Abstract
Provided is an anvil for forge-pressing a cone-shaped barrel, the upper end face of the anvil (1) is in a concave shape, and a chamfer section, a facet section, an inclined plane section, a big plane section and an arc section are connected and arranged on the lower end face of the anvil (1) sequentially from left to right in a smooth transition mode. The facet section and the big plane section of the anvil are forge-pressing faces and not in a same horizontal plane. Width of the forge-pressing faces of the facet section and width of forge-pressing faces of the big plane section are different, the facet section and the big plane section are connected by the inclined plane section which transits smoothly and also is a forge-pressing face. During forge-pressing, metal flow flows mainly towards the tangential direction of the cone-shaped barrel and flows less in the width direction. Therefore, copy forge-pressing of hollow cylindrical barrels on two ends of the cone-shaped barrel and with different diameters is guaranteed; and when chamfer happens at end face edges of the facet section, the inclined plane section and the big plane section, folding of the cone-shaped barrel during forge-pressing is avoided. The cone-shaped barrel can be directly copy forge-pressed by exerting forge-pressing force on the anvil, therefore technical requirements are met, forge-pressing property of the cone-shaped barrel is improved, and simultaneously cost is greatly reduced.
Description
Technical field
The utility model belongs to the forging tools technical field, especially a kind ofly forges and presses the hammering block that conical shell is used.
Background technology
At present, on water (oil) press workpiece forged and pressed and add man-hour, adopt flat anvil and V-type hammering block etc. mostly, these a few class hammering blocks are difficult to finish the cylinder straight section part at conical shell, especially the conical shell two ends of complexity of Forging Technology.
Conical shell generally constitutes by three sections, its two ends are the unequal hollow cylinders of diameter, middle is transition hollow cone section, because three sections of conical shell on a horizontal level, obviously flat anvil and V-type hammering block are the forging processing that can not be used for conical shell, and this just need make and forge the special-purpose hammering block that conical shell is used.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of hammering block that conical shell is used that forges and presses, the forging and pressing contact-making surface of this hammering block and the outer surface of conical shell coupling, wherein two planar sections of hammering block are not on the same horizontal plane, the width of two planar sections is also inequality, material amount of flow difference when therefore forging and pressing conical shell, the reaming demand at different-diameter place when having realized the conical shell forging and pressing.
For achieving the above object, the utility model adopts following technical scheme:
A kind ofly forge and press the hammering block that conical shell is used, the upper surface of this hammering block is spill, the from left to right natural transition in its lower surface is connected with the chamfering section, the facet section, bevel phase, big planar section and arc section, the gradient of described bevel phase equates with the tapering of shaping conical shell, described bevel phase is along the vertical length of hammering block length direction equal the to be shaped vertical length of conical shell cone segments, described facet section is along the length of the hammering block length direction length greater than the big hollow cylinder of shaping conical shell, described big planar section is along the length of the hammering block length direction length greater than the little hollow cylinder of shaping conical shell, the width of described facet section is less than the width of described big planar section, the width of described big planar section is approximately equal to the width of hammering block, described facet section and described big planar section since the natural transition of described bevel phase connect and be not on the same horizontal plane.
End face edge place at described facet section, bevel phase, big planar section carries out chamfering.
Owing to adopt technical scheme as mentioned above, the utlity model has following good effect:
1, the utility model is at forging and pressing conical shell or reaming and contoured design, and the difficult shaping problem of forging and pressing of the bearing that solved the conical shell two ends because diameter is unequal has improved the forming effect of conical shell, provides cost savings.
2, the end face edge place of facet section, bevel phase, big planar section carries out chamfering and can avoid that folding phenomenon appears in conical shell in the forging and pressing process.
3, because the width of facet section and big planar section is unequal, thus the material amount of flow difference of conical shell in the forging and pressing process, the reaming demand at different-diameter place when having realized the conical shell forging and pressing.
Description of drawings
Fig. 1 is the structural representation of the utility model hammering block.
Fig. 2 is that the utility model is specifically used schematic diagram.
Among Fig. 1: the 1-hammering block.
The specific embodiment
In conjunction with Fig. 1, the upper surface of the utility model hammering block 1 is spill, the from left to right natural transition in its lower surface is connected with the chamfering section, the facet section, bevel phase, big planar section and arc section, the gradient of described bevel phase equates with the tapering of shaping conical shell, described bevel phase is along the vertical length of hammering block length direction equal the to be shaped vertical length of conical shell cone segments, described facet section is along the length of the hammering block length direction length greater than the big hollow cylinder of shaping conical shell, described big planar section is along the length of the hammering block length direction length greater than the little hollow cylinder of shaping conical shell, the width of described facet section is less than the width of described big planar section, the width of described big planar section is approximately equal to the width of hammering block, described facet section and described big planar section since the natural transition of described bevel phase connect and be not on the same horizontal plane.
The facet section of hammering block and big planar section are not at the forging and pressing face of same horizontal plane, and the forging and pressing face width degree of facet section and big planar section has nothing in common with each other, connecting the facet section is the bevel phase of nature transition with big planar section, this bevel phase also is a forging and pressing face, the metal flow momentum mainly is to flow along the tangential of conical shell during forging and pressing, and it is very little at width metal flow momentum, guaranteed the profiling forging of the unequal hollow cylinder of conical shell two ends diameter, and the facet section, bevel phase, the end face edge place of big planar section carries out the folding phenomenon that chamfering can effectively prevent conical shell in the forging and pressing process.By hammering block is applied forging force directly profiling forge and press out the shaping conical shell, satisfy specification requirement, improved the forging and pressing performance of conical shell, also greatly reduce simultaneously cost.
In conjunction with Fig. 2, when profiling is forged and pressed, the plug insertion is had in the round blank of tapering, then plug is placed on the plug reaming with on the saddle support, base and and each arc groove seat between add pad and regulate about the height of end saddle support, the rotating speeds of realizing the different ends of conical shell reach the speed that needs, and circle blank external diameter are exerted pressure and the continuous rotation of plug realizes the profiling forging and pressing of conical shell by hammering block.
