DETAILED DESCRIPTION

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following describes a steel casting gate cutting device according to an embodiment of the present invention with reference to the accompanying drawings.

[0025] like Figure 1-Figure 5 As shown, the steel casting gate cutting device according to the embodiment of the present invention may include: a base 1, a lifting mechanism 2, a fixing mechanism 3, a vertical plate 4 and a cutting mechanism 5.

[0026] The lifting mechanism 2 is arranged on the base 1 .

[0027] It should be noted that the specific connection mechanism of the lifting mechanism 2 has been disclosed in the prior art and will not be described in detail here.

[0028] The fixing mechanism 3 is installed on the lifting mechanism 2 , and the vertical plate 4 is vertically arranged on the base 1 . An observation window 41 is provided on the vertical plate 4 .

[0029] The cutting mechanism 5 includes a horizontal plate 51, a driving assembly 52 and a cutting assembly 53, wherein the horizontal plate 51 is arranged on the vertical plate 4, the driving assembly 52 is installed on the horizontal plate 51, the driving end of the driving assembly 52 passes through the vertical plate 4, and the driving end of the driving assembly 52 extends to one side of the vertical plate 4, and the cutting assembly 53 is connected to the driving assembly 52.

[0030] Specifically, relevant technicians (for example, workers) cut the gates of a batch of steel castings. First, the steel castings are placed on a fixing mechanism 3, which can clamp the steel castings. Then, the lifting mechanism 2 is started, and the lifting mechanism 2 lifts the fixing mechanism 3 and the steel castings to the cutting assembly 53.

[0031] The cutting assembly 53 is running, and the worker is located on one side of the vertical plate 4. The driving end of the driving assembly 52 drives the driving assembly 52 to drive the cutting assembly 53 to move. The cutting assembly 53 moves along the driving assembly 52 to cut the gate of the steel casting. The cutting process is stable and reliable, thereby reducing the workload of subsequent processing steps.

[0032] During the cutting process, workers can observe the real-time cutting situation through the observation window 41. The observation window 41 can protect the workers and prevent the cutting waste from burning the workers. Until the cutting is completed, the lifting mechanism 2 is reset, and the fixing mechanism 3 releases the clamping of the steel casting. The worker can replace the next steel casting to be processed and repeat the above steps to complete the cutting of the gate of the next steel casting to be processed.

[0033] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the driving assembly 52 includes a hand wheel 521 , a worm gear transmission component 522 , two screws 523 , a plurality of base plates 524 and two second connecting blocks 525 .

[0034] Among them, the handwheel 521 is located on one side of the vertical plate 4, one end of the worm gear transmission component 522 passes through the vertical plate 4 and is rotatably connected to the vertical plate 4, one end of the worm gear transmission component 522 is connected to the handwheel 521, and the two screws 523 are respectively connected to the horizontal plate 51 through the corresponding base plates 524, the screws 523 are connected to the worm gear transmission component 522, and the two second connecting blocks 525 are respectively threadedly connected to the corresponding screws 523, and the second connecting block 525 is connected to the cutting assembly 53.

[0035] It should be noted that the worm gear transmission component 522 described in this embodiment includes two worm wheels and two worms, and the worm wheels are meshed and connected with the worms, thereby driving the screw 523 to rotate.

[0036] Specifically, the worker shakes the handwheel 521, the handwheel 521 drives the worm gear transmission component 522 to rotate, the worm gear transmission component 522 drives the screw 523 to rotate, the second connecting block 525 is threadedly connected to the screw 523, and the second connecting block 525 drives the cutting assembly 53 to operate.

[0037] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the cutting assembly 53 includes a second plate 531 , a frame 533 , a tightening knob 534 and a cutter 535 .

[0038] Among them, the second plate body 531 is connected to the second connecting block 525; two second through grooves 532 are symmetrically opened on the second plate body 531, the frame body 533 is slidingly connected to the second through grooves 532, the fastening knob 534 is installed on the frame body 533, one end of the fastening knob 534 is in conflict with the second plate body 531, and the cutter 535 is connected to the frame body 533.

[0039] It should be noted that the cutter 535 described in this embodiment includes a drive motor and a cutting grinding wheel. The drive motor drives the cutting grinding wheel to rotate, thereby cutting the gate of the steel casting.

[0040] Specifically, when the gate position of the steel casting to be processed is away from the cutter 535, the worker can loosen the fastening knob 534 to push the frame 533, and the frame 533 moves inside the second through groove 532. When the cutter 535 is close to the gate position of the steel casting to be processed, the worker rotates the fastening knob 534 again to fix the frame 533 on the second plate 531, thereby fixing the position of the cutter 535.

[0041] It is understandable that changing the position of the cutter 535 can expand the scope of application of the device.

[0042] In one embodiment of the present invention, Figure 1 and Figure 3As shown, the fixing mechanism 3 includes a first plate 31 , a base 33 , two telescopic rods 34 , two first connecting blocks 35 and two clamping blocks 36 .

[0043] Among them, the first plate body 31 is connected to the lifting mechanism 2, a first through slot 32 is opened on the first plate body 31, a base 33 is arranged on the lower surface of the first plate body 31, two telescopic rods 34 are respectively installed on the base 33, and two first connecting blocks 35 are respectively installed on the corresponding telescopic rods 34. The first connecting block 35 passes through the first through slot 32, and the first connecting block 35 is slidably connected to the first through slot 32. The two clamping blocks 36 are respectively connected to the corresponding first connecting blocks 35.

[0044] It should be noted that the telescopic rod 34 described in this embodiment can be a hydraulic telescopic rod. The telescopic rod 34 is connected to an external control device. During operation, the external control device sends an operation signal to the telescopic rod 34, and the telescopic rod 34 pulls the first connecting block 35 to move inside the first through groove 32. The first connecting block 35 drives the two clamping blocks 36 to move toward each other, thereby clamping the cast steel part.

[0045] As a possible situation, a buffer layer (not shown in the figure) may be bonded to the inner side wall of the clamping block 36 to prevent the clamping block 36 from scratching the outer wall of the steel casting.

[0046] As another possible situation, a pressure sensor (not shown in the figure) can be installed on the clamp block 36 to monitor the force applied by the clamp block 36 to the steel casting to avoid damage to the device or the steel casting itself due to excessive force, and unstable clamping due to insufficient force.

[0047] In one embodiment of the present invention, Figure 1 and Figure 5 As shown, the horizontal plate 51 is rotatably connected to the vertical plate 4 , and through holes 61 are respectively opened on the horizontal plate 51 and the vertical plate 4 , and rods 62 are inserted into the two through holes 61 .

[0048] It should be noted that the horizontal plate 51 and the vertical plate 4 are connected by a rotating shaft (not shown in the figure), which is located at a corner where the horizontal plate 51 and the vertical plate 4 overlap, and the through hole 61 and the insertion rod 62 are located at another corner where the horizontal plate 51 and the vertical plate 4 overlap.

[0049] Specifically, before placing the steel casting to be processed on the fixing mechanism 3, the worker can pull out the insertion rod 62 and then push the horizontal plate 51. The horizontal plate 51 rotates around the rotating shaft at a corner, thereby making room for the space above the fixing mechanism 3. After the steel casting is fixed, the horizontal plate 51 is positioned and the insertion rod 62 is inserted into the inside of the through hole 61, thereby connecting the horizontal plate 51 and the vertical plate 4.

[0050] In summary, the steel casting gate cutting device of the present invention provides an observation window on the vertical plate, so that workers can operate the driving assembly on one side of the vertical plate. The vertical plate can block the splashed cutting waste and play a protective role to avoid burns to workers. In addition, the driving assembly is used to drive the cutting assembly to move, and the fixing mechanism clamps the steel casting, thereby ensuring stability and reliability during the cutting process, thereby reducing the workload of subsequent processing steps.
