Background
The liftout floating block of the stamping die automatically lifts the workpiece upwards after the workpiece is stamped and processed so as to discharge the workpiece; the multi-station production of the punched parts is realized, and the workpieces can be clamped by the clamping hand more easily due to the floating lifting discharge.
The liftout buoyancy lift piece of current press die adopts a plurality of buoyancy lift springs and sets up wear-resisting baffle through the lateral wall and lead the buoyancy lift, and not only the structure is heavy, and processing manufacturing cost is high, and buoyancy spring strength pre-compaction strength is few moreover for the part is beated easily.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the material ejecting and floating block structure of the stamping die is simple in structure and stable in floating.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows: the liftout buoyancy lift block structure of press die, including the mounting hole of setting in the die holder of press die, the activity is equipped with the buoyancy lift guide post in the mounting hole, and the lower part of buoyancy lift guide post is inlayed and is equipped with single nitrogen spring, and single nitrogen spring central line and buoyancy lift guide post central line coincide, buoyancy lift guide post top detachably are equipped with the buoyancy lift piece, and buoyancy lift guide post top surface is equipped with two at least connection locating pins that set up side by side, connects the locating pin embedding in the buoyancy lift piece, be equipped with the shaping portion that corresponds the corresponding part appearance of shaping back work piece on the buoyancy lift piece, buoyancy lift guide post side is equipped with prevents changeing the stopper, and the mounting hole pore wall is equipped with and prevents changeing stopper matched with vertical spacing groove.
Preferably, the buoyancy lifting block is detachably connected with the buoyancy lifting guide column through a connecting bolt.
As a preferred scheme, a pulling part threaded hole which is vertically communicated and used for installing a pulling part bolt is formed in the anti-rotating limiting block.
As a preferable scheme, an installation plane is arranged on the side surface of the buoyancy lifting guide column, and the anti-rotation limiting block is connected to the installation plane.
As a preferred scheme, angle guiding inclined planes are respectively arranged between the outer surface of the anti-rotation limiting block, which is far away from the buoyancy lifting guide column, and the two side surfaces of the anti-rotation limiting block.
As a preferable scheme, a positioning piece for positioning the single nitrogen spring is arranged in the mounting hole of the lower die base.
The invention has the beneficial effects that:
the material-ejecting floating block of the stamping die has a simple structure, reduces the processing cost of die parts, is stable and reliable in floating, is beneficial to realizing multi-station production of parts, has a small volume, and is convenient for clamping and conveying materials by a manipulator during multi-station production; the lifting block force source of the ejection of the stamping die is a single nitrogen spring, the lifting force is large, the gravity center is balanced, and the floating material is prevented from jumping.
Because the anti-rotation limiting block is provided with a vertical through pulling threaded hole for installing a pulling bolt, when the nitrogen spring is damaged, the floating block can be taken out by penetrating the pulling bolt in the pulling threaded hole.
Because the side surface of the buoyancy lifting guide post is provided with the anti-rotation limiting block, and the hole wall of the mounting hole is provided with the vertical limiting groove matched with the anti-rotation limiting block, the buoyancy lifting block can be effectively prevented from rotating in the lifting process.
Because the anti-rotation limiting blocks are respectively provided with the angle guiding inclined planes between the outer surface far away from the buoyancy lifting guide post and the two side surfaces, the up-and-down movement precision of the buoyancy lifting blocks is ensured, and the processing difficulty of the limiting grooves matched with the anti-rotation limiting blocks is reduced.
Because the locating piece for locating the single nitrogen spring is arranged in the mounting hole of the lower die base, the installation is more stable.
