Abstract

The utility model relates to a steel plate blanking frame in the steel and iron manufacturing industry, in particular to a blanking frame of a numerical control cutting machine. The blanking frame comprises laths and iron castings, wherein the laths are longitudinally fixed on a base frame below the blanking frame and the iron castings are inserted on the laths through grooves at the bottom. The laths can be protected by the iron castings and the iron castings can be together processed and repeatedly used after being used for a period of time, therefore, the cost can be saved and the cutting quality can be stably ensured for a long time.

Description

Numerical control cutting machine blanking bin

Technical field

The utility model relates to the manufacturing steel plate cutting bin of a kind of iron and steel, is specifically related to a kind of numerical control cutting machine blanking bin.

Background technology

The used steel construction of performing comprehensive coal mining machinery equipment is to be made up of a large amount of Numerical control cutting plates, and the bin that when cutting steel plate, mainly uses has two kinds of forms: (1) steel plate to be cut directly is layered on and realizes cutting on some 6mm-10mm lamellars; (2) steel plate to be cut directly is layered on and realizes cutting on the equal leg angle.

After cutting flame is cut steel plate to be cut in cutting process; Flame can directly switch on the backing plate of above-mentioned two kinds of forms; Cause thin plate or angle steel when cutting, to be cut, just can produce whole piece thin plate or angle steel when cutting for a long time owing to the some very dense of being cut by flame damages.Thin plate or angle steel are directly contact with the flame of cutting simultaneously; Transversely deforming of being heated and linear deformation are very big, can occur being uneven after use a period of time, make the thickness of cutting steel plate produce; Directly influence the blanking quality; And when changing, bother very much, increase cost of labor, cause production cost bigger.

Summary of the invention

The technical problem that the utility model will solve provides a kind of numerical control cutting machine blanking bin, its long service life, and assurance cut quality that can be steady in a long-term has been saved production cost.

In order to achieve the above object, the technical scheme of the utility model employing is:

Numerical control cutting machine blanking bin comprises lath and ironcasting, and said lath is vertically fixed on the pedestal of blanking bin below, and said ironcasting is plugged on the said lath through bottom groove.

In the such scheme, the thickness of said lath is 14mm, and the height of said lath is 100mm.

In the such scheme, it is trapezoidal boss that said ironcasting top is provided with the longitudinal section.

In the such scheme, said ironcasting both sides are provided with the wing plate that contacts with said lath.

Compared with prior art, the beneficial effect of the utility model generation is following:

The utility model is through ironcasting protection lath, and ironcasting can concentrate the processing recycling in use for some time, not only provided cost savings but also assurance cut quality that can long-term stability.

Description of drawings

The overall structure sketch map of the numerical control cutting machine blanking bin that Fig. 1 provides for the utility model embodiment;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the A-A cutaway view.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated.

Referring to Fig. 1, the utility model provides a kind of numerical control cutting machine blanking bin, comprises lath 1 and ironcasting 2.Lath 1 is vertically fixed on the pedestal of blanking bin below load-bearing as stressed support, and the thickness of lath 1 is 14mm, highly is 100mm.Cause weight to increase if lath thickness adds conference, be prone to make the pedestal of load-bearing to produce distortion; Lath thickness reduces, and lath is heated and can produces distortion, reduces service life.Because the lath of selecting for use is thicker, the lath root is every to carry out once fixing apart from 1500mm, makes the long-term temperature distortion of lath less, reaches the stable purpose of using.Ironcasting 2 materials are HT200*220, and single-piece length is 295mm, and are plugged on the lath 1 through bottom groove, lath 1 is protected, and convenient the installation and dismounting.It is trapezoidal boss 4 that ironcasting 2 tops are provided with the longitudinal section; Make ironcasting 2 reduce contact area with steel plate to be cut as far as possible; And can play a supporting role; Purpose is to prevent that gas cutting flame directly cuts on the ironcasting 2 in the process of steel plate cutting, causes the phenomenon of not cutting and can occur a large amount of cutting slag deposits on ironcasting 2.Ironcasting 2 both sides are provided with the wing plate 3 that contacts with lath 1, and its purposes is under the prerequisite that reduces ironcasting 2 weight, increases the contact area with lath 1, when preventing to unload workpiece ironcasting 2 are inhaled the phenomenon of falling from lath 1.

The utility model is protected lath through ironcasting, and ironcasting is installed, convenient disassembly, after being cut in cutting a period of time, can concentrate and process and reuse, and not only provides cost savings but also can assurance cut quality steady in a long-term.Trapezoid boss design on the utility model medium cast iron spare; Can make ironcasting follow steel plate to be cut to reduce contact area as far as possible; And can play a supporting role; Prevent that gas cutting flame directly cuts on the ironcasting in the process of steel plate cutting, cause the phenomenon of not cutting and can occur a large amount of cutting slag deposits on ironcasting.The wing plate design of the utility model medium cast iron spare both sides is under the prerequisite that reduces ironcasting weight, increases the contact area with lath, when preventing to unload workpiece ironcasting is inhaled the phenomenon of falling from lath.

The above is merely the preferred embodiment of the utility model, and not in order to restriction the utility model, common variation that those skilled in the art carries out in the utility model technical scheme scope and replacement all should be included in the protection domain of the utility model.
