Abstract
Description
Technical Field
[0001] The present application relates to the technical field of steel billet production, and in particular to a steel billet waste rejection device. Background Art
[0002] Rebar is an indispensable and important material in the construction of infrastructure such as buildings, bridges, and roads. Its production process involves multiple complex links. In the production process of rebar, steel rolling is a crucial step. In order to ensure that the steel has good plasticity and ductility during the rolling process, the steel billet is usually required to be heated at high temperature in a heating furnace. In actual production, the steel billet is sent into the heating furnace through a conveyor roller. After a period of heating, it is conveyed to the rolling mill for rolling. Due to uncontrollable factors in the lifting, cooling and other links, the steel billet is prone to bending and deformation during the heating and transportation process, forming bent billets of various shapes. These bent billets are often unevenly stressed during the subsequent transportation process due to their irregular shapes, which brings additional load to the conveyor roller and even causes overload and power outages.
[0003] In the related technology, since the two ends of the bent blank protrude downward in the middle and their force-bearing surface is small, the traditional steel-pushing scrap rejection device is difficult to fit tightly with the bent blank during the advancement process, resulting in the two ends of the bent blank easily sinking during the advancement process, and then getting stuck with the scrap rack. This blocking phenomenon will not only cause the production line to stop for a long time, increase maintenance costs and production costs, but also seriously affect production efficiency and bring unnecessary economic losses to the company, so it needs to be improved. Utility Model Content
[0004] In order to solve the problem that conventional steel-pushing waste rejection devices are prone to jamming, the present application provides a steel blank rejection device.
[0005] The present application provides a steel billet rejection device that adopts the following technical solution:
[0006] A steel billet rejection device comprises a bracket arranged on one side of a roller, a billet receiving frame is arranged on the top of the bracket, the upper end of the billet receiving frame is arc-shaped, a hydraulic cylinder is arranged at the bottom of the bracket, a waste rejection support arm is hingedly provided at the output end of the hydraulic cylinder, the waste rejection support arm is L-shaped, the middle section of the waste rejection support arm is hinged to the bracket, and the material receiving end of the waste rejection support arm is arranged toward the roller direction.
[0007] Since the two ends of the bent billet protrude downward in the middle and have a small force-bearing surface, it is difficult for the traditional steel-pushing type scrap rejection device to fit tightly with the bent billet during the advancement process, resulting in the two ends of the bent billet easily sinking during the advancement process, and then getting stuck with the scrap stand. This blocking phenomenon will not only cause the production line to stop for a long time, increase maintenance costs and production costs, but also seriously affect production efficiency, causing unnecessary economic losses to the company; by adopting the above technical solution, including a bracket, a billet receiving frame is installed on the top of the bracket, the hydraulic cylinder is located at the bottom of the bracket, and the scrap rejection support arm is hingedly installed at the output end of the hydraulic cylinder; when the steel billet is rejected, on the steel billet production line, when the unqualified steel billet moves forward with the roller to the scrap rejection area, the hydraulic cylinder receives a start signal and starts working, and the hydraulic cylinder generates a strong The thrust of the scrap rejection support arm pushes the articulated scrap rejection support arm to rotate, and the receiving end of the scrap rejection support arm (i.e., the end away from the hinge point) gradually rotates upward and approaches the steel billet on the roller. The receiving end of the scrap rejection support arm contacts the steel billet and continues to rotate upward. The steel billet is gently lifted up and separated from the support of the roller by the lever principle. The steel billet is stably placed on the scrap rejection support arm and gradually rises with the further rotation of the scrap rejection support arm. With the continuous rotation of the scrap rejection support arm, the steel billet is smoothly lifted to the top of the billet receiving frame and finally placed on the billet receiving frame. At this point, the entire scrap rejection workflow is completed, and the unqualified steel billet is successfully rejected and safely placed on the billet receiving frame to wait for subsequent processing. At the same time, the scrap rejection device is quickly reset to prepare for the next steel billet to be rejected.
[0008] Through the arrangement of the steel billet receiving frame, hydraulic cylinder and scrap rejection arm, the L-shaped design of the scrap rejection arm increases the contact area with the steel billet, so that even in the face of severely deformed bent billets, a tight fit can be achieved, effectively reducing the difficulty in rejecting scraps caused by the irregular shape of the steel billet. The steel billet receiving frame adopts an arc-shaped design, which echoes the moving trajectory of the scrap rejection arm, reducing the friction and collision between the steel billet and the device during the scrap rejection process, greatly reducing the occurrence of jamming. During the whole process, the steel billet remains stable and is not prone to sinking or shifting, avoiding jamming with the scrap stand, reducing downtime, improving production efficiency, reducing equipment failure rate, and thus reducing maintenance costs.
[0009] Optionally, the waste rejection supporting arm is provided with an anti-falling portion for preventing the embryo from falling, and the anti-falling portion is arranged at the material receiving end of the waste rejection supporting arm.

[0011] Optionally, the material receiving end of the waste rejection supporting arm is lower than the roller plane.
[0012] By adopting the above technical solution, the material receiving end of the scrap rejection arm is lower than the roller plane; by setting the position of the scrap rejection arm, since the material receiving end of the scrap rejection arm is lower than the roller plane, when the scrap rejection arm starts to rotate and contact the steel billet, the contact point first occurs at the bottom of the steel billet, which enables the steel billet to be lifted more smoothly, reduces friction and resistance during the scrap rejection process, makes the scrap rejection action smoother, ensures that the steel billet will not slip or fall off during the scrap rejection process, and improves the success rate of scrap rejection.
[0013] Optionally, a surface of the embryo receiving frame is provided with an anti-falling protrusion, and the anti-falling protrusion is arranged at the material receiving end of the embryo receiving frame.
[0014] By adopting the above technical solution, the anti-fall protrusion is integrally formed on the surface of the embryo receiving frame; through the setting of the anti-fall protrusion, the anti-fall protrusion acts as a physical barrier, which can directly prevent the steel embryo transferred from the scrap rejection arm to the embryo receiving frame from slipping or falling due to unexpected circumstances (such as equipment failure, operating error, etc.), thereby greatly reducing the risk of the steel embryo falling and enhancing the anti-fall safety.
[0015] Optionally, a bearing seat is provided on the bracket, a long shaft is rotatably provided on the bearing seat, and a through hole for installing the long shaft is opened in the middle section of the waste rejection support arm.
[0016] By adopting the above technical solution, the bearing seat is installed on the bracket, the long axis is installed on the bearing seat through the bearing, and the waste rejection arm is installed on the long axis; through the setting of the bearing seat and the long axis, it is ensured that the steel blank can be accurately and stably lifted and transferred to the blank receiving frame, thereby improving the flexibility of the waste rejection arm and reducing vibration and shaking during the waste rejection process.
[0017] Optionally, the bearing seat is provided with a plurality of fixing bolts for fixing to the bracket, and the plurality of fixing bolts are arranged in sequence on the bearing seat.
[0018] By adopting the above technical solution, the bearing seat is installed on the bracket by fixing bolts; the setting of the fixing bolts ensures the stability of the bearing seat during the waste rejection process, prevents loosening or falling off due to vibration or impact, and facilitates installation and disassembly.
[0019] Optionally, a cylinder base is provided outside the hydraulic cylinder, the cylinder base is connected to the ground, and the cylinder body of the hydraulic cylinder is hingedly mounted on the cylinder base.
[0020] By adopting the above technical solution, the hydraulic cylinder is installed on the cylinder base; through the setting of the cylinder base, the cylinder base serves as a support structure for the hydraulic cylinder, which can bear the huge weight and working pressure generated during the working process of the hydraulic cylinder, ensuring the stability of the hydraulic cylinder during high-speed and high-load operation, and reducing displacement or damage caused by vibration or impact.

[0039] The implementation principle of a steel billet rejection device in the embodiment of the present application is as follows: when rejecting steel billets, on the steel billet production line, when unqualified steel billets move forward with the roller table 2 to the rejecting area, the hydraulic cylinder 4 receives a start signal and starts working, and the hydraulic cylinder 4 generates a strong thrust to push the rejecting support arm 5 hinged thereto to rotate, and the material receiving end of the rejecting support arm 5 (i.e., the end away from the hinge point) gradually rotates upward and approaches the steel billet on the roller table 2, and the material receiving end of the rejecting support arm 5 contacts the steel billet and continues to rotate upward, and the lever principle is used to push the rejecting support arm 5 to the rejecting area.
