Abstract
The utility model provides a double-station continuous skin punching die for hot extrusion forming of a hollow shaft head, relates to the technical field of dies, and is mainly used for punching a hole bottom continuous skin at another station after a deep hole of the hollow shaft head is formed by hot extrusion on the same press. The double-station punching and connecting skin die for hot extrusion forming of the hollow shaft head comprises a workbench, a connecting body, a punching mill, a punching and connecting skin die, a punch and the like. This cavity spindle nose hot extrusion forming duplex position is towards and is linked skin mould through fixing the grinding apparatus that punches a hole and towards even skin mould on same workstation, and the drift is connected with the connector, can accomplish under the reciprocating motion of press, and punch a hole, towards even skin twice process, does not need new input equipment, low cost, the reliability is high, simultaneously, it is less to dash even skin mould atress, does not need design ejection mechanism, simple structure, makes things convenient for the dismouting, trades the frock cycle short, and the safe risk is little.
Description
Technical Field
The utility model relates to the technical field of dies, in particular to a double-station punching and connecting skin die for hot extrusion forming of a hollow shaft head, which is mainly used for punching and removing a hole bottom connecting skin at another station after a deep hole of the hollow shaft head is formed by hot extrusion on the same press machine.
Background
The hot extrusion process is that metal bar stock is heated to 1100-1200 ℃ high temperature state by an intermediate frequency furnace, transferred to a die cavity of a hot extrusion die, and the material is molded into blank with the expected shape through the interaction of a press machine, a concave-convex die and the material. In addition, because the weight of the workpiece is large, a backward extrusion forming process is adopted, the stress at the bottom of the workpiece is large in the forming process, and an ejection mechanism must be designed for a die, so that the inner hole forming and the skin punching process cannot be completed at one time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a double-station punching and connecting skin die for hot extrusion forming of a hollow shaft head, which has the advantages of convenience in use, strong universality, safety, reliability and low manufacturing cost.
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a cavity spindle nose hot extrusion takes shape duplex position to dash and link skin mould, includes the workstation, a bolt fixed mounting of the upper surface of workstation has and dashes and link skin mould, the left side of linking skin mould is provided with the grinding apparatus that punches a hole, and punches a hole grinding apparatus and workstation fixed connection, the grinding apparatus that punches a hole and dashes and link the inside drift that all is provided with of skin mould, the upper surface cover of drift is equipped with the connector.
Furthermore, workpieces are placed in the punching grinding tool and the punching connecting skin die.
Further, the connecting body is connected with a press machine.
Compared with the prior art, the double-station punching and connecting skin die for the hot extrusion forming of the hollow shaft head has the following beneficial effects:
this cavity spindle nose hot extrusion forming duplex position is towards even skin mould is through fixing the grinding apparatus that punches a hole and towards even skin mould on same workstation, and the drift is connected with the connector, can accomplish under the reciprocating motion of press and punch a hole, towards even skin twice process, does not need new input equipment, low cost, and the reliability is high, and simultaneously, it is less to dash even skin mould atress, does not need design ejection mechanism, simple structure, makes things convenient for the dismouting, and the frock cycle of changing is short, and the safe risk is little.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Wherein, 1, a workbench; 2. a linker; 3. a workpiece; 4. punching a grinding tool; 5. punching a connecting skin die; 6. and (4) punching.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the embodiment of the utility model provides a double-station punching and connecting skin die for hot extrusion forming of a hollow shaft head, which comprises a workbench 1, wherein a punching and connecting skin die 5 is fixedly installed on one bolt on the upper surface of the workbench 1, a punching and grinding tool 4 is arranged on the left side of the connecting skin die 5, the punching and grinding tool 4 is fixedly connected with the workbench 1, punches 6 are respectively arranged inside the punching and grinding tool 4 and the punching and connecting skin die 5, and workpieces 3 are respectively placed in the punching and grinding tool 4 and the punching and connecting skin die 5. The upper surface of the punch 6 is sleeved with the connecting body 2, the connecting body 2 is connected with a press machine, when the punching machine works, a workpiece 6 is firstly placed into a punching die 4, after punching is finished, the press machine lifts the connecting body 2 and the punch 6, then the punched workpiece 6 is transferred into a continuous punching die 5, meanwhile, the workpiece 6 to be punched in the previous process is transferred into the punching die 4, and the press machine downwards presses the connecting body 2 and the punch 6 to finish the punching and continuous punching processes at one time. And then the press machine lifts the connecting body 2 and the punch 6, takes out the punched and connected workpiece 6, and repeats the steps to continuously finish the processing of the workpiece 6.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
