A kind of soft state billet cutting method and its cutting device

Abstract

The invention discloses a soft blank cutting method and a soft blank cutting device. The method comprises the following steps: a linear steel wire cutter moves to realize soft blank cutting; in a movable cutting process of the steel wire cutter, an inclined angle being more than zero is formed between the steel wire cutter and the horizontal plane; the steel wire cutter moves along the tension direction of the steel wire cutter when doing vertical undercutting movement; after the steel wire cutter finishes cutting, the steel wire cutter does resetting movement on a vertical undercutting face by bypassing a soft blank; the cutting device comprises a steel wire cutter driving device and a steel wire constant tension device, wherein the steel wire cutter driving device is composed of a chain wheel ring and a dynamic tracking and guiding device. According to the soft blank cutting method and the soft blank cutting device, the cutting process of the deformable linear steel wire cutter can be controlled by coordinating cutting movement and matching equipment, so that the one-way effective cutting of reciprocated cutting movement in a continuous conveying process of a strip-shaped blank is realized and the cutting requirements that the deformation of a cut section of an extruded and molded soft mud blank is small are met; the effective service life of a steel wire type cutter without blades is prolonged.

Description

technical field [0001] The invention belongs to the technical field of mechanical design and manufacture, in particular to the technical field of design and manufacture of a cutting machine, in particular to a method for cutting a soft blank and a cutting device thereof. Background technique [0002] Soft blanks refer to undried and solidified soft materials made through mixing, mud kneading and other steps, such as ceramics and some building materials. Usually, modeling and cutting are required when processing and shaping the above materials. [0003] The cutting process after extrusion molding of the honeycomb catalyst monomer is an important step in the catalyst production process. The extruded soft clay billet has a honeycomb cross section, the walls are very weak and the texture is particularly soft, and the shape of the cut section is extremely difficult to control. On the one hand, it is required that the deformation of the incision section is small, so that there is...

Problems solved by technology

This makes the life of the steel wire cutter a big problem: dozens to dozens of broken wires per hour are not applicable to the continuous production form of continuous extrusion molding, which greatly affects production efficiency

[0005] At the same time, the existing steel wire knife cutting method and its device cannot meet the requirements of the catalyst for the cross-section incision, and cannot guarantee to minimize the deformation of the incision and the microscopic tearing phenomenon of the incision section.
