[0002] The metal hot shearing process is to first place the metal part to be sheared in a hot shear heating furnace for heating, which reduces its hardness, increases its ductility, reduces its brittleness, thereby reducing the shear force and improving the shearing quality. The existing hot shearing process is mostly for shearing solid metal parts, and metal parts are usually made into various products, such as truck side bumpers formed by extrusion of aluminum bars. The extruded aluminum bumpers are hollow. When the hollow aluminum bumper is hot sheared, the heated aluminum bumper reduces its hardness and increases its ductility. Although this is conducive to shearing, it causes a pressure difference.

[0037] The adjacent edges of the upper and lower surfaces of the main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 are all set at an oblique angle; this facilitates the shearing knife 3 to squeeze between the main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603.

[0038] The support assembly also includes: a two-way pneumatic push rod 1 501 and a two-way pneumatic push rod 2 502; two two-way pneumatic push rods 1 501 are installed on each mounting rod 1 503; the two telescopic ends of each two-way pneumatic push rod 1 501 are respectively fixed to the adjacent mounting rod 2 504; two electric telescopic rods 3 604 are connected between each main support block 601 and the mounting rod 2 504; the main support block 601 is embedded in the adjacent mounting rod 2 504; all main support blocks 601, auxiliary support blocks 1 602 and auxiliary support blocks 2 603 are divided into upper and lower parts by the upper and lower central axes; two two-way pneumatic push rods 2 502 are commonly connected between the two mounting rods 1 503; the fixed part of the two-way pneumatic push rod 2 502 on one side is fixed to the telescopic end of the electric telescopic rod 2 4; the mounting rod 1 503 is hollow and serves as an air supply channel to the two-way pneumatic push rod 1 501 and the two-way pneumatic push rod 2 502 on the side away from the electric telescopic rod 2 4.

[0039] The use steps of the present invention are as follows:

[0040] by Figure 1 For reference, the mounting frame 2 is located on the left side, and the electric telescopic rod 2 4 is located on the right side. When the present invention is used, all electric components are powered.

[0041] When hot shearing the aluminum bumper, the extruded aluminum bumper is first placed in a hot shear heating furnace for heating (the hot shear heating furnace is a prior art and will not be elaborated on here). The conveyor belt 100 on the left side of the present invention is connected to the discharge port of the hot shear heating furnace, and the heated aluminum bumper is conveyed to the right through the conveyor belt 100 on the left side. The conveying is stopped after the required cutting position of the aluminum bumper is aligned with the shear knife 3. Then, the electric telescopic rod 202 is controlled to extend, and the mounting rod group 5 and the support mold 6 are pushed into the aluminum bumper so that the middle part of the support mold 6 is aligned with the cutting position of the shear knife 3 to provide internal support for the aluminum bumper. Then, the upper and lower electric telescopic rods 202 are controlled to extend, and the shear knife 3 is pushed to shear the aluminum bumper in the upper and lower directions until the shear knife 3 cuts through the aluminum bumper and contacts the surface of the support mold 6. Then, the upper and lower electric telescopic rods 202 are controlled to contract to drive the corresponding shear knife 3 reset; then control the front and rear electric telescopic rods 202 to extend, drive the corresponding shearing knife 3 to shear the aluminum bumper in the front and rear directions until the aluminum bumper is cut through, completing the comprehensive cutting of the aluminum bumper; then control the front and rear electric telescopic rods 202 to retract, drive the corresponding shearing knife 3 to reset, and then control the electric telescopic rod 2 4 to retract, pull the mounting rod group 5 and the supporting mold 6 out of the aluminum bumper to the right, and the cut part of the aluminum bumper is located on the conveyor belt 100 on the right, and its right side is limited by the grinding wheel 8. When the mounting rod group 5 and the supporting mold 6 are about to separate from the cut aluminum bumper, control the electric slider 2 105 to move to the right along the guide rail 2 104, drive the grinding assembly to move to the right, separate from the right side of the aluminum bumper, and the mounting rod group 5 and the supporting mold 6 are separated from the aluminum bumper. Then, with the help of a manipulator, the cut aluminum bumper can be removed from the conveyor belt 100 on the right.

[0042] When continuing to cut the remaining aluminum bumper on the left side, first move the aluminum bumper to the right. After moving to the right to the appropriate cutting length, the mounting rod group 5 and the supporting mold 6 enter the aluminum bumper, and control the electric telescopic rod 2 4 to extend and move the mounting rod group 5 and the supporting mold 6 to the left to the cutting position. After supporting the aluminum bumper, the section on the right side that was cut last time will contact the left side of the grinding wheel 8. At this time, the control motor 107 drives the driving wheel 7 to rotate, and the driving wheel 7 drives the grinding wheel 8 to rotate. The left side of the grinding wheel 8 grinds the section. After that, the grinding wheel 8 is paused from rotating, and the control The electric slider 2 105 moves to the right, so that the grinding wheel 8 is separated from the right section of the aluminum bumper, and then the electric telescopic rod 4 801 is controlled to retract, driving the mounting frame 802 and the coating roller 803 to move to the left, and the coating roller 803 protrudes from the left side of the grinding wheel 8. Then the grinding wheel 8 is controlled to rotate, and the grinding wheel 8 drives the anti-oxidation component to rotate, and the coating roller 803 contacts the cross section of the aluminum bumper. Then the grinding wheel 8 is controlled to rotate again, and the coating roller 803 rotates synchronously, and the antioxidant coating is fully coated on the cross section of the aluminum bumper for anti-oxidation treatment; then the shearing work is continued.

[0043] When the aluminum bumper is beveled, the two electric sliders 102 are controlled to move oppositely along the corresponding guide rail 101. The electric slider 102 drives the corresponding connecting shaft 103 and the connecting block 201 to move. The two connecting blocks 201 moving oppositely push the front and rear sides of the mounting frame 2 respectively, so that the mounting frame 2 rotates 45 degrees with the rotation connection point with the frame 1 as the center. The electric telescopic rod 202 and the shearing knife 3 on the mounting frame 2 also rotate 45 degrees. Then, the upper and lower shearing knives 3 are controlled to cut the aluminum bumper first. After cutting through the upper and lower surfaces of the aluminum bumper, the shearing knife 3 continues to penetrate, such as Figure 7 As shown, the shearing knife 3 is inserted between the main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603, and at the same time the electric telescopic rod 3 604 contracts, driving the main support block 601 on the left to move to the left, and the main support block 601 on the right to move to the right, and the shearing knife 3 is squeezed into the corresponding main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603, and the corresponding main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 are separated by the oblique shearing line of the shearing knife 3 until the shearing knife 3 is close to the mounting rod group 5 to complete the upper and lower shearing work. , then control the upper and lower shear blades 3 to reset, at this time the electric telescopic rod three 604 remains retracted, and there is still a gap between the main support block 601, the auxiliary support block one 602 and the auxiliary support block two 603 separated by the upper and lower shear blades 3, and then control the front and rear shear blades 3 to shear the aluminum bumper, and the front and rear shear blades 3 cut through the aluminum bumper at an oblique angle and squeeze into the gap m between the main support block 601, the auxiliary support block one 602 and the auxiliary support block two 603, cutting through the front and rear side walls of the aluminum bumper, thereby performing oblique shearing on the aluminum bumper to form an oblique incision.

[0044] For aluminum bumpers with larger internal space, after the mounting rod group 5 and the supporting mold 6 are extended therein, air is supplied to the two-way pneumatic push rod 1 501 and the two-way pneumatic push rod 2 502 simultaneously. The two-way pneumatic push rod 1 501 extends to push the front and rear mounting rod groups 5 away from the middle mounting rod group 5. The front mounting rod group 5 drives the auxiliary support block 1 602 to move forward, and the rear mounting rod group 5 drives the auxiliary support block 2 603 to move backward, thereby expanding the front and rear support areas of the supporting mold 6 to adapt to the front and rear length of the interior of the aluminum bumper; and the two-way pneumatic push rod 2 502 extends out, driving the two corresponding mounting rod groups 5 on the upper and lower sides to move away from each other, and the mounting rod group 5 on the upper side drives all the main support blocks 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 above the central axis to move upward, and the mounting rod group 5 on the lower side drives all the main support blocks 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 above the central axis to move downward, thereby expanding the upper and lower heights of the support mold 6 to adapt to the upper and lower heights inside the aluminum bumper; thereby, the support mold 6 supports the aluminum bumper with a larger internal space.

[0045] It should be noted that the height of the frame 1 can be manually adjusted so that the mounting rod set 5 and the supporting mold 6 are aligned with the middle of the aluminum bumper, so that the mounting rod set 5 and the supporting mold 6 can smoothly enter the aluminum bumper.

[0046] According to the above steps, we know that the present invention has the following effects:

[0047] When a hollow aluminum bumper formed by extruding an aluminum rod is subjected to hot shearing, the heated aluminum bumper has reduced hardness and increased ductility, which is beneficial for shearing. However, the shearing force applied from the outside to the inside during shearing can easily cause the hollow aluminum bumper to sag inward, affecting the shearing quality. The present invention extends the support mold 6 into the hollow aluminum bumper to provide internal support, thereby preventing the hollow aluminum bumper from being deformed inward due to the shearing pressure during shearing, thereby affecting the shearing quality.

[0048] When the aluminum bumper is beveled, the control mounting frame 2 drives the electric telescopic rod 202 and the shearing knife 3 to rotate to form an angle cutting position. At the same time, the supporting mold 6 composed of multiple main support blocks 601, auxiliary support block 1 602 and auxiliary support block 2 603 supports the inside of the aluminum bumper. The upper and lower shearing knives 3 first cut through and penetrate into the aluminum bumper. The shearing knife 3 will squeeze into the corresponding main support block 601, auxiliary support block 1 602 and auxiliary support block 2 603. The corresponding main support block 601, auxiliary support block 1 602 and auxiliary support block 2 603 are separated with the shearing line of the shearing knife 3 as the boundary to avoid the shearing knife 3, and then the front and rear shearing knives 3 perform bevel cutting. The required shearing parts are less than the upper and lower shearing parts, reducing the poor cutting quality caused by the cutting angle of the front and rear shearing knives 3.

[0049] Usually, aluminum bumpers come in different sizes, and the internal space of aluminum bumpers of different sizes will fluctuate on the centimeter level. For aluminum bumpers with larger internal space, the fixed-size support mold 6 cannot adapt to its internal space and cannot provide support. Therefore, by controlling the two-way pneumatic push rod 1 501 and the two-way pneumatic push rod 2 502 to extend, the main support blocks 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 are separated, and the front and rear support areas and the upper and lower heights of the support mold 6 are expanded, so that the support mold 6 can adapt to aluminum bumpers with larger internal space and support aluminum bumpers with larger internal space, thereby improving the scope of application of the present invention.

[0050] The additional technical effects of the present invention are as follows:

[0051] like Figure 4 As shown, the adjacent edges of the upper and lower surfaces of the main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 are all set at an oblique angle; when the shearing knife 3 shears, it is convenient to squeeze into between the main support block 601, the auxiliary support block 1 602 and the auxiliary support block 2 603 to increase the shearing depth.

[0052] Example 2: Based on Example 1, Figure 4 and 6 - Figure 8 As shown, it also includes a shaping frame 9; the shaping frame 9 is connected to the side of the supporting mold 6 facing the aluminum bumper; the shaping frame 9 is composed of six shaping blocks 901; each shaping block 901 is fixedly connected to the adjacent main support block 601, auxiliary support block 1 602 and auxiliary support block 2 603 respectively.

[0053] The side of each shaping block 901 facing the aluminum bumper is arranged in an oblique angle, so that the shaping frame 9 as a whole can smoothly enter the aluminum bumper.

[0054] A pressure monitor is provided on the electric telescopic rod 2 4 ; it is used to monitor the pressure of the electric telescopic rod 2 4 when it is extended in real time, and to know whether the extension of the electric telescopic rod 2 4 is blocked.

[0055] The operating steps of this embodiment are as follows:

[0056] When the mounting rod group 5 and the supporting mold 6 are extended into the interior of the aluminum bumper, the shaping frame 9 enters the aluminum bumper before the supporting mold 6. When there is local deformation inside the aluminum bumper due to uneven heating, the shaping frame 9 will contact the deformed part before the supporting mold 6, squeeze the deformed part to restore it, and the shaping frame 9 can continue to extend into the aluminum bumper smoothly, and the mounting rod group 5 and the supporting mold 6 can also continue to extend. When the shaping frame 9 is unable to be squeezed to restore it, the shaping frame 9 is blocked and cannot continue to move. At this time, the pressure monitor on the electric telescopic rod 2 4 detects that the extension pressure of the electric telescopic rod 2 4 is abnormal, and warns the worker that the mounting rod group 5, the supporting mold 6 and the shaping frame 9 cannot continue to extend into the aluminum bumper, and the operation should be stopped immediately, so that the mounting rod group 5, the supporting mold 6 and the shaping frame 9 are withdrawn from the aluminum bumper, and other means are used to repair the internally deformed aluminum bumper.

[0057] According to the above steps, we know that the present invention also has the following effects:

[0058] The shaping frame 9 enters the aluminum bumper before the supporting mold 6, and the local deformation in the aluminum bumper is squeezed and restored, so that the installation rod group 5, the supporting mold 6 and the shaping frame 9 can be smoothly extended into the aluminum bumper, avoiding damage to the supporting mold 6 with higher structural precision and higher production cost; and when encountering a deformation situation that the shaping frame 9 cannot be squeezed to restore it, the pressure monitor of the electric telescopic rod 2 4 detects abnormal pressure, and promptly warns the workers to stop installing the rod group 5, the supporting mold 6 and the shaping frame 9 from extending into the aluminum bumper, avoiding damage to the electric telescopic rod 2 4, the installation rod group 5, the supporting mold 6 and the shaping frame 9.

[0059] The additional technical effects of this embodiment are as follows:

[0060] like Figure 8 As shown, the shaping frame 9 is composed of six shaping blocks 901. When it is necessary to adapt to a larger-sized aluminum bumper for support, the main support block 601, auxiliary support block 1 602 and auxiliary support block 2 603 of the support mold 6 expand with each other, and at the same time, the six shaping blocks 901 move with the corresponding main support block 601, auxiliary support block 1 602 or auxiliary support block 2 603 to avoid hindering the expansion of the support mold 6 and adapting to a larger-sized aluminum bumper.

[0061] Although the present disclosure has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-described embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
