Description

Technical Field

[0002] In the steel profile processing industry, steel profiles, as an important engineering material, are widely used in many fields such as construction, machinery, and transportation. The cutting of steel profiles is a key step in the processing process, and usually requires precise cutting technology to ensure that the size and surface quality of the profile meet the requirements. Most existing steel profile cutting devices use manual or mechanized loading methods. However, manual loading is not only inefficient, but also limited by the skills and physical strength of the operator, which can easily lead to unnecessary errors in the production process. In addition, many existing cutting devices still rely on manual or relatively simple mechanical feeding systems during the feeding process of the profile, and cannot guarantee the precise transmission of the profile. This not only increases labor intensity, but may also cause cutting errors, thereby affecting cutting accuracy and processing quality. On the other hand, traditional cooling systems usually rely on external equipment to spray coolant.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Please see the attached Figure 1 - Attachment Figure 7 The embodiment of the present invention provides an automatic cutting device suitable for steel profile processing, comprising a mounting base 1, a supporting frame 2 is mounted on the top of the mounting base 1, a threaded rod is rotatably mounted on the inner side of the supporting frame 2, a motor for rotating with the threaded rod is mounted on the outer side of the supporting frame 2, the external thread of the threaded rod is connected to a threaded sleeve, two connecting plates 401 are mounted on the top of the threaded sleeve through an electric rotating shaft, a mounting cylinder 402 is mounted on one end of the connecting plate 401, a cylinder 403 is mounted on the outer side of the mounting cylinder 402, the telescopic end of the cylinder 403 passes through one end of the mounting cylinder 402 and is fixedly connected to a double-sided rack 408, the inner side of the mounting cylinder 402 is movably connected to two driving gears 404 through a bearing, the outer side of the driving gear 404 is movably connected to a first connecting rod 405, a second connecting rod 406 is hinged to one side of the mounting cylinder 402, and a splint 407 is hinged to one end of the second connecting rod 406, and a cutting assembly is mounted on the inner side of the support frame 2, which is used to cut the steel profile.

[0027] Specifically, the mounting base 1 serves as the basic component of the entire cutting device, providing a stable support and fixing foundation for other components. The support frame 2 is installed on the top of the mounting base 1, carrying the various components of the entire cutting device, and realizing the movement adjustment of the device through the rotating threaded rod inside it. The design of the support frame 2 ensures the coordination and stability of the various components during operation. A threaded rod is rotatably installed on the inner side of the support frame 2, and the threaded rod is able to rotate precisely by cooperating with the outer motor. The threaded sleeve on the outside of the threaded rod matches its thread, and the rotation of the threaded rod is driven by the motor, thereby driving the threaded sleeve to move along its axial direction.

[0028] The function of the adapter plate 401 is to adjust its angle via a motorized shaft to accommodate the steel profile being unloaded from the conveyor belt 303. The cylinder 403, through its telescopic motion, drives the movement of the double-sided rack 408, which in turn rotates the drive gear 404 within the mounting cylinder 402. The drive gear 404, in conjunction with the first connecting rod 405, drives the closing movement of the clamping plate 407. The clamping plate 407 clamps and secures the steel profile to be cut, ensuring its stability during the cutting process.

[0029] The cutting assembly includes a drive shaft 501 rotatably mounted on one side of the interior of the support frame 2. A drive motor for rotating the drive shaft 501 is mounted on the exterior of the support frame 2. Two saw discs 502 are fixedly connected to the exterior of the drive shaft 501. A support rod 504 is fixedly connected to the top side of the mounting base 1. A grinding disc 503 is mounted on the exterior of the support rod 504. The grinding disc 503 and the saw disc 502 are connected via a transmission assembly. The transmission assembly includes two sets of synchronous wheels, one set of which is fixedly connected to the front and rear sides of the drive shaft 501, and the other set of synchronous wheels is fixedly connected to the exterior of the grinding disc 503. Both sets of synchronous wheels are connected by a belt.

[0030] Specifically, the cutting assembly is one of the core parts of the mechanical device and is responsible for the cutting operation.

[0031] The drive motor is installed on the outside of the support frame 2 and drives the transmission shaft 501 to rotate through its output shaft. The drive motor provides power so that the entire cutting system can be operated. Two saw discs 502 are fixedly connected to both sides of the transmission shaft 501. The two saw discs 502 rotate through the rotation of the transmission shaft 501, thereby realizing the cutting function. The support rod 504 plays a supporting role, fixes the grinding disc 503, and ensures the relative position and stability of the grinding disc 503 and the saw disc 502. The rotation of the grinding disc 503 helps to smooth the surface of the cut object, ensuring that the surface after cutting is smooth and burr-free.

[0032] The transmission assembly connects and coordinates the work between the saw disc 502 and the grinding disc 503. The two sets of synchronous wheels are connected by a belt. The belt transmits power and ensures precise synchronization between the two sets of synchronous wheels, thereby enabling the grinding disc 503 to operate synchronously with the saw disc 502. This design ensures the coordination and efficiency of the cutting and grinding processes.

[0033] It has the following effects:

[0034] The structure is compact, and the cutting and grinding functions are integrated into the same system. The ingenious design of the transmission components enables the two to work synchronously.

[0035] The efficient synchronous transmission, connected by a synchronous wheel and a belt, ensures efficient and precise coordination between the grinding disc 503 and the saw disc 502, thus avoiding power transmission errors.

[0036] Versatility: the device can not only cut, but also perform surface grinding after cutting, reducing the need for subsequent processing and improving production efficiency.

[0037] A liquid storage tank 6 is installed in the middle of the top of the installation base plate 1. A filter screen 7 is detachably connected to the inner side of the liquid storage tank 6. An electric telescopic rod is installed on the outer side of the liquid storage tank 6. The output end of the electric telescopic rod passes through the outer side of the liquid storage tank 6 and is fixedly connected to a scraper. A discharge trough is opened on the outer side of the liquid storage tank 6.

[0038] Specifically, the scraper is driven to move by starting the electric telescopic rod, and the scraper moves along the outer surface of the filter screen 7, so that the debris on the outer surface of the filter screen 7 can be discharged through the discharge chute to prevent the filter screen 7 from being blocked.

[0039] The front and rear ends of the transmission shaft 501 are fixedly connected to sector gears 803. Two movable plates 801 are slidably mounted on the outside of the support frame 2. Drive racks 802 are fixedly mounted on the upper and lower sides of the movable plates 801. A fixed cylinder 804 is fixedly connected to the bottom of the support frame 2. A connector 807 is slidably mounted inside the fixed cylinder 804. The outer surface of the fixed cylinder 804 is connected to a first connecting pipe 805 and a second connecting pipe 806. Both the first and second connecting pipes 805 and 806 are equipped with one-way valves, each with opposite conduction directions. The outer sides of the sector gears 803 mesh with the outer sides of the two drive racks 802, respectively. The end of the connector 807, facing away from the fixed cylinder 804, is fixedly connected to the outer side of the movable plate 801. The end of the second connecting pipe 806 is located near the outside of the saw disc 502. One end of the first connecting pipe 805 is connected to the interior of the liquid reservoir 6. The outer side of the driving gear 404 is meshed with the outer side of the double-sided rack 408 , and one end of the first connecting rod 405 away from the driving gear 404 is fixedly connected to one side of the clamping plate 407 .

[0040] Specifically, the driving rack 802 is connected to the movable plate 801, so that the movable plate 801 is driven by the rack to perform a reciprocating motion. This motion is intermittent, mainly due to the meshing mode of the sector gear 803 and the driving rack 802.

[0041] The fixed cylinder 804 is structurally connected to the movable plate 801, and its interior can generate negative or positive pressure when driven by the movable plate 801. The fixed cylinder 804 is connected to the liquid reservoir 6. Under negative pressure, coolant is drawn from the liquid reservoir 6 into the fixed cylinder 804. When the movable plate 801 moves in the opposite direction, the coolant in the fixed cylinder 804 is ejected through the second connecting pipe 806 to cool the saw disc 502.

[0042] The system is connected to the liquid storage tank 6 via a first connecting pipe 805. Coolant is drawn from the liquid storage tank 6 into the fixed cylinder 804. When the coolant in the fixed cylinder 804 is forced out, it flows through the second connecting pipe 806 to the saw disc 502, cooling it. After being filtered by the filter screen 7, the coolant flows back to the liquid storage tank 6, forming a closed cooling cycle.

[0043] The function of the one-way valve in the first connecting pipe 805 is to allow coolant to flow from the liquid reservoir 6 into the fixed cylinder 804 through the first connecting pipe 805 when negative pressure is generated in the fixed cylinder 804. At this time, the one-way valve in the first connecting pipe 805 allows coolant to flow from the liquid reservoir 6 into the fixed cylinder 804, but prevents reverse flow, ensuring that coolant does not return from the fixed cylinder 804 to the liquid reservoir 6.

[0044] The function of the one-way valve in the second connecting pipe 806 is that when the movable plate 801 moves in the reverse direction, the coolant in the fixed cylinder 804 is pushed to the saw disc 502 in the working state through the second connecting pipe 806. At this time, the one-way valve in the second connecting pipe 806 allows the coolant to flow outward and into the saw disc 502, while preventing the coolant from flowing back from the saw disc 502 into the fixed cylinder 804.

[0045] Its operating principle is based on the process of combining mechanical movement with liquid flow:

[0046] The transmission shaft 501 rotates, driving the sector gear 803 to rotate. The meshing action of the sector gear 803 and the drive rack 802 causes the movable plate 801 to perform linear reciprocating motion. The movement of the movable plate 801 drives the fixed cylinder 804 to operate through the connector 807, so that a negative pressure is formed in the fixed cylinder 804. Since the fixed cylinder 804 is connected to the liquid storage tank 6, when a negative pressure is formed, the coolant in the liquid storage tank 6 is sucked into the fixed cylinder 804. When the movable plate 801 moves in the opposite direction, the coolant in the fixed cylinder 804 is ejected through the second connecting pipe 806 to cool the working saw disc 502. The saw disc 502 is cooled down by the action of the coolant, and the coolant is filtered through the filter screen 7 and then flows back to the liquid storage tank 6 to maintain the cooling efficiency of the system.

[0047] The innovation of this structure lies in its automatic coolant circulation system. By mechanically controlling the intake and ejection of coolant, the saw disc 502 is kept at a consistently low temperature during operation, effectively preventing overheating and improving the efficiency and lifespan of the equipment. The entire coolant circulation process is automated, requiring no external manual intervention.

[0048] A support frame 302 is fixedly connected to one side of the top of the support frame 2, a conveyor belt 303 is installed on the inner side of the support frame 302, and partition plates 304 are fixedly connected to the outer surface of the conveyor belt 303 at equal intervals. A placement box 301 is fixedly connected to the top of the support frame 302.

[0049] Specifically, the steel profiles inside the placement box 301 are placed on the outer surface of the conveyor belt 303. At this time, the conveyor belt 303 is driven to move the partition plate 304 on its outer surface, thereby moving multiple steels to be cut, realizing the automatic loading function, greatly reducing the need for manual operation, improving production efficiency, and reducing labor intensity.

[0050] Working principle: The specific use of this device includes the following steps:

[0051] Step 1: Place the steel profiles in the placement box 301 on the outer surface of the conveyor belt 303. At this time, the conveyor belt 303 is driven to move the partition plate 304 on its outer surface, thereby moving multiple steels to be cut. At this time, the connecting plate 401 is driven by the electric shaft to deflect at an angle. At this time, the cylinder 403 is started to drive the double-sided rack 408 to move, thereby driving the two driving gears 404 to rotate. At this time, the first connecting rod 405 on the outer side of the driving gear 404 swings, and the clamping plates 407 are pulled closer to each other by the traction force of the second connecting rod 406 until the steel to be cut is clamped and fixed;

[0052] Step 2. After clamping the steel, start the two motors on the outside of the mounting support frame 2 in sequence. The drive of the two motors drives the threaded rod and the transmission shaft 501 to rotate in sequence. The rotation of the transmission shaft 501 drives the two saw discs 502 to rotate coaxially. The saw disc 502 drives the grinding disc 503 to rotate through the transmission assembly. The threaded sleeve is moved by the rotation of the threaded rod. During the movement of the threaded sleeve, the mounting cylinder 402 is driven to move synchronously. In this way, the clamped steel profile is moved, and the saw disc 502 in the working state is used to cut the two ends of the steel profile. After the cutting is completed, the mounting cylinder 402 continues to move forward, and the two ends of the cut steel profile are deburred by the grinding disc 503.

[0053] Step three, during the rotation of the transmission shaft 501, the sector gear 803 will also be driven to rotate. At this time, the sector gear 803 will intermittently mesh with the two driving racks 802, thereby driving the movable plate 801 to move back and forth. When the movable plate 801 moves, it drives the connector 807 to move synchronously. When the connector 807 moves in the direction away from the fixed cylinder 804, the interior of the fixed cylinder 804 is in a negative pressure state. Since the fixed cylinder 804 is connected to the liquid storage tank 6 through the first connecting pipe 805, the coolant inside the liquid storage tank 6 can be sucked into the interior of the fixed cylinder 804. When the connector 807 moves in the opposite direction, the coolant inside the fixed cylinder 804 is sprayed into the saw disk 502 in the working state through the second connecting pipe 806 to cool the saw disk 502. At this time, the coolant is filtered through the filter 7 and flows back to the interior of the liquid storage tank 6 again.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
