Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example (b):

as shown in fig. 1 to 4, a nail abutting seat head groove forming die comprises an upper template 11 and a lower template 12; the upper platen 11 is positioned above the lower platen 12. The upper die plate 11 is driven by an air cylinder. The upper template 11 is connected to the frame in a sliding mode, the lower template 12 is located in the frame, the air cylinder is fixed to the frame, and the air cylinder is located above the upper template 11. And a power shaft of the air cylinder is fixedly connected with the upper surface of the upper template 11.

A first pressing block 21 is fixed on one side of the upper template 11 facing the lower template 12, and the first pressing block 21 is used for abutting against the side wall of the nail abutting seat. The lower template 12 is provided with a holding groove 3 for holding the nail abutting seat, and the holding groove 3 is in a long strip shape.

In order to facilitate the location of the nail seat placed in the accommodating groove 3, a limiting mechanism 4 for locating the nail seat is arranged in the accommodating groove 3.

The limiting mechanism 4 includes a mounting hole 41, a slider 42, an elastic member 43, and a conductive inclined surface 44. The mounting hole 41 is opened on the side wall of the accommodating groove 3. The elastic member 43 is a spring, and is disposed in the mounting hole 41, and both ends of the elastic member are connected to the inner wall of the mounting hole 41 and the slider 42, respectively. The end of the slider 42 close to the elastic member 43 is rectangular and the end far away from the elastic member 43 is cylindrical.

The conductive slope 44 is opened at an end of the slider 42 away from the elastic member 43. The sliding block 42 is inserted into the positioning hole of the nail abutting seat.

When the nail abutting seat is erected laterally in the accommodating groove 3 and the side wall of the nail abutting seat abuts against the conduction inclined surface 44, pressure is applied to the sliding block 42, the sliding block 42 slides into the mounting hole 41, and the elastic piece 43 deforms and generates elastic force. When the positioning hole on the nail abutting seat corresponds to the sliding block 42 as the nail abutting seat further moves, the sliding block 42 is embedded into the positioning hole through the elastic force. The nail abutting seat can be positioned.

In order to facilitate the taking out of the nail abutting seat from the accommodating groove 3, a sliding hole 5 communicated with the mounting hole 41 is formed in the lower template 12, a pull rod 51 is connected in the sliding hole 5 in a sliding manner, and the pull rod 51 is fixedly connected with the sliding block 42.

After the groove is formed on the side wall of the nail abutting seat, the upper template 11 moves away from the lower template 12, and a pulling force is applied to the pull rod 51, so that the slide block 42 moves out of the positioning hole. The nail-supporting seat can be smoothly drawn out from the containing groove 3.

A sliding groove is formed in the bottom wall of the accommodating groove 3, and a second pressing block 22 slides in the sliding groove; the first pressing piece 21 corresponds to the second pressing piece 22. And a driving rod 6 is fixed on one side of the upper template 11 facing the lower template 12, and the driving rod 6 moves along with the upper template 11 towards the direction close to the lower template 12 and drives the second pressing block 22 to extend out of the sliding chute and be placed in the accommodating groove 3 through the conduction mechanism 7.

The transmission mechanism 7 includes a gear 71, a slide rod 72, a first inclined surface 73 and a second inclined surface 74. The gear 71 is rotatably connected to the lower template 12 and is used for being meshed with the sliding rod 72 and the driving rod 6. A connecting slot is provided in the lower die plate 12 in which the slide 72 is slidably connected. A first inclined plane 73 is arranged at one end of the sliding rod 72 far away from the gear 71; the second inclined surface 74 is provided at the lower end of the second press block 22 and is used for abutting against the first inclined surface 73.

The nail abutting seat is arranged in the accommodating groove 3 and is positioned through the limiting mechanism 4. The cylinder is actuated to move the upper die plate 11 downward, and the driving rod 6 abuts against the gear 71 and engages with the gear 71 to rotate the gear 71. Then, the gear 71 drives the sliding rod 72 to move, so that the sliding rod 72 moves toward the second pressing block 22. The second press piece 22 is guided out of the slide groove and placed in the accommodating groove 3 by the conduction action of the first inclined surface 73 and the second inclined surface 74. So that the first pressing block 21 and the second pressing block 22 act together to form a groove on the side wall of the nail abutting seat.

The lower die plate 12 is fixed with a stop (not shown in the figure) which is positioned at the opening of the connecting groove. The slide rod 72 is fixed with a limiting block 8 which is used for abutting against the limiting block 8.

After the groove is formed in the side wall of the nail abutting seat, the upper die plate 11 moves upwards, the driving rod 6 drives the gear 71 to rotate, after the driving rod 6 is separated from the gear 71, the sliding rod 72 continues to move along with the rotation of the gear 71 under the action of inertia until the limiting block 8 is abutted to the stop block, and the positioning of the sliding rod 72 is realized.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
