Description

A kind of the base forging integration mold and its forging method of bearing (ball) cover
Technical field
The invention belongs to forging mold technical fields, are concretely related to a kind of base forging integration mold of bearing (ball) cover And its forging method.
Background technique
End cap is components important in engineering machinery, is connect with bearing for protecting guide wheel, is widely used in pushing away In the equipment such as native machine, excavator.Bearing (ball) cover shape is peculiar, and majority is casting, but the bearing (ball) cover cast can generate tissue It is coarse, the problems such as defect is more, reduce the mechanical performance of product;And metal can be eliminated by the bearing (ball) cover of forging and smelted The defects of as cast condition generated in journey is loose optimizes heterogeneous microstructure, simultaneously because saving complete metal streamline, therefore forges The mechanical performance of part is generally preferred over the casting of same material, and high, operating condition sternness weight is loaded in especially suitable associated mechanical Part is wanted, so the market demand of forging end cap greatly increases, and the bearing (ball) cover mold good there are currently no practical performance.
Summary of the invention
A kind of base for the bearing (ball) cover that it is an object of the invention to provide practical performances is good, manufacture efficiency is high forges one Mold.
To achieve the above object, the technical scheme adopted by the invention is as follows:
A kind of base forging integration mold of bearing (ball) cover, it is characterised in that: including upper forging die, anvil tool and be arranged in the two Between forging thorax, the forging thorax includes the type chamber being adapted with bearing (ball) cover, the edge setting of the type chamber by overlap bridge mouth and Base die cavity is arranged in the side of the flash gutters that overlap storehouse is constituted, the forging thorax.
Constitute a kind of additional technical feature of the base forging integration mold of above-mentioned bearing (ball) cover further include:
--- the base die cavity includes cylindrical cavity and undergauge arc cavity, and the cylindrical cavity is by being located at the upper forging Semicolumn cavity in mould and anvil tool, which merges, to be constituted;The undergauge arc cavity is by being located at the upper forging die and anvil tool Interior shaft section halfbody undergauge arc cavity, which merges, to be constituted;
--- latching device is set between the upper forging die and anvil tool, and the latching device includes being arranged in the anvil tool one The first lock slots, the second lock slots are arranged in first clamping block, second clamping block at side both ends, the upper forging die corresponding position;Institute State the third clamping block of setting strip in the middle part of the other side of anvil tool, the third lock of the corresponding position setting strip of the upper forging die Determine slot;
--- the strip convex block that section is swallow-tail form is respectively set in the upper surface of the upper forging die and the lower surface of anvil tool, described Keyway is assembled in the middle part setting of strip convex block, assembles and fixes with forging equipment after plugging in fitting key;
--- the forging thorax is the type chamber that two bearing (ball) covers are arranged symmetrically, the forging of the base die cavity and the forging thorax type chamber Volume is adapted;
--- it is respectively arranged to control the first hole for hoist of its vertical lifting, institute at left and right sides of the upper forging die and anvil tool The front and rear sides for stating forging die and anvil tool are respectively arranged to control the second hole for hoist that its front and back is overturn.
A kind of base forging integration mold of bearing (ball) cover provided by the present invention compared with the existing technology, has following excellent Point: first, since the forging thorax between the upper forging die of base forging integration mold, anvil tool has the type cooperated with bearing (ball) cover Chamber forges the side setting base die cavity of thorax, realizes base, forging one operation, improves processing efficiency;Second, due to forging The flash gutters being made of overlap bridge mouth and overlap storehouse are arranged in the edge of thorax, and flash gutters can be set in upper forging die, overlap bridge mouth The resistance flowed out from impression to increase metal promotes metal full of impression, while overlap storehouse is for accommodating excess metal shape At overlap, while certain gap is arranged in overlap bridge mouth, can buffer the active force of upper and lower module, avoids its rigid impact, It prevents die joint from collapsing or bursting apart too early, extends the service life of mold;Third, since forging thorax is two symmetrical cloth of bearing (ball) cover The forging volume of the type chamber set, base die cavity and forging thorax type chamber is adapted, and forging molding a pair of bearings end cap further mentions High manufacture efficiency, while ensure that product quality is consistent, install and use effect stability.
The method that integration mold forges bearing (ball) cover is forged using above-mentioned base the present invention also provides a kind of, including following Step:
Blank size needed for being first depending on forging thorax carries out sawing to the round steel that material is 40Mn2 using sawing machine;
It is heated using bar of the heating furnace to sawing, heating temperature is 1100-1200 DEG C;
The bar heated is put into forging thorax, carries out base and forging and stamping using 10T die hammer;
Excision overlap is carried out to forging using 1250T hydraulic press;
Shot Blasting is carried out to obtained forging using shot-blasting machine.
Further include additional technical feature in above-mentioned forging method:
--- it, need to be along the operation that bar axis direction is once rotated by 90 °, front and back when heating bar is suppressed in base die cavity Base suppresses operation twice altogether, then puts the bar after the completion of base into the type chamber of forging thorax and forges.
Detailed description of the invention
Fig. 1 is the perspective view that a kind of base of bearing (ball) cover of the present invention forges integration mold;
Fig. 2 is the end cap forging for forging the mold manufacture that thorax is symmetric form chamber.
Specific embodiment
