Abstract
The utility model relates to a knockout device for a tetrastyle metal extrusion forming hydraulic press die. The knockout device for the tetrastyle metal extrusion forming hydraulic press die comprises an upper beam, a lower beam, pilot pistons, sliders and a main cylinder. Four angles of the upper beam and four angles of the lower beam are connected and fixed through the pilot pistons. The pilot pistons are in sliding fit with the sliders. The sliders are driven by the cylinder arranged on the upper beam. Male dies are arranged on the lower end face of the sliders through upper die-sets. The knockout device for the tetrastyle metal extrusion forming hydraulic press die is characterized in that a rapid-knockout plate is arranged below the slides, four angles of the rapid-knockout plate are in sliding fit with the sliders, a through hole allowing the male die to penetrate is arranged in the center of the rapid-knockout plate, each angle of the sliders is provided with a knockout cylinder, and a piston rod of the knockout cylinder is connected with the rapid-knockout plate. When extruding, the main cylinder drives the sliders to move down, and a female die of the lower beam and the male die match with each other to extrude the fire extinguisher tank. After a fire extinguisher tank is extruded, the sliders move up, the knockout cylinder is ejected out, the rapid-knockout plate moves down to push down the fire extinguisher tank which is close to the male die, and knockout is achieved without manual knockout.
Description
Technical field
The utility model relates to a kind of four-column type extruding metal forming hydraulic press, particularly a kind of four-column type extruding metal forming hydraulic press stripper apparatus.
Background technology
When utilizing four-column type extruding metal forming hydraulic press compacting fire extinguisher tank, because the axial length of fire extinguisher tank is larger, after compacting was finished, tank body easily was adsorbed on the formpiston, demoulding difficulty.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of efficiently four-column type extruding metal forming hydraulic press stripper apparatus that is convenient in demoulding.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of four-column type extruding metal forming hydraulic press stripper apparatus, comprise entablature, sill, guide pillar, slide block and master cylinder, on described, four jiaos of sill are connected and fixed by guide pillar, slide block is slidingly matched on the guide pillar, slide block is driven by the master cylinder that is installed on the entablature, formpiston is installed by top mold frame in the slide block lower surface, its innovative point is: the below of described slide block arranges fast stripper plate, four jiaos of described fast stripper plate are slidingly matched with guide pillar, the center of described fast stripper plate has and holds the through hole that formpiston passes through, four jiaos of slide block all are equipped with demoulding oil jar, and the piston rod of described demoulding oil jar is connected with fast stripper plate.
The utility model has the advantage of: during compacting, master cylinder drives slide block down, so that cooperating with former on the sill, formpiston carries out the fire extinguisher tank compacting, after compacting is finished, slide block is up, and demoulding oil jar ejects, and the fire extinguisher tank of being about to be close to formpiston under the fast stripper plate pushes, realize the demoulding, need not the manually demoulding.
Description of drawings
Fig. 1 is the utility model four-column type extruding metal forming hydraulic press stripper apparatus structural representation.
The specific embodiment
As shown in Figure 1, comprise entablature 1, sill 2, guide pillar 3, slide block 4, master cylinder 5, formpiston 6, fast stripper plate 7, demoulding oil jar 8.
Above-mentioned entablature 1, sill 2 four jiaos are connected and fixed by guide pillar 3, the slide block 4 that is slidingly matched on the guide pillar 3, and slide block 4 is driven by the master cylinder 5 that is installed on the entablature 1, and formpistons 6 are installed by top mold frame 9 in slide block 4 lower surfaces.
The below of slide block 4 arranges fast stripper plate 7, the center of this fast stripper plate 7 has and holds the through hole that formpiston 6 passes through, four jiaos of fast stripper plate 7 are slidingly matched with guide pillar 3, and four jiaos of slide block 4 all are equipped with demoulding oil jar 8, and the piston rod of demoulding oil jar 8 is connected with fast stripper plate 7.
Operation principle: during compacting, it is descending that master cylinder 5 drives slide blocks 4, so that formpiston 6 cooperates with former on the sill 2 and carries out fire extinguisher tank and suppress, after compacting is finished, slide block 4 is up, and demoulding oil jar 8 ejects, and the fire extinguisher tank that fast stripper plate is about to be close to formpiston 6 for 7 times pushes the realization demoulding.
