Description

Technical Field

[0001] The utility model relates to the technical field of metal processing devices, in particular to a device for cleaning sand from the surface of metal parts. Background Art

[0002] Sandblasting is widely used in the surface treatment of metal parts. It is a mechanical surface treatment technology for metal parts. The sandblasting process mainly uses compressed air to spray metal sandblasting materials such as ceramic sand and iron sand onto the metal surface. The high-speed abrasive is used to remove rust, oxide layer and other contaminants on the surface of the workpiece. The sandblasting process can improve the appearance and smoothness of metal parts, and also increase the adhesion of coating, chrome plating or other surface treatment, and extend the service life of parts. After the sandblasting is completed, the sand cleaning device is needed to remove the residual sand on the metal parts.

[0003] Most of the existing metal parts surface sand cleaning operations are performed by closing the sand blasting machine sand valve after the sand blasting is completed, and only allowing compressed air to enter the sand blasting tube, so as to use compressed air to perform sand cleaning on the metal parts. However, due to the different structures and shapes of metal parts, there are many dead corners for sand cleaning when the metal parts surface is sand cleaned by compressed air alone, resulting in the accumulation of sand on the metal parts. When the metal parts are taken out for subsequent processing, the difficulty of subsequent processing of the metal parts is increased, and at the same time, it is easy to cause waste of sand.

[0025] Combined with Figure 1 To Attachment Figure 5 , a device for cleaning the surface of a metal part comprises a cleaning box 1, wherein two ends of the cleaning box 1 are respectively connected with a feed port 2 and a discharge port 3, wherein the feed port 2 and the discharge port 3 are both inclinedly arranged, and an air jet unit is arranged on the cleaning box 1, and a supporting spring 7 is arranged on the cleaning box 1, wherein the supporting spring 7 is provided with a plurality of groups, and a supporting inclined plate 8 is arranged on the supporting spring 7, and a positioning sleeve 9 is arranged on the supporting inclined plate 8, wherein the feed port 2 extends into a cleaning drum 11, and the positioning sleeve 9 is connected with the discharge port 3, and a cleaning drum 11 is rotatably arranged on the positioning sleeve 9, and a sieve hole 12 is arranged on the cleaning drum 11, and the sieve hole 12 is provided with a plurality of groups, and the sieve holes 12 are evenly distributed on the cleaning drum 11, and a driving rack 15 is arranged on the cleaning drum 11, and a positioning block 16 is arranged on the positioning sleeve 9, and a positioning gear 17 is rotatably arranged on the positioning block 16, and the positioning gear 17 is meshed with the driving rack 15, and a driving motor 18 is arranged on the positioning sleeve 9, and an output end of the driving motor 18 is connected with the positioning gear 17.

[0026] Through the above structure, the metal parts to be cleaned enter the sand cleaning drum 11 through the feed port 2, and the driving motor 18 drives the positioning gear 17 to rotate. Since the positioning gear 17 and the driving rack 15 are meshed with each other, the driving motor 18 can drive the sand cleaning drum 11 to rotate through the cooperation of the positioning gear 17 and the driving rack 15. The rotating sand cleaning drum 11 drives the metal parts to rotate, thereby reducing the dead angle of sand cleaning. Under the joint action of the jet unit, the sand cleaning operation of the metal parts is realized. Since the positioning sleeve 9 is arranged on the supporting inclined plate 8, and the sand cleaning drum 11 is rotatably connected to the positioning sleeve 9, the sand cleaning drum 11 is inclined, so that the metal parts can be driven to move toward the discharge port 3 while rotating, which is convenient for discharging after the sand cleaning is completed.

[0027] Combined with Figure 1 To Attachment Figure 4 The positioning sleeve 9 is provided with a material discharge trough 10, which penetrates the supporting inclined plate 8.
