Description

Technical Field

[0001] The utility model belongs to the technical field of straightening machine guide plates and relates to a split straightening roller guide plate. Background Art

[0002] Two-roller straightening machines are more common in steel production. The steel passes through the guide sleeves installed on the two-roller straightening machine and enters the paired rollers to straighten and convey the steel.

[0003] The guide plates of the straightening machine are installed at different positions of the straightening machine and have different functions. The main functions include 1) guiding and positioning; 2) controlling deformation; 3) protecting the straightening rollers. For example, when installed at the feeding position, they are mostly used to guide the steel to enter the two-roll straightening machine steadily.

[0004] The guide plates installed on both sides of the rollers mostly serve a protective purpose. On the other hand, the rollers directly squeeze and contact the workpiece, often bringing out waste. If the particles are too large or too abundant, the roller life and performance will be affected. Therefore, the guide plates are required to limit the distance between the rollers and prevent particles from sticking and to clean the surface.

[0005] Most of the guide plates in the existing technology are integrated into the raceway of the two-roll straightening machine, and the corresponding working positions mostly occupy a small area. The working guide plates are in a state of wear and tear after long-term use, and replacement will require replacement of the entire plate, resulting in plate waste; secondly, the surface of the roller needs to be lubricated to extend the extrusion life and ensure the straightening effect of the workpiece.

[0006] Therefore, the present invention designs a split straightening roller guide plate to solve the above problems. Summary of the Invention

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1-4 The figure shows an embodiment of the present invention, a split straightening roller guide plate, comprising a plate 1 and a plate 2, said plate 1 1 and plate 2 2 being detachably connected; said plate 1 1 is provided with positioning holes 3 and connecting holes 4, and each of said positioning holes 3 and connecting holes 4 is provided with multiple groups;

[0041] The second plate 2 is provided with a U-shaped groove 5, and the U-shaped groove 5 is connected to the connecting hole 4 by installing a connecting bolt 6;

[0042] The second plate 2 is provided with a working curved surface 7 , and the working curved surface 7 is suitable for being installed on the bottom of the straightening roller 100 .

[0043] A stepped surface is provided on plate 1, and the connecting hole 4 is installed on the stepped surface; the depth of the positioning hole 3 is greater than the depth of the connecting hole 4; half-open grooves 8 are provided on both plate 1 1 and plate 2 2, and are installed relative to each other; the corresponding half-open grooves 8 are suitable for team installation to form waist-shaped grooves.

[0044] The working curved surface 7 includes a notch portion 71 and two sections 72 . The notch portion 71 and the two sections 72 are connected, and a horizontal length of the notch portion 71 is 5.5 to 7.5 times the horizontal length of the two sections 72 .

[0045] The step surface includes a table top 16 and a table top 2 17 , which are separated and arranged in a strip shape while the table top 2 17 is L-shaped. Both the table top 16 and the table top 2 17 are provided with a half-opening groove 8 .

[0046] This embodiment adopts a split structure, which splits the traditional integral guide plate, wherein plate one and plate two are installed on the step surface, and are threadedly connected by connecting bolts penetrating the U-shaped groove and the connecting hole. A half-groove is designed, and the half-groove groups are installed in pairs. In actual use, the metal of the roller and the workpiece is rigidly squeezed, which will produce a mixture of metal scrap particles and metal oil, lubricating oil, etc. The split installation structure, especially the connecting bolts installed at the top, is prone to accumulation and stacking. As a result, the connecting bolts cannot be removed for maintenance. At this time, the half-groove 8 can be knocked for vibration removal, which is convenient for disassembly. The notch 71 is provided because the rollers of most two-roller straightening machines are installed in pairs at an angle, and the two sets of rollers are installed at an angle. Further, the straightening roller guide is symmetrically installed on the top of the roller, refer to Figure 4 The rollers and straightening roller guides are installed at the bottom, and another set is installed symmetrically at the top. Figure 4 Not drawn.

[0047] Example 2

[0048] like Figure 5-7 FIG. 1 shows another embodiment of the present invention, based on Example 1.

A position hole 9 is provided on the plate 1, and a guide hole 10 and a guide hole 2 11 are provided in the position hole 9. The output groove 73 is connected to the guide hole 2 11, and a nozzle 12 is installed in the output groove 73.

[0049] A fluid delivery tube 13 is installed at the rear end of the nozzle 12, passing through the output slot 73, the second guide hole 11, the position hole 9, and the first guide hole 10. The delivery tube connects to the first plate on both sides and can be connected to an external hydraulic pump or other oil delivery component. The actual pumping structure can be referenced. In actual use, the nozzle orifice should be regularly cleaned during extended use to ensure effective spraying. As the sprayed lubricant rolls along the roller, it will wet the roller along its surface curves.

A folding groove 14 is provided at the bottom of the plate 1, and the folding groove 14 is connected to the guide hole 10; a tube clamp 15 is installed in the folding groove 14, and one end of the tube clamp 15 is fixedly installed on the inner wall of the folding groove 14, and the other end of the tube clamp 15 is suitable for clamping the infusion tube 13. In actual use, the infusion tubes on both sides are easily interfered with, so a folding groove and a tube clamp are provided for fixing and installing the infusion tube. The difference between the pre-Example 2 and the guide hole 10 is as shown in FIG. Figure 9 As shown, the direction changes.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
