Description

Technical Field

[0001] The invention relates to the technical field of broaching devices, and more particularly to a segmented cutting fluid wastewater treatment device and method for machining machine tool accessories. Background Art

[0002] Machine tool accessories are auxiliary devices used to expand the processing performance and application range of machine tools. There are many types of machine tool accessories, including flexible accordion-type protective covers (leather tigers), steel plate stainless steel guide rail protective covers, telescopic screw protective covers, rolling curtain protective covers, adjustable plastic cooling pipes, travel slot plates, guide rail scraper plates and various operating parts.

[0003] In the production and processing of machine tool accessories, the broaching device is often used to process various holes, keyways, etc., and is an important production equipment in the production and processing of machine tool accessories. When the workpiece used to produce machine tool accessories is processed by the broaching device, in order to save production costs and improve resource utilization, the cutting fluid is often recycled. However, in the process of the broaching device producing machine tool accessories and recycling the cutting fluid, the cutting fluid is prone to produce floating oil on the surface of the cutting fluid due to equipment leakage, impurity contamination, bacterial growth, etc. The current method for dealing with the floating oil produced in the cutting fluid is often to use a filter to separate the debris and impurities produced in the broaching process after the production and processing of the machine tool accessories is completed. The separated cutting fluid is then placed in a sedimentation tank and left to stand for a period of time. After that, the staff uses tools such as spoons to clean up the floating oil above the cutting fluid. The staff discharges the cutting fluid at the top for reuse, and finally cleans up the slag at the bottom of the cutting fluid.

[0004] The above process is time-consuming and has a poor effect on cleaning the floating oil generated in the cutting fluid, which not only reduces the production and processing efficiency of machine tool accessories, but also makes it easy for the floating oil to adhere to the surface of the workpiece during the recycling of the cutting fluid to form an oil layer, causing pollution to the workpiece. This not only hinders the cleaning effect of the cutting fluid on the broaching area, but also makes it impossible to discharge the debris in the broaching area in time, affecting the processing effect of the machine tool accessories. Moreover, after the floating oil adheres to the surface of the workpiece, it will also affect the cleanliness of the finished machine tool accessories, increasing the difficulty and cost of cleaning in the subsequent processes.

[0045] The collecting liquid box in the nozzle unit is also connected to the pulling machine.

[0046] The technical solution of the present invention provides a wastewater treatment method of a segmented cutting fluid wastewater treatment device for machine tool accessory processing, comprising the following steps:

[0047] S1. When making machine tool accessories through broaching equipment, spray cutting fluid to the part of the workpiece being broached through the processing structure;

[0048] S2. The cutting fluid sprayed on the workpiece surface flows down along the workpiece surface and is transported to the fluid storage unit for unified collection;

[0049] S3, the fluid storage unit pumps the cutting fluid into the water guide part in the main processing unit through the pumping part;

[0050] S4, the cutting fluid is output from the water guide part, and then the floating oil in the cutting fluid is intercepted and filtered by the filter element, and the filtered cutting fluid is then sprayed out by the nozzle unit;

[0051] S5. When the filter element in the main processing unit is clogged, the cutting fluid drives the sealing component to elastically retract, and the cutting fluid flows to the inside of the spare processing unit through the bypass duct, and is filtered by the filter element before being transported to the nozzle unit. In addition, the movable sealing component also synchronously drives the sliding vane part to slide on the surface of the resistor part.

[0052] Beneficial effects: One or more technical solutions provided in the technical solution of the present invention have at least the following technical effects or advantages: 1. Cutting fluid is sprayed into the broaching area through the processing structure, and the cutting fluid flows down along the surface of the workpiece and then passes through the filter to filter out impurities such as debris mixed in the cutting fluid, thereby realizing the initial treatment of the cutting fluid. Subsequently, the cutting fluid is transported to the inside of the fluid storage unit for unified collection, and most of the floating oil floating on the surface of the cutting fluid is absorbed by the oil absorption layer in the fluid storage unit, thereby reducing the burden of subsequent filtration of the filter element, thereby realizing the mid-stage treatment of the cutting fluid. Subsequently, the fluid storage unit is pumped to the main processing unit through the pumping element. The cutting fluid is pumped inside the water guide part. After the cutting fluid is output by the water guide part, the remaining floating oil in the cutting fluid is intercepted and filtered by the filter element, thereby realizing the final treatment of the cutting fluid, so that the cutting fluid is deeply purified. The filtered cutting fluid is then sprayed out by the nozzle unit, so that during the production and processing of machine tool accessories, the device can gradually remove impurities and floating oil in the cutting fluid through a segmented treatment method, thereby ensuring the purification effect of the cutting fluid. Therefore, during the production and processing of machine tool accessories, it not only helps to improve the production and processing efficiency of machine tool accessories, but also can effectively avoid the occurrence of floating oil in the cutting fluid adhering to the surface of the workpiece, thereby ensuring the broaching effect of the workpiece.

[0053] 2. After the cutting fluid is output by the water guide part, the floating oil in the cutting fluid is intercepted and filtered by the filter element located in the main processing unit. When the filter element in the main processing unit is blocked, the cutting fluid drives the sealing component to elastically shrink, and the cutting fluid flows to the inside of the standby processing unit through the bypass duct, thereby triggering the standby processing unit to be activated. After being filtered by the filter element in the standby processing unit, the cutting fluid is transported to the nozzle unit to spray the cutting fluid to the broaching area again, avoiding the situation of shutdown due to obstruction of the circulation of the cutting fluid after blockage occurs in the process of filtering the cutting fluid in the main processing unit, thereby ensuring that the cutting fluid can be continuously and stably supplied to the broaching area during the production and processing of machine tool accessories, while ensuring the broaching effect of the workpiece, it also helps to maintain the high processing efficiency of the machine tool accessories.

[0054] 3. When the filter element in the main processing unit is clogged, causing the cutting fluid to drive the sealing component to elastically retract, the active sealing component will also synchronously drive the sliding part to slide on the surface of the resistor part, so that the distance between the elastic pressing plate in the sliding part and the static terminal in the resistor part is shortened, and fewer lines in the resistance wire of the variable resistance module are collected between the elastic pressing plate and the static terminal, the resistance value is reduced, and the output power of the second water pump in the pumping part is also increased accordingly, so that when the main processing unit is clogged and the cutting fluid is transferred from the main processing unit to the inside of the spare processing unit, the circulation rate of the cutting fluid is improved, ensuring that the cutting fluid can pass through the filter element inside the spare processing unit faster and be transported to the broaching area, thereby shortening the time when the cutting fluid supply in the broaching area is suddenly reduced due to the blockage of the main processing unit and the cutting fluid is transferred from the main processing unit to the inside of the spare processing unit, so that the cutting fluid can accelerate to flow to the broaching area, greatly reducing the probability of workpiece deformation or reduced processing accuracy due to insufficient cutting fluid in the above time period, and improving the stability of the broaching process of machine tool accessories.

[0055] 4. When the filter element in the main processing unit is clogged, the cutting fluid continuously flows into the upper end cavity through the guide channel, and drives the switch moving terminal in the warning component to approach the switch fixed terminal through the spring-loaded piston in the sealing component. When the switch moving terminal contacts the switch fixed terminal, the alarm is triggered to turn on, so that the filter element in the main processing unit becomes clogged and fails, and the cutting fluid drives the sealing component to elastically retract. In this process, the warning component is triggered to send a fault alarm signal to the operator, reminding the staff to clean the filter element in time after the machine tool accessories are broached, so as to ensure the reliability and safety of the equipment operation.

[0107] The resistor body part includes a cover connected to the bottom end of the vertical stand 213 and covering the opening at the end of the lower end cavity. The cover is connected to an insulating support rod on one side close to the lower end cavity. A spirally wound resistance wire 222 is wound around the insulating support rod. A static terminal 223 is also connected to the insulating support rod.

[0108] The end of the lower cavity is provided with a positioning groove matched with the insulating support rod, and one end of the insulating support rod away from the cover is movably inserted into the positioning groove;

[0109] The sliding piece part includes an insulating traction rod, and an elastic pressing piece 224 is connected to the side wall of one end of the insulating traction rod;

[0110] One end of the insulating traction rod away from the elastic pressing piece 224 is sealed and penetrated into the upper end cavity and connected to the elastic pressing piston 226 in the sealing component;

[0111] The free end of the elastic pressing piece 224 in the sliding piece part is always in close contact with the surface of the passive ejector rod 220 which is spirally wound in the resistor body part;

[0112] The elastic pressing piece 224 , the resistance wire 222 and the static terminal 223 are all electrically connected to the second water pump 211 in the pumping member.

[0113] When the filter element in the main processing unit is clogged, the cutting fluid drives the sealing component to elastically retract, and the movable sealing component will synchronously drive the sliding piece to slide on the surface of the resistor body, so that the distance between the elastic pressing piece 224 in the sliding piece and the static terminal 223 in the resistor body is shortened, and fewer lines in the resistance wire 222 of the variable resistance module are collected between the elastic pressing piece 224 and the static terminal 223, the resistance value is reduced, and the output power of the second water pump 211 in the pumping part is also increased, so that the main processing unit is blocked and the cutting fluid is discharged from the main processing unit. In the process of turning to the spare processing unit, the circulation rate of the cutting fluid is increased to ensure that the cutting fluid can pass through the filter element inside the spare processing unit faster and be transported to the broaching area, thereby shortening the time when the cutting fluid supply in the broaching area suddenly decreases due to blockage in the main processing unit and the cutting fluid is turned from the main processing unit to the spare processing unit. This allows the cutting fluid to flow to the broaching area at an accelerated speed, greatly reducing the probability of workpiece deformation or reduced machining accuracy due to insufficient cutting fluid during the above time period, thereby improving the stability of the broaching process of machine tool accessories.

[0114] Reference Figures 2 to 5 as well as Figures 6 to 8 , the embodiment of the present invention provides a segmented cutting fluid wastewater treatment device for machine tool accessory processing, the warning component includes an insulating slide seat sliding in the inner cavity of the insulating inner cylinder seat 209 and an alarm 203 connected to the top of the insulating inner cylinder seat 209;

[0115] The alarm 203 is connected to a switch fixed terminal 214, and one end of the switch fixed terminal 214 away from the alarm 203 extends into the inner cavity of the insulating inner cylinder seat 209, and the insulating slide seat is connected to a switch movable terminal 207 on the side close to the switch fixed terminal 214, and the switch fixed terminal 214 and the switch movable terminal 207 are arranged opposite to each other, and a second return spring is connected to the other side of the insulating slide seat, and one end of the second return spring away from the insulating slide seat is connected to one end of the passive ejector 220 extending into the inner cavity of the insulating inner cylinder seat 209;

[0116] The switch fixed terminal 214 and the switch movable terminal 207 are both electrically connected to the alarm 203 .

[0117] When the filter element in the main processing unit is clogged, the cutting fluid continuously flows into the upper end cavity through the guide channel, and drives the switch moving terminal 207 in the warning component to approach the switch fixed terminal 214 through the spring-loaded piston 226 in the sealing component. When the switch moving terminal 207 contacts the switch fixed terminal 214, the alarm 203 is triggered to open, so that when the filter element in the main processing unit is clogged and fails, and the cutting fluid drives the sealing component to elastically retract, the warning component is triggered to send a fault alarm signal to the operator, reminding the staff to clean the filter element in time after the machine tool accessories are broached, so as to ensure the reliability and safety of the equipment operation.

[0118] The embodiment of the present invention provides a wastewater treatment method of a segmented cutting fluid wastewater treatment device for machine tool accessory processing, comprising the following steps:

[0119] S1. When making machine tool accessories through broaching equipment, spray cutting fluid to the workpiece part undergoing broaching through the processing structure;

[0120] S2. The cutting fluid sprayed on the workpiece surface flows down along the workpiece surface and is transported to the fluid storage unit for unified collection;

[0121] S3, the fluid storage unit pumps the cutting fluid into the water guide part in the main processing unit through the pumping part;

[0122] S4, the cutting fluid is output from the water guide part, and then the floating oil in the cutting fluid is intercepted and filtered by the filter element, and the filtered cutting fluid is then sprayed out by the nozzle unit;

[0123] S5. When the filter element in the main processing unit is clogged, the cutting fluid drives the sealing component to elastically retract, and the cutting fluid flows to the inside of the spare processing unit through the bypass duct 217, and is filtered by the filter element before being transported to the nozzle unit. In addition, the movable sealing component also synchronously drives the sliding vane part to slide on the surface of the resistor part.
