Description
Technical Field
The utility model relates to a prosthetic devices, especially a scale cutting edge prosthetic devices belongs to the processing machinery field.
Background
In the production of the bar, in order to ensure the machine hour output, cold pendulum flying shears and fixed length flying shears are mostly adopted, see fig. 1-2, the existing flying shear cutting edge device consists of a flying shear cutting edge, a cutter holder and a bolt hole, the contact part of the cutting edge and the bar is easy to deform, break, fall and the like, the cutting blade is designed to cut the tonnage 2 ten thousand tons/time, along with the improvement of the quality requirement of a client on the bar, the cutting blade is cut the tonnage and reduced to the current 1 ten thousand tons-1.5 ten thousand tons/time, if the cutting blade is used for one time, the cost of the cutting blade is increased, the original cutting blade is also repaired, and a gasket mode is added at the bottom of the cutting blade after the repair, but the gasket is easy to loosen and fall in the cutting process, so that the cutting blade is abnormally. The main disadvantages of the shear blade device of this construction are: the consumption of spare parts of the cutting edge is large, the production line operation rate is low, and the production cost is high. In view of this, the repair method should be improved.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a change and make things convenient for the cold flying shear of scale, possess the scale cutting edge prosthetic devices of repeatedly restoreing and using to prolong its life, reduce the consumption of cutting edge spare part, improve the production line operating rate.
The technical scheme of the utility model is specifically as follows:
the utility model provides a scale cutting edge prosthetic devices, includes the blade holder, and the blade holder bottom is equipped with the blade holder keyway, treats prosthetic cutting edge bottom and is equipped with the forked tail keyway, and cutting edge bottom and blade holder bottom are equipped with the forked tail cushion, and the screw hole at cutting edge middle part is waist shape hole, and fastening bolt passes waist shape hole and fixes the cutting edge on the blade holder.
Further, the waist-shaped hole is not in contact with at least a part of the fastening bolt.
Further, the thickness of the cushion block is matched with the repairing size of the shear blade to be repaired.
Furthermore, the dovetail of the dovetail block is arranged in the center of the top, and the thickness of the dovetail block is 3-12 mm. Furthermore, one end of the fastening bolt is fixed on one side of the tool apron through a fastening nut.
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) adopt the utility model discloses a cold flying shear cutting edge prosthetic devices of scale, when the cutting edge restoration back, need the preparation have the cushion of dovetail key, the size is according to restoreing highly and surely, dovetail cushion repeatedly usable and non-deformable. The whole scrap of the whole shear blade device is avoided to the maximum extent, the spare part consumption is reduced, and the production cost is reduced. Has the characteristics of reliable performance, convenient replacement and the like.
(2) Use the utility model discloses afterwards, multiplicable 4~6 restoration times, reduce the consumption number of cutting edge spare part by a wide margin, ton steel consumption is reduced to 0.32 yuan/ton by original 0.76 yuan/ton. The problem that the gaskets are loosened and fall due to the fact that the quantity of the added gaskets is large is solved, so that the shearing blades are damaged abnormally, and batch elbow waste products are generated when the reinforcing steel bars are sheared.
(3) The waist-shaped hole can ensure that the shearing center line remains unchanged after the shearing edge is installed, and avoids the situation that the shearing edge is ground by pulling the steel bar due to the overhigh shearing edge after the shearing edge is repaired or the installation height of the shearing edge is too low and the overlapping amount is insufficient.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 3, the fixed-length shear blade repairing device of this embodiment includes blade holder 4, and blade holder 4 bottom is equipped with blade holder keyway 5, treats that prosthetic shear blade 1 bottom is equipped with forked tail keyway 6, and shear blade 1 bottom and blade holder 4 bottom are equipped with forked tail cushion 7, and the screw hole at shear blade 1 middle part is waist shape hole 8, and as shown in fig. 4, fastening bolt 2 passes waist shape hole 8 and fixes shear blade 1 on blade holder 4. One end of the fastening bolt 2 is fixed on one side of the tool apron 4 through a fastening nut 3.
As shown in fig. 3, the kidney-shaped hole 8 is not in contact with at least a part of the fastening bolt 2 at the upper end. The thickness of the cushion block 7 is matched with the repairing size of the shear blade to be repaired. The dovetail of the dovetail block 7 is arranged at the center of the top, and the thickness of the dovetail block 7 is 3-12 mm.
The device of the embodiment can be repeatedly repaired and used, and the repairing mode is as follows: the size of the end of the shear blade can be reduced by 3-5 mm when the shear blade is repaired each time, the height of a new blade is 180mm, the height of the blade can be repaired by 20mm at the lowest, and the repair can be repeated for 4-6 times, a dovetail key groove is machined at the bottom of the blade during repair, and then a gasket with a dovetail is installed at the bottom of the blade; the blade screw hole is processed into waist shape hole by the round hole, and cushion thickness is decided according to the restoration size, is convenient for install on the blade holder along with the increase of cushion thickness.
In this embodiment, the screw hole of the new shear blade is processed into a waist-shaped hole when being purchased, as shown in fig. 4. The new blade returns to a manufacturer for repairing after being used, and the cutting edge is ground after being quenched during repairing, and the hardness is guaranteed to be HRC 55-58. Processing a dovetail groove at the bottom of an old blade, manufacturing a batch of 3-12mm cushion blocks with dovetails, and using corresponding cushion blocks according to the repair quantity to ensure that the height of a repaired shear blade is consistent with that of a new shear blade.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
