Description

The movable blade organization of punch level progressive die

Technical field

The utility model relates to electronic component manufacturing equipment field, particularly relates to the movable blade organization of a kind of punch level progressive die.

Background technology

Along with social development, electronic product more New steps is accelerated, and supporting electronic components is progressively produced in enormous quantities towards the standardised generic type, most product structure typings, and spatial limitation, stamping technology also requires constantly to promote and meet the various product structure.

Need to develop according to product structure the diel that meets utilization, and standardized product exists product size setting and structure setting because volume is little, thereby punching press product size is little, strict.The inner molding structure of existing mold can't reach its product design structure and required precision, causes certain technical bottleneck.

The characteristic of punch level progressive die maximum and advantage place can complete whole product Sheet Metal Forming Technology exactly in a mold, and product must have a carrier connecting every one technique, last one punching press completes separating of product and carrier, and normal punching structure is all moving up and down perpendicular to 90 °, horizontal plane of through type.

As shown in Figure 1, this class formation compared with normal stamping products has the structure specificity, product is totally-enclosed shape, the goods support coupled position is closed and blocks at the other end, if continue to adopt the stamping-out mode of upper and lower through type, the product be shaped will certainly be wounded, and the horizontal pusher edge of a knife that industry field is commonly used at present, as shown in Figure 2, can complete the stamping-out action, but laterally advance, be in the situation that complete closed the moving of mould, the product material strip is produced to friction, thereby affect product size, poor and the burr of serious generation stamping-out section, affect the use of product.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

Refer to Fig. 3, the utility model embodiment comprises:

The movable blade organization of a kind of punch level progressive die comprises: stamping-out punching pin 10, middle die-cushion plate 20, middle template 30, patrix ejector pin 41, upper resetting structure 42, counterdie ejector pin 51, lower resetting structure, slide block 60 and take-up housing 70.

Described middle die-cushion plate 20 is connected with middle template 30, and the upper end of described patrix ejector pin 41 is connected with upper resetting structure 42, and is arranged in described middle die-cushion plate 20 and middle template 30, and the lower plane of described middle template 30 is protruded in the upper end of described patrix ejector pin 41.Preferably, the length of the lower plane of the described middle template 30 of the lower end of described patrix ejector pin 41 protrusion is greater than the thickness of product 80.In the present embodiment, the twice of the thickness that the length of the lower plane 31 of the described middle template 30 of the lower end of described patrix ejector pin 41 protrusion is product, be 0.4mm.Described upper resetting structure 42 is a built-in spring, and the restriction by external shell makes the spring original state just in compressive state, has a starting force, and described starting force need be greater than the buoyant strength of counterdie floating block.

Described slide block 60 is arranged in described take-up housing 70, described slide block 60 is connected by position limiting structure with described take-up housing 70, described slide block 60 moves with respect to described take-up housing 70 along the restriction inclined-plane 71 of described position limiting structure, the lower end of described counterdie ejector pin 51 is connected with lower resetting structure, and the upper end of described counterdie ejector pin 51 contacts with the lower surface of described slide block 60; Comprise the edge of a knife 61 on described slide block 60, the described edge of a knife 61 matches with described stamping-out punching pin 10.In the present embodiment, the position limiting structure that described position limiting structure is concavo-convex cooperation.Specifically, on described take-up housing 70, mounting groove is arranged, a spacing inclined-plane 71 is arranged on mounting groove, described slide block 60 1 sides have the structure suitable with described mounting groove, can be arranged in described mounting groove, and move along described restriction inclined-plane 71.Described take-up housing 70 is the monolithic construction of inserting, and can make up effective control of the problems such as blade clearance that the machining accuracy deficiency brings.

In conjunction with shown in Fig. 3 to Fig. 5, the course of work of the movable blade organization of the utility model punch level progressive die is as follows:

Figure 3 shows that original state, the upper surface of described slide block 60 is higher than the upper surface of described take-up housing 70, and described middle template 30 and stamping-out punching pin 10 are above away from described take-up housing 70, and described product 80 is suspended between described slide block 30 and described stamping-out punching pin 10.Figure 4 shows that the state in moving downward, described stamping-out punching pin 10, middle die-cushion piece 20, middle module 30, patrix ejector pin 41 and upper resetting structure 42 move downward, the upper surface of the lower surface of at first described patrix ejector pin 41 and described slide block 30 contacts, the upper surface of the carrier 81 of the lower surface of described middle module 30 and described product 80 contacts, described slide block 60 and described product 80 is stressed moves downward.Figure 5 shows that the matched moulds state, when arriving the matched moulds position, now described carrier 81 just contacts with the upper surface of described slide block 60, and the edge of a knife 61 on described stamping-out punching pin 10 and described slide block 60 matches described product 80 stamping-out from carrier 81 is got off.The carrier 81 that is produced as of time difference is not stopped space by friction texturizing, needs template 30 pressing actions in basis to complete precompressed and carrier location simultaneously.Finally, described stamping-out punching pin 10, middle die-cushion piece 20, middle module 30, patrix ejector pin 41 and upper resetting structure 42 move upward, described slide block 60 is got back to original state under the effect of lower resetting-mechanism 70 and counterdie ejector pin, and described patrix ejector pin 41 is got back to original state under the effect of upper resetting structure 42.
