Description

Technical Field

[0001] The invention relates to the technical field of steel wire processing, in particular to a steel wire head pressing die. Background Art

[0002] The wire head pressing die is a special die used to connect one end of the wire into the wire sleeve to form a wire head and ensure that the wire is not easy to fall out of the wire sleeve. During the working process of the wire head pressing die, the wire is first loaded into the wire sleeve, and then the wire sleeve with the wire is placed into the groove of the lower die. Then, the pressing head of the upper die is driven by the cylinder to drop, and the wire sleeve and the wire are tightly fitted. This fitting method not only increases the friction between the wire and the wire sleeve, but also makes it difficult for the wire to fall out of the wire sleeve.

[0003] A Chinese patent publication numbered CN103357753A discloses a wire head pressing mold, in which a wire sleeve and the steel wire in the sleeve are punched out into a curved shape, and the steel wire is not easy to fall out of the wire sleeve. The protective rod is a steel wire with a circular cross-section. When the wire sleeve is punched to the bottom of the groove, the outer wall of the wire sleeve rubs against the circular outer wall of the protective rod, and the friction is small, which not only protects the groove wall, but also protects the outer wall of the wire sleeve, and is not easy to cause damage.

[0004] However, when the steel wire sleeve and the steel wire are stamped together, a certain amount of metal debris will inevitably be generated. These fine metal particles will remain at the bottom of the groove in the mold during the processing. When the next set of steel wire sleeves and steel wires to be assembled are put into the same mold again for a new round of bonding operations, the metal debris left behind may cause physical damage to the outer wall of the newly inserted steel wire sleeve. This damage not only affects the appearance quality of the product, but more importantly, it may cause the connection strength between the steel wire and the steel wire sleeve to decrease, thereby affecting the safety performance and service life of the entire component.

[0021] By setting the elastic moving block and the fixed block, the upper die can be buffered, so that the upper die will not have a strong impact force with the lower die, so that the upper die and the lower die are not easily damaged. During processing, the fixed block is squeezed by the upper die to drive the moving block to move, and the moving block drives the cylinder and the L-shaped rod to move through the cooperation of the inclined groove and the moving groove. The L-shaped rod drives the clamping plate to clamp and fix the steel wire, so that when the steel wire and the wire sleeve are combined for stamping, the steel wire is in a fixed state, and the steel wire and the wire sleeve are not easy to deviate from and separate from the lower die, thereby improving the combination accuracy and quality of the steel wire and the wire sleeve.

The inner walls of the lower ends of the two cavities 201 are respectively opened with installation grooves 213, and the inner walls of the installation grooves 213 are fixedly connected to the lower ends of the elastic members 212.

[0041] In this embodiment: the movable block 202 is limited by the provided cavity 201 so that the movable block 202 can move up and down, and the provided elastic member 212 applies elastic force to the movable block 202 so that the movable block 202 has an upward elastic force and buffers the movable block 202.

A hose 309 is fixedly installed on one end of the nozzle 310 . The cleaning mechanism 3 is used to clean the debris on the lower mold 106 .

[0052] In this embodiment, the air bag 302 inhales air from the air inlet pipe 304 and exhausts air from the exhaust pipe 307 through the provided air inlet pipe 304 .

[0053] Specifically, Figure 1-Figure 8 As shown, an air intake head 305 is fixedly installed at the other end of the two air intake pipes 304, and a one-way valve 306 is fixedly installed on the two air intake pipes 304.

[0054] In this embodiment, through the one-way valve 306 , the airbag 302 can only take in air from the air inlet pipe 304 , but cannot exhaust air from the air inlet pipe 304 .

[0055] Specifically, Figure 1-Figure 8 As shown, a one-way valve 308 is fixedly installed on each of the two exhaust pipes 307, two hoses 309 and two nozzles 310 are provided, the other ends of the two hoses 309 are fixedly connected to one end of the two exhaust pipes 307, the outer walls of the two nozzles 310 are fixedly installed with a fixing sleeve 311, the outer walls of the two fixing sleeves 311 are fixedly installed with a supporting rod 312, and the other ends of the two supporting rods 312 are fixedly connected to the sides of the two clamping plates 210.

Through the elastic member 212, the moving block 202 and the fixed block 203, the upper mold 105 can be buffered, so that the upper mold 105 will not have a strong impact force with the lower mold 106, so that the upper mold 105 and the lower mold 106 are not easily damaged.

When the upper die 105 is pressed downward to squeeze and combine the steel wire and the steel wire sleeve, the upper die 105 squeezes the fixed block 203 to drive the moving block 202 and the airbag 302 to move downward, so that the airbag 302 absorbs air from the air inlet head 305 through the air inlet pipe 304 and expands. Subsequently, after the upper die 105 and the lower die 106 are pressed and combined with the steel wire and the steel wire sleeve, the upper die 105 moves upward, the clamping plate 210 no longer clamps the steel wire, and the elastic member 212 pushes the moving block 202 The airbag 302 moves upward, and the upper end of the airbag 302 is squeezed against the inner wall of the upper end of the cavity 201. The gas inside the airbag 302 is sprayed from the nozzle 310 into the groove of the lower mold 106 through the exhaust pipe 307 and the hose 309, and the metal debris generated by the stamping is blown away to ensure that the next group of steel wire sleeves and steel wires to be assembled will not be damaged by the metal debris, thereby ensuring the connection strength between the steel wires and the steel wire sleeves and the safety performance and service life of the entire assembly.
