Abstract
It offsets the utility model discloses a kind of circular die and adjusts structure, it includes die holder and circular die that the circular die, which offsets and adjusts structure, the die holder is provided centrally with circular pilot hole, the circular die fixing assembling is in pilot hole, wherein, the side wall of the circular die is peripherally disposed several notches, is provided with adjustment block in the notch, the medial surface of the adjustment block is close to the inner wall setting of notch, lateral surface be close to be arranged with die holder it is arc-shaped.Above-mentioned circular die offsetting adjustment structure is not only simple in structure, convenient for operation；And mold offsetting effectively can be measured and adjust, it is at low cost.
Description
Technical field
The utility model relates to a kind of mould structures, offset more particularly, to a kind of circular die and adjust structure.
Background technique
When forging mold design, for save the cost, only the product of a small number of special constructions needs to match using unitary mould
It closes forging equipment to be produced, most of product all considers to substitute unitary mould by particular manufacturing craft and all round die holder combination.
And in the design of particular manufacturing craft and all round die holder assembly, it is contemplated that flexible deformation will not occur in assembling process for cold conditions mold
(not being available interference fit) and mold heating after exist thermal expansion phenomenon (it is stuck in die holder after die swell, in the short time
Can not dismantle), therefore the cooperation of the two must be transition fit, and there are gaps, since then mold can be in die holder there are gap
It is mobile, only can be in vertical both direction activity different from square mold, circle mold is movable in all directions, can not have after forging
Imitate to obtain measurement and adjustment mold offsetting.
Utility model content
It offsets the purpose of this utility model is to provide a kind of circular die and adjusts structure, it is round in the prior art to solve
The problem of mold offsets effectively can not be measured and adjust after mold forging.
For this purpose, the utility model uses following technical scheme:
A kind of circular die offsetting adjustment structure comprising die holder and circular die, the die holder are provided centrally with circle
Pilot hole, the circular die fixing assembling is in pilot hole, wherein the side wall of the circular die is peripherally disposed
There are several notches, adjustment block is provided in the notch, the medial surface of the adjustment block is close to the inner wall setting of notch, outside
Face be close to die holder setting it is arc-shaped.
Particularly, arc gap there are four uniformly being opened up on the side wall of the circular die.
Particularly, the inner wall of the arc gap is bevel structure, and the medial surface of the adjustment block is fit circular arc notch
Inner wall setting inclined-plane.
Particularly, threaded hole is offered at the top of the adjustment block.
The beneficial effects of the utility model are that the circular die, which offsets, compared with prior art adjusts structure not only structure
Simply, convenient for operation；And mold offsetting effectively can be measured and adjust, it is at low cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the circular die offsetting adjustment structure that specific embodiment of the present invention provides；
Fig. 2 is the side view of the adjustment block for the circular die offsetting adjustment structure that specific embodiment of the present invention provides
Figure；
Fig. 3 is the vertical view of the adjustment block for the circular die offsetting adjustment structure that specific embodiment of the present invention provides
Figure.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Shown in please referring to Fig.1 to Fig.3, in the present embodiment, a kind of circular die adjustment structure that offsets includes die holder 1 and circle
Mold 2, die holder 1 are provided centrally with circular pilot hole 3, and 2 fixing assembling of circular die is in pilot hole 3, the side of circular die 2
Wall is along the circumferential direction uniformly opened up there are four arc gap, is provided with an adjustment block 4, adjustment block in arc gap with can be removably mounted
4 medial surface 40 is close to the inner wall setting of arc gap, lateral surface 41 be close to be arranged with die holder 1 it is arc-shaped.
The inner wall of arc gap is bevel structure, and the medial surface 40 of adjustment block 4 is that the inner wall of fit circular arc notch is arranged
Inclined-plane, the end face of adjustment block 4 offer threaded hole 5, and position of the circular die 2 in die holder 1 is fixed, and can not move (i.e. round
Mold 2 and 4 gap of adjustment block are 0, and adjustment block 4 and 1 gap of die holder are also that 0), by using the adjustment block 4, circular die 2 is first
It is secondary when being mounted in die holder 1, it can be ensured that circular die 2 is as far as possible at 1 center of die holder.
Above-mentioned circular die, which offsets, adjusts the installation method and adjustment offsetting method of structure are as follows:
Step 1, mold is installed for the first time, is first installed the mold of upper and lower mould into corresponding die holder, then by adjustment block 4
It is packed into the correspondence notch opened up on circular die 2, position of the circular die 2 in die holder 1 is fixed, and can not be moved；
2) after forging initial workpiece produces and offsetting is detected, testing result finds forging, and there are 2mm offsettings, i.e. lower die in X-direction
It is whole to offset by 2mm to X-direction；
3) upper mold is taken out two adjustment blocks 4 of the X-direction of lower die and Y-direction, Y-direction is X-direction without offsetting
Relative direction, the adjustment block for replacing X-direction is thickness -1mm specification adjustment block, and the adjustment block for replacing Y-direction is thickness+1mm
The adjustment block of specification, i.e., it is lower die is whole to Y-direction offset 2mm；
4) adjustment continues to produce after offsetting, and it is 0.5mm that detection forging, which offsets, adjusts and offsets effectively, so repeats step 3)
Method of adjustment, until detection forging offsets in allowed band.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes
Change and change is fallen within the scope of the claimed invention.The utility model requires protection scope is wanted by appended right
Ask book and its equivalent thereof.
