A space for accommodating the liquid lubricating oil is provided on the sidewalls of the guide rails, and this space communicates with the oil-sealing chambers. When the oil-sealing chambers move along the guide rails, the liquid lubricating oil flows through the holes at both ends in the space on the sidewalls of the guide rails and inside the oil-sealing chambers.

[0013] Preferably, the sealing block is located between the plurality of through holes at both ends, and the displacement stroke of the sealing tank will not cause the sealing block to extend beyond the range between the through holes at both ends.

Detailed Implementation

[0032] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] Example 1, as shown in Figures 1-8, a spring processing bending device according to an embodiment of this application includes a first device part 1, a second device part 2, and a plurality of bending power mechanisms 3 evenly distributed circumferentially on the second device part 2. The first device part 1 is used to control the operation of the entire bending device and to feed the steel wire required for processing the spring to the second device part 2. The second device part 2 is used to control the axial rotation of the steel wire and its specific axial displacement. The bending power mechanism 3 is arranged radially along the second device part 2.

[0035] As shown in Figures 1 and 2, in a specific embodiment of this application, the first equipment unit 1 includes a protective cover 11, inside which a wire feeding shaft and a wire rotating shaft are provided to complete the position change of the steel wire used to process the spring. It also includes a machine base 12 and a control component 13 provided on the machine base 12. It is understood that the equipment inside the protective cover 11 and the control component 13 are all prior art, and will not be described in detail here.

[0036] The second equipment section 2 includes a mounting platform 21 fixed above the machine base 12 and at the end of the protective cover 11. An axial moving shaft 22 and a rotating core shaft 23 are provided at the axis of the mounting platform 21 and are adapted to the wire feeding shaft and rotating core shaft provided inside the protective cover 11.

[0037] As shown in Figures 1-3, the bending power mechanism 3 includes a mounting plate 31 fixed to the end face of the second equipment section 2, a mounting block 32 with radial displacement, and a power member 34 that provides radial displacement power; wherein, a connecting plate 33 is fixedly connected to one end of the mounting block 32, and a power member 34 is fixedly connected to one end of the mounting plate 31. A swing arm 35 is keyed to the output end of the power member 34, and a connecting shaft 36 is hinged to the swing arm 35. The connecting shaft 36 and the connecting plate 33 are hinged together.

[0038] It is understandable that the power component 34 drives the swing arm 35 to rotate, which will cause the mounting block 32 to move radially back and forth through the connecting shaft 36.

[0039] It should be noted that the power component 34 can be a servo motor in the prior art, and the output end of the swing arm 35 and the power component 34 can be connected by a multi-position eccentric connection to meet the different displacement strokes of the mounting block 32 in actual use.

[0040] Specifically, as shown in Figures 3-8, a guide mechanism 4 is provided between the mounting plate 31 and the mounting block 32. The guide mechanism 4 includes two guide rails 41, two oil sealing chambers 42, four storage chambers 43, four end caps 44, and two pressure applying components 45. The two guide rails 41 are fixedly connected to the mounting plate 31 in parallel. The two oil sealing chambers 42 are respectively sealed and slid on the two guide rails 41 and fixedly connected to the mounting block 32. The four storage chambers 43 are respectively sealed and connected to the two ends of the two oil sealing chambers 42. The four end caps 44 are respectively sealed and connected to the four storage chambers 32. At the end of the chamber 43, two pressure-applying components 45 are respectively fixed to two guide rails 41 and slidably inserted into two oil-sealing chambers 42. The oil-sealing chambers 42 are filled with liquid lubricating oil. Holes are provided at both ends of the oil-sealing chambers 42 facing the side walls of the guide rails 41. Spaces for accommodating liquid lubricating oil are provided on the side walls of the guide rails 41. These spaces are connected to the oil-sealing chambers 42. When the oil-sealing chambers 42 move along the guide rails 41, the liquid lubricating oil flows through the holes at both ends in the space on the side walls of the guide rails 41 and inside the oil-sealing chambers 42.

[0041] Specifically, as shown in Figure 8, the space on the side wall of the guide rail 41 for accommodating liquid lubricating oil is a groove 411 arranged along its own length. There are protrusions on both sides of the groove 411, and sealing strips 412 are respectively installed on the side walls of the protrusions. The oil sealing chamber 42, the storage chamber 43 and the end 44 are respectively in a sealing sliding fit with the protrusions of the groove 411.

[0042] As shown in Figure 7, the holes in the inner wall of the oil sealing chamber 42 are through holes 421, and multiple through holes 421 connect the groove 411 and the oil sealing chamber 42.

[0043] It is understandable that the oil sealing chamber 42 is arranged in a U-shape. When it slides in cooperation with the protruding seal, it will form three independent chambers between the oil sealing chamber 42 and the groove 411. As shown in Figure 7, the presence of multiple through holes 421 on it will allow the three independent chambers to communicate with each other through the oil sealing chamber 42.

[0044] Furthermore, a plurality of fitting grooves 422 are provided on the side of the through hole 421 facing the end of the oil sealing chamber 42. The fitting grooves 422 do not penetrate the inner wall of the oil sealing chamber 42, and a sealing block 423 is correspondingly fitted into the fitting groove 422.

[0045] Among them, the sealing block 423 has a pressure-applying recess 424 on the side facing the through hole 421.

[0046] It is understandable that the presence of sealing block 423 will cause the groove 411 to form a chamber with both ends sealed under the action of the two sealing blocks 423. Thus, it is further understood that at this time, the multiple grooves 411, under the action of sealing block 423, form a complete closed space with the oil sealing chamber 42, the storage chamber 43 and the end 44.

[0047] It can be further understood that the pressure-applying recess 424 can, under the pressure of the liquid lubricating oil, enable the sealing block 423 to maintain better sealing performance (its sidewall will have a better sealing effect with the outer wall contact surface under pressure).

[0048] Furthermore, as shown in Figure 10, a second sealing block 435 is provided between the storage compartment 43 and the groove 411. The second sealing block 435 is fixed to the storage compartment 43 and slides in the groove 411 in a sealing manner.

[0049] Understandably, the design of sealing block 2 435 is intended to ensure the independence of the aforementioned enclosed space even if sealing block 1 423 leaks.

[0050] As shown in Figure 5, one of the two ends 44 on the same guide rail 41 is equipped with two solenoid valves 441. One solenoid valve 441 is used to input liquid lubricating oil, and the other solenoid valve 441 is used to output liquid lubricating oil.

[0051] It is understandable that liquid lubricating oil can be injected into the enclosed space through one of the solenoid valves 441, while the flow rate can be controlled at the other solenoid valve 441 to expel the air in the original enclosed space and control the pressure of the liquid lubricating oil in the enclosed space, which also facilitates the subsequent replacement and maintenance of the liquid lubricating oil.

[0052] As shown in Figures 5 and 6, the pressure application component 45 includes a positioning plate 451, two connecting rods 452 and a sealing block 453. The positioning plate 451 is fixed to one end of the guide rail 41. The two connecting rods 452 are respectively fixed to the positioning plate 451 in parallel and are slidably inserted into the end 44 and then extend to the oil sealing chamber 42. The sealing block 453 is slidably sealed in the oil sealing chamber 42 and fixed to the two connecting rods 452.

[0053] It should be noted that the sealing block 453 is located between the multiple through holes 421 at both ends, and the displacement stroke of the oil sealing tank 42 will not cause the sealing block 453 to exceed the range between the through holes 421 at both ends.

[0054] Therefore, it can be understood that in the initial stage of use, a certain pressure of liquid lubricating oil is injected into the closed space formed by the groove 411, the oil sealing chamber 42, the storage chamber 43, and the end 44, ensuring that the sealing block 453 is located between the through holes 421 at both ends (it should be noted that the subsequent stroke of the oil sealing chamber 42 will not cause the sealing block 453 to exceed the range between the through holes 421 at both ends). Then, the fixture required for bending is installed on the mounting block 32. The output of the steel wire is controlled by the axial movement shaft 22 and the rotating mandrel 23, and the corresponding power component 34 is started according to the program, so that the corresponding mounting block 32 carries the bending fixture and moves along the guide rail 41 to bend and deform the steel wire, and then process it into the required spring. During this process, the oil sealing chamber... 42 will undergo a corresponding displacement on the guide rail 41. Since the sealing block 453 is fixed to the positioning plate 451 under the action of the connecting rod 452, and the positioning plate 451 is fixed to the guide rail 41, when the sealing oil chamber 42 moves along the guide rail 41, the sealing block 453 will change position inside the sealing oil chamber 42. This application takes the displacement of the sealing block 453 relative to the sealing oil chamber 42 as an example (i.e., assuming the sealing oil chamber 42 is stationary while the sealing block 453 moves for demonstration). When the sealing block 453 moves towards the through hole 421 at the end where the solenoid valve 441 is installed, the liquid lubricating oil on the side of the sealing block 453 facing the solenoid valve 441 will be squeezed and flow into the groove 411 through the through hole 421 on that side. Similarly, the liquid lubricating oil originally in the groove 411 will be squeezed through the through hole 421 on the other side and enter the oil sealing chamber 42 at the end away from the solenoid valve 441. Conversely, when the sealing block 453 moves towards the end without the solenoid valve 441, the liquid lubricating oil here will flow into the groove 411 through the through hole 421 on that side, and enter the oil sealing chamber 42 at the end near the solenoid valve 441 through the through hole 421 on the other side. During this process, the liquid lubricating oil flows in the closed space with the displacement of the oil sealing chamber 42. The flowing liquid lubricating oil fully lubricates the oil sealing chamber 42 and the guide rail 41. Moreover, the design of the groove 411 reduces the rigid contact area between the oil sealing chamber 42 and the guide rail 41, which, in conjunction with... The flowing liquid lubricating oil reduces wear caused by friction between the sealing chamber 42 and the guide rail 41. In addition, the liquid lubricating oil with a certain pressure can ensure the stability between the sealing chamber 42 and the guide rail 41 to a certain extent. At the same time, the flowing lubricating oil can also carry away the debris generated by wear during long-term use. During the flow, the debris will be settled and collected in one of the collection chambers 43 at both ends (depending on its position). It can be understood that the liquid lubricating oil fluctuates more in the range between the through holes 421 at both ends during the flow, while the fluctuation is relatively smaller in the collection chambers 43 at both ends. Therefore, the debris can settle in the collection chamber 43, so that the debris can be discharged when the liquid lubricating oil is replaced later.

[0055] In related technologies, this spring processing bending device requires strong sealing between the sealing oil chamber 42 and the guide rail 41 during the processing because the oil sealing chamber 42 and the guide rail 41 will frequently shift. If the seal between the two fails, it will affect the flow of the liquid lubricating oil, causing the liquid lubricating oil to carry debris to the collection chambers 43 at both ends, which will in turn affect the service life of the oil sealing chamber 42 and the guide rail 41.

[0056] According to some embodiments of this application, as shown in FIG9, a compensation mechanism 5 is provided on the sealing block 453. The compensation mechanism 5 includes an incline seal 51 embedded on the outside of the sealing block 453.

[0057] It should be noted that, in the specific embodiments of this application, the U-shaped seal 51 can be made of rubber to ensure that it has a certain deformation capability.

[0058] The C-shaped seal 51 and the oil sealing chamber 42 are in a sliding seal fit, and the inner side of the C-shaped seal 51 is provided with a C-shaped positioning strip 511.

[0059] Understandably, the design of the positioning strip 511 can enhance the strength of the U-shaped seal 51 and prevent it from deforming significantly when it is deformed, thereby affecting the actual sealing effect.

[0060] Specifically, the outer wall of the sealing block 453 is provided with an installation groove 52 that is adapted to the U-shaped seal 51 and the positioning strip 511. The installation groove 52 is U-shaped in general and has a convex cross section.

[0061] Therefore, the U-shaped seal 51 can be embedded inside the mounting groove 52 to form a sealing embedding effect.

[0062] Furthermore, the sealing block 453 has symmetrically arranged end face recesses 53 at both ends, and multiple through holes 54 communicating with the mounting groove 52 are evenly arranged on the outer side of the end face recesses 53.

[0063] Therefore, it can be understood that when the liquid lubricating oil flows on both sides of the sealing block 453, the liquid lubricating oil is squeezed and its own pressure will seep out through the multiple through holes 54 on both sides of the end face recess 53 and apply pressure to the inner side (non-positioning strip 511) of the incised seal 51 embedded in the mounting groove 52, so that the incised seal 51 has a force to separate from the mounting groove 52, thereby forming a tighter fit between the incised seal 51 and the inner wall of the oil sealing chamber 42. This will improve the sealing performance between the sealing block 453 and the oil sealing chamber 42. Even if the incised seal 51 has a certain wear, its own deformation will ensure the sealing performance between the sealing block 453 and the oil sealing chamber 42.

[0064] In related technologies, this spring processing bending device has a housing chamber 43 symmetrically arranged at both ends of the oil sealing chamber 42. Impurities carried by the liquid lubricating oil due to its flow will settle into the housing chamber 43 on the lower side under the action of gravity. This design will cause impurities in the liquid lubricating oil on the other side to require multiple flows of lubricating oil before they can settle into the housing chamber 43 on the lower side. During this process, impurities will cause certain damage to the oil sealing chamber 42 and the guide rail 41, affecting their service life.

[0065] In embodiment 3, according to some embodiments of this application, as shown in Figures 10 and 1, a storage cavity 431 is provided inside the storage compartment 43, and an anti-backflow nozzle 432 is sealed and embedded at one end of the storage cavity 431 that connects with the oil sealing compartment 42.

[0066] Among them, the anti-backflow nozzle 432 is made of rubber and has a U-shaped connecting port 433. The end of the connecting port 433 facing the oil sealing chamber 42 is open, and the end of the connecting port 433 facing the receiving cavity 431 is closed.

[0067] Specifically, a fixing strip 434 is fixedly connected to the periphery of the anti-backflow nozzle 432, and the fixing strip 434 is fixedly connected to the inner wall of the receiving cavity 431.

[0068] Therefore, it can be understood that regardless of whether the collection chamber 43 is located at a high or low position, impurities carried by the liquid lubricating oil during its flow will enter the collection chambers 43 on both sides due to the fluidity of the liquid lubricating oil. Under the gradual change of the connection port 433 on the anti-backflow nozzle 432, most of the impurities in the liquid lubricating oil that enter the collection chamber 43 will be blocked and will no longer flow out of the collection chamber 43 with the liquid lubricating oil. In this way, the impurity content in the lubricating oil will be greatly reduced, and the impurities (debris) will be better collected and settled, which will facilitate the later maintenance work. It should be noted that solenoid valves 441 can be installed on both collection chambers 43 to facilitate better replacement of lubricating oil and better discharge of the collected debris.

[0069] It should be noted that the specific models and specifications of the control component 13, axial moving shaft 22, rotating core shaft 23, power component 34, sealing strip 412 and solenoid valve 441 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0070] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
