Description

A high-efficiency sheet metal bending processing device Technical Field

[0001] This utility model relates to the field of bending processing equipment technology, and in particular to a high-efficiency sheet metal bending processing device. Background Technology

[0002] In industrial production, many of the frames, supports, and shells of various equipment are sheet metal parts, and some of these sheet metal parts need to be bent using bending processing equipment.

[0003] The bending processing device performs top-pressure bending processing on sheet metal parts by engaging the tapered tip of its top-pressure bending component with the bending groove on the load-bearing component. To meet the processing requirements of different bending angles of sheet metal parts, the top-pressure bending component and the bending groove are set in multiple locations and in various specifications. To facilitate the switching between various specifications of top-pressure bending components and bending grooves, the mounting mechanism for installing various specifications of top-pressure bending components and the load-bearing component with various specifications of bending grooves are mostly set to be rotatable and adjustable. During the top-pressure bending process, an upward thrust is generated on the mounting mechanism and a downward pressure is generated on the load-bearing component. Existing bending processing devices often lack components to distribute the thrust and pressure, causing the mounting mechanism and the load-bearing component to rely on the mounting component that is installed on it through its rotational engagement with its shaft to bear the large thrust and pressure. This makes the mounting component prone to being pushed and broken, affecting the normal and continuous use of the bending processing device. Summary of the Invention

[0004] In view of this, the present invention provides a high-efficiency sheet metal bending processing device to solve the problem that existing bending processing devices often lack components to distribute and bear the counter-thrust and top pressure, causing the mounting mechanism and load-bearing components to rely on the mounting components that rotate with their shafts to bear the large counter-thrust and top pressure, resulting in the mounting components being easily pushed and broken.

[0005] The technical solution proposed by this utility model is: a high-efficiency sheet metal bending processing device, specifically including a horizontal platform plate and a horizontal sliding plate. The horizontal sliding plate is slidably arranged above the horizontal platform plate, and two vertical guide rods are symmetrically welded to the top of the horizontal platform plate and the bottom of the horizontal sliding plate.

[0006] The vertical guide rod is slidably mounted with sliding mounting parts by means of spring push. A top-pressure bending assembly is rotatably arranged between the two upper sliding mounting parts, and a three-pronged bearing assembly is rotatably arranged between the two lower sliding mounting parts. The top-pressure bending assembly consists of a rotating shaft and three top-pressure plates welded around the outer circumference of the rotating shaft. The three-pronged bearing assembly is integrally formed by three surrounding bearing square rods. The top of the horizontal platform plate and the bottom of the horizontal sliding plate are respectively fixedly connected to a horizontal load-bearing plate and a horizontal force-bearing plate. Three trapezoidal slots are formed between the three top-pressure plates. The bottom part of the horizontal force-bearing plate has a trapezoidal structure, which can be selectively inserted into the three trapezoidal slots. Three triangular slots are formed between the three bearing square rods. The top part of the horizontal load-bearing plate has a triangular structure, which can be selectively inserted into the three triangular slots.

[0007] Furthermore, two short rotating posts are symmetrically welded at the center positions of both ends of the three-pronged bearing assembly. The sliding mounting component consists of a U-shaped sliding frame and a mounting ring integrally formed at the opening end of the U-shaped sliding frame. The two ends of the rotating shaft are respectively rotatably engaged with the two upper mounting rings, and the two short rotating posts are respectively rotatably engaged with the two lower mounting rings.

[0008] Furthermore, the horizontal load-bearing plate is located between the two vertical guide rods on the upper side, and the horizontal load-bearing plate is located between the two vertical guide rods on the lower side.

[0009] Furthermore, a baffle is welded to the first end of the vertical guide rod, the longitudinal side plate of the U-shaped slide frame slides in conjunction with the vertical guide rod, and the spring that pushes the sliding installation part is fitted on the vertical guide rod and compressed and clamped between the longitudinal side plate of the U-shaped slide frame and the baffle.

[0010] Furthermore, a U-shaped vertical support frame is welded to the top of the platform plate, and a horizontal slide plate is slidably installed on the U-shaped vertical support frame. A hydraulic cylinder is fixedly hoisted on the bottom side of the middle part of the top of the U-shaped vertical support frame, and the bottom end of the piston rod of the hydraulic cylinder is fixedly connected to the horizontal slide plate.

[0011] Furthermore, the side of the top pressure plate away from the rotating shaft has a tapered structure, and the included angle between the two inclined sides of the tapered structure is the first included angle;

[0012] A V-shaped bending groove is provided on the side of the bearing square rod away from the center line of the three-pronged bearing component. The included angle of the V-shaped bending groove is the second included angle. The angles of the three first included angles and the three second included angles are equal. The conical structure and the V-shaped bending groove with the same included angle are directly opposite each other and are mutually compatible.

[0013] The present invention provides a high-efficiency sheet metal bending processing device, which has the following beneficial effects:

[0014] 1. When the horizontal load-bearing plate and the horizontal load-bearing plate are respectively inserted into the triangular slot and the trapezoidal slot, they can assist in bearing and dispersing the counter-thrust force generated on the top-pressure bending component and the downward pressure on the three-pronged load-bearing component. This avoids the top-pressure bending component and the three-pronged load-bearing component relying solely on their relatively thin sliding mounting parts on their corresponding sides to support the above two forces, which would make the sliding mounting parts easily broken and damaged. This helps to ensure the normal and effective use of the bending processing device.

[0015] Second, the top-pressure bending assembly and the three-pronged load-bearing assembly can be used as rotation positioning components for the top-pressure bending assembly and the three-pronged load-bearing assembly, respectively, and can also be used as load-bearing force components for the top-pressure bending assembly and the three-pronged load-bearing assembly, respectively. This has the effect of using one device for two purposes. This effect can save the need to configure rotation positioning components separately for the top-pressure bending assembly and the three-pronged load-bearing assembly, which helps to simplify the structure of the bending processing device to a certain extent.

The top-pressure bending assembly 4 consists of a rotating shaft 402 and three top pressure plates 401 welded around the outer periphery of the rotating shaft 402. The three-pronged bearing assembly 6 is integrally formed by three surrounding bearing square rods 601.

The top part of the horizontal load-bearing plate 103 has a triangular structure, which can be selectively inserted into the three triangular slots.

[0037] Preferably, two short rotating posts 602 are symmetrically welded at the center positions of both ends of the three-pronged bearing component 6. The sliding mounting component 5 is composed of a U-shaped sliding frame 501 and a mounting ring 502 integrally formed at the opening end of the U-shaped sliding frame 501.

[0038] Preferably, the horizontal load-bearing plate 103 is located between the two vertical guide rods 7 on the upper side, and the horizontal load-bearing plate 301 is located between the two vertical guide rods 7 on the lower side.

[0039] Preferably, a baffle 701 is welded to the first end of the vertical guide rod 7, the longitudinal side plate of the U-shaped slide frame 501 is slidably engaged with the vertical guide rod 7, and the spring that pushes the sliding mounting part 5 is fitted on the vertical guide rod 7 and compressed and clamped between the longitudinal side plate of the U-shaped slide frame 501 and the baffle 701.

[0040] Implementation 2: This embodiment is based on Implementation 1, but with the following additions:

[0041] A U-shaped vertical support frame 102 is welded to the top of the platform plate 1. The horizontal slide plate 3 is slidably installed on the U-shaped vertical support frame 102.

[0042] Preferably, the top pressure plate 401 has a tapered structure on the side away from the rotating shaft 402, and the included angle between the two inclined sides of the tapered structure is the first included angle; a V-shaped bending groove is provided on the side of the bearing square rod 601 away from the center line of the three-pronged bearing component 6, and the included angle of the V-shaped bending groove is the second included angle. The angles of the three first included angles and the three second included angles are equal, and the tapered structure and the V-shaped bending groove with equal included angles are directly opposite each other and are compatible with each other.

[0043] Preferably, two vertical supports 101 are symmetrically welded to the bottom ends of the two short sides of the platform plate 1, and an installation box 8 is welded between the lower halves of the two vertical supports 101. A hydraulic power unit is installed inside the installation box 8, and the hydraulic cylinder 2 is connected to the hydraulic power unit through a high-pressure oil pipe.

[0044] The following section provides a detailed explanation of the working principles, specific details, implementation steps, functions and interrelationships of each feature, and their roles in realizing this technical solution:

[0045] In use, the sheet metal part to be bent is first placed on the top of the vertical support rod 601. Then, the piston rod of the hydraulic cylinder 2 is controlled to slide down and extend. When the piston rod of the hydraulic cylinder 2 slides down and extends, it drives the horizontal slide plate 3, the horizontal force plate 301 and the top pressure bending assembly 4 to move down. As the piston of the hydraulic cylinder 2 continues to slide down, the bottom conical structure of the vertical top pressure plate 401 contacts the sheet metal part and presses the bent part of the sheet metal part into the V-shaped bending groove at the top of the vertical support rod 601 to bend the sheet metal part. After the sheet metal part is bent into shape, the piston rod of the hydraulic cylinder 2 is controlled to slide up and retract. When the piston rod of the hydraulic cylinder 2 slides up, it drives the top pressure bending assembly 4 to move up and reset, and releases the formed sheet metal part. Finally, the formed sheet metal part is removed from the top of the vertical support rod 601.

[0046] By adjusting the angles of the first and second included angles, sheet metal parts can be bent at different angles. In this invention, the angles of the three first included angles and the three second included angles increase sequentially and are equal. By rotating the top-pressing bending assembly 4 and the three-pronged bearing assembly 6, the three top-pressing plates 401 and the three bearing square rods 601 can be rotated and switched to a vertical support posture. The conical structure of the top-pressing bending assembly 4 with different included angles and the V-shaped bending grooves with different angles are switched and adjusted to the bending use state, thereby indirectly realizing the adjustment of the first and second included angles. This allows the bending processing device to meet the processing requirements of sheet metal parts with different bending angles, and its application is quite widespread.

[0047] When the trapezoidal portion at the bottom of the horizontal load-bearing plate 301 is engaged with the corresponding trapezoidal slot, the top pressure plate 401 used for bending can be positioned in a vertical support state; when the triangular portion at the top of the horizontal load-bearing plate 103 is engaged with the corresponding triangular slot, the load-bearing square rod 601 used for bending can be positioned in a vertical support state; the springs on the two vertical guide rods 7 on the upper side can push and hold the two sliding mounting parts 5 on the upper side and the top pressure bending assembly 4 in an upward sliding high position, so that the trapezoidal portion at the bottom of the horizontal load-bearing plate 301 The trapezoidal slots at corresponding positions are positioned in a plug-in engagement state. Manually lowering the sliding top-pressure bending assembly 4 can cause the two upper sliding mounting parts 5 to compress the two springs and move downwards synchronously. During this process, when the trapezoidal slots separate from the horizontal force plate 301, the top-pressure bending assembly 4 is released, allowing for rotational switching and adjustment of the three top pressure plates 401. After the switching operation is completed, the downward force exerted by the hand on the top-pressure bending assembly 4 is released, and the top-pressure bending assembly 4 can move downwards under the counter-push of the two compressed springs. The sliding mechanism resets and controls the trapezoidal slots at the corresponding positions to engage with the horizontal load-bearing plate 301, repositioning the three top pressure plates 401 after the switch and adjustment. Springs on the two lower vertical guide rods 7 push the two lower sliding mounting parts 5 and the triangular bearing assembly 6 to maintain them in a high sliding position, ensuring the triangular portion at the top of the horizontal load-bearing plate 103 and the corresponding triangular slots are in a properly engaged position. Manually raising and sliding the triangular bearing assembly 6 compresses the two lower sliding mounting parts 5. The spring moves upward synchronously. During this process, when the triangular slot separates from the horizontal support plate 103, the three-pronged support assembly 6 is released, enabling the rotation and switching adjustment of the three support rods 601. After the switching operation is completed, the upward sliding force exerted by the hand on the three-pronged support assembly 6 is released. Under the counter-push of the two compressed springs, the three-pronged support assembly 6 can automatically slide down to reset and control the triangular slot at the corresponding position to engage with the horizontal support plate 103, thereby repositioning the three support rods 601 after the switching adjustment.

[0048] During the bending process, when the top-pressure bending assembly 4 is driven to slide down and the conical structure of the top pressure plate 401 in the vertical bending state comes into contact with the sheet metal, the downward pressure of the hydraulic cylinder 2 on the sheet metal is pushed back onto the top-pressure bending assembly 4 through the bearing square rod 601 in the vertical bending state. At the same time, the downward pressure of the hydraulic cylinder 2 on the sheet metal is directly transmitted to the three-pronged bearing assembly 6. When the horizontal bearing plate 103 and the horizontal load-bearing plate 301 are respectively inserted into the triangular slot and the trapezoidal slot, they can provide auxiliary bearing and dispersion for the counter-push force generated on the top-pressure bending assembly 4 and the downward pressure on the three-pronged bearing assembly 6. This avoids the top-pressure bending assembly 4 and the three-pronged bearing assembly 6 relying solely on their relatively thin sliding mounting parts 5 on their corresponding sides to support the above two forces, which would make the sliding mounting parts 5 easily broken and damaged. This helps to ensure the normal and effective use of the bending processing device.

[0049] The top-pressure bending assembly 4 and the three-pronged bearing assembly 6 can be used as rotation positioning components for the top-pressure bending assembly 4 and the three-pronged bearing assembly 6, respectively, and can also be used as load-bearing force components for the top-pressure bending assembly 4 and the three-pronged bearing assembly 6, respectively. This dual-purpose function eliminates the need to separately configure rotation positioning components for the top-pressure bending assembly 4 and the three-pronged bearing assembly 6, which helps to simplify the structure of the bending processing device to a certain extent.

[0050] It is worth noting that the telescopic control system of hydraulic cylinder 2 and the control principle of the system are existing technologies for technicians engaged in equipment modification, design, testing and upgrading in this field, so they will not be described in detail here.

[0051] The following points should be noted in this article:

[0052] 1. The accompanying drawings of this utility model embodiment only involve the structure involved in this utility model embodiment; other structures can refer to general designs.

[0053] 2. Where there is no conflict, the embodiments of this utility model and the features in the embodiments can be combined with each other to obtain new embodiments.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
