Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following describes the technical solution of the present invention with reference to the accompanying drawings and embodiments.
Referring to fig. 1 to 7, the continuous bar rolling forming system includes a plurality of single rolling devices 1 connected in sequence, and the outer diameters of bars rolled and formed by adjacent single rolling devices 1 are gradually reduced. In the process of rolling a rough bar heated to a high temperature state, the rough bar (100 in the figure) is inserted from one end of the first single rolling device 1, under the driving rolling action of the rough bar, the rough bar extends from the other end of the single rolling device 1 and realizes the rolling process of reducing the outer diameter of the rough bar, the extended bar is inserted from one end of the connected single rolling device 1 and extends from the other end, the reducing operation is realized again, and the process is circulated, so that the bar is formed into a rolling forming bar with a small diameter and elongation after passing through a plurality of single rolling devices 1. The operation mode enables the thick bar to be continuously rolled and reduced in diameter, and can be rolled and formed at one time, so that the problems of low operation efficiency, high energy consumption, low transmission efficiency and great potential safety hazard caused by the existing reciprocating operation mode are solved.
After each single rolling device 1 rolls the current bar, the length of the bar has different extension sizes in a state that the outer diameter of the bar is reduced, and the bar continuously enters the connected single rolling devices 1 to cause different rolling speeds and have the problem of extension or extrusion of the bar, so that after the bar is rolled by the single rolling devices 1, the bar enters the next single rolling device 1 again after the tail end of the bar is completely separated, and in order to reduce the temperature loss of the bar in the gap between the adjacent single rolling devices 1, as shown in fig. 6, a heat preservation conveying device 2 is further arranged between the adjacent single rolling devices 1. The bar rolled in the single rolling device 1 at the upstream is wrapped and conveyed through the heat preservation conveying device 2, the bar advancing to the gap is subjected to continuous heat preservation treatment, the bar is prevented from being subjected to too high temperature loss in a plurality of gaps to influence the later-stage roll forming operation, and therefore the final roll forming quality of the bar can be improved.
Specifically, as shown in fig. 5, each of the single rolling devices 1 includes rolling rolls 11 disposed in an up-down symmetrical manner, each of the rolling rolls 11 has a rolling groove 11a, the rolling grooves 11a of the up-down rolling rolls 11 correspond to each other and form a rolling chamber 101, and a driving shaft 12 is disposed on one side of the rolling roll 11. During operation, the driving shaft 12 is driven to rotate, so that the corresponding upper and lower rolling rollers 11 are driven to synchronously rotate, the end part of the bar is inserted from one end of the rolling cavity 101, the rotation of the rolling rollers 11 drives the bar to advance, and single-stage reducing rolling is realized under the extrusion of the external force of the rolling cavity 101.
While the inner diameter of the rolling groove 11a of the rolling roll 11 adjacent to the single rolling device 1 is gradually reduced so that the outer diameter of the bar is gradually reduced to a desired outer diameter after passing through the rolling cavities 101 of the plurality of single rolling devices 1 one by one.
Specifically, as shown in fig. 7, the heat-insulating conveying device 2 includes conveying brackets 21 disposed between adjacent single rolling devices 1, a heat-insulating conveying cylinder 22 (preferably, a heat-insulating material may be disposed on an inner wall of the conveying bracket 21), and conveying rollers 23 extending into the heat-insulating conveying cylinder 22 are disposed at intervals at a bottom of the heat-insulating conveying cylinder 22. After the bar is delivered from the respective rolling chamber 101, its end enters the insulated delivery cylinder 22 and is supported by the delivery rollers 23, and under the driving of the rolling rollers 11 and the inertia of the bar, the bar moves on the delivery rollers 23 and enters the rolling chamber 101 of the next single rolling device 1 to perform the continuous rolling operation.
In order to reduce the energy loss in the whole rolling process, a detection probe 2a extending out of the port of each heat-preservation conveying cylinder 22 close to the single rolling device 1 at the lower stage is arranged at the port of each heat-preservation conveying cylinder, and the rolling forming system further comprises a controller (not shown in the figure). When the bar extends out of the upstream rolling cavity 101, the end of the bar penetrates into the heat-insulating conveying cylinder 22, and when the bar penetrates out of the other end of the heat-insulating conveying cylinder, the detection probe 2a detects the extension of the bar and feeds the bar back to the controller, the controller stops the driving shaft 12 of the single rolling device 1 on the upper side from stopping driving, and simultaneously starts the driving shaft 12 of the single rolling device 1 on the lower side from starting driving, so that the corresponding driving shaft 12 is accurately started according to the advancing position of the bar, compared with the prior art, the single-group driving mechanism is adopted, the working energy consumption is greatly saved, the transmission efficiency is higher, and the running noise of equipment can be effectively reduced.
The principle of the utility model is that: a thick bar heated to a rolling temperature is inserted from one end of a rolling cavity 101 of a first single rolling device 1, the driving shaft 12 is driven to rotate, so that rolling rollers 11 corresponding to the top and the bottom are driven to rotate synchronously, under the external force extrusion of the rolling cavity 101, the bar extends out from the other side, the end of the bar enters a heat preservation conveying cylinder 22 and is supported by a conveying roller 23, under the driving of the rolling rollers 11 and the inertia effect of the bar, the bar moves on the conveying roller 23, after the bar penetrates out from the other end, a detection probe 2a detects the extension of the bar and feeds the extension back to a controller, the controller stops the driving shaft 12 of the upper single rolling device 1 from driving, and simultaneously starts the driving shaft 12 of the lower single rolling device 1 to start driving, so that the driving function of the corresponding driving shaft 12 is accurately started according to the advancing position of the bar, and compared with the prior art that a single group of driving mechanisms is adopted, the energy consumption is greatly saved.
