The utility model provides a multiple length flies to cut rolled piece sampling device 10, please see fig. 1 to fig. 9, and this multiple length flies to cut rolled piece sampling device 10 includes flying shear mechanism 1 and goat mechanism 2. Specifically, the flying shear mechanism 1 has an upper tool rest 11 and a lower tool rest 12 which are oppositely arranged, the upper tool rest 11 and the lower tool rest 12 are respectively rotatably arranged, a sampling shear blade 111 and a multiple length shear blade 112 are respectively arranged on the upper tool rest 11 and the lower tool rest 12, and the sampling shear blade 111 and the multiple length shear blade 112 are arranged at intervals along the rotation circumferential direction of the upper tool rest 11 or the lower tool rest 12. The switch mechanism 2 is arranged on one side of the flying shear mechanism 1, the switch mechanism 2 has an inlet duct 21 which can transport the profile 100 between the upper tool holder 11 and the lower tool holder 12, and the inlet duct 21 is arranged to be able to oscillate back and forth between a rolling position and a sampling position.

In the sampling device 10 for the multiple-length flying shear rolled piece, the inlet guide pipe 21 on the switch mechanism 2 is switched between the rolling position and the sampling position, so that the rolling function (namely, multiple-length shearing) of the profile 100 and the sampling function of the profile 100 can be realized, and a sample section 102 which really reflects the quality of the profile 100 can be obtained in the sampling process; meanwhile, rolling (namely, multi-length shearing) and sampling of the section bar 100 do not need to be carried out manually, so that the labor intensity of a human body is reduced, and the safety and the shearing precision of the human body are ensured.

In order to enable the sampling device 10 for the double-length flying shear to normally realize the functions of rolling (namely double-length shearing) and sampling, the double-length cutting edge 112 and the sampling cutting edge 111 arranged on the upper tool rest 11 and the lower tool rest 12 are provided with the cutting edges of a conventional double-length flying shear mechanism.

Specifically, the double length cutting edge 112 and the sampling cutting edge 111 are configured as shown in fig. 1 and 10, the arrangement direction F4 of the double length cutting edge 112 (or the sampling cutting edge 111) is perpendicular to the central axis of the upper tool rest 11 or the central axis of the lower tool rest 12, and the double length cutting edge 112 and the sampling cutting edge 111 are arranged on the outer surface of the upper tool rest 11 or the lower tool rest 12. Wherein the included angle θ between the shearing surface a of the double length cutting edge 112 (or the shearing surface a of the sampling cutting edge 111) and the rotating direction F1 of the upper tool holder 11 is 20 ° to 40 °, and in some preferred embodiments is 30 °; similarly, the angle θ between the cutting plane a of the double length cutting edge 112 (or the cutting plane a of the sampling cutting edge 111) and the direction of rotation F2 of the lower blade holder 12 is also 20 ° to 40 °, and in some preferred embodiments 30 °. That is, the arrangement direction F4 of the multiple length cutting edge 112 (or the sampling cutting edge 111) and the shearing plane a of the multiple length cutting edge 112 (or the shearing plane a of the sampling cutting edge 111) form a first included angle θ 1, and the first included angle θ 1 is 50 ° to 70 °, and in some preferred embodiments, the first included angle θ 1 is 30 °. In addition, a second included angle θ 2 is formed between the bottom surface of the double length cutting edge 112 (or the sampling cutting edge 111) and the inclined surface B of the double length cutting edge 112 (or the inclined surface B of the sampling cutting edge 111), and the second included angle θ 2 is 50 ° to 80 °, and in some preferred embodiments, the second included angle θ 2 is 80 °, please refer to fig. 10.

It should be understood by those skilled in the art that the included angle θ between the shearing plane a of the double length cutting edge 112 (or the shearing plane a of the sampling cutting edge 111) and the rotating direction F1 of the upper tool rest 11, and the included angle θ between the shearing plane a of the sampling cutting edge 111 and the rotating direction F1 of the upper tool rest 11 may also be different, as long as the double length cutting edges 112 on the upper tool rest 11 and the lower tool rest 12 can cooperate with the rolling of the finished product 100 (i.e., double length cutting), and the sampling cutting edges 111 on the upper tool rest 11 and the lower tool rest 12 can cooperate with the sampling of the finished product 100, which should be within the protection scope of the present invention.

The working process of the multiple-length flying shear rolled piece sampling device 10 is as follows:

referring to fig. 1 and 2, in the rolled condition, the switching mechanism 2 transports the profile 100 between the upper tool holder 11 and the lower tool holder 12 through the inlet duct 21. At this time, the upper tool rest 11 has a rotation direction F1, the lower tool rest 12 has a rotation direction F2, and the upper tool rest 11 and the lower tool rest 12 rotate along the respective rotation shafts 232. When the double-length cutting edge 112 on the upper tool rest 11 and the double-length cutting edge 112 on the lower tool rest 12 rotate to preset positions, the profile 100 can be rolled (namely, double-length shearing), as the profile 100 is continuously fed along the transportation direction F3, the upper tool rest 11 and the lower tool rest 12 continuously rotate along the respective rotating shafts 232, the double-length cutting edge 112 on the upper tool rest 11 and the double-length cutting edge 112 on the lower tool rest 12 can continuously roll (namely, double-length shearing) the profile 100, so that the rolling stock 100 is continuously rolled (namely, double-length shearing) through the double-length flying shear sampling device 10, and a plurality of rolled sections 103 of the profile 100 with the double-length are obtained.

Those skilled in the art will appreciate that the direction of rotation F1 of the upper tool holder 11 and the direction of rotation F2 of the lower tool holder 12 are opposite, but both rotate towards one side of the switch mechanism 2, i.e. in some embodiments the direction of rotation F1 of the upper tool holder 11 is clockwise and the direction of rotation F2 of the lower tool holder 12 is counter-clockwise; in other embodiments, as shown in FIG. 1, the direction of rotation F1 of upper tool holder 11 is counter-clockwise and the direction of rotation F2 of lower tool holder 12 is clockwise. Of course, it should be understood by those skilled in the art that the rolling (i.e. multiple-length cutting) length of the profile 100 is determined by the circumference of the upper tool holder 11 and the circumference of the lower tool holder 12, and the user can select the upper tool holder 11 and the lower tool holder 12 with suitable circumferences according to his/her needs, and then can cut the profile 100 according to the preset multiple-length to obtain the rolling section 103 of the profile 100 with a specific multiple-length.

When it is desired to sample the profile 100, see fig. 2, 5 and 6, the inlet duct 21 is swung from the rolling position to the sampling position, i.e. the centre line of the inlet duct 21 in the rolling position and the centre line of the inlet duct 21 in the sampling position form a swing angle a. In one embodiment, the angle of oscillation of the inlet duct 21 is less than 5 °. More specifically, in some embodiments, the swing angle α is 3 ° to 4 °.

In this state, the switching mechanism 2 transports the profile 100 between the upper tool holder 11 and the lower tool holder 12 through the inlet duct 21. At this time, the upper tool rest 11 has a rotation direction F1, the lower tool rest 12 has a rotation direction F2, and the upper tool rest 11 and the lower tool rest 12 rotate along the respective rotation shafts 232. When the double-length cutting edge 112 on the upper tool rest 11 and the double-length cutting edge 112 on the lower tool rest 12 rotate to preset positions, the profile 100 can be cut for the first time, and the waste section 101 (in some embodiments, the waste section 101 is the head section of the profile 100) of the profile 100 is obtained, as the profile 100 is continuously fed along the transportation direction F3, the upper tool rest 11 and the lower tool rest 12 continue to rotate along the respective rotating shafts 232, the sampling cutting edge 111 on the upper tool rest 11 and the sampling cutting edge 111 on the lower tool rest 12 rotate to another preset position and cut the profile 100 for the second time, so that the sampling cutting of the profile 100 is completed through the double-length flying-cut rolled piece sampling device 10, and the sample section 102 of the profile 100 is obtained. Because the first shearing of the profile 100 can remove the waste section 101 of the profile 100, the sample section 102 obtained after the second shearing of the profile 100 better meets the sampling standard, and the sample section 102 can better represent the quality of the profile 100.

It will be appreciated by those skilled in the art that the length of the sample section 102 of the profile 100 is determined by the position of the double length cutting edge 112 and the sampling cutting edge 111 on the upper tool holder 11 and the lower tool holder 12, i.e. by the degree of the central angle β formed by the apexes of the double length cutting edge 112 and the sampling cutting edge 111 on the rotary shaft 232 of the upper tool holder 11 or the lower tool holder 12. The user can adjust the degree of the central angle β according to the needs of the user, so as to obtain the sample segment 102 of the profile 100 with a specific length, and further perform subsequent sample analysis. In various embodiments, the center angle β may be an integer multiple of 5 °, such as 5 °, 10 °, 15 °, 20 °, and so on.

After the sampling operation of the profile 100 is completed, referring to fig. 7, the inlet duct 21 swings back from the sampling position to the rolling position to continue rolling the profile 100 (i.e., double-length shearing), i.e., after the inlet duct 21 swings back by the angle α, it returns to the initial position and continuously rolls the profile 100 (i.e., double-length shearing).

Therefore, the sampling device 10 for the multiple-length flying shear rolled piece can be switched between a rolling position and a sampling position, so that the function of rolling (namely multiple-length shearing) the profile 100 and the function of sampling the profile 100 can be realized, and a sample section 102 which truly reflects the quality of the profile 100 can be obtained during sampling; meanwhile, rolling (namely multi-length shearing) and sampling are not required to be carried out manually, so that the labor intensity of a human body is reduced, and the safety and the shearing precision of the human body are ensured.

In some embodiments, referring to fig. 8 and 9, the switch mechanism 2 comprises a foundation 22, an inlet duct 21 and a jacket 23. Specifically, the jacket 23 is used for fixing the inlet duct 21, one end of the jacket 23 is connected to the base 22 in a horizontally rotatable manner, the other end of the jacket 23 is connected to the driving mechanism 3, and the jacket 23 is arranged on the base 22 in a horizontally swingable manner through the driving mechanism 3.

In this embodiment, the driving mechanism 3 can drive the jacket 23 to rotate on the base 22 by a predetermined angle (i.e. the swing angle α of the inlet duct 21) in the horizontal direction, and because the jacket 23 is fixedly connected to the inlet duct 21, the inlet duct 21 can also swing by a predetermined angle (i.e. the swing angle α of the inlet duct 21) as the jacket 23 rotates, i.e. the inlet duct 21 swings from the rolling position to the sampling position. When it is desired to swing the inlet conduit 21 from the sampling position to the rolling position, this is achieved by driving the jacket 23 on the base 22 in the opposite direction by means of the driving mechanism 3.

It will be appreciated by those skilled in the art that in order to ensure that the inlet duct 21 can oscillate back and forth between the rolling position and the sampling position, in some embodiments the drive mechanism 3 further comprises a connecting rod 31, the two ends of the connecting rod 31 being connected to the drive motor and the jacket 23, respectively. Of course, in some embodiments, the driving mechanism 3 further comprises a controller for precisely controlling the magnitude of the driving force, so as to ensure that the rotation angle of the jacket 23, and thus the swing angle α of the inlet duct 21, is the same.

In some embodiments, referring to fig. 8 and 9, the base 22 of the switch mechanism 2 is provided with a sliding slot 221, the other end of the jacket 23 is connected with a pin 231, and the pin 231 is reciprocally disposed in the sliding slot 221. The utility model discloses in, spout 221 on the base 22 can cooperate with the round pin axle 231 of being connected on the jacket 23, realizes round pin axle 231 reciprocating motion in spout 221, actuating mechanism 3 is at the in-process of drive jacket 23 reciprocating motion promptly, leads and spacing through spout 221 to the motion of jacket 23 to guarantee that the inlet pipe 21 that links to each other with jacket 23 can predetermine the angle (follow horizontal direction swing angle alpha promptly) according to predetermineeing the direction swing.

In some embodiments, referring to fig. 8 and 9, one end of the jacket 23 of the switch mechanism 2 is connected to the rotating shaft 232, the base 22 is provided with a connecting hole 222, and the rotating shaft 232 is sleeved with the bearing 2321 and is rotatably disposed in the connecting hole 222 through the bearing 2321. The utility model discloses a pivot 232 has injectd the rotation center of jacket 23 (having injectd the swing center of entry pipe 21 promptly) of being connected with pivot 232 with the cooperation of connecting hole 222 to avoid the collision and the contact of other parts in entry pipe 21 and the goat mechanism 2, further guaranteed the holistic structural strength of equipment. In addition, through increasing bearing 2321 between pivot 232 and connecting hole 222, reduced pivot 232 friction in the rotation process to reduce the wearing and tearing of pivot 232, avoided frequent change pivot 232, further reduced the cost of maintenance of product, improved market competition.

In some embodiments, referring to fig. 1 and 2, the double length cutting edge 112 and the sampling cutting edge 111 of the upper tool holder 11 are both connected to the outer surface of the upper tool holder 11 in a direction parallel to the rotation axis 232 of the upper tool holder 11, and the double length cutting edge 112 and the sampling cutting edge 111 of the lower tool holder 12 are both connected to the outer surface of the lower tool holder 12 in a direction parallel to the rotation axis 232 of the lower tool holder 12, wherein the rotation axis 232 of the upper tool holder 11 is parallel to the rotation axis 232 of the lower tool holder 12.

By adopting the design, on one hand, the bending moment and the torque can be prevented from being respectively caused to the upper tool rest 11 and the lower tool rest 12 when the double-length shear blade 112 and the sampling shear blade 111 respectively shear the section bar 100, so that the stress direction is more uniform and stable, and the structural strength of the upper tool rest 11 and the lower tool rest 12 is further ensured; on the other hand, the shear planes of the sample segment 102 of the profile 100 can be guaranteed to be the same, and further machining of the shear planes is not needed.

In one embodiment, referring to fig. 2, 5, 6 and 7, a portion of double length cutting edge 112 coincides with sampling cutting edge 111 in the direction of rotation of upper blade holder 11 or lower blade holder 12. In some embodiments, the length of the double length cutting edge 112 is greater than the length of the sampling cutting edge 111, and the length of the coincidence of the double length cutting edge 112 and the sampling cutting edge 111 is equal to the length of the sampling cutting edge 111. In other embodiments, the length of the double length cutting edge 112 is equal to the length of the sampling cutting edge 111, and the double length cutting edge 112 and the sampling cutting edge 111 have coinciding lengths in the rotation direction of the upper tool holder 11 or the lower tool holder 12, wherein the double length cutting edge 112 and the sampling cutting edge 111 are arranged in a staggered manner (i.e., the double length cutting edge 112 and the sampling cutting edge 111 do not coincide completely).

It should be understood by those skilled in the art that the coincidence of the double-length cutting edge 112 and the sampling cutting edge 111 is to cut off the waste segment 101 of the profile 100 by the double-length cutting edge 112 and then cut off the sample segment 102 of the profile 100 by the sampling cutting edge 111 during the sampling process of the profile 100; during the rolling (i.e., multiple shearing) of the profile 100, only the multiple shearing blade 112 is able to roll (i.e., multiple shearing) the profile 100. That is, in the state in which the inlet duct 21 is in the rolled position, the profile 100 can only be sheared by the double length cutting edge 112; in the state of the inlet duct 21 in the sampling position, the profile 100 can be cut by the double-length cutting blade 112 to cut the waste segment 101 thereof, and then the sampling cutting blade 111 is used to cut the sample segment 102 of the profile 100. Therefore, it is within the scope of the present invention that the double length cutting edge 112 and the sampling cutting edge 111 partially overlap when viewed in the rotation direction of the upper tool holder 11 or the lower tool holder 12.

The rolling channel 41 and the sampling channel 42 are arranged side by side, so that the rolling position corresponds to the rolling channel 41 and the sampling position corresponds to the sampling channel 42 only by horizontally swinging the inlet guide pipe 21 between the rolling position and the sampling position; therefore, the jacket 23 is not required to be provided with a structure capable of moving along the gravity direction, the structural complexity of the switch mechanism 2 is further reduced, and the production cost of the sampling device 10 for flying and shearing rolled pieces by multiple scales is improved.

In some embodiments, referring to fig. 3 and 4, the transport bottom 411 of the rolling channel 41 is arranged horizontally and the transport bottom 421 of the sampling channel 42 is arranged obliquely downwards in the transport direction. The utility model discloses a this kind of design can utilize the transportation bottom surface 421 that sampling channel 42 slope set up, obtains the sample section 102 of section bar 100 fast to be convenient for to the later stage analysis of sample section 102. It will be understood by those skilled in the art that the transport base 411 of the rolling channel 41 may also be arranged inclined downwards in the transport direction F3 in order to bring the rolled section 103 of multiple length obtained by rolling (i.e. multiple shearing) into the subsequent process step quickly.

In some embodiments, referring to fig. 3 and 4, the rolling channel 41 is horizontally opposite the rolling position of the inlet duct 21 and the sampling channel 42 is horizontally opposite the sampling position of the inlet duct 21. The utility model discloses a this kind of design only needs entry pipe 21 horizontal hunting between rolling position and sampling position just to enable rolling position and rolling passageway 41 corresponding, and sampling position is corresponding with sampling passageway 42. That is, by using the design, on one hand, the rolling channel 41 can be provided for the rolling section 103 obtained by rolling (i.e. cutting) the profile 100 by the multiple length cutting edge 112, so that the rolling sections 103 are collected and gathered, and further, the subsequent processes are facilitated; on the other hand, the waste section 101 and the sample section 102 of the profile 100 cut by the flying shear mechanism 1 can be collected and gathered in the sampling channel 42, so that the subsequent processes can be conveniently carried out.
