Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 to 3, the internal contracting brake mechanism of the clapper die spotting press comprises a bumper 1; the fixing seat 2 is sleeved on the bumper 1, and a first inclined plane 3 is formed on the inner wall of the fixing seat 2; the locking ring is formed by enclosing a plurality of locking blocks 4, is movably arranged in the fixed seat 2 and movably abutted against the outer wall of the bumper bar 1, each locking block 4 is provided with a second inclined surface 5, the second inclined surfaces 5 are slidably abutted against the first inclined surfaces 3, and a locking gap 6 is formed between every two locking blocks 4; when the fixed seat 2 moves downwards, the locking block 4 can be driven to abut against the bumper bar 1.

The fixed seat 2 is arranged on the upper seat of the die spotting machine, the fixed seat 2 is sleeved on the bumper 1, the bumper 1 is used for bearing heavy objects, a locking ring formed by enclosing a plurality of locking blocks 4 is arranged in the fixed seat 2, a locking gap 6 is formed between every two locking blocks 4, when the locking gap 6 is reduced, the diameter of the locking ring is correspondingly reduced, namely, the cohesive force between the locking ring and the bumper 1 is increased, when the bumper 2 bears the weight of the template, the bumper is driven to move downwards, the friction force between the bumper 1 and the locking block 4 drives the locking block 4 to move downwards, the first inclined surface 3 of the fixed seat 2 slides relative to the second inclined surface 5 of the locking block 4, and further the locking gap 6 is reduced, so as to hold the bumper 1 tightly, and further fix the template at a certain position and keep the template still, and the structure of the band-type brake is simpler and more firm.

All seted up sliding tray 7 on every latch segment 4, be provided with the sliding block 8 that corresponds with 4 quantity of latch segment in the fixing base 2, sliding block 8 slides and sets up in sliding tray 7, and first inclined plane 3 sets up on sliding block 8, and second inclined plane 5 sets up in sliding tray 7.

The sliding block 8 and the sliding groove 7 are mutually limited, and the locking block 4 is ensured not to incline but move inwards.

The locking block 4 is provided with a limiting hole 9, a limiting pin 17 is inserted into the limiting hole 9, the sliding block 8 is provided with a U-shaped groove 16, the limiting pin 17 extends into the U-shaped groove 16, and the fixed seat 2 is detachably provided with the proximity switch 10 in an inserted mode.

When the locking block 4 moves upwards or downwards, the limiting pin 17 can be close to or far away from the proximity switch 10, so that whether the locking block is in a contracting brake or in a release state is judged.

Set up detachable on the fixing base and be provided with mount pad 11, seted up mounting hole 12 on the mount pad 11, proximity switch 10 activity runs through mounting hole 12.

The proximity switch 10 movably penetrates through the mounting hole 12, and the proximity switch 10 can be taken out or inserted according to the requirement to achieve the purpose of contracting a brake or moving.

Every 4 tip of latch segment all are provided with pretension spring 13, and every pretension spring 13 all is connected with fixing base 2.

Before the band-type brake is needed, the pre-tightening spring 13 gives the locking block 4 a downward elastic force, so that the locking block 4 moves relative to the fixed seat 2, the function of the pre-band-type brake is realized, and the safety is further improved.

The upper end of the fixed seat 2 is provided with a cylinder barrel 15, a piston ring 14 is movably arranged in the cylinder barrel 15, the lower end of the piston ring 14 abuts against the upper end of the locking ring, oil or air is supplied to the piston ring 14, the locking block 4 is pushed away by the piston ring 14, namely, the piston ring 14 can be driven to move downwards, the locking force of the locking ring can be reduced at the moment, the state of a band-type brake is relieved, the safety rod 12 can freely move upwards and downwards on the fixed seat 2, when oil or air is not supplied to the piston ring 14, the elastic force of the pre-tightening spring 13 enables the locking block 4 to move downwards to tighten the safety rod 1, and when a heavy object acts downwards, the locking force can be increasingly tightened.
