It should be noted that, in this embodiment, a rectangular slot 50 is formed at a side of the upper end of the mounting seat 54 away from the alignment clamping assembly 6, and a movable supporting table 55 is slidably mounted in the rectangular slot 50, and in an initial state, the upper end surfaces of the mounting seat 54 and the movable supporting table 55 are located at the same horizontal plane, in practice, first, electronic components to be sheared are placed at the upper ends of two symmetrical bearing tables 5, and the electronic components to be sheared are borne by the mounting seat 54 and the movable supporting table 55.

In this embodiment, the two sides of the mounting seat 54 are respectively provided with an ejector 56 used in cooperation with the movable supporting table 55, so as to adjust the shearing position of the pins of the electronic component by utilizing the cooperation of the ejector 56 and the movable supporting table 55, so as to adapt to the shearing requirements of the pins of different electronic components.

Therefore, if a large number of pins of electronic components need to be sheared in sequence, the electronic components need to be placed at the upper ends of two symmetrical bearing tables 5 at first, and in order to ensure accuracy in shearing, uniformity of placement of a plurality of electronic components needs to be ensured after placement is completed, therefore, an alignment clamping assembly 6 is fixed at one end, close to each other, of the two bearing tables 5, and a jacking mechanism 4 matched with the two alignment clamping assemblies 6 is arranged in the middle of the equipment frame 1.

Therefore, in practice, after the electronic components to be subjected to pin cutting are placed on the two symmetrical carrying tables 5, a plurality of electronic components need to be aligned first, i.e. the electronic components are perpendicular to the carrying tables 5, and in order to facilitate the electronic components to be perpendicular to the carrying tables 5, a plurality of grooves are further formed on the carrying tables 5 and the upper end surfaces of the alignment clamping assemblies 6 in this embodiment for placing a plurality of electronic components to be subjected to pin cutting side by side.

Specifically, before placing the electronic components, the second hydraulic cylinder 42 is started, the horizontal plate 43 and the trapezoid seat 44 are lifted upwards, then inclined surfaces on two sides of the trapezoid seat 44 are utilized to respectively squeeze inclined surfaces of the two inclined pressing plates 61, the two inclined plates 61 are separated to two sides, the fact that non-pin parts of the electronic components are completely located in a space formed between the two supporting seats 62 is guaranteed, after placement is completed, the second hydraulic cylinder 42 is driven to slowly descend the horizontal plate 43 and the trapezoid seat 44, then the two supporting seats 62 are slowly closed under the action of elastic force provided by the buffer spring 66, the non-pin parts of the electronic components located between the two supporting seats 62 are clamped, and as the two supporting seats 62 are parallel to each other, the arrangement of the electronic components is guaranteed to be neat, and the accuracy of the pins of the electronic components is guaranteed to be cut subsequently.

It should be noted that, a buffer cushion with a certain thickness may be disposed at the contact position between the supporting seat 62 and the electronic component, so as to avoid the damage of the supporting seat 62 to the electronic component during clamping.

In this embodiment, the shearing assembly 3 and the movable supporting table 55 are matched to use the shearing of the pins of the electronic component, and because the position of the movable supporting table 55 is adjustable, the cutters need to be guaranteed to be always clung to the end face of the extending plate 552, which is far away from the mounting seat 54, when in shearing, therefore, as shown in fig. 8, the shearing assembly 3 in this embodiment includes two cutters 35 and a first hydraulic cylinder 31 fixedly mounted on the top of the side frame 2, one end of the two cutters 35, which is close to each other, is respectively fixed with two inner supporting rods 34 and two outer sleeves 33, the output end of the first hydraulic cylinder 31 is fixed with a top plate 32, the two outer sleeves 33 are respectively slidably mounted on the outer surfaces of the two inner supporting rods 34, the middle parts of one ends of the two cutters 35, which are close to each other, are respectively fixed with connecting rods 36, and the middle parts of the two connecting rods 36 are provided with hexagonal rotating columns 37, and concretely, the hexagonal rotating columns 37 are mounted on the lower ends of the top plate 32 through annular bearing seats, so that the hexagonal rotating columns 37 can only rotate around the axes, and the hexagonal rotating columns 37 cannot move in the horizontal direction, and the two inner rotating columns are provided with two opposite inner threads and two outer threads and two inner threads of the two inner threads 38 are respectively.

It can be seen that after the position of the movable supporting table 55 is adjusted, in order to make the cutter 35 always cling to the end surface of the extending plate 552 far away from the side of the mounting seat 54, only the hexagonal rotating column 37 is required to be rotated by a tool, and the two cutters 35 are close to the middle or separated to two sides by utilizing the matching of the two connecting rods 36 and the threaded sleeves 38 with opposite screw threads until the cutter 35 and the end surface of the extending plate 552 far away from the side of the mounting seat 54 are positioned on the same vertical surface, so that the cutting tool is suitable for actual cutting requirements of different sizes of pins of electronic components.

In addition, it should be specifically noted that, as shown in fig. 11, when the shearing is actually performed, a pressing plate b may be additionally provided on two symmetrical bearing tables 5, so as to fix a plurality of electronic components on the bearing tables 5, maintain stability during the shearing, and avoid deformation of pins of the electronic components during the shearing, where the mounting manner of the pressing plate b is a conventional design in the prior art, and will not be described herein.

As shown in fig. 9, the auxiliary lifting mechanism 7 includes a stabilizing plate 71, an L-shaped reinforcing plate 72 is fixed at the bottom of the stabilizing plate 71, the L-shaped reinforcing plate 72 and the stabilizing plate 71 are fixedly connected with the vertical plate 53, an inclined rail 73 is fixed at one end of the stabilizing plate 71 far away from the vertical plate 53, a through clamping groove 74 is formed in the middle of the inclined rail 73, an outer wrapping seat 77 is sleeved outside the inclined rail 73, the outer wrapping seat 77 can slide on the inclined rail 73, a telescopic column 75 is slidably mounted in the middle of the outer wrapping seat 77, the telescopic column 75 is slidably connected in the clamping groove 74, a fixing disc 76 is fixed at one end of the telescopic column 75 far away from the bearing table 5, a coil spring 78 is fixed between the fixing disc 76 and the outer wrapping seat 77, the coil spring 78 is sleeved on the outer surface of the telescopic column 75, two fixing strips 79 are symmetrically fixed at one outer surface of the telescopic column 75 far away from the fixing disc 76, and one end of the two fixing strips 79 close to the cutter 35 are both fixed with the straight plate 70.

It should be noted that the telescopic column 75 is of a two-stage telescopic structure, and can be freely adjusted in length and fixed by bolts.

In addition, the cutter 35 is provided with a clamping groove 701 matched with the straight plate 70, the straight plate 70 extends into the clamping groove 701 and is slidably connected with the cutter 35, wherein, it should be specifically noted that the straight plate 70 can extend to one side of the carrying platform 5, and when one side end surface of the straight plate 70 close to the carrying platform 5 and one side end surface of the cutter 35 close to the carrying platform 5 are located on the same vertical surface, the straight plate 70 can not move to one side of the inclined rail 73 any more, therefore, a limit structure can be arranged in the clamping groove 701 of the straight plate 70, and the limit structure is a conventional design in the field, only the above functions are required to be satisfied, and the detailed description is omitted.

In addition, a mounting groove 557 is formed in one side, close to the alignment clamping assembly 6, of the top end of the lifting plate 551, and a metal roller 558 is rotatably mounted in the mounting groove 557; two sliding plates 556 integrally formed with the lifting plate 551 are fixed at two ends of the lifting plate 551, vertical grooves 59 matched with the sliding plates 556 are formed in two side walls of the rectangular groove 50, and gaps are formed between the metal rollers 558 and one side wall of the rectangular groove 50, which is close to the alignment clamping assembly 6, when the lifting plate 551 is installed in the rectangular groove 50.

In the downward moving process of the two cutters 35, the two straight plates 70 drive the telescopic column 75, the outer wrapping seat 77, the spiral springs 78 and the fixed disc 76 to move downwards, and as the inclined rail 73 is obliquely arranged, the spiral springs 78 gradually shrink in the downward moving process, when the straight plates 70 are clung to the extending plate 552, the spiral springs 78 are in a natural state, and the spiral springs 78 can generate elastic force along with the continuous shrinkage of the spiral springs 78, and after the straight plates 70 move below the extending plate 552, the straight plates 70 extend to one side of the extending plate 552 by utilizing the elastic force of the spiral springs 78, and at the moment, the shearing of pins of electronic components is completed;

after shearing is completed, the first hydraulic cylinder 31 drives the cutter 35 to ascend, so that the two straight plates 70 ascend, the two straight plates 70 drive the extension plate 552 to ascend, at this time, only a pressing plate b needs to be additionally arranged above the pin parts of the electronic components, the edge part of the pressing plate b is guaranteed to be flush with one side wall of the two rectangular grooves 50 close to the alignment clamping assembly 6, and the pin parts of the electronic components are tightly pressed on the top of the mounting seat 54, therefore, in the ascending process of the extension plate 552, the pin parts of the electronic components positioned on the extension plate 552 are driven to move upwards, bending of the pins of the electronic components can be realized by utilizing clearance fit between the metal roller 558 and the rectangular grooves 50, and because the two bearing platforms 5 are symmetrically arranged, the two cutters 35 and the auxiliary lifting mechanism 7 are symmetrically arranged, the pins on two sides of the electronic components can be simultaneously bent.

After the bending operation of the electronic component pins is completed, as the cutter 35 continues to move upwards, the coil spring 78 gradually changes from a compressed state to an extended state, so that a tensile force is applied to the telescopic column 75, when the tensile force is greater than the static friction force between the straight plate 70 and the extension plate 552, the straight plate 70 is rebounded and contracted into the clamping groove 701, at this time, the extension plate 552 falls back into the rectangular groove 50 under the action of gravity of the extension plate 552, so that the next shearing bending operation is performed, and the steps are repeated, so that the electronic component pins can be continuously sheared and bent.

It can be seen from the combination of the first embodiment and the second embodiment that the pin of the electronic component can be sheared in batches, and after the shearing is completed, the pin of the electronic component can be bent, so that the shearing and bending work of the electronic component are integrated, and the working efficiency is greatly improved.
