AI Technical Summary
The swing baffle is easily damaged during the billet throwing process, and existing technologies are unable to effectively prevent such damage.
A billet conveying roller conveyor was designed, including a swing baffle and a lower buffer. The swing baffle consumes the mechanical energy of the billet and partially buffers it, while the lower buffer consumes part of the mechanical energy through a support plate to reduce the impact force and prevent damage to the swing baffle and the bearings inside the roller.
It effectively reduces damage to the swing baffle and the bearings inside the rollers, extends the service life of the equipment, and improves the stability of the equipment.

TECHNICAL FIELD
[0001] The utility model belongs to the technical field of steel pipe processing, and particularly relates to a billet conveying roller. BACKGROUND
[0002] Piercing is the first process of seamless steel pipe production, which is used to pierce solid pipe blank into a pipe blank, and the pipe blank needs to be transported through a roller after being heated.
[0003] For example, Figure 1 When the billet 90 moves forward on the chain conveying table 91, it is thrown to the swing baffle 20 and then falls on the roller 21 after leaving the chain conveying table 91, and is conveyed to a downstream component through the roller 21.
[0004] The problem is that the swing baffle 20 is easily damaged after being hit multiple times as the billet 90 is continuously thrown to the swing baffle 20. TECHNICAL PROBLEM
[0005] The utility model solves the technical problem of how to design a billet conveying roller and how to prevent the swing baffle from being damaged.
[0006] The technical scheme of the utility model is as follows:
[0007] A billet conveying roller comprises a roller, the roller comprises a row of rollers, a swing baffle is fixed to the rear side of the roller, the swing baffle comprises a swing baffle and a rear swing baffle, the rear swing baffle is fixed to the ground of a work station, the swing baffle is arranged in front of the rear swing baffle, a cross beam is arranged above the swing baffle, and the upper part of the swing baffle is hingedly connected to the lower part of the cross beam.
[0008] The lower rear side of the rear swing baffle is fixed with an inclined support support plate.
[0009] A lower buffer is arranged in the gap of the roller, the lower buffer comprises a plurality of support plates, the support plates are arranged between two adjacent rollers, the front ends of all the support plates are fixed to a rotating shaft, and the rear end upper surface of the support plate is a support surface; when the support plate is in a high position, the support surface is higher than the upper roller surface of the roller; and when the support plate is in a low position, the support surface is lower than the upper roller surface of the roller.
[0010] Compared with the prior art, the utility model has the technical effect that the swing baffle is arranged, the movement of the swing baffle consumes part of the mechanical energy of the billet, at the same time, the billet is partially buffered, the impact on the rear swing baffle is weakened when the swing baffle hits the rear swing baffle, and the rear swing baffle can be prevented from being damaged.

[0018] The utility model will be described in detail below in combination with the drawings and its specific embodiment.
[0019] As Figures 2-7 , a billet conveying roller way, including the roller way 21, the roller way 21 includes a row of rollers 28, the rear side ( the opposite direction of incoming material, the right side in the figure) of the roller way 21 is fixed with swing baffle. Figure 2
[0020] As Figures 6-7 , the swing baffle includes swing baffle 20 and rear swing baffle 30, and the rear swing baffle 30 is fixed on the ground of the station, and the swing baffle 20 is arranged in front of the rear swing baffle 30, and the upper portion of the swing baffle 20 is hinged to the lower portion of the crossbeam 22.
[0021] In order to stabilize, the lower rear side of the rear swing baffle 30 is fixed with inclined support 31 support plate.
[0022] When the billet 90 falls on the roller way 21, it will also bring vibration or vibration to the roller way 21, and the roller is provided with a bearing, and the bearing is a precision component and is also a vulnerable part, because the impact force of the billet 90 on the roller way 21 is large, therefore, further improvement.
[0023] As Figures 2-5 , the gap of the roller way 21 is provided with a lower buffer, and the lower buffer includes a plurality of support plates 11, the support plates 11 are located between two adjacent rollers 28, the front ends of all the support plates 11 are fixed on the rotating shaft 10, the rear end upper surface of the support plate 11 is a support surface 12, when the support plate 11 is in the high position state, the support surface 12 is higher than the upper roll surface of the roller 28, when the support plate 11 is in the low position state, the support surface 12 is lower than the upper roll surface of the roller 28.
[0024] For stability, the concave surface of the support surface 12.
[0025] The working principle is as follows:
[0026] In use, such as Figures 2-7 The rotating shaft 10 is fixed on the motor or hydraulic motor, so that the latter can drive the former to rotate, including the following steps:
[0027] S10, the rotating shaft 10 rotates counterclockwise, so that the support plate 11 is in a high position.
[0028] S11, the billet 90 moves forward on the chain conveying table 91, and when it is separated from the chain conveying table 91, it is thrown to the swing baffle 20 by inertia.
[0029] S12, as Figure 7 The billet 90 impacts the swing baffle 20, so that the latter impacts the rear swing baffle 30.
[0030] S13, the horizontal component velocity of the billet 90 is reversed, and at the same time, it continues to fall and finally falls on the support surface 12; at the same time, the swing baffle 20 swings back to the initial position by gravity.
[0031] S14, the rotating shaft 10 rotates clockwise, so that the support plate 11 is in a low position, and the billet 90 falls on the upper roll surface of the roller 28.
[0032] S15, the billet 90 is conveyed to the downstream part through the roller way 21.
[0033] S16, end.
[0034] The characteristics of the patent are:
[0035] S1, the utility model is provided with a swing baffle, and the movement of the swing baffle will consume part of the mechanical energy of the billet. At the same time, the billet is partially buffered, and when the swing baffle impacts the rear swing baffle, the impact force is weakened, so that the rear swing baffle can be prevented from being damaged.
[0036] S2, the utility model is provided with a lower buffer, which will consume part of the mechanical energy of the billet, so that the impact force of the billet is weakened, and the bearing in the roller can be prevented from being damaged.
[0037] Other contents refer to the prior art.
[0038] The above is only the preferred embodiment of the utility model, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the utility model, some changes and improvements can be made, which should also be regarded as the protection range of the utility model.
