Description

Technical Field

[0001] This utility model belongs to the field of steel processing, and relates to round steel bending and forming, and more particularly to a round steel bending and forming machine. Background Technology

[0002] Traditional round steel bending involves welding rollers onto a work platform and then performing the process manually with hammers. This method is inefficient, time-consuming, and labor-intensive, with the following specific drawbacks: 1. Low efficiency and high scrap rate. 2. The final shape of the workpiece is completed manually. Therefore, to improve the efficiency of round steel bending, there is an urgent need for equipment that can replace manual labor in this process. Utility Model Content

[0003] This utility model addresses the above-mentioned problems by providing a round steel bending and forming machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a round steel bending and forming machine, comprising a fixed frame, an upper driving mechanism, and a lower mold mechanism. The driving mechanism includes a cylinder seat, on which a driving cylinder is connected. A cylinder guide seat is slidably connected below the cylinder seat. A driving rod is rotatably connected below the cylinder guide seat. A roller is rotatably connected to one end of the driving rod away from the cylinder guide seat. The mold mechanism includes a vertical first template. Several support rods are fixedly connected to the side of the first template away from the fixed frame. A second template is fixedly connected to one end of the support rod away from the first template. Both the first template and the second template are provided with tracks corresponding to the rollers. The rollers are slidably connected to the tracks. A mold is provided on the support rod.

[0005] Preferably, the cylinder guide seat includes two slide rods that pass through the cylinder seat in a vertical direction.

[0006] Preferably, the roller has a groove on its side, the mold is a circular thin plate, and the track is arc-shaped.

[0007] Preferably, a guide post is connected to the side of the first template close to the second template, and one end of the guide post passes through the mold and is connected to a baffle.

[0008] Preferably, a demolding cylinder is connected to the side of the first template away from the second template, and one end of the demolding cylinder passes through the center of the mold connected to the first template.

[0009] Preferably, the first template is connected to two positioning blocks, which are distributed on both sides of the top of the mold, and the positioning blocks are provided with right-angle grooves.

[0010] Preferably, the roller is provided with a rotating shaft on both sides, and the rotating shaft passes through the track.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention uses a cylinder to drive rollers to move along a track, bending round steel placed between the rollers and the mold into shape. This saves workers' operating time and results in a high pass rate for bending.

[0013] This utility model is equipped with a demolding cylinder to drive the mold to move, and the roller is provided with a groove. The round steel passes through the groove, so the round steel between the roller and the mold will not move with the mold. After the mold moves, the round steel is separated from the mold, making it convenient for workers to remove the bent round steel. Attached Figure Description

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, in order to replace manual bending and shaping of round steel 5, this utility model provides a round steel 5 bending and forming machine, including a fixed frame 1, an upper driving mechanism 2 and a lower mold mechanism 3. The fixed frame 1 supports the driving mechanism 2 and the mold mechanism 3. The driving mechanism 2 includes a cylinder seat 21, a driving cylinder 22 connected to the cylinder seat 21, a cylinder guide seat 23 slidably connected below the cylinder seat 21, a driving rod 24 rotatably connected below the cylinder guide seat 23, and a roller 25 rotatably connected to the end of the driving rod 24 away from the cylinder guide seat 23. The mold mechanism 3 includes a vertical first template 31, a plurality of support rods 32 fixedly connected to the side of the first template 31 away from the fixed frame 1, and a second template 33 fixedly connected to the end of the support rods 32 away from the first template 31. The first template 31 and the second template 33 are both provided with rails 34 corresponding to the rollers 25. The rollers 25 are slidably connected to the rails 34. A mold 35 is provided on the support rods 32, and the mold 35 is located directly below the rollers 25 that have not been lowered.

[0022] The working principle of this utility model is as follows: a round steel bar 5 is placed on the mold 35, a roller 25 presses on the round steel bar 5, and a drive cylinder 22 pushes the roller 25 to move along the track 34, while bending and deforming the round steel bar 5.

[0023] Furthermore, the cylinder guide seat 23 includes two slide rods that pass through the cylinder seat 21 in a vertical direction.

[0024] The final shaping of the round steel bar 5 is related to the shape of the track 34, the shape of the mold 35, and their relative positions. In order to bend the round steel bar 5 into a near-circular shape, this utility model is further configured as follows:

[0025] Furthermore, the roller 25 has an annular groove on its side, through which the round steel 5 passes. The mold 35 is a circular thin plate, through which the round steel 5 passes between the side of the roller 25 and the side of the mold 35. In order to cooperate with the circular mold 35, the track 34 is arc-shaped. At least two rollers 25 are provided, which move along the two sides of the mold 35 respectively, so that the round steel 5 is subjected to balanced force on both sides when bending. Therefore, the roller 25 can bend the round steel 5 into a shape close to a ring by moving along the arc-shaped track 34.

[0026] Furthermore, a guide post 36 is connected to the side of the first template 31 near the second template 33. One end of the guide post 36 passes through the mold 35 and is connected to a baffle 37. The baffle 37 cannot pass through the mold 35.

[0027] Furthermore, a demolding cylinder 6 is connected to the side of the first template 31 away from the second template 33, and one end of the demolding cylinder 6 passes through the center of the first template 31 and the mold 35.

[0028] Specifically, after the round steel bar 5 is bent and formed, the round steel bar 5 is wrapped around the outside of the mold 35. The demolding cylinder 6 is activated, and the demolding cylinder 6 pulls the mold 35 to move towards the first template 31. Because the round steel bar 5 passes through the groove, the round steel bar 5 will not move with the mold 35. The round steel bar 5 is removed from the mold 35. Then, the cylinder guide seat 23 is manually lifted to remove the round steel bar 5 hanging on the support rod 32. Subsequently, the demolding cylinder 6 pushes the mold 35 closer to the second template 33 until it is blocked by the baffle 37. At this time, the mold 35 is directly below the roller 25 that has not been lowered, or in other words, the side of the mold 35 is aligned with the groove of the roller 25.

[0029] Furthermore, the first template 31 is connected to two positioning blocks 4, which are distributed on both sides of the top of the mold 35. The positioning blocks 4 are provided with right-angle grooves 41.

[0030] Specifically, since the straight round steel bar 5 needs to pass between the roller 25 and the side of the mold 35, when placing the round steel bar 5, it is placed on top of the mold 35 so that after the raised roller 25 falls, the round steel bar 5 needs to enter the groove. However, without a reference point, it is difficult to align the placed round steel bar 5 with the groove, and careful adjustment is required to succeed. Therefore, a positioning block 4 is provided on the first template 31, and the positioning block 4 is further provided with a right-angle groove 41. When placing the round steel bar 5, it is made to pass through the right-angle groove 41 and pressed against the right angle of the right-angle groove 41, so that the round steel bar 5 is positioned and can accurately enter the groove after the roller 25 falls.

[0031] Furthermore, the roller 25 is provided with a rotating shaft 26 on both sides, which passes through the track 34, enabling the roller 25 to move along the track 34. The roller 25 is rotatably connected to the drive rod 24 through the rotating shaft 26.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
