Description

Technical Field

[0001] This invention relates to the field of stamping technology, and more particularly to a stamping equipment for automotive parts. Background Technology

[0002] Automotive parts refer to various components that make up the overall structure of a vehicle, including but not limited to body panels, structural support components, chassis components, and various stamped parts. A large number of automotive parts are formed through stamping processes. Stamping equipment uses dies to apply pressure to sheet metal, causing it to undergo plastic deformation or separation, thereby obtaining parts of the required shape and size. In existing technologies, during the stamping manufacturing of common automotive parts, the operator places the part to be stamped on the stamping die, activates the drive mechanism to move the stamping head downwards, completes the stamping process, moves the stamping head upwards, and then the operator manually removes the stamped part from the stamping die, before starting the next work cycle.

[0003] However, existing stamping equipment still has shortcomings in practical applications. Most existing equipment adopts a single-station structure, that is, stamping and loading / unloading operations are carried out alternately at the same station. This working mode results in the equipment being idle during loading / unloading, and the equipment utilization rate is low. After stamping, the parts often have a certain degree of adhesion or jamming with the stamping die, which requires the operator to manually remove them. Since the stamped parts may be tightly fitted to the die cavity, the operator needs to apply a lot of force or use auxiliary tools such as pry bars when removing the parts, which is laborious and time-consuming. At the same time, there is a great safety hazard in reaching the die area with one's hands. If the equipment starts unexpectedly or the sensor fails, it is very easy to cause safety accidents such as crushing and pinching injuries.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a stamping equipment for automotive parts, so as to solve the problem that the parts often have a certain degree of adhesion or jamming with the stamping die, requiring the operator to manually remove them.

[0006] To achieve the above objectives, the present invention provides a stamping equipment for automotive parts, including a stamping table and two support seats disposed above the stamping table. The stamping table is provided with a driving mechanism for driving a stamping head to perform stamping. The support seats are provided with a receiving groove for accommodating a stamping die. A fixing structure for fixing the stamping die is installed on the support seats. A support column is fixedly connected to the bottom of the support seats, and an ejection mechanism is installed on the support column. A rotating frame is provided above the stamping table. A self-rotating mechanism for driving the rotating frame to rotate is installed on the stamping table. The support column and the rotating frame are rotatably connected. An inclined structure for driving the support column to rotate is installed on the stamping table. A guide hopper for receiving materials is fixedly connected to the stamping table.

[0007] Optionally, the inclined structure includes a C-shaped strip fixedly installed on the top of the stamping table, a translation seat adapted to the notch of the C-shaped strip on the stamping table, a slider below the support column, and grooves that cooperate with the slider on both the C-shaped strip and the translation seat. A first hydraulic telescopic rod is fixedly connected to the stamping table, and the telescopic end of the first hydraulic telescopic rod is fixedly connected to the translation seat. A sliding component adapted to the support column is installed on the slider.

[0008] Optionally, the sliding member includes a movable plate rotatably mounted on the slider, and a groove adapted to the movable plate is provided on the support column, and the movable plate is slidably mounted in the groove.

[0009] Optionally, the ejection mechanism includes a second hydraulic telescopic rod fixedly installed on the support column. The telescopic end of the second hydraulic telescopic rod is fixedly connected to an ejection block for ejecting the stamped part from the stamping die, and the bottom of the inner wall of the receiving groove is provided with an avoidance hole adapted to the ejection block.

[0010] Optionally, the drive mechanism includes a fixed frame fixedly installed on the stamping table, and a mounting seat for fixing the stamping head is provided above the stamping table. A third hydraulic telescopic rod is fixedly connected to the fixed frame, and the telescopic end of the third hydraulic telescopic rod is fixedly connected to the mounting seat.

[0011] Optionally, the fixing structure includes several clamps disposed in the receiving groove, the bottom of the clamps contacting the bottom of the inner wall of the receiving groove, a screw is fixedly connected to the clamp, the screw passes through the support seat, a threaded sleeve is fitted on the external thread of the screw, and the threaded sleeve and the support seat are rotatably connected, and a locking component that cooperates with the threaded sleeve is installed on the support seat.

[0012] Optionally, the locking component includes a fixing ring fixedly sleeved on the outside of the threaded sleeve, a support part provided below the fixing ring, the support part and the support seat fixedly connected, a positioning post passing through the support part, a fixing plate fixedly connected to the bottom end of the positioning post, a plurality of positioning grooves opened on the fixing ring, the top end of the positioning post located in the corresponding positioning groove, a tension spring sleeved on the outside of the positioning post, and the two ends of the tension spring being fixedly connected to the fixing plate and the support part respectively.

[0013] Optionally, the rotation mechanism includes a rotating shaft fixedly mounted on a rotating frame, the rotating shaft being rotatably connected to a stamping table, a servo motor being fixedly connected to the stamping table, and the output end of the servo motor being fixedly connected to the rotating shaft.

[0014] Optionally, the bottom of the rotating frame is fixedly connected to several fixed columns, and the bottom end of the fixed columns is fixedly connected to a roller, with the bottom end of the roller contacting the top of the stamping table.

[0015] The beneficial effects of this invention are as follows: After stamping, the rotating frame is driven to rotate by a self-rotating mechanism, so that the stamped part and the support base rotate to the loading and unloading station. The support column is driven to tilt relative to the rotating frame by an inclined structure, and the ejection mechanism ejects the stamped part from the stamping die through the ejection hole on the stamping die. The stamped part falls from the stamping die onto the guide hopper, and can then slide to a preset position through the guide hopper, completing automatic unloading. The inclined structure drives the support column to tilt relative to the rotating frame, and in conjunction with the ejection mechanism, ejects the stamped part from the ejection hole on the stamping die, so that the stamped part automatically falls onto the guide hopper under gravity and slides along the guide hopper. Upon reaching the preset position, this design enables automatic demolding and collection after stamping, eliminating the need for operators to manually remove workpieces from the stamping die. This avoids cycle time delays caused by untimely part removal. While the loading and unloading stations are placing the parts to be stamped and removing the stamped parts, the stamping station can simultaneously perform stamping operations without waiting for manual loading and unloading to be completed before starting stamping. This effectively eliminates the equipment downtime caused by loading and unloading in traditional single-station stamping equipment, significantly improving equipment utilization and output per unit time, reducing the safety risks of operators' hands reaching into the die area, and reducing the labor intensity of manual material handling.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0020] Example 1, by Figure 1 The present invention includes a stamping table 1 and two support seats 2 disposed above the stamping table 1. The stamping table 1 is provided with a driving mechanism for driving the stamping head to perform stamping. The support seats 2 are provided with a receiving groove 3 for accommodating the stamping die. The support seats 2 are equipped with a fixing structure for fixing the stamping die. The bottom of the support seats 2 is fixedly connected to a support column 4, and an ejection mechanism is installed on the support column 4. A rotating frame 5 is provided above the stamping table 1. A rotation mechanism for driving the rotating frame 5 to rotate is installed on the stamping table 1. The support column 4 and the rotating frame 5 are rotatably connected. An inclined structure for driving the support column 4 to rotate is also installed on the stamping table 1. A material guide hopper 6 for receiving materials is fixedly connected to the stamping table 1. The operator fixes the stamping head to the drive mechanism, and then the operator fixes the stamping die in the receiving groove 3 through the fixing structure. One support seat 2 is located at the stamping station, and the other support seat 2 is located at the loading and unloading station. The operator places the part to be stamped in the stamping die located at the loading and unloading station. Then, the rotating frame 5 is driven to rotate by the rotation mechanism, so that the support seat 2 containing the part to be stamped rotates to the stamping station. The stamping head is driven to move down by the drive mechanism. Through the cooperation of the stamping head and the stamping die, stamping can be performed. After stamping, the rotating frame 5 is driven to rotate by the rotation mechanism, so that the stamped part and the support seat 2 rotate to the loading and unloading station. The tilting structure drives the support column 4 to tilt relative to the rotating frame 5, and the ejection mechanism pushes the stamping head to the loading and unloading station. The ejector hole on the die ejects the stamped part from the die. The stamped part falls onto the guide hopper 6 and slides to a preset position, completing the automatic unloading. The inclined structure drives the support column 4 to tilt relative to the rotating frame 5, and in conjunction with the ejector mechanism, ejects the stamped part from the ejector hole on the die. Under gravity, the stamped part automatically falls onto the guide hopper 6 and slides down to the preset position. This design achieves automatic demolding and automatic collection after stamping, eliminating the need for manual operation. Removing the workpiece from the stamping die avoids cycle delays caused by untimely part removal. While placing the workpiece to be stamped at the loading and unloading station and removing the stamped workpiece, the stamping station can perform stamping operations simultaneously without waiting for manual loading and unloading to be completed before starting stamping. This effectively eliminates the equipment downtime caused by loading and unloading in traditional single-station stamping equipment, greatly improves equipment utilization and output per unit time, reduces the safety risk of operators' hands reaching into the die area, and reduces the labor intensity of manual material handling.

[0021] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 and Figure 4The inclined structure includes a C-shaped strip 8 fixedly installed on the top of the stamping table 1. The stamping table 1 is provided with a translation seat 9 adapted to the notch of the C-shaped strip 8. A slider 7 is provided below the support column 4. Both the C-shaped strip 8 and the translation seat 9 are provided with a sliding groove 10 that cooperates with the slider 7. A first hydraulic telescopic rod 11 is fixedly connected to the stamping table 1. The telescopic end of the first hydraulic telescopic rod 11 is fixedly connected to the translation seat 9. A sliding component adapted to the support column 4 is installed on the slider 7. The sliding component includes a movable plate 12 rotatably installed on the slider 7. A groove 13 adapted to the movable plate 12 is provided on the support column 4. The movable plate 12 is slidably installed in the groove 13. The ejection mechanism includes a second hydraulic telescopic rod 14 fixedly installed on the support column 4. An ejection block 15 for ejecting the stamped part from the stamping die is fixedly connected to the telescopic end of the second hydraulic telescopic rod 14. An avoidance hole 16 adapted to the ejection block 15 is provided at the bottom of the inner wall of the receiving groove 3. When the self-rotating mechanism drives the rotating frame 5 to rotate, the rotating frame 5 drives the support column 4 and the support seat 2 to rotate synchronously. The support column 4 drives the slider 7 to slide in the groove 10 on the C-shaped strip 8 and the sliding seat 9 through the movable plate 12. When the slider 7 slides into the groove 10 on the sliding seat 9, the sliding seat 9 and the slider 7 are translated through the first hydraulic telescopic rod 11. The slider 7 drives the support column 4 to tilt relative to the rotating frame 5 through the movable plate 12, and the movable plate 12 slides relative to the groove 13 and the support column 4. The support column 4 can then drive the support seat 2 and the stamping die to tilt. The ejector block 15 is moved through the second hydraulic telescopic rod 14. The ejector block 15 ejects the stamped part from the stamping die through the clearance hole 16 and the ejection hole on the stamping die.

[0022] Example 3, based on Example 1, is... Figure 1 , Figure 3 and Figure 5The drive mechanism includes a fixed frame 17 fixedly mounted on a stamping table 1. A mounting base 19 for fixing a stamping head is provided above the stamping table 1. A third hydraulic telescopic rod 18 is fixedly connected to the fixed frame 17, and the telescopic end of the third hydraulic telescopic rod 18 is fixedly connected to the mounting base 19. The fixing structure includes several clamping plates 20 disposed within a receiving groove 3. The bottom of the clamping plates 20 contacts the bottom of the inner wall of the receiving groove 3. A lead screw 21 is fixedly connected to the clamping plates 20. The lead screw 21 passes through a support base 2. A threaded sleeve 22 is threaded onto the outer thread of the lead screw 21, and the threaded sleeve 22 is rotatably connected to the support base 2. A locking component that cooperates with the threaded sleeve 22 is installed on the support base 2. The locking component includes a fixing ring 23 fixedly sleeved on the outside of the threaded sleeve 22. A support portion 24 is provided below the fixing ring 23. The part 24 and the support base 2 are fixedly connected. A positioning post 25 passes through the support part 24. A fixed plate 27 is fixedly connected to the bottom end of the positioning post 25. A number of positioning grooves 26 are opened on the fixed ring 23. The top end of the positioning post 25 is located in the corresponding positioning groove 26. A tension spring 28 is sleeved on the outside of the positioning post 25. The two ends of the tension spring 28 are fixedly connected to the fixed plate 27 and the support part 24 respectively. The self-rotation mechanism includes a rotating shaft 29 fixedly installed on the rotating frame 5. The rotating shaft 29 is rotatably connected to the stamping table 1. A servo motor 30 is fixedly connected to the stamping table 1. The output end of the servo motor 30 is fixedly connected to the rotating shaft 29. A number of fixed posts 31 are fixedly connected to the bottom of the rotating frame 5. A roller 32 is fixedly connected to the bottom end of the fixed post 31. The bottom end of the roller 32 is in contact with the top of the stamping table 1. The servo motor 30 drives the rotating shaft 29 and the rotating frame 5 to rotate relative to the stamping table 1. The rotating frame 5 drives the roller 32 to roll on the stamping table 1 via the fixed column 31. Through the cooperation of the fixed column 31 and the roller 32, the rotating frame 5 moves smoothly relative to the stamping table 1. The third hydraulic telescopic rod 18 drives the mounting base 19 to move vertically. The mounting base 19 can then drive the stamping head mounted on the mounting base 19 to move vertically. When the stamping die is installed in the receiving groove 3, the operator drives the fixed plate 27 and the positioning column 25 to move downward. The tension spring 28 is in a stretched state, so that the end of the positioning column 25... The threaded sleeve 22 is disengaged from the corresponding positioning groove 26, releasing the restriction on the position of the fixing ring 23 and the threaded sleeve 22. The operator drives the threaded sleeve 22 and the fixing ring 23 to rotate. The threaded sleeve 22 drives the lead screw 21 and the clamping plate 20 to move. The bottom of the clamping plate 20 slides relative to the bottom of the inner wall of the receiving groove 3, so that several clamping plates 20 clamp the stamping die. Then the operator releases the positioning pin 25, and the tension spring 28 drives the fixing plate 27 and the positioning pin 25 to move upward, so that the top of the positioning pin 25 is inserted into the corresponding positioning groove 26, thereby preventing the threaded sleeve 22 and the fixing ring 23 from rotating and shaking relative to the support seat 2 due to non-human factors.
