Description

Technical Field

[0001] This utility model relates to the field of steel rolling production technology, and in particular to a feeding frame with the function of distinguishing between furnace steel and direct-rolled steel. Background Technology

[0002] During the production of rebar using high-strength steel bars, the production organization mode is a mixed furnace rolling and direct rolling mode. Under this production organization mode, the negative deviation of the finished products from furnace rolling and direct rolling reaches more than 1.5%, which greatly affects the improvement of the overall negative deviation index. The main reason for this is that the surface temperature of direct-rolled steel is low and the core temperature is high, while the surface temperature of furnace-rolled steel is high and the core temperature is low. The oxidation loss of direct-rolled steel is about 3.5‰, while that of furnace-rolled steel is about 7‰. Due to the difference in temperature and oxidation loss, the width of the rolled piece is inconsistent, resulting in dimensional deviations in the finished products of furnace-rolled steel and direct-rolled steel under constant roughing tension. Therefore, it is necessary to feed furnace-rolled steel and direct-rolled steel separately to ensure that they are rolled into different types of finished products separately, avoiding dimensional deviations in the finished products caused by mixing furnace-rolled steel and direct-rolled steel.

[0003] Existing feeding frames that distinguish between furnace steel and direct-rolled steel cannot easily separate the two types of steel during the rolling process, resulting in mixing of furnace steel and direct-rolled steel and dimensional deviations in the finished product.

[0004] Therefore, a feeding frame with the function of distinguishing between furnace-rolled steel and direct-rolled steel is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology is not convenient to distinguish between furnace steel and direct-rolled steel for separate feeding, which leads to the mixing of furnace steel and direct-rolled steel and the resulting dimensional deviations in the rolled products. Therefore, this invention proposes a feeding frame with the function of distinguishing between furnace steel and direct-rolled steel.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a feeding frame with the function of distinguishing between furnace steel and direct-rolled steel, including a first side plate, a first conveyor belt rotatably installed between the two first side plates, a first drive motor installed at one end of the first conveyor belt via a transmission roller, spacer strips uniformly fixed on the outer surface of the first conveyor belt, a separating feeding mechanism installed on both sides of the tail end of the first conveyor belt, a support plate installed on the outer side of the tail end of the first conveyor belt, a receiving groove opened at the top of the support plate, a temperature sensor embedded in the middle of the receiving groove, and a control panel installed on the outer side of the support plate; The separating feeding mechanism includes a second side plate fixed to both sides of the tail end of the first side plate, a second conveyor belt rotatably installed between the two second side plates, a limiting groove evenly opened on the outer surface of the second conveyor belt, a sliding groove opened on the front side of the second side plate and located at the outer end of the receiving groove, and a first elastic pad bonded to the inner side of the second side plate and located opposite the sliding groove.

[0007] Furthermore, the support plate is a rectangular plate structure and is horizontally fixed between the two second side plates. A baffle is fixed at the top of the support plate and at the position outside the receiving groove. The cross-section of the receiving groove is an arc-shaped structure, and the sliding groove is an arc-shaped groove structure.

[0008] Furthermore, the limiting groove has an arc-shaped cross-section, a second drive motor is mounted on one end of the second conveyor belt via a transmission roller, the first elastic pad has a semi-circular structure, and both the sliding groove and the first elastic pad are located above the second conveyor belt.

[0009] Furthermore, a support column is fixed at the top of the second side plate and at the position on both sides of the sliding groove. A mounting plate is fixed at the top of the support column. The mounting plate is horizontally set, and an electric push rod is vertically installed at the middle of its top.

[0010] Furthermore, a connecting plate is fixed at the bottom of the electric push rod and at the outer side of both ends of the support plate. A cylinder is fixedly installed at the bottom middle of the connecting plate, and a telescopic rod is telescopically installed at the front end of the cylinder.

[0011] Furthermore, a first guide rod is fixed at both ends of the connecting plate, and a first guide hole is opened at both ends of the top of the mounting plate, through which the first guide rod slides vertically.

[0012] Furthermore, a telescopic plate is fixed to the outer end of the telescopic rod, and a second guide hole is evenly opened at the top surface of the telescopic plate. A second guide rod slides through the inside of the second guide hole, and a limit nut is connected to the inner end of the second guide rod at the position outside the second guide hole. The second guide rod is a threaded rod structure and is horizontally arranged.

[0013] Furthermore, a push plate is fixed to the outer end of the second guide rod, and a second elastic pad is bonded to the outer side of the push plate. A spring is sleeved on the surface of the second guide rod at the position between the telescopic plate and the push plate. Both the push plate and the telescopic plate are semi-circular plate structures and are vertically arranged at both ends of the receiving groove.

[0014] Compared with the prior art, the present invention proposes a feeding frame with the function of distinguishing between furnace steel and direct-rolled steel, which has the following advantages: 1. This utility model uses evenly fixed spacers on a first conveyor belt to space the furnace steel and the straight-rolled steel for conveying and feeding, avoiding interference and influence between the furnace steel and the straight-rolled steel due to their external surface temperatures. Moreover, the furnace steel and the straight-rolled steel are conveyed by the first conveyor belt and fall into the receiving groove at the top of the support plate. The surface temperature of the furnace steel and the straight-rolled steel is detected by a temperature sensor and the signal is transmitted to the control panel, which facilitates the subsequent differentiation of the furnace steel and the straight-rolled steel according to different temperatures.

[0015] 2. In this utility model, the steel and directly rolled steel fall into the receiving groove inside the furnace. After the temperature is detected by the temperature sensor and control panel, if the surface temperature of the steel bar is low, it indicates that it is directly rolled steel. The control panel then controls the electric push rod at one end of the support plate to move, which in turn moves the connecting plate and the cylinder downward into one end of the receiving groove. At the same time, the cylinder moves the second guide rod, spring and push plate through the telescopic rod and telescopic plate, and pushes one end of the directly rolled steel through the second elastic pad and the push plate, pushing the directly rolled steel through the sliding groove onto the second conveyor belt on one side for feeding. If the steel bar is detected... A high surface temperature indicates that the steel is from the furnace. The electric push rod at the other end of the support plate is controlled by the control panel, which moves the connecting plate and cylinder downwards into one end of the receiving groove. At the same time, the cylinder moves the second guide rod, spring and push plate through the telescopic rod and telescopic plate, and pushes one end of the straight-rolled steel through the second elastic pad and push plate. The straight-rolled steel is pushed through the sliding groove onto the second conveyor belt on the other side for feeding. In this way, furnace steel and straight-rolled steel can be distinguished and fed separately to avoid mixing of furnace steel and straight-rolled steel, which would cause dimensional deviations in the rolled product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] For examples, please refer to Figures 1 to 5 The figure shows a feeding frame with the function of distinguishing between furnace steel and direct-rolled steel, including a first side plate 1, a first conveyor belt 3 rotatably mounted between the two first side plates 1, a first drive motor 2 mounted on one end of the first conveyor belt 3 via a transmission roller, spacer strips 4 uniformly fixed on the outer surface of the first conveyor belt 3, a separating feeding mechanism mounted on both sides of the tail end of the first conveyor belt 3, a support plate 11 mounted on the outer side of the tail end of the first conveyor belt 3, a receiving groove 15 opened at the top of the support plate 11, a temperature sensor 14 embedded in the middle of the receiving groove 15, and a control panel 12 mounted on the outer side of the support plate 11.

[0020] The separating feeding mechanism includes a second side plate 5 fixed to both sides of the tail end of the first side plate 1, a second conveyor belt 7 rotatably installed between the two second side plates 5, a limiting groove 8 evenly opened on the outer surface of the second conveyor belt 7, a sliding groove 9 opened on the front side of the second side plate 5 and located at the outer end of the receiving groove 15, and a first elastic pad 10 bonded to the inner side of the second side plate 5 and located opposite the sliding groove 9.

[0021] The steel in the furnace and the steel rolled in the straight roll are conveyed by the first conveyor belt 3 and fall into the receiving groove 15 at the top of the support plate 11. The temperature of the surface of the steel in the furnace and the steel rolled in the straight roll are detected by the temperature sensor 14 and the signal is transmitted to the control panel 12 so that the steel in the furnace and the steel rolled in the straight roll can be distinguished according to different temperatures.

[0022] The support plate 11 is a rectangular plate structure and is horizontally fixed between the two second side plates 5. A baffle 13 is fixed at the top of the support plate 11 and at the position outside the receiving groove 15. The cross-section of the receiving groove 15 is an arc-shaped structure, and the sliding groove 9 is an arc-shaped groove structure.

[0023] The limiting groove 8 has an arc-shaped cross-section. One end of the second conveyor belt 7 is equipped with a second drive motor 6 via a transmission roller. The first elastic pad 10 has a semi-circular structure. The sliding groove 9 and the first elastic pad 10 are both located above the second conveyor belt 7.

[0024] Support columns 22 are fixed at the top of the second side plate 5 and at the position on both sides of the sliding groove 9. Mounting plate 16 is fixed at the top of the support column 22. The mounting plate 16 is horizontally set and an electric push rod 18 is vertically installed at the middle of its top.

[0025] A connecting plate 23 is fixed at the bottom of the electric push rod 18 and at the outer side of both ends of the support plate 11. A cylinder 19 is fixedly installed at the bottom middle of the connecting plate 23. A telescopic rod 20 is telescopically installed at the front end of the cylinder 19.

[0026] The steel in the furnace and the straight-rolled steel fall into the receiving groove 15. After the temperature is detected by the temperature sensor 14 and the control panel 12, if the surface temperature of the steel bar is low, it indicates that it is straight-rolled steel. The control panel 12 controls the electric push rod 18 at one end of the support plate 11 to run, and drives the connecting plate 23 and the cylinder 19 to move downward into one end of the receiving groove 15.

[0027] The top ends of the connecting plate 23 are fixed with first guide rods 17, and the top ends of the mounting plate 16 are provided with first guide holes 26. The first guide rods 17 slide vertically through the first guide holes 26.

[0028] The telescopic rod 20 is fixed to the outer end of the telescopic plate 21. The top surface of the telescopic plate 21 is evenly provided with second guide holes 27. The second guide rod 29 slides through the inside of the second guide hole 27. The inner end of the second guide rod 29 and the position outside the second guide hole 27 are connected to a limit nut 28. The second guide rod 29 is a threaded rod structure and is set horizontally.

[0029] The outer end of the second guide rod 29 is fixed with a push plate 25. The outer side of the push plate 25 is bonded with a second elastic pad 24. A spring 30 is sleeved on the surface of the second guide rod 29 and located between the telescopic plate 21 and the push plate 25. Both the push plate 25 and the telescopic plate 21 are semi-circular plate structures and are vertically arranged at both ends of the receiving groove 15.

[0030] The cylinder 19 drives the second guide rod 29, spring 30 and push plate 25 to move through the telescopic rod 20 and telescopic plate 21, and pushes one end of the straight-rolled steel through the second elastic pad 24 and push plate 25, pushing the straight-rolled steel through the sliding groove 9 onto the second conveyor belt 7 on one side for feeding.

[0031] Working method: Spacing strips 4 are evenly fixed on the first conveyor belt 3 to place furnace steel and straight-rolled steel at intervals and to transport and feed them, so as to avoid interference and influence between the furnace steel and straight-rolled steel due to their external surface temperatures. Moreover, the furnace steel and straight-rolled steel are transported by the first conveyor belt 3 and fall into the receiving groove 15 at the top of the support plate 11. The temperature of the furnace steel and straight-rolled steel surface is detected by the temperature sensor 14 and the signal is transmitted to the control panel 12, so as to facilitate the subsequent differentiation of furnace steel and straight-rolled steel according to different temperatures.

[0032] The steel in the furnace and the straight-rolled steel fall into the receiving groove 15. After the temperature is detected by the temperature sensor 14 and the control panel 12, if the surface temperature of the steel bar is low, it indicates that it is straight-rolled steel. The control panel 12 controls the electric push rod 18 at one end of the support plate 11 to move, which drives the connecting plate 23 and the cylinder 19 to move downward into one end of the receiving groove 15. At the same time, the cylinder 19 drives the second guide rod 29, the spring 30 and the push plate 25 to move through the telescopic rod 20 and the telescopic plate 21. The cylinder 19 pushes one end of the straight-rolled steel through the second elastic pad 24 and the push plate 25, pushing the straight-rolled steel through the sliding groove 9 onto the second conveyor belt 7 on one side for feeding.

[0033] If a high surface temperature of the steel bar is detected, it indicates that the steel is from inside the furnace. The electric push rod 18 at the other end of the support plate 11 is controlled by the control panel 12 to move, and the connecting plate 23 and the cylinder 19 are moved downward to one end of the receiving groove 15. At the same time, the cylinder 19 drives the second guide rod 29, the spring 30 and the push plate 25 to move through the telescopic rod 20 and the telescopic plate 21. The second elastic pad 24 and the push plate 25 push one end of the straight-rolled steel, pushing the straight-rolled steel through the sliding groove 9 onto the second conveyor belt 7 on the other side for feeding.

[0034] In this way, furnace steel and direct-rolled steel can be distinguished and fed separately, avoiding dimensional deviations in the rolled products caused by mixing furnace steel and direct-rolled steel.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
