SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a thin wall spare forming device replaces the mode of bending behind the original ordinary die mould, and the device counter weight side piece has reduced the frictional force in the mould and the product outside, has alleviateed the mar efficiency simultaneously and has promoted greatly.
Thin wall spare forming device include: a lower die holder; the fixing plate is fixed on the lower die base and is provided with an accommodating cavity; the pressure-bearing mechanism is arranged in the accommodating cavity and is movably connected with the accommodating cavity; the pressure-bearing mechanism comprises two counterweight side blocks symmetrically arranged in the accommodating cavity, and the side walls of the counterweight side blocks are movably connected with the accommodating cavity; the pressure-bearing female die is arranged between the two counterweight side blocks and is movably connected with the counterweight side blocks; the counterweight side block is characterized in that one end of the bottom of the counterweight side block is provided with a circular arc-shaped protruding part, the other end of the counterweight side block is provided with an inclined plane which inclines upwards from the circular arc-shaped protruding part, the circular arc-shaped protruding part is abutted against the fixed plate, and the bottom of the accommodating cavity is provided with a cavity for the circular arc-shaped protruding part to move.
Preferably, a positioning block is arranged on the fixing plate on one side of the pressure-bearing female die.
When the workpiece is placed, one end of the workpiece is abutted to the positioning hole.
Preferably, a base plate is arranged between the fixing plate and the lower die base, and the arc-shaped protruding part is abutted to the base plate.
The use principle and the process are as follows: when in the initial position, the two counterweight side blocks naturally cling to the pressure-bearing female die due to self weight; after the workpiece is placed, the bottom of the workpiece is attached to the pressure-bearing female die, and the two sides of the workpiece push the counterweight side blocks to the two sides; during punching press, the terrace die that is located the pressure-bearing die top moves down, at first through work piece and pressure-bearing die butt, extrudees the shaping of buckling, and the extrusion is buckled and is driven work piece and pressure-bearing die and is moved down along counter weight side piece in-process, because counter weight side piece bottom is equipped with convex bellying and inclined plane, counter weight side piece pressurized will follow base angle internal rotation, pastes tightly with the pressure-bearing die once more, when making the work piece accomplish the shaping of buckling, the both sides turn-ups compress tightly the binding off.
The utility model has the advantages that: through setting up counter weight side piece and pressure-bearing die, realize the turn-ups in both sides when making the work piece shaping of buckling and compress tightly the binding off, the device counter weight side piece has reduced the frictional force in mould and the product outside, has alleviateed the mar efficiency simultaneously and has promoted greatly.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-4, the thin-wall part forming device of the present invention comprises: a lower die holder 1; the fixing plate 2 is fixed on the lower die holder 1, and an accommodating cavity 3 is formed in the fixing plate 2; the pressure-bearing mechanism is arranged in the accommodating cavity 3 and is movably connected with the accommodating cavity 3; the pressure-bearing mechanism comprises two counterweight side blocks 4 which are symmetrically arranged in the accommodating cavity 3, and the side walls of the counterweight side blocks 4 are movably connected with the accommodating cavity 3; the pressure-bearing female die 5 is arranged between the two counterweight side blocks 4 and is movably connected with the counterweight side blocks 4; one end of the bottom of the counterweight side block 4 is provided with a circular arc-shaped bulge 6, the other end of the counterweight side block is provided with an inclined plane 7 which inclines upwards from the circular arc-shaped bulge 6, the circular arc-shaped bulge 6 is abutted against the fixed plate 2, and the bottom of the accommodating cavity 3 is provided with a cavity 8 for the movement of the circular arc-shaped bulge 6. And a positioning block 9 is arranged on the fixing plate 2 at one side of the pressure-bearing female die 5. A base plate 10 is arranged between the fixing plate 2 and the lower die holder 1, and the arc-shaped protruding portion 6 is abutted to the base plate 10.
