Description

Technical Field

[0001] The utility model belongs to the technical field of pins, and in particular relates to a split elastic pin used in a punching die. Background Art

[0002] A large number of pins are often used in the mold industry. Some of these pins facilitate alignment between the upper and lower molds during mold closing, while others facilitate positioning of the workpiece to be stamped and the mold. Some pins are fixed in position, while others have a certain degree of elasticity. The degree of elasticity can also affect the positioning effect to varying degrees, so it is best to fine-tune the elasticity of the pins according to actual conditions.

[0003] Most of the elastic pins used in existing punching dies are of one-piece type, which makes them bulky and inconvenient to store. In addition, during use, one end of the spring base of most elastic pins is prone to slipping, thus affecting normal use. For this reason, we propose a split elastic pin used in punching dies.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0019] See also Figure 1-3 The utility model provides a technical solution: a split elastic pin used in a punching mold, comprising a pin body 1, a first threaded column 2 is provided at the bottom of the pin body 1, a first sleeve shaft 3 is provided on the outer side of the first threaded column 2, a first limit block 4 is provided at one end of the first sleeve shaft 3, a spring 5 is provided on the surface of the first sleeve shaft 3, a second limit block 6 is provided at one end of the spring 5, a second sleeve shaft 7 is provided on one side of the second limit block 6, a second threaded column 11 is provided on the inner side of the second sleeve shaft 7, a connecting disk 10 is provided at the bottom end of the second threaded column 11, a connecting rod 9 is provided at the bottom end of the connecting disk 10, a base 8 is provided at the bottom end of the connecting rod 9, a rubber sleeve 12 is provided on the outer side of the base 8, a curved surface 13 is provided at the bottom of the rubber sleeve 12, a first conical rubber sleeve 14 is provided on the outer side of the rubber sleeve 12, and a second conical rubber sleeve 15 is provided on the outer side of the connecting disk 10.

[0020] Specifically, the bottom of the pin body 1 is fixedly connected to the first threaded column 2, the outer surface of the first threaded column 2 is threadedly sleeved with the first sleeve shaft 3, one end of the first sleeve shaft 3 is fixedly connected to the first limit block 4, the surface of the first sleeve shaft 3 is sleeved with a spring 5, one end of the spring 5 is fixedly connected to one side of the first limit block 4, one end of the spring 5 is fixedly connected to the second limit block 6, one side of the second limit block 6 is fixedly connected to the second sleeve shaft 7, one end of the spring 5 is sleeved on the outer surface of the second sleeve shaft 7, the inner side of the second sleeve shaft 7 is threadedly connected with the second threaded column 11, the bottom end of the second threaded column 11 is fixedly connected to the connecting disk 10, the bottom end of the connecting disk 10 is fixedly connected to the connecting rod 9, the bottom end of the connecting rod 9 is fixedly installed with a base 8, the outer side of the base 8 is fixedly sleeved with a rubber sleeve 12, the bottom of the rubber sleeve 12 is fixedly provided with an arc surface 13, the outer surface of the rubber sleeve 12 is glued with a first conical rubber sleeve 14, and the outer surface of the connecting disk 10 is glued with a second conical rubber sleeve 15.

[0021] In this embodiment, when the device is used, the top end of the spring 5 and the bottom end of the pin body 1 are connected by threading the first sleeve shaft 3 and the first threaded column 2, and the second end of the spring 5 and the base 8 are connected by threading the second sleeve shaft 7 and the second threaded column 11, so that the base 8, the spring 5 and the pin body 1 are combined into one. Then, one end of the base 8 is inserted into the connecting hole on the surface of the punching die, and the rubber sleeve 12 on the surface of the inner base 8 can be squeezed through the connecting hole on the surface of the punching die. The rubber sleeve 12 has a certain resilience, so that its outer surface is tightly fitted with the inner wall of the connecting hole, thereby increasing The stability of the base 8 inside the connecting hole is enhanced. When the base 8 drives the first conical rubber sleeve 14 and the second conical rubber sleeve 15 into the connecting hole, the outer conical leaves of the first conical rubber sleeve 14 and the second conical rubber sleeve 15 are inserted into the connecting hole. When the base 8 is toward the outer end of the connecting hole, the outer conical leaves of the first conical rubber sleeve 14 and the second conical rubber sleeve 15 will form a barb shape and be firmly stuck in the connecting hole, further increasing the stability of the base 8. After the pin body 1 is squeezed by the outside world, it will compress the spring 5 and then retract into the connecting hole. When the end of the pin body 1 loses the squeezing force, the spring 5 drives the pin body 1 into the other end hole of the punching die, thereby completing the connection.
