Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a steel plate double bending device. Background Technology

[0002] Given a certain component, such as Figure 1 As shown, the component 100 has a first segment 110, a second segment 120, and a third segment 130 that are fixedly connected in sequence. The first segment 110 and the third segment 130 are parallel to each other, and the first segment 110 and the third segment 130 have the same included angle α with the second segment 120. When processing this component using an existing bending device (such as a steel plate hydraulic bending device disclosed in application number 202221523853.X), the connection between the first and second segments of the long strip steel plate is first placed in a mold, and the punch head punches and bends the connection between the first and second segments. After the first bending process, the second and third segments of the long strip steel plate are bent to one side at a certain angle. Then, the connection between the second and third segments of the long strip steel plate is placed in a mold again, and the punch head punches and bends the connection between the second and third segments. After the second bending process, the third segment of the long strip steel plate is bent to the opposite side at a certain angle. Throughout the bending process, workers need to hold the other end of the long steel plate, which can easily cause injury to their personal safety. In addition, after the first bending process is completed, workers take out the steel plate and readjust the bending position, which also reduces processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a two-stage bending device for steel plates. This device solves the technical problems in the prior art where workers hold long strip steel plates during the bending process, which can easily cause injury to their personal safety, and where workers remove the steel plates and readjust the bending position after the first bending process, which reduces processing efficiency.

[0004] To achieve the above technical objectives, the present invention provides a steel plate double-bending device, comprising:

[0005] The platform has a bearing surface for supporting the first section of the steel plate, and suspends the second and third sections of the steel plate in the air;

[0006] A clamping mechanism having a clamping end arranged toward the bearing surface for clamping a first section of the steel plate;

[0007] The first bending mechanism includes a first bending member and a first driving component. The first driving component is connected to the first bending member and is used to drive the first bending member to move toward the second section of the steel plate so that the second and third sections of the steel plate are bent at a preset angle.

[0008] The second bending mechanism includes a second bending member and a second driving assembly. The second driving assembly is connected to the second bending member and is used to drive the second bending member to move toward the third section of the steel plate so that the third section of the steel plate bends at a preset angle.

[0009] Furthermore, the bearing surface includes a first plane, a first arc surface, and a first inclined surface connected in sequence. The first plane is used to bear the first section of the steel plate, and the first inclined surface is used to bear the second section of the steel plate after the first bend.

[0010] Furthermore, the length of the first inclined plane is less than the length of the second segment of the steel plate.

[0011] Furthermore, the clamping mechanism includes a clamping seat and a first telescopic drive member. The clamping seat forms the clamping end, and the output end of the first telescopic drive member is fixedly connected to the clamping seat for driving the clamping seat to move up and down so that the clamping seat clamps or releases the first section of the steel plate.

[0012] Furthermore, the first bending component includes a bending roller, which is horizontally arranged. The arc-shaped wall of the bending roller is used to slide against the top surface of the second section of the steel plate. The first driving component is connected to one end of the bending roller and is used to drive the bending roller to reciprocate around the first arc surface so that the second section of the steel plate abuts against the first inclined surface.

[0013] Furthermore, the first driving component includes a turntable and a rotation driving component. The turntable is concentrically arranged with the first arc surface, and the turntable is fixedly connected to one end of the bending roller. The output end of the rotation driving component is coaxially arranged with the turntable and is used to drive the turntable to reciprocate around its center.

[0014] Furthermore, the second bending component includes a bending seat, and the second driving assembly includes a second telescopic driving component. The output end of the second telescopic driving component is fixedly connected to the bending seat and is used to drive the bending seat to move horizontally so that the bending seat approaches or moves away from the third segment of the steel plate after the first bend. During the process of the bending seat approaching the third segment of the steel plate, its top slides against the bottom surface of the third segment of the steel plate and pushes the third segment of the steel plate to bend upward into a horizontal state.

[0015] Furthermore, the top of the bending seat is located on the same horizontal plane as the connection between the second and third sections of the steel plate.

[0016] Furthermore, the steel plate double bending device also includes a positioning mechanism, which is disposed on the side of the platform and is used to abut against the connection between the second and third sections of the steel plate after the first bending.

[0017] Furthermore, the positioning mechanism includes a positioning seat and a third telescopic drive member. The bottom of the positioning seat has a second plane, a second arc surface and a second inclined surface connected in sequence. The second plane is used to abut against the third section of the steel plate after the second bend. The output end of the third telescopic drive member is fixedly connected to the positioning seat and is used to drive the positioning seat to move up and down so that the second inclined surface abuts against the top surface of the second section of the steel plate after the first bend.

[0018] Compared with the prior art, the beneficial effects of this utility model include: when bending the steel plate, the steel plate is first placed on the bearing surface of the platform, ensuring that the second and third sections of the steel plate are suspended. Then, the first section of the steel plate is pressed by the pressing end of the pressing mechanism, thereby positioning the steel plate and preventing it from moving during the bending process. By controlling the first driving component, the first driving component can drive the first bending component to move towards the second section of the steel plate, thereby bending the second and third sections of the steel plate at a preset angle. Then, by controlling the second driving component, the second driving component can drive the second bending component to move towards the third section of the steel plate, thereby bending the third section of the steel plate at a preset angle. After the above two bending processes, the steel plate forms a component. When processing this component using this two-stage bending device, the worker no longer needs to hold the other end of the long strip steel plate during the entire bending process, ensuring the worker's personal safety. Furthermore, after the first bending process is completed, the steel plate can be directly bent in the second bending process, saving the time for the worker to remove the steel plate and readjust the bending position, thus improving processing efficiency.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] This utility model provides a steel plate double-bending device, the structure of which is as follows: Figure 2 - Figure 5 As shown, the system includes a platform 200, a clamping mechanism 300, a first bending mechanism 400, and a second bending mechanism 500. The platform 200 has a bearing surface 210 for bearing a first section 110 of a steel plate and suspending a second section 120 and a third section 130 of the steel plate. The clamping mechanism 300 has a clamping end arranged toward the bearing surface 210 for clamping the first section 110 of the steel plate. The first bending mechanism 400 includes a first bending member 410 and a first driving assembly 420. The second bending mechanism 500 is connected to the first bending member 410 and is used to drive the first bending member 410 to move toward the second segment 120 of the steel plate, so that the second segment 120 and the third segment 130 of the steel plate are bent at a preset angle; the second bending mechanism 500 includes a second bending member 510 and a second driving assembly 520, the second driving assembly 520 is connected to the second bending member 510 and is used to drive the second bending member 510 to move toward the third segment 130 of the steel plate, so that the third segment 130 of the steel plate is bent at a preset angle.

[0027] When bending the steel plate, the steel plate is first placed on the bearing surface 210 of the platform 200, ensuring that the second section 120 and the third section 130 of the steel plate are suspended. Then, the first section 110 of the steel plate is pressed by the pressing end of the pressing mechanism 300, thereby positioning the steel plate and preventing it from moving during the bending process. By controlling the first driving component 420, the first driving component 420 can drive the first bending component 410 to move towards the second section 120 of the steel plate, thereby bending the second section 120 and the third section 130 of the steel plate at a preset angle. The second driving component 520 can drive the second bending member 510 to move toward the third segment 130 of the steel plate, thereby bending the third segment 130 of the steel plate at a preset angle. After the above two bends, the steel plate forms a component. When processing the component using this steel plate two-bending device, the worker no longer needs to hold the other end of the long strip steel plate during the entire bending process, ensuring the worker's personal safety. Furthermore, after the first bending process is completed, the steel plate can be directly subjected to the second bending process, saving the time for the worker to remove the steel plate and readjust the bending position, thus improving processing efficiency.

[0028] As a preferred embodiment, please refer to Figure 2 and Figure 3 The bearing surface 210 includes a first plane 211, a first arc surface 212, and a first inclined surface 213 connected in sequence. The first plane 211 is used to support the first section 110 of the steel plate, and the first inclined surface 213 is used to support the second section 120 of the steel plate after the first bend. Thus, the bending angle of the first bending process can be determined by the first arc surface 212 and the first inclined surface 213. After the first bending process, the first inclined surface 213 abuts against the second section 120 of the component 100, ensuring that after the first bending process, an included angle α can be formed between the second section 120 and the first section 110 of the component 100.

[0029] As a preferred embodiment, please refer to Figure 3 The length of the first inclined surface 213 is less than the length of the second section 120 of the steel plate, which facilitates the second bending mechanism 500 to bend the third section 130 of the steel plate upward.

[0030] As a preferred embodiment, please refer to Figure 3 and Figure 4The clamping mechanism 300 includes a clamping seat 310 and a first telescopic drive member 320. The clamping seat 310 forms the clamping end. The output end of the first telescopic drive member 320 is fixedly connected to the clamping seat 310 and is used to drive the clamping seat 310 to move up and down so that the clamping seat 310 clamps or releases the first section 110 of the steel plate. When the first telescopic drive member 320 is activated, the output end of the first telescopic drive member 320 extends, thereby driving the clamping seat 310 to move downward until the bottom of the clamping seat 310 clamps the first section 110 of the steel plate, thereby positioning the steel plate and preventing the steel plate from moving during bending.

[0031] As a preferred embodiment, please refer to Figure 4 and Figure 5 The first bending component 410 includes a bending roller 411, which is horizontally arranged. The arc-shaped wall of the bending roller 411 is used to slide against the top surface of the second section 120 of the steel plate. The first driving component 420 is connected to one end of the bending roller 411 and is used to drive the bending roller 411 to reciprocate around the first arc surface so that the second section 120 of the steel plate abuts against the first inclined surface. By operating the first driving component 420, the first driving component 420 can drive the bending roller 411 to rotate forward around the first arc surface 212. During the forward rotation of the bending roller 411 around the first arc surface 212, the second section 120 and the third section 130 of the steel plate can be bent downward until the second section 120 of the steel plate abuts against the first inclined surface 213. After the first bending process, an included angle α can be formed between the second section 120 and the first section 110 of the steel plate.

[0032] As a preferred embodiment, please refer to Figure 3 and Figure 4 The distance between the bending roller 411 and the platform 200 is equal to the thickness of the steel plate, so that the bending roller 411 can maintain sliding contact with the second section 120 of the steel plate.

[0033] As a preferred embodiment, please refer to Figure 4 and Figure 5 The first driving component 420 includes a turntable 421 and a rotation driving component. The turntable 421 is concentrically arranged with the first arc surface 212, and one end of the turntable 421 is fixedly connected to the bending roller 411. The output end of the rotation driving component is coaxially arranged with the turntable 421 and is used to drive the turntable 421 to reciprocate around its center. When the rotation driving component is activated, the output end of the rotation driving component rotates in the forward or reverse direction, causing the turntable 421 to rotate around the center of the first arc surface 212, thereby driving the bending roller 411 to rotate in the forward or reverse direction around the first arc surface 212.

[0034] As a preferred embodiment, please refer to Figure 3 and Figure 4 The second bending member 510 includes a bending seat 511, and the second driving assembly 520 includes a second telescopic driving member 521. The output end of the second telescopic driving member 521 is fixedly connected to the bending seat 511 and is used to drive the bending seat 511 to move horizontally, so that the bending seat 511 approaches or moves away from the third segment 130 of the steel plate after the first bend. During the process of the bending seat 511 approaching the third segment 130 of the steel plate, its top surface slides against the bottom surface of the third segment 130 of the steel plate. The third section 130 of the steel plate is pushed upward to bend into a horizontal state. After the first bending process is completed, the second telescopic drive 521 is activated. The output end of the second telescopic drive 521 extends, driving the bending seat 511 to move in the horizontal plane and gradually approach the third section 130 of the steel plate. During the process of the bending seat 511 approaching the third section 130 of the steel plate, its top slides and abuts against the bottom surface of the third section 130 of the steel plate, thereby pushing the third section 130 of the steel plate upward to bend into a horizontal state.

[0035] As a preferred embodiment, please refer to Figure 4 and Figure 5 The top of the bending seat 511 is located on the same horizontal plane as the connection between the second section 120 and the third section 130 of the steel plate, so that the top of the bending seat 511 can push the third section 130 of the steel plate to bend upward into a horizontal state.

[0036] As a preferred embodiment, please refer to Figure 4 and Figure 5 The steel plate double bending device further includes a positioning mechanism 600, which is disposed on the side of the platform 200 and is used to abut against the connection between the second section 120 and the third section 130 of the steel plate after the first bending. Thus, the connection between the second section 120 and the third section 130 of the steel plate after the first bending can be determined by the positioning mechanism 600. After the second bending process, the second section 120 and the first section 110 of the component 100 can form an included angle α, thereby improving the bending effect of the second bending process.

[0037] As a preferred embodiment, please refer to Figure 4 and Figure 5The positioning mechanism 600 includes a positioning seat 610 and a third telescopic drive member 620. The bottom of the positioning seat 610 has a second plane 611, a second arc surface 612, and a second inclined surface 613 connected in sequence. The second plane 611 is used to abut against the third segment 130 of the steel plate after the second bend. The output end of the third telescopic drive member 620 is fixedly connected to the positioning seat 610 and is used to drive the positioning seat 610 to move up and down so that the second inclined surface 613 abuts against the top surface of the second segment 120 of the steel plate after the first bend. Thus, the bending angle of the second bending process can be determined by the second arc surface 612 and the second inclined surface 613. After the second bending process, the second plane 611 abuts against the third segment 130 of the component 100, ensuring that an included angle α can be formed between the third segment 130 and the second segment 120 of the component 100 after the second bending process.

[0038] As a preferred embodiment, please refer to Figure 2 and Figure 3 The steel plate double bending device further includes a base 700, on which a receiving groove 710 and a guide groove 720 are provided. The turntable 421 is rotatably disposed in the receiving groove 710, and the bending seat 511 is slidably disposed in the guide groove 720. The first telescopic drive member 320, the rotation drive member, the second telescopic drive member 521, and the third telescopic drive member 620 are all fixedly connected to the base 700. The receiving groove 710 can receive the turntable 421, and the guide groove 720 can guide the horizontal movement of the bending seat 511, making the movement of the bending seat 511 more stable.

[0039] As a preferred embodiment, please refer to Figure 2 and Figure 3 The base 700 has a vertical surface on its side, and the receiving groove 710 is provided on the vertical surface. The platform 200 is fixedly connected to the vertical surface, and one side of the steel plate placed on the platform 200 abuts against the vertical surface, thereby allowing the steel plate to be initially positioned.

[0040] To better understand this utility model, the following is combined with... Figure 1 - Figure 5 The working principle of the technical solution of this utility model will be described in detail below:

[0041] When bending the steel plate, the steel plate is first placed on the bearing surface 210 of the platform 200, ensuring that the second section 120 and the third section 130 of the steel plate are suspended. The first telescopic drive 320 is activated, and its output end extends, thereby driving the clamping seat 310 to move downward until the bottom of the clamping seat 310 presses against the first section 110 of the steel plate. This positions the steel plate and prevents it from moving during bending. Then, the rotation drive is activated, and its output end faces forward. The rotation causes the turntable 421 to rotate forward around the center of the first arc surface 212, thereby causing the bending roller 411 to rotate forward around the first arc surface 212. During the forward rotation of the bending roller 411 around the first arc surface 212, the second section 120 and the third section 130 of the steel plate can be bent downwards until the second section 120 of the steel plate abuts against the first inclined surface 213. After the first bending process, an angle α can be formed between the second section 120 and the first section 110 of the steel plate. Then, the third telescopic drive 620 is activated, and the first... The output end of the three telescopic drive member 620 extends, driving the positioning seat 610 to move downwards until the second inclined surface 613 abuts against the top surface of the second section 120 of the steel plate after the first bend. This allows the bending angle of the second bending process to be determined by the second arc surface 612 and the second inclined surface 613. The second telescopic drive member 521 is then activated, its output end extending and driving the bending seat 511 to move horizontally and gradually approach the third section 130 of the steel plate. During the process of bending section 30, its top slides and abuts against the bottom surface of the third section 130 of the steel plate, thereby pushing the third section 130 of the steel plate to bend upward into a horizontal state. After the above two bending processes, the steel plate forms component 100. When processing component 100 using this steel plate two-bending device, the worker no longer needs to hold the other end of the long strip steel plate during the entire bending process, ensuring the worker's personal safety. Furthermore, after the first bending process is completed, the steel plate can be directly bent in the second bending process, saving the time for the worker to remove the steel plate and readjust the bending position, thus improving processing efficiency.

[0042] The steel plate double-bending device provided by this utility model has the following beneficial effects:

[0043] (1) The bending angle of the first bending process is determined by the first arc surface 212 and the first inclined surface 213. After the first bending process, the first inclined surface 213 abuts against the second segment 120 of the component 100, ensuring that after the first bending process, the second segment 120 and the first segment 110 of the component 100 can form an included angle α.

[0044] (2) The second inclined surface 613 on the positioning seat 610 abuts against the top surface of the second section 120 of the steel plate after the first bend, so that the bending angle of the second bending process can be determined by the second arc surface 612 and the second inclined surface 613. After the second bending process, the second plane 611 abuts against the third section 130 of the component 100, ensuring that after the second bending process, the third section 130 of the component 100 and the second section 120 can form an included angle α.

[0045] (3) When the component 100 is processed using the two-stage bending device of this steel plate, the worker no longer needs to hold the other end of the long strip steel plate during the entire bending process, which ensures the personal safety of the worker. After the first bending process is completed, the steel plate can be directly bent in the second bending process, saving the time for the worker to take out the steel plate and readjust the bending position, which can improve the processing efficiency.

Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
