Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a feeding device for stamping equipment. Background Technology

[0002] A punch press is a widely used machining equipment that uses dies to stamp metal sheets, achieving processes such as punching, blanking, and stretching. In the production of condenser fins, the fins are usually long, requiring punching of the entire workpiece. Multiple workpieces with aligned holes are then stacked and inserted into the tube to form the final product. However, due to the long length of the fins, using a single-pass punching machine is too bulky and costly, making it uneconomical. Therefore, a multi-pass punching method is used. However, during punching, the long workpieces tend to sag, leading to inaccurate hole alignment; furthermore, the workpieces are randomly stacked during blanking, making subsequent hole alignment cumbersome and reducing production efficiency. Utility Model Content

[0018] Figure 1 This is a schematic diagram of the structure of one embodiment of the present utility model;

[0019] Figure 2This is a schematic diagram of the adsorption state of a vacuum adsorption device according to an embodiment of the present invention. Detailed Implementation

[0020] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0021] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0023] An embodiment of this utility model provides a feeding device for a stamping equipment, such as... Figure 1-2 As shown, it includes:

[0024] Vacuum adsorption device 2 is installed on one side of the discharge end of punch press 1 and is used to adsorb workpiece 4 in continuous punching operation.

[0025] The unloading device 3 is located below the vacuum adsorption device 2. The unloading device 3 includes a base 301, a positioning structure 302 for placing the workpiece 4 on the base 301, and a moving structure 303 for driving the base 301 to move. The base 301 can move to or from below the vacuum adsorption device 2 under the drive of the moving structure 303.

[0026] Specifically, the punching operation of workpiece 4 involves punching holes row by row. During the punching process, a step-like conveyor structure is provided at the discharge end of the punch press 1. Typically, a feeding device and the punch press die work together. After the punch press 1 punches the workpiece once, the conveyor structure pushes the workpiece a certain distance towards the discharge end according to the set step distance, allowing the workpiece to enter the next punching position. Thus, workpiece 4 gradually moves outward at the discharge end as the punching operation continues. Because workpiece 4 is relatively long, a vacuum adsorption device 2 is provided on one side of the discharge direction. This device can adsorb workpiece 4 in real time during continuous punching operations through vacuum adsorption, preventing workpiece 4 from falling or shifting during the punching process and ensuring the continuity of the punching operation. The unloading device 3 is used to collect the completed workpiece 4. Since the subsequent assembly structure consists of multiple workpieces 4 stacked and inserted into the holes of the overlapping workpieces 4, the positioning structure 302 of the unloading device 3 can accurately position and collect the punched workpieces 4 according to the hole positions, reducing the sorting steps in subsequent processing and accelerating production speed. The moving structure 303 of the unloading device 3 can drive the base 301 to move to or from below the vacuum adsorption device 2, which facilitates the overall transfer of the filled workpiece 4 and allows the customer to unload it directly by means of forklifts, without being restricted or affected by the upper vacuum adsorption device 2. This improves the overall production efficiency, and workers do not need to contact the workpiece 4 being punched, thus solving the risk of safety accidents caused by improper operation.

[0027] In some embodiments, such as Figure 1 As shown, the positioning structure 302 includes multiple positioning seats 304 fixed on the base 301 and multiple positioning parts 305 disposed on the positioning seats 304. The positioning parts 305 are used to limit the unloading position of the workpiece 4.

[0028] This achieves precise positioning and stable collection of workpiece 4, ensuring that workpiece 4 will not shift position or accumulate randomly during the unloading process, thereby improving the accuracy and efficiency of unloading.

[0029] Furthermore, such as Figure 1-2 As shown, the positioning seat 304 is provided with a plurality of first positioning grooves corresponding to the hole positions of the workpiece 4, and the positioning part 305 includes a plurality of positioning rods 306 that can be inserted into the holes of the workpiece 4, with the bottom of the positioning rods 306 inserted into and fixed in the first positioning groove.

[0030] By cooperating with the first positioning groove, the positioning rod 306 can quickly position and stably support the hole of the workpiece 4, ensuring the uniform position of each workpiece 4 when it is unloaded. Furthermore, the positioning seat 304 is detachable and replaceable, which improves the versatility and adaptability of the unloading device 3 and can meet the needs of workpieces 4 with holes of different shapes and sizes.

[0031] Furthermore, such as Figure 1 As shown, the positioning rod 306 includes a guide portion 307 located at its top, which guides the hole on the workpiece 4 to align with the positioning rod 306 so that the positioning rod 306 is inserted into the hole on the workpiece 4.

[0032] Specifically, the diameter of the guide part 307 gradually decreases from bottom to top, and the top end can effectively guide the workpiece 4 to be quickly and accurately inserted into the positioning rod 306, ensuring that the workpiece 4 is smoothly aligned during the unloading process.

[0033] Furthermore, such as Figure 1 As shown, the positioning structure 302 includes multiple limiting seats 309 disposed above the positioning seat 304. The limiting seat 309 is provided with multiple second positioning grooves that are opposite to the first positioning groove. The positioning rod 306 passes through the second positioning groove, inserts downward and is fixed in the first positioning groove.

[0034] The positioning grooves of the upper and lower positioning seats 304 and the limiting seat 309 cooperate with each other to form a two-layer base, which can provide a more stable fixing effect for the positioning rod 306, prevent shaking, and enhance the firmness and reliability of the entire positioning structure 302.

[0035] Furthermore, such as Figure 1 As shown, the positioning part 305 also includes a limiting rod 311 disposed on the outside of the positioning rod 306. The limiting rod 311 is used to limit the position of the workpiece 4 on both sides.

[0036] To ensure that the hole of workpiece 4 falls smoothly at the positioning rod 306, the size of the positioning rod 306 will be smaller than the hole diameter, and workpiece 4 will have floating error. The setting of the limiting rod 311 directly limits the outer contour, realizing the dual limiting function of the positioning rod 306 and the limiting rod 311, and realizing the neat collection of workpiece 4 after unloading.

[0037] In some embodiments, such as Figure 1 As shown, the positioning structure 302 also includes an adjustment structure 312 for adjusting the position of the positioning seat 304. The base 301 is provided with an adjustment groove 313 arranged along the discharge direction of the workpiece 4 to cooperate with the adjustment structure 312. The positioning seat 304 can adjust its position back and forth in the adjustment groove 313 through the adjustment structure 312.

[0038] The adjustment structure 312 can flexibly adjust the position of the positioning seat 304 according to the size and shape of the workpiece 4 to adapt to workpieces 4 of different specifications. Furthermore, the positioning seat 306 can be replaced to further improve the versatility and flexibility of the feeding device 3.

[0039] Furthermore, such as Figure 1As shown, the adjustment structure 312 includes an L-shaped clamping block 314 and a fastener 315 fixed to the positioning seat 304. The lower part of the clamping block 314 is inserted into the adjustment groove 313, and the upper part of the clamping block 314 clamps and fixes the positioning seat 304 and the base 301 by the fastener 315.

[0040] The shape of the L-shaped clamping block 314 facilitates insertion and fixation within the adjustment groove 313. The fastener 315 connects the positioning seat 304 and the L-shaped clamping block 314, so that the positioning seat 304 is clamped onto the base 301, achieving rapid positioning and fixation.

[0041] In some embodiments, such as Figure 1 As shown, the moving structure 303 includes a moving guide rail 316 arranged in a direction perpendicular to the discharge direction of the workpiece 4, and a driving structure for driving the base 301 to move along the moving guide rail 316. The bottom of the base 301 is provided with a groove that cooperates with the moving guide rail 316.

[0042] The hydraulic cylinder, drive motor and other drive structures move under the guidance of the moving guide rail 316 through the control base 301, so that the control base 301 can move accurately to or from under the vacuum adsorption device 2, thereby realizing the movement of the workpiece 4 after unloading without being restricted or affected by the vacuum adsorption device 2.

[0043] Furthermore, the vacuum adsorption device 2 includes a pipeline structure, a vacuum adsorption plate 201 for adsorbing workpiece 4 located at the end of the pipeline structure, a vacuum pump connected to the pipeline structure, and a pressure relief plate 202 connected to the outside world located on the pipeline structure. The vacuum pump continuously draws a vacuum, enabling the vacuum adsorption structure 201 to directly and continuously adsorb the workpiece 4 during the punching operation, ensuring the stability and reliability of the adsorption process. After the workpiece 4 is processed, the pressure relief plate 202 is opened to connect the pipeline structure to the outside world and air is drawn from the pressure relief plate 202, which greatly reduces the suction force of the vacuum adsorption plate 201, causing the workpiece 4 to fall downwards.

[0044] The terms and words used in the foregoing description and claims are not limited to their literal meaning, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
