Description
Technical field
The utility model relates to a kind of valve rod, particularly relates to the special forge die of a kind of T-shaped valve rod.
Background technology
Valve rod is valve vitals, for transmission, Shang Jie executing agency or handle, below directly band movable valve plug move or rotate, to realize valve switch or regulating action.
Valve rod not still movement parts, stressed member in valve opening and closing process, and be seal.Meanwhile, it is subject to impact and the corrosion of medium, also produces with filler and rubs.Therefore, when selector valve bar material, must ensure that it has enough intensity, good impact flexibility, resistance to marring, corrosion resistance at an established temperature.Valve rod is consumable accessory, should also be noted that machining property and the heat treatment performance of material when selecting.
A kind of T-shaped valve rod, described valve rod is rhabodoid, its one end is thicker head, the left and right sides of head offers dovetail groove, the other end of rhabodoid is threaded portion, and the central authorities of rhabodoid are polished rod portion, and the junction in head and polished rod portion is a sealing surface having chamfering, the junction of polished rod portion and threaded portion is a circular arc chamfering, and the end of threaded portion is a chamfering.
The mode of the above-mentioned T-shaped valve rod of current production has two kinds: a kind of is the method adopting casting, and it exists shortcoming and is: interior tissue is loosened, and has the defect such as shrinkage cavity, crackle, can't meet the quality requirement, there is larger potential safety hazard, and scrap more.
The method of forging can also be adopted, the patent No. is the utility model patent of CN 1986144A, a kind of valve rod forging and cold extruding formation process, comprises operations such as intercepting bar, valve stem end chamfering, valve rod slotted head, sealing surface chamfering, thread root chamfering, cold extrusion screw thread, polished rod tumbling; Its shortcoming existed is: due to valve rod shape and mould, first forge head and obtain T-shaped blank, then on milling machine, process dovetail groove, extend machining period, and materials are many, production cost is high, does not possess the market competitiveness.
Therefore be badly in need of research and development one and avoid car machining, save the special forge die of T-shaped valve rod of material.Through retrieval related documents, do not find the same or analogous technical scheme with the utility model.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and realizes basic one-shot forming, improves shaping efficiency, avoids car machining, has saved the special forge die of T-shaped valve rod of material.
For solving the problems of the technologies described above, the technical solution of the utility model is: the special forge die of a kind of T-shaped valve rod, described mould comprises cope match-plate pattern and lower bolster, its innovative point is: described cope match-plate pattern center has a upper punch, the top of upper punch is curved, both sides at right angle setting one left former locking cylinder and a right former locking cylinder respectively of described cope match-plate pattern;
Described lower bolster is provided with die holder, symmetrical left former and right former are installed in die holder, the outside of this left and right former is driven by cylinder on the right side of cylinder and on the left of respectively and moves horizontally, and the lateral surface of left and right former is one lock friction tight structure with left and right former locking cylinder piston rod; In described left and right former, correspondence is provided with symmetrical left former benevolence and right former benevolence respectively, and the top of this left and right former benevolence has the semi-circular boss of a formation dovetail groove, forms the T-shaped die chamber that holds valve rod after this left and right former benevolence matched moulds; Described die holder center is provided with undershoot, the corresponding bottom in die chamber of this undershoot; The piston rod end of described left and right former locking cylinder is tapered, and the lateral surface of described left and right former is provided with the pyramidal structure coordinated with left and right former locking cylinder piston rod.
The utility model has the advantage of:
The special forge die of valve rod of the present utility model, time shaping, after cope match-plate pattern is descending, make the piston rod of two former locking cylinders embed gap between left and right former and die holder, promote left and right former benevolence matched moulds by left and right sides cylinder, utilize the piston rod of former locking cylinder to coordinate with left and right former taper or wedge structure to promote left and right former benevolence and lock, realize the basic one-shot forming of valve rod, improve shaping efficiency, avoid car machining, save material.
Accompanying drawing explanation
Fig. 1 is the structural representation of the T-shaped valve rod that the special forge die of the T-shaped valve rod of the utility model relates to.
Fig. 2 is the structural representation of the special forge die of the T-shaped valve rod of the utility model.
Detailed description of the invention
The utility model discloses the special forge die of T-shaped valve rod, the structure of its T-shaped valve rod related to, as shown in Figure 1, valve rod is T-shaped, comprise thicker head 1, central polished rod portion 2 and threaded portion 3, the left and right sides of head 1 offers dovetail groove 4, and head 1 is an arc sealing surface 5 with the junction in polished rod portion 2; The two ends up and down of dovetail groove 4 have circular arc chamfering 6, and the end of threaded portion 3 has circular arc chamfering 7, and polished rod portion 2 and junction, threaded portion 3 have circular arc chamfering 8; The upper surface of head 1 is arc convex 9.
As shown in Figure 2, the special forge die of T-shaped valve rod, comprises cope match-plate pattern 10 and lower bolster 11, and cope match-plate pattern 10 center has a upper punch 22, and the upper end of upper punch 22 is curved, and both sides are at right angle setting one left former locking cylinder 12 and right former locking cylinder 13 respectively;
