Description

Technical Field

[0001] This utility model relates to the field of spring processing equipment technology, and in particular to a spiral spring winding machine. Background Technology

[0002] As a widely used general-purpose basic component, helical springs play an indispensable role in many industries such as machinery, electronics, automobiles, and daily necessities. Their production mainly relies on various types of helical spring winding machines. Traditional helical spring winding machines usually use a set of mechanical structures to realize the feeding, winding, and cutting of metal raw materials.

[0003] During the production process, in order to adapt to the needs of different products, it is necessary to frequently adjust the radius (diameter) and pitch of the spring. In the existing technical solutions, the adjustment mechanisms for these two dimensions are often complex in structure or have mechanical linkages with each other, which makes the adjustment process cumbersome and requires experienced technicians to conduct long-term debugging. This not only results in low production efficiency, but also makes it difficult to guarantee the accuracy and stability of the adjustment, thus affecting the qualification rate of the final product.

[0004] Furthermore, metal shavings are inevitably generated during the cutting process after the spring winding is completed. These shavings usually fall directly to the bottom or around the equipment, easily causing a dirty working environment and increasing the workload of manual cleaning. More seriously, if these metal shavings splash or enter the delicate transmission components inside the equipment, they may cause wear or even damage to the equipment, and also pose certain safety hazards to on-site operators. Existing equipment generally lacks an integrated and efficient automatic shavings recovery system, making it impossible to effectively guarantee the cleanliness and safety of the production process.

[0005] Therefore, this utility model proposes a spiral spring winding machine to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of complex and inaccurate adjustment of spring diameter and pitch in existing helical spring winding machines, as well as untimely and incomplete recovery of metal debris generated during processing, this utility model aims to provide a helical spring winding machine with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a spiral spring winding machine, including: a machine body, a transmission component, a feeding component, a housing, an adjustment component, a mounting plate, a hydraulic rod, a cutter, and a recycling component.

[0022] 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.

[0023] Please refer to Figures 1-5 This utility model provides a spiral spring winding machine, which aims to solve the problems of inconvenient and inaccurate adjustment of spring diameter and pitch and inefficient recycling of metal scrap in the prior art.

[0024] like Figure 1 and Figure 2 As shown, the spiral spring winding machine includes a machine body 1 and a transmission assembly 2 fixedly connected to one side of the machine body 1. The machine body 1 serves as the bearing platform and basic frame of the entire winding machine. Its structure is sturdy and stable, providing support for the installation and operation of all other components. The transmission assembly 2 is provided with a channel for conveying raw materials. The end of this channel is connected to the housing 4, ensuring that the raw materials can smoothly enter the processing area inside the housing 4 from the transmission assembly 2. The transmission assembly 2 specifically includes an upper guide wheel 201 and a lower guide wheel 202. The upper guide wheel 201 and the lower guide wheel 202 are arranged opposite each other in the vertical direction, jointly clamping the raw materials to be processed. Their rotation drives the raw materials to move forward, and straightens them during the material conveying process, eliminating any bending or deformation that may exist in the raw materials before winding, ensuring that the subsequently wound springs have high precision and consistency.

[0025] On the other side of the machine body 1, a feeding assembly 3 is fixedly connected. The feeding assembly 3 is equipped with a structure for guiding raw materials. This structure is connected to the inlet of the transmission assembly 2. The feeding assembly 3 includes a guide frame 302 and a base 303. Two guide shafts 304 are provided inside the guide frame 302. The raw material wire first passes between the two guide shafts 304. The guide shafts 304 perform preliminary positioning and limiting of the raw material to prevent the raw material from deviating from the track or suddenly bending during use. The base 303 is fixedly connected to the bottom of the guide frame 302. A guide wheel set 301 is provided on the top of the base 303. The guide wheel set 301 provides more precise guidance for the raw material passing through the guide shafts 304 to ensure that the raw material can enter the transmission assembly 2 smoothly and accurately.

[0026] The housing 4 is fixedly connected to the top of the machine body 1, forming a relatively enclosed processing space. An adjusting assembly 5 is slidably fitted inside the housing 4. The adjusting assembly 5 is the core mechanism for achieving precise spring winding. The adjusting assembly 5 includes a first electric push rod 501, a second electric push rod 502, and an extrusion roller 503. The first electric push rod 501 is arranged horizontally, and its moving end is fixedly connected to the extrusion roller 503. The radial position of the extrusion roller 503 is precisely controlled by the extension and retraction of the first electric push rod 501, thereby directly determining the radius of the wound spring and achieving fine adjustment of the spring diameter. The second electric push rod 502 is arranged vertically, and its moving end is fixedly connected to the first electric push rod 501. The extension and retraction of the second electric push rod 502 drives the entire first electric push rod 501 and the extrusion roller 503 to move up and down vertically, thereby controlling the winding of the raw material at different heights, and thus determining the distance between the coils of the spring, i.e., the pitch. The housing 4 also has a guide structure inside to support the sliding of the adjusting assembly 5, ensuring the stability and accuracy of the adjusting assembly 5 during movement.

[0027] A mounting plate 7 is fixedly connected to the bottom of the machine body 1. A hydraulic rod 8 is movably connected to the bottom of the mounting plate 7. A cutter 9 is fixedly connected to the moving end of the hydraulic rod 8. The piston rod of the hydraulic rod 8 can drive the cutter 9 to reciprocate in the vertical direction. When the spring has been wound to the set number of turns, the cutter 9 quickly cuts the raw material wire to complete the production of a single spring.

[0028] A recovery assembly 6 is fixedly connected to the bottom of the machine body 1. The recovery assembly 6 is responsible for collecting metal debris generated during the winding and cutting process. The recovery assembly 6 includes a collection box 601, an exhaust fan 603, and a collection trough 604. The exhaust fan 603 is airtightly connected to the collection box 601 through an air pipe 602. When the exhaust fan 603 is working, it creates a negative pressure environment inside the collection box 601. The collection trough 604 is located below the cutter 9 and is used to receive metal debris that falls during the cutting process. The collection trough 604 is airtightly connected to the collection box 601 through a pipe 605. Under the action of negative pressure, the metal debris in the collection trough 604 is sucked into the collection box 601 for centralized processing.

[0029] Please refer to Figure 3 , Figure 4 and Figure 5The adjusting assembly 5 has a structure that enables precise setting of the spring radius and pitch. It includes a first electric push rod 501 arranged horizontally, with a pressing wheel 503 fixedly connected to the moving end of the first electric push rod 501. The adjusting assembly 5 also includes a second electric push rod 502 arranged vertically, with the moving end of the second electric push rod 502 fixedly connected to the first electric push rod 501. In the assembled state, the entire adjusting assembly 5 slides inside the housing 4 and obtains stable support through the guide structure inside the housing 4. This hierarchical connection structure of the two electric push rods ensures that the extension and retraction of the first electric push rod 501 can independently drive the pressing wheel 503 to move radially, thereby precisely controlling the spring radius. At the same time, the extension and retraction of the second electric push rod 502 can drive the entire first electric push rod 501 and pressing wheel 503 to move vertically as a whole, thereby precisely controlling the spring pitch. This achieves independent and convenient adjustment of the two key parameters.

[0030] The recycling component 6 has a structure for efficiently collecting metal scrap, including a collection trough 604 located directly below the cutter 9, which is airtightly connected to the collection box 601 via a pipe 605. The collection box 601 is airtightly connected to the exhaust fan 603 via the air pipe 602. When the exhaust fan 603 is working, it creates a negative pressure suction in the collection box 601 and the collection tank 604 through the air pipe 602 and the pipe 605. This negative pressure recovery structure ensures that all metal debris generated by the cutter 9 when cutting raw materials can be immediately sucked into the collection box 601, avoiding debris splashing and accumulation. To protect the exhaust fan 603, a filter screen 607 is installed inside the collection box 601 and between the air pipe 602 and the exhaust fan 603. The filter screen 607 can effectively intercept the sucked-in metal debris. A sliding door 606 is also provided on one side wall of the collection box 601. The sliding door 606 is connected to a handle 608. By pulling the handle 608 to open the sliding door 606, the debris accumulated inside the box can be easily cleaned.

[0031] In a preferred embodiment, the transmission component 2 includes an upper guide wheel 201 and a lower guide wheel 202. The upper guide wheel 201 and the lower guide wheel 202 are arranged opposite each other in the vertical direction and together clamp the raw material to be processed. This arrangement of dual guide wheels can not only stabilize the transmission direction of the raw material, but also effectively straighten it by applying a certain pressure to the raw material, so as to avoid the bending of the raw material from having an adverse effect on the subsequent winding accuracy.

[0032] In a preferred embodiment, the feeding assembly 3 includes a guide frame 302 and a base 303. The guide frame 302 has two guide shafts 304 inside. The guide shafts 304 can be smooth cylinders, used to initially guide and limit the path of the raw material, preventing the raw material from deviating significantly when entering the equipment. The base 303 is fixedly connected to the bottom of the guide frame 302. The top of the base 303 is provided with a guide wheel set 301, which includes multiple rollers. Their arrangement matches the travel path of the raw material, providing smooth and precise secondary guidance for the raw material, ensuring that the raw material is stably transported to the transmission assembly 2.

[0033] In a preferred embodiment, the extension and retraction of the first electric push rod 501 of the adjusting component 5 drives the extrusion wheel 503 to move radially, thereby achieving stepless adjustment of the spring diameter. The extension and retraction of the second electric push rod 502 drives the first electric push rod 501 and the extrusion wheel 503 to move vertically, thereby achieving stepless adjustment of the spring pitch. This independent and precise electric push rod control method improves the flexibility and accuracy of spring size adjustment and adapts to the production needs of springs of different specifications.

[0034] In a preferred embodiment, a filter 607 is provided inside the collection box 601. The filter 607 is located between the air pipe 602 and the exhaust fan 603. The filter 607 is made of high-strength metal wire mesh or similar material. Its pore size can effectively block metal debris from being sucked into the exhaust fan 603, while ensuring smooth airflow, thereby protecting the exhaust fan 603 from damage and extending the service life of the equipment.

[0035] In a preferred embodiment, a sliding door 606 is provided on one side wall of the collection box 601, and a handle 608 is connected to the sliding door 606. The sliding door 606 usually adopts a push-pull or flip-up structure, and can be easily opened and closed by the handle 608, so that the staff can easily clean and maintain the metal shavings accumulated inside the collection box 601, thereby improving the daily maintenance efficiency of the equipment.

[0036] In a preferred embodiment, the piston rod of the hydraulic rod 8 drives the cutter 9 to reciprocate vertically. The hydraulic rod 8 provides a powerful instantaneous force through the hydraulic system, ensuring that the cutter 9 can quickly and accurately cut raw material wires of different materials and diameters, resulting in neat cut surfaces and improved production efficiency.

[0037] In a preferred embodiment, the housing 4 is provided with a guide structure for supporting the sliding of the adjustment component 5. The guide structure may be a guide rail and slider that cooperate with the sliding part of the adjustment component 5, or a precision-machined sliding groove, to ensure that the adjustment component 5 can maintain high precision and stability when it is adjusted in the radial and vertical directions, reduce vibration and deviation, and thus ensure the quality of the wound spring.

[0038] The working principle of this helical spring winding machine is as follows: During the winding operation, the raw material wire is first fed through the feeding assembly 3. The raw material passes through the two guide shafts 304 in the guide frame 302 and the guide wheel group 301 on the top of the base 303 in sequence to complete the initial guidance and feeding. Then, the raw material enters the transmission assembly 2. Under the joint clamping and driving of the upper guide wheel 201 and the lower guide wheel 202, the raw material is straightened and stably transported into the housing 4.

[0039] After entering the housing 4, according to the specifications of the spring to be processed, the control system precisely drives the adjustment component 5 to control the extension and retraction of the first electric push rod 501, so that its moving end drives the extrusion roller 503 to move in the horizontal direction to a predetermined position. This position determines the radius of the spring winding. At the same time, the control system controls the extension and retraction of the second electric push rod 502, so that its moving end drives the first electric push rod 501 and the extrusion roller 503 to move in the vertical direction to a predetermined position. This position determines the pitch of the spring winding.

[0040] After the parameters are set, the raw material begins to be wound and shaped under the action of the extrusion roller 503. When the spring reaches the preset number of turns, the hydraulic rod 8 at the bottom of the mounting plate 7 is activated, and its piston rod drives the cutter 9 to move downward, quickly cutting the raw material, and a complete spring is wound. At the moment the cutter 9 cuts, the exhaust fan 603 is started, and air is drawn into the collection box 601 through the air pipe 602, creating a negative pressure environment inside the collection box 601. Since the collection trough 604 is located below the cutter 9 and is connected to the collection box 601 through the pipe 605, the metal debris generated during the cutting process will fall into the collection trough 604 and be immediately sucked into the collection box 601 under the negative pressure. The filter screen 607 set inside the collection box 601 can prevent metal debris from entering the exhaust fan 603. After the debris accumulates to a certain amount, the operator can open the sliding door 606 through the handle 608 to clean the debris.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
