Embodiment 1

[0016] The present embodiment provides the processing method of the action bracket and the bushing, which is characterized in that it comprises the following steps:

[0017] (1) Apply lead powder to the graphite coating layer on one side of the bushing;

[0018] (2) Cut out the tip at the front end of the bushing;

[0019] (3) Apply glue on the other side of the bushing;

[0020] (4) Roll the bushing into a ring shape, and implant the graphite coating layer into the shaft nail hole of the shaft frame as the inner ring;

[0021] (5) The shaft frame assembly is soaked in the mixture of silicone oil emulsion and coconut oil stone alkali and placed for a period of time;

[0022] (6) After cutting the bushing, punch holes, and then cut the bushing twice;

[0023] (7) Place the shaft screw for one week after implantation;

[0024] (8) Pull out the pin.

Abstract

An action flange and bushing cloth processing method is characterized by comprising the steps of (1) applying lead powder to a graphite coating layer on one side of bushing cloth; (2) cutting the front end of the bushing cloth to form a tip; (3) applying glue to the other side of the bushing cloth; (4) rolling the bushing cloth in a ring shape, and placing the bushing cloth in a pin hole of a flange by using the graphite coating layer as an inner circle; (5) soaking a flange assembly in a mixed liquid of silicone oil emulsifier and coconut oil soap for a period of time; (6) cutting the bushingcloth, drilling, and cutting again the bushing cloth; (7) placing a pin inside for a week; (8) removing the pin. The action flange and bushing cloth processing method has the advantages that the leadpowder layer ensures smoothness of the bushing cloth; soaking in the mixed liquid of silicone oil emulsifier and coconut oil soap helps ensure that a lubricant is fully attached to the inside of thebushing cloth, the lubricant penetrates the bushing cloth after drying, and therefore lubrication degree of the bushing cloth and long-term lubrication stability are increased; double cutting of the bushing cloth helps ensure that chips from drilling are never left on the bushing cloth, unsmooth running of the flange due to the chips is avoided, and the pin has stable torsion; the closure part ofthe bushing cloth is opened to the flange so that stress bearing reliability is ensured for the bushing cloth.

Description

technical field [0001] The invention relates to the field of piano accessories, in particular to a processing method for a bushing of an upright piano action, and in particular to a processing method for an action shaft frame and a bushing. Background technique [0002] The shaft frame is the joint part in the action, and the hammer, linkage, and damper are all operated through the shaft nails in the shaft frame. Improving the quality of the shaft frame is a great guarantee for the quality of the action. The quality of the axle frame depends on the stability and lubrication of the bushing. It is especially important to improve the sensitivity of the shaft frame. It is difficult for the action bushing in the prior art to ensure the stability of long-term lubrication, and it is difficult to achieve that the shaft nail force is still controlled within the technical requirements after one million vibration tests. Contents of the invention [0003] The purpose of the present...
