Description

Rotary-cut, roll forging machine
Technical field:
The utility model relates to the abrading-ball production technical field, especially forge ball and produce special-purpose rotary-cut, roll forging machine.
Background technology:
In the prior art, the mode of production of abrading-ball comprises two kinds of forged steel ball and steel ball castings.Wherein the common mode of production of forged steel ball has two kinds: a kind of is to adopt pneumatic hammer to forge, and its technological process of production is: raw material forges in mould with pneumatic hammer after cutting off, heating.This kind mode of production operation link is many, and labour intensity is big, and production efficiency is low.Another kind is to adopt roll forging steel ball production line, and its technological process of production is: round steel blanking → heating furnace heating → upsetting press blocking → roll forging machine roll forging is shaped.Though the method has improved the output and the quality of steel ball to a certain extent, but blanking, blocking two procedures, it is bigger influenced by apparatus factor, moulds of industrial equipment and human factor, take place easily during blanking that size different in sizely causes, blanking inclined-plane burr is big, the influence that adjusted by mould is bigger, unstable product quality, product percent of pass is low and cause production cost of products high.
Summary of the invention:
The purpose of this utility model is exactly at the existing in prior technology deficiency, provides a kind of novel steel ball to produce special-purpose rotary-cut, roll forging machine.Not only production output of steel ball height, production cost that this device fabrication goes out are low, and have reduced working strength of workers, make production environment obtain big improvement.
This programme is realized by following technical measures: rotary-cut, roll forging machine, include frame, power set, by rack-mounted main rotary-cut roll forging roller of bearing block and secondary rotary-cut roll forging roller, it is characterized in that: between the axis of the axis of described main rotary-cut roll forging roller and described secondary rotary-cut roll forging roller an angle is arranged.
The axis angle of the axis of described main rotary-cut roll forging roller and described secondary rotary-cut roll forging roller is 10~20 °.
Described main rotary-cut roll forging roller and secondary rotary-cut roll forging roller constitute by the roll forging roller of taper rotary-cut roller and coaxial setting.
The larger diameter end of described tapered rotary-cut roller and described roll forging roller join, and are provided with coherent helical form arc groove on the outer surface of roll forging roller and tapered rotary-cut roller.
Between main rotary-cut roll forging roller and secondary rotary-cut roll forging roller, locating on the frame, be respectively arranged with upper guide plate and bottom guide.
Described frame is provided with adjustable bearing block.
Frame is provided with the horizontal adjusting device of bearing block.
Frame is provided with the longitudinal adjusting device of bearing block.
Frame is provided with the height adjuster of bearing block.
Height adjuster is made up of pallet, the wedge-shaped adjusting block that is positioned at the pallet below and adjustment screw rod.
The beneficial effect of this programme can be learnt according to the narration to such scheme, rolls owing to front end in this scheme is provided with rotary-cut, has omitted blanking, blocking two procedures, not thought by apparatus factor, moulds of industrial equipment and human factor shadow.And the heating-up temperature that the steel ball ball warp is gone through in the production process, rotary-cut time, roll forging time, molding time uniformity are gone in the heat treatment process, leaving water temperature, time uniformity, so the inside and outside hardness uniformity of steel ball, the abrading-ball quality of production is stable.
Owing between the axis of main rotary-cut roll forging roller and the axis of described secondary rotary-cut roll forging roller an angle is arranged.So the ball-type blank is subjected under the effect of spiral power in the arc groove of roll forging roller; can roll in the time of reach; improved round as a ball effect; realize the round as a ball integer of secondary; product quality and production efficiency have been improved greatly; save a large amount of steel, electric power, reduce production costs, and reduce and pollute, protect environment.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Among the figure, 1 is main rotary-cut, roll forging roller, and 2 is secondary rotary-cut, roll forging roller, 3 is round steel, and 4 is frame, and 5 is upper guide plate, 6 is bottom guide, and 7 is forward and backward adjusting device, and 8 is left and right adjusting device, 9 is upper and lower adjusting device, and 10 is bearing block, and 11 is pallet, 12 is tapered rotary-cut roller, and 13 are the roll forging roller, and 14 is roller bearing, 15 for adjusting screw rod, and 16 is wedge-shaped adjusting block.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, this programme is realized by following technical measures: rotary-cut, roll forging machine, include frame 4, power set, be installed in main rotary-cut roll forging roller 1 and secondary rotary-cut roll forging roller 2 on the frame 4 by bearing block 10, it is characterized in that: between the axis of the axis of described main rotary-cut roll forging roller 1 and described secondary rotary-cut roll forging roller 2 angle is arranged.
The axis angle of the axis of described main rotary-cut roll forging roller 1 and described secondary rotary-cut roll forging roller 2 is 20 °.
Described main rotary-cut roll forging roller 1 and secondary rotary-cut roll forging roller 2 constitute by the roll forging roller 13 of taper rotary-cut roller 12 and coaxial setting.
The larger diameter end of described tapered rotary-cut roller 12 and described roll forging roller 13 join, and are provided with coherent helical form arc groove on the outer surface of roll forging roller 13 and tapered rotary-cut roller 12.
Between main rotary-cut roll forging roller 1 and secondary rotary-cut roll forging roller 2, locating on the frame 4, be respectively arranged with upper guide plate 5 and bottom guide 6.
Described frame 4 is provided with adjustable bearing block 10.
Frame 4 is provided with the horizontal adjusting device 8 of bearing block 10.
Frame 4 is provided with the longitudinal adjusting device 7 of bearing block 10.
Frame 4 is provided with the height adjuster 9 of bearing block 10.
Height adjuster 9 is made up of pallet 11, the wedge-shaped adjusting block 16 that is positioned at pallet 11 belows and adjustment screw rod 15.
After the finished product round steel is heated to 1150 ℃~1150 ℃, round steel is transported between two rotary-cut rollers.Round steel after the heating enters between two rotary-cut rollers from the bigger end in gap, the arc groove top end face of two rotary-cut rollers rotate in the same way the rotary-cut power of generation and two arc groove top end faces to the extruding force effect of heating the back round steel under, when the drive round steel moves between two rotary-cut rollers, utilize incremental rotary-cut, extruding, little by little rotary-cut is disconnected with round steel, and forms approximate ball-type blank gradually.The ball-type blank continues reach down by the promotion that roll shaft rotates the spiral power that makes the arc groove generation, because the arc groove of rotary-cut roller is connected with the roll forging roller, so the ball-type blank continues to enter in the arc groove of two roll forging rollers.Again because the axis of two roll forging rollers intersects, so the ball-type blank is subjected under the effect of spiral power in the arc groove of roll forging roller, can roll in the time of reach, improved round as a ball effect, realize the round as a ball integer of secondary, make its any surface finish, outward appearance slyness, solved the defectives such as trailing edge burr after the rotary-cut.And, further improved the mechanical performance after the steel ball roll forging through the secondary round as a ball secondary deformation that has increased material.
