Abstract
The utility model discloses a fin aggregation needle which comprises an aggregation needle body, wherein a material receiving part (1) and an aggregation stacking part (3) are arranged on the aggregation needle body in sequence from top to bottom; a transitional part (2) is arranged between the material receiving part (1) and the aggregation stacking part (3); the diameter of the tail end of the material receiving part (1) is greater than that of the head end of the transitional part (2), so that a function of preventing back suction is realized.
Description
Technical field
The utility model belongs to heat exchanger manufacturing technology field, relates in particular to a kind of fin pin that gathers materials.
Background technology
The fin that at present heat exchanger manufacturing the is used pin that gathers materials is comprised of the portion of connecting material and the accumulation portion that gathers materials, and the portion of connecting material is taper, and the accumulation portion that gathers materials is cylindricality, and the taper of the portion that connects material transits directly to the cylindricality of the accumulation portion that gathers materials.Taper connects material portion by the connect material dimension scale in portion and fin hole of expansion, make the connect material dimension difference in portion and fin hole of taper reach maximum, to produce the fin inaccurate problem that connects material that causes of rocking in the platform blanking process that prevents from gathering materials, but in normal productive process, tradition gather materials pin because of the taper portion's transition that connects material longer, intensity is little, easily causes the bending situation that fractures; The pin landing Transition Design that gathers materials is tapering transition, and the taper portion's diameter that connects material becomes greatly gradually, and the accumulation portion diameter that gathers materials is maximum, and fin is piled up in the accumulation portion that gathers materials, when feed height is too high or blanking landing is crossed and easily caused fin suck-back phenomenon when slow.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of fin that prevents fin suck-back pin that gathers materials.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of fin pin that gathers materials, comprise the pin body that gathers materials, the described pin body that gathers materials is provided with the portion of connecting material and the accumulation portion that gathers materials from top to bottom successively, the described portion and gather materials and be provided with transition part between accumulation portion of connecting material, described in the portion's tail end diameter that connects material be greater than transition part head end diameter.
Described transition part is cylindrical.
Described transition part diameter is 6mm.
The described portion of connecting material is bullet-headed.
The described portion's tail end that connects material is connected by rounding transition with transition part head end.
The described portion's tip diameter that connects material is 1.4mm, and tail end diameter is 8mm, and length is 12mm.
The described accumulation portion that gathers materials is followed successively by tapered portion and cylindrical portion from top to bottom.
The utility model has the advantage of, connect material portion and transition part form two-stage transition, and the portion's tail end diameter that connects material is greater than transition part head end diameter, realizes the function of anti-suck; The landing effect of fin has been strengthened in two-stage transition, and transition part adopts the cylindrical Transition Design of diameter 6mm, to reach the best landing effect of fin; Bullet-headed needle point has shortened the transition length at the position that connects material under the prerequisite that does not affect the function that connects material, and has increased needle point position intensity.
Accompanying drawing explanation
Fig. 1 is the gather materials structural representation of pin of a kind of fin of the utility model;
Mark in above-mentioned figure is: the portion that 1, connects material, 2, transition part, 3, accumulation portion gathers materials.
The specific embodiment
Fig. 1 is the gather materials structural representation of pin of a kind of fin of the utility model, comprises the pin body that gathers materials, and the pin body that gathers materials is provided with the portion of connecting material 1, transition part 2 and the accumulation portion 3 that gathers materials from top to bottom successively, and the portion 1 that connects material is for bullet-headed; Portion's 1 integral body that connects material is tapered, and tail end diameter is greater than tip diameter, and side is cambered surface, and bus is that radius is the circular arc of 70mm.Bullet-headed needle point transition has shortened the transition length at the position that connects material under the prerequisite that does not affect the function that connects material, and has increased the intensity at needle point position.
The portion's 1 tail end diameter that connects material is greater than transition part 2 head end diameters, adopts such diameter transition to connect, and in the situation that not affecting fin landing, realizes the function of anti-suck.
Transition part 2 is cylindrical.Transition part 2 diameters are 6mm.The best landing diameter of landing intermediate location of pin of gathering materials is 6mm, therefore transition part 2 is designed to the cylinder that diameter is 6mm, has strengthened the landing effect of fin, and landing is smooth and easy.
Portion's 1 tail end that connects material is connected by rounding transition with transition part 2 head ends, and transition connects smooth-going, realizes the function of anti-suck.
Portion's 1 tip diameter that connects material is 1.4mm, and tail end diameter is 8mm, and length is 12mm.The needle point of this size has shortened the transition length at the position that connects material under the prerequisite that does not affect the function that connects material, and has increased the intensity at needle point position.
The accumulation portion 3 that gathers materials is followed successively by tapered portion and cylindrical portion from top to bottom.
Adopt after above-mentioned structure, adopt a minute function, stagewise to be connected transition, prevent fin suck-back; Transition part 2 adopts the cylindrical Transition Design of diameter 6mm, to reach the best landing effect of fin; Bullet-headed needle point has shortened the transition length at the position that connects material under the prerequisite that does not affect the function that connects material, and has increased needle point position intensity.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
