In the big equipment of bit comparison, rubber track plate is more with the equipment of small tonnage.
The creeper tread of steel can be divided into：Excavator plate, bull-dozer plate, both are the most frequently used, using shaped steel as former material
Material.The creeper tread processing process of shaped steel is usually：Utilize cutting of material, punching, heat treatment, alignment and spray painting.
When being punched out operation to creeper tread, because material rigidity and the toughness of creeper tread are higher, therefore in punching
When, the drift of common die easily deforms the phenomenon of damage.
Utility model content
The purpose of this utility model is：A kind of crawler plate punching die is provided, the creeper tread of shaped steel material can be rushed
Hole operation, pierce punch are hardly damaged, and can ensure punching quality.
To achieve these goals, the utility model provides following technical scheme：
A kind of crawler plate punching die, including stack gradually the upper bolster, upper padding plate, drift of setting from top to bottom and fix
Plate, stripper plate, concave template, lower bolster and die shoe；The upper bolster lower end is provided with correcting locating piece, the correcting positioning
Block is internally provided with the first nitrogen spring, and the both sides of upper bolster lower end punch fixing plate are provided with the second nitrogen spring, institute
State upper padding plate lower end and be provided with pierce punch, the pierce punch is parallel with correcting locating piece, is set inside the pierce punch
Thimble is equipped with, the hardness of the upper end of the pierce punch is higher than the hardness of lower end, and the thimble is coaxially disposed with pierce punch, institute
The lower end for stating stripper plate is provided with guide pad, limit for height block is provided with the both ends between the stripper plate and concave template, under described
The upper end of backing plate is provided with the 3rd nitrogen spring.
Further, the correcting locating piece vertically runs through upper padding plate and punch fixing plate, first nitrogen spring
Upper end is in contact with the bottom surface of upper bolster, and the pierce punch vertically runs through punch fixing plate, and the 3rd nitrogen spring is vertical
It is connected through the bottom of concave template with the upper end and stripper plate of limit for height block and the 3rd nitrogen spring.
Further, the position of the correcting locating piece and pierce punch is corresponding with stripper plate, the pierce punch
Lower edge at be provided with taper face.
The beneficial effects of the utility model are：A kind of crawler plate punching die, by punch fixing plate, correcting locating piece,
The comprehensive use of pierce punch, guide pad and thimble, can be punched out operation to the creeper tread of shaped steel material, under pierce punch
The hardness that end margin is provided with the taper face upper end of pierce punch simultaneously is higher than the hardness of lower end, therefore pierce punch not rapid wear
It is bad, production cost can be reduced, while original dismounting die change drift operation can be avoided, production efficiency is improved, and can protect
Demonstrate,prove punching quality.
Brief description of the drawings
Fig. 1 is a kind of overall structure diagram of crawler plate punching die of the utility model.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
With reference to figure 1, a kind of crawler plate punching die, including stack gradually from top to bottom the upper bolster 1 of setting, upper padding plate 2,
Punch fixing plate 3, stripper plate 4, concave template 5, lower bolster 6 and die shoe 7；The lower end of upper bolster 1 is provided with correcting positioning
Block 8, the correcting locating piece 8 are internally provided with the first nitrogen spring 9, and the both sides of the lower end punch fixing plate 3 of upper bolster 1 are set
The second nitrogen spring 10 is equipped with, second nitrogen spring 10 is used to avoid upper bolster 1 and stripper plate 4 in matched moulds punching course
Between produce rigidity and collide, the lower end of upper padding plate 2 is provided with pierce punch 11, the pierce punch 11 and correcting locating piece 8
Parallel, the pierce punch 11 is internally provided with thimble 15, and the hardness of the upper end of the pierce punch 11 is hard higher than lower end
Degree, for avoid in punch process pierce punch 11 because it is strong collide and external force effect be deformed or fracture it is bad
Phenomenon, so as to greatly improve the service life of pierce punch 11, the thimble 15 is coaxially disposed with pierce punch 11, the thimble
