reduces the collision and friction between the rod material and the material tube wall. The vibration and noise during work are very small, especially suitable for high-speed, long bar, and precision workpiece processing. It is an increasingly widely used oil bath feeding machine both domestically and internationally, which can be matched with various processing machine tools to complete automatic feeding work. After the bar material is automatically fed, the machine tool is automatically in a waiting state and informs the operator of the feeding through a warning device.

2.2 Characteristics of the feeding machine
2.2.1 Seismic resistance

The damping reaction force of the oil causes the rod material to automatically suspend and rotate in the center of the material tube. Greatly reduces collisions and friction; Hydraulic power source, low working noise, and stable and smooth feeding action; The use of materials with different diameters in different material tubes results in a more reasonable gap between the materials and the tubes, making the feeding machine more stable.

2.2.2 Noise

The material selection for the material pipe is high-precision cold-rolled seamless steel pipe (with an error of less than 3 wires) combined with argon arc welding, with a smooth appearance, ensuring small deformation and high precision.

2.2.3 Leak resistance

The hydraulic part of the whole machine adopts PH taper connection method and high-pressure direct insertion connection.

2.2.4 Anti fouling properties

The use of gear pumps and oil filtration devices effectively increases the anti fouling ability of the machine body, greatly improving the service life of the machine body and hydraulic oil, and solving the problems caused by unclean raw materials.

Danger 1 may cause serious injury, please be extra careful!

★ Incorrect adjustments may cause feeder malfunctions and damage to the machine tool
★ Do not use any part of your body to come into contact with mechanical power devices while the equipment is in operation
Mechanical maintenance and upkeep can only be carried out in a stress free state after the power is turned off

1. Before starting the machine, it is necessary to check whether the overall condition is normal.
2. When the equipment is running, no one is allowed to do any other work on the machine.
3. Before starting up, it is necessary to connect the oil pipe and power supply. Before production debugging, the hydraulic system of the feeding machine must be turned on in advance to achieve the set pressure value.
4. The operator of this machine must be familiar with the operating rules of this machine, and unrelated personnel are not allowed to operate it.
5. The mechanical construction, circuits, and operating procedures of this machine cannot be modified without the consent of our company, otherwise our company will not be responsible.
6. The safety protection devices on the equipment are not allowed to be moved casually, nor are they allowed to be modified or intentionally rendered ineffective.
7. If the machine malfunctions during use, the stop button must be pressed and the main power switch must be turned off without error, and the cause must be quickly investigated. Only after troubleshooting can the device be turned on.
8. When there is a sudden power outage or abnormal accident, it is necessary to promptly remove the residual materials inside the barrel.
9. During the use of this machine, it is necessary to regularly maintain and inspect electrical components, wiring terminals, etc. to eliminate hidden dangers.
10. Maintenance requirements for the machine: Generally, it should be cleaned once every three months (it is recommended that customers clean it every two months).
11. Strictly control the appropriate amount of oil supply. If the oil supply is too small, the pressure, lubrication, and cooling effects will be poor, causing overheating of the feeding machine and increasing mechanical wear; It should be minimized as much as possible while ensuring pressure, lubrication, and cooling. Excessive oil supply can cause excessive pressure, which can seriously affect product quality and waste lubricating oil.
12. Before refueling or changing oil on a new or old machine after maintenance, the lubricating oil pipeline and oil tank must be cleaned thoroughly, and there must be no residual oil stains or impurities, especially iron filings. When refueling, fill the fuel tank according to the prescribed amount and use it repeatedly.
