Description

Technical Field

[0001] The present invention relates to the technical field of cold shear blades. More specifically, the present invention is a cold shear blade for round steel with a flat end face. Background Art

[0002] According to the prior art patent with the application number: CN202021495404.X, a cold shear is a device used for cutting the head, tail, and sizing of rolled pieces coming off a cooling bed. The shear blade in the cold shear is the final actuator when the entire cold shear completes the shearing of rolled pieces. The cold shear equipment can not only shear ordinary profiles and wire rods, but also perform cold shearing operations on round steel. It includes a cutter frame, a fixed blade, and a movable blade. A shear notch is provided at the center of the cutter frame, and threaded positioning holes are provided on the wall surface of the cutter frame. A through groove is provided inside the cutter frame, and a fixed blade and a movable blade are assembled in the inner cavity of the through groove. The fixed blade is fixedly connected to the cutter frame, and the movable blade is movably connected to the cutter frame. A reset assembly is also installed in the inner cavity of the through groove, and the reset assembly includes a spring, a sleeve, and a vertical column.

[0003] However, in actual use, there are still some drawbacks. For example, when the existing cold shear shears round steel, the end face cut of the round steel is often uneven, and the cut is a beveled surface. Because the limiting effect of the shearing blade is not good, when the shearing blade contacts the top of the round steel and cuts downward, when the cutting force of the shearing blade is small, the blade will rebound repeatedly for a short distance after contacting the round steel, resulting in an uneven end face cut of the round steel and a triangular bevel cut of the round steel after cutting.

[0004] Therefore, in view of this, the inventor, with rich experience in design development and actual production in this related industry for many years, studies and improves the existing structure and deficiencies, and provides a cold shear blade for round steel with a flat end face, in order to achieve a more practical value. Summary of the Invention

[0005] To overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a cold shearing blade for round steel with a flat end face. By setting a limiting notch, a fixing round hole, and a limiting component, and using their mutual cooperation, first place the round steel bar inside the limiting notch, and make one side of it penetrate through the fixing round hole inside the mounting base. Then, use the electric telescopic rod to drive the fixed blade to cut the round steel. When the cutting force of the cutting edge of the shearing blade is small and the blade rebounds repeatedly for a short distance after contacting the round steel, make the limiting rotating side plate fit and contact with the side surface of the fixed rack plate, so that the limiting rotating side plate can use its special shape to limit the surface of the fixed rack plate, thereby ensuring that it can stretch and move the compression spring downward. When it rebounds in the reverse direction, the limiting rotating side plate is stuck with the fixed rack plate, thereby preventing it from bouncing up and ensuring the smoothness of the cutting section of the blade. By setting a fixing component and a mounting base, before cutting the round steel, the connecting column can drive the arc-shaped backing plate to move towards the top surface of the round steel and tightly contact with the round steel. Then, the limiting bent rod and the supporting cylinder are sequentially penetrated through the inside of the connecting column, and at the same time, the other end of the limiting bent rod passes through the inside of the mounting round hole, thereby ensuring the fixation of the connecting column and the arc-shaped backing plate at its bottom end, and thus ensuring that the round steel bar is in close contact with the arc-shaped backing plate, which can avoid the problems of rolling and sliding of the round steel bar during the cutting process, and thus avoid the bad situation of inclined sliding between the blade and the round steel bar, so as to solve the problems proposed in the above-mentioned background technology.

[0032] The limiting component 9 includes a fixed rack plate 91. The side surface of the fixed rack plate 91 is inlaid and installed with an installation side plate 92. The outer surface of the installation side plate 92 is threadedly connected with a fixed bolt 93. At the upper and lower ends of the outer surface of the installation side plate 92, matching screw ports 94 are opened;

[0033] A fixed connecting plate 95 is detachably inlaid inside the installation groove 11. On the top surface of one side of the fixed connecting plate 95, a support top plate 96 is inlaid and installed. A compression spring 97 is embedded at the bottom end of the support top plate 96. The side surface of the fixed connecting plate 95 is rotatably sleeved with a limiting rotating side plate 98;

[0034] A fixed rotating port 99 is opened on the surface of one side of the fixed connecting plate 95. A fixed slot hole 910 is opened inside the limiting rotating side plate 98. A fixed rotating shaft 911 is fixedly sleeved inside the fixed rotating port 99.

On the left and right sides of the top end of the transverse bottom plate 912, limiting side plates 913 are fixedly installed.

The other end of the connecting rod 918 is inlaid with an installation block 919.

[0036] Specifically refer to the attached drawings of the specification Figures 1-4 The other end of the installation block 919 is rotatably sleeved with a support side frame 920. The other end of the support side frame 920 is inlaid and connected with the inside of the fixed connecting plate 95. The limiting rotating side plate 98 is in close contact with the side surface of the fixed rack plate 91.

[0037] The implementation manner is specifically as follows: The limiting rotating side plate 98 is in close contact with the side surface of the fixed rack plate 91, so that the limiting rotating side plate 98 can use its special shape to limit the surface of the fixed rack plate 91, thereby ensuring that it can stretch and move the compression spring 97 downward. When bouncing back, the bottom end of the limiting rotating side plate 98 abuts against the fixed inclined panel 914 at its bottom end, and the limiting rotating side plate 98 is locked together with the fixed rack plate 91, thereby preventing it from bouncing up.

[0038] Specifically refer to the attached Figures 4-7 of the specification. The fixing component 10 includes a support plate 101. A connecting column 102 is movably sleeved on the surface of the support plate 101. The surface of the support plate 101 is successively provided with a fixing through hole 103 and a mounting round hole 104. An arc-shaped cushion plate 105 is inlaid and installed at the bottom end of the connecting column 102. A circular notch 106 is opened inside the connecting column 102. A buffer spring 107 is inlaid and installed at the top end of the arc-shaped cushion plate 105. A limiting bent rod 108 is detachably inlaid inside the support plate 101. A fixing cylinder 109 is embedded inside the connecting column 102.

[0039] The implementation manner is specifically as follows: Since the whole limiting bent rod 109 is made of alloy material, it has the advantages of several constituent metals, with higher mechanical strength, better corrosion resistance, lighter weight, harder texture, better toughness and fatigue resistance than single metal.

[0040] The working principle of the present invention:

[0041] The first step: First, the operator normally assembles each component of the device, and then normally starts the device.

[0042] Step 2: First, the operator places the round steel bar inside the limit notch 6, and makes one side of it penetrate out from the fixed round hole 7 inside the mounting base 2. Then, the electric telescopic rod 81 is used to drive the fixed blade 84 to cut the round steel. When the cutting force of the cutting edge of the shear blade is too small and the blade rebounds repeatedly for a short distance after contacting the round steel, the limit rotating side plate 98 is brought into close contact with the side surface of the fixed rack plate 91, so that the limit rotating side plate 98 can use its special shape to limit the surface of the fixed rack plate 91, thereby ensuring that it can stretch and move the compression spring 97 downward. When it rebounds in the reverse direction, the limit rotating side plate 98 is stuck with the fixed rack plate 91, thus preventing it from bouncing. At the same time, before cutting the round steel, the connecting column 102 can be driven to move the arc-shaped cushion plate 105 towards the top surface of the round steel and make tight contact with the round steel. Then, the limit bent rod 108 and the support cylinder 109 are sequentially passed through the inside of the connecting column 102, and at the same time, the other end of the limit bent rod 108 is passed through the inside of the mounting round hole 104, thereby ensuring the fixation of the connecting column 102 and the arc-shaped cushion plate 105 at its bottom end, and thus ensuring close contact between the round steel bar and the arc-shaped cushion plate 105, which can avoid the problems of rolling and sliding of the round steel bar during the cutting process, and further ensure the cutting work quality and effect of the device.

[0043] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixation between the various components of the device is normal. Then, the aging and severely worn parts inside the device are replaced and repaired.

[0044] In the above solution, by setting the fixing component and the mounting base, before cutting the round steel, the connecting column can be driven to move the arc-shaped cushion plate towards the top surface of the round steel and make tight contact with the round steel. Then, the limit bent rod and the support cylinder are sequentially passed through the inside of the connecting column, and at the same time, the other end of the limit bent rod is passed through the inside of the mounting round hole, thereby ensuring the fixation of the connecting column and the arc-shaped cushion plate at its bottom end, and thus ensuring close contact between the round steel bar and the arc-shaped cushion plate, which can avoid the problems of rolling and sliding of the round steel bar during the cutting process, and thus avoid the bad situation of inclined sliding between the blade and the round steel bar; by setting the rotating plate, the fixed block, the connecting rod, the mounting block, and the support side frame, through the mutual connection of several of them, the fixed inclined panel can be rotated and pulled out from the inside of the limit side plate on the horizontal bottom plate through the connecting rod. At this time, the fixed rack plate can be driven to move the fixed blade upward for reset, ensuring the safety of the device, and positioning and resetting for the next cutting operation, ensuring the working effect of the next cutting operation and the neatness of the cutting surface.
