Description

Technical Field

[0001] This utility model relates to the field of cutting fluid replenishment technology for threading machines, specifically an automatic cutting fluid replenishment device for a rebar threading machine. Background Technology

[0002] Threading machines are specialized equipment used to cut external threads on the ends of metal pipes and bars. They are characterized by high efficiency and precision. They are driven by electricity or hydraulics and use adjustable dies or thread combs to quickly process standard threads. They are suitable for hydropower installation, construction engineering and machinery manufacturing. During the threading process, cutting fluid needs to be sprayed at the rotating thread rolling cutter to lubricate the cutter head, thereby improving the threading quality.

[0003] A search revealed a Chinese patent with publication number CN215199999U that discloses a threading machine for building decoration, comprising a frame and a threading machine body mounted on the frame. The threading machine body is characterized by having a cooling assembly, which includes a cooling cylinder for holding cutting fluid, with a fluid supply pipe connected to the lower end of the cooling cylinder.

[0004] While the above-mentioned solutions can recover cutting fluid, in actual use, operators often need to observe the cutting fluid level in the cooling tank and manually add cutting fluid when it is low. This method can easily lead to delays in cutting fluid replenishment, causing deviations in the machining accuracy of rebar threads, abnormal tool wear, and increasing the risk of personnel accidentally touching rotating parts. To address these issues, we provide an automatic cutting fluid replenishment device for rebar threading machines. Utility Model Content

[0024] like Figure 1 As shown, this utility model provides a technical solution for an automatic cutting fluid replenishment device for a rebar threading machine, including a threading machine body 1. A power supply is installed inside the threading machine body 1. Through the setting of the power supply, power can be supplied to the electrical equipment in this application. A cutting device and a positioning device are installed on the top surface of the threading machine body 1. The cutting device and the positioning device are existing technologies and are not the focus of this application, so they will not be described in detail.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic mechanism 2 is provided above the threading machine body 1. The automatic mechanism 2 includes a support frame 201. The bottom surface of the support frame 201 is slidably connected to the threading machine body 1. The support frame 201 is fixedly connected to the cutting equipment.

[0026] An output tank 202 is fixedly connected to the inner top wall of the support frame 201. A piston disc 203 is slidably connected to the inner wall of the output tank 202. A slide rod 204 is fixedly connected to the top surface of the piston disc 203. The outer surface of the slide rod 204 is slidably connected to the support frame 201 and the output tank 202. When the cutting fluid level in the output tank 202 changes, the slide rod 204 can slide vertically simultaneously in the inner walls of the support frame 201 and the output tank 202.

[0027] A connecting plate 205 is fixedly connected to the end of slide rod 204 away from piston disc 203. Slide rod 206 and slide rod 207 are fixedly connected to the bottom surface of connecting plate 205. Slide rod 206 and slide rod 207 are slidably connected to the support frame 201. Sealing gaskets are installed between slide rod 204, slide rod 206 and slide rod 207 and the support frame 201. The sealing gaskets can effectively prevent external dust from entering and affecting the vertical sliding of the three in the support frame 201.

[0028] Pressure sensor 1 208 is fixedly connected to the inner wall of the support frame 201, and pressure sensor 209 is fixedly connected to the inner wall of the support frame 201. A controller is installed inside the threading machine body 1. When pressure sensor 1 208 and pressure sensor 209 sense the displacement pressure of slide bar 206 and slide bar 3 207, they can effectively send commands to the controller. The controller can open and close the pump body 213 upon receiving the command.

[0029] A pump body 210 is fixedly connected to the inner bottom wall of the output tank 202. A delivery pipe 211 is fixedly connected to the output end of the pump body 210. The end of the delivery pipe 211 away from the pump body 210 passes through the output tank 202 and is fixedly connected to the output tank 202. The control button of the pump body 210 is integrated on the outer surface of the support frame 201. The pump body 210 can be started and stopped by the control button. By starting the pump body 210, the cutting fluid in the output tank 202 can be effectively pumped out through the delivery pipe 211.

[0030] A storage tank 212 is fixedly connected to the inner wall of the support frame 201. A pump body 213 is fixedly connected to the inner bottom wall of the storage tank 212. A delivery pipe 214 is fixedly connected to the output end of the pump body 213. The end of the delivery pipe 214 away from the pump body 213 passes through the storage tank 212 and is fixedly connected to the output tank 202. The pump body 210, pump body 213, pressure sensor 208, pressure sensor 209, and the controller mentioned in this application are all common electrical devices and electrical components in the prior art. This application will not elaborate on their models and internal structures.

[0031] like Figure 1 and Figure 4 As shown, the threading machine body 1 is equipped with a recycling mechanism 3 inside. The recycling mechanism 3 includes a recycling box 301. The top surface of the recycling box 301 is fixedly connected to the threading machine body 1. The inner wall of the recycling box 301 is fixedly connected with a filter plate 302 and a filter plate 303. Through the setting of the filter plate 302 and the filter plate 303, the cutting fluid after use can be effectively filtered multiple times, which is convenient for the next use.

[0032] A scraper 304 is slidably connected to the inner wall of the recycling bin 301. A connecting rod 305 is fixedly connected to the outer surface of the scraper 304. The outer surface of the connecting rod 305 is slidably connected to the recycling bin 301. A debris box 307 is slidably connected to the inner wall of the recycling bin 301. A sealing plug is fixedly installed on the outer surface of the debris box 307. The sealing plug can prevent the cutting fluid in the recycling bin 301 from overflowing. By driving the connecting rod 305, the scraper 304 can be moved to effectively scrape and clean the debris on the filter plate 302, so that the debris can be collected and recycled into the debris box 307.

[0033] A limiting slider 306 is fixedly connected to the outer surface of the connecting rod 305. The outer surface of the limiting slider 306 is slidably connected to the threading machine body 1. By setting the limiting slider 306, the connecting rod 305 is effectively limited, making the connecting rod 305 more stable when moving.

[0034] The structural diagrams of the components shown in the attached figures are exemplary. The specific implementation should be adapted and optimized by considering the functional requirements, assembly conditions and process limitations in the actual application scenario, and adjusting the structural parameters, size specifications and connection methods accordingly.

[0035] Working principle: First, when the pump body 210 is started, drawing cutting fluid from the output tank 202 and outputting it through the delivery pipe 211, the liquid level continuously drops, causing the piston disc 203 to slide down synchronously within the inner wall of the output tank 202. The downward movement of the piston disc 203 drives the sliding rod 204 to move downwards, which in turn drives the sliding rod 206 on the bottom surface of the connecting plate 205 to move downwards simultaneously. When the sliding rod 206 contacts the pressure sensor 208, it indicates that the cutting fluid in the output tank 202 has reached its limit and needs to be replenished. Because the pressure sensor 208... Sensing the downward pressure of slide bar 206, the controller inside the threading machine body 1 immediately sends a command. Upon receiving the command, the controller immediately starts pump body 213. Pump body 213 draws the cutting fluid from storage tank 212 and delivers it to output tank 202 through delivery pipe 214. The rise in cutting fluid in output tank 202 pushes piston disc 203 upward. The upward movement of piston disc 203 causes connecting plate 205 at one end of slide bar 204 to move upward simultaneously. The upward movement of connecting plate 205 pulls slide bar 207 upward. When pressure sensor 209 is activated, it indicates that the cutting fluid in output tank 202 has reached saturation. Pressure sensor 209 then senses the upward pressure of slide bar 307 and immediately sends a command to the controller. Upon receiving the command, the controller immediately shuts off pump 213, preventing further replenishment of cutting fluid into output tank 202. This allows the device to automatically identify and replenish the cutting fluid level in output tank 202 without manual judgment or addition, solving the problem of delayed cutting fluid replenishment caused by traditional manual operation. It effectively avoids deviations in the precision of rebar threading and abnormal tool wear, while significantly reducing the risk of accidental contact with rotating parts. Furthermore, the used cutting fluid falls directly into the recovery tank 301. After double filtration by filter plate 302 and filter plate 303, the cutting fluid is collected at the bottom of the recovery tank 301 for convenient reuse. This optimization effectively saves on cutting fluid usage, significantly reducing enterprise consumable costs. The device improves processing efficiency while maintaining economic benefits, fully demonstrating technological innovation and practical value.
