Description

Technical Field

[0001] This utility model relates to the technical field of audio component processing equipment, and in particular to a heat-setting mechanism for a spring. Background Technology

[0002] As a key vibration support component in a loudspeaker system, the quality of the spider's shaping directly affects the sound quality. In the spider's production process, heat setting is the core step that determines its dimensional accuracy and rebound performance. Currently, traditional spider heat setting equipment mostly uses cylinders or rigid linkage mechanisms to directly drive the mold for mold closing and pressing.

[0003] However, this traditional rigid pressing method is extremely sensitive to machining accuracy and assembly errors. During continuous production, even slight deviations in the mechanical dead spot position or minor fluctuations in material thickness cannot be adaptively adjusted by the rigidly connected mold. This often results in excessive pressure applied to the spring, crushing the material, or insufficient pressure leading to incomplete shaping, severely impacting product consistency and yield. Furthermore, existing heat-setting molds are typically bolted to the pressure plate. When carbon buildup on the mold surface requires cleaning or replacement with different mold sizes, operators must use wrenches and other tools for tedious disassembly, leading to excessive downtime. This not only increases labor intensity but also hinders the overall operational efficiency of the production line.

[0004] Therefore, this utility model proposes a heat-setting mechanism for elastic waves to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a heat setting mechanism for a spring wave, which aims to improve the existing technology of spring wave heat setting equipment. The rigid connection of the pressing mechanism leads to difficulties in pressure adjustment and easy damage to materials, as well as the cumbersome mold fixing method and low efficiency in cleaning, maintenance and replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heat setting mechanism for a spring wave, comprising a heat setting machine, a bracket fixedly connected to the side wall of the heat setting machine, a motor installed on the side wall of the bracket, and a lower template fixedly connected to the bottom of the processing station of the heat setting machine; as well as a lower pressing component, a pressure plate, an upper template, and a disassembly component; The pressing assembly has a structure that converts rotary drive into flexible linear pressing action, and includes a fixed plate, a rotating disk, a fixed shaft, a crank, a guide rail, a slider, a support plate, a slide rod, and a first spring. Furthermore, the fixed plate, the rotating disk, and the motor are combined through rotational engagement and drive connection; the crank and the slider are connected by hinge; the support plate is fixedly connected to the side wall of the slider; the slide rod slides through the guide hole in the support plate and its bottom end is fixedly connected to the pressure plate; the first spring is sleeved on the outer wall of the slide rod located between the support plate and the pressure plate; by the support plate pressing down to compress the first spring, a flexible buffer connection is achieved between the pressing component, the pressure plate, and the upper template. Preferably, the disassembly assembly has a structure that enables quick locking and unlocking, including a protrusion, a rod, a second spring, a limiting rod, and a groove formed on the outer wall of the pressure plate. The rod slides through the side wall of the pressure plate, and the protrusion is fixedly connected to the outer end of the rod. Preferably, the pressure plate further includes a groove formed at its bottom, and the upper template further includes a connecting plate fixed to its top. The connecting plate is slidably disposed in the inner cavity of the groove to guide the installation of the upper template. Preferably, the connecting plate has a locking hole on its side wall, and the inner end of the insertion rod is inserted into the locking hole in the locked state. The second spring is sleeved on the outer wall of the insertion rod located inside the pressure plate to provide an elastic restoring force to reset the insertion rod. Preferably, the connection between the protrusion and the limiting rod is an integral molding connection or a fixed connection, and the limiting rod is slidably fitted in the groove; the protrusion is configured to rotate to a preset angle so that the limiting rod abuts against the outer wall surface of the pressure plate to maintain the unlocked state; Preferably, the crank and the rotating disk are connected by a rotating connection through the eccentrically set fixed shaft, thereby converting the circular motion into the linear reciprocating motion of the slider along the guide rail; Preferably, the top end of the slide bar is provided with a limiting structure to prevent it from dislodging from the guide hole, which is used to drive the pressure plate to reset synchronously when the support plate rises.

[0007] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that rigid transmission is prone to uneven pressure distribution or damage to the elastic material due to mechanical dead point error. It adopts a flexible connection structure between the support plate and the pressure plate, with a sliding rod guide and a first spring buffer. The crank-slider mechanism converts the rotational motion into linear reciprocating motion, and the elastic restoring force of the spring is used for pressing. This achieves the technical effect of eliminating rigid impact, ensuring uniform and stable heat setting pressure, and improving product yield.

[0008] 2. This utility model solves the problem that in the prior art, mold replacement and maintenance require tools, and the disassembly and assembly are cumbersome and time-consuming. It achieves the technical effect of quickly completing mold disassembly and assembly without auxiliary tools, and maintaining the unlocked state with one person and one hand, thus significantly improving the efficiency of equipment maintenance.

[0009] 3. This utility model solves the problem of low production efficiency of manual loading and unloading or single-action equipment in the prior art by using a motor-driven rotating disk and eccentric fixed shaft transmission method, combined with the workstation layout of an automated turntable conveyor system. It achieves the technical effect of realizing continuous and automated production of the spring wave heat setting process and greatly improving production capacity. Attached Figure Description

[0012] 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.

[0013] Reference Figures 1-5The present invention provides an embodiment of a heat-setting mechanism for a bouncy material, comprising a heat-setting machine 1, a bracket 2 fixedly connected to the side wall of the heat-setting machine 1, a pressing component 3 mounted on the bracket 2, a pressure plate 4 connected to the bottom of the pressing component 3, an upper template 5 detachably mounted below the pressure plate 4, a disassembly component 6 integrated inside the pressure plate 4, and a lower template 7 fixedly connected to the bottom of the processing station of the heat-setting machine 1. The heat-setting machine 1 is used to provide overall support and an automated control platform. The lower template 7 has a positioning reference surface for bearing and accurately positioning the bouncy material to be processed. A motor 8 is also fixedly connected to the side wall of the bracket 2, and the motor 8 serves as a power source to drive the pressing component 3 to operate. The pressing assembly 3 serves as a transmission and buffer mechanism, specifically including a fixed plate 301, a rotating disk 302, a fixed shaft 303, a crank 304, a guide rail 305, a slider 306, a support plate 307, a sliding rod 308, and a first spring 309. The fixed plate 301 is fixedly connected to the side wall of the bracket 2, and the rotating disk 302 is rotatably connected to the side wall of the fixed plate 301. The output end of the motor 8 passes through the fixed plate 301 and is fixedly connected to the rotating disk 302, driving its rotation. The fixed shaft 303 is eccentrically positioned on the side wall of the rotating disk 302 and fixedly connected to it. The top end of the crank 304 is sleeved on the outer wall of the fixed shaft 303 and rotatably connected to it. The bottom end of the crank 304 is hinged to the slider 306 via a pin structure. The guide rail 305 is vertically fixedly connected to the inner side of the bracket 2. The slider 306 is slidably embedded in the guide groove of the guide rail 305. The crank 304 converts the eccentric circular motion of the fixed shaft 303 into the reciprocating linear motion of the slider 306 along the length of the guide rail 305. The support plate 307 is fixedly connected to the side wall of the slider 306 and moves synchronously with it. The support plate 307 has a guide hole through it in the vertical direction. The slide rod 308 slides through the guide hole. The bottom end of the slide rod 308 is fixedly connected to the upper surface of the pressure plate 4. The first spring 309 is sleeved on the outer wall of the slide rod 308 located below the support plate 307. The two ends of the first spring 309 abut against the lower surface of the support plate 307 and the upper surface of the pressure plate 4, respectively. The elastic deformation of the first spring 309 realizes flexible transmission and pressure buffering. The pressure plate 4 is used to connect and transmit pressure to the upper template 5. The bottom of the pressure plate 4 has a groove 604 in the horizontal direction. The top of the upper template 5 is fixedly connected to a connecting plate 605 that matches the groove 604. The connecting plate 605 is slidably fitted inside the groove 604. The groove 604 and the connecting plate 605 cooperate to realize the quick guidance, installation and disassembly of the upper template 5. The disassembly component 6 is installed inside the pressure plate 4 and is used to lock the connecting plate 605 after it slides into place to ensure the stability of the mold connection during operation. The crank 304 in the pressing assembly 3 is configured as a power transmission connecting rod. The top end of the crank 304 is rotatably connected to the outer circumferential surface of the fixed shaft 303 via a bearing. The bottom end of the crank 304 is rotatably connected to the top of the slider 306 via a pin. The two side walls of the slider 306 form a sliding fit with the inner wall of the groove of the guide rail 305. The guide rail 305 extends in the vertical direction to strictly limit the movement trajectory of the slider 306. When the crank 304 is subjected to force, the rotational motion of the rotating disk 302 is converted into the vertical reciprocating motion of the slider 306 along the length direction of the guide rail 305. The support plate 307 is fixedly connected to the side surface of the slider 306 as an intermediate transmission component and moves up and down synchronously with it. A precision guide hole is machined through the plate body of the support plate 307 in the vertical direction. The inner wall of the guide hole is ground to reduce frictional resistance. The slide rod 308 serves as a guide connecting the support plate 307 and the pressure plate 4. Its surface forms a clearance fit or transition fit with the inner wall of the guide hole. The top of the slide rod 308 is machined with a limiting structure with an outer diameter larger than the diameter of the guide hole to prevent the slide rod 308 from coming out of the guide hole due to gravity in the early stage of the downward movement of the support plate 307. The bottom end of the slide rod 308 is vertically fixedly connected to the upper surface of the pressure plate 4. Meanwhile, the first spring 309 is coaxially sleeved on the outside of the slide rod 308 located between the support plate 307 and the pressure plate 4. The upper end face of the first spring 309 abuts against the lower surface of the support plate 307, and the lower end face of the first spring 309 abuts against the upper surface of the pressure plate 4. In the assembled state, the first spring 309 is restricted between the support plate 307 and the pressure plate 4. This elastic floating connection method, guided by the slide rod 308 and transmitted by the first spring 309, ensures that when the pressure plate 4 drives the upper template 5 to move downward and stops when it comes into contact with the workpiece, the support plate 307 can still continue to move downward under the drive of the drive motor 8 and compress the first spring 309. The elastic restoring force generated by the deformation of the first spring 309 is used to apply a continuous and gentle holding pressure to the material, which effectively avoids the hard collision damage caused by mechanical dead point errors in traditional rigid connections and ensures that the product is pressed evenly. As a preferred embodiment, to solve the problem of numerous disassembly and assembly tools and time-consuming and laborious process when changing existing molds, a special quick-release connection structure is adopted between the pressure plate 4 and the upper template 5. The lower surface of the pressure plate 4 has a through or semi-through groove 604 in the horizontal direction. The cross-sectional shape of the groove 604 is designed as a dovetail shape, T-shape, or inverted trapezoid. The connecting plate 605 serves as a protruding structure on the top of the upper template 5. Its cross-sectional shape forms a sliding clearance fit with the inner cavity shape of the groove 604. The side wall of the connecting plate 605 is machined with deep holes or through holes as locking holes. The horizontal sliding fit between the groove 604 and the connecting plate 605 allows the upper template 5 to be quickly inserted or pulled out from the side. As a further preferred embodiment, in order to reliably lock the upper template 5 without the aid of external tools, the disassembly assembly 6 is integrated and installed inside the pressure plate 4. The side wall of the pressure plate 4 has a horizontal mounting hole that communicates with the inside of the groove 604. The insertion rod 602 slides through the mounting hole. The inner end of the insertion rod 602 is machined into a shape that can be smoothly inserted into the locking hole on the side wall of the connecting plate 605. The end of the insertion rod 602 located outside the pressure plate 4 is fixedly connected to the protrusion 601. The protrusion 601 serves as a manual operating component to facilitate the worker's gripping or application of force. The second spring 603 is coaxially sleeved on the section of the rod 602 located in the cavity inside the pressure plate 4. One end of the second spring 603 abuts against the shoulder or flange on the rod 602, and the other end abuts against the inner wall of the pressure plate 4. The second spring 603 is in a pre-compressed state, and its released elastic restoring force always drives the rod 602 to move into the interior of the pressure plate 4, thereby maintaining the locked state of the rod 602 inserted into the locking hole. In another preferred embodiment, to facilitate the operator to disassemble the mold with one hand and maintain the unlocked state, a groove 607 parallel to the axial direction of the insertion rod 602 is provided on the outer wall of the pressure plate 4. The limiting rod 606 is fixedly connected to the side of the protrusion 601 facing the pressure plate 4. The limiting rod 606 is designed to slide within the groove 607. When unlocking is required, the protrusion 601 is pulled outward to move the limiting rod 606 outward along the groove 607 until the limiting rod 606 is completely out of the constraint range of the groove 607. Then, the protrusion 601 is rotated to a preset angle so that the limiting rod 606 is offset from the groove 607 and abuts against the outer wall surface of the pressure plate 4. The blocking effect of the outer wall of the pressure plate 4 on the limiting rod 606 overcomes the rebound force of the second spring 603, thereby keeping the insertion rod 602 in the unlocked position away from the locking hole.

[0014] Working principle: When using this equipment for production operations, the bouncy material to be processed is first accurately transferred to the processing station of the heat setting machine 1 through an external automated turntable conveyor system and placed on the positioning reference surface of the lower template 7 to ensure that the material position is accurate. Subsequently, the drive motor 8 on the side wall of the bracket 2 is started. The output end of the motor 8 drives the rotating disk 302 on the fixed plate 301 to start rotating, which in turn drives the fixed shaft 303, which is eccentrically fixed on the side wall of the rotating disk 302, to rotate synchronously. The fixed shaft 303 drives the crank 304 sleeved on it to perform eccentric circular motion through connection. Since the bottom of the crank 304 is hinged to the slider 306, and the slider 306 is restricted in the guide groove of the guide rail 305, the circular motion of the crank 304 is converted into the up-and-down reciprocating sliding of the slider 306 along the length direction of the guide rail 305. When the slider 306 moves downward, it drives the support plate 307, which is fixed to the side wall, to move downward synchronously. The support plate 307 transmits pressure to the pressure plate 4 below through the first spring 309, which in turn drives the upper template 5 installed at the bottom of the pressure plate 4 to move closer to the lower template 7. When the upper template 5 contacts the material and stops due to obstruction, the support plate 307 continues to move downward for a certain distance, compressing the first spring 309. At this time, the first spring 309 undergoes elastic deformation, using its elastic restoring force to apply flexible and continuous pressure to the upper template 5, which not only buffers the rigid impact but also ensures the uniform and stable shaping pressure, thus completing the heat setting process. When the upper template 5 needs to be cleaned, repaired, or replaced during production, the operator pulls the protrusion 601 outward, causing the insertion rod 602 to slide outward along the through hole of the pressure plate 4, overcoming the resistance of the second spring 603. During this process, the inner end of the insertion rod 602 completely disengages from the locking hole on the connecting plate 605, and at the same time, the limiting rod 606 on the side wall of the protrusion 601 completely disengages from the slide groove 607. After the limiting rod 606 is released from its constraint, the protrusion 601 is rotated to a preset angle, causing the limiting rod 606 to abut against the outer wall surface of the pressure plate 4. The outer wall of the pressure plate 4 prevents the limiting rod 606 from retracting, thereby keeping the insertion rod 602 in the unlocked state. Subsequently, the operator pulls the upper template 5 horizontally, allowing the connecting plate 605 to smoothly slide out from the groove 604 at the bottom of the pressure plate 4, thus quickly completing the mold disassembly operation.
