Abstract
The utility model relates to a base for blanking of double-face oblique-head section steel. The upper surface and the lower surface of the base are both horizontal planes. A V-shaped groove which has a 90-DEG included angle is equipped on the upper surface of the base. Wherein, one inclined plane of the V-shaped groove and the base upper surface are at an included angle x which is equal to the section steel rotating angle. By adopting the above mentioned technical scheme, the utility model base can help users easily obtain the section steel blanking with a precise spatial angle (namely, double-face oblique-head) and solve the blanking difficulties during a vehicle frame producing process.
Description
Technical field
The utility model relates to a kind of shaped steel (rectangular steel pipe) blanking servicing unit, especially a kind of two-sided plagiocephaly shaped steel blanking base.
Background technology
The full-bearing type vehicle frame claims the truss-like vehicle frame again.This configurational formula vehicle frame is welded by the steel pipe combination, has the effect of vehicle frame and vehicle body concurrently, and it is big that it has rigidity, the advantage of light weight.The full-bearing type vehicle frame is used in the high-grade bus more and more wider at home, but the space diagonal brace of such vehicle frame (shaped steel (rectangular steel pipe) with space plagiocephaly) blanking, never method accurately.Conventional sawing machine baiting method: after workpiece (shaped steel (rectangular steel pipe)) clamps, the downward feeding cutting of workpiece top saw blade (or below saw blade make progress feeding cutting), by adjusting the cutting angle of saw blade, can obtain non-angular or single angle plagiocephaly (as Figure 1-3), but can't obtain two-sided plagiocephaly.
The utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple structure, two-sided plagiocephaly shaped steel blanking base easy to use are provided.
For achieving the above object, the utility model adopts following technical proposals:
A kind of two-sided plagiocephaly shaped steel blanking base, the upper and lower surface of described base is horizontal plane, opens an angle on the upper surface of base and be 90 ° V-type groove, and wherein the angle of the V-type groove inclined-plane and base upper surface is that angle is x, and x is the shaped steel anglec of rotation.
Described shaped steel anglec of rotation x is: x=tan
-1(tan b/tan a), wherein, a is shaped steel inclined-plane and vertical plane angle, and b is shaped steel inclined-plane and horizontal plane angle, and a, b are the actual known quantity that adds man-hour.
The utility model adopts technique scheme, can help the user to obtain the blanking of the accurate space angle (two-sided plagiocephaly) of shaped steel, has solved a blanking difficult problem in such vehicle frame production.Former blanking will be cut 2 times at least, and angle is inaccurate, and plagiocephaly needs reconditioning, and when welding butt joint slit is big, and weld interval is long.Adopt servicing unit of the present utility model, only need 1 cutting, angle is accurate, and during welding, opposite joint is even, convenient welding.Compare production efficiency with former blanking and improve 50% at least.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Fig. 4-12, a is shaped steel inclined-plane and vertical plane angle, and b is shaped steel inclined-plane and horizontal plane angle, and a, b be the actual known quantity that adds man-hour, and A is the shaped steel height, and B is the shaped steel width, and X is the shaped steel anglec of rotation,
Be the saw blade anglec of rotation, end points I, end points II. end points III is respectively three end points of space plagiocephaly.
Two-sided plagiocephaly shaped steel baiting method may further comprise the steps:
1). according to shaped steel anglec of rotation x, make formed steel base 5; It is that to open an angle on the upper surface of the base that is horizontal plane up and down be 90 ° V-type groove that formed steel base 5 is made, and wherein the angle of the V-type groove inclined-plane and base upper surface is that angle is x.
2). shaped steel 1 is fixed on clamping on the formed steel base 5, and the cutting angle of adjusting saw blade is
Cutting promptly obtains space angle plagiocephaly accurately.
Shaped steel anglec of rotation x is: x=tan
-1(tan b/tan a),
The cutting angle of saw blade is
For:
An angle x ° of shaped steel 1 (rectangular steel pipe) of rotation, this moment plagiocephaly face end points I 2, end points II 3. end points III4 is in straight line (changing F into to figure, as shown in Figure 8 by vertical view), and this line and shaped steel (rectangular steel pipe) length direction angle is
Be the cutting angle of saw blade, this moment, the clamping work pieces cutting promptly obtained two-sided plagiocephaly.
According to the numerical value (known) at two-sided oblique angle, derive the anglec of rotation x of shaped steel (rectangular steel pipe) and the cutting angle of saw blade
It is as follows to derive: when end points I2, end points II3. when end points III4 is in straight line,
T/M＝S/N
T is the vertical range between end points II 3 and the end points III4, and M is the horizontal range between end points II 3 and the end points III4, and S is the vertical range between end points I 2 and the end points II 3, and N is the horizontal range between end points I 2 and the end points II 3.
Can get: tan x=tan b/tan a
Obtain: the anglec of rotation of rectangular steel pipe: x=tan
-1(tan b/tan a)
The cutting angle of saw blade:
According to space angle a, the b (known quantity) that workpiece requires, obtain x,
By the formula function of excel table, can obtain easily x,
Following table is three concrete examples:
The utility model adopts technique scheme, can obtain the blanking of the accurate space angle (two-sided plagiocephaly) of shaped steel, has solved a blanking difficult problem in such vehicle frame production.
