Detailed Description
The utility model mainly aims at forming in the third order, and the die structure for automatically forming the C4 elastic strip is shown in fig. 4 and 5, and comprises: toe end upper mould 1, well limb upper mould 2, go up die carrier 3, dog 4, reset spring 5, root end upper die base 6, root end gyro wheel 7, root end upper mould 8, root end sloping block 9, masterform 10, toe end lower mould 11, big arch height sloping block 12, equipment slider 13, equipment workstation 14 etc. wherein:
The root upper die seat 6 is provided with a root upper die 8 and a root roller 7, the root upper die seat 6 is connected with the upper die frame 3 through a pin, and the root roller 7 is connected with the root upper die seat 6 through a pin. The root upper die 8 is connected with the root upper die holder 6 through threads. The structure of the upper root die holder 6 is shown in fig. 6 and 7, and a slotted hole is formed on the upper root die holder 6 and can be used for adjusting the upper and lower positions of the upper root die 8. The main functions are as follows: the root end upper die holder 6 swings left and right to extrude the elastic strip with the root end upper die 8 through the impact of the root end roller 7 and the root end inclined block 9, so that the root end external skimming size of the elastic strip is formed.
As shown in fig. 8 and 9, a threaded hole is formed in the root end upper die 8, so that the root end upper die 8 and the root end upper die holder 6 are in threaded connection through bolts, and the elastic strip is pressed downwards while being extruded leftwards and rightwards under the driving of the root end upper die holder 6, so that two sizes of the elastic strip outer skimming and the small arch height are formed.
The structure of the large arch height inclined block 12 is as shown in fig. 10 to 12, and the large arch height inclined block 12 is connected with the large arch height base through threads, so that the main functions are as follows: in the initial state, the large arch height of the spring strip is placed on the large arch height inclined block 12, the large arch height inclined block is not moved, the large arch height dimension is formed in the process of pressing the spring strip down by the upper die, and the large arch height dimension of the spring strip can be adjusted by adding gaskets to change the height of the large arch height inclined block or moving the left and right positions of the large arch height inclined block, so that the spring strip is in a qualified range.
The structure of the root inclined block 9 is as shown in fig. 13 and 14, the root inclined block 9 is connected with the root inclined block base through threads, and the main functions are as follows: the root end roller 7 is used for bearing the impact of the root end roller in the pressing process, so that the reaction force is given to the root end roller, the vertical force part of the root end roller is converted into the horizontal direction, and the elastic strip is extruded left and right to form the root end external skimming size.
During the equipment, toe end upper die 1, well limb upper die 2 passes through the bolt with last die carrier 3 and links to each other, root end upper die base 6 passes through pin interconnect with last die carrier 3, can rotate, root end upper die 8 passes through the bolt with root end upper die base 6 and is connected with the slotted hole, root end gyro wheel 7 passes through pin interconnect with root end upper die base 6, root end upper die base 6 passes through reset spring 5 with dog 4 and is connected realization reset action, root end sloping block 9 passes through bolted connection with the lower bolster, can control sliding adjustment, masterform 10 passes through the bolt fastening on the lower bolster, toe end lower die 11 passes through the bolt and is connected on the lower bolster through the slotted hole, can adjust.
