In one embodiment of the present invention, referring to fig. 1 to 5, the upper die hard stripping terminal riveting device includes a lower die holder 100, an upper die holder 200, a slider 300, a riveting upper die 400, a stripper plate 500, a stripper 600 and a limiting member 700. The back surface of the upper die holder 200 extends with a supporting portion 201 fixedly connected with the lower die holder 100. The sliding block 300 is slidably connected to the front side of the upper die holder 200, and a connection part for connecting a power member of the terminal machine is provided on the sliding block 300, and the sliding block 300 can be pushed to slide up and down by the power member of the terminal machine. The rivet upper die 400 is disposed at the front side of the slider 300, and the bottom end of the rivet upper die 400 protrudes from the bottom end of the slider 300. The limiting piece 700 is arranged on the front side of the upper die holder 200, an extrusion surface 701 and a clearance step surface 702 are arranged at the lower end of one side, close to the sliding block 300, of the limiting piece 700, the clearance step surface 702 is far away from the sliding block 300, and the extrusion surface is close to or gradually close to the sliding block 300. The pushing plate 500 is slidably disposed at one side of the lower end of the rivet upper die 400. The pushing block 600 is obliquely and slidably connected with the sliding track of the sliding block 300 or the riveting upper die 400, and the bottom end of the pushing block 600 is used for pushing the pushing plate 500. The sliding block 300 moves upwards, and the upper end of the pushing block 600 gradually contacts with the pressing surface 701 from the clearance step surface 702, so that the pushing block 600 pushes the pushing plate 500 downwards. In the terminal crimping device of the present embodiment, when the terminal is crimped on the cable, the terminal and the cable are placed at the bottom end of the crimping upper die 400, and the slider 300 and the crimping upper die 400 are pushed to descend by the power unit of the terminal machine, so that the crimping upper die 400 and the lower die 800 rivet the terminal and the cable together. When the slider 300 and the riveting die 400 slide downwards, the push block 600 moves downwards along with the slider, so that the upper end of the push block 600 is located at one side of the clearance step surface 702, and therefore, the push block 600 cannot apply pressure to the push plate 500, when the riveting die 400 and the lower die rivet a terminal, the push plate 500 can move upwards freely to yield when receiving the interference force of the lower die 800 or the terminal, and the interference of the terminal and the riveting of a cable is avoided. When the slider 300 and the riveting die 400 move upward to return materials, the push block 600 also moves upward along with the slider 300 and the riveting die 400, and the upper end of the push block 600 contacts with the pressing surface 701 while moving upward, the push block 600 is pushed to slide obliquely downward by the pressing surface 701, and the lower end of the push block 600 contacts with the push plate 500 while sliding downward, so that the push plate 500 is pushed to return materials downward. And the ejector pad 600 is adopted to carry out material returning in a hard extrusion mode, so that the material returning effect can be completely realized, and the problem that the terminal is blocked on the riveting upper die is avoided.
Further, referring to fig. 1 to 4, the upper end of the pushing block 600 is an arc surface. In this embodiment, the upper end of the push block 600 is configured as an arc surface, so that the upper end of the push block 600 is in line contact with the pressed surface 701, thereby reducing the contact area and friction.
Further, referring to fig. 1 to 4, a sliding groove 301 inclined to the sliding track of the sliding block 300 is provided at the front side of the sliding block 300, and the pushing block 600 is disposed in the sliding groove 301. The stripper plate 500 is disposed between the slider 300 and the riveting die 400. In the present embodiment, the push block 600 is disposed in the sliding groove 301 of the slider 300, which increases the sliding stability of the push block 600 and makes the connection between the riveting die 400 and the slider 300 tighter. And when the riveting upper die 400 is replaced, the push block 600 does not need to be removed, and the replacement is convenient.
Further, referring to fig. 1 to 4, a vertical guide groove 401 is provided at the lower end of the riveting upper die 400, a guide block 501 is provided at the upper end of the pushing plate 500, and the guide block 501 freely slides into the guide groove 401. Thus enabling the stripper plate 500 to be captured between the slider 300 and the rivet upper die 400.
Further, a space-avoiding installation position is further provided at the lower end of the front side of the slider 300, and the pushing plate 600 is disposed in the space-avoiding installation position. Therefore, when the riveting die 400 is connected with the slider 300, the riveting die 400 can be tightly attached to the slider 300, so that the structure is more compact and simpler.
Further, referring to fig. 4, the included angle between the pushing block 600 and the sliding track of the sliding block 300 is 15 ° to 45 °. In this angular range, the pusher plate 500 can be pushed to completely push off the riveted terminal in the stroke in which the slider 300 slides. And when the push block 600 contacts the pressing surface 701, the force arm formed by the downward force applied to the push block is short, so that the push block 600 is not deformed by the excessive impact force. More preferably, the angle between the sliding track of the pushing block 600 and the sliding track of the sliding block 300 is preferably 25 °.
Further, referring to fig. 4, the step surface 702 is a vertical surface, and the pressing surface 702 is an inclined surface or an arc surface; the upper end of the pressing surface 701 is a vertical surface. In this embodiment, when the upper end of the pushing block 600 contacts the vertical surface through the pressing surface 701, the pushing block 600 will not receive the pressing force, that is, the pushing block will not continue to push the pushing plate 500, so as to protect the pushing plate 500.
Further, referring to fig. 2, two riveting positions are further provided at the lower end of the riveting upper die 400, and two independent lower dies 800 are further provided on the lower die holder 100 in parallel; two lower dies 800 are respectively arranged on two independent pressure sensors. In this embodiment, both terminals may be riveted at the same time. Therefore, the pushing block 600 is adopted to push the pushing plate 500, so that the whole structure is simple, and a structure which is in conflict with the pushing plate 500 is arranged on the lower die 800, or only a part of stress points are needed to be arranged, so that the structure of pushing the pushing plate by a traditional spring is replaced, the traditional lower die is required to be provided with an extrusion position of the pushing plate, the pushing plate can overcome the elasticity of the spring, and the upper die can complete terminal riveting, so that a larger contact position is required to be arranged on the lower die. The lower mold 800 of the present embodiment does not need to set a larger contact position, and the implementation structure is more compact, so that two lower molds 800 can be independently set. The pressure sensor is arranged to detect the stress during riveting, so that the riveting pressure can be well controlled, and the stress of the two lower dies 800 can be regulated to be uniform and stable.
Further, referring to fig. 1, the lower die holder 100 is further provided with a protection plate 810 positioned at the front end of the lower die. The front end of the riveting upper die 400 is also provided with a protection plate 410, and two clearance holes 411 are arranged on the protection plate 410. The two protection plates can protect the operator well, and the two clearance holes 411 are used for guiding two cables between the riveting upper die 400 and the lower die 800.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
