[0026] Embodiment

[0027] This embodiment provides an automatic feeding and punching device for an automobile energy absorption box, and the energy absorption box is a square tube structure with a partition in the middle. As Figure 1 and Figure 2 shown, the device includes a stamping die base 10, a positioning component 11, a positioning seat 12, a first driving cylinder 13, and a transplanting mechanism 20.

[0028] There are multiple stamping stations arranged on the stamping die base 10. Along the flow direction of the energy-absorbing box, they are respectively the first side stamping station, the second side stamping station, the first stamping station on the third side, the second stamping station on the third side, and the fourth side stamping station. Each stamping station is provided with two symmetrically distributed positioning seats 12, and a positioning component 11 is slidably arranged on the stamping station. The positioning component 11 includes a positioning plate 111 for lateral positioning and locking of the energy-absorbing box. Positioning pins 112 are arranged on the positioning plate 111 where the first stamping station on the third side, the second stamping station on the third side, and the fourth side stamping station are located, and are used to correspond and insert pins with the hole positions of the first two steps of punching on the energy-absorbing box to achieve precise positioning. A small cylinder 113 is arranged in the groove at the bottom of the stamping station. The telescopic end of the small cylinder 113 is connected to the positioning plate 111 and is used to drive the positioning plate 111 to slide, realizing the telescopic movement of the positioning plate 111, so as to press or loosen the side wall of the energy-absorbing box.

[0029] The positioning plate 111 is located on one side of the positioning seat 12 to ensure a stable cooperation with the positioning seat 12 during the positioning process.

[0030] The stamping station is provided with a positioning seat 12. The positioning seat 12 includes a first positioning block 121 and a second positioning block 122 fixed on the stamping station. A clearance is arranged between the first positioning block 121 and the second positioning block 122 for the energy-absorbing box to be sleeved. Through the design of the positioning seat 12, the stability of the energy-absorbing box during the stamping process can be ensured.

[0031] It should be noted that the angles of the first positioning block 121 and the second positioning block 122 on the first side stamping station, the second side stamping station, the first stamping station on the third side, the second stamping station on the third side, and the fourth side stamping station correspond to the punching angles of the energy-absorbing box, and are used for the energy-absorbing box to realize the clamping for punching operations on each side.

[0032] The setting of the transplanting mechanism 20 enables this device to realize automatic feeding and rotation operations. The transplanting mechanism 20 includes a first driving mechanism moving along the X-axis and a second driving mechanism moving along the Y-axis. The second driving mechanism is arranged at the action output part of the first driving mechanism, so as to realize the movement of the transplanting mechanism 20 in the two-dimensional plane. In this embodiment, both the first driving mechanism and the second driving mechanism adopt the driving setting of a motor driving a lead screw nut and are assisted by a guide rail slider mechanism for sliding. An installation frame is arranged at the action output part of the second driving mechanism, and a plurality of vertical plates are fixedly arranged on the installation frame. Rotary clamping cylinders 21 for clamping the energy-absorbing box are arranged on the vertical plates. Through the rotary clamping cylinders 21, the clamping and rotation of the energy-absorbing box can be realized, so as to facilitate the commutation punching operation on the four sides of the energy-absorbing box.

[0033] Furthermore, a second driving cylinder 22 is also provided on the vertical plate, and a pushing block 23 is connected to the telescopic rod of the second driving cylinder 22. The pushing block 23 is arranged in an H shape, which facilitates the bolt connection between the pushing block 23 and the connecting block of the telescopic rod of the second driving cylinder 22, and the side surface of the pushing block 23 in contact with the energy absorption box is parallel to the end face of the energy absorption box and is arranged as an inclined surface. When the transplanting mechanism 20 sends the energy absorption box to the stamping station, the telescopic rod of the second driving cylinder 22 extends, pushing the pushing block 23 to abut the end of the energy absorption box against the positioning edge of the positioning seat 12, ensuring the accuracy and stability of the energy absorption box during the stamping process.

[0034] Finally, a blanking conveyor line 14 is also provided at the blanking end of the stamping die base 10 for conveying the punched energy absorption box to the next process.

[0035] The working principle of the present utility model is as follows:

[0036] Two energy absorption boxes to be punched are sent to the first side stamping station for punching through the transplanting mechanism 20. At the same time, the two energy absorption boxes that have been punched at the first side stamping station are rotated 90° in the reverse direction and transplanted to the second side stamping station. The energy absorption boxes that have been punched at the second side stamping station are rotated 90° in the reverse direction and transplanted to the third side primary stamping station. The two energy absorption boxes that have been punched at the third side primary stamping station are transplanted to the third side secondary stamping station. The two energy absorption boxes that have been punched at the third side secondary stamping station are rotated 90° in the reverse direction and transplanted to the fourth side stamping station. The two energy absorption boxes that have been punched at the fourth side stamping station are transplanted to the blanking conveyor line 14 and sent out along the blanking conveyor line 14. After the transplanting of the energy absorption box is completed, the telescopic rod of the second driving cylinder 22 extends, pushing the pushing block 23 to abut the end of the energy absorption box against the positioning seat 12 to achieve the preliminary positioning of the energy absorption box. Then, the small cylinder drives the positioning plate 111 to slide, and the positioning pin 112 corresponds to the hole position on the energy absorption box to achieve the precise positioning of the energy absorption box. Then, the punching operation is carried out. After the punching is completed, the telescopic end of the first driving cylinder 13 extends, pushing the push rod to push the energy absorption box out of the positioning seat 12 and transplanting it to the next process through the rotary clamping cylinder 21.

[0037] Through the above steps, the automatic feeding and punching device for the automobile energy absorption box of the present utility model realizes the automatic feeding, precise positioning and punching operation of the energy absorption box, improves the punching efficiency, and at the same time ensures the positional accuracy of the holes.

[0038] Inspired by the above ideal embodiments based on the present application, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
