Design of safety hoisting/precision mould Department: Xie Tianyi. Purpose in order to standardize the design process, facilitate the safe transportation, processing and installation of mould parts, eliminate potential safety hazards and improve product quality, formulate this operation specification.
Second, the scope of application is applicable to mold design and process layout personnel.
Three, the workpiece design hoisting hole conditions ①, need mechanical hoisting, workpiece clamping processing for many times (Such as inserts, sliders, etc)
On the premise that the structural design requirements are guaranteed, the bottom surface should be designed with screw holes for the code plate and the top surface should be equipped with lifting holes;
(2) workpieces with parts weighing more than 10 kg;
(3), length, width, height at the same time have a size greater than 100, another size greater than 200 workpiece; (4) for the standard mold frame above 3030 (Including 3030)All templates must be equipped with hoisting screw holes;
(5) standard formwork under 3030, fixed and moving formwork (That is, the and B boards referred to in the dragon standard)And the needle plate and the bottom needle plate must be equipped with lifting holes (No lifting holes below).
6. For workpieces with a single piece of material weighing more than 750, the supplier shall process the lifting hole and return it to the factory. The position and size of the lifting hole shall be determined by the attached drawings. (Mainly for the main material). 7. Template (Long)1000X600 (Wide)
And the above dimensions, the supplier needs to process the lifting hole back to the factory, the location and size of the lifting hole are determined by the drawing. (Mainly for standard formwork templates and scattered plates).
⑧ For workpieces with a weight of more than 20KG of single beryllium copper material, the supplier shall return to the factory after processing the hoisting hole. The position and size of the hoisting hole shall be determined by the attached drawings. NJPE-
China's leading precision mold processing factory has advanced equipment capability, innovative research and development strength, strong financial strength and strong production capacity.
