5results about How to "Guaranteed thickness accuracy" patented technology

The alkaline electrolyzed water coating die head comprises an upper die, a lower die and a gasket which is located between the upper die and the lower die and used for adjusting the thickness, the upper die, the lower die and the gasket are connected into a whole through a die locking screw, a die lip and a die lip gap adjusting mechanism are arranged at the front end of the upper die, and an extrusion channel is formed between the front portions of the upper die and the lower die. The die is characterized in that the lower die is provided with a feeding channel, the rear end of the feeding channel penetrates through the rear side face of the lower die, a first-stage buffer groove is formed in the top face of the front portion of the lower die in the breadth direction, and the bottom of the first-stage buffer groove is communicated with the front end of the feeding channel; an exhaust hole is vertically formed in the upper die above the first-stage buffer groove in a penetrating manner, and a second-stage buffer groove arranged in the breadth direction is formed in the top surface, located on the front side of the first-stage buffer groove, of the lower die. The coating thickness precision of the extrusion channel in different breadth directions can be guaranteed, air mixed in raw materials is discharged, and bubbles are eliminated.

The application discloses a method for correcting the first-pass roll gap zero point of a heavy plate finishing mill, which comprises the following steps: S1, variable selection, selecting variables related to the correction of the first-pass roll gap zero point of the heavy plate finishing mill from historical data; S2, performing data cleaning and feature extraction on the variables selected in the step S1; S3, using a random configuration network algorithm to establish a model for correcting the first-pass roll gap zero point of the heavy plate finishing mill; and S4, using the model for correcting the first-pass roll gap zero point of the heavy plate finishing mill established in the step S3 to set the first-pass roll gap zero point correction value. The application is based on a large number of effective historical data related to the setting of the roll gap zero point correction value, and uses the random configuration network algorithm to correct the first-pass roll gap zero point of the heavy plate finishing mill after the gauge change in the finishing process of the heavy plate finishing mill, so that the thickness accuracy of the slab is improved.

According to the technical scheme, the proton exchange membrane surface base layer coating die head comprises a left die body, a right die body and a gasket located between the left die body and the right die body which are vertically arranged, the left die body, the right die body and the gasket are connected into a whole through die locking screws, and a buffer groove is formed in the middle area of the inner side face of the right die body in the breadth direction. The gaskets are distributed on the upper portion, the left side and the right side of the buffer groove between the two die bodies, a feeding channel is formed in the middle of the top face of the right die body, the feeding channel penetrates into the right die body and then is communicated with the middle area of the buffer groove, and exhaust holes are vertically formed in the front side and the rear side of the top face of the right die body. The front exhaust hole and the rear exhaust hole are communicated with the top faces of the left end and the right end of the buffer groove respectively, an extrusion channel is formed between the two die bodies below the buffer groove under the guidance of the gasket, the thickness of the extrusion channel corresponds to the thickness of the gasket, and a die lip and a die lip gap fine adjustment mechanism are arranged at the lower end of the left die body. According to the invention, the coating thickness precision of the extrusion channel in different breadth directions can be ensured.

This invention discloses a prefabricated wall panel and its manufacturing process, relating to the field of prefabricated building technology. The wall panel includes a concrete slab and a steel mesh embedded within the concrete slab. The steel mesh is composed of multiple horizontally and vertically interwoven steel wires, with both ends extending beyond the concrete slab to form exposed connection ends. During manufacturing, the steel mesh is precisely fixed in a predetermined position within a mold using a mechanical locking method. Concrete is then poured, and after curing and demolding, the wall panel with exposed steel wires at both ends is obtained. This invention facilitates on-site assembly and welding by extending the steel wires at both ends of the steel mesh beyond the panel. Simultaneously, the mechanical locking method solves the problem of easy displacement of the steel mesh during pouring, significantly improving the production efficiency and positioning accuracy of the wall panel, making it suitable for industrial mass production.
