Abstract

The invention relates to a one-time deep-drawing forming device for a magnetic conductive bowl of a loudspeaker. The one-time deep-drawing forming device is characterized in that a connecting piece connected with a machine tool is mounted on the upper surface of an upper die sleeve, and an upper die groove is formed in the lower bottom surface of the upper die sleeve; a lower die is arranged below the upper die sleeve; a bulge structure corresponding to the upper die groove is formed on the upper surface of the lower die, and the groove and the bulge structure are matched with a to-be-processed shape of a product; the bottom surface of the lower die is mounted on a bottom plate, the lower part of the bottom plate is connected with a base, and multiple rubber pads are arranged between the bottom plate and the base; a lifting plate is coaxially mounted on the outer side of the upper end of the lower die in a sleeving manner, the bottom surface of the lifting plate is connected with a press plate, and the press plate is located between the bottom plate and the rubber pad at the uppermost end. The one-time deep-drawing forming device for the magnetic conductive bowl of the loudspeaker is reasonable in design, simple in structure, easy to manufacture, convenient to use and high in practicability, the device is a special tool with targeted performance, and the product quality and the working efficiency can be greatly improved with the adoption of the device.

Description

A kind of magnetically conducting bowl for loudspeaker once draws deep shaped device
Technical field
The present invention relates to speaker machining technique field, especially a kind of magnetically conducting bowl for loudspeaker once draws deep shaped device.
Background technology
Auto loud hailer magnetic conductor bowl is owing to wall thickness is relatively thin and stretching depth is relatively big, and when therefore now magnetic conductor bowl being carried out drawing and forming, stretch process generally falls into twice, can be only achieved prescription.It is easily broken off according to one-shot forming then workpiece, causes that percent defective rises, affect the economic benefit of enterprise.
Summary of the invention
It is an object of the invention to make up the deficiencies in the prior art part, it is provided that a kind of magnetically conducting bowl for loudspeaker that can improve working (machining) efficiency products quality guarantee once draws deep shaped device.
It is an object of the invention to be realized by techniques below means:
A kind of magnetically conducting bowl for loudspeaker once draws deep shaped device, it is characterised in that: including Upper Die-sleeve cylinder, counterdie, lifter plate, base plate and base, the upper surface of Upper Die-sleeve cylinder installs the connector being connected with lathe, and the bottom surface of Upper Die-sleeve cylinder makes mould groove;Counterdie is arranged on the lower section of Upper Die-sleeve cylinder, and the upper surface of counterdie is made the bulge-structure corresponding with upper mould groove, this groove and bulge-structure and matched with product shape to be processed;The bottom surface of counterdie is arranged on a base plate, and this base plate bottom connects a base, puts multiple rubber blanket between base plate and base;One lifter plate of the outside coaxial package of counterdie upper end, the bottom surface of this lifter plate connects a pressing plate, and this pressing plate is at base plate with topmost between rubber blanket.
And, described lifter plate connects pressing plate by multiple bolts, this bolt traverse base plate.
Advantages of the present invention and having the benefit effect that
1, originally drawing deep shaped device and include upper die and lower die, its binding face is processed into the shape meeting product, therefore makes this device become pointed special device, adds man-hour, chooses the device of corresponding model, product can once draw plutonic type.Through overtesting, use this device the steel plate of 0.5 can once be drawn deep 40mm, and nothing is pulled, nothing fracture, belongs to leading technology in the same industry.
2, originally draw the rubber blanket that deep shaped device uses and can improve the effect of stretching further.
3, employing can improve work efficiency, raising automatization level, products quality guarantee, rate of reducing the number of rejects and seconds, the profit increasing enterprise and the market competitiveness after originally drawing deep shaped device.
4, the present invention is that a kind of reasonable in design, simple in construction, easily fabricated, easy to use, practical magnetically conducting bowl for loudspeaker once draw deep shaped device, this set composite is pointed specific purpose tool, and product quality and work efficiency can be greatly improved after adopting this device.
Accompanying drawing explanation
Fig. 1 is the front view (broken section) of the present invention.
Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing;It should be noted that the present embodiment is narrative, it not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of magnetically conducting bowl for loudspeaker once draws deep shaped device, including Upper Die-sleeve cylinder 2, counterdie 4, lifter plate 5, base plate 7 and base 10.The upper surface of Upper Die-sleeve cylinder installs the connector 1 being connected with lathe, and the bottom surface of Upper Die-sleeve cylinder makes mould groove 3.Counterdie is arranged on the lower section of Upper Die-sleeve cylinder, and the upper surface of counterdie is made the bulge-structure corresponding with upper mould groove, this groove and bulge-structure and matched with product shape to be processed.
The bottom surface of counterdie is arranged on a base plate, and this base plate bottom connects a base, installs multiple rubber blanket 9 between base plate and base.One lifter plate of the outside coaxial package of counterdie upper end, the multiple bolt 6 of underrun of this lifter plate connects a pressing plate 8, bolt traverse base plate.This pressing plate is at base plate with topmost between rubber blanket.
The operation principle of the present invention is:
Being placed workpiece to be processed on counterdie and lifter plate, lathe drives Upper Die-sleeve cylinder to move downward, and Upper Die-sleeve cylinder makes lifter plate decline, and carries out punching press with counterdie, and what can complete to lead china bowl draws plutonic type.
