Description

Sheet workpiece stamping die structure with unloading mechanism used in small space

Technical Field

The utility model relates to a mould, especially a sheet metal work piece stamping die structure of shedding mechanism with little space uses.

Background

The die for punching the through hole on the sheet workpiece comprises a punch holding plate positioned above, a punch connected with the punch holding plate, a concave die plate positioned below and a concave die insert embedded on the concave die plate, wherein the concave die insert is provided with a concave die hole matched with the end of the punch, a stripper plate is further arranged between the punch holding plate and the concave die plate, and a discharge spring is arranged between the stripper plate and the punch holding plate. The die with the structure has a complex structure, needs an integral stripper plate, needs an insert block on the stripper plate, occupies a large die space, has a long punch, is poor in precision, strength and stability, is easy to bite, and is high in die cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, occupation space are little, can shorten drift length, improve the punching press precision, improve drift intensity and stability, reduce the mould cost have the sheet metal work piece stamping die structure of shedding mechanism that little space used.

The utility model discloses a sheet metal work piece stamping die structure with shedding mechanism that little space used, including the drift holding plate that is located the top, the drift that meets with the drift holding plate, the die board that is located the below, inlay the die insert on the die board, there is the die hole with drift end assorted on the die insert, it is equipped with the seat of unloading to overlap in drift lower part outside cover, the seat of unloading upper end is fixed below the drift holding plate, the drift muffjoint is in the drift lower extreme outside, the telescopic upper portion of drift is located the seat of unloading inner chamber, there is outer edge drift sleeve upper end, be equipped with the spring in the seat of unloading, the upper end top of spring is leaned on below the drift holding plate, the lower extreme top of spring is leaned on drift sleeve up end, the drift sleeve presses below its outer edge under the effect of spring on the inboard step of unloading seat lower extreme.

The utility model discloses a sheet metal work piece stamping die structure with shedding mechanism that little space used, owing to cancelled a monoblock stripper and inserted, utilize unloading seat and drift sleeve and spring to constitute shedding mechanism, have simple structure, occupation space is little, can shorten drift length, improve the punching press precision, improve drift intensity and stability, reduce the advantage of mould cost.

Detailed Description

As shown in fig. 1 and 2: the utility model discloses a sheet metal work piece stamping die structure with shedding mechanism that little space used, including the drift keeper 1 that is located the top, with drift keeper 1 the drift 7 that meets, the die board 2 that is located the below, inlay the die 5 of inserting on die board 2, have on the die insert 5 with 7 end assorted die holes 10 of drift. The outer side of the lower part of the punch 7 is sleeved with a discharging seat 3, and the upper end of the discharging seat 3 is fixed below the punch retaining plate 1 through a bolt 8. The punch sleeve 11 is sleeved outside the lower end of the punch 7. The upper part of the punch sleeve 11 is positioned in the inner cavity of the discharging seat 3, and the upper end of the punch sleeve 11 is provided with an outer edge 12. A spring 6 is arranged in the discharging seat 3, the upper end of the spring 6 is propped against the lower surface of the punch retaining plate 1, and the lower end of the spring 6 is propped against the upper end surface of the punch sleeve 11. The punch sleeve 11 is pressed under the outer edge 12 thereof against the step on the inside of the lower end of the stripper seat 3 by the spring 6. When in punching, a workpiece 4 is placed on the concave die plate 2, the punch holding plate 1 moves downwards under the driving of the punching machine, the lower end of the punch 7 punches the workpiece 4, and the lower end of the punch 7 enters the concave die hole 10 to punch a through hole on the workpiece 4. The lower end face of the punch sleeve 11 is just pressed on the workpiece 4 during punching, the spring 6 is compressed at the moment, a gap 9 is formed between the outer edge 12 and the inner side step of the lower end of the unloading seat 3, the punch sleeve 7 and the unloading seat 3 move upwards when the holding plate 1 starts to move upwards, the punch sleeve 11 is temporarily fixed under the action of the spring 6, the gap 9 is gradually reduced until the gap is 0, the punch sleeve 11 starts to move upwards, and the punch 7 and the workpiece 4 are separated from each other and are demolded in the process of reducing the gap. The punching head has the advantages of simple structure, small occupied space, capability of shortening the length of the punching head, improving the punching precision, improving the strength and stability of the punching head and reducing the cost of a die.
