Problems solved by technology

[0005] Aiming at the problem that the bending accuracy of the above-mentioned existing devices is not easy to control for small deformations, and because the pins to be bent are equivalent to cantilever beams when they are stressed, it is easy to cause the failure of the connection between the pins and the base of the network transformer during the bending process. The invention provides a pin bending equipment

Embodiment 1

[0022] Such as Figure 1 to Figure 3 As shown, a pin bending equipment includes a frame 8, a vertical pressing bar 1 arranged on the frame 8, a deformed pressing block 7 fixed on the lower end of the pressing bar 1, and a The material table 4, the pressure rod 1 can move along its axial direction, the material table 4 is also provided with a groove width adjustment part 5, and a facing deformation briquetting block is formed between the groove width adjustment part 5 and the material table 4 7 and a bending groove 2 with adjustable width; the deformed pressing block 7 is also provided with an accommodating hole 9 .

[0023] In this embodiment, the deformed briquetting block 7 is set to have an L-shaped cross-section, any side of the deformed briquetting block 7 is located in the vertical direction, and the accommodating hole 9 is located on the side where the deformed briquetting block 7 is located in the vertical direction. During the bending process, under the compressive s...

Embodiment 2

[0025] 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.

[0026] In order to facilitate the working efficiency of the present invention, to facilitate the switching of working states and to simplify the structure of the driving part of the pressing rod, the driving part of the pressing rod is an air cylinder 6 .

Embodiment 3

[0028] The present embodiment is further limited on the basis of embodiment 1, as Figure 1 to Figure 3 As shown, in order to make the pin and the material table 4 only produce the active force positioned at the axial direction of the pressure rod 1, which is beneficial to the working quality of the present invention, the upper surface of the material table 4 is stepped, and the material table 4 is also An accommodating slot 3 for placing the base and cover of the network transformer is provided.

[0029] In order to simplify the structure of the groove width adjustment part 5, the groove width adjustment part 5 includes a screw rod 52 threadedly connected with the material table 4 and a supporting table 51 with a clearance fit with the screw rod 52, and the position of the supporting table 51 is fixed on the axis of the screw rod 52 . In the above structure, the purpose of changing the width of the bending groove 2 is achieved by rotating the screw 52 to brake the movement o...

Abstract

The invention discloses pin bending equipment. The pin bending equipment comprises a frame, a pressing rod arranged on the frame and vertically arranged, a deformation pressing piece fixed to the lower end of the pressing rod and a material table positioned below the deformation pressing piece, wherein the pressing rod can move along the axial direction of the pressing rod; the material table is provided with a groove width adjusting part; a bending groove which rightly faces the deformation pressing piece and is adjustable in width is formed between the groove width adjusting part and the material table; the deformation pressing piece is provided with an accommodating hole. The pin bending equipment is simple in structure, is favorable for protecting connection of a pin with a network transformer pin, and provides convenience for accurately controlling the deformation of the pin.

Description

technical field [0001] The invention relates to the field of equipment used in the manufacture of network transformers, in particular to a pin bending equipment. 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 the width between two rows of pins. [0004] In the prior art, there is a device for ben...
