Abstract

The utility model relates to a high-temperature metal burr-removing device, comprising a burr-removing chamber, a combustion-gas mixing chamber and a seal-disc operating mechanism. The burr-removing chamber is communicated with the combustion-gas mixing chamber, the burr-removing chamber with metal parts is sealed by a control operating mechanism, and the mixed gas in the mixing chamber can be fired. The temperature in a closed cavity can rise 2500 to 3000 DEG C in a short time, and the burr and the flap edge on the parts can be removed. The utility model can remove the burr in a short time and have good removal effect, can remove the burr in a hole, and the metallurgical structure of the parts is not influenced.

Description

High temperature metal burr removing device

The utility model belongs to the metallic bur power equipment of removing.

At present, the residual burr that the removal machine components produce in process in the mechanical industry or the method for overlap are electrochemical method or mechanical means, the method more complicated that has, and the method efficient that has is lower, and some burr is not easy to remove.Therefore, be necessary to provide a kind of method and apparatus of removing burr.

The purpose of this utility model provides a kind of equipment of removing metallic bur power, and this equipment is easy to operate, speed is fast, effective.

For achieving the above object, the utility model adopts following structure: fuselage, the deburring chamber, gas mixing chamber and seal disc operating mechanism, there are two imports in described gas mixing chamber, one is fuel gas inlet A, another is oxygen intake B, their porch is adorned a check-valves respectively, on the mixing chamber that two kinds of gases mix, adorn a spark plug, the outlet of fuel gas mixer communicates with the deburring chamber, the fuel gas inlet of gas mixing chamber and the other end of oxygen intake respectively with combustion gas, oxygen cylinder communicates, cylinder is by Driven by Hydraulic Cylinder, described seal disc operating mechanism comprises: with two hinge bars of piston hinge, the other end of one of them hinge bar and another fixing point are hinged, and the other end of another hinge bar contacts with the seal disc of deburring chamber; Prevent the fore-set of pin joint displacement.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1: high temperature is removed the structural representation of metallic bur power equipment.

Among the figure, (6) be fuselage, (1) is the deburring chamber, (2) be workpiece, (9) be gas mixing chamber, it has two inlets, one is the fuel gas inlet, another is an oxygen intake, their porch is with a check-valves (10) respectively, adorns a petrol engine wide-range spark plug (8) on the mixing chamber that two kinds of gases mix, and gas mixing chamber's outlet communicates with the deburring chamber, the fuel gas inlet of gas mixing chamber and the other end of oxygen intake communicate with combustion gas, oxygen cylinder respectively, and cylinder is driven by hydraulic cylinder (11).The seal disc of deburring chamber (3) is by operating mechanism control, and operating mechanism comprises: with hinged two hinge bars of piston (14) (4 ') (4 "), (other end of 4 ") and another fixing point are hinged, and the other end of (4 ') contacts with seal disc; Also comprise the fore-set (13) that prevents the pin joint displacement.(5) are revolution garden workbench among the figure, are placed with a plurality of stand-by seal discs on the platform, and for driving the driving mechanism that revolution garden workbench rotates, it is made up of motor, decelerator (7), and (12) are hydraulic power unit.

The flow of combustion gas and oxygen is regulated respectively by valve, and for the different disposal material, the ratio of its oxygen and fuel gas (hydrogen, methane, natural gas etc.) sees Table 1.The stroke of regulator solution cylinder pressure (11) changes the indoor the blowing pressure of deburring, and the indoor the blowing pressure of required deburring sees Table 2 under the different materials.

Table 1

Table 2

Part material	The blowing pressure (MPa)
			Natural gas	Hydrogen
	Steel	0.8～3			1.5～5
Casting pig			0.5～2	1.5～3
	Zinc	0.3～1			0.5～1.5
Aluminium			0.5～1	0.7～1.5
	Brass	0.8～3			1.5～5

Method of operating: when the garden workbench rotates, just drive seal disc and workpiece and forward to below the deburring chamber, at this moment operating mechanism holds up seal disc and workpiece deburring chamber, the back seal disc that puts in place seals the deburring chamber, hydraulic cylinder is pressed into gas mixing chamber with fuel gas and oxygen, combustion gas mixes deburring chamber, back therein, fuel gas mixture check-valves action then, pipeline is sealed, light gaseous mixture, so at 20 milliseconds the utmost points in the short time, temperature in the closed chamber is raised to 2500～3000 ℃ suddenly, thereby relatively very big the part top surface area, and the relative very little part of volume is burr and overlap burn off.Because burning time is very short, the thermal capacity of combustion gas is limited, and the temperature rise of part own is very little, far is not enough to influence the metallographic structure of part.

Advantage of the present utility model: adopt this equipment, can remove burr and overlap in the short time at the utmost point, removal effect is good, can remove the hole inner burr, greatly increases work efficiency and product quality, and is applied widely.
