Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically to a punching device for metal products. Background Technology

[0002] A metal punching machine is a mechanical device that uses a punching die to punch holes in metal products under the drive of a power mechanism. Punching machines can perform stamping, die pressing, and embossing operations on thin sheet metal products.

[0003] Traditional punching devices have certain limitations. First, during operation, the metal material to be processed needs to be placed manually, and after the punching operation is completed, the processed product also needs to be removed manually. This method is not only inefficient and increases the time cost in the workflow, but also greatly increases the danger of manual operation because the operator needs to directly participate in the machine's work cycle, which can easily lead to workplace accidents. Utility Model Content

[0004] To achieve the above objectives, the present invention provides the following technical solution: a punching device for metal products, comprising an operating table and two sets of punching components mounted on the operating table. The punching components include a frame, on which a punching cylinder is mounted and two auxiliary columns are inserted. The piston rod of the punching cylinder is fixed with a punching plate. The device is characterized in that it also includes a feeding component mounted on the operating table.

[0005] The feeding assembly includes a vertical plate and two sets of screw devices. A lifting plate is fixed to the moving end of the screw device. A top platform that passes through the operating table is fixed to the lifting plate. A pushing cylinder is installed on the vertical plate and a pushing block that is fixed to the piston rod of the pushing cylinder slides on it. An upper lifting cylinder is installed on one side of the pushing block. An adsorption plate located above the two sets of top platforms is fixed to the piston rod of the upper lifting cylinder.

[0006] Furthermore, the bottom of the operating table is fixed with two frames, the top platform is located inside the corresponding frame, and the top of the frame is fixed with multiple guide posts extending to the top of the operating table, the guide posts being distributed around the corresponding top platform.

[0007] Furthermore, a support plate is installed on the platform, and a discharge port is opened between the support plate and the platform on the transverse axis. A collection box is placed below the platform.

[0008] Furthermore, the support plate is provided with multiple adsorption ports distributed on both sides of the discharge port.

[0009] Furthermore, two protruding posts are fixed to the top of the bearing plate, and two sleeves are fixed to the bottom of the stamping plate, with the sleeves adapted to the protruding posts.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The punching device for this metal product uses a lead screw in the feeding assembly to lift the lifting plate, which in turn lifts the metal product to a suitable height via the top platform. Then, in conjunction with the pushing cylinder, the pushing block moves, and with the cooperation of the top cylinder, the suction plate can be driven to suction the metal product on the top platform and move it to the frame to complete the punching operation. Therefore, it can realize automated loading and unloading, thereby reducing manual intervention, improving worker safety, and increasing efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This embodiment of a punching device for metal products includes an operating table 1. Two sets of punching components 3 are installed on the table surface of the operating table 1, and a feeding component 4 is installed between the two sets of punching components 3. Two sets of lifting components corresponding to the corresponding punching components 3 are installed at the bottom of the operating table 1. The punching component 3 includes two sets of frames 31 fixed on the operating table 1. A stamping cylinder 36 is installed on the frame 31 and two auxiliary columns 37 are inserted through it. The piston rod of the stamping cylinder 36 is fixed with a stamping plate 38 opposite to the table surface of the frame 31.

[0018] In the above structure, stacked metal product shells can be placed into the lifting assembly, which then pushes the top metal product to a suitable position. The loading assembly then moves the top metal product to the shelf, where a stamping cylinder drives the stamping plate to complete the punching operation. Finally, the loading assembly removes the punched metal product. By combining the above operations, automatic loading and unloading can be achieved, thereby improving processing efficiency while reducing manual intervention and enhancing the safety of workers.

[0019] Among them, such as Figure 2 A support plate 32 is installed on the platform 31. A discharge port 35 is provided on the transverse axis of the support plate 32 on the side opposite to the platform 31. A collection box is placed below the platform 31. When the stamping plate is punched, the waste material can fall into the collection box through the discharge port for collection.

[0020] To further explain, the support plate 32 has multiple adsorption ports 34 distributed on both sides of the discharge port 35. The adsorption ports 34 are interconnected, and the support plate 32 is also connected to an external adsorption device. Therefore, when the feeding assembly moves the metal product onto the support plate, it simultaneously covers the adsorption ports. Then, in conjunction with the external adsorption device, the metal product can be adsorbed and positioned on the support plate, preventing displacement.

[0021] To further explain, protruding posts 33 are fixed on both the left and right sides of the top of the bearing plate 32, and two sleeves 39 are fixed on the bottom of the stamping plate 38, which are opposite to the protruding posts 33. The sleeves 39 are adapted to the protruding posts 33. When the product is placed on the bearing plate, the two protruding posts can limit the left and right sides. At the same time, when the stamping plate is pressed down, they can extend into the sleeves to avoid obstructing the downward pressure of the stamping plate. They also serve to lower the product during the pressing process, preventing damage to the bearing plate caused by excessive downward pressure.

[0022] like Figure 1 The lifting assembly includes two screw devices 21 installed at the bottom of the operating platform 1. A lifting plate 22 is fixed to the moving end of each screw device 21. A top platform 23, which passes through the operating platform 1, is fixed to the top of the lifting plate 22. The two top platforms 23 correspond to corresponding support platforms 31, with the length of the left top platform 23 being shorter than that of the right top platform 23. Therefore, two sets of metal products of different sizes can be stacked on the designated top platform. The operation of the screw devices causes the lifting plate to move the top platform upwards, positioning the metal products on top in an easily accessible position.

[0023] The operating platform 1 has two frames 24 fixed at its bottom, which surround the corresponding top platform 23. Multiple guide posts 25, distributed on the front and rear sides of the top platform 23, are fixed at the top of the frames 24. During the lifting and lowering of the top platform, the guide posts can surround the metal product, limiting its movement and improving stability.

[0024] like Figure 3 The loading assembly 4 includes a vertical plate 41 fixed to the operating table 1 and located between two support platforms 31. A pushing cylinder 42 is installed on the top of the vertical plate 41, and a pushing block 43, which is slidably fixed to the piston rod of the pushing cylinder 42, is installed on the right side of the pushing block 43. An upper-lifting cylinder 44 is installed on the piston rod of the upper-lifting cylinder 44, and an adsorption plate 45 located above the two sets of top platforms 23 is fixed thereon. By pushing the pushing block with the pushing cylinder, the adsorption plate can be moved in three positions: above the top platform, the support platform, and the outside. Therefore, with the cooperation of the upper-lifting cylinder, the adsorption plate can adhere and adsorb the two sets of metal products on the top platform and transfer them to the support plate. After punching is completed, the adsorption plate moves again to adsorb the metal products and move them to the other side of the top platform to put the products down, thereby realizing automatic loading and unloading and reducing manual intervention.
