Abstract
The invention provides a forging press plunger. The forging press plunger comprises a plunger rod, a base, a bulb and a spherical surface compression ring, wherein the base is connected with the head of the plunger rod; the bulb is arranged between the plunger rod and the base; the spherical surface compression ring is adaptive to a protrudent annular surface of the head of the plunger rod; the contact surface of the bulb and the plunger rod is spherical and is provided with a lubrication slot; and the spherical surface compression ring is matched with the protrudent annular cambered surface of the plunger rod. In the forging press plunger, the upper surface of the bulb is adaptive to the spherical surface of the plunger, so the eccentric load is effectively prevented.
Description
Technical field
The present invention relates to the forging press field, relate in particular to a kind of forging press plunger.
Background technology
Forge in the forging and pressing process, it under a lot of situations the below that the mould of needs forging and pressing is placed in the forging and pressing machine, utilize the plunger of forging press to pump, plunger comprises plunger rod part and the lower bottom base that is connected with the plunger rod head, during forging and pressing, forging press carries out forging forming by lower bottom base to the mould of below, plunger and the bulb between the lower bottom base commonly used now all are the plane bulbs, because the frequent motion of plunger rod in the forging and pressing process, the contact-making surface of lower bottom base and plunger rod all can cause bigger loss because of stressed, influences ordinary production, after loss ratio is big, plunger can produce off-centre, causes unbalance stress; In addition, when the wearing and tearing of bulb and plunger rod cause plunger rod off-centre, need to change bulb and plunger rod, waste time and energy and cost can promote greatly.Plunger rod and lower bottom base compress by the sphere pressure ring, make plunger rod and bulb from minute contacting, alleviate eccentric load, but eccentric load can't be eliminated fully, the bottom contact-making surface of existing sphere pressure ring and plunger rod all is the inclined-plane, and when having produced eccentric load, the inclined-plane can produce slip, thereby it is insufficient to cause plunger rod to contact with bulb, and plunger rod shakes.
Summary of the invention
In order to solve existing technical problem in the background technology, the present invention proposes a kind of forging press plunger, the upper surface of bulb and plunger sphere are adaptive, effectively prevent eccentric load.
Technical solution of the present invention is: a kind of forging press plunger comprises plunger rod, the base that is connected with the plunger rod head, is arranged on bulb between plunger rod and the base and the sphere pressure ring adaptive with the outstanding ring surface of plunger rod head; Its special character is: the contact-making surface of described bulb and plunger rod is a sphere; On the described contact-making surface lubrication groove is set; Described sphere pressure ring cooperates with the outstanding ring surface cambered surface of plunger rod.
The contact-making surface of above-mentioned plunger rod and bulb is the concave spherical surface adaptive with spherical shape.
The contact-making surface of above-mentioned bulb and base is the plane, and described bulb is fixedlyed connected with base.
The contact-making surface of the outstanding ring surface of above-mentioned sphere pressure ring and plunger rod is a cancave cambered surface, and the outstanding ring surface of described plunger rod is adaptive with it convex globoidal.
Above-mentioned lubrication groove is to be concentrically ringed annular lubrication groove with the bulb surface.
Above-mentioned lubrication groove is one or more.
The annular edge of above-mentioned sphere pressure ring is provided with locating ring.
Above-mentioned bulb is that bolt is connected or pin connects with the fixed form of base.
Above-mentioned locating ring is connected with the sphere junk ring bolt or pin connects.
The advantage of forging press plunger of the present invention is:
1) by bulb and the adaptive version of concave spherical surface between plunger rod and forging and pressing base, makes plunger rod off-centre can not take place, guaranteed the quality of forging and pressing.
2) upper surface at bulb is provided with a plurality of lubrication grooves, and the frictional force between bulb and the plunger is reduced, and the wearing and tearing of bulb and plunger all improve significantly.
3) by the pressure ring of cancave cambered surface annular, suitable with plunger rod, the adaptive mode of cambered surface can make plunger rod and bulb full contact, and when contact point was stressed, the difficult skew can not produce rocking of plunger rod, Stability Analysis of Structures.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the specific embodiment schematic diagram of bulb among the present invention;
The specific embodiment
Referring to Fig. 1, forging press plunger of the present invention comprises plunger rod 1, base 2, bulb 3, sphere pressure ring 4, bolt 5, locating ring 6; Bulb 3 is arranged on the base 2, and is fixed together with base 2, and connected mode can be the mode that is connected arbitrarily, for example bolt connection, pin connection etc.; Plunger rod 1 also changes concave spherical surface into accordingly with the contact-making surface of bulb 3, this frame mode, in the forging and pressing process, when 2 pairs of objects of plunger rod 1 motion drive base forge and press, when base 2 is subjected to impulse force, corresponding plunger rod 1 also can be subjected to reaction force, even plunger rod 1 that sphere is adaptive and base 2 are when being subjected to bigger power, also can prevent eccentric load, under long-term effect, wearing and tearing between the two also can reduce by the structure that sphere cooperates, and make plunger rod 1 more difficult generation skew, influence forging and pressing quality.
Referring to Fig. 2, bulb 3 with the contact surface of plunger rod 1 on have and be the circular lubrication groove 8 that concentric circles is provided with, can fill certain lubricant and reduce wearing and tearing between plunger rod 1 and the bulb 3, bulb 3 among Fig. 1 of the present invention is that upper surface is the bulb of protruding sphere, the surface is that the bulb on plane can be offered circular lubrication groove 8 too, the shape of lubrication groove 8 also can adopt other form, linear or shaped form lubrication groove horizontal or that vertically be provided with also can be realized goal of the invention of the present invention, when lubrication groove 8 is linear or shaped form, be the sealing of an end opening one end, guarantee that lubricant can be in lubrication groove.
