Description

Technical Field

[0001] This invention relates to the field of rubber product manufacturing, specifically a dual-station servo cutting machine for rubber sleeves. Background Technology

[0002] In the automated processing of rubber sleeves (such as rubber tubes and rubber bushings), the cutting process is one of the key steps. Traditional rubber sleeve cutting equipment mostly adopts a single-station structure, resulting in low processing efficiency and difficulty in meeting the needs of mass production. Furthermore, due to the high elasticity and flexibility of rubber materials, deformation, misalignment, or tool jamming easily occur during cutting, leading to uneven cuts, poor dimensional accuracy, and even damage to the tool or workpiece. While some existing cutting devices attempt to improve cutting quality using rotary cutting or auxiliary support, they are often structurally complex, inconvenient to adjust, and unable to apply stable and controllable tension to the rubber sleeve during cutting, resulting in high cutting resistance and rapid tool wear. Therefore, we provide a dual-station servo cutting machine for rubber sleeves. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-station servo cutting machine for rubber sleeves to solve the problems mentioned in the background art.

[0004] The technical problem solved by this invention is: The present invention can be achieved by the following technical solution: a dual-station rubber sleeve servo cutting machine, including a mounting base plate, a feeding block driven by a lead screw is symmetrically arranged on one side of the top of the mounting base plate, a transmission box is fixed in the middle of the top of the mounting base plate, and a clamping component for fixing the rubber tube is symmetrically and rotatably installed through the side wall of the transmission box. The transmission box has a cutting assembly that slides up and down on its top. The cutting assembly uses a cutting wire to cut the rubber sleeve. A vertical plate is fixed on the side of the mounting base away from the feeding block. Auxiliary support components are symmetrically installed on the vertical plate. The auxiliary support components are used to support and tension bend the cut part of the rubber sleeve. The clamping assembly, auxiliary support assembly, and feeding block are coaxially arranged.

[0005] A further technical improvement of the present invention is that: the clamping assembly includes a follower sleeve that rotates with the transmission box, and a driven gear is coaxially fixed on the outer periphery of the follower sleeve, and the driven gear meshes with a drive gear on the rotatably mounted transmission box; Two clamping plates are symmetrically arranged inside the follower sleeve. A wedge-shaped adjusting block is floatingly arranged on the back of the clamping plate and located outside the follower sleeve. A horizontally adjustable limiting ring is fitted on the outside of the follower sleeve, and the inner side of the limiting ring contacts the top inclined surface of the wedge-shaped adjusting block.

[0006] A further technical improvement of the present invention is that: the back of the clamp plate passes through the follower sleeve through a connecting pin and is fixed to the wedge-shaped adjusting block; a compression spring is sleeved on the outer periphery of the connecting pin, and the two ends of the compression spring abut against the wedge-shaped adjusting block and the follower sleeve, respectively.

[0007] A further technical improvement of the present invention is that the cutting assembly includes a lifting plate that slides with the transmission box. The side wall of the lifting plate is provided with an arc groove, and a roller is rolled in the arc groove. The roller is driven to move by a lead screw assembly installed on the top of the transmission box. Each time the roller travels through a complete arc groove, it completes one feed, cutting and retraction operation.

[0008] A further technical improvement of the present invention is that: the auxiliary support assembly includes an electric cylinder fixed to the upright plate, the output end of the electric cylinder is coaxially fixed to a support column, a support head is provided on the side of the support column away from the electric cylinder, and a rotating sleeve is rotatably sleeved on the outer periphery of both the support column and the support head. A connecting shaft 1 and a connecting shaft 2 are provided between the support column and the support head. One end of the connecting shaft 1 is fixed to the support column and the other end is hinged to the support head. One end of the connecting shaft 2 is hinged to the support column and the other end is hinged to a slider that is slidably disposed on the side wall of the support head. An electric actuator is hinged between the connecting shaft 1 and the connecting shaft 2.

[0009] A further technical improvement of the present invention is that: a feeding ring is provided on the outer side of the rotating sleeve, and a plurality of floating support rods are evenly arranged on one side of the feeding ring, with the two ends of the floating support rods being fixed to the feeding ring and the upright plate respectively.

[0010] A further technical improvement of the present invention is that a protrusion is provided on one side of the top arc surface of the feeding block, and the protrusion is used to axially limit the end of the rubber sleeve.

[0011] A further technical improvement of the present invention is that the rotating sleeve allows the rubber sleeve to rotate relative to the support head and support column during the rotation process, so that the direction of the bending tension on the rubber sleeve remains constant, and the direction of the bending tension on the rubber sleeve at each circumferential angle position is towards the cutting wire.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up an auxiliary support component and using an electric actuator to drive the support head to deflect, generates a controllable constant tension in the rubber sleeve at the cutting point, preventing deformation or displacement of the rubber sleeve during the cutting process; at the same time, when the rubber sleeve rotates, rotating sleeve one and rotating sleeve two rotate relative to the support column and support head, so that the tension direction is always upward and remains constant, significantly reducing cutting resistance, eliminating the jamming phenomenon, and ensuring the flatness and dimensional accuracy of the cut.

[0013] 2. This invention adopts a dual-station symmetrical layout, combined with a servo-driven feeding screw, an electromagnetically driven clamping assembly, and a cutting assembly controlled by the screw assembly. It can automatically complete the entire process of feeding, axial limiting, centering and clamping, rotation, tension application, cutting and unloading of the rubber sleeve. The dual stations work synchronously, which greatly improves processing efficiency and meets the needs of mass production.

[0014] 3. The clamping assembly of this invention, through the cooperation of a wedge-shaped adjusting block and a compression spring, adapts to rubber sleeves of different pipe diameters and achieves stable central clamping. During cutting, the clamping assembly drives the rubber sleeve to rotate at a uniform speed, which, in conjunction with the feed of the cutting assembly, achieves a stable machining method similar to lathe cutting, ensuring the roundness and perpendicularity of the cut surface.

[0018] To further illustrate the technical means and effects of the present invention in achieving the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0019] Please see Figure 1-5 As shown, the dual-station rubber sleeve servo cutting machine includes a mounting base 1. Feeding blocks 2 are symmetrically slidably mounted on one side of the top of the mounting base 1. A feeding screw 3, mounted on the top of the mounting base 1 via a support, is provided between the two feeding blocks 2. The feeding screw 3 is driven by a motor (not shown in the figure). The screw nut of the feeding screw 3 is fixedly connected to the feeding blocks 2 on both sides. A protrusion on one side of the top arc surface of the feeding block 2 provides axial limitation for the end of the rubber sleeve, thereby driving the feeding block 2 to move horizontally under the transmission action of the feeding screw 3. A transmission box 4 is fixed at the top center of the mounting base plate 1. Clamping components 5 are symmetrically and rotatably mounted through the side wall of the transmission box 4. A drive gear 6 is rotatably mounted on the side wall of the transmission box 4 between the two clamping components 5. The drive gear 6 is driven by a motor, which in turn causes the two clamping components 5 to rotate relative to the transmission box 4. Specifically, the clamping assembly 5 includes a follower sleeve 501 that rotatably engages with the transmission box 4. A driven gear 502 is coaxially fixed to the outer periphery of one side of the follower sleeve 501. The driven gear 502 meshes with the drive gear 6 for transmission. Two clamping plates 503 are symmetrically arranged inside the follower sleeve 501. The back of each clamping plate 503 passes through the follower sleeve 501 through two connecting pins, and a wedge-shaped adjusting block 504 is fixedly installed at one end of the pins. A compression spring 505 is provided on the outer periphery of the connecting pins, and the two ends of the compression spring 505 abut against the wedge-shaped adjusting block 504. The follower sleeve 501 is fitted with a limiting ring 506 on its outer side. Under the action of the compression spring 505, the inner side of the limiting ring 506 is always in contact with the top inclined surface of the wedge-shaped adjusting block 504. The limiting ring 506 is driven by an electromagnetic drive assembly 507 on one side. The electromagnetic drive assembly 507 is fixed on the transmission box 4. The electromagnetic drive assembly 507 is arranged in a ring shape and is coaxial with the limiting ring 506. Specifically, the electromagnetic drive assembly 507 controls the contact position with the wedge-shaped adjusting block 504 by extending and retracting its output end through electromagnetic force.

[0020] A cutting assembly 7 is slidably mounted on the top of the transmission box 4. The cutting assembly 7 includes a lifting plate 701 that slides with the transmission box 4. An arc groove 702 is provided on the upper side wall of the lifting plate 701. A roller 703 is rolled in the arc groove 702. The roller 703 is rotatably mounted on the output end of the lead screw assembly 8. The lead screw assembly 8 is fixed on the top of the transmission box 4. Two wire winding rollers 704 driven by a motor are symmetrically mounted on the bottom two sides of the lifting plate 701. Cutting wire 705 is wound and connected to the two wire winding rollers 704. During rotation, the cutting wire 705 is kept under tension by the motor damping to cut the rubber sleeve. A coolant nozzle 706 is provided above the cutting wire 705 between the two wire winding rollers 704 for spraying coolant during the cutting operation.

[0021] A vertical plate 9 is fixedly installed on the side of the mounting base plate 1 away from the feeding block 2. Auxiliary support components 10 for assisting in the rubber sleeve cutting operation are symmetrically installed on the vertical plate 9. Each auxiliary support 10 includes an electric cylinder 1001 fixedly installed on one side of the vertical plate 9. A support column 1002 is coaxially fixedly installed on the output end of the electric cylinder 1001. A rotating sleeve 1003 is rotatably sleeved on the outer periphery of the support column 1002. A support head 1004 is coaxially provided on the end of the support column 1002 away from the electric cylinder 1001. A rotating sleeve 2 1005 is rotatably sleeved on the outer periphery of the support head 1004. A connecting shaft 1006 and a connecting shaft 1007 are provided between the support head 1004 and the support column 1002. The connecting shaft 1006 is horizontally arranged, with one end fixed to the support column 1002 and the other end hinged to the support head 1004. One end of the connecting shaft 1007 is hinged to the support column 1002, and the other end is hinged to a slider 1009 that is slidably disposed on the side wall of the support head 1004. An electric actuator 1008 is provided between the connecting shaft 1006 and the connecting shaft 1007. Both ends of the electric actuator 1008 are respectively hinged to the middle of the two connecting shafts. When the output end of the electric actuator 1008 extends, the connecting shaft 1007 pushes the slider 1009 to slide on the side wall of the support head 1004, thereby causing the support head 1004 to deflect around the connecting shaft 1006.

[0022] A feeding ring 1010 is also provided on the outside of the rotating sleeve 1003. Multiple floating support rods 1011 are evenly arranged on one side of the feeding ring 1010. The two ends of the floating support rods 1011 are fixedly connected to the feeding ring 1010 and the vertical plate 9, respectively. The floating support rods 1011 can be elastic telescopic rods with spring action.

[0023] It should be noted that the clamping component 5 is coaxially arranged with the corresponding auxiliary support component 10 and the feeding block 2.

[0024] When using this invention, the rubber tube to be cut is placed between the feeding block 2 and the two clamping plates 503 in the clamping assembly 5. The feeding screw 3 drives the feeding block 2 to move towards the transmission box 4 until it comes into contact with the unloading ring 1010. At this time, the electromagnetic drive assembly 507 drives the limiting ring 506 to move and cooperate with the wedge-shaped adjusting block 504, so that the two clamping plates 503 move towards each other to clamp and fix the rubber sleeve. Subsequently, the output end of the electric cylinder 1001 extends a certain distance, and its support head 1004 and support column 1002 both enter the front end of the rubber sleeve; then the electric push rod 1008 moves to make the support head 1004 deflect in a fixed direction, so that the rubber sleeve is tensioned in the opposite direction of its deflection, making it easier to cut in subsequent cutting operations and preventing the blade from jamming. Subsequently, the drive gear 6 rotates, causing the driven gear 502 to rotate, which in turn causes the follower sleeve 501 to rotate along with the rubber tube. Then, the lead screw assembly 8 drives the cutting assembly 7 to move down to cut the rubber tube. Each roller 703 completes the stroke of the arc groove 702, completing the cutting and tool lifting operations. During the cutting process, the cutting wire moves at high speed 705. It should be noted that, due to the presence of the rotating sleeve, the rubber sleeve rotates relative to the support head 1004 and the support column 1002 during rotation. Thus, the tension of the rubber sleeve and the bending of the rotating sleeve remain constant. However, the rubber sleeve will bend under tension at each circumferential position during rotation, which facilitates cutting. The direction of tension bending is always upward.

[0025] After the cutting is completed, the output end of the electric cylinder 1002 retracts, and the cut rubber sleeve moves under the action of friction. However, the presence of the feeding ring 1010 prevents it from moving completely synchronously. Finally, after losing support, it falls into the feeding groove 101 opened on the mounting base plate 1 below.

[0026] Release the clamps 503 from the rubber sleeve, continue to drive the feeding block 2 to feed the material, and repeat the above steps to carry out the next round of cutting.

[0027] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
