Description

Technical Field

[0001] The utility model relates to the technical field of plate shearing machines, in particular to a plate shearing machine with stable processing. Background Art

[0002] The Chinese patent application number: CN202221572961.6 proposes a high-stability shearing machine. The guide block cooperates with the guide groove to greatly improve the stability of the tool during the downward pressing process, thereby ensuring the shearing accuracy. The anti-slip pad at the bottom of the guide rod is pressed and fixed to the shearing plate, thereby ensuring the stability of the metal plate during the shearing process. However, the shearing machine has the following defects:

[0003] There is no limiting mechanism on the side end of the sheet. During shearing, one end of the sheet is placed on the extension table while the other end is suspended in the air, which causes the sheet to easily shake left and right during shearing, resulting in certain deformation at the cut, thereby reducing the shearing quality and processing stability of the sheet.

[0004] Therefore, in order to solve the defect that the shearing machine cannot limit and support the sheet metal when in use, it is necessary to propose a shearing machine with stable processing. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] To solve the technical problem of how the sheet metal is supported during shearing, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0026] A stable shearing machine comprises a machine base 1 and a side plate 2, the machine base 1 comprises a shearing table 11, a material discharge slope 13, a material collection trough 14 and a limit plate 18, a sliding door 141 is slidably installed at one end of the material collection trough 14, a lower knife group 12 is installed at the end of the shearing table 11, first slide grooves 15 are symmetrically opened on both sides of the upper ends of the material discharge slope 13 and the material collection trough 14, a support plate 16 is slidably connected in the first slide groove 15, a side push cylinder 17 is installed at the side end of the machine base 1, the side push cylinder 17 is connected to the support plate 16 through a piston rod, and the bottom end of the limit plate 18 is in contact with the top end of the support plate 16.

[0027] It should be noted that the upper end surfaces of the shearing table 11, the lower knife group 12 and the support plate 16 are all located on the same horizontal line. The limit plate 18 can limit the front end of the sheet material, which is conducive to determining the length of the sheet material to be sheared. At the same time, it can also prevent the sheet material from sliding forward during shearing. After the sheet material is sheared, it will continue to stay on the support plate 16. The limit plate 18 will separate the sheet material from the support plate 16 until the sheet material falls on the unloading slope 13 to facilitate unloading.

[0028] Specifically, the sheet material is placed on the shearing table 11 and pushed forward until the front end of the sheet material abuts against the limit plate 18. At this time, the sheet material to be sheared is facing the lower knife group 12. The side push cylinder 17 is started, and the side push cylinder 17 drives the support plate 16 to slide in the first slide groove 15 until one end of the support plate 16 is in contact with the lower knife group 12. At this time, the sheet material is supported on the support plate 16 and the shearing table 11 to prevent the sheet material from tilting or twisting due to one end being suspended during shearing.

[0029] In order to solve the technical problem of how to limit the position of the sheet metal during shearing, please refer to Figure 4-Figure 5 , this embodiment provides the following technical solutions:

[0030] A positioning rod 281 is movably inserted through the rod sleeve 29 on the side panel 2. The positioning rod 281 is provided with multiple positioning holes and is fixed to the rod sleeve 29 through a positioning pin. One end of the positioning rod 281 located inside the side panel 2 is fixedly connected to a clamping plate 28, and a plurality of rollers 282 are installed on the clamping end of the clamping plate 28.

[0031] Specifically, after the sheet is placed on the shearing table 11 and the support plate 16, the left and right clamping plates 28 are pushed until the side ends of the rollers 282 fit with the side ends of the sheet, and then the positioning pins are used to fix the positioning rod 281 and the rod sleeve 29 to achieve left and right position limiting of the sheet.

[0032] To solve the technical problem of how to press and fix the sheet when cutting, please refer to Figure 4-Figure 5 , this embodiment provides the following technical solutions:

[0033] A downward pressure cylinder 22 is installed at the top of the side plate 2, and the downward pressure cylinder 22 is connected to a lifting plate 23 through a piston rod. An upper knife group 24 is installed at the lower end of the lifting plate 23. Slide blocks 231 are symmetrically provided at the left and right ends of the lifting plate 23. A second slide groove 21 is opened on the inner wall of the side plate 2, and the second slide groove 21 and the slide block 231 form a sliding connection.

[0034] The front and rear ends of the lifting plate 23 are movably interspersed with a pressing column 25, the bottom end of which is fixedly connected to a pressing plate 26. A spring 27 is wound around the pressing column 25, one end of the spring 27 is fixed to the lower surface of the lifting plate 23, and the other end is fixed to the upper surface of the pressing plate 26.

[0035] Specifically, when it is necessary to shear the sheet material, the downward pressure cylinder 22 is started, and the downward pressure cylinder 22 drives the lifting plate 23 to move downward. Through the cooperation of the second slide groove 21 and the slider 231, the stability of the upper knife group 24 during the downward pressure process is greatly improved. At the same time, before the upper knife group 24 shears, the pressure plate 26 will first fit with the surface of the sheet material, and as the lifting plate 23 moves downward, the spring 27 is compressed, so that the top of the pressure column 25 extends out of the lifting plate 23. Through the pressure columns 25 and the pressure plates 26 arranged at the front and back, the front and rear ends of the sheet material can be pressed and fixed to avoid fixing one end and causing the other end to tilt.

[0036] Working principle: When using this stable shearing machine, first place one end of the sheet material on the shearing table 11, and then push the sheet material until the front end of the sheet material fits with the limit plate 18. At this time, the sheet material to be sheared is aligned with the lower knife group 12, and then the side push cylinder 17 is started. The side push cylinder 17 drives the support plate 16 to slide in the first slide groove 15 until the side end of the support plate 16 fits with the lower knife group 12. At this time, the sheet material is located on the support plate 16 and the shearing table 11, and the left and right clamping plates 28 are pushed until the side end of the sheet material fits with the side end of the roller 282, and then the positioning pin is used to align the positioning rod 281 with the rod sleeve 2 9 is fixed, the downward pressure cylinder 22 is started, and with the cooperation of the slider 231 and the second slide groove 21, the lifting plate 23 drives the upper knife group 24 to move downward until the pressure plate 26 fits the surface of the sheet material, and the sheet material is pressed and fixed. At this time, the lifting plate 23 continues to move downward, the spring is compressed 27, and the top of the pressure column 25 extends out of the lifting plate 23 until the upper knife group 24 shears the sheet material. The sheared sheet material is located on the support plate 16, and the side push cylinder 17 is started. The side push cylinder 17 drives the support plate 16 to move in the opposite direction. Under the action of the limit plate 18, the sheared sheet material falls on the discharge slope 13 and slides into the collecting trough 14.
