Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0031] It should be noted that all the directional indications in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0032] In the present application, unless otherwise clearly defined and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] In addition, in this application, descriptions such as "first" and "second" are for descriptive purposes only, and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments may be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0034] As Figures 1-9 shown, a steel structure sheet shearing device includes a power source 1. A friction rod 2 that realizes shearing through sliding is fixedly clamped at the output end of the power source 1. The power source 1 drives the friction rod 2 to move up and down. The power source 1 includes a housing 3. A clamping mechanism 4 is arranged at the clamping end of the housing 3. A connecting shaft 5 is fixedly installed at one end of the clamping mechanism 4 located inside the housing 3. A telescopic mechanism 6 for driving the connecting shaft 5 to move up and down is arranged inside the housing 3.

[0035] Convex teeth 8 are arranged in a circular distribution on the surface of the friction rod 2. The convex teeth 8 are divided into two groups. One group of convex teeth 8 inclines upward, and the other group of convex teeth 8 inclines downward. The two groups of convex teeth 8 are arranged in a circular array. Through the staggeredly distributed convex teeth 8, it can be ensured that the metal sheet can be cut during both the upward movement and the downward movement.

[0036] Polishing particles 9 are embedded on the surface of the friction rod 2. The polishing particles 9 are distributed in a circular pattern on the surface of the friction rod 2. By arranging the polishing particles 9, friction between the polishing particles 9 and the metal sheet is utilized, thereby enabling cutting.

[0037] A threaded portion 10 is arranged at the bottom end of the friction rod 2. The bottom end of the friction rod 2 is conical. A rotating mechanism 7 for driving the connecting shaft 5 to rotate is arranged inside the housing 3. By arranging the threaded portion 10 and the conical bottom end, it is convenient for the friction rod 2 to be inserted into the metal sheet and then cut.

[0038] A limiting disk 14 is fixedly installed at the front end of the connecting shaft 5. A limiting groove 15 adapted to the limiting disk 14 is opened at the front end of the housing 3. By arranging the limiting disk 14 and the limiting groove 15, the left - right swing of the connecting shaft 5 during the reciprocating movement can be restricted, reducing the width of the cutting groove.

[0039] The telescopic mechanism 6 includes a rotating disk 601. A protrusion 602 is fixedly installed on the edge of the upper surface of the rotating disk 601. Teeth 603 are provided on the outer surface of the rotating disk 601. A hinge rod 604 is hinged on the upper surface of the protrusion 602. A limit sliding sleeve 605 is hinged at one end of the hinge rod 604 away from the protrusion 602. The connecting shaft 5 is rotatably clamped in the middle of the limit sliding sleeve 605. The rotating disk 601 is driven to rotate by an external power mechanism, such as driving a gear to mesh with the teeth 603 by a motor. During the rotation of the rotating disk 601, the position of the protrusion 602 changes, and thus the limit sliding sleeve 605 can be driven by the hinge rod 604 to perform reciprocating motion, so that the reciprocating motion of the friction rod 2 can be realized.

[0040] The rotating mechanism 7 includes a bevel gear 701. A first square sleeve 702 is fixedly installed at one end of the bevel gear 701. A first square tube 713 is slidably connected inside the first square sleeve 702. The first square tube 713 is fixedly connected to the connecting shaft 5. The rotating mechanism 7 can drive the friction rod 2 to rotate, so that the contact position between the friction rod 2 and the metal plate can be changed, and thus the service life of the friction rod 2 can be improved. The bevel gear 701 is driven to rotate by an external power mechanism, and then the friction rod 2 can be driven to rotate, so that the angle switching of the friction rod 2 can be completed. The power mechanism for driving the rotating mechanism 7 can adopt the same power mechanism as the telescopic mechanism 6 and drive the rotating mechanism 7 to work slowly through a transmission mechanism, or a separate power mechanism can be set to intermittently drive the friction rod 2 to rotate.

[0041] The telescopic mechanism 6 includes a rotating plate 606 fixedly installed on the outer surface of the connecting shaft 5. Telescopic sleeves 607 are respectively arranged on both sides of the rotating plate 606. The telescopic function can be achieved by the alternating operation of the two telescopic sleeves 607. The power unit of the telescopic sleeve 607 can be an electromagnet, or pneumatic or hydraulic. The telescopic sleeve 607 is snap-connected inside the housing 3. The rotating mechanism 7 includes a spur gear 703. A second square sleeve 704 is fixedly installed at the front end of the spur gear 703. A second square tube 712 is slidably connected inside the second square sleeve 704. The second square tube 712 is fixedly connected to the connecting shaft 5. A driving gear 705 is meshed below the spur gear 703. The driving gear 705 is rotatably connected to the housing 3. A ratchet disc 706 is fixedly installed on the end face of the driving gear 705. A rotating sleeve 707 is arranged at the front end of the driving gear 705. A ratchet tooth 708 that meshes unidirectionally with the ratchet disc 706 is fixedly installed at the rear end of the rotating sleeve 707. A lead sleeve 709 is fixedly installed at the front end of the rotating sleeve 707. A lead shaft 710 is meshed in the middle of the lead sleeve 709. The lead shaft 710 is sleeved inside the rotating sleeve 707. A clamping frame 711 is fixedly installed at the front end of the lead shaft 710. The clamping frame 711 is snap-connected to the free end of the telescopic sleeve 607. The reciprocating movement of the clamping frame 711 can be driven by the operation of the free end of the telescopic sleeve 607, so that the lead shaft 710 can drive the lead sleeve 709 to rotate. Due to the unidirectional meshing of the ratchet disc 706 and the ratchet tooth 708, the driving gear 705 can be driven to rotate unidirectionally. Since the size of the spur gear 703 is larger than that of the driving gear 705, a speed reduction effect is achieved. When the telescopic sleeve 607 completes a telescopic process, the lead shaft 710 is only driven to rotate when it extends or retracts. The lead shaft 710 only drives the lead sleeve 709 to rotate a specified number of turns during one telescopic process. Therefore, the reciprocating speed of the friction rod 2 is much greater than the rotation speed of the friction rod 2, and the rotation of the friction rod 2 is intermittent.

[0042] A baffle 11 is slidably connected to the outer surface of the housing 3. An elastic telescopic rod 12 is fixedly installed at the bottom end of the baffle 11. A ball 13 is rotatably connected to the free end of the elastic telescopic rod 12. With such a setting, the elastic telescopic rod 12 can be used to support the housing 3, and the ball 13 facilitates the movement of the housing 3.

[0043] The outer surface of the outer shell 3 is fixedly installed with a limiting strip 16. A notch 17 adapted to the limiting strip 16 is provided in the inner ring of the baffle 11. A limiting ring 18 is fixedly installed at the front end of the outer shell 3. The baffle 11 is rotatably connected between the limiting strip 16 and the limiting ring 18. A positioning hole 19 is provided on the surface of the baffle 11. A sliding sleeve 20 is fixedly installed on the surface of the outer shell 3 on one side of the limiting strip 16. A plug rod 21 is slidably connected to the middle of the sliding sleeve 20. By rotating the baffle 11, the positioning hole 19 is located below the plug rod 21. Through such a setting, the baffle 11 can be slid along the limiting strip 16 for contraction, and the clamping mechanism 4 is exposed to facilitate the replacement of the friction rod 2. When the baffle 11 slides along the limiting strip 16 to the limiting ring 18, by rotating the baffle 11, the notch 17 is misaligned with the limiting strip 16, and the plug rod 21 is inserted into the positioning hole 19. At this time, the baffle 11 cannot move up and down or rotate, thereby facilitating the support of the outer shell 3.

[0044] During use, the friction rod 2 is fixed by the clamping mechanism 4. The telescopic mechanism 6 in the power source 1 drives the clamping mechanism 4 and the friction rod 2 to make telescopic movements, so that the convex teeth 8 of the friction rod 2 can be used to cut the plate. By externally pushing the outer shell 3 to move, multi-angle cutting of the plate can be performed.
