Abstract

The invention discloses a high-temperature resistance element and a preparation method thereof. The top of a machining table is fixedly connected with a conveying belt and a top frame, the top of the top frame is fixedly connected with a stamping assembly, and the bottom of the stamping assembly penetrates through the top of the top frame and extends to the position below the top frame; the bottom end of a stamping rod of the stamping assembly is fixedly connected with a stamping block. According to the high-temperature resistance element and the preparation method thereof, which relate to the technical field of resistance, after the thin plate is conveyed below the stamping block, the stamping assembly is started to drive the stamping block to descend for stamping, during stamping, extrusion rods on the two sides extrude the two sides of the thin plate, and under the impact of counter-acting force, a connecting block is driven to stretch a reset spring to move upwards, and a workpiece generated by stamping slides and falls to a collecting frame along a discharging groove; during stamping, the two sides of the stamping part are extruded through the extrusion rods on the two sides, deformation of the stamping part caused by warping of the two sides is prevented, and the quality of a stamped finished product is improved.

Description

technical field [0001] The invention relates to the technical field of resistance, in particular to a high-temperature resistance element and a preparation method thereof. Background technique [0002] The high-temperature type resistor is a positive temperature coefficient thermistor based on a polymer conductive composite material. Before and after the critical transition temperature, the resistivity changes by several orders of magnitude, that is, the resistance of the PTC can vary with the ambient temperature of its use. As the temperature increases, the current can be reduced or cut off at a higher temperature to protect against over-current and over-temperature. At present, this type of device has been widely used in various circuit protection devices, such as lithium-ion batteries, automotive motors, etc. Wait. Generally, crystalline polymer composites filled with conductive particles can exhibit a positive temperature coefficient PTC phenomenon, that is to say, at l...
