Brief description of the drawings
Fig. 1 is the structural representation of the utility model brake block steel back fine blanking die assembly；
The drift of Fig. 2 die assemblies and the partial structural diagram at concave die cavity cutting edge.
Embodiment
Below in conjunction with the accompanying drawings to a kind of structure and work of brake block steel back fine blanking die assembly provided by the utility model
It is described in further detail as principle.
As shown in figure 1, it is a kind of brake block steel back fine blanking die assembly provided by the utility model
Structural representation.The structure of the brake block steel back fine blanking die assembly is formed mainly by the upper mould of setting drift 11
Tool 1, the lower mould 2 provided with cavity plate 21 are formed, wherein, mold 1 includes upper die plate 12 and connected upper baffle plate 13,
The top of upper die plate 12 is used to accept downward fine punching F1, and drift 11 is arranged on the bottom of baffle plate 13；Lower mould 2 includes
Lower mould base 22 and connected lower mold backing plate 23, cavity plate 21 are arranged on the top of lower mold backing plate 23, position by locked mode cage plate 24
Vertical corresponding with drift 11 in the die cavity 211 in cavity plate 21, the inside of die cavity 211 of cavity plate 21 sets the lower die shoe core of vertical movement
25, lower die shoe core 25 accepts upward pretension towing force by bottom plate 26 through lower mold backing plate 23 and lower mould base 22
F2, in the present embodiment, lower die shoe core 25 can be by the one-level stooling 251 in cavity plate 21 and two in lower mold backing plate 23
Level stooling 252 is formed.
Its operation principle is：
（1）The fine blanking die assembly is arranged in forcing press first, upper die plate 12 and the upper hydraulic cylinder of mold 1
Piston rod is connected, and the lower mould base 22 of lower mould 2 is fixed with workbench, and the piston rod of lower hydraulic cylinder is connected with bottom plate 26；
（2）Plate or steel back blank to be trimmed are placed at lower die shoe core 25, hydraulic cylinder in startup, mold 1 is overall
It is descending by quickly turning two sections of speed at a slow speed, until contact steel back blank；
（3）Mold 1 is overall to switch to attack that speed is descending, and the piston rod with hydraulic cylinder at present lifts bottom plate upwards
26, the lower die shoe core 25 being connected with bottom plate 26 provides pretightning force to steel back blank；
（4）The elastic caoutchouc of unloading mechanism, which is pressurized, shrinks back, and drift 11 exposes the die cavity 211 of stripper alignment cavity plate 21；
（5）Steel back blank drift 11 downward fine punching F1 and lower die shoe core 25 upward pretension towing force F2 effect
In the lower die cavity 211 into cavity plate 21, fine-edge blanking is completed, clout is placed in around drift 11；
（6）Mold 1 is overall up, and the downward resilience of elastic caoutchouc of unloading mechanism, stripper is by clout from drift 11
Hit down；
（7）Lower die shoe core 25 ejects steel back fine finished product upwards in the presence of pretension towing force F2.
In a kind of above-mentioned structure of brake block steel back fine blanking die assembly is formed,
--- in order to realize the automatic material returning process described in operation principle, the above-mentioned suit of unloading mechanism 3 is arranged at mould
The drift 11 of the bottom of bottom plate 13, its thickness are not less than the length of drift 11, and unloading mechanism 3 includes the mounting base being sequentially connected
31st, elastic caoutchouc 32 and stripper 33, mounting base 31 and the upper detachable connection of baffle plate 13, are easy to elastic caoutchouc 32 and move back
The maintenance renewal of flitch 33, ensure that punching press, blanking, material returned processing link link up, improves the automaticity of fine-edge blanking,
Meanwhile pressure of the die assembly by downward fine punching F1, upward pretension towing force F2 and elastic caoutchouc 32 in blanking process
Contracting elastic force, the load that fine blanking die assembly is born is reduced, rigid infringement is avoided, extends service life；
--- once placed to realize, three processes（Leveling, back chipping, smart scraping）Synchronous production, improve punching production
Efficiency, the die cavity 211 for meeting for more specifications, requirements of mass production, to be arranged in above-mentioned cavity plate 21 is with being located at upper baffle plate
The lower die shoe core 25 on drift 11, bottom plate 26 on 13 cooperates, and quantity is one or more, improves the performance of enterprises,
Resource utilization is improved, saves the requirement that the energy meets energy-saving and emission-reduction；
--- as shown in Fig. 2 in order to prevent steel back sheet material detrusion area from producing stress concentration, above-mentioned drift 11 and cavity plate
21 die cavity 211 carries out A at the cutting edge of punching press and sets fillet R, and its radius is the 5% to 15% of brake block steel back thickness, cavity plate 21
Cutting edge fillet R postponed generation phase of crackle, the uniformity of metal flow, reduces the change of material in increase detrusion area
Shape degree, delays the time of plastic period and fracture generation, and also has and increase compression and shear surface is squeezed
The effect of light, the steel back fracture euphotic belt after punching ensure more than 95%；
--- different blade clearance T is very big on steel back punching face quality influence, in practice, with blade clearance T increasing
Add, the flatness in steel back punching face, smoothness are decreased obviously, and the gap T of above-mentioned drift 11 and cavity plate 21 is less than brake block steel back
It the 0.2% of thickness, ensure that the tension in steel back plate detrusion area is as far as possible small, compression increase, improve fine-edge blanking
Quality；
--- in order to meet the fine-edge blanking requirement to the steel back sheet material of different-thickness, above-mentioned fine punching F1 is described pre-
1.8 to 2.6 times of tight towing force F2, after this fine blanking die assembly is installed on common hydraulic press, prefastening combination fine blanking technology life
Production significantly improve steel back final product quality, can stamping parts of the fine sheet thickness more than 10 millimeters, and flatness control ±
Within 0.08mm, the angle of collapsing on punching face is highly the half of common stamping part, and steel back punching face can form hardened layer, and it is flat
Equal hardness is 2 times of original matrix, even up to 2.5 times, fullys meet main engine plants' auxiliary products requirement（International OE products mark
Alignment request）, by the consistent accreditation of main frame manufacturer both at home and abroad, add product competitiveness.
