Description

Novel cold heading device for hexagonal fastener

Technical Field

The utility model relates to a novel hexagonal fastener's cold-heading device.

Background

The cold header is a special device which takes a pier as a main part and is specially used for producing fasteners such as screws, nuts, bolts and the like in batches, wherein the hexagonal fastener is used for installing automotive interior parts, and the demand is very large.

In the working process of the traditional cold heading device, lubricating oil needs to be added to an upsetting mechanism manually, the manual lubricating oil adding is time-consuming and labor-consuming, and is occasionally forgotten, so that the machine is unsmooth in operation; lubricating oil is added to the upsetting mechanism by using equipment, but when the lubricating oil is added to the equipment, the oil filling pipe cannot reach the position needing lubricating at the lower end of the upsetting mechanism, so that the normal operation of the machine is influenced; in addition, after the lubricating oil is added into the machine, part of the lubricating oil drops and a small amount of lubricating oil permeates out of the machine, so that the lubricating oil is wasted. Therefore, a cold heading device of a novel hexagonal fastener, which can accurately lubricate an upsetting mechanism, does not influence the normal operation of the upsetting mechanism and can recycle lubricating oil, is urgently needed at present.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the aforesaid not enough, provide one kind and can accurately lubricate upsetting mechanism, and do not influence its normal operating, but lubricating oil recycle's novel hexagonal fastener's cold-heading device.

The purpose of the utility model is realized like this:

a cold upsetting device of a novel hexagonal fastener comprises an upsetting mechanism and a lubricating system, wherein the upsetting mechanism comprises an upper die and a lower die, and the lubricating system is arranged between the upper die and the lower die; the upper die is driven by an oil cylinder to do reciprocating linear stamping motion in the left-right direction, a stamping head is arranged on the right side of the upper die, a plurality of screw holes for placing hexagonal fasteners are formed in the left side of the lower die, and the hexagonal fasteners in the screw holes are stamped by the stamping head;

the lubricating system comprises an oil pipe, the oil pipe is arranged between the upper die and the lower die, two ends of the oil pipe are respectively hinged with the support column through bearings, and the oil pipe can rotate relative to the support column; be provided with a plurality of valves on the oil pipe, all be connected with the oil spout pipe towards the lower mould on a plurality of valves.

The utility model discloses hexagonal fastener's cold-heading device, the oil pipe below is provided with the sump oil tank, and the sump oil tank is gone into oil pipe with lubricating oil pump wherein.

The utility model discloses hexagonal fastener's cold-heading device has following advantage:

the utility model discloses set up in the cold-heading device of hexagonal fastener can be relative to the oil pipe of oil pipe support rotation, set up a plurality of valves on the oil pipe, the valve is connected and is spouted oil pipe, spouts oil pipe can rotate to the position that needs lubrication in the upsetting mechanism, sprays lubricating oil to it, spouts lubricating oil to required position more accurately, guarantees the normal operation of machine; the cold heading device of the novel hexagonal fastener of the utility model does not need manual lubrication oil adding, saves labor force and improves work efficiency; the utility model discloses set up the sump oil tank among hexagonal fastener's the cold-heading device, collected the lubricating oil that permeates out in the machine and again with going into oil pipe well cycle use, avoided the wasting of resources.

Drawings

Figure 1 is the utility model discloses hexagonal fastener's cold-heading device's schematic structure.

In the figure: the upsetting mechanism 1, the upper die 11, the stamping head 12, the lower die 13, the screw hole 14, the lubricating system 2, the oil pipe 21, the oil spraying pipe 22, the valve 23, the support column 24, the bearing 25 and the oil collecting tank 3.
