Description

Technical Field

[0001] The present invention relates to the technical field of box-type transformers, and specifically to a box-type transformer and a processing and crimping device therefor. Background Art

[0002] A box-type transformer is a device used for power transformation and distribution. It usually includes a transformer, switchgear, control equipment, and protection equipment, all installed in a closed box. The box-type transformer is mainly used to reduce high-voltage power supply to low voltage for safe distribution to users; it is widely used in urban and rural power distribution, industrial facilities, commercial buildings, and temporary power use, etc.

[0003] During the production and processing of box-type transformers, in order to ensure reliable and stable electrical connections between various electrical components inside the transformer, it is necessary to crimp and fix the wires or cables in the box-type transformer to reduce the resistance at the connection part, thereby reducing the risks of overheating and short circuit. However, overheating and short circuit phenomena still occur at the crimping terminal positions of existing box-type transformers, resulting in fires and being unable to be processed in time, further causing damage to other electrical components. Secondly, when crimping and fixing the crimping terminals and cables, it is necessary for manual operation to strip, butt, and crimp the two ends of the cable, with slow efficiency. For this reason, we propose a box-type transformer and a processing and crimping device to solve the above problems. Summary of the Invention

A plurality of uniformly distributed material placement grooves 421 are formed on the outer side of the rotating inner cylinder 42. A rotating shaft 422 is fixedly installed in the middle of the rotating inner cylinder 42. The rotating shaft 422 is rotatably installed in the middle of the feeding outer cylinder 41. A first motor 423 is fixedly installed on the outer side of the feeding outer cylinder 41. The driving end of the first motor 423 is fixedly installed with the shaft end of the rotating shaft 422. A feeding through groove 401 is formed at the top of the feeding outer cylinder 41, and a discharging through groove 402 is formed at the bottom of the feeding outer cylinder 41. A stacking guide frame 43 is fixedly installed at the top of the feeding outer cylinder 41. A guide plate 44 is fixedly installed on one side of the bottom of the feeding outer cylinder 41 close to the crimping mechanism 6. During use, a plurality of crimping terminals 12 are stacked in the stacking guide frame 43. The crimping terminal 12 at the lowermost position is sequentially introduced into the material placement groove 421 at the top position through the feeding through groove 401. By controlling the first motor 423 to start, the rotating shaft 422 is driven to drive the rotating inner cylinder 42 to rotate in the feeding outer cylinder 41, and the crimping terminals 12 are sequentially transported to the position of the discharging through groove 402 for automatic feeding of the crimping terminals 12;

[0044] After the automatic peeling of the connecting wire 13 is completed, the horizontal movement of the connecting wire 13 is controlled again. The peeled position of the connecting wire 13 passes through the cutting device 5 and is clamped into the crimping terminal 12 at the lowermost position for automatic docking of the connecting wire 13 and the crimping terminal 12.

A connecting bracket 67 is fixedly installed on the side of the crimping ring cylinder 61 away from the feeding device 4. A positioning disk 68 is fixedly installed on the side of the connecting bracket 67 away from the crimping ring cylinder 61. After the connecting wire 13 and the crimping terminal 12 are automatically butted, continue to control the horizontal movement of the connecting wire 13 and the crimping terminal 12. The connecting wire 13 drives the crimping terminal 12 to move horizontally, so that the crimping terminal 12 is clamped between the plurality of crimping inner blocks 62 in the crimping ring cylinder 61. Subsequently, control the inner ring frame 64 to rotate, drive the plurality of outward protrusions 641 to rotate, so that the outward protrusions 641 contact the inner protrusions 621 at the corresponding positions, thereby controlling the synchronous inward movement of the plurality of crimping inner blocks 62 and compressing the spring 632. The plurality of crimping inner blocks 62 automatically crimp and fix the connecting wire 13 and the crimping terminal 12. After the crimping and fixing is completed, control the inner ring frame 64 to rotate again. The outward protrusions 641 no longer contact the inner protrusions 621 at the corresponding positions, and the spring 632 resets to drive the plurality of crimping inner blocks 62 to separate. Subsequently, control the horizontal reverse movement of the connecting wire 13 and the crimping terminal 12, so that the crimping terminal 12 sequentially disengages from the crimping mechanism 6, the feeding device 4, and the cutting device 5.

[0046] A rotating frame 66 is fixedly installed at the top of the crimping ring cylinder 61. A fixed bracket 664 is vertically installed at the side end of the rotating frame 66.

A first gear 662 is fixedly installed on the outer side of the driving shaft 661. A first toothed ring 65 corresponding to the first gear 662 is provided on the outer wall of the inner ring frame 64. The first gear 662 and the first toothed ring 65 are meshed and connected. A second motor 663 is fixedly installed at the side end of the rotating frame 66. The driving end of the second motor 663 is fixedly installed with the shaft end of the driving shaft 661. By controlling the second motor 663 to start, control the driving shaft 661 to drive the first gear 662 to drive the first toothed ring 65 and the inner ring frame 64 to rotate.

[0047] Working principle: Place the connecting wire 13 between two groups of positioning frames 342. Control the opening of the telescopic cylinder 341 to drive the two sides of the positioning frames 342 to move towards each other to position the connecting wire 13.

[0048] After the connecting wire 13 is positioned, control the opening of the second telescopic rod 35 to drive the corresponding sliding seat 33 to move horizontally, thereby controlling the connecting wire 13 to move automatically horizontally, so that the connecting wire 13 passes through the rotating frame 53 and is placed between two cutting knives 541. Subsequently, until the cutting part of the connecting wire 13 is moved to the position of the two cutting knives 541. Then, control the opening of the first telescopic rod 54 to drive the two groups of cutting knives 541 to move towards each other to automatically cut the outer skin of the connecting wire 13. Subsequently, control the opening of the third motor 533 to drive the corresponding second gear 532 to drive the second toothed ring 531 and the rotating frame 53 to rotate, thereby controlling the two groups of cutting knives 541 to rotate to automatically cut the outer skin of the connecting wire 13 in a circular shape. After the circular cutting is completed, control the connecting wire 13 to move horizontally in the reverse direction again. Under the limiting action of the two groups of cutting knives 541, the circularly cut outer skin automatically detaches from the connecting wire 13, so as to perform automatic stripping of the connecting wire 13. After the stripping is completed, reset the positions of the two groups of cutting knives 541 and the rotating frame 53.

[0049] Stack multiple crimp terminals 12 in the stacking guide frame 43. The crimp terminal 12 at the lowermost position is sequentially introduced into the material placing groove 421 at the top position through the feeding through groove 401. By controlling the opening of the first motor 423 to drive the rotating shaft 422 to drive the inner rotating cylinder 42 to rotate in the outer feeding cylinder 41, the crimp terminals 12 are sequentially transported to the position of the discharging through groove 402 to perform automatic feeding of the crimp terminals 12.

[0050] After the automatic stripping of the connecting wire 13 is completed, control the connecting wire 13 to move horizontally again. The stripped position of the connecting wire 13 passes through the cutting device 5 and is clamped into the crimp terminal 12 at the lowermost position to perform automatic docking of the connecting wire 13 and the crimp terminal 12.

[0051] After the connecting wire 13 and the crimping terminal 12 are automatically butted, continue to control the horizontal movement of the connecting wire 13 and the crimping terminal 12. The connecting wire 13 drives the horizontal movement of the crimping terminal 12, so that the crimping terminal 12 is clamped between multiple crimping inner blocks 62 in the crimping ring cylinder 61. Subsequently, control the second motor 663 to start, and the drive shaft 661 drives the first gear 662 to drive the first toothed ring 65 and the inner ring frame 64 to rotate, driving multiple outward protrusions 641 to rotate, so that the outward protrusions 641 contact the corresponding inward protrusions 621, thereby controlling the synchronous movement of multiple crimping inner blocks 62 toward each other and squeezing the spring 632. Multiple crimping inner blocks 62 automatically crimp and fix the connecting wire 13 and the crimping terminal 12. After the crimping and fixing are completed, control the inner ring frame 64 to rotate again, and the outward protrusions 641 no longer contact the corresponding inward protrusions 621, and the spring 632 resets to drive multiple crimping inner blocks 62 to move away from each other. Subsequently, control the connecting wire 13 and the crimping terminal 12 to move horizontally in the reverse direction, so that the crimping terminal 12 sequentially disengages from the crimping mechanism 6, the feeding device 4, and the cutting device 5;

[0052] Subsequently, control the fourth motor 321 to start, drive the rotating vertical shaft 32 to drive the rotating chassis 31 to rotate horizontally, thereby controlling the connecting wire 13 to rotate horizontally, and rotating the other end of the connecting wire 13 to the position of the cutting device 5 for subsequent operations of automatic peeling, automatic butting, and automatic crimping and fixing.
