Embodiment 1

[0027] Such as Figure 1 to Figure 3 As shown, the network transformer pin bending mechanism that is convenient for controlling the amount of deformation includes a frame 8, a pressing bar 1 arranged on the rack 8, a deformed pressing block 7 fixed at the lower end of the pressing bar 1, and a deformation pressing block 7 located below The material platform 6, the pressure rod 1 can move along its axial direction, and also includes a deformation control mechanism, and a pin tightening device is also fixed on the pressure rod 1;

[0028] The pin tightening device comprises a spring seat 3, a spring 4 and a positioning pressing block 5, the spring seat 3 is fixed on the pressing bar 1, and the two ends of the spring 4 are fixedly connected with the spring seat 3 and the positioning pressing block 5 respectively, and the spring The axis of 4 is parallel to the axis of pressure rod 1, and the lower end position of positioning briquetting block 5 is lower than the lower end positio...

Embodiment 2

[0035] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As shown, in order to drive the pressing rod 1 conveniently, the upper end of the pressing rod 1 is also fixedly connected with a pressing rod driving part. According to the size of the workload, the set pressure rod driving part can be set in the structural form of artificial compressive stress drive or hydraulic pressure or air pressure drive.

[0036] In order to facilitate the working efficiency of the present invention, facilitate switching of working states and simplify the structure of the pressing rod driving part, the pressing rod driving part is an air cylinder 9 .

Embodiment 3

[0038] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As shown, in order to prevent the positioning pressing block 5 from being skewed relative to the deformed pressing block 7 after the interaction force is generated with the pins, it also includes a guide rod 2, the axis of the guide rod 2 is in line with the The axes of the spring 4 are parallel, the lower end of the guide rod 2 is fixedly connected with the positioning pressure block 5 , and the spring seat 3 is also provided with a hole which is loosely matched with the guide rod 2 .

[0039] In order to enhance the ability to limit the movement direction of the positioning pressure block 5 and prevent the uneven deformation of the spring 4, there are more than one guide rod 2, and one of the guide rods 2 is located in the inner ring of the spring 4.

Abstract

The invention discloses a network transformer pin bending mechanism facilitating control of deformation. The pin bending mechanism comprises a machine frame, a pressure rod arranged on the machine frame, a deformation pressing block fixed to the lower end of the pressure rod, and a material table located on the lower side of the deformation pressing block, the pressure rod can axially move. The pin bending mechanism further comprises a deformation control mechanism and is further fixedly provided with a pin fastening device, the pin fastening device comprises a spring base, a spring and a positioning pressing block, the spring base is fixed to the pressure rod, the two ends of the spring are fixedly connected with the spring base and the positioning pressing block respectively, the axis of the spring is parallel with that of the pressure rod, the lower end of the positioning pressing block is lower than the lower end of the deformation pressing block, the positioning pressing block and the deformation pressing block are respectively provided with a containing hole, and the deformation control mechanism comprises a push rod bolt and a spacing screw cap. The pin bending mechanism is simple in structure, the situation that matching precision of pins and pin holes is not high due to the fact that the distance between the pins is changed after bending machining can be avoided and the bending degree of the pins can be conveniently controlled.

Description

technical field [0001] The invention relates to the field of equipment used in the manufacture of network transformers, in particular to a bending mechanism for network transformer pins which is convenient for controlling the amount of deformation. Background technique [0002] Network transformers are widely used in high-performance digital switches; SDH / ATM transmission equipment; ISDN, ADSL, VDSL, POE power receiving equipment integrated business digital equipment; FILT optical fiber loop equipment; Ethernet switches and other equipment. [0003] The network transformer mainly includes a base, a cover, pins, and coils arranged between the pins. At the same time, the pins on the network transformer are generally arranged in two rows. In the prior art, the pins on the packaged network transformer are mostly needle-shaped. However, in practical applications, since the pin holes configured for the pins have different widths, it is often necessary to bend the pins to change th...
