Description

Technical Field

[0001] This application belongs to the field of heat shrink tubing processing and manufacturing technology, specifically relating to a heat shrink tubing stamping device. Background Technology

[0002] In the current heat shrink tubing manufacturing field, the stamping process for heat shrink tubing has significant limitations. Previously, incoming heat shrink tubing was typically in 1.2-meter lengths. Before stamping, it had to be manually cut to the required length using a cutting machine. After cutting, each cut section of heat shrink tubing still needed to be precisely placed into a stamping die for stamping.

[0003] In this traditional processing method, the cutting and stamping stages are highly dependent on manual operation, resulting in low production efficiency, making it difficult to meet the needs of large-scale production, and posing numerous safety hazards. During long-term, high-frequency cutting and handling, operators' hands are frequently near the cutting machine blades and stamping dies, making them extremely prone to cuts, crush injuries, and other accidents, posing a significant risk. Furthermore, prolonged repetitive physical labor can cause severe fatigue for operators. As working hours increase, operational precision and concentration gradually decline, affecting product quality and production efficiency, increasing the defect rate, and also raising the probability of workplace accidents.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0033] Example 1:

[0034] Please see the appendix Figure 1-3 , Figure 1 In Figure 1A, the heat shrink tubing is in an un-stamped state, and in Figure 1B, it is in a stamped state.

[0035] This application discloses a heat shrink tubing stamping apparatus, including a stamping machine 11, a feeding mechanism 2, a cutting mechanism 3, and a conveying mechanism. The stamping machine 11 performs heat shrink tubing stamping; the feeding mechanism 2, located on one side of the stamping machine 11, is responsible for material input; the cutting mechanism 3, located on the other side of the stamping machine 11, is responsible for finished product cutting; the conveying mechanism includes a drive unit 41, a feeding group 42, and a conveying group 43. The drive unit 41 synchronously controls the two conveying groups, the feeding group 42 connects the feeding mechanism 2 and the stamping machine 11, and the conveying group 43 connects the cutting mechanism 3 and the stamping machine 11.

[0036] The stamping mechanism 11 refers to the functional module that performs the stamping action. Specifically, it can be implemented using a hydraulic press in conjunction with a die set, completing the punching or forming of heat shrink tubing through the closing of the upper and lower dies. The feeding mechanism 2 refers to the material conveying device, which can be implemented using a roller conveyor belt or chain conveyor to continuously transport the heat shrink tubing raw material to the processing position. The cutting mechanism 3 refers to the material cutting device, which can be implemented using a rotary cutter 32 or a guillotine cutter to cut the stamped tubing to a fixed length. The feeding mechanism refers to the material transfer control system. The drive component 41 can be a servo motor 31 or a stepper motor 31, which simultaneously drives the feeding group 42 and the feeding group 43 through gear transmission or belt transmission, ensuring that the input of material in the front stage and the output in the back stage remain synchronized.

[0037] Specifically, during operation, the feeding mechanism 2 continuously delivers the heat shrink tubing raw material to the stamping station. The drive unit 41 synchronously controls the feeding group 42 and the conveying group 43, ensuring the raw material is precisely fed into the processing area before stamping, and the semi-finished product after stamping is promptly transferred to the cutting station. After the stamping machine 11 completes the forming process, the conveying group 43 delivers the workpiece to the cutting mechanism 3 for fixed-length cutting. These four mechanisms form a closed-loop processing flow, with materials automatically flowing between them without manual intervention. The layout design of the stamping machine 11 and the cutting mechanism 3, positioned on opposite sides, ensures a straight flow path between raw material input and finished product output, avoiding the risk of jamming caused by material backflow.

[0038] Through the above technical solution, this application integrates the originally separate stamping and cutting processes into a continuous processing unit by synchronously controlling the feeding mechanism. In particular, the linkage control of the drive unit 41 with the feeding group 42 and the feeding group 43 solves the timing matching problem of material transfer in multiple workstations, effectively eliminates the safety hazards caused by manual operation, and avoids the risk of operators coming into contact with the cutting blades 32 and stamping dies. The device achieves seamless connection of the processing flow through automated material transfer, significantly improving production cycle time and processing efficiency. In addition, the integrated design of the stamping and cutting processes reduces the equipment footprint and optimizes the production line layout space.

[0039] Please see the appendix Figure 4 This application further proposes the specific structure of the cutting mechanism 3 in the heat shrink tubing stamping device. The cutting mechanism 3 includes a motor 31, a cutter 32 and a support frame 33. The support frame 33 is slidably connected to the cutter 32, and the motor 31 is drivenly connected to the cutter 32.

[0040] The support frame 33 is a guide component that supports the movement trajectory of the cutter 32. It can be implemented using a metal frame structure with linear guide rails, providing a stable movement path for the cutter 32. The cutter 32 is the actuator used to cut heat shrink tubing, typically a rectangular alloy steel blade, which performs the cutting action through linear reciprocating motion. The motor 31 is the power source that drives the cutter 32. It can be implemented using a servo motor 31 or a stepper motor 31, converting rotary motion into linear motion of the cutter 32 through a transmission mechanism.

[0041] Specifically, after the heat shrink tubing completes the stamping process, the motor 31 receives a control signal and starts operating, transmitting power to the cutter 32 via a coupling or synchronous belt. The cutter 32 reciprocates linearly under the constraint of the linear guide rail of the support frame 33. When the cutter 32 is in its lower stroke, the cutting edge contacts the heat shrink tubing to be cut, completing the cutting operation. The sliding connection structure of the support frame 33 effectively limits the lateral displacement of the cutter 32 during movement, ensuring the cutting surface remains perpendicular. The motor 31 uses an encoder or position sensor to control the stroke, causing the cutter 32 to automatically reset after completing the cutting action at a predetermined position.

[0042] Through the above technical solution, this solution uses a motor 31 to drive the cutter 32 in conjunction with the guide support frame 33 to realize automated continuous cutting operations, eliminating the risk of manual direct contact with the cutter, and improving the continuity and stability of the cutting operation through automated control.

[0043] This application further proposes a stamping machine 11 structure including a stamping machine 11, an upper die 12 and a lower die 13, wherein the stamping machine 11 is connected to the upper die 12 and the upper die 12 and the lower die 13 are arranged opposite to each other.

[0044] The stamping press 11 refers to the power device that provides vertical stamping force, specifically a hydraulic stamping press 11 driven by a servo motor 31, with the stamping depth controlled by setting stroke parameters. The upper die 12 refers to the moving component that performs the stamping action, specifically including a punch 121 and an elastic buffer structure, forming a dynamic cooperation relationship with the lower die 13 during the stamping process. The lower die 13 refers to the fixed support component, specifically including a punch plate 131 with positioning holes and a support bracket 132, with the punch shape and the size of the punch 121 forming a clearance fit.

[0045] Specifically, the power output end of the stamping press 11 is rigidly connected to the upper die 12, driving the punch 121 to reciprocate vertically. When the heat shrink tubing to be processed is automatically conveyed to the punching plate 131 of the lower die 13, the punch 121 descends to penetrate the tubing and resets under the buffering action of the elastic element 123. The punching plate 131 forms a stable support surface with the base plate through the bracket 132, maintaining planar accuracy during continuous stamping operations. Through the clearance fit design between the punch 121 and the punching plate 131, the tubing will not shift or wrinkle when cut.

[0046] In some specific embodiments, the punch 121 may be made of tungsten steel, with a 0.05 mm chamfer at the cutting edge to reduce burrs on the pipe cut. The punch plate 131 may be equipped with a quick-change module, enabling precise positioning of dies with different hole diameters via locating pins. The elastic element 123 may be a nitrogen spring, with its compression stroke set to 10%-15% of the total stroke of the punch 121.

[0047] Through the above technical solution, this solution utilizes automated mechanical feeding combined with a closed stamping structure to ensure that pipe positioning and stamping are completed inside the equipment. This achieves precise alignment during the automatic stamping process of heat shrink tubing and eliminates the safety hazards associated with manual operation. The stamping force is applied directly to the pipe through a vertical transmission path, avoiding material deformation caused by traditional lateral stamping. The split-module design reduces mold maintenance time.

[0048] This application further proposes an improved scheme for the stamping mechanism 11 in the heat shrink tubing stamping device, including the structural design of the upper module 12 and the lower module 13. The upper module 12 includes a punch 121, a force-bearing component 122, an elastic component 123, and a pressure plate 124. The punch 121 is connected to the force-bearing component 122, and the elastic component 123 is connected between the force-bearing component 122 and the pressure plate 124. The pressure plate 124 has a first punch corresponding to the punch 121. The lower module 13 includes a punch plate 131, a bracket 132, and a base plate. The punch plate 131 has a second punch corresponding to the punch 121 and is located at the upper end of the bracket 132. The bracket 132 is located on the base plate.

[0049] The punch 121 is a metal component used to apply punching pressure to form holes in the heat shrink tubing. It can be made of hard alloy material, and its shape matches the required punching shape to ensure precise material penetration during the punching process. The force-bearing component 122 is a rigid structural component used to transmit the punching pressure. It can be made of high-strength steel and is fixedly connected to the punch 121 by bolts to ensure even distribution of the punching pressure. The elastic component 123 is an element with elastic recovery capability, specifically a coil spring or rubber pad. It is installed between the force-bearing component 122 and the pressure plate 124, providing cushioning and automatic reset during the punching process. The pressure plate 124 is a plate-shaped component used to fix the heat shrink tubing. It can be a metal plate with anti-slip texture, and its first punch hole matches the size of the punch 121, ensuring smooth passage of the punch 121 and limiting the material. The perforated plate 131 refers to a support plate with a second perforation corresponding to the punch 121. It can be made of wear-resistant tool steel, and the accuracy of its hole position is ensured by CNC machining. It forms a clearance fit with the punch 121 to achieve precise positioning. The bracket 132 refers to the frame structure used to support the perforated plate 131. It can be a welded steel frame or a cast base. Its bottom is fixed to the base plate with bolts to ensure overall stability during the stamping process.

[0050] Specifically, when the press 11 starts, the upper die 12 moves downward, and the pressure plate 124 first contacts the heat shrink tubing and presses it firmly against the surface of the lower die 13. At this time, the elastic element 123 is compressed to maintain a fixed pressure. As the stamping force continues to increase, the punch 121 passes through the first punch hole of the pressure plate 124 and the second punch hole of the punching plate 131 in sequence, completing the punching operation on the heat shrink tubing. After the stamping is completed, the press 11 drives the upper die 12 to retract, and the elastic element 123 releases the stored elastic potential energy, causing the pressure plate 124 to separate and reset from the force-bearing element 122. At this time, the heat shrink tubing that has completed the stamping is automatically removed by the feeding mechanism. Throughout the process, the precise cooperation between the punch 121 and the punching plate 131 is achieved through mechanical structure positioning, without the need for manual adjustment. The rigid connection between the bracket 132 and the base plate effectively suppresses vibration and displacement.

[0051] Through the above technical solution, this solution achieves automatic fixing and resetting through the synergistic effect of the pressure plate 124 and the elastic element 123. Operators can complete the processing without contacting the stamping area, effectively improving operational safety. The mechanical positioning and automatic resetting functions significantly improve processing efficiency and shorten the single stamping cycle. The precise cooperation between the punch 121 and the punching plate 131 ensures the consistency of the punching position and eliminates defective products caused by manual positioning errors. The rigid support structure of the bracket 132 and the base plate further ensures the stability of the stamping process and avoids the impact of equipment offset on processing accuracy.

[0052] Example 2:

[0053] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 5 This application further proposes that the feeding mechanism 2 includes a guide block 21, and the guide block 21 is provided with a feeding trough 211 corresponding to the feeding group 42.

[0054] Specifically, the guide block 21 forms a mechanical connection with the feeding assembly 42 through a fixed installation position. After the heat shrink tubing is pushed into the inlet end of the feeding groove 211, it is radially constrained by the groove wall and can only move along the length direction of the feeding groove 211. When the heat shrink tubing moves to the end of the feeding groove 211, its front end has been precisely guided to the clamping center line position of the feeding assembly 42. At this time, the drive component 41 of the feeding assembly 42 starts the clamping action to complete the automated feeding. The rigid structure of the guide block 21 can resist external force interference and avoid positioning deviation of the heat shrink tubing due to inertia or vibration during the transportation process. At the same time, the continuous guide surface of the feeding groove 211 eliminates the need for manual correction of the tubing position.

[0055] Through the above technical solution, this application achieves automatic centering and positioning of the pipe before it enters the clamping mechanism by the synergistic effect of the guide block 21 and the feed chute 211. This enables precise positioning to be completed without manual intervention during the feeding process, avoids manual adjustment operations, significantly reduces the risk of operators coming into contact with moving parts, and improves the consistency of the feeding cycle, providing a basic guarantee for continuous automated production.

[0056] This application further proposes a heat shrink tubing stamping device including an optical fiber sensor 22, which is located above the feed trough 211 and connected to the guide block 21. The optical fiber sensor 22 is used to sense whether the feed trough 211 is in a material-containing state or a material-free state.

[0057] Specifically, when the heat shrink tubing enters the feed trough 211, the fiber optic sensor 22 determines the presence of material in the trough by receiving changes in the intensity of the reflected light signal. When no material is detected, the equipment control system can trigger a shutdown or alarm action; when material is detected, the feeding mechanism automatically starts to complete the material conveying. This detection method replaces continuous manual observation of the material's state, enabling the equipment to autonomously determine whether processing conditions are met, thereby eliminating the risk of crushing injuries faced by operators who need to get close to the equipment to observe the material.

[0058] Through the above technical solution, this application converts the material state into a recognizable electrical signal via a photoelectric signal conversion mechanism, enabling the equipment to sense material availability in real time. The detection response time can be shortened to the millisecond level, achieving automated real-time monitoring of the material state. This effectively prevents mold damage caused by material shortages. Operators no longer need to frequently approach the stamping area to check the material state, eliminating the safety hazard of accidental hand entry into the dangerous area.

[0059] This application further proposes that the feeding mechanism 2 also includes a limiting component 23, which is located between the stamping machine 11 and the feeding group 42.

[0060] The material limiting component 23 includes a first cylinder 231 and a limiting plate 232, with the first cylinder 231 and the limiting plate 232 being drivenly connected.

[0061] Specifically, before the feeding group 42 conveys the heat shrink tubing to the stamping machine 11, the limiting plate 232 intercepts it between the feeding group 42 and the stamping machine 11, thereby blocking the entry of the heat shrink tubing. This can effectively prevent the heat shrink tubing from entering in excess or prematurely, thus affecting the stamping quality.

[0062] When the fiber optic sensor 22 detects that the material has reached the set position, it sends a signal to the control system. At this time, the first cylinder 231 receives the action command and drives the limiting plate 232 to rise vertically to the set height, moving the limiting plate 232 away from the position between the feeding group 42 and the stamping machine 11, so that the heat shrink tubing can enter the stamping machine 11 from the feeding mechanism 2. After a section of heat shrink tubing is stamped, the first cylinder 231 drives the limiting plate 232 to descend to the initial position, blocking the material channel. This process forms periodic limit control through the reciprocating motion of the cylinder, so that the length error of the heat shrink tubing entering the stamping area each time is controlled within ±0.5 mm.

[0063] Through the above technical solution, this application effectively solves the problem of mold jamming caused by excessive material feeding during the stamping process, and eliminates stamping position deviation caused by material placement misalignment during manual operation. The precise lifting and lowering action of the limiting plate 232 driven by the cylinder ensures that the heat shrink tubing is always in the predetermined position before stamping, ensuring that the perpendicularity error between the punch and the tube body axis is less than 1 degree. This mechanical limiting method can achieve continuous stamping operations of 30-50 times per minute, which is about 3 times more efficient than traditional manual operation, and avoids the safety hazard of the operator's hands entering the dangerous area.

[0064] Example 3:

[0065] This embodiment is based on the above embodiment; please refer to [link / reference]. Figure 6 This application further proposes that the feeding mechanism also includes a second cylinder 44; the feeding group 42 includes a first feeding wheel 421 and a second feeding wheel 422 arranged opposite to each other; the second cylinder 44 is driven to the first feeding wheel 421; and the driving component 41 is driven to the second feeding wheel 422.

[0066] The feeding assembly 42 refers to the mechanical component used to clamp and transport heat shrink tubing. Specifically, it can be implemented using a pair of symmetrically arranged metal rollers, which generate friction through active rotation to drive the heat shrink tubing linearly. The opposing feeding rollers refer to a clamping structure with two rollers whose axes are parallel and symmetrically arranged in the vertical direction. Specifically, they can be steel rollers with anti-slip textures on their surface, and the distance between the two rollers can be adjusted to accommodate different tubing diameters. The second cylinder 44 is a linear drive device used to adjust the distance between the first feeding roller 421 and the second feeding roller 422. Specifically, it can be a single-piston rod double-acting pneumatic actuator, with its cylinder body fixed to the frame and the piston rod connected to the upper feeding roller bearing seat. The drive connection refers to the power transmission relationship. Specifically, it can be achieved by rigidly connecting the cylinder piston rod to the feeding roller bearing seat through a coupling, realizing vertical displacement control of the feeding rollers.

[0067] Specifically, the first feed roller 421 and the second feed roller 422, positioned opposite each other, maintain a distance in the initial state. After the heat shrink tubing is guided between the two rollers, the second cylinder 44 pushes the upper feed roller downwards to form a clamping state. When the drive unit 41 rotates the lower feed roller, the clamped heat shrink tubing is continuously conveyed to the stamping station under friction. When a change in processing specifications is required, the second cylinder 44 can lift the upper feed roller to release the clamp, allowing for quick replacement of feed roller sets with different diameters. By setting the cylinder stroke parameters through a programmable controller, the clamping pressure can be precisely controlled, preventing both tubing slippage and excessive compression deformation. This structure achieves automated control of the feeding process, requiring operators to perform loading operations only within a safe area.

[0068] Through the above technical solution, this application realizes the mechanized continuous conveying of materials during the heat shrink tubing stamping process, eliminating the safety hazards of direct manual contact with the stamping die. The adjustable feed roller spacing mechanism allows the same equipment to adapt to various pipe diameter specifications, reducing equipment modification costs. The automated feeding process maintains a stable feed speed and positioning accuracy, avoiding feeding position deviations caused by manual operation and improving the consistency of stamping quality.

[0069] This application further proposes that the feeding mechanism also includes a third cylinder 45, and the feeding group 43 includes a first feeding wheel 431 and a second feeding wheel 432 arranged opposite to each other. The third cylinder 45 is driven to the first feeding wheel 431, and the driving component 41 is driven to the second feeding wheel 432.

[0070] Specifically, the third cylinder 45 pushes the first feeding wheel 431 downwards, forming a clamping space with the second feeding wheel 432, and the stamped heat shrink tubing is clamped between the two feeding wheels. The drive unit 41 drives the second feeding wheel 432 to rotate, causing the heat shrink tubing to move in a predetermined direction. When heat shrink tubing of different thicknesses needs to be processed, the third cylinder 45 adjusts the lifting position of the first feeding wheel 431 according to the thickness parameters, so that the distance between the two feeding wheels matches the thickness of the heat shrink tubing, ensuring uniform clamping force and preventing slippage. The stamped heat shrink tubing is automatically discharged through the continuous rotation of the feeding wheels, without the need for manual intervention.

[0071] Through the above technical solution, this application realizes automated continuous conveying of heat shrink tubing after stamping, eliminating safety hazards in the manual feeding process and solving the problems of low efficiency and difficulty in switching product specifications by manual operation. The dynamic adjustment function of the clamping distance ensures stable conveying of heat shrink tubing of different thicknesses, avoiding material deviation or slippage caused by insufficient clamping force, and enabling the production line to adapt to the needs of multi-variety production.
