Description

Technical Field

[0001] The utility model relates to the technical field of wheel rim blanking molds, in particular to a wheel rim blanking mold. Background Art

[0002] Steel wheels are welded together by welding the spokes and rims into a whole. In the wheel manufacturing process, the two key processes of fine expansion and shaping of the rim and synthetic press-fitting of the spokes and rim need to be completed by molds. Currently, the rims are manually loaded and unloaded from the mold on the equipment table. The upper and lower molds press the rims so that the two ends of the rims are in the shape of trumpets that expand outward. After the rims are pressed by the molds, the molds deform the two ends of the rims. Sometimes the rims get stuck on the lower mold, and the staff need to knock the molds or other laborious methods to demold them, which leads to reduced blanking efficiency and reduced productivity. Therefore, a rim blanking mold is proposed, which can quickly and easily demold the rims to improve their blanking efficiency and thus improve the production efficiency of the rims.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] In order to facilitate and quickly demould the rim to improve its blanking efficiency and enhance the production efficiency of the rim, as an embodiment of the present invention, Figures 1-4 As shown, a rim blanking die according to the present invention comprises a lower workbench 1 and a clamp 11. An electric cylinder 4 is fixedly installed inside the lower workbench 1. The output end of the electric cylinder 4 is fixedly connected to the bottom end of the piston push rod 3. The top end of the piston push rod 3 is fixedly connected to the bottom center of the push plate 5. The top end of the push plate 5 is provided with a push rod 7. There are multiple push rods 7. A cavity 2 is provided inside the lower workbench 1. The cavity 2 is used for the movement of the push plate 5.

[0027] Arc-shaped clamps 10 are provided at both ends of the clamp 11 away from the handle, and rubber layers 14 are provided on the inner sides of the two arc-shaped clamps 10 .

[0028] During use, if the rim 12 is stuck in the lower mold 6, the electric cylinder 4 can be started by an external power supply, and the electric cylinder 4 drives the piston push rod 3 to push upward. The piston push rod 3 will push the push rod 7 out of the lower workbench 1, pushing the rim 12 upward, so that the rim 12 is separated from the lower mold 6. Then the staff only needs to hold the handle of the clamp 11 and put the arc-shaped clamps 10 at both ends of the clamp 11 on the outside of the rim 12. By controlling the clamp 11, the two arc-shaped clamps 10 clamp the rim 12 and make the rubber layer 14 contact with the outside of the rim 12 to increase the friction between the arc-shaped clamp 10 and the rim 12, making it convenient to carry and move the rim 12.

[0029] It should be noted that the working principle of the clamp 11 is similar to that of scissors. By holding the handle of the clamp 11, the clamp 11 can be manipulated to move the arc-shaped clamps 10 closer to or farther away from each other. In this way, when loading or unloading the rim 12, the clamp 11 can be used to assist in loading and unloading.

[0030] For example, Figure 1-4 As shown, the present invention also includes that a through hole 13 is provided at the top of the lower workbench 1 , and the through holes 13 are provided in multiple locations, and the multiple through holes 13 are used for the ejector rod 7 to pass through.

[0031] During use, the through hole 13 is provided to allow the ejector rod 7 to be ejected from the through hole 13 .

[0032] For example, Figure 1-4 As shown, the present invention also includes that a lower mold 6 is fixedly provided on the top of the lower workbench 1 .

[0033] When in use, the rim 12 can be placed on the top of the lower mold 6 and then pressed in conjunction with the upper mold 8 .

[0034] For example, Figure 1-4 As shown, the present invention further comprises an upper workbench 9 movably provided just above the lower workbench 1 , and an upper mold 8 is fixedly provided at the bottom end of the upper workbench 9 . The upper mold 8 is located just above the lower mold 6 .

[0035] When in use, the upper workbench 9 descends to cause the upper mold 8 and the lower mold 6 to press the rim 12 so that both ends of the rim 12 are in a trumpet shape that expands outward.

[0036] It should be noted that the lifting and lowering of the upper workbench 9 is achieved through other mechanical mechanisms, which are not drawn or marked in the figures.

[0037] For example, Figure 1-4 As shown, the present invention further includes that a rim 12 is placed at the top of the lower mold 6 of the lower workbench 1 , and the bottom end of the rim 12 is located above the through hole 13 .

[0038] When in use, the bottom end of the rim 12 is located above the through hole 13 , allowing the push rod 7 to push the rim 12 upward.

[0039] When the utility model is in use, the rim 12 is first placed on the top of the lower mold 6, and the upper mold 8 and the lower mold 6 are pressed against the rim 12 by the lowering of the upper workbench 9, so that the two ends of the rim 12 are in the shape of a trumpet that expands outwards. When the rim 12 needs to be unmolded, the upper workbench 9 is first raised by one end to separate the upper mold 8 from the rim 12. At this time, if the rim 12 is stuck in the lower mold 6, the electric cylinder 4 can be started by an external power supply, and the electric cylinder 4 drives the piston push rod 3 to push upward, and the piston push rod 3 pushes upward to drive The push plate 5 is pushed vertically upward in the cavity 2, so that multiple push rods 7 can be pushed out from the perforation 13, pushing the rim 12 upward, and allowing the rim 12 to separate from the lower mold 6. Then the staff only needs to hold the handle of the clamp 11 and put the arc-shaped clamps 10 at both ends of the clamp 11 on the outside of the rim 12. By controlling the clamp 11, the two arc-shaped clamps 10 clamp the rim 12 and make the rubber layer 14 contact the outside of the rim 12 to increase the friction between the arc-shaped clamp 10 and the rim 12, making it easier to carry and move the rim 12.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
