Description

Technical Field

[0001] The invention relates to the technical field of numerical control machine tool design, and in particular to a two-in-one mechanism for micro-tension and tail material feeding and a steel sheet shearing device. Background Art

[0002] At present, CNC machine tools are only equipped with one feeding device, and it is arranged in front of the shearing group. For steel sheets with narrow width and thin thickness, since the feeding device is arranged at the front of the machine tool, the distance between it and the shearing group is too long, which easily causes excessive scrap and waste of materials; in addition, during the transportation process, the steel sheet is prone to offset, distortion or arching between the feeding device and the shearing group, affecting the accuracy of stamping and shearing, and even hindering the normal operation of feeding. Therefore, how to overcome the above-mentioned defects in the long-distance transportation of steel sheets is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0008] The micro-tension conveying group comprises a first guide rail fixedly mounted on a movable slider, a first slider is movably mounted on the first guide rail, a first support frame is fixedly mounted on the first slider, and a conveying wheel is rotatably mounted in the first support frame;

[0010] A micro-tension and tail material feeding mechanism according to an embodiment of the present invention has at least the following beneficial effects: the micro-tension conveying group conveys the material under the drive of the lower transmission wheel group. Since the micro-tension conveying group rotates at a relatively fast speed during the conveying process, it has a pulling effect on the material during high-speed shearing, thereby preventing the material from bending and clogging in the channel, and has a good conveying effect during high-speed shearing and ultra-thin material shearing. When the tail material feeding transmission group is working, it plays a role of secondary conveying, which is used for tail material conveying, shortens the length of the tail material, and reduces waste.

[0011] According to some embodiments of the present invention, the motor is a servo motor.

[0012] According to some embodiments of the present invention, a lower transmission wheel bracket is provided on the bracket, and the lower transmission wheel is rotatably installed in the lower transmission wheel bracket.

[0013] According to some embodiments of the present invention, a first cylinder for controlling the first slider to move along the first guide rail is installed on the movable slider.

[0014] According to some embodiments of the present invention, a second cylinder for controlling the second slider to move along the second guide rail is installed on the movable slider.

[0015] According to some embodiments of the present invention, the length of the upper transmission wheel is the same as the length of the lower transmission wheel.

[0016] According to some embodiments of the present invention, the length of the conveying wheel is shorter than the length of the lower transmission wheel.

[0017] According to a second aspect of an embodiment of the present invention, a steel sheet shearing device comprises a frame, on which are provided a feeding assembly, a shearing assembly and the above-mentioned micro-tension and tail feeding mechanism, wherein the micro-tension and tail feeding mechanism is located between the feeding assembly and the shearing assembly.

[0018] A steel sheet shearing device according to an embodiment of the present invention has at least the following beneficial effects: since the micro-tension and tail material feeding mechanism is located between the feeding component and the shearing component; when the micro-tension conveying group conveys the material under the drive of the lower transmission wheel group, since the rotation speed of the micro-tension conveying group is faster than that of the feeding component during the conveying process, the material is pulled during high-speed shearing to avoid bending and clogging of the material in the channel, and it plays a good conveying role in high-speed shearing and ultra-thin material shearing; when the tail material feeding transmission group is working, the distance between the feeding component and the shearing component is shortened, playing the role of secondary conveying, which is used for tail material conveying, shortening the tail material length, reducing waste, and improving the shearing accuracy.

[0019] According to some embodiments of the present invention, the rotation speed of the lower transmission wheel is faster than the rotation speed of the feeding assembly.

[0020] According to some embodiments of the present invention, a discharging assembly is further disposed behind the shearing assembly.

[0030] Reference Figure 2 , Figure 3 A micro-tension and tail material feeding mechanism comprises a bracket 1 on which a lower transmission wheel set 2 and an upper transmission wheel set 3 are arranged.

[0031] Reference Figure 4The lower transmission wheel assembly 2 includes a lower transmission wheel 22 driven to rotate by a motor 21. In this embodiment, the motor 21 is a servo motor, which can adjust the rotation speed of the lower transmission wheel 22 according to actual needs. In addition, in order to facilitate the installation of the lower transmission wheel 22, a lower transmission wheel bracket 23 is provided on the bracket 1, and the lower transmission wheel 22 can be rotatably installed in the lower transmission wheel bracket 23.

[0032] Reference Figure 5 The upper transmission wheel group 3 includes a transverse guide rail 11 arranged on the bracket 1, and a movable slider 12 is arranged on the transverse guide rail 11. The movable slider 12 is pulled by the cylinder 31 to move left and right on the transverse guide rail 11. A micro-tension conveying group 4 and a tail material transmission group 5 are slidably installed on the movable slider 12;

[0033] In this embodiment, the micro-tension conveying group 4 includes a first guide rail 41 fixedly mounted on a movable slider 12, a first slider 42 movably mounted on the first guide rail 41, a first support frame 43 fixedly mounted on the first slider 42, and a conveying wheel 44 rotatably mounted in the first support frame 43; for unused materials, in order to facilitate the adjustment of the gap between the conveying wheel 44 and the lower transmission wheel 22, a first cylinder 45 for controlling the movement of the first slider 42 along the first guide rail 41 is installed on the movable slider 12. Since the conveying wheel 44 mainly plays a pulling role on the material, the length of the conveying wheel 44 can be shorter than the length of the lower transmission wheel 22 during production.

[0034] In this embodiment, the tail material transmission group 5 includes a second guide rail 51 fixedly mounted on the movable slider 12, a second slider 52 movably mounted on the second guide rail 51, a second support frame 53 fixedly mounted on the second slider 52, and an upper transmission wheel 54 rotatably mounted in the second support frame 53.

[0036] In order to pull the material and avoid bending and clogging of the material in the channel, the speed of the lower transmission wheel 22 is faster than that of the feeding assembly 7. In addition, a discharging assembly is also provided behind the shearing assembly 8, and the sheared steel sheet is automatically output by the discharging assembly.

[0037] Because the micro-tension and tail material feeding mechanism is located between the feeding component 7 and the shearing component 8; when the micro-tension conveying group 4 conveys the material under the drive of the lower transmission wheel group 2, since the rotation speed of the micro-tension conveying group 4 is faster than that of the feeding component 7 during the conveying process, it plays a pulling role on the material during high-speed shearing, avoiding bending and clogging of the material in the channel, and plays a good conveying role in high-speed shearing and ultra-thin material shearing; when the tail material feeding transmission group 5 is working, as long as the cylinder 31 pulls the movable slider 12 to move to the right on the transverse guide rail 11, the length of the upper transmission wheel 54 of the tail material feeding transmission group 5 corresponds to the lower transmission wheel 22, thereby playing a role of secondary conveying, and the tail material feeding transmission group 5 shortens the distance between the feeding component 7 and the shearing component 8, It is used for tail material transportation, shortens the tail material length, reduces waste, and improves the shearing accuracy.
