Description

Bending device of computer adapter fin

Technical Field

The utility model belongs to the technical field of computer adapter fin processing equipment, especially, relate to a bending device of computer adapter fin.

Background

The computer adapter fin is applied to the adapter, plays the heat dissipation function, need punch the processing to the fin usually, among the prior art, owing to appear more processing waste residue after punching, can't guarantee on the precision machining, if there is the demand of chamfer processing, the precision of chamfer can be influenced to the waste residue, can't process out stable product, especially on the adapter of miniaturization, lead to the unable installation in later stage, cause the waste of material.

SUMMERY OF THE UTILITY MODEL

An object of the embodiment of the utility model is to provide a bending device of computer adapter fin can make the processing tiny particle waste residue that punches reduce, and accurate location reduces the material and warp, guarantees the machining precision of product.

The embodiment of the utility model provides a realize like this:

a bending device for a computer adapter cooling fin comprises: the upper die base is fixedly connected with the clamping plate, the upper die base is connected with the lower die base through the outer guide pillars, the inner guide pillars are connected between the lower die plate and the upper die base, the lower die plate is fixed on the lower die base, the floating pins are arranged on the lower die plate, the lower dies are respectively embedded in the lower die plate, the upper dies and the lower dies are consistent in number, the upper ends of the upper dies are embedded in the clamping plate, the lower ends of the upper dies are arranged in the stripper plate in a penetrating mode, a plurality of corresponding outlets of the upper dies are arranged below the stripper plate and respectively located right above the lower dies, the stripper plate and the clamping plate are arranged at intervals vertically, the upper sides of the stripper plate and the clamping plate are sleeved on the inner guide pillars at the same side, the other sides of the stripper plate and the clamping plate are connected through pillars in a sliding mode, and the guide pins are fixed in the stripper plate and extend out of the lower end face of the stripper plate.

The embodiment of the utility model provides a through be equipped with the guide pin of beating the blind hole on bending device, beat the blind hole operation to the position of beating, realize locate function, also accomplished the first step operation that punches, reduce the material and warp, bend the processing to the sheet stock simultaneously, then carry out chamfer processing again, reduce the processing waste residue, beat the through-hole secondary operation of punching after the chamfer has been accomplished again, like this under the condition that does not influence the precision, can reduce the processing waste residue, guarantee processingquality.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The following detailed description is given to specific implementations of the present invention with reference to specific embodiments:

as shown in fig. 1, a bending device for a heat sink of a computer adapter includes: the upper die base 1, outer guide pillar 2, lower die base 3, inner guide pillar 4, splint 5, go up mould 6, bed die 7, lower bolster 8, guide pin 9, buoyancy lift pin 10 and stripper plate 11, the upper die base is connected with splint fixed connection, the upper die base passes through outer guide pillar with the bed die and is connected between lower bolster and upper die base, the lower bolster is fixed on the bed die, be equipped with the buoyancy lift pin on the lower bolster, the bed die is a plurality of, arrange respectively and inlay the dress in the lower bolster, the number of upper die is unanimous with the bed die, the upper end of upper die inlays the dress in splint, the lower extreme wears to establish in stripper plate, the below of stripper plate is equipped with a plurality of corresponding exports of upper die, a plurality of corresponding exports respectively are located directly over the bed die, stripper plate and splint interval set up and down, all cup joint on inner guide pillar in the same side, the opposite side of stripper plate and splint passes through post sliding connection, the guide pin is fixed in stripper plate and extends the lower terminal surface of stripper plate.

When processing, fix the material on the buoyancy lift pin, the upper die base is along outer guide pillar downstream, drive splint along inner guide pillar downstream, and then drive and take off the flitch and also along inner guide pillar downstream, when taking off the sheet stock on flitch touching buoyancy lift pin, continue downstream and stop until touching the lower bolster, the blind hole is beaten into with the material in the department of punching to the guide pin this moment, the first step of punching has been accomplished, and realize fixed function, because take off flitch and splint interval slip setting, splint drive the mould and continue downstream, until last mould extrudees the sheet stock to the bed die on, the sheet stock will form the shape after mould and the bed die extrusion like this, the process of bending has been accomplished.

After the processing, take out the material, carry out the chamfer processing to the blind hole on chamfering equipment, later carry out the secondary operation of punching to the blind hole again, form the through-hole, guaranteed the machining precision. Because the punching is completed in two times, the required impact force is smaller when the punching is performed for the second time, so that the small particles forming the waste residues are less, the material deformation is smaller, and the processing quality is not influenced.

The embodiment of the utility model provides a through be equipped with the guide pin of punching the blind hole on bending device, punch the blind hole operation to the punching position, realize the locate function simultaneously, bend the processing to the sheet stock simultaneously, then carry out chamfer processing again, reduce the processing waste residue, punch the through-hole operation again after the chamfer has been accomplished, like this under the condition that does not influence the precision, can reduce the granule waste residue of processing, guarantee processingquality.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
