A stable loudspeaker cone punching forming mechanism

Abstract

The application discloses a stable loudspeaker cone stamping forming mechanism, which comprises a supporting base, a side support, a top horizontal plate, an upper module, a lower die base, a control mechanism and a floating adsorption assembly. The cone is installed at the upper end of the lower die base. The adsorption block adsorbs the cone through the driving of the air pump. Then, the upper module presses the cone downward, so that the cone, the adsorption block and the floating pipeline move downward. The cone is shaped by the forming groove of the lower die base. The adsorption block enters the pressing groove. The pressing protrusion is inserted into the pressing groove. Thus, the closed stamping shaping of the upper module and the lower die base is formed. When the cone moves downward, the adsorption of the adsorption block and the clamping positioning of the adsorption block and the pressing protrusion prevent the position of the cone from moving during the downward shaping, so that the stable stamping structure is formed.

Description

Technical Field

[0001] This invention relates to a stable loudspeaker cone stamping mechanism. Background Technology

[0002] In a loudspeaker, the voice coil vibrates strongly in a magnetic field after an audio signal is applied. The voice coil is fixed to the cone, and its vibration simultaneously drives the cone to vibrate. This cone vibration forces the air to vibrate, thus producing sound. To achieve good sound quality, the cone is typically made in a conical shape. However, with continuous technological advancements and increasing demands for sound quality, cones made of various materials have emerged, no longer limited to paper. Examples include wool and metal cones. Currently, the cone is generally formed by stamping. This is done by placing the cone on top of a lower module and then pressing it down to close the lower module. However, when the upper module presses downwards, the cone may shift position on top of the lower module, causing the stamping position to deviate and deforming the entire cone, thus failing to meet requirements. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a stable speaker cone stamping mechanism with a stable cone position.

A support base is installed on each of the lower two sides of the lower die base. A side bracket is installed on the upper sides of the lower die base, and the upper ends of the side brackets are connected to a top horizontal plate. The upper module is installed directly above the lower die base. The control mechanism is installed on the side brackets and the top horizontal plate, and drives the upper module to move up and down. The upper end of the lower die base has a forming groove, a pressing groove is provided in the lower middle of the forming groove, and a through-hole is provided below the pressing groove. The lower end face of the upper module has a downward convex structure. A pressing protrusion is provided in the middle of the lower end of the upper module. The floating adsorption assembly is installed on the lower die base. The floating adsorption assembly includes an adsorption block, a floating pipe, a sleeved elastomer, a telescopic pipe, a bottom positioning pipe, and an air pump. The floating pipe floats vertically and passes through a pressure groove and a through-channel. A sleeved elastomer is installed inside the through-channel. The sleeved elastomer is sleeved around the outside of the floating pipe, and its upper end elastically presses against the floating pipe to move upward. The upper end of the floating pipe extends above the pressure groove. The upper end of the floating pipe is connected to the adsorption block. The upper end of the adsorption block is evenly provided with multiple adsorption holes. The lower end of the floating pipe extends below the lower mold base. The lower end of the floating pipe is connected to the telescopic pipe. The lower end of the telescopic pipe is connected to the bottom positioning pipe. The bottom positioning pipe is fixedly connected to a support base. An air pump is installed at the outer end of the bottom positioning pipe.

[0006] Furthermore, the telescopic pipe is made of corrugated pipe material.

[0007] Furthermore, the control mechanism includes a side positioning rod, a side slider, a floating sleeve, a threaded column, a control motor, and a drive shaft; a side positioning rod is installed on each side of the upper module, and a side slider is installed on the outer end of each side positioning rod, with the side slider slidably engaged with the inner side of the side bracket; a floating sleeve is installed on one of the side positioning rods; a control motor is installed on the top horizontal plate, with the lower end of the control motor connected to the drive shaft, and the lower end of the drive shaft connected to the threaded column, which is threaded through the floating sleeve, with the lower end of the threaded column rotatably engaged with one side of the lower mold base.

[0008] Furthermore, a positioning block is provided on one side of the lower mold base; the lower end of the threaded column is rotatably engaged with the upper end face of the positioning block.

[0009] Furthermore, the bottom of the forming groove has a downwardly concave arc surface structure; the forming groove and the lower end face structure of the upper module are matched; the pressing protrusion and the pressing groove are matched.

[0010] Furthermore, the upper end of the forming groove is provided with an abutting ring surface; the abutting ring surface is provided with a limiting ring body.

[0011] Furthermore, the upper surface of the adsorption block and the contact ring surface are on the same horizontal plane.

[0012] The beneficial effects of this invention are as follows: This invention installs a paper basin on the upper end of the lower mold base. Driven by an air pump, the adsorption block adsorbs the paper basin. Then, the upper module presses the paper basin downward, causing the paper basin, adsorption block, and floating pipe to move downward. The paper basin is shaped to fit the forming groove of the lower mold base. The adsorption block enters the pressing groove, and the pressing protrusion is inserted into the pressing groove. This forms a closed stamping and shaping of the entire upper module and lower mold base. When the paper basin moves downward, the adsorption of the adsorption block and the clamping and positioning of the adsorption block and the pressing protrusion ensure that the position of the paper basin does not move during downward forming, forming a stable stamping structure.

The upper end of the floating pipe 71 extends above the pressure groove 52. The upper end of the floating pipe 71 is connected to the adsorption block 72. The upper end of the adsorption block 72 is evenly provided with multiple adsorption holes. The lower end of the floating pipe 71 extends below the lower mold base 5. The lower end of the floating pipe 71 is connected to the telescopic pipe 74. The lower end of the telescopic pipe 74 is connected to the bottom positioning pipe 75. The bottom positioning pipe 75 is fixedly connected to a support base 1. The outer end of the bottom positioning pipe 75 is equipped with an air pump 76.

[0020] like Figures 1 to 5 As shown, in order to ensure that the adsorption block 72 can also automatically reset upward after the upper module 4 moves upward and resets, preferably, an upper limit ring 57 is provided between the through-channel 53 and the pressing groove 52, and a lower limit ring 56 is provided at the lower end of the through-channel 53; an abutment ring 711 is provided on the outer periphery of the floating pipe 71; the abutment ring 711 is slidably engaged with the through-channel 53; the upper and lower ends of the sleeve elastic body 73 elastically press against the abutment ring 711 and the lower limit ring 56 respectively; the upper end of the sleeve elastic body 73 elastically presses against the abutment ring 711 and drives the abutment ring 711 to abut against the lower side of the upper limit ring 57.
