Description

Technical Field

[0001] The invention relates to the technical field of transformer iron core production, and in particular to an iron core lamination device. Background Art

[0002] EI transformer is a type of transformer, which is defined by the shape of the core. Because the core of EI transformer is composed of "E" type sheets and "I" type sheets stacked together, it is called EI transformer. In the production process of EI transformer, automatic lamination equipment can automatically position and fix silicon steel sheets, which can improve the processing and production efficiency of transformer core. However, these automatic stacking equipment are currently only applicable to small and medium-sized transformer core production lines. For large cores, manual stacking and installation are often still required. This method not only has high labor costs, but also requires lifting equipment to adjust the position of each silicon steel sheet multiple times to meet the positioning requirements, so its production efficiency is not high. Summary of the invention

[0003] The present invention provides an iron core lamination device. Compared with manual iron core stacking and forming, the device not only improves the stacking efficiency of silicon steel sheets, but also improves the stacking accuracy by utilizing tooling, does not require manual position adjustment, and avoids the occurrence of industrial accidents such as steel plate pinching hands, thereby reducing the production cost of transformer iron cores and improving product quality and production efficiency.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a core lamination equipment, comprising: a pedestal, a rotating table is provided in the center of the top of the pedestal, a stacking tool is provided on the top of the rotating table, and a reduction motor is provided on the rotating table; a pair of material storage troughs, two of which are respectively arranged on the top of the pedestal and correspond to the opposite sides of the rotating table; a gantry, the gantry is fixedly arranged on the top of the pedestal, and the gantry is provided with a horizontal lifting beam corresponding to the rotating table and the two material storage troughs, and a lifting motor driving the lifting beam; a pair of reciprocating sliders, each of which is arranged at the bottom of the lifting beam, and reciprocates horizontally between the corresponding material storage trough and the rotating table, and a transfer motor driving the two reciprocating sliders is provided at the bottom of the lifting beam; a telescopic suction cup, the telescopic suction cup is arranged in multiples and distributed at the bottom of each of the reciprocating sliders, and each of the telescopic suction cups is connected to a vacuum pump through a vacuum tube and a control valve; a controller, the reduction motor, the lifting motor, the transfer motor and the control valve are electrically connected to the controller respectively.

[0005] Preferably, an encoder is provided between the rotating table and the base, and the encoder is electrically connected to the controller; the two material storage troughs are composed of a first material trough and a second material trough, the first material trough is used to stack and stack a number of I-type silicon steel sheets, and the second material trough is used to stack and stack a number of E-type silicon steel sheets.

[0006] Preferably, tracks are provided on both sides of the lifting beam, and the top of each reciprocating slider cooperates with the track through a hanging wheel; the transfer motor is a double-output shaft motor, and splines are provided at two output ends, and the reciprocating screw of each reciprocating slider is connected to the corresponding output end through a spline.

[0007] Preferably, the gantry includes columns vertically arranged at both ends of the pedestal, each of the columns is provided with a synchronous chain, the sprockets at the top of the two synchronous chains are mutually transmitted through a synchronous shaft, and one end of the synchronous shaft is connected to the output shaft of the lifting motor; the two ends of the lifting beam cooperate with the corresponding columns through a lifting slider, and each of the lifting sliders is connected to the corresponding synchronous chain; the column is provided with a travel switch, and the travel switch is electrically connected to the controller.

[0008] Preferably, both ends of the top of the pedestal are respectively provided with setting slide rails along the diameter direction of the rotating table, each of the setting slide rails is respectively matched with a positioning slide, and the first material trough and the second material trough are respectively adapted on the top of the corresponding positioning slide.

[0009] Preferably, an adjusting slide rail is provided at the bottom of each reciprocating slider, an adjusting slide table is provided at the bottom of the adjusting slide rail, and the telescopic suction cup is connected to the corresponding bottom of the adjusting slide table through a longitudinally arranged spring telescopic rod.

[0010] The beneficial effect of the present invention is that the reduction motor, under the action of the controller, makes the rotating table work intermittently at a pause interval of 180 degrees. During this process, the two reciprocating sliders continuously reciprocate above the first material trough, the second material trough and the rotating table, and under the action of the telescopic suction cup, the I-type silicon steel sheets and the E-type silicon steel sheets on the first material trough and the second material trough are picked up and stacked in the stacking tooling of the rotating table. Every time a layer of material is stacked, the rotating table rotates 180 degrees, thereby realizing the alternating stacking and stacking of the I-type silicon steel sheets and the E-type silicon steel sheets in the stacking tooling, and forming the completed form of the transformer core. Compared with manual iron core stacking and forming, the equipment not only improves the stacking efficiency of silicon steel sheets, but also improves the stacking accuracy by using the tooling, does not require manual position adjustment, and avoids the occurrence of industrial accidents such as steel plate pinching, thereby reducing the production cost of the transformer core and improving product quality and production efficiency. The encoder provides a precise rotation angle for the rotating table, and realizes start-stop and slow motion according to the control, so as to avoid the problem of shaking and offset of the iron core after stacking due to excessive impact force; the two storage troughs are composed of a first trough and a second trough, which ensures that the I-type silicon steel sheets and the E-type silicon steel sheets have a unified initial position, so that the telescopic suction cup can move them accurately to the set position. The double-output shaft motor ensures the synchronous motion characteristics of the two reciprocating sliders. In addition, the combination angle setting of the reciprocating screw is realized through the spline to meet the synchronous or asynchronous working setting of the two reciprocating sliders, which can effectively improve the collision problem of I-type silicon steel sheets and E-type silicon steel sheets during the stacking process. The lifting motor drives the two sprockets together through the synchronous shaft, so that the lifting beam can be lifted and lowered horizontally under the action of the synchronous chain. During the stacking process of silicon steel sheets, the travel switch causes the lifting beam to drop to a uniform height, and the telescopic suction cup is used to adapt to the height of the continuously stacked cores, so as to achieve greater stacking pressure for the cores in the later stage of stacking, and to ensure that the stacked cores can obtain higher stacking pressure in the later stage of stacking, and avoid the shaking problem caused by the elasticity of the lower silicon steel sheet, so as to ensure that the position of the I-type silicon steel sheet and the E-type silicon steel sheet in the stacking is more accurate. By adjusting and setting the position of the positioning slide and the adjustment slide, the stacking spacing of the silicon steel sheets can be adjusted to meet the stacking work of transformer cores of different specifications. The spring telescopic rod uses its own telescopic elasticity to ensure that the telescopic suction cup can accurately absorb the silicon steel sheet and stably place it in the stacking tooling.

[0018] Among them, an encoder 11 is provided between the rotating table 5 and the base 1, and the encoder 11 is electrically connected to the controller, so as to provide a precise rotation angle for the rotating table 5, and realize start-stop slow movement according to the control, so as to avoid the problem of shaking and deviation of the iron core after stacking due to excessive impact force; the two storage troughs 4 are composed of a first trough and a second trough, the first trough is used for stacking and stacking a number of I-type silicon steel sheets, and the second trough is used for stacking and stacking a number of E-type silicon steel sheets, and ensure that the I-type silicon steel sheets and the E-type silicon steel sheets have a unified initial position, so that the telescopic suction cup 10 can move it accurately to the set position.
