Description

Technical Field

[0001] The invention relates to the technical field of accessories processing, in particular to a transformer assembly accessories processing device. Background Art

[0002] The connecting copper busbar is one of the most common assembly parts in power transformers. It is widely used for electrical connections inside transformers due to its excellent electrical conductivity, good thermal conductivity and high mechanical strength.

[0003] In order to facilitate the installation of the copper busbar, the copper busbar is usually processed into a "F" shape (such as Fig.10 As shown), due to the different installation positions of the connecting copper bars, connecting copper bars of different sizes are required. The existing connecting copper bars are generally bent by stamping. The processing method of the connecting copper bars has the following shortcomings: 1. The existing connecting copper bar stamping processing device can only punch out one size of connecting copper bars at a time. When connecting copper bars of different sizes need to be processed, different stamping dies need to be replaced, which affects the processing efficiency of the connecting copper bars. Different stamping processing devices can also be used for processing, but the production cost of the connecting copper bars will increase; 2. After the existing connecting copper bars are produced, the connecting copper bars of the same size are usually packaged together. When connecting copper bars of different sizes are needed, connecting copper bars of different sizes need to be taken from different packages, which is very inconvenient to use.

However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

A hydraulic telescopic cylinder 13 is fixedly installed on the top of the gantry 12, and a movable plate 14 is fixedly connected to the bottom of the telescopic axis of the hydraulic telescopic cylinder 13.

[0036] See also Figure 2 , Figure 3 and Figure 4 The upper mold assembly 22 includes an upper die 221 fixedly connected to the bottom of the upper mold base 21, a clamping plate 222 is slidably installed inside the groove of the upper die 221, and a compression spring 223 is fixedly connected between the top of the clamping plate 222 and the opposite surface of the groove.

[0037] By setting clamping plates 222 of different lengths, connecting copper bars 6 of different lengths can be clamped. When the upper die 221 is stamped downward, the clamping plate 222 can clamp the middle part of the connecting copper bar 6, thereby improving the stability of the connecting copper bar 6 during stamping and preventing the middle part of the connecting copper bar 6 from deforming and warping when the two ends of the connecting copper bar 6 are stamped and bent.

[0038] See also Figure 2 and Figure 3 A slide groove 224 is provided on the side wall of the groove of the upper concave die 221 , and sliders 225 are fixedly connected to the front and rear sides of the clamping plate 222 , and the sliders 225 are installed inside the slide groove 224 for sliding up and down movement.

[0039] By using the slide groove 224 and the slider 225 in coordination, the stability of the upward and downward movement of the pressing plate 222 can be improved, and the pressing plate 222 can be prevented from deflecting.

[0040] See also Figure 1 , Figure 2 and Figure 5 The upper die base 21 is located directly above the lower die base 31 and matches with it, and the stepped surfaces of the upper die base 21 and the lower die base 31 are gradually and equidistantly reduced from left to right.

[0041] By designing the upper die base 21 and the lower die base 31 to be stepped, the stamped connecting copper bars 6 can be arranged in a stepped shape, which facilitates the subsequent stacking of the connecting copper bars 6 and facilitates the integrated overlapping and collecting of the connecting copper bars 6 .

[0042] See also Figure 5 , Figure 6 and Figure 7 The limiting assembly 32 includes a C-shaped seat 321 fixedly connected to the top of the lower die seat 31, and limiting plates 322 are installed on the tops of the two vertical sections of the C-shaped seat 321. The opposite surfaces of the two limiting plates 322 are provided with limiting grooves 323, and the left and right side walls of the limiting grooves 323 are provided with blocking grooves 3231. The interior of the limiting grooves 323 is rotatably connected with a positioning plate 324 through a rotating shaft, and the left and right side walls of the positioning plate 324 are connected with blocking blocks 3241 that match the blocking grooves 3231. A torsion spring 325 for driving the positioning plate 324 to reset is installed on the outside of the rotating shaft, and the two ends of the torsion spring 325 are respectively connected to the limiting plate 322 and the positioning plate 324, and the front and rear length of the positioning plate 324 gradually increases from left to right.

[0043] By using the limiting groove 323 and the positioning plate 324 in coordination, when processing the connecting copper bar 6, the front and rear ends of the connecting copper bar 6 are placed inside the limiting groove 323, which can limit the connecting copper bar 6 and improve the accuracy of processing the connecting copper bar 6. Positioning plates 324 of different lengths are provided to facilitate limiting the connecting copper bars 6 of different lengths. When the upper die 221 is stamping the connecting copper bar 6, the positioning plate 324 can be rotated downward to avoid obstruction to the movement of the upper die 221.

[0044] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 The lower die assembly 33 includes a lower punch 331 installed on the top of the horizontal section of the U-shaped seat 321. Step grooves 332 are provided on the front and rear sides of the lower punch 331. In the lower die assembly 33 arranged from left to right, the front and rear lengths of the lower punch 331 are gradually shortened at equal intervals. The push grooves 34 extend left and right and are horizontally opened on the top of the lower punch 331. The push grooves 34 on adjacent lower punches 331 are connected left and right and the bottoms are flush. The top of the lower punch 331 is flush with the bottom of the limiting plate 322.

[0045] During processing, the connecting copper bus 6 is placed on the top of the lower punch 331, and the upper die 221 is used to punch the connecting copper bus 6 downward, so that the two ends of the connecting copper bus 6 can be pressed onto the stepped groove 332, thereby processing the connecting copper bus 6 into a "J" shape; by setting a pushing groove 34 on the top of the lower punch 331, it is convenient to stack the pushing assembly 43 and move it to the right along the pushing groove 34 to push the formed connecting copper bus 6.

[0046] See also Figure 1 and Figure 8 The circulating conveying assembly 42 includes a transmission shaft 421 rotatably mounted between the tops of the front and rear support seats 41, and a synchronous wheel 422 is symmetrically fixedly sleeved on the outside of the transmission shaft 421, and a synchronous belt 423 is commonly connected to the outside of the synchronous wheels 422 on the same side of the left and right sides for transmission, and the synchronous belt 423 is symmetrically distributed about the lower mold mechanism 3.

[0047] See also Figure 1 , Figure 5 and Figure 8 The stacking pusher assembly 43 includes a connecting rod 431 fixedly connected between the front and rear synchronous belts 423 , and a pusher rod 432 is fixedly connected to the bottom of the connecting rod 431 , and the pusher rod 432 matches the pusher groove 34 .

[0048] The transmission shaft 421 drives the synchronous wheel 422 to rotate, and then the synchronous wheel 422 drives the synchronous belt 423 to rotate, so that the synchronous belt 423 drives the connecting rod 431 and the pushing rod 432 to move to the right, and the pushing rod 432 can move to the right along the pushing groove 34, pushing the connecting copper bar 6 on the lower punch 331 to the right and stacking them together, so as to facilitate the collection of the connecting copper bar 6.

[0049] See also Figure 1 , Figure 8 and Fig. 9 The one-way transmission component 44 includes a hollow gear 441 coaxially rotatably mounted on the outside of one of the transmission shafts 421, a dial 442 located inside the hollow gear 441 is coaxially fixedly sleeved on the outside of the transmission shaft 421, an inner ratchet 443 is arranged on the inner wall of the hollow gear 441, a pawl 444 cooperating with the inner ratchet 443 is rotatably mounted inside the dial 442, an elastic sheet 445 for pushing the pawl 444 to reset is arranged between the pawl 444 and the dial 442, the rack 45 is meshed with the hollow gear 441, and the diameter of the hollow gear 441 is smaller than the diameter of the synchronous wheel 422.

[0050] When the movable plate 14 moves downward, the rack 45 drives the hollow gear 441 to rotate clockwise. At this time, the hollow gear 441 cannot drive the dial 442 to rotate, and the circulating conveying assembly 42 remains stationary. When the movable plate 14 moves upward, the rack 45 drives the hollow gear 441 to rotate counterclockwise, and the inner ratchet 443 is clamped by the pawl 444, so that the dial 442 can rotate with the hollow gear 441, and then the dial 442 drives the transmission shaft 421 to rotate, which can drive the transmission shaft 421 to rotate, so that the circulating conveying assembly 42 operates.

[0051] See also Figure 1 The feeding mechanism 5 is a belt conveying mechanism, and the feeding mechanism 5 is located on the right side of the lower mold mechanism 3. The height of the feeding mechanism 5 is less than or equal to the height of the rightmost lower punch 331.

[0052] The stacked copper connection bars 6 are finally pushed onto the feeding mechanism 5 , and the feeding mechanism 5 is used to feed the copper connection bars 6 to the right.

[0053] See also Figures 1 to 10 When used specifically, step one: place straight connecting copper bars 6 of different lengths on the lower punch 331, place the front and rear ends of the connecting copper bar 6 in the limiting groove 323, and the positioning plate 324 blocks the front and rear ends of the connecting copper bar 6, so that the connecting copper bar 6 is placed symmetrically front and back, and the limiting groove 323 is used to limit the connecting copper bar 6 left and right to improve the accuracy of stamping the connecting copper bar 6.

[0054] Step 2: Use the hydraulic telescopic cylinder 13 to push the movable plate 14 and the upper die mechanism 2 downward to stamp and bend. During stamping, the clamping plate 222 is pressed against the top in the middle of the connecting copper bar 6. The upper die 221 is moved downward to squeeze and bend the front and rear ends of the connecting copper bar 6 onto the stepped groove 332, and the connecting copper bar 6 is processed into a "J" shape. The downward movement of the upper die 221 can push the positioning plate 324 to rotate downward to avoid obstruction to the movement of the upper die 221.

[0055] Step 3: After the stamping is completed, the hydraulic telescopic cylinder 13 drives the movable plate 14 and the upper die mechanism 2 to move upward, so that the upper die 221 is separated from the lower punch 331. At this time, the positioning plate 324 is automatically reset under the push of the torsion spring 325, and the position of the positioning plate 324 can be limited by the cooperation of the retaining groove 3231 and the stop block 3241.

[0056] Step 4: During the upward movement of the movable plate 14, the rack 45 can be driven to move upward together, and the rack 45 is used to drive the hollow gear 441 to rotate counterclockwise, and then the hollow gear 441 drives the dial 442 to rotate counterclockwise through the cooperation of the inner ratchet 443 and the pawl 444, and then the dial 442 drives the transmission shaft 421 to rotate, and then the transmission shaft 421 drives the synchronous wheel 422 and the synchronous belt 423 to rotate, and the synchronous belt 423 drives the connecting rod 431 to move rightward, so that the push rod 432 moves along As the pushing groove 34 slides to the right, the connected copper bars 6 punched on the lower punch 331 are pushed to the right, and the connected copper bars 6 are stacked together one level at a time. Finally, the stacked connected copper bars 6 are pushed to the feeding mechanism 5 and sent out to the right. Since the diameter of the hollow gear 441 is smaller than the diameter of the synchronous wheel 422, the moving speed of the pushing rod 432 is greater than the moving speed of the movable plate 14. When the movable plate 14 moves upward to its original position, the pushing rod 432 just returns to the initial position on the left side of the lower mold mechanism 3.
