Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and reality
Execute example, the present invention is further elaborated.Only it should be appreciated that specific embodiment described herein
It in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 2, the invention discloses a kind of rubber and strut pawl 10, it includes latch spoon the 11st, corpus unguis 12.
Latch spoon 11 and corpus unguis 12 are formed in one structure, it is to avoid sealing-off latch spoon 11 sealing-off is in corpus unguis 12.
Corpus unguis 12 includes pawl point the 13rd, pawl body the 14th, claw bar 15, and pawl body 14 is connected pawl point 13 and claw bar 15,
And pawl point the 13rd, claw bar 15 lays respectively at and makes relative pawl point the 13rd, the pawl of pawl body 14 in parallel two different aspects
Bar 15 tilts.Pawl point the 13rd, pawl body the 14th, claw bar 15 is one-body molded makes corpus unguis 12 inherently one-body molded
Structure.
Fixing with latch spoon 11 in claw bar 15 is housed in latch spoon 11, latch spoon 11 is formed in one with claw bar 15
Structure, in the present embodiment, rubber struts pawl 10 and uses cold work die steel material one-body molded, so that latch spoon
11 are formed in one structure with claw bar 15 and make latch spoon 11 realize one-body molded with corpus unguis 12.Cold-working mould
Steel have the feature of high intensity, high tenacity, can meet the requirement preventing from deforming, rupturing required for producing.
Pawl body 14 is arc transition with the intersection of latch spoon 11, i.e. pawl body 14 is connected with the bending of latch spoon 11
Place uses big " R " transition, thus can reduce stress and concentrate, and avoids corpus unguis 12 fracture of root, i.e. avoids pawl
Body 14 connects one end fracture of latch spoon 11.
The length of pawl point 13 is as far as possible more than the length of pawl body 14, in order to can stretch in rubber tube or rubber sleeve.
The present invention verifies through the use of 120 days: all rubber strut pawl and all do not go out during test of many times
Existing problem, can reach 200,000 times without fracture, without deformation.
In addition, the processing technology that rubber struts pawl is adjusted as far as possible: bar forges machining
Heating bending pincers worker correction of the flank shape surface polished side facing cut locating surface.During machining, pawl
Body 14 and the bending junction of latch spoon 11 use big " R " transition, and wedge angle rolling process, during heating bending,
The heat treatment that rubber struts pawl uses bulk heat treatmet as far as possible, and increases surface treatment elimination fine crack.
Bar use have high intensity, high tenacity cold-working grinding tool firm；Forging is the key point of heat treatment, in order to disappear
Except forging crack i.e. fine crack.Rubber struts the original easy fracture of the processing technology customer service of pawl, flexible
Deformation, the problem that cost is high and service life is short.
According to 3 principles determining a plane, at least three rubber struts pawl 10 and may make up a rubber support
Opening apparatus, rubber device for spreading is used for strutting rubber articles (such as rubber tube, rubber sleeve).Refer to Fig. 3,
When this rubber device for spreading is in closure state, rubber articles 16 is set in three rubber of this rubber device for spreading
Strutting on pawl 10, three rubber strut the pawl point 13 mutually concentration of pawl 10 and corresponding pawl point 13 end face structures
Become in spherical；Referring to Fig. 4, when this rubber device for spreading is in softened state, three rubber strut
The pawl point 13 of pawl 10 is separated from each other the diameter of the rubber tube expanding rubber articles 16 or rubber sleeve, by rubber articles
16 strut.This rubber device for spreading in use, three rubber strut pawl 10 the angle opened or close,
Dynamics, speed are consistent as far as possible, it is achieved three-jaw tacit agreement coordinates.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Any modification, equivalent and the improvement etc. made within bright spirit and principle, should be included in the present invention
Protection domain within.
