Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, specifically to an anti-rust spraying device for spring production. Background Technology

[0002] As is well known, springs are a key basic component of mechanical equipment, and their rust-proof performance directly determines the service life and operational stability of the equipment. Therefore, rust-proof painting is one of the core processes in spring production. Currently, the mainstream rust-proof painting methods for springs in the industry have the following prominent problems: Most devices rely on manual labor to move the springs to the painting position, which is not only inefficient, but also makes it difficult to ensure that the springs are in a stable position during the painting process. Slight deviations can easily lead to missed areas in the painting process. Although some semi-automatic devices have a conveying structure, they lack a positioning design that is adapted to the spiral shape of the springs. The springs are prone to shaking during the conveying process, which further aggravates the painting deviation.

[0003] Existing fixed spray painting equipment cannot flexibly adjust its height, angle, and spray range according to the specifications of the spring, such as its length (50-500mm) and diameter (5-50mm). For helical spring workpieces, the fixed spray head can only cover a local surface, and the gap between the helix and the end face are prone to forming paint dead zones, resulting in less than 60% integrity of the anti-rust paint coverage, and there is still a risk of rust during subsequent use.

[0004] To solve the problem of blind spots in painting, it is usually necessary to add many nozzles to ensure uniform painting. For example, a spring-loaded painting device disclosed in patent number CN213409149U includes a top plate, a bottom plate, and a fixed plate. The fixed plate is vertically set in the middle of the bottom plate, and the bottom of the fixed plate is connected to the top of the bottom plate. The top plate is horizontally set on top of the fixed plate, and the middle of the top plate is connected to the top of the fixed plate. A first fixed block is provided on the bottom left side of the top plate, and the top of the first fixed block is connected to the bottom left side of the top plate. A first groove is formed on the bottom of the first fixed block, and the bottom of the first groove has an opening. A second fixed block is provided on the top left side of the bottom plate, and the bottom of the second fixed block is connected to the top left side of the bottom plate. A second groove is formed on the top of the second fixed block, and the top of the second groove has an opening. A first sliding rod is provided in the second groove, and the bottom and top of the first sliding rod are connected to the second groove. Although it can spray paint evenly, the large number of nozzles will cause paint waste and thick paint spraying.

[0005] The aforementioned problems make it difficult for existing equipment to balance paint quality, production efficiency, and environmental compliance. There is an urgent need for an integrated device that can achieve precise workpiece transfer, flexible nozzle adjustment, multi-directional painting, and effective control of paint mist.

[0008] Furthermore, the sliding mechanism includes a sliding groove and a slide rail. The sliding groove is formed at the top of the spray booth, and the slide rail is installed at the top of the spray booth and is equipped with an electric slider. One end of the electric slider is equipped with an L-shaped bracket. The L-shaped bracket passes through the sliding groove and extends into the interior of the spray booth.

[0009] Furthermore, the ventilation mechanism includes ventilation pipes installed on both sides of the paint spray booth, and electric valves are provided on the ventilation pipes.

[0010] Furthermore, a pulley is provided between the L-shaped bracket and the sliding groove.

[0011] Furthermore, the pulleys are provided in two symmetrical arrangement.

[0012] Furthermore, there are two second nozzles arranged symmetrically.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a rust-proof spraying device for spring production, which has the following beneficial effects: This rust-proof painting device for spring production automates the transfer of spring workpieces through a sliding mechanism. After being fixed, the workpiece is precisely inserted into the painting area along the groove in the painting chamber without manual intervention. With the help of the telescopic device in the adjustment groove and the rotating motor at the bottom of the worktable, the height of the adjustment column (adjustment range 0-300mm) and the rotation speed (0-60r / min) can be flexibly adjusted according to the spring size, so that the first spray head at the top and side can fit the changes in the length and diameter of the spring. Together with the second spray head symmetrically tilted at the top of the support ring, a multi-directional coverage structure of rotating spraying plus fixed oblique spraying is formed, which improves the integrity of the rust-proof paint coverage and completely solves the problem of paint omissions in the spiral gap and end face.

Detailed Implementation

[0016] 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.

[0017] Please see Figures 1-4This utility model relates to a rust-proof spray painting device for spring production, comprising a workbench 1, a spray painting chamber 2 on the workbench 1, slots on both sides of the spray painting chamber 2, a sliding mechanism and a ventilation mechanism on the spray painting chamber 2, the sliding mechanism for moving the spring workpiece, an adjustment groove at the top of the workbench 1, a telescopic device 3 within the adjustment groove, a bearing seat 4 between the telescopic device 3 and the adjustment groove, a rotary motor 5 at the bottom of the workbench 1, the output end of the rotary motor 5 extending into the adjustment groove and fixed to the bottom of the telescopic device 3, a support ring 6 at the top of the telescopic device 3, and an adjustment column 7 at the output end of the telescopic device 3. The top and one side of the adjusting column 7 are each provided with a first nozzle 8. The support ring 6 has a guide pipe 9 inside. Between the guide pipe 9 and the outside of the support ring 6, there is an inlet pipe 10 and a conveying pipe 11. The conveying pipe 11 extends into the interior of the adjusting column 7 and connects to the two first nozzles 8. The top of the support ring 6 is provided with a second nozzle 19, which is inclined. The second nozzle 19 connects to the guide pipe 9. In this embodiment, the spring workpiece to be painted is fixed by a sliding mechanism. Simultaneously, the inlet pipe 10 connects to a pipe providing rust-preventive paint. The inlet pipe 10 conveys rust-preventive paint to the guide pipe 9 inside the support ring 6. The paint is then diverted through the guide pipe 9 to the conveying pipe 11 and the second nozzle 19. The sliding mechanism is activated, moving the fixed spring workpiece along the slots on both sides of the spray booth 2 into the interior of the spray booth 2, positioning it in the corresponding area of ​​the support ring 6 and the adjusting column 7. Based on the length, diameter, and other dimensions of the spring, the height of the adjusting column 7 is adjusted (adjustment range 0-300mm) via the telescopic device 3 within the adjusting groove. The output end of the telescopic device 3 drives the adjusting column 7 to rise and fall, simultaneously activating the rotary motor 5 at the bottom of the workbench 1. The output end of the rotary motor 5 drives the telescopic device 3 to rotate around the bearing seat 4, thereby causing the adjusting column 7 and the first nozzles 8 on its top and side to rotate synchronously. Paint enters the interior of the adjusting column 7 through the feed pipe 11 and is sprayed by the top and side of the two first nozzles 8; simultaneously, the first nozzle 8, which is inclined at the top of the support ring 6... Two nozzles 19 spray paint synchronously. The rotating first nozzle 8 and the fixed-angle second nozzle 19 form a multi-directional paint coverage. The painting power is provided by a booster pump commonly used in the prior art. The booster pump is connected to the pipeline for supplying paint through the feed pipe 10 to drive the anti-rust paint to be transported sequentially through the guide pipe 9 and the conveying pipe 11 to the first nozzle 8 and the second nozzle 19 to achieve the painting process. During the painting process, the ventilation mechanism is activated to treat the paint mist through the airflow in the paint chamber 2. After the painting is completed, the sliding mechanism moves the spring workpiece out of the paint chamber 2.

[0018] In this design, the sliding mechanism includes a sliding groove and a slide rail 12. The sliding groove is located at the top of the spray booth 2. The slide rail 12 is mounted at the top of the spray booth 2 and has an electric slider 13. One end of the electric slider 13 has an L-shaped bracket 14. The L-shaped bracket 14 passes through the sliding groove and extends into the interior of the spray booth 2. The L-shaped bracket 14 has a slot and a hook 15. The electric slider 13 slides along the slide rail 12, thereby driving the L-shaped bracket 14 to slide along the sliding groove. The slot of the L-shaped bracket 14 cooperates with the hook 15 to suspend and fix the spring workpiece, ensuring the stability of the workpiece position during transfer and spraying. The suspension method of the hook 15 avoids contact and obstruction between the spring and the supporting components, ensuring the integrity of the spraying. The electric slider 13 has high driving precision and controllable transfer position. The electric slider 13 can be an existing small ball screw electric slider 13.

[0019] In this solution, the ventilation mechanism includes ventilation pipes 16, which are installed on both sides of the spray booth 2. The ventilation pipes 16 are equipped with electric valves 17. The ventilation mechanism connects to external air supply and exhaust pipes through the ventilation pipes 16 on both sides to form a convective airflow. The electric valves 17 control the opening and closing of the ventilation pipes 16 and the air volume to achieve the directional discharge of paint mist in the spray booth 2.

[0020] In this design, a pulley 18 is provided between the L-shaped bracket 14 and the sliding groove. The pulley 18 between the L-shaped bracket 14 and the sliding groove converts sliding friction into rolling friction, reducing the resistance on the contact surface between the two. By reducing the coefficient of friction through the pulley 18, the sliding becomes smoother and component wear is reduced. Two pulleys 18 are provided and symmetrically arranged. The two symmetrically arranged pulleys 18 ensure that the contact force between the L-shaped bracket 14 and the sliding groove is evenly distributed, avoiding tilting or jamming caused by unilateral force.

[0021] In this design, there are two second nozzles 19 arranged symmetrically. The two symmetrically tilted second nozzles 19 form a symmetrical spray area, which complements the rotating spray of the first nozzle 8 and covers the dead corner above the side of the spring.

[0022] Drive motor type: AC servo motor, such as Panasonic MSME082G1U (0.75kW) or Delta ECMA-C20807ES (0.75kW). Telescopic device type: Electric linear actuator, such as Topda TD-800-50 (800N thrust, 50mm stroke) or Gewa Drive GWD-050-800 (800N thrust, 50mm stroke). The above component models are recommended selections; in actual implementation, they can be replaced with other brands of products with the same parameters (e.g., the drive motor can be replaced with a Siemens V90 series).

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
