Abstract
The invention relates to a fixture for a ring forging with an outer step having an L-shaped cross section. The fixture comprises a cover die, an upper punch, a lower punch and a main die. The cover die is a cylinder with a big-end-down cone frustum hole in the middle, and the lower edge of the cone frustum hole is provided with a fillet. An inverted truncated cone section and a cylinder section are coaxially arranged on the upper punch sequentially from top to bottom to form a whole, and the small diameter of the inverted truncated cone section is equal to the diameter of the cylinder section. The lower punch is provided with a truncated cone, and the diameter of the cylinder section of the upper punch is not smaller than the small diameter of the truncated cone of the lower punch. A cylinder with an L-shaped groove is arranged in the outer wall of the main die, the size of the L-shaped groove corresponds to that of the L-shaped step of the ring forging needing to be forged, and a stopper is arranged at the upper end of the L-shaped groove. The fixture is applicable to forging of the ring forging with the outer step having the L-shaped cross section, materials and energy are saved, and stable rolling, precise size and complete filling can be realized.
Description
Technical field
The present invention relates to the production technical field of section of outer step forging special-shape ring, relate in particular to the L shaped ring forgeable piece tool of a kind of section of outer step.Be mainly used in the forging of the L shaped ring rolling spare of section of outer step, belong to the forging special-shape ring technical field of mold.
Background technology
The application at home and abroad of the L shaped ring rolling spare of section of outer step is very extensive, especially aspect engineering machinery, wide prospect is arranged, and is the important component part of mine mechanism.The structure of the L shaped ring rolling spare of section of outer step is as shown in Figure 6, and expect less by top in order to appear up and down for its outer wall, the many L shaped steps 61 of bottom material.When forging and pressing; At first adopting structure is that the cover mould of centrum hollow forges and presses; Adopting structure then is that the low punch of cone descends punching; Adopting structure afterwards is thereby that the upper punch of butt cylinder is gone up punching and made the blank material, adopts the capable groove master of the L mould of band block to roll over ring at last, makes ring rolling spare.Traditional outer L shaped ring rolling spare Forging Technology fails to realize the distribution of outer step loading and unloading when base, rolling over when ring, rolled piece can occur radially with axial metal distribute uneven, rolling not steadily, fill the incomplete phenomenon of type; And traditional main mould is when rolling over ring, and the easy vibration deformation of rolled piece, dimensional discrepancy are big.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of blank material that can make the time can directly realize outer step loading and unloading distribution in compacting; When rolling over ring, reduce the L shaped ring forgeable piece tool of section of outer step of bandaging piece vibration deformation, and can make rolling steadily, size accurately, to fill type complete.
For addressing the above problem, the technical scheme that the present invention adopts is: the L shaped ring forgeable piece tool of section of outer step, comprise cover mould, upper punch, low punch and main mould, and said cover mould is the cylinder that the middle part is provided with up-small and down-big round platform hole, the lower edge rounding in round platform hole; Described upper punch constitutes an integral body by falling frustoconical section with coaxial setting of shell portion from top to bottom successively, and the minor diameter of frustoconical section equals the diameter of shell portion; Described low punch is a truncated cone; The diameter of the shell portion of described upper punch is not less than the minor diameter of the truncated cone of low punch; Described main mould is the cylinder that is provided with L shaped groove in the outer wall, and the size of L shaped groove is corresponding with the size of the L shaped step of required forging ring rolling spare, and the upper end of L shaped groove is provided with block.
The diameter of the shell portion of described upper punch equals the minor diameter of the truncated cone of low punch.
The invention has the beneficial effects as follows: adopt the above-mentioned L shaped ring forgeable piece tool of section of outer step; Can make the direct distribution that realizes interior step loading and unloading in the base process, when adopting main mould to roll over ring, the rolled piece ability is rolling steadily, size is accurate, it is complete to fill type; And then reduced the scrappage of ring rolling spare; Practice thrift material, saved the energy and man-hour, improved production efficiency.

The specific embodiment
Through specific embodiment the L shaped ring forgeable piece tool of section of outer step of the present invention is done further to describe in detail below.
The L shaped ring forgeable piece tool of section of outer step comprises cover mould 1, upper punch 3, low punch 2 and main mould 4, and is as shown in Figure 1, the cylinder in the round platform hole 11 that said cover mould 1 is up-small and down-big for the middle part is provided with, the lower edge rounding 12 in round platform hole 11; As shown in Figure 3, described upper punch 3 constitutes an integral body by falling frustoconical section 31 with shell portion 32 coaxial settings from top to bottom successively, and the minor diameter of frustoconical section 31 of falling equals the diameter of shell portion 32; As shown in Figure 2, described low punch 2 is a truncated cone; The diameter of the shell portion 32 of described upper punch 3 is not less than the minor diameter of the truncated cone of low punch 2, and the minor diameter that wherein equals the truncated cone of low punch with the diameter of the shell portion 32 of upper punch 3 is the best; As shown in Figure 4, described main mould 4 is for being provided with the cylinder of L shaped groove 42 in the outer wall, and the size of L shaped groove 42 is corresponding with the size of the L shaped step 61 of required forging ring rolling spare 6, and the upper end of L shaped groove 42 is provided with block 41.
Operation principle of the present invention is: when forging and pressing; At first adopt 1 pair of blank of cover mould to suppress, adopt 2 times punchings of low punch then, adopt upper punch 3 to go up punching afterwards; Thereby make structure blank material 5 as shown in Figure 5; Ring is rolled in the outside of adopting main mould 4 to be pressed on blank material 5 at last, and the L shaped groove 42 through main mould 4 outer walls makes L shaped step 61, finally makes structure ring rolling spare as shown in Figure 66.Wherein, at first blank material 5 to be pressed into top be that little truncated cone, bottom are big butt cylinder to cover mould 1, makes outer step loading and unloading reasonable distribution to occur in the blank material 5; When upper punch 3 carries out punching, again because the diameter of the little butt shell portion of upper punch 3 equals the minor diameter of the cone of low punch 2, under the momentum effect of low punch 3; Make blank material 5 realize that punching and blanking makes centre bore 51, when adopting main mould 4 to roll over ring, because the restriction of block 41; Make that the rolled piece ability is rolling steadily, size is accurate, it is complete to fill type, and then reduced the scrappage of ring rolling spare 6, practiced thrift material; Save the energy and man-hour, improved operating efficiency.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
