In a preferred aspect, each of the stations includes a cleaning station for cleaning the work, a coating station for applying a lubricant to the work cleaned at the cleaning station, and a lubricant applied at the coating station. A drying station for drying the work.

This lubricant coating apparatus has three stations for cleaning, coating and drying in which stations for processing a work are sequentially arranged.
It consists of two stations and can be applied when applying a one-part type lubricant.

Here, in the above-mentioned bond processing, since a long time is required for the film formation process, in order to improve the productivity, it is general to carry out batch production in which a certain number of products are collectively produced. is there. In the case of such lot production, the size of the processing apparatus increases in accordance with the number (lot size) produced in one lot.

In this regard, when a one-part type lubricant is used, the coating time in the coating station requires a longer time than the cleaning time and the drying time, but the coating time itself is about 30 seconds. Processing time (about 240 seconds)
Extremely short compared to. For this reason, even when processing a single item (or about several pieces) of workpieces without performing lot production,
The productivity can be sufficiently improved as compared with the bond processing. Therefore, when a one-component type lubricant is used, it is more advantageous in improving the productivity while suppressing an increase in the size of the apparatus, as compared with the bond processing in which lot production is indispensable for improving the productivity.

You. The elevating motor 94 is controlled so as to move up and down by a predetermined distance in order to reciprocate the work holding arm 7 and the like between the uppermost position, which is the transfer position, and the lowermost position, which is the processing position.

The processing time in each station is determined by setting the time. In this embodiment, the processing time is set in accordance with the processing time in the coating station 2. That is, the water-based lubricant, which is a one-component type lubricant, is applied to the work W
Since the processing time required to apply the coating W is about 30 seconds, the time required for the work W to be immersed in the lubrication tank 2a of the coating station 2 is 30 seconds in order to secure the processing time of 30 seconds in the coating station 2. In this way, the time from the lowering of the processing position to the lowest position to the rising of the transport position to the highest position is set to 30 seconds.

The manner of applying a one-part type lubricant to the surface of a work W for cold forging using the lubricant applying apparatus of the present embodiment having the above configuration will be described below.

First, with the work holding arm 7 and the like lowered to the lowest position, which is the processing position, the work holding arm 7 is placed on the work holding table 73 of the work holding arm 7 at the work setting position at the right position a in FIG. The work W is set manually.

Thus, the work W held on the work holding table 73 can be sequentially conveyed to each station to perform processing at each station.

In the washing station 1, the work W is first washed at a lower right position b in FIG. 1 by immersing the work W in a washing tank 1a for 30 seconds, and then at a lower position c in FIG. W is drained for 30 seconds.

In the lubrication station 2, the work W is immersed in the lubrication tank 2a for 30 seconds at the lower left position d in FIG. 1 to apply a one-liquid type water-based lubricant to the surface of the work W. .

The W is dried, and then is set to an idle state where no processing is performed for 30 seconds at the upper position g in FIG.

The workpiece W, which has been processed at each station, is transported from the upper position g in FIG. 1 to the upper right position h, and is lowered from the transport position to the processing position by the operation of the elevation driving means 9.
