Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic shearing machines, in particular to a lower knife frame assembly of a hydraulic shearing machine. Background Art

[0002] The hydraulic shearing machine is a machine that uses a moving upper blade and a fixed lower blade, and adopts a reasonable blade gap to apply shear force to metal plates of various thicknesses, so that the plates are broken and separated according to the required size.

[0003] When the hydraulic shearing machine is operating, it is necessary to perform upper and lower knife operations. At this time, an upper knife holder and a lower knife holder need to be configured. The upper knife holder is used to control the movement of the knife of the hydraulic shearing machine, and the lower knife holder is used to contact the knife when cutting, and cooperate with the bracket to carry the plate to be sheared.

[0004] When the hydraulic shearing machine is in use, the traditional lower tool holder often uses an integrated structure. In this way, if the position of the lower tool is not controlled well, the tool is likely to collide with the base, which can easily cause damage to the tool. The existing structure is studied and improved, and a hydraulic shearing machine lower tool holder assembly is provided to achieve a more practical purpose. Utility Model Content

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Example 1

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the first embodiment of the utility model, and provides a lower knife frame assembly of a hydraulic shearing machine, including a base 1, a plurality of first-class knife grooves 2 and second-class knife grooves 3 are opened on the top of the base 1, and a lower knife deceleration assembly 4 is arranged inside the first-class knife grooves 2 and the second-class knife grooves 3, positioning openings 5 ​​are arranged at both ends of the base 1, and stable supports 6 are fixedly arranged at both ends of the side of the base 1;

[0036] Specifically, the base 1 includes an integrated lower plate 101 and an upper plate 102 , and the width of the upper plate 102 is smaller than that of the lower plate 101 .

[0037] Furthermore, by limiting the width of the lower plate 101 and the upper plate 102 , a structure with a narrow top and a wide bottom is formed, which is beneficial to improving the stability of the entire base 1 .

[0038] Specifically, the number of the first-type cutting grooves 2 is four, the number of the second-type cutting grooves 3 is two, and the two first-type cutting grooves 2 are symmetrically distributed on both sides of the same second-type cutting groove 3 .

[0039] Furthermore, by providing the first type of tool groove 2 and the second type of tool groove 3, a buffer space for the tool can be provided when the tool of the hydraulic shearing machine falls and performs shearing operations.

[0040] Specifically, the widths of the first type of knife groove 2 and the second type of knife groove 3 are the same, and the length of the first type of knife groove 2 is greater than the length of the second type of knife groove 3 .

[0041] Furthermore, the first type of tool groove 2 and the second type of tool groove 3 can be adapted to the size of the tool of the hydraulic shearing machine, avoiding collision between the tool and the base 1, thereby protecting the tool.

[0042] Specifically, an arc-shaped notch 201 is opened at one end of the side surface of the first-type knife groove 2, and a square notch 301 is opened in the middle of the side surface of the second-type knife groove 3.

[0043] Furthermore, the air permeability area of ​​the knife groove 2 can be increased by the arc-shaped notch 201, thereby preventing the lower knife deceleration component 4 from being unable to move freely due to air pressure.

[0044] Example 2

[0045] Reference Figure 4 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment. The lower knife deceleration component 4 includes a contact panel 401. A plurality of evenly arranged spring columns 402 are fixedly provided at the bottom end of the contact panel 401. The bottom end of the spring column 402 is fixedly connected to a pressure detection substrate 403. The inner bottoms of the first type of knife groove 2 and the second type of knife groove 3 are fixedly welded to the corresponding pressure detection substrate 403 respectively.

[0046] Specifically, the touch panel 401 includes a rubber layer 4011 and a hard metal plate 4012 that are fixed integrally, and the rubber layer 4011 is arranged directly above the hard metal plate 4012 .

[0047] Furthermore, when the tool contacts the contact panel 401, the rubber layer 4011 can provide an initial buffering effect, and then the hard metal plate 4012 is not easily deformed, thereby ensuring the stability of the contact panel 401 when sliding.

[0048] Specifically, a pressure sensor is fixedly embedded on the upper surface of the pressure detection substrate 403 .

[0049] Furthermore, a pressure sensor of model GML670 is used. When the tool is pressed down, the pressure value detected by the pressure sensor will change, and the degree of pressure of the tool can be fed back based on the pressure value.

[0050] Working principle: When the lower tool holder is used, the base 1 is pressed against the shearing machine and fixed by bolts passing through the positioning opening 5. At this time, the stable support 6 is pressed against the shearing machine. At the same time, the difference in specifications between the upper plate 102 and the lower plate 101 is used to improve the stability of the base 1.

[0051] During the shearing process, the first type of knife groove 2 and the second type of knife groove 3 respectively provide activity space for the corresponding knife. When the knife gradually descends, the knife contacts the contact panel 401 in the knife deceleration assembly 4. As the knife gradually descends, the spring column 402 is compressed, and the pressure sensor in the pressure detection substrate 403 detects the pressure value. In this process, the arc notch 201 or the square notch 301 can balance the pressure environment on both sides of the contact panel 401. As the compression degree of the spring column 402 is different, the detection value of the pressure sensor is different, and the position of the knife is reflected by the difference in pressure value.

[0052] This allows the use of the lower tool holder.

[0053] It should be noted that, in this document, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
