Life. Production technology preparation; Preparation of materials; Die parts
13 Different types of molds have different forms of normal injuries; Assembly debugging and trial appraisal.
Sample, but in general, the form of working surface damage is friction 2. The preparation stage of production technology includes the design of mold pattern.
Damage, plastic deformation, cracking, fatigue damage, biting. Rice; Compilation of process technical documents; Material quota and processing
14 There are many methods for surface classification of die parts, which are divided into the formulation of man-hour quota; Mould cost evaluation.
Profile, molding surface and structural surface. 3 process: in the process of mold making, it is directly replaced.
15 molding surface: it directly determines the shape, size, accuracy, performance and assembly relationship of product parts in the mold.
The surface shape, size and accuracy of parts and the production technology related to these surfaces.
The relevant surface of a tone. 4. The process documents of molds mainly include the processors of mold parts.
16 plane processing can be done in shaper, vertical art regulations, mold assembly points and technical regulations, original
Planing and milling shall be carried out on milling machines and planers, and the list of materials, purchased parts and outsourced parts shall be removed. mould
Except for most of the machining allowance on the blank. In terms of production efficiency, technicians should fully understand the structure and working principle of the mold.
Considering the planer planer planed large plane; And the requirements of the case.
Medium-sized planes are mostly planed by shapers; Main contents of small and medium-sized 5-mold process work: 1 preparation of process documents.
Profiles are mostly milled by vertical milling machines. The second part: the design and process planning of the second kind of tools; 3: Processing.
The machining of 17 molding surface is divided into two main steps. The first step is to participate in the mold test and appraisal of technical question 4.
Size processing, using various methods to achieve the characteristics of design drawings 6 mold technology: 1 mold as universal as possible.
Samples require dimensional accuracy and positional accuracy. The second step is to use all machine tools, universal knives, measuring tools and instruments, and reduce them as much as possible.
After grinding and polishing, the molding surface can reach the number of less special second-class tools. 2 in the mold design and manufacture.
Surface roughness and shape accuracy required by design drawings. In practice, "real matching method" and "same boring method" are widely used. three
18 blank mainly considers the following aspects: 1 mold material has relatively centralized manufacturing process guarantee,
2 categories and functions of mould parts 3 quality and progress of mould processing of mould parts, simplifying management and reducing working procedures.
Geometric features and dimensional relationships. Turnaround time.
The blank forms of 19 die parts are mainly divided into: original profiles, 7 die technical and economic indicators: die accuracy and stiffness,
Forged parts, cast parts and semi-finished parts. Mold production cycle, mold production cost and mold production cost
There are four basic ways to cut the original profile: shearing method, sawing method and service life.
Slicing grinding wheel cutting method, flame cutting method. The main factors affecting the accuracy of the mold are: 1 product parts.
The quality requirements of 2 1 forgings include four aspects: the quality accuracy of raw materials, the level of die processing technology and means, and die assembly.
Quantity status and material preparation; Whether the selection of forging hammer tonnage matches the technical level of fitter 4. Production mode and mold manufacturing mode
Reason; The heating and cooling temperature of forging blank and the management level of each forging.
Whether the process parameters such as deformation are correct; Selection of forging method. The production cycle of mould begins with accepting the order task of mould.
Select the forging ratio. From the beginning of mold trial appraisal to the delivery of qualified molds
Mechanical copying is divided into different periods according to the installation position of the template.
The main factors that affect the mold production cycle are: 1 mold.
Standardization of replication technology and production 2 specialization of mold enterprises
Punching punch: first make the female die, and then preprocess the forming degree of the male die. 3. Modernization of mold production technology. 4.
Roughing each surface of the blank on the vertical milling machine according to the marking, so as to obtain the production management and management level.
The forming surface of the punch is fully lubricated. The main factors of punch production cost are: 1 1 die structure.
Pressing into the die mouth of the hardening concave die has the advantages of residual gold complexity and die performance, and high die precision.
Extrusion through the die mouth, and then the excess metal extruded is reduced to 3. Selection of mould materials. Mould processing equipment. Go to hell.
File it. Standardization and specialization of enterprise production.
24-hole series: female die, male die fixing plate, upper and lower die seats, etc. Constant 12 mold life: refers to the guarantee of mold to the quality of product parts.
With a series of round holes, the size of each round hole and the total number of parts that can be processed under their premise include
