Description

Technical Field

[0001] This application relates to the technical field of caster production, and particularly to a spraying device for the automated production of caster parts. Background Art

[0002] In modern manufacturing, casters are widely used products, and their production efficiency and cost control are crucial for manufacturers. Currently, the production of casters generally adopts stamping forming technology for mass production to meet the market demand for high-quality and low-cost caster products. Stamping forming is a processing technology that applies pressure to a metal sheet through a mold to deform it into the required shape. The stamping forming technology can achieve continuous production, is suitable for large-scale mass manufacturing, and greatly improves production efficiency; using a mold for processing can also ensure the consistency of the size and shape of each product, which is beneficial to quality control; compared with other processing methods, the cost of stamping forming is lower, especially in large-scale production, which can significantly reduce the cost per unit product.

[0003] To ensure the smooth progress of the sheet metal during stamping, it is usually necessary to apply lubricating oil to the metal sheet before stamping. However, the currently commonly used manual application method is not only inefficient but also has safety hazards; it is very difficult to ensure a uniform oil film thickness on each sheet by manual lubrication application, which may cause the sheet to slide or jam during stamping, affecting product quality, and manual lubrication application takes a long time, and the production efficiency is significantly limited; on a stamping device, if only one worker is responsible for the operation, then during the stamping gap, the worker needs to reach into the front end position of the stamping to apply lubricating oil, and such an operation method is not only time-consuming and laborious but also has extremely high safety risks. Summary of the Invention

[0004] This device provides a spraying device for the automated production of caster parts, and the specific implementation is as follows:

[0005] A spraying device for the automated production of caster parts, comprising:

[0006] A spraying assembly disposed at the front end of the stamping device, and the material plate is introduced into the stamping device through a feeder;

[0007] The spraying assembly includes a seat body, a conduction cavity for the lateral penetration of the material plate is provided in the seat body, an oil tank, a liquid guide cam, and a brush roller are further installed on the seat body, a pressing drip head is provided at the bottom of the oil tank, both the liquid guide cam and the brush roller are connected with a driving part, the liquid guide cam intermittently acts on the pressing drip head or the brush roller, and the brush roller rotates to act on the material plate in the conduction cavity for lubricating oil application.

[0008] Based on the above technical solution, by installing a spraying component at the front end of the stamping equipment, it is possible to automatically spray lubricating oil evenly on the metal sheet, ensuring that the lubricating oil can evenly cover the surface of the sheet; the spraying component operates synchronously with the stamping equipment. When the metal sheet reaches the designated position, the spraying component automatically starts to complete the spraying operation of the lubricating oil; a rotatable liquid guide cam is provided, which cooperates with the pressing dropper in the oil tank. By rotating the cam, the opening and closing of the pressing dropper can be controlled, thereby achieving precise control of the oil discharge; the time that the liquid guide cam stays after rotation determines the amount of lubricating oil discharged from the oil tank. By adjusting the rotation speed and staying time of the cam, the amount of lubricating oil sprayed each time can be precisely controlled, further ensuring the uniformity and proper amount of coating.

[0009] Preferably, a first guiding roller set and a second guiding roller set are respectively provided at the corresponding positions of the front and rear ends of the seat body corresponding to the conduction cavity, and both are composed of guide rollers that abut against the upper and lower surfaces of the material plate.

[0010] Based on the above technical solution, by arranging the first guiding roller set and the second guiding roller set, the material plate is maintained in a stretched and straight state when being introduced into the seat body, making the oil coating more uniform.

[0011] Preferably, an oil-absorbing sponge is provided at the convex position on the circumferential surface of the liquid guide cam, and the oil-absorbing sponge abuts against the brush roller with an interference fit to transfer the lubricating oil.

[0012] Preferably, the oil tank is installed above the seat body through a bracket, and a plurality of pressing droppers are arranged along the length direction of the liquid guide cam at the bottom of the oil tank.

[0013] Preferably, there is a gap between the pressing dropper and the short diameter end of the liquid guide cam, and the lubricating oil flows out after it abuts against the long diameter end of the liquid guide cam.

[0014] Preferably, a first driving part and a second driving part are respectively connected to the ends of the liquid guide cam and the brush roller, and the two are respectively installed on both sides of the seat body.

[0015] Based on the above technical solution, the pressing droppers are arranged equidistantly and evenly along the length direction of the liquid guide cam, so that a single liquid guide cam can cover the long diameter end range of the same size of the liquid guide cam, making the oil on the entire long diameter end of the liquid guide cam uniform; through the contact between the relatively fixed liquid guide cam and the relatively slowly rotating brush roller, the transfer of the oil on the oil-absorbing sponge to the brush roller is realized.

[0016] Preferably, a liquid level sensor is installed in the oil tank.

[0017] Preferably, it further includes a controller, whose signal input end is electrically connected to the liquid level sensor, and the alarm, the first driving part and the second driving part are all electrically connected to its signal output end.

[0018] Based on the above technical solution, by setting up a controller and a liquid level sensor, the real-time monitoring of the oil volume in the oil tank can be achieved. When the oil is insufficient, the alarm is triggered for reminder, avoiding the influence on the subsequent stamping steps.

[0019] In summary, the present application includes the following beneficial technical effects:

[0020] 1. By adding a spraying component at the front end of the stamping equipment, the present utility model realizes the automatic lubricating oil application to the material plate; by setting a rotatable liquid guiding cam, it not only realizes the control of the oil discharge by acting on the pressing dropper, but also realizes the control of the oil discharge amount from the oil tank by controlling the staying time after rotation;

[0021] 2. By arranging the first guiding roller group and the second guiding roller group, the present utility model enables the material plate to maintain a stretched and straight state when being introduced into the seat body, making the oil application more uniform;

[0022] 3. The structure of the present utility model is simple. By setting up a controller and a liquid level sensor, the real-time monitoring of the oil volume in the oil tank can be achieved. When the oil is insufficient, the alarm is triggered for reminder, avoiding the influence on the subsequent stamping steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1

[0037] Referring to Figures 1 to 5 , this embodiment discloses a spraying device for the automatic production of caster parts, including a spraying component arranged at the front end of the stamping device 15. The material plate 11 is introduced into the stamping device 15 through a feeder. In this structure, the spraying component includes a seat body 1. A conduction cavity for the lateral penetration of the material plate 11 is provided inside the seat body 1. An oil tank 2, a liquid guide cam 5, and a brush roller 6 are also installed on the seat body 1. A pressing drip head 10 is provided at the bottom of the oil tank 2. The ends of the liquid guide cam 5 and the brush roller 6 are respectively connected to a first driving part 3 and a second driving part 4, and the two are respectively installed on both sides of the seat body 1. The liquid guide cam 5 intermittently acts on the pressing drip head 10 or the brush roller 6, and the brush roller 6 rotates to act on the material plate 11 in the conduction cavity for lubricating oil application.

[0038] First guiding roller groups 7 and second guiding roller groups 8 are respectively provided at the front and rear ends of the seat body 1 corresponding to the conduction cavity. Both are composed of guide wheels that abut against the upper and lower surfaces of the material plate 11. In this structure, an oil collecting groove with an upward opening can be provided below the liquid guide cam 5 to prevent the oil liquid directly dripping from the liquid guide cam 5 from mixing in and affecting the uniformity of the application to the material plate 11.

[0039] An oil-absorbing sponge is provided at the convex position on the circumferential surface of the liquid guide cam 5. The oil-absorbing sponge is in interference contact with the brush roller 6 to transfer the lubricating oil. The oil tank 2 is installed above the seat body 1 through the bracket 9. A plurality of pressing droppers 10 are arranged at the bottom of the oil tank 2 along the length direction of the liquid guide cam 5. In this structure, there is a gap between the pressing dropper 10 and the short diameter end of the liquid guide cam 5, and when it abuts against the long diameter end of the liquid guide cam 5, the lubricating oil flows out.

[0040] The specific implementation process is as follows: Under the action of the feeder, the material plate 11 is introduced into the stamping device 15; during this period, the brush roller 6 acts on the upper surface of the material plate 11 to apply the oil liquid; the first driving part 3 controls the liquid guide cam 5 to rotate correspondingly. When the liquid guide cam 5 corresponds to the oil tank 2, the oil-absorbing sponge of the liquid guide cam 5 acts on the pressing dropper 10 to open it, and the oil liquid in the oil tank 2 drips and adheres to the oil-absorbing sponge; when the liquid guide cam 5 corresponds to the brush roller 6, the brush roller 6 presses on the oil-absorbing sponge, so that the oil liquid is applied to the material plate 11.
