The invention relates to a puncher; a piercing punch (2) is unmovably and loosely inserted in a cylindrical cover (1) having a one-end opening hole (10) while a tip end face (20) projects from the one-end opening hole (10). A cylindrical stripper (3) is provided between the cover (1) and the piercing punch (2) while the stripper (3) can be pulled out from the one-end opening hole (10). The stripper (3) is made to project more than the piercing punch (2) from the one-end opening hole (10) by an urging means (4). Then, pushing into the stripper (3) against the urging force of the urging means (4) makes the distal end face of the piercing punch (2) project from a through hole (30) bored at the projecting end of the stripper (3). A come-out prevention means for preventing the stripper from coming out from the cover is provided at the cover detachably.

The invention provides a waste gas treatment device for a nitriding furnace. The waste gas treatment device comprises a device body of which the upper end is open, wherein a combustion chamber penetrating up and down is formed inside the device body; a metal ring which is hollowed out or provided with an air vent is arranged at the bottom of the combustion chamber; the device body is further provided with a pressure retaining valve which is capable of keeping the desired pressure for waste gas combustion through exhausting or shutdown of exhausting; the waste gas of the nitriding furnace is fed into the combustion chamber and below the metal ring from the bottom of the device body through a waste gas transmission pipeline, and the gas outlet of a gas pipeline is communicated with the combustion chamber and below the metal ring from the bottom of the device body; the gas out of the gas pipeline is ignited by an ignition device to heat the metal ring, the metal ring heats the combustion chamber so that the temperature in the combustion chamber is higher than the ignition temperature of the waste gas, and therefore, the waste gas transmission pipeline is communicated with the interior of the combustion chamber to burn the waste gas and emit the waste gas after combustion through a pipeline; and consequently, enough temperature and pressure in the combustion chamber are guaranteed to sufficiently burn the waste gas and avoid residual.

The invention discloses a pressure maintaining device for cable assembly of an earphone shell, which comprises a housing positioning component and a pressure maintaining component; the pressure maintaining component includes a pressure maintaining air bag, a slide control mechanism, an air bag positioning mechanism and a fluid control component; The pressure air bag includes a pressure retaining part, and the fluid control component is connected with the pressure retaining air bag for delivering fluid to the pressure retaining air bag, so that the pressure retaining part expands from the original state to the pressure retaining state; the outer diameter of the pressure retaining part in the original state Smaller than the outer diameter of the assembly opening of the earphone housing; and when the earphone housing is in a pressure-holding state, press the cable against the inner wall of the earphone housing. By using the inflatable pressure-holding air bag to keep the pressure continuously after the headphone cable is installed, it can fully exert pressure on the cable in a small space, and the final cable bonding effect is good, and the efficiency and stability of the earphone assembly Sex has improved significantly.

The invention relates to a printing machine. The printing machine comprises a workbench, a bearing plate, a fixing frame, a pressing mechanism and a driving mechanism; the bearing plate is arranged on the workbench; the fixing frame comprises a first frame and a second frame which is fixedly connected with the first frame; the pressing mechanism comprises an air pump, an air delivery pipe and an inflation thin film; the air pump communicates with the air delivery pipe; the inflation thin film communicates with the air delivery pipe and is movably arranged in the fixing frame; the driving mechanism comprises a fixing block, guide rails and a driving motor; the guide rails are fixedly arranged on the workbench; and the fixing block is arranged on the guide rails in a sliding manner. The air pump is used for inflating air for the inflation thin film for enabling the inflation thin film to evenly apply pressure on printing stock on the bearing plate; and the inflation thin film is limited by the fixing block and the fixing frame for being prevented from being exposed, so that the inflation thin film can fully apply pressure on the printing stock, printing ink can be evenly printed on the printing stock, and the printing effect is better.

The invention provides a multi-cavity I-beam and a high-precision soft mold forming and defect control method thereof. Aiming at structural features of multiple cavities, multiple molded surfaces, unequal thickness of marginal / web plates and high precision of molded surfaces inside cavities, silicone rubber soft mold pressurization is adopted to achieve the overall co-curing molding of the I-beamwith a complex structure. The multi-cavity I-beam comprises at least two main beams and at least six secondary beams, the main beams and the secondary beams are in the same plane, the main beams are not intersected with each other, the secondary beams located between the main beams are used for connecting the main beams, and the secondary beams located outside the main beams are used for connecting with the outside; equitable distribution of pressure in the X / Y / Z direction is achieved by adopting silicone rubber soft mold process gap compensation design, and the problem of unequal thickness pressurization of the marginal / web plates is solved; an internal soft-external hard pressure equalization design method is utilized to avoid the pressure deviation caused by uneven expansion of a soft mold, and the dimensional accuracy and internal defects of the molded surfaces inside the cavities are improved.

The invention discloses a flexible pressure application tool for controlling the assembly damage of the front edge of an unmanned aerial vehicle, comprising: a first support block, a second support block, a screw, a wire thread sleeve, a screw rod, a first nut, a second nut, and foam glue and soft foam. The first support block is connected with the assembly tooling; the second support block is connected with the first support block by screws; the wire screw sleeve is installed at the corresponding position of the first support block and the second support block; the screw rod is installed on the wire screw The two nuts are installed on the screw rod; the soft foam is attached to the lower end of the screw rod through foam glue. Except for the support block which is machine-added, all finished parts are used as tooling components, which are low in cost and easy to assemble; the screw has an adjustable function, which makes the tooling flexible and can adapt to different airfoils and different sizes; the tooling is in contact with the leading edge The position adopts a soft foam structure, which can effectively control the structural damage of the leading edge and protect the leading edge while realizing the bonding and pressure of the ultra-thin leading edge and the rib.

The invention provides an environmentally friendly intelligent production device for high-density hollow bricks, and relates to the technical field of intelligent production of hollow bricks. The environmentally friendly and intelligent production device for high-density hollow bricks includes a slide rail, the top of the slide rail is slidably connected to a placement plate, a shaping frame is placed on the top of the placement plate, and landing gear is fixedly installed at the front and rear ends of the shaping frame , the inside of the shaped frame is slidably connected with a connecting rod, the periphery of the connecting rod is slidably connected with a hollow column, the bottom end of the connecting rod is fixedly mounted with a slider, and a groove is opened inside the hollow column.
