Description

Technical Field

[0001] This invention relates to the field of fully automatic tube end processing technology, specifically a processing technology for automatically and quickly flushing the tube ends of towel racks. Background Technology

[0002] Towel racks are a common household item, mainly used for hanging towels and other bath products. They are usually made of materials such as copper, stainless steel, zinc alloy, and aluminum. In order to fix the towel rack to the wall and to hang and support bath products, the towel rack tubes generally need to be hollow and have both ends that can be easily fixed and connected to other towel rack tubes.

[0003] Currently, to ensure the internal cavities of all tubes in overlapping towel racks are interconnected and to reduce the overall weight of the towel rack, the manufacturing process requires the creation of holes, flanged bosses, and heightening / shaping at various tube ends. The industry currently uses traditional manual stamping to process these holes and flanged bosses. Traditional stamping processes are labor-intensive and have low production efficiency. To reduce labor intensity and improve production efficiency, a fully automated tube end punching and flanging device needs to be developed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a processing technology for automatically and quickly flipping the ends of towel rack tubes, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a processing technology for automatically and quickly flipping the ends of towel rack tubes, comprising: a frame platform, a receiving mechanism, a receiving bracket fixedly connected to the top of the receiving mechanism, towel rack tubes, and an electrical control system. The automatic and rapid flipping process for the ends of towel rack tubes includes the following steps:

[0008] Power control: The electrical control system powers the feeding mechanism and the punching and forming mechanism, and can be operated by the operator to control the feeding mechanism and the punching and forming mechanism.

[0009] Feeding: Feeding mechanisms are set on both sides of the machine frame platform. The feeding mechanisms simultaneously store and transport the towel rack tubes on both sides of the machine frame platform and place the towel rack tubes between the two punching and forming mechanisms located on both sides of the machine frame platform.

[0010] Forming: The two punching and forming mechanisms are dynamically adjusted according to the length of the towel rack tube. At the same time, the punching and forming mechanisms perform processing work such as punching, flanging, and height shaping on one end of the towel rack tube.

[0011] Feeding: The feeding mechanism delivers the finished towel racks into the collection end through a pipe.

[0012] Preferably, the feeding mechanism includes a storage trough plate fixedly connected to the top of the frame platform.

[0017] A2: The pusher cylinder is started by the control system, which pushes the pusher plate to move towards the towel rack tube, and then contacts the towel rack tube and drives the towel rack tube into the first contour groove;

[0018] A3: At the same time, the feeding card slot plate starts, which drives the towel rack tube located in the first contour slot of the positioning slot plate into the second contour slot.

[0020] Preferably, a receiving guide plate is rotatably connected to the side of the positioning groove plate away from the storage groove plate;

[0021] The towel rack feeding process includes the following steps:

[0022] C1: The feeding slot plate moves under the control of the electronic control system, moving the towel rack that is located in the second contour slot and processed to the top of the third contour slot using a tube;

[0023] C2: The towel rack located at the top of the third contour groove moves down the receiving guide plate to the top of the receiving mechanism and is collected by the receiving bracket.

[0024] Preferably, the top of the frame platform is fixedly connected to a die base fixing platform including the punching and forming mechanism, the top of the die base fixing platform is fixedly connected to a die core pushing cylinder, the output end of the die core pushing cylinder near the electrical control system is fixedly connected to a die core fixing seat, the top of the die core fixing seat is fixedly connected to a punch forming cylinder, the side of the die core fixing seat away from the die core pushing cylinder is fixedly connected to a core mold, the top inner side of the die core fixing seat is slidably connected to an upper module, and the bottom inner side of the die core fixing seat is fixedly connected to a die pre-assembly block, the die pre-assembly block is located directly below the upper module;

[0025] The process of forming tubing for towel racks includes the following steps:

[0026] B1: The upper module moves downward under the control of the electronic control system and clamps the towel rack tube located in the second contour groove together with the pre-assembled block;

[0027] B2: The mold core pushes the hydraulic cylinder to start and drives the mold core to be inserted into the towel rack tube, and works with the upper module to punch and form holes in the towel rack tube.

[0029] (III) Beneficial Effects

[0030] The automatic and rapid flushing process for the ends of towel rack tubes provided by this invention has the following beneficial effects:

[0031] 1. The automatic and rapid punching process of this towel rack tube end, through the operation of the pusher cylinder and the movement of the feeding slot plate, allows the towel rack tube to be pushed from the pusher cylinder to the slot and then punched and formed in the mold, completing one tube punching and forming cycle in about 10-15 seconds. Compared with the traditional stamping and forming time, it shortens the time by 5-10 seconds per tube, and increases the production efficiency by more than 40%.

[0032] 2. The automatic and rapid flipping process of the towel rack tube ends uses sensors to determine the position of the towel rack tubes. Under the control of the electronic system, the cylinder and the feeding slot plate can move the towel rack tubes accurately and quickly. This allows workers to only need to complete auxiliary tasks such as feeding and transferring materials, thereby reducing the workload of workers and enabling workers to operate 2-3 machines at the same time, saving more than 60% of labor costs.

[0033] 3. The automatic and rapid punching process of the towel rack tube end can realize the automatic feeding, forming and feeding operation of the towel rack tube by pushing the oil rod and the forming cylinder of the punch through the mold core. This avoids the need for workers to manually feed the towel rack tube, which not only greatly reduces the labor intensity of workers, but also realizes automated production, thereby reducing labor costs and improving production efficiency.

[0034] 4. The automatic and rapid flipping process of the towel rack tube ends utilizes the compression of the support spring and the downward movement of the component fixed to the top of the support spring. This allows the tube at the top of the rotating wheel to move downward with the wheel, thereby shortening the distance between itself and the towel rack tube previously placed at the bottom. This prevents excessive force from being generated when the upper and lower towel rack tubes come into contact, which could lead to deformation and affect the overall shape quality of the towel rack tubes and subsequent drilling work.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1

[0051] refer to Figures 1 to 6The processing technology for automatic and rapid flushing of the ends of a towel rack tube according to a preferred embodiment of the present invention will be described in detail below:

[0052] The automatic and rapid flushing and turning equipment for towel rack tube ends includes a frame platform 3, a receiving mechanism 4, a receiving bracket 113 fixedly connected to the top of the receiving mechanism 4, towel rack tubes 5, and an electrical control system 6. The processing technology for the automatic and rapid flushing and turning of towel rack tube ends includes the following steps:

[0053] Power control: The electrical control system 6 powers on the feeding mechanism and the punching and forming mechanism, and can be operated by the staff to control the feeding mechanism and the punching and forming mechanism.

[0054] Feeding: Feeding mechanisms are provided on both sides of the frame platform 3. The feeding mechanisms simultaneously store and transport the towel rack tube 5 on both sides, placing the towel rack tube 5 between the two punching and forming mechanisms located on both sides of the frame platform 3.

[0055] Forming: The two punching and forming mechanisms are dynamically adjusted according to the length of the towel rack tube 5. At the same time, the punching and forming mechanisms perform punching, flanging, and height shaping on one end of the towel rack tube 5.

[0056] Feeding: The feeding mechanism delivers the finished towel rack into the collection end through pipe 5.

[0057] The feeding mechanism includes a storage trough plate 11 fixedly connected to the top of the frame platform 3. The storage trough plate 11 has at least three slots, and a support plate 12 is fixedly connected to the bottom of each slot. A pusher cylinder 13 is fixedly connected to the side of the frame platform 3 away from the receiving mechanism 4. A pusher plate 14 is fixedly connected to the output end of the pusher cylinder 13 near the frame platform 3. The height of the pusher plate 14 is higher than that of the support plate 12, so that when the support plate 12 comes into contact with the towel rack tube 5, the support plate 12 can drive the towel rack tube 5 to move into the first contour groove 51, thereby completing the initial feeding step.

[0058] A material support cylinder 15 is fixedly connected to the bottom of the material support plate 12, and a fixing plate 16 is fixedly connected to the bottom of the material support cylinder 15. The fixing plate 16 is fixedly connected to one side of the frame platform 3, and a platform plate 17 is fixedly connected to the bottom of the material storage trough plate 11.

[0059] A positioning slot plate 19 is fixedly connected to one side of the frame platform 3. The top of the positioning slot plate 19 has no less than three contouring slots. The contouring slots are divided into a first contouring slot 51, a second contouring slot 52 and a third contouring slot 53 from the side closest to the pusher cylinder 13 to the side furthest from the pusher cylinder 13. A feeding slot plate 110 is slidably connected to the side of the positioning slot plate 19. An ejector cylinder 114 is fixedly connected to the side of the feeding slot plate 110 furthest from the positioning slot plate 19. A feeding servo device 18 is fixedly connected to the side of the feeding slot plate 110 closest to the pusher cylinder 13.

[0060] The steps for feeding the towel rack tube 5 are as follows:

[0061] A1: The towel rack tube 5 enters from the storage trough plate 11 to the top of the support plate 12. The electrical control system 6 receives the electrical signal emitted by the sensor through the built-in signal receiver.

[0062] A2: The pusher cylinder 13 is started by the control system 6, which pushes the pusher plate 14 to move towards the towel rack tube 5, and then contacts the towel rack tube 5 and drives the towel rack tube 5 into the first contour groove 51.

[0063] A3: At the same time, the feeding card slot plate 110 is started, which drives the towel rack tube 5 located in the first contouring groove 51 of the positioning slot plate 19 into the second contouring groove 52.

[0064] The bottoms of the first contour groove 51, the second contour groove 52, and the third contour groove 53 are all fixedly connected with sensing devices.

[0065] A receiving guide plate 112 is rotatably connected to the side of the positioning groove plate 19 away from the storage groove plate 11;

[0066] The feeding process for the towel rack tube 5 includes the following steps:

[0067] C1: The feeding slot plate 110 moves under the control of the electronic control system 6, and moves the towel rack that is located in the second contour slot 52 and processed to the top of the third contour slot 53 by the tube 5.

[0068] C2: The towel rack tube 5 located at the top of the third contour groove 53 moves down along the receiving guide plate 112 to the top of the receiving mechanism 4 and is collected by the receiving bracket 113.

[0069] The following is the complete working process and working principle of the above embodiments:

[0070] Initial state: such as Figure 1As shown, it consists of a punching and forming mechanism at both ends, a storage and feeding mechanism, a frame platform 3, a receiving mechanism 4, an electrical control system 6, and a hydraulic power system. The punching and forming mechanism on the side closer to the electrical control system 6 is the fixed end, and the punching and forming mechanism on the side farther away from the electrical control system 6 is the adjustable end. The adjustable end can slide and adjust along the track to fix itself according to the length of the workpiece.

[0071] like Figure 6 As shown, the storage and feeding mechanism consists of modules such as a storage trough plate 11, a support plate 12, a pusher cylinder 13, a pusher plate 14, a support cylinder 15, a fixing plate 16, a platform plate 17, a feeding servo device 18, a positioning trough plate 19, a feeding card slot plate 110, and an ejection cylinder 114. The storage trough plate 11 has multiple slots for towel rack tubes 5, and the positioning trough plate 19 has multiple contouring slots, namely a first contouring slot 51, a second contouring slot 52, and a third contouring slot 53. Each of the first contouring slot 51, the second contouring slot 52, and the third contouring slot 53 has a sensor at its bottom.

[0072] The above-mentioned module is set in two sets, which are fixed on the top of the mold base fixing platform 27 included in the punching and forming mechanism and placed on the rails on both sides of the frame platform 3. The two punching and forming mechanisms on both sides form a whole, and the distance between the two punching and forming mechanisms can be adjusted according to the length of the towel rack tube 5. The storage tank plate 11 has three slots, and each slot has a material support plate 12 at the bottom. The material support plate 12 has a pusher plate 14 at the bottom. The pusher plate 14 is set on one side of the storage tank. The operator puts the two ends of the towel rack tube 5 into the three slots of the storage tank plate 11 respectively. The bottom of the storage tank is fixedly connected to the platform plate 17.

[0073] Towel rack tubes 5 of the same length are placed into the storage tank in sequence. At this time, the material support cylinder 15 is in the ejection state, lifting both ends of the towel rack tubes 5 upward. After the equipment is started, the two material support cylinders 15 in one of the slots return to their original positions at the same time, moving the lifted towel rack tubes 5 down onto the platform plate 17. The material pusher cylinder 13 simultaneously drives the material pusher plate 14 to move towards the second contour groove 52. The material pusher plate 14 moves the towel rack tubes 5 parallel to the first contour groove 51 on the positioning groove plate 19. At the same time, the material support cylinder 15 lifts the material support plate 12 upward, so that the material pusher cylinder 13 can drive the material pusher plate 14 to return to its original position.

[0074] The ejector cylinder 114 simultaneously ejects the towel rack tube 5 inside the feeding slot plate 110, lifting it upwards to a position above the positioning slot plate 19. At the same time, the feeding servo device 18 drives the feeding slot plate 110 to move to the next second contouring slot 52 on the positioning slot plate 19. When the towel rack tube 5 is moved above the next contouring slot, the ejector cylinder 114 drives the feeding slot plate 110 to retract downwards. Both ends of the towel rack tube 5 are placed in the contouring slot of the positioning slot plate 19, and the top of the feeding slot plate 110 is lower than the towel rack tube 5. The feeding servo device 18 drives the feeding slot plate 110 to retreat to the starting position, realizing the feeding process of the towel rack tube 5 from the contouring slot of the positioning slot plate 19 to the third contouring slot 53.

[0075] After the punching and forming mechanism punches holes at both ends of the towel rack tube 5, the ejector cylinder 114 pushes the feeding slot plate 110 upward to lift the processed towel rack tube 5 above the positioning slot plate 19. The feeding servo device 18 drives the feeding slot plate 110 to lift the towel rack tube 5 forward to the third contouring slot 53. When the towel rack tube 5 is delivered to the third contouring slot 53, a bevel is provided at one end of the third contouring slot 53. After the feeding slot plate 110 retracts, the towel rack tube 5 falls into the receiving bracket 113 along the slope of both ends of the receiving guide plate 112, realizing automatic receiving.

[0076] Example 2

[0077] refer to Figures 1 to 6 The top of the frame platform 3 is fixedly connected to the mold base fixing platform 27, which is included in the punching and forming mechanism. The top of the mold base fixing platform 27 is fixedly connected to the mold core pushing cylinder 21. The output end of the mold core pushing cylinder 21 near the electrical control system 6 is fixedly connected to the mold core fixing seat 22. The top of the mold core fixing seat 22 is fixedly connected to the punch forming cylinder 24. The side of the mold core fixing seat 22 away from the mold core pushing cylinder 21 is fixedly connected to the core mold 23. The top inner side of the mold core fixing seat 22 is slidably connected to the upper module 25. The bottom inner side of the mold core fixing seat 22 is fixedly connected to the mold pre-assembly block 26. The mold pre-assembly block 26 is located directly below the upper module 25.

[0078] The forming of the towel rack tube 5 includes the following steps:

[0079] B1: The upper module 25 moves downward under the control of the electronic control system 6, and together with the pre-installed module 26, clamps the towel rack tube 5 located in the second contour groove 52;

[0080] B2: The mold core pushes the hydraulic cylinder 21 to start and drive the mold core 23 to insert into the towel rack tube 5, and cooperates with the module 25 to perform the punching and forming work on the towel rack tube 5.

[0081] The following is the complete working process and working principle of the above embodiments:

[0082] When the towel rack tube 5 is delivered to the top of the mold pre-assembly block 26, both ends of the towel rack tube 5 are placed on the lower mold pre-assembly block 26. The mold core push cylinder 21 simultaneously drives the mold core fixing seat 22 to move in opposite directions, extending the mold core 23 into both ends of the towel rack tube 5. The spring-loaded device at one end of the punching and forming mechanism at the adjusting end presses the towel rack tube 5 against the reference limit block at the other end of the punching and forming mechanism, so that the mold core 23 is completely placed in the correct processing position at both ends of the towel rack tube 5.

[0083] The forming cylinder 24 drives the upper module 25 to press downwards, and the ends of the towel rack tube 5 are formed by the die core 23. The forming cylinder 24 drives the upper module 25 to release, and the two die cores push the cylinder 21 to remove the die core 23 from the tubes at both ends. The lower die pre-mounted block 26 uses a spring to push the towel rack tube 5 out of the lower die groove and place it into the original position of the contour groove of the feeding slot plate 110.

[0084] Example 3

[0085] refer to Figures 7 to 10 Each of the two storage trough plates 11 has a partition strip 111 fixedly connected to one side of each other. Each partition strip 111 has a rectangular groove inside. A support spring 1120 is fixedly connected to the bottom of the inner side of each rectangular groove. A rotating plate 1111 is fixedly connected to one end of the top of the support spring 1120. A displacement shaft is rotatably connected inside the rotating plate 1111. The displacement shaft is rotatably connected to the partition strip 111 and also slidably connected to the partition strip 111. A rotating wheel 1112 is rotatably connected to the side of the rotating plate 1111 away from the inner wall of the rectangular groove. A return elastic rope 1113 is fixedly connected between the rotating plate 1111 and the rotating wheel 1112. Transmission gears are rotatably connected to both sides of the bottom of the rotating plate 1111. Wheel 1114, transmission gear 1114 is meshed with rotating plate 1111 on the side near wheel 1112, and displacement gear 1115 is meshed with on the side of transmission gear 1114 away from wheel 1112. A first spring 1118 and a second spring 1119 are fixedly connected to the top of displacement gear 1115. The ends of the first spring 1118 and the second spring 1119 away from displacement gear 1115 are both fixedly connected to the bottom of rotating plate 1111. A force transmission spring 1116 is fixedly connected to the side of displacement gear 1115 near wheel 1112, and a contact plate 1117 is fixedly connected to the end of force transmission spring 1116 away from displacement gear 1115.

[0086] The following is the complete working process and working principle of the above embodiments:

[0087] When the worker releases the towel rack tube 5 downwards between two adjacent partitions 111, the towel rack tube 5 first contacts the rotating wheel 1112 located at the upper end of the storage trough plate 11, and the towel rack tube 5 stops at the top of the rotating wheel 1112 under the support of the two rotating wheels 1112. At the same time, the support spring 1120 is additionally subjected to the gravity of the towel rack tube 5, causing the support spring 1120 to contract downwards. The components fixedly connected to the top end of the support spring 1120 will also contract downwards along with the support spring 1120. As the components contract and move downwards, the contact plate 1117 contacts the bottom towel rack tube 5 when the components descend to a certain distance. Since the cross-sectional shape of the towel rack tube 5 is elliptical, the contact plate 1117 contacts the side of the towel rack tube 5 with a downward curvature. Driven downwards by the displacement tooth block 1115, the contact plate 1117 moves along the curvature of the towel rack tube 5 towards the displacement tooth block 1115. Simultaneously, the contact plate 1117 contacts the towel rack tube 5... The contact generates an upward reaction force, which is applied to the displacement tooth block 1115 through the force transmission spring 1116, causing the displacement tooth block 1115 to move upward. Since the first spring 1118 is in an extended state and the second spring 1119 is in a compressed state, and the first spring 1118 and the second spring 1119 are dynamically balanced, when the displacement tooth block 1115 experiences an additional upward force, its own balance is broken, causing it to move upward. This upward movement is then transmitted through the transmission gear 1114. The transmission causes the rotating plate 1111, which is meshed with the transmission gear 1114, to rotate clockwise around the axis as the displacement tooth block 1115 moves upward. During this process, the distance between the rotating plate 1111 and the transmission gear 1114 reaches its minimum value. At the same time, the rotating wheel 1112 rotates towards the spacer 111, which reduces the contact area between the top of the rotating wheel 1112 and the towel rack tube 5. As a result, the rotating wheels 1112 located on both sides of the towel rack tube 5 no longer contact the towel rack tube 5 and fall downward.

[0088] Since the entire process begins with the contact plate 1117 at the bottom of the towel rack tube 5 contacting the bottom of the towel rack tube 5, the distance between the towel rack tube 5 at the top of the rotating wheel 1112 and the towel rack tube 5 placed forward at the bottom is small. Therefore, according to the gravity formula, the force generated when the towel rack tube 5 at the top of the rotating wheel 1112 falls downward and contacts the towel rack tube 5 placed at the bottom is also small. This avoids the excessive force generated when the two towel rack tubes 5 come into contact, which would cause the towel rack tube 5 to deform under stress and affect the subsequent drilling work on the deformed towel rack tube 5. After the towel rack tube 5 falls from the top of the rotating wheel 1112, the rotating wheel 1112 returns to its initial position under the action of the return elastic rope 1113, and also returns to its initial position under the action of the first spring 1118 and the second spring 1119.
