Description

Technical Field

[0001] The utility model relates to the technical field of straightening machines, in particular to a straightening machine with a protection mechanism. Background Art

[0002] Section steel is a bar-shaped steel with a certain cross-sectional shape and size. According to the cross-sectional shape, section steel is divided into simple-section section steel and complex-section section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, bent steel, etc. Among them, round steel refers to a solid long bar steel with a circular cross-section. When the diameter of the round steel is small, it is extremely easy to bend. Therefore, a straightening machine is needed to straighten the round steel.

[0003] The existing round steel straightening machines often directly put the bent round steel to be straightened into the straightening equipment for straightening. However, when there is dirt and a large amount of dust on the surface of the round steel, it is easy to bring the dirt and dust into the inside of the round steel straightening machine and remain on the surface of the straightening rollers. This is not only inconvenient for cleaning, but also easy to affect the straightening effect. In view of this, we propose a straightening machine with a protection mechanism. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a straightening machine with a protection mechanism to solve the technical problem that the existing round steel straightening machines often directly put the bent round steel to be straightened into the straightening equipment for straightening. However, when there is dirt and a large amount of dust on the surface of the round steel, it is easy to bring the dirt and dust into the inside of the round steel straightening machine and remain on the surface of the straightening rollers. This is not only inconvenient for cleaning, but also easy to affect the straightening effect.

[0005] To achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a straightening machine with a protection mechanism, including a straightening machine body. A positioning frame is arranged on the right side surface of the straightening machine body, and the straightening machine body and the positioning frame are connected by bolts. A decontamination component is arranged in the middle of the positioning frame, and a limiting mechanism is arranged inside the decontamination component;

[0006] The decontamination component includes a blower. The blower is arranged on the outer surface of the positioning frame, and the blower and the positioning frame are connected by screws. An air duct is fixedly clamped inside the positioning frame, and one end of the air duct away from the positioning frame is connected with a limiting frame.

[0007] Preferably, the blower is communicated with the limiting frame through the air duct, and the inner diameter of the middle part of the limiting frame is larger than the inner diameter of the side.

[0008] Preferably, the limiting mechanism includes a first arc plate, a set of connecting rods are connected to the rear end of the first arc plate, a second arc plate is connected to the rear end of the connecting rods, a movable rod is connected to the middle parts of the outer sides of the first arc plate and the second arc plate, a spring is connected to one side of the movable rod, and a fixed groove frame is sleeved outside the spring.

[0009] Preferably, a set of the movable rods are fixedly connected to the first arc plate and the second arc plate respectively, and the movable rods are in a T shape.

[0010] Preferably, the large-diameter end of the movable rod is clamped inside the fixed groove frame, the fixed groove frame is fixedly connected to the limiting frame, and the movable rod and the fixed groove frame form an elastic structure through the spring.

[0011] Preferably, three of the limiting mechanisms are evenly distributed in a ring shape.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The present utility model limits the round steel through the limiting mechanism, and then turns on the blower, effectively transmitting the flowing air to the limiting frame through the air duct. Since the inside of the limiting frame is in a groove shape, it is convenient for the flowing air to stay fully inside the limiting frame, and the high-speed flowing air effectively impacts the surface of the round steel, removing the dirt and dust on the surface of the round steel, preventing the dirt and dust on the surface of the round steel from entering the inside of the straightening machine body, reducing the pollution and damage to the straightening rollers, and improving the protection of the straightening rollers.

[0014] 2. In the present utility model, since the movable rod and the fixed groove frame form an elastic structure through the spring, the positions of the first arc plate and the second arc plate are adjustable, which is convenient for adapting to and limiting round steel with different diameters, improving the applicability of the device. The three limiting mechanisms evenly distributed in a ring shape can effectively center and limit the round steel, making the round steel coincide with the center of the inlet of the straightening machine body, and facilitating the round steel to directly enter the inside of the straightening rollers of the straightening machine body subsequently.

[0022] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0023] A straightening machine with a protection mechanism, see Figures 1 to 4 , including a straightening machine body 1. A positioning frame 2 is provided on the right side surface of the straightening machine body 1. The straightening machine body 1 and the positioning frame 2 are connected by bolts 3. A dirt removal assembly 4 is provided in the middle of the positioning frame 2, and a limiting mechanism 5 is provided inside the dirt removal assembly 4;

[0024] The dirt removal assembly 4 includes a blower 401 which is arranged on the outer surface of the positioning frame 2. The blower 401 and the positioning frame 2 are connected by screws 402. An air duct 403 is fixedly clamped inside the positioning frame 2. One end of the air duct 403 far from the positioning frame 2 is connected with a limiting frame 404. Among them, the blower 401 is communicated with the limiting frame 404 through the air duct 403, and the inner diameter of the middle part of the limiting frame 404 is larger than the inner diameter of the side. The present utility model limits the round steel through the limiting mechanism 5, and then starts the blower 401, effectively transmitting the flowing air to the limiting frame 404 through the air duct 403. Since the inside of the limiting frame 404 is in a groove shape, it is convenient for the flowing air to stay fully inside the limiting frame 404. The high-speed flowing air effectively impacts the surface of the round steel, removing the dirt and dust on the surface of the round steel, preventing the dirt and dust on the surface of the round steel from entering the inside of the straightening machine body 1, reducing the pollution and damage to the straightening rollers, and improving the protection of the straightening rollers.

[0025] It should be noted that the limiting mechanism 5 includes an arc plate 501. A group of connecting rods 502 are connected to the rear end of the arc plate 501. The rear end of the connecting rod 502 is connected to an arc plate 503. A movable rod 504 is connected to the middle part of the outer sides of the arc plate 501 and the arc plate 503. Further, a group of movable rods 504 are respectively fixedly connected to the arc plate 501 and the arc plate 503. The movable rod 504 is in a T shape. A spring 505 is connected to one side of the movable rod 504. A fixed groove frame 506 is sleeved outside the spring 505. Still further, the large-diameter end of the movable rod 504 is engaged inside the fixed groove frame 506. The fixed groove frame 506 is fixedly connected to the limiting frame 404. The movable rod 504 and the fixed groove frame 506 form an elastic structure through the spring 505. Among them, three limiting mechanisms 5 are evenly distributed in a ring shape. In the present utility model, since the movable rod 504 and the fixed groove frame 506 form an elastic structure through the spring 505, the positions of the arc plate 501 and the arc plate 503 are adjustable, which is convenient for adapting and limiting round steel with different diameters, improving the applicability of the device. The three limiting mechanisms 5 evenly distributed in a ring shape can effectively center and limit the round steel, making the round steel coincide with the center of the inlet of the straightening machine body 1, and facilitating the subsequent direct entry of the round steel into the inside of the straightening rollers of the straightening machine body 1.

[0026] Working principle: The operator first puts one end of the round steel into the limiting mechanism 5. Since the movable rod 504 and the fixed groove frame 506 form an elastic structure through the spring 505, the positions of the arc plate 501 and the arc plate 503 are adjustable, which is convenient for adapting and limiting round steel with different diameters. Then, the blower 401 is turned on, and the flowing air is transmitted to the limiting frame 404 through the air duct 403. Since the inside of the limiting frame 404 is in a groove shape, it is convenient for the flowing air to stay fully inside the limiting frame 404. The high-speed flowing air impacts the surface of the round steel to remove the dirt and dust on the surface of the round steel, preventing the dirt and dust on the surface of the round steel from entering the inside of the straightening machine body 1 and reducing the pollution and damage to the straightening rollers. The operator slowly sends the round steel into the inside of the straightening machine body 1 until the round steel contacts the straightening rollers. Subsequently, the round steel can be continuously transmitted by the driving component inside the straightening machine body 1 to realize the continuous straightening of the round steel.

Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
