Description

Technical Field

[0001] The present invention particularly relates to a butterfly washer die and a stamping system. Background Art

[0002] Belleville washers, also known as spring washers, are designed to prevent loosening in bolt and screw connections. They are typically used in medium- or high-strength bolt and screw connections. Belleville washers utilize the tension generated by the springback of the washer after being subjected to force to prevent loosening and slipping. When the washer is installed and flattened, it ensures uniform stress distribution on the tightened parts. To further prevent loosening, the surface of the belleville washer is typically processed to create striations.

[0003] In the existing process of processing the surface streaks of butterfly washers, the upper and lower molds are generally closed by stamping to deform the surface of the gasket to form streaks. After the upper and lower molds are separated, the material can be manually loaded into the mold groove, which greatly affects the processing efficiency and is inconvenient to load the material when the mold is closed. In addition, if the upper mold accidentally falls, there is a risk of squeezing and damaging the operator's hands, which has low safety. Therefore, we propose a butterfly washer mold and stamping system. Summary of the Invention

[0004] The object of the present invention is to provide a butterfly washer die and a stamping system to solve the problems raised in the above background technology.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-6 The present invention provides a technical solution: a butterfly washer mold, comprising:

[0030] An upper mold 5, the lower surface of which is provided with a first molding groove 6;

[0031] The base 1 is arranged below the upper mold 5, and a groove 3 is opened in the middle of the upper surface of the base 1;

[0032] The lower mold 8 is arranged inside the groove 3. A rotation adjustment mechanism cooperating with the base 1 is provided on one side wall of the lower mold 8 to adjust the position of the lower mold 8, so that during stamping, one lower mold 8 is located inside the groove 3 to cooperate with the upper mold 5 for stamping. At the same time, the other lower mold 8 is moved out of the groove 3 to facilitate loading. The gasket to be processed is placed on the other lower mold 8. A second molding groove corresponding to the first molding groove 6 is opened on the lower mold 8, which is convenient for processing the surface of the butterfly washer 11 to form stripes, thereby improving the anti-loosening effect.

[0033] The guide assembly is provided on the base 1 to guide the upper mold 5 to move up and down.

[0034] Preferably, the guide assembly includes a guide column 2 and a guide hole 10. The guide column 2 is fixed on the base 1. The inner edge of the upper mold 5 is provided with a guide hole 10 that cooperates with the guide column 2, so as to facilitate better mold fitting between the upper mold 5 and the lower mold 8.

[0035] Preferably, the rotation adjustment assembly includes a fixed column 701, a rotating block 702, a ring block 705 and a locking assembly 703. The rotating block 702 is detachably connected to a side wall of the lower mold 8. A ring block 705 is integrally formed at one end of the rotating block 702. The fixed column 701 is fixed to the inner end of the base 1, and the fixed column 701 and the ring block 705 are rotatably matched to facilitate the rotation of the lower mold 8 to adjust its position. A locking groove 706 is provided on the outer surface of the ring block 705, and a locking assembly 703 that cooperates with the locking groove 706 is provided on the inner side of the base 1, so that the lower mold 8 can be quickly locked after it is rotated to a predetermined position.

[0036] Preferably, the locking assembly 703 includes a spring 7031 and a block 7032. The block 7032 is slidably installed on the inner side of the base 1, and one end of the block 7032 corresponds to the slot 706. The other end is provided with a spring 7031, which facilitates pushing the block 7032 into the inner side of the slot 706 to lock the position of the ring block 705.

[0037] Preferably, the locking grooves 706 are provided at least two places along the circumference of the ring block 705, so as to better adjust the position of the lower mold 8 and lock it.

[0038] Preferably, a push-pull handle 707 is fixed to one side wall of the rotating block 702 to facilitate better driving the rotating block 702 to move.

[0039] Preferably, a mounting groove is provided on the lower surface of the lower mold 8 , and bristles 704 are provided inside the mounting groove to facilitate cleaning the inside of the groove 3 when the lower mold 8 comes out from the inside of the groove 3 , thereby improving the cleaning effect of the inside of the groove 3 .

[0040] Preferably, at least two lower molds 8 are provided, and a magnet 9 that magnetically cooperates with the lower mold 8 is provided at one end of the inner side of the groove 3 to facilitate better contact between the lower mold 8 and the inner wall of the groove 3.

[0041] Preferably, the upper die 5 is provided with a connecting plate 4 that cooperates with an external punching machine.

[0042] A butterfly washer stamping system includes a stamping machine and a butterfly washer die. The butterfly washer die is detachably connected to the punching head of the stamping machine, so as to better process streaks on the surface of the butterfly washer 11 by changing the die.

[0043] The working principle and usage process of the present invention are as follows: when in use, the butterfly washer 11 is placed in the second forming groove on the lower mold 8, and then the rotating block 702 is rotated by pushing the push-pull handle 707. The rotating block 702 drives the lower mold 8 to enter the inner side of the groove 3. The magnetic force of 9 is used to ensure that the lower mold 8 is tightly attached to one end surface of the groove 3, so that the lower mold 8 moves into place. At the same time, the spring 7031 pushes the clamping block 7032 into the inner side of the clamping groove 706 to temporarily lock the rotating block 702. The punching head of the punching machine drives the connecting plate 4 and the upper mold 5 to descend for punching. At the same time, the operator can place the washer on the second forming groove on the other lower mold 8, and extrude the upper mold 5 and the lower mold 8 together to form a stripe on the surface of the butterfly washer 11, so as to improve the anti-loosening and anti-slip effect of the butterfly washer 11 during subsequent use. Then the lower mold 8 is rotated out from the inner side of the groove 3, and the other lower mold 8 is rotated to the inner side of the groove 3, so that the material can be loaded and unloaded quickly, thereby improving the processing efficiency.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
