Description

Technical Field

[0001] The invention relates to the technical field of copper tube production devices, and in particular to a wire pressing mechanism for a thin copper tube electroplating production line. Background Art

[0002] Thin copper tubes have strong tensile and corrosion resistance and are widely used in household appliances and various instruments. Since bare copper is easily oxidized, it is easy to affect the sensitivity and durability of the thermostat, so thin copper tubes usually need to be electroplated. Wire pressing usually refers to the process of fixing, pressing or adjusting the shape of the thin copper tubes before and after electroplating to ensure the smooth progress of the electroplating process and the stability of the electroplating quality. Appropriate pressing force helps to maintain stable contact between the thin copper tube and the electroplating solution, thereby making the electroplating layer more uniform. Too little pressing force may cause uneven distribution of the electroplating solution on the surface of the thin copper tube, while too much pressing force may damage the surface of the thin copper tube or affect the penetration of the electroplating solution. Therefore, how to adjust and preset the pressing force has become a technical problem that needs to be solved urgently in this field. Summary of the invention

The specific structure of each part is as follows: The pneumatic pressure assembly includes a pressure sensing airbag, a positioning pin, a sensing rod, a sensing sleeve, a limiting pin, a bearing support and an air pump, wherein the pressure sensing airbag is closely attached to the outer layer of the columnar cavity, the sensing rod is mounted on the pressure sensing airbag through the positioning pin, the sensing sleeve is sleeved on the sensing rod, a limiting pin is arranged on the sensing sleeve for limiting the sensing rod, and the air pump is connected to the sensing rod; the sensing sleeve is mounted on the top of the bearing support, and the air pump is arranged on one side of the bearing support; The auxiliary pressure assembly includes a support seat, a handle, a transmission rod, a transmission sleeve and a cotter pin.

One end of the transmission rod is tightly attached to the outer layer of the cylindrical cavity. The other end of the transmission rod is sleeved with a transmission sleeve. The cotter pin is installed on the transmission sleeve away from the handle end.

[0005] In the present invention, the bottom plate is a groove structure to ensure that the columnar cavity can move on the bottom plate after different pressing forces are applied thereto.

[0006] In the present invention, the shape of the pressure sensing airbag is the same as that of the cylindrical cavity, so as to facilitate fitting with the cylindrical cavity.

[0009] Beneficial effects: The present invention uses a pneumatic pressure component or an auxiliary pressure component to adjust and preset the clamping force of the cylindrical cavity where the thin copper tube is placed, so as to ensure that the applied clamping force is stable, thereby ensuring that the thin copper tube remains stable during the electroplating process, preventing it from moving or shaking due to liquid flow, rising bubbles or other external factors, thereby effectively improving the electroplating effect of the thin copper tube.

Three pneumatic pressure components 3 and three auxiliary pressure components 4 are arranged outside the columnar cavity 1. The pneumatic pressure component 3 or the auxiliary pressure component 4 applies a pressing force to the thin copper tube in the columnar cavity 1 to promote stable contact between the thin copper tube and the electroplating solution, so as to make the electroplating layer more uniform. The specific structures of each part are as follows: The pneumatic pressure assembly 3 includes a pressure sensing airbag 31, a positioning pin 32, a sensing rod 33, a sensing sleeve 34, a limiting pin 35, a bearing support 36, an air pump 37 and a reinforcing rib 38, wherein the pressure sensing airbag 31 is closely attached to the outer layer of the cylindrical cavity 1, the sensing rod 33 is mounted on the pressure sensing airbag 31 through the positioning pin 32, the sensing sleeve 34 is sleeved on the sensing rod 33, a limiting pin 35 is arranged on the sensing sleeve 34 for limiting the sensing rod 33, and the air pump 37 is connected to the sensing rod 33; the sensing sleeve 34 is mounted on the top of the bearing support 36, the air pump 37 is arranged on one side of the bearing support 36, and a reinforcing rib 38 is arranged on the other side of the bearing support 36; The auxiliary pressure assembly 4 includes a support seat 41, a handle 42, a transmission rod 43, a transmission sleeve 44 and a cotter pin 45.
