Problems solved by technology

However, in the actual press-fitting process, it often happens that the muffler cylinder has cracks or the inner core cannot be normally pressed into the proper position, which greatly reduces the performance of the muffler. In the process, the fixing of the sound-absorbing cylinder is loose, which makes the inner core swing radially in the cylinder, which leads to the failure of press-fitting

Embodiment 1

[0023] Such as figure 1 As shown, this embodiment includes the following steps:

[0024] (A) Place the muffler cylinder in the conical cavity until the outer wall of the muffler cylinder is in contact with the inner wall of the through hole. At this time, the driving device is activated to make the crossbar start to move downward, and the chuck at the end of the fixed plate is Directly hug the outer wall of the muffler cylinder to move it along the axis of the fastener;

[0025] (B) The rubber ring is in direct contact with the outer wall of the muffler cylinder when it moves downwards to prevent the outer wall of the muffler cylinder from being hardly damaged. At the same time, when the pressing part acts on the inner core, the muffler cylinder can continue to drop in the through hole Move a certain distance, that is, buffer movement, until the bottom of the muffler cylinder contacts the upper end of the push rod, restrict the continued movement of the muffler cylinder, and ensur...

Abstract

The invention discloses a silencer inner core press-mounting device use method. According to the method, when a pushing assembly acts on an inner core, a silencer cylinder body moves a section distance continuously till the bottom of the silencer cylinder body is in contact with the upper end part of a push rod, and then the continuous move of the silencer cylinder body is limited to ensure stable fixing of the silencer cylinder body in the press mounting process of the inner core, so that three-point clamping of the silencer cylinder body is realized, and deflected displacement or radial run-out of the silencer cylinder body during press mounting is avoided, the fastening of the silencer cylinder body can be ensured during the pushing of the inner core, and the purpose of improving the inner core press mounting efficiency is realized accordingly.

Description

Technical field [0001] The invention relates to a pressing machine, in particular to a method of using a muffler inner core pressing device. Background technique [0002] In order to meet the increasingly stringent requirements of environmental protection regulations, enterprises in many countries are studying the technology of mass production of cartridge purifiers. Most of the existing cartridge purifying mufflers have their air outlets set in the center of the circle. The manufacturing technology of this type of purifier has been It is very mature and can be directly pressed into production. However, in the actual press-fitting process, cracks in the muffler cylinder or the inner core cannot be properly press-fitted to the proper position often occur, which greatly reduces the working performance of the muffler. The reason is that the process of pressing the inner core In the silencing cylinder, the fixing of the muffler cylinder is loosened, causing the inner core to swing r...
