[0002] In the automotive industry, the processing of auto parts is crucial to the quality and performance of the vehicle. As one of the key equipment for auto parts processing, presses are widely used in the manufacturing process of various auto parts.

[0003] At present, the existing auto parts presses play an important role in the processing process, but when processing thin-walled shell workpieces, some problems are prone to occur because the raw materials are easy-to-bend metal sheets. When performing stamping and other processing operations on such workpieces, due to the working characteristics of the press, when the upper punch moves downward to press the workpiece, the material at the edge is subjected to stress after the raw material is pressed. Under the influence and restriction of the pressure and the mold, the material at the edge will deform and bend upward, thereby completing the processing of the workpiece. This kind of workpiece shape with an upwardly bent edge occasionally has the edge of the workpiece stuck on the punch. Once the die jam occurs, it will not only affect the continuity of production, but also take time and manpower to handle, reducing production efficiency.

[0004] The existing technology has not solved the above problems well, which has brought troubles to the normal work in this field. Therefore, there is an urgent need for a press for processing automobile parts to solve the above problems. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Reference Figure 1 to Figure 8, which is the first embodiment of the present invention, proposes a press machine for processing automobile parts, including a frame 1, a lifting part 2, a pressing block 3, a bearing block 4 and an air supply unit 5, the lifting part 2 is lifted and slidably arranged on the frame 1, the pressing block 3 is arranged on the lifting part 2, the bearing block 4 is arranged on the frame 1, and the pressing block 3 and the bearing block 4 are used to place products between them. The pressing block 3 has a through blowing hole 6, and the air supply unit 5 is arranged on the frame 1. One end of the blowing hole 6 is connected to the air supply unit 5, and the other end is used to face the product. After the pressing block 3 rises, the air supply unit 5 supplies air to the blowing hole 6 for spraying air to the product.

[0027] In this embodiment, the frame 1 is a stable and reliable supporting structure of the entire press. The lifting part 2 is mounted on the frame 1 and can be lifted and slid, thereby driving the pressing block 3 to move up and down. The pressing block 3 is mounted on the lifting part 2. When the lifting part 2 descends, the pressing block 3 moves downward to process the product placed on the bearing block 4. The bearing block 4 is fixed on the frame 1 to provide support for the product.

[0028] A through blowing hole 6 is provided inside the pressing block 3, and the air supply unit 5 is also installed on the frame 1. One end of the blowing hole 6 is connected to the air supply unit 5, and the other end faces the product. When the product is processed, the lifting part 2 drives the pressing block 3 to move downward, and the pressing block 3 cooperates with the supporting block 4 to perform operations such as stamping on the product. When the processing is completed, the lifting part 2 rises, driving the pressing block 3 to leave the product. At this time, the air supply unit 5 starts to supply air to the blowing hole 6, and the air flow blows out from the blowing hole 6 and acts on the surface of the product. The air flow can help separate the product from the pressing block 3, prevent the edge of the product from being stuck on the pressing block 3, and ensure that the product is smoothly separated from the pressing block 3 and enters the next process.

[0029] First, the press effectively solves the problem of easy die jamming of thin-walled shell workpieces during processing by adding an air supply unit 5 and a blow hole 6. After processing is completed, when the pressing block 3 rises, the air supply unit 5 supplies air to the blow hole 6, and the airflow can help separate the product from the pressing block 3, avoiding the occurrence of die jamming and ensuring the continuity of production. Secondly, since die jamming is avoided, the time and manpower spent on dealing with the die jamming problem are reduced, and the production efficiency is greatly improved. At the same time, the press has a simple structure, is easy to operate, and is easy to realize automated production.

[0030] Furthermore, the air supply unit 5 includes a cylinder body 7, a piston body 8, a piston rod 9 and an air pipe 10. The cylinder body 7 is arranged on the frame 1. The cylinder body 7 has an air hole 11 and an air hole 2 12. Both ends of the air pipe 10 are respectively connected to the air hole 11 and the blowing hole 6. The piston rod 9 is slidably arranged on the cylinder body 7. The piston body 8 is arranged at one end of the piston rod 9. The piston body 8 is located in the cylinder body 7 and between the air hole 11 and the air hole 2 12.

[0031] Furthermore, it also includes a connecting plate 13, which is arranged on the lifting part 2, and one end of the piston rod 9 extending out of the cylinder body 7 is arranged on the connecting plate 13, and the air hole 1 11 is located above the air hole 2 12.

[0032] In this embodiment, during the working process, when the product is processed, the lifting part 2 drives the pressing block 3 to move downward. Due to the connection of the connecting plate 13, the piston rod 9 also moves downward, thereby driving the piston body 8 to move downward in the cylinder body 7. At this time, the piston body 8 squeezes the air in the cylinder downward, the air hole 11 enters the air, and the air hole 2 12 is discharged, and the air is directly discharged to the outside from the air hole 2 12. When the processing is completed, the lifting part 2 rises, driving the pressing block 3 to move upward. Similarly, through the connection of the connecting plate 13, the piston rod 9 and the piston body 8 also move upward. At this time, the piston body 8 squeezes the air in the cylinder upward, the air hole 11 is discharged, and the air hole 2 12 is inlet, and the air is discharged from the air hole 11 to the air pipe 10, and then finally discharged to the blowing hole 6 on the pressing block 3 through the air pipe 10. The airflow blown out from the blowing hole 6 acts on the surface of the product, helping the product to separate from the pressing block 3 and preventing the edge of the product from being stuck on the pressing block 3.

[0033] First, through this special design of the air supply unit 5, the lifting and lowering of the briquette 3 and the linkage with the air supply are realized, and no additional power source is required to drive the air supply unit 5, saving energy and equipment costs. Secondly, this linkage design makes the air supply more timely and accurate. When the briquette 3 rises, an air flow is immediately blown out from the blowing hole 6 to act on the surface of the product, which greatly improves the efficiency and reliability of product separation. Furthermore, the entire air supply unit 5 has a compact structure and does not take up too much space, which is convenient for the overall layout and installation of the press. Finally, this design improves the degree of automation of the press, reduces manual intervention, and further improves production efficiency.

[0034] Furthermore, the pressing block 3 has a male mold portion 14, and the supporting block 4 has a female mold portion 15, the male mold portion 14 and the female mold portion 15 are matched in shape, the pressing block 3 and the lifting portion 2 are detachably connected, and the supporting block 4 and the frame 1 are detachably connected.

[0035] In this embodiment, since the pressing block 3 has a male mold portion 14, the supporting block 4 has a female mold portion 15, and the pressing block 3 and the lifting portion 2, and the supporting block 4 and the frame 1 are all detachably connected, it is convenient to replace different processing molds.

[0036] First, remove the original pressing block 3 from the lifting part 2, and remove the bearing block 4 from the frame 1. According to the shape requirements of the new workpiece, select a pressing block 3 with a suitable male mold part 14 and a bearing block 4 with a corresponding female mold part 15 for installation. After the installation is completed, connect the air delivery pipe 10 to the end of the blowing hole 6 on the new pressing block 3.

[0037] First, this detachable connection design enables the press to adapt to the processing requirements of workpieces of different shapes, improving the versatility and flexibility of the press. There is no need to equip a separate press for each workpiece of different shapes, which greatly reduces the equipment cost. Secondly, the pressing block 3 and the lifting part 2 are fixed with bolts, and the process of replacing the mold is simple and quick. The air supply pipe 10 can be connected to the end of the blowing hole 6 of the new pressing block 3, which saves time and labor costs and improves production efficiency.

[0038] Furthermore, it also includes a rotating shaft 16 and a film roll 17. The rotating shaft 16 is rotatably arranged on the frame 1. There are two rotating shafts 16, which are respectively located on both sides of the supporting block 4. The film roll 17 is sleeved on one of the rotating shafts 16. The film roll 17 is used to release a protective film 18 covering the product. After the rotating shaft 16 rotates, it is used to gradually wind the protective film 18 onto the other rotating shaft 16.

[0039] Furthermore, two sides of the protective film 18 have base bands 19 , and the protective film 18 is made of transparent material.

[0040] In this embodiment, in order to protect the surface of the metal sheet workpiece that is easy to bend from being scratched during the processing, film rolls 17 are arranged on the rotating shafts 16 on both sides of the carrier block 4. The film roll 17 is mounted on one of the rotating shafts 16, and the film roll 17 can release a protective film 18 of a transparent material to cover the product. Before the processing starts, the protective film 18 is evenly covered on the surface of the workpiece.

[0041] When stamping, the protective film 18 is very thin and will not affect the processing accuracy of the workpiece. At the same time, the transparent protective film 18 is also convenient for the operator to observe the processing process. After using the same section of protective film 18 for many times, if the protective film 18 is damaged, the two rotating shafts 16 can be rotated. One of the rotating shafts 16 gradually winds up the old protective film 18, while the other rotating shaft 16 releases a new protective film 18, so that the product is always covered with a good protective film 18.

[0042] In order to ensure that the excessively damaged protective film 18 can also move smoothly with the rotation of the rotating shaft 16, a base belt 19 is provided on both sides of the protective film 18. The base belt 19 is made of a durable material. During the use of the protective film 18, even if the protective film 18 is excessively damaged, the base belt 19 can still drive the protective film 18 to move. In addition, since the position of the base belt 19 will not be contacted by the male mold part 14 and the female mold part 15, the base belt 19 will not be damaged during the processing.

[0043] Furthermore, the frame 1 has a bearing platform 20 , and the bearing platform 20 has a plurality of T-slots 21 . The bearing blocks 4 are detachably disposed in the T-slots 21 .

[0044] In this embodiment, when the bearing block 4 needs to be installed or replaced, the special structure of the T-slot 21 can be used for operation. First, align the connecting parts on the bearing block 4 with the T-slot 21, and then fix the bearing block 4 in the T-slot 21 through specific connecting parts, such as T-bolts. When replacing the bearing block 4, it is only necessary to loosen the connecting parts, remove the old bearing block 4 from the T-slot 21, and then install the new bearing block 4 according to the same steps. The design of the T-slot 21 provides great convenience for the installation and replacement of the bearing block 4. The operator can perform installation and replacement operations quickly and accurately, saving time and labor costs. This detachable connection method enables the press to flexibly replace bearing blocks 4 of different specifications according to different processing requirements, thereby improving the versatility and adaptability of the press.

[0045] Furthermore, it also includes a film supporting frame 22, which is movably arranged relative to the supporting block 4, and is used to support the protective film 18 upward after the film supporting frame 22 moves.

[0046] Furthermore, it also includes a bracket 23 and a connecting rod 24. The bracket 23 is detachably arranged in the T-slot 21. Two ends of the connecting rod 24 are respectively hinged to the bracket 23 and the film supporting frame 22 for driving the film supporting frame 22 to move.

[0047] Furthermore, it also includes a lever 25 and a rotating sleeve 26 , wherein the rotating sleeve 26 is rotatably disposed on the bracket 23 , the lever 25 is slidably disposed on the rotating sleeve 26 , and an end of the lever 25 is hinged to the film supporting frame 22 .

[0048] In this embodiment, after processing a workpiece, in order to facilitate the placement of new raw materials, the operator can operate the film support frame 22 through the following steps. First, one end of the lever 25 is pressed down. Since the lever 25 is slidably arranged on the rotating sleeve 26, and the rotating sleeve 26 is rotatably arranged on the bracket 23, when one end of the lever 25 is pressed down, the other end of the lever 25 will move upward, and the end of the lever 25 is hinged to the film support frame 22. As the other end of the lever 25 moves upward, the film support frame 22 is propped up.

[0049] During this process, the middle part of the lever 25 will slide in the rotating sleeve 26, and the multiple connecting rods 24 will also swing. The four connecting rods 24 and the film support frame 22 form a parallel four-link 24 structure, which enables the film support frame 22 to be propped up in a horizontal state. When the film support frame 22 is propped up, the protective film 18 is also propped up, thereby making room for placing new raw materials on the support block 4. The operator can more conveniently place new easy-to-bend metal sheet workpiece raw materials on the support block 4, and then put down the film support frame 22 so that the protective film 18 covers the new raw materials, ready for the next processing operation.

[0050] First, by providing the film support frame 22 and related operating structures, the convenience of placing new raw materials is greatly improved. Operators do not need to place raw materials with difficulty under the obstruction of the protective film 18, which improves work efficiency. Secondly, the parallel four-link 24 structure ensures the horizontal state of the film support frame 22 during the support process, avoids unnecessary pulling or damage to the protective film 18 due to tilting of the protective film 18, and extends the service life of the protective film 18. At the same time, the bracket 23 is detachably arranged in the T-slot 21, which is convenient for installation and adjustment of position according to actual needs, further improving the versatility and flexibility of the press.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
