Description
Technical Field
[0001] This utility model belongs to the field of steel plate processing technology, specifically relating to a tooling for rolling angle steel. Background Technology
[0002] Angle steel is sometimes rolled into arc-shaped parts for construction purposes. The traditional manufacturing method is to use arc-shaped tooling to heat and bend the parts before straightening them.
[0003] Because of its high strength and irregular shape, angle steel is difficult to manufacture even when bent, resulting in high processing difficulty, low efficiency, high production costs, poor appearance, and difficulty in controlling dimensions, making it unsuitable for large-scale production. Three-roll plate rolling machines can only roll sheet materials such as steel plates and cannot roll angle steel, requiring additional equipment such as pipe bending machines, increasing processing costs. Furthermore, bending angle steel involves two steps, resulting in low processing efficiency. Utility Model Content

[0044] Please refer to the following: Figures 1 to 6 The present invention will now describe the angle steel rolling fixture. The angle steel rolling fixture includes a rolling machine 1, a first limiting component 2, and a second limiting component 3. The plate rolling machine 1 has one driven wheel 11 and two driving wheels. The rotation axis of the driven wheel 11 is parallel to the rotation axis of the driving wheels. The center of the driven wheel 11 is located on the line of symmetry between the centers of the two driving wheels, and the driven wheel 11 is located above the two driving wheels. The first limiting component 2 is sleeved on the outer periphery of one of the two driving wheels. The first limiting component 2 has an annular first limiting groove 25 and an annular first abutting surface 231. The first limiting groove 25 and the first abutting surface 231 are spaced apart on the axis of the corresponding driving wheel. The second limiting component 3 is sleeved on the outer periphery of the other driving wheel. The second limiting component 3 has an annular second limiting groove 34 and an annular second abutting surface 351. The second limiting groove 34 and the second abutting surface 351 are spaced apart on the axis of the corresponding driving wheel. The second abutting surface 351 and the first abutting surface 231 cooperate to abut one side of the angle steel 4, and the second limiting groove 34 and the first limiting groove 25 cooperate to insert into the other side of the angle steel 4.
[0045] It should be noted that the driven wheel 11 on the plate rolling machine 1 compresses the angle steel 4. When the two driving wheels and the driven wheel 11 rotate, the angle steel 4 will bend with the driven wheel 11 as the bending point.
[0046] It should be noted that the reference line of the wheel center is... Figure 1 The vertical dotted line in the image refers to the line of symmetry between the centers of the two driving wheels.
[0047] It should be noted that when the angle steel 4 is placed on the drive wheel, the two sides are the vertical side and the horizontal side, respectively. The bottom surface of the horizontal side abuts against the second abutting surface 351 and the first abutting surface 231, respectively, and the vertical side is inserted into the second limiting groove 34 and the first limiting groove 25.
[0048] Compared with the prior art, the angle steel rolling fixture provided in this embodiment has a first limiting component 2 and a second limiting component 3 respectively set on the two drive wheels of the rolling machine 1. The first limiting groove 25 and the second limiting groove 34 jointly limit one side of the angle steel 4, and the first abutting surface 231 and the second abutting surface 351 abut against the other side of the angle steel 4 from below, so that the angle steel 4 can be bent stably and the bending quality of the angle steel 4 can be improved. The first limiting component 2 and the second limiting component 3 can be removed without affecting the normal use of the rolling machine 1, increasing the versatility of the rolling machine 1. The first limiting component 2 and the second limiting component 3 can be used to bend the angle steel 4 by the rolling machine 1 without the need for additional mechanical equipment, reducing the cost of use. The angle steel 4 can be bent in one step, improving the processing efficiency.
[0049] In some embodiments, see Figure 3 and Figure 4 The driving wheel corresponding to the first limiting component 2 is defined as the first driving wheel 12. The first limiting component 2 includes a first limiting cylinder 21, two positioning rings 22, and an abutment ring 23. The first limiting cylinder 21 is sleeved on the outer periphery of the first driving wheel 12; the two positioning rings 22 are spaced apart along the axis of the first driving wheel 12 on the outer periphery of the first limiting cylinder 21, and the two positioning rings 22 enclose each other to form a first limiting groove 25; the abutment ring 23 is sleeved on the outer periphery of the first driving wheel 12 and is located between the positioning rings 22 and the plate rolling machine 1, the outer peripheral surface of the abutment ring 23 forms a first abutment surface 231, and the abutment ring 23 and the nearest positioning ring 22 form an insertion groove 24.
[0050] It should be noted that the outer diameter of the abutment ring 23 is larger than the outer diameter of the positioning ring 22, ensuring that the first abutment surface 231 and the groove wall of the first limiting groove 25 are perpendicular to each other.
[0051] This embodiment provides one implementation of the first limiting component 2. A first limiting cylinder 21 is fitted onto the first driving wheel 12 and rotates synchronously with it. Two positioning rings 22 and an abutment ring 23 are provided on the first limiting cylinder 21. The two positioning rings 22 form a gap in the first limiting groove 25. When the first limiting cylinder 21 rotates with the first driving wheel 12, the first limiting groove 25 is always inserted into one side of the angle steel 4, preventing this side from bending when the angle steel 4 is bent, thus ensuring the bending effect of the angle steel 4. The side of the abutment ring 23 abuts against the other side of the angle steel 4, allowing this side to be bent normally by the driven wheel 11. The positioning rings 22 and the abutment ring 23 are easy to manufacture, easily achieving the bending of the angle steel 4, saving manufacturing costs. The first limiting cylinder 21 is detachable and does not affect the other functions of the plate rolling machine 1.
[0052] As another embodiment of the first limiting component 2, the second limiting component 2 includes three limiting cylinders, which are sequentially sleeved on the first drive wheel 12, and the ends of two adjacent limiting cylinders are welded together. Each limiting cylinder is provided with a forming ring. A first limiting groove 25 is formed between the two forming rings away from the main body of the plate rolling machine 2, and a first abutting surface 231 is formed on the outer circumferential surface of the forming ring close to the main body of the plate rolling machine 2, and the outer diameter of this forming ring is larger than the outer diameter of the other two forming rings.
[0053] In some embodiments, see Figure 3 and Figure 4 The first limiting cylinder 21 has a tightening hole 213 extending radially through its outer periphery, and a set screw is provided in the tightening hole 213. The set screw can tighten the first limiting cylinder 21 onto the first driving wheel 12, thereby improving the synchronization between the first limiting cylinder 21 and the first driving wheel 12.
[0054] In some embodiments, see Figure 3 and Figure 4 The first limiting cylinder 21 includes two mutually abutting first arc-shaped plates 211, which are symmetrically arranged about the axis of the first driving wheel 12. One of the first arc-shaped plates 211 has fixing holes at both ends, and the other has connecting holes at both ends corresponding to the fixing holes. The two arc-shaped plates 211 are fixedly connected by a first fastener 212 passing through the fixing holes and connecting holes. The abutting ring 23 includes two mutually abutting arc-shaped plates, which are respectively located on the outer periphery of the corresponding first arc-shaped plate 211. The positioning ring 22 includes two mutually abutting positioning arc-shaped plates, which are respectively located on the outer periphery of the corresponding first arc-shaped plate 211. The two first arc-shaped plates 211 are detachably installed on the outer periphery of the first driving wheel 12 by the first fastener 212, increasing the ease of installation and removal of the first limiting cylinder 21. Installing the first arc-shaped plates 211 from both sides of the first driving wheel 12 is less difficult, reducing the difficulty of installation and removal.
[0055] Specifically, the first fastener 212 is a nut with a bolt. After the bolt passes through the fixing hole and the connecting hole, it is screwed into the nut to clamp the two first arc-shaped plates 211.
[0056] In some embodiments, see Figure 3 The width of the insertion groove 24 is greater than the width of the first limiting groove 25. The width of the first limiting groove 24 is equal to the thickness of the side of the angle steel 4. The fact that the width of the insertion groove 24 is greater than the width of the first limiting groove 25 facilitates the subsequent use of the insertion groove.
[0057] In some embodiments, see Figure 5 and Figure 6 The driving wheel corresponding to the second limiting component 3 is defined as the second driving wheel 13. The second limiting component 3 includes a second limiting cylinder 31, a limiting ring 32, and a mating ring 33. The second limiting cylinder 31 is sleeved on the outer periphery of the second driving wheel 13; the limiting ring 32 is sleeved on the outer periphery of the second limiting cylinder 31; the mating ring 33 is sleeved on the outer periphery of the second limiting cylinder 31 and is spaced apart from the limiting ring 32 on the axis of the second driving wheel 13. A second limiting groove 34 is formed between the mating ring 33 and the limiting ring 32. The end of the mating ring 33 away from the limiting ring 32 is also provided with an annular abutment protrusion 35. The outer peripheral surface of the abutment protrusion 35 forms a second abutment surface 351. The abutment protrusion 35 is inserted into the insertion groove 24.
[0058] In specific implementation, the outer periphery of the second limiting cylinder 31 is also provided with a set screw hole, and a set screw is provided in the set screw hole to ensure that the second limiting cylinder 31 and the second driving wheel 13 rotate synchronously and improve the connection strength.
[0059] This embodiment provides a specific structure for the second limiting component 3. A second limiting groove 34 is formed by the limiting ring 32 and the mating ring 33, improving the spatial stability of the second limiting groove 34. This ensures that the angle steel 4 can be stably bent during bending. The outer circumferential surface of the abutment protrusion 35 forms a second abutment surface 351, stably supporting the other side of the angle steel 4 and ensuring that the two sides of the angle steel 4 are always perpendicular to each other, thus ensuring bending quality. The abutment protrusion 35 also engages with the insertion groove 24, minimizing the distance between the first driving wheel 12 and the second driving wheel 13. The engagement of the abutment protrusion 35 and the insertion groove 24 ensures that the first limiting cylinder 21 and the second limiting cylinder 31 mutually limit each other along the axial direction of the driving wheel, thereby ensuring that the first limiting groove 25 and the second limiting groove 34 are always in the same vertical plane, guaranteeing the forming quality of the angle steel 4.
[0060] As another embodiment of the second limiting component 3, the second limiting component 3 includes three sleeves, which are sequentially sleeved on the second drive wheel 13, and adjacent two sleeves are welded together. Abutment rings are respectively provided on the two sleeves away from the main body of the plate rolling machine 2, and a second limiting groove 34 is formed between the two abutment rings. A contact ring is also connected to the outer periphery of the abutment ring close to the main body of the plate rolling machine 2, and the outer periphery of the contact ring forms a second abutment surface 351.
[0061] In some embodiments, see Figure 5 and Figure 6 The second limiting cylinder 31 includes two mutually abutting second arc-shaped plates 311, which are symmetrically arranged about the axis of the second driving wheel 13. One of the second arc-shaped plates 311 has mounting holes at both ends, and the other second arc-shaped plate 311 has positioning holes at both ends corresponding to the mounting holes. The two second arc-shaped plates 311 are fixedly connected by a second fastener 312 that passes through the mounting holes and positioning holes. The limiting ring 32 includes two mutually abutting limiting arc plates, which are respectively located on the outer periphery of the corresponding second arc-shaped plates 311. The mating ring 33 includes two mutually abutting mating arc plates, which are respectively located on the outer periphery of the corresponding second arc-shaped plates 311. The two second arc-shaped plates 311 are detachably connected by the second fasteners 312, and the second limiting cylinders 31 can be connected from both sides of the second driving wheel 13. After the two second arc-shaped plates 311 are connected, the second limiting cylinders 31 are fixedly abutted against the second driving wheel 13, so that the second driving wheel 13 drives the second limiting cylinders 31 to rotate, ensuring that the second limiting groove 34 is stably inserted into the angle steel 4 when rotating, and improving the bending stability of the angle steel 4.
[0062] It should be noted that the outer diameter of the abutting protrusion 35 is equal to the outer diameter of the abutting ring 23, so as to stabilize the abutting of the horizontal side of the angle steel 4.
[0063] In some embodiments, see Figure 2 A gap is provided between the outer periphery of the abutting protrusion 35 and the insertion groove 24, and the thickness of the abutting protrusion 35 is greater than the thickness of the second limiting groove 34. In order to increase the contact area with the angle steel 4, the thickness of the abutting protrusion 3535 is greater than the thickness of the second limiting groove 34, so that the second abutting surface 351 is stably abutted against the other side of the angle steel 4.
[0064] In some embodiments, the driven wheel 11 is a lifting wheel, which can move up and down in the vertical direction. The up and down movement of the driven wheel 11 facilitates the insertion of the angle steel 4 and improves ease of use.
[0065] In practice, the driven wheel 11 is connected to the plate rolling machine 1 via a connecting shaft. The connecting shaft can move up and down and is hinged to the driven wheel 11.
[0066] In some embodiments, heat dissipation holes are provided on the first arc plate 211 and the second arc plate 311 along the thickness direction, respectively.
[0067] In some embodiments, see Figure 2 The width of the first limiting groove 25 is equal to the width of the second limiting groove 34. The first limiting groove 25 and the second limiting groove 34 cooperate to insert and limit the side of the angle steel 4. The equal width of the first limiting groove 25 and the second limiting groove 34 can ensure that the side of the angle steel 4 will not move in the vertical direction after entering the second limiting groove 34 from the first limiting groove 25, thereby improving the bending quality of the angle steel 4.
[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
