The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0022] As Figs. 1 to 3 As shown in a transformer flat foot machine, characterized in that, including bottom plate 1, the bottom plate 1 is equipped with the communicating hole of up and down intercommunication, the bottom plate 1 upper side is equipped with fixed jig 2, the fixed jig 2 is equipped with containing cavity 21 corresponding with bottom plate 1 communicating hole, the fixed jig 2 upper side is equipped with the upper through hole in communication with the outside, the upper through hole position is equipped with positioning jig 3, for placing the transformer to be processed, the positioning jig 3 both sides are equipped with clamping structure 4, for clamping the transformer, the containing cavity 21 is equipped with flat foot structure 5, the flat foot structure 5 includes moving block 51, the moving block 51 moves horizontally, and the pin of the transformer to be processed is bent outward to the horizontal state.

[0023] The transformer to be processed is placed in the position of the positioning jig 3, and then clamped under the action of the clamping structure 4. The pins of the transformer are directly bent outward by the moving block 51 of the flat foot structure 5, thereby completing the bending of the transformer pins. At this time, the bending work is automatically completed after the transformer is placed, and the bending efficiency is high.

[0024] During the bending process, the transformer pins need to be fixed, i.e. the transformer needs to be fixed by the positioning jig 3. In this embodiment, the upper side of the fixing jig 2 is provided with a longitudinal positioning groove 11, and the positioning jig 3 is fixed in the position of the longitudinal positioning groove 11 by a fastener. Further, the positioning jig 3 includes a positioning portion 31, which is rectangular in cross section. The width of the positioning portion 31 is adapted to the inner side spacing of the transformer pins to be processed. The longitudinal positioning groove 11 is arranged on the upper side of the fixing jig 2, and then the positioning jig 3 is fixed in the longitudinal positioning groove 11 by a fastener. In this way, the positioning jig 3 (positioning portion 31) is located at the upper side of the receiving cavity 21 of the fixing jig 2 and in the middle of the upper through hole. After the transformer is placed on the upper side of the positioning portion 31, the pins on both sides of the transformer are located on both sides of the positioning portion 31.

[0025] During the bending of the transformer pins, the transformer needs to be clamped and fixed. Therefore, at this time, the clamping structure 4 includes a clamping cylinder 41, the piston rod of the clamping cylinder 41 is connected with a clamping block 42, the upper side of the fixing jig 2 is provided with a transverse positioning groove, and the clamping block 42 moves transversely in the transverse positioning groove. Under the action of the clamping cylinder 41, the clamping block 42 moves transversely in the transverse positioning groove, thereby clamping the transformer.

[0026] Further, the clamping block 42 includes a clamping portion 421 with the same height as the positioning portion 31, the upper side of the transverse positioning groove is provided with a limiting block 12, and the limiting block 12 is fixed on the upper side of the fixing jig 2 for transverse movement of the clamping block 42 in the transverse positioning groove. At this time, the clamping portion 421 has the same height as the positioning portion 31, so that the pins at the side edge position of the positioning portion 31 can be clamped, thereby clamping the whole transformer.

[0027] Of course, at this time, after the clamping portion 421 and the positioning portion 31 clamp the pins, in order not to affect the bending requirement of the pins, the thickness of the clamping portion 421 and the positioning portion 31 is small at this time, so as not to affect the bending of the pins.

[0028] After the transformer is fixed, the moving blocks 51 of the flat foot structure 5 need to move outward to bend the pins. In this embodiment, the flat foot structure 5 further comprises guide rods 52 fixed in the lateral through holes of the fixing jig 2, the moving blocks 51 are sleeved on the outer sides of the guide rods 52, the inner inclined surfaces 511 are arranged on the opposite inner sides of the moving blocks 51, the flat foot cylinder 53 is arranged on the lower side of the bottom plate 1, the piston rod of the flat foot cylinder 53 is connected with the top block 54 moving up and down, the top block 54 is located on the inner side of the inner inclined surfaces 511 of the two moving blocks 51, and the moving blocks 51 move laterally along the guide rods 52 when the top block 54 moves up and down. The guide rods 52 are fixed in the lateral through holes of the fixing jig 2, the lateral through holes are arranged through the accommodating cavity 21, the moving blocks 51 are sleeved on the outer sides of the guide rods 52, so that the moving blocks 51 can move linearly in the lateral movement process, thereby ensuring that the transformer pins are in a linear state after being bent. Under the action of the flat foot cylinder 53, the top block 54 moves up and down, the top block 54 acts on the inner inclined surfaces 511 of the moving blocks 51, so that the moving blocks 51 move outward along the guide rods 52 in the upward movement process of the top block 54, thereby bending the transformer pins outward.

[0029] The pins are bent and deformed by moving the moving blocks 51 outward, and when the transformer is placed in the positioning part 31, the moving blocks 51 need to act on the inner side of the pin position. Therefore, in this embodiment, the upper side of the moving block 51 is provided with an abutting part 512, the side of the abutting part 512 is provided with an upper inclined surface, the abutting parts 512 are located on the lower side of the positioning part 31 of the positioning jig 3 when the two moving blocks 51 are close to each other, and the width of the two abutting parts 512 when they are close to each other is not greater than the width of the positioning part 31. The abutting part 512 is located at the top position of the moving block 51, and when the top block 54 does not move upward, the abutting part 512 is located at the lower side of the positioning part 31 of the positioning jig 3. Therefore, after the transformer is placed on the upper side of the positioning part 31, the pins of the transformer are located on the outer side of the positioning part 31 and the abutting part 512 of the moving plate, and the abutting part 512 of the moving plate can act on the pins after moving outward, thereby bending the pins.

[0030] At this time, after the external force acting on the moving blocks 51 is removed, in order to enable the moving blocks 51 to move to the middle position of the accommodating cavity 21, at this time, springs 55 are sleeved on the outer sides of the guide rods 52, the springs 55 are located between the moving blocks 51 and the side walls of the accommodating cavity 21, and are used to move the two moving blocks 51 towards the middle position of the accommodating cavity 21. The spring 55 is in a compressed state, and under the action of the spring 55, the moving block 51 moves towards the middle position of the accommodating cavity 21, so that the moving block 51 can be in the middle position, thereby ensuring the normal placement of the transformer.

[0031] Since the two moving blocks 51 move towards two directions respectively, in order to ensure the stability of the movement, in the embodiment, the top block 54 is tapered on the upper side and is provided with two outer inclined surfaces corresponding to the inner inclined surfaces of the moving blocks 51, and the outer inclined surfaces of the top block 54 abut against the inner inclined surfaces 511 of the moving blocks 51 when the top block 54 moves up and down. In this way, when the top block 54 moves up and down, the moving blocks 51 can move more stably through the contact of the inclined surfaces.

[0032] Since the moving blocks 51 are sleeved outside the guide rods 52, the guide rods 52 are also located at the positions of the inner inclined surfaces 511 of the moving blocks 51, and in order to avoid the interference between the top block 54 and the guide rods 52 when the top block 54 moves up and affect the movement of the top block 54, in the embodiment, the upper side of the top block 54 is provided with an avoiding groove 541 extending to the top of the top block 54 and communicating with the outside, and the avoiding groove 541 is clamped in the inner and outer sides of the guide rods 52 when the top block 54 moves up. The avoiding groove 541 is opposite to the guide rods 52, and the top block 54 can be clamped into the guide rods 52 at the position of the avoiding groove 541 when the top block 54 moves up, so as to ensure that the moving distance of the top block 54 is larger, and further ensure the lateral moving distance of the moving blocks 51.

[0033] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, it should be considered that the combinations are within the scope of the present application.

[0034] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
