Description

Technical Field

[0001] The present invention relates to the technical field of part powder cleaning, in particular to a metal part powder cleaning device and a using method thereof. Background Art

[0002] The interiors of some metal parts are usually designed with structures such as multiple curved small-diameter pipelines, dense inclined holes, dense blind holes, and complex cavities. Especially after the blank forming of complex metal 3D-printed structures, there are a large number of metal powders inside the metal parts. Moreover, due to these complex internal structures, it is very difficult to clean these residual metal powders.

[0003] Currently, for most small and medium-sized metal parts, manual powder cleaning is adopted. Manual powder cleaning is prone to improper operation, resulting in damage to the workpiece. And manual powder cleaning requires being in a dust environment for a long time. If not properly protected, inhaling dust will have a significant impact on one's own health. Manual powder cleaning needs to be carried out in an open environment, which easily causes the metal powder to be contaminated by oil and water in the air, resulting in an increase in the difficulty and cost of subsequent metal powder recovery. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings that for most existing small and medium-sized metal parts, manual powder cleaning is adopted. Manual powder cleaning is prone to improper operation, resulting in damage to the workpiece. And manual powder cleaning requires being in a dust environment for a long time. If not properly protected, inhaling dust will have a significant impact on one's own health. Manual powder cleaning needs to be carried out in an open environment, which easily causes the metal powder to be contaminated by oil and water in the air, resulting in an increase in the difficulty and cost of subsequent metal powder recovery, and to provide a metal part powder cleaning device and a using method thereof.

[0005] The purpose of the present invention is achieved through the following technical solutions: A metal part powder cleaning device includes a powder cleaning box. A collection box is installed at the bottom of the powder cleaning box. An installable box body that can be flipped is installed inside the powder cleaning box. A first motor is installed inside the installable box body. The power output end of the first motor extends outside the installable box body and is installed with a turntable. A vibration table is installed on the turntable. A clamping device and a vibration motor are installed on the vibration table. The clamping device includes a cylinder and a clamping block. The clamping block is installed at the telescopic end of the cylinder. A lifting rod is installed inside the powder cleaning box. The lifting rod is located on one side of the clamping device. A dust blowing gun and a dust suction gun are installed on the lifting rod. The vibration motor can vibrate the parts on the vibration table, so that the metal powder inside the parts is separated and falls off from the surface of the parts, so as to realize the separation and falling off of the residual powder in the narrow internal space. Then, the powder is cleaned by the dust blowing gun and the dust suction gun. The dust blowing gun and the dust suction gun generate a strong and swinging air flow, and drive the surrounding air to clean the residual metal powder inside the parts together.

[0006] A further technical solution is that two sets of slide rails symmetrical to the turntable are installed in the purifying box. Both ends of the lifting rod are slidably connected to the slide rails. A third motor is installed on the purifying box. The power output end of the third motor is connected to the lifting rod through a first crank and connecting rod. A swinging rod is installed on the lifting rod. A fourth motor is installed on the lifting rod. The power output end of the fourth motor is connected to the swinging rod through a second crank and connecting rod. The dust blowing gun and the dust suction gun are both installed on the swinging rod. By setting the cooperation of the lifting rod and the swinging rod, the dust blowing gun and the dust suction gun can be driven to lift and swing continuously to clean the clamped parts evenly. At the same time, the first motor can drive the turntable to rotate, improving the cleaning efficiency of the metal powder inside the clamped parts.

[0007] A further technical solution is that a second motor is installed on the purifying box. The power output end of the second motor extends into the purifying box and a rotating shaft is installed. The installation box body is installed in the middle of the rotating shaft.

[0008] A further technical solution is that an elastic layer is provided between the turntable (5) and the vibration table (6).

[0009] A further technical solution is that an inclined aggregate plate is installed between the purifying box and the collecting box.

[0010] A further technical solution is that a cabinet door is installed on the purifying box, and a transparent observation window is installed on the cabinet door. This device can automatically clean, remove powder and collect the clamped parts in the closed space of the purifying box and the collecting box, effectively saving manpower, reducing the threat of metal powder to the health of personnel, and at the same time isolating the metal powder from the external air, facilitating recycling.

[0011] A usage method of a metal part purifying device includes the following steps: S1, part fixing and clamping: Place the part to be purified on the vibration table, and clamp and fix the part through two sets of turntables on the vibration table; S2, vibration powder removal: The vibration motor on the vibration table generates vibration to vibrate the clamped part on the vibration table, so that the metal powder inside the part detaches from the surface of the part; S3, metal powder cleaning: The third motor drives the lifting rod to move up and down on the slide rail through the first crank and connecting rod, and the fourth motor drives the swinging rod to swing through the second crank and connecting rod. The dust blowing gun and the dust suction gun on the lifting rod and the swinging rod lift and swing to generate air flow to clean the metal powder on the part; S4, metal powder collection: The metal powder blown off during the S cleaning process will fall into the collecting box for collection; A further technical solution is that while the dust blowing gun and the dust suction gun on the lifting rod and the swinging rod in S3 lift and swing to generate air flow to clean the metal powder on the part, the first motor drives the turntable to rotate.

[0012] A further technical solution is that when collecting metal powder in S4, the second motor drives the turntable to flip through the rotating shaft to flip the part for cleaning.

[0013] The present invention has the following advantages: 1. The vibration motor of the present invention can vibrate the parts on the vibration table, so that the metal powder inside the parts is separated and shed from the surface of the parts, so that the residual powder in the narrow internal space can be separated and shed. Then, the powder is cleaned by the dust blowing gun and the dust suction gun. The dust blowing gun and the dust suction gun generate a strong and swinging air flow, and drive the surrounding air to clean the residual metal powder inside the parts together. By setting the lifting rod and the swinging rod to cooperate, the dust blowing gun and the dust suction gun can be driven to continue to lift and swing to evenly clean the clamped parts. At the same time, the first motor can drive the turntable to rotate, improving the cleaning efficiency of the metal powder inside the clamped parts. 2. This device can automatically clean, remove powder and collect the clamped parts in the closed space of the powder cleaning box and the collection box, effectively saving manpower, reducing the threat of metal powder to the health of personnel, and at the same time isolating the metal powder from the external air, which is convenient for recycling.
