Description

Technical Field

[0001] This utility model relates to the field of stamping processing auxiliary equipment technology, and in particular to a stamping sheet metal oiling device. Background Technology

[0002] On the stamping production line, to prevent scratches and wear between sheet metal parts and dies, and to ensure the quality of stamped parts, lubricating oil needs to be applied to the surface of the sheet metal parts. Traditional oiling methods include manual brushing and spraying, but these methods have the following problems: manual oiling is inefficient and results in uneven coating; spraying oiling easily causes oil mist diffusion, polluting the environment; and the oil film thickness is difficult to control, affecting the quality of subsequent processing.

[0003] Chinese patent CN220836333 discloses a fully automatic double-sided oiling device for metal sheets. It uses an oil distribution chamber and a drip valve to supply oil to the upper oiling roller, and a regulating valve and a hollow roller body to supply oil to the lower oiling roller. This method has the following drawbacks: 1) Inaccurate oil quantity control: Relying on manual or coarse adjustment of valves makes it difficult to achieve precise synchronization with the stamping frequency, which can easily lead to too much or too little oil, resulting in waste or insufficient lubrication.

[0004] 2) Cannot be operated without human intervention: Due to the crude control method, the oil supply is continuous or semi-continuous, and it is impossible to achieve "on-demand oil supply". Operators need to monitor and adjust frequently, and it is impossible to truly achieve fully automated operation without human intervention.

[0005] 3) Complex system: It requires an oil dispersion chamber, multiple regulating valves, hollow rollers and complex sealing structures, resulting in high manufacturing and maintenance costs.

[0006] Therefore, there is an urgent need in this field for an oiling device that can achieve precise quantitative control, automatic control, and complete synchronization with the stamping production frequency, in order to solve the problems of oil waste, imprecise control, and inability to be operated independently. Summary of the Invention

[0007] The purpose of this invention is to solve the above-mentioned technical problems and provide a stamping sheet metal oiling device with simple structure, precise control, and the ability to achieve unmanned automatic operation.

[0008] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: a stamping sheet metal oiling device, comprising an oil supply system, a wool roller oiling mechanism, and a control system. The oil supply system includes an integrated oil storage and pump tank, a drip control solenoid valve, and at least one drip pipe. The integrated oil storage and pump tank serves as a constant pressure oil source, used to integrate and store oil and provide constant pressure to the system. The pump outlet of the integrated oil storage and pump tank is connected to the inlet of the drip control solenoid valve through a first pipeline. The outlet of the drip control solenoid valve is connected to the oil inlet channel of the throttling control valve base through a second pipeline. The throttling control valve base is provided with at least one oil outlet, and a throttling control valve is installed on each oil outlet. Each outlet of the throttling control valve is connected to a drip pipe. The control system is electrically connected to the drip control solenoid valve and controls the opening and closing frequency and the duration of each opening according to the number of times the stamping equipment operates, thereby achieving intermittent dripping of oil on demand and in a quantitative manner.

[0009] Preferably, the wool roller oiling mechanism includes an upper wool roller, a lower wool roller, and a wool roller bracket for mounting the upper and lower wool rollers, for uniformly applying oil to the surface of the sheet metal parts during rotation.

[0010] Preferably, the oil dripping pipe is positioned directly above the wool roller oiling mechanism, and the oil dripping nozzles of the oil dripping pipe are evenly arranged along the upper wool roller axis of the wool roller oiling mechanism.

[0011] Preferably, the length and / or angle of the oil drip tube is adjustable, so that the oil drip nozzle can be adjusted to align with the lower wool roller of the wool roller oiling mechanism to achieve double-sided oiling of the sheet metal parts.

[0012] Preferably, the throttling control valve base is provided with brackets on both sides for mounting the oil supply system on an external fixed platform.

[0013] Preferably, the control system is a PLC controller.

[0014] Compared with the traditional structure, the beneficial effects of this utility model are: 1. This utility model has a simple structure and reasonable design. It adopts a constant pressure oil source and solenoid valve control, and the PLC control system precisely controls the oil dripping according to the number of times or rhythm of the stamping equipment to achieve on-demand and quantitative oil dripping. This fundamentally solves the problem of excessive waste that is inevitable in traditional continuous oil supply methods, greatly reduces production costs, and is environmentally friendly and energy-saving.

[0015] 2. This utility model is simple to operate and easy to install. The device is linked with the stamping equipment, requiring no manual intervention, realizing truly automated continuous production without human intervention, improving the automation level of the production line and increasing production efficiency.

[0016] 3. This invention provides uniform oil application, stable quality, and controllable oil film thickness. The constant pressure source ensures consistent oil flow rate and volume with each drop, and combined with the axially evenly distributed oil nozzles, it ensures uniform wetting of the wool roller, thereby forming a uniform oil film on the sheet metal surface and improving the consistency of stamping quality.

[0017] 4. The modular integrated oil storage pump tank and solenoid valve result in a simpler structure, lower failure rate, easier maintenance, and easy integration with existing stamping equipment. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below.

[0020] See attached document Figure 1 A stamping sheet metal oiling device includes an oil supply system, a wool roller oiling mechanism, and a control system. The oil supply system includes an integrated oil storage and pump tank 1, a drip control solenoid valve 2, and at least one drip pipe 8. The integrated oil storage and pump tank 1 serves as a constant pressure oil source, used to integrate and store oil and provide a constant pressure for the system. The pump outlet of the integrated oil storage and pump tank 1 is connected to the inlet of the drip control solenoid valve 2 via a first hose. The outlet of the drip control solenoid valve 2 is connected to the oil inlet channel of the throttling control valve base 3 via a second hose. The throttling control valve base 3 is provided with at least one oil outlet, and a throttling control valve 7 is installed on each oil outlet. Each outlet of the throttling control valve 7 is connected to a drip pipe 8. The control system is electrically connected to the drip control solenoid valve 2 and controls the opening and closing frequency and the duration of each opening according to the number of times the stamping equipment operates, so as to realize intermittent dripping of oil on demand and in a quantitative manner.

[0021] In this preferred embodiment, the wool roller oiling mechanism includes an upper wool roller 4, a lower wool roller 5 arranged opposite to each other, and a wool roller bracket 10 for mounting the upper wool roller 4 and the lower wool roller 5, for uniformly applying oil to the surface of the sheet metal part 6 that passes through during rotation.

[0022] In this preferred embodiment, the oil dripping pipe 8 is positioned directly above the wool roller oiling mechanism, and the oil dripping nozzles of the oil dripping pipe 8 are evenly arranged along the axial direction of the upper wool roller 4 of the wool roller oiling mechanism.

[0023] In this preferred embodiment, the length and / or angle of the oil dripping pipe 8 are adjustable, so that its dripping nozzle can be adjusted to align with the lower wool roller 5 of the wool roller oiling mechanism, so as to achieve double-sided oiling of the sheet metal part 6.

[0024] In this preferred embodiment, brackets 9 are provided on both sides of the throttle control valve base 3 for mounting the oil supply system on an external fixed platform.

[0025] In this preferred embodiment, the control system is a PLC controller.

[0026] In practice, the integrated oil storage tank 1, acting as a constant pressure source, is filled with a constant air pressure to ensure stable outlet oil pressure. The stamping oil is pumped from the integrated oil storage tank 1 to the drip control solenoid valve 2. This solenoid valve is precisely controlled by a PLC controller, which is connected to the main control system of the stamping equipment to acquire the stamping frequency signal in real time, achieving quantitative oil supply per stroke. When the drip control solenoid valve 2 is opened, the stamping oil is pumped to the throttling control valve 7 for final fine-tuning and stabilization of the flow rate. Then, it enters the drip pipe 8, which is suspended directly above the upper wool roller 4. The drip nozzle on the pipe is aligned with the upper wool roller 4, and the oil is delivered by gravity or pump and drips onto the uniformly rotating upper wool roller 4, where it is evenly spread. The sheet metal part 6 is advanced by the feeder, passing between the upper wool roller 4 and the lower wool roller 5. Friction during its advancement drives the wool rollers to rotate, thus evenly coating the surface of the sheet metal part 6 with stamping oil.

[0027] To achieve double-sided oiling, part of the drip nozzle of the oil dripping pipe 8 can be adjusted to align with the lower wool roller 5, or the oil accumulated on the upper wool roller 4 can be replenished by gravity dripping naturally onto the lower wool roller 5. The number of throttling control valves 7 and oil dripping pipes 8 can be increased or decreased according to actual conditions. The entire device is fixed to a fixed platform such as the stamping equipment or feeding machine table via the bracket 9 and wool roller bracket 10, featuring a compact structure and convenient installation.
