Description
Technical field
When the utility model relates to the metal material Plastic Forming fast to mould, specifically be kind of the Plastic Forming quick mode device of mould up and down, the application when being applicable to the part Plastic Forming in the batch process and needing again to mould because of overhaul of the equipments, mould maintenance, die change etc.
Background technology
At present, during Plastic Forming up and down mould the mould centering not have unified, suitable device, mainly be the operative employee by rule of thumb or adopt the method for on patrix, finishing pigment to adjust the upper and lower mould gap, general centering is promptly tried formation of parts then earlier.Actual size, precision according to the examination formation of parts are adjusted the upper and lower mould gap again, need like this through repeatedly mode transfer, die trial repeatedly, and the low and waste part blank of efficient need consume for a long time sometimes, has influenced the raising of production efficiency, has caused unnecessary waste of material.
Summary of the invention
The purpose of this utility model is just at the above-mentioned existing quick mode device of mould up and down when providing a kind of Plastic Forming to existing weak point in the mold process.
Research mechanism of the present utility model is: according to mechanical analysis, power press is descending by the inside and outside inclined-plane of mode device is decomposed into radial load and axial force, thereby makes counterdie can move freely centering to the center.The unique distinction of this device be the profile of the inner cavity of last die head and lower die head make the band certain taper, have the simplest conical structure, contiguous block then is general, interchangeability is strong.
The purpose of this utility model realizes by following technical measures:
The Plastic Forming of the present utility model up and down quick mode device of mould comprises die head, lower die head and is arranged on contiguous block between the upper and lower die head; Wherein, die head bottom center position is provided with the post that is threaded that extends vertically downward on described; Be provided with the post that is threaded that extends vertically upward at described lower die head end face center position; On two planes up and down of described contiguous block, be provided with the upper and lower screw-threaded counterbore that is connected with the post that is threaded of upper and lower die head respectively in mode with upper and lower die head coaxial line; Mode with central lines between described last die head, contiguous block and lower die head three combines by threaded post, hole; The described end face of going up die head is processed with a cavity, this cavity be its internal diameter from the bottom to top, by little gradually big conical cavity; Described lower die head be its diameter from the bottom to top, by little gradually big conical solid.
Operation principle of the present utility model is as follows:
At first will go up die head and contiguous block links together, and then connect to form die sleeve with lower die head, die sleeve being put in the counterdie die cavity, put then dynamic compressor descending with patrix contact to die sleeve, slowly descending, make die sleeve is driven whole counterdie to move freely centering, like this upper and lower mould promptly on same axis also promptly with one heart.The radially fastening counterdie of elder generation axially fastens counterdie again, thereby has guaranteed counterdie and patrix center then.With the press backhaul, utilize the press liftout attachment at last, promptly finish whole upper and lower mould the die worker is done die sleeve is ejected.
In device of the present utility model, described contiguous block is a universal component, can use repeatedly.
Advantage of the present utility model is as follows:
1, mode device is simple in structure, and processing and manufacturing is easy.
2, utilize this mode device, rapid to mould, centering is effective, precision is high.Labour intensity is low, and the efficient height has been avoided the waste of die trial blank.
Application when 3, this device is applicable to the Plastic Forming of part in the batch process and needs again to mould because of Plastic Forming such as overhaul of the equipments, mould maintenance, die changes, versatility, practicality are very strong.
Description of drawings
Accompanying drawing is the utility model plastic forming device structural representation.
Sequence number among the figure: the 1st, last die head, the 2nd, contiguous block, the 3rd, lower die head
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, Plastic Forming of the present utility model up and down the quick mode device of mould comprise die head 1, lower die head 3 and be arranged on contiguous block 2 between the upper and lower die head; Wherein, die head 1 bottom center position is provided with the post that is threaded that extends vertically downward on described; Be provided with the post that is threaded that extends vertically upward at described lower die head 3 end face center positions; On two planes up and down of described contiguous block 2, be provided with the upper and lower screw-threaded counterbore that is connected with the post that is threaded of upper and lower die head respectively in mode with upper and lower die head coaxial line; Mode with central lines between described last die head 1, contiguous block 2 and lower die head 3 threes combines by threaded post, hole; And the described end face of going up die head 1 is processed with a cavity, this cavity be its internal diameter from the bottom to top, by little gradually big conical cavity; Described lower die head 3 be its diameter from the bottom to top, by little gradually big conical solid.
Concrete assembling mode of the present utility model is as follows: will go up die head 1 earlier and link together with contiguous block 2, and then connect to form die sleeve with lower die head 3, afterwards die sleeve being put in the counterdie die cavity, put then dynamic compressor descending with patrix contact to die sleeve, slowly descending, make die sleeve is driven whole counterdie to move freely centering, like this upper and lower mould promptly on same axis also promptly with one heart; The radially fastening counterdie of elder generation axially fastens counterdie again, thereby has guaranteed counterdie and patrix center then; With the press backhaul, utilize the press liftout attachment at last, promptly finish whole upper and lower mould the die worker is done die sleeve is ejected.
