Cold heading forming process of filter resonance rod

Abstract

The invention discloses a cold heading forming process of a filter resonance rod. The cold heading forming process comprises the following steps: (1) mold shaping: a raw material is cut into sections, and the ends are shaped; (2) mold shaping: the head ends of semi-finished products in the step (1) are extruded to have upper cylindrical bodies and middle cylindrical bodies; (3) mold shaping: the middle parts of the outer end surfaces of the tail ends of semi-finished products in the step (2) are inwards extruded to form inner grooves; (4) mold drawing: the depths of the annular grooves are increased; (5) mold preforming; and (6) mold punching. The production process, provided by the invention, shortens the process steps of the prior art, reduces the waste of the raw material, and improves the processing efficiency.

Description

technical field [0001] The invention relates to a component resonance rod of a communication filter, in particular to a method for manufacturing the resonance rod by adopting a cold forging process. Background technique [0002] The resonant rod is a necessary part used in the base station equipment of aerospace radio and television communication, also known as vibrator, reflector rod, resonant vibrator, resonant column, etc. The existing rough machining process of the filter resonant rod is to use a straight bar material, which is cut by a punching machine, and the punching machine repeatedly squeezes the bar material to deform to obtain a resonant rod. The traditional production method has many defects, such as: 1. The energy consumption is large; the traditional processing method requires three punches to be formed separately three times, which increases the energy consumption. 2. The production efficiency is low. From the stamping production process, each machine can pr...

AI Technical Summary

Problems solved by technology

The traditional production method has many defects, such as: 1. Large energy consumption; the traditional processing method requires three punches to be formed separately three times, which increases the energy consumption

2. The production efficiency is low. From the stamping production process, each machine can produce up to 1900 pieces per shift. The equipment investment is large and the production capacity is low.

3. The loss of raw materials is large. At present, the weight of the blanks extruded by the punching machine is about 63g per piece. The raw material of the resonator rod is C14500 tellurium copper material, which is a new type of material at present. Among them, tellurium is a relatively scarce rare earth element, and the product blanks are very heavy. , the waste is very large, and it is a long-term loss of resources

4. The stability of product quality is poor. The stamping process is formed through multiple separate moldings. There is a certain degree of difficulty in the control of each process.
