This invention discloses a method for manufacturing 3D display glass and its curved display glass, relating to the field of glass manufacturing technology. A conveying preheating box is attached to one side of the top of a multi-stage temperature control frame. Several pressure-equalizing hydraulic cylinders are equidistantly installed on the top of the conveying preheating box. Pressure-limiting fixing frames are attached to the bottom of the pressure-limiting fixing frames. Inlet and outlet electric slide rails are symmetrically installed at the bottom of the pressure-limiting fixing frames. Inlet and outlet sliding frames are installed at the bottom of the inlet and outlet electric slide rails via slide rail seats. A positioning electric slide rail is embedded at one end of the inlet and outlet sliding frame. A shaping top mold is fitted between two clamping fixing frames. This invention utilizes a combination of pneumatic hot bending, gravity hot bending, shaping hot pressing, and edge correction hot pressing. Furthermore, by using slow heating and slow cooling, along with mold control, the shape of the curved glass can be effectively controlled. Simultaneous operation of pretreatment and forming processes reduces the waiting time required during production.

This invention discloses a ball valve body anti-shrinkage casting module, relating to the field of ball valve body processing. It includes a casting main block, with a first guide post welded internally. The inner wall of the first guide post is lined with paraffin wax. This invention sets up a module by welding the first guide post to the inner wall of the casting main block and correspondingly welding a second guide post to the inner wall of the casting sub-block. One end of the first guide post is designed as a tapered structure. This tapered end can guide and retract the valve core during the initial stage of mold closing between the casting main block and the casting sub-block. Due to the gradual transition characteristics of the tapered surface, the cooperating first and second guide posts simultaneously provide continuous limiting guidance to the valve core within the mold cavity during the closing process of the two modules, preventing the valve core from shifting or misaligning during mold closing, thereby achieving rapid guidance and positioning of the valve core.

The utility model belongs to the technical field of coke oven processing, and particularly relates to a coke oven automatic heating device which comprises an operation platform, two groups of supporting legs are arranged on the upper surface of the operation platform, one ends of the two groups of supporting legs are fixedly connected with a coking furnace, and a coke discharging groove is formed in the lower surface of the coking furnace. The upper surface of the coking furnace is sleeved with a feeding frame, a combustion furnace is arranged on the outer side of the coking furnace, a smoke pipe and a gas pipeline are connected into the combustion furnace in a penetrating mode, a valve body is arranged on the outer surface of the smoke pipe, an output shaft of a small motor drives a rotating shaft to rotate, and the rotating shaft drives a ball installed at the tail end to rotate. The ball body drives the connecting block to rotate, the connecting block drives the two groups of flow baffles to rotate, the rotating shaft drives the flow baffles to realize the switching of gas among different combustion chambers or heating channels, the small motor is improved to realize the automatic switching of the flowing directions of gas, air and waste gas, and the heating process of the coke oven is enabled.
