The utility model relates to the technical field of laser cutting, and discloses an automatic material receiving pipe cutting machine which comprises a side hanging frame, a portal frame and a supporting frame. A rear chuck assembly and a front chuck assembly which can move along the Y axis are hung on the side hanging frame, a centering follow-up mechanism is arranged on the supporting frame, a laser cutting assembly which can move along the X axis and the Z axis is arranged on the portal frame, and an automatic material receiving frame is arranged in front of the portal frame. The automatic material receiving frame comprises a bottom frame, a sliding frame arranged on the bottom frame in a front-back sliding mode, a displacement driving mechanism, a support, a vertical frame, a material receiving plate, an overturning driving air cylinder, a lifting mechanism and a discharging table. According to the pipe cutting machine capable of automatically receiving the materials, the material receiving plate on the automatic material receiving frame is ingeniously designed to be capable of flexibly moving, the sliding frame and related components can be driven to move front and back according to the length of the pipes and the position of the front chuck, the problem of movement interference is effectively solved, long materials, short materials and tailings can be comprehensively and effectively received, and the working efficiency is improved. And the applicability of the equipment is improved.

The embodiment of the application provides a stamping die structure, relates to the technical field of a die, and comprises an upper die, a lower die and a mounting seat. The lower die is rotationally connected with the mounting seat through a rotating shaft, a plurality of forming grooves are arranged on the lower die and are uniformly distributed in the circumferential direction of the rotating shaft, and the mounting seat is provided with a stepping motor for driving the lower die to rotate. The mounting seat is provided with an adjusting device, which comprises an adjusting rod, a driving mechanism slidingly arranged on the upper die, a first driving rod, a second driving rod arranged on the lower die, a third driving rod arranged on the mounting seat and a return spring. When the upper die descends, the first driving rod drives the second driving rod and the third driving rod in sequence, so that the adjusting rod is inserted into a corresponding forming groove and rises to a predetermined height to limit the forming depth. The application realizes accurate adjustment of the forming depth, has a compact structure and is high in automation degree.

The utility model relates to a laser welding device which is used for welding a splicing seam of a door ring splicing piece and comprises a plurality of welding units, each welding unit is provided with two parallel gantry supports, a cross beam is arranged on the supports, a first displacement assembly is arranged on one side of the cross beam, and the first moving end of the first displacement assembly moves in the direction of the cross beam and is connected with a second displacement assembly; the second moving ends of the welding units move in the direction perpendicular to the horizontal plane, the two laser welding guns are connected with the two second moving ends respectively, the two laser welding guns in the same welding unit move in the opposite directions, the multiple welding units are sequentially arranged in the first direction, and the laser welding guns in the adjacent welding units move in the opposite directions. According to the laser welding device, through the structural combination, movement interference among the laser welding guns is effectively avoided, the multiple welding units can synchronously weld multiple abutted seams, and the welding efficiency and the system collaboration are improved.

This disclosure provides a height-adjusting structure and electronic device for adjusting the height of a foot pad. The height-adjusting structure includes a linkage mechanism for driving the foot pad to rise or fall. The linkage mechanism includes: a gear set for linkage with the hinge shaft of the electronic device; a transmission link, the first end of which is meshed with the gear set, thereby reciprocating linearly along a first direction under the meshing transmission of the gear set; and a foot pad movement component, linked to the second end of the transmission link and the foot pad, configured to reciprocate linearly along a second direction under the drive of the reciprocating linear motion of the transmission link, thereby synchronously driving the foot pad to rise or fall. When this height-adjusting structure is applied to electronic devices, especially laptops, it can better maintain the overall appearance of the laptop and effectively solve the motion interference problem during the opening and closing of the laptop's display.
