CN201324797Y - Inside and outside chip flanging die of oil cooler - Google Patents

Abstract

An inside and outside chip flanging die of oil cooler comprises a convex die (1) and a concave die (2), wherein two end edges of the convex die (1) are in arc shapes, the edges of a die cavity of the concave die (2) which is matched with the convex die (1) is in the arc shape which is matched with the convex die edges, after the structure is adopted, compared with the prior art, the inside and outside chip flanging die of oil cooler has the following advantages that the inside and outside chip flanging die of oil cooler after improvement can punch arc-shaped edges of inside and outside chips of the oil cooler in the punching and shaping process, and can effectively avoid edge burrs on the basis of guaranteeing the original cooling effect, since the edges do not have straight sides and corners, the cracking phenomena can be completely avoided, and the product pass percent can be improved.

Description

The inside and outside chip flange die of oil cooler

Technical field

The utility model relates to a kind of mould of punch process, specifically is the inside and outside chip flange die of a kind of oil cooler.

Background technology

The punch upward view and the matrix cavity vertical view of the inside and outside chip flange die of existing oil cooler all are rectangular, the inside and outside chip of the oil cooler that punching press is come out sees it is rectangular from vertical view, both ends are straight flanges, in punching course, burr appears in straight portion easily, even fracture, cause product percent of pass very low.

The utility model content

Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of inside and outside chip straight flange of oil cooler that can effectively avoid producing burr and phenomenon of rupture to occur, improves the inside and outside chip flange die of oil cooler of product percent of pass.

For solving the problems of the technologies described above, the inside and outside chip flange die of the oil cooler that the utility model provides, comprise punch and die, the edges at two ends of described punch is an arc, the arc of the edge of the die cavity that described die matches with punch for matching with the punch edge.

After adopting above structure, the inside and outside chip flange die of the utility model oil cooler compared with prior art has the following advantages:

The inside and outside chip flange die of oil cooler after the improvement, in stamping forming process, the inside and outside chip edge of the oil cooler that punching press is come out is an arc, on the basis that guarantees original cooling effect, can effectively avoid burrs on edges, owing to do not had straight flange and angle, thoroughly avoided phenomenon of rupture, improved the qualification rate of product.

Description of drawings

Fig. 1 is that the punch of the inside and outside chip flange die of the utility model oil cooler is looked up structural representation.

Fig. 2 is the die plan structure schematic diagram of the inside and outside chip flange die of the utility model oil cooler.

Wherein, 1, punch; 2, die.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As depicted in figs. 1 and 2, the inside and outside chip flange die of the utility model oil cooler comprises punch 1 and die 2, and the edges at two ends of described punch 1 is an arc, the arc of the edge of the die cavity that described die 2 matches with punch 1 for matching with punch 1 edge.

Claims (1)

1, the inside and outside chip flange die of a kind of oil cooler, comprise punch (1) and die (2), it is characterized in that: the edges at two ends of described punch (1) is an arc, the arc of the edge of the die cavity that described die (2) matches with punch (1) for matching with punch (1) edge.
