Grinding device for wooden door manufacturing

The invention provides a grinding device for wooden door manufacturing. The grinding device for wooden door manufacturing comprises a bracket, an overturning assembly, a limiting assembly, a grindingassembly and a material moving assembly used for driving the grinding assembly to move horizontally. The bracket comprises a left side plate, a right side plate and a top plate of a cuboid structure.The material moving assembly comprises a first feed assembly and a second feed assembly. The overturning assembly comprises a first material overturning assembly and a second material overturning assembly. The first material overturning assembly and the second material overturning assembly are of the same structure and each comprise a rotary tube, a clamping assembly located the end, close to thetop plate, of the rotary tube and a rotating assembly used for driving the rotary tube to rotate in the axial direction of the rotary tube. The grinding device has the beneficial effects that workpieces can be turned over through the overturning assembly and can be limited through the limiting assembly, and the situation that the workpieces are scrapped due to not being limited; the surface and the two sides of each workpiece can be ground through the grinding assembly, and the grinding device can also conduct processing on wood bits produced during grinding.

Manufacturing process for plugging conductive holes of circuit board with resin

The invention discloses a manufacturing process for plugging conductive holes of a circuit board with resin, which comprises the following steps: A) carrying out plated through hole and electroplating treatment on a circuit board substrate which is provided with conductive holes; B) carrying out windowing treatment on conductive holes of the circuit board substrate which is electroplated, and adhering a dry film to transfer the printed picture; C) electroplating the conductive holes of the circuit board which is provided with the dry film; D) filling resin into the conductive holes so as to plug the conductive holes, and baking the circuit board at low temperature after the conductive holes are plugged; E) removing the remained resin through polishing way; F) removing the film of the circuit board after being polished; and G) and baking the circuit board at high temperature after the film is removed. The process not only can solve the problem that the air bubbles are easy to produce by directly filling ink or other anti-corrosion materials, but also greatly reduces the polishing difficulty; and during the hole plugging process of the conductive holes of the circuit board, the circuit board is only required to be polished for one time, so not only the efficiency is improved, but also the cost is reduced.

Pipe double-end internal and external chamfering processing apparatus

The invention relates to the technical field of pipe processing equipment, and specifically discloses a pipe double-end internal and external chamfering processing apparatus. The apparatus comprises a feeding mechanism and a pipe double-end internal and external chamfering processing mechanism. The feeding mechanism comprises two feeding devices oppositely arranged on the left and right sides. Each feeding device comprises a feeding plate and a bearing platform, and the bearing platform is provided with an initial falling point from which place the pipe falls. At an initial state, the portion, acting on the pipe, at the front end of each feeding plate is located behind the initial falling point. A front limiting top plate limiting the front part of the pipe is arranged at the position close to the front end of each bearing platform. A discharging plate through which the pipe is supported and discharged is arranged at the front end of each bearing platform. The pipe double-end internal and external chamfering processing mechanism comprises two internal and external chamfering processing devices which are oppositely arranged. Each internal and external chamfering processing device comprises a polishing means including an inner polishing head and an outer polishing head. A motor is arranged on the side, opposite to the pipe, of each polishing means. The pipe double-end internal and external chamfering processing apparatus is safe and stable in operation, high in efficiency and high in fluency, and has good positioning and processing effects.
