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, especially when there are too many through-hole blanks in the pot frame, how to accurately control the size of the blanks and set the positioning of the blanks is an urgent task. issues that need resolving

Embodiment 1

[0019] like figure 1 and figure 2 Shown, a kind of processing technology of the loudspeaker basin frame with multiple blanks, comprises the following steps:

[0020] Step 1: cut the material, cut out a width of 104 mm on a cold-rolled carbon steel sheet with a thickness of 0.5 mm by a shearing machine, and be long 1250 mm of coil material;

[0021] Step 2: blanking stretching, punching out a circular raw material with a diameter of 103 mm on the coiled material through the blanking stretching die; and stretching the circular raw material into a bowl-shaped semi-finished product. The inner diameter of the bowl-shaped semi-finished product increases successively from bottom to top, and the described bowl-shaped semi-finished product is composed of three steps from bottom to top, and the three steps include a first step with a height of 4.5 mm. The second step 2 with a height of 17.5 mm and the third step 3 with a height of 3 mm;

[0022] Step 3: punching and trimming, punchi...

Abstract

The invention discloses a processing technique for a speaker frame with a plurality of blanks. The processing technique for the speaker frame with a plurality of blanks includes steps of cutting, blanking, stretching, punching, trimming, single pattern punching, ear hole punching and air hole punching. The processing technique for the speaker frame with a plurality of blanks is capable of precisely punching each blank.

Description

technical field [0001] The invention relates to the field of manufacturing audio equipment, in particular to a processing technology for a loudspeaker basin frame with multiple blanks. 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,...
