A valve plate micro bending machine

Abstract

The invention discloses a micro bending machine for a valve plate. The micro bending machine comprises a workbench, a motor, a left supporting plate and a right supporting plate, wherein the left supporting plate and the right supporting plate are vertically mounted on the workbench; an upper pressing shaft is horizontally mounted between the left supporting plate and the right supporting plate; a lower driving shaft and a lower driven shaft are arranged below the upper pressing shaft; the upper pressing shaft, the lower driving shaft and the lower driven shaft are distributed in an equilateral triangle manner; an upper pressing shaft gear and a lower driving shaft gear are arranged on the left side of the left supporting plate; the upper pressing shaft gear is connected with the left end of the upper pressing shaft; the lower driving shaft gear is connected with the left end of the lower driving shaft; the upper pressing shaft gear and the lower driving shaft gear are meshed with each other. Compared with the prior art, the micro bending machine has the advantages that the bending degree of the valve plate processed by the micro bending machine is proper, so that the micro bending machine is suitable for large-batch product production, and more than 35,000 pieces of products can be processed every day; the micro bending machine for the valve plate is extremely high in production efficiency.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a valve plate micro-bending machine. Background technique [0002] In order to ensure that the exhaust valve plate and the end face of the valve plate can be well sealed during the suction process of the refrigeration compressor to ensure that the refrigerant does not leak during exhaust, it is one of the better measures to improve the refrigeration efficiency of the refrigeration compressor. In this case, due to the rigid contact between the exhaust valve plate and the exhaust port of the valve plate, the flatness of the valve plate reed is too high, otherwise it is difficult to ensure its sealing requirements. The reed part is slightly bent to ensure that the end of the valve plate reed can be well sealed with the plane of the valve plate, so as to ensure that the valve plate can minimize the refrigerant leakage during the suction and exhaust process, but the valve plate...

[0002] In order to ensure that the exhaust valve plate and the end surface of the valve plate can be well sealed during the suction process of the refrigeration compressor, so as to ensure that the refrigerant does not leak when exhausting, it is one of the better measures to improve the refrigeration efficiency of the refrigeration compressor, but generally Under normal circumstances, because the exhaust valve plate is in rigid contact with the exhaust port of the valve plate, the flatness of the valve plate reed is too high, otherwise it is difficult to ensure its sealing requirements. The reed part is slightly bent to ensure that the end of the reed of the valve plate can be well sealed with the plane of the valve plate, so as to ensure that the refrigerant leakage of the valve plate can be minimized during the suction and exhaust process, but the valve tongue Due to the large amount of bending of the spring part, and the bending amount of the reed part is very small, generally only about 0.20-0.25mm, it is difficult to control the amount of bending during the bending process, and the amount of bending can be stably controlled by using a valve blade reed bending machine

[0003] The reed part of the valve plate of the existing refrigeration compressor is generally not bent. If the customer requires bending, the manufacturer can only bend it manually. The refrigeration efficiency is relatively poor, and the workload of manually bending the valve plate is too large. At the same time, the amount of bending cannot be controlled, and the quality cannot be guaranteed. It can also solve the problem that the reeds of a large number of valve products need to be bent
