Description

Technical Field

[0002] When manufacturing a power plant boiler, it is necessary to configure a large plate beam maintenance ladder at the same time. The large plate beam maintenance ladder is generally made of round steel. The diameter of the round steel is relatively thick, generally not less than 30mm, and the number of round steel used is large. When manufacturing the large plate beam maintenance ladder, the two ends of the round steel need to be bent 90° respectively. The current bending method of round steel is to first heat the round steel with a baking gun, and then bend it manually. The above production process requires the cooperation of multiple people, with high labor intensity and low operation efficiency. In addition, due to manual operation, it is easy to have the bending angle not in place, such as the bending angle is too small, which cannot meet the production requirements of the large plate beam maintenance ladder, and secondary processing has to be carried out, which further increases the workload. In addition, the round steel is easily torn when heated with a baking gun and then bent, which causes a waste of production materials to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0021] Embodiment 1:

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the round steel bending device for a press is fixedly mounted on the pressure head assembly 1 of the press, realizes 90° bending of both ends of the round steel, and makes the bending part present an arc-shaped smooth transition, and is used for installing and configuring the large plate beam maintenance ladder of the boiler when manufacturing the power plant boiler. This embodiment includes a bending top plate 2, and a plurality of mounting screw holes 3 are arranged through the bending top plate 2. The whole device and the pressure head assembly 1 are assembled by the cooperation of the mounting screw holes 3 and the mounting bolts, so as to obtain the round steel bending power output by the pressure head assembly 1.

[0023] The bottom end of the bending top plate 2 is fixedly connected with a bending pressure plate 4 extending vertically downward, and the bottom end of the bending pressure plate 4 is fixedly connected with a bending pressure head 5. Driven by the pressure head assembly 1, the bending top plate 2, the bending pressure plate 4 and the bending pressure head 5 are moved synchronously until the bending pressure head 5 contacts the round steel to be bent. Reinforcing rib plates 6 are arranged and connected between the two sides of the bending pressure plate 4 and the bending top plate 2 to improve the strength of the bending pressure plate 4 and ensure its long-term smooth use. The lower end of each of the reinforcing rib plates 6 is respectively provided with a cut angle, and the setting of the cut angle forms an inclined surface that is gradually lowered from the outside to the inside to reduce the space occupied by the lower end of the reinforcing rib plate 6, thereby ensuring the field of vision and space for the bending operation. The bending pressure head 5 is set to be a round shaft or round rod welded and fixed on the bending pressure plate 4 to obtain the inner arc at the bending point of the round steel.

[0024] A fixedly installed bending bottom plate 7 is provided directly below the bending top plate 2, and mounting screw holes are also arranged through the bending bottom plate 7. The fixed installation of the bending bottom plate 7 is achieved through the cooperation of the mounting screw holes and the mounting bolts, so as to ensure the stability and firmness of the relevant installation components when implementing the round steel bending operation.

[0025] Two bending supports are rotatably mounted on the bending bottom plate 7, and a bending limit seat 8 is provided between the two round steel bending supports. A concave bending limit arc groove 9 is provided at the top of the bending limit seat 8. The bending pressure head 5 is arranged directly above the bending limit arc groove 9, and the end face of the bending limit arc groove 9 is in a 90° fan shape. The round steel to be bent is placed on the top of the two bending supports, and the pressure head assembly 1 is used to drive the bending top plate 2, the bending pressure plate 4 and the bending pressure head 5 downward, so that the bending pressure head 5 cooperates with the bending limit seat 8 to bend the round steel to be bent. During the bending process, the bending pressure head 5 bends the round steel and forms an inner arc at the bending position, and the bending limit arc groove 9 forms an outer arc at the bending position, and the outer arc is 90°. The bending pressure head 5 cooperates with the bending limit arc groove 9 to form an arc-shaped smooth transition at the bending position of the round steel.

[0026] A bending limit baffle 10 is provided on the outer side of one of the bending supports, and the bending limit baffle 10 is fixed on the bending bottom plate 7. When the round steel to be bent is placed on the top of the two bending supports, its end is against the bending limit baffle 10 to achieve automatic positioning of the bending position, which helps to improve the bending efficiency.

[0027] In this embodiment, the bending support member is configured as a bending support roller 11, and a bending limit ring groove 12 is provided on the bending support roller 11, and the bending limit ring grooves 12 on the two bending support rollers 11 are arranged opposite to each other. During the bending process, the round steel is always located in the bending limit ring grooves 12 on the two bending support rollers 11, and the left and right limit of the round steel is achieved by the bending limit ring grooves 12, preventing it from sliding sideways after being pressed, thereby improving the bending efficiency and bending accuracy.

[0028] Embodiment 2:

[0029] like Figure 4 As shown, the difference between this embodiment and the first embodiment is that the specific structure of the bending support member is different. In this embodiment, the bending support member is set as a bending support roller 13, and a plurality of annular bending limit roller grooves 14 are evenly distributed on the bending support roller 13, and the bending limit roller grooves 14 on the two bending support rollers 13 are respectively arranged one by one to face each other, so that multiple round steels can be bent at one time, that is, batch bending processing of round steels is realized, which greatly improves the bending efficiency.

[0030] like Figure 5 As shown, in order to facilitate the batch bending of round steel, this embodiment also includes two code steel plates 15, and round steel through holes are evenly distributed through the two code steel plates 15, and the spacing between the two adjacent round steel through holes on the same code steel plate 15 is the same as the spacing between the two adjacent bending limit roller grooves 14 on the same bending support roller 13. Before bending, the batch of round steel is first installed between the two code steel plates 15, and the code steel plates 15 are set close to the ends of the round steel to achieve the bending and stacking of the round steel, and then two people cooperate to lift the batch of round steel onto the two bending support rollers 13, and push each round steel until its end abuts against the bending limit baffle 10, and then implement the bending process; after both ends are bent, the two people can use the corresponding straps to bundle the batch of round steel and lift it down, and then separate the two code steel plates 15. In the process of round steel bending, the two code steel plates 15 also play a role in limiting and maintaining each round steel, thereby ensuring that the bending forming is qualified.

[0031] In order to facilitate the transfer of the round steel to the bending position after inserting it into the two yard steel plates 15, a carrying handle 16 is fixedly welded to the top of the yard steel plate 15, making it more convenient for two people to carry it, which helps to improve the loading efficiency when the round steel is bent.

[0032] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
