Description

Technical Field

[0001] The utility model relates to the technical field of plate rolling machines, and more specifically, to an upper roller locking system of a three-roller asymmetric plate rolling machine. Background Art

[0002] The existing three-roller asymmetric plate rolling machine requires manual loosening of the vertical and horizontal locking pins on the end bracket to fully release one end of the upper roller. Similarly, restoring the upper roller requires reversing the process to reset the upper roller and reinsert the vertical and horizontal locking pins. This cumbersome and time-consuming process significantly impacts efficiency and increases equipment wear. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a three-roller asymmetric plate rolling machine upper roller locking system to solve one or more of the above-mentioned problems.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] The upper roller locking system of a three-roller asymmetric plate rolling machine includes a plate rolling machine with an upper roller. An upper roller mounting groove with a roller unloading opening is provided on the end seat on the roller unloading side of the plate rolling machine. An axis head is provided at the end of the upper roller on the roller unloading side, and a pulling sleeve is provided on the axis head. The pulling sleeve is slidably connected to the outside of the axis head, and the roller unloading opening only passes through the axis head.

[0006] Furthermore, the opening size of the roller unloading opening is smaller than the slot diameter size of the upper roller mounting slot.

[0007] Furthermore, the outer diameter of the shaft head is not larger than the opening size of the roll unloading port, and the outer diameter of the shaft head is smaller than the outer diameter of the upper roller body.

[0008] Furthermore, the inner diameter of the sleeve is not less than the outer diameter of the shaft head, the outer diameter of the sleeve is larger than the opening of the roller unloading port, and the outer diameter of the sleeve is not larger than the slot diameter of the upper roller mounting slot.

[0009] Furthermore, the end of the shaft head and the end surface inside the extraction sleeve are both provided with aligned limiting grooves, limiting screws are embedded in the limiting grooves, and the extraction sleeve and the shaft head are connected via the limiting screws.

[0010] Furthermore, an exhaust gap is left between the limiting screw and the limiting groove, and the diameter of the limiting groove is smaller than the diameter of the bolt cap of the limiting screw.

[0011] In summary, the utility model has the following beneficial effects: by pulling and pushing back the pulling sleeve, the shaft head part can be exposed and hidden, and the unloading roller side of the upper roller is correspondingly in a removable state and a non-removable state, thereby eliminating the loading and unloading action of the unloading roller side, which is more convenient and has less wear.

[0017] Example:

[0018] The following is combined with Figure 1-4 The utility model is described in further detail.

[0019] The upper roller locking system of the three-roller asymmetric plate rolling machine, such as Figure 1 As shown, the plate rolling machine with an upper roller 1 is mainly improved on the unloading side of the upper roller 1 of the three-roller asymmetric plate rolling machine. The end seat 2 on the unloading side of the plate rolling machine was originally designed as a pressure block assembly with a bolt retracted structure. Now, the side of the end seat 2 is opened with an unloading opening 3, which is connected to the upper roller mounting groove 4, providing a way for the unloading side of the upper roller 1 to move outward.

[0020] like Figure 4As shown, both the unloading opening 3 and the upper roller mounting groove 4 are arc-shaped notched grooves. The opening size (diameter) of the unloading opening 3 is smaller than the notch diameter of the upper roller mounting groove 4. This creates a size difference, restricting large-diameter components from passing through the unloading opening 3. The unloading side of the upper roller 1 is improved with a shaft head 5, that is, a stepped roller structure with a large main body diameter of the upper roller 1 and a small shaft head 5. A horizontally sliding sleeve 6 is sleeved over the shaft head 5. The inner diameter of the sleeve 6 is not less than the outer diameter of the shaft head 5, and the outer diameter of the sleeve 6 is larger than the opening size of the unloading opening 3. The outer diameter of the sleeve 6 is not larger than the notch diameter of the upper roller mounting groove 4, and the outer diameter of the shaft head 5 is not larger than the opening size of the unloading opening 3. This ensures that the shaft head 5 can pass smoothly through the unloading side while blocking the main body of the upper roller 1 and the sleeve 6. This allows the sleeve 6 to smoothly transfer the shaft head 5 portion of the upper roller 1 to be installed in the upper roller mounting groove 4.

[0021] like Figure 2 As shown, the end of the shaft head 5 and the end surface of the inner cavity of the sleeve 6 are provided with a limit groove 7, the limit groove 7 is horizontally aligned, the limit groove 7 of the sleeve 6 is threaded and has an exhaust gap, and the two ends of the limit screw 8 are installed in the limit groove 7 of different components, that is, the sleeve 6 and the shaft head 5 are embedded through the limit screw 8. The length of the limit groove 7 is to ensure that the sleeve 6 can be smoothly separated from the shaft head 5 without separation, so that the shaft head 5 can pass through the unloading roller mouth 3 smoothly and unimpeded. The diameter of the limit groove 7 is smaller than the diameter of the bolt cap of the limit screw 8 to prevent the limit screw 8 from being separated from the limit groove 7 and ensure the stability of the structure.

[0022] When using, Figure 1 As shown, the sleeve 6 is pushed to the limit to cover the shaft head 5, and the sleeve 6 is stuck in the upper roller installation groove 4, and the plate rolling machine is used normally. Figure 3 As shown, the sleeve 6 is pulled out in the reverse direction to expose the shaft head 5, and the sleeve 6 is separated from the upper roller installation groove 4. The shaft head 5 leaves the upper roller installation groove 4 along the unloading roller opening 3 as the upper roller 1 rotates horizontally.

[0023] It should be noted that this specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
