Description

Technical Field

[0001] This utility model relates to the field of power fittings processing technology, and in particular to a power fittings stamping device. Background Technology

[0002] Traditional power fittings are metal accessories that connect and combine various devices in a power system to transmit mechanical loads, electrical loads, etc., and require stamping equipment in the production and processing process.

[0003] For example, in a power fitting stamping device with announcement number CN212664670U, the power fitting is clamped by two sliding plates sliding relative to each other, and then the pressure plate is raised by a cylinder to clamp the power fitting vertically. However, because the existing technology does not have a lower support mold between the two sliding plates, the stamping structure tends to apply force to the area near the stamping point, causing deformation of the overall structure of the power fitting and affecting the stamping quality. In addition, although the existing technology can perform stamping operations on multiple power fittings at once, after one power fitting is stamped, it is still necessary to wait for the other structural parts to be stamped. Only after all power fittings have been stamped can they be removed from between the sliding plates. There is still room for improvement in terms of improving work efficiency. Therefore, there is an urgent need for a power fitting stamping device to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-4 This utility model provides a stamping device for power fittings, comprising:

[0031] Machine base 1, with a support frame 2 fixedly connected to its top surface;

[0032] Support plate 3 is movably connected to support frame 2, and upper mold 6 is fixedly connected to the bottom surface of support plate 3;

[0033] A pair of pressure rods 15 are symmetrically distributed along the center of the upper mold 6, and the pressure rods 15 are elastically slidably connected to the support plate 3;

[0034] Turntable 5 is mounted on the top surface of machine base 1. Several lower molds 7 are fixedly connected to the top surface of turntable 5 at equal intervals around its circumference. A driving component is provided on machine base 1. The driving end of the driving component is connected to turntable 5 so that the several lower molds 7 are matched with the upper molds 6 in the vertical direction one after another.

[0035] A pair of clamping plates 8 are symmetrically distributed along the center of the lower mold 7. A control component is provided on the machine base 1. The control end of the control component is connected to the pair of clamping plates 8 so that the pair of clamping plates 8 can move closer to or further away from each other.

[0036] In this technical solution, the power fittings to be stamped are placed in the lower mold 7, and the turntable 5 drives several lower molds 7 to rotate, so that the lower molds 7 are matched one by one with the upper mold 6. After the upper mold 6 and the lower mold 7 are aligned, the lower mold 7 is moved by the support plate 3 to perform the stamping operation. During the process, the pressure rod 15 is elastically slidably connected to the support plate 3 to fix the power fittings in the vertical direction. Compared with the prior art, the stamping quality of the power fittings to be stamped is improved by the cooperation of the upper mold 6 and the lower mold 7, combined with a pair of clamping plates 8 to hold and fix the power fittings. Moreover, after one stamping is completed, the lower mold 7 is replaced by rotating the turntable 5, and the stamped power fittings are transported out of the stamping area of ​​the upper mold 6, which facilitates timely removal of finished products and improves work efficiency.

[0037] Specifically, the upper mold 6 and the lower mold 7 preferably adopt, but are not limited to, the common power clamp mold structure.

[0038] Furthermore, the projection of the upper mold 6 along the vertical direction coincides with the top surface of the lower mold 7 located directly below.

[0039] By ensuring the overlap of the dimensions of the upper mold 6 and the lower mold 7, the fitting and matching degree is guaranteed when the support plate 3 moves down to drive the upper mold 6 to stamp, thereby improving the stamping quality.

[0040] Furthermore, the support frame 2 is an L-shaped plate structure, and the short side of the support frame 2 is set above one side of the turntable 5 in a horizontal direction. A hydraulic cylinder 9 is fixedly connected to the bottom surface of the short side of the support frame 2, and the piston end of the hydraulic cylinder 9 extends vertically downward and is fixedly connected to the support plate 3.

[0041] The hydraulic cylinder 9 drives the support plate 3 to move downward, and the support plate 3 drives the upper mold 6 to descend, so that it fits with the lower mold 7 to realize the stamping operation.

[0042] Furthermore, the driving component includes a stepper motor 10, which is fixedly connected to the top surface of the machine base 1, and the output shaft of the stepper motor 10 is fixedly connected to the bottom axis of the turntable 5.

[0043] The rotation angle of the turntable 5 is effectively controlled by the stepper motor 10. The specific angle value of a single rotation of the turntable 5 is known by combining the number of lower molds 7, thereby realizing the accurate vertical correspondence between several lower molds 7 and the upper mold 6.

[0044] Furthermore, it also includes:

[0045] The base plate 11 is fixed to the top surface of the machine base 1. The base plate 11 is located directly below the support plate 3. The top surface of the base plate 11 is fixed with a slide rail 12. The bottom surface of the turntable 5 is provided with a slide groove. The slide rail 12 slides in contact with the slide groove, and the slide rail 12 slides in contact with the inner wall of the top of the slide groove.

[0046] The slide rail 12 is slidably connected to the turntable 5, and the base plate 11 and the slide rail 12 cooperate to support the turntable 5. When the upper mold 6 presses, the pressure is applied to the turntable 5, the base plate 11 and the slide rail 12 can keep the turntable 5 stable, prevent all the force from being applied to the output shaft of the stepper motor 10, and improve the service life of the overall structure.

[0047] Furthermore, the control components include a bidirectional lead screw 13, a groove is provided on the top surface of the turntable 5 below the lower mold 7, the bidirectional lead screw 13 is rotated in the groove, a pair of clamping plates 8 are symmetrically slidably connected to both ends of the groove along the center of the bidirectional lead screw 13, and the clamping plates 8 are threaded on the bidirectional lead screw 13, and the output shaft of the drive motor 14 is coaxially fixed to one end of the bidirectional lead screw 13, the drive motor 14 is fixed in the turntable 5.

[0048] The drive motor 14 drives a pair of clamping plates 8 to move in opposite directions to clamp and fix the power fittings placed on the lower mold 7, and can correct their position. The pair of clamping plates 8 are symmetrical about the center of the bidirectional lead screw 13, and the center of the lower mold 7 is aligned with the bidirectional lead screw 13 in the vertical direction, so that the center of the power fittings can correspond to the center of the lower mold 7, ensuring the stamping effect.

[0049] Furthermore, the pressure rod 15 passes through the support plate 3 in a vertical direction, and a baffle 16 is fixedly connected to the top of the pressure rod 15. The two ends of the spring 17 are respectively fixed between the baffle 16 and the top surface of the support plate 3, and the spring 17 is wound around the pressure rod 15.

[0050] The pressure rod 15 is slidably connected to the support plate 3 and the baffle 16 limits the pressure rod 15 to the support plate 3. The spring 17 provides elastic support force, so that the pressure rod 15 has an elastic tendency to move vertically downward, which stabilizes the power fittings during stamping.

[0051] Furthermore, a pressure plate 18 is fixedly connected to the bottom end of the pressure rod 15, and a groove is opened on the bottom surface of the support plate 3, with the pressure plate 18 corresponding to and matching the groove.

[0052] The pressure plate 18 has a groove. As the pressure plate 18 contacts the power fitting, it is pressed and fixed. At the same time, the upper mold 6 continues to move downward. After the pressure plate 18 extends into the groove, the bottom surface of the upper mold 6 is in complete contact with the power fitting. Meanwhile, the lower mold 7 provides support from the opposite direction, thus realizing the stamping of the power fitting.

[0053] The working principle of the electric fitting stamping device of this utility model:

[0054] The stepper motor 10 rotates the turntable 5, aligning the lower die 7 vertically with the upper die 6. The hydraulic cylinder 9 drives the support plate 3 to move downwards to stamp the power fittings. During this process, the bidirectional lead screw 13 drives a pair of clamping plates 8 to move towards each other to clamp and fix the power fittings. The lower die 7 can limit the position of the clamping plates 8, ensuring that the distance between the pair of clamping plates 8 is not less than the length of the lower die 7. This allows the upper die 6 and the lower die 7 to effectively perform the stamping operation. The pressure rod 15 stabilizes the power fittings vertically. As the upper die 6 moves downwards, the pressure rod 15 rises, causing the pressure plate 18 to extend into the groove, ensuring the fit between the upper die 6 and the surface of the power fittings, thereby improving the stamping quality and efficiency.
