Description
Technical Field
[0001] The utility model relates to the technical field of ribbed steel production equipment, and particularly relates to a short-length ribbed steel rejection device. Background Art
[0002] With the development of the steel industry and the improvement of customers' usage requirements, there are relatively high requirements for the uniformity and standard of the specified length of ribbed steel. However, in the ribbed steel rolling and processing industry, due to various reasons such as equipment failures and improper control of the shearing process, there will be some short-length ribbed steels whose lengths do not meet the specified requirements. In traditional rolling mills, manual selection and rejection are usually required. This method is inefficient, increases the labor intensity of workers, and there are certain risks. Therefore, developing a device that can reject short-length ribbed steels is of great significance for improving production efficiency and reducing labor intensity. Content of the Utility Model
[0003] The purpose of the utility model is to provide a short-length ribbed steel rejection device, which can conveniently reject short-length ribbed steels, improve production efficiency, and reduce labor intensity.
[0004] The above technical purpose of the utility model is achieved through the following technical solutions:
[0005] A short-length ribbed steel rejection device includes a conveying device, in which a lifting baffle and a braking device are provided. The lifting baffle is driven to move up and down by a driving device. After descending, it allows the conveying device to convey the ribbed steel forward. The ribbed steel with its tail end completely leaving above the lifting baffle is short-length ribbed steel, and the ribbed steel with its tail end still located above the lifting baffle is long-length ribbed steel. After the lifting baffle rises, it lifts the long-length ribbed steel upward until it abuts against the lower part of the braking device, and brakes the long-length ribbed steel between the lifting baffle and the braking device, allowing the short-length ribbed steel to continue to be conveyed forward through the conveying device.
[0006] By adopting the above technical solutions, after the passing length of the ribbed steel on the conveying roller path reaches the set distance, the lifting baffle is controlled to rise, and the long-length ribbed steel is braked and waited through the braking device above, and the short-length ribbed steel passes through the conveying roller path, thereby realizing automatic rejection, significantly improving production efficiency and reducing labor intensity.
[0007] Furthermore, the conveying device includes a plurality of distributed conveying roller paths, and the lifting baffle is located between two adjacent conveying roller paths.
[0008] By adopting the above technical solutions, a plurality of conveying roller paths convey the ribbed steel forward in sequence, pass through the lifting baffle, and wait for the lifting baffle to rise, and cooperate with the braking device to realize screening.
[0009] Furthermore, the driving device includes two cylinders, and the output ends of the cylinders are connected upward to the lifting baffle.
[0010] By adopting the above technical solution, the air cylinder drives the lifting baffle plate to realize the departure of the threaded steel from the lifting baffle plate and the braking of the long-length threaded steel.
[0011] Furthermore, it includes several detection devices. After detecting that the head end of the threaded steel moves to a set distance, the lifting baffle plate rises.
[0012] By adopting the above technical solution, the automatic detection of the movement of the threaded steel is realized. After detecting that the head end of the threaded steel moves a set distance, the lifting baffle plate is driven to act, and the short-length threaded steel is automatically removed, further reducing the labor intensity.
[0013] Furthermore, the braking device includes a brake plate, and the conveying device passes the threaded steel between the lifting baffle plate and the brake plate.
[0014] By adopting the above technical solution, the lifting baffle plate abuts the long-length threaded steel upward under the brake plate to make it brake and stop, while the short-length threaded steel continues to be conveyed forward by the conveying device.
[0015] Furthermore, the braking device further includes fixed rods and elastic buffer members. There are two fixed rods, and both ends of the brake plate are slidably connected up and down to the corresponding fixed rods, and the elastic buffer members abut against the upper side of the brake plate.
[0016] By adopting the above technical solution, the elastic buffer members realize the buffering of the threaded steel, reducing the occurrence of the situation of bending the steel during the process of the lifting baffle plate pushing the steel up.
[0017] Furthermore, the elastic buffer members include buffer springs. The buffer springs are sleeved on the fixed rods, and abutting blocks are provided on the fixed rods. Both ends of the buffer springs respectively abut between the abutting blocks and the brake plate.
[0018] By adopting the above technical solution, the buffer springs press the brake plate tightly on the upper side of the threaded steel to realize the braking of the threaded steel, avoiding the bending of the steel during the process of pushing it up.
[0019] Furthermore, the conveying roller path includes a conveying body. A limiting groove is provided in the conveying body, and rollers are provided at the bottom of the limiting groove. Both ends of the conveying body are connected to the fixed rods, and the elastic buffer members drive the brake plate to abut downward at both ends of the conveying body.
[0020] By adopting the above technical solution, both ends of the brake plate abut downward at both ends of the conveying body through the elastic buffer members. The threaded steel is limited in the middle limiting groove and is conveyed forward through the rollers. After the lifting baffle plate rises, the threaded steel is abutted upward against the lower side of the brake plate.
[0021] Furthermore, the braking device is located in front of the lifting baffle plate in the conveying direction.
[0022] By adopting the above technical solution, it is ensured that after the lifting baffle plate is lifted and lowered, the long-scale deformed steel bars that meet the requirements can be abutted against the lower part of the braking device.
[0023] Furthermore, the horizontal distance between the braking device and the lifting baffle plate is 50 cm.
[0024] By adopting the above technical solution, while ensuring the braking effect, the buffering effect on the deformed steel bars is also taken into account.
[0025] In summary, the present utility model has the following beneficial effects:
[0026] The short-scale deformed steel bar removing device of the present utility model automatically detects the passing length of the deformed steel bars on the conveying roller table through a detection device. When the deformed steel bars are detected, the control system controls the lifting baffle plate to rise, brakes the long-scale deformed steel bars for waiting, and the short-scale deformed steel bars pass through the conveying roller table, thereby realizing automatic removal. This device has the advantages of simple structure, convenient operation, high degree of automation, etc., and can significantly improve production efficiency and reduce labor intensity.

[0030] The following further describes the specific embodiments of the present utility model with reference to the drawings. This embodiment does not constitute a limitation to the present utility model. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.
[0031] A short-scale deformed steel bar removing device, as Figure 1 and Figure 2 shown, includes a conveying device for continuously conveying the deformed steel bars sheared by a cold shear machine to a detection area to ensure that the deformed steel bars maintain a stable posture during the conveying process;
[0032] The conveying device is provided with a lifting baffle 2 and a braking device 3. The lifting baffle 2 is driven by a driving device to move up and down. After it descends, the conveying device is used to convey the deformed steel bars forward. When the head end of the deformed steel bar leaves a set distance, if the tail end completely leaves above the lifting baffle 2, it is a short-length deformed steel bar; if the tail end still remains above the lifting baffle 2, it is a long-length deformed steel bar. After the lifting baffle 2 rises, it lifts the long-length deformed steel bar upward until it abuts against the lower part of the braking device 3, and brakes the long-length deformed steel bar between the lifting baffle 2 and the braking device 3, so that the short-length deformed steel bars can continue to be conveyed forward through the conveying device.
[0033] As Figure 2 shown, the conveying device includes a number of distributed conveying roller paths 1. The lifting baffle 2 is arranged between two adjacent conveying roller paths 1 according to the position of the finishing cooling bed; the conveying roller path 1 includes a conveying body, and a limiting groove 11 is provided in the conveying body. A roller body is installed at the bottom of the limiting groove 11. The roller body can be set to rotate partially or entirely driven by a motor. The deformed steel bars are limited in the limiting groove 11 and are conveyed forward by the roller body.
[0034] As Figure 1 shown, the driving device of the lifting baffle 2 includes a pair of cylinders 21. The output ends of the cylinders 21 are connected upward to the corresponding ends of the lifting baffle 2 to achieve rapid lifting and lowering. This structure can be used as the structure of both the head-aligning baffle and the lifting braking device 3 at the same time; the braking device 3 is located in front of the lifting baffle 2 in the conveying direction. In this embodiment, the horizontal distance between the braking device 3 and the lifting baffle 2 is 50 cm.
[0035] As Figure 1 shown, the braking device 3 includes a braking plate 31. The conveying roller path 1 passes the deformed steel bars through between the lifting baffle 2 and the braking plate 31; the braking device 3 further includes fixing rods 32 and elastic buffer members. There are two fixing rods 32, and both ends of the braking plate 31 pass through and are slidably connected up and down to the corresponding fixing rods 32, and the elastic buffer members abut against the upper side of the braking plate 31;
[0036] In this embodiment, the elastic buffer member includes a buffer spring 33. Both ends of the conveying body are connected to the fixing rods 32. The buffer spring 33 is sleeved on the fixing rods 32. An abutting block 34 is provided on the fixing rods 32. Both ends of the buffer spring 33 respectively abut between the abutting block 34 and the braking plate 31. The abutting block 34 can be a structure such as a nut threadedly connected to the top of the fixing rod 32; the buffer spring 33 drives the braking plate 31 to abut downward against both ends of the conveying body, so that together with the limiting groove 11, a space for the normal passage of the deformed steel bars is formed.
[0037] As Figure 1As shown, in other embodiments, the rejection device may further include a number of detection devices 4, such as an infrared detection signal instrument. When the deformed steel bar is detected at a set distance position, it means that its head end has moved from the lifting baffle 2 to the set distance. At this time, the lifting baffle 2 is controlled to rise;
[0038] According to the common specified lengths (9m, 12m), detection devices 4 can be respectively arranged on both sides of the conveying roller path 1 at 6m and 8m behind the lifting baffle 2 to detect the length of the deformed steel bars passing through, and short-length deformed steel bars within 6m and 8m can be respectively rejected. The positions of the detection devices 4 can also be adjusted according to experience and tests, etc.;
[0039] The detection device 4 can adopt existing high-precision measuring equipment such as an infrared sensor to ensure the accuracy of the measurement results. The detection device 4 is non-contact type, and it can also be replaced with a contact type structure such as a lifting flush baffle. By means of a pressure sensor or periodic startup, etc., the head end of the deformed steel bar is abutted against this, and then the tail end is clamped and braked. Then the flush baffle descends and continues to convey to complete the short-length screening.
[0040] When the detection device 4 detects the passing of the deformed steel bar, the lifting baffle 2 rises to lift the deformed steel bar. The long-length deformed steel bar contacts the braking device 3 for braking, and the conveying roller path 1 behind the lifting baffle 2 continues to rotate, and the short-length deformed steel bars are rejected through the conveying roller path 1;
[0041] Among them, a control system can be set to be connected to the detection device 4 and the electromagnetic reversing valve of the lifting baffle 2, receive the signals sent by the detection device 4, and control the actions of the lifting baffle 2; in other embodiments, the control system can adopt control devices such as a PLC or a single-chip microcomputer to achieve automatic control:
[0042] The conveying roller path 1 conveys the deformed steel bar sheared by the cold shear through above the lifting baffle 2 until the infrared detection signal instrument detects that there is a deformed steel bar passing on the conveying roller path 1. The PLC control system transmits a signal to the electromagnetic reversing valve of the lifting baffle 2, the solenoid valve is powered on, and the lifting baffle 2 rises to lift the long-length deformed steel bar above the conveying roller path 1. The long-length deformed steel bar contacts the braking plate 31 for braking, and the conveying roller path 1 behind the lifting baffle 2 continues to rotate to transport and reject the short-length deformed steel bars falling on the roller path.
[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Those skilled in the art can make various modifications or equivalent replacements to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the technical solutions of the present invention.
