Abstract
The invention discloses an extrusion sleeve which is in a shape of a cylinder. Chamfers between the two end faces and the external circumference surface of the cylinder are 7-15 degrees. According to the extrusion sleeve, the traditional 18-degree chamfers are improved to the chamfers less than 18 degrees; the pressure of a use state of the extrusion sleeve is reduced; the 350-450KN pressure is reduced to the approximately 250KN pressure by changing 18 degrees to 9 degrees to allow the extrusion sleeve to achieve use service state (that is to say, the diameter of the whole excircle of the extrusion sleeve is extruded to 30.5); and the use effect of the extrusion sleeve is not obviously different from that of the extrusion sleeve with the 18-degree chamfers.
Description
Technical field
The present invention relates to extruded sleeve technical field, especially a kind of extruded sleeve.
Background technology
At present, the extruded sleeve using on market shows as Fig. 1, its both ends of the surface 1 are 18 ° with the chamfering of cylindrical 2, the extruded sleeve of this this angle in actual use, the pressure of offer 350～450KN just can make it reach use state (, the whole cylindrical of extruded sleeve is squeezed into 30.5), bothersome effort, not easy to operate.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of extruded sleeve, simple in structure, easy and simple to handle.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of extruded sleeve, for cylindric, the chamfering between both ends of the surface and the outer circumference surface of this cylinder is 7 °～15 °.
Further, this chamfering is 8 °～12 °.
Further, this chamfering is 9 °.
Compared with prior art, the present invention has the following advantages: by the extruded sleeve of 18 ° of chamferings of tradition, be improved to and be less than 18 ° of chamferings, reduced the pressure of extruded sleeve use state, change 9 ° into as 18 °, the pressure that the pressure of 350～450KN is decreased to 250KN left and right just can make it reach use state (the whole cylindrical of extruded sleeve being squeezed into 30.5), and its result of use and chamfering are the effect no significant difference of 18 ° of extruded sleeves.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of extruded sleeve as shown in Figure 2, for cylindric, the chamfering between both ends of the surface 1 and its outer circumference surface of this cylinder is 9 °.Corresponding improvement, can be made as this chamfering the value between 7 °～15 °; Or the value between more preferably 7 °～15 °.
1, the chamfering after adjustment, can improve (extruded sleeve) user's efficiency of construction (working pressure, by original 350KN～450KN, is reduced to present 250KN).
The weight of the extruded sleeve 2, reducing itself, has reduced cost of transportation.
Claims (3)
1. an extruded sleeve, for cylindric, is characterized in that: the chamfering between both ends of the surface and the outer circumference surface of this cylinder is 7 °～15 °.
2. extruded sleeve as claimed in claim 1, is characterized in that: this chamfering is 8 °～12 °.
3. extruded sleeve as claimed in claim 2, is characterized in that: this chamfering is 9 °.
