Forming machine for cavity filter input port coupling line and processing method of forming machine

Abstract

The invention discloses a forming machine for a cavity filter input port coupling line. The forming machine comprises a rotary table, a feeder, a forming cutter and a shearing cutter, the feeder is located on one side of the rotary table, the forming cutter and the shearing cutter are located on the other side of the rotary table, a rotary table center hole which is matched with the outer diameter of the cavity filter input port coupling line penetrates through the center of the rotary table, the rotary table center hole is matched with a conveying surface of the feeder, a clamping device is mounted on the rotary table, the clamping device clamps the cavity filter input port coupling line and enables the cavity filter input port coupling line to rotate with the rotary table, the forming cutter can bend the cavity filter input port coupling line, the shearing cutter can cut off the cavity filter input port coupling line, the forming machine further comprises a control device, and the control device is respectively connected with the rotary table, the forming cutter and the shearing cutter and coordinates the action sequence of the rotary table, the forming cutter and the shearing cutter. The forming machine has the advantages that the efficiency is high, the costs are low, and cavity filter input port coupling lines with different specification requirements can be manufactured.

Description

technical field [0001] The invention relates to the technical field of forming machines for coupling lines of electronic or communication products, in particular to a forming machine for coupling lines at input ports of cavity filters and a processing method thereof. Background technique [0002] When two unshielded transmission lines are close together, due to the interaction of the electromagnetic field of each transmission line, there can be power coupling between the transmission lines. This transmission line is called a coupled transmission line. Coupled lines are widely used in directional couplers, hybrid networks, filters, phase shifters, symmetric-asymmetric converters, matching networks, and various other useful circuits. Due to the coupling of electromagnetic fields, a pair of coupled lines can support two different transmission modes, which have different characteristic impedances. If the coupled lines are embedded in a homogeneous medium, the propagation veloci...

Problems solved by technology

Manual operation, poor dimensional consistency, inconvenient debugging after installation, low efficiency, many times of pulling copper strips, hooks are easy to break, only suitable for making samples, not suitable for mass production; making special fixtures, but different Different products and even the same product have different input port coupling lines. A lot of special fixtures are required before production, and the cost will be very high.
