Description

Technical Field

[0001] This utility model relates to the field of sheet metal bending machines, and more specifically, it relates to an automatic feeding mechanism for sheet metal bending machines. Background Technology

[0002] Sheet metalworking is a comprehensive cold working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming. Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries, often used in assembly. Sheet metal parts are products manufactured using sheet metal processes, and they are indispensable in our daily lives. Sheet metal parts are made through processes such as filament power winding, laser cutting, heavy-duty machining, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending, die forging, and water jet cutting. Sheet metal parts are characterized by their light weight, high strength, electrical conductivity, low cost, and good mass production performance, and are widely used in electronics, communications, automotive, and medical device industries. Sheet metal parts are an essential component.

[0003] Some sheet metal parts require bending during manufacturing to shape them into the required form. In the current technology, most sheet metal parts are manufactured by workers grabbing the sheet metal parts and bending them on a sheet metal bending device. However, manual operation is dangerous and inefficient. In addition, manual feeding is difficult to ensure the accuracy of feeding, which can easily cause personal injury and lacks safety, making it difficult to meet the needs of industrialized production.

[0006] The present invention is further configured such that: the ends of the first and second hydraulic push rods are each connected to a push block; the first and second hydraulic push rods are configured to fix the sheet metal so that it moves sequentially on the first, second and third bending tables; and a baffle is provided above the first hydraulic push rods, the baffle being configured to prevent damage to the first hydraulic push rods when the sheet metal enters the bending assembly.

[0007] The present invention is further configured such that: the bending assembly includes a first bending table, a second bending table and a third bending table arranged sequentially on the workbench, and the first, second and third bending tables are each provided with a first groove, a second groove and a third groove respectively, the radii of the first, second and third grooves increase sequentially and cooperate with the clamping device to make the sheet metal bending achieve the preset effect in sequence.

[0008] The present invention is further configured such that: the conveying mechanism includes a feeding device on one side of the workbench and a discharging device on one side of the bending assembly; the discharging device includes a mounting platform on one side of the bending assembly, a telescopic rod on the mounting platform for pushing the processed sheet metal, and a moving block on one end of the telescopic rod that matches the bending assembly.

[0009] The present invention is further configured such that: the feeding device includes a feeding port disposed on one side of the machine housing and a conveying assembly for conveying sheet metal, the conveying assembly including two frames flush with the height of the feeding port, a plurality of conveying rollers disposed between the frames and a drive motor for driving the conveying rollers.

[0010] The present invention is further configured such that: the end of the conveying roller is provided with a transmission wheel, and is connected to the drive motor via a conveyor belt.

[0011] The present invention is further configured such that: the frame is symmetrically provided with adjusting blocks, and the adjusting blocks are configured to adjust the sheet metal to a suitable position to enter the bending assembly when the conveyor roller conveys the sheet metal.

[0012] The present invention is further configured such that: a discharge port is provided on the side of the housing away from the moving block, a collection box is provided below the discharge port, and an arc plate is provided between the collection box and the bending assembly.

[0013] The beneficial effects of this utility model are:

[0014] 1. On the workbench, the bending mechanism and the conveying mechanism work together. A protective housing surrounds the bending mechanism, ensuring operational safety and reducing external interference. The bending components are detachably connected to the workbench for easy maintenance and upgrades. The upper clamping device, through a combination of a fixed frame, hydraulic press, double-sided hydraulic push rods, and a specially designed clamping plate, ensures the precision and stability of the bending process. Particularly noteworthy is the sliding device on the fixed frame, which gives the clamping device flexible reciprocating motion capabilities, allowing it to adapt to diverse sheet metal processing needs, significantly improving production efficiency and reducing process changeover time. Furthermore, the safety housing and the precise clamping device together enhance operational safety and product quality.

[0015] 2. In the automatic feeding mechanism of this sheet metal bending machine, the ends of both sets of first and second hydraulic push rods are connected to push blocks. A baffle is provided above the first hydraulic push rod to prevent damage when the sheet metal enters the bending assembly. These four hydraulic push rods have important configuration functions; they can stably fix the sheet metal part and guide it to move sequentially between the first, second, and third bending tables, ensuring the orderly progress of the bending process. The bending assembly is specifically composed of the first, second, and third bending tables, which are sequentially set on the worktable. Each bending table is carefully designed with corresponding grooves, namely the first, second, and third grooves. It is worth noting that the radii of these three grooves increase sequentially. They cooperate with the clamping device above, allowing the sheet metal part to bend gradually as it passes through each bending table to achieve the pre-set ideal effect, thereby accurately completing the bending process of the entire sheet metal part.

[0016] 3. The conveying mechanism comprises two parts: a feeding device and a discharging device. The feeding device, located on one side of the worktable, is responsible for conveying the sheet metal parts to the processing position. The discharging device, situated on one side of the bending assembly, has a specific structure. It includes a mounting platform on one side of the bending assembly, equipped with a telescopic rod that pushes the processed sheet metal. At one end of the telescopic rod is a moving block that matches the bending assembly. The telescopic rod's extension and retraction moves the moving block, thus pushing the bent sheet metal part outward. A discharge port is located on the side of the machine housing furthest from the moving block, facilitating the output of the processed sheet metal parts. A collection box is placed below the discharge port to collect the sheet metal parts exiting from the discharge port. Furthermore, an arc-shaped plate is installed between the collection box and the bending assembly. This arc-shaped plate guides the sheet metal parts from the bending assembly, allowing them to slide smoothly into the collection box, ensuring a more efficient and orderly discharging and collection process.

[0017] 4. The feeding device includes a feed inlet located on one side of the machine housing, which is the entry point for the sheet metal parts into the equipment, and a conveying assembly responsible for transporting the sheet metal. The conveying assembly consists of several key parts: two frames flush with the feed inlet, which provide support; and several conveyor rollers positioned between these frames. These conveyor rollers are crucial for the smooth transport of the sheet metal and are driven by a drive motor. The ends of the conveyor rollers are equipped with drive wheels, which are connected to the drive motor via a conveyor belt to achieve power transmission, allowing the conveyor rollers to rotate stably and continuously transport the sheet metal forward. Furthermore, symmetrical adjusting blocks are arranged on the two frames. These adjusting blocks have an important configuration function; when the conveyor rollers transport the sheet metal, the adjusting blocks can precisely adjust it to the appropriate position, ensuring it accurately enters the bending assembly and prepares for subsequent bending operations, guaranteeing the smooth progress of the entire sheet metal processing flow.

[0021] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0022] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0023] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0024] like Figures 1 to 2 The automatic feeding mechanism of a sheet metal bending machine shown includes a worktable 16. The worktable 16 is equipped with a bending mechanism for bending sheet metal and a conveying mechanism for conveying sheet metal. A housing is fitted over the bending mechanism on the worktable 16. The bending mechanism and the conveying mechanism work together. A protective housing surrounds the bending mechanism, ensuring operational safety and reducing external interference. The bending mechanism includes a detachably connected bending component mounted on the worktable 16 and a clamping device positioned above the bending component, facilitating maintenance and upgrades. The clamping device includes a fixed frame 1 mounted on the worktable 16 and a clamping device mounted on the fixed frame 1. The system includes a hydraulic press 11, two sets of first hydraulic push rods 15 and second hydraulic push rods 4 symmetrically arranged on both sides of the bending assembly, and a clamping plate 3 located at the end of the hydraulic press 11 and matching the bending assembly. The fixed frame 1 is also equipped with a sliding device 2 for driving the clamping device to reciprocate within the bending assembly, ensuring the accuracy and stability of the bending process. The sliding device 2 on the fixed frame 1 gives the clamping device flexible reciprocating motion capability, enabling it to adapt to diverse sheet metal processing needs, greatly improving production efficiency and reducing process changeover time. Furthermore, the safety protective housing and the precise clamping device together improve operational safety and product quality.

[0025] Both sets of first and second hydraulic push rods are equipped with push blocks 28 at their ends. The first and second hydraulic push rods are configured to fix the sheet metal so that it moves sequentially on the first, second, and third bending tables. The ends of the first hydraulic push rod 15 and the second hydraulic push rod 4 are both connected to push blocks 28. A baffle 27 is provided above the first hydraulic push rod 15. The baffle 27 is configured to prevent damage to the first hydraulic push rod 15 when the sheet metal enters the bending assembly. These four hydraulic push rods have important configuration functions. They can stably fix the sheet metal parts and guide the sheet metal parts sequentially on the first bending table 10 and the second bending table. The bending assembly includes a first bending table 10, a second bending table 9, and a third bending table 8, which are sequentially arranged on the worktable 16. Each bending table is carefully designed with corresponding grooves, namely the first groove 14, the second groove 13, and the third groove 12. The radii of these three grooves increase sequentially. They cooperate with the clamping device above to allow the sheet metal parts to bend gradually to achieve the preset ideal effect when passing through each bending table, thereby accurately completing the bending process of the entire sheet metal parts.

[0026] The conveying mechanism comprises two parts: a feeding device and a discharging device. The feeding device is located on one side of the worktable 16 and is responsible for conveying the sheet metal parts to the processing position. The discharging device is located on one side of the bending assembly and has a specific structure. It includes a mounting platform 7 located on one side of the bending assembly. The mounting platform 7 is equipped with a telescopic rod 6 that can push the processed sheet metal. A movable block 5 matching the bending assembly is also provided at one end of the telescopic rod 6. The telescopic rod 6 moves the movable block 5, thereby pushing the bent sheet metal parts outward. A discharge port 24 is provided on the side of the machine housing away from the movable block 5, facilitating the output of the processed sheet metal parts. A collection box 26 is placed below the discharge port 24 to collect the sheet metal parts exiting from the discharge port 24. Furthermore, an arc-shaped plate 25 is provided between the collection box 26 and the bending assembly. This arc-shaped plate 25 can play a guiding role, allowing the sheet metal parts coming from the bending assembly to slide more smoothly into the collection box 26, ensuring that the entire material discharge and collection process is more efficient and orderly.

[0027] The feeding device includes a feed inlet 18 located on one side of the machine housing, which is the entry point for the sheet metal parts into the equipment, and a conveying assembly responsible for conveying the sheet metal. The conveying assembly consists of several key parts, including two frames 21 that are flush with the feed inlet 18, which provide support. Several conveying rollers 20 are arranged between these two frames 21. These conveying rollers 20 are key components for achieving stable sheet metal conveying and are equipped with a drive motor 22 to drive the conveying rollers 20 for transmission. The ends of the conveying rollers 20 are equipped with drive wheels 23, which are connected to the drive motor 22 by a conveyor belt to achieve power transmission, allowing the conveying rollers 20 to rotate stably and continuously convey the sheet metal forward. In addition, adjusting blocks 19 are symmetrically arranged on the two frames 21. These adjusting blocks 19 have an important configuration function. When the conveying rollers 20 convey the sheet metal, the adjusting blocks 19 can play a precise adjustment role, adjusting the sheet metal to the appropriate position to ensure that it can accurately enter the bending assembly, preparing for subsequent bending operations and ensuring the smooth progress of the entire sheet metal processing process.
