Description

Technical Field

[0001] The utility model relates to the technical field of milling cutters, in particular to a rolling device for forming and processing hard alloy milling cutters. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. During operation, each tooth cuts off the excess of the workpiece intermittently in sequence. Rolling is an indispensable step in the milling process. The rolling process usually refers to the mechanical process of deformation of the rolled piece between the rollers. In order to analyze the relationship between the basic parameters in the rolling process, the so-called simple ideal rolling process is established, assuming that the rolled metal is a homogeneous and continuous rigid-plastic body with a rectangular cross-section. The rollers are a pair of flat rollers with equal diameters and speeds, without external tension or thrust, and the main parameters of the deformation zone are determined based on this.

[0003] After searching, in the prior art, the Chinese patent with patent application number CN 112705573 A discloses a rolling device for forming and processing carbide milling cutters, including a base and a left support and a right support, wherein the base is provided with a fixed platform 1 and a fixed platform 2, and a fixed roller and a movable roller are respectively provided between the left support and the fixed platform 1 and the fixed platform 2. In the present invention, the position of the movable roller is adjusted according to the diameter of the milling cutter raw material, the driving motor 2 drives the driving gear to rotate, the driving gear drives the large gear ring to rotate, the large gear ring drives the gear to rotate through the support rod, and under the limiting action of the small gear ring, the gear rotates in a circle around the small gear ring, and the circular motion of the gear drives the eccentric block to move synchronously, and at the same time, the eccentric block slides inside the limiting ring groove, thereby driving the limiting ring groove to move left and right, but the following defects still exist:

[0004] (1) When the milling cutter is processed, the center of rotation of the milling cutter is not positioned and clamped, which can easily cause the milling cutter to slip relative to the roller, resulting in the milling cutter offset and reduced production quality.

[0005] During rolling production, a large amount of heat is generated due to extrusion between the workpiece and the processing equipment. The accumulation of heat inside the equipment will affect the stability of production activities and lead to reduced production efficiency.

[0006] Therefore, we make improvements on this and propose a rolling device for cemented carbide milling cutter forming processing. Utility Model Content
