Description

Technical Field

[0001] The present invention relates to the technical field of mechanical applications, and more particularly to a rotary shearing machine. Background Art

[0002] A shearing machine is an essential mechanical equipment in the rolling mill workshop for shearing the heads, tails, edges and corners, and fixed-length of steel bars. It is an indispensable bar shearing equipment in the high-precision metal processing industry and is widely used in the metallurgical, mining, construction, and building manufacturing industries.

[0003] Currently, the working mode of the shearing machine is as follows: relying on the feeding mechanism to feed the long steel bars. While feeding, the long steel bars are cut into small sections by the blade rotary shearing. Using the blade edge to shear, on the one hand, it requires the edge to be sharp, and on the other hand, the blade edge is easily damaged, resulting in large blade loss, high usage cost, and high manufacturing cost.

[0004] Therefore, the operation of the shearing machine actually requires the coordinated cooperation of the feeding mechanism and the shearing blade, and the power of the two parts is required to cut the long steel bars together, with a complex structure.

[0005] Therefore, to solve the above problems, a rotary shearing machine with a simple structure and easy to operate is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide a rotary shearing machine to solve the problems existing in the prior art mentioned in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: A rotary shearing machine, which includes a lower rotary base. A support base rotary is arranged on the lower rotary base. A rotary support base is arranged on the support base rotary. A bearing is arranged on the rotary support base and a support sleeve is provided. A shearing knife round wheel is fixed in the support sleeve. A circumferential wire groove is arranged in the middle of the shearing knife round wheel. Shearing knife round wheel support devices are arranged on both sides of the shearing knife round wheel and the support sleeve. On the left and right sides of the support sleeve, a first support of the cutting knife round wheel and a second support of the cutting knife round wheel are respectively arranged. A pressing wheel connecting support frame is connected to the first support of the cutting knife round wheel and the second support of the cutting knife round wheel through a pressing wheel pin shaft. Cutting knives are symmetrically arranged on the inner side of the pressing wheel pin shaft through bearings.

[0008] Further, both sides of the lower rotary base and the support base rotary are fixed by T-shaped bolts. A rotary positioning pin passing through the support base rotary is arranged inside the bottom of the lower rotary base.

[0009] Further, the shearing knife round wheel support device includes a connecting flange, a round wheel main shaft, and a bearing cover plate. The round wheel main shaft passes through the support sleeve, with a connecting flange fixed on one side and a bearing cover plate covering the other side.

[0010] Further, the cutting knives are symmetrically installed in front of the shearing knife circular wheel and are rotationally connected to the shearing knife circular wheel through latches. The convex extrusion surface on the outer side below the cutting knives is extrusion-connected to the press wheel pin shaft, and the cutting knife surfaces below the cutting knives are all arranged inward.

[0011] Further, a return spring is provided between the cutting knives.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the rotation of the shearing knife circular wheel, the cutting knives are driven to rotate, so that the press wheel pin shafts on both sides of the cutting knives press the convex extrusion surfaces of the cutting knives during the rotation process, causing the cutting blades of the cutting knives to close inward, which has the effect of cutting long steel bars, and reduces the power setting of the rotary cutting machine, simplifies the mechanism of the rotary cutting machine, and is more conducive to popularization.

[0016] Please refer to Figures 1 - 3 , an embodiment provided by the present invention: A rotary shearing machine of the present invention. The shearing machine body includes a rotary table lower seat 1, on which a bracket base rotary table 2 is provided. On the bracket base rotary table 2, a rotary table support seat 3 is provided. On the rotary table support seat 3, a bearing 6 and a support sleeve 7 are provided. A shearing knife round wheel 8 is fixed inside the support sleeve 7. A circumferential steel wire groove 19 is provided in the middle of the shearing knife round wheel 8. On both sides of the shearing knife round wheel 8 and the support sleeve 7, a shearing knife round wheel support device is provided. On the left and right sides of the support sleeve 7, a first cutter round wheel bracket 12 and a second cutter round wheel bracket 13 are respectively provided. A pressing wheel connecting support frame 15 is connected to the first cutter round wheel bracket 12 and the second cutter round wheel bracket 13 through a pressing wheel pin shaft 14. Inside the pressing wheel pin shaft 14, a cutting knife 17 is symmetrically arranged through a bearing 16.

[0017] In the above technical solution, the shearing knife round wheel 8 is fixed by the support sleeve 7. A circumferential steel wire groove 19 for the steel bar to surround and penetrate is provided in the middle of the shearing knife round wheel 8. During the operation of the shearing knife round wheel 8, the steel bar is conveyed forward, and the cutting knife 17 is used to cut it. The cutting work of the cutting knife 17 is realized through the pressing wheel pin shaft 14.

[0018] Both sides of the rotary table lower seat 1 and the bracket base rotary table 2 are fixed by T-shaped bolts 5. A rotary table positioning pin 4 passing through the bracket base rotary table 2 is arranged inside the bottom of the rotary table lower seat 1.

[0019] In the above technical solution, the double fixation between the rotary table lower seat 1 and the bracket base rotary table 2 is realized through the rotary table positioning pin 4 and the T-shaped bolts 5, making the connection between the two more firm.

[0020] The shearing knife round wheel support device includes a connecting flange 9, a round wheel main shaft 10 and a bearing cover plate 11. The round wheel main shaft 10 passes through the support sleeve 7. A connecting flange 9 is fixed on one side, and a bearing cover plate 11 is covered on the other side.

[0021] In the above technical solution, the shearing round wheel support device is used to reinforce the shearing knife round wheel 8. The round wheel main shaft 10 passes through the support sleeve 7 to support the shearing knife round wheel 8. A connecting flange 9 is fixed on one side, and a bearing cover plate 11 is fixed on the other side, playing a role of fixing and sealing.

[0022] The cutting knives 17 are symmetrically installed in front of the shearing knife round wheel 8 and are rotatably connected to the shearing knife round wheel 8 through a lock 171.

The cutting knife surfaces 173 below the cutting knives 17 are all arranged inward. A return spring 18 is provided between the cutting knives 17.

[0023] In the above technical solution, the rotation of the shearing knife round wheel 8 drives the cutting knife 17 to rotate, so that the pressing wheel pin shafts 14 on both sides of the cutting knife 17 press the convex extrusion surface 172 of the cutting knife during the rotation process, causing the cutting blades 173 of the cutting knife 17 to close inwards, which has the effect of cutting the long steel bars, reduces the power setting of the rotary cutting machine, simplifies the mechanism of the rotary cutting machine, and is more conducive to popularization. During operation, when the shearing knife round wheel 8 conveys the steel bar, the rotation of the shearing knife round wheel 8 can drive the cutting knife 17 to rotate together. At the same time, the convex extrusion surface 172 on the lower outer side of the rotating cutting knife 17 touches the pressing wheel pin shaft 14. Under the action of the return spring 18, the pressing wheel pin shaft 14 presses the cutting knife 17 to tighten inwards, and the cutting knife 17 rotates inwards along the buckle 171, causing the cutting knife surface 173 to gradually approach until the steel bar is cut. After cutting the steel bar, the shearing knife round wheel 8 rotates in the reverse direction and resets, causing the cutting knife 17 to disengage from the pressing wheel pin shaft 14, and also reset under the action of the return spring 18, and starts the next round of cutting the steel bar.
