Embodiment 1

[0048] See Figure 1 to Figure 5 , A processing technique for a plate used on an H-shaped long beam. The processing technique includes the following steps: first transport the metal sheet 1 to be processed to the plate feeding unit 5, and then drive the plate feeding pusher 52 along the plate feeding slot 51 Perform a horizontal movement to push the metal sheet 1 to be processed onto the cutting unit 2, and then adjust the strip support seats 21 in the cutting unit 2 to change the distribution of the strip support seats 21 below the metal sheet 1 Density and the distance between the top end of each long strip support seat 21 and the bottom surface of the metal sheet 1. The adjustment operation includes the horizontal movement and vertical movement of the long strip support seat 21. After the adjustment operation is completed, it is suspended above the cutting unit 2 The cutting machine performs a cutting operation on the metal sheet 1.

Embodiment 2

[0051] The basic content is the same as Example 1, the difference is:

[0052] The elongated base 22 is a hollow structure, and a coaxial elongated cavity 221 is opened inside the elongated base 22. One end of the elongated cavity 221 is flush with the end surface of the elongated base 22, and the elongated cavity The other end of 221 is connected with the intake pipe head 222; the plastic ball seat 27 includes a spherical surface 28 and a fixing portion 29, the side circumference of the spherical surface 28 is a spherical structure, and a plurality of The vent hole 272, the top end of the spherical surface 28 is connected with the bottom end of the metal ball 26, the bottom end of the spherical surface 28 is connected with the top end of the fixing portion 29, and the bottom end of the fixing portion 29 passes through the top surface of the elongated base 22 In contact with the elongated cavity 221, the spherical surface 28 is provided with a spherical cavity 281 communicating w...

Embodiment 3

[0054] The basic content is the same as in Example 2, the difference is:

[0055] The spherical cavity 281 includes a hemispherical cavity 282 and a truncated cone cavity 283. The bottom of the hemispherical cavity 282 is communicated with the top of the fixed cavity 291 after passing through the truncated cone cavity 283. The top of the truncated cone cavity 283 is wider than its bottom. The vent hole 272 is arranged along the cross line of the hemispherical cavity 282 and the truncated cone cavity 283. Preferably, the side circumference of the spherical portion 28 has an elliptical spherical structure.

Abstract

The invention provides a machining technology of a sheet for a H-shaped long beam. When the technology is applied, firstly, the metal sheet to be machined is conveyed onto a sheet conveying unit, thena sheet conveying pushing hand is driven to horizontally move along a sheet conveying empty groove, so that the metal sheet to be machined is pushed onto a cutting unit; and then, all strip-shaped supporting seat in the cutting unit are adjusted, so that the distribution density of the strip-shaped supporting seat below the metal sheet is changed and the distance between the top end of each strip-shaped supporting seat and the bottom surface of the metal sheet is adjusted, and after the adjusting operation is finished, a cutting machine suspended above the cutting unit cuts on the metal sheet. According to the technology, the adjustability is high, in addition, the cutting quality can be improved, and debris can be recycled.

Description

Technical field [0001] The invention relates to a metal plate processing technology, in particular to a processing technology of a plate used on an H-shaped long beam. Background technique [0002] Existing thermal power plants need to use a large number of steel structural parts, such as tower crane shells, power generation boiler brackets, tube trusses, etc. Among them, H-shaped and Tian-shaped girders are the most common ones. In the process of manufacturing these girders In this process, the original plate needs to be cut, cut, small plate punched, welded, straightened, polished or painted. Among them, the plate must be cut during the blanking and shearing. [0003] In the prior art, the cutting methods for plates include four types: CNC plasma cutting, CNC flame cutting, CNC hydraulic cutting, and CNC aurora cutting. At the same time, when cutting the plate, it is necessary to place the plate on a certain platform to cooperate with the cutting machine to complete the cutting ...
