It should be noted that corresponding first cavity plate 501 and second is recessed respectively for the first guide plate 401 and the second guide plate 402
Mould 502, wherein the first cavity plate 501 and the upper surface of the second cavity plate 502 are respectively arranged with groove, for placing the first guide plate 401
With the second guide plate 402, the height of the first guide plate 401 and the second guide plate 402 can be adjusted, is easy to the tune of shaving die
It is whole.
In the present embodiment alternative, fixed plate 1000 is fixed on the lower surface of upper bolster 100, and fixed plate in inverted L-shaped
The vertical slot being engaged with the first guide plate 401 is provided with 1000；Prevent in positioning and mold closing, the interference of fixed plate 1,000 first
Guide plate 401 is slided up and down, therefore sets vertical slot, is slided up and down for the first guide plate 401 in vertical slot.
It should be noted that the width of vertical slot is slightly larger than the width of the first guide plate 401, the first guide plate 401 can be made to exist
Vertical slot is slided up and down.
It should be noted that inverted L-shaped fixed plate 1000 includes first panel and second panel, the wherein face on vertical direction
Plate is that panel in first panel, horizontal direction is second panel, and the lower surface of second panel is set to inclined-plane, the inclined-plane with it is convex
The upper surface of mould 300 is brought into close contact, and the setting on inclined-plane can increase fitting area, improve fastness；And formed beneficial to punch-pin 300
Bevelled punch 300, can reduce cut-out shearing force, can be cut off plate according to quality requirement.
In the present embodiment alternative, locating dowel 301 is detachably arranged in the lower surface of punch-pin 300；The chi of locating dowel 301
It is very little to be adjusted according to shape, size of plate etc., therefore, it can be used to be applicable by changing the locating dowel 301 of different-diameter
Different trimming sizes.
It should be noted that locating dowel 301 includes cylinder and column cap, wherein cavity plate 500, which is internally provided with, accommodates cylinder
Hole, column cap is removably connected with cylinder, so need to only adjust the size of column cap diameter, it is possible to regulation shearing size.
It should also be noted that, the diameter length of locating dowel 301 is less than the length of the width of punch-pin 300, therefore positioning
After post 301 is positioned, plate can be cut off by punch-pin 300.
In the present embodiment alternative, spring 800, and 800, spring are provided between upper bolster 100 and die shoe 200
In upper bolster 100 and the edge of die shoe 200；After stripper 900 is pressed onto plate, the stripper in the presence of spring 800
900 can not continue to descending, prevent plate from moving.
It should be noted that the two ends of spring 800 are connected by connecting cylinder with upper bolster 100 and die shoe 200 respectively,
And the inside of spring 800 is additionally provided with the guide frame that can be stretched up and down, it is to avoid swung during flexible.
It should also be noted that, spring 800 is a kind of using the elastic machine components come work, it is made of elastomeric material
Part is deformed upon under external force, is removed and is restored to the original state again after external force.By stress property, spring 800 can be divided into stretching bullet
Spring, compression spring, torsionspring and flexural spring, by shape can be divided into disk spring, ring spring, flat spring, helical spring,
Valute spring and torsion-bar spring etc., can be divided into cold coiling spring and hot coiling spring by manufacturing process.Common cylinder spring
Due to being simple to manufacture, and various types can be made according to loading conditions, it is simple in construction, thus it is most widely used.The manufacture material of spring
In general should have high elastic limit, fatigue limit, impact flexibility and good heat treatment performance etc., conventional has carbon
Spring steel, alloy spring steel, rustproof spring steel and copper alloy, nickel alloy and rubber etc..The manufacture method of spring has cold coiling method
With hot rolling method.Spring will be suppressed or bead after it has been manufactured, can improve the bearing capacity of spring.
In the present embodiment alternative, the material collecting tank for collecting waste material is provided with backing plate 700, for collecting what is cut off
Waste material.
In the present embodiment alternative, the bottom of die shoe 200 is provided with mold changing wheel 201, is easy to the replacing of mould.
The course of work of shaving die：
When equipment runs trimming, upper bolster 100 is with fixed plate 1000, punch-pin 300, locating dowel 301, stripper 900
When a descending segment distance to the lower surface of locating dowel 301 is slightly less than the upper surface of cavity plate 500, plate conveying is until material side top arrives fixed
Position post 301, upper bolster 100 is with upper mounted plate 1000, punch-pin 300, locating dowel 301, stripper 900 in the first guide plate 401
Continue traveling downwardly, after stripper 900 is pressed onto plate, unloaded in the presence of spring 800 under guide effect with the second guide plate 402
Flitch 900 does not continue to descending, but because the pressure of plate gradually increases, can prevent plate from moving.Set when cope plate reaches
When determining stroke, plate trimming is completed, and waste material is fallen from the gap between the first cavity plate 501, the second cavity plate 502；Then upper bolster
After 100 with fixed plate 1000, punch-pin 300, locating dowel 301, the lifting backhaul of stripper 900 to certain altitude, plate passes through.
Embodiment two
The present embodiment also provides a kind of bead cutter, including above-mentioned shaving die.
The bead cutter, including above-mentioned shaving die, therefore all advantages with above-mentioned shaving die, are using process
