Description
Technical field
The invention belongs to a kind of mould applications are and in particular to bend the guide pillar of steel bar mould.
Background technology
Steel bar, is a kind of steel of strip, is widely used in automobile making, finishing, building trade, and in different fields
The form closing the steel bar needing to use is different, therefore occurs in that the mould bending steel bar, steel bar is during bending
Need accurately to position it is ensured that the angle that bends accurate, improve the accuracy making parts.During mould matched moulds
One important part of guide-post of die-set, main effect is that the motion to mould is positioned and guides.Mould matched moulds when
Wait it will usually produce certain impulsive force, so that guide pillar is deformed upon, and during guide pillar moves back and forth in guide pin bushing, meeting
Produce friction, thus causing to guide pin bushing and guide pillar to wear and tear, long use can make the precision of guide pillar reduce, and then lose and lead
To effect, therefore can change guide pillar, increased cost.
For solving the above problems, the Chinese patent of Publication No. CN205291360U provides a kind of guide-post of die-set, including
Base, described base is provided with guide pin bushing, and the top of described guide pin bushing is provided with end cap, described end cap is provided with guiding
Hole, described guiding in the hole is provided with guide pillar A, is provided with seal washer between described pilot hole and guide pillar A, described guide pillar
The lower end of A is connected with guide pillar B, and the lower end of described guide pillar B is provided with bearing mounting groove, is provided with described bearing mounting groove
Bearing, the top of described guide pillar A is connected with fixed plate, and between described fixed plate and end cap, the periphery of guide pillar A is provided with again
Position spring, the periphery of the described lower surface guide pillar A of end cap is fixedly connected with buffer rubber gasket.This programme passes through guide pillar B and leads
The inner surface of set connects minimizing frictional force by bearing element, and the back-moving spring also by setting between fixed plate and end cap slows down
The decrease speed of guide pillar, thus decreasing abrasion, reducing the probability that guide-post of die-set deforms upon, extends the use longevity of guide-post of die-set
Life.
But, such scheme there is problems：Existing utilization bearing is rolled with guide pin bushing inner surface and is connected minimizing guide pillar
Abrasion, but guide pillar still has the inwall of guide pin bushing during declining to rub, and leads to guide pillar abrasion, and uses
Relatively costly, complex structure.
Content of the invention
The invention is intended to providing the guide pillar bending steel bar mould, can not effectively reduce guide pillar abrasion to solve prior art
, and relatively costly, baroque problem.
For achieving the above object, the present invention provide following technical scheme, the guide pin bushing being connected with whorl of base including base and
Guide pillar body, guide pillar body includes guide pillar A and guide pillar B, and the top of described guide pin bushing is provided with end cap, and the center of end cap has guiding
Hole, guide pillar A is installed in pilot hole, is provided with seal washer, the top of guide pillar A between the outer wall of the inwall of pilot hole and guide pillar A
Portion is provided with block, is provided with back-moving spring between block and described end cap, and the bottom of guide pillar A is connected with guide pillar B, described guide pillar B
It is slidably connected with the inwall of described guide pin bushing, between the inwall of described guide pin bushing and guide pillar B, be provided with oil storage portion and the baffle plate tilting, and
The side that oil storage portion is contacted with guide pillar B is rubber, and the top in oil storage portion has opening, and baffle plate is located at the top in oil storage portion, and keeps off
One end that plate is connected with the inwall of guide pin bushing is low side, and the opening in described oil storage portion is offseted with baffle plate, is placed with described oil storage portion
Fluid oil.
The know-why of this programme is：During guide pillar declines, back-moving spring can subtract to the power of one buffering of guide pillar
The speed that slow guide pillar declines, guide pillar B extrudes oil storage portion when declining, and the fluid oil placed in oil storage portion will be from opening
Flow out, and fluid oil is blocked by baffle plate, flows down near the side of guide pillar then along oil storage portion, at this moment the inwall of guide pin bushing just adheres to
There is fluid oil, decrease the friction of guide pillar B and guide pin bushing, reduce abrasion, and this device effect is good, low cost, structure are simple.
What this programme can produce has the technical effect that：Back-moving spring serves the effect of buffering, slow down the speed of guide pillar decline
Degree, reduces the possibility of guide pillar deformation, the fluid oil placed in oil storage portion, is extruded so that leading during guide pillar declines
Friction between post and guide pin bushing reduces, reduce abrasion it is ensured that guide pillar guiding accurate, and this device slow down abrasion
Effect is good, low cost, and structure is simple.
The following is the preferred version based on such scheme：
Preferred version one：The side wall of described guide pin bushing is provided with oiling pipeline, and oiling pipeline is connected with the top in oil storage portion.In oil storage
After fluid oil in portion is extruded, can continue adds fluid oil in oil storage portion, keeps the inwall of guide pin bushing to be unanimously attached with
Fluid oil, reduces abrasion.
Preferred version two：Based on preferred version one, described oiling pipeline is obliquely installed, and described oiling pipeline is arranged on guide pin bushing
Outer wall one end be higher than be arranged on guide pin bushing inwall one end, the oiling pipeline being obliquely installed, in oil storage portion refuel when,
Fluid oil can voluntarily be flowed in oil storage portion.
Preferred version three：Based on preferred version two, the high-end of described oiling pipeline is provided with a piston, in oil storage portion
After filling it up with oil, if oil storage portion is squeezed, fluid oil may be extruded from oiling pipeline, and piston can prevent fluid oil quilt
Extruding is gone out.
Preferred version four：Based on base case, described base is provided with Oil Guide passage, and described Oil Guide passage is along in guide pin bushing
The bottom setting of wall, Oil Guide passage can make fluid oil flow to outflow during guide pin bushing bottom, will not accumulate guide pin bushing bottom, impact is led again
Post guide-localization.
Preferred version five：Based on preferred version four, the bottom of described Oil Guide passage connects fluted, the side of described groove
It is connected with petroleum pipeline, groove can collect the fluid oil that guide pin bushing inwall flows down, and is exported along petroleum pipeline, carry out profit next time
With.
Preferred version six：Based on preferred version five：Described petroleum pipeline is obliquely installed, and the side of petroleum pipeline connecting groove is higher than
Opposite side, the fluid oil in groove, can be exported along petroleum pipeline under gravity.
Preferred version seven：Based on base case：The bottom of described guide pin bushing is provided with rubber blanket, and the bottom of rubber blanket is fixed on
On base, rubber washer can be to the effect of one buffering of guide pillar.
Preferred version eight：Based on base case：The bottom of described guide pin bushing periphery is provided with positioning sleeve, and the bottom of positioning sleeve is fixed
On base, because guide pin bushing is threadeded with base, so guide pin bushing may pitch during using, positioning sleeve can
