Tension testing process of tensile testing machine on lock

Locks are tools that every household needs. Do you know that the production process of locks is very cumbersome? The following are the following questions for our company's technical staff.Tension testerInstructions in the testing and production of locks.

1. Flexibility

1.1 Flexible to enable

1.1.1 Definition

The key slides naturally, and the key rotates slowly along the lock core socket until the direction of the lock core slot is consistent, and can be inserted smoothly into the lock core slot; the lock core rotates flexibly, and the key should rotate without blockage within the working range, and the lock should be opened and closed freely; the key bounces back naturally, and after the lock is opened directly (open horizontally, after the bicycle lock is closed), the key will return to the key position by itself.

1.1.2 Test Methods

Hold the key in your hand and follow the lock core. Turn the key to insert it smoothly into the key slot of the lock core; turn the lock core with the key to be free of clamping; after the lock core rotates, the lock tongue, lock beam, and lock ring should jump out smoothly; when the lock is opened or closed, the key can be reset naturally and the key can be removed smoothly.

1.1.3 Testing Tools

Manual test or special equipment.

1.2 Key insertion and unplugging force

1.2.1 Definition

The force required when the key is inserted and pulled out of the lock cylinder slot.

1.2.2 Test Methods

Install the lock on the key insertion and removal force tester through the fixture, and correct the insertion and removal position of the key and lock core; then test and see the display value of the counter (repeat three times, and once is good as the standard).
