Description

Bearing forging is with grinding expansion machine
Technical field
The utility model relates to a kind of bearing forging and grinds expansion machine.
Background technology
At present, bearing ring in process of production, need to use stone roller expansion machine to process, although conventional stone roller expansion machine structure is simple, but use trouble, the front support that common stone roller expands machine adopts the move mode of hinged rotation to support forging, in switching process, when the scale error that plug is processed due to front road, the center of the forging of shape is had to require or the factor such as to coordinate of tapered sleeve of plug and lower support all can affect due to assembly precision, after as long as plug position occurs that front support upset is now got on by deviation etc., between the two because matching relationship occurs small flexural loading by making plug, such as when core roller position compared to design attitude reach or after move time, the air line distance of moving before and after this little and before the pin joint of front support will be greater than original designed distance (namely original designed distance is the air line distance between design attitude and front support pin joint), when by after on front support returning buckle, downward pressure must be caused to core roller, to change in length below 200 plug linearity and in stress, in hot-working, often plug is easy to fracture like this, also do not consider the quality in kind of product, therefore the stone roller of conventional structure expands machine needs often to change its core roller, owing to being hot-working, because plug breaks, one can not stop heating, two increase the weight of the time of changing plug of employee and muscle power again, so from energy consumption, labour intensity causes waste all virtually, also do not consider also to have increased the weight of the manufacture maintenance cost of its sliver because plug breaks, the batch of this this bearing forging is just high to quality requirement, and just because this procedure just may Ka Guan, and the machining requirements of this kind of hinged upset mode to employee is high, and inefficiency, has very large restriction to large-scale mass production.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of quality of production high and the later stage manufactures the cheap bearing forging stone roller expansion machine of maintenance cost.
The purpose of this utility model is achieved in that
A kind of bearing forging is with grinding expansion machine, described stone roller expansion machine includes the milling roller be installed on support, described support is provided with core roller and at least two armfuls of rollers, described core roller and an armful roller are positioned at below milling roller, one ring base is placed between milling roller and core roller, and ring base and an armful roller phase close contact, described support slides and is provided with a front support, and front support parallels setting with ring base.
A kind of bearing forging of the utility model is with grinding expansion machine, slide block is provided with bottom described front support, technical staff according to the highly disposable equipment adjustment of assembling of lower support and plug height well, owing to support being provided with the slide rail embedding slide block, making can not as original radial type overturn structure, before and after move a little and front support pin joint before air line distance will be greater than original designed distance (namely original designed distance is the air line distance between design attitude and front support pin joint), when by after on front support returning buckle, downward pressure must be caused to core roller, no matter movable how many positions of such maintenance front support, consistent relative to the center height of plug, a cylinder is provided with again in front support, the cylinder block of this cylinder is fixed on support, the piston rod of cylinder is connected with front support.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is provided support by the front support be slidably connected paralleling setting with ring base, thus make better to the support effect of ring base, processing effect is better; When operating personnel operate, switching cylinder is only needed to make front support carry out slippage, without the need to as traditional articulated manner, also need to rotate laggard pedestrian for debugging to it, thus damage can not be caused to core roller, the use reducing the later stage manufactures maintenance cost, contributes to improving its production efficiency and the quality of production; The utility model stone roller expansion machine structure is simple, easy to use, easy to utilize; And because plug is continuous, the raising of production efficiency, makes energy consumption etc. all significantly reduce.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of bearing forging of the utility model grinds expansion machine.
Fig. 2 is the side view that a kind of bearing forging of the utility model grinds Fig. 1 of expansion machine.
Wherein:
Milling roller 1, core roller 2, armful roller 3, ring base 4, front support 5, support 6.
Detailed description of the invention
See Fig. 1 and Fig. 2, a kind of bearing forging that the utility model relates to grinds expansion machine, described stone roller expansion machine includes the milling roller 1 be installed on support 6, described support 6 is provided with core roller 2 and at least two armfuls of rollers 3, described core roller 2 and an armful roller 3 are positioned at below milling roller 1, and a ring base 4 is placed between milling roller 1 and core roller 2, and ring base 4 and an armful roller 3 phase close contact, described support 6 slides and is provided with a front support 5, and front support 5 parallels setting with ring base 4; Concretely, slide block is provided with bottom described front support 5, described support 6 is provided with the slide rail embedding above-mentioned slide block, thus make front support 5 can slippage on the frame 6, described support 6 is provided with a cylinder, the cylinder block of this cylinder is fixed on support 6, and the piston rod of cylinder is connected with front support 5, thus promotes front support 5 slippage;
During work, ring base 4 is set on core roller 2, adjustment milling roller 1 and armful roller 3, make its all with ring base 4 phase close contact, slip front support 5, makes it provide support the ring base 4 as forging, because ring base 4 and front support 5 are parallel to each other, thus it is well stable to ensure that it supports, and contributes to anti-stop ring base 4 and cause defect ware because of reasons such as shakes in process.
In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
