Technical Field

[0001] The present invention belongs to the technical field of metal turning equipment, and particularly relates to a martensitic stainless steel turning equipment. Background Art

Specific implementation

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] The defect of the existing martensitic stainless steel turning equipment is that when turning martensitic stainless steel, the waste generated by turning, that is, chips, has the value of recycling. However, in the actual operation process, due to the need to add cutting fluid during turning, the chips generated by turning will be mixed with the cutting fluid and fly everywhere, making it difficult to collect and recycle the chips.

[0041] To solve the above problems, the main concept adopted in this embodiment is: the cutting fluid drives the air blowing device to work, and through the cooperation of the air blowing device and the agglomeration and filtration device, the collection and recycling of chips are realized.

[0042] To better understand the above technical solutions, the following will be combined with the attached Figures 1-4 And specific implementation manners to describe the above technical solutions in detail:

[0043] A martensitic stainless steel turning equipment provided by the present invention includes an equipment main body and a main shaft 1. A motor is provided at the bottom of the equipment main body, and a turning chamber is provided inside the equipment main body. A workbench 3 and a tool rest 2 are provided in the turning chamber. The bottom of the workbench 3 is fixedly connected to the main shaft 1, and the main shaft 1 cooperates with the motor. A support base 4 is fixedly connected to the outer surface of the main shaft 1. The bottom end of the support base 4 is rotatably connected to the bottom of the turning chamber, and the upper end surface of the support base 4 is fixedly connected to the lower surface of the workbench 3. The turning chamber further includes:

[0044] An agglomeration and filtration device 5, which surrounds the support base 4 and performs agglomeration and filtration treatment on the chips generated by turning;

[0045] An air blowing device 6, which is located on one side of the agglomeration device close to the inner wall of the turning chamber and blows air towards the workbench 3.

[0046] When the device needs to turn martensitic stainless steel, the cutting fluid flows into the agglomeration and filtration device 5, thereby driving the air blowing device 6 to work and blowing air onto the workbench 3. When starting to turn martensitic stainless steel, the chips and cutting fluid generated during turning fall into the agglomeration and filtration device 5 under the action of wind force, preventing the chips from being mixed with the cutting fluid and splashing everywhere during the turning process, realizing the agglomeration of the chip-cutting fluid mixture. After the chip-cutting fluid mixture falls into the agglomeration and filtration device 5, the agglomeration and filtration device 5 plays a filtering role to separate the chips and the cutting fluid, thereby realizing the collection and recycling of the chips.

[0047] As an implementation manner of the present invention, the agglomeration and filtration device 5 includes:

[0048] A collection tank 51, the bottom of the collection tank 51 is fixedly connected to the bottom of the turning chamber, and the center of the bottom of the collection tank 51 is rotatably connected to the outer surface of the support seat 4;

[0049] An agglomeration tank 52, the agglomeration tank 52 is located above the collection tank 51, and the front and rear ends of the agglomeration tank 52 are respectively fixedly connected to the side walls of the front and rear ends of the turning chamber;

[0050] An agglomeration funnel 53, the agglomeration funnel 53 is fixedly connected to the top end of the side wall of the filtration tank to agglomerate the chip-cutting fluid mixture;

[0051] A sleeve plate 531, one end of the sleeve plate 531 is fixedly connected to the side wall of the agglomeration funnel 53, and an electric push rod 532 is arranged inside the sleeve plate 531,

[0052] The bottom of the electric push rod 532 is fixedly connected to the side wall of the agglomeration funnel 53 and intermittently moves under the program control of the turning equipment. The top end of the electric push rod 532 is fixedly connected with a baffle plate 533,

[0053] The baffle plate 533 is located inside the sleeve plate 531 and is slidably connected to the inner wall of the sleeve plate 531. When the sleeve plate 531 is pushed out, the top end of the sleeve plate 531 contacts the support seat 4;

[0054] A filter plate 54, the filter plate 54 is located inside the agglomeration funnel 53, the outer wall of the filter plate 54 is fixedly connected to the side wall of the agglomeration funnel 53, and the inner wall of the filter plate 54 is rotatably connected to the support seat 4.

[0055] Before turning martensitic stainless steel, the electric push rod 532 inside the sleeve plate 531 first pushes out the baffle plate 533, thereby dividing the agglomeration funnel 53 into two upper and lower separated parts;

[0056] When the turning equipment starts to work and turns the martensitic stainless steel, the chip cutting fluid mixture is gathered under the action of the gathering funnel 53 to prevent the chip cutting fluid mixture from splashing everywhere. Before falling into the gathering tank 52, the chip cutting fluid mixture passes through the filter plate 54. Under the filtration of the filter plate 54, the chips are blocked.

[0057] When starting to turn, the cutting fluid flows into the gathering funnel 53 and accumulates. After a period of time, the electric push rod 532 drives the baffle 533 to retract, and the accumulated cutting fluid can then continue to flow downward. Since the cutting fluid has accumulated for a period of time, when passing through the air blowing device 6, it can have sufficient impact force to drive the air blowing device 6 to work, and then the air blowing device 6 can effectively blow air to the workbench 3.

[0058] The cutting fluid falls into the gathering tank 52 under the action of gravity, separating the chips from the cutting fluid, realizing the collection and recycling of the chips; and the cutting fluid separated from the chips finally falls into the collection tank 51, realizing the recycling of the cutting fluid, enabling the cutting fluid to be reused, thereby reducing costs.

[0059] The air blowing device 6 includes:

[0060] An impeller 61, the impeller 61 is located inside the gathering tank 52 near the inner wall of the turning chamber, and the impeller shaft of the impeller 61 penetrates the side wall of the gathering tank 52.

[0061] A transmission rod 62, the bottom of the transmission rod 62 is fixed on the upper end surface of the side wall of the collection tank 51 near the inner wall of the turning chamber through cooperation with a bearing, and is cooperated with the impeller shaft of the impeller 61 through a bevel gear engagement.

[0062] A cam 63, the cam 63 is fixedly connected to the outer surface of the top end of the transmission rod 62.

[0063] An airbag 64, the airbag 64 is fixedly connected to the inner wall of the turning chamber, and the airbag 64 is provided with a blowing port 65, and the height of the blowing port 65 is higher than that of the gathering funnel 53, and is used for blowing air to the workbench 3.

[0064] When the cutting fluid falls into the gathering tank 52 through the filter plate 54, the cutting fluid will wash the impeller 61. The impeller 61 starts to rotate under the action of the cutting fluid, and the impeller shaft also starts to rotate accordingly. Since the impeller shaft is cooperated with the transmission rod 62 through a bevel gear engagement, the transmission rod 62 starts to rotate, thereby driving the cam 63 fixedly connected to the outer surface of the top end of the transmission rod 62 to start rotating. While rotating, the cam 63 will continuously squeeze the airbag 64, and the gas in the airbag 64 blows air to the workbench 3 through the blowing port 65, blowing the chip cutting fluid mixture scattered on the surface of the workbench 3 and splashing everywhere into the gathering funnel 53, thereby realizing the gathering of chips.

[0065] During the air blowing process, since the air blowing force of the airbag 64 is relatively small, the chips slide along the upper surface of the workbench 3 and fall into the collecting funnel 63, rather than falling outside the collecting funnel 63.

[0066] As an embodiment of the present invention, the lower end surface of the collecting funnel 53 is behind the impeller 61.

[0067] If the lower end surface of the collecting funnel 53 is in front of the impeller 61, it will cause the cutting fluid to be unable to wash the impeller 61 when passing through the filter plate 54 and entering the collecting tank 52, resulting in the impeller 61 being unable to rotate, the air blowing device 6 being unable to work, and being unable to blow air to the workbench 3, thus reducing the collection efficiency.

[0068] As an embodiment of the present invention, the material of the impeller 61 is martensitic steel.

[0069] Since the present invention is for turning martensitic stainless steel, and martensitic stainless steel has a relatively high tensile strength, with its maximum strength reaching 1600 MPa, which is the steel type with the highest strength level among commercial high-strength steel plates, and the smaller chips are sharper. Therefore, in order to prevent the surface of the impeller 61 from being scratched by the impact of the small chips remaining in the cutting fluid, the material of the impeller 61 is also set as martensitic steel.

[0070] As an embodiment of the present invention, a filter screen 521 is provided in the collecting tank 52. The filter screen 521 is located below the impeller 61, and the aperture of the filter screen 521 is smaller than the aperture of the filter holes on the filter plate 54.

[0071] By setting the filter screen 521, the small-volume chips remaining in the cutting fluid can be blocked, further collecting and recycling the chips, and at the same time enabling the cutting fluid to be further separated from the chips, avoiding the cutting fluid still having chips remaining during secondary recycling.

[0072] As an embodiment of the present invention, the material of the filter screen 521 is natural magnet.

[0073] Since martensitic stainless steel has magnetism and its chips also have magnetism, when the cutting fluid passes through the filter screen 521, since the filter screen 521 is made of natural magnet material, such as Fe3O4, the filter screen 521 can adsorb the chips that cannot be filtered in the cutting fluid, further improving the collection and recycling effect of the chips.

[0074] As an embodiment of the present invention, the material of the airbag 64 is wear-resistant rubber.

[0075] Since the surface of the airbag 64 is squeezed by the cam 63, a certain amount of frictional force will be generated during the squeezing process. In order to prevent the surface of the airbag 64 from being scraped thin by the cam 63 at the contact with the cam during long-term use, resulting in the rupture of the airbag 64, the material of the airbag 64 is set as wear-resistant rubber, thereby improving the service life of the airbag.

[0076] As an embodiment of the present invention, the sleeve plate 531 is inclined.

[0077] By inclining the sleeve plate 531, the cutting fluid is prevented from remaining on the sleeve plate 531.

[0078] As an embodiment of the present invention, a chip-breaking groove is provided on the tool rest 2

[0079] By providing a chip-breaking groove on the tool rest 2, the chips can be broken better, avoiding the problem that the continuous chips squeeze the machined surface, while generating an adhesion phenomenon and forming a built-up edge, which not only aggravates the tool wear, but also causes the machined surface to deteriorate due to tearing.

[0080] Working principle: When the turning equipment starts to work and turns the martensitic stainless steel, the chip-cutting fluid mixture is gathered under the action of the gathering funnel 53 to prevent the chip-cutting fluid mixture from splashing everywhere. After falling into the gathering groove 52, the chip-cutting fluid mixture passes through the filter plate 54. Under the filtration of the filter plate 54, the chips are blocked, and the cutting fluid falls into the gathering groove 52 under the action of gravity, separating the chips from the cutting fluid, realizing the collection and recycling of the chips;

[0081] When the cutting fluid falls into the gathering groove 52 through the filter plate 54, the cutting fluid will wash the impeller 61. The impeller 61 starts to rotate under the action of the cutting fluid, and the impeller 61 shaft also starts to rotate accordingly. Since the impeller 61 shaft is engaged with the transmission rod 62 through bevel gears, the transmission rod 62 starts to rotate, thereby driving the cam 63 fixedly connected to the outer surface of the top end of the transmission rod 62 to start rotating. While rotating, the cam 63 will continuously squeeze the airbag 64, and the gas in the airbag 64 blows air to the workbench 3 through the air blowing port 65, blowing the chip-cutting fluid mixture scattered on the surface of the workbench 3 and splashing everywhere into the gathering funnel 53, thereby realizing the gathering of the chips;

[0082] And during the air blowing process, since the air blowing force of the airbag 64 is small, the chips slide along the upper surface of the workbench 3 and fall into the gathering funnel 63, rather than falling outside the gathering funnel 63;

[0083] The cutting fluid separated from the chips finally falls into the collection tank 51, realizing the recycling of the cutting fluid, enabling the cutting fluid to be reused, thereby reducing costs.

[0084] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not exist, the above-described embodiments only express several implementation manners of the present invention. Its description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the invention patent; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention; therefore, the protection scope of the present invention patent should be subject to the appended claims.
