Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a hydraulic automatic stamping device. Background Art

[0002] A hydraulic automatic stamping device is a mechanical device used for metal processing. It utilizes the pressure and control functions provided by a hydraulic system to automatically complete the process of metal stamping.

[0003] During the process of high-frequency stamping of raw materials by a stamping device, the stamping die is very likely to heat up. An overheated stamping die may cause softening or deformation of the die material, thereby reducing the service life of the die, and even causing damage to the die, increasing the production cost and maintenance cost. In addition, overheating of the die may cause dimensional changes or shape distortion, thereby affecting the processing accuracy and dimensional stability of the product and reducing the quality standard of the product.

[0004] Therefore, it is necessary to design a hydraulic automatic stamping device to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a hydraulic automatic stamping device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A hydraulic automatic stamping device includes a stamping device. A slidable sliding frame is installed on the stamping device. A stamping die is installed on the sliding frame. A fixed frame is fixed on the sliding frame. A jet pipe is fixed on the fixed frame. A plurality of jet openings are formed in the jet pipe. A gas supply assembly is arranged on the stamping device.

[0008] As a preferred technical solution of the utility model, the gas supply assembly includes a connecting plate and two gas supply structures. The connecting plate is fixed on the sliding frame. The two gas supply structures are both arranged on the stamping device. Each gas supply structure includes a sealing cylinder, a sliding plug, a connecting rod, two air pipes and two one-way valves. The sealing cylinder is fixed on the stamping device. The sliding plug is hermetically and slidably connected to the inner surface of the sealing cylinder. One end of the connecting rod is fixedly connected to the sliding plug, and the other end extends to the outside of the sealing cylinder. The end of the connecting rod located outside the sealing cylinder is fixed on the connecting plate. One ends of the two air pipes are both communicated with the sealing cylinder. The two one-way valves are respectively installed on the two air pipes. The other end of one of the air pipes is communicated with the jet pipe.

[0012] As a preferred technical solution of the present utility model, the air pipe is made of a flexible pipe.

[0013] The present utility model has the following beneficial effects:

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Referring to Figure 1-2 , a hydraulic automatic stamping device includes a stamping device 1. A slidable sliding frame 2 is installed on the stamping device 1. A stamping die 3 is installed on the sliding frame 2. It is characterized in that a fixed frame 4 is fixed on the sliding frame 2, a jet pipe 5 is fixed on the fixed frame 4, a plurality of jet orifices 6 are formed on the jet pipe 5, a plurality of the jet orifices 6 are all arranged facing the stamping die 3, and a plurality of the jet orifices 6 are evenly distributed on the jet pipe 5;

[0020] An air supply assembly is provided on the stamping device 1. The air supply assembly includes a connecting plate 71 and two air supply structures. The connecting plate 71 is fixed on the sliding frame 2. Both of the two air supply structures are provided on the stamping device 1. Each air supply structure includes a sealing cylinder 72, a sliding plug 73, a connecting rod 74, two air pipes 75 and two one-way valves 76. The sealing cylinder 72 is fixed on the stamping device 1. The sliding plug 73 is sealingly and slidably connected to the inner surface of the sealing cylinder 72. One end of the connecting rod 74 is fixedly connected to the sliding plug 73, and the other end extends to the outside of the sealing cylinder 72. The end of the connecting rod 74 located outside the sealing cylinder 72 is fixed on the connecting plate 71. One ends of the two air pipes 75 are both communicated with the sealing cylinder 72. The air pipes 75 are made of flexible hoses to avoid the air pipes 75 hindering the normal movement of the sliding frame 2. The two one-way valves 76 are respectively installed on the two air pipes 75. The flow-limiting directions of the two one-way valves 76 located on the same sealing cylinder 72 are opposite. The other end of one of the air pipes 75 is communicated with the jet pipe 5. During the up-and-down movement of the sliding frame 2, the two sealing cylinders 72 can periodically supply air into the jet pipe 5, so that the gas continuously sprays out through the jet ports 6. Therefore, a plurality of jet ports 6 can continuously spray gas onto the stamping die 3, thereby playing a role in cooling the stamping die 3 and avoiding the phenomenon of overheating of the stamping die 3 during high-frequency stamping.

[0021] The specific working principle of the present utility model is as follows:

[0022] When the hydraulic automatic stamping equipment proposed by the present utility model is in use, the sliding frame 2 drives the stamping die 3 to move up and down to perform high-frequency stamping on raw materials. During the up and down movement of the sliding frame 2, the connecting plate 71 will also move up and down accordingly. When the connecting plate 71 moves downward, the connecting plate 71 can drive the two connecting rods 74 to move downward, and the two sliding plugs 73 will also move downward in the two sealing cylinders 72. When the connecting plate 71 moves upward, the connecting plate 71 can drive the two connecting rods 74 to move upward, and the two sliding plugs 73 will also move upward in the two sealing cylinders 72. Therefore, with the up and down movement of the sliding frame 2, the two sliding plugs 73 will move up and down in the two sealing cylinders 72. Since the current-limiting directions of the two one-way valves 76 on the same sealing cylinder 72 are opposite, specifically, one of the one-way valves 76 restricts the gas to only enter the sealing cylinder 72, and the other one-way valve 76 restricts the gas to only flow out of the sealing cylinder 72. Therefore, when the two sliding plugs 73 move downward synchronously, one of the sealing cylinders 72 can perform an air extraction action, and the other sealing cylinder 72 can perform an exhaust action. The exhaust sealing cylinder 72 can discharge the gas into the interior of the jet pipe 5, so that the gas is ejected through a plurality of jet ports 6. When the two sliding plugs 73 move upward synchronously, the sealing cylinder 72 that originally performed the air extraction action performs exhaust, and the sealing cylinder 72 that originally performed the exhaust action performs air extraction. In summary, during the up and down movement of the sliding frame 2, the two sealing cylinders 72 can periodically supply gas to the jet pipe 5, so that the gas is continuously ejected through the jet ports 6. Therefore, a plurality of jet ports 6 can continuously eject gas to the stamping die 3, thereby playing a role in cooling the stamping die 3 and avoiding overheating of the stamping die 3 during high-frequency stamping.

[0023] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
