Description
Technical field
The present invention relates to hydraulic support for low coal seam, more particularly, to the elongated main reinforcement groove heat of hydraulic support for low coal seam top beam
Cutting method.
Background technique
Hydraulic support is that In Modern Mine exploits important support apparatus, as the high tension coal mining of coal resource in recent years makes
Medium-thickness seam storage level is greatly reduced, girdle coal mine is increasingly becoming main production zone, thus hydraulic support for low coal seam by
Gradually become main support apparatus in coal mine.
One of hydraulic support for low coal seam main feature is exactly that set cap box height is low, as shown in Figure 1；And elongated main reinforcement
Component is the chief component of the set cap body structure, plays the important function for increasing cabinet intensity and rigidity.This is thin
The characteristics of long main reinforcement component is: the ratio between the length of main gusset 1 and the maximum width of main gusset 1 are greater than 10, and the front end of main gusset 1 is
Wedge shape upwarps structure, and the upper and lower edge of main gusset 1 is double groove structure, as shown in Figure 2,3.Currently, main gusset 1 it is upper,
Lower edge groove takes flame thermal cutting to form more, since retaining wall on slope amount is big, leads to 1 width direction bending deformation quantity of main gusset
It is larger, the normal assembled welding that not can guarantee set cap cabinet is caused, which is always to perplex hydraulic support for low coal seam knot
The technical problem of component manufacture.
Summary of the invention
It is an object of that present invention to provide a kind of elongated main reinforcement groove method for hot cutting of hydraulic support for low coal seam top beam, and reaching has
Effect controls the deformation of the elongated main reinforcement groove thermal cutting.
To achieve the above object, the present invention takes following technical proposals:
The elongated main reinforcement groove method for hot cutting of hydraulic support for low coal seam top beam of the present invention, includes the following steps:
The first step, according to blanking drawing measure: cut on high strength steel plate by numerical control cutting machine by rectangular section and
The main gusset that wedge-shaped segment is constituted, the anti-deformation of reserved 0-10mm when main gusset blanking；
The groove of second step, the upper and lower edge of thermal cutting main ribs plate:
A, the groove of thermal cutting main gusset upper edge first；Using gas flame cuttiug machine people from the institute of main gusset when thermal cutting
It states wedge-shaped segment one end to carry out to the other end of main gusset, thermal cutting goes out a slope surface of main gusset upper edge groove, then from master
To the other end of main gusset, thermal cutting goes out a slope surface of main gusset lower edge groove for wedge-shaped segment one end of gusset；
B, after carrying out leveling to the main gusset that is cooled to room temperature using level(l)ing machine, using gas flame cuttiug machine people from main gusset
Wedge-shaped segment one end carried out to the other end of main gusset, thermal cutting goes out another slope surface of main gusset upper edge groove, then from master
To the other end of main gusset, thermal cutting goes out another slope surface of main gusset lower edge groove for wedge-shaped segment one end of gusset；
C, it is heated in the middle part of the wedge-shaped segment lower edge of main gusset using flame, 400-600 DEG C of heating temperature with balanced main reinforcement
Thermal cutting deflection in the heated situation of plate.
To reduce the heat distortion amount that generates in main ribs plate shape blanking process, when the first step blanking, the number
Control cutting machine symmetrically cuts two pieces main ribs plate shape using two bar cutting guns.
The invention is characterized in that the elongated main reinforcement blanking deformation allowance, control groove thermal cutting sequence direction, with
And the thermal deformation correction during beveling and cutting, and then reach the control elongated main reinforcement groove thermal cutting of hydraulic support for low coal seam top beam
Amoebida.It solves the elongated main reinforcement groove thermal cutting of long-standing problem hydraulic support top beam and deforms serious problem, save and adopt
With the expense of mechanical and flame straightening beveling and cutting deformation, reduces and cause elongated main reinforcement component to return since thermal deformation is serious
The probability repair, scrapped improves the quality of production of elongated main reinforcement component.

Specific embodiment
The invention will be described in further detail with reference to the accompanying drawing:
The elongated main reinforcement groove method for hot cutting of hydraulic support for low coal seam top beam of the present invention, includes the following steps:
The first step, according to blanking drawing measure: as shown in Figure 4,5, cut on high strength steel plate 9 by numerical control cutting machine
Under the main gusset that is made of rectangular section 3 and wedge-shaped segment 2, when blanking, as shown in figure 8, numerical control cutting machine uses two bar cutting guns pair
Claim cutting two pieces main gusset, to reduce the heat distortion amount of main gusset shape；Since main gusset cutting deformation is mainly front end wedge shape
2 positions of section are bent upwards deformation, therefore, according to the material of main gusset, plate thickness and form factor when drawing blanking drawing, by wedge
The front end position of shape section 2, which integrally moves down, reserves certain anti-deformation, i.e., practical blanking figure upwarps F drafting of taking measurements
At F=(E- 10) mm, 10mm anti-deformation is reserved, E is design drawing size；
The groove of second step, the upper and lower edge of thermal cutting main ribs plate, as shown in Figure 6,7:
A, the groove of thermal cutting main gusset upper edge side first；Use gas flame cuttiug machine people from main gusset when thermal cutting
2 one end of the wedge-shaped segment to the other end of main gusset, thermal cutting goes out a slope surface 4 of main gusset upper edge groove, then again
From 2 one end of wedge-shaped segment of main gusset to the other end of main gusset, thermal cutting goes out a slope surface 5 of main gusset lower edge groove；
B, after carrying out leveling to the main gusset that is cooled to room temperature using level(l)ing machine, using gas flame cuttiug machine people from main gusset
2 one end of wedge-shaped segment to the other end of main gusset, thermal cutting goes out another slope surface 7 of main gusset upper edge groove, then again from
To the other end of main gusset, thermal cutting goes out another slope surface 8 of main gusset lower edge groove for 2 one end of wedge-shaped segment of main gusset；Extremely
This, completes the thermal cutting of the upper and lower edge groove of main gusset.
C, (oval position 6 in Fig. 6) in the middle part of 2 lower edge of the wedge-shaped segment of main gusset is heated using flame, heating temperature
The 400-600 DEG C of thermal cutting deflection being heated in situation with balanced main gusset.
As shown in figure 8, to reduce the heat distortion amount that generates in main gusset shape blanking process, when first step blanking, numerical control
Cutting machine on high strength steel plate 9, is symmetrically cut into two pieces according to arrow direction from starting point 10,11 respectively using two bar cutting guns
The shape of main gusset.
