Description

Technical Field

[0001] This utility model relates to the technical field of suspension forgings, and in particular to a cold heading forming equipment for suspension forgings. Background Technology

[0002] Suspension forgings refer to metal components used in various suspension systems, produced through forging processes. Their core function is to connect, bear, or transmit loads. Cold heading is used in the manufacture of suspensions. Cold heading is a forging process that applies external force to metal materials at room temperature and causes plastic deformation of the material through a die to obtain a workpiece of the required shape and size. It belongs to a type of cold plastic forming technology. Cold heading is a "minimum or no cutting process" in which the metal billet is directly extruded and deformed through a die. The material only flows inside the die cavity and produces almost no waste. Therefore, the material utilization rate is very high, saving raw materials. Hence, there is a particular need for cold heading forming equipment for suspension forgings.

[0003] However, in most existing cold heading forming equipment for suspension forgings, the molds are fixed and cannot be replaced, making it impossible to adapt to different processing requirements and resulting in poor processing effects.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN 115301872 A, which discloses a cold heading forming device for rivet nuts. The patent states that "in actual use, cold heading machines are prone to problems such as burrs and dirt on the surface of the cut material, affecting the cold heading accuracy and even causing the nut to get stuck in the mold and unable to be demolded. Uneven addition of cold heading oil can lead to deformation and cracks during the cold heading process, and the cold-headed nut is mixed with oil and dirt, affecting the nut quality." This invention addresses these issues by incorporating a frame, a sandblasting and chip removal mechanism, a hydraulic robotic arm, an upper cold heading mold, a lower cold heading mold, a transfer robotic arm, a cold heading oil nozzle, a small oil pump, an oil storage tank, an overflow hole, a receiving trough, a vibrating chip removal base plate, and an electric... The combination of indexing shaft, electromagnet, electric telescopic discharge plate, and discharge chute, after testing and optimization, enables the equipment to polish and deburr rivet nuts, uniformly add cold heading oil to the cold heading die, and automatically discharge the cold-headed rivet nuts, ensuring the cold heading quality and precision of the rivet nuts. It can also vibrate the cold-headed rivet nuts to remove oil and chips, facilitating the collection and storage of rivet nuts. At the same time, it can also separate oil and chips to facilitate the recycling of cold heading oil and save production costs. However, the mold of the cold heading machine cannot be quickly changed, cannot adapt to different processing needs, and the processing effect is poor.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

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.

[0018] Please see Figure 1-5This utility model provides a technical solution: a cold heading forming equipment for suspension forgings, including a processing table 1, a mounting frame 8 fixedly mounted on one side surface of the processing table 1, a hydraulic cylinder 9 fixedly mounted on the upper side surface of the mounting frame 8, a lifting plate 10 fixedly connected to the output end of the hydraulic cylinder 9, an upper mold 11 fixedly mounted on the lower side surface of the lifting plate 10, a connecting frame 12 fixedly mounted on one side surface of the processing table 1, a connecting groove 13 formed on one side surface of the connecting frame 12, and a sliding groove 14 formed on the inner wall of one side of the connecting frame 12, the interior of the sliding groove 14 being provided with a removable... A movable slider 15 has a screw 16 welded to one side surface. A nut 17 is threaded onto one end of the screw 16. A movable plate 18 is fixedly connected to one side surface of the slider 15. A storage groove 19 is formed inside the movable plate 18, and a spring 20 is fixedly installed inside the storage groove 19. A locking block 21 is fixedly connected to the other end of the spring 20. A pull rod 22 is fixedly installed on the side surface of the locking block 21 connected to the spring 20. A mounting block 23 is embedded in the opening of the movable plate 18. A slot 24 is formed on one side surface of the mounting block 23. A lower mold 25 is fixedly mounted on the surface. Through the arrangement of the machining table 1, mounting bracket 8, hydraulic cylinder 9, lifting plate 10, upper mold 11, connecting bracket 12, connecting groove 13, sliding groove 14, slider 15, screw 16, nut 17, moving plate 18, storage groove 19, spring 20, locking block 21, pull rod 22, mounting block 23, locking slot 24, and lower mold 25, when the lower mold 25 needs to be replaced, loosen the nut 17 and pull the moving plate 18. The moving plate 18 will move the lower mold 25 to a position further out on the machining table 1. At this time, pulling the pull rod 22 will lock the lower mold 25. When block 21 is pulled into the storage slot 19, the locking block 21 leaves the slot 24, and the mounting block 23 can then take the lower mold 25 away from the moving plate 18. Then, the mounting block 23 at the lower end of the lower mold 25 that needs to be replaced is inserted into the opening of the moving plate 18. After the mounting block 23 is fully inserted into the moving plate 18, the locking block 21 will be locked in the slot 24 under the elastic force of the spring 20. This completes the replacement of the lower mold 25. The operation is simple and convenient, and the replacement of the lower mold 25 improves the processing effect, can adapt to more processing work with different requirements, and also facilitates the maintenance of the lower mold 25.

[0019] Furthermore, the slider 15 forms a sliding structure with the connecting frame 12 through the slide groove 14. With the setting of the slide groove 14 and the slider 15, the slider 15 can assist and limit the movement of the moving plate 18 when it slides in the slide groove 14.

[0020] Furthermore, the screw 16 forms a sliding structure with the connecting frame 12 through the connecting groove 13. One end of the screw 16 passes through the connecting groove 13 and is threadedly connected to the nut 17. Through the setting of the screw 16 and the nut 17, the screw 16 and the nut 17 can fix the position of the slider 15, thereby fixing the position of the moving plate 18.

[0021] Furthermore, the size of the locking block 21 matches that of the locking slot 24. The locking block 21 and the mounting block 23 form a locking structure through the locking slot 24. With the setting of the locking block 21 and the locking slot 24, when the locking block 21 is fixed in the locking slot 24, the mounting block 23 will be fixed in the opening of the moving plate 18, thus completing the installation and fixing of the lower mold 25.

[0022] Furthermore, the locking block 21 forms a telescopic structure with the moving plate 18 via the spring 20. With the spring 20, the locking block 21 can be fixed in the slot 24 under the elastic force of the spring 20.

[0023] Furthermore, a motor 2 is fixedly installed on one side surface of the processing table 1. A connecting shaft 3 is fixedly connected to the output end of the motor 2. A chain 4 is connected to the outer wall of the connecting shaft 3 via a sprocket. A mounting plate 5 is installed on one side surface of the chain 4. A cylinder 6 is fixedly installed on one side surface of the mounting plate 5. A fixing plate 7 is fixedly connected to the output end of the cylinder 6. Through the arrangement of the motor 2, connecting shaft 3, chain 4, mounting plate 5, cylinder 6, and fixing plate 7, when processing is performed, the motor 2 drives the connecting shaft 3 to rotate. Under the action of the gears, the chain 4 will drive the mounting plate 5 to move. The cylinder 6 can allow the fixing plate 7 to clamp the processing material. When the processing material moves to the middle between the upper mold 11 and the lower mold 25, the fixing plate 7 releases the material for processing. After the material is ejected from the lower mold 25, the fixing plate 7 clamps the material again and transports the material, realizing automated processing.

[0024] Furthermore, the connecting shaft 3 is provided in two sets, one of which is fixed to the output end of the motor 2. The connecting shaft 3 and the processing table 1 form a rotating structure. By setting the connecting shaft 3, when the connecting shaft 3 rotates, the chain 4 can move with the mounting plate 5, thereby transporting the processing materials.

[0025] Working principle: When the lower mold 25 needs to be replaced, loosen the nut 17 and pull the moving plate 18. The moving plate 18 will move the lower mold 25 to the outer position of the processing table 1. At this time, pull the pull rod 22, which will pull the locking block 21 into the storage groove 19. At this time, the locking block 21 will leave the slot 24, and the mounting block 23 can then move the lower mold 25 away from the moving plate 18. Then, the mounting block 23 at the lower end of the lower mold 25 to be replaced is inserted into the opening of the moving plate 18. After the mounting block 23 is fully inserted into the moving plate 18, the locking block 21 will be locked in the slot 24 under the elastic force of the spring 20. This completes the replacement of the lower mold 25.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
