Description

Technical Field

[0001] This utility model belongs to the technical field of steel bar shearing devices, specifically relating to a flying shear device for steel bar production and processing. Background Technology

[0002] In the production and processing of steel bars, there is a shearing process. Using a flying shear device to cut the steel bars can precisely control the shearing length and position. For shearing small-diameter round steel bars, a common method is the hydraulic transmission flying shear method. The hydraulic transmission shearing machine uses hydraulic drive to shear, using the pressure energy provided by the hydraulic system to drive the hydraulic cylinder to drive the shears to perform the shearing action, which can cut the round steel bars into fixed lengths.

[0003] When a hydraulic shearing machine is used to shear small-diameter round steel bars, the hydraulic cylinder drives the upper shearing die holder to move downward. Under the coordinated action of the upper shearing die holder and the staggered lower die holder, the small-diameter round steel bar is sheared. The cut round steel bar is then manually removed. In the above operation, the cut round steel bar needs to be removed manually, which is cumbersome and has shortcomings.

[0004] Existing hydraulic transmission shearing devices, when used to shear small-diameter round steel bars, have the problem of lacking an automatic material feeding design that facilitates the cutting of the round steel bars. To address this, this application proposes a flying shear device for steel bar production and processing. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: a flying shear device for steel bar production and processing, including a hydraulic support, a base 11, guide pillars 12, a top seat 13, a hydraulic cylinder 14, and a shearing die holder 15 fixedly connected to the bottom end of the hydraulic cylinder 14. The two ends of the guide pillars 12 are respectively bolted to the base 11 and the top seat 13, and the guide pillars 12 are distributed between opposite corners of the base 11 and the top seat 13. The hydraulic cylinder 14 is fixed to the top seat 13 and the shearing die holder 15 by bolts. The structure and principle of the hydraulic cylinder 14 are existing technology and will not be described in detail in this application. When cutting round steel bar products, the round steel bar products are... Figure 2When the hydraulic cylinder 14 operates and becomes extended, it vertically moves the shearing die holder 15 downward. The shearing die holder 15 and the limiting lower die holder 21 are staggered, which can cut the workpiece B. The steel bar product limiting assembly includes the limiting lower die holder 21 fixed to the base 11 by bolts, the limiting post 212 of the vertical limiting lower die holder 21, the buffer spring 22 sleeved on the outside of the limiting post 212, and the buffer block 23 connected to the top of the buffer spring 22. The limiting post 212 is welded to the limiting lower die holder 21. When the shearing die holder 15 moves downward, it contacts the buffer block 23. The buffer block 23 and the buffer spring 22 reduce the downward force of the shearing die holder 15. The receiving part includes the fixed shaft 41 fixedly connected to the buffer block 23 and the flipping plate 4 rotatably connected to the fixed shaft 41. When the flipping plate 4 rotates in the direction a with the fixed shaft 41 as the axis, the cut workpiece B on the flipping plate 4 slides under the action of gravity. The automatic feeding effect is achieved. The pulling component includes a first fixed post 31 fixedly connected to the shearing die holder 15, a pull rope 32 connected to the first fixed post 31 at one end, a second fixed post 34 passing through the flip plate 4 and connected at the end of the corresponding pull rope 32, and a guide wheel seat 33 fixedly connected to the buffer block 23. When the shearing die holder 15 moves upward, the first fixed post 31 pulls the pull rope 32, the guide wheel seat 33 changes the direction of the force of the pull rope 32, and the pull rope 32 pulls the second fixed post 34 and the flip plate 4 to flip, which facilitates the workpiece B on the flip plate 4 to slide down. The reset component includes a spring shaft 51 installed inside the buffer block 23, a reset spring 52 sleeved on the outside of the spring shaft 51, and a connecting plate 53 connected to the end of the reset spring 52. When the flip plate 4 flips, the flip plate 4 and the connecting plate 53 squeeze the reset spring 52, and the reset spring 52 generates elastic force. When the shearing die holder 15 moves downward, the flip plate 4 is reset by the elastic force and catches the round steel bar.

[0027] In this embodiment, a circular hole is provided on the lower limiting mold base 21, and the side of the shearing mold knife holder 15 is in contact with the surface of the lower limiting mold base 21. The lower limiting mold base 21 has an "L" shaped structure, and the top of the lower limiting mold base 21 and the shearing mold knife holder 15 are staggered. The hydraulic cylinder 14 moves the shearing mold knife holder 15 vertically downward. The shearing mold knife holder 15 and the lower limiting mold base 21 are staggered, which can cut the workpiece B.

[0028] In this embodiment, a guide cylinder 211 is glued to the lower mold base 21. The guide cylinder 211 vertically limits the lower mold base 21. A through hole is provided at the corner of the buffer block 23 for the guide cylinder 211 to pass through. The top of the guide cylinder 211 is inserted into the through hole at the corner of the buffer block 23. The guide cylinder 211 limits the buffer block 23 and prevents the buffer block 23 from deflecting.

[0029] In this embodiment, both ends of the second fixing post 34 are circular rings. One end of the pull rope 32 is fixedly connected to the circular ring end of the second fixing post 34. The pull rope 32 can pull the second fixing post 34. The pull rope 32 is made of a high-strength and tensile-resistant alloy material, such as aluminum alloy.

[0030] In this embodiment, the end of the first fixed post 31 of the cylindrical structure away from the shearing die holder 15 is a "T" shaped structure. A concave first annular groove is formed on the outer surface of the "T" shaped end of the first fixed post 31. One end of the pull rope 32 is sleeved in the first annular groove. A concave second annular groove is formed on the guide wheel seat 33 for the pull rope 32 to pass through. The pull rope 32 is limited by the guide wheel seat 33 and slides in a predetermined direction. When the shearing die holder 15 moves upward, the first fixed post 31 pulls the pull rope 32, and the guide wheel seat 33 changes the direction of the force of the pull rope 32. The pull rope 32 pulls the second fixed post 34 and the flipping plate 4 to flip.

[0031] In this embodiment, one end of the flip plate 4 is a curved plate in the shape of a semi-circular ring. The connecting plate 53 is fixed to the bottom surface of the flip plate 4 by bolts. When the flip plate 4 flips, the cut workpiece B on the flip plate 4 slides down under the action of gravity.

[0032] Working principle and usage process of this utility model:

[0033] In the initial state, there is a gap between the limiting lower mold base 21 and the shearing mold cutter 15. At this time, the flipping plate 4 is in an inclined state, and the return spring 52 is in a compressed state that generates a return force.

[0034] When the round steel bar is cut, the round steel bar passes through the limiting lower die holder 21, and the hydraulic cylinder 14 drives the shearing die holder 15 to move down;

[0035] With the pull rope 32 in a loose state, the flip plate 4 rotates and resets under the elastic force of the reset spring 52;

[0036] The top of the limiting lower die holder 21 and the shearing die holder 15 are staggered. The downward-moving shearing die holder 15 will cut the round steel bar that passes through the limiting lower die holder 21, and the cut round steel bar will fall on the surface of the flip plate 4.

[0037] Hydraulic cylinder 14 drives shearing die holder 15 to move upward, first fixed column 31 pulls pull rope 32, guide wheel seat 33 changes the direction of force of pull rope 32, pull rope 32 pulls second fixed column 34 and flip plate 4 to flip, which facilitates the workpiece B on flip plate 4 to slide down, and has the function of automatically dropping the cut round steel bar.

[0038] In summary: The material feeding design of this application facilitates the automatic falling of the cut round steel bar. The downward-moving shearing die holder 15 cuts the round steel bar that has passed through the limiting lower die holder 21. The cut round steel bar falls on the surface of the flipping plate 4. The hydraulic cylinder 14 drives the shearing die holder 15 to move upward, and the pull rope 32 pulls the flipping plate 4 to flip. The cut round steel bar falls automatically under the action of gravity.

[0039] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
