Abstract
A bar loader for feeding a bar to a bar machining apparatus comprises a feeding rod for moving the bar and a guide rail for guiding the bar. The guide rail includes a guide rail body with an upper opening for receiving the bar and a lid member for covering the upper opening of the guide rail body and is operable to be opened and closed. A bar passageway formed between the guide rail body and the lid member has an inner wall surface. A plurality of oil grooves are formed on the inner wall surface which extend in a circumferential direction and arranged at a distance from each other in a longitudinal direction of the guide rail. It also has oil supplying system for supplying oil into the bar passageway.
Claims6
A bar loader constructed and arranged to feed a bar to a bar machining apparatus, comprising:
- a feeding rod which moves said bar;
- a guide rail constructed and arranged to guide said bar, said guide rail including a guide rail body with an upper opening for receiving said bar and a lid member for covering said upper opening of said guide rail body and is operable to be opened and closed, a bar passageway formed between said guide rail body and said lid member which accommodates substantially an entire bar and having an inner wall surface;
- a series of annular oil grooves formed on said inner wall surface and arranged at a distance from each other in a longitudinal direction of the guide rail;
- and
- an oil supplying system constructed and arranged to supply oil into said bar passageway at an axially intermediate location thereof.
A bar loader constructed and arranged to feed a bar to a bar machining apparatus, comprising:
- a feeding rod constructed and arranged to move said bar;
- a guide rail constructed and arranged to guide said bar, said guide rail including a guide rail body with an upper opening constructed and arranged to receive said bar and a lid member constructed and arranged to cover said upper opening of said guide rail body, said lid member operable to be opened and closed, a bar passageway formed between said guide rail body and said lid member constructed and arranged to accommodate substantially an entire bar and having an inner wall surface;
- a series of annular oil grooves formed on said inner wall surface and arranged at a distance from each other in a longitudinal direction of the guide rail;
- and
- an oil supplying system constructed and arranged to supply oil into said bar passageway at an axially intermediate location thereof,
- wherein said oil supplying system has an oil pump which supplies oil, and a thermal sensor mounted on said oil pump, and further comprising an alarm and an alarm controller which actuates said alarm when said alarm controller determines that the temperature of said oil pump has risen above a predetermined temperature level based on a signal transmitted from said thermal sensor.
