Description

Technical Field

[0001] The invention relates to a casting body cutting machine, in particular to an automatic cutting device. Background Art

[0002] When the casting is completed, the casting body presents a structure in which multiple casting bodies are connected to one or more sides of the runner. The casting body needs to be cut off from the runner to obtain the casting body. The traditional cutting method is manual cutting, where the staff holds the workpiece and sends it to the high-speed saw blade to cut the connection between the runner and the casting body to make the casting body fall off. This traditional method is prone to danger and inefficient. The existing automated cutting equipment fixes the workpiece with a clamp, and uses a high-speed saw blade to cut one side of the workpiece to obtain the casting body. This method requires removing the workpiece after cutting one side each time, replacing the other side, and then fixing it with a clamp. The overall efficiency is not high. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an automatic cutting device that can improve the cutting efficiency of the casting body.

[0004] The automatic cutting equipment according to the embodiment of the present invention includes a frame, a movable frame, which can be movably connected to the frame up and down, and a support base is arranged on the movable frame; two rotating shafts are arranged on the frame and are respectively located on the left and right sides of the support base; two groups of saw blade units are respectively fixed on the two rotating shafts, and each group of the saw blade units is provided with two saw blades, and the two saw blades are arranged at intervals and connected to the rotating shaft, and are respectively located on the front and back sides of the support base; a first driving mechanism is arranged on the frame, connected to the two rotating shafts, and can drive the two rotating shafts to rotate; a second driving mechanism is arranged on the frame and can drive the movable frame to move up and down; a clamping mechanism is arranged on the movable frame and is located above the support base.

[0005] According to the automatic cutting equipment of the embodiment of the present invention, at least the following beneficial effects are achieved: the workpiece can be pressed and fixed on the sliding frame by the clamping device and the supporting seat, and the two saw blades of the two saw blade units are driven by the first driving mechanism to rotate to cut the workpiece, and the workpiece on the movable frame is driven by the second driving mechanism to approach the two saw blades, so that the casting body located on the front and rear sides of the workpiece can be separated from the runner on the workpiece during one cutting process, thereby improving the efficiency of workpiece cutting; and by providing the two rotating shafts and the saw blade units provided on the two rotating shafts, cutting is performed from the left and right sides of the workpiece, so that the force on the workpiece can be more evenly applied, thereby avoiding the problem of positional displacement of the workpiece due to unilateral force, thereby affecting the cutting accuracy.

[0006] According to an embodiment of the present invention, a positioning mechanism is included, and the positioning mechanism is arranged on the frame and located behind the movable frame. The positioning mechanism pushes the workpiece so that the runner of the workpiece can be aligned with the clamping mechanism and the support seat, thereby improving the alignment accuracy.

[0007] According to an embodiment of the present invention, the movable frame is provided with a rack structure extending up and down, the second driving mechanism includes a gear and a second motor driving the gear to rotate, and the gear is meshed with the rack structure. The second motor drives the gear to rotate, so that the movable frame with the rack structure can move up and down and approach the saw blade unit. The meshing of the rack structure and the transmission teeth provides a stable feed amount when the workpiece is cut, so that the workpiece is evenly stressed and it is not easy to break the connection between the casting body and the runner.

[0008] According to an embodiment of the present invention, the movable frame includes a base plate, a crossbeam, a left column and a right column; the crossbeam is located directly above the base plate; the support seat is arranged in the middle of the base plate, wherein the left column connects the left end of the base plate and the left end of the crossbeam, and the right column connects the right end of the base plate and the right end of the crossbeam; the movable frame stably fixes the position of the support seat and the clamping mechanism, so that the workpiece is not easy to shake during the cutting process, thereby improving the cutting accuracy.

[0009] According to an embodiment of the present invention, the first driving mechanism includes two first motors and two sets of transmission belts; the two first motors are connected to the two rotating shafts through the two sets of transmission belts. By arranging two motors to drive the two rotating shafts to rotate respectively, the rotation of the two rotating shafts can be controlled separately, and when necessary, only one of the rotating shafts can be driven to rotate.

[0010] According to an embodiment of the present invention, the clamping mechanism includes a clamping block and a third driving mechanism for driving the clamping block to move up and down, a clamping slot is provided at the lower end of the clamping block, a support block is provided on the support seat, a groove is provided at the top of the support block, and the clamping block is located directly above the support block. The clamping slot at the lower end of the clamping block and the groove provided at the top of the support block can respectively fix the upper runner and the lower runner of the workpiece, reduce the displacement of the workpiece, reduce shaking, and better achieve clamping and fixing.

When the workpiece is embedded in the slot on the pressure strip, the pressing block can drive the workpiece to rotate, thereby realizing the automatic face-changing function of the workpiece without re-clamping the workpiece; for example, when the casting body on the workpiece is not only arranged on the front and rear sides of the workpiece runner, but the front, rear, left and right sides of the runner all have casting bodies, after cutting the casting bodies on the front and rear sides of the workpiece, the workpiece is driven to rotate by the fourth driving mechanism, so that the workpieces on the left and right sides of the workpiece can be directly cut without removing the workpiece from the movable frame, rotating it and clamping it again.

[0012] According to an embodiment of the present invention, the fourth driving mechanism is a second cylinder, one end of the cylinder body of the second cylinder is hinged to the lifting platform, and the piston rod of the second cylinder is hinged to the pressure block. The cylinder can provide uniform and stable power output, and can achieve reciprocating motion, thereby improving the overall stability of the device. The back and forth movement of the piston rod of the second cylinder can rotate the pressure block hinged to the piston rod, thereby allowing the workpiece to rotate a certain angle.

[0013] According to an embodiment of the present invention, two pressure strips are arranged at intervals at the lower end of the pressure block, and the clamping groove is arranged at the lower end of the pressure strip. The two pressure strips arranged at intervals can enable the pressure block to press the two sides of the runner or pouring port at the upper end of the workpiece, thereby improving the positioning accuracy of the pressing and fixing.

[0014] According to an embodiment of the present invention, a material drop chute is further included, which is obliquely arranged on both sides of the support seat and is located below the saw blade unit. When the casting body on the workpiece is cut by the saw blade, it will fall into the material drop chute and will not scatter around, thereby improving the collection efficiency of the casting body.

[0051] In this embodiment, if Figure 5 As shown, the clamping mechanism 600 includes a clamping block 630 and a third driving mechanism 610 for driving the clamping block 630 to move up and down. The lower end of the clamping block 630 is provided with two pressure strips 631 spaced apart, and the lower end of the pressure strip 631 is provided with a slot 632.

When the casting body on the workpiece is cut by the saw blade 410, it will fall into the material drop chute 300 and will not scatter around, thereby improving the collection efficiency of the casting body.

[0054] The following describes in detail the workflow of the automatic cutting device according to this embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0055] First, the control unit 200 is used to control the movable frame 500 to rise until the support seat 560 is higher than the top of the two saw blades 410, so that the movable frame 500 is in the initial state, which is convenient for the staff to safely disassemble and install the workpiece; then the staff installs the lower runner of the workpiece on the two raised grooves 562 on the support block 561, and the staff controls the positioning mechanism 700 to move forward to support the runner of the workpiece and push the workpiece to align with the groove 632 of the pressure strip 631, and controls the clamping mechanism 600 to move downward through the control unit 200, so that the groove 632 on the pressure strip 631 under the pressure block 630 is aligned with the top of the workpiece. After the workpiece is fixed, the first drive mechanism 800 drives the rotating shaft 820 to rotate, thereby driving the saw blade unit 400 to rotate; when the saw blade unit 400 reaches a certain speed, the movable frame 500 drives the workpiece to move downward so that the two sides of the workpiece are close to the two saw blades 410 for cutting. When the workpiece needs to be cut on multiple sides, the movable frame 500 can be raised after the saw blade 410 completes a cut so that the support seat 560 is higher than the saw blade unit 400, and then the workpiece face change operation is completed through manual operation by the staff, and then the movable frame 500 is lowered to continue cutting the workpiece. After the cutting is completed, the movable frame 500 is reset to the initial state, and the staff disassembles the workpiece to carry out the next round of cutting cycle.

[0056] The automatic cutting equipment according to the first embodiment of the present invention can achieve at least the following effects by being configured in this way: the first driving mechanism 800 drives the two saw blades 410 of the two saw blade units 400 to rotate to cut the workpiece, and the second driving mechanism 830 drives the workpiece on the movable frame close to the two saw blades 410 so that the workpiece can be cut on both sides simultaneously during one casting cutting process, and the casting body located on the front and rear sides of the workpiece can be separated from the runner on the workpiece during one cutting process, thereby improving the efficiency of workpiece cutting.

[0057] Embodiment 2:

[0058] Reference below Figures 7 to 9 The automatic cutting device according to the second embodiment of the present invention is described. The difference between the second embodiment and the first embodiment is that the clamping mechanism 600 and the support block 561 are configured to drive the workpiece to rotate, and the remaining structures are the same as those of the first embodiment.

[0059] like Figure 7 As shown, in this embodiment, the clamping mechanism 600 also includes a lifting platform 640, the pressing block 630 is rotatably connected to the lifting platform 640, and a fourth driving mechanism 620 for driving the pressing block 630 to rotate is arranged on the lifting platform 640. The third driving mechanism 610 is connected to the lifting platform 640 and can drive the lifting platform 640 to move up and down. The pressing block 630 is connected to the fourth driving mechanism 620 and can be driven by the fourth driving mechanism 620 to realize the rotation of the pressing block 630.

[0060] like Figure 8 As shown, the card slot 632 is arranged on both sides of the pressure strip 631 and is provided with notches, such as Fig. 9 As shown, the runner or pouring channel of the workpiece is provided with protrusions 633 on the left and right, and the protrusions 633 can be engaged with the clamping groove 632 through the notch of the clamping groove 632, so that the pressure strip 631 can clamp the workpiece. The single groove 562 on the top of the support block 561 is a spherical groove or a square groove. When the end of the lower runner of the workpiece is set to a spherical shape, the runner of the workpiece can achieve surface contact with the spherical groove of the groove 562 and can keep rotating, or the square groove of the groove 562 can achieve point contact with the spherical end of the runner of the workpiece and can keep rotating. When the upper and lower runners of the workpiece are respectively embedded in the clamping groove 632 on the pressure strip 631 and the groove 562 on the top of the support block 561, the pressure block 630 can drive the workpiece to rotate, realizing the function of automatic face changing.

[0061] Of course, according to actual conditions, in some other embodiments, the support block 561 may be rotatably connected to the support seat 560 to achieve rotation of the workpiece.

[0062] In this embodiment, if Figure 8 As shown, the fourth driving mechanism 620 is a second cylinder 621, one end of the cylinder body of the second cylinder 621 is hinged to the lifting platform 640, the piston rod 622 of the second cylinder 621 is hinged to the pressure block 630, and the pressure block 630 is rotatably connected to the lifting platform 640. In order to facilitate the control of the second cylinder 621 by the control unit 200, a second solenoid valve is also included. The control unit 200 is electrically connected to the second solenoid valve and controls the second cylinder 621 through the second solenoid valve. The cylinder can provide uniform and stable power output, and can achieve reciprocating motion, thereby improving the overall stability of the equipment. The forward and backward movement of the piston rod of the second cylinder can rotate the pressure block hinged on the piston rod, so that the workpiece can rotate to achieve automatic face changing.

[0063] Of course, according to actual conditions, in some other embodiments, the fourth driving mechanism 620 can be replaced by a servo motor, which is arranged on the lifting platform 640 and is connected to the pressing block 630 through gears, so that the servo motor can drive the pressing block 630 to rotate and realize the rotation of the workpiece.

[0064] The following describes in detail the workflow of the automatic cutting device according to this embodiment. It is worth noting that the following description is only an exemplary description and is not a specific limitation of the invention.

[0065] First, the control unit 200 is used to control the movable frame 500 to rise until the support seat 560 is higher than the top of the two saw blades 410, so that the movable frame 500 is in the initial state, which is convenient for the staff to safely disassemble and assemble the workpiece. The staff clamps the protrusions 633 on both sides of the runner of the workpiece between the two side grooves 632 of the two pressure strips 631. The positioning mechanism 700 is controlled to move forward to support the runner of the workpiece and push the workpiece so that the workpiece is aligned with the groove 562 of the support block 561. Then, the control unit 200 is used to control the clamping mechanism 600 to move downward so that the groove 562 of the support block 561 is engaged and pressed with the lower runner of the workpiece. After the workpiece is pressed, the first driving mechanism 800 drives the rotating shaft 820 to rotate, thereby driving the saw blade unit 400 to rotate. When the saw blade unit 400 reaches a certain speed, the movable frame 500 drives the workpiece to move downward so that the two sides of the workpiece are close to the two saw blades 410 for cutting. When the workpiece needs to be cut on multiple sides, the movable frame 500 can be raised until the top of the support seat 560 is higher than the saw blade unit 400 after the saw blade 410 completes one cut, and then the control unit 200 controls the second cylinder 621 to push the pressing block 630 to rotate, so that the workpiece rotates 90 degrees, and then the movable frame 500 is lowered to continue cutting the workpiece. After the cutting is completed, the movable frame 500 is reset to the initial state, and the staff disassembles the workpiece to start the next round of cutting cycle.

[0066] According to the automatic cutting equipment of the second embodiment of the present invention, by such an arrangement, at least the following effects can be achieved: the first driving mechanism 800 drives the two saw blades 410 of the two saw blade units 400 to rotate to cut the workpiece and the second driving mechanism 830 drives the workpiece on the movable frame to approach the two saw blades 410, while the fourth driving mechanism 620 drives the pressing block 630 to rotate to realize the automatic face changing function of the workpiece, so that the workpiece can automatically complete the separation of the four-side casting body and the runner during the casting cutting process, thereby improving the efficiency of workpiece cutting.

[0067] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
