Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of clamp processing, specifically to a U-shaped clamp processing device. Background Technology

[0002] U-shaped clamps are widely used in building pipeline fixing and electrical equipment installation due to their simple structure and reliable fixing characteristics. Their processing quality and efficiency directly affect the construction progress of downstream industries. Currently, with urbanization and industrial equipment upgrades, the market demand for U-shaped clamps continues to grow. However, the performance defects of traditional U-shaped clamp processing equipment are becoming increasingly apparent. The core problems are low continuous processing efficiency and the inability to quickly replenish raw materials and quickly discharge materials after forming, which seriously restricts large-scale production and drives up enterprise operating costs. Traditional U-shaped clamp processing devices are mostly semi-manual or single-machine intermittent operation modes: in the raw material replenishment stage, it is necessary to manually disassemble bundles of metal sheets and transport them to the processing station piece by piece. If the raw materials are misaligned, they need to be recalibrated, which further prolongs the interruption time. After the forming process is completed, the finished products need to be manually removed from the mold one by one. During the material removal process, improper operation can easily cause the finished products to deform, requiring additional manpower for repair. Therefore, the development of U-shaped clamp processing equipment that can improve continuous processing efficiency, enable rapid replenishment of raw materials and rapid discharge after forming has become an urgent need for the industry to break through production capacity bottlenecks and ensure product quality. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a U-shaped clamp processing device, which solves the technical problem that the prior art cannot achieve rapid replenishment of raw materials and rapid discharge after forming.

[0004] According to one aspect, at least one embodiment of the present disclosure provides a U-shaped clamp processing apparatus, comprising: A frame and a through-hole, the through-hole being formed on the surface of the frame; A feeding assembly is mounted on the frame; A molding and processing assembly is disposed on the surface of the frame; The forming and processing assembly includes a flip plate, which is rotatably connected to the frame via a rotating shaft. The flip plate is located above the opening and is rotated by electric drive. A forming groove is formed around the side surface of the flip plate. A fixed seat is provided on the surface of the frame, and a bending sleeve is connected to the side surface of the fixed seat via a horizontal linear drive.

[0005] As a further technical solution, the bottom surface of the bending sleeve is slidably attached to the surface of the platform. Both ends of the platform surface are horizontally mounted with bosses. A telescopic cylinder is horizontally mounted on the side surface of the boss. A tightening frame is provided at the output end of the telescopic cylinder. The tightening frame is fitted and attached to both sides of the flip plate.

[0006] According to another aspect, in at least one embodiment of the present invention, the feeding assembly includes a pair of uprights, the uprights being fixed at both ends of the platform surface, and a notch being provided in the lower end of the uprights, with a swinging sleeve block being horizontally rotatably connected to the notch via a pin.

[0007] As a further technical solution, a feeding groove is provided on both the side surface of the upright frame and the side end face of the swing sleeve block. An outer plate is provided at the lower end of the side surface of the upright frame, and a return spring is connected between the outer plate and the side end face of the swing sleeve block.

[0008] As a further technical solution, the clamping frame has an overall U-shaped structure, and the top of both ends of the clamping frame are sloping transition structures.

[0009] As a further technical solution, a conveyor belt is provided at the bottom of the platform, and the conveyor belt is located below the opening.

[0010] As a further technical solution, the spacing between the uprights and the height within the notch are matched with the length and diameter of the clamp material.

[0011] As a further technical solution, the swing sleeve can rotate up to 90° to one side through the pin connection.

[0012] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the molding and processing component solves the problems of low molding efficiency and reliance on manual material handling in traditional devices through a flip-over switching and multi-directional fixing design. The rotating flip plate enables alternating use of the molding slots, and the conveyor belt automatically collects the clamps, avoiding production interruptions caused by manual material handling. The horizontal drive of the bending sleeve ensures consistent clamp molding accuracy, and the U-shaped clamping frame fixes the flip plate from both sides to prevent displacement during processing. This structure eliminates the need for machine stoppage for mold changing or material handling, enabling continuous molding and automatic material handling of U-shaped clamps, significantly increasing the output per unit time. At the same time, multi-directional fixing ensures accurate molding dimensions, reduces errors caused by manual operation, and is suitable for the dual requirements of efficiency and quality in mass production.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figures 1-4 As shown, it illustrates a U-shaped clamp processing device according to an embodiment of the present disclosure, comprising: A frame 1 and a through-hole 2, wherein the through-hole 2 is formed on the surface of the frame 1; The feeding assembly 4 is mounted on the frame 1; A molding and processing component 3 is disposed on the surface of the frame 1; The forming and processing component 3 includes a flipping plate 3-1, which is rotatably connected to the frame 1 via a rotating shaft. The flipping plate 3-1 is located above the opening 2 and is driven to rotate by electricity. A forming groove 3-2 is formed around the side surface of the flipping plate 3-1. A fixed seat 3-3 is provided on the surface of the frame 1. A bending sleeve 3-4 is connected to the side surface of the fixed seat 3-3 via a horizontal linear drive. The bottom surface of the bending sleeve 3-4 slides against the surface of the frame 1. Bosses 3-5 are horizontally installed at both ends of the surface of the frame 1. Telescopic cylinders 3-6 are horizontally installed on the side surfaces of the bosses 3-5. A clamping frame 3-7 is provided at the output end of the telescopic cylinder 3-6. The clamping frame 3-7 is fitted and attached to both sides of the flipping plate 3-1.

[0022] In some examples, to achieve automatic flipping and continuous processing of U-shaped clamps after forming, avoiding the efficiency bottleneck caused by manual material handling in traditional processing, or the impact of workpiece jamming on production continuity after forming, and to meet the requirements of high efficiency and stability for mass production of U-shaped clamps, a forming processing component 3 was designed. This component includes a flipping plate 3-1 above the opening 2 on the surface of the frame 1, which is rotatably connected to the frame 1 via a rotating shaft. Electric drive can drive the flipping plate 3-1 to rotate stably around the rotating shaft. The forming grooves 3-2 around its side surface can be switched for use by flipping. When one forming groove 3-2 has completed bending and forming, the flipping plate 3-1 rotates, causing the formed clamp to rotate with the forming groove 3-2 to the position of the opening 2. Under the action of gravity, it automatically falls through the opening 2 to complete the unloading. At the same time, another empty forming groove 3-2 is switched to the processing station to achieve uninterrupted continuous processing and significantly increase the processing volume per unit time.

[0023] The fixed seat 3-3 on the surface of the platform 1 provides an installation base for the bending sleeve 3-4. The bending sleeve 3-4, which is connected to the side surface of the fixed seat 3-3 by a horizontal linear drive, can slide horizontally along the surface of the platform 1. Its bottom surface slides and fits against the surface of the platform 1 to ensure no offset during movement.

[0024] After the raw material is placed into the forming groove 3-2, the bending sleeve 3-4 moves towards the flipping plate 3-1, fits onto the outside of the raw material and applies pressure. In accordance with the shape of the forming groove 3-2, the raw material is bent into a U-shaped structure. The horizontal linear drive can accurately control the bending force and displacement, adapt to the forming requirements of raw materials of different thicknesses, and ensure that the bending angle of the clamp is consistent and the forming quality is stable.

[0025] The telescopic cylinders 3-6 on the side surfaces of the protrusions 3-5 at both ends of the frame 1, and the clamping frame 3-7 at the output end can move towards the flipping plate 3-1 under the drive of the cylinders. When the flipping plate 3-1 is in the processing position, the clamping frame 3-7 is fitted and attached to the flipping plate 3-1 from both sides, forming a lateral fixation on the flipping plate 3-1, preventing the flipping plate 3-1 from rotating and shifting due to force during the bending process, and ensuring the bending accuracy. After the forming is completed, the telescopic cylinders 3-6 drive the clamping frame 3-7 to reset, releasing the flipping plate 3-1 so that it can rotate and unload.

[0026] During operation, the clamping frame 3-7 fixes the flipping plate 3-1, and the bending frame 3-4 bends the raw material. After forming, the clamping frame 3-7 resets, the flipping plate 3-1 rotates to allow the clamp to fall through the through-hole 2, and at the same time, the forming groove 3-2 is switched to continue processing. The flipping and switching enables continuous operation, multi-directional fixing ensures forming accuracy, automatic feeding improves efficiency, and the coordinated operation of various components realizes U-shaped clamp forming, flipping feeding and continuous processing to meet the needs of mass production.

[0027] like Figures 1-4As shown in the figure, the feeding assembly 4 in this embodiment includes a pair of uprights 4-1. The uprights 4-1 are fixed at both ends of the surface of the platform 1. A notch 4-2 is opened in the lower end of the uprights 4-1. A swinging sleeve block 4-3 is horizontally rotatably connected in the notch 4-2 by a pin. Feeding grooves 4-4 are opened on the side surface of the uprights 4-1 and the side end face of the swinging sleeve block 4-3. An outer plate 4-5 is provided at the lower end of the side surface of the uprights 4-1. A return spring 4-6 is connected between the outer plate 4-5 and the side end face of the swinging sleeve block 4-3.

[0028] In some examples, in order to achieve continuous replenishment of raw materials for U-shaped clamp production and to accurately push the raw materials to the forming station in conjunction with the bending sleeve 3-4, avoiding the interruption of raw material replenishment and resulting in empty forming components, a feeding component 4 is designed. This component includes a stand 4-1 fixed at both ends of the surface of the platform 1, which provides installation support for components such as the swing sleeve 4-3 and the return spring 4-6. The swing sleeve 4-3, which rotates horizontally through a pin in the notch 4-2 at the lower end of the stand 4-1, can swing left and right around the pin in the notch 4-2. Its side end face corresponds to the feeding groove 4-4 opened on the side surface of the stand 4-1. When the raw material is put into the feeding groove 4-4, it can slide along the groove into the swing sleeve 4-3. The feeding groove 4-4 can provide initial guidance for the raw material and prevent the raw material from shifting laterally.

[0029] The return spring 4-6 connected between the lower end outer plate 4-5 of the side surface of the upright 4-1 and the side end face of the swing sleeve block 4-3 has an elastic return function. When the raw material is pushed to the forming station, the swing sleeve block 4-3 returns to the initial position under the elastic force of the return spring 4-6 so as to receive the next raw material and realize the continuous feeding of raw materials.

[0030] The spring force can be adjusted according to the weight of the raw material to ensure that it can stably support the raw material and swing smoothly when the raw material is pushed, avoiding the raw material getting stuck due to excessive spring force or the inability to reset due to insufficient spring force.

[0031] When the feeding assembly 4 works in conjunction with the bending sleeve 3-4, the bending sleeve 3-4 can push the raw material on the swing sleeve 4-3 to move synchronously as it moves toward the forming station. At this time, the swing sleeve 4-3 swings downward around the pin axis to make room for the raw material to be fed. After the bending sleeve 3-4 pushes the raw material into the forming groove 3-2, the swing sleeve 4-3 is reset under the action of the return spring 4-6, ready for the next feeding.

[0032] The guiding function of the feeding trough 4-4 and the pushing function of the bending sleeve 3-4 are combined to ensure that the raw material can accurately enter the forming trough 3-2 and avoid pushing deviation; the elastic swing design ensures that the raw material can be continuously and smoothly replenished without the need for frequent manual addition.

[0033] During operation, raw materials are placed into the feeding trough 4-4 and slide along the trough to the swinging sleeve block 4-3. The bending sleeve 3-4 pushes the raw materials to the forming trough 3-2, and the swinging sleeve block 4-3 swings to avoid them. After the pushing is completed, the swinging sleeve block 4-3 returns to its original position under the action of the spring, allowing new raw materials to be received. The elastic reset enables continuous feeding, and the push ensures precise guidance. The coordinated operation of all components enables continuous replenishment and precise pushing of raw materials, providing a reliable supply of raw materials for the continuous processing of the forming and processing component 3, and improving overall production efficiency.

[0034] For example, such as Figure 1 As shown, the clamping frame 3-7 has an overall U-shaped structure, and the top of both ends of the clamping frame 3-7 are sloping transition structures.

[0035] In some examples, the clamping bracket 3-7 has a U-shaped structure with its opening facing the flip plate 3-1. It can form a semi-enclosed fixation from both sides and the bottom of the flip plate 3-1. Compared with a flat fixing structure, this increases the contact area with the flip plate 3-1, improves the fixing stability, and prevents the flip plate 3-1 from shifting laterally when bent. The sloping transition structure at the top of the front two ends of the clamping bracket 3-7 can guide the clamping bracket 3-7 to smoothly fit against the flip plate 3-1 when it moves towards the flip plate 3-1, preventing sharp edges from scratching the surface of the flip plate 3-1 or hindering the movement of the clamping bracket 3-7.

[0036] For example, such as Figure 1 As shown, a conveyor belt 5 is provided at the bottom of the platform 1, and the conveyor belt 5 is located below the opening 2.

[0037] In some examples, the conveyor belt 5 at the bottom of the frame 1 is located below the opening 2, which can catch the formed U-shaped clamps falling from the opening 2, preventing the clamps from falling directly to the ground and causing collision damage, thus protecting the forming accuracy and appearance integrity of the clamps. Through continuous operation, the conveyor belt 5 can automatically transport the clamps to the subsequent collection or processing area, eliminating the need for frequent manual cleaning of the clamps below the opening 2, reducing manual intervention, and working in conjunction with the automatic unloading function of the tilting plate 3-1.

[0038] For example, such as Figure 1 As shown, the spacing between the uprights 4-1 and the height inside the notch 4-2 are matched with the length and diameter of the clamp material.

[0039] In some examples, the spacing between the uprights 4-1 and the height inside the notch 4-2 are matched with the length and diameter of the clamping material. The spacing between the uprights 4-1 is adapted to the length of the material, which can limit the displacement of the material in the lateral direction and prevent the material from being unable to accurately enter the forming groove 3-2 due to deviation in the length direction. The height of the notch 4-2 is adapted to the diameter of the material, which can ensure that the material is stably placed on the swing block 4-3 and avoid the material being unstable due to its small diameter or unable to be placed in the notch 4-2 due to its large diameter.

[0040] For example, such as Figure 3 As shown, the swing sleeve 4-3 can rotate a maximum of 90° to one side through the pin connection.

[0041] In some examples, the swing sleeve 4-3 can rotate a maximum of 90° to one side via a pin connection. This rotation angle limitation ensures that when the raw material is pushed, the swing sleeve 4-3 can swing downward at a sufficient angle to make room for the material to be conveyed, thus avoiding obstructing the material from moving to the forming groove 3-2. It also prevents the swing angle from being too large, which could cause the return spring 4-6 to be overstretched and damaged, or the swing sleeve 4-3 to collide with the bottom component of the frame 1.

[0042] In actual use: The U-shaped clamp material is placed into the feeding groove 4-4 of the upright 4-1 and the swing sleeve block 4-3 of the feeding assembly 4. The material slides along the feeding groove 4-4 onto the swing sleeve block 4-3, and the return spring 4-6 supports the swing sleeve block 4-3 to keep it horizontal. The forming processing assembly 3 is started, and the telescopic cylinder 3-6 on the side of the boss 3-5 drives the U-shaped clamping frame 3-7 to move towards the flip plate 3-1, and it fits and adheres to the flip plate 3-1 from both sides to complete the fixation. The horizontal linear drive on the side of the fixed seat 3-3 drives the bending sleeve 3-4 to slide towards the flip plate 3-1, pushing the material on the swing sleeve block 4-3 towards the flip plate 3-1. The swing sleeve block 4-3 swings downward around the pin axis to avoid the material, and the material is accurately pushed into the forming groove 3-2 of the flip plate 3-1. The bending sleeve 3-4 continues to move to bend the material into a U-shape. After forming, the telescopic cylinder 3-6 drives the clamping frame 3-7 to reset, and the electric drive rotates the tilting plate 3-1, aligning the forming groove 3-2 with the opening 2 of the frame 1. The U-shaped clamp falls through the opening 2 and is discharged into the conveyor belt 5 below under the action of gravity. At the same time, the tilting plate 3-1 switches to the next forming groove 3-2, and the swinging block 4-3 resets under the action of the return spring 4-6 to continue receiving new raw materials. The above process is repeated to achieve continuous processing.
