The utility model discloses a yunker jar siphon pipe manufacturing frock relates to high -speed paper machine technical field, include: guide sleeve, three step holes are arranged to guide sleeve along the axial direction, and are used for the positioning of the end of siphon pipe, middle part and bolt respectively, positioning ring, the positioning ring sets up in the top of guide sleeve, is used for the concentricity of the bolt body with guide sleeve is restricted, fixture positioning surface, fixture positioning surface sets up in the outside of guide sleeve, the utility model provides technical scheme in, three step holes are arranged to guide sleeve, and are respectively end minimum hole, intermediate free hole and upper positioning hole, and are used for the end position of siphon pipe, allow middle deviation and place bolt and ensure its concentricity with siphon pipe respectively. This multistage structure design makes the positioning in the drilling process more accurate, and the consistency and accuracy of drilling position are improved greatly.

The utility model relates to special equipment for punching and processing low-smoke halogen-free trunkings, which comprises a rack, a conveying device, a side stamping die and a bottom stamping die are arranged on the rack, the conveying device is used for conveying processed products, the side stamping die is used for transversely stamping the processed products, the bottom stamping die is used for vertically stamping the processed products, and the bottom stamping die is used for vertically stamping the processed products. The side stamping die comprises a hydraulic cylinder, a die holder, a male die and a female die, an elastic side pressing mechanism is arranged between the male die and the female die, and a lower material pressing mechanism is arranged above the female die; the elastic side pressing mechanism is installed on one side of the male die in an elastic telescopic mode, when the hydraulic cylinder pushes the male die and the female die to be matched for stamping a machined product, the elastic side pressing mechanism presses the machined product, and the lower material pressing mechanism presses the machined product to be fixed to the female die. According to the utility model, the problems of deformation, multiple burrs and the like which are easily generated when the low-smoke halogen-free trunking is punched are effectively avoided.
