The present application relates to the technical field of punch dies, and particularly relates to a scratch-proof positioning punch forming mechanism for a metal rack of a powder packaging machine, which comprises a base, a top plate fixedly connected to the top of the base through a plurality of guide struts, a punch plate slidingly connected between the guide struts, a punch convex die and a punch concave die detachably installed at the bottom of the punch plate and the top of the base respectively, and a scratch-proof punch assembly provided at the top of the punch plate and capable of flexibly pre-pressing the metal rack first, then instantaneously impacting and punching, and then rigidly re-pressing and holding pressure. The present application realizes three-stage forming of a plate through linkage of the punch assembly, avoids rigid scratching through elastic pre-pressing, reduces frictional damage through instantaneous impact, stabilizes accuracy through holding pressure and re-pressing, and forms double scratch-proof protection through automatic oiling of the oiling assembly, so as to protect the plate surface finish and plating layer, and improve the degree of automation and the punch quality.

The utility model relates to the technical field of vehicle engineering, in particular to a vehicle body and a vehicle. The vehicle body comprises a bumper, a bumper shell, a buffering piece and a radar assembly, the bumper shell and the bumper are arranged at intervals, the buffering piece and the radar assembly are arranged between the bumper shell and the bumper, the radar assembly is connected with the bumper shell, the buffering piece is connected with the bumper, and at least part of the buffering piece is located between the radar assembly and the bumper. Therefore, when a vehicle is impacted, the bumper deforms under the action of the impact force of the bumper shell, and in the deformation process of the bumper, part of the buffering pieces can make contact with the bumper, part of the impact force of the bumper shell is absorbed, and the deformation amount of the bumper shell is counteracted. Through the design, the deformation amount of the bumper shell can be reduced during vehicle collision, so that the risk that the radar assembly is damaged by deformation of the bumper shell is reduced, and the radar assembly is protected through the buffer piece.

This disclosure relates to the technical field of shaft workpiece machining. One embodiment of this disclosure provides a hydraulic milling machine with dimensional correction after quenching, comprising: a frame and a moving column, the moving column being disposed on the frame; a clamping and fixing assembly being disposed on the frame; and a machining assembly being disposed on the moving column. The clamping and fixing assembly includes a pair of moving frames, which are horizontally linearly driven to be connected to both sides of the frame. A transmission sleeve, driven by electricity, is disposed on one side of each moving frame, and the transmission sleeves are located on the same axis. A boss is provided on the surface of the frame. This technical solution solves the technical problem in the prior art where milling force and the release of residual internal stress in the workpiece exacerbate deformation during machining, leading to a deviation in the accuracy of the machined surface.

The utility model relates to the technical field of silicon carbide, and concretely relates to a drying jig of silicon carbide ceramic pipe type membrane, which comprises a support frame, a first support plate and a second support plate arranged on the support frame, a connecting pipe connected to the first support plate and used for connecting a hot air conveying device, a driving component connected to the first support plate and the second support plate, and a plurality of silicon carbide hollow pipes connected to the driving component. The utility model sets the silicon carbide hollow pipe with an axial through structure as the drying jig of the workpiece. The silicon carbide hollow pipe can be driven by the driving component to rotate at a constant speed. Meanwhile, controllable warm air is continuously input at the end of the silicon carbide hollow pipe to uniformly dry the blank in the silicon carbide hollow pipe during rotation, so that the deformation caused by gravity can be offset, the qualified rate of the product is improved, and the drying speed is improved through the multi-path heat conduction of convection and radiation.

This application discloses a vehicle projection display control method and apparatus, a projection image processing control method, an automobile, equipment, and a storage medium. It determines, at least based on real-time collected vehicle motion data, the expected relative pose change of the vehicle relative to the target road surface at the projection moment; calculates image geometric transformation parameters at the projection moment based on the expected relative pose change, these parameters being used to offset projection offset caused by vehicle motion; performs a reverse geometric transformation on the original projection image based on the image geometric transformation parameters to generate a compensated projection image at the projection moment; and controls the projection module to project the compensated projection image onto the target road surface. By using sensors to perceive the vehicle's own motion posture in real time and using this data to proactively and inversely adjust the projection image size, the projected content remains stable on the target projection plane.
