Embodiment
[0028] The embodiment provides a reinforced non-standard trench cutter 100, which comprises a cutter bar 110 and a cutter blade 120. Figure 1 As shown, the machining process needs to be turned on the bottom of the disc. The outer diameter of the disc is 98mm, and the turning depth is 16mm. The rough turning allowance is large at this position, and the cutting resistance is large.
[0029] AsFigure 2 As shown in the drawings, the bottom of the tool bar 110 has a vertically arranged assembly surface 111, the blade 120 includes a mounting plate 121 and a cutting edge 122, the mounting plate 121 is attached to the assembly surface 111, the mounting plate 121 has a first mounting hole, and is fixed to the assembly surface 111 by a first locking screw 1211 passing through the first mounting hole; the cutting edge 122 is located at the bottom of the mounting plate 121 and extends outwardly from the assembly surface 111; the cutting edge 122 has a vertically arranged cutting surface 1221, which is perpendicular to the assembly surface 111. During the cutting process, because the cutting surface 1221 is outside the mounting plane, the cutting edge 122 generates a torque during the force process, which on the one hand causes the mounting plate 121 to rotate in the assembly surface 111 with the first locking screw 1211 as the shaft (in the direction of the arrow in Figure 3 ), and on the other hand causes the mounting plate 121 to overturn outwardly from the assembly surface 111 with the side away from the cutting surface 1221 as the shaft (in the direction of the arrow in Figure 4 ), resulting in the blade 120 being very easy to break.
[0030] In view of this, as shown in Figure 2 and Figure 3 , the embodiment is provided with a pressing plate 123 on the mounting plate 121, the pressing plate 123 extends from one side of the mounting plate 121 towards the direction facing the cutting surface 1221 and beyond the cutting surface 1221; the pressing plate has a second mounting hole, and cooperates with the assembly surface 111 by a second locking screw 1231 passing through the second mounting hole. The position of the pressing plate 123 is located in the lower position of the mounting plate 121, above the cutting edge 122, and the generated tension can limit the rotation of the mounting plate 121 in the assembly surface 111 and the overturning of the mounting plate 121 outwardly from the assembly surface 111, effectively improving the rigidity of the blade 120 and prolonging the service life of the blade 120.
[0031] As shown in Figure 2 and Figure 5 , the assembly surface 111 is recessed inwardly to form an assembly groove 112, the shape of the assembly groove 112 matches the mounting plate 121, and the depth of the assembly groove 112 is comparable to the thickness of the mounting plate 121. The assembly groove 112 can limit the mounting plate 121 by its groove wall, further limiting its overturning, and at the same time, the mounting plate 121 can be hidden below the assembly surface 111 to prevent it from interfering with the cutting process.
[0032] The assembly surface 111 is also provided with an extension groove 113, the shape of the extension groove 113 matches the pressing plate 123, and the depth of the extension groove 113 is greater than the thickness of the pressing plate 123. The thickness of the pressing plate 123 gradually decreases away from the mounting plate 121. The obliquely arranged pressing plate 123 forms a stronger tension, which can better limit the overturning of the mounting plate 121.
[0033] Further, the assembly groove 112 is provided with an inclined first supporting surface 1121 on the side away from the cutting surface 1221, which gradually moves away from the cutting surface 1221 along the upward direction. The top of the assembly groove 112 is provided with a second supporting surface 1122, which is parallel to the first supporting surface 1121 and is centrally symmetric with the geometric center of the assembly groove 112 as the center point. The first supporting surface 1121 and the second supporting surface 1122 can provide more powerful support on the upper and lower sides of the mounting plate 121, and better limit the rotation of the mounting plate 121 in the assembly groove 112.
[0034] As shown in Figure 2 and Figure 5 The knife bar 110 is provided with a step 114 protruding from the assembly surface 111 above the assembly surface 111, and the bottom of the step 114 is provided with a limiting groove 115. The top of the mounting plate is provided with a limiting block 124, which extends outward from the assembly surface 111 and is embedded in the limiting groove 115. The length of the limiting block 124 and the outward extension of the cutting edge 122 is equivalent. The limiting block 124 balances the torque generated during the cutting process of the cutting edge 122 from above, and better maintains the stability of the blade 120.
[0035] In summary, the utility model embodiment provides a reinforced non-standard trench knife 100, which comprises a knife bar 110 and a blade 120, the bottom of the knife bar 110 is provided with a vertically arranged assembly surface 111, the blade 120 comprises a mounting plate 121 and a cutting edge 122, the mounting plate 121 is provided with a pressing plate 123, the pressing plate 123 extends from one side of the mounting plate 121 towards the direction faced by the cutting surface 1221 and exceeds the cutting surface 1221; the pressing plate has a second mounting hole penetrating through, and is matched with the assembly surface 111 through a second locking screw 1231 penetrating through the second mounting hole. The pressing plate 123 forms a new fixed point in front of the cutting surface 1221, thereby offsetting the torque generated in the chip processing process, improving the rigidity of the blade 120, reducing the tool vibration in the cutting process, improving the tool life, and reducing the tool cost.
