Description

Blowing device of receiving pipe and die discharging system Technical Field The utility model belongs to the technical field of die discharging, and particularly relates to a blowing device of a receiving pipe and a die discharging system. Background In the field of metal stamping processing, a receiving pipe is an important part for receiving the discharge of a die and is used for guiding the stamped parts to be discharged orderly. However, the following technical pain points exist in actual production: the problems of part adhesion and blockage are that blanking oil is needed to assist in the stamping process, so that oil stains remain on the surface of the part and the part has viscosity. When the parts are pushed by air flow in the receiving pipe, the parts are easily accumulated gradually due to the adhesion of oil stains on the pipe wall, and finally the blocking is caused. When serious, the putty can even make the part card at the mould discharge gate, causes the part to warp, the dislocation scheduling problem of mould, finally leads to mould damage or scrap. The maintenance cost and the production efficiency are restricted by frequent blockage faults requiring shutdown cleaning, thus not only affecting the production continuity, but also increasing the manual maintenance cost. In addition, part quality defects (such as scratches and deformation) caused by the plugging material further reduce the product yield. In view of the foregoing, there is a need in the industry for a solution that can effectively prevent sticking and plugging of the internal parts of the receiving tube. Disclosure of utility model Aiming at the technical problems in the prior art, the utility model provides a blowing device and a die discharging system of a receiving pipe, which are used for solving a series of problems caused by adhesion and blockage of internal parts of the receiving pipe in the background art. According to a first aspect of the present utility model, there is provided an air blowing device for a receiving pipe, including a device body, wherein an air blowing portion is provided on the device body, the air blowing portion extends into an inner bottom portion of the receiving pipe at least partially when the device body and the receiving pipe are matched for operation, an air blowing hole is provided on the air blowing portion, and an air blowing direction of the air blowing hole is directed to an outlet of the receiving pipe along an axial direction of the receiving pipe. The air blowing device is arranged at the structural position of the air blowing part, so that air flow of the air blowing hole after the material receiving pipe is matched can directly act on the bottom in the pipe, parts are pushed to the outlet conveniently, stable and uniform air blowing in the material receiving pipe is realized through the arrangement of the air blowing direction, the parts can be blown out smoothly, the risk of collision is reduced, and blocking is avoided. In a specific embodiment, a clamping groove matched with the mouth part of the receiving pipe is formed in one side of the device body.
