Two chuck positioning pins are arranged on the connector riveting jig positioning chuck, and a pressure head positioning pin and a connector riveting jig pressure head are arranged on the connector riveting jig positioning chuck. The rivet pressing device is simple in structure, safe, reliable and high in appearance quality, and the rivet pressing efficiency is greatly improved.

This application relates to the field of lithium battery manufacturing equipment technology, and in particular to a cell module extrusion and tape-making device, comprising: a base, two sets of end extrusion mechanisms, two sets of support mechanisms, and a middle extrusion mechanism; the two sets of end extrusion mechanisms are spaced apart on the base along a first direction; the support platforms of the two sets of support mechanisms are arranged on the base along the first direction and located between the two sets of end extrusion mechanisms. When the middle extrusion mechanism is located between the two support platforms, each support platform carries a first cell assembly, and the two sets of end extrusion mechanisms cooperate with the middle extrusion mechanism to extrude the first cell assembly; when the middle extrusion mechanism is away from the two support platforms, the two support platforms cooperate to carry a second cell assembly, and the two sets of end extrusion mechanisms cooperate to extrude the first cell assembly. By controlling the position of the middle extrusion mechanism, it can be applied to cell assemblies of various lengths without the need for additional replacement of support components, thereby improving the assembly efficiency of the cell assembly.

The present invention discloses a plastic film unfolding frame, which is mainly composed of an opener, a cutting knife, a cutting knife support column, a truncated cone unfolder, an air inlet pipe, a support frame, a reeling roller and a reeling roller. The film unfolding frame is arranged in a straight line, the cutting knife is located in the middle of the opener, the opener is tongue-shaped, the opener is fixedly connected to the truncated cone unfolder, an air hole is opened at the front end of the opener, an air hole is opened on the surface of the truncated cone unfolder, the truncated cone unfolder is fixed on the support frame, a slide rail is arranged on the support frame, and the air inlet pipe is connected to the rear of the unfolder. The reeling roller is located in front of the opener and parallel to the opener, guiding the plastic film to enter the unfolding frame, and the purpose of blowing open the double-layer film can be achieved by ventilation through the front end air hole. The plastic film unfolding frame of the present invention can ensure that the strokes of various parts of the film are the same during the unfolding process, and at the same time, the contact area between the film and the unfolding frame is reduced by using the air film, so as to avoid problems caused by the film being pulled during the process, thereby improving the quality level of the film.

The constant-liquid-level low-pressure casting device without the liquid rising pipe comprises a double-chamber heat preservation furnace, the double-chamber heat preservation furnace comprises a liquid rising chamber and a pressurizing chamber, a communicating channel is arranged between the liquid rising chamber and the pressurizing chamber, and a control assembly used for controlling opening and closing of the communicating channel is arranged on the communicating channel. A first heater and a second heater are arranged at the bottom of the liquid lifting chamber and the bottom of the pressurizing chamber respectively, a feeding port, a pressurizing pipeline and a pressure relief pipeline are arranged on the pressurizing chamber, and a bypass assembly used for adjusting the pressure of the liquid lifting chamber is arranged on the upper side of the liquid lifting chamber. And the nitrogen supply and control system comprises a nitrogen making machine, a control valve group and a control system for controlling the control valves. The invention further provides a casting method based on the device. The problems that in the filling process of molten metal, molten metal fluctuates greatly along with pressurization and pressure relief, oxide skin is generated between the molten metal and a furnace body, the quality of the molten metal is affected, the filling speed is unstable, and the gas entrapment phenomenon of products is caused are solved.

The utility model discloses a surging simulation device for a super breast surgery, which comprises a simulation block, a handle and a plug assembly, and is characterized in that a simulation cavity for an experiment is arranged in the simulation block; the simulation cavity is at least communicated with a first connecting channel used for exhausting, a second connecting channel used for being connected with a handle, a third connecting channel used for being connected with a plug assembly and a fourth connecting channel sealed by a soft film, the first connecting channel is connected with an exhaust outlet, and the first connecting channel and the simulation cavity extend in the same direction; and the top of the inner pipe wall of the first connecting channel is flush with the top of the inner wall of the simulation cavity. According to the utility model, the first connecting channel and the simulation cavity extend in the same direction, and the tops of the first connecting channel and the simulation cavity are flush, so that bubbles in the simulation cavity can be conveniently and completely discharged during pre-filling, and unnecessary interference to experimental data due to the fact that the bubbles are left in the simulation cavity is avoided.

The utility model discloses a kind of operating system simulation footrests, including base, the base has two, the upper side of base is equipped with three horizontal bearing seats one of even distribution, two transversely distributed footrest uprights are rotatably connected between three horizontal bearing seats one of transversely adjacent, the upper end of footrest upright is rotatably connected with pedal by pivot two, still include footrest steering mechanism;Footrest steering mechanism: it includes pivot three, adjusting block, pivot four, main and auxiliary footrest connecting rod and adjusting assembly, this operating system simulation footrest, compatible multiple driving mode realizes aircraft footbrake and steering function, can satisfy the training demand of simulator, trainer, and device internal zero-gap design guarantees force feeling, stroke and installation aircraft keep consistent, while device itself selects healthy environmental protection, reliable device, equipment surface treatment, process method uses national military standard technology, environmental protection durable.
