Abstract
The utility model discloses an improved train wheel forming die with an ejector structure. The improved train wheel forming die with the ejector structure comprises a die and the ejector structure arranged on the die, wherein the ejector structure comprises an ejector ring (7) and an ejector rod (8); the die comprises an upper die (1), a lower die (2) and an annular die (3); a circular upper boss (4) is arranged on the lower surface of the upper die (1); a groove is arranged at the center of the lower surface of the upper die (1); a supporting column (5) is arranged at the center of the lower die (2); and a circular lower boss (6) taking the supporting column (5) as a center is further arranged on the lower die (2). As the improved train wheel forming die adopts the ejector structure, a rim is prevented from deforming and upwarping, and a hub is prevented from being ejecting out of a pit.. Meanwhile, a correction process further can be eliminated, so that the production efficiency can be improved.
Description
Technical field
The utility model relates to train wheel manufacturing, manufacture field, specifically is the modified train wheel shaping dies that has ejecting structure.
Background technology
Roll in the document of producing wheel at existing relevant pendulum, do not have special argumentation for the wheel form of ejecting, according to the accompanying drawing and the introduction of its article of delivering, can draw is at wheel hub and wheel rim two places the mode that push rod ejects to be set.But in practice, but have some problems, such as when ejecting, the wheel rim place is prone to the demoulding; The ejecting force that needs is less, and wheel bore is owing to exist with the mould support column power of holding tightly, and the ejecting force that needs is very big; In the process that workpiece ejects, owing to wheel rim is up walked earlier, and wheel hub is moving; Cause wheel rim to upwarp and be out of shape, and push rod ejects the hole that the degree of depth surpasses 6mm in wheel hub, cause wheel hub allowance deficiency possibly cause part to scrap and increase the operation of school shape.
The utility model content
The utility model provides a kind of modified train wheel shaping dies that has ejecting structure; Having solved wheel shaping dies in the past causes wheel rim to upwarp and distortion and wheel hub allowance deficiency possibly cause part to scrap easily; Also increase school shape operation simultaneously, influence the problem of production efficiency.
The utility model is that the technical solution problem mainly realizes through following technical scheme: have the modified train wheel shaping dies of ejecting structure, comprise mould and be arranged on the ejecting structure on the mould, said ejecting structure comprises apical ring and push rod; Said mould comprises upper die and lower die and ring mould, and counterdie is positioned at the ring mould, and the lower surface of said patrix is provided with circular convex platform; Said convex platform is the center of circle with the center of the lower surface of patrix; The center of the lower surface of said patrix is provided with a groove, and the center of said counterdie is provided with a support column, and also being provided with on the said counterdie with the support column is the circular lower convex platform at center; Counterdie between said lower convex platform and the support column is provided with cannelure; The bottom of said cannelure is provided with the through hole that runs through counterdie, and said push rod is arranged in the through hole, and apical ring is arranged in the cannelure.
Said lower convex platform is provided with cannelure, and the bottom of said cannelure is provided with the through hole that runs through counterdie, is provided with push rod in the said through hole, is provided with apical ring in the cannelure.
The cross section of said groove and support column be shaped as circle, the area of bottom portion of groove is equal to or greater than the area at support column top.
Being shaped as of the longitudinal section of said groove and support column is trapezoidal.
The equal diameters of said convex platform and lower convex platform, and convex platform and lower convex platform are positioned on the same vertical straight line.
The angle of the center line of said patrix and the center line of counterdie is 1.5 °.
The utility model compared with prior art has the following advantages and beneficial effect: the utility model is provided with cannelure on counterdie, and in cannelure, puts into an apical ring respectively, after the workpiece pendulum is rolled over and is shaped; In the process of ejecting; Ejecting force passes to apical ring through push rod, and apical ring is ejected mold cavity with workpiece, has solved so effectively at pendulum to roll in the production process; Because of being provided with the improper rim deformation that causes, the liftout mode upwarps the problem that is ejected pit with wheel hub; Also reduce school shape operation simultaneously, improved productivity ratio, reduced cost.

Fig. 2 is the profile of the utility model.
Pairing Reference numeral is in the accompanying drawing: 1, patrix, 2, counterdie, 3, the ring mould, 4, convex platform, 5, support column, 6, lower convex platform, 7, apical ring, 8, push rod.
The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
Like Fig. 1, shown in Figure 2, the utility model comprises mould and is arranged on the ejecting structure on the mould, and ejecting structure comprises apical ring 7 and push rod 8, and mould comprises patrix 1, counterdie 2 and ring mould 3, and counterdie 2 is positioned at ring mould 3.
The lower surface of the patrix 1 of present embodiment is provided with circular convex platform 4; Convex platform 4 is the center of circle with the center of the lower surface of patrix 1; The center of the lower surface of patrix 1 is provided with a groove; The cross section of groove and support column 5 be shaped as circle, being shaped as of longitudinal section is trapezoidal, the area of bottom portion of groove is equal to or greater than the area at support column 5 tops.
The center of the counterdie 2 of present embodiment is provided with a support column 5; Also be provided with on the counterdie 2 with support column 5 is the circular lower convex platform 6 at center; Counterdie between lower convex platform and the support column is provided with cannelure; The bottom of cannelure is provided with the through hole that runs through counterdie, and push rod 8 is arranged in the through hole, and apical ring 7 is arranged in the cannelure.
The lower convex platform 6 of present embodiment is provided with cannelure, and the bottom of cannelure is provided with the through hole that runs through counterdie 2, is provided with push rod 8 in the through hole, is provided with apical ring 7 in the cannelure.
