Electricity cabinet locks punch fracture chipping

(1) Cause:

a jump crumbs, crumbs material blocking, card die as a result of;

b, improper feeding material cut in half;

c, the insufficient strength of the punch;

d, the size of the punch too close to punching material traction, causing small punch off;

e, electrical cabinet locks local punch and die too sharp corners;

f, blanking clearance is too small;

g, no of stamping oil or use stamping oil volatile;

h, uneven blanking clearance, offset, convex and concave mold interfere;

i, unloading inserts poor accuracy or worn to lose precision-oriented features;

j, mold-oriented are not allowed to wear;

k, convex and concave mold improper material selection, improper hardness;

i, on materials and parts (sales) wear; the m, gaskets additional improper.

(2) responses:

a, solve hop cuttings, scrap material blocking the card mode; pay attention to feeding, timely pruning strip, clean up the mold in a timely manner;

c, to modify the design, add punch overall strength, less short the die straight blade size, pay attention to the the punch blade surface repair a slope or curved, cut into small part;

d, the length of the small punch wear short relatively large convex mold one more than the thickness of the material;

e, modify the design;

f control punch and die machining accuracy or modify the design gap, appropriate to increase the small portion punching gap;

g, adjust the the stamping oil droplets oil or replace the oil types;

h, check each forming parts accuracy, and subjected to adjustment or replacement, control of the machining accuracy;

i, training or replacement;

j, electricity cabinet locks replacement guide post, guide sleeve, pay attention to routine maintenance;

k, replace the use of materials, the use of appropriate hardness;

i Only change the materials and parts;

m, correction, gaskets, rest less, and the use of steel pad die pad in pad below the pad.

Electricity cabinet locks bronze tripod bending deformation of dimensional variation

(1) Cause:

a guide pin to wear the pin diameter;

b, bending lead-bit part of the precision differential wear;

Bend the tabs, die wear (pressure loss);

d, less than the demise of the mold;

e, material slip Bend the tabs, die no guide-bit function, not bending to impose preload;

f, mold structure and poor design size;

g, electricity cabinet locks stamping burrs, poor triggered bent;

h, bending parts of the punch die additional spacer more size instability;

i, material thickness dimension of the variation;

j, the material mechanical-shaped variation.

(2) responses:

a replacement guide pin;

b reground or replaced;

c reground or replaced;

d, checking, correction;

e design modifications and additional lead-bit and pre-press functions;

f, modify the design size, decomposition bending, increase the bending and shaping;

g, training cutting bit incision;

h, electricity cabinet locks adjustment, the overall steel pad;

i, replacement materials, to control the quality of the feed;

j, replacement materials, to control the quality of the feed.

The cabinet locks stamping the level of (a mold pieces)

(1) Cause:

a stamping burrs;

b, stamping crushed crumbs material in the mold;

c, convex, concave mold (bending-bit) pressure loss or damage;

d, punching stacker;

e, binder parts wear, pressure loss;

f, tear cleavages tear cut to match the size of knife-edge wear;

g, easily broken bit pre-cut depth inconsistent, punch and die wear or chipping;

h, hit the convex parts of the punch and die chipping or wear more serious;

i, mold design flaws.

(2) responses:

a training cutting bit incision;

b, electricity cabinet locks clean up the mold, to solve the problem of material floating debris;

c, re-training or replaced with new parts;

d, training punching incision? bald? Kau chisel the doorpost Ken structure delta broom basket for fruits, inspection, implementation, maintenance or replacement;

f, repair or replacement guarantee tear cut situation;

g, check the pre-cut convex, concave die situation, the implementation of maintenance or replacement;

h, checking the convex and concave mold position, the implementation of maintenance or replacement;

i, design modifications, additional height adjustment or additional shaping station.
