Description
Technical field
The utility model relates to metal trimming and piercing die field, refers to the hot press-formed trimming part punching die of a kind of high-strength steel sheet particularly.
Background technology
Will realize the punching of hypervelocity, the hot press-formed trimming part of high-strength steel sheet, substantially adopt the method for laser cutting, this method will consume a large amount of resources, and efficiency is low in the past; At present, require more and more higher to the collision safety performance of automobile, simultaneously more and more stricter to the restriction of automobile carbon emission amount, therefore, people have to make great efforts a kind of lighter weight, the automobile panel technique that intensity is high again simultaneously.
Under high strength, adopt common mode of colding pressing, the resilience of final molding part and the wearing and tearing etc. of mould are all difficult to solve, create thermoforming high strength martensitic steel and corresponding process forming technology in this case, its application also obtains further development, and hot press-formed what obtain is the bodywork parts of superhigh intensity; Tare can be alleviated; Vehicle body security, comfortableness can be improved; Because thermoforming part has high strength, high rigidity, high-precision performance, therefore subsequent handling, each large parts supplier all adopts the mode of laser cutting to complete the requirement of part to hole and limit.2-4 platform laser cutting machine is equipped with in order to meet thermoforming line needs of working in three shifts, the price of a special laser cutting machine of thermoforming part is 1,000,000 dollars, the part laser cutting of each thermoforming needs special cutting clamper, the price of each special fixture is greater than 200,000 RMB, production cost is too large, length consuming time.
Summary of the invention
The purpose of this utility model is exactly to provide that a kind of structure is simple, easy for installation, the hot press-formed trimming part punching die of the high-strength steel sheet of stable performance.
For achieving the above object, the hot press-formed trimming part punching die of a kind of high-strength steel sheet designed by the utility model, comprise patrix, counterdie and the holding pad being provided with four limited blocks, described holding pad is fixedly connected with patrix by four bolts, described counterdie is provided with die, die locating part, two are provided with the lead of fairlead and block of tossing about, described patrix lower end is provided with deburring insert base, first drift base and the second drift base, described deburring insert base lower end is provided with deburring insert, described first drift base and the second drift base lower end are respectively equipped with the first drift and the second drift, also brute spring is provided with between described holding pad and patrix, it is characterized in that: the cut surface of described deburring insert with treat that deburring part upper surface becomes 5 ° of angles along cut direction, the cutting edge of described deburring insert is provided with the rounding of R0.3mm, the cutting edge of described first drift and the second drift is equipped with the rounding of R0.3 ~ 0.5mm.
The working face of described holding pad is serrated face.
The utility model has the advantage of: the cut surface of deburring insert is set to inclined-plane along cut direction, reduce blanking pressure, and, the cutting edge of deburring insert, the first drift and the second drift is provided with rounding, make cutlery have certain intensity, prevent the sound of sth. throbbing or bursting sword, avoid the loss of mould; The working face of holding pad is serrated face, prevents until trimming and piercing die part play when being subject to stamping-out external force, and its structure is simple, and low cost of manufacture is easy to use, is easy to promote.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The hot press-formed trimming part punching die of high-strength steel sheet shown in figure, comprise patrix 1, counterdie 2 and the holding pad 3 being provided with four limited block 3a, holding pad 3 is fixedly connected with patrix 1 by four bolts 14, counterdie 2 is provided with die 4, die locating part 5, two are provided with the lead 6 of fairlead 6a and block 7 of tossing about, patrix 1 lower end is provided with deburring insert base 8, first drift base 9 and the second drift base 10, deburring insert base 8 lower end is provided with deburring insert 11, first drift base 9 and the second drift base 10 lower end are respectively equipped with the first drift 12 and the second drift 13, brute spring 15 is also provided with between holding pad 3 and patrix 1, the cut surface 16 of deburring insert 11 with treat that deburring part upper surface becomes 5 ° of angles along cut direction, the cutting edge of deburring insert 11 is provided with the rounding of R0.3mm, the cutting edge of the first drift 12 and the second drift 13 is equipped with the rounding of R0.3 ~ 0.5mm, the working face of holding pad 3 is serrated face 3b.
Mould is loaded in 100 tons of crank presses, adjust shut height, counterdie 2 is locked in workbench center place, patrix 1 is fixed on top shoe, top shoe is risen to top dead-centre by opening travel switch, be 1530MPa by tensile strength, treat that mould put into by trimming and piercing die part, both hands are by action button, the top shoe of press drives patrix 1 to decline, the holding pad 3 being positioned at patrix 1 first contacts plate, serrated face 3b thrusts plate slightly, after this brute spring 15 in patrix 1 is compressed, top shoe continues to decline, until the cut surface 16 of deburring insert 11, first drift 12 and the second drift 13 is progressive touches plate and cut, slab interior stress increases to yield limit, plate starts to be separated, top shoe reaches bottom dead centre simultaneously, top shoe will take back top dead-centre by crank, and so forth.
