Description
Technical Field
The utility model relates to an engineering machine tool technical field.
Background
The transverse shear mainly has the advantages that steel is cut into pieces, the steel is cut off after the upper and lower shear blades are clamped in a shearing action, the gap between the shear blades is a key parameter of the transverse shear, and the gap between the shear blades is changed along with the thickness of a plate strip continuously, so that the transverse shear generally has an automatic or manual adjusting function of the gap to adapt to shearing requirements of different specifications. However, after a certain period of use, the gap between the cutting blades cannot be made uniform or unstable during cutting regardless of the adjustment of the gap between the cutting blades on the operating side and the driving side, which results in an unsuccessful cutting of the steel material. The unstable reason in clearance has a lot of, sometimes be the lathe warp, sometimes be the slide mechanism wearing and tearing, then need change lathe or slider in this kind of time, even whole main body frame can solve the unstable problem in clearance. The fundamental reason for the problem is that the slideway gap of the cross-cut shear is realized by the machining precision and the assembling precision of the equipment, and does not have the real-time adjustable function, and the stability of the slideway mechanism gap is realized by the regular maintenance and replacement of spare parts and regular calibration of the equipment.
In order to adjust the gap of the slideway conveniently, a method capable of adjusting the gap of the crosscut shear slideway in real time is provided, and mainly a set of mechanism capable of adjusting in real time is added.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a device in slide clearance is cut in adjustment crosscut to above-mentioned problem exactly.
The purpose of the utility model is realized like this: the utility model provides a device of slide clearance is cut in adjustment crosscut, includes, frame, upper slitter bed and cutting edge and lower slitter bed and cutting edge, still includes, slide, slider and adjustment backup pad, and the slider one side sets up on upper slitter bed and cutting edge, and the relative another side sets up on the slide, and the slide is fixed in the frame with the bolt, and the adjustment backup pad passes through the bolt fastening in the recess of frame.
Further, the bolt hole of the bolt is a long hole.
The utility model has the advantages that:
1) can effectively solve the problem of uneven gaps caused by the deformation of the cutter bed and the abrasion of the slide way.
2) The adjustment of the slide clearance can be carried out in real time, the adjustment efficiency is improved, and the time is shortened from more than 12 hours to about 1 hour.
3) The chute is separate from the frame, the chute section can be made of a better material and heat treated without fear of excessive cost, and is easily replaced.
4) The labor intensity is reduced, and the loss of spare parts is reduced.

Detailed Description
The following description is made with reference to the accompanying drawings:
firstly, a set of slide gap adjusting mechanism is added, the set of gap adjusting mechanism mainly comprises a slide 4 and an adjusting support plate 6, a slide block 5 is fixed on an upper cutter bed 2, and the upper cutter bed, a cutting edge 2 and the slide block 5 are lifted up and down along the slide during cutting (as shown in figures 2 and 3). The slider 5 adopts the copper slider, and slide 4 is fixed on frame 1 with the bolt, and the bolt hole is the slot hole to the regulation in clearance of being convenient for, slide 4 adopts wear-resisting steel to through heat treatment process, the surface hardness reaches more than HRC55, and for going up the cutting bed lift more smooth and easy, surface roughness reaches 0.8 as far as possible. The adjusting support plate 6 is also fixed in a groove of the frame through a bolt, so that the adjusting support plate can bear larger impact load and is more stable. When the gap of the slide way needs to be adjusted, the jackscrew on the adjusting support plate is adjusted to further push the slide way, so that the purpose of adjusting the gap is achieved. The clearance of the slide way can be conveniently and rapidly adjusted, and the consistency of the clearance of the shear blades can be finally ensured.
Wherein, the slide is a steel plate, and the size is 100 x 40 x 600 mm. The adjusting support plate is a steel plate with the size of 45 x 35 x 600mm, and the whole adjusting support plate is arranged in a groove of the rack. The groove is 1 through long groove. The sliders are copper sliders, 4 sliders in total, 40 × 26 × 350mm in size, and are welded at the middle upper part of the upper cutter bed.
The impact force F is mainly borne during the shearing process, and the force is mainly borne by the slideway and the adjusting support plate, so that the slideway and the adjusting support plate can bear enough impact force.
Firstly, the slideway is required to bear impact load, the load which can be borne by the slideway can be calculated by a formula, so that the strength and the number of bolts and the fixing mode can be better selected, and the stress of the slideway is shown in figure 3:
Fh=k1nμfkd
Fh= slideway bearable load k1= safety factor, n = number of bolts, μ = coefficient of friction, f = pretension, k = coefficient of tightening torque, d = bolt diameter.
In addition, the adjusting support plate also bears a part of load impact, if most of impact load is borne by the adjusting support plate after the slide way bolt is loosened, the adjusting support plate is installed in a groove of the rack at the position, so that a large part of impact load is borne by the rack, the impact load is not borne by only a bolt clamping force, the gap is enabled to be more stable, and the stress analysis of the adjusting support plate is shown in figure 4.
The bearable impact Fz = k of the adjusting support plate1nμfkd+σs*S*k2
Wherein σ S = yield strength of the frame material, S = contact area of the support plate and the frame, k2And = safety factor.
In addition, the securing loads of the fixing bolts and the jackscrews are checked to ensure that the impact load can be secured, which can be queried in the design manual.
After the adjusting mechanism is arranged, the deflection of the slide way gap machine can be adjusted in real time, and the jackscrew is continuously adjusted according to the detected numerical value until the required gap value is reached.
The method has the advantages that the adjustment can be carried out in real time, the operation is simple and convenient, the traditional method for carrying out machining compensation on the back cushion copper sheet or the spare parts when the slide gap is adjusted is changed, and the efficiency is very high. The method can be used not only on the slideway gap of the crosscut shears, but also on similar slideway mechanisms.
The cold-rolling transverse cutting device is used on transverse cutting of cold-rolling 8# longitudinal cutting, has good using effect, and effectively solves the problem that the gap between the operating side and the transmission side of the transverse cutting device is inconsistent.
Adjusting the installation mode and the structural form of the supporting plate and the slideway, and adjusting the reference position and the deflection amount of the slideway of the transverse cutting shear bed.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art can make changes or modifications within the scope of the present invention.
