Problems solved by technology

[0002] The trimming machine is a device that cuts the head of the bolt blank made by the cold heading machine into a hexagonal head shape. Compared with the traditional cutting die, it saves expensive mold opening costs, die cutting costs and die cutting time. , so that the processing of the sample is extremely simple and convenient, the flexibility is good, and the quality of the processed sample is high, but the surface quality of the large-sized bolts processed by the existing trimming machine is poor, the dimensional accuracy is low, and the processing The hexagonal head part of the finished bolt is uneven and has many burrs, which seriously affects the quality of the processed bolt, and the debris generated by processing is easy to accumulate on the conveying track, affecting the normal operation of the equipment

Embodiment 1

[0014] The present invention includes a machine platform 1, an installation top plate 2, a waste trough 3, a clamping mechanism 4, a transmission track 5, a trimming track 6, a trimming screw 7, a trimming knife 8, a motor 9, a lifting shaft 10, and a rotating shaft 11 , angle grinding disc 12, compressed oil and gas tank 13, A oil and gas channel 14, B oil and gas channel 15, the upper end of the machine table 1 is provided with an installation top plate 2, and the inside of the installation top plate 2 is provided with A oil and gas channel 14, and the inside of the rotating shaft 11 is provided with There is B oil and gas passage 15, and there is a waste material chute 3 inside the machine 1. When installing, first install the clamping mechanism 4 inside the waste material chute 3, and install the conveying track 5 and the trimming track 6 on the machine 1 perpendicular to each other. , the edge trimming knife 8 is installed on the edge trimming track 6 through the edge trim...

Embodiment 2

[0016] When in use, the bolt blank is transferred to the clamping mechanism 4 through the transmission track 5. After being clamped by the clamping mechanism 4, the two trimming screw screws 7 located on both sides of the clamping mechanism 4 are synchronously fed to the bolt through the trimming track 6. The blank moves, and at the same time controls the movement of the edge trimming knife 8. When the edge trimming knife 8 moves to the processing position, the bolt blank is trimmed, and then the edge trimming knife 8 returns to the initial position, and the rotating clamping mechanism 4 clamps the bolt blank. Rotate to a new processing angle, repeat the edge trimming according to the above edge trimming method, until all six sides are trimmed, the edge trimming knife 8 returns, and the lifting shaft 10 drives the angle grinding disc 12 to descend. A oil-gas channel 14 and B oil-gas channel 15 are instantly connected, so that the compressed oil-gas in the compressed oil-gas tan...

Abstract

The invention provides a novel bolt edge cutting machine. The novel bolt edge cutting machine comprises a machine stand, an installation top plate, a waste trough, a clamping mechanism and the like. The installation top plate is arranged at the upper end of the machine stand. The waste trough is formed in the machine stand. The clamping mechanism is arranged in the waste trough. A conveying rail and an edge cutting rail are installed on the machine stand. Edge cutting knives are installed on the edge cutting rail through edge cutting lead screws. A motor and a compressed oil gas tank are arranged on the installation top plate. An oil gas channel A is formed in the installation top plate, and the oil gas channel A is connected with the compressed oil gas tank. A rotary shaft is installed at the lower end of the motor through a lifting shaft. An oil gas channel B is formed in the rotary shaft. An angle lapping disc is arranged at the lower end of the rotary shaft. According to the novel bolt edge cutting machine, symmetrical edge cutting is conducted on a bolt blank three times through the two edge cutting knives, and the machining precision is improved; and angle lapping is conducted on the hexagon head of a bolt through the angle lapping disc, and thus the quality of the bolt is improved.
