Abstract
The utility model discloses die pressing equipment for processing a valve seat of a butterfly valve, which comprises a rack, wherein an upper die and a lower die which are mutually matched are installed on the rack, and both sides of the lower die are provided with a technological rod corresponding to the position of a hole of a valve rod of the lower die and a driving mechanism for driving the technological rod to expand and contract. In the die pressing equipment for processing the valve seat of the butterfly valve, which is disclosed by the utility model, the technological rod can be automatically expanded and contracted by the driving of the driving mechanism and is inserted into or pulled out of the hole of the valve rod of the lower die.
Description
Technical field
The utility model relates to the process equipment of butterfly valve seat, relates in particular to a kind of molding apparatus that is used to process butterfly valve seat.
Background technology
In the valve body of butterfly valve, be provided with and be used for the valve seat that is sealed and matched with valve plate, general valve seat is a ring structure, by bracing ring and the rubber layer that partly wraps up bracing ring constitute, valve seat also is provided with the through hole that is used to pass valve rod.
Utilize molding apparatus during bracing ring parcel rubber layer; Bracing ring and rubber mass are inserted in the counterdie, and then patrix is descending directly compresses and heats with counterdie, and wherein the sidewall of counterdie has and the corresponding valve rod hole in valve seat through-hole position; In hot-forming process; Need artificial insertion process bar in the valve rod hole of counterdie, avoid rubber to flow into, extract the technology bar out after hot pressing is accomplished and mention patrix again.
The plug of manually-operated technology bar in the prior art, labour intensity is bigger, and efficient is low, has prolonged process time.
The utility model content
The utility model provides a kind of molding apparatus that is used to process butterfly valve seat that can control the plug of technology bar automatically.
A kind of molding apparatus that is used to process butterfly valve seat comprises frame, and the upper die and lower die that cooperatively interact are installed on the frame, and the both sides of described counterdie are provided with the corresponding technology bar in the valve rod hole position of counterdie and are used to drive the flexible driving mechanism of technology bar.
Described driving mechanism is hydraulic cylinder or cylinder.
Be fixed with bearing on the described frame, described driving mechanism is fixed on the corresponding bearing.
The both sides of described counterdie are provided with guide rail, and described patrix and guide rail are slidingly matched.
For driving patrix, be provided with the patrix driving mechanism at the top of described frame.The patrix driving mechanism is for providing the hydraulic cylinder of big pressure.
The utility model is used to process the molding apparatus of butterfly valve seat, and driving the technology bar through driving mechanism can stretch automatically, inserts or extract the valve rod hole of counterdie.
Description of drawings
Fig. 1 is used to process the structural representation of the molding apparatus of butterfly valve seat for the utility model is a kind of;
Fig. 2 is in the structural representation of user mode for the molding apparatus among Fig. 1.
The specific embodiment
Referring to accompanying drawing, a kind of molding apparatus that is used to process butterfly valve seat of the utility model comprises frame 1, and the patrix 5 and counterdie 6 that cooperatively interact are installed on the frame 1.
Be provided with guide rail 4, patrix 5 is installed on the sliding seat 2, and this sliding seat 2 is slidingly matched with guide rail 4, makes patrix 5 counterdie 6 motions relatively.
For driving patrix 5, be provided with patrix driving mechanism 3 at the top of frame 1.Patrix driving mechanism 3 is for providing the hydraulic cylinder of big pressure.
The both sides of counterdie 6 are provided with the corresponding technology bar 7 in the valve rod hole position of counterdie 6 and are used to drive the driving mechanism 8 that technology bar 7 stretches.
Driving mechanism 8 is a cylinder, is fixed on the frame 1 through bearing 9.
The molding apparatus that the utility model is used to process butterfly valve seat in use; Bracing ring is inserted in the counterdie; Drive the valve rod hole that the technology bar inserts counterdie through driving mechanism, in counterdie, add rubber mass again, patrix is descending to be compressed with counterdie; Have electric heating element in the upper die and lower die, heating is flowed attached to the bracing ring outside it to rubber mass.Drive the valve rod hole that the technology bar is extracted counterdie through driving mechanism before the die sinking, mention patrix again, accomplish the hot-forming of valve seat.
