Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, and particularly relates to a plate positioning device for a plate shearing machine. Background Technique

[0002] A plate shearing machine is a mechanical device used for shearing metal plates, and is widely applied to fields such as metal processing, manufacturing, and construction. It cuts the plate through the relative movement of a pair of blades (an upper blade and a lower blade) to make the plate reach the required size and shape. However, when the existing plate shearing machine shears the plate, it is unable to accurately position the plate, resulting in deviation in the size of the sheared plate and reducing the shearing accuracy.

[0003] Therefore, in order to solve the defect that the plate shearing machine cannot position the plate, resulting in a decrease in shearing accuracy, it is very necessary to propose a plate positioning device for a plate shearing machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plate positioning device for a plate shearing machine, which realizes the adjustment of the cutting length of the plate by accurately adjusting the position of the positioning frame, thereby improving the cutting accuracy. The front and rear fixing plates can press and fix the plate during plate cutting to prevent cutting deviation caused by the movement of the plate during cutting, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A plate positioning device for a plate shearing machine includes a plate shearing machine and a roller conveyor installed at the front end of the plate shearing machine. A positioning mechanism is installed at the rear end of the plate shearing machine. A threaded rod is movably installed in the body of the positioning mechanism. One end of the threaded rod is fixedly connected to a motor, and a positioning frame is threadedly connected to the rod body.

[0007] A fixing groove is formed in the positioning frame, and a third hydraulic cylinder is fixedly installed at the top of the positioning frame. The output end of the third hydraulic cylinder penetrates through the positioning frame and is connected to a second fixing plate. The left and right ends of the second fixing plate are slidably connected to the inner wall of the positioning frame.

[0008] Preferably, a first hydraulic cylinder is fixedly installed at the top of the plate shearing machine. The output end of the first hydraulic cylinder penetrates through the plate shearing machine and is connected to a tool holder. The left and right ends of the tool holder are slidably connected to the inner wall of the plate shearing machine.

[0009] Preferably, an upper blade is installed at the bottom of the tool holder, and a lower blade is installed at a position directly below the upper blade on the plate shearing machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] To solve the technical problem of how the shearing machine cuts the plate, please refer to Figures 1-3, this embodiment provides the following technical solutions:

[0021] A sheet metal positioning device for a shearing machine, comprising a shearing machine 1 and a roller conveyor 2 installed at the front end of the shearing machine 1. A first hydraulic cylinder 11 is fixedly installed at the top of the shearing machine 1. The output end of the first hydraulic cylinder 11 penetrates through the shearing machine 1 and is connected to a tool holder 12. The left and right ends of the tool holder 12 are slidably connected to the inner wall of the shearing machine 1. An upper blade 13 is installed at the bottom of the tool holder 12. A lower blade 14 is installed at the position of the shearing machine 1 directly below the upper blade 13.

[0022] Specifically, the sheet metal is fed through the roller conveyor 2 until the part of the sheet metal to be cut is moved above the lower blade 14. Then, the first hydraulic cylinder 11 is started. The first hydraulic cylinder 11 drives the tool holder 12 and the upper blade 13 to move downward. At this time, the upper blade 13 and the lower blade 14 form a pair of shearing blades. The sheet metal located between them is cut through the relative movement of the upper blade 13 and the lower blade 14, so that the sheet metal is sheared between the blades.

[0023] To solve the technical problem of how the shearing machine positions the sheet metal, please refer to Figures 1-3 , this embodiment provides the following technical solutions:

[0024] A positioning mechanism 4 is installed at the rear end of the shearing machine 1. A threaded rod 42 is movably installed inside the body of the positioning mechanism 4. One end of the threaded rod 42 is fixedly connected to a motor 43, and a positioning frame 44 is threadedly connected to its rod body. A fixing groove 45 is formed inside the positioning frame 44.

[0025] A scale 41 is marked on the surface of the body of the positioning mechanism 4. The starting end of the scale 41 corresponds to the position of the lower blade 14. The left and right ends of the positioning frame 44 are slidably connected to the scale 41.

[0026] Among them, the inner wall of the fixing groove 45 is perpendicular to the measuring end of the positioning frame 44, and the starting end of the scale 41 corresponds to the position of the lower blade 14. The purpose of such a design is that when the front end of the sheet metal is transported into the fixing groove 45 and abuts against the inner wall of the fixing groove 45, the sheet metal can no longer be transported at this time. The value displayed by the outermost end of the positioning frame 44 on the scale 41 is the cutting length of the sheet metal. Therefore, by adjusting the position of the positioning frame 44, the cutting length of the sheet metal can be adjusted.

[0027] Specifically, before loading the board material, first start the motor 43 to drive the threaded rod 42 to rotate. At this time, the positioning frame 44 moves back and forth along the axial direction of the threaded rod 42. The operator can observe the value corresponding to the positioning frame 44 on the outside of the scale 41 until the value is the same as the length to be cut. Then, turn off the motor 43. At this time, the position adjustment of the positioning frame 44 is completed. Then, place the board material on the roller conveyor 2 for loading until the front end of the board material moves into the fixed slot 45 and abuts against the inner wall of the fixed slot 45. At this time, the part of the board material located above the lower blade 14 is the required cutting part.

[0028] To solve the technical problem of how to fix the board material on the shearing machine, please refer to Figures 1-3 This embodiment provides the following technical solutions:

[0029] A third hydraulic cylinder 46 is fixedly installed at the top of the positioning frame 44. The output end of the third hydraulic cylinder 46 penetrates the positioning frame 44 and is connected to a second fixing plate 47. The left and right ends of the second fixing plate 47 are slidably connected to the inner wall of the positioning frame 44.

[0030] A fixing assembly 3 is installed at one end of the roller conveyor 2 close to the shearing machine 1. The fixing assembly 3 includes a second hydraulic cylinder 31. The second hydraulic cylinder 31 is fixedly installed on the roller conveyor 2. The output end of the second hydraulic cylinder 31 is connected to a first fixing plate 32. The left and right ends of the first fixing plate 32 are slidably connected to the inner wall of the roller conveyor 2.

[0031] It should be noted that the upper end of the roller conveyor 2 is kept level with the cutting table and the bottom of the fixed slot 45, so that when loading the board material, the front end of the board material can pass through the cutting table and be transported into the fixed slot 45.

[0032] Specifically, after the board material is positioned, start the third hydraulic cylinder 46 and the second hydraulic cylinder 31. The third hydraulic cylinder 46 drives the second fixing plate 47 to move downward until the front end of the board material is pressed and fixed. The second hydraulic cylinder 31 drives the first fixing plate 32 to move downward until the rear end of the board material is pressed and fixed, realizing the front and rear fixation of the board material during cutting and preventing the board material from shifting during cutting.

[0033] Working principle: For the sheet positioning device of this shearing machine, before the sheet is loaded, first start the motor 43 to drive the threaded rod 42 to rotate. At this time, the positioning frame 44 moves back and forth along the axial direction of the threaded rod 42. The operator can observe the value corresponding to the positioning frame 44 on the outside of the scale 41 until the value is the same as the length to be cut. Then, turn off the motor 43. At this time, the position adjustment of the positioning frame 44 is completed. Then, place the sheet on the roller conveyor 2 for loading until the front end of the sheet moves into the fixed groove 45 and abuts against the inner wall of the fixed groove 45. At this time, the part of the sheet located above the lower blade 14 is the required cutting part. Then, drive the second hydraulic cylinder 31 and the third hydraulic cylinder 46 to press and fix the front and rear ends of the sheet. Finally, start the first hydraulic cylinder 11 to drive the upper blade 13 to move down, and realize the cutting of the sheet through the relative movement of the upper blade 13 and the lower blade 14.
