Abstract

The utility model discloses an anti-crinkling structure for a sheet punching and drawing die, aiming at avoiding local crinkling and distortion due to uneven drawing force in the punching die of the heat exchanger fin of an air conditioner. The anti-crinkling structure is structurally characterized in that the punching and drawing die is arranged in two rows of holes at the edges of the sheet; an equilibrium position(3)is arranged on the orderly arranged imperforate row at the initial position, and is symmetrical with the holes at the initial position of the other row; a pair of drawing and balancing punch-dies, contacting with the sheet, are arranged on the equilibrium position(3). Adopting above technical proposal, the anti-crinkling structure is added with a pair of punch-dies at the spare space of one of the two rows of holes, and by adjusting relevant parameters, the whole punch-dies can be arranged in symmetry, so the drawing force can be even; therefore sheet material of the fin can be drawn by even forces, thus avoiding local crinkling and distortion.

Description

The anti-corrugated structures of thin material punching press Stretching die
Technical field
The utility model belongs to the pressure processing technology field in the machine building industry, relates to the structure of cold punching die, and more particularly, the utility model relates to the anti-corrugated structures of a kind of thin material punching press Stretching die.
Background technology
At present, in existing air-condition heat exchanger fin diel, owing to need to realize high flange, and material thickness is very thin, the wrinkling distortion of inevitable generation, traditional moulds mostly takes to strengthen measure such as thrust reducing wrinkling deflection, but the method for some because the inhomogeneous local wrinkling distortion that produces of gravitation of extending has certain limitation, can't implement.
Below in conjunction with this Figure of description the air-conditioning exchanging air fin punching press Stretching die structure that prior art adopted is briefly introduced:
Extend when arranging by certain columns, during the punching punch-die, according to the requirement of fin sheet type, the first step of be everlasting mould first row and last row is extended and the room occurred, when mold integral move, certainly will produce the power inequality of extending, and draws and expects wrinkling metaboly.
Be illustrated in figure 1 as two steppings 5 of conventional 16 row and go on foot the mould Pareto diagram of extending, can see since the first step extend first row and last row extend mould not on same start bit, belong to unsymmetric structure, in the process of extending at the beginning, will cause the heterogeneity buckling deformation to punching press material production asymmetric stresses.
The utility model content
Problem to be solved in the utility model provides the anti-corrugated structures of a kind of thin material punching press Stretching die, its objective is when preventing to approach the material punching press extends to produce fold because of unbalance stress.
To achieve these goals, the technical scheme that the utility model is taked is: this thin material punching press Stretching die that is provided is prevented corrugated structures, the punching press of distribution multiple row and the hole of extending on the strip material of institute's punching press, columns is an even number, and each row is staggered, be arranged in the two row holes at thin material edge at described punching press Stretching die, its original position is according to row of queueing discipline atresia, if balance position, the hole of the original position of itself and described another row is symmetrically distributed, at described balance position, establish a pair of stabilizer tab die of extending, contact with the strip material.
The described stabilizer tab die of extending is the extend punch and the die of extending, and is the coaxial line distribution.
The utility model adopts technique scheme, increase by one group of punch-die on the room of the wherein row in two row holes, edge, adjust relevant parameter, whole punch-die is arranged presented symmetrical structure, reach the even purpose of the stress of extending, make the fin band material power of being extended even, avoided the generation of local wrinkling distortion.This structure is not the required setting of extending, and only is for equilibrium stress, and structure also can be simplified.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is the structural representation of the mould of extending in the related prior art of this specification background technology;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the cross-sectional schematic of the punch-die structure of extending shown in Fig. 2.
Be labeled as among the figure: the punch of 1, extending, 2, the die of extending, 3, balance position.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 2, Fig. 3, the utility model are the anti-corrugated structures of a kind of thin material punching press Stretching die, the punching press of distribution multiple row and the hole of extending on the strip material of institute's punching press, and columns is an even number, and each row is staggered.Be illustrated in figure 2 as two steppings 5 of 16 row and go on foot the mould Pareto diagram of extending, if press the number equal distribution in same column hole, the room will inevitably occur, thin material can produce fold because of unbalance stress when punching press is extended.
In order to solve the problem that exists at the described present known technology of the background technology part of this specification and to overcome its defective, when preventing that the punching press of thin material from extending, realization produces the purpose of fold because of unbalance stress, the technical scheme that the utility model is taked is: this thin material punching press Stretching die that is provided is prevented corrugated structures, be arranged in the two row holes at thin material edge at described punching press Stretching die, its original position is by row of queueing discipline atresia, if balance position 3, the hole of the original position of itself and described another row is symmetrically distributed, at described balance position 3, if a pair of stabilizer tab die of extending contacts with the strip material.
The described stabilizer tab die of extending is the extend punch 1 and the die 2 of extending, and is the coaxial line distribution.
Fig. 2 is after the utility model improves design, two steppings 5 of 16 row go on foot the mould Pareto diagram of extending, its structure is: the start bit that is positioned at first row increases emptily a pair of punch-die of extending promptly extend shown in the figure punch 1 and the die 2 of extending, whole punch-die is arranged presented symmetrical structure, reach the even purpose of the stress of extending, reduced distortion and taken place.
Fig. 3 is the cutaway view of said structure.The expressed punch 1 and the die 2 of extending of extending not is the required setting of extending among the figure, only is equilibrium stress, and structure also can be simplified.
The utility model increases by one group of punch-die on the room by the wherein row in two row holes, thin material edge, adjusts relevant parameter, makes the fin band material power of being extended even, has avoided the generation of local wrinkling distortion.This structure is not the required setting of extending, and only is for equilibrium stress, and structure also can be simplified.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
