Description

Pendulum cuts upper scissor blade front pressuring plate device
Technical field
The invention belongs to metallurgy rolling technical field, relate to a kind of pendulum and cut upper scissor blade front pressuring plate device.
Background technology
In metallurgical equipment, pendulum is cut and is sheared for horizontal hot shearing bloom and slab and other steel billets that is square and rectangular cross section, and its upper and lower two blades are parallel to each other, sometimes also for shearing the middle-size and small-size finished section bar under cold conditions.Its cut mode can be divided into up cut and lower cut two kinds.The feature of up cut parallel blade cutter is cut under being and is maintained static, and shearing rolled piece is that the motion of top cutting edge has come.This cutter structure is simple, lighter in weight.Major defect is rolled piece flexible, shearing area out of plumb when shearing, so that affects rolled piece trouble-free operation in orbit, compromises product quality, reduces production rate.
Summary of the invention
The object of this invention is to provide a kind of pendulum and cut upper scissor blade front pressuring plate device, solve prior art pendulum and cut and easily pile up when shearing rolled piece bending before upper scissor blade, run smooth, the ropy problem of shear plane.
The technical solution adopted in the present invention is, a kind of pendulum cuts upper scissor blade front pressuring plate device, in upper tool post bottom, sharp corner is provided with upper scissor blade, the up and down hanging deck of upper tool post top towards rolled piece approach axis has vertically coaxial through hole, two openings are along being respectively arranged with a sliding sleeve, and in these two through holes and sliding sleeve thereof, common slip is provided with a connecting rod; The openings of upper tool post upper surface is along being installed with protective cover; protective cover and sliding sleeve and connecting rod are coaxially arranged; protective cover upper end is fixedly connected with the cylinder body front end flange of hydraulic cylinder; the piston rod of hydraulic cylinder is connected with connecting rod downwards by flange sleeve, and connecting rod lower end is fixedly connected with pressing plate by panel nut.
Pendulum of the present invention cuts upper scissor blade front pressuring plate device, and its feature is also:
The high and low position of pressing plate is suitable with upper scissor blade, and the front end of pressing plate is duck-bill type structure.
This device has been arranged side by side two groups in rolled piece approach axis upper scissor blade front, and two groups of structures are identical, synchronous operation; Pressing plate is a monoblock, or two of same structure.
Beneficial effect of the present invention is: novel structure, and one is improve shearing quality, cuts rear section concordant, and steel plate flatness increases; Two is solve the problem needing to shut down after original rolled piece is piled up before cutting and dredge and make the operation of whole production line not smooth, decreases machine stop times, improves the rhythm of whole production line, thus improve product quality, add production efficiency.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the structure of apparatus of the present invention is, in upper tool post 4 bottom, sharp corner is provided with upper scissor blade 8, on the hanging deck up and down of rolled piece approach axis, vertically coaxial through hole is had on upper tool post 4 top, two openings are along being respectively arranged with a sliding sleeve 9, and in these two through holes and sliding sleeve 9 thereof, common slip is provided with a connecting rod 5; The openings of upper tool post 4 upper surface is along being installed with protective cover 2, protective cover 2 is coaxially arranged with sliding sleeve 9 and connecting rod 5, protective cover 2 upper end is fixedly connected with the cylinder body front end flange of hydraulic cylinder 1, the piston rod of hydraulic cylinder 1 is connected with connecting rod 5 downwards by flange sleeve 3, and connecting rod 5 lower end is fixedly connected with pressing plate 6 by panel nut 7;
The high and low position of pressing plate 6 is suitable with upper scissor blade 8, and the front end of pressing plate 6 is duck-bill type structure;
With reference to Fig. 2, the above-mentioned device of the present invention can be arranged side by side two groups in rolled piece approach axis upper scissor blade 8 front, and two groups of structures are identical, synchronous operation.Now, pressing plate 6 can be a monoblock, also can be two of same structure.
Operation principle of the present invention is,
Self front end flange of hydraulic cylinder 1 is connected with the protective cover 2 of hydraulic cylinder piston rod; hydraulic cylinder 1 piston rod is connected with connecting rod 5 by flange sleeve 3; protective cover 2 bottom is bolted on upper tool post 4; connecting rod 5 is connected with pressing plate 6 by panel nut 7; upper scissor blade 8 is fixed on upper tool post 4; thus whole presser device and upper scissor blade 8 have just been fixed on upper tool post 4 simultaneously, but pressing plate 6 can by hydraulic cylinder 1 relatively upper tool post 4 carry out the work lifting and press down.From Fig. 1, Fig. 2 sees, apparatus of the present invention are positioned at cutting edge front portion, when rolled piece is from traffic direction supplied materials, two hydraulic cylinder 1 piston rods are upheld simultaneously, pressing plate 6 is first depressed into the height the same with upper scissor blade 8, front end due to pressing plate 6 is easy to guide rolled piece to pass through, ensure that rolled piece can enter pendulum smoothly and cut, after then waiting rolled piece to run preseting length, rolled piece stops moving forward, pressing plate 6 again carries out pressing action by hydraulic cylinder 1 and compresses rolled piece, thus make it be fixed on before cutting edge, at this moment upper scissor blade 8 is undertaken pressing down and shearing by upper tool post 4, pressing plate 6 controls depression depths by hydraulic cylinder, and (pressing plate 6 is controlled by cylinder pressure, hydraulic cylinder body is fixed on knife rest, but hydraulic cylinder piston rod is contacted with upper tool post by self-lubricating cover, piston rod and pressing plate be can phase cutter setting frame and cutting edge up and down), shearing completes rear fender and is raised to origin-location and plays conduction band effect, it is exactly more than a working cycles of pressing plate.
In brief, on upper tool post 4, whole pressing plate apparatus of the present invention are installed in boring, upper tool post 4 carries out knee-action, and makes pressing plate 6 compress rolled piece by the up and down reciprocatingly action of hydraulic cylinder 1 to shear, unclamp pressing plate 6 again and make rolled piece smooth after having sheared by hydraulic cylinder 1.
The pendulum that contrast prior art does not install presser device is cut, and Duckbill type pressing plate can ensure that rolled piece enters pendulum smoothly and cuts, thus plays the effect of conduction band, avoids the problem that rolled piece is piled up before cutting edge; Pressing plate carries out pressing action by hydraulic cylinder and compresses rolled piece, and make it be fixed on before cutting edge, because rolled piece is fixed, so shear surface is straight, shearing quality significantly improves.
