4. The U-bolt manufacturing system of claim 1, wherein: the top end of the upper die (1) is provided with a round fixing plate.

The technical field is as follows:

the invention relates to a U-shaped bolt manufacturing system.

Background art:

when the existing U-shaped bolt forming die is used for manufacturing the U-shaped bolt, the U-shaped bolt can fall on the lower die after being formed, and certain potential safety hazards can exist when the upper die is a force application die and is lifted by hands to take the bolt falling on the lower die, so that the existing U-shaped bolt forming die is necessary to improve the prior art so as to solve the defects of the prior art.

The invention content is as follows:

the present invention is directed to solving the above-mentioned problems of the prior art and to providing a U-bolt manufacturing system.

The technical scheme adopted by the invention is as follows: the utility model provides a U-shaped bolt manufacturing system, includes mould, bed die, gyro wheel, stripper, spring and guide arm, be equipped with the U-shaped groove on the bed die, all rotate on the both sides top in the U-shaped groove and connect a gyro wheel, go up the mould activity and peg graft at the U-shaped inslot, rotate in the bottom of last mould and connect a gyro wheel, the both sides of mould are placed in to two stripper symmetries, and the stripper is located the top of gyro wheel in the mould, two fixed guide arms on every stripper, the guide arm is pegged graft on last mould, the spring housing is located on the guide arm, and the one end of spring is contradicted on the stripper, the other end is contradicted on last mould.

Furthermore, the upper die comprises side plates and mounting ribs, the two side plates are arranged in parallel, the two mounting ribs are fixed on the two side plates, and two guide rods are inserted into each mounting rib.

Furthermore, the outer circumferential wall of the roller is provided with a groove.

Furthermore, a round fixing plate is arranged at the top end of the upper die.

The invention has the following beneficial effects:

when the bolt forming machine is used, the formed bolt is separated along with the upper die applying force, the bolt on the upper die is manually taken, potential safety hazards can be reduced, and the using effect is good.

Description of the drawings:

FIG. 1 is a block diagram of the present invention.

FIG. 2 is a block diagram of the present invention.

Fig. 3 is a partially enlarged view of the present invention.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, the U-shaped bolt manufacturing system of the present invention includes an upper die 1, a lower die 2, rollers 3, a stripper 4, a spring 5 and a guide rod 6, wherein the lower die 2 is provided with a U-shaped groove 21, the rollers 3 are rotatably connected to top ends of both sides of the U-shaped groove 21, the upper die 1 is movably inserted into the U-shaped groove 21, and the rollers 3 are rotatably connected to a bottom end of the upper die 1. Two stripper 4 symmetries are arranged in the both sides of last mould 1, and stripper 4 is located the top of roller 3 in the mould 1, fixes two guide arms 6 on every stripper 4, and guide arm 6 pegs graft on last mould 1, and on guide arm 6 was located to spring 5 cover, and the one end of spring 5 was contradicted on stripper 4, and the other end is contradicted on last mould 1.

The upper die 1 comprises side plates 11 and mounting ribs 12, wherein the two side plates 11 are arranged in parallel, the two mounting ribs 12 are fixed on the two side plates 11, and two guide rods 6 are inserted into each mounting rib 12.

The outer circumferential wall of the roller 3 is provided with a groove which can better facilitate bolt forming and has good limiting effect in the bolt forming process.

A round fixing plate is arranged at the top end of the upper die 1, and when the die is used, the round fixing plate is connected with a hydraulic cylinder.

During the use, arrange the bar material in on the gyro wheel 3 of bed die 2, then go up mould 1 and push down, press down the bar material into the U-shaped, behind the shaping for the U-shaped bolt, two sides of U-shaped bolt are contradicted on stripper 4 to spring 5 on stripper 4 inwards compresses. When the upper die is separated from the lower die, the discharging plate 4 can tightly abut against the side edge of the U-shaped bolt, the U-shaped bolt is separated from the lower die together with the upper die 1, and then the formed U-shaped bolt is left on the upper die and is convenient to take down.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
