This application relates to the field of full transfer film technology, specifically disclosing an electroplated metal laser full transfer film with surface texture. The electroplated metal laser full transfer film with surface texture includes a substrate, a release layer, a laser molding layer, an aluminum plating layer, and an adhesive layer. The laser molding layer coating is prepared from acrylic resin, alkyd resin, isocyanate curing agent, hexamethylolmelamine, hydroxyl acrylate, modified filler, leveling agent, defoamer, pigment, and solvent. The modified filler is prepared from nano-alumina, polyethyleneimine, and fumaric acid, with a mass ratio of nano-alumina, polyethyleneimine, and fumaric acid of 1:(0.4-0.6):(0.7-1). This invention effectively improves the surface adhesion of the laser molding layer, reduces the separation of the laser molding layer during hot stamping, and improves the quality of the full transfer film.

This utility model relates to the field of new energy battery technology, and discloses a battery cell and a battery pack. The battery cell has a first direction and a second direction that are perpendicular to each other, and includes: a top cover plate with a positioning groove; an insulating component including a main body and a first protrusion, the first protrusion being located on the side of the main body away from the top cover plate, the first protrusion including a platform body with a clearance groove, the platform body being connected to the main body, the clearance groove penetrating a portion of the platform body along the second direction; and a first positioning post, one end of which passes through the positioning groove and is connected to the top cover plate, and the other end of which is connected to the main body. Along the first direction, the orthographic projection of the first positioning post on the first protrusion is at least partially located in the clearance groove, and the orthographic projection of the first positioning post on the main body is offset from the orthographic projection of the platform body on the main body. The first protrusion is a common location for the insulation component to collapse. Increasing the force exerted by the first positioning post on the insulation component at the first protrusion can reduce the collapse amplitude of the first protrusion and improve the safety and stability of the battery cell.

The utility model discloses an earth rock cofferdam structure for a diversion building, and relates to the technical field of cofferdam construction, the earth rock cofferdam structure comprises two cofferdam main bodies arranged on the upstream and downstream of a river channel, the cofferdam main bodies are transversely arranged in the river channel and fixedly connected with river banks on the two sides of the river channel, and diversion canals are formed in the river banks at the same ends of the two cofferdam main bodies; the diversion canal is communicated with the upstream and downstream of the river channel, and a diversion foundation wall is arranged on the side, close to the cofferdam bodies, of the diversion canal and fixedly connected with the ends, close to the diversion canal, of the two cofferdam bodies. The diversion canal is excavated on the river bank located at the same end of the two cofferdam bodies, the diversion canal guides water flow on the upstream of the river channel to the downstream of the river channel, the diversion canal is formed in the river bank to replace a tunnel, and it is avoided as much as possible that the tunnel is scoured for a long time, collapses and influences a construction site in the cofferdam.

The application relates to the technical field of shoe accessory, in particular to a shoe-pad rear-heel supporting structure and a forming die thereof, which comprises a bottom die, a middle die and a top die, the bottom die is rotationally connected with the middle die, the top die is rotationally connected with the bottom die, the middle die is located between the bottom die and the top die, a placing seat for placing a supporting plate is arranged on the bottom die, a through seat hole for the placing seat to pass through is arranged on one side of the middle die close to the bottom die, a palm-pad protrusion is arranged on one side of the top die close to the middle die, a bottom groove is arranged on the middle die, the through seat hole and the bottom groove are in communication, a surrounding ring is arranged on the middle die, the palm-pad protrusion, the bottom groove, the placing seat and the surrounding ring are enclosed to form a closed cavity for forming a rear palm pad in the state that the bottom die, the middle die and the top die are mutually overlapped, and a locking assembly is arranged on the bottom die. The application has the effect of improving the combination tightness between shoe-pad components.

The invention belongs to the technical field of stamping, and particularly relates to a progressive die stamping device and method for a metastable stainless steel multi-bending component. The device comprises a base, and a blanking unit and a multi-stage stamping die unit which are sequentially arranged on the base, the punching unit comprises a pressing die assembly, a punching die assembly, a pressing die locking mechanism and a punching die locking mechanism. A guide column is arranged on the base, the pressing die assembly and the punching die assembly are in sliding fit with the guide column, the pressing die assembly is used for pressing a progressive die punching metal plate, and the punching die assembly is used for punching the progressive die punching metal plate; the pressing die locking mechanism and the punching die locking mechanism are arranged on the two sides of the base correspondingly, the pressing die locking mechanism is used for locking the pressing die assembly, and the punching die locking mechanism is used for locking the punching die assembly; the multi-stage punching die unit is used for conducting multi-stage punching and blanking on the punched part of the progressive die punching metal plate in sequence. According to the method, high-efficiency, low-cost and batch stamping forming of the low-temperature high-toughness thin-wall multi-bending component is achieved, and the formed part does not need follow-up heat treatment annealing.
