What are the requirements for the operation rules and regulations of the metal stamping process workshop?

Stamping process is a method of applying external force to the blank through the die to make it plastically deform or separate, so as to obtain a workpiece with a certain size, shape and performance. As people's demand for metal products enters a diversified era, new requirements are put forward for stamping technology. According to the actual situation of equipment and personnel, the stamping and drawing process should select and design an advanced, economical and reasonable process scheme with safe and reliable use. The operator's operation level affects the quality of the workpiece to a certain extent, and the irregular operation has great security risks, so it is particularly important to standardize the operation of personnel through strict rules and regulations. Here is a brief introduction to the rules and regulations of the stamping process workshop:

First, the preparation before punching.

(1) Check whether there are irrelevant workpieces and sundries in the stamping area before going to work. After cleaning, check whether the upper and lower dies and screws are loose. If the mold is loose, it must be reassembled.

(2) Read the handover record carefully to understand the operation and existing problems of the last machine tool;

(3) It is necessary to check whether the lubrication system and mechanical system of the machine tool are normal. Use the self-contained oil pump to add lubricating oil once to prevent dry grinding of crankshaft copper sleeve and sleeve rail.

(4) Check whether the console, guide rail and main sliding surface have new pulling, grinding and bumping, and if so, notify the team leader or equipment member to check together and make records;

Second, the matters needing attention when installing the mold

(1) The contact points of the upper and lower molds must be wiped clean, and the guide shaft sleeve of the mold is not allowed to expose the guide shaft rod.

(2) The upper and lower dies must be parallel, the upper punch and the lower die surface must be vertical, and the die pressing plate should be flat.

(3) The impact center of the punching die must coincide with the pressure center of the punching machine, and the maximum impact force shall not exceed the rated pressure of the machine.

(4) Don't put the screws and other items under the mold and tray by hand, so as not to crush your hands.

(5) When loading and unloading molds, lubricating machine tools and troubleshooting, the power supply must be cut off until the flywheel stops rotating.

Three. Check after starting the punch.

(1) Check whether the clutch and brake are flexible and easy to use, and whether the pedals, tie rods, templates, screws and various transmission devices are loose.

(2) When abnormal problems are found, the main power supply must be turned off before troubleshooting or maintenance.

(3) When the mold is closed, it should be stopped when the flywheel stops running. When closing the mold, manually check the stamping stroke once or twice and start the machine after it is confirmed.

(4) Check whether the punch can move freely on the guide rail, whether the flywheel jumps and whether the flywheel clutch is reliable.

(5) It is necessary to check whether the protective cover, the die and the pressure plate are installed firmly, and whether the punch machine has repeated combo phenomenon.

(6) It is necessary to check whether the ejector is operated accurately and whether the blank is suitable for stamping.

Four, the operation matters in the process of stamping

(1) It is forbidden to put hands and heads between punches, dies and backing plates.

(2) It is forbidden to correct the position of the die blank during the operation of the slider and after stepping on the pedal or operating handle.

(3) It is forbidden to let He Dongxi change the pedal mechanism or pad anything on the punch table.

(4) It is forbidden to put multiple blanks on the mold at the same time and clean up the iron filings and wastes by hand.

(5) When it is found that there is abnormal sound between the impact of the punch and the automatic falling, and the operating mechanism and the automatic stop mechanism are not working normally, the operation is prohibited.

(7) It is forbidden to overlap and forcibly punch two or more workpieces, and only one workpiece is allowed to be punched at a time, so as to avoid damaging equipment, molds and personal accidents.

Verb (abbreviation for verb) cleaning operation after operation is completed.

(1) Turn the mechanical, hydraulic and pneumatic operating handles, cutting doors and switches to non-open positions;

(2) Stop the operation of the punching machine and cut off the power supply, gas supply and other supply equipment;

(3) Clean the operation site and carefully wipe the machine tool. Refueling and maintenance of guide rail surface, rotating sliding surface, positioning datum plane, operation desk, etc.

(4) Carefully fill the machine tool problems found in the class into the handover record book, and do a good job of handover.
