Description
Technical field
The utility model relates to tooling cost field, more particularly, relates to a kind of frock preventing thin rolling shearing blade tempering to be out of shape.
Background technology
Thermal treatment is requisite one important procedure in tool sharpening process, is directly connected to use properties and the work-ing life of cutter.But, tempering distortion having the greatest impact to thermal treatment quality.Serious tempering distortion is often difficult to be revised by last precision work, result make workpiece because of dimension overproof or morpheme overproof and scrap, cause the loss of previous each procedure human and material resources, add the cost of enterprise.
High precision rolling shearing blade is the main product of a lot of cutter manufacturing enterprise, and the quality of quality is directly connected to the ups and downs of enterprise.Therefore, the requirement of high precision rolling shearing blade to planeness is high.Capture tempering distortion to become cutter manufacturing enterprise and produce the technical bottleneck that qualified high precision rolling shearing blade must break through.In prior art, due to the support in stove during heating and cooling of the deadweight of the machining state before the structural shape of high precision rolling shearing blade, raw material quality, thermal treatment, blade and blade or clamp the factor such as improper blade all can be caused to be out of shape.To be revised by last precision work when there is tempering distortion, but higher to the tooling cost that blade corrects and machining is repaired of tempering distortion.
Thin rolling shearing blade (below 5mm), because specification is thinner, more easily causes the distortion of blade in the process needing high temperature (500-600 degree Celsius) tempering, makes product size be difficult to control, has influence on blade quality.Prior art is in thin rolling shearing blade production process, tempering deflection exceedes the quantity of blade single-edge grinding amount 1/3 often beyond more than 30% of operation total amount, and cutter manufacturing enterprise drops into a large amount of human and material resources for this reason and is out of shape to eliminate tempering the detrimentally affect brought to tool sharpening.In order to eliminate heat treatment deformation in the subsequent fine course of processing, cutter manufacturing enterprise wants to have use up all possible ways.Usually adopt the method for shield smoothing when tool grinding, namely in suction unit (such as MG7340 type suction unit), pad upper which floor thick cloth, blade is placed on cloth again, is convenient to emery wheel by the deformation layer grinding of blade.But make in this way, blade easily flies out in the process of grinding, very easily causes industrial accident.
Chinese Patent Application No.: 201320026043.8, publication date: on 06 26th, 2013, invention and created name is: a kind of frock of processing and heat treatment distortion cylinder blade, this application case discloses the frock of a kind of processing and heat treatment distortion cylinder blade, comprise sucker, also comprise shaft collar and screw, described sucker is disc, and there is the first screw in the centre of sucker; Described shaft collar is disc, and there is the second screw in the centre of shaft collar; Described sucker and shaft collar are connected by screw; Described screw is through the first screw place being connected to sucker after the second screw.This utility model weakens the magnetic attraction of suction unit to cylinder blade in use, make the strong magnetic influence not being subject to suction unit during the deformation layer grinding of slitter cylinder blade, improve the precision of processing, avoid cylinder blade to rebound at loss of excitation after strain layer, due to what eliminated by wheel grinding when deformation layer ties up to basic loss of excitation, avoid rebound phenomena.The blade that this utility model is applicable to be out of shape carries out the frock of grinding, and the use of sucker can not be applicable to the temper of blade.
