Description

Technical Field

[0001] This application belongs to the field of wire rod production technology, and in particular relates to an inlet and outlet guide for a pre-finishing mill. Background Technology

[0002] In the production of high-speed wire rod, the pre-finishing rolling area is often equipped with alternating horizontal and vertical short-stress rolling mills. Both the front and rear of the mill are equipped with inlet and outlet guides. When the workpiece enters the inlet guide of the next mill from the outlet guide of the previous mill, the guides provide guidance and support, ensuring the workpiece bites into the mill normally and guaranteeing smooth production.

[0003] Currently, most rolling mill guides consist of induction clamps with internal cavities. When using these guides in the production process, as the rolled piece moves from the exit of one rolling mill to the inlet of the next, friction between the rolled piece and the bottom wall of the induction clamp can cause scratches due to the large weight of the rolled piece and the downward bending of its head, affecting the quality of the rolled piece. In severe cases, this can cause sparking in the guide, damaging the rolling mill guide. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this application provides an inlet and outlet guide for a pre-finishing mill, which can prevent the rolled piece from being damaged by friction with the induction clamp and improve the quality of the rolled piece.

[0005] To achieve the above objectives, the technical solution provided in this application is as follows:

[0006] This application provides an inlet and outlet guide for a pre-finishing mill, including an induction clamp, a workpiece sliding along the inner cavity of the induction clamp, a support seat provided on the side of the induction clamp, a horizontal guide wheel rotatably connected to the support seat via an mounting shaft, an opening provided on the induction clamp, the horizontal guide wheel communicating with the inner cavity of the induction clamp through the opening, the horizontal guide wheel being opposite to the inner cavity of the induction clamp and the top surface of the horizontal guide wheel being higher than the bottom wall of the inner cavity of the induction clamp.

[0007] Optionally, the horizontal guide wheel is fixed relative to the mounting shaft, and the mounting shaft is rotatably connected to the support base; or the horizontal guide wheel is rotatably connected to the mounting shaft, and the mounting shaft is fixed or rotatably connected to the support base.

[0008] Optionally, the mounting shaft includes a connected end shaft and an intermediate shaft, which are eccentrically arranged. A horizontal guide wheel is rotatably connected to the intermediate shaft, and the end shaft is connected to the support base.

[0009] Optionally, the end shaft and the support base can be detachably fixed.

[0010] Optionally, the end shaft can be rotated a certain angle and still be fixed on the support.

[0011] Optionally, the horizontal guide wheel is connected to the intermediate shaft via a bearing, wherein the inner ring of the bearing is connected to the intermediate shaft and the outer ring of the bearing is connected to the horizontal guide wheel.

[0012] Optionally, the end shaft is cylindrical.

[0013] Optionally, the support bases are arranged on both sides of the guide clamp, and the two ends of the mounting shaft are connected to the support bases on both sides respectively.

[0014] Optionally, it also includes a guide box and two vertical guide wheels rotatably connected to the guide box. A limiting cavity is formed between the two vertical guide wheels. The limiting cavity is connected to the inner cavity of the induction clamp. The limiting cavity is used to limit the workpiece in the horizontal direction. The limiting cavity is opposite to the horizontal guide wheel.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] This application improves the quality of rolled products by setting a rotating horizontal guide wheel with its top surface higher than the inner cavity bottom wall of the induction clamp. This avoids friction damage between the rolled product and the induction clamp, and changes the sliding friction with the induction clamp to rolling friction with the horizontal guide wheel.

[0017] The mounting shaft of this application adopts an eccentric shaft, with the end shaft and the intermediate shaft eccentrically set. By rotating the end shaft at different angles and fixing it on the support base, the center of the intermediate shaft can be raised to different heights. This allows for adjustment of the center height of the horizontal guide wheel that is rotatably connected to the central shaft and the top surface height of the horizontal guide wheel that contacts the workpiece, facilitating the adjustment of the horizontal guide wheel height. Furthermore, when the horizontal guide wheel wears down after prolonged use and its top surface height becomes insufficient, it is only necessary to rotate the end shaft and re-fix it on the support base.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0024] Example 1

[0025] like Figure 1-2 As shown, a pre-finishing mill inlet and outlet guide includes an induction clamping plate 1. The workpiece slides along the inner cavity of the induction clamping plate 1. A support seat 3 is provided on the side of the induction clamping plate 1. A horizontal guide wheel is rotatably connected to the support seat 3 via an mounting shaft 4. An opening is provided on the induction clamping plate 1. The horizontal guide wheel is connected to the inner cavity of the induction clamping plate 1 through the opening. The horizontal guide wheel is opposite to the inner cavity of the induction clamping plate 1, and the top surface of the horizontal guide wheel is higher than the bottom wall of the inner cavity of the induction clamping plate 1.

[0026] In this embodiment, the horizontal guide wheel is fixed relative to the mounting shaft 4, and the mounting shaft 4 is rotatably connected to the support base 3; or the horizontal guide wheel is rotatably connected to the mounting shaft 4, and the mounting shaft 4 is fixed relative to the support base 3 / or rotatably connected, as long as the horizontal guide wheel can rotate.

[0027] By setting a rotating horizontal guide wheel with its top surface higher than the inner cavity bottom wall of the induction clamp 1, the rolled piece will not directly contact the bottom plate of the induction clamp 1 when passing through it, thus avoiding frictional damage between the rolled piece and the induction clamp 1. The sliding friction with the induction clamp 1 is changed to rolling friction with the horizontal guide wheel, which greatly improves the quality of the rolled piece.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that it also includes a guide box 5 and two vertical guide wheels 2 rotatably connected to the guide box 5. The vertical guide wheels 2 are provided with arc-shaped grooves, and a limiting cavity is formed between the two vertical guide wheels 2. The limiting cavity is connected to the inner cavity of the induction clamping plate 1. The axial direction of the vertical guide wheels 2 is vertical. The limiting cavity is used to limit the workpiece in the horizontal direction to prevent the workpiece from shifting in the left and right directions. The limiting cavity is opposite to the horizontal guide wheel.

[0030] In this embodiment, the support base 3 is fixed on both sides of the induction clamp 1 along the direction perpendicular to the movement of the workpiece, and the two ends of the mounting shaft 4 are connected to the support base 3 on both sides respectively, which is beneficial to the stability of the horizontal guide wheel.

[0031] The mounting shaft 4 includes an intermediate shaft and end shafts 41 fixed at both ends of the intermediate shaft. The end shafts 41 and the intermediate shaft are eccentrically arranged. The horizontal guide wheel is cylindrical. An arc groove can also be opened on the side of the cylindrical guide wheel to facilitate the limiting of the rolled piece. The horizontal guide wheel is rotatably connected to the intermediate shaft (the central shafts 42 of the two coincide). The two end shafts 41 are respectively connected to the support seats 3 on both sides.

[0032] The end shaft 41 is detachably fixed to the support base 3, and the end shaft 41 can still be fixed on the support base 3 even after rotating a certain angle. In this embodiment, the end shaft 41 is cylindrical, so the end shaft 41 can rotate at any angle. In this embodiment, the end shaft 41 is fixed to the support base 3 by a lock nut, but other fixing methods can also be adopted, as long as the detachable fixation between the end shaft 41 and the support base 3 can be achieved.

[0033] The horizontal guide wheel is connected to the intermediate shaft via a bearing, wherein the inner ring of the bearing is connected to the intermediate shaft and the outer ring of the bearing is connected to the horizontal guide wheel.

[0034] In this embodiment, the mounting shaft 4 is an eccentric shaft, with the end shaft 41 eccentrically set to the intermediate shaft. By rotating the end shaft 41 at different angles and fixing it to the support base 3, the center of the intermediate shaft can be raised to different heights. This allows for adjustment of the center height of the horizontal guide wheel rotatably connected to the central shaft 42 and the top surface height of the horizontal guide wheel in contact with the workpiece, facilitating the adjustment of the horizontal guide wheel height. Furthermore, when the horizontal guide wheel wears down after prolonged use, causing its top surface height to be insufficient, simply rotating the end shaft 41 and re-fixing it to the support base 3 will allow the horizontal guide wheel to be readjusted to the appropriate height.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
