Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of clamp processing, and more specifically, to a clamp production bending device. Background Technology

[0002] In fields such as pipeline fixing and equipment installation, clamps are commonly used connecting components. They require bending processes to process metal sheets (such as steel strips and galvanized sheets) into ring or U-shaped structures. The bending accuracy and production efficiency directly determine the clamp's assembly adaptability and production capacity. As the demand for clamps in industries such as infrastructure and chemicals develops towards mass production, the drawbacks of traditional clamp production bending equipment are becoming increasingly apparent: existing equipment generally suffers from low bending efficiency and cannot achieve rapid material output and continuous processing, severely restricting the production pace and driving up unit production costs. Traditional clamp bending often uses manual bending machines or simple semi-automatic bending equipment: manual bending machines require operators to manually push the sheet metal and adjust the bending angle, and are limited by human strength. Although simple semi-automatic equipment can replace some manual labor, the machine needs to be stopped after bending, the finished product needs to be removed manually, and then the material needs to be manually loaded for the next processing. The loading and unloading time is long, and the idle time of the equipment is long, resulting in the disadvantage of reduced overall efficiency.

[0003] Therefore, developing a high-efficiency bending device for clamp production that can quickly discharge materials for continuous processing has become an urgent need for the industry to reduce costs and increase efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a clamp production bending device, which solves the technical problems of low bending efficiency and inability to achieve rapid material output and continuous processing in existing devices.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a clamp production bending apparatus, comprising: The equipment rack and the top frame, wherein the top frame is fixed to the equipment rack; The feeding rack and the feeding cut-off assembly are provided, wherein the feeding rack is mounted on the equipment frame and the feeding cut-off assembly is mounted on the feeding rack and the top frame; The upright plate and the continuous bending assembly are provided on the equipment frame surface and the continuous bending assembly is provided on the upright plate and the top frame. The continuous bending assembly includes a rotating shaft, which is connected to the side surface of the top frame by electric drive to rotate horizontally. A forming mold base is provided at one end of the rotating shaft. Forming grooves are provided on both the upper and lower surfaces of the forming mold base, and one side of the top of the forming groove has an open structure.

[0006] As a further technical solution, the surface of the equipment frame is provided with a feeding port, which is located directly below the forming mold base. The surface of the equipment frame is provided with a pair of slide rails, which are located on both sides of the feeding port, and support seats are connected to the slide rails.

[0007] As a further technical solution, a telescopic cylinder is horizontally installed on the equipment frame, the output end of the telescopic cylinder is connected to the support base, the support base slides against the bottom surface of the forming mold base, and a forming hydraulic cylinder is vertically installed on the top of the top frame, with a forming extrusion block installed at the output end of the forming hydraulic cylinder.

[0008] According to another aspect, in at least one embodiment of the present invention, the feeding and cutting assembly includes a feeding trough, which is opened on the top of the feeding frame. Conveying wheels are rotatably connected in both the feeding trough and the feeding frame, and one of the conveying wheels is driven to rotate by electricity.

[0009] As a further technical solution, a second hydraulic cylinder is vertically arranged on the top of the top frame, and a cutting blade holder is arranged at the output end of the second hydraulic cylinder. The cutting blade holder slides against the side end face of the feed frame.

[0010] As a further technical solution, the cutting blade holder is located between the feeding rack and the forming mold base, and both sides of the cutting blade holder are simultaneously slidably attached to the feeding rack and the forming mold base.

[0012] As a further technical solution, a second cylinder is provided on the top frame, and a pressure plate is provided at the output end of the second cylinder, with the pressure plate located on one side above the forming mold base.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the continuous bending assembly solves the problems of low bending efficiency and inability to process continuously in traditional devices through a flip-over switching and automatic unloading design. The upper and lower forming grooves of the forming die base, combined with the rotating shaft, allow for rapid switching of workstations and prevent idle running. The support base and telescopic cylinder work together to ensure the stability of the die base during bending and to quickly avoid obstacles for automatic unloading. The forming hydraulic cylinder provides stable extrusion force, ensuring consistent bending accuracy of the clamps. This structure eliminates the need for manual die changing and material handling, enabling uninterrupted continuous bending, significantly shortening the processing cycle, adapting to the needs of mass production of clamps, and simultaneously preventing workpiece damage through automatic unloading, improving product qualification rate, and laying the foundation for efficient production.

[0022] like Figures 1-3 As shown, it illustrates a clamp production bending apparatus according to an embodiment of the present disclosure, comprising: Equipment frame 1 and top frame 2, wherein the top frame 2 is fixed on the equipment frame 1; The feeding rack 3 and the feeding cut-off assembly 6 are provided. The feeding rack 3 is mounted on the equipment frame 1, and the feeding cut-off assembly 6 is mounted on the feeding rack 3 and the top frame 2. The upright plate 4 and the continuous bending assembly 5 are provided on the upright plate 4 and the top frame 2, respectively. The continuous bending assembly 5 includes a rotating shaft 5-1, which is horizontally connected to the side surface of the top frame 2 via electric drive. A forming mold base 5-2 is provided at one end of the rotating shaft 5-1. Forming grooves 5-3 are provided on both the upper and lower surfaces of the forming mold base 5-2. One side of the top of the forming groove 5-3 is open. A discharge port 5-4 is provided on the surface of the equipment frame 1, which is located directly below the forming mold base 5-2. A pair of slide rails 5-5 are provided on the surface of the equipment frame 1, which are located on both sides of the discharge port 5-4. A support seat 5-6 is connected to the slide rail 5-5. A telescopic cylinder 5-7 is horizontally installed on the equipment frame 1. The output end of the telescopic cylinder 5-7 is connected to the support seat 5-6. The support seat 5-6 slides against the bottom surface of the forming mold base 5-2. A forming hydraulic cylinder 5-8 is vertically provided on the top of the top frame 2. A forming extrusion block 5-9 is provided at the output end of the forming hydraulic cylinder 5-8.

[0023] In some examples, to achieve continuous bending and automatic unloading in the production process of clamps, and to avoid the inefficiency caused by frequent mold changes in traditional bending devices, or the accumulation of workpieces due to poor unloading, a continuous bending component 5 was designed to meet the requirements of continuity and efficiency in the mass production of clamps. This component includes a rotating shaft 5-1 that rotates horizontally on the side surface of the top frame 2 via electric drive, providing the flipping power for the forming mold base 5-2. The forming mold base 5-2 at one end of the rotating shaft 5-1 can rotate synchronously with the rotating shaft 5-1. The forming grooves 5-3 on its upper and lower surfaces can be switched for use by flipping. When the upper forming groove 5-3 completes one bend, the rotating shaft 5-1 drives the forming mold base 5-2 to rotate 180°, and the lower forming groove 5-3 can be switched to the working position, realizing uninterrupted continuous bending and greatly improving production efficiency.

[0024] The opening on one side of the top of the forming groove 5-3 facilitates the insertion of sheet metal and the removal of bent workpieces, avoiding workpiece jamming caused by a closed structure. The discharge port 5-4 on the surface of the equipment frame 1 is located directly below the forming mold base 5-2, providing a falling channel for the bent clamp workpiece, ensuring that the workpiece can quickly detach from the forming mold base 5-2, and preventing the workpiece from adhering to the mold base surface and affecting subsequent bending.

[0025] The slide rails 5-5 on both sides of the discharge port 5-4 provide horizontal sliding guidance for the support seat 5-6. Driven by the telescopic cylinder 5-7, the support seat 5-6 can move closer to or further away from the forming mold base 5-2 along the slide rail 5-5. When the forming mold base 5-2 is bent, the support seat 5-6 slides against the bottom surface of the forming mold base 5-2 to provide bottom support for the mold base, prevent the mold base from deforming downward due to force, and ensure bending accuracy.

[0026] After bending is completed, the support seat 5-6 moves away from the mold seat under the action of the telescopic cylinder 5-7, exposing the discharge port 5-4, and the workpiece can then fall down along the discharge port 5-4 to complete the automatic unloading.

[0027] The forming hydraulic cylinder 5-8 is vertically set at the top of the top frame 2. The forming extrusion block 5-9 at the output end can move vertically downward under hydraulic drive to extrude the plate placed in the forming groove 5-3, so that the plate is bent into a clamp structure along the shape of the forming groove 5-3.

[0028] Hydraulic drive provides stable and adjustable extrusion pressure, adapting to the bending requirements of plates of different thicknesses, ensuring precise bending angles and consistent forming quality of the clamps.

[0029] During operation, the sheet metal is placed into the forming groove 5-3, and the forming hydraulic cylinder 5-8 drives the extrusion block to bend. After bending, the telescopic cylinder 5-7 moves the support seat 5-6 to avoid a collision, and the workpiece falls through the discharge port 5-4. The rotating shaft 5-1 drives the mold base to flip, switching the forming groove 5-3 for the next bending. The flipping and switching enables continuous operation, the hydraulic drive ensures bending accuracy, and the synchronous feeding improves efficiency. All components work together to achieve continuous bending and automatic feeding of the clamp, meeting the needs of mass production.

[0030] like Figures 1-3 As shown in the figure, the feeding and cutting assembly 6 in this embodiment includes a feeding trough 6-1, which is opened on the top of the feeding frame 3. Conveying wheels 6-2 are rotatably connected in both the feeding trough 6-1 and the feeding frame 3. One of the conveying wheels 6-2 is driven to rotate by electricity. A second hydraulic cylinder 6-3 is vertically arranged on the top of the top frame 2. A cutting blade holder 6-4 is arranged at the output end of the second hydraulic cylinder 6-3. The cutting blade holder 6-4 is slidably attached to the side end face of the feeding frame 3.

[0031] In some examples, in order to achieve stable conveying of the plates used for clamp production and accurate cutting after forming, and to avoid deviation of the bending position caused by the offset of the plates during the conveying process, or incomplete cutting that causes the workpiece to be scrapped, a feeding and cutting assembly 6 is designed. This assembly includes a feeding groove 6-1 at the top of the feeding frame 3, which provides a conveying channel for the plates and can limit the lateral offset of the plates during the conveying process, ensuring that the plates move stably along the preset path.

[0032] The conveyor wheel 6-2 is rotatably connected to the feed rack 3 inside the feed trough 6-1. One of the wheels is driven by electricity to rotate. The friction between the conveyor wheel 6-2 and the surface of the plate drives the plate forward. The rotation speed of the conveyor wheel 6-2 can be precisely controlled, thereby adjusting the plate conveying speed and conveying length to adapt to the plate length requirements of different specifications of clamps and realize quantitative conveying of plates.

[0033] The second hydraulic cylinder 6-3, which is vertically mounted on the top of the top frame 2, provides cutting power to the cutting tool holder 6-4. The cutting tool holder 6-4 at the output end of the second hydraulic cylinder 6-3 can move vertically downward under hydraulic drive to cut the plate that has been transported to the designated position.

[0034] The cutting tool holder 6-4 slides against the side end face of the feed rack 3. The side end face of the feed rack 3 can provide vertical guidance for the cutting tool holder 6-4, preventing the cutting tool holder 6-4 from tilting during movement, ensuring a flat cutting surface, reducing burrs on the plate, and improving the appearance quality and dimensional accuracy of the clamped workpiece.

[0035] The blade shape of the cutting tool holder 6-4 is adapted to the thickness of the sheet metal, which can achieve a complete cut in one go and avoid the sheet metal from sticking together due to incomplete cutting, which would affect subsequent bending operations.

[0036] During operation, the sheet metal is placed into the feed trough 6-1, and the conveyor wheel 6-2 drives the sheet metal to be quantitatively conveyed to the cutting position. The second hydraulic cylinder 6-3 drives the cutting blade holder 6-4 to cut the sheet metal downwards. The cut sheet metal is then conveyed to the continuous bending assembly 5 for bending. Stable conveying ensures accurate positioning of the sheet metal, and hydraulic cutting ensures cutting quality. The coordinated operation of all components achieves stable conveying of the sheet metal and rapid cutting after forming, providing reliable feeding and cutting guarantees for continuous production of clamps, and improving overall production efficiency and product quality.

[0037] For example, such as Figure 3 As shown, the cutting blade holder 6-4 is located between the feeding rack 3 and the forming mold base 5-2, and both sides of the cutting blade holder 6-4 are simultaneously slidably attached to the feeding rack 3 and the forming mold base 5-2.

[0038] In some examples, the cutting tool holder 6-4 is located between the feed rack 3 and the forming mold base 5-2, and both sides slide against the feed rack 3 and the forming mold base 5-2. This position design allows the cut plate to directly enter the forming groove 5-3 of the forming mold base 5-2, shortening the plate transfer path, avoiding plate shifting during transfer, ensuring accurate connection of the plate to the bending station, and improving production continuity.

[0039] For example, such as Figure 1 As shown, a sliding hopper 7 is provided at the bottom of the equipment frame 1, and the sliding hopper 7 is located directly below the discharge port 5-4.

[0040] In some examples, the sliding hopper 7 at the bottom of the equipment frame 1 is located directly below the discharge port 5-4. It can receive the bent clamp workpiece falling from the discharge port 5-4, preventing the workpiece from falling directly to the ground and causing collision damage, thus protecting the appearance and forming accuracy of the workpiece. The interior of the sliding hopper 7 can be designed with an inclined structure, using gravity to guide the workpiece to slide in a designated direction, realizing the centralized collection and orderly transportation of workpieces. This facilitates subsequent sorting, inspection, or further processing of the workpieces, and avoids the workpieces piling up and becoming chaotic.

[0041] For example, such as Figure 1 As shown, a second cylinder 8 is provided on the top frame 2, and a pressure plate 9 is provided at the output end of the second cylinder 8. The pressure plate 9 is located on one side above the forming mold base 5-2.

[0042] In some examples, the pressure plate 9 at the output end of the second cylinder 8 on the top frame 2 is located on one side above the forming mold base 5-2. When the sheet metal is placed into the forming groove 5-3 for bending, the second cylinder 8 drives the pressure plate 9 to move downward, pressing the edge of the sheet metal against the surface of the forming mold base 5-2. This prevents the sheet metal from shifting or warping under the pressure of the forming extrusion block 5-9, ensuring accurate bending and improving the forming precision of the clamp. The clamping force of the pressure plate 9 can be controlled by adjusting the air pressure of the second cylinder 8 to adapt to the clamping requirements of sheets of different thicknesses, avoiding excessive pressure that could deform the sheet metal or insufficient pressure that would not provide a fixing effect.

[0043] In actual use: The sheet metal for clamp production is placed into the feeding groove 6-1 of the feeding rack 3. The electric drive of the feeding and cutting assembly 6 is started, and the conveying wheel 6-2 drives the sheet metal to be quantitatively conveyed along the feeding groove 6-1 to the cutting position. The second hydraulic cylinder 6-3 is started, driving the cutting blade holder 6-4 to slide vertically downward, accurately cutting the sheet metal. The cut sheet metal is directly conveyed to the forming mold base 5-2 of the continuous bending assembly 5. At this time, the support base 5-6 is attached to the bottom surface of the forming mold base 5-2 under the drive of the telescopic cylinder 5-7. The second cylinder 8 pushes the pressure plate 9 to press the edge of the sheet metal. The forming hydraulic cylinder 5-8 drives the forming extrusion block 5-9 to move downward, pressing the sheet metal into the forming groove 5-3 to complete the bending. After bending, the telescopic cylinder 5-7 drives the support seat 5-6 away from the mold base along the slide rail 5-5, and the clamping workpiece falls into the sliding hopper 7 through the discharge port 5-4. At the same time, the rotating shaft 5-1 drives the forming mold base 5-2 to flip and switch to another forming groove 5-3. The above process is repeated to achieve continuous processing. The entire process does not require frequent manual loading and unloading and mold changing, realizing automated continuous production of clamps and greatly improving processing efficiency.
