Description

Technical Field

[0001] The utility model belongs to the technical field of spring processing equipment, and particularly relates to a micro spring chrome plating machine. Background Technique

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. Generally, it is made of spring steel. Springs are complex and diverse in types. Classified by shape, there are mainly helical springs, scroll springs, leaf springs, and special-shaped springs, etc. When some springs are produced and processed, chrome plating operations need to be performed on the springs, and at this time, spring chrome plating equipment is required.

[0003] After retrieval, the patent publication number CN217149360U discloses an environmental protection chrome plating device. The environmental protection chrome plating device includes a chrome plating tank. A vertical rod is arranged outside the chrome plating tank. A fixed frame is fixedly connected to the top of the vertical rod. A cylinder is fixedly connected to the bottom of the fixed frame. A piston rod of the cylinder is fixedly connected to a cover body. A suction fan is fixedly connected to the top of the fixed frame. One end of the suction fan is communicated with the top of the cover body. The other end of the suction fan is communicated with a box body. An air outlet pipe is communicated with one side of the box body. A gas purification component is arranged inside the box body. The gas purification component includes a filter screen, an activated carbon plate, and a cotton filter element, and the filter screen, the activated carbon plate, and the cotton filter element are sequentially clamped inside the box body. The environmental protection chrome plating device provided by the utility model solves the problems that chrome plating waste gas will damage the personnel and equipment in the chrome plating workshop, and at the same time, the waste gas discharged outdoors will also pollute the surrounding environment.

[0004] The chrome plating solution needs to be maintained at a certain temperature, and the temperature of the chrome plating solution needs to be controlled. The temperature of the chrome plating solution should be controlled between 50 °C and 60 °C, and the best is between 52 °C and 55 °C. When the chrome plating temperature is high, the chrome layer is soft. For every 1 °C decrease in temperature, the hardness will increase by 60 HV. However, in actual use, the existing spring chrome plating equipment cannot effectively maintain the temperature of the chrome plating solution between 52 °C and 55 °C, which affects the quality of the spring chrome plating layer. Therefore, we propose a micro spring chrome plating machine to solve the existing problems. Content of the Utility Model
