Description
Technical Field
[0001] This utility model relates to the field of stamping equipment technology, and in particular to a double-sided oiling device. Background Technology
[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to sheet metal or other materials at room temperature, causing them to separate or undergo plastic deformation to obtain the desired parts. Before stamping sheet metal or other materials, oil lubrication is required. The oil forms a lubricating film between the die and the material, reducing friction, lowering stress, and also providing some cooling.
[0003] In existing technologies, the oiling process before stamping is done manually, with workers using brushes, rollers, or other application tools to apply oil to the material surface. This manual oiling method is inefficient, cannot effectively match the subsequent stamping cycle, and cannot effectively control the amount of oil used, easily leading to waste due to excessive application or affecting stamping due to insufficient application. Utility Model Content
[0004] To address the aforementioned issues, this application provides a reasonably structured double-sided oiling device, which replaces manual oiling with automatic oiling, effectively improving efficiency. It can also be connected in series with automated production lines to match the stamping cycle and effectively ensure the consistency of the double-sided oiling effect.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A double-sided oiling device includes columns spaced apart on a work platform. A downward drive assembly is installed between the columns via a support plate, and a sponge block is installed at the lower end of the downward drive assembly. An oil supply assembly is installed on the work platform directly below the sponge block, supported by a support rod. The oil supply assembly includes an oiling plate and a connecting plate fitted together vertically. An oil storage space is formed between the oiling plate and the connecting plate. The oil storage space is connected to an external oil supply device via a pipeline. An oil outlet is provided on the oiling plate, which is connected to the oil storage space below.
[0007] As a further improvement to the above technical solution:
[0008] The top surface of the oiling plate has multiple concave oil collection grooves from the inside to the outside. The top surface of the oiling plate located inside and outside each oil collection groove forms an oil outlet groove. The bottom of the oil outlet groove is provided with multiple oil outlet holes spaced apart along the length direction. It also includes an oil drop structure connected to each oil collection groove, through which the oil in the oil collection groove falls.
[0009] The depth of the oil collection trough is greater than the depth of the oil outlet trough; guide blocks are installed circumferentially on the top surface of the oil coating plate located outside the outermost oil outlet trough, and the inner side of the guide block is a downward and inward inclined surface.
[0010] The top surface of the oiling plate located inside the innermost oil outlet groove is recessed to form a recessed structure. A through hole 1 is opened at the center of the recessed structure, and a through hole 2 is opened on the adapter plate, which is directly opposite to the through hole 1. A groove 1 is opened inward from the opposite edge of the oiling plate, and a groove 2 is opened on the adapter plate, which is directly opposite to the groove 1. The oil collection groove is connected to the groove 1 or the recessed structure to form an oil discharge structure.
[0011] The oil collecting groove is connected to the groove opening at both ends, or the oil collecting groove is connected to the groove opening or the recessed structure via a radial through groove.
[0012] The top surface of the adapter plate is recessed to form an oil storage space, and an oil inlet hole is opened on the bottom surface of the oil storage space. The end of the pipeline connected to the external oil supply equipment is installed at the oil inlet hole. The top surfaces of the adapter plate located inside the inner edge and outside the outer edge of the oil storage space are recessed to form an inner sealing groove and an outer sealing groove, respectively. Sealing rings are installed in the inner sealing groove and the outer sealing groove, and the sealing rings are pressed between the oiling plate and the adapter plate.
[0013] An oil receiving box is installed in the middle of the support rod below the oil supply assembly to receive the oil falling from the oil supply assembly.
[0014] The lower end of the downdrive assembly is equipped with a lifting seat, and a sponge block is installed on the bottom surface of the lifting seat via a sponge seat; a central hole is opened in the middle of the sponge block, and one or more sets of material removal components are installed on the sponge seat located at the central hole of the sponge block.
[0015] The downward drive assembly is a pen-shaped cylinder mounted on the support plate with its output end facing downward. A support is mounted on the upper end of the pen-shaped cylinder, and guide rods are movably mounted on both sides of the pen-shaped cylinder, passing through the support plate. The top and bottom ends of the guide rods are respectively mounted on the support and the lifting seat.
[0016] The structure of a single stripping assembly is as follows: a bushing is installed on the sponge seat, a push rod is movably installed through the bushing, an end block extends outward from the bottom end of the push rod, a flexible element is installed on the end face of the end block, and an end cap is installed on the top end of the push rod extending upward from the bushing; an elastic element is fitted on the push rod located between the bushing and the end block.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] When this utility model is used, the downward drive component drives the sponge block to descend and absorb oil. After the product is placed on the oil supply component, the sponge block descends again. The sponge block, together with the oil supply component, achieves oiling on both sides of the product. Thus, automatic oiling replaces manual oiling, effectively improving efficiency. It can also be connected to an automated production line to match the stamping cycle and effectively ensure the consistency of the oiling effect on both sides.
[0019] This utility model also has the following advantages:
[0020] The oil in the oil storage space flows through the oil outlet hole to the oil outlet groove on the top surface of the oiling plate. Excess oil in the oil outlet groove will flow smoothly through the oil collection groove to the oil drop structure and fall down, thereby effectively ensuring the uniformity and consistency of oiling the bottom surface of the product placed on the oiling plate.
[0021] The inner side of the sponge block is equipped with a stripping component. After the downward drive component drives the sponge block to move downward and apply oil to the top surface of the product, the stripping component will apply force to the top surface of the product to facilitate the smooth separation of the top surface of the product from the sponge block, effectively ensuring the continuous operation of automated oiling.

[0033] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0034] like Figure 1 and Figure 2 As shown, a double-sided oiling device in this embodiment includes columns 10 spaced apart on a work platform 30. A downward drive assembly 1 is installed between the columns 10 via a support plate 2. A sponge block 4 is installed at the lower end of the downward drive assembly 1. An oil supply assembly 5 is installed on the work platform 30 directly below the sponge block 4, supported by a support rod 6. The oil supply assembly 5 includes an oiling plate 51 and a connecting plate 53 fitted together. An oil storage space 531 is formed between the oiling plate 51 and the connecting plate 53. The oil storage space 531 is connected to an external oil supply device via a pipeline. An oil outlet hole 514 is provided on the oiling plate 51, which is connected to the lower oil storage space 531.
[0035] In this embodiment, during use, the downward drive component 1 drives the sponge block 4 downward to absorb oil. After the product 20 is placed on the oil supply component 5, the sponge block 4 moves downward again. The sponge block 4, in conjunction with the oil supply component 5, achieves double-sided oiling of the product 20, thereby replacing manual oiling with automatic oiling for double-sided oiling.
[0036] In practical use, the double-sided oiling device of this embodiment can be installed on the existing press. The downward drive component 1 is installed between the two columns 10 of the press via the support plate 2. The bottom end of the support rod 6 supporting the oil supply component 5 is installed on the base plate 8. The base plate 8 is fixedly installed on the working platform 30 of the press, so that the double-sided oiling device and the press can be connected in a convenient and quick manner and the operation can be fully automated.
[0037] like Figure 3 and Figure 5 As shown, the top surface of the oiling plate 51 has multiple concave oil collection grooves 512 from the inside to the outside. The top surface of the oiling plate 51 located inside and outside each oil collection groove 512 is concave to form an oil outlet groove 511. The bottom of the oil outlet groove 511 is provided with multiple oil outlet holes 514 spaced apart along the length direction. It also includes an oil drop structure connected to each oil collection groove 512, through which the oil in the oil collection groove 512 falls.
[0038] In this embodiment, the oil in the oil storage space 531 flows through the oil outlet hole 514 to the oil outlet groove 511 on the top surface of the oiling plate 51. The excess oil in the oil outlet groove 511 will flow smoothly through the oil collection groove 512 to the oil drop structure and fall down, thereby effectively ensuring the uniformity and consistency of the oiling of the bottom surface of the product 20 placed on the oiling plate 51.
[0039] The depth of the oil collection trough 512 is greater than the depth of the oil outlet trough 511, thus effectively ensuring the rapid and smooth collection of excess oil. The top surface of the oiling plate 51 located outside the outermost oil outlet trough 511 is equipped with guide blocks 52 at intervals along the circumference. The inner side of the guide block 52 is a downward and inward inclined surface.
[0040] In this embodiment, by setting the guide block 52 and its upper inclined surface, the product 20 can be quickly placed and positioned on the oil supply component 5, and the product 20 can be circumferentially limited during oiling.
[0041] like Figure 3 and Figure 4 As shown, the top surface of the oiling plate 51 located inside the innermost oil outlet groove 511 is recessed to form a recessed structure 517. A through hole 515 is provided at the center of the recessed structure 517, and a through hole 534 is provided on the adapter plate 53, which is directly opposite to the through hole 515. A groove 513 is provided inward from the opposite edge of the oiling plate 51, and a groove 533 is provided on the adapter plate 53, which is directly opposite to the groove 513. The oil collection groove 512 is connected to the groove 513 or the recessed structure 517 to form an oil discharge structure.
[0042] In this embodiment, the recessed structure 517 and the slot 513 form an oil-falling structure on the inner and outer sides of the oiling plate 51, respectively, which is connected to the adjacent oil collection tank 512. The overall structure is simplified, which helps to ensure the smooth fall of oil in the oil collection tank 512.
[0043] The two ends of the oil collecting groove 512 are connected to the groove opening 513, or the oil collecting groove 512 is connected to the groove opening 513 or the recessed structure 517 via the radial through groove 516, which effectively ensures that the oil in the oil collecting groove 512 falls quickly and smoothly.
[0044] The top surface of the adapter plate 53 is recessed to form an oil storage space 531. An oil inlet hole 536 is provided on the bottom surface of the oil storage space 531. The end of the pipeline connected to the external oil supply equipment is installed at the oil inlet hole 536, and the external oil supply equipment supplies oil into the oil storage space 531 through the oil inlet hole 536. The top surface of the adapter plate 53, located inside the inner edge and outside the outer edge of the oil storage space 531, is recessed to form an inner sealing groove 535 and an outer sealing groove 532, respectively. Sealing rings are installed in the inner sealing groove 535 and the outer sealing groove 532, respectively. The sealing rings are pressed between the oil coating plate 51 and the adapter plate 53, thereby achieving a circumferential seal between the oil coating plate 51 and the adapter plate 53 at the edge of the oil storage space 531. This effectively prevents or even avoids oil leakage at the interface between the oil coating plate 51 and the adapter plate 53, and effectively ensures that the oil storage space 531 supplies oil to the top surface of the oil coating plate 51 through the oil outlet hole 514.
[0045] An oil receiving box 7 is installed in the middle of the support rod 6 located below the oil supply assembly 5, and the oil receiving box 7 receives the oil falling from the oil supply assembly 5.
[0046] In this embodiment, the oil collection box 7 can be connected to an external oil supply device via a pipeline according to actual needs, so as to realize the effective use of oil. Of course, the oil in the oil collection box 7 can also be used for other purposes or treated in other ways.
[0047] A lifting seat 3 is installed at the lower end of the downlink drive assembly 1. A sponge block 4 is installed on the bottom surface of the lifting seat 3 via a sponge seat 41. A central hole is opened in the middle of the sponge block 4. One or more sets of material removal assemblies 9 are installed on the sponge seat 41 located at the central hole of the sponge block 4. Figure 6 As shown.
[0048] In this embodiment, a stripping component 9 is provided on the inner side of the sponge block 4. After the downward drive component 1 drives the sponge block 4 downward to apply oil to the top surface of the product 20, the stripping component 9 will apply force to the top surface of the product 20 to facilitate the smooth separation of the top surface of the product 20 from the sponge block 4, effectively ensuring the continuous operation of automated oiling.
[0049] In this embodiment, a reinforcing plate 90 is fitted to the bottom surface of the sponge seat 41 located at the center of the sponge block 4. The reinforcing plate 90 can be locked to the lifting seat 3 above the sponge seat 41 by bolts.
[0050] The downward drive assembly 1 is a pen-shaped cylinder mounted on the support plate 2 with the output end facing downward. A support 12 is mounted on the upper end of the pen-shaped cylinder. Guide rods 11 are movably mounted on both sides of the pen-shaped cylinder, passing through the support plate 2. The top and bottom ends of the guide rods 11 are respectively mounted on the support 12 and the lifting seat 3.
[0051] In this embodiment, the lifting seat 3 is driven to move up and down by the action of the pen-shaped cylinder, and the guide rod 11 guides the up and down movement.
[0052] like Figure 7 As shown, the structure of the single-unit unloading assembly 9 is as follows: it includes a bushing 94 installed on the sponge seat 41, a push rod 92 movably installed through the bushing 94, an end block extending outward from the bottom end of the push rod 92, a flexible element 91 installed on the end face of the end block, and an end cap 95 installed on the top end of the push rod 92 extending upward from the bushing 94; an elastic element 93 is fitted on the push rod 92 located between the bushing 94 and the end block.
[0053] During use, as the sponge block 4 moves downward and presses down onto the top surface of the product 20, the bottom surface of the flexible element 91 abuts against the top surface of the product 20, and the push rod 92 is subjected to force relative to the bushing 94 and the sponge seat 41, causing the elastic element 93 to compress. When the sponge block 4 moves upward and is about to detach from the product 20, the compressed elastic element 93 drives the push rod 92 to return to its original position relative to the downward movement, thereby applying downward force to the product 20 through the flexible element 91, so that the product 20 can smoothly detach from the sponge block 4.
[0054] The double-sided oiling device of this invention can be connected in series with existing presses for fully automated operation.
[0055] The method of using this utility model is as follows:
[0056] The downward drive component 1 drives the sponge block 4 downward. The sponge block 4 adheres to the top surface of the oiling plate 51 of the oil supply component 5, causing the bottom surface of the sponge block 4 to absorb oil. Then, the downward drive component 1 drives the sponge block 4 upward to a preset height. The external transfer mechanism transfers the product 20 onto the oiling plate 51 of the oil supply component 5. The sponge block 4 moves downward again, so that the sponge block 4 cooperates with the oil supply component 5 to apply oil to the top surface of the product 20. During this process, the external oil supply device supplies oil to the oil storage space 531 of the oil supply component 5 through the oil inlet 536. The oil in the oil storage space 531 rises to the top surface of the oiling plate 51 through the oil outlet 514, realizing the oil supply during double-sided oiling. The excess oil on the top surface of the oiling plate 51 will be collected in the oil collection tank 512 and fall quickly and smoothly into the lower oil receiving box 7 through the slot 1 513, slot 2 533 or through hole 1 515, through hole 2 534.
[0057] This invention enables automatic oiling to replace manual oiling, effectively improving efficiency. It can also be integrated into automated production lines to match the stamping cycle and effectively ensure the consistency of oiling effect on both sides.
[0058] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
