This invention discloses a high-toughness, fracture-resistant cold-drawn steel profile, comprising a cold-drawn steel body, the upper surface of which is respectively pre-set with an upper slot one and an upper slot two. By pre-setting corresponding overlapping slots on the upper and lower top and bottom surfaces of the cold-drawn steel body, the two sets of slots are staggered to achieve stable limiting overlap between adjacent sets of cold-drawn steel bodies, ensuring that misalignment is avoided when the two sets of cold-drawn steel bodies are stacked. Combined with the limiting insertion between the convex inserts on both sides of the cold-drawn steel body and the U-shaped mounting frame, precise lateral positioning and installation of the cold-drawn steel body is achieved. Multiple sets of arranged threaded posts further stabilize the two laterally inserted sets. This invention solves the problems of poor impact resistance and low toughness of existing cold-drawn steel profiles, and the tendency for misalignment and damage caused by friction and collision between steel profiles during transportation, thus improving the impact resistance and toughness of cold-drawn steel profiles.

The utility model discloses a motor housing and a waterproof motor using the same, and the motor housing comprises a main housing which is provided with an accommodating cavity; the outlet box is integrally injection-molded on the main shell, and the outlet box and the main shell jointly form an opening communicated with the accommodating cavity; the metal layer is arranged on the inner wall of the accommodating cavity; the cover plate is suitable for being connected with the main shell in a matched mode to form a sealing cover for the opening; and a concave-convex inserted waterproof structure is formed between the cover plate and the matching surface of the edge of the opening.

The utility model provides a high-precision limit in-mold asynchronous die-cutting machine, which relates to the technical field of die-cutting machines and comprises a bottom plate, support columns are fixedly connected to the top of the bottom plate and close to four corners, a top plate is fixedly connected to the tops of the support columns, a limit groove is formed in one side wall of each support column, and the limit grooves are fixedly connected to the top plate. Grooves are formed in the top, close to the two ends, of the bottom plate. According to the utility model, through the innovative design of the convex embedding plate and the positioning assembly, the mold plate (including the cutter and the groove plate) is embedded into the convex groove through the trapezoidal plate, and the second bidirectional screw rod and the clamping plate are utilized to realize rapid clamping and fixing. When the die is replaced, only the convex insert plate needs to be pulled and matched with rapid locking of the rotating rod and the limiting block, and the replacement efficiency can be improved. And meanwhile, the center can be automatically positioned through two-way screw driving and a trapezoidal structure of the positioning assembly, the materials can be aligned to the die plate through cooperation with the limiting assembly, manual adjustment errors can be greatly reduced, and the die cutting quality is improved.
