Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to an intelligent stamping forming mold for automotive sheet metal parts. Background Technology

[0002] With the rapid development of the automotive industry, the demand for automotive parts is constantly increasing, and higher requirements are being placed on the quality, precision, and cost of these parts. As a key piece of equipment in the production of automotive sheet metal parts, the technical level and performance of stamping dies directly affect the quality and production efficiency of automotive products.

[0003] A document with publication number CN222999461U discloses a stamping die for automotive sheet metal parts, comprising: a mounting plate, a blanking assembly for blanking the stamped sheet metal parts, and an ejector assembly for ejecting the stamped sheet metal parts. The blanking assembly includes a fixed plate, a fixed rod, a rotating rod, and a lifting column. The fixed plate is fixedly connected to the fixed rod, the fixed rod is rotatably connected to the rotating rod, and the rotating rod abuts against the lifting column. When the cylinder drives the press to descend for stamping, the rotating rod remains stationary. When the cylinder drives the press to rise, the lifting column touches one end of the rotating rod, causing it to rotate around the fixed rod. This causes the other end of the rotating rod to scrape against the surface of the press, detaching the sheet metal parts adhering to the press surface, facilitating material removal by the operator.

[0004] When this device is in use, after pressing is completed, the presser rises, and the positioning rod rises accordingly. The sliding part at the bottom of the positioning rod contacts the bottom of the stamped sheet metal part, slightly lifting it so that it does not stick to the stamping table, making it easier for workers to remove. However, the contact between the sliding part and the sheet metal part may damage the surface of the sheet metal part, causing scratches and affecting product quality.

[0005] Therefore, it is necessary to provide an intelligent stamping die for automotive sheet metal parts to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an intelligent stamping forming mold for automotive sheet metal parts that can separate the sheet metal parts adsorbed in the forming groove from the forming groove without direct contact with the sheet metal parts.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The intelligent stamping forming mold for automotive sheet metal parts includes: a stamping table and a forming head installed above the stamping table. The forming head can be raised and lowered. A forming groove is opened on the top of the stamping table. A non-contact ejection mechanism is set on the stamping table. The non-contact ejection mechanism includes a buffer cavity opened inside the stamping table. Multiple connection holes are set between the buffer cavity and the forming groove. An air inlet pipe is installed on one side of the stamping table. The air inlet pipe is connected to the buffer cavity. One end of the air inlet pipe is connected to a high-pressure air source. A control valve is installed on the air inlet pipe.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0026] Example 1:

[0027] like Figure 1-3As shown, this utility model provides an intelligent stamping forming mold for automotive sheet metal parts, comprising: a stamping table 1 and a forming head 2 installed above the stamping table 1. The forming head 2 is movable, and a forming groove 3 is formed on the top of the stamping table 1. The forming groove 3 is designed according to the specific shape and size requirements of the automotive sheet metal parts, which will not be described in detail here. This embodiment only uses a hemispherical automotive sheet metal part as an example. The forming head 2 is located directly above the forming groove 3. To facilitate the removal of the sheet metal parts from the forming groove 3, a non-contact ejection mechanism is provided on the stamping table 1. The non-contact ejection mechanism includes a buffer cavity 4 opened inside the stamping table 1. Multiple connecting holes 5 are provided between the buffer cavity 4 and the forming groove 3. The diameter, number, and position of the connecting holes 5 should not affect the forming process of the sheet metal parts. A sufficiently large-diameter air inlet pipe 6 is installed on one side of the stamping table 1, connecting to the buffer chamber 4. One end of the air inlet pipe 6 is connected to a sufficient high-pressure air source, such as a large air pump or an air tank that can be easily replenished. A control valve 7 is installed on the air inlet pipe 6. The control valve 7 is a quick-opening valve, which can generally complete the opening and closing action within a few seconds. It should be noted that the control valve 7 does not need to reach 100% opening degree in actual operation. It is only necessary to provide sufficient high-pressure gas to the buffer chamber 4 in a short time to make the inside of the buffer chamber 4 positive pressure, which is sufficient to lift the sheet metal part in the forming groove 3. In use, the sheet metal part is placed on the forming groove 3, the forming head 2 descends to press the sheet metal into the forming groove 3 for forming, and then the forming head 2 rises to return to its original position. When control valve 7 is opened, a large amount of gas is injected into buffer chamber 4 through air inlet pipe 6 in a short time, creating positive pressure within buffer chamber 4. The high-pressure gas enters forming groove 3 through connection hole 5, impacting the bottom of the sheet metal part within forming groove 3, preventing the sheet metal part from adhering to it and facilitating its removal. Furthermore, as the airflow exits along the gap between forming groove 3 and the sheet metal part, the high-speed airflow's cooling effect lowers the sheet metal part's temperature, reducing the possibility of burns. This cooling effect is related to the airflow duration and speed, and can be adjusted according to the sheet metal part's temperature. If the sheet metal part is hot after stamping, the airflow duration can be extended, and the opening degree of control valve 7 can be increased; conversely, the airflow duration should be shortened, and the opening degree of control valve 7 reduced. It is worth noting that unused connection hole 5 can be sealed with a seal.

[0028] By setting a non-contact ejection mechanism including a buffer chamber 4, a connecting hole 5, an air inlet pipe 6, and a control valve 7 on the stamping table 1, the sheet metal parts adsorbed in the forming groove 3 can be separated from the forming groove 3 without direct contact with the sheet metal parts. This reduces damage to the sheet metal parts, improves the quality of the sheet metal parts, and allows for heat dissipation of the sheet metal parts, reducing the possibility of burns when personnel remove the sheet metal parts.

[0029] Example 2:

[0030] like Figure 2As shown, in this embodiment, a collection chamber is provided inside the stamping table 1, and a collection box 10 is placed inside the collection chamber. A sealing door 8 is installed on the outside of the collection chamber, and a conical guide hole 9 is provided at the bottom of the buffer chamber 4. The collection chamber and the buffer chamber 4 are connected through the guide hole 9. In use, after the sheet metal part is taken out from the forming groove 3, an air gun is used to clean the forming groove 3 by air jet. Some debris will enter the buffer chamber 4 through the connecting hole 5 and fall into the collection box 10 along the guide hole 9, thereby facilitating the collection of some debris generated during stamping and forming, which is convenient for subsequent processing.

[0031] By setting up a collection cavity, guide hole 9 and collection box 10, it is possible to conveniently collect some of the debris generated during stamping.

[0032] Example 3:

[0033] like Figure 1 As shown, in this embodiment, a top plate 11 is provided above the stamping table 1, and multiple guide columns 12 are installed between the top plate 11 and the stamping table 1. A lifting plate 13 is provided between the top plate 11 and the stamping table 1, and the lifting plate 13 is slidably connected to the guide columns 12. The forming head 2 is fixed at the bottom of the lifting plate 13. A hydraulic cylinder 14 is installed on the top plate 11, and the output end of the hydraulic cylinder 14 is fixedly connected to the lifting plate 13. When in use, the hydraulic cylinder 14 is started, causing its output shaft to extend, thereby driving the lifting plate 13 to descend. The descent of the lifting plate 13 drives the forming head 2 to descend, and vice versa, the forming head 2 rises.

[0034] By setting up a top plate 11, guide column 12, lifting plate 13, and hydraulic cylinder 14, the lifting and lowering of the forming head 2 can be easily driven.

[0035] Example 4:

[0036] like Figure 1 and Figure 3As shown, in this embodiment, a distance detection mechanism 15 is installed below the top plate 11. The distance detection mechanism is used to detect the distance between it and the lifting plate 13. The distance detection mechanism 15 and the control valve 7 are both connected to the same intelligent controller. The distance detection mechanism 15 measures the distance between itself and the lifting plate 13 at certain time intervals, such as 150ms, and sends the results to the intelligent controller. The intelligent controller automatically determines whether the lifting plate 13 is moving away from or approaching the top plate 11 according to the time sequence. When the intelligent controller determines that the lifting plate 13 is approaching the top plate 11, it sends a signal to the control valve 7 to open it, and the high-pressure gas enters the buffer chamber 4 through the air inlet pipe 6. Conversely, when the intelligent controller determines that the lifting plate 13 is moving away from the top plate 11, it sends a signal to the control valve 7 to close it, stopping the gas supply to the buffer chamber 4. It is worth noting that the opening time of the control valve 7 can also be lengthened or shortened by writing a signal delay transmission program. This is completely feasible for those skilled in the art and can be easily accomplished.

[0037] By installing a distance detection mechanism 15 below the top plate 11, the automatic opening and closing of valve 7 can be easily controlled, making the equipment more intelligent to use.

[0038] Example 5:

[0039] like Figure 1 As shown, in this embodiment, a safety detection device 16 is embedded and installed in the loading and unloading area of ​​the stamping table 1. The safety detection device 16 uses visual detection or infrared detection to intelligently determine whether a human body has passed through the loading and unloading area. If a human body has passed through, an alarm will be issued. This type of safety detection device 6 has been used in a large number of industrial processing equipment and security equipment. Its structure and principle will not be described in detail here.

[0040] By installing a safety detection device 16 in the loading and unloading area of ​​the stamping table 1, the safety of the equipment can be improved.

[0041] Working principle: During use, the sheet metal part is placed on the forming groove 3. The forming head 2 descends to press the sheet metal into the forming groove 3 for forming, and then the forming head 2 rises back to its original position. The control valve 7 opens, and a large amount of gas is injected into the buffer chamber 4 through the air inlet pipe 6 in a short time, creating positive pressure in the buffer chamber 4. The high-pressure gas enters the forming groove 3 through the connecting hole 5, impacting the bottom of the sheet metal part in the forming groove 3, causing the sheet metal part to no longer adhere to the forming groove 3. This makes it easier to remove the sheet metal part from the forming groove 3. Furthermore, since the airflow will exit along the gap between the forming groove 3 and the sheet metal part, the cooling effect brought by the high-speed airflow will reduce the temperature of the sheet metal part, thus reducing the possibility of burns.
