Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware processing technology, specifically to a hardware processing equipment. Background Technology
[0002] As is well known, hardware accessories refer to machine parts or components made of metal, as well as some small hardware products. They can be used independently or as auxiliary tools. For example, metal pipes and plastic pipes are commonly used in production for gas and liquid transmission pipelines. Metal pipes have advantages such as long service life and sturdiness, so they have a wide range of applications.
[0003] Currently, commonly used metal pipe cutting devices have certain shortcomings when cutting thin-walled pipes or small-diameter rods. Traditional cutting devices often use a handheld handle to press the cutting blade or a telescopic rod to move the blade towards the fixed pipe, then continuously apply pressure to a section of the pipe to cut it. In this cutting mode, the pipe is prone to extrusion deformation. Once the pipe is deformed, the end loses its required flatness and precision, failing to meet actual usage requirements, and often necessitates secondary processing to correct the end.
[0004] Therefore, developing a new type of metal pipe cutting device that can adjust the cutting position of the workpiece is of great practical significance and market demand. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a hardware processing equipment that effectively prevents thin-walled pipes and other components from being squeezed and deformed during the cutting process.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a hardware processing equipment, including a base and a cutting device. A support is provided on the base, and a sleeve is rotatably installed on the support. The sleeve is installed on one side of the cutting device, and the end of the sleeve near the cutting device is at a certain distance from the cutting device along the axial direction. A hollow cavity is provided inside the sleeve, through which the workpiece is passed. A fixing component is provided on the wall of the sleeve for fixing the workpiece inside the cavity. During installation, the workpiece is installed in the cavity inside the sleeve, and the cutting position of the workpiece is aligned with the cutting device. The fixing component is used to fix the workpiece. During cutting, rotating the sleeve synchronously drives the workpiece to rotate, so that the cutting device cuts the circumference of the workpiece.
[0009] (III) Beneficial Effects
[0010] Compared with the prior art, the present invention provides a hardware processing equipment, which has the following beneficial effects:
[0011] This hardware processing equipment installs the workpiece inside the cavity of the sleeve, rotates the top ribbon to move the fixing plate, and fixes the workpiece in place with the sleeve. Then, the sleeve is rotated so that the sleeve and the workpiece rotate synchronously to achieve circumferential cutting. This also makes the cutting force evenly distributed on the circumference of the workpiece, avoiding continuous extrusion pressure on the same part of the workpiece and reducing the extrusion deformation problem of easily deformable workpieces such as thin-walled pipes during the cutting process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] In the prior art, a hardware processing equipment includes a base 1 and a cutting device 2. The cutting device 2 includes a hydraulic cylinder, and a housing is fixedly installed at the lower part of the hydraulic cylinder. A cutting blade is rotatably connected inside the housing. The cutting blade is driven by a motor. When the motor rotates, it drives the cutting blade to rotate. Then the hydraulic cylinder extends and drives the cutting blade to approach the workpiece 5. After contacting the workpiece 5, it cuts it. A discharge groove is provided on the base 1, and the processed workpiece 5 and debris can be discharged from the discharge groove.
[0023] Please see Figure 1-8 This utility model discloses a hardware processing equipment. A protective cover 13 is provided on the base 1. The cutting device 2 can be installed on the protective cover 13 or on the base 1. The appropriate installation position can be selected according to actual needs. A support member 3 is provided on the base 1. The support member 3 has a smooth opening with the same outer diameter as the sleeve 4. The sleeve 4 can rotate in the opening. Alternatively, other rotating devices can be used for connection. For example, the sleeve 4 can rotate on the support member 3 through a bearing. The sleeve 4 is installed on one side of the cutting device 2.
[0024] The sleeve 4 has a hollow cavity inside, through which the workpiece 5 passes. The workpiece 5 can be a metal tube, a metal rod, or a plastic tube. The workpiece 5 is installed by passing it through the cavity of the sleeve 4, and the cutting position of the workpiece 5 is aligned with the cutting device 2. In the subsequent cutting process, the cutting device 2 cuts at the cutting position.
[0025] The end of the sleeve 4 closest to the cutting device 2 is at a certain distance from the cutting device 2 along the axial direction. When the cutting device 2 cuts the workpiece 5, the speed of the tool is usually very fast. If the sleeve 4 is too close to the cutting device 2, during the cutting process, the cutting device 2 may hit the sleeve 4 due to factors such as vibration of the workpiece 5, slight displacement of the cutting device 2, or operation error, which may damage the sleeve 4 and the cutting device 2. Setting a certain distance can effectively avoid this situation.
[0026] The protective cover 13 has a smooth circular hole on its side wall, which matches the size of the top block 17. The top block 17 rotates in the circular hole. Alternatively, other rotating devices can be used to rotate both parts. For example, the top block 17 can rotate on the side wall of the protective cover 13 via a bearing. After the workpiece 5 passes through the sleeve 4, when the end of the workpiece 5 rests against the top block 17 and no longer moves, the cutting position of the workpiece 5 is aligned with the cutting device 2. When the workpiece 5 rotates under the drive of the sleeve 4, one end of the workpiece 5 drives the top block 17 to rotate on the protective cover 13. A protrusion 18 is provided in the middle of the top block 17. When the end of the workpiece 5 rests against the top block 17, the protrusion 18 is inside the workpiece 5. The outer wall of the protrusion 18 is supported on the inner wall of the workpiece 5, which can improve the stability of the workpiece 5. When the cutting device 2 cuts the workpiece 5, it can reduce the shaking of the workpiece 5. The sleeve 4 has a fixing component on its wall for fixing the workpiece 5 inside the cavity.
[0027] During installation, the worker installs the workpiece 5 inside the cavity of the sleeve 4, aligns the cutting position of the workpiece 5 with the cutting device 2, and uses the fixing component to fix the workpiece 5, thereby fixing the processing frame inside the sleeve 4 in conjunction with the sleeve 4.
[0028] During cutting, the rotating sleeve 4 synchronously drives the workpiece 5 to rotate, so that the cutting device 2 cuts the circumference of the workpiece 5. This causes the area where the cutting device 2 applies pressure to the workpiece 5 to change as the workpiece 5 moves in a circular motion, preventing the same area of the workpiece 5 from being continuously squeezed and cut by the cutting device 2, thus improving the quality of the workpiece 5 after processing to a certain extent.
[0029] Please see Figure 4 , Figure 7 and Figure 8 The fixing component includes a support frame 6 mounted on the sleeve 4. The support frame 6 has a threaded hole with an internal thread. A set screw 7 is connected to the internal thread of the threaded hole. The set screw 7 has an external thread that matches the internal thread of the threaded hole. A fixing plate 8 is rotatably mounted on the lower part of the set screw 7. When the worker passes the workpiece 5 through the sleeve 4 and makes the end of the workpiece 5 abut against the top block 17, it can be fixed to the top of the set screw 7 with a wrench or other device. Then, it is rotated forward so that the set screw 7 rotates in the threaded hole of the support frame 6, and at the same time, it drives the fixing plate 8 to move closer to the workpiece 5 until the fixing plate 8 is pressed against the outer wall of the workpiece 5, which cooperates with the sleeve 4 to fix the workpiece 5, so that the sleeve 4 and the workpiece 5 are fixed together.
[0030] The sleeve 4 is provided with a through groove 9 for the fixing plate 8 to pass through. When the fixing plate 8 moves under the drive of the set screw 7, the fixing plate 8 passes through the through groove 9 of the sleeve 4 and then fixes the workpiece 5.
[0031] Please see Figure 3 and Figure 8 It also includes a drive motor 10, which transmits power to the sleeve 4 through a transmission component. The transmission component includes a meshing gear 11 and a gear 2 12. Gear 11 is mounted on the sleeve 4, and gear 2 12 is mounted on the motor shaft of the drive motor 10. When the operator starts the drive motor 10, the drive motor 10 drives gear 2 12 to rotate. When gear 2 12 rotates, it drives gear 11 to rotate. When gear 11 rotates, it drives the sleeve 4 and the machined part 5 inside the sleeve 4 cavity to rotate.
[0032] The transmission assembly can also consist of two pulleys connected by a belt. One pulley is mounted on the sleeve 4, and the other pulley is mounted on the motor shaft of the drive motor 10. When the drive motor 10 is started, it rotates, causing the pulley to rotate. The pulley then drives the belt to move, which in turn drives the pulley on the sleeve 4 to rotate, thereby causing the sleeve 4 and the workpiece 5 to rotate. The rotation of the sleeve 4 can also be achieved through other methods, such as the operator manually rotating the sleeve 4 to rotate the workpiece 5 inside.
[0033] Please see Figure 2-3 It also includes a clamping assembly, which consists of two clamping plates 14. One clamping plate 14 is fixedly connected to the cover 13 via a support rod, and the other clamping plate 14 is fixedly installed to the base 1 via a telescopic rod 15. When cutting the workpiece 5, the telescopic rod 15 drives the clamping plate 14 to move toward the workpiece 5, and the clamping plate 14 on the support rod clamps the workpiece 5 on the outer wall, generating a certain holding force to hold the workpiece 5, thus preventing the workpiece 5 from shaking during cutting.
[0034] Please see Figure 3 The inner wall of the clamping plate 14 is provided with a rolling groove and a rolling ball 16 is rolled on it. The rolling ball 16 is supported on the outer wall of the workpiece 5. When the workpiece 5 rotates, it rotates at the center of the clamping plate 14. The rotational force generated is transmitted to the rolling ball 16, causing the rolling ball 16 to roll in the rolling groove of the clamping plate 14. While supporting the workpiece 5, the rolling ball generates little friction with the workpiece 5, thereby reducing the wear caused by friction.
[0035] Please see Figure 3 The ball can roll in the groove of the clamping plate 14 under the drive of the workpiece 5 and play a supporting role. The contact area between the ball 16 and the workpiece 5 is small, which can reduce the friction. The ball 16 can be spherical or cylindrical, preferably spherical.
[0036] Please see Figure 5The protrusion can support the workpiece 5. After the workpiece 5 is cut, when the telescopic rod 15 moves the clamping plate 14 downward, the processing tube that is pressed against one end of the top block 17 begins to fall downward after losing the support of the clamping plate 14. The processing tube falls off the protrusion 18. The protrusion 18 can be hemispherical, cylindrical or conical, preferably hemispherical.
[0037] In summary, when using this hardware processing equipment, the operator aligns one end of the workpiece 5 with the opening of the sleeve 4, inserts it into the cavity of the sleeve 4 from the opening, moves it along the cavity, exits from the other end of the sleeve 4, and then passes through the middle of the clamping plate 14. The ball bearings in the groove of the clamping plate 14 support the outer wall of the workpiece 5 and roll within the groove as the workpiece 5 moves. When the end of the workpiece 5 abuts against the end face of the top block 17, the cutting part of the workpiece 5 aligns with the cutting device 2. The protrusion 18 in the middle of the top block 17 is inside the workpiece 5, and the outer wall of the protrusion 18 supports the inner wall of the workpiece 5. Then, the operator uses a wrench or other device to fix it in place. The top of the set screw 7 is rotated forward, causing it to rotate within the threaded hole of the support frame 6. Simultaneously, the fixing plate 8 moves closer to the workpiece 5, passing through the through groove 9 of the sleeve 4 during movement. One end of the fixing plate 8 then presses against the outer wall of the workpiece 5, generating a certain compressive force. After the sleeve 4 secures the workpiece, the wrench or other device is removed from the top of the set screw 7. The cutting device 2 can then be activated to cut the workpiece 5. Simultaneously, the drive motor 10 is activated, causing the second gear 12 to rotate. The second gear 12, in turn, drives the meshing gear 11 to rotate. The gear 11, in turn, drives the sleeve 4 and the cavity within the sleeve 4. The workpiece 5 rotates, causing the cutting device 2 to change position during the rotation. The cutting device 2 performs circumferential cutting on the workpiece 5. After the workpiece 5 is cut, the cutting device 2 is turned off, the drive motor 10 is turned off, and then the telescopic rod 15 is activated. The telescopic rod 15 retracts, causing the clamping plate 14 to move downward. At this time, the workpiece 5, which is located on one side of the top block 17 after cutting, tilts downward and falls due to the loss of support from the clamping plate 14. When the workpiece 5 tilts, it falls off the protrusion 18 and into the discharge groove. When the part of the workpiece 5 at one end of the clamping plate 14 collides with the clamping plate 14 on the telescopic rod 15, it blocks the downward movement of that part. The workpiece 5 continues to fall into the discharge chute without support until it is lower than the part near the clamping plate 14. At this point, the part near the clamping plate 14 slides off the clamping plate 14 and finally falls into the discharge chute and is placed outside for easy pickup by workers. Then, the workers activate the telescopic rod 15 in the reverse direction to extend it and move the clamping plate 14 upward until it contacts the clamping plate 14 of the support rod. The telescopic rod 15 then stops extending. At this point, the set screw 7 is rotated in the reverse direction to move the fixing plate 8 away from the workpiece 5. After the workpiece 5 is no longer clamped, its position can be adjusted again for installation, and then cutting can be performed.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
