Abstract

A wire shaving apparatus for shaving a periphery of wire, bar or rod stock, including structure defining a product flow path between an input and an output and a plurality of shaving stations spaced along said flow path for scrapingly engaging product conveyed through said structure. Each shaving station includes a pair of slide mechanisms, one slide mounting a releasable tool cartridge including a pair of cutting tools having associated cutting edges positioned at a predetermined angle, and another slide assembly mounting a product support cartridge including support rollers aligned with said cutting tools for supporting said product as it is being scraped. The slides are reciprocally moved between processing and retracted positions by a threaded drive shaft, the rotation of which is controlled by a servo controlled system. A clamping arrangement associated with each slide mechanism releasably clamps the tool and support cartridges allowing easy and speedy replacement. A guide assembly guides the product as it leaves the structure and includes a fluid pressure operated actuator for driving a pair of pinch rollers towards and away from the product flow path whereby a variety of rod stock diameters are accommodated.

Claims27

Dependent claims

A wire shaving system for continuously processing bar stock, comprising:

(a) structure having an input for receiving bar stock to be processed and an output for discharging processed bar stock, said structure defining a processing path between said input and said output;
(b) a plurality of shaving stations spaced along said processing path, each station operative to shave a portion of the peripheral surface of said bar stock;
(c) each station including:
(i) a pair of slide mechanisms mounted for movement towards and away from each other;
(ii) drive means associated with each of said slide mechanisms, each drive means operable to reciprocally move said associated slide mechanism between a retracted and a plurality of extended positions;
(iii) control means for controlling each of said drive means to provide coordinated movement between said slides such that a predetermined spacing between said slides can be selected;
(iv) one of said slides mounting at least one cutting blade, said cutting blade operative to scrapingly engage a surface portion of said bar stock when said one slide is in a scraping portion;
(v) said other slide mounting a backup means for supporting said bar stock as it travels past said cutting blade;
(d) said drive and control means operable to retract said slide mechanisms to a position at which said cutting blade and said backup means disengage said bar stock and further operable to concurrently extend said slide mechanisms to a selected spaced position at which said cutting blade and said backup means currently engage said bar stock.

A shaving machine comprising:

(a) structure defining a rigid frame including a plurality of vertical standing plates each mounting a shaving apparatus;
(b) said structure defining an input end and an output end;
(c) a guide means mounted at said output end for supporting product exiting said structure;
(d) said cutting stations defining a product flow path aligned with said input and output ends of said structure;
(e) each cutting station comprising:
(i) a cutting tool assembly movable towards and away from said product flow path and a product support assembly movable towards and away from said product flow path;
(ii) drive means including associated drive motors for actuating said tool and product support assemblies including sensing means for monitoring and establishing a maximum retracted position and a miximum extended position for each assembly;
(iii) control means for controlling each drive means, said control means operative to coordinate the actuation of said assemblies such that a predetermined spacing between said tool assembly and said product support assembly can be automatically selected, said control means and drive means further operable to drive said assemblies concurrently such that a product to be scraped is substantially concurrently engaged by said tool and support assemblies as said assemblies arrive at their selected spacing;
(iv) means releasably mounting a cutting tool to said tool assembly;
(d) means for conveying said product along said product flow path.
