Abstract

The utility model discloses sand blast equipment used for metal surface treatment, comprising a host machine [1] and a receiving sand separator [2]. Grinding fluid is jetted to the work piece surface at a high speed from a spray gun [18] through a grinding fluid pump [6] and a compressed air source [5] in order to achieve the purpose of finish and manufacture. The spray gun [18] is connected with an eccentric connecting rod mechanism [19] to make the eccentric connecting rod mechanism swing to and fro, enlarging the spraying angle. A stable and reliable rotation speed is controlled by a chain drive mechanism at the working bench [16], increasing the quality and the efficiency of the work piece surface treatment. A receiving sand separating box [3] is provided with an overall structure, with the separation of the floating oil and the water and the receiving sand sedimentation treatment are carried out in the same container, simplifying the structure and also reducing the manufacturing cost.

Description

Hydraulic abrasive blasting machine

A kind of abrasive blast equipment that is used for Treatment of Metal Surface.

The present invention improves on the basis of existing liquid sandblasting machine, and its operation principle is to be power with mill liquid pump and compressed air, will grind the liquid high velocity jet by spray gun and reach light to surface of the work and adorn the purpose of processing.This liquid sandblasting machine is made of the host work platform main frame, separator and receipts sand device three parts rotation obtains by the friction transmission, and this kind of drive makes the workbench rotary speed inhomogeneous, skid easily during work, thereby transmission efficiency is lower.In addition, the spray gun in the main frame is to adopt stationary structure, so it can't increase its jet angle, makes the workpiece projected area limited, thereby has influenced injection operating efficiency and surface of the work processing quality.Receive sand device and separator and be made up of two parts respectively, wherein receive the sand device and be made of whirl cylinder and long-pending sand jar, structure is comparatively complicated, and manufacturing cost is higher.In addition, the stirring of mill liquid in the main frame is by after the starting of mill liquid pump, through stirring nozzle the mill liquid in the liquid reserve tank is stirred, and this stirring means will increase the starting load of mill liquid pump, and reduce the service life of mill liquid pump.The work guard shield of sand-blasting machine is to adopt full-enclosed structure, and it is not too convenient to operate.

Task of the present invention is: it is reliable to design a kind of transmission performance, can increase the lance ejection angle again, and can improve mill liquid pump service life, simplifies complete machine structure, the hydraulic pressure sand-blasting machine of being convenient to operate.

The scheme of its solution is: rotatablely moving of sand-blasting machine workbench is to obtain more reliable and more stable rotating speed by a cover reducing gear and a pair of chain-drive mechanism.Increasing the method at its lance ejection angle, is to have adopted a cover eccentric rod gear control, and it can impel spray gun to make reciprocally swinging.The mill liquid mixture is that pneumatically stirs, and can obtain effect preferably.For simplifying complete machine structure, then will receive sand and be combined into one with separating two parts, it is received the sand method and adopts the precipitation method to carry out, and separating then of oil slick and water handled in same container, and oil slick fat is through a funnel it to be discharged outside the case.The work guard shield changes semi-enclosed structure into, is convenient to operation like this and observes trend of work.

Compared with the prior art the present invention has following advantage: the workbench velocity of rotation evenly, reliably, spray gun can be made reciprocally swinging, thereby has increased mill liquid jet angle, makes workpiece be penetrated enlarged areas, so both guarantee workpiece inject process quality, improved operating efficiency again greatly.After mill liquid adopts compressed air to stir, then alleviated the starting load of mill liquid pump, and improved the service life of mill liquid pump.After receiving sand and separating two parts and be combined into one, then simplified overall structure, improved anufacturability, reduced manufacturing cost.The work guard shield adopts semi-enclosed structure, will be convenient to workpiece loading and unloading and observe its trend of work.

Description of drawings:

Fig. 1: be the work system schematic diagram of hydraulic pressure sand-blasting machine.

Embodiment: accompanying drawings is as follows:

The hydraulic pressure sand-blasting machine is made up of main frame (1) and receipts sand separators (2), main frame (1) is to be power set with mill liquid pump (6) and compressed air source (5), be connected with spray gun (18) by two pipe-line systems, make mill liquid and compressed-air actuated mixture through the surface of spray gun (18) high velocity jet, to reach the purpose of light decorations processing to workpiece (17).Mill liquid is to prepare with the abrasive material of clear water and certain particle size to mix, and it is left in the fluid storage tank (7).Mill liquid in the fluid storage tank (7) stirs, and then at mill liquid pump (6) prestart, is connected with stirring nozzle (9) through pipeline with compressed air source (5) earlier, carries out jet stirring, so that mill liquid mixes.Spray gun (18) is to be connected with eccentric rod gear (19), when eccentric rod gear (19) turns round, drives spray gun (18) and makes relative reciprocally swinging, thereby strengthened jet angle, makes workpiece be penetrated enlarged areas.When spray gun (18) was made the high velocity jet workpiece, workbench (16) impelled workpiece (17) and spray gun (18) to relatively move again with 2 rev/mins speed of gyration.The gyration of workbench (16) is to obtain by chain-drive mechanism, it is by motor (11), decelerator (12) sprocket wheel (13), transmission main shaft (14), just can make workbench (16) do slowly rotation, workbench (16) is that a complete set of speed reduction gearing, support unit and fluid storage tank body are installed in the casing (8) by a cone axis bearing (10) and plain bearing housing (15) supporting.Mill liquid in the fluid storage tank (7) can be recycled, and it is to circulate additional by pump (23).Receiving sand separation case (3) is the integral solder structure, its oil slick and water separate, receive the sand precipitation process, all carry out in receiving sand separation case (3), the oil slick fat (20) in the fluid storage tank (7) overflows into through overflow pipe (21) and receives in the sand separation case (3), outside row's fat funnel (4) is discharged case.When needs are changed abrasive material, then open valve (22), will grind liquid pump and go into to receive in the sand separation case (3), by precipitate with separate after, can manually change.Workbench guard shield (24) is a semi-enclosed structure, and it promptly makes a gap slot outside 1/5th circumference places along workbench (16) are open in, so both be convenient to operate workpiece loading and unloading, is convenient to observe the trend of work of workpiece again.
