Description

Technical Field

[0001] The utility model belongs to the technical field of channel steels, and in particular relates to a channel steel bending fixture and a bending machine. Background Art

[0002] Channel steel is a long steel strip with a grooved cross-section. It is a carbon structural steel used for construction and machinery. It is a steel section with a complex cross-section. Its cross-section shape is grooved. Channel steel is mainly used in building structures, curtain wall projects, mechanical equipment and vehicle manufacturing.

[0003] However, there are some problems with the prior art: the channel steel needs to be bent into different arcs by a bending machine before use, but the existing bending machine cannot guide and limit the channel steel after bending, so that the rear side of the channel steel continues to be bent, but the front end of the channel steel after bending will swing on the top of the bending machine, which will not only reduce the safety of the operator, but also make it inconvenient to accurately bend the unbent channel steel at the rear side. Therefore, we propose a channel steel bending fixture and a bending machine. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a channel steel bending fixture and a bending machine. Through the guide component, the bent channel steel can be effectively prevented from being offset or causing harm to the operator. The bent channel steel can be tightened through the limit component to prevent the bent channel steel and the guide plate from detaching, thereby causing the channel steel to be unable to be guided.

[0005] The utility model is implemented as follows: a channel steel bending fixture comprises a placing plate, four groups of bending rollers are rotatably installed on the top of the placing plate, two groups of guide components for guiding the bent channel steel are arranged on the back of the placing plate, a limiting component for tightening the bent channel steel is arranged on the back of the placing plate, and the limiting component is located on the right side of the guiding component.

[0007] Optionally, a limit block located on the left side of the rotating rod is provided on the back side of the placement plate, and springs are fixedly installed on the front and rear sides of the right side of the limit block, and the right end of the spring is fixedly installed on the left side of the guide plate.

[0008] Optionally, an elastic rod is arranged inside the spring, the left side of the elastic rod is fixedly mounted to the right side of the limit block, and the right side of the elastic rod is fixedly mounted to the left side of the guide plate.

[0009] Optionally, the limiting assembly includes a clamping plate, a concave block is fixedly installed on the right side of the clamping plate, a connecting plate is rotatably installed inside the concave block, an electric push rod is fixedly installed on the right side of the connecting plate, and a support block is fixedly installed on the bottom of the electric push rod.

[0010] Optionally, five groups of rolling grooves are opened on the left side of the abutting plate, and rollers are rotatably mounted on the tops and bottoms of the inner walls of the five groups of rolling grooves through axle pins, and the surfaces of the rollers are in contact with the right side of the channel steel.

[0011] A bending machine also includes a bending machine body, the top of the bending machine body is fixedly connected to the top of a placing plate, a motor is fixedly installed on the left side of the bending machine body, the output end of the motor drives four groups of bending rollers to rotate through a belt, the bottom of the rotating rod is rotatably connected to the top of the bending machine body through a bearing, the top of the bending machine body is fixedly installed to the bottom of a limit block, and the bottom of the support block is fixedly installed to the top of the bending machine body.

[0012] Optionally, a stabilizing block is fixedly mounted on the bottom of the connecting plate, a stabilizing groove is provided on the top of the bending machine body, and the stabilizing block and the stabilizing groove are slidably connected.

[0013] In the present application, when the bent channel steel contacts the guide plate, and the bent channel steel is also located inside the guide groove, since the bent channel steel is arc-shaped, the guide plate will drive the rotating block and the rotating rod to rotate, so that the guide plate can adapt to channel steels with different arcs. When it is necessary to squeeze and limit the bent steel groove, the electric push rod can be started first, and the telescopic end of the electric push rod will drive the connecting plate to move to the left, and the movement of the connecting plate will drive the concave block and the abutting plate to move to the left. Since the concave block and the connecting plate are rotatably connected, the abutting plate can adapt to channel steels with different arcs, so that the bent channel steel can contact the guide plate to prevent the bent channel steel from shaking or deflecting.

DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] like Figures 1 to 4 As shown, a channel steel bending fixture provided by an embodiment of the utility model includes a placing plate 2, four groups of bending rollers 3 are rotatably installed on the top of the placing plate 2, two groups of guide components 4 for guiding the bent channel steel are arranged on the back of the placing plate 2, and a limiting component 5 for tightening the bent channel steel is arranged on the back of the placing plate 2, and the limiting component 5 is located on the right side of the guiding component 4.

[0021] Specifically, Figures 1 to 4 As shown, the channel steel to be bent is placed on the top of the placement plate 2 for bending. The bent channel steel will first be guided by the guide component 4, and then the bent channel steel will be limited by the limit component 5 to prevent the bent channel steel from detaching from the guide component 4.

[0022] Furthermore, the guide assembly 4 includes a rotating rod 401 , a rotating block 402 is fixedly installed on the top of the rotating rod 401 , a guide plate 403 is fixedly installed on the right side of the rotating block 402 , and a guide groove 404 is opened on the right side of the guide plate 403 .

[0023] Specifically, Figures 1 to 4 As shown, when the bent channel steel contacts the guide plate 403, and the bent channel steel is also located inside the guide groove 404, since the bent channel steel is arc-shaped, the guide plate 403 drives the rotating block 402 and the rotating rod 401 to rotate, so that the guide plate 403 can adapt to channel steels with different arc shapes.

[0024] Furthermore, a limit block 405 is provided on the back of the placement plate 2 and is located on the left side of the rotating rod 401. A spring 406 is fixedly installed on the front and rear sides of the right side of the limit block 405. The right end of the spring 406 is fixedly installed on the left side of the guide plate 403.

[0025] Specifically, Figures 1 to 4As shown, when encountering channel steels bent at different arcs, one side of the guide plate 403 will move to the same side at the same time, and the other side will move to the other side at the same time. When the side with greater force will compress the spring 406, and the other two groups of springs 406 will be stretched by the guide plate 403. When the channel steel is bent, the compressed spring 406 will drive the guide plate 403 to reset, and the spring 406 stretched by the guide plate 403 will shrink and reset.

[0026] Furthermore, an elastic rod 407 is provided inside the spring 406 , and the left side of the elastic rod 407 is fixedly installed to the right side of the limit block 405 , and the right side of the elastic rod 407 is fixedly installed to the left side of the guide plate 403 .

[0027] Specifically, Figures 1 to 4 As shown, when the spring 406 is compressed or stretched, the elastic rod 407 can limit the compressed or stretched spring 406 to prevent the spring 406 from being deformed during operation.

[0028] Furthermore, the limiting assembly 5 includes a clamping plate 501, a concave block 9 is fixedly installed on the right side of the clamping plate 501, a connecting plate 502 is rotatably installed inside the concave block 9, an electric push rod 503 is fixedly installed on the right side of the connecting plate 502, and a support block 504 is fixedly installed on the bottom of the electric push rod 503.

[0029] Specifically, Figures 1 to 4 As shown, when the bent steel channel needs to be squeezed and limited, the electric push rod 503 can be started first. The telescopic end of the electric push rod 503 will drive the connecting plate 502 to move to the left. The movement of the connecting plate 502 drives the concave block 9 and the clamping plate 501 to move to the left. Since the concave block 9 and the connecting plate 502 are rotatably connected, the clamping plate 501 can adapt to channel steels with different curvatures, so that the bent channel steel can contact the guide plate 403 to prevent the bent channel steel from shaking or deviating.

[0030] Furthermore, five groups of rolling grooves 505 are opened on the left side of the abutting plate 501, and rollers 506 are rotatably installed on the top and bottom of the inner walls of the five groups of rolling grooves 505 through axle pins, and the surface of the rollers 506 contacts the right side of the channel steel.

[0031] Specifically, Figures 1 to 4 As shown, when the clamping plate 501 is in contact with the bent channel steel, the roller 506 can effectively reduce the friction between the clamping plate 501 and the bent channel steel, and the bent channel steel can also be easily moved under the action of the roller 506.

[0032] A bending machine, including a bending machine body 1, the top of the bending machine body 1 and the top of the placing plate 2 are fixedly connected, a motor 6 is fixedly installed on the left side of the bending machine body 1, the output end of the motor 6 drives four sets of bending rollers 3 to rotate through a belt, the bottom of the rotating rod 401 is rotatably connected to the top of the bending machine body 1 through a bearing, the top of the bending machine body 1 and the bottom of the limit block 405 are fixedly installed, and the bottom of the support block 504 and the top of the bending machine body 1 are fixedly installed

[0033] Specifically, Figures 1 to 4 As shown, the channel steel to be bent can be placed on the top of the bending machine body 1, and the channel steel is located inside the four sets of bending rollers 3. Then the motor 6 can be started at this time, and the output shaft of the motor 6 drives the bending rollers 3 to rotate through the belt. The bending rollers 3 rotate to bend the channel steel.

[0034] Furthermore, a stabilizing block 7 is fixedly mounted on the bottom of the connecting plate 502, a stabilizing groove 8 is provided on the top of the bending machine body 1, and the stabilizing block 7 and the stabilizing groove 8 are slidably connected.

[0035] Specifically, Figures 1 to 4 As shown, the stability of the connecting plate 502 during movement can be improved, and the connecting plate 502 can be prevented from shaking during movement, thereby being unable to drive the pressing plate 501 to move in a straight line.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
