Description

Technical Field

[0001] This utility model relates to a pusher plate for a billet rolling mill, belonging to the technical field of billet rolling mill pusher equipment in the metallurgical industry. Background Technology

[0002] Pushers are arranged at the front and rear of the large bar rolling mill. Their function is to turn and move the billet and align it with the rolling groove for the next rolling pass.

[0003] A pusher plate is mounted at the front of the rolling bed, which is used to push and straighten the rolled workpiece. The pusher plate is a single piece and is a purchased component. During the rolling process, the pusher plate is prone to wear due to frequent contact with the workpiece, necessitating its replacement as a whole. This not only affects production but also significantly increases maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a pusher plate for a billet rolling mill, which adopts a split structure, is sturdy and reliable, easy to replace, reduces costs, and solves the problems existing in the background art.

[0005] The technical solution of this utility model is:

[0006] A pusher plate for a billet rolling mill includes a base plate, a standard panel, countersunk bolts, a wear-resistant panel, a connecting seat, and a positioning sleeve. One side of the base plate is provided with a connecting seat and a positioning sleeve for connecting to the pusher, and the other side of the base plate is provided with a standard panel and a wear-resistant panel. The standard panel and the base plate are connected together by countersunk bolts, and the wear-resistant panel and the base plate are connected together by a mortise and tenon structure.

[0007] A positioning key is provided between the wear-resistant panel and the base plate.

[0008] There are two positioning keys between the wear-resistant panel and the base plate.

[0009] The bottom plate and the wear-resistant panel are respectively provided with arc-shaped grooves that cooperate with the rolled workpiece on the side that contacts the rolled workpiece.

[0010] Both the standard panel and the wear-resistant panel are rectangular plates that fit with the base plate. The positioning sleeve is located in the middle of the base plate, and there are two connecting seats, which are symmetrically arranged on both sides of the positioning sleeve.

[0011] The ordinary panel and the wear-resistant panel are provided with matching tenons and mortises.

[0012] The advantages of this utility model are: it adopts a split structure, which is sturdy and reliable, easy to replace, reduces costs, and avoids scratches on rolled materials. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and examples.

[0022] See attached document Figure 1-7 A pusher plate for a billet rolling mill includes a base plate 1, a standard panel 2, countersunk bolts 3, a wear-resistant panel 6, a connecting seat 10, and a positioning sleeve 11. One side of the base plate 1 is provided with a connecting seat 10 and a positioning sleeve 11 for connection with the pusher. The other side of the base plate 1 is provided with a standard panel 2 and a wear-resistant panel 6. The standard panel 2 and the base plate 1, as well as the wear-resistant panel 6 and the base plate 1, are connected together by countersunk bolts 3. The standard panel 2 and the wear-resistant panel 6 are connected together by a tenon and mortise structure 7.

[0023] In this embodiment, refer to the appendix Figure 1-7 The base plate 1 is a rectangular steel plate made of Q345B with a thickness of 30mm. It is connected to the pusher bed through two connecting seats 10 and a positioning sleeve 11 and moves with the pusher bed.

[0024] The standard panel 2 is a rectangular steel plate, 20mm thick, made of Q345B steel, and is connected to the base plate 1 by three countersunk bolts. The standard panel 2 does not contact the rolled workpiece, hence the use of Q345B material.

[0025] The wear-resistant panel 6 is a rectangular steel plate, 20mm thick, made of 50Mn2 material, and is connected to the base plate 1 by five countersunk bolts. The wear-resistant panel 6 comes into contact with the high-temperature billet and has relative friction with the rolled piece after clamping it. The 50Mn2 material is selected to avoid scratching the billet after wear. Even if the panel is worn, it can be replaced individually, avoiding the need to replace the entire push plate.

[0026] To ensure the connection strength between the base plate 1 and the wear-resistant panel 6, two positioning keys 5 are installed on the base plate 1, which are used to connect it to the wear-resistant panel 6.

[0027] The ordinary panel 2 and the wear-resistant panel 6 are connected together by a tenon and mortise structure 7, which ensures that the wear-resistant panel 6 is not easy to fall off under stress and is easy to position during installation.

[0028] This utility model adopts a split structure of base plate 1, ordinary panel 2 and wear-resistant panel 6, which avoids the need for complete replacement and saves two-thirds of the cost; the connection method of bolts, tenon and mortise structure and positioning key is simple, practical and effective.
