Description

Apparatus for lining the part of a hydraulic pump with copper alloy}

The present invention relates to a lining apparatus for melting and welding a copper alloy at a predetermined position of a hydraulic cylinder block and valve plate (hereinafter, referred to as parts), and more specifically, only a copper alloy fixing portion of a hydraulic pump component. The gas generated during the combustion of carbon when heating parts made of carbon-containing metals such as cast iron or carburized steel is greatly reduced by heating the heating area with a high frequency heater by heating the correct position for a predetermined time. The amount of generation is minimized to minimize the occurrence of air bubbles in the lining part coated on the copper cladding, and the spacing between the high frequency induction coil and the parts is kept constant while the high frequency induction coil of the high frequency heater exactly matches the center point of the parts. The induction current is generated uniformly between the high frequency induction coil and the component, The present invention relates to a copper alloy fusion lining apparatus for hydraulic pump parts that can be uniformly heated in a short time to produce a high quality product quickly.

Conventionally, when copper alloy is melt-bonded to a predetermined position of a component such as a cylinder block and a valve plate for a hydraulic pump, it is a high frequency heater formed in a tubular shape in which an upper portion of a component such as a metal cylinder block and a valve plate is opened by hand. While inserting and heating to 900-1000 degreeC, the copper alloy is melt | dissolved in the other high frequency copper alloy melting furnace.

When the hydraulic pump parts are heated in a tubular high frequency heater in such a manner that the heating time is heated to 900 to 1000 ° C. while measuring the heating time as a timer, the hydraulic pump parts thus heated are heated in the high frequency heater. In the high frequency copper alloy melting furnace, the molten copper alloy melt is poured with a scoop-shaped tool and placed in the groove formed on the upper part of the hydraulic pump component, and naturally cooled after a certain period of time. Copper alloy fusion lining is completed.

These conventional working methods are all dependent on manual operation. When inserting a hydraulic pump component made of metal into a tubular high frequency heater, it is not inserted correctly to the inner center of the high frequency heater and is biased to one side. The temperature difference between the near side and the far side of the high frequency induction coil inside of the high frequency heater is generated, and when the copper alloy melt is poured later, a problem occurs that bubbles are generated in the copper alloy lining part due to poor melting of the copper alloy. do.

In addition, when contacting the high frequency induction coil on the inner surface of the high frequency heater in the process of inserting the metal hydraulic pump parts into the inside of the high frequency heater of the cylindrical type, a short circuit occurred and the high frequency heater was turned off. .

In addition, since the entire hydraulic pump parts are heated by heating the hydraulic pump parts inside the high frequency heater, the heating time is not only a problem, but also mainly cast iron or carburized steel. Since it is heating a part made of metal containing carbon, a large amount of gas is generated while carbon contained in the metal is burned in the process, and when a copper alloy melt is poured later, a large amount of bubbles is generated in the copper alloy lining part. Had a problem.

The present invention is to solve the above problems, the process of heating the parts at a high temperature by significantly reducing the heating area of the parts by heating only the copper cladding portion of the hydraulic pump parts for the correct time automatically The technical problem is to minimize the amount of gas generated in the air to minimize the occurrence of bubbles in the lining portion that is coated on the copper alloy deposit.

In addition, as the center point of the high frequency induction coil and the parts of the high frequency heater are exactly matched, the spacing between the high frequency induction coil and the parts is kept constant, so that an induction current is generated uniformly between the high frequency induction coil and the parts and thus, Another technical challenge is to be able to produce high quality products quickly by uniformly heating in a short time.

The present invention for achieving the above object, the primary workpiece sorting device for aligning a plurality of primary workpieces in a predetermined position, and the primary workpieces aligned in the primary workpiece sorting device is picked up and lowered on the center of the rotary plate of the workbench Gantry robot that picks up the secondary processed product with copper alloy melt on the primary processed product placed on the rotating plate and puts it on the settling platform, and moves up and down according to the height of the primary processed product and advances only when heating the upper surface of the primary processed product. The high frequency induction coil installed in the front and the high frequency induction coil and the primary processed product are maintained at regular intervals, and the high frequency heater that heats the upper surface of the primary processed product by the induced current generated from the high frequency induction coil, and the primary processed product is placed on the center of the upper surface. The rotating plate is characterized in that made of a workbench installed to rotate in accordance with the selected signal.

As described above, the copper alloy fusion lining apparatus of the hydraulic pump component according to the present invention has a high frequency by automatically heating the correct position for only a part of a predetermined time without heating the entire hydraulic pump component. When the heating area heated by the heater is greatly reduced to heat the parts made of carbon-containing metals such as cast iron or carburized steel, the amount of gas generated during the combustion of carbon is minimized, Minimizing the occurrence of bubbles in the lining portion has the effect of being able to produce high-quality parts.

In addition, as the center point of the high frequency induction coil and the parts of the high frequency heater are exactly matched, the spacing between the high frequency induction coil and the parts is kept constant, so that an induction current is generated uniformly between the high frequency induction coil and the parts and thus, The uniform heating in a short time has the effect of being able to quickly produce a good quality product.
