Abstract
The utility model relates to a compound dust-proof sheet punch die of a roller wheel, which comprises an upper punch and a lower punch, and is characterized in that the upper punch is provided with a round outer knife edge and an H-shaped inner knife edge; an upper blanking die is arranged between the inner knife edge and the outer knife edge; the upper blanking die is connected with a spring; the lower punch is provided with an inner knife edge and an outer knife edge corresponding to those of the upper punch; and the center of the upper punch is provided with a lower blanking die which can subside. The compound dust-proof sheet die has the advantages that when in pressing, plates are put on the lower punch, the upper punch moves downwards for punching the plates, and under the action of the inner knife edges and the outer knife edges, the plates are cut into round dust-proof sheets with H-shaped holes. After pressing, under the action of the spring, the squeezed upper blanking die pushes the dust-proof sheets pasted on the dust-proof sheets on the upper punch down, thus completing demolding. The compound dust-proof sheet die with the structure is used for producing the dust-proof sheets, thus leading to high pressing efficiency and convenient demolding, and greatly improving the production efficiency.
Description
Technical field
The utility model relates to a kind of punch die, particularly a kind of production efficiency height, the compound roller dustproof sheet punch die that is convenient in demoulding.
Background technology
The dustproof sheet of compound roller can prevent that extraneous impurity such as dust from entering in the bearing, reduces the service life of bearing.Traditional dustproof sheet preparation method is: material is placed under the template with the dustproof sheet profiling, makes by manually beaing, and dustproof sheet easily is bonded on the template, difficult drop-off need manually take off, and production efficiency is low.
The utility model content
The punch die of the compound roller dustproof sheet that the technical problems to be solved in the utility model provides a kind of production efficiency height, be convenient in demoulding.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of compound roller dustproof sheet punch die, comprise upper punch and bottom punch, it is characterized in that: described upper punch is provided with edge of a knife B in circular outer edge of a knife A and the I shape, in described, outer edge of a knife A, be provided with loading and unloading mould C between the B a little more than the upper punch end face, the end of described loading and unloading mould is equipped with spring, described bottom punch be provided with upper punch in, outer edge of a knife B, edge of a knife B ' and outer edge of a knife A ' in A is corresponding, described bottom punch center is provided with down blanking die C ', described blanking die C ' down is connected with buffer board by guide pillar, and the below of described buffer board is provided with yielding rubber.
Advantage of the present utility model is: during compacting, bottom punch is fixed on the workbench of hydraulic press, upper punch is connected with hydraulic jack, the sheet material of compacting usefulness is placed on the bottom punch, the descending pressing sheet material of upper punch becomes the center to have the circular dustproof sheet in I shape hole sheet shearing under the effect of the inside and outside edge of a knife.After compacting was finished, the dustproof sheet on the edge of a knife pushed the loading and unloading mould that is extruded inside and outside the upper punch will being bonded under the effect of spring, finishes the demoulding.Adopt the compound roller dustproof sheet punch die of this structure to produce dustproof sheet, compacting efficient height is convenient in demoulding, and has improved production efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of the compound roller dustproof sheet of the utility model punch die.
Fig. 2 is a upper punch upward view of the present utility model.
Fig. 3 is a bottom punch vertical view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model relates to a kind of roller dustproof sheet punch die that meets, it comprises upper punch 1 and bottom punch 2, the lower surface of described upper punch 1 is provided with a circular outer edge of a knife A, the center is provided with edge of a knife B in the I shape, dig the cavity of forming by by the profile of outer edge of a knife A and interior edge of a knife B between described outer edge of a knife A and the interior edge of a knife B, be provided with the loading and unloading mould C a little more than upper punch end face 1 in the described cavity, its end is equipped with spring.Be provided with outer edge of a knife A ' corresponding and interior edge of a knife B ' with the outer edge of a knife A of upper punch 1, interior edge of a knife B in the upper surface of bottom punch 2.
Be provided with blanking die C ' down at the center of bottom punch 2, its guide pillar 3 by two ends is connected with buffer board 4, is filled with yielding rubber below buffer board 4.When upper punch 1 presses down, following blanking die C ' moves down under the pressure of upper punch 1 slightly, make bottom punch 2 stretch in the upper punch 1, interior edge of a knife B, outer edge of a knife A and interior edge of a knife B ' and outer edge of a knife A ' cross-shear become the center to have the circular dustproof sheet in I shape hole plate stamping.Upper punch 1 is when stretching into bottom punch 2, its loading and unloading mould C and spring thereof are compressed by bottom punch 2, after compacting is finished, when upper punch 1 retreats, loading and unloading mould C pushes the dustproof sheet that is bonded on the upper punch 1 inside and outside edge of a knife under the effect of spring, realizes the demoulding, punching press, the demoulding are once finished, the production efficiency height.
