Description
Technical field
The utility model is related to mould applications, more particularly to a kind of durable continuously elongated mould of guide cylinder.
Background technology
Continuously elongated mould generally comprises the upper die and lower die of mutual cooperation, because metal belting is between upper die and lower die
Intermittent movement, continuously elongated mould includes some different machining cells, for the same position of metal belting, with metal
The motion of strip, the position is stamped successively in different machining cells, and shape also moves closer to finished product, until finally obtaining
Finished product.
The upper mould of continuously elongated mould descends mould to move relatively, and processing is punched out to material strip.In order to guide the motion of upper mould
Track, lower mould top surface is provided with some leads, and upper mould is provided with guide cylinder corresponding with lead position, during upper mould motion, is oriented to
Cylinder is moved along lead, is prevented from producing skew when mould from moving down, it is ensured that machining accuracy, can be produced between guide cylinder and lead
After raw friction, time length, the aperture of guide cylinder can become big, and the diameter of lead can diminish, and cause guide cylinder and lead
Between there is the movement locus of mould in larger gap, influence, can only be to guide cylinder and guiding so as to reduce the precision of processing
Post is changed, in addition, guide cylinder, which is moved down, can extrude lower mould, change is easily produced after the opposite force that guide cylinder is given by lower mould
Shape, shortens the service life of guide cylinder.
The content of the invention
According to above technical problem, the utility model provides a kind of guide cylinder durable continuously elongated mould, and its feature exists
In including upper die and lower die, lead, guide cylinder, spring, annular slab, round platform sleeve, projection I, projection II, nut, the lower mould
On be provided with and partially pass through lower mould under lead, the lead and be connected with nut thread, the lower mould upper surface and spring one
End connection, the spring other end is connected with annular slab, and the annular slab is enclosed on the outside of lead, on the outside of the lead axially
Projection I is fixed with, described raised I is to be oppositely arranged two-by-two between N number of, N >=4, described raised I, and described raised I is located at annular slab
Top, the upper mould is located above lower mould, and the upper mould lower surface is provided with portion outboard under guide cylinder, the guide cylinder and is cased with
Round platform sleeve, the bottom surface of the round platform sleeve and the bottom surface of guide cylinder are generally aligned in the same plane, and are fixed with the inside of the guide cylinder convex
Rise and be oppositely arranged two-by-two between II, described raised II, described raised II is to open up fluted on N number of, N >=4, described raised II,
The projection I being oppositely arranged is separately installed with two grooves being wherein oppositely arranged.
The upper mould is connected with hydraulic system.
The beneficial effects of the utility model are：Mould is moved up and down in the presence of hydraulic system on the utility model, upper mould
Drive guide cylinder to be enclosed on the outside of lead to move up and down, two relative projections I of lead are located on the inside of guide cylinder respectively
In two relative grooves, the guide effect of raised I pair of groove causes lead to play a part of guiding to guide cylinder, because of friction
When space between groove and projection I becomes big, hydraulic system drives upper mould to be moved up with guide cylinder, guide cylinder and lead point
From, back out nut, rotate lead, make the relative projection I of the another two of lead side respectively with the another two in guide cylinder
Relative fit depressions, when upper mould is moved again, the groove being now engaged plays guide effect with projection I, is so oriented to
Post can be used for a long time with guide cylinder on the premise of the mould moving process under guarantee does not produce skew, that is, ensure that the precision of processing
The service life of guide cylinder is increased again, when guide cylinder moves down pressure annular slab, spring can compress, spring plays buffering and made
With very big impulsive force will not be produced when extruding guide cylinder and annular slab, and guide cylinder is unlikely to deform, and the bottom of guide cylinder is exceptionally
Side is cased with round platform sleeve, and the bottom surface of round platform sleeve and the bottom surface of guide cylinder are generally aligned in the same plane, and increase the floor space of guide cylinder,
The pressure of guide cylinder bottom surface institute stress can be reduced so that guide cylinder is unlikely to deform, extend the service life of guide cylinder.

Embodiment
According to the figure, the utility model is further described for root：
Embodiment 1
The utility model is a kind of durable continuously elongated mould of guide cylinder, it is characterised in that including upper mould 7, lower mould 1, led
To post 2, guide cylinder 8, spring 4, annular slab 5, round platform sleeve 9, projection I 6, projection II 10, nut 3, lead 2 is arranged on lower mould
On 1, lower mould 1 is partially passed through under lead 2 and is threadedly coupled with nut 3, the lower upper surface of mould 1 is connected by spring 4 with annular slab 5,
