[0002] Cold extrusion, as an advanced plastic forming technology, is widely used in the machinery manufacturing industry. Currently, this process is mostly implemented on hydraulic presses. Due to the structural limitations of the hydraulic press's ejector cylinder, the feeding and positioning of the billet during cold extrusion production generally rely on manual operation. This traditional manual feeding mode is slow and cannot match the rapid descent and return of the hydraulic press's main cylinder, resulting in increased equipment idle time, lengthening the overall production cycle, and failing to fully utilize the hydraulic press's inherent high-efficiency production capacity. Furthermore, operators must repeatedly insert their hands or body parts into the mold-closing area of ​​the equipment for feeding, coming into extremely close proximity to moving parts such as the hydraulic press's slide. If the equipment malfunctions or personnel make operational errors, it can easily lead to serious personal injury accidents such as crushing or crushing injuries.

[0017] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] Reference Figures 1 to 5 This utility model discloses an automatic shaping and feeding device for a hydraulic press 5, which is installed on one side of the hydraulic press 5 for automatically feeding materials into the hydraulic press 5. The automatic shaping and feeding device for the hydraulic press 5 includes a machine base 1, a material preparation module 2, and a material picking module 3. The machine base 1 serves as the base of the device and is used to support and install various components. A positioning component 4 is installed on the machine base 1 to shape and position parts 6. The material preparation module 2 stores parts 6 and transports parts 6 to the positioning component 4. The material picking module 3 is installed on the machine base 1 and located on one side of the positioning component 4 to transport parts 6 from the positioning component 4 into the hydraulic press 5. By shaping and positioning parts 6 through the positioning component 4 and cooperating with the material picking module 3, automatic feeding of parts 6 is achieved, effectively improving production efficiency and production safety.

[0020] Reference Figure 1 and Figure 2The material preparation module 2 is used to store and transfer parts 6 to the positioning component 4. Specifically, the material preparation module 2 includes a feeding bin 21, a vibratory feeder 22, and a three-axis parallel robot 23. The feeding bin 21 is set on the machine base 1 and is used to store and supply the parts 6 to be stamped to the vibratory feeder 22. The vibratory feeder 22 is set at the outlet of the feeding bin 21. The feeding bin 21 puts the parts 6 onto the vibratory feeder 22. The vibratory feeder 22 vibrates regularly and performs preliminary shaping and positioning with the parts 6 so that the three-axis parallel robot 23 can accurately pick up the parts 6 one by one. The three-axis parallel robot 23 is used to transport the parts 6 on the vibratory feeder 22 to the positioning component 4. The three-axis parallel robot 23 consists of three kinematic chains. Each kinematic chain is set as a linkage mechanism, which connects the motion platform and the fixed platform. Each axis of the three-axis parallel robot 23 can be driven independently to achieve three-dimensional space driving. The specific structure and working principle of the three-axis parallel robot 23 can refer to the existing technology and will not be elaborated here. In this embodiment, the motion platform of the three-axis parallel robot 23 is equipped with an air nozzle 231. The three-axis parallel robot 23 uses the air nozzle 231 to pick up the part 6, thereby transporting the part 6. The three-axis parallel robot 23 is also equipped with a vision imaging system (not shown in the figure). The vision imaging system identifies the information of the part 6 on the vibratory feeder 22 by taking pictures and sends the position information of the part 6 to the three-axis parallel robot 23. The three-axis parallel robot 23 picks up the part 6 according to the position information and transmits the picked-up gear to the positioning component 4 for further positioning and shaping.

[0021] Reference Figure 1 and Figure 3 The positioning component 4 is used to position and shape the part 6. Specifically, the positioning component 4 includes a base 41, a positioning fixing plate 42, and a positioning block 43. The base 41 is mounted on the machine base 1, and a mounting frame 11 is fixedly mounted on the machine base 1. The positioning fixing plate 42 is fixedly connected to the base 41 and has a positioning groove 421. The positioning block 43 is detachably mounted in the positioning groove 421. A top cover plate 422 is detachably connected to the positioning fixing plate 42, and the top cover plate 422 presses and fixes the positioning block 43. The top cover plate 422 and the positioning fixing plate 42 can be locked and fixed together by common fasteners such as bolts. In this embodiment, the positioning block 43 is provided with a positioning protrusion 431 and a positioning inclined surface 432. For irregularly shaped parts 6, the positioning protrusion 431 and the positioning inclined surface 432 can be adapted to their shape to position and shape the part 6. In other embodiments, the structure of the positioning block 43 can be adapted to the shape of the part 6, and is not limited to a single configuration. By replacing different positioning blocks 43, positioning and shaping of parts 6 with different shapes can be achieved, thereby expanding the applicability of the device.

[0022] Reference Figure 3 Furthermore, the positioning assembly 4 also includes a first finger cylinder 44 for clamping and positioning the part 6 on the positioning block 43. The first finger cylinder 44 is fixedly mounted on the positioning fixing plate 42 and located on one side of the positioning groove 421. Both output shafts of the first finger cylinder 44 are fixedly connected to positioning clamping blocks 45. The first finger cylinder 44 can drive the two positioning clamping blocks 45 to move closer or further apart. Each of the two positioning clamping blocks 45 has a limiting protrusion 451 fixedly provided on its opposite side. Under the drive of the first finger cylinder 44, the positioning clamping blocks 45 clamp the part 6, and the part 6 is further positioned and shaped by the cooperation of the limiting protrusion 451 and the positioning protrusion 431 on the positioning block 43.

[0023] In this embodiment, the positioning component 4 is equipped with two sets of first finger cylinders 44, which can simultaneously position and shape two parts 6 to improve positioning and shaping efficiency.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The material handling module 3 includes a lifting assembly, a traversing assembly, and a gripper assembly 33. The gripper assembly 33 is used to grip the part 6, the lifting assembly is used to drive the gripper assembly 33 to perform lifting and lowering movements, and the traversing assembly is used to drive the gripper assembly 33 to move horizontally towards the hydraulic press 5. Through the cooperation of the lifting assembly and the traversing assembly, the gripper assembly 33 can pick up the part 6 and place the part 6 into the hydraulic press 5.

[0025] Reference Figure 4 The gripper assembly 33 includes a material-grabbing fixing block 332 and a second finger cylinder 331. The second finger cylinder 331 is fixedly connected to the material-grabbing fixing block 332. Both output shafts of the second finger cylinder 331 are fixedly equipped with material-grabbing clamping blocks 333. The second finger cylinder 331 can drive the two material-grabbing clamping blocks 333 to move closer or further away from each other to clamp or release the part 6.

[0026] Furthermore, a slide rail 334 is fixedly installed on the material-grabbing fixing block 332, with its extension direction parallel to the movement direction of the material-grabbing clamping block 333. A slider 335, corresponding to each material-grabbing clamping block 333, is slidably connected to the slide rail 334. The material-grabbing clamping block 333 and the slider 335 are fixedly connected. The second finger cylinder 331 drives the material-grabbing clamping block 333 to move, causing the slider 335 to slide on the slide rail 334. By setting the matching slide rail 334 and slider 335, the movement path of the material-grabbing clamping block 333 is restricted and guided, ensuring the stability of the movement of the material-grabbing clamping block 333 and reducing the risk of the zero point 6 falling due to vibration.

[0027] Reference Figure 4The lifting assembly includes a lifting linear module 31, and the lateral movement assembly includes a lateral movement linear module 32. An auxiliary mounting plate 12 located on one side of the positioning assembly 4 is fixedly mounted on the mounting bracket 11, and the lifting linear module 31 is fixedly connected to the auxiliary mounting plate 12. A connecting plate 34 is provided on the lifting linear module 31, and the lifting linear module 31 can drive the connecting plate 34 to rise and fall. The lateral movement linear module 32 is fixedly connected to the connecting plate 34, and the gripper assembly 33 is connected to the lateral movement linear module 32. The lifting linear module 31 drives the connecting plate 34 to rise and fall, thereby driving the entire lateral movement linear module 32 to rise and fall, thus realizing the rise and fall of the gripper assembly 33; while the lateral movement of the gripper assembly 33 is driven by the lateral movement linear module 32.

[0028] Furthermore, the transverse assembly also includes a mounting plate 35, which is connected to the transverse linear module 32. The transverse linear module 32 can drive the mounting plate 35 to move horizontally closer to or further away from the hydraulic press 5. An extension arm 36 extending axially along the transverse linear module 32 is fixedly mounted on the mounting plate 35, and a material-picking fixing block 332 is connected to the extension arm 36. When the transverse linear module 32 drives the mounting plate 35 to move towards the end of the hydraulic press 5, the extension arm 36 extends into the hydraulic press 5 so that the gripper assembly 33 can place the part 6 on the stamping platform of the hydraulic press 5. When the transverse assembly drives the mounting plate 35 back to its original position, the extension arm 36 retracts from the hydraulic press 5 so that the hydraulic press 5 can perform stamping operations. By setting the extension arm 36, the gripper assembly 33 can move into the hydraulic press 5 to pick up and place the part 6; and can completely retract from the hydraulic press 5, effectively reducing the possibility of interference between the material-picking module 3 and the hydraulic press 5, and ensuring production safety.

[0029] In this embodiment, a material picking plate 361 is fixedly connected to the extension arm 36, and four sets of gripper assemblies 33 are arranged in an array on the material picking plate 361.

[0030] During operation, the transverse linear module 32 drives the gripper assembly 33 to move above the positioning assembly 4. Then, the lifting linear module 31 drives the transverse linear module 32 to descend as a whole until the gripper assembly 33 can grip the part 6 on the positioning assembly 4. After the gripper assembly 33 clamps the part 6, the lifting linear module 31 drives the transverse linear module 32 to rise. Then, the transverse linear module 32 drives the gripper assembly 33 to move into the hydraulic press 5, and the lifting linear module 31 drives the transverse linear module 32 to descend until the gripper assembly 33 places the part 6 on the stamping platform of the hydraulic press 5. The transverse linear module 32 and the lifting linear module 31 then drive the gripper assembly 33 to return to its original position, and the hydraulic press 5 can then perform stamping operations on the part 6.

[0031] It should be noted that the linear module consists of components such as linear guide rails, ball screws, and drive motors. Those skilled in the art can realize the lifting and lateral movement drive of the gripper assembly 33 based on existing technology and common knowledge in the field. Therefore, its specific connection structure and driving principle will not be described in detail here.

[0032] The implementation process of the automatic shaping and feeding device for the hydraulic press 5 of this utility model is as follows: First, part 6 is placed into the feeding bin 21, which then feeds part 6 in batches onto the vibratory feeder 22. The vibratory feeder 22 vibrates regularly to perform initial shaping and positioning of part 6. Next, the three-axis parallel robot 23 transfers part 6 from the vibratory feeder 22 to the positioning assembly 4, where the first finger cylinder 44 further shapes and positions part 6. Then, the picking module 3 drives the gripper assembly 33 to pick up part 6 from the positioning assembly 4 and transfer it to the stamping platform of the hydraulic press 5. Finally, the picking module 3 returns to its original position and picks up part 6 again, while the hydraulic press 5 stamps part 6. This process is repeated.

[0033] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
