Abstract
The utility model relates to a shield earthing clip body mold which is composed of an upper mold part and a lower mold part and is characterized in that the lower mold part comprises a female mold and a lower mold base; the female mold is arranged on the lower mold base; the feeding side of the female mold is provided with a feeding guide block; the upper surface of the female mold is provided with a round blanking hole, a waist-shaped blanking hole, a dumbbell-shaped material cutting hole and a blanking cavity on a moving path of a copper belt; the upper mold comprises an upper mold base, a base plate, a fixed plate and a stripper plate which are sequentially arranged; the fixed plate is provided with a round hole upper punch corresponding to the round blanking hole, a waist-shaped hole upper punch corresponding to the waist-shaped blanking hole and a material cutting upper punch corresponding to the dumbbell-shaped material cutting hole; a plurality of stair-shaped through holes are drilled in the fixed plate; screws are arranged in the stair-shaped through holes, and the lower ends of the screws are in threaded connection with the stripper plate; a spring pad is arranged between the fixed plate and the stripper plate. The shield earthing clip body mold has the following advantages that blanking and punching are performed on the belt once by virtue of the upper mold and the lower mold, and the shield earthing clip body mold is prevented from being stained with oil contamination, so that acid pickling is not needed to be performed, the product scrap rate is reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of mould, particularly a kind of bonding card clamp mould.
Background technology
Grounding clamp, for the feeder line of consumer or shielding line induced electricity are imported to ground networks, prevents that the induced electricity that thunderbolt produces from causing damage to equipment.The existing non-glue type grounding clamp of exempting from mainly comprises universal, spring type etc., as shown in Figure 1, universal bonding card clamp is rectangle sheet metal 20, and one end of described sheet metal 20 has two bolt connecting holes 21, and the other end has the waist-shaped hole 22 corresponding with these two bolt connecting holes.Traditional bonding card clamp is in the time making, and blanking and punching are separately carried out, and first need copper strips to be die-cut into segment copper sheet, then on copper sheet, hole.Because this process need is transported, therefore on copper sheet, be usually stained with greasy dirt, need to carry out pickling to improve surface gloss, but copper sheet thickness is in 0.3mm left and right, and in the time of pickling, easy bending causes and scraps, and product percent of pass is low, and production efficiency is low, manufacturing cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide the bonding card clamp mould that a kind of production efficiency is high, qualification rate is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bonding card clamp mould, formed by upper and lower mould part, its innovative point is: described counterdie comprises die, die shoe, die is arranged on die shoe, and the feed side of die is provided with two pairs of charging guide pads that are positioned at copper strips both sides, and die upper surface is stretched out in the upper end of charging guide pad, and each inner side correspondence to charging guide pad is provided with gathering sill, the upper surface flush of this gathering sill and die; Die upper surface is disposed with circular blanking hole, kidney-shaped blanking hole, dumbbell shaped fracture hole and blanking chamber from feed side to exit side on the mobile route of copper strips, and the rear in blanking chamber arranges striker plate; Patrix comprises upper bolster, backing plate, fixed head, stripper, and the lower end of upper bolster is provided with fixed head by backing plate; Circular hole upper punch, waist-shaped hole upper punch and the fracture upper punch corresponding with circular blanking hole, kidney-shaped blanking hole, dumbbell shaped fracture hole are installed on fixed head; Stripper is arranged on the below of fixed head, is drilled with some stepped through holes on fixed head, and the screw that lower end is threaded with stripper is installed in this stepped through hole, and spring cushion block is installed between fixed head and stripper; On stripper, be provided with and hold the through hole that circular hole upper punch, waist-shaped hole upper punch and fracture upper punch are passed through.
Preferably, four guide pillars through stripper are installed on described backing plate, on die, have the pilot hole corresponding with guide pillar.
The utility model has the advantage of: by upper and lower mould, copper strips is once realized to blanking and punching, avoid being stained with greasy dirt in transport process, therefore without carrying out pickling, reduce product rejection rate, enhance productivity.

The specific embodiment
Embodiment
Refer to Fig. 2, the utility model has disclosed a kind of bonding card clamp mould structure, formed by part of the upper die and part of the lower die,
Counterdie comprises die 1, die shoe 2, die 1 is arranged on die shoe 2, as shown in Figure 3, the feed side of die 1 is provided with two pairs of charging guide pads 3 that are positioned at copper strips both sides, die 1 upper surface is stretched out in the upper end of charging guide pad 3, and each inner side correspondence to charging guide pad 3 is provided with gathering sill, the upper surface flush of this gathering sill and die 1.
As shown in Figure 4, die 1 upper surface is disposed with circular blanking hole 4, kidney-shaped blanking hole 5, dumbbell shaped fracture hole 6 and blanking chamber 7 from feed side to exit side on the mobile route of copper strips, and the rear in blanking chamber 7 arranges striker plate 19.
Patrix comprises upper bolster 8, backing plate 9, fixed head 10, stripper 11, and the lower end of upper bolster 8 is provided with fixed head 10 by backing plate 9.
As shown in Figure 5, circular hole upper punch 14, waist-shaped hole upper punch 15 and the fracture upper punch 16 corresponding with circular blanking hole 4, kidney-shaped blanking hole 5, dumbbell shaped fracture hole 6 are installed on fixed head 10.
As shown in Figure 6, stripper 11 is arranged on the below of fixed head 10, is drilled with some stepped through holes on fixed head 10, and the screw 12 that lower end is threaded with stripper 11 is installed in this stepped through hole, between fixed head 10 and stripper 11, spring cushion block is installed.On stripper 11, be provided with and hold the through hole 111,112,113 that circular hole upper punch 14, waist-shaped hole upper punch 15 and fracture upper punch 16 are passed through, on stripper 11, be also provided with and hold the cavity 114 that charging guide pad 3 upper ends embed.
In addition, four guide pillars 17 through fixed head 10, stripper 11 are installed on backing plate 9, on die 1, have the pilot hole corresponding with guide pillar 13 18.
Operation principle:
Copper strips is placed between upper and lower mould, and the guide and limit by gathering sill is at the intermittent fixed-distance moving of upper surface of die 1; Upper bolster 8 is descending, stripper 11 first contacts copper strips and compresses, upper bolster 8 continues descending extrusion spring cushion block, make circular hole upper punch 14, waist-shaped hole upper punch 15 and fracture upper punch 16 on fixed head 10 carry out punching and cut off and make a clamp, horizontal reset on cope match-plate pattern 8 after completing the relevant position of copper strips through stripper 11; Copper strips moves forward again, makes the clamp after cutting off fall into blanking chamber 7 in the effect of striker plate, realizes the processing of clamp.
