DETAILED DESCRIPTION

[0017] EMBODIMENT

[0018] The following will be combined with the Figures 1-3 The utility model will be further described in detail.

[0019] An asymmetric profile bending device of a plate rolling machine, likeFigure 1 As shown, based on the three-roller asymmetric plate rolling machine structure, the main body is an end seat 3 with an upper roller 1, a lower roller 2 and a side roller 13. The upper roller 1, the lower roller 2 and the side roller 13 are all arranged on the plate rolling machine. The upper roller 1, the lower roller 2 and the side roller 13 are additionally provided with an extension section. The upper roller 1 is sequentially provided with a mold mounting section 4 and a manual lifting section 5 which extend out of the end seat 3. The lower roller 2 and the side roller 13 are only provided with the mold mounting section 4 which extends out of the end seat 3. The end portions of the lower roller 2 and the side roller 13 are arranged on a sliding track which tends to be folded towards the center. The end portions of the lower roller 2 and the side roller 13 can be raised and approached or lowered and away by motor equipment. The movements of the lower roller 2 and the side roller 13 can be asynchronous. The upper roller 1 mainly moves horizontally. A special bending mold is butt-jointed on the mold mounting section 4. The mold of the lower roller 2 and the side roller 13 is provided with a recessed ring groove. The outer surface of the mold of the upper roller 1 is a smooth surface. The corresponding thickness of the workpiece is positioned and embedded by the bending mold of the lower roller 2 and the side roller 13. The workpiece is rotated and extruded by the three bending molds driven by the upper roller 1, the lower roller 2 and the side roller 13 to complete the bending of the profile.

[0020] Specifically, the end seat 3 at one end of the dismounting side of the plate rolling machine is provided with a through upper roller mounting groove 6. The dismounting side end of the upper roller 1 is provided with the mold mounting section 4 and the manual lifting section 5 of the extension section. The mold mounting section 4 is arranged in the upper roller mounting groove 6. One side of the upper roller mounting groove 6 is provided with a dismounting opening 7 which penetrates outward. The opening height of the dismounting opening 7 is greater than or equal to the diameter size of the upper roller mounting groove 6, so that the dismounting side of the upper roller 1 can smoothly separate from the dismounting opening 7 in the upper roller mounting groove 6.

[0021] As Figure 3As shown, the outer side of the end seat 3 is provided with two clamping shafts 14 with bolts, the two clamping shafts 14 are annularly distributed along the axis of the upper roller mounting groove 6, and the distribution profile is located outside the groove ring of the upper roller mounting groove 6. The outer side of the end seat 3 is also provided with a locking wrench 8, the inner side of the locking wrench 8 is in close contact with the outer side of the end seat 3. The locking wrench 8 is provided with an upper roller locking groove 10, the side of the upper roller locking groove 10 is provided with a through matching opening 9, and the mold mounting section 4 of the upper roller 1 is inserted into the upper roller locking groove 10 of the locking wrench 8. The neutral line of the upper roller locking groove 10 and the upper roller mounting groove 6 coincides. The outer side of the upper roller locking groove 10 of the locking wrench 8 is provided with a T-shaped embedding groove 15, which is a groove body with a T-shaped cross section, corresponding to the clamping shaft 14, and the end of the clamping shaft 14 with the bolt is embedded in the T-shaped embedding groove 15, which can ensure that the clamping shaft 14 cannot be separated from the T-shaped embedding groove 15, so as to ensure that the locking wrench 8 can be stably connected to the end seat 3. The arc segment of the T-shaped embedding groove 15 and the distribution path of the clamping shaft 14 coincide, which can ensure the smooth degree of the rotation process of the locking wrench 8, and the clamping shaft 14 is annularly distributed along the axis of the upper roller mounting groove 6, so that the locking wrench 8 as a whole can rotate along the axis of the upper roller mounting groove 6, ensuring that the upper roller locking groove 10 and the upper roller mounting groove 6 always share the central axis, and the locking wrench 8 will not hinder the normal use and work of the upper roller 1. Among them, the opening size of the matching opening 9 is greater than or equal to the diameter size of the upper roller locking groove 10, which is also to ensure that the upper roller 1 can smoothly separate from the locking wrench 8 along the matching opening 9 in the upper roller locking groove 10. The depth of the matching opening 9, that is, the transverse length, is less than or equal to the depth of the dismounting roller opening 7, and the upper roller 1 cannot be separated from the end seat 3 without completely separating from the dismounting roller opening 7. The outer side of the end of the locking wrench 8 is provided with an adjusting handle 16 for convenient holding.

[0022] The end seat 3 is provided with two stop blocks 11, which are respectively arranged in the upper half and lower half of the rotation path of the locking wrench 8. Preferably, the upper stop block 11 is arranged such that when the locking wrench 8 abuts against the stop block 11, the opening of the matching opening 9 and the dismounting roller opening 7 are completely aligned, and the lower stop block 11 is arranged such that when the locking wrench 8 abuts against the stop block 11, the matching opening 9 and the dismounting roller opening 7 are in a relatively parallel and mutually blocking state, that is, when the upper roller 1 is separated from the dismounting roller opening 7, it is intercepted by the upper roller locking groove 10 of the wrench.

[0023] The end seat 3 is provided with a bolt groove 12 vertically passing through the dismounting roller opening 7, and a anti-loose bolt is inserted into the bolt groove 12. The anti-loose bolt can prevent the locking wrench 8 from moving outward when the upper roller 1 is locked without installing the bending mold.

[0024] As shown in Figure 2 When the upper roller 1 is dismounted, the anti-loose bolt is removed, and the locking wrench 8 is rotated counterclockwise to abut against the upper stop block 11, at this time the dismounting roller opening 7 and the matching opening 9 are aligned, and the upper roller 1 has no component to hinder its outward movement, so it can be smoothly dismounted. As shown in Figure 1As shown, when the upper roller 1 is locked, the clockwise rotating locking wrench 8 is in contact with the lower stop block 11, the upper roller locking groove 10 of the locking wrench 8 blocks the roller dismounting opening 7, the anti-disengaging bolt is inserted, and the upper roller 1 is locked in the upper roller mounting groove 6 of the end seat 3.

[0025] Because of the design, if the upper roller 1 is fixed, the bending dies of the lower roller 2 and the side roller 13 must be dismounted to take out the processed piece after the profile processing, which is very inconvenient. The upper roller 1 is designed to be provided with the locking wrench 8, and the manual lifting section 5 can realize the mounting and dismounting and horizontal rotation of the upper roller 1 relative to the end seat 3.

[0026] It should be noted that the specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
