Description

Technical Field

[0001] The invention relates to the technical field of deep drawing, spinning and diameter expansion, and in particular to a high-precision metal deep drawing and spinning device based on a novel transfer die technology. Background Art

[0002] Drawing and spinning is a metal forming process, which is to fix a metal sheet or hollow blank on a rotating core mold, and apply pressure to the blank through a spinning wheel (or spinning tool) to make the blank gradually fit the shape of the core mold and produce plastic deformation. During the drawing and spinning process, the main deformation mode of the blank is stretching and thinning. Drawing and spinning is suitable for a variety of processing methods, including drawing and spinning expansion.

[0003] The diameter expansion by deep drawing and spinning is mainly achieved by applying pressure to the inner wall of the rotating cylindrical metal blank through the spinning tool, causing the inner wall of the cylinder to continuously produce local plastic deformation, thereby achieving the purpose of diameter expansion. In this process, the blank is tightly fixed on the core mold of the spinning machine, and the spinning wheel acts on the surface according to a certain trajectory and pressure. For example, the cylindrical blank is fixed on the core mold, and the spinning wheel is gradually squeezed along the inner wall of the cylinder to expand the edge of the thin plate outward, just like turning a small-diameter cylinder into a large-diameter cylinder in this way.

[0004] Although the existing deep drawing and spinning devices can effectively expand the diameter of the blank, the following problems still exist: the deep drawing and spinning expansion process is repeated for many times on the inner wall. After the spinning wheel spins the inner wall of the blank for the first time, the staff needs to manually clean the waste generated during the spinning process of the inner wall of the blank, and each spinning process needs to be cleaned once to ensure the quality of spinning and prevent the residual waste from scratching the inner wall of the blank. Repeated cleaning seriously affects the spinning efficiency.

[0005] Therefore, it is necessary to design a spinning and stretching device so that the spinning wheel can continuously and evenly spray the spinning oil on the inner wall of the blank when spinning on the inner wall of the blank. At the same time, every time the spinning wheel spins the inner wall of the blank, the waste material on the inner wall can be directly cleaned during the process of the spinning wheel moving out from the inner wall of the blank, without the need for manual cleaning multiple times, thereby effectively improving the quality and efficiency of spinning. Summary of the invention

[0006] In view of the problems in the existing technology that spinning oil cannot be continuously and evenly sprayed on the inner wall of the blank and the waste material in the inner wall of the blank needs to be manually cleaned after each spinning, which affects the spinning quality and efficiency, a high-precision metal deep drawing and spinning device based on a new transfer die technology is proposed.

[0007] The present application provides a high-precision metal deep drawing and spinning device based on a novel transfer die technology, the purpose of which is: by setting a cleaning component and a control component, when the rotary wheel one spins the inner wall of the blank, the control component tightens the nylon wire in the cleaning component, so that the rotary wheel one spins the inner wall of the blank normally; after the rotary wheel one processes the inner wall of the blank from the outside to the inside once, the rotary wheel one moves from the inside to the outside, and the nylon wire is released by the control component, and the high-speed rotating conduction rod causes the nylon wire to unfold; the rotary wheel one sweeps the waste material generated during one spinning out of the blank during the outward movement, and directly completes the cleaning of the inner wall of the blank without manual intervention, effectively improving the spinning efficiency; at the same time, an oiling component is set in front of the rotary wheel one, so that the oiling component oils the inner wall area of ​​the blank in front before the rotary wheel one spins, ensuring that the inner wall of the blank is coated with spinning oil during the processing of the rotary wheel one, effectively improving the spinning quality.

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] Example 1, reference Figure 1-Figure 4, which is the first embodiment of the present invention, provides a high-precision metal drawing and spinning device based on a new transfer die technology, including a base plate 1, a mounting plate 2 fixedly mounted on the upper end of the base plate 1, a spinning machine 3 fixedly mounted on the mounting plate 2, and also includes an operating unit installed on the spinning machine 3, and the operating unit includes a spinning component and a cleaning component installed on the spinning machine 3.

[0023] The spinning components include a sliding groove 4 opened on the spinning machine table 3, a sliding block 5 slidably installed in the sliding groove 4, an operating table 6 fixedly installed on the sliding block 5, a connecting plate 7 fixedly installed on the operating table 6, a cushion block 8 fixedly installed on the connecting plate 7, a conversion box 9 rotatably installed on the cushion block 8, a fixed plate 10 fixedly installed on the upper end of the conversion box 9, a servo motor 11 fixedly installed on the upper end of the fixed plate 10, a supporting plate 12 and a supporting plate 2 13 fixedly installed on the side wall of the conversion box 9, a rotating rod 14 rotatably installed on the supporting plate 2 13, a rotating wheel 2 15 fixedly installed at one end of the rotating rod 14, and a diameter expansion and drawing component is installed on the supporting plate 12.

[0024] The end face of the sliding groove 4 is trapezoidal, the end face shape and size of the sliding block 5 are the same as the end face shape and size of the sliding groove 4, the conversion box 9 is rotatably mounted on the cushion block 8, the driving end of the servo motor 11 is fixedly connected to the upper end of the conversion box 9, and a clamping assembly is installed on the mounting plate 2.

[0025] Reference Figure 3-Figure 6 The expansion and drawing assembly includes a conducting rod 16 rotatably mounted on a carrier plate 12, a rotary wheel 17 fixedly mounted on the outer wall of the conducting rod 16, and a plurality of drive motors are installed in the conversion box 9, and the plurality of drive motors respectively drive the corresponding rotating rod 14 and the conducting rod 16. The clamping assembly includes a mounting groove provided on the mounting plate 2, an assembly ring 18 rotatably mounted on the mounting groove, a clamping disc 19 rotatably mounted on the inner ring of the assembly ring 18, and a mold cylinder 20 fixedly mounted on the clamping disc 19 for placing the blank.

[0026] Specifically, the driving end of the servo motor 11 is fixedly connected to the conversion box 9, so that the driving end of the servo motor 11 can drive the conversion box 9 to rotate when it rotates. A plurality of spinning tools, such as a rotary wheel 17 and a rotary wheel 15, are installed on the side wall of the conversion box 9. The rotary wheel 17 is used to perform spinning and expansion on the inner wall of the blank, and the rotary wheel 15 is used to perform deep drawing and spinning on the outer walls of different blanks. By adjusting the angle of the conversion box 9 by the servo motor 11, the conversion box 9 can perform different treatments on different blanks through different spinning tools, effectively improving the applicability of the overall device (this is the prior art and will not be elaborated on here). A control component (not shown in the figure) is installed on the spinning machine 3. The control component can control the operating table 6 to move freely in the horizontal direction to meet the position adjustment of the rotary wheel 17 during spinning and expansion (this is the prior art and will not be elaborated on again). The driving motor drives the corresponding rotating rod 14 or the conducting rod 16 to rotate at high speed through a transmission component (not shown in the figure) (this is the prior art and will not be elaborated on again).

[0027] The clamping assembly clamps and fixes one end of the blank through the clamping disk 19 therein. The blank is placed on the inner wall of the mold barrel 20 and fixed by the clamping disk 19. When the assembly ring 18 rotates, the blank is driven to rotate at high speed through the clamping disk 19 to perform the spinning and expanding operation. However, when the rotary wheel 17 performs spinning and expanding on the inner wall of the blank in the mold barrel 20, it is blocked by the barrel wall on all sides, so it is difficult for the staff to spray the spinning oil on the inner wall of the blank at all times. Moreover, when the rotary wheel 17 performs spinning and expanding on the inner wall of the blank, the deformation of the blank is not prevented. Usually, multiple passes are used for the operation, that is, the rotary wheel 17 spins the blank from the outside to the inside. After the rotary wheel 17 completes one pass of operation, the rotary wheel 17 needs to be removed, and the waste on the inner wall of the rotary wheel 17 needs to be manually cleaned to prevent the waste from scratching the inner wall of the blank with the rotary wheel 17 in the second pass. Manual processing is time-consuming and labor-intensive, which seriously affects the quality and efficiency of the billet spinning expansion. For the above problems, the specific solutions are referred to the following embodiments.

[0028] Example 2, reference Figure 4-Figure 7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning component includes a sliding sleeve 21 slidably mounted on the outer wall of the conduction rod 16, a fan-shaped plate 22 fixedly mounted on the outer wall of the sliding sleeve 21, a synchronous ring 23 fixedly mounted on the outer wall of the fan-shaped plate 22, a plurality of linkage plates 24 fixedly mounted on the side wall of the synchronous ring 23, a retractable ring 25 fixedly mounted on the side walls of the plurality of linkage plates 24, a fixed ring 26 fixedly mounted on the outer wall of the conduction rod 16, and a plurality of nylon threads 27 fixedly mounted on the outer wall of the fixed ring 26 at uniform and equidistant intervals with the center of the fixed ring 26 as the axis. A control component is mounted on the bearing plate 12, and an oiling component is arranged in the conduction rod 16.

[0029] The control assembly includes an electric rod 28 fixedly mounted on the side wall of the bearing plate 12 , and a push rod 29 fixedly mounted on the telescopic end of the electric rod 28 , one end of the push rod 29 being fixedly connected to the side wall of the sector plate 22 .

[0030] Specifically, during the spinning process of the blank, friction will produce a lot of small wastes. If these wastes are not handled in time, they will cause the wastes to scratch the inner wall of the blank in the subsequent spinning process, affecting the appearance quality of the product. At the same time, the spinning wheel 17 processes the inner wall of the blank for multiple passes. Therefore, after each spinning pass of the spinning wheel 17, the staff needs to clean the waste on the inner wall, which affects the spinning efficiency.

[0031] The cleaning component is used to clean the waste on the inner wall of the blank after the spinning expansion. When the rotary wheel 17 spins and expands the inner wall of the blank, the electric rod 28 extends the push rod 29 through the telescopic end. During the extension process, the push rod 29 drives the synchronous ring 23 to move along the horizontal direction of the conductive rod 16 through the fan-shaped plate 22. During the movement of the synchronous ring 23, the linkage plate 24 drives the retractable ring 25 to move synchronously. During the movement of the retractable ring 25, the multiple nylon threads 27 are in a tightened state (refer to Figure 5 ), the tightened nylon wire 27 will not affect the normal spinning expansion of the roller 17. After the roller 17 has spun and drawn one pass, that is, the roller 17 is at the deepest part of the blank, the electric rod 28 retracts the push rod 29 and drives the retracting ring 25 to retract simultaneously. The retracting ring 25 releases the tightening of the multiple nylon wires 27, so that the nylon wires 27 rotate synchronously with the conductive rod 16 at high speed. The high-speed rotating nylon wires 27 are unfolded under the action of centrifugal force. At this time, the roller 17 is retracted, and the nylon wires 27 move back in a circle with the roller 17. In the process of moving back, the nylon wires 27 can directly expand a The waste generated by the first spinning is swept out of the inner wall of the blank (and after the nylon wire 27 rotating at a high speed on the conduction rod 16 completes the cleaning of the inner wall of the blank, the high-speed rotating nylon wire 27 can clean the waste inside the nylon wire 27 through centrifugal force, and then the nylon wire 27 can clean the waste on the inner wall without the need for additional cleaning of the nylon wire 27 and can be directly used next time), directly completing the cleaning of the blank, so that the spinning wheel 17 can directly perform the second pass without the need for additional manual cleaning, thereby effectively improving the spinning efficiency and quality.

[0032] The remaining structures are the same as those of Example 1.

[0033] Example 3, reference Figure 7-Figure 8, which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the oiling component includes a conduction groove 30 opened in the conduction rod 16, an extension tube 31 slidably installed at one end of the conduction rod 16, a nozzle 32 fixedly installed on the side wall of the extension tube 31, a cooling tube 33 fixedly installed on the outer wall of the conduction rod 16, and the cooling tube 33 is connected to the conduction groove 30, a plurality of liquid outlet holes 34 opened on the side wall of the cooling tube 33, a rotary joint 35 rotatably installed at one end of the conduction rod 16 away from the extension tube 31, an oil pump 36 fixedly installed on the side wall of the conversion box 9, and an oil outlet pipe 37 fixedly installed on the side wall of the oil pump 36, and one end of the oil outlet pipe 37 is rotatably connected to one end of the rotary joint 35.

[0034] An oil inlet pipe 40 is installed on the side wall of the conversion box 9, and an upper oil pipe is installed on the side wall of the oil pump 36, and one end of the upper oil pipe is connected to one end of the oil inlet pipe 40. A waste box 38 is installed on the bottom plate 1, and a discharge valve 39 is installed on the side wall of the waste box 38.

[0035] Specifically, the conduction groove 30 in the conduction rod 16 is used for the flow of spinning oil, and one end of the oil inlet pipe 40 is fixedly connected to an oil barrel (not shown in the figure), and the spinning oil in the oil barrel is pressed into the conduction groove 30 on the conduction rod 16 through the oil pump 36. After the spinning oil enters the conduction groove 30, the spinning oil is sprayed out through the cooling cylinder 33 and the nozzle 32 under the action of pressure. The spinning oil sprayed by the nozzle 32 acts on the area to be spun, so that when the spinning wheel 17 spins the inner wall area of ​​the blank, it is ensured that there is enough spinning oil covering the area to be spun to ensure the quality of spinning. The spinning oil sprayed by the cooling cylinder 33 is used for cooling. When the spinning of the spinning wheel 17 is completed and moves inward, the spinning oil sprayed by the cooling cylinder 33 can directly cool the area after the spinning is completed to ensure the quality of spinning. At the same time, the extension tube 31 is slidably installed on one end of the conductive rod 16, so that when the rotating wheel 17 spins the innermost inner wall of the blank, the extension tube 31 can be retracted into the conductive rod 16 without affecting the normal spinning of the rotating wheel 17.

[0036] The spinning oil and waste materials cleaned by the nylon thread 27 flow directly into the waste box 38 for collection. When the waste materials in the waste box 38 reach a predetermined value, the staff can open the discharge valve 39 to discharge the waste materials in the waste box 38 and collect them for treatment.

[0037] The remaining structure is the same as that of Example 2.

[0038] Based on Examples 1-3, the working principle of the present invention is as follows: the staff places the blank to be spun in the mold cylinder 20, and the clamping plate 19 clamps the end of the blank, adjusts the rotating wheel 17 to the specified area through the servo motor 11, and turns on the drive motor, oil pump 36 and control components.

[0039] In the initial state, the telescopic end of the electric rod 28 is in an extended state, the retracting ring 25 tightens the multiple nylon threads 27, the driving motor drives the rotating wheel 17 to rotate at a high speed, and the control component controls the horizontal movement of the rotating wheel 17. The rotating wheel 17 performs spinning and expanding treatment on the inner wall of the blank from the outside to the inside. Because the nozzle 32 is in front of the rotating wheel 17, the nozzle 32 rotates with the conductive rod 16 and sprays the spinning oil on the front area to be spun. After the spraying, the rotating wheel 17 performs spinning and expanding treatment on the inner wall. After the spinning is completed, the rotating wheel 17 continues to move toward the inner wall of the blank. At this time, the spinning oil sprayed by the cooling cylinder 33 cools the area after the spinning.

[0040] After the roller 17 completes one pass of spinning on the inner wall of the blank, the roller 17 is located at the innermost part of the inner wall of the blank. At this time, the telescopic end is retracted by the electric rod 28, and then the retracting ring 25 is driven to be retracted through the fan-shaped plate 22 and the synchronous ring 23. The retracting ring 25 cancels the tightening of the nylon thread 27. At this time, the nylon thread 27 rotates and unfolds at high speed with the conductive rod 16, so that the nylon thread 27 completely covers the inner wall of the blank. At this time, the roller 17 moves outward to drive the nylon thread 27 to move synchronously. The moving nylon thread 27 sweeps out the waste generated by one pass of spinning, completing the cleaning of the inner wall of the blank. After the roller 17 is fully extended, the telescopic end of the electric rod 28 is controlled to extend again, so that the nylon thread 27 is retracted, and the position of the roller 17 is controlled to perform a second pass of spinning on the inner wall of the blank, and the above operation is repeated until the spinning and expansion are completed.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
