Embodiment 1

[0035] like Figure 1 to Figure 5 , a movable working cylinder nylon sintering molding machine, including a forming machine frame 10, two working cylinders 20 arranged side by side, a laser vibrating mirror scanning device 31 and a powder spreading device 32 arranged above the working cylinders.

[0036] A working cylinder is a movable working cylinder that can be moved into and out of a working position. The working position of the working cylinder is as figure 1 Cylinder position on the left.

[0037] In order to enable the cylinders to move into and out of the working position, each cylinder is placed on a cylinder moving frame 40 . The working cylinder moving frame is a frame structure, and the bottom surface of the working cylinder moving frame is provided with a walking roller 41; Composed of beams, the width d on both sides of the working cylinder bracket is smaller than the width D of the working cylinder. The working cylinder moving frame is provided with a workin...

Abstract

The invention relates to a nylon sintering molding machine with a movable working cylinder, which includes a forming machine frame, a movable working cylinder capable of moving in and out of a working position, a laser vibrating mirror scanning device, and a powder spreading device; the working cylinder is placed on a moving cylinder frame , the moving frame of the working cylinder can carry the working cylinder into and out of the frame of the forming machine; the frame of the forming machine is provided with a vertically reciprocating lifting hook plate of the working cylinder; when the lifting hook plate of the working cylinder moves upward, it will The working cylinder is lifted to the working position, and the working cylinder is placed on the moving frame of the working cylinder when the lifting hook plate of the working cylinder moves downward; The cooling and warm-up time in the machine can significantly improve the working efficiency of the nylon sintering machine; the use of double working cylinders or multiple working cylinders can further improve the efficiency; the operation of taking out the finished product and cleaning the working cylinders in the removed working cylinders is also more efficient. Convenient and safe.

Description

technical field [0001] The invention belongs to laser rapid prototyping equipment, in particular to a nylon sintering molding machine with a movable working cylinder. Background technique [0002] At present, the application of laser rapid prototyping equipment (SLS-RP) is developing rapidly, and the forming powders used for SLS-RP new product models include polystyrene (PS), acrylonitrile / butadiene / styrene (ABS), The prototype products made of these two powders have low strength, poor toughness, and are easily damaged. They cannot be directly used for product assembly, interference inspection and performance testing. They must be post-treated with dipping (resin) and heat-cured to improve toughness use, the process is complicated and the cost is high. The SLS-RP technology of nylon powder has the characteristics of excellent sintering and forming properties, high product strength, and good toughness. Products produced by nylon powder SLS-RP technology can pass strict perf...
