As is well known, in the process of manufacturing medium and heavy plates, shearing of medium and heavy plates is an extremely important process step, and the existing shearing equipment mainly comprises a bevel-edge shearing machine and a hobbing type shear mill. The existing oblique-blade shearing machine has the defects of rough and uneven cut, low shearing efficiency and the like, and can not meet the requirements of a rolling mill on the quality, variety and yield of medium-thickness steel plates. Thus, miter shears have gradually been replaced by hobbing shear-length shears. The utility model discloses a chinese utility model patent (patent number is 02203540.0) just discloses a roll-cutting formula scale cuts unit, including frame, top rest, lower knife rest, panel, blade clearance adjusting device and scale machine etc. be equipped with the swing track in the frame lower part, when the steel sheet was cuted, the swing track held the steel sheet luffing motion, had effectively improved the shearing quality. However, the existing hobbing type shear for sizing also has the following defects:
1. because the frame is the main atress part, and traditional "C" type frame is mostly adopted to current shear to length frame, because "C" type frame is not enough its rigidity under the big condition of atress, the frame vibrations are great when shearing, has directly influenced the cutting edge clearance to influence shearing quality.
2. The swing roller way is an indispensable important part in the shear-sizing machine, the structural form of the swing roller way at home and abroad at present mainly adopts centralized transmission, and the action modes of the swing roller way at home and abroad comprise a pre-swing type and an over-balanced type.

3. The shear blade clearance adjusting mechanism of the existing hobbing type shear is electrically controlled, the detection means also detects through an electric element, although the automation degree is higher, the clearance value of an upper tool rest and a lower tool rest can be changed into a negative value due to the fact that the electric element is frequently influenced by the surrounding environment and further generates failure, and therefore mutual shearing accidents of the upper shear blade and the lower shear blade occur.
4. The upper tool rest is a main part used for shearing of the fixed-length shearing machine and is a main stress part for realizing rolling shearing. The transmission is that an eccentric shaft drives a connecting rod to drive an upper tool rest to cut. The lubrication of the transmission part of the upper tool rest is an important condition for ensuring the normal work of the upper tool rest, the lubrication of the transmission part of the upper tool rest is realized by dry oil lubrication, although the structure is simple, the lubrication effect is poor, and as the dry oil lubrication is not provided with an oil return system, the waste dry oil needs to be cleaned regularly, so that the time and the labor are wasted, and the steel plate is easy to pollute.

The swing driving mechanism 93 is connected to the middle of the bottom side of the roller way frame 91 and used for driving the roller way frame 91 to swing, the swing driving mechanism 93 comprises two bending arms 931 and two swing driving hydraulic cylinders 932 which are arranged in parallel and symmetrically, the bending parts of the two bending arms 931 are pivoted through a rotating shaft 933, one end of each bending arm 931 is pivoted with the bottom side of the roller way frame 91, the other end of each bending arm 931 is connected with the telescopic end of the corresponding swing driving hydraulic cylinder 932, and the two bending arms 931 synchronously swing around the rotating shaft 933 in a reciprocating manner under the driving of the two swing driving hydraulic cylinders 932; the translation driving mechanism 94 comprises two translation driving hydraulic cylinders 941 which are symmetrically arranged in parallel, the telescopic ends of the translation driving hydraulic cylinders 941 are connected with the bottom side of the roller way frame 91, the translation driving hydraulic cylinders drive the roller way frame 91 to move along the axial direction (namely parallel to the moving translation direction of a sheared steel plate), the roller way frame can move, a first roller (an inert roller 921) of the swing roller way mechanism can be close to a shearing edge as far as possible during shearing, the minimum distance of the first roller can be 32mm, and therefore bending stress of the steel plate on a shearing section due to dead weight can be reduced, and shearing quality is improved.
When the over-balance type swing roller way mechanism 9 works, the over-balance type swing roller way mechanism 9 is under an over-balance force, the swing roller way mechanism 9 supports a steel plate in advance, when the upper tool rest 2 shears, the steel plate is extruded and sheared downwards, therefore, the upper tool rest 2 can give a downward force to the steel plate, the force is much larger than the over-balance force, at the moment, the swing roller way mechanism 9 can swing downwards under the action of the shearing force, an overflow valve is arranged in a hydraulic system of a swing driving hydraulic cylinder 932, the force generated by the pressure of the overflow valve is 1.2 times of the sum of the self weight of the swing roller way mechanism 9 and the self weight of the steel plate (namely, the over-balance coefficient is 1.2), and therefore the swing roller way mechanism 9 can swing. Because the upper blade 21 transmits the vertical motion to the swing roller way mechanism 9 through the steel plate, the swing roller way mechanism 9 can follow the upper blade 21, and the working efficiency is improved.
Further, a pressing plate 95 is covered on the end of the roller bed frame 91 close to the lower blade 31 of the lower blade holder 3. Thus, when the upper blade 21 shears downwards, the shearing force is transmitted to the pressing plate 95 through the steel plate and then transmitted to the swing roller way mechanism 9 to move, and the pressing plate 95 plays a role in protecting the steel plate and the swing roller way mechanism 9.
Further, as shown in fig. 7 and 8, an oil chamber 22 is formed in the upper tool rest 2, a gap is formed between a connecting rod 23 arranged on the upper tool rest 2 and the upper tool rest, the oil chamber 23 is communicated with the gap 25, a return pipeline 24 is formed at the lower part of the upper tool rest 2, and the return pipeline 24 is communicated with the lower part of the oil chamber 23 and extends to the outside of the upper tool rest 2. Thus, the gap 25, the oil chamber 23, and the return line 24 are communicated in sequence to form a return passage. The oil cavity 23 is formed in the upper tool rest 2, so that the weight of the upper tool rest 2 can be reduced, the shearing quality can be improved, thin oil generated when the upper tool rest 2 is lubricated can be contained in the oil cavity 23, and the oil quality can be prevented from being influenced by the pollution of the thin oil. And an oil return pipeline 24 at the bottom of the upper tool rest 2 can output the thin oil in the oil cavity 23 so as to realize recycling.
Further, as shown in fig. 8, the gap 25 is sealed by a grease seal. Thus, thin oil can be guided into the oil cavity 23 of the upper tool rest through the oil palace, and the lubricating effect of the thin oil is obviously higher than that of dry oil.
Further, as shown in fig. 1, the sizing machine 6 includes a sizing trolley 61 and a sizing rail 62, the sizing trolley 61 slides along the sizing rail 62, and an encoder for accurately calculating the sizing length is provided on the sizing machine 6. The sizing precision can not be influenced by the sizing length, so that the sizing is reliably and stably carried out, and the product quality and the yield are improved.
In conclusion, the whole machine frame has small stress deformation during shearing, the opening degree of the shearing blades and the stability of the gap value of the shearing blades are ensured, the flexibility of moving parts is ensured by good lubricating effect, the service life of parts is prolonged, the deformation of a steel plate during shearing is reduced by the over-balanced type swing roller way, the equipment is protected, and the shearing quality is improved. The invention realizes the beneficial effects of good shearing quality, high shearing precision, strong shearing capability, high shearing efficiency, smooth cut section of the product and the like.
