Technical Field

[0001] The utility model relates to the technical field of stamping devices, in particular to a durable aluminum profile stamping device. Background Technique

[0002] Aluminum profile stamping refers to a forming processing method in which an external force is applied to an aluminum profile through a stamping die to cause plastic deformation or separation, so as to obtain a workpiece with the required shape and size. During the aluminum profile stamping process, the aluminum profile can be stamped into a specific shape by using a stamping die, such as a convex hole, a concave-convex curved surface, etc.

[0003] At present, there are mainly two stamping methods for the existing stamping devices for aluminum profile processing, namely point-to-point stamping (such as punching) and whole-surface stamping. Among them, during the whole-surface stamping process, a large impact force will be generated, which will cause a large shock to the entire device. Long-term vibration will cause shaking, loosening and micro-deformation of the mold, the connecting parts and the structure of the device, etc., which not only reduces the use stability and stamping effect of the stamping device, but also increases the later maintenance cost. Therefore, we need an optimized durable aluminum profile stamping device to solve the problems mentioned above. Content of the Utility Model

Specific embodiments

[0017] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0018] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of description, the sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the protection scope of the present utility model here. In addition, the three-dimensional spatial dimensions including length, width and depth should be included in the actual production.

[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Figures 1 - 3 Shown is a schematic diagram of the entire structure of a durable aluminum profile stamping device of the present utility model. Please refer to Figures 1 - 3 , A durable aluminum profile stamping device in this embodiment includes a base 100, a support frame 110 is fixed on the upper part of the base 100, a stamping die mounting plate 200 driven by a hydraulic device to move up and down is arranged on the upper inner side of the support frame 110, a positioning base 300 is fixedly installed at the upper end of the base 100, a plurality of guiding pin columns 310 are fixed around the top of the positioning base 300, a piston 320 is installed at the upper end of the guiding pin column 310, a lower die positioning seat 400 is horizontally arranged directly above the positioning base 300, the inner side of the lower die positioning seat 400 has a positioning groove 401 for installing a lower die, and a plurality of cylindrical cavities 403 that penetrate downward and correspond to and match the guiding pin columns 310 and the piston 320 are arranged on the inner sides around the lower die positioning seat 400, and an air inlet hole 404 communicating with a high-pressure air source is arranged at the upper end of the cylindrical cavity 403.

[0021] The bottom surface of the positioning groove 401 further has an avoidance groove 402 penetrating through the bottom of the lower die positioning seat 400, and the inner side of the positioning base 300 further has an avoidance groove 301 corresponding to the avoidance groove 402. It can be understood that the stamping die mounting plate 200 is used to mount the stamping die / stamping tool. The lower die positioning seat 400 can position and install the lower die for placing the aluminum profile through the positioning groove 401, and the stamping die mounting plate 200 and the lower die positioning seat 400 are vertically corresponding. In addition, since waste chips will be generated during hole stamping, the waste chips after stamping can be conveniently discharged directly downward through the cooperation of the avoidance groove 402 and the avoidance groove 301. Of course, the base 100 also has a discharge port corresponding to the upper avoidance groove. In other embodiments, a waste collection box can also be provided at the lower part of the base 100, which is not limited herein.

[0022] A T-shaped connecting rod 330 for fitting and installing the piston 320 is further fixed to the top of the guide pin column 310, and the diameter of the vertical end of the T-shaped connecting rod 330 is smaller than the diameter of the guide pin column 310. Here, on the one hand, vertical limit can be carried out between the positioning base 300 and the lower die positioning seat 400 through the cooperation of the guide pin column 310 and the cylindrical cavity 403, avoiding the side slip and offset of the lower die mechanism during stamping use; secondly, through the cooperation of the piston 320 and the cylindrical cavity 403, an air top cooperation is formed between the cylindrical cavity 403 and the guide pin column 310. Therefore, when the lower die positioning seat 400 is pressed downward by stamping, the positioning base 300 can form a vertical buffer for the lower die positioning seat 400 and the lower die through the guide pin column 310 and the cylindrical cavity 403, effectively preventing adverse vibrations from being caused to the lower die mechanism and the equipment due to excessive impact force, ensuring the durability stability and stamping effect during the use of the stamping device, and reducing the later maintenance cost.

[0023] It should be noted that the number of the guide pin columns 310 and the corresponding cylindrical cavities 403 can be set according to actual needs. The more the number, the greater the buffer support force, and vice versa.

[0024] An air pump 600 is further externally provided at the lower end of the abutment 100. The output end of the air pump 600 is connected to an air pipeline 610, and the air pipeline 610 is communicated with the air injection hole 404 through an externally connected electromagnetic valve, a pressure relief valve and an air guiding branch pipe. It can be understood that since the lower die positioning seat 400 will compress the upper air cavity section of the cylindrical cavity 403 when being impacted, during the compression process, a part of the compressed air pressure will be discharged through the air injection hole 404 and the pressure relief valve. After the stamping is completed, the air pump 600 will reinject air pressure into the upper air cavity of the cylindrical cavity 403 in cooperation with the air pipeline 610, the electromagnetic valve, the pressure relief valve and the air guiding branch pipe. In addition, an angle detector can be arranged on the lower die positioning seat 400. The purpose is that when the air pump 600 reinjects air pressure into the cylindrical cavity 403, the angle detector will sense in real time whether the lower die positioning seat 400 is in a horizontal lifting state, and uniform air injection into multiple cylindrical cavities 403 will be completed in cooperation with the electromagnetic valve and the control system.

[0025] A hydraulic cylinder 500 is further fixed at the upper end of the support frame 110, and the output rod end of the hydraulic cylinder 500 is connected to the upper part of the stamping die mounting plate 200. Two sides of the upper end of the stamping die mounting plate 200 are vertically fixed with guide columns 510, and the guide columns 510 vertically slide on the top of the support frame 110 through bushings. With the cooperation of the guide columns 510, the hydraulic cylinder 500 moves the stamping die mounting plate 200 up and down and stamping more stably, ensuring uniform stress on the profile blank and the lower die.

[0026] Furthermore, a sealing ring 410 which is fitted and sleeved on the outer peripheral side of the guide pin 310 is also embedded at the bottom edge of the cylindrical cavity 403. By arranging the sealing ring 410, it can prevent external dust from entering the inner cavity through the bottom opening of the cylindrical cavity 403, ensuring the normal use of the sliding mechanism.

[0027] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in the present invention can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
