The integrated device comprises the lower punch, a mold cavity, an upper punch, a lower mold core, an upper mold core, a demolding oil cylinder, an ejector rod and a lower punch seat, wherein through holes are formed in the centers of the lower mold core and the upper mold core; the central through holes of the lower mold core and the upper mold core form the mold cavity; the lower punch is arranged below the lower mold core; the upper part of the lower punch extends into the mold cavity; the upper punch is arranged at the upper part of the upper mold core; the lower part of the upper punch extends into the mold cavity; the lower punch seat is arranged below the lower punch; the ejector rod is arranged below the lower punch seat; a piston rod is arranged in the demolding oil cylinder; and the upper part of the piston rod is fixedly connected with the lower part of the ejector rod. The integrated device is simple in structure and reliable in operation; requirements of a production process can be met; the production and manufacturing cost can be lowered; the weight of the complete device is reduced; the integrated device is low in fault probability; and the maintenance cost is lowered.
Description
Technical field
The present invention relates to low punch and discharging mechanism integrated apparatus in a kind of metal forming equipment.
Background technology
The high speed hot extrusion forming technology is one of new technology that develops rapidly in recent years, applies, and is a kind of few cutting or without the advanced technologies technology of machining.
Existing metal plastic forming device structure more complicated generally needs special-purpose manipulator that the part that machines is pressed from both sides out from discharge opening when discharging, sends into blanking system again; Like this, not only increased the production cost of equipment, and, also increased equipment fault origination point in process of production, improved maintenance cost.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the defects that prior art exists, and provides a kind of simple in structure, low cost of manufacture, low punch and discharging mechanism integrated apparatus in the metal forming of being convenient to the keep in repair equipment.
The technical solution adopted for the present invention to solve the technical problems is: low punch and discharging mechanism integrated apparatus in a kind of metal forming equipment, comprise low punch, die cavity, upper punch, lower mold core, upper mold core, demoulding oil jar, push rod, the undershoot headstock, the center of described lower mold core and the center of upper mold core all have through hole, the central through hole of described lower mold core and the central through hole of upper mold core form die cavity, low punch is located at the below of lower mold core, the top of low punch is stretched in the die cavity, upper punch is located at the top of upper mold core, the bottom of upper punch is stretched in the die cavity, the undershoot headstock is located at the below of low punch, push rod is located at the below of undershoot headstock, be provided with piston rod in the demoulding oil jar, the top of piston rod and the bottom of push rod are connected.
Further, the outside of described lower mold core is provided with pilot sleeve.
In the extrusion process of the present invention, low punch serves as extrusion head, and the lower end of finishing blank processes.After extrusion process finished, demoulding oil jar promoted low punch the part that machines is released die cavity, pressed from both sides away by external equipment discharging manipulator, then, demoulding oil jar off-load, low punch return.When need not to push work, low punch and lower mold core are put into pilot sleeve, be beneficial to prevent that maloperation from severing low punch.
The present invention is simple in structure, and is reliable, can satisfy the requirement of production technology, can reduce manufacturing cost again, alleviates complete machine weight; Fault rate of the present invention is low, can reduce maintenance cost.
Description of drawings
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to Fig. 1, the present embodiment comprises low punch 1, die cavity 2, upper punch 3, lower mold core 5, upper mold core 6, demoulding oil jar 7, push rod 8, undershoot headstock 9, the center of the center of lower mold core 5 and upper mold core 6 all has through hole, the central through hole of the central through hole of lower mold core 5 and upper mold core 6 forms die cavity 2, low punch 1 is located at the below of lower mold core 5, the top of low punch 1 is stretched in the die cavity 2, upper punch 3 is located at the top of upper mold core 6, the bottom of upper punch 3 is stretched in the die cavity 2, undershoot headstock 9 is located at the below of low punch 1, push rod 8 is located at the below of undershoot headstock 9, is provided with piston rod in the demoulding oil jar 7, and the bottom of the top of piston rod and push rod 8 is connected.
The outside of described lower mold core 5 is provided with pilot sleeve 4, is beneficial to play guide effect.
Before the work, upper mold core and lower mold core 5 are in separated position, and the charging manipulator is sent blank in the through hole at lower mold core 5 centers to.In the extruding course of work, upper mold core 6 and lower mold core 5 closures, namely upper mold core 6 bottom surfaces contact with lower mold core 5 end faces, upper mold core 6 forms die cavity 2 with the through hole of lower mold core 5, low punch 1 forms the bottom extrusion heads with lower mold core 5, and the lower end of blank is processed, and finishes the processing to blank.After extrusion process finishes, upper mold core 6 is separated with lower mold core 5, piston rod in the demoulding oil jar 7 is boosted, drive low punch 1 by push rod 8 and undershoot headstock 9 and move upward, manufactured part is released the through hole at lower mold core 5 centers, see off by the discharging manipulator again, simultaneously, demoulding oil jar 7 off-loads, demoulding oil jar 7 inner piston rods are descending, drive low punch 1 return by push rod 8 and undershoot headstock 9; At this moment, whole device resets, enters the circulation of next part of processing.
When pushing work, low punch 1 is in lower mold core 5 and the pilot sleeve 4 always, can not only prevent that low punch from fractureing, and also is conducive to reduce the bulk of complete machine.
Use the present invention, need not during discharging by manipulator the part that machines to be pressed from both sides out from the through hole at lower mold core 5 centers; After using push rod 8 that the part that machines is ejected the through hole at lower mold core center, can it be transferred by manipulator; Low punch 1 both can be used as extrusion head, can be used as again discharging rod.
