Abstract

The invention discloses a bar material blank processing device which comprises a cutter holder, a cutter holder seat, a linear ball guide rail, a ball screw, a column, an upper servo motor and a lower servo motor. The cutter holder and the cutter holder seat are used for fixing an external circle turning tool, the linear ball guide rail is fixed on the column, the ball screw is arranged in the longitudinal direction of the linear ball guide rail and parallel to the linear ball guide rail, the cutter holder seat is connected with a nut seat of the ball screw, the two sides of the cutter holder seat are arranged in slide grooves on the two sides of the linear ball guide rail, the upper end of the ball screw is connected with an output shaft of the upper servo motor through a coupling, the upper end of an upper thimble is connected a clamping and adjusting device which can adjust the vertical position of the upper thimble, the clamping and adjusting device is fixed on the column, and a lower thimble is connected with an output shaft of the lower servo motor to achieve rotation of bar material blanks. The rotation motion of the ball screw is converted into the linear motion of the nut seat to drive the cutter holder seat to slide along the linear ball guide rail, so that external circles of the bar material blanks can be longitudinally turned. By means of the bar material blank processing device, the problems that bar material blanks are inconvenient to clamp, prone to being broken in transmission and the like are solved. Furthermore, a pre-sintering link is removed.

Description

technical field

[0001] The invention relates to a processing device for a bar blank, in particular to a processing device for a hard alloy isostatic pressing bar blank. Background technique

[0002] The forming methods of cemented carbide rods mainly include: compression molding, extrusion molding, isostatic pressing, etc. Compression molding and extrusion molding are suitable for producing large quantities of small-sized rods, and the obtained products have high surface quality and dimensional accuracy. The isostatic pressing method is generally used to produce large-sized products, which have good compactness and uniform internal density, but the surface quality and dimensional accuracy of the products are poor.

[0003] The strength of the bar blank formed by isostatic pressing is not high (unsintered), and it is not suitable for external turning on a general-purpose lathe. General-purpose lathes mostly use pallets for horizontal processing of isostatic bar blanks. The ...
