[0018] In the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0019] like Figure 1 As shown, a feeding guide device for a straightening machine comprises a feeding table 2 and two guide plates 3 distributed on both sides of the feeding port of the straightening machine 1 and arranged in a trumpet shape. From the feeding table to the straightening machine, the distance between the two guide plates gradually decreases until they are matched and connected with the feeding port of the straightening machine. One end of each guide plate away from the straightening machine is rotatably connected to a positioning shaft 4 arranged on the feeding table. One end of each guide plate is connected to a sleeve 301, which is sleeved on the outside of the positioning shaft 4 and rotatably connected thereto. An adjusting screw 5 is rotatably connected to the outer side of the other end of the guide plate. The adjusting screw is threadedly connected to a fixing seat 6 arranged on the feeding table. The adjusting screw passes through a threaded hole on the fixing seat, and its end is rotatably connected to the corresponding guide plate, so that the guide plate can be driven to move during rotation. The central axis of the adjusting screw is perpendicular to the feeding direction of the straightening machine. By screwing the adjusting screw, the swing of the guide plate can be controlled, thereby adjusting the distance between the two guide plates to meet the use requirements of products of different specifications and sizes. The adjustment process is simple and convenient, which greatly improves the production efficiency. In order to achieve accurate feeding, a guide plate 9 with an inclined upper end surface is provided between the two guide plates. The two guide plates are pressed on the guide plates and slide horizontally along their upper surfaces. The guide plates can accurately feed the steel into the feeding port of the straightening machine.

[0020] The guide plate is prone to wear and damage during long-term use. In order to facilitate regular maintenance, each guide plate is connected by bolts at both ends through a fixed seat, a positioning plate, and an adjustment plate, which is easy to disassemble and assemble. Among them, a first waist-shaped hole 601 is provided on the fixed seat, and the first waist-shaped hole is a strip hole, and its length direction is parallel to the feeding direction of the straightener, that is, perpendicular to the central axis of the adjusting screw. A positioning plate connected to the feed table by bolts is connected to one side of each positioning shaft, and a second waist-shaped hole is provided on the positioning plate, and the second waist-shaped hole is a strip hole, and its length direction is parallel to the feeding direction of the straightener. An adjustment plate 8 connected by bolts is provided between the positioning plate and the feed table, and a third waist-shaped hole 801 is provided on the adjustment plate, and the third waist-shaped hole is a strip hole, and its length direction is perpendicular to the feeding direction of the straightener. Bolt mounting holes matching the second waist-shaped hole are provided on the adjustment plate and the feed table, and bolt mounting holes matching the first waist-shaped hole and the third waist-shaped hole are also provided on the feed table.

[0021] The method of using the utility model is as follows:

[0022] like Figure 1 As shown, according to the actual product processing requirements, the two guide plates 3 are respectively installed on the feed table 2 by bolt assembly through the fixing seat 6, the positioning plate 7 and the adjusting plate 8, and the two guide plates 3 are distributed in a trumpet shape on both sides of the feeding port of the straightening machine 1. When the product specifications change, the end distance between the two guide plates 3 can be adjusted by screwing the adjusting screw 5, which is simple and convenient to operate.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
