Prototype design is an important step to improve the quality of the prototype. Many factors need to be considered, such as the selection of prototype materials, the usability and safety of the prototype structure, the machinability of prototype parts and the convenience of prototype maintenance. These are in the design process. It needs to be thought through as soon as possible. Next, Shenzhen Xiehe Prototype Processing Factory will tell you about the precautions for the production and processing of prototypes.

The selection of prototype materials should not only meet the customer's requirements for product quality, but also consider the cost of the material and its strength within the set period. Of course, it should also be based on the type of prototype, working method, processing speed, main failure mode, etc. factors to select materials. For example: the main failure mode of the punching die is the wear of the cutting edge, so it is necessary to choose a material with high surface hardness and good wear resistance; the punching die is mainly subjected to cyclic loads, which is easy to cause surface fatigue cracks, resulting in surface peeling, then choose Materials with good surface toughness; materials with a particularly low friction coefficient should be selected for deep drawing molds; materials with strong thermal fatigue properties should be selected for die-casting molds due to cyclic thermal stress.

The following points should be paid attention to in the production and processing of the hand board:

(1) The process route of the prototype can be divided into two processing according to the needs of the workpiece. First process the inner wall of the appearance of the prototype, mill the benchmark, and then turn 180. Clamping, processing the outer surface and the position of the button screen. If the outer surface is processed first, and then the inner wall is processed, it is difficult to position and clamp for secondary processing.

(2) If the wall thickness of the prototype is only 1.5mm, it is easy to deform and break when processing the outer surface. If there is, add filler in the cavity that has been processed for support. This avoids processing through-hole parts and then filling with gypsum, otherwise it is difficult to separate the finished product and the filling.

(3) The trimmed surface should be repaired first, the position of the through hole on the surface should be covered, and the whole surface should be processed, and then the through hole processing should be completed by grooving, so as to avoid the uneven tool path and the cutting force when the through hole is processed. uniformity, etc.

4) Remember! The reference truncation angle should be milled out first, so as to avoid the wrong direction of the blank when flipping and clamping.

(5) Note: During the production process, the cutting should be simulated first, and after checking it is correct, the processing should be carried out, and the numerical control processing should be carried out.

The various parts on the rapid prototype should have sufficient strength and rigidity to prevent damage and deformation during use, and the fastening parts should have anti-loosening measures to avoid accidental injury to the operator. It is not allowed to have the phenomenon of scrap or workpiece missiles in the process of processing, which will affect the operator's attention or even injure the operator. In addition, it is necessary to avoid cutting the hands from the burrs of the blanking parts.
