Abstract

The invention discloses a usage method for an exhaust pipe press-fitting machine. When a pressing part acts on an inner core, a silencing tube body continues to move down a section of distance until the bottom of the silencing tube body makes contact with the upper end of a push rod, continuous moving of the silencing tube body is limited, the stable fixation of the silencing tube body during inner core press-fitting can be guaranteed, three-point clamping of the silencing tube body can be achieved, deflection displacement or radial run-out occurring in silencing tube body press-fitting can be avoided, therefore, fastening of the silencing tube body can be guaranteed when the inner core is pressed, and the purpose of improving the inner core press-fitting efficiency can be achieved.

Description

A kind of using method of blast pipe pressing machine
Technical field
The present invention relates to a kind of blast pipe, specifically refer to a kind of using method of blast pipe pressing machine.
Background technology
In order to meet day by day harsh environmental regulation requirement, the enterprise of many countries is all in the technology of research mass production cartridge type clarifier, existing cartridge type purifying muffler outlet side is arranged on round center mostly, the manufacturing technology of this clarifier is very ripe, can directly carry out press-fiting production.But press-fit in process actual, frequent generation noise reduction cylindrical shell occur crack or in core cannot normally be press fit into suitable position, and then greatly reduce the service behaviour of muffler, trace it to its cause, because press down in process at inner core, the fixing appearance of noise reduction cylindrical shell loosens, and makes inner core radial swing occur in cylindrical shell and cause press-fiting failure.
Summary of the invention
The object of the present invention is to provide a kind of using method of blast pipe pressing machine, making inner core ensure the fastening of noise reduction cylindrical shell when pressing down, and then reach the object that core in raising press-fits efficiency.
Object of the present invention is achieved through the following technical solutions:
A using method for blast pipe pressing machine, comprises the following steps:
(A) noise reduction cylindrical shell is placed in cone-shaped cavity, until the outer wall of noise reduction cylindrical shell and the contact internal walls of through hole, now start driving arrangement, make cross bar start to move down, the chuck the being positioned at fixed head end then direct outer wall by noise reduction cylindrical shell is held the axis made it along securing member tightly and is moved;
(B) in the process that moves down at noise reduction cylindrical shell of rubber ring directly and its wall contacts, to prevent the outer wall of hush pipe body rigid impaired, simultaneously when pressing down parts to inner core effect, noise reduction cylindrical shell can continue to move down a segment distance in through hole, namely movement is cushioned, until the bottom of noise reduction cylindrical shell contacts with the upper end of push rod, the continuation of restriction noise reduction cylindrical shell is moved, and then guarantee that the stability that inner core press-fits period noise reduction cylindrical shell is fixed, by push rod top, act on while through-hole wall and chuck, realize 3 clampings to noise reduction cylindrical shell, thoroughly avoid noise reduction cylindrical shell and press-fit the deflection displacement or circular runout that occur in process, inner core is made to ensure the fastening of noise reduction cylindrical shell when pressing down,
(C) when the lower end major part of noise reduction cylindrical shell enters after in through hole, driving arrangement quits work, and certain spacing is left in the bottom of the end-to-end distance noise reduction cylindrical shell of push rod, restarts the cylinder be fixed in frame, push-down head, under the promotion of cylinder, starts to press down operation to inner core;
In above-mentioned steps, described frame is provided with clamp structure, be connected with just to the push-down head of clamp structure at the output of cylinder, described clamp structure comprises base and is arranged on the securing member on base, have up big and down small cone-shaped cavity at the middle part of described securing member, and be connected with through hole in the lower end of cone-shaped cavity, the internal diameter of described through hole is identical with the external diameter of noise reduction cylindrical shell, the inwall of through hole arranges cannelure, in cannelure, is longitudinally arranged side by side multiple rubber ring; Also comprise mutual cross bar connected vertically and push rod, be fixed with at the two ends of cross bar respectively through the push rod of base, securing member, the end of push rod is connected with fixed head, and the end relative at two fixed heads is provided with chuck.
