Description
Technical field
The utility model relates to a kind of fragment-free track slab locating piece does not have the scrap (bridge) blanking die.
Background technology
The fragment-free track slab locating piece is the location stressed member when being used for the high speed railway fragments-free track slab laying; Be fixed on the fragment-free track slab bottom surface; Four jiaos of sides, each fragment-free track slab bottom surface are provided with each locating piece, guarantee when fragment-free track slab pavement is located adjustment not by adjuster extrusion damage track plate.
Fragment-free track slab locating piece sheet metal component adds man-hour at stamping-out; Generally the sheet material billot is become the plate blank of certain appearance and size shape with the blanking die stamping-out on punch press; Blank is middle and have 2 holes that the position dimension requirement is arranged, and at last the plate blank is bent into the locating piece part of required form size.The weak point that existing blanking die exists is that stamping-out efficient is not high, and sheet material billot utilization rate is low.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of fragment-free track slab locating piece not have the scrap (bridge) blanking die, and stamping-out efficient is high, can effectively utilize the sheet material billot.
Realize the utility model goal of the invention technical scheme:
A kind of fragment-free track slab locating piece does not have the scrap (bridge) blanking die; Comprise blanking die and blanking punch; It is characterized in that: blanking punch is positioned at the below of blanking die, is provided with the knockout plate that matches with blanking punch in the blanking die, and knockout plate blanking die relatively slides up and down.
Above blanking die; Be provided with piercing punch fixed head, cope match-plate pattern from the bottom to top successively; Blanking die, piercing punch fixed head and cope match-plate pattern are fixed; Be fixed with piercing punch on the piercing punch fixed head, piercing punch vertically passes knockout plate, and the bottom surface of piercing punch is concordant with the bottom surface of blanking die; The corresponding punching concave die hole that is provided with on the blanking punch.
The below and the lower bolster of blanking punch are fixed, and have the punched scrap material spilling hole on the lower bolster.
The outside of blanking punch has been horizontally disposed with die pad, is provided with elastic caoutchouc between die pad bottom surface and the lower bolster end face.
One end of die pad is provided with sheet material billot location-plate.
The knockout plate top is connected to knockout rod, and knockout rod vertically passes piercing punch fixed head and cope match-plate pattern.
The width of blanking punch is greater than the width of sheet material billot, and the length of blanking punch is greater than the length of plate blank.
The beneficial effect that the utlity model has:
Different with prior art, the mold integral structure of the utility model adopts the design of upside-down mounting mould structure, blanking die up, blanking punch below, guarantee directly being discharged on the plate blank from the lower bolster material spilling hole by punched scrap, effectively improve stamping-out efficient.The width of blanking punch is greater than the width of sheet material billot; Can realize that sheet material billot both sides are not had the scrap (bridge) requirement; Improve the utilization rate of sheet material billot, saved blanking punch, die both sides stamping-out simultaneously, protruding, die blanking blanking pressure when reducing blanking sheet material; And make blanking punch, these two sides of die not influenced by the size of blanking part size, can reduce the influence of blanking part to die life.The length of blanking punch can realize that greater than the length of plate blank the sheet material billot is not had the scrap (bridge) requirement along long side direction, has saved raw material; Improve utilization rate of raw materials; Saved blanking punch, die trailing flank stamping-out simultaneously to sheet material, protruding, die blanking blanking pressure when reducing blanking, simultaneously; Make blanking punch, die trailing flank not influenced by the size of blanking part amount, can reduce the influence of blanking part die life.

The specific embodiment
Like Fig. 1, shown in Figure 2, blanking punch 14 is positioned at the below of blanking die 7, and the width of blanking punch 14 is greater than the width of sheet material billot, and the length of blanking punch is greater than the length of plate blank.Be provided with the knockout plate 8 that matches with blanking punch 14 in blanking die 7 die cavities, knockout plate 8 blanking die 7 relatively slides up and down.Above blanking die 7, be provided with piercing punch fixed head 9, cope match-plate pattern 10 from the bottom to top successively, cope match-plate pattern 10 is fixing with die shank 13 through screw 22.Blanking die 7, piercing punch fixed head 9 are fixed with cope match-plate pattern 10 through alignment pin 16, screw 17.Knockout plate 8 tops are connected to knockout rod 12, and knockout rod 12 vertically passes piercing punch fixed head 9 and cope match-plate pattern 10.Be fixed with piercing punch 11 on the piercing punch fixed head; Piercing punch 11 vertically passes knockout plate 8; The bottom surface of piercing punch 11 is concordant with the bottom surface of blanking die 7; The top of piercing punch is provided with piercing punch backing plate 21, and piercing punch backing plate 21 is embedded in the cope match-plate pattern 10, the corresponding punching concave die hole that is provided with on the blanking punch 14.
The below of blanking punch 14 is fixing with lower bolster 1 through screw 18 and alignment pin 19, has the punched scrap material spilling hole on the lower bolster 1.The outside of blanking punch 14 has been horizontally disposed with die pad 4, and die pad 4 is fixing with lower bolster 1 through screw 2 and nut 3, is provided with elastic caoutchouc 5 between die pad bottom surface and lower bolster 1 end face.Sheet material billot location-plate 20 is fixed through a screw 15 and an end of die pad 4, and alignment pin 6 and die pad 4 secure fit play the guide-localization effect to the sheet material billot when work.Blanking punch fastening block 23 is close to lower bolster 1, blanking punch 14 through alignment pin 24 and is fixed together, the outside tension influence in both sides when blanking punch 14 pours waste material in the centre when guaranteeing to overcome work.
