Problems solved by technology

[0003] The structure of the loudspeaker generally includes a bracket, a magnet, a pot frame, a fixed core support piece, a cone-shaped paper cone, etc. Among them, the pot frame is generally made of steel or aluminum, and its requirements are firm and does not resonate with the sound of the audio equipment. At this stage, the processing technology of the pot frame is mainly obtained by forming and stamping a single piece of raw material at one time. This processing technology has the problems of low dimensional control accuracy and high defective rate, especially in the pot frame. For more delicate components such as ear flowers and ear holes, the traditional process cannot be realized. More importantly, the punching of the ear holes is also very difficult because they are on an inclined plane.

Embodiment 1

[0024] Such as Figure 1 to Figure 3 Shown, a kind of processing technology of the loudspeaker basin frame with horizontal ear hole, comprises the following steps:

[0025] Step 1: cutting, be 0.8 millimeter in thickness by shearing machine, cut out a square raw material that side length is 182 millimeters on the roll material that width is 182 millimeters;

[0026] Step 2: Blanking, punching out a circular blank with a diameter of 180 mm on the square raw material through the blanking die; the diameter of the punching pin of the blanking die is 180 mm;

[0027] Step 3: Punch the positioning hole, and punch a positioning hole with a diameter of 20 mm in the center of the circular blank through the punching positioning hole die;

[0028] Step 4: stretching, punching out a bowl-shaped semi-finished product on the circular blank with positioning holes punched through the stretching die, the inner diameter of the bowl-shaped semi-finished product increases sequentially from botto...

Abstract

The invention discloses a machining process of a loudspeaker basin stand with horizontal ear holes. The machining process comprises the steps of cutting, blanking, positioning hole punching, deepening, punching and trimming, ear pattern punching, single pattern punching, flanging and ear pressing and ear hole punching. By means of the machining process of the loudspeaker basin stand with the horizontal ear holes, the ear holes can be punched accurately.

Description

technical field [0001] The invention relates to the field of manufacturing audio equipment, in particular to a processing technology for a speaker basin frame with horizontal ear holes. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. [0003] The structure of the loudspeaker generally includes a bracket, a magnet, a pot frame, a fixed core support piece, a cone-shaped paper cone, etc. Among them, the pot frame is generally made of steel or aluminum...
