Description

A kind of high-strength plate stringer the left and right parts using one die shaping dies
Technical field
The utility model relates to a kind of high-strength plate stringer the left and right parts using one die shaping dies, belong to automobile component processing mold skill Art field.
Background technique
In auto manufacturing, for automobile lightweight, the utilization rate of automobile high strength steel plate on the body of a car is more next It is higher.Tool and Die Technology is the core technology of modern punching production, and automobile high-strength plate stringer is part important on automobile.For big Type has shape high-strength plate stringer forming, is implemented separately on two sets of independent molds under normal conditions.In order to reduce mould Have development cost, mold tricks should be reduced to the greatest extent, simplifies Mold Making technique.
High-strength plate stringer will will appear more serious rebound and twisted phenomena in forming process, thus for it is large-scale, With shape high-strength plate stringer forming mould, it is especially desirable to consider the convenience and reliability of its rebound and distortion adjustment.Large-scale, band Have shape high-strength plate stringer product, be that left and right part respectively uses a set of shaping dies under normal conditions, it is carried out again after forming deburring, Punching, shaping, side shaping.In this case, different according to the complex situations of stringer, under normal circumstances, left-right longeron needs altogether 6-10 mold could be completed.Conventionally, die manufacturing cost is high, and operation quantity is more, and it is more to occupy press resource.
Utility model content
The utility model needs two sets for the processing mold of existing high-strength plate stringer, and cost of manufacture is high, waste of material Serious problem provides a kind of high-strength plate stringer the left and right parts using one die shaping dies.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of high-strength plate stringer the left and right parts using one die forming Mold, including upper die holder and lower die holder, are characterized in that, punch-pin fixing seat are fixedly mounted on the upper die holder, convex The two sides of the lower section of model fixing seat are provided with insert mounting groove, and punch insert is mounted on insert mounting groove, the lower die holder With mounting groove, the first die fixed seat and the second die fixed seat, the first die plate insert peace are installed on the side wall of mounting groove On the fixed step of the first cavity plate on the first die fixed seat top, the second die plate insert is mounted in the second die fixed seat On the fixed step of second cavity plate in portion, bottom knockout body is provided between the first die fixed seat and the second die fixed seat, under Lower push rod is fixed with below liftout body, lower push rod passes through the bottom of lower die holder.
Based on the above technical solution, the utility model is to reach the stability of the convenience and equipment that use, Following improvement can also be made to above-mentioned technical solution:
Further, mandril cushion block is provided at the top of the lower push rod, lower push rod passes through mandril cushion block and bottom knockout body It is fixed.
Further, it is provided with fixing groove on the outside of the lower die holder, has bolt hole in fixing groove.
Further, section is provided in second die fixed seat for L-shaped inside groove, on the side wall of L-shaped inside groove It is provided with the bolt hole for being fixed on lower module, is provided on the side wall of the other side of inside groove for fixing the second female die embedding The through-hole of block.
Further, the positioning protrusion of punch-pin fixing seat is provided on the upper die holder.
Further, block key is provided on the upper die holder.
Utility model has the advantages that high-strength plate stringer forming mold, is the spy of mirror symmetry according to high-strength plate or so Point, because mold is set as dismountable form, squeeze left high-strength plate stringer post-processing right high-strength plate stringer when, only By shaped portion reversing of position dismountable in mold, so that it may carry out the extruding of the high-strength plate stringer of the other side.Simultaneously also It has the advantage that
1, by doing insert exchange to the asymmetric region of left-right longeron, realize completed in one set of die left-right longeron at Shape mould shares: reducing a set of shaping dies.
2, stringer both ends arc area, is easy to happen rebound and distortion, installs dismountable insert in this region: facilitating The adjustment of stringer rebound and distortion.
3, mould structure is simple, and insert is easy to change: save the cost has higher practicability.
4, it is that side is fixed that forming terrace die insert and die plate insert, which are secured to seat: product opening size adjusts convenience.
5, forming terrace die bottom is spaced apart 2 millimeters: suppressing to the formation of stringer fillet, convenient for control stringer opening rebound.
