Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal processing, in particular to a deburring device for precision machining of forged castings and a machining method thereof. BACKGROUND

[0002] In the process of precision machining of forged castings, the forged castings need to be deburred, and one of the deburring methods is to use a shot blasting machine to throw high-speed impact cleaning shots to impact and clean the surface of the forged castings. A crawler-type shot blasting device is used to impact and clean the surface of the forged castings. The device is provided with rollers arranged in a triangular distribution in a box body, a crawler belt with holes and protrusions is sleeved on the rollers, and a circular protrusion is arranged on the side wall of the box body to extrude the crawler belt between the two rollers downward to form a recess. The forged castings are put into the recess, and the forged castings are driven to roll slowly in the recess by the rollers, and a shot blasting machine is arranged above the box body to throw cleaning shots to the forged castings rolling in the recess to deburr and clean the surface of the forged castings. At the same time, the cleaning shots fall through the holes on the crawler belt and finally leave the crawler belt to fall into the recycling area below.

[0003] In this process, the rolling of the accumulated forged castings depends entirely on the crawler belt and the protrusions on the crawler belt to drive the forged castings to lift and roll. This causes a large number of forged castings to be in contact with the impact of the cleaning shots for a long time, so the processing time needs to be prolonged to ensure that all the forged castings can obtain sufficient cleaning effect. At the same time, due to the accumulation of the forged castings, a large number of cleaning shots and cleaned metal scraps are blocked by the forged castings and mixed in the accumulated forged castings. A large number of cleaning shots and scraps are also easy to accumulate in the holes of the crawler belt, causing the holes to be blocked and unable to timely remove the cleaning shots and scraps from the accumulated forged castings, forming a protective layer and affecting the effect of the subsequent high-speed impact cleaning shots directly impacting the forged castings. After the cleaning shots leave the forged castings through the holes on the crawler belt, they will first fall to the part of the crawler belt below the recess, that is, the inner side of the crawler belt (the side directly contacting the forged castings is the outer side, and the side contacting the three rollers is the inner side), causing a large number of cleaning shots to spread on the inner side of the crawler belt. With the rolling of the crawler belt, the part of the crawler belt with the cleaning shots directly contacts the rollers, and the friction damage to the rollers is enhanced. SUMMARY

The receiving plate (20) is located in the inner space formed after the track (16) is sleeved on the power roller (12), rolling roller I (14) and rolling roller II (15), and is used to receive impurities falling from the cleaning tank.

6. The deburring equipment for precision machining of forgings and castings according to claim 5, characterized in that, The receiving plate (20) is divided into a short plate (201) and a long plate (202). The end of the short plate (201) away from the long plate (202) is close to the rolling roller I (14), and the end of the long plate (202) away from the short plate (201) is close to the rolling roller II (15), which is used to fully receive the impurities falling down from the cleaning tank.

7. The deburring equipment for precision machining of forgings and castings according to claim 6, characterized in that, A converging groove (21) is provided at the connection between the short disc (201) and the long disc (202). Two symmetrical discharge pipes (22) are fixedly connected to the bottom of the converging groove (21). The bottom opening of the discharge pipe (22) away from the converging groove (21) is not in the inner space formed by the track (16) and is used to discharge impurities in the receiving disc (20).

8. The deburring equipment for precision machining of forgings and castings according to claim 7, characterized in that, The rotating shaft (19) is sleeved inside the side box cover (2) to provide a fulcrum for the receiving disk (20) to swing. The two ends of the rolling roller II (15) are provided with annular grooves (151). A slider (23) is sleeved in the annular groove (151). A hinge block (24) is hinged to the end of the slider (23) away from the rolling roller II (15). The end of the hinge block (24) away from the rolling roller II (15) is hinged to the end of the long disk (202) close to the rolling roller II (15) to drive the receiving disk (20) to swing when the rolling roller II (15) changes position.

9. A processing method for a deburring device for precision machining of forgings and castings, using the deburring device for precision machining of forgings and castings as described in claim 8, characterized in that, The processing steps include the following: S1. Open the box door, put the forging casting into the cleaning tank, then close the box door, start the power assembly (10) and shot blasting machine (3), so that the shot blasting machine (3) can blast cleaning shot into the forging casting in the cleaning tank; S2. The power assembly (10) drives the power roller (12) to rotate, so that the teeth on the power roller (12) mesh with the tooth grooves on the track (16), and drive the track (16) to move cyclically on the power roller (12), rolling roller I (14) and rolling roller II (15), so that the track (16) lifts the forging casting in the cleaning tank, and drives the forging casting to be lifted in the direction of rolling roller I (14) to generate a flipping; S4. The power assembly (10) drives the extrusion block (18) to rotate. The elliptical surface of the extrusion block (18) will continuously extrude the track (16), causing the track (16) to deform and change the size of the hole at the deformation point of the track (16). At the same time, the track (16) will pull the rolling roller I (14) and the rolling roller II (15). Under the restriction of the sliding groove I (4), the rolling roller I (14) and the rolling roller II (15) under the restriction of the sliding groove II (5) will continuously change their current positions, causing the shape of the cleaning groove to continuously change, resulting in the position of the track (16) at the cleaning groove to continuously change, and the accumulated forging castings will be rolled in multiple directions. S5. The cleaning pellets and waste in the cleaning tank will fall into the receiving plate (20) through the holes on the track (16), and then roll into the collection tank (21) and be discharged through the discharge pipe (22). S6. The continuous change in the position of the rolling roller II (15) will drive the slider (23) to change its position through the annular groove (151), so that the slider (23) drives the receiving plate (20) through the hinge block (24) to swing around the rotating shaft (19) and change the angle and height at which the cleaning pellets and waste fall into the receiving plate (20), thereby impacting the cleaning pellets and waste adhering in the receiving plate (20); S7. The oscillating receiving plate (20) will intermittently impact the track (16), and in conjunction with the deformation of the track (16), remove the cleaning pellets and debris clogging the holes in the track (16).
