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 that are not strictly symmetrical, traditional craftsmanship cannot be achieved

Embodiment 1

[0022] like figure 1 and figure 2 As shown in the figure, a processing technology of the loudspeaker pot frame with punching the ear flower first and then punching the center hole includes the following steps:

[0023] Step 1: cutting, cutting out a strip with a thickness of 0.8 mm and a width of 196 mm by a slitting machine;

[0024] Step 2: Blanking, punching out a circular blank with a diameter of 192 mm on the coil material through the blanking die; the diameter of the punching needle of the blanking die is 192 mm;

[0025] 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;

[0026] Step 4: deep drawing, a bowl-shaped semi-finished product is punched out on the circular blank with positioning holes punched through the deep-drawing die, and the inner diameter of the bowl-shaped semi-finished product increases sequentially from bottom to top, so The bowl-...

Abstract

The invention discloses a speaker frame machining process performed by sequentially punching ear flowers and a center hole. The speaker frame machining process performed by sequentially punching the ear flowers and the center hole includes a series of steps of rough shape cutting, blanking, location hole punching, deep drawing, hole punching and edge trimming, ear flower punching, flanging and hole punching. The speaker frame machining process performed by sequentially punching the ear flowers and the center hole is suitable for accurately punching the ear flowers and the ear hole.

Description

technical field [0001] The invention relates to the field of manufacturing audio equipment, in particular to a processing technology for a loudspeaker pot frame in which the ears are punched first and then the center hole is punched. 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 ...
