Embodiment Construction
[0015] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.
[0016] Please refer to Figure 1-4 According to the present invention, the angle punching mold for drawing and pressing the front splint includes a lower mold and an upper mold that cooperate with each other. Wherein, the lower mold includes a lower template 1 , a lower backing plate 2 and a die positioning plate 3 which are sequentially arranged and fixedly connected from bottom to top. The center of the die positioning plate 3 is provided with a die 4, the center hole of the die 4 is provided with a locator 5 and a spring 6, and the spring 6 elastically abuts against the locator 5 and the lower Between the pads 2. Specifically, the center of the lower formwork 1 is provided with an installation hole 7, and a first bolt 8 is installed in the installation hole 7, and the first bolt 8 passes through the bottom backing pl...

The invention discloses a cold drawing, angle pressing and nail punching die of a front clamping plate. The cold drawing, angle pressing and nail punching die comprises a lower die and an upper die which are matched with each other; the lower die comprises a lower die plate, a lower backing plate and a cavity die positioning plate; the center of the cavity die positioning plate is provided with a cavity die; a positioning part and a spring are arranged in a center hole of the cavity die; the spring is connected between the positioning part and the lower backing plate in a abutting mode elastically; the cavity die is provided with a nail punching hole which is located in the lateral side of the center hole; the upper die comprises an upper die plate, a first fixed plate, an upper backing plate and a second fixed plate; the center of the second fixed plate is provided with an angle pressing die; an angle pressing groove with a chamfer, which is corresponding to the outer edge of a product, is formed in the bottom surface of the angle pressing die in a concave mode; the center of the angle pressing die is provided with a cold drawing head; the outer edge of the tail end of the cold drawing head is provided with a chamfer which is corresponding to an inner hole of the product; the angle pressing ide is provided with a punching nail which is located on the lateral side of the cold drawing head; the punching nail is corresponding to the nail punching hole. The cold drawing, angle pressing and nail punching die of the front clamping plate is high in production rate and free of material loss and reduces the cost.
Description
technical field [0001] The invention relates to a mold, in particular to a front splint blunting and pressing angle punching mold. Background technique [0002] At present, the precision of the center hole of the front splint is very high, and the outer round corners are required to be chamfered. Generally, the corners of the parts will have burrs after punching, and machining methods are required to chamfer and finish the outer circle, which reduces production. Efficiency, but also increases the loss of materials and increases the cost. Contents of the invention [0003] The object of the present invention is to provide a front splint blunting and pressing angle punching die, which solves the problems of reduced production efficiency, increased material loss and increased cost. [0004] In order to achieve the above object, the present invention provides a front splint blunting and pressing angle punching die, which includes a lower die and an upper die that cooperate wi...
