Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to an automatic tail nail cutting device. Background Technology

[0002] Tail pins are a common defect in stamping processes, especially in blanking or shearing operations. Due to factors such as improper die clearance, cutting edge wear, or material properties, the material may be stretched or torn before it completely breaks, resulting in small and protruding metal nail-like objects on the edge of the part.

[0003] The presence of tail screws and rivets not only affects the product's appearance but can also reduce assembly precision and performance, thus requiring their removal. Traditional removal methods typically involve operators using pliers, needle-nose pliers, or tweezers to grasp the exposed tail screw and repeatedly bend it until it breaks due to metal fatigue. However, this method has significant drawbacks: the bending process easily damages the substrate edges, resulting in missing material or protrusions, requiring subsequent finishing with files, scrapers, and other tools. Overall, traditional processes are inefficient and cannot meet the demands of high-quality and high-efficiency production. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides an automatic tail nail cutting device with high working efficiency.

[0006] The top surface of the conveyor plate is provided with a pressing device, which is used to fix the processed parts in the directional conveying trough; a positioning plate is provided on the side of the conveyor plate away from the discharge trough, which is used to position the processed parts in the directional conveying trough, and a tail removal machine is provided on the positioning plate.

[0007] Furthermore, the conveyor plate includes a flat portion and an inclined portion, the flat portion and the inclined portion being rotatably connected, and the mounting frame is provided with a driver A, which is used to adjust the tilt angle of the inclined portion.

[0008] Furthermore, the clamping device is provided in two parts, located on the top surface of the planar part and the inclined part, respectively.

[0009] Furthermore, the clamping device includes a driver B and a pressure plate connected to the output shaft of the driver B.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4 As shown, an automatic tail nail cutting device includes a mounting frame 1 and a feeding tray 2.

[0026] like Figure 1 As shown, the feeding tray 2 has an inclined discharge plate extending outwards, and the discharge plate is provided with a discharge trough 21, which includes a main trough and several branch troughs; the mounting frame 1 is provided with a conveying plate 4, and the top surface of the conveying plate 4 is provided with a directional conveying trough, which corresponds to and communicates with the branch troughs. The top surface of the conveying plate 4 is provided with a clamping device 3, which is used to fix the processed parts in the directional conveying trough.

[0027] like Figure 2 As shown, a positioning plate 5 is provided on the side of the conveyor plate 4 away from the discharge chute 21. The positioning plate 5 is used to hold the workpiece at the end of the conveyor plate 4 to prevent the workpiece in the positioning output shaft from slipping, and also to position the workpiece at the end of the conveyor plate 4 for subsequent processing. In this embodiment, a tailing machine 6 is also provided on the positioning plate 5.

[0028] like Figure 1 As shown, the top surface of the mounting frame 1 is connected to a loading trough 7 by screws, and the loading trough 7 is located at the bottom of the inclined part 42. The mounting frame 1 is also provided with a slag discharge hole 8, and the slag discharge hole 8 and the loading trough 7 are located on both sides of the positioning plate 5, respectively.

[0029] like Figure 2 As shown, the conveyor plate 4 includes a flat portion 41 and an inclined portion 42, wherein the flat portion 41 is horizontally arranged, and the inclined portion 42 is inclined downwards. In this embodiment, the flat portion 41 and the inclined portion 42 are rotatably connected, and the specific connection structure can be a hinge structure or a pivot connection structure. Figure 2As shown, a driver A43 is connected between the inclined portion 42 and the mounting bracket 1. The driver A43 is a telescopic cylinder, and the telescopic end of the telescopic cylinder is connected to the inclined portion 42. In addition, it should be noted that the length of the inclined portion 42 in this embodiment is the same as the length of a workpiece, that is, only one row of workpieces can be placed on the inclined portion 42.

[0030] When the telescopic cylinder extends outward, it pushes the inclined part 42 toward the positioning plate 5, reducing the tilt angle of the inclined part 42. At the same time, it causes the workpiece on the inclined part 42 to abut against the positioning plate 5, making it easier for the subsequent clamping device 3 to press and fix the workpiece on the inclined part 42, and the tail screw is removed by the tail removal machine 6.

[0031] When the telescopic cylinder retracts, it pulls the inclined part 42 away from the positioning plate 5, creating a moving space between the inclined part 42 and the positioning plate 5. At the same time, as the tilt angle of the inclined part 42 increases, the workpiece automatically slides down from the positioning conveying groove under the action of gravity and falls into the loading groove 7 from the formed moving space.

[0032] It is important to note that, such as Figure 2 As shown, when the telescopic cylinder extends outward, the inclined part 42 in this embodiment still has a certain gap with the positioning plate 5, which facilitates the waste chips formed by cutting the workpiece to enter the slag discharge hole 8 through the gap, so as to realize the automatic separation of finished product and waste chips.

[0033] like Figure 3 As shown, the clamping device 3 in this embodiment has two parts, located on the top surfaces of the flat portion 41 and the inclined portion 42, respectively. Specifically, the clamping device 3 includes a driver B31 and a pressure plate 32 connected to the output shaft of the driver B31. The bottom of the pressure plate 32 has a locking protrusion, which is adapted to the shape and size of the positioning conveying groove. The driver B31 drives the pressure plate 32 to move up and down, thereby pressing the pressure plate 32 against the workpiece on the flat portion 41 or the inclined portion 42, thus fixing the workpiece. To prevent the surface of the workpiece from being scratched, a soft pad can be added to the bottom of the pressure plate 32 in this embodiment. This soft pad can be fixed by adhesive and serves as the direct contact interface with the workpiece.

[0034] In this embodiment, both the positioning plate 5 and the tail-removing machine 6 are inclined, with the tail-removing machine 6 fixed to the positioning plate 5. The tail-removing machine 6 in this embodiment includes a driver C61 and a cutter 62. The cutter 62 is positioned in the hollow center of the positioning plate 5, and the driver C61 is fixed to the top of the positioning plate 5, with its output shaft passing through the positioning plate 5 and connected to the cutter 62. It should be noted that in this embodiment, the center positions of the cutter 62 and the positioning plate 5 are not on the same vertical plane to facilitate the operation of the cutter 62.

[0035] In this embodiment, the driver B31 and driver C61 can be a motor or a cylinder.

[0036] The working process of the automatic tail screw cutting device in this embodiment is as follows:

[0037] Sorting: The workpieces are sorted in the feeder so that the side with the tail stud is at the back and the side without the tail stud is at the front; after sorting, the workpieces enter the discharge plate and enter different positioning conveyor troughs from different branch troughs by gravity.

[0038] Pushing onto the flat section 41 and fixing it: It should be noted that the workpiece can not only slide down automatically under the action of gravity, but also push other workpieces in the positioning conveyor groove forward. When the workpiece is pushed onto the flat section 41 and is about to enter the inclined section 42, it will be pressed down by the clamping device 3 on the flat section 41 until the previous workpiece on the inclined section 42 is processed.

[0039] Advance to the inclined section 42 and positioning: After the previous workpiece is processed, the clamping device 3 on the flat section 41 moves upward, and the workpiece released by it is pushed forward by the subsequent workpiece and enters the inclined section 42. At this time, the telescopic cylinder is in the extended state, and the inclined section 42 is in a close position with the positioning plate 5. With the thrust of the subsequent workpiece, the tail pin part of the workpiece on the inclined section 42 abuts against the positioning plate 5, and the workpiece is positioned.

[0040] Fixing and cutting: After the workpiece is positioned, the clamping device 3 on the flat part 41 fixes the workpiece at its end. The clamping device 3 on the positioning plate 5 also presses and fixes the workpiece on the inclined part 42. Then the driver C61 drives the cutter 62 to move down and cut off the tail needle on the workpiece. The waste generated falls from the gap between the inclined plate and the positioning plate 5 onto the slag outlet 8 under the action of gravity.

[0041] Finished product release and collection: After the tail needle on the processed part is cut off to form a finished product, the clamping device 3 on the inclined part 42 moves upward to release the finished product at its bottom. At the same time, the telescopic cylinder retracts, and the finished product slides down from the moving space formed between the inclined part 42 and the positioning plate 5 under the action of gravity and falls into the loading trough 7.

[0042] Subsequently, the telescopic cylinder extends again. When the inclined part 42 and the positioning plate 5 are in a similar state, the clamping device 3 on the flat part 41 rises and releases the workpiece to be processed on the flat part 41. The workpiece to be processed enters the inclined part 42 again under the thrust of the subsequent workpiece to complete the positioning, fixing, cutting and finished product release and collection actions, and so on.

[0043] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
