Description

Technical Field

[0001] The utility model relates to the technical field of processing guide plates on the conveying side of a continuous casting machine, in particular to a processing device for processing guide plates on the conveying side of a continuous casting machine. Background Art

[0002] In recent years, large steel mills at home and abroad are basically equipped with continuous casting machines, which can be roughly divided into billets and slabs. With the continuous improvement and upgrading of molten steel composition, the production requirements for billets have also become higher, and the production of billets cannot be separated from the assistance of equipment. The billet continuous casting machine mainly includes: ① Casting equipment - ladle transportation equipment, tundish and tundish trolley or rotary table; ② Crystallizer and its vibration device; ③ Secondary cooling device; ④ Billet straightening machine equipment - billet drawing machine, straightening machine, ingot chain, ingot stripping and ingot chain storage device; ⑤ Cutting equipment - flame cutting machine; ⑥ Roller conveyor device; ⑦ Billet discharge equipment, etc.

[0003] Among them, the roller conveyor plays a vital role in the whole system. Once there is a problem with the conveyor, the billet cannot be conveyed normally, which may cause blockage or even shutdown. Therefore, it is particularly important to ensure the normal conveying of the billet. In the process of billet conveying, not only the conveyor roller needs to rotate to drive the billet forward, but also the side must be equipped with a guide plate to guide the billet. Commonly used side guide plates are 7-shaped and 1-shaped.

[0004] At present, the side guide plates (i.e. side guide plates) are usually made by operators themselves due to the large demand and fast wear. The existing production mode is basically: first use a flame cutting gun to cut the steel plate to size, then heat the bending part by flame heating and use a hammer to hit it to achieve the bending purpose. It can be seen that this bending method not only requires the cooperation of multiple people, but also requires a lot of physical strength. At the same time, there are huge safety hazards in the knocking process. And it is easy to cause differences in the bending angle, length, and flatness each time due to uneven human strength during the knocking process, and the processing accuracy of the side guide plate cannot be guaranteed.

[0005] In summary, there is an urgent need for a device that can bend the side guide plate quickly, safely, labor-saving and with guaranteed processing accuracy. Summary of the invention

[0006] The utility model provides a side guide plate bending device for conveying square billets of a continuous casting machine, which can bend the side guide plates quickly, safely, labor-savingly and with guaranteed processing accuracy, thereby effectively solving the problems of great bending difficulty, low processing accuracy and low safety factor in the above-mentioned existing side guide plate manufacturing technology.

[0010] On the same side as the flame cutting gun, an inverted L-shaped connecting rod is vertically arranged above the bending frame, the cross bar of the connecting rod is horizontally perpendicular to the top of the flame cutting gun, and extends outward beyond the flame cutting gun, and the end of the connecting rod is connected to a horizontally arranged nut, and the nut is inserted with a height-fixing screw, and the height-fixing screw passes through the nut and cooperates with another nut to tighten and fix the height;

[0011] Relative to the side where the flame cutting gun is installed, a supporting device for placing a workpiece is provided on the other side of the bending window, and the upper end surface of the supporting device is flush with the lower end surface of the bending window;

[0012] On the same side as the supporting device, a baffle device for preventing the workpiece from sliding is provided on the bending frame.

[0014] Furthermore, the baffle device includes a threaded rod, one end of which is mounted on the bending frame via a nut, and the other end is provided with a baffle vertically arranged therewith, and the baffle is clamped and mounted on the threaded rod via two nuts.

[0015] Furthermore, the baffle device includes a threaded rod, one end of which is mounted on the bending frame via a nut, and the other end is provided with a baffle vertically arranged therewith, and the baffle is clamped and mounted on the threaded rod via two nuts.

[0016] Furthermore, a reinforcing device is provided at the lower end of the bending frame, and the reinforcing device is vertically installed on both sides of the base.

When the bending part collides with the height-fixing screw, the force application and heating are stopped, and the entire bending process is terminated. Therefore, the processing speed is fast and the processing accuracy can be guaranteed. At the same time, the labor intensity of employees is greatly reduced and the safety of personnel is guaranteed.

[0020] 2. The utility model is provided with a support device for placing the workpiece (ie, the side guide plate), so that the downward pressure on the left side of the lever can be effectively supported when the workpiece (ie, the side guide plate) is subjected to bending operation.

[0021] 3. The utility model connects a baffle device to the rear of the bending frame, so that the arrangement can be used to prevent the workpiece (ie, the side guide plate) from sliding during bending, thereby affecting the bending accuracy.

[0022] 4. The baffle device of the utility model can be adjusted forward and backward by rotating two nuts to cope with different types of side guides.

A base 2 is provided on one side of the bottom of the bending frame 1, and a jack 3 is installed above the base 2. The base 2 is mainly used to hold the jack 3 and is in direct contact with the ground to prevent the jack 3 from causing damage to the ground during use.

A sliding pipe 6 is installed above the workpiece (i.e., the side guide plate) 7, and its main function is to support and move the flame cutting gun 5, which can ensure that the workpiece (i.e., the side guide plate) 7 is heated evenly during the heating process, and the labor intensity of employees is reduced, and the flame cutting gun 5 can be heated quickly and effectively by just stroking it with the hand.

[0033] On the same side as the flame cutting gun 5, an upright inverted L-shaped connecting rod 8 is provided above the bending frame 1. The cross bar of the connecting rod 8 is horizontally perpendicular to the top of the flame cutting gun 5 and extends outward beyond the flame cutting gun 5. The end of the connecting rod 8 is connected to a horizontally arranged nut, and the nut is inserted with a height-fixing screw 9. The height-fixing screw 9 passes through the nut and cooperates with another nut to tighten and fix the height. At the same time, by adjusting the height-fixing screw 9, it can be ensured that each workpiece (i.e., the side guide plate) 7 can be bent to the same angle.

[0034] Relative to the side where the flame cutting gun 5 is installed, a supporting device 10 for placing the workpiece (i.e., the side guide plate) 7 is provided on the other side of the bending window 4. The upper end surface of the supporting device 10 is flush with the lower end surface of the bending window 4. The existence of the supporting device 10 can effectively support the downward pressure on the left side of the lever when the workpiece (i.e., the side guide plate) 7 is subjected to a bending operation.

[0035] The supporting device 10 is a triangular supporting frame, and the structure of the triangular supporting frame makes the supporting force of the supporting device 10 more stable.

[0036] On the same side as the supporting device 10 , a baffle device 11 for preventing the workpiece (ie, the side guide plate) 7 from sliding is provided on the bending frame 1 .

The baffle 11-2 of the baffle device 11 can be adjusted forward and backward by rotating the two nuts to cope with different types of workpieces (i.e., side guides) 7, and the adjustment of the baffle 11-2 and the height-fixing screw 9 can further ensure the bending accuracy of the workpiece (i.e., side guide) 7.

[0038] A reinforcing device 12 is provided at the lower end of the bending frame 1 , and the reinforcing device 12 is vertically mounted on both sides of the base 2 , so as to enhance the structural stability.

[0039] The reinforcing device 12 is a triangular reinforcing rib plate.

[0040] The specific process of bending the workpiece (i.e., the side guide plate) 7 using the device of the utility model is as follows:

[0041] like Figure 6 As shown, during use, the workpiece (i.e., side guide plate) 7 is first passed through the bending window 4 opened at the upper end of the bending frame 1 and placed above the supporting device 10, and then the height-fixing screw 9 is adjusted to select a suitable length and angle, and the baffle 11-2 and the nut used therewith are used to rotate the baffle 11-2 and block the workpiece (i.e., side guide plate) 7 from sliding, and then the flame cutting gun 5 is used to heat the part of the workpiece (i.e., side guide plate) 7 to be bent, and finally, when heated to a suitable temperature, the jack 3 is used to apply force to the workpiece (i.e., side guide plate) 7, and the upper part of the jack 3 is in direct contact with the front part of the workpiece (i.e., side guide plate) 7, and a vertical upward pressure is applied to the workpiece (i.e., side guide plate) 7 by hydraulic means to perform a bending operation, and when the bending part collides with the height-fixing screw 9, the force and heating are stopped, and the entire bending process is ended.
