The pump body control panel arranged on the distribution pump main body is used for controlling starting of the extraction pump, fluid in the material storage box is directly pumped into the distribution pump main body through the extraction communicating pipe, the pumped fluid is directly injected into the pre-storage control measuring cup through the distribution pump main body, and the pre-storage control measuring cup has the effect of serving as a quantitative cup; a fixed amount of fluid is pre-stored in the pre-storage control measuring cup, after the pre-storage control measuring cup is filled with the fluid, starting of the injection pump is directly controlled through the pump body control panel, the communicating transmission pipe extends into the bottom end of the interior of the pre-storage control measuring cup, and the fluid in the pre-storage control measuring cup is injected through the injection needle tube.

The utility model relates to the technical field of blow molding air pipe fitting machining, and discloses a blow molding air pipe fitting rim charge cutting device which comprises a machining table and a cutting rope, a fixing plate is fixedly connected to the rear side of the top of the machining table, and electric telescopic rods are fixedly connected to the left side and the right side of the top of the machining table. And clamping mechanisms are arranged on the top of the fixing plate and the front side of the top of the machining table, the clamping mechanisms are used for clamping blow molding air pipe fittings, and replacing mechanisms are arranged on the tops of the two electric telescopic rods and used for clamping and rapidly replacing cutting ropes. The hydraulic rod extends to drive the pushing disc to move downwards, the spring pushes the connecting plate and the rubber ball to clamp the pipe fitting through elastic force, the spring is reset and loosened when the hydraulic rod contracts, the self-adaptive clamping effect on the blow molding air pipe fitting is achieved, the self-adaptive clamping device can be compatible with pipe fittings of different specifications, clamping stability is guaranteed, displacement is prevented, pipe fitting damage caused by too large pressure is avoided, and the service life of the blow molding air pipe fitting is prolonged. And the machining precision and the yield are improved.

This utility model provides a quick-change stamping head for a sheet metal stamping forming device, including: a stamping electric cylinder, a head-changing component, and a support base. A head-changing component for quick head replacement is provided on the inner side of the lower end of the two sets of support frames. The head-changing component includes a motor and a stamping head. The head-changing component is embedded inside the two sets of support frames. A protective shell for protecting several sets of stamping heads is provided on the outer side of the motor. Compared with the prior art, this utility model has the following advantages: When the stamping head needs to be replaced, the system pauses the operation of the stamping electric cylinder, the motor automatically drives the rotary table to rotate 180 degrees, and switches the preset spare stamping head to the working position. The clamping seat achieves quick positioning and locking through the mechanical limit of the inner groove. After replacement, the side pressure limiting seat and the guide seat work together to ensure the stability of the stamping force transmission, and the cylinder head releases uniform pressure with the cooperation of the lower connecting column, thereby quickly completing the stamping head replacement.
