Abstract
A kind of 45 degree of rolling depression cutters, comprise base, described base is connected with knife bar cover, be provided with the knife bar of through knife bar cover in knife bar cover, one end of knife bar is provided with roll extrusion cutter hub, and the other end is provided with the regulating nut regulating knife bar to elongate or shorten, described knife bar puts and is provided with dynamometer, and dynamometer is connected with knife bar.The utility model structure is simple, practical.
Description
Technical field
The utility model relates to rolling depression cutter field, is specially a kind of 45 degree of rolling depression cutters.
Background technology
In extrusion process, rolling depression cutter makes workpiece surface produce residual pressure, can improve its fatigue strength and resistance to corrosion.The size of extruding allowance determines the size of required extruding force, and the size of extruding force directly affects squeezing effect.As extruding allowance is excessive, extruding cutter meeting rapid wearing, causes workpiece surface quality to decline; As extruding allowance is too small, then do not reach the object of expection processing.Therefore the size controlling extruding force is accurately one of our problem to be solved.
Traditional rolling depression cutter can not, in specific angle (as 45 degree) to work pieces process, cause reducing the efficiency of work pieces process.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model be to provide a kind of can control extruding force size, can at the rolling depression cutter of miter angle to work pieces process.
For achieving the above object, the utility model provides following technical scheme: a kind of 45 degree of rolling depression cutters, comprise base, described base is connected with knife bar cover, be provided with the knife bar of through knife bar cover in knife bar cover, one end of knife bar is provided with roll extrusion cutter hub, and the other end is provided with the regulating nut regulating knife bar to elongate or shorten, described knife bar puts and is provided with dynamometer, and dynamometer is connected with knife bar.
Further, the fixed block that described base comprises cuboid and the angle modulation plate be connected with fixed block, described fixed block comprises the first plane, and described angle modulation plate comprises the second plane and the 3rd plane, the centerline parallel of the 3rd plane and knife bar.
Further, the angle of described second plane and the 3rd plane is 45 degree.
Further, described first plane and the second plane orthogonal.
Contrast the deficiencies in the prior art, the beneficial effect that the technical scheme that the utility model provides is brought: 1. the utility model effectively monitors extruding force by dynamometer, then by regulating regulating nut to shorten or extending knife bar, control the size of extruding force, effectively prevent from producing excessive or too small extruding force during the roll extrusion cutter hub conflict workpiece in extruding force, the effective quality improving processing work.2. the utility model is by being the design of 45 degree by the angle of the first plane and knife bar on holder, after fixing holder, makes the angle of knife bar and holder be 45 degree, can carry out miter angle processing to workpiece, for the processing of workpiece improves efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of angle modulation plate.
Detailed description of the invention
With reference to Fig. 1-Fig. 2, the utility model is described further.
A kind of 45 degree of rolling depression cutters, comprise base 1, described base 1 is connected with knife bar cover 2, the knife bar 3 of through knife bar cover 2 is provided with in knife bar cover 2, one end of knife bar 3 is provided with roll extrusion cutter hub 4, the other end is provided with the regulating nut 6 regulating knife bar 3 to elongate or shorten, and described knife bar 3 overlaps 2 and is provided with dynamometer 5, and dynamometer 5 is connected with knife bar 3.
Effectively extruding force is monitored by dynamometer 5, when extruding force is excessive, relative adjustment regulating nut 6, knife bar 3 is shortened, make extruding force moderate, when extruding force is excessive, relative regulating nut 6, knife bar 3 is extended, making extruding force moderate, then by regulating regulating nut 6 shorten or extend knife bar 3, controlling the size of extruding force, effectively prevent the roll extrusion cutter hub 4 on knife bar 3 conflict workpiece time produce excessive or too small extruding force, the effective quality improving processing work.
Further, the fixed block 11 that described base 1 comprises cuboid and the angle modulation plate 12 be connected with fixed block 11, described fixed block 11 comprises the first plane 111, and described angle modulation plate 12 comprises the centerline parallel of the second plane 121 and the 3rd plane the 122, three plane 122 and knife bar 3.
Further, the angle of described second plane 121 and the 3rd plane 122 is 45 degree.
Further, described first plane 111 is vertical with the second plane 121.
First plane 111 is as the installed surface of this rolling depression cutter, but, first plane 111 is vertical with the second plane 121, the angle of the second plane 121 and the 3rd plane 122 is 45 degree, and the 3rd plane 122 and the centerline parallel of knife bar 3, make the first plane 111 be miter angle with the center line of knife bar 3, after fixing holder, make knife bar 3 be 45 degree with the angle of holder, miter angle processing can be carried out to workpiece, for the processing of workpiece improves efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, those skilled in the art carries out common change and replaces should being included in protection domain of the present utility model within the scope of technical solutions of the utility model.
