Abstract
The utility model discloses a rotary rolling device of an integral axle head for a transportation semitrailer, which comprises a worktable, wherein a rotary rolling machine box with an axle tube installation channel is fixed on the worktable, a clamping claw capable of clamping an axle tube is arranged in the axle tube installation channel, a rotating mechanism connected with the axle tube in a driving manner is arranged on the axle tube installation channel, a roller box capable of axially sliding along the axle tube is arranged on the worktable corresponding to one end of the axle head, and at least three longitudinal rollers are arranged in the roller box along the circumferential direction of the axle tube. After the end part of the integral axle head is preheated through temperature rise, the rotary rolling device which adopts the above structure rotates at high speed after being sheathed into the rotary rolling machine box in an inserting manner, and meanwhile the roller box advances towards the rotary rolling machine box, so as to carry out rotary extrusion forming on the preheated axle head by utilizing the outer outline of the roller, thereby greatly improving the bending resistant capability of an axle.
Description
Technical field
The utility model relates to Automobile shaft and revolves rolling plant, and especially a kind of semitrailer is with the rolling device that revolves of monoblock type axletree spindle nose.
Background technology
At present, the moral formula axletree of semitrailer axletree manufacturer production both at home and abroad all adopts the three-member type manufacturing, and promptly intermediate shaft tube utilizes square tube body or welding fabrication, then the two ends spindle nose is pressed into the square tube body from two ends and welds.The axletree process procedure that adopts aforesaid way to make is many, and there are weld defect inevitably in processing time consuming, and spindle nose and square tube body employing welding and produce welding stress, have a strong impact on the firm fatigue strength of axletree.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and the revolve rolling device of a kind of semitrailer with monoblock type axletree spindle nose is provided, and it is one-body molded that central siphon and spindle nose are realized, strengthens the axletree bending resistance.
The purpose of this utility model is achieved in that
A kind of semitrailer is with the rolling device that revolves of monoblock type axletree spindle nose, comprise workbench, be fixed with the tape spool pipe on the workbench Rotary rolling mill case of passage is installed, central siphon is installed in the passage and is provided with the clamping claw that can clamp central siphon, its design feature is: described central siphon installation passage is provided with central siphon and drives the rotating mechanism that connects, the workbench of the first end of respective shaft is provided with and can be provided with at least 3 vertical running rollers by the central siphon circumferencial direction in the running roller case along central siphon running roller case in axial sliding.Adopt the rolling device that revolves of this structure, heat after the preheating in the spindle nose end, sleeve is gone into the Rotary rolling mill case and clamped back rotation at a high speed, and the running roller case advances toward Rotary rolling mill case direction simultaneously, utilize the roller outline that the spindle nose of preheating is rotated extrusion modling, strengthen the axletree bending resistance greatly.
The purpose of this utility model can also adopt following technical measures to solve:
Described should the running roller case workbench of below be provided with guide rail, workbench is seated on the guide rail by slide block, the running roller case other end and hydraulic cylinder drive and connect, before axletree revolves and rolls, rolled the position and be heated to uniform temperature revolving, in the Rotary rolling mill case,, promote the running roller case by hydraulic cylinder and advance, pass through flow forming by the rotation at a high speed of chucking back.
Revolving that the described running roller that is circle distribution surrounds rolls into the approximate taper of die cavity.
The shaped design of described running roller is according to the structure setting of axletree, and on the running roller case at running roller two ends bearing is installed, and makes running roller free to rotate.
The beneficial effects of the utility model are:
(1), its manufacturing process advantages of simple, production efficiency improves.
(2), the axletree that adopts this mechanism to make owing to adopt integral body to revolve the type of rolling into, do not have face of weld, the bulk shape smoothness, smooth.
(3), the axletree that adopts this mechanism to make owing to be that hollow steel pipe revolves the type of rolling into, compared with the three-member type that adopts solid spindle nose welding, this body weight of axletree alleviates greatly, also is the needs in market.
(4), the axletree that adopts this mechanism to make, taken into full account the stressed distribution of axletree actual working state, design the architectural characteristic at each position according to stressing conditions everywhere, make axletree bulk strength, rigidity can satisfy the serviceability requirement.
(5), integral body revolves the type of rolling into, the fiber draw of metal has continuity and is not destroyed, and strengthens the axletree bending resistance.
(6), the axletree that adopts this mechanism to make, roll in the heat treatment process of position being revolved, modifier treatment can be carried out in inside, has strengthened the anti-fatigue ability of axletree greatly.
(7), change the colleague and adopt three-member type (the two ends spindle nose separates with middle axis body) welded structure and technology manufacturing, avoided welding the defective that produced to the influence of axletree body and the generation of welding stress.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of semitrailer is with the rolling device that revolves of monoblock type axletree spindle nose, comprise workbench 1, be fixed with the tape spool pipe on the workbench 1 the Rotary rolling mill case 3 of passage 2 is installed, central siphon is installed in the passage 2 and is provided with the clamping claw 5 that can clamp central siphon 4, described central siphon installation passage 2 is provided with central siphon 4 and drives the rotating mechanism 6 that connects, the workbench 1 of corresponding spindle nose 7 one ends is provided with can be along central siphon 4 running roller case 8 in axial sliding, be provided with at least 3 rotating vertical running rollers 9 by central siphon 4 circumferencial directions in the running roller case 8, described workbench 1 that should running roller case 8 belows is provided with guide rail 10, workbench 1 is seated on the guide rail 10 by slide block 11, running roller case 8 other ends and hydraulic cylinder 12 drive and connect, revolving that the described running roller 9 that is circle distribution surrounds rolls into die cavity 13 approximate tapers, and on the running roller case 8 at running roller 9 two ends bearing 14 is installed, makes running roller 9 free to rotate.
