Description

Technical Field

[0001] The utility model belongs to the field of bulb flat steel production, in particular to an embedded and detachable hole-type guide plate device for hot-rolled bulb flat steel. Background Art

[0002] In the hot rolling production of bulb flat steel, the guide plate device installed at the hole entrance is arranged on both sides of the bulb flat steel to guide the rolled piece into the hole. The existing guide plate device includes a guide plate beam and a guide plate fixed on the guide plate beam, and the guide plate is arranged along the conveying direction of the rolled piece. During the rolling process, one side of the ball head directly contacts and rubs with the inner working surface of the guide plate, damaging the surface of the guide plate. If the guide plate is not replaced in time, it will scratch the rolled piece, directly affecting the surface quality of the rolled piece. Since the rolled piece on one side of the ball head is in line contact with the guide plate, the guide plate wears faster, increases the consumption and replacement frequency of the guide plate, and the guide plate needs to be replaced as a whole after wear, which is costly. In order to meet the replacement conditions, multiple sets of guide plate spare parts need to be equipped according to different rolling varieties, resulting in increased costs. In addition, each time the guide plate is replaced, the guide plate needs to be removed from the guide plate beam as a whole, and the guide plate needs to be adjusted during installation, which is time-consuming and labor-intensive, restricting production efficiency. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of the utility model is to provide a hot-rolled ball flat steel embedded detachable hole-type guide plate device, which adopts a split structure guide plate and contacts the hot-rolled workpiece with a wear-resistant plate. After wear, only the wear-resistant plate needs to be replaced, and replacement is convenient.

[0004] To achieve the above purpose, the utility model is implemented through the following technical solutions:

[0005] A hot-rolled ball flat steel embedded detachable hole-type guide plate device comprises a guide plate 1, a guide plate 2, a wear-resistant plate and fasteners. The guide plate 1 and the guide plate 2 are installed on both sides of a running channel of a rolled piece at the entrance of a rolling mill.

[0025] The present invention is described in detail below in conjunction with the accompanying drawings of the specification, but it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0026] Example 1

[0027] See Figure 1-Figure 5 The embedded detachable hole-type guide plate device for hot-rolled bulb flat steel includes a guide plate 1, a guide plate 2, a wear-resistant plate 3, and a fastener 4. The guide plate 1 and the guide plate 2 are installed on both sides of the running channel of the rolled piece 9 at the entrance of the rolling mill and are fixedly connected to the guide plate beam. The guide plate 1 and the guide plate 2 are arranged opposite to each other. A groove 7 is opened on the inner side of the guide plate 1, and the groove 7 is arranged along the running direction of the rolled piece 9. A wear-resistant plate 3 is arranged in the groove 7. The wear-resistant plate 3 contacts one side of the ball head of the rolled piece 9. The wear-resistant plate 3 is fixedly connected to the guide plate 1 through the fastener 4. When producing bulb flat steels of adjacent models, it is sufficient to replace the corresponding guide plates. For example, after producing 24# bulb flat steel, it is necessary to produce 22# bulb flat steel. It is sufficient to replace the corresponding guide plates. The wear-resistant plates 3 adopt the same size to improve their versatility.

[0028] Example 2

[0029] Based on Example 1, see Figure 4 , Figure 5 The fastener 4 adopts a screw 6 and a nut 5, one end of the screw 6 is welded to the wear-resistant plate 3, at least two through holes are opened at the bottom of the groove 7 of the guide plate 1, and the other end of the screw 6 passes through the through holes and is connected to the nut 5, so that the wear-resistant plate 3 is fixed in the groove 7 of the guide plate 1.

[0030] Example 3

[0031] Based on Example 1, see Figure 6 , Figure 7 The fastener 4 is a hexagonal bolt 8 and a nut 5. The bottom of the groove 7 of the guide plate 1 is provided with a hexagonal mounting hole. The head of the hexagonal bolt 8 is welded to the wear-resistant plate 3, and the tail passes through the mounting hole and is connected to the nut 5. The hexagonal mounting hole is matched with the head of the hexagonal bolt 8 to improve the matching accuracy between the guide plate 1 and the wear-resistant plate and reduce the matching clearance.

[0032] The wear-resistant plate 3 of the above embodiment can adopt an L-shaped structure. The side of the wear-resistant plate 3 is attached to the bottom of the groove and fixed to the guide plate 1. The bottom of the wear-resistant plate 3 plays a supporting role before the tied piece enters the hole mold from the transport roller, preventing the tied piece from getting stuck due to up and down shaking when entering the hole mold, ensuring that the tied piece bites smoothly and stably.

[0033] When the wear-resistant plate 3 in direct contact with the rolled piece 9 is seriously worn, the nut 5 is removed during the production interval, the wear-resistant plate 3 is directly pulled out, the wear-resistant plate 3 is removed from the guide plate 1, and a new wear-resistant plate 3 is replaced. The screw 6 or bolt 8 is inserted into the guide plate 1, and the nut 5 is tightened. The production can be resumed immediately. The replacement is very convenient, and the replacement time does not exceed 5 minutes. There is almost no impact on production. The wear-resistant plate 3 is small in size, light in weight, and low in cost, which is convenient for manual replacement. The replaced wear-resistant plate 3 can be repaired and put back into use according to the wear condition, further reducing the production cost.

[0034] The utility model has a simple and reasonable structure and adopts a detachable wear-resistant plate 3 structure. When the wear-resistant plate 3 is damaged, there is no need to remove the guide plate, and only the wear-resistant plate 3 needs to be replaced, thereby reducing the consumption and replacement frequency of the guide plate. When producing adjacent types of bulb flat steel, the same guide plate can be used, and only the wear-resistant plate 3 needs to be replaced, thereby improving applicability, reducing guide plate spares, and reducing production costs. The use of the wear-resistant plate 3 can more accurately guide the bite of the rolled piece 9, and the bite is smooth and stable, reducing steel jamming accidents, improving product yield, and improving production efficiency. The wear-resistant plate 3 is used to directly contact and rub with the hot-rolled piece 9, so replacement is very convenient, the number of maintenance personnel required is small, the labor intensity is greatly reduced, and the maintenance cost is low.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] Through the above specific implementations, those skilled in the art can easily implement the utility model. However, it should be understood that the utility model is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
