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 multi-level steps in the pot frame, and the sides of the steps are divided into inclined surfaces and vertical surfaces. Stamping has higher difficulty

Embodiment 1

[0023] Such as figure 1 and figure 2 Shown, a kind of processing technology of the loudspeaker pot frame that stretches for many times, comprises the following steps:

[0024] Step 1: cutting, cut out a strip of coil material that is 209 millimeters wide on the cold-rolled carbon steel sheet that thickness is 0.6 millimeters by shearing machine;

[0025] Step 2: Blanking, punching out a square raw material with a side length of 209 mm on the coiled material through a blanking continuous die;

[0026] Step 3: punching grooves, punching a groove 1 on the square raw material through a punching groove continuous die, the inner diameter of the groove 1 is 94.26 mm, and the outer diameter of the groove 1 is 107 mm, The center of the groove 1 coincides with the center of the square material;

[0027] Step 4: Stretching for the first time, punching out the first step 2 from the square raw material punched with the groove 1 through the continuous die for the first stretching, the h...

Abstract

The invention discloses a processing technique for a repeatedly stretched speaker frame. The processing technique for the repeatedly stretched speaker frame includes steps of cutting, blanking, notching, primary stretching, secondary stretching, pattern punching, ear hole pressing, punching, trimming and flanging. The processing technique for the repeatedly stretched speaker frame is capable of precisely punching each step.

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 that has been stretched multiple times. 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 ...
