Gate Grinding Device for Superalloy Castings

Abstract

The invention discloses a high-temperature alloy casting sprue grinding device which comprises a rack, first sand leather, second sand leather and a clamp. The rack is provided with a first polishing mechanism and a second polishing mechanism. The first sand leather is tensioned between a first rotating shaft and a second rotating shaft, and the second sand leather is tensioned between a third rotating shaft and a fourth rotating shaft. A push rod is arranged between the second sand leather and a conveying belt. A push plate is connected to the end, away from the first sand leather, of the push rod, and a first air bag abuts against the push rod. A first groove and a second groove are formed in the rack, the third rotating shaft is rotationally connected in the first groove, and the fourth rotating shaft is rotationally connected in the second groove. An upper push block abuts against the upper side of each of the third rotating shaft and the fourth rotating shaft, and a lower push block abuts against the lower side of each of the third rotating shaft and the fourth rotating shaft. Second air bags are connected between the upper push blocks and the rack, first elastic parts are connected between the lower push blocks and the rack, and the first air bag communicates with the second air bags. Compared with the prior art, the high-temperature alloy casting sprue grinding device is high in grinding efficiency and better in grinding quality.

Description

technical field [0001] The invention relates to the field of casting manufacturing, in particular to a gate grinding device for high-temperature alloy castings. Background technique [0002] After the casting is cast, redundant gates are inevitably produced. In the past, these gates were removed by turning on a lathe. However, for some high-temperature alloy castings, they are highly viscous and easy to stick to the knife, resulting in extremely poor cutting performance. , so that the life of the tool is very short, which increases the cost of production; in addition, due to the high viscosity of the alloy casting, it is difficult for the tool to form a smooth cut surface due to adhesion during cutting. [0003] For this reason, the patent document whose application number is CN201210147856.2 discloses a high-temperature alloy casting gate grinding device, including a clamp for clamping the casting, the lower part of the clamp is slidably connected to the first base, and one...

AI Technical Summary

Problems solved by technology

[0004] Although the above scheme uses sand skin instead of cutters to remove redundant gates, which reduces the cost and improves the smoothness of the casting gate surface, there are still the following problems: 1. This scheme uses clamps to clamp the casting, and the gate wears Over the receiving part, but the receiving part has a certain thickness. After the sand skin grinds the gate of the casting, because of the wall thickness of the receiving part, the gate on the casting cannot be completely ground, resulting in grinding The problem of incomplete cutting; 2. When the gate is ground in this scheme, one casting is placed in the receiving part and then ground, and the efficiency is very low.
