Sintering device for ceramic resistor production

Abstract

The invention discloses a sintering device for ceramic resistor production, which comprises an outer box, an inner box for ceramic resistor sintering is fixedly connected in the outer box, a closing door is hinged on the outer box, a sealing part is mounted on the closing door, the sealing part comprises an air bag and a sealing block, the sealing block is fixedly connected on the closing door, and the air bag is connected with the sealing block. The sealing door is provided with a groove, the air bag is fixedly connected in the groove, the sealing component is used for sealing the inner box, a fixing component is installed between the outer box and the sealing door, and the fixing component comprises an installation cavity, a lantern ring, a sliding block and a trapezoidal block. And a second spring is compressed, at the moment, a sliding rod can convey air in a sealing cavity into an air bag through an air conveying pipe, and when the air bag is inflated, the size of the air bag is increased, so that the air bag is attached to the side wall of the outer box, and a better sealing effect is achieved on work of the inward ceramic resistor piece.

Description

technical field [0001] The invention relates to the technical field of ceramic resistor production, in particular to a sintering device for ceramic resistor production. Background technique [0002] Since the columnar resistors used in ceramic resistors are solid resistors formed by mixing conductive substances such as Sn0 and insulating ceramics such as talc, Ca compounds, and Ba compounds, and sintering at a high temperature above 1000C, due to this Compared with thin film resistors, they can be used at high temperatures, have excellent chemical resistance, weather resistance, and are less prone to disconnection, so they are suitable for resistors for high-voltage circuits or power circuits. [0003] Most of the existing sintering devices for the production of ceramic resistors use a fixed plugging method to seal the sintering processing space, which leads to greater wear and tear when used for a long time, making the sealing effect poor, thus affecting the sintering of ce...
