Embodiment Construction

[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] figure 1 It is a structural schematic diagram of the target workpiece 1 to be finished by the method of the present invention. The workpiece 1 belongs to a transmission roll in a 20-roller Sendzimir rolling mill. Equally divided plum blossom groove, groove shape see Figure 13 , the working surface is two sides of groove tooth thickness 27.4±0.05mm, the indexing accuracy of the working surface is 0.03mm, and the roughness is Ra0.8μm. According to the machining process, the finishing of the plum blossom groove is arranged under the premise that the workpiece 1 has been quenched, the center holes at both ends have been repaired and coaxial, and the outer circle of the roller body has been finely ground. However, because the hardness of the plum blossom groove is as high as HRC56-59 The bit precision is extremely high, the cutting motion...

Abstract

The invention discloses a method for processing a Sendzimir roll wobbler slot. A grinding device is used in the method. The grinding device comprises a grinding head linkage component, a measuring plate, a centre frame, a V-shaped bracket, a trisection correcting plate, an indexing component and a fixing component which are arranged on a lathe in turn. Under the condition of using the grinding device, the method provided by the invention comprises the following steps: positioning a workpiece; horizontally moving a lathe saddle; driving the grinding head linkage component to move; starting a motor and dry grinding; grinding a first wobbler slot working surface at first; releasing the centre frame; pulling out a bolt and rotating the indexing component so as to index; verifying precision bythe trisection correcting plate; plugging the bolt again and tightly blocking the workpiece, thereby grinding a second wobbler slot working surface at the same side; and similarly, grinding the otherwobbler slot working surfaces at the same side. The wobbler slot working surfaces ground by using the device and the method provided by the invention are low in roughness degree and high in accuracy of form and position.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and relates to a manufacturing process for finishing rolls, in particular to a method for processing plum blossom grooves of Sendzimir rolls. Background technique [0002] The Sendzimir roll is a key transmission roll in the 20-high Sendzimir rolling mill on the current silicon steel plate production line. The hardness is as high as HRC56~59, the indexing accuracy of each working surface is 0.03mm, and the roughness is Ra0.8μm. It is precisely because of the special structure, high precision and high hardness of the plum blossom groove mentioned above that it is difficult for ordinary machine tools and tools to meet its requirements. Finishing requirements have become a technical difficulty in the field of machining. Contents of the invention [0003] The object of the present invention is to provide a method for processing the torx groove of Sendzimir rolls, which s...
