Description

A kind of metal plate punching technique

Technical field

The invention belongs to processing technique field, specifically a kind of metal plate punching technique.

Background technology

Existing metal plate punching technological operation step is chaotic, or operating process is lack of standardization, and metal plate punching technique does not obtain good specification, thus is difficult to ensure that product quality, it is necessary to be further improved.

Summary of the invention

In view of the deficiency that prior art exists, it is an object of the invention to provide the metal plate punching technique of a kind of product, by each rule of operation of specification metal plate punching, it is possible to effectively ensure product quality.

The technical scheme realizing the object of the invention is as follows:

A kind of metal plate punching technique, it is characterised in that its Sheet Metal Forming Technology includes claimed below:

(1) technological requirement: check the security reliability of machinery, electric property；The part that need to process can should be processed after the assay was approved through last process；Wanting clear and definite technology requirement before processing, verification supplied materials has zero defect；Corresponding mould is selected according to processing request；First by slider of punch point to top dead-centre, upper module is loaded in slide block die shank groove, ajust and set level；Screw, jackscrew being screwed, must not there be gap upper module and slide block bottom surface；Bed surface erasing is clean, after removing greasy dirt iron filings, lower module is placed on press bolster；Crawl is driven or setting stick bull wheel, makes slide block to bottom dead centre thread into counterdie, adjusts connecting rod height；Ensure that peripheral clearance is consistent；Being compressed by lower module pressing plate, flatten, parallels and bed die dish to wait height, and fixing point wants symmetry；Locking connecting rod, checks that mould has non-loosening phenomenon；Carry out examination slug, check that whether section is neat, uniform, consistent；Adjust making sheet by dimensional requirement, reserve vertical reference and horizontal reference；Work in-process material to be close to making sheet, to set level on bed die；Punching, when smearing angle it is noted that machine direction, it is to avoid punching mistake；The part processed is answered sorting placement neat and labels；

(2) inspection requirements: strict implement initial workpiece checks, centre is spot-check, tailpiece check；Work pieces process size checks by drawing or technical papers；Should there be stretching, bending in punching edge, and burr height is not more than the thick 10%-15% of material；Pass must not twisted, deflection；

(3) safety requirements: material is not put before surely, foot is not placed on pedal, in order to avoid causing quality and industrial accident;Operator should be familiar with the equipment used, and answers energy to concentrate during operation；Check that mould has non-loosening phenomenon at any time, it has been found that problem adjusts in time；Trip bolt should be unclamped during adjustment, must not thump；As found to cause punching burr, stretching because of die wear, should repair a die immediately or more renew mould.

A kind of metal plate punching technique of the present invention, by each step requirement of specification, Parameter Conditions and points for attention, to guarantee product quality, improves the yields of product, it is possible to effectively improve ram efficiency, saves production cost and time.

Detailed description of the invention

Below in conjunction with embodiment, the invention will be further described, and its operating procedure is as follows:

A kind of metal plate punching technique, its Sheet Metal Forming Technology includes claimed below:

(1) technological requirement: check the security reliability of machinery, electric property；The part that need to process can should be processed after the assay was approved through last process；Wanting clear and definite technology requirement before processing, verification supplied materials has zero defect；Corresponding mould is selected according to processing request；First by slider of punch point to top dead-centre, upper module is loaded in slide block die shank groove, ajust and set level；Screw, jackscrew being screwed, must not there be gap upper module and slide block bottom surface；Bed surface erasing is clean, after removing greasy dirt iron filings, lower module is placed on press bolster；Crawl is driven or setting stick bull wheel, makes slide block to bottom dead centre thread into counterdie, adjusts connecting rod height；Ensure that peripheral clearance is consistent；Being compressed by lower module pressing plate, flatten, parallels and bed die dish to wait height, and fixing point wants symmetry；Locking connecting rod, checks that mould has non-loosening phenomenon；Carry out examination slug, check that whether section is neat, uniform, consistent；Adjust making sheet by dimensional requirement, reserve vertical reference and horizontal reference；Work in-process material to be close to making sheet, to set level on bed die；Punching, when smearing angle it is noted that machine direction, it is to avoid punching mistake；The part processed is answered sorting placement neat and labels；

(2) inspection requirements: strict implement initial workpiece checks, centre is spot-check, tailpiece check；Work pieces process size checks by drawing or technical papers；Should there be stretching, bending in punching edge, and burr height is not more than the thick 10%-15% of material；Pass must not twisted, deflection；

(3) safety requirements: material is not put before surely, foot is not placed on pedal, in order to avoid causing quality and industrial accident;Operator should be familiar with the equipment used, and answers energy to concentrate during operation；Check that mould has non-loosening phenomenon at any time, it has been found that problem adjusts in time；Trip bolt should be unclamped during adjustment, must not thump；As found to cause punching burr, stretching because of die wear, should repair a die immediately or more renew mould.

The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should at the protection domain being defined in the patent claims under this invention's idea on the basis of existing technology by logic minute analysis, reasoning or the available technical scheme of limited experiment.
