Description

Technical Field

[0001] This invention relates to the field of hardware processing technology, and in particular to an integrated device for cutting and grinding hardware parts. Background Technology

[0002] Hardware processing refers to the process of cutting, plastically deforming, and surface treating metal materials (such as steel, copper, aluminum, zinc alloys, stainless steel, etc.) to manufacture parts with specific shapes, sizes, precision, and functions.

[0003] An existing patent (publication number: CN119772606B) discloses an integrated machine for cutting and grinding hardware parts. Its technical solution includes: a base frame; a cutting component is fixedly installed on one side of the top of the base frame; a processing table is fixedly installed on one side of the front end of the base frame; a discharge chute is fixedly installed on the other side of the front end of the base frame via a first support frame; a grinding component is movably installed below the discharge chute; the grinding component includes a first grinding chamber and a second grinding chamber, the first and second grinding chambers being of matched dimensions, and the opposite sides of the first and second grinding chambers being connected via a flap valve; the rotating component includes a stepper motor installed on the back of the base frame, a drive shaft being driven by a coupling on the stepper motor, and a connecting frame welded to the front end of the drive shaft. This invention effectively solves the problem of hardware parts needing to be individually clamped and ground after cutting, and the problem of limited overall work efficiency due to the ability to process only a single hardware part at a time. The aforementioned integrated cutting and grinding device addresses the problem of individual clamping and grinding of cut metal parts, but it can only process a single metal part at a time, limiting overall work efficiency. However, the device's instruction manual states, "After cutting, turn off the drive motor 241, and reset the Y-axis cylinder 21 and Z-axis cylinder 22. At this time, the cut metal part will automatically fall into the collection device below through the discharge chute 12. The collection device can be placed directly on the sliding cover 313 of the first grinding chamber 31 or the second grinding chamber 33 below the discharge chute 12. If multiple metal parts need to be cut continuously, the above steps can be repeated." In other words, the cut metal part falls into the grinding mechanism for grinding. Therefore, when cutting and grinding longer metal parts, such as angle steel, the angle steel trapped inside the device cannot be ground, making it inconvenient to grind both ends of the cut angle steel simultaneously, thus limiting its application scenarios.

[0004] Therefore, it is necessary to solve the above problems by using an integrated device for cutting and grinding hardware parts. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device for cutting and grinding hardware parts to solve the problems mentioned in the background art.

[0006] The objective of this invention is achieved through the following technical solution: A hardware cutting and grinding integrated device includes a frame, a drive mechanism for driving the cutting component to rotate is installed on the side of the frame, a support platform is fixedly installed inside the frame, the central area of ​​the support platform has a multi-hollow structure, a moving mechanism is fixedly installed on the upper surface of the support platform, and an adaptation mechanism is fixedly installed on the upper surface of the moving mechanism. The adaptation mechanism is used to drive the hardware to rotate in coordination with the cutting component to cut the hardware, and the moving mechanism is used to drive the adaptation mechanism to make linear motion. A return grinding component is also provided below the moving mechanism for sandblasting and grinding the cut hardware.

[0007] Preferably, the adapting mechanism includes a cutting table with a U-shaped structure. Alloy sleeves are rotatably connected to the inner walls of the cutting table on both sides. The inner wall of one alloy sleeve has an L-shaped structure, and an L-shaped abutment is provided corresponding to the L-shaped structure for clamping the angle steel. A screw is rotatably connected to the upper surface of the abutment, and the screw is threadedly connected to the alloy sleeve. An L-shaped electromagnet is fixedly installed on the inner wall of the other alloy sleeve for adsorbing the other end of the angle steel. A gear is fixedly mounted on the circumference of an alloy sleeve equipped with an electromagnet, and a rack is fixedly mounted on the inner wall of the frame. The gear and rack mesh together, and a reliable composite clamping force is formed by the mechanical clamping of an adjustable screw at one end and the attraction and fixation of the electromagnet at the other end. This ensures that the workpiece does not shift during cutting and grinding. At the same time, the meshing design of the gear and rack allows the workpiece clamping mechanism to automatically rotate under drive, so that cutting and grinding can be carried out simultaneously, improving the efficiency of angle steel cutting and grinding.

[0008] Preferably, the central area of ​​the upper surface of the cutting table has a sloping structure to assist the return of gravel. It can effectively guide and collect debris, abrasive and other impurities generated during processing. The sloping structure uses gravity to achieve automatic sliding and collection of waste materials, preventing them from accumulating on the worktable and thus ensuring the cleanliness of the processing area.

[0009] Preferably, an arc-shaped rebound net is fixedly installed on one side of the upper surface of the cutting table to rebound the grit during the grinding process. The arc-shaped rebound net can rebound some of the high-speed sprayed grit back to the workpiece surface or working area, increasing the effective impact number of the grit and improving the grinding efficiency and media utilization.

[0010] Preferably, the moving mechanism includes a rodless cylinder fixed along the width direction of the support platform and two guide rods. The rodless cylinder is located between the two guide rods and a moving base is slidably sleeved along the two guide rods. The moving base is fixedly connected to the sliding block of the rodless cylinder. The bottom surface of the cutting table is slidably connected to the upper surface of the moving base through a self-locking slide rail. The cutting table slides along the length direction of the moving base. Through the cooperation of the rodless cylinder and the guide rods, the smooth linear movement of the moving base is realized, ensuring precise control of the workpiece position during cutting and grinding. The cutting table can slide along the moving base and be pulled out by a pull rod, which facilitates the safe and convenient handling of angle steel by the operator, improving the convenience and safety of operation.

[0011] Preferably, the recirculation grinding assembly includes a recirculation hopper fixedly installed on the inner wall of the frame, the inner bottom wall of the recirculation hopper having a sloping structure for guiding the gravel, a storage box fixedly installed on the inner bottom wall of the frame, and the bottom of the recirculation hopper being connected to the storage box via a pipe. An air compressor connector is fixedly installed on the inner top wall of the frame. The input end of the air compressor connector is connected to the storage tank through pipe two, and the output end of the air compressor connector is fixedly connected to a three-way pipe. The two output ends of the three-way pipe are respectively fixedly connected to sandblasting nozzles for blasting gravel to grind angle steel. The inclined inner bottom wall of the return hopper can automatically guide the used gravel to the storage tank, realizing the recycling and reuse of gravel. The air compressor connector sucks in the gravel from the storage tank and sends it to the sandblasting nozzles through the three-way pipe for circulating spraying, forming a closed-loop sandblasting and grinding system, which effectively reduces gravel consumption, improves resource utilization, and ensures the continuity and stability of the grinding process.

[0012] Preferably, the cutting assembly includes a cutting spindle rotatably connected to the inner wall of the frame, one end of the cutting spindle passing through the frame, and a cutting blade fixedly mounted on the circumferential surface of the cutting spindle, the position of which corresponds to the central area of ​​the two alloy sleeves.

[0013] Preferably, the drive mechanism includes a servo motor fixedly mounted on the upper surface of the frame. The output end of the servo motor is connected to the synchronous belt drive via a synchronous pulley at one end corresponding to the cutting spindle. An adjusting pulley for adjusting the tension of the synchronous belt is also installed on one side of the frame. The adjusting pulley can be adjusted in position. The servo motor, in conjunction with the synchronous belt drive, can achieve smooth cutting spindle operation and speed control. The adjustable tension pulley design allows the synchronous belt to be re-tensioned when it becomes loose due to stretching after long-term use, thereby maintaining high transmission efficiency and avoiding slippage.

[0014] The beneficial effects of this invention are: This invention discloses an integrated cutting and grinding device for hardware parts. When an angle steel is transported to the cutting mechanism via a moving mechanism, the angle steel rotates to assist in cutting. Simultaneously, a return grinding mechanism sandblasts and grinds the cut surface of the angle steel, achieving integrated cutting and grinding operations. This eliminates the need for inter-process transfer and secondary clamping time, improving processing efficiency. Crucially, two sandblasting nozzles simultaneously spray gravel onto the two cut surfaces formed after the angle steel is cut, ensuring that both cut surfaces of the separated angle steel achieve the same degree of smoothness, guaranteeing consistent cross-sectional quality, and avoiding asymmetry where one end is sufficiently ground while the other is not. During this process, the ramp and return hopper automatically recycle the gravel, supporting continuous grinding operations. All mechanisms work in tandem, simultaneously completing cutting and double-end grinding within the integrated workstation, achieving highly efficient continuous processing.

[0017] To make the technical problems solved by the invention, the technical solutions and the beneficial effects clearer, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] Embodiments provided by the present invention: The present invention provides, as follows Figures 1 to 8 As shown, a hardware cutting and grinding integrated device includes a frame 1. During use, multiple sides of the frame 1 are enclosed by sheet metal, with one side reserved for installing a door panel. This allows for the removal of angle steel when the door panel is opened, preventing sand and gravel from leaking out. A drive mechanism 3 for driving the cutting assembly 2 to rotate is installed on the side of the frame 1. A bearing platform 4 is fixedly installed inside the frame 1. The central area of ​​the bearing platform 4 has a multi-hollow structure. A moving mechanism 5 is fixedly installed on the upper surface of the bearing platform 4. An adaptation mechanism 6 is fixedly installed on the upper surface of the moving mechanism 5. The adaptation structure is used to drive the hardware to rotate in coordination with the cutting assembly 2 to cut the hardware. The moving mechanism 5 is used to drive the adaptation structure to make linear motion. A return grinding assembly 7 is also provided below the moving mechanism 5 for sandblasting and grinding the cut hardware.

[0019] The adapting mechanism 6 includes a cutting table 601, which has a U-shaped structure. Alloy sleeves 602 are rotatably connected to the inner walls of both sides of the cutting table 601. One of the alloy sleeves 602 has an L-shaped inner wall and an L-shaped abutment 603 is correspondingly provided to this L-shaped structure for clamping angle steel. A screw 604 is rotatably connected to the upper surface of the abutment 603, and the screw 604 is threadedly connected to the alloy sleeve 602. The inner wall of the other alloy sleeve 602 is fixedly installed with… An L-shaped electromagnet 605 is used to attract the other end of the angle steel. A gear 606 is fixedly mounted on the circumferential surface of an alloy sleeve 602 on which the electromagnet 605 is installed. A rack 607 is fixedly mounted on the inner wall of the frame 1. The gear 606 and rack 607 mesh together. A corrugated plate is installed between the cutting table 601 and the bearing platform 4 to shield against sand and gravel, preventing sand and gravel from entering the meshing point of the gear 606 and rack 607. Mechanical clamping is achieved through an adjustable screw 604 at one end. The electromagnet 605 at one end provides a reliable composite clamping force, ensuring that the workpiece does not shift during cutting and grinding. Simultaneously, the meshing design of the gear 606 and rack 607 allows the workpiece clamping mechanism to automatically rotate under drive, enabling simultaneous cutting and grinding and improving the efficiency of angle steel cutting and grinding. The central area of ​​the upper surface of the cutting table 601 has a sloping structure to assist in the return of abrasive particles, effectively guiding and collecting debris, abrasive, and other impurities generated during processing. The sloping structure utilizes gravity to automatically slide and collect waste, preventing its accumulation on the worktable and ensuring the cleanliness of the processing area. An arc-shaped rebound net 8 is fixedly installed on one side of the upper surface of the cutting table 601 to rebound abrasive particles generated during grinding. The arc-shaped rebound net 8 can rebound some of the high-speed ejected abrasive particles back to the workpiece surface or working area, increasing the effective impact frequency of the abrasive particles and improving grinding efficiency and media utilization.

[0020] The moving mechanism 5 includes a rodless cylinder 501 fixed along the width of the support platform and two guide rods 502. The rodless cylinder 501 is located between the two guide rods 502 and a moving base 503 is slidably sleeved along the two guide rods 502. The moving base 503 is fixedly connected to the sliding block of the rodless cylinder 501. The bottom surface of the cutting table 601 is slidably connected to the upper surface of the moving base 503 through a self-locking slide rail. The cutting table 601 slides along the length of the moving base 503. A pull rod is fixedly installed on one side of the cutting table 601, which allows the operator to pull out the cutting table 601 through the pull rod, making it easy to remove the angle steel after grinding. Through the cooperation of the rodless cylinder 501 and the guide rods 502, the moving base 503 achieves smooth linear movement, ensuring precise control of the workpiece position during cutting and grinding. The cutting table 601 can slide along the moving base 503 and be pulled out through the pull rod, making it easy for the operator to safely and conveniently pick up and put away the angle steel, improving the convenience and safety of operation.

[0021] The recirculation grinding assembly 7 includes a recirculation hopper 701 fixedly installed on the inner wall of the frame 1. The inner bottom wall of the recirculation hopper 701 has a sloping structure for guiding the gravel. A storage tank 702 is fixedly installed on the inner bottom wall of the frame 1. The bottom of the recirculation hopper 701 is connected to the storage tank 702 via a pipe 703. An air compressor connector 704 is fixedly installed on the inner top wall of the frame 1. The air compressor connector 704 is fixedly connected to an external air compressor. The input end of the air compressor connector 704 is connected to the storage tank 702 via a pipe 705, and the output end of the air compressor connector 704 is fixedly connected to a... The three-way pipe 706 has two fixedly connected sandblasting nozzles 707 at its two output ends, which are used to spray sand and gravel to grind angle steel. The bottom wall of the sloping backflow hopper 701 can automatically guide the used sand and gravel to the storage box 702, realizing the recycling and reuse of sand and gravel. The air compressor connector 704 sucks in the sand and gravel in the storage box 702 and sends it to the sandblasting nozzles 707 through the three-way pipe 706 for circulating spraying, forming a closed-loop sandblasting and grinding system, which effectively reduces sand and gravel consumption, improves resource utilization, and ensures the continuity and stability of the grinding process.

[0022] The cutting assembly 2 includes a cutting spindle 201 rotatably connected to the inner wall of the frame 1. One end of the cutting spindle 201 passes through the frame 1. A cutting blade 202 is fixedly installed on the circumferential surface of the cutting spindle 201. The cutting blade 202 is positioned corresponding to the central area of ​​two alloy sleeves 602. The drive mechanism 3 includes a servo motor 301 fixedly installed on the upper surface of the frame 1. The output end of the servo motor 301 is connected to the synchronous belt drive via a synchronous pulley at the end corresponding to the cutting spindle 201. An adjusting pulley 302 for adjusting the tension of the synchronous belt is also installed on one side of the frame 1. The adjusting pulley 302 can be adjusted in position. A protective cover for the drive mechanism 3 is installed on one side of the frame 1. The servo motor 301, in conjunction with the synchronous belt drive, enables the cutting spindle 201 to move smoothly and control its speed. The adjustable tension pulley design allows the synchronous belt to be re-tensioned after long-term use due to stretching, thus maintaining high transmission efficiency and preventing slippage.

[0023] The working principle of this invention is as follows: Before starting the equipment, check that the amount of gravel in the storage tank 702 is sufficient, and that the air compressor connector 704 and servo motor 301 are in standby mode. Then, open the door panel on the side of the frame 1 to reserve operating space for clamping the workpiece. Then, the operator pulls the cutting table 601 along the length of the moving base 503 to a position that is easy to operate using the pull rod. Insert one end of the angle steel into the alloy sleeve 602 with the electromagnet 605 installed. When the electromagnet 605 is energized, it uses its L-shaped adsorption surface to firmly adsorb one end of the angle steel. At the same time, insert the other end of the angle steel into the alloy sleeve 602 on the opposite side. Rotate the screw 604 that is threaded to the sleeve to drive the L-shaped contact member 603 to move downward, pressing the other end of the angle steel from above. Through electromagnetic adsorption at one end and mechanical clamping at the other end, a compound clamping force is formed to ensure that the angle steel does not shift during subsequent processing.

[0024] When the door is closed and the equipment is started, the equipment's control system controls the spindle of the servo motor 301 to rotate. The servo motor 301 drives the cutting spindle 201 to rotate via a synchronous pulley and synchronous belt, causing the cutting blade 202 to rotate at high speed. The rodless cylinder 501 drives the motion base 503 to move linearly along the two guide rods 502, causing the entire adaptation mechanism 6 and the clamped angle steel to be smoothly fed towards the cutting blade 202. When the angle steel is conveyed to the position of the cutting blade 202 by the moving mechanism 5, the cutting blade 202 cuts the angle steel. This rotation action is completed synchronously during the conveying process without any additional pause. During the rotation of the angle steel, the control system controls the external air compressor to start, and draws gravel from the storage tank 702 through the air compressor connector 704. Compressed air and gravel are delivered to the two sandblasting nozzles 707 through the three-way pipe 706. The two sandblasting nozzles 707 are respectively aimed at the cut surface of the angle steel. At both ends, abrasive is sprayed simultaneously for grinding, achieving synchronous processing of both ends of the angle steel cut. The arc-shaped rebound mesh 8 on the upper surface of the cutting table 601 can rebound some of the high-speed sprayed abrasive back to the workpiece surface, increasing the effective impact frequency of the abrasive and improving grinding efficiency. The abrasive and waste falling during the grinding process automatically slide down using the sloping structure in the central area of ​​the upper surface of the cutting table 601, passing through the multi-holeed area of ​​the bearing platform 4, and falling into the return bucket 701. The sloping structure on the bottom wall of the return bucket 701... The structure guides the gravel to one side and transports it to the storage tank 702 through pipe 703, realizing the recycling of the gravel. The air compressor connector 704 continuously draws gravel from the storage tank 702 through pipe 705, forming a continuous grinding operation. After the processing is completed, the rodless cylinder 501 returns the moving base 503 and the cutting table 601 to the initial position. The operator opens the door panel, pulls the cutting table 601 out again through the pull rod, disconnects the electromagnet 605 and releases the screw 604, and removes the processed angle steel.

[0025] This invention discloses an integrated cutting and grinding device for hardware parts. When the angle steel is transported to the cutting mechanism via a moving mechanism 5, the angle steel rotates to assist in cutting. Simultaneously, a return grinding mechanism sandblasts and grinds the cut surface of the angle steel, achieving integrated cutting and grinding operations. This eliminates the need for inter-process transfer and secondary clamping time, improving processing efficiency. Crucially, two sandblasting nozzles 707 simultaneously spray gravel onto the two cut surfaces formed after the angle steel is cut, ensuring that both cut surfaces of the separated angle steel achieve the same degree of smoothness, guaranteeing consistent cross-sectional quality, and avoiding asymmetry where one end is sufficiently ground while the other is not. During this process, the ramp and return hopper 701 automatically recycle and reuse the gravel, supporting continuous grinding operations. All mechanisms work in tandem, simultaneously completing cutting and double-end grinding within the integrated workstation, achieving efficient continuous processing.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
