Description

Technical Field

[0001] The invention relates to the technical field of hardware processing, in particular to a cutting and grinding device for hardware processing. Background Art

[0002] Hardware processing is a key process in the manufacturing industry that uses mechanical means to process metal and other raw materials into various parts, covering cutting, forming, welding, grinding and other links. The cutting technology in hardware processing covers core processes such as turning, milling, and drilling, which accurately remove metal raw materials to achieve high-precision processing of complex shapes such as shafts, planes, and holes. The flattening process is centered on abrasive tools such as grinding wheels and sandpaper, and gradually reduces the surface roughness through progressive treatment of coarse grinding, fine grinding, and polishing.

[0003] Upon investigation, the Chinese invention patent with publication number CN109396859A discloses hardware processing equipment, including a machine base with a processing hole horizontally provided on the machine base, an upper chamber, a lower chamber and a grinding chamber provided in the machine base, and the processing hole is located between the upper chamber and the lower chamber; a cutting tool is provided in the upper chamber, and the lower part of the cutting tool extends above the processing hole; both the lower chamber and the grinding chamber are provided with lifting mechanisms, the lifting mechanism in the lower chamber is provided with a first fixed claw capable of fixing the pipe fitting, and the lifting mechanism in the grinding chamber is provided with a second fixed claw capable of fixing the pipe fitting, and the first fixed claw and the second fixed claw both extend into the processing hole; the upper end of the grinding chamber is connected to the processing hole, the second fixed claw is located in the grinding chamber, and frustum-shaped grinding blocks are provided on both sides of the grinding chamber, and the grinding blocks are provided with sandpaper, which can both cut and grind the pipe fittings.

[0004] However, when cutting hardware, especially when carving patterns on its outer wall, burrs are often left on its surface after cutting. If the burrs are not removed in time, it will directly affect the effect of texture cutting on the hardware and the accuracy of subsequent processing. In addition, hardware is usually small in size and has a complex shape with many gradient changes, which will put higher requirements on grinding accuracy. Ordinary grinding discs are large in size and are not suitable for grinding hardware with multiple corners. In addition, for some continuous production operations, the workpiece often needs to be extended to a certain length for cutting. However, the longer the extended part, the greater the impact of the pressure on the end of the workpiece during cutting, and it may even cause the workpiece to break and splash during feed, causing production accidents and posing a safety hazard.

The grinding belt 38 is small in width, vertical and long, and can adapt to complex workpieces of different sizes. Due to the movement of the stationary workpiece, the grinding position is consumed quickly. When replacing, the drive motor 36 is started to drive the grinding belt 38 to be pulled out from the winding box 37, so as to achieve quick replacement and avoid frequent shutdowns.

[0022] Reference Figure 4-6 The winding assembly includes a winding shaft 41 rotatably mounted in the winding box 37. The winding box 37 is provided with an opening 4.

A fixing plate 73 is fixedly mounted on the end of the sliding rod 64 away from the fixed ring 63. Three guide plates 72 that are compatible with the fixing plate 73 are fixedly mounted on the fixed ring 63. An operating rod 74 is rotatably mounted on the end of the bevel gear 2 71 away from the fixed ring 63. When processing long hardware, the bevel gear 2 71 is rotated by the operating rod 74 to drive the bevel gear 1 7, so that the sliding rod 64 slides into the fixed ring 63. The three sets of pulleys 65 synchronously clamp the workpiece 21, allowing it to rotate freely and the far end can be supported, so that the workpiece 21 remains stable and the cutting accuracy is improved.

[0024] Reference Figure 9 The buffer mechanism includes a wheel groove 8 opened at one end of the sliding rod 64 near the pulley 65, and sliding grooves 81 are symmetrically opened on the sliding rod 64 at positions on both sides of the wheel groove 8. A slide plate 82 is slidably installed in the sliding groove 81, and the slide plate 82 is rotatably connected to the pulley 65.

The slide plate 82 slides to act as a buffer. When installed in place, the spring 3 88 causes the impact ball 87 to pop out of the impact hemispherical hole 85 to issue a reminder, so that the operator can clearly understand the installation position and ensure that the workpiece 21 is properly fixed.

[0025] Reference Figure 1-3 , a rack 9 is fixedly mounted on the movable block 23 near the grinding belt 38, a gear rack 91 is fixedly mounted on the mounting arm 32 near the rack 9, a gear 92 meshing with the rack 9 is rotatably mounted on the gear rack 91, a T-slot 93 is provided at the bottom of the mounting plate 3, a T-block is slidably mounted in the T-slot 93, a rack 2 94 meshing with the gear 92 is fixedly mounted at the bottom of the T-block, a connecting block 95 is fixedly mounted on one end of the rack 2 94 near the workpiece 21, a cleaning arm 96 is symmetrically rotatably mounted on the connecting block 95, a torsion spring is provided between the cleaning arm 96 and the connecting block 95; a chip storage groove is provided in the machine tool 1, a chip drop port 97 is provided on the machine tool 1, and a chip collection box 98 is slidably mounted in the chip storage groove; When the grinding belt 38 moves to the workpiece 21, it drives the gear 92 to move along the rack 1 9, causing the rack 2 94 to move twice the distance relative to the workpiece 21. When the grinding belt 38 moves to the middle of the machine tool 1, the rack 2 94 drives the cleaning arm 96 to the distal chip drop port 97 to push the debris into the chip storage trough. When resetting, the cleaning arm 96 sweeps back and cleans the debris to the proximal chip drop port 97 and drops it into the chip storage trough. After the processing is completed, the chip collection box 98 is used to remove the debris for recycling, thereby achieving synchronous chip cleaning during processing and protecting the normal use of the equipment.

[0026] The specific working principle of the present invention is as follows: When in use, the workpiece 21 is clamped on the mounting frame 2 on the machine tool 1, the workpiece 21 is driven to rotate, and the movable block 23 is moved along the slide rail 22 to the required processing position as needed. The position of the cutting knife 26 is adjusted by the movable plate 25 to cut the workpiece. At the same time, the movable block 23 on the other side is moved to the same position. Under the drive of the telescopic rod 31, the mounting plate 3 can move toward the workpiece 21, and the grinding belt 38 is brought close to the workpiece 21 to grind the workpiece flat and remove the burrs generated by cutting in time. The width of the grinding belt 38 is small, so the grinding belt 38 can adapt to various shapes and complex structures. The hardware workpiece 21 can be smoothed by moving the grinding belt 38 to the corresponding position as needed. At the same time, the grinding belt 38 is vertically arranged and has a long length, which can adapt to workpieces 21 of different sizes. Since the grinding belt 38 is stationary and the workpiece 21 moves relative to the grinding belt 38, the position of the grinding belt 38 used for grinding is consumed quickly. When it needs to be replaced, it is only necessary to start the drive motor 36. The motor rotates and drives the grinding belt 38 to be pulled out from the winding box 37 along the roller 34, thereby realizing rapid replacement of the grinding belt 38, facilitating continuous processing operations, and avoiding the problem of frequent shutdown and replacement due to consumption of the grinding belt 38. When the grinding belt 38 is grinding, the workpiece 21 does not contact the grinding belt 38 at the beginning. At this time, the spring 1 46 pulls the pawl 43 and drives the ratchet 42 to the position of the baffle 47. When the workpiece 21 contacts and squeezes the grinding belt 38, under the action of the workpiece 21, the grinding belt 38 drives the reel 41 to rotate and drives the ratchet 42 to rotate, pushing the pawl 43 to the position of the limit post 44. At this time, by releasing a small section of the grinding belt 38, the grinding belt 38 can surround the workpiece 21 in a certain arc, thereby increasing the grinding area and improving the grinding efficiency. At the same time, it protects the grinding belt 38 from being separated from the cutting blade 26 to ensure the safety of processing. When the grinding belt 38 needs to be replaced, the magnet 52 is turned. After the magnet 52 switches its position, it is attracted by the limiting post 44 formed by the magnet. The limiting post 44 slides into the yield groove 5 under the action of the magnetic force. At this time, the pawl 43 is no longer limited by the limiting post 44. The reel-up shaft 41 can drive the ratchet 42 to rotate, while releasing the grinding belt 38. The used grinding belt 38 is reeled to the output end by the driving motor 36. When the replacement is completed, the pawl 43 is reset under the action of the spring 46, and the magnet 52 slides to the other end. At this time, the relative magnetic poles of the magnet 52 and the limiting post 44 are switched. Under the action of the repulsive force, the limiting post 44 pops out of the yield groove 5, and the limit of the pawl 43 is restored, so that the consumables can be replaced conveniently, quickly and safely, thereby improving the processing efficiency. When the length of the hardware to be processed is long, the bevel gear 2 71 can be rotated by the operating rod 74 to drive the bevel gear 1 7 to rotate, and then the sliding rod 64 is driven to slide into the fixing ring 63. The three sets of pulleys 65 jointly form a clamping effect on the workpiece 21. Under the action of the pulley 65, the workpiece 21 can rotate freely. At the same time, the far end of the workpiece 21 is supported by the sliding rod 64 and the pulley 65 to ensure the stability and safety of the processing, maintain the stability of the workpiece 21 and improve the processing accuracy. When the pulley 65 contacts the workpiece 21 during adjustment, it drives the slide plate 82 to slide and compresses the spring 2 83. When the slide plate 82 contacts the limit block 84, the fixation is completed. The slide plate 82 slides relative to the sliding groove 81 to provide a certain buffering effect during installation, avoiding hard contact with the workpiece 21 and causing damage to the workpiece 21. When it is installed in place, under the action of the spring 3 88, the impact ball 87 pops out and hits the hemispherical hole 85, making a crisp sound, which can remind the operator to install it in place and ensure that the workpiece 21 is properly fixed. When the grinding belt 38 moves to the workpiece 21, by driving the gear 92 to rotate and move along the rack 1 9, the rack 2 94 can move twice the distance relative to the gear 92. Therefore, when the grinding belt 38 moves to the middle of the machine tool 1, the rack 2 94 drives the cleaning arm 96 to move to the chip drop port 97 at the far end, pushing the debris on the machine tool 1 into the chip storage groove. When the grinding belt 38 is processed and reset, the cleaning arm 96 sweeps back and cleans the debris to the chip drop port 97 at the near end and drops it into the chip storage groove. When the processing is completed, the debris can be taken out through the chip collection box 98 for recycling and processing, thereby realizing the cleaning of the debris simultaneously with the processing, ensuring that the debris will not remain and accumulate, protecting the normal use of the equipment, and the cleaning arm 96 can rotate to avoid it when encountering the connecting plate 62, and then reset under the action of the torsion spring, thereby ensuring the safety of use.
