Abstract
The invention relates to a reaming work fixture. The reaming work fixture is composed of a vice, an extrusion female die and an extrusion core rod, and is characterized in that the extrusion female die is formed by connecting a flange section with an installation section; the extrusion core rod is formed by connecting a rod body with an extrusion die head, and the diameter of the rod body is smaller than that of the extrusion die head by 2-3 mm; and the installation section of the extrusion female die is clamped by vice jaw iron of the vice, the extrusion core rod is clamped by a telescopic head of the vice, and the extrusion female die and the extrusion core rod are concentric. The reaming work fixture is simple in structure, easy to manufacture and low in cost; the extrusion female die and the extrusion core rod are just needed to be arranged on the vice jaw iron and the telescopic head of the vice in a clamped mode correspondingly, assembling and installing are easy and convenient, and the installing and center adjusting time is shortened; the diameter of the rod body of the extrusion core rod is smaller than that of the extrusion die head, and die removal is easy; the top of the extrusion die head is provided with a circular-arc chamfer, so that the inner surface of a part cannot be damaged during reaming; and the percent of pass is high, operation is easy, the assembling and disassembling time is shortened, the manufacturing cost is reduced, and the practicality is good.
Description
Technical field
The present invention relates to a kind of frock, and in particular to a kind of reaming frock clamp for reaming.
Background technology
The reduction that is processed as of thin-walled neck bush deforms, and improves its qualification rate, is generally carried out in two steps, first punching press, then reaming.
Punching press ensures the outside dimension required precision of neck bush, and reaming ensures the internal diameter size required precision of neck bush.Routine is in pressure
Reaming, this expanding method are extruded on power machine, it is necessary to make special cold extrusion die, Making mold is costly, manufacturing time
It is long, due to being thin-walled parts, during the demoulding, part deformation is easily caused, the qualification rate of thin-walled neck bush is low.This is accomplished by a kind of mould
Production Time is short, expense is low, the demoulding is readily used for the frock clamp of thin-walled neck bush part reaming.
The content of the invention
Shortcoming the invention aims to overcome above-mentioned technology, there is provided a kind of simple structure, it is easy to manufacture, use operation
It is convenient, for the reaming frock clamp of thin-walled neck bush part.
Reaming frock clamp of the invention, including bench vice, it is characterised in that：Extruding is provided with the jaw of described bench vice recessed
Mould；Described Extruding die is T-shaped structure, is connected and composed by flange sections and construction section, and the internal diameter of Extruding die is equal to neck bush
The external diameter of part；The telescopic head of described bench vice is provided with extruding plug；Described extruding plug is connected by barred body and extrusion die
Composition is connect, the diameter of extrusion die is equal to the internal diameter of neck bush part, diameter 2~3 milli smaller than the diameter of extrusion die of barred body
Rice；The construction section of Extruding die is tight by the jaw iron clamp of bench vice, extruding plug by bench vice flexible head clamping, and Extruding die with
Extruding plug is concentric.
In order to preferably realize above-mentioned purpose：
The head of the extrusion die of described extruding plug is provided with 100~200Circular arc chamfering.
The lower anchor ring of the flange sections of described Extruding die is mounting surface.
Reaming frock clamp of the invention, part is few, simple and compact for structure, expense easy to manufacture is low；To need to only extrude recessed
Mould is clamped in the jaw of bench vice and on telescopic head respectively with extruding plug, combines simple installation, reduces the installation aligning time；
The diameter for extruding the barred body of plug is smaller than the diameter of extrusion die, and easily, the head of extrusion die is provided with circular arc chamfering for the demoulding, expands
During hole will not injuring part inner surface, improve part processing qualification rate, it is simple to operate, shorten the process time of part,
The manufacturing cost of part is reduced, practicality is good.

Specific embodiment
Reaming frock clamp of the invention, is made up of bench vice, Extruding die 4 and extruding plug 2.
Extruding die 4 is T-shaped structure, is connected and composed by flange sections 7 and construction section 9.The internal diameter of Extruding die 4 is equal to liner
Cover the external diameter of part.The external diameter of flange sections 7 is bigger than the external diameter of construction section 9 10 millimeters, and the external diameter of construction section 9 is 18 millimeters, is extruded recessed
The internal diameter of mould is 8 millimeters.
Extruding plug 2 is connected and composed by barred body 10 and extrusion die 11.A diameter of 6.4 millimeters of extrusion die 11, extruding
The head chamfering a of die head 11 is 150, a diameter of 4 millimeters of barred body.
The construction section 9 of Extruding die 4 is placed in the jaw of bench vice, mounting surface 8 and platform in the flange sections 7 of Extruding die 4
The end face of the jaw iron of pincers is adjacent to, and the clamping screw of pivoted jaw iron 5 clamps the construction section 9 of Extruding die 4.Extruding plug 2
In the telescopic head 1 of the insertion bench vice of barred body 10, and the fastening nut on telescopic head 1 is tightened, extruding plug 2 is fixed tightly in telescopic head 1
On.
During reaming, stamping forming thin-walled neck bush part 3 is placed in the endoporus of Extruding die 4, neck bush part 3
Upper overturning is adjacent to the upper surface of the flange sections 7 of Extruding die 4, the telescopic head 1 of mobile bench vice, makes extruding plug 2 and extrudes recessed
Mould 4 with one heart, and locks telescopic head 1, is slowly pressed downward telescopic head 1, and the extrusion die 11 for extruding plug 2 is slowly squeezed into liner
In set part 3, when being pressed onto setting position, then slowly lift telescopic head 1, neck bush part 3, extruding are taken out from Extruding die 4
Reaming terminates.
