Description

Technical Field

[0001] The utility model relates to the technical field of optical communication device processing, in particular to a pin forming device. Background Art

[0002] like Figure 5 The optical module in the optical communication device has insufficient opening of its pins after processing, which will affect the welding operation of the pins and the circuit board. Therefore, when processing the optical module, it is necessary to first open the pins with a correction jig. However, the correction jig currently used lacks the necessary limit for the pins during correction, so the root of the pins is prone to deformation, and this deformation will affect the connection between the pins and the inside of the optical module. In addition, during the correction process, the problem of slight opening is prone to occur, which affects the welding operation. Utility Model Content

[0003] The utility model provides a pin forming device to solve the above-mentioned deficiencies of the prior art, solve the influence of deformation etc. on the pins during deformation, and solve the problem of uncontrollable deformation.

The first inclined surface and the inclined surface are provided to ensure the opening effect. At the same time, when the pin is bent, the opening block first moves inward and then moves outward. This operation method is convenient for inserting the pin into the through hole and making the pin part located at the inner block. Secondly, when opening and bending, the opening block is prevented from moving directly inward to cause the pin to bend.

[0006] Furthermore, a plurality of limiting grooves are formed on the upper and lower walls of the groove, the limiting grooves are connected with the through holes, and the limiting grooves play a role of limiting the pins.

[0007] Furthermore, the limiting groove is in a semicircular structure to improve the fit during limiting.

[0008] Furthermore, a plurality of restraining grooves are formed on the outer wall of the expansion block, and the restraining grooves are connected with the through holes to avoid flattening the pins during bending, thereby achieving the desired deformation purpose.

[0009] Furthermore, the restraining groove is in a semicircular structure to improve the fit.

[0010] Furthermore, a guide hole is provided on the bottom plate, a limit lower rod is movably provided in the guide hole, and a push plate is provided at the upper end of the limit lower rod;

[0011] A mounting end plate is installed on the bottom plate, and a hydraulic cylinder is installed on the upper end of the mounting end plate.

A pair of inner pressure plates are provided on the inner wall of the push plate. An inclined pressure surface is formed on the inner end of the inner pressure plate. When the inner pressure plate moves, it can act on the inner block, thereby making the inner block close to facilitate the bending of the pins. At the same time, the tension spring is also stretched. When the inner pressure plate is cancelled, the inner block will move outward under the action of the tension spring, thereby facilitating the removal of the optical module after the pins are bent. The push plate is provided with two pairs of vertical guide holes, and the opening block is provided with a pair of movable penetration rods, which are passed through the vertical guide holes. The movable penetration rods at the same height are provided with a movable horizontal plate, and spring pins are provided at both ends of the movable horizontal plate. The outer ends of the spring pins are sleeved with sleeves, and the sleeves are installed on the push plate.

The moving rods are provided with a push-pull plate, and the push-pull plate is arranged on the inner side of the push horizontal plate. The hydraulic cylinder provided above can first drive the push plate and the opening block to move inward. When the opening block is inserted into the groove, due to the obstruction of the bottom of the groove, the pushing horizontal plate and the moving rod thereon will act on the oblique hole, thereby causing the opening block to move outward, and the pins are opened and bent by the opening block.
