Detailed Implementation

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 2 As shown, this embodiment provides a rolling machine for large-walled furnace bodies, including a base 1 on which a support frame 2 is fixedly mounted. Two symmetrically arranged lower drive rollers 3 are rotatably mounted on the bottom of the support frame 2. A lifting hydraulic cylinder 4 is located on both sides of the support frame 2, and its top end is connected to the lower pressure roller 6 through a buffer support 5. A drive mechanism 7 is used to drive the lower drive rollers 3 to rotate. The rolling machine drives the lower pressure roller 6 to move up and down through the lifting hydraulic cylinder 4. At this time, the downward pressure of the lower pressure roller 6 will be provided by the lifting hydraulic cylinder 4, which can ensure a stable and continuous supply of downward pressure.

[0028] The buffer support 5 includes a guide rail plate 51 fixedly mounted on the support frame 2, and a sliding buffer 52 slidably mounted thereon. Its bottom end is fixedly connected to the shaft end of the lifting hydraulic cylinder 4, and its side is rotatably connected to the shaft end of the lower pressure roller 6. In addition, the sliding buffer 52 is provided with a vernier reference mechanism 8. The precise control of the lifting hydraulic cylinder 4 requires a costly control system. Without this system, the lower pressure provided by the lifting hydraulic cylinder 4 may be too large, causing the plate to bend too much and affecting subsequent normal processing. The buffer support 5 can effectively avoid the above problems. The lower pressure on the lower pressure roller 6 will be provided by the sliding buffer 52 in a linearly increasing manner. With the help of the vernier reference mechanism 8, the current lower pressure provided by the sliding buffer 52 can be viewed in real time, which is convenient for adjusting the working condition of the lifting hydraulic cylinder 4.

[0029] like Figure 3 - Figure 4 As shown, the sliding buffer 52 includes an outer frame 521, in which a connecting block 522 for connecting the lower pressure roller 6 is slidably disposed. A guide rod 523 is fixedly disposed on the upper end surface of the connecting block 522, and its top end is in sliding contact with the outer frame 521. A buffer spring 524 is sleeved on the guide rod 523. When the lifting hydraulic cylinder 4 drives the sliding buffer 52 to slide down, the lower pressure roller 6 will move synchronously until it is in contact with the plate. At this time, the lower pressure roller 6 is blocked by the plate and cannot move down, while the sliding buffer 52 as a whole can still move down. There will be a situation where the connecting block 522 does not move while the outer frame 521 moves down as a whole. At this time, the buffer spring 524 is compressed and applies downward pressure to the connecting block 522. The connecting block 522 transmits the downward pressure to the lower pressure roller 6. The above force transmission method can convert the downward pressure provided by the lifting hydraulic cylinder 4 into the downward pressure provided by the buffer spring 524, so that the downward pressure can increase linearly. This makes it convenient for workers to adjust the working condition of the lifting hydraulic cylinder 4 according to the situation, and avoids the situation where the lifting hydraulic cylinder 4 damages the plate due to the lack of a precise control system.

[0030] The two ends of the buffer spring 524 abut against the connecting block 522 and the outer frame 521 respectively, and when the connecting block 522 is located at the lowest position of the outer frame 521, the buffer spring 524 is still in a compressed state, and the above structure can ensure that the buffer spring 524 can provide a certain downward pressure when being in an initial state.

[0031] In addition, the outer frame 521 is provided with a side sliding groove 525 on the side, and the connecting block 522 is fixedly connected with a side sliding block 526 slidingly arranged in the side sliding groove 525, and the above structure can make the sliding of the connecting block 522 more stable and smooth.

[0032] As shown in Figure 4 The cursor reference mechanism 8 includes a pointer 81 and a reference plate 82, wherein the pointer 81 is fixedly arranged at the top end of the guide rod 523, the reference plate 82 is fixedly arranged on the upper end face of the outer frame 521, and the reference plate 82 is provided with a reference scale 83, and the pointer 81 points to the reference scale 83, and when the connecting block 522 slides relative to the outer frame 521, the pointer 81 moves relative to the reference plate 82, and at this time, the value of the reference scale 83 pointed by the pointer 81 changes, so that the compression degree of the buffer spring 524 can be judged, and the size of the downward pressure provided by the buffer spring 524 can be judged.

[0033] As shown in Figure 5 The driving mechanism 7 includes a driving motor 71, the output shaft end of which is fixedly connected with a driving wheel 72, and the shaft end of the lower driving roller 3 is fixedly connected with a driven wheel 73, and the driving wheel 72 and the driven wheel 73 are drivingly connected through a transmission belt 74, and when the driving motor 71 works, it can drive the driving wheel 72 to rotate, and drive the two driven wheels 73 to rotate under the transmission of the transmission belt 74, so as to realize the synchronous and same direction rotation of the two lower driving rollers 3, and provide necessary structural basis for the normal work of the coiling machine.

[0034] As shown in Figure 1 - Figure 2 The supporting frame 2 is provided with a matching groove 21 on both sides, and the groove width is consistent with the diameter size of the shaft end of the downward roller 6 in value, and the matching groove 21 provides necessary structural basis for the upward and downward movement of the downward roller 6; in addition, the base 1 is fixedly provided with a hinged seat 41, and the bottom end of the lifting hydraulic cylinder 4 is rotatably connected with the hinged seat 41, and the above structure provides necessary structural basis for the installation of the lifting hydraulic cylinder 4.

[0035] The use principle and use process of the utility model are as follows:

[0036] The coiling machine drives the downward roller 6 to move up and down through the lifting hydraulic cylinder 4, and at this time, the downward pressure of the downward roller 6 is provided by the lifting hydraulic cylinder 4, which can ensure that the downward pressure is stably and continuously supplied.

[0037] The precise control of the lifting hydraulic cylinder 4 needs a high-cost control system, and if the system is absent, the plate member can be bent too large in size due to the excessive pressing force provided by the lifting hydraulic cylinder 4, which affects the subsequent normal processing, and the buffer support 5 can effectively avoid the above problems, the pressing force borne by the lower pressing roller 6 is provided in a linear growth mode by the sliding buffer 52, and the vernier reference mechanism 8 can be used to view the pressing force provided by the sliding buffer 52 in real time, so as to facilitate the adjustment of the working condition of the lifting hydraulic cylinder 4.

[0038] The above principle is specifically manifested as follows: when the lifting hydraulic cylinder 4 drives the sliding buffer 52 to slide downward, the lower pressing roller 6 moves synchronously until it is attached to the plate member, at this time, the lower pressing roller 6 cannot move downward due to the blockage of the plate member, while the sliding buffer 52 can still move downward as a whole, and the connecting block 522 will not move while the outer frame 521 moves downward as a whole, at this time, the buffer spring 524 is compressed and exerts a pressing force on the connecting block 522, and the connecting block 522 transmits the pressing force to the lower pressing roller 6, the above force transmission mode can convert the pressing force provided by the lifting hydraulic cylinder 4 into the pressing force provided by the buffer spring 524, so that the pressing force can be linearly increased, which facilitates the workers to adjust the working condition of the lifting hydraulic cylinder 4 according to the situation, and avoids the situation that the plate member is pressed to be damaged due to the absence of the precise control system of the lifting hydraulic cylinder 4.

[0039] In the above process, when the connecting block 522 slides relative to the outer frame 521, the pointer 81 moves relative to the reference plate 82, at this time, the value of the reference scale 83 pointed by the pointer 81 changes, so that the compression degree of the buffer spring 524 can be judged, and the size of the pressing force provided by the buffer spring 524 can be judged.

[0040] Finally, it should be noted that: obviously, the above embodiments are only examples for clearly illustrating the utility model, and are not limited to the implementation mode. For ordinary skilled persons in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to exhaust all the implementation modes. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
