Description
Technical field
The utility model relates to automobile die field, particularly a kind of automobile die circular hole chamfer device.
Background technology
The corner of automobile die and circular hole all need chamfering, less circular hole chamfering conventionally adopts drilling machine or uses air sander instrument, because of the volume of automobile die own larger, cause carrying inconvenient, lengthened the fabrication cycle of mould, and drilling machine equipment cost is higher, air sander needs source of the gas to drive, chamfering efficiency is low again, causes production cost higher.
In view of the above, because chamfering itself does not need too large cutting force, the cutting force that driven by shaking provides is enough to meet its requirement, therefore there have been a lot of driven by shaking chamfering devices to be employed, but current driven by shaking chamfering device, because can not regulate the height of drillstock, if longevity of service, operating personnel standing always or couchant meeting very tired, inconvenient operation, also can affect operating efficiency.
