Specific implementation mode

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

A kind of arcwall face cutting mechanism, including ontology 1 and propulsive mechanism 2；The ontology 1 is provided with for carrying arcwall face The through-hole 11 that workpiece A is penetrated；The inner circumferential of the through-hole 11 is provided with cambered blade, for cutting the workpiece A；The curved knife Piece is moved with the movement of the ontology 1；The propulsive mechanism 2 is for shifting the workpiece A in the through-hole 11 onto.

Arcwall face workpiece A is generally cylindrical, and the diameter of through-hole 11 is suitable with the diameter of arcwall face workpiece A.The arc Blade（It is not shown in figure）Cut end shape and the peripheral shape of workpiece A mutually agree with.When being cut, propulsive mechanism 2 workpiece A are promoted in through-hole 11, and external mechanical exerts a force to cutting mechanism, compresses the ontology 1, the cambered blade is with described The movement of ontology 1 and move, to cut the workpiece A.

In some embodiments, the ontology 1 divides for top 13 and lower part 14；The top 13 is provided with cavity；Institute It states lower part 14 and is provided with lower cavity 141；The upper cavity and the lower cavity 141 are semi-circular cavities, and the two is opposite to be merged After form the through-hole 11.

The upper cavity（It is not shown in figure, position is corresponding with the lower cavity 141, size and the lower cavity 141 It is identical）Through-hole 11 is formd with the lower cavity 141, coats the workpiece A, top 13 and the lower part 14 generally connect with machine It connects, is finished when workpiece A is cut, top 13 and the lower part 14 are pulled open in machine driving, take out workpiece A at this time.

In some embodiments, it further illustrates, the cambered blade includes the first blade and the second blade 122, difference It is relatively arranged in the upper cavity and the lower cavity 141.

First blade（It is not shown in figure, position is corresponding with second blade 122, size and described second Blade 122 is identical）It is moved respectively with the top 13 and the lower part 14 with second blade 122, squeezes apply from outside to inside Power cuts the flower pattern workpiece A.

In some embodiments, it further illustrates, the ontology 1 further includes lower cover 16, and second blade 122 fixes peace Loaded under the lower cover 16；The lower cavity 141 is provided with lower groove 1411, and second blade 122 passes through the lower groove 1411；The relatively described lower cover 16 in the lower part 14 moves, and second blade 122 is made to protrude or be retracted the lower groove 1411.

When machine exerts a force to the upper and lower surface of arcwall face cutting mechanism, lower cover 16 drives second blade 122 upward It pushes away, the position cut force is needed to workpiece A, is cut off, and flexible mechanism between the lower cavity 141 and the lower cover 16, Ensure that the lower cavity 141 is coated on the outside of workpiece A without squeezing workpiece A, to keep the circular shape of workpiece A always.

In some embodiments, the ontology 1 further includes upper cover 15, and first blade is fixedly installed in the upper cover 15 On；The upper cavity is provided with upper groove, and first blade passes through the upper groove；The upper cover 15 relatively of the top 13 Movement keeps first blade prominent or the retraction upper groove.

When machine exerts a force to the upper and lower surface of arcwall face cutting mechanism, upper cover 15 drives first blade in upper groove （It is not shown in figure, position is corresponding with the lower groove 1411, and size is identical as the lower groove 1411）Interior movement and to It pushes, the position cut force is needed to workpiece A, is cut off, and flexible mechanism between the upper cavity and the upper cover 15, really It protects the upper cavity and is coated on the outside of workpiece A always without squeezing workpiece A, to keep the circular shape of workpiece A.Its principle Consistent with the incision principle of the second blade, the two cuts into two sections from upper and lower surface collective effect, workpiece A.

In some embodiments, the propulsive mechanism 2 includes cylinder 21 and promotion column 22；The cylinder 21 drives described push away Dynamic column 22 is moved along the axial direction of the through-hole 11.

The diameter of column 22 is pushed to be not more than the through-hole 11, so that it is guaranteed that workpiece A can be pushed into the through-hole 11.Institute It is that the promotion column 21 provides power to state cylinder 21, and the promotion column 22 is driven to stretch out or retract.

In some embodiments, it further illustrates, the propulsive mechanism 2 further includes limiting plate 23；The limiting plate 23 is set It sets in the front end for pushing column 22；The outer perimeter of the limiting plate 23 is more than the perimeter of the through-hole 11.

In order to allow specified positions of the workpiece A in through-hole 11 to stop, set close to the front position for pushing column 22 It is equipped with limiting plate 23；The outer perimeter of the limiting plate 23 is more than the perimeter of the through-hole 11, to make the promotion column 22 to institute When stating promotion in through-hole 11, limiting plate 23 can be against outside the through-hole 11, it is ensured that cambered blade can cut the fixation of workpiece A Position.The installation site of limiting plate 23 needs the position cut according to workpiece A and is set in advance in the depth of the through-hole 11 It is fixed.

In some embodiments, it further illustrates, the propulsive mechanism 2 further includes fixed plate 24, and the fixed plate 24 is used In the fixation cylinder 21.

The fixed plate 24 can keep cylinder 21 and the stability for pushing column 22.

In some embodiments, the top 13 and lower part 14 are respectively arranged with a pair of of sleeve 132 and a pair of posts 142； The sleeve 132 is socketed on the pillar 142.

The top 13 and the lower part 14 need to be aligned, and can be only achieved the purpose accurately cut to workpiece A.Therefore, exist Sleeve 132 is respectively set in the both sides on the top 13, and pillar 142 is respectively set in the both sides of the lower part 14, makes by socket Upper and lower two alignments, can also play the role of guiding and buffering in machine compression process.

The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as Limitations of the present invention, therefore the scope of protection of the utility model is subject to the range that claim defines.
