Abstract
The utility model relates to an electrolytic capacitor aluminum shell drawing die with a cut structure. In order to solve technical problems, the drawing die can more effectively use an aluminum shell belt material and has the characteristics of high quality of a punched product, high production efficiency and low cost. The technical scheme is that the electrolytic capacitor aluminum shell drawing die with the cut structure comprises a male die and a female die, wherein the male die is fixedly arranged on an upper die base; the female die is fixedly arranged on a lower die base; a row of continuous male die is formed by arranging two to seven drawing male dies, anti-explosion groove male dies, shaping male dies and cut male dies; and a row of female die holes which are adapted to each male die up and down and correspond to each male die one by one are formed in the female die. The electrolytic capacitor aluminum shell drawing die is characterized in that a cutting die is also arranged at the front end of the drawing die and comprises a processing knife and a knife blade female die which are respectively positioned on the upper die base and the lower die base and are matched with each other. The knife blade of the processing knife faces the part between two adjacent impact areas on the aluminum shell belt material.
Description
Technical field
The utility model relates to a kind of cupping tool of making aluminium shell of capacitor, the specifically notch features of Electrolytic Capacitor Aluminum Shell Continuous Strip Material Drawing Die.
Background technology
Polarized capacitor aluminum case is the cylindrical shell of an end opening; The general making aluminium casing with belt material that adopts sheet is made through after the multi-step forming processes by the aluminum hull Drawing Die.Band material by planar shaped becomes cylindrical shell, and deflection (usually representing with the pull and stretch ratio) is very violent; For avoiding surface of shell the situation of quality fault even cracking to occur, usually need to progressively carry out the each deep-drawing deformation amount control of deep-drawing deformation (namely passing through one by one the punching press pull and stretch of a plurality of concave-convex molds) within the specific limits by multiple working procedure.Nonetheless, the making aluminium casing with belt material deep-drawing deformation can only be controlled within the specific limits (height of cylindrical shell is 1.5 times with the pull and stretch of diameter ratio), otherwise can produce the quality fault.
On the other hand, be positioned at part outside the stamped area (i.e. zone between 2 adjacent pull and stretch concave-convex molds) on the making aluminium casing with belt material, through becoming tailing behind the punching press pull and stretch.This part band material can produce a certain amount of deep-drawing deformation (have a certain amount of band material by pull and stretch in cylindrical shell) in punching course, be used for replenishing the needs of housing molding; But because the drawing pressure that the bears making aluminium casing with belt material part in the stamped area, so the additional help during for housing molding is little.
Summary of the invention
The purpose of this utility model provides a kind of improvement of aluminium shell of capacitor Drawing Die, and this Drawing Die should be able to more effectively be utilized making aluminium casing with belt material, has to improve the characteristics that punching out product quality, production efficiency are high, cost is low.
The technical scheme that the utility model proposes is:
Polarized capacitor aluminum case Drawing Die with notch features, comprise the punch that is fixed on upper bolster and the die that is fixed on die shoe, 2-7 in the described punch pull and stretch punch and anti-explosion groove punch, shaping terrace die, excision punch are lined up a continuous row, are provided with on the described die and each punch fit and row's die hole one to one up and down; The front end that it is characterized in that this Drawing Die also disposes notch die, and notch die comprises and lays respectively on upper bolster and the die shoe and the technological tool that cooperatively interacts and edge of a knife die.
The edge of a knife of described technological tool is aimed at the in twos position between the adjacent stamped area on the making aluminium casing with belt material.
The beneficial effects of the utility model are: because the part punching out that is positioned at outside the stamped area at making aluminium casing with belt material first goes out otch (incision is resisted the holdback force that stretches and significantly reduced), when each step of subsequently punching out and pull and stretch aluminum hull, the band material at this position just can be replenished by deep-drawing deformation and enter (otch increases gradually) in the cylindrical shell; Thereby can make the product (pull and stretch ratio can reach 1.8-2.0 doubly) of higher pull and stretch ratio.In addition, also reduced the fraction defective of product, so that the quality of product is more stable.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is the structural representation of the notch die in the utility model.
Fig. 3 is the structural representation of making aluminium casing with belt material in the punching out process.
The specific embodiment
Among the embodiment shown in Figure 1: this polarized capacitor aluminum case Drawing Die, upper bolster is fixed wtih punch, die then be fixed on the die shoe and with one by one corresponding configuration of punch.Described punch comprises 2-7 pull and stretch punch and anti-explosion groove punch, shaping terrace die, excision punch, lines up a continuous row; And be provided with on the die with each punch fit and up and down one to one one row die hole.Said structure is all identical with existing polarized capacitor aluminum case Drawing Die.
Improvement of the present utility model is that the front-end configuration in this Drawing Die has notch die; This notch die comprises and is positioned at technological tool 3 on the upper bolster 2 and is positioned at edge of a knife die 4 on the die shoe 1.Technological tool is also corresponding suitable one by one up and down with edge of a knife die, and large I is specifically selected to determine as required.In the notch die structure (being the left apparent direction schematic diagram of Fig. 1) that Fig. 2 shows as can be known: punch and die have 2 rows, also can determine as required the row of punch and die.
It is upper in the part between the adjacent stamped area 6 in twos that the edge of a knife of described technological tool is aimed at making aluminium casing with belt material U, and the otch 7 that usually forms just in time is positioned at the centre of adjacent in twos stamped area, and (shown in Figure 3 only is the position of otch 7; Shape after the otch distortion enlarges is omitted).
Claims (2)
1. the polarized capacitor aluminum case Drawing Die that has notch features, comprise the punch that is fixed on upper bolster (2) and the die that is fixed on die shoe (1), 2-7 in the described punch pull and stretch punch and anti-explosion groove punch, shaping terrace die, excision punch are lined up a continuous row, are provided with on the described die and each punch fit and row's die hole one to one up and down; The front end that it is characterized in that this Drawing Die also disposes notch die, and notch die comprises and lays respectively on upper bolster and the die shoe and the technological tool that cooperatively interacts (3) and edge of a knife die (4).
2. the polarized capacitor aluminum case Drawing Die with notch features according to claim 1, the edge of a knife that it is characterized in that described technological tool are aimed at position between the in twos adjacent stamped area (6) on the making aluminium casing with belt material.
