Problems solved by technology

However, the existing vertical lathes commonly used for flanges, such as gantry planers or gantry milling machines, the mechanical structure is mainly used for processing round flanges, and cannot process the sealing surface of square flanges.
In addition, square flanges, tube sheets, and flange covers used in some chemical industries are relatively large in size, and have high requirements for dimensional tolerances, shape tolerances, and surface roughness. Existing large-scale processing lathes cannot meet the requirements

Embodiment 1

[0035] Such as figure 1 Shown is a preferred embodiment of a rectangular large flange and tube sheet sealing surface processing device of the present invention, including a milling mechanism, a vertical height adjustment mechanism, a horizontal milling feed mechanism and a platform 1; the milling mechanism is used for milling workpieces; the vertical The height adjustment mechanism is connected with the milling mechanism to adjust the vertical height of the cutter head of the milling mechanism; the horizontal milling feed mechanism is connected with the vertical height adjustment mechanism and is configured to regulate the horizontal milling feed speed of the milling mechanism and the vertical height adjustment mechanism; the platform is It is configured to fix the workpiece to be processed and adjust the position of the workpiece to be processed.

[0036] In the present invention, the workpiece is fixed on the platform, and the vertical stroke of the vertical height adjustmen...

Embodiment 2

[0043] figure 2 Shown is a schematic diagram of the milling mechanism of another preferred embodiment of the present invention.

[0044]At present, there are two main types of speed change for the spindle drive of lathes: one is the spindle motor with gear shifting, the purpose is to reduce the spindle speed and increase the transmission ratio to meet the needs of cutting; the other is the spindle motor through the synchronous toothed belt or V Driven main shaft, this type of driving method does not require mechanical shifting, and the gear and clutch are omitted in the main shaft box, which simplifies the main transmission system and improves the reliability of the transmission chain.

[0045] Considering that the processing of the rectangular and large-sized tube plate sealing surface generally has a small center distance and a large transmission ratio, and the milling process is required to be as smooth as possible without vibration, this embodiment uses a V-belt to drive ...

Embodiment 3

[0048] image 3 It is a schematic diagram of the platform of another preferred embodiment of the present invention.

[0049] In this embodiment, the platform 1 includes a working platform and an adjustment mechanism; the working platform is connected to the adjustment mechanism, and a T-shaped groove, a compression bolt and a nut are arranged on the surface, and the workpiece to be processed is fixed by the T-shaped groove, the compression bolt and the nut; the adjustment The mechanism includes a screw mandrel and a screw nut. Based on the relative positions of the screw mandrel and the screw nut, the center line of the workpiece to be processed on the working platform is adjusted to be on the same straight line as the horizontal feed direction of the cutter head chuck 22 of the milling mechanism. image 3 Among them, the left part is the front view of platform 14, and the right part is the left view of platform 1.

[0050] In order to better configure the positional relation...

Abstract

The invention discloses a rectangular large flange and tube plate seal face machining device. The rectangular large flange and tube plate seal face machining device is characterized by comprising a milling mechanism, a vertical height adjusting mechanism, a horizontal milling feeding mechanism and a platform. The milling mechanism is arranged to mill a workpiece. The vertical height adjusting mechanism is connected with the milling mechanism and arranged to adjust the vertical height of the milling mechanism. The horizontal milling feeding mechanism is connected with the vertical height adjusting mechanism and arranged to adjust and control the horizontal milling feeding speed of the vertical height adjusting mechanism and the milling mechanism. The platform is arranged to fix and adjust the position of the workpiece to be machined. The rectangular large flange and tube plate seal face machining device is simple, practical, economical and reasonable, the vertical and horizontal travelof a tool bit of the milling mechanism can be flexibly adjusted, the roughness of the machined face is low, and the rectangular large flange and tube plate seal face machining device is particularly suitable for fine machining of a rectangular large flange, a tube plate seal face and a flange end face.

Description

technical field [0001] The invention relates to the field of flange processing, in particular to a processing device for a large rectangular flange and a sealing surface of a tube sheet and a method for using it. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. They are widely used in heating, cooling, condenser, evaporation and reboiling processes in chemical production. Flange connection is often used between heat exchanger shaft and shaft. The tightness of the connection between the flange and the tube sheet sealing surface is crucial to the working efficiency and process performance of the heat exchanger. [0003] At present, the processing technology of circular flanges in the manufacture of heat exchangers is relatively mature. But in actual producti...
