Abstract
The invention relates to a fine blanking compound device for a lower plate of a loudspeaker. The fine blanking compound device is characterized in that a lower die is mounted on the upper surface of a bottom plate, the bottom of the lower die is connected with a support plate located below the bottom plate, a press ring is coaxially mounted on the outer side of the upper part of the lower die in a sleeving manner, and the bottom of the press ring is connected with a transition plate; two guide pillars are symmetrically arranged on the left side and the right side of the lower die and are coaxially sleeved with springs, and the guide pillars at the upper ends of the corresponding springs are sleeved with guide sleeves; the left side and the right side of the press plate are inserted into the two guide sleeves, an upper die corresponding to the lower die is mounted on the lower bottom surface of the press plate, and an annular concave chamfer and an annular convex chamfer which are matched with the shape of a product are formed in the attached surfaces of the upper die and the lower die respectively. The fine blanking compound device for the lower plate 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 with the adoption of the device, the product quality can be greatly improved and the processing speed can be greatly increased; manpower is saved, and profits are increased.
Description
Technical field
The present invention relates to speaker machining technique field, especially a kind of speaker lower plate fine set composite.
Background technology
The middle part of auto loud hailer lower plate needs to process an interstitial hole, and product is different, and hole depth is just different.Generally, raw material is more thick, and interstitial hole needs the more deep of processing, and difficulty of processing is more big, is more difficult to ensure machining accuracy.It is generally artificial during current punching processing, therefore problems with easily occurs: 1, the very difficult guarantee such as the precision of interstitial hole, fineness, cause that product percent defective rises, affect the economic benefit of enterprise；2, not only add the labor intensity of staff, and along with the increase of difficulty, the technical merit of staff is required more high；3, automaticity is low, and human cost is high.
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 speaker lower plate fine set composite that can improve working (machining) efficiency products quality guarantee.
It is an object of the invention to be realized by techniques below means:
A kind of speaker lower plate fine set composite, including pressing plate, base plate, upper die and lower die, pressure ring and guide pillar, the upper surface of base plate installs counterdie and two vertical guide pillars, the bottom of this counterdie connects a gripper shoe being positioned at below base plate, one pressure ring of the outside coaxial package on counterdie top, the bottom of this pressure ring connects a rebound, and this rebound is between base plate and gripper shoe, and puts multiple rubber blanket between rebound and gripper shoe；Two guide pillars are symmetricly set on the left and right sides of counterdie, equal coaxial package spring on two guide pillars, are set with guide pin bushing on the guide pillar of spring upper end；Plug-in opening is all made in the left and right sides of pressing plate, and this plug-in opening is coaxially inserted on two guide pin bushings in left and right, and the bottom surface of pressing plate installs a upper mould corresponding with counterdie, and the binding face of these upper die and lower die makes the annular concave-convex groove matched with shape of product respectively.
And, multiple through hole is made on the surface of described guide pin bushing, is all embedded in ball in it.
Advantages of the present invention and having the benefit effect that
1, this set composite is respectively mounted upper die and lower die on pressing plate and base plate, and makes, at the binding face of upper die and lower die, the annular concave-convex groove matched with shape of product respectively, therefore can process required product by the punching press laminating of upper die and lower die.Due to the special device that this device is pointed, therefore can according to the difference of the punching degree of depth, make the device of multiple different size, add man-hour, choose corresponding model number devices, the precision of processing and the fineness of interstitial hole can be ensured, it is ensured that tangent plane is smooth without fracture belt, improves conforming product rate and improves the economic benefit of enterprise.
2, this set composite can be connected with lathe and is processed, it is achieved that automated production, accelerate speed of production, improve work efficiency.
3, the labor intensity that can reduce a staff after adopting this device, the quantity reduced a staff, thus reducing human cost.
4, the present invention is a kind of reasonable in design, simple in construction, easily fabricated, easy to use, practical speaker lower plate fine set composite, this set composite is pointed specific purpose tool, product quality and process velocity can be improved after adopting this device, save manpower, increase profit.
Accompanying drawing explanation
Fig. 1 is the front view (local is partly cutd open) of the present invention；
Fig. 2 is the top view of counterdie.
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 speaker lower plate fine set composite, including pressing plate 1, base plate 12, upper mould 2, counterdie 10, pressure ring 9 and guide pillar 11.The upper surface of base plate installs counterdie and two vertical guide pillars, the bottom of this counterdie connects a gripper shoe being positioned at below base plate 13, one pressure ring of the upper outside coaxial package of counterdie, the bottom of this pressure ring connects a rebound 14, this rebound is between base plate and gripper shoe, and puts multiple rubber blanket 15 between rebound and gripper shoe.This rubber blanket can play cushioning effect, is avoided that device is impaired and ensures product processing quality.
Two guide pillars are symmetricly set on the left and right sides of counterdie, equal coaxial package spring 7 on two guide pillars, are set with guide pin bushing 5 on the guide pillar of spring upper end.Multiple through hole is made on the surface of guide pin bushing, is all embedded in ball 6 in it.This design can improve guide effect, it is ensured that pressing plate operates steadily.Plug-in opening is all made in the left and right sides of pressing plate, this plug-in opening is coaxially inserted on two guide pin bushings in left and right, the bottom surface of pressing plate installs a upper mould corresponding with counterdie, the binding face of these upper die and lower die makes the annular concave-convex groove 4 and 8 matched with shape of product respectively, and joins for gapless zero between tongue and groove.The upper surface of pressing plate installs a branch sleeve 3 for being connected with lathe.
The operation principle of the present invention is:
First being placed on counterdie by workpiece to be processed, then utilize lathe to make pressing plate drive upper mould to move downward, pressure ring moves downward, and can be gone out by workpiece center hole.
