[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 5 As shown, a plate rolling machine according to an embodiment of the present invention includes: a frame 100, a tilting frame 200, and a roller assembly 300.

[0023] The frame 100 is used to provide a mounting and support carrier for the various components.

[0024] The tilting frame 200 is rotatably connected to the frame 100. The tilting frame 200 is provided with a first support 210 and a second support 220. A rotatable mounting space 230 is defined between the first support 210 and the second support 220. The first support 210 and the second support 220 are configured as separable structures.

[0025] The roller assembly 300 includes a lower roller 310 and an upper roller 320. Two lower rollers 310 are arranged side by side. The lower rollers 310 are rotatably connected to the frame 100. The first end of the upper roller 320 is rotatably connected to the frame 100, and the second end of the upper roller 320 is rotatably inserted into the rotating installation space 230.

[0026] When the first support 210 separates from the second support 220, the tilting frame 200 can rotate to the axial extension path of the exiting upper roller 320 (e.g., Figure 2As shown), so that the formed workpiece can be pulled out along the axial direction of the upper roller 320; it should be noted that when the first support 210 and the second support 220 are not separated, the second end of the upper roller 320 is rotatably inserted into the rotational mounting space 230 between the first support 210 and the second support 220. This engagement will limit the tilting frame 200, and the tilting frame 200 cannot rotate relative to the frame 100. When the first support 210 and the second support 220 are separated, the limit on the tilting frame 200 will be lost, and the tilting frame 200 can rotate relative to the frame 100.

[0027] The plate rolling machine of this utility model, by setting a flipping frame 200 and a separable first support 210 and second support 220, can first separate the first support 210 and the second support 220 when unloading the plate after rolling, so as to avoid interference between the rotation of the flipping frame 200 and the upper roller 320. Then, the flipping frame 200 is rotated to exit the axial extension path of the upper roller 320, so that the second end of the upper roller 320 becomes the free end. Then, the formed workpiece is pulled out from the second end along the axial direction of the upper roller 320, making the unloading operation very convenient.

[0028] It is understandable that the lower roller 310 needs to be equipped with a corresponding power device to drive its rotation, and this power device can take many forms. For example, in one specific embodiment, refer to... Figure 2 As shown, two lower rollers 310 are coaxially connected to driven gears, and a drive motor is installed on the frame 100. A drive gear is connected to the output shaft of the drive motor, and the drive gear meshes with the driven gears on the two lower rollers 310 at the same time.

[0029] Reference Figure 4 As shown, in some embodiments of this utility model, the first support 210 and the second support 220 are respectively provided with semi-circular grooves on opposite sides to jointly define the rotational mounting space 230. The grooves are provided through the upper roller 320 along its axial direction. In addition, it is conceivable that the first end and the second end of the upper roller 320 are provided with bearings, and the second end of the upper roller 320 is rotatably inserted into the rotational mounting space 230 through the bearings.

[0030] Reference Figure 1 As shown, in some embodiments of this utility model, a mounting shaft 130 is provided on the frame 100. The mounting shaft 130 is horizontally arranged, and its central axis is perpendicular to the central axis of the upper roller 320. The bottom end of the tilting frame 200 is rotatably connected to the mounting shaft 130. Furthermore, referring to… Figure 3 As shown, the tilting frame 200 is provided with a mounting groove 201 that extends through the axial direction of the upper roller 320, and the first support 210 and the second support 220 are located in the mounting groove 201.

[0031] It is conceivable that, in order to improve efficiency and equipment stability, a power unit could be provided to drive the tilting frame 200 to rotate. For example, in some embodiments, refer to... Figure 1 and Figure 2 As shown, a telescopic cylinder 140 is provided between the tilting frame 200 and the machine frame 100. The fixed end of the telescopic cylinder 140 is hinged to the machine frame 100, and the telescopic end is hinged to the tilting frame 200. The tilting frame 200 is driven to rotate by the extension and retraction of the telescopic cylinder 140. At the same time, during the plate rolling operation, the telescopic cylinder 140 can also support the tilting frame 200, improving the structural stability of the tilting frame 200. Obviously, the telescopic cylinder 140 can be a hydraulic cylinder or a pneumatic cylinder, and the number of telescopic cylinders 140 can be one or more.

[0032] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, the first support 210 is vertically connected to the tilting frame 200. The tilting frame 200 is also provided with a first drive unit 240, which is connected to the first support 210. The first drive unit 240 is configured to drive the first support 210 to move vertically. In this embodiment, by lifting the first support 210, when the first support 210 and the second support 220 are separated, the first support 210 can be lifted to separate from the upper roller 320, so as to leave a gap to facilitate the rotation of the tilting frame 200.

[0033] In some embodiments, the first drive unit 240 is a hydraulic cylinder or a pneumatic cylinder and is mounted on the top of the tilting frame 200. The first support 210 can be connected to the output shaft of the hydraulic cylinder or the pneumatic cylinder, and the first support 210 and the second support 220 are arranged vertically opposite each other. Relative to the upper roller 320, the first support 210 is on top and the second support 220 is on the bottom.

[0034] Based on the above embodiments, it is conceivable that, in order to achieve the separation of the first support 210 and the second support 220, the second support 220 can be raised and lowered simultaneously with the first support 210. When the first support 210 and the second support 220 are separated, they move in opposite directions. The raising and lowering of the second support 220 can be achieved by a power device or by manual adjustment. For example, a screw can be installed on the second support 220, with the screw vertically passing through the first support 210 and locked with a nut. When it is necessary to separate the first support 210 and the second support 220, the nut is first loosened, causing the second support 220 to move down a certain distance, and then the first support 210 is raised and lowered by adjusting its position.

[0035] Of course, the second support 220 and the first support 210 can also be detachably connected through a connecting structure. When the first support 210 and the second support 220 are separated, the second support 220 can be removed from the first support 210, and then the first support 210 can be raised and lowered until it is separated from the upper roller 320.

[0036] For example, refer to Figures 3 to 5 As shown, in some embodiments of this utility model, the second support 220 is provided with a connecting groove 221 that extends through the axial direction of the upper roller 320, and is slidably sleeved on the first support 210 through the connecting groove 221. A locking mechanism is provided between the first support 210 and the second support 220. The locking mechanism is configured to restrict the sliding of the second support 220 relative to the first support 210, thereby fixing the second support 220 on the first support 210 in conjunction with the connecting groove 221. Obviously, the locking mechanism can release the restriction on the second support 220, so that the second support 220 can slide relative to the first support 210 along the axial direction of the upper roller 320 until the second support 220 separates from the first support 210.

[0037] In some specific embodiments, such as Figure 3 and Figure 5 As shown, the second support 220 has inverted L-shaped structures on opposite sides of the upper roller 320 along the radial direction to form an inverted T-shaped connecting groove 221. The groove of the second support 220 is set in the bottom wall of the connecting groove 221. Obviously, the connecting groove 221 is set as an inverted T-shape to leave room for the first support 210 to connect with the first drive unit 240.

[0038] Reference Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the outer wall of the first support 210 is provided with a locking hole 211 extending radially along the upper roller 320. The locking mechanism includes a locking part 250, which is connected to the second support 220 and can be adjusted radially relative to the second support 220 along the upper roller 320. The locking part 250 is configured to be inserted into the locking hole 211, thereby restricting the sliding of the second support 220 relative to the first support 210 and fixing the second support 220 to the first support 210. When unlocking is required, the locking part 250 is adjusted radially along the upper roller 320 until it is separated from the locking hole 211. It is conceivable that the second support 220 has a clearance structure to avoid the locking part 250, which can be a hole or a groove.

[0039] Reference Figure 4 and Figure 5As shown, in some embodiments of this utility model, the locking part 250 is slidably connected to the second support 220 along the radial direction of the upper roller 320. The locking mechanism also includes an elastic part 260, which is disposed between the second support 220 and the locking part 250. The elastic part 260 is configured to apply an elastic force to the locking part 250 along the radial direction of the upper roller 320 toward the locking hole 211, so that the locking part 250 is inserted into the locking hole 211 under the action of the elastic force. When unlocking is required, only a force opposite to the elastic force of the elastic part 260 needs to be applied to the locking part 250 to disengage the locking part 250 from the locking hole 211, which is very convenient to operate.

[0040] Reference Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the second support 220 is provided with a bracket 222, and the locking part 250 includes a locking rod 251 and a pull ring 253. The locking rod 251 slides through the bracket 222 along the radial direction of the upper roller 320. The bracket 222 is provided with a hole that slides with the locking rod 251. The locking rod 251 is used to insert into the locking hole 211. The outer peripheral wall of the locking rod 251 is provided with a boss 252. The elastic part 260 is provided as a compression spring. The compression spring is sleeved on the locking rod 251, and its two ends abut against the boss 252 and the bracket 222 respectively, so as to apply an elastic force to the locking part 250 along the radial direction of the upper roller 320 toward the locking hole 211. The structure is simple and stable and reliable. The pull ring 253 passes through the locking rod 251 and is located on the side of the bracket 222 away from the compression spring. The pull ring 253 can facilitate the operator to pull the locking rod 251, improving the ease of operation.

[0041] In some specific embodiments, the locking hole 211 extends vertically and is disposed on the upper end face of the first support 210, the bracket 222 is fixed to the upper end face of the second support 220 by screws, the locking rod 251 slides vertically through the bracket 222, and the pull ring 253 is located at the top of the locking rod 251.

[0042] Reference Figure 1 As shown, in some embodiments of this utility model, the frame 100 is provided with a second mounting base 110 and a second drive unit 120. The second mounting base 110 is adjustable in height; the second drive unit 120 is connected to the second mounting base 110 and is configured to drive the second mounting base 110 to move in a vertical position; wherein, the first end of the upper roller 320 is rotatably connected to the second mounting base 110; in this embodiment, by raising and lowering the second mounting base 110 and rotatably mounting the first end of the upper roller 320 on the second mounting base 110, the height of the upper roller 320 can be adjusted by the second drive unit 120 in conjunction with the first drive unit 240 to adapt to plates of different thicknesses or different processing requirements.

[0043] It is conceivable that the second drive unit 120 can be a hydraulic cylinder or a pneumatic cylinder, mounted on the frame 100, with the second mounting base 110 connected to its output shaft. In addition, to improve structural stability, a guide structure can be provided on the frame 100 to guide the lifting and lowering of the second mounting base 110, such as a guide post and guide hole mating structure or a slide groove and slide rail mating structure.

[0044] Reference Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the first end of the upper roller 320 has a balance shaft 321, which extends along the second mounting base 110 in a direction away from the tilting frame 200. The plate rolling machine also includes a balancing mechanism 400, which is configured to apply a downward force to the balance shaft 321. It can be understood that when the tilting frame 200 is tilted to facilitate material handling (e.g. Figure 2 As shown, the second end of the upper roller 320 will lose its support, and the second mounting seat 110 at the first end of the upper roller 320 is not directly fixed to the frame 100, providing limited support for the upper roller 320. This will cause the second end of the upper roller 320 to sink while the first end tilts upward, damaging both the second mounting seat 110 and the second drive unit 120. Therefore, this embodiment provides a balancing mechanism 400 and a balancing shaft 321. The balancing mechanism 400 applies a downward force to the balancing shaft 321 to balance the weight of the second end of the upper roller 320. In addition, when the second support 220 is removed from the first support 210, the balancing mechanism 400 can also apply a downward force to the balancing shaft 321 to avoid excessive friction between the second support 220 and the upper roller 320.

[0045] Reference Figure 1 As shown, in some embodiments of this utility model, the balancing mechanism 400 includes a balancing seat 410 and a third drive unit 420. The balancing seat 410 is vertically connected to the frame 100 and is located on the upper side of the balancing shaft 321. The third drive unit 420 is connected to the balancing seat 410 and is configured to drive the balancing seat 410 to move vertically so that the balancing seat 410 contacts or separates from the balancing shaft 321. Obviously, during processing, the upper roller 320 needs to rotate, at which time the balancing seat 410 can be separated from the balancing shaft 321.

[0046] Reference Figure 2 As shown, in some embodiments of this utility model, the lower end of the balance seat 410 is provided with a groove that matches the balance shaft 321.

[0047] Reference Figure 1As shown, in some embodiments of this utility model, the third drive unit 420 is mounted on the frame 100, the third drive unit 420 is a hydraulic cylinder or a pneumatic cylinder, and the balance seat 410 is connected to the output shaft of the third drive unit 420.

[0048] Understandably, in order to make the vertical movement of the balance seat 410 smoother and more stable, a guide structure can be set between the frame 100 and the balance seat 410, such as a matching structure of guide post and guide hole or a matching structure of slide groove and slide rail.
