Description

Technical Field

[0001] This utility model belongs to the field of shearing machine technology, specifically relating to a shearing machine anti-skid device. Background Technology

[0002] A shearing machine is a machine used to cut metal sheets into small pieces according to a predetermined size. It is widely used in many fields such as machinery manufacturing, automobile industry, shipbuilding, and steel structure construction.

[0003] In the actual use of the shearing machine, it was found that when the shearing machine is cutting metal sheets, the metal sheets located on both sides of the shear blade will lift up or even jump. The jumping problem of the shearing machine refers to the phenomenon that the sheet being cut is not cut smoothly under the action of the shear blade during the shearing process, but jumps up or bounces.

[0004] Sheet bounce can cause uneven shearing surfaces, resulting in defects such as burrs and wavy patterns. This can lead to problems in subsequent processing or affect the assembly accuracy of the product. Due to sheet bounce, multiple shearing operations may be required to cut the sheet, which undoubtedly reduces the working efficiency of the shearing machine. To address these issues, an anti-bounce device for shearing machines is proposed. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a shearing machine anti-skid device; it has a good ability to stabilize metal sheets and effectively suppresses skid problems.

[0006] This utility model provides a shearing machine anti-skid device, including a workbench with symmetrically arranged conveyor belts and a bracket fixedly installed between the conveyor belts. An anti-skid shearing assembly is provided on the workbench corresponding to the bracket. The anti-skid shearing assembly includes an electro-hydraulic rod symmetrically fixedly installed below the bracket. A pressing plate is fixedly installed on the movable end of the electro-hydraulic rod. An upper shear blade is bolted to the lower end of the pressing plate. A base plate is fixedly installed on the workbench corresponding to the pressing plate. A lower shear blade is screwed to the base plate corresponding to the upper shear blade. A movable rod is symmetrically inserted and connected to the pressing plate near the upper shear blade. A limit plate is fixedly installed on the upper end of the movable rod extending from the pressing plate, and a stabilizing plate is fixedly installed on the lower end of the movable rod.

[0007] Furthermore, protective nets are symmetrically and fixedly installed on the workbench corresponding to the conveyor belt.

[0008] Furthermore, the workbench is provided with a direction indicator on its side.

[0009] Furthermore, the pressing plate is slidably connected to the inner wall of the bracket.

[0010] Furthermore, a limit ring is fixedly installed on the movable rod, and a spring is fixedly installed on the limit ring. The other end of the spring is fixedly connected to the pressing plate.

[0011] Furthermore, the lower side of the stabilizing plate is uniformly provided with several rubber pads.

[0012] Furthermore, a limit rod is inserted between the pressing plate and the base plate.

[0013] The beneficial effects of this utility model are:

[0014] This invention optimizes and improves the structure of a traditional shearing machine by adding a structure to stabilize the metal sheet. Structures that can stably press down on the sheet material on both sides of the shearing process improve the stability of the sheet during shearing, increasing overall work efficiency, improving product quality, and protecting the shear blades for long-term effective use.

[0021] 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.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please refer to the accompanying diagrams in all instruction manuals:

[0024] A shearing machine anti-skid device includes a workbench 1, conveyor belts 2 symmetrically arranged on the workbench 1, and brackets 3 fixedly installed between the conveyor belts 2. Anti-skid shearing components are provided on the workbench 1 corresponding to the brackets 3.

[0025] The anti-skid shear assembly includes an electro-hydraulic rod 4 symmetrically fixedly installed below the bracket 3. A pressing plate 5 is fixedly installed on the movable end of the electro-hydraulic rod 4. An upper shear blade 6 is bolted to the lower end of the pressing plate 5. A base plate 7 is fixedly installed on the worktable 2 corresponding to the pressing plate 5. A lower shear blade 8 is bolted to the base plate 7 corresponding to the upper shear blade 6. A movable rod 9 is symmetrically inserted and connected to the pressing plate 5 near the upper shear blade 6. A limit plate 10 is fixedly installed on the upper end of the movable rod 9 extending from the pressing plate 5. A stabilizing plate 11 is fixedly installed on the lower end of the movable rod 9. It should be noted that when the pressing plate 5 is suspended and waiting to work, the horizontal height of the stabilizing plate 11 is lower than the horizontal height of the upper shear blade 6. This ensures that the stabilizing plate 11 contacts the metal plate first and presses down on the metal plate during the descent of the pressing plate 5.

[0026] As described above, the metal sheet to be processed is placed on the corresponding conveyor belt 2. After being conveyed by the conveyor belt 2, it enters the middle between the upper shear blade 6 and the lower shear blade 8. The electric hydraulic rod 4 is controlled to work, driving the pressing plate 5 to descend. During the descent of the pressing plate 5, the stabilizing plate 11 first presses down on the metal sheet to provide it with a stable working environment. Then, the upper shear blade 6 and the lower shear blade 8 interact to cut the metal sheet. After cutting, the electric hydraulic rod 4 lifts the pressing plate. After the upper shear blade 6 and the lower shear blade 8 separate, the stabilizing plate 11 will leave the metal sheet under the control of the limiting plate 10 on the movable rod 9. The metal sheet will then proceed to the next step of processing under the conveyor belt 2.

[0027] As a technical optimization of this utility model, a protective net 12 is symmetrically and fixedly installed on the workbench 1 corresponding to the conveyor belt 2;

[0028] As can be seen from the above description, the protective net 12 can prevent sudden accidents from occurring when the metal sheet on the conveyor belt 2 is being cut, and can protect the workers outside the workbench when metal splashes occur.

[0029] As a technical optimization of this utility model, the side of the workbench 1 is provided with a direction indicator 13;

[0030] As can be seen from the above description, the direction indicator 13 can help workers see the direction of their work clearly, avoid errors in the opposite direction, and prevent work accidents.

[0031] As a technical optimization of this utility model, the pressing plate 5 is slidably connected to the inner wall of the bracket 3;

[0032] As can be seen from the above description, the sliding connection method makes the pressing plate 5 more stable during the lifting process, while ensuring the working efficiency of the upper shear blade 6 and the lower shear blade 8.

[0033] As a technical optimization of this utility model, a limiting ring 14 is fixedly installed on the movable rod 9, and a spring 15 is fixedly installed on the limiting ring 14. The other end of the spring 15 is fixedly connected to the pressing plate 5.

[0034] As can be seen from the above description, the spring 15 can provide continuous downward pressure to the movable rod 9, so that the pressure of the stabilizing plate 11 on the metal plate is not only its own weight, but also has better stability.

[0035] As a technical optimization of this utility model, a plurality of rubber pads 16 are evenly provided on the lower side of the stabilizing plate 11.

[0036] As can be seen from the above description, the rubber pad 16 can utilize the characteristics of the material itself to protect the appearance of the metal sheet while compressing it, and can also provide sufficient friction to optimize the stability of the metal sheet.

[0037] As a technical optimization of this utility model, a limiting rod 17 is inserted between the pressing plate 5 and the base plate 7;

[0038] As can be seen from the above description, the connection of the limiting rod 17 can improve the stability of the pressing plate 5 and the base plate 7.

[0039] Working principle:

[0040] The metal sheet to be processed is placed on the corresponding conveyor belt 2 according to the direction indicated by the direction indicator 13. After being conveyed by the conveyor belt 2, it enters the middle between the upper shear blade 6 and the lower shear blade 8. The electric hydraulic rod 4 is controlled to work, driving the pressing plate 5 to descend. During the descent of the pressing plate 5, the stabilizing plate 11 first presses down on the metal sheet. Using the weight of the stabilizing plate 11 and the elastic force applied by the spring 15, and with the help of the rubber pad 16, it obtains a stable working environment. Then, the upper shear blade 6 and the lower shear blade 8 interact to cut the metal sheet. After cutting, the electric hydraulic rod 4 lifts the pressing plate. After the upper shear blade 6 and the lower shear blade 8 separate, the stabilizing plate 11 will leave the metal sheet under the control of the limiting plate 10 on the movable rod 9. The metal sheet is then conveyed by the conveyor belt 2 to the next step of processing.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
