Technical fields:

[0001] The utility model belongs to the field of mining truck stone slab production, and particularly relates to the cutting head mold for mining truck stone slab production. Background technology:

[0002] Mining trucks primarily operate within mining areas. Their rear wheels are typically dual-wheel configurations. Because mining areas generally have uneven surfaces and contain numerous rocks, rocks often accidentally get stuck between the two rear tires. If these rocks are not removed promptly, they will continuously compress and wear down the inner side of the tire, eventually leading to tire rupture. Therefore, it is necessary to install rock-removal plates on mining trucks to promptly remove rocks trapped in the tire grooves.

[0003] Stone slabs are long, strip-shaped metal pieces. During production, both ends need to be machined into arc shapes. Current technology typically uses milling, which is time-consuming, inefficient, and costly. Therefore, there is an urgent need to develop a mold for cutting the ends of stone slabs, ensuring that the slabs can be machined with arc-shaped ends and that their shape meets usage requirements.

Detailed implementation method:

[0019] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0020] like Figures 1 to 5 As shown, a cutting head mold for producing stone slabs for mining trucks is characterized by comprising an upper mold base 1 and a lower mold base 2. A mold handle 101 is installed on the top wall of the upper mold base 1, an upper blade holder 102 is installed on the bottom wall of the upper mold base 1, an upper blade 103 is installed on the upper blade holder 102, and guide sleeves 104 are provided at both ends of the upper blade holder 102.

A hinge seat 302 is slidably connected within the through-hole 301. A pressure plate 303 is hinged to the hinge seat 302. A spring 304 is installed on the top wall of the hinge seat 302, and the top end of the spring 304 is fixedly connected to the bottom wall of the upper mold base 1. The material support assembly includes a material support plate 4, the end of which is fixedly connected to the top wall of the lower mold base 2. The material support plate 4 is located behind the lower cutter holder 202, and the top wall of the material support plate 4 is fixedly connected to the bottom wall of the lower cutter holder 202. The top wall is on the same plane. A through groove 401 is provided on the material support plate 4 along the length direction. A slider 402 is slidably connected in the through groove 401. A positioning block 403 and an anti-detachment piece 404 are respectively provided at the top and bottom of the slider 402. The slider 402, the positioning block 403 and the anti-detachment piece 404 are fixedly connected by a first bolt 405. A right-angle groove 406 and an arc-shaped groove 407 are respectively provided at both ends of the positioning block 403.

[0021] Specifically, by using a cutting die, both ends of the stone slab workpiece 9 can be quickly cut into an arc shape.

[0022] In actual use, firstly, connect the mold handle 101 to the press, so that the upper mold base 1 can be connected to the press module. Then, install the lower mold base 2 on the press's processing table. The mold installation method is common knowledge known to those skilled in the art and will not be elaborated here. At this time, several stone-discharging slab workpieces 9 can be neatly placed on the material support assembly, and one end of the stone-discharging slab workpiece 9 can be inserted between the upper mold base 1 and the lower mold base 2. Then, start the press to drive the upper mold base 1 to descend, and guide post 201... Guided by the guide sleeve 104, the upper cutter 103 slides, causing its arc-shaped concave cutting surface to cut the end of the stone-laying slab workpiece 9. When the arc-shaped concave cutting surface of the upper cutter 103 engages with the arc-shaped convex cutting surface of the lower cutter 203, the arc-shaped cutting operation of the end of the stone-laying slab workpiece 9 is completed. During the cutting process, both ends of the stone-laying slab workpiece 9 need to be heated to further facilitate the rapid cutting and shaping of its arc-shaped ends. After the arc-shaped cutting of both ends of the stone-laying slab workpiece 9 is completed, it is sent to the subsequent process for end drilling.

[0023] During the above processing, when the press drives the upper mold base 1 to descend, the pressure plate 303 presses the stone-removing plate workpiece 9 to prevent it from shifting during the cutting process, thereby ensuring the safety and stability of the cutting process. Specifically, when the pressure plate 303 presses down on the stone-removing plate workpiece 9, the hinge seat 302 slides into the through 301 and gradually compresses the spring 304, so that the pressure plate 303 can always elastically press the stone-removing plate workpiece 9 during the cutting process, avoiding hard mechanical damage.

[0024] When the stone slab workpiece 9 is placed on the support plate 4, the positioning block 403 can be dragged and slid on the through groove 401, and the right-angled groove 406 end of the positioning block 403 is aligned with the uncut end of the stone slab workpiece 9. At this time, the first bolt 405 is tightened so that the position of the positioning block 403 can be fixed on the support plate 4. Under the action of the positioning block 403, the stone slab workpiece 9 can be further prevented from shifting during cutting, and it is also convenient for workers to measure the size of the stone slab workpiece 9 more stably. After one end of the stone slab workpiece 9 has been cut into an arc shape, the first bolt 405 can be loosened, the two ends of the stone slab workpiece 9 can be swapped, and the positioning block 403 can be rotated so that the cut arc end of the stone slab workpiece 9 can be aligned with the arc groove 407, thereby further facilitating the stable arc cutting operation of the other end of the stone slab workpiece 9.

[0025] like Figures 1 to 5As shown, the cutting head mold for producing stone slabs for mining trucks has a right-angled trapezoidal boss at the inner end of the lower cutter seat 202. The lower cutter 203 is mounted on the right-angled trapezoidal boss. A pair of adjustment holes 5 are provided on the lower cutter 203, and a second bolt 501 is installed in the adjustment holes 5. The lower cutter seat 202 and the lower cutter 203 are fixedly connected by the second bolt 501. A gap adjustment block 502 is provided in the gap between the lower cutter 203 and the right-angled trapezoidal boss. A pair of guide seats 6 are installed on the lower mold base 2. Wear-resistant plates 7 are installed on the inner side wall of the guide seats 6 and the outer side wall of the upper cutter seat 102. A notch 8 is provided on the lower mold base 2, and the notch 8 is located between the two guide seats 6. The inner side wall of the notch 8 is inclined.

[0026] Specifically, the position of the lower cutter 203 on the lower cutter holder 202 can be finely adjusted through the adjustment hole 5.

[0027] In actual use, mechanical wear will inevitably occur after the mold has been used for a long time. At this time, the second bolt 501 can be loosened. Under the action of the adjusting hole 5, the position of the gap adjusting block 502 in the gap between the lower cutter 203 and the right-angled trapezoidal boss can be adjusted. After the position of the lower cutter 203 is determined, the second bolt 501 is tightened to further ensure the precise matching of the upper and lower cutters, avoid dimensional deviations caused by processing errors or wear, and ensure the dimensional stability and surface quality of the stone-laying plate workpiece 9. When the upper cutter 103 cuts the stone-laying plate workpiece 9, it will generate a directional... The force behind the upper cutter 103 causes it to move slightly backward. After prolonged use, this can easily cause wear on the surfaces of the guide sleeve 104 and the guide post 201. Therefore, a pair of guide seats 6 installed on the lower mold base 2 can prevent the upper cutter 103 from moving backward during cutting, protecting the guide sleeve 104 and the guide post 201 from wear. The wear-resistant plate 7 can reduce the direct hard contact between the upper cutter 103 and the guide seat 6, extending their service life. The broken end of the stone slab workpiece 9 can be quickly slid out of the mold through the notch 8 opened on the guide seat 6, making it easy for workers to clean and recycle it in time.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
