Description
Technical field
The present invention relates to the production method of the production method of corrugated pipe connector, particularly municipal corrugated pipe connector.
Background technology
Bellows because of its can bear bigger radial load, in light weight, make that efficient is high to be used widely.In existing bellows used, the influence because of each side factors such as transportation, physical features need connect bellows at the scene.Traditional method of attachment is with two bellowss butt joints, utilizes the bellows of hot melt band colligation two butt joints then, and the method must be operated at the scene, and since a side of bellows to contact with ground basically, therefore, when colligation hot melt band and inconvenience.Afterwards, people are in order to overcome above-mentioned defective, at the two ends of bellows jointing, and joint accepted to realize the connection of bellows, but existing joint all gets up by the butt joint sweat soldering, is easy to generate the phenomenon of cracking at joint, thereby influence the life-span of whole bellows system, do not reach the use standard of country, therefore, providing a kind of can necessitate with the joint that bellows has a higher bonding strength.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of corrugated pipe connector, this production method can be fit to the production of the corrugated pipe connector stock of different tube diameters size, and in process of production to the clamping good stability of corrugated pipe connector stock, the security of production is good.
For achieving the above object, a kind of step of production method of corrugated pipe connector is as follows.
(1) special fixture is installed on the chuck of lathe.
(2) with corrugated pipe connector stock clamping to special fixture.
(3) start lathe, an end external diameter of turning corrugated pipe connector stock.
(4) stop lathe, will turn around clamping to special fixture through the corrugated pipe connector stock of above-mentioned steps (3).
(5) start lathe, the spiral step of turning on the external diameter of the corrugated pipe connector stock other end.
(6) stop lathe, the screwed pipe joint of above-mentioned steps (5) is disassembled, finish the production of a corrugated pipe connector.
Wherein, described special fixture comprises fixed disk; Central shaft position at fixed disk is equipped with the axis of guide; Being provided with the fixed disk central shaft at the fixed disk front end face is that the center of circle is at the slide block more than two that radially slides uniform on the circumference, the arc supporter is installed on each slide block, and it is on the same circumference in the center of circle that the outer circumference surface of the arc supporter on each slide block is in the fixed disk central shaft; Be with taper sheath on the described axis of guide; By moving axially taper sheath, each slide block can be on the front end face of fixed disk is radially motion simultaneously of the center of circle with the fixed disk central shaft, thereby regulates the radial motion simultaneously of arc supporter, with the installation and removal of the corrugated pipe connector stock that is fit to the different tube diameters size.
Aforementioned production method, owing at chuck special fixture has been installed, in special fixture by moving axially taper sheath, each slide block then can be on the front end face of fixed disk is radially motion simultaneously of the center of circle with the fixed disk central shaft, thereby regulate the radial motion simultaneously of arc supporter, with the purpose of the installation and removal that reach the corrugated pipe connector stock that is fit to the different tube diameters size.Owing to be provided with supporter, when the corrugated pipe connector stock is installed, the corrugated pipe connector stock is installed on the supporter and can processes, so just can overcome at chuck unsettled defective is installed, make the installation good stability of corrugated pipe connector stock, produce safety.
As improvement, the rear end face of taper sheath is connected with cylindrical sleeve, and cylindrical sleeve is enclosed within on the axis of guide, is formed with containing cavity between the inner peripheral surface of cylindrical sleeve and the axis of guide; The leading section of the axis of guide is provided with screw thread, and at the leading section of the axis of guide rotation loop bar that has been threaded, the rearward end outer circumference surface outward radial of rotation loop bar is extended with flange; Be provided with two thrust ball bearings in the described containing cavity, be formed with the gap between two thrust ball bearings; Described flange places in the gap.This structure is used for moving axially taper sheath, its process is: rotation rotation loop bar, the rotation loop bar is with respect to axis of guide axially-movable, the rotation loop bar is in motion process, flange drives cylindrical sleeve and taper sheath axially-movable, thereby reaches the purpose of mobile taper sheath, the position of the adjustment supporter that this structure can not only be manual, be convenient to clamping corrugated pipe connector stock, and simple in structure.Said structure, owing to be provided with thrust ball bearing, therefore, when the rotation of rotation loop bar, taper sheath will not followed the rotation of rotation loop bar.
As improvement, be provided with radially the patchhole that inserts to instrument at the leading section of rotation loop bar.Like this, be convenient to setting tool, help rotation rotation loop bar.
As improvement, between slide block and taper sheath, be provided with roller on the slide block.After roller is set, become rolling friction by sliding friction between slide block and the taper sheath, thereby reduced the resistance of motion of taper sheath, and avoided the wearing and tearing of slide block, simultaneously, behind rolling wheel wear, do not need to change slide block, only need to change roller and get final product, reduced maintenance cost.
As improvement, the central shaft position that is positioned at fixed disk at fixed disk is equipped with the lead that extends to the fixed disk rear end.This structure, when being installed to fixed disk on the chuck, lead has the guide-localization effect, the axiality between the central axis of raising fixed disk and the central axis of chuck, thereby the machining accuracy of raising parts.
As improvement, the arc supporter comprises skeleton body and arcuate member, and arcuate member is located on the skeleton body, and described skeleton body is hollow structure.The skeleton physical efficiency that is designed to hollow structure alleviates the weight of whole supporter, can reduce consumptive material simultaneously, reduces the manufacturing cost of special fixture.
As improvement, be provided with the reinforcement gusset between slide block and the skeleton body.This structure can improve the bonding strength between slide block and the skeleton body, simultaneously, can improve the radially bearing capacity of supporter.
