Description

Technical Field

[0001] The invention belongs to the technical field of metal casting cutting, and in particular relates to an automatic cutting device for cutting metal castings. Background Art

[0002] Metal castings are made by melting metal into a liquid that meets certain requirements and pouring it into a mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained.

[0003] Most metal castings cast by investment casting are cast in batches by means of a tree assembly method to form multiple identical metal castings, and then the final metal castings are separated from the pouring system by cutting.

[0016] 2. The symmetrical cutting disc of the present invention is suspended above the metal casting through symmetrical bending upright plates. When the symmetrical bending upright plates are close to each other, the first locating pin and the second locating pin will connect the symmetrical bending upright plates to form a whole, so that the two cutting discs close to each other can slide synchronously, and the pouring channels on both sides of the pouring system can be synchronously cut and separated; and when the piston rod of the symmetrical push cylinder contracts, the symmetrical bending upright plates will slide away from each other, and the first locating pin and the second locating pin will slide out of the corresponding through holes respectively, so that the symmetrical cutting discs can independently cut and remove the cap waste remaining on the end face of the metal casting, thereby preventing the phenomenon that there is too much cap waste remaining on the end face of a certain metal casting and it cannot be quickly removed.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Specifically, the present invention sets a casting clamping mechanism 2 on both side walls of the receiving bin 11, and the tree-shaped metal castings to be cut are clamped and fixed to the upper bin opening of the receiving bin 11 by the casting clamping mechanism 2, and the sliding support mechanism 3 can drive the cutting conversion mechanism 4 to slide above the clamped and fixed metal castings, and then drive the cutting disc 41 to descend through the sliding support mechanism 3, so that it first contacts the pouring channel between the metal casting and the pouring system, and then the symmetrical high-speed rotation and continuous sliding of the cutting disc 41 will quickly cut and separate the multiple metal castings from the pouring system, and the pouring system after cutting It will directly fall into the material receiving bin 11, at which time the multiple metal castings after cutting and separation will continue to be clamped and fixed by the casting clamping mechanism 2, and then the symmetrical cutting discs 41 will move away from each other, so that the cutting disc 41 slides close to the end face of the clamped metal casting, so that the rotating cutting disc 41 continues to accurately and quickly cut off the cap waste remaining on the end face of the metal casting, preventing the waste remaining on the metal casting from not being completely cut and affecting its normal use, and then the casting clamping mechanism 2 disengages from clamping and fixing the cut and cleaned metal casting, and the processing personnel remove the cut and separated metal casting from the cutting table 1 for storage.

[0030] In this embodiment, the casting clamping mechanism 2 includes a fixed block 21, an arc-shaped support block 22, an arc-shaped slider 23, a T-block 24, a connecting strip 25, a threaded rod 26, an adjusting nut 27 and a support block 28. At least three positioning grooves 12 are horizontally opened on the front and rear side groove walls of the receiving bin 11, and a fixed block 21 is installed below the notch of the positioning groove 12. The upper surface of the fixed block 21 is formed with an arc-shaped support block 22 with an opening facing upward, and the arc-shaped opening of the arc-shaped support block 22 is flush with the notch of the positioning groove 12. The upper end surface of the arc-shaped support block 22 is slidably fitted with an arc-shaped slider 23, and the arc-shaped opening of the arc-shaped slider 23 faces downward and matches the arc-shaped opening of the arc-shaped support block 22 to form a positioning card. Ring, the upper surfaces of the two ends of the arc-shaped opening of the arc-shaped support block 22 are formed with T-shaped blocks 24 along the width direction thereof, the lower surfaces of the two ends of the arc-shaped sliding block 23 with the opening facing downward are penetrated with T-shaped sliding grooves 231, and the T-shaped sliding grooves 231 are slidably sleeved on the T-shaped blocks 24, the top ends of at least three arc-shaped sliding blocks 23 are connected to each other through a connecting strip 25, and at least two threaded rods 26 are rotatably installed on the outer end surface of the connecting strip 25, at least two support blocks 28 are symmetrically fixed on the front and rear sides of the cutting table 1, and the inner side surface of each support block 28 is fixed with an adjusting nut 27, and the outer end of each threaded rod 26 is threaded through the adjusting nut 27 and penetrates the outer side surface of the supporting block 28;

[0031] Specifically, when the metal castings of the tree group to be cut are hoisted to the upper warehouse opening of the material receiving bin 11, the multiple columnar metal castings will fall into the multiple positioning grooves 12 accordingly, and the bosses of the metal castings will extend into the material receiving bin 11, and the upper arc-shaped mouth of the arc-shaped support block 22 will be supported between the extended metal castings and the bosses, so that the metal castings are limited in the axial direction, and then the threaded rod 26 threadedly connected by the adjusting nut 27 on the support block 28 is twisted to push the multiple arc-shaped sliders 23 with the openings facing downward to slide on the columnar metal castings through the connecting strips 25, and the arc-shaped sliders 23 will slide and fit onto the arc-shaped support block 22, and at this time the T-shaped slide groove 231 will be slidably sleeved on the T-shaped block 24, so that the arc-shaped support block 22 and the arc-shaped slider 23 are connected to each other to form a positioning clamp, so as to realize multiple The metal casting is clamped and fixed in the vertical direction to prevent the cutting disc 41 from continuously rotating and sliding to cut the channel between the metal casting and the pouring system, and the thrust and pressure of the cutting disc 41 cause the metal casting to fall out of the positioning groove 12, thereby affecting the rapid cutting and separation effect between the metal casting and the pouring system; and when the metal casting is completely cut and removed, the threaded rod 26 is reversely twisted to drive the multiple arc-shaped sliders 23 to slide and disengage from the multiple arc-shaped support blocks 22 through the connecting strip 25, and the multiple arc-shaped sliders 23 slide to the outside of the positioning groove 12, and the sliding support mechanism 3 drives the cutting conversion mechanism 4 to disengage from the top of the cut metal casting, thereby facilitating the rapid disengagement and clamping of the cut metal casting, and quickly taking it out of the positioning groove 12 for storage.

[0032] In this embodiment, the sliding support mechanism 3 includes a crossbeam frame 31, a sliding support block 32, a lifting cylinder 33, a lifting block 34 and a push cylinder 35. The two crossbeam frames 31 are symmetrically fixed on the front and rear side walls of the cutting table 1, and a transmission screw is rotatably installed in each crossbeam frame 31. A sliding support block 32 is slidably arranged in the crossbeam frame 31, and the sliding support block 32 is connected to the transmission screw through a screw nut. The upper surface of the sliding support block 32 is vertically fixed with a lifting cylinder 33, and the top surface of the piston rod of the lifting cylinder 33 is fixed with a lifting block 34. The side of the lifting block 34 is horizontally fixed with a push cylinder 35, and the end surface of the piston rod of the push cylinder 35 is connected with the cutting conversion mechanism 4.

[0033] Specifically, the drive screw is driven to rotate by the servo motor fixed at the end of the beam frame 31, so that it drives the sliding support block 32 to drive the lifting cylinder 33 to slide along the length direction of the beam frame 31, and the lifting block 34 will drive the horizontally fixed push cylinder 35 to slide above the metal casting to be cut, thereby facilitating the driving of the cutting conversion mechanism 4 to slide along the length direction of the pouring system, and quickly cutting and separating the symmetrical and multiple pouring channels. The piston rod of the lifting cylinder 33 extends or retracts to drive the symmetrical cutting discs 41 to move up and down above the clamped metal casting, and the piston rod of the push cylinder 35 extends or retracts to drive the symmetrical cutting discs 41 to move closer or farther away from each other, so that the pouring system and the metal casting can be cut and separated first, and then the cap mouth waste remaining on the end face of the metal casting can be cut and removed.

[0034] In this embodiment, the cutting conversion mechanism 4 also includes a bending vertical plate 42, a pulley assembly 43, a transmission shaft 44, a positioning sleeve 45 and a locking nut 46. The outer side surface of the upper vertical plate 421 of the bending vertical plate 42 is connected to the piston rod end surface of the push cylinder 35, and the outer side surface of the lower vertical plate 422 of the bending vertical plate 42 is installed with a pulley assembly 43, and the pulley assembly 43 is connected to the transmission shaft 44. The transmission shaft 44 is rotatably connected to the lower vertical plate 422 of the bending vertical plate 42 through a bearing, and the transmission shaft 44 passes through the inner side surface of the lower vertical plate 422 and is installed with a cutting disc 41. The cutting disc 41 and the inner side surface of the lower vertical plate 422 are directly installed with a positioning sleeve 45, and the positioning sleeve 45 is sleeved on the transmission shaft 44. The outer side surface of the cutting disc 41 contacts with the locking nut 46 through a washer, and the locking nut 46 is threadedly connected to the threaded rod 26 formed at the end of the transmission shaft 44.

[0035] Specifically, when it is necessary to separate the pouring system and the clamped metal casting first, the symmetrical transmission screw will first drive the symmetrical cutting disc 41 to slide to the end of the pouring system, and then the piston rod of the symmetrical lifting cylinder 33 will contract, so that it drives the bottom end of the symmetrical cutting disc 41 to drop below the pouring channel, and then the servo motor connected to the pulley assembly 43 is controlled to work, so that it drives the cutting disc 41 to rotate rapidly through the pulley assembly 43 and the transmission shaft 44, and the rotation of the transmission screw will drive the symmetrical and rapidly rotating cutting disc 41 to slide continuously to cut multiple pouring channels, so that the metal casting and the pouring system can be quickly separated, and the cut waste will fall into the receiving bin 11, and when it is necessary to cut off the cap waste remaining on the end face of the cut metal casting, the piston rod of the push cylinder 35 is controlled to contract, so that the symmetrical bending vertical plates 42 slide away from each other, which will drive the symmetrical cutting discs 41 to move away from each other. The lower plate 422 of the bending vertical plate 42 will not interfere with the cutting disc 41 when the cutting disc 41 is lowered to fit the end face of the metal casting to cut the cap waste. The lower plate 422 of the bending vertical plate 42 will not interfere with the cutting disc 41, so that the symmetrical cutting discs 41 can be close to each other to cut and separate the metal casting and the pouring system first, and then move away from each other to cut and clean the cap waste at the end face of the metal casting, so that the processing personnel do not need to manually cut and grind the cap waste separately. The positioning sleeve 45 is sleeved on the transmission shaft 44, so that it can limit the cutting disc 41 sleeved on the transmission shaft 44 to prevent the rapidly rotating cutting disc 41 from hitting the lower plate 422 of the bending vertical plate 42. The removal of the locking nut 46 facilitates the removal and replacement of the damaged cutting disc 41.

[0036] In this embodiment, the cutting conversion mechanism 4 further includes a first positioning pin 47 and a first positioning pin 48, wherein the first positioning pin 47 is symmetrically fixed to the front side of the upper vertical plate 421 on the rear side, and the first positioning pin 47 is symmetrically slid through the through hole 423 provided through the upper vertical plate 421 on the front side, and the first positioning pin 48 is symmetrically fixed to the rear side of the upper vertical plate 421 on the front side, and the pneumatically symmetrical first positioning pin 48 also slides through the through hole 423 provided through the upper vertical plate 421 on the rear side, and the first positioning pin 48 is symmetrically located inside the first positioning pin 47;

[0037] Specifically, when the symmetrically bent upright plates 42 approach each other, so that the symmetrical cutting discs 41 approach each other to cut and separate the metal casting and the pouring system, the first positioning pin 48 on the front upper vertical plate 421 will slide and insert into the through hole 423 opened on the rear upper vertical plate 421, and the first positioning pin 47 will slide and insert into the through hole 423 opened on the front upper vertical plate 421 synchronously, and then when the symmetrical cutting discs 41 approach each other, the symmetrically bent upright plates 42 will be connected to each other to form a whole, so that the metal casting and the pouring system are cut and separated. The two cutting discs 41 close to each other can slide synchronously to achieve synchronous cutting and separation of the pouring channels on both sides of the pouring system; and when the piston rod of the symmetrical push cylinder 35 contracts, the symmetrical bending vertical plates 42 will slide away from each other, and then the first locating pin 47 and the first locating pin 48 will slide out from the corresponding through holes 423 respectively, so that the symmetrical cutting discs 41 can independently cut and remove the cap mouth waste remaining on the end face of the metal casting, thereby preventing the phenomenon that too much cap mouth waste remains on the end face of a metal casting and cannot be quickly removed.

[0038] In this embodiment, the sliding support mechanism 3 further includes a suspension plate 36 and a T-shaped strip 37. The upper surfaces of the symmetrical lifting blocks 34 are horizontally fixed with suspension plates 36, and the symmetrical suspension plates 36 are located above the push cylinder 35. The lower surface of the suspension plate 36 is connected to the cylinder body of the push cylinder 35, and the lower surface of the suspension plate 36 is fixed with a T-shaped strip 37 along its length direction. The length of the T-shaped strip 37 is less than the length of the piston rod of the push cylinder 35. The upper vertical plate 421 of the bending vertical plate 42 is provided with a T-shaped guide groove 424, and the T-shaped guide groove 424 is slidably sleeved on the T-shaped strip 37. The symmetrical suspension plates 36 and T-shaped strips 37 are designed separately from each other.

[0039] Specifically, when the piston rod of the push cylinder 35 contracts or extends, the bending vertical plate 42 will cooperate with the T-shaped guide groove 424, the T-shaped strip 37 and the suspension plate 36 provided on the top, so as to guide, position and suspend the sliding bending vertical plate 42, thereby preventing the bending vertical plate 42, the pulley assembly 43 and the cutting disc 41 from being only connected to the piston rod of the push cylinder 35, and the cutting disc 41 from shaking or tilting during the cutting operation.

[0040] In this embodiment, the outer end of the threaded rod 26 located at the support block 28 is designed as a hexagon socket screw; specifically, the design of the hexagon socket screw not only facilitates the twisting of the threaded rod 26, but also does not interfere with the normal horizontal sliding of the lifting cylinder 33.

[0041] In this embodiment, a conveyor belt 5 is provided at the bottom of the receiving bin 11 through a rotating roller; specifically, when it is necessary to take out and collect the casting system waste collected at the bottom of the receiving bin 11, the conveyor belt 5 is controlled by a control switch, so that the casting system dropped from the conveyor belt 5 will be transported to the bin mouth of the receiving bin 11 for removal, thereby facilitating the rapid removal of the waste accumulated at the bottom of the receiving bin 11.
