Description

Burr removing structure of fin longitudinal cutting die

Technical Field

The utility model relates to an air conditioner fin mould technical field especially relates to a fin rip cutting mould burring structure.

Background

An air conditioner fin, i.e., a heat sink for heat exchange in an air conditioner, is an important component of the air conditioner, which determines heat dissipation performance of the air conditioner. The fin die is a high-precision cold-punching progressive die for producing air conditioner fins.

In the production of the air conditioner fin, after the strip is punched and formed, the strip is cut into products with various widths in a die through longitudinal cutting, as shown in fig. 3, according to the product requirements and the completeness of the longitudinal cutting, a certain amount of over cutting exists, and the situation of local repeated cutting occurs.

SUMMERY OF THE UTILITY MODEL

Based on the problem, the utility model aims to provide a fin rip cutting mould burring structure through the position that changes rip cutting back fin, avoids the repetition position of cutting to improve the burr of eliminating even.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides a fin rip cutting mould burring structure, includes the rip cutting upper slitter and the rip cutting lower slitter of cooperation blank, its characterized in that, the rear of rip cutting lower slitter is provided with presses the flitch, presses the flitch violently cloth in the strip top, and presses and set up periodic recess on the flitch, and there is the difference in height in the both sides edge of recess, corresponds to act on the both sides limit of the strip after the rip cutting is cut apart to make the strip after the rip cutting be less than the knife face of rip cutting lower slitter and toward one side slope skew.

In particular, the recess comprises a cavity capable of accommodating the surface profile of the strip, one side of the cavity being raised and the other side being engaged with the projection of the other cavity.

In particular, the distance between adjacent projections is consistent with the width of the slit material strip.

In particular, the position of the projections coincides with the position of the slitting upper knife.

Specifically, the cross-sectional shape of the cavity is any one of a semicircular shape, a semi-elliptical shape, and a polygonal shape.

Particularly, the pressure plate is fixed on the template of the longitudinal cutting upper knife, and the lower edge of the pressure plate exceeds the knife surface of the longitudinal cutting upper knife.

To sum up, the beneficial effects of the utility model are that, fin rip cutting mould burring structure presses the flitch through the design after current rip cutting, carries out the strip material after the rip cutting by this pressure flitch and pushes down the skew to make it be less than the rip cutting plane, thereby avoid repeated cutting, effectively improve the burr condition even eliminated.

Detailed Description

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar parts throughout, or parts having the same or similar functions. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" are to be construed broadly and can include, for example, fixed or removable connections, mechanical or electrical connections, direct connections, indirect connections through an intermediary, communication between two elements, or an interaction between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.

In the description of the present invention, unless otherwise expressly specified or limited, the first feature "on" or "under" the second feature may include both the first and second features being in direct contact, and may also include the first and second features being in contact, not in direct contact, but with another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 and 2, the preferred embodiment provides a deburring structure for a fin longitudinal cutting die, which includes a longitudinal cutting upper knife 1 and a longitudinal cutting lower knife 2 matched with a cutting material, a pressure plate 3 is disposed behind the longitudinal cutting lower knife 2, the pressure plate 3 is transversely disposed above a strip 5, a periodic groove 4 is formed in the pressure plate 3, and a height difference exists between two side edges of the groove 4 and correspondingly acts on two side edges of the strip 5 after longitudinal cutting and division, so that the strip 5 after longitudinal cutting is lower than a knife surface of the longitudinal cutting lower knife 2 and is inclined and deviated to one side.

The recess 4 here comprises a cavity 41 capable of receiving the surface profile of the strip 5, the cavity 41 being bounded on one side by a projection 42 and on the other side by a projection 42 of the other cavity 41.

The distance between the adjacent bulges 42 is consistent with the width of the slit material strips, and the positions of the bulges 42 are consistent with the front and back of the slit upper knife 1, so that the single side of each strip material 5 is accurately pressed down, and the overturning deviation is realized.

The shape of the groove 4 is not limited, and can be designed according to the shape of a specific product, and the cross-sectional shape of the cavity 41 is preferably semicircular, semielliptical, polygonal and the like.

Further, the pressure plate 3 is fixed on the template of the longitudinal cutting upper knife 1, and the lower edge of the pressure plate 3 exceeds the knife surface of the longitudinal cutting upper knife 1, so that the longitudinal cutting is carried out while the longitudinal cut strip 5 is pressed downwards.

In summary, according to the fin longitudinal cutting die deburring structure, the material pressing plate is designed after the existing longitudinal cutting, the strip material subjected to longitudinal cutting is pressed downwards to be deviated by the material pressing plate and is lower than the longitudinal cutting plane, so that repeated cutting is avoided, and the burr condition is effectively improved or even eliminated.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention.
