The machine platform 1 is provided with a shaping pressure platform 4 which is respectively connected to the feed line 2 and the discharge line 3 end to end. The shaping pressure platform 4 is divided into a plurality of workstations, each of which is equipped with a lateral extrusion shaping cylinder 5 and a vertical extrusion shaping cylinder 6. The shaping pressure platform 4 is provided with a transfer station 7 between the workstations for separating the lateral extrusion shaping cylinder 5 and the vertical extrusion shaping cylinder 6. A pin test row 8 is arranged on the discharge line 3.

[0025] Among them, the machine platform 1 is provided with an upstream slide 11 driven by an X-axis cylinder 9 and a Z-axis cylinder 10, the workstations include a first workstation 12, and the upstream slide 11 is provided with an upstream air claw 13 that equidistantly spans the feed line 2 and travels back and forth between the first workstation 12 and the transfer station 7.

[0026] Furthermore, the upstream air gripper 13 includes a first transport air gripper 14 , and the first transport air gripper 14 connects the feed line 2 and the first workstation 12 .

[0027] Furthermore, the lateral extrusion molding cylinder 5 is arranged at the first workstation 12, the upstream air claw 13 includes an auxiliary positioning air claw 15, the lateral extrusion molding cylinder 5 is composed of a dual-axis slide cylinder 16 and a pair of silicon steel sheet molding blocks 17, the silicon steel sheet molding blocks 17 are respectively connected to the two ends of the dual-axis slide cylinder 16 through an adapter plate 18, the silicon steel sheet molding blocks 17 are opposite to each other in the horizontal direction and matched above the dual-axis slide cylinder 16 and on both sides of the auxiliary positioning air claw 15, and the auxiliary positioning air claw 15 connects the first workstation 12 and the transfer station 7.

[0028] Furthermore, the workstation includes a number of equidistantly arranged second workstations 19, and a plurality of downstream air grippers 30 are arranged on the outside of all the second workstations 19, which travel back and forth between the adjacent second workstations 19 and are equidistantly connected to the transfer station 7 and the discharge line 3 in both directions. The downstream air grippers 30 are equidistantly arranged on the XY-axis cylinder slide 31 provided on the machine 1.

[0029] Furthermore, an elevated platform 32 is erected above each second workstation 19 , and a plurality of synchronous guide column lifting platforms 34 driven by downward pressure cylinders 33 are suspended under the elevated platform 32 , and silicon steel sheet shaping blocks 17 are mounted under the synchronous guide column lifting platforms 34 .

[0030] Furthermore, the discharging line 3 is arranged along the X-axis direction, the pin test row 8 is provided with a plurality of probes 35 arranged along the Y-axis direction, and a Y-axis slide cylinder 36 connected to the pin test row 8 is mounted on the machine 1.

[0031] Furthermore, the discharge line 3 is arranged along the X-axis direction, the pin test row 8 is provided with a plurality of pin sockets 37 arranged along the Z-axis direction, and a Z-axis slide cylinder 38 connected to the pin test row 8 is mounted on the machine 1, and the Z-axis slide cylinder 38 is mounted on a Z-axis manual fine-tuning platform 39.

[0032] Furthermore, an NG line 40 is set up parallel to the discharging line 3, a blocking cylinder 41 is horizontally arranged on the discharging line 3, and a sorting claw 42 is arranged between the discharging line 3 and the NG line 40 and docked on the upstream side of the blocking cylinder 41, and the sorting claw 42 is mounted on the YZ two-axis cylinder slide 43.

[0033] like Figure 1 As shown, the preassembled transformer flows from the feed line 2 to the shaping pressure platform 4, and after being shaped on the shaping pressure platform 4, it is tested for performance by the pin test row 8 on the downstream side, and finally discharged from the discharge line 3. Among them, the main part of the transformer is composed of a large number of uneven silicon steel sheets stacked on each other. The stacked silicon steel sheets form a hexahedron, in which the four faces (a pair of A faces and a pair of B faces) that constitute the layer structure need to be stacked neatly under the action of cylinder pressure. The two A faces are shaped for the first time, and the two B faces are shaped for the second time. Among them, the shaping of the B faces can be repeated for multiple times, so that the edges of the silicon steel sheets are completely aligned.

[0034] like Figure 2 As shown, the connection between the feed line 2 and the first workstation 12 is achieved through the X-axis cylinder 9 and the Z-axis cylinder 10 on the upstream slide 11.

[0035] Combination Figure 3 As shown in the figure, the first transporting air gripper 14 is used to transport the transformer from the feed line 2 to the first workstation 12, and the auxiliary positioning air gripper 15 is used to grab the transformer at the first workstation 12 to the Figure 4 On the lateral extrusion shaping cylinder 5 shown.

At this time, the uneven silicon steel sheet A surface on the transformer is pressed by the silicon steel sheet shaping blocks 17, and the A surface is aligned under the clamping pressure of the silicon steel sheet shaping blocks 17.

[0037] After the lateral extrusion shaping cylinder 5 is finished, the auxiliary positioning claw 15 continues to transport the transformer to the Figure 2 Transfer station 7 is shown.

[0038] like Figure 2As shown, the workstation includes three second workstations 19, each of which is matched with a set of vertical extrusion shaping cylinders 6. Figure 5 Driven by the XY-axis cylinder slide 31 shown, the downstream air claw 30 continuously transports the transformer at the transfer station 7 to the second workstation 19 in the downstream direction. Each transformer will stop once at each second workstation 19 under the clamping of the downstream air claw 30, and will be subjected to the downward pressing and shaping treatment of the vertical extrusion and shaping cylinder 6 three times in total.

[0039] like Figure 6 The downward pressure cylinder 33 shown drives the silicon steel sheet shaping block 17 under the synchronous guide column lifting platform 34 to press one B surface of the silicon steel sheet stack, and the other B surface contacts the shaping pressure bearing platform 4. After repeated three downward pressure shaping, the silicon steel sheet shaping is completed.

[0040] like Figure 7 As shown, depending on the different circuit structures of the transformer, the transformer is tested by contacting with a probe 35 or by crimping with a pin socket 37. After the test is completed, an OK or NG signal is given, and the sorting cylinder selects the transformer with the corresponding signal to the NG line 40 or the discharge line 3.
