Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, in particular to a cold heading machine for processing automobile blanks. Background Art

[0002] Cold heading machine is a forging machine that thickens the top of bars or wires at room temperature. It is a special equipment mainly used for mass production of nuts, bolts and other fasteners. Cold heading machine uses cold heading method to forge the heads of bolts and screws, which can minimize cutting work and directly form them into the required shape and size, which can not only save a lot of materials, but also greatly improve production efficiency and significantly improve the mechanical strength of the forged parts.

[0003] When cold heading machines are used to form fasteners and steel balls, the bars need to be cut into cylinders of uniform length. The bars need to be oiled during cutting and feeding. The oiling method can reduce the friction between the bars and the cutting mechanism. At the same time, the friction with the die is also reduced during subsequent processing. The existing oiling method is usually to fix an oil-soaked brush on one side to brush the oil on the bars. This oiling method makes the oil distribution on the bars uneven. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5The utility model discloses a cold heading machine for processing automobile blank parts, including an installation shell plate body 1, the installation shell plate body 1 has two vertical plates 2, and a lower guide roller 3 and an upper guide roller 4 arranged up and down are rotatably connected between the two vertical plates 2. A collecting box 5 for storing oil inside is installed on one side of the upper guide roller 4 between the two vertical plates 2. The inner cavity of the collecting box 5 is rotatably connected with a lower oil brush roller 6 whose top protrudes to the outside of the collecting box 5. An oil storage box 7 is also arranged between the two vertical plates 2. A mounting groove 8 is formed at the bottom end of the oil storage box 7, and an upper oil brush roller 9 cooperating with the lower oil brush roller 6 is rotatably connected in the mounting groove 8. Annular oiling grooves are provided on the upper and lower oil brush rollers 9 and 6. The cold heading machine for processing automobile blank parts can evenly oil the bar material for processing through the cooperation of the upper and lower oil brush rollers 6. The cooperation of the collecting box 5 and the inclined plate 13 is convenient for collecting the oil dripping downward from the oil storage box 7.

[0020] Specifically, the inner cavity of the collecting box 5 forms a storage cavity 10 for storing oil, and the bottom end of the storage cavity 10 is provided with an oil dripping pipe with a valve installed.

[0021] In this embodiment, the valve on the oil dripping pipe can be a butterfly valve, a ball valve or the like, which can allow the oil in the storage chamber 10 to drip downward along the oil dripping pipe to the upper oil brush roller 9, so that the upper oil brush roller 9 has oil, and the rod material passing through the oiling groove can be oiled.

[0022] Specifically, a connecting plate 12 is fixedly connected to one side of the bottom end of the collecting box 5 . A through slot 14 is formed on the connecting plate 12 . The bottom end of the connecting plate 12 is connected to the collecting box 5 via an inclined plate 13 .

[0023] In this embodiment, the rod material can pass through the oiling grooves of the upper oil brush roller 9 and the lower oil brush roller 6, and can pass through the through groove 14. The oil dripping downward from the upper oil brush roller 9 can drip onto the inclined plate 13, and can flow downward along the inclined plate 13 to the inner cavity of the collection box 5.

[0024] Specifically, blocking bars 15 are fixedly connected to both sides of the inclined plate 13 .

[0025] In this embodiment, the provision of the blocking bar 15 can prevent the oil from sliding down along the inclined plate 13 from being blocked and prevent the oil from sliding down from the side of the inclined plate 13 .

[0026] Specifically, an annular groove 11 is formed on the lower guide roller 3 and the upper guide roller 4 .

[0027] In this embodiment, the top of the groove 11 on the lower guide roller 3 is at the same height as the top of the oiling groove on the lower oil brush roller 6. The setting of the groove 11 can prevent the bar from running off course.

[0028] Specifically, the lower guide roller 3 is driven by a grooved wheel mechanism.

[0029] In this embodiment, the groove wheel mechanism is common knowledge in the field, which can make the lower guide roller 3 move intermittently to intermittently convey the rod material. Its working principle is a well-known technology and its working method will not be explained in detail in this scheme.

[0030] In summary, the cold heading machine for processing automobile blanks can evenly oil the rods for processing through the cooperation of the upper oil brush roller 9 and the lower oil brush roller 6, and the cooperation of the collecting box 5 and the inclined plate 13 facilitates the collection of oil dripping downward from the oil storage box 7.
