Impact of Punching Abrasive Tool on Service Life of Press

Punch mold can be divided into single mold works, compound mold, mold three kinds according to the authorities to continue. Need more of the first two people are not compatible with the economic function, always die can be the result of high accumulation. Communications, control and continue to die at high speed, and you produce the product (including all the products processed with a punch, Foxconn Group has terminals, computer cases and connectors used in hardware and the current mobile phone parts, etc.). Prepared for gradual death should pay attention to the polarization between the weight of the module, the precision of machining parts, accuracy, precision matching group to establish punch and participate in the topic, combined with mold production target.

Punch thinking mode to see:

Punch die in the structure can be divided into two cases: a limit (1). (2) common parts. Changes in the product. A total of part of the standards or norms, according to the gap between the finished product and the reform is normal.

The composition and the two. Template specification:

1 template composition

The composition of the press tooling will vary depending on the type and composition of the mold, the sequence, the type of traps, and the top-down physical layout. The former is the key to constructing the most frequently used, the latter structure or the extra deep drawing die.

The main work of this paper is:

(1) digital mapping – the three-dimensional products and mold models and two-dimensional engineering drawings, to change the traditional treatment;

(2) the digital bed model – the product of the mold and the product of the association hope to be born, the mold of the three – dimensional solid model;

Digital simulation (3) die – to clarify the product of the forming process analysis, terms, understand the structure of the mold parts of the thermal decomposition table, drowsiness hands and feet mold;

(4) product formation process imitation – injection molding, punch;

(5) custom sound company mold set its order and standard adjustment;

(6) mold production and processing.

Specification 2 of the mold

. The size of the mold and the locking screw

The template size should be larger than the taskbar and select a typical template size. The template locking screw shows the relationship between mold size and mold size. The most frequently manipulated tooling locking screws are based on the four corners of the case and can be used in geo-paradigm behavior. The long letter series of molds most frequently used locking screws in four corners to create and center the center of gravity.

(1). template

The overall correlation structure, the template thickness choice and the mold punch processing type, the punch cutting force, the punch processing precision and so on. According to the thickness of the mold to determine the appearance of the revelation is heavy, the experience gained and the strategy to use the appropriate template thickness usually, although not uniform, height and clamping height of the mold standard, simple procurement and inventory management.

Template four:

The main template for the continuous punching fixed plate, platen, the mother template, etc., according to precision machining, punch products, to convince the eel processing mold production, to provide assistance, if the following three mold repair steps: (2) 1) yoke, (2) insertion.

1 piece style

A block template is also known as a structure type, and air must be turned off for processing. The overall template for the purely structural or precision molds is mainly high, cutting the main template (3) processing methods to receive the thermal action must be wire-cut processing or EDM and grinding. The length of the template size is good (no heat treatment) will select two or more types and.

2 yoke type

Yoke-type template to remove the central groove-type block product assembly. With the operation of the volts under the construction, the groove is also composed of templates. The yoke template structure price: ditch easy processing, ditch processing precision width can transform, well and so on. But low rigidity optimization finds losses.
