The invention relates to a two-way blank pressing drawing and coining integration die. The two-way blank pressing drawing and coining integration die comprises an upper die and a lower die, wherein the two-way blank pressing drawing and coining integration die is characterized in that the upper die comprises an upper die plate, an upper die base plate is fixed on the upper die plate, an upper die material pressure plate is arranged on the lower surface of the upper die base plate, an upper die material pressure spring is arranged between the upper die material pressure plate and the upper die plate, a punch is arranged on the lower surface of the upper die plate, and the lower surface of the punch is a workpiece forming surface; the lower die comprises a lower die plate, a first lower die base plate and a second lower die base plate are fixed on the lower die plate, a concave die is arranged on the upper surface of the second lower die base plate, a lower die material pressure spring is arranged between the first lower die base plate and the concave die, the upper surface of the concave die is the workpiece forming surface, a lifting pin is arranged in the middle of the concave die, and a lifting spring is arranged between the lifting pin and the lower die plate. The two-way blank pressing drawing and coining integration die has the advantages of being capable of improving forming property of materials, achieving one-step forming workpieces and automatically taking off of the workpieces, and high in workpiece accuracy.

The invention relates to cleaning equipment, in particular to glass cleaning equipment for building. The technical problem to be solved is to provide the glass cleaning equipment for a building, which is capable of realizing automatic cleaning and wiping. The glass cleaning equipment for the building comprises a first rotating shaft, a power mechanism with the two sides of a part thereof being rotationally connected with the first rotating shaft, rotating wheels arranged on the two sides of the first rotating shaft, and a flushing mechanism arranged on the power mechanism. Through cooperation of the power mechanism and the flushing mechanism, the glass cleaning equipment can be automatically moved while glass is cleaned, the working efficiency of people is improved, through cooperation of a detergent adding mechanism and a wiping mechanism, detergent can be automatically sprayed out, the glass is cleaned more cleanly, and then the glass is wiped.

A bend pipe forging die with a springing device comprises a fixed die body and a movable die body, wherein the movable die body is arranged below the fixed die body; a convex die body is arranged on a forging surface of the fixed die body; a concave die body which is matched with the convex die body is arranged on a forging surface of the movable die body; the convex die body is matched with the concave die body to form a forging cavity of which the shape is matched with that of a bend pipe; the springing device is arranged in the movable die body; a downward blind hole is formed in the forging surface of the movable die body; the springing device comprises a first spring arranged at the bottom of the blind hole and a pressure lever arranged on the first spring; the upper end of the pressure lever extends out of the blind hole; the upper part of the pressure lever is a wedge-shaped surface; a through hole is formed in a position, which corresponds to the forging cavity, of the wedge-shaped surface; a push rod which is matched with the wedge-shaped surface of the pressure lever is arranged in the through hole; and a resetting spring is arranged on the push rod. The springing device is arranged in the movable die body, so that a finished bend pipe can be unloaded from the die when stripped from the die; the labor intensity of workers is reduced; and the forging efficiency of the bend pipe is improved remarkably.

The invention provides a tool for wall painting, and relates to the field of decorating tools. The tool for wall painting is exquisite in structure, easy and convenient to operate and good in sealing effect, and the material utilization rate can be increased through automatic control over a piston. The tool for wall painting comprises a handrail, a roller and a connecting assembly. The roller is connected to one side of the handrail through the connecting assembly and is perpendicular to the handrail. The handrail comprises an inner rod body, an outer sleeve body, the piston, a sealing pad, a connecting rod, a suction nozzle and a spray head, wherein the inner rod body is hollow, and one end of the inner rod body is connected with the connecting assembly. When the tool for wall painting is in use, an operator can place the suction nozzle into a paint barrel firstly and pull the outer sleeve body outwards at the same time, so that paint is sucked into the inner rod body; and then the inner rod body or the outer sleeve body is repeatedly waved on a wall in the same direction, so that the paint is sprayed out automatically, and the wall is painted rapidly. By adoption of the tool for wall painting, the utilization rate of the paint is effectively increased, and environmental pollution during construction is reduced.
