Description
技术领域Technical Field
本发明涉及冲裁机构的送料装置，具体是一种用于厚板冲裁的送料装置。The invention relates to a feeding device of a punching mechanism, in particular to a feeding device used for punching thick plates.
背景技术Background Art
冲裁是利用冲模使部分材料或工序件与另一部分材料、工(序)件或废料分离的一种冲压工序。冲裁是剪切、落料、冲孔、冲缺、冲槽、剖切、凿切、切边、切舌、切开、整修等分离工序的总称。Blanking is a stamping process that uses a die to separate part of the material or process parts from another part of the material, process (process) parts or waste. Blanking is a general term for separation processes such as shearing, blanking, punching, notching, notching, cutting, chiseling, trimming, tongue cutting, cutting, and trimming.
我公司现有产品中，厚板(≥5mm)冲裁件较多，所用坯料为长4～5米的钢带板，其体积较大、质量较重。为减少送料阻力、降低劳动强度，通常需在冲裁模具的下模座上附带送料辊道。Among our company's existing products, there are many thick plate (≥5mm) blanking parts. The blanks used are 4-5 meters long steel strips, which are large in size and heavy in weight. In order to reduce feeding resistance and labor intensity, it is usually necessary to attach a feeding roller to the lower die seat of the blanking die.
但厚板坯料的刚性较大，模具工作时的冲裁力会经由坯料对辊道产生反复的冲击力，故模具上附带的送料辊道易出现辊子表面受损、辊轴变形等问题，最终导致送料困难，影响正常的生产效率。However, the rigidity of thick plate blanks is relatively large, and the blanking force of the mold during operation will produce repeated impact force on the rollers through the blanks. Therefore, the feeding rollers attached to the mold are prone to problems such as roller surface damage and roller shaft deformation, which ultimately lead to difficulties in feeding and affect normal production efficiency.

In the embodiment of the present invention, a feeding device for thick plate blanking includes a mounting plate 14, a side guide block 4, a roller support 5 and a roller 6. The mounting plate 14 is fixedly connected to the blanking die body 3 by screws and pins. The side guide block 4 is provided with a pair and is installed on both sides of the upper end surface of the mounting plate 14. The roller support 5 is arranged on the upper end surface of the mounting plate 14. The side guide block 4 and the roller support 5 are fixedly connected to the mounting plate 14 by screws and pins. The side guide blocks 4 on both sides are symmetrically arranged. The roller support 5 is located between the side guide blocks 4 on both sides. A limiting end surface 501 is provided on the roller support 5. Two rollers 6 are provided and installed on both sides of the roller support 5. A roller shaft 12 is provided inside the roller 6. The roller shaft 12 and the roller 6 are movably connected through a bearing 7. A retaining ring 8 is provided on the roller shaft 12 outside the bearing 7. The end faces of both sides of the roller 6 are detachably connected with a cover 9. The inner ring of the cover 9 is connected to the roller shaft 12 for relative rotation. Vertical mounting holes are provided at both ends of the roller shaft 12. The roller shaft 12 is connected to the roller support 5 for sliding up and down through a limit screw 10. A bushing 11 is provided between the mounting hole of the roller shaft 12 and the limit screw 10. A plurality of disc springs 13 stacked in positive and negative directions are sleeved on the limit screw 10. The disc spring 13 is located between the roller support 5 and the roller shaft 12.
本发明结构新颖，运行稳定，本发明在使用时，当毛坯料1被送入模具时，侧导向块4可以对其进行侧向定位，同时两个辊子6从毛坯板料1的下方对其进行支撑，此时的辊子6在限位螺钉10的限制下，可保证其送料高度与模具的承料高度一致，故毛坯板料1的送进和定位操作均能较轻松的完成；在模具开始冲裁前，毛坯板料1与辊道支座5顶部的限位端面501预留了约2mm的间隙。在模具进行冲裁时，毛坯板料1对辊子产生了向下的冲击力，则碟形弹簧13会受力压缩并产生缓冲作用，辊轴12向下滑动，辊子6随之下沉，避免了毛坯板料1与辊子6间的刚性冲击，如果此时毛坯板料1的震动和冲击过大，则辊道支座5顶部的限位端面501会对毛坯板料1的位移幅度进行限制，代替辊子6承受毛坯板料1的冲击力，同时防止了碟形弹簧13的压缩量超过设计范围，进一步延长该送料装置的使用寿命；冲击结束后，碟形弹簧13释放出弹性力，辊轴12和辊子6回到原始高度，则此时可以继续送进毛坯板料1，开始下一次的模具冲裁操作。由于碟形弹簧13的结构紧凑且支座5的限位端面501对辊子6的下沉量进行了限制，所以辊子6上浮时的位移较小、回位迅速，确保了本装置在模具连续冲裁时可以高效、稳定的工作。The present invention has a novel structure and stable operation. When the present invention is in use, when the blank 1 is fed into the mold, the side guide block 4 can laterally position it, and at the same time, the two rollers 6 support the blank sheet 1 from below. At this time, the roller 6 is limited by the limit screw 10 to ensure that its feeding height is consistent with the material receiving height of the mold, so the feeding and positioning operations of the blank sheet 1 can be completed more easily; before the mold starts punching, a gap of about 2 mm is reserved between the blank sheet 1 and the limit end face 501 at the top of the roller support 5. When the die is punching, the blank sheet 1 generates a downward impact force on the roller, then the disc spring 13 will be compressed and produce a buffering effect, the roller shaft 12 slides downward, and the roller 6 sinks accordingly, avoiding the rigid impact between the blank sheet 1 and the roller 6. If the vibration and impact of the blank sheet 1 are too large at this time, the limiting end face 501 on the top of the roller support 5 will limit the displacement amplitude of the blank sheet 1, replacing the roller 6 to bear the impact force of the blank sheet 1, and at the same time prevent the compression of the disc spring 13 from exceeding the design range, further extending the service life of the feeding device; after the impact is over, the disc spring 13 releases the elastic force, the roller shaft 12 and the roller 6 return to the original height, then the blank sheet 1 can continue to be fed in, and the next die punching operation can be started. Since the disc spring 13 has a compact structure and the limiting end surface 501 of the support 5 limits the sinking amount of the roller 6, the roller 6 has a small displacement when floating and returns quickly, ensuring that the device can work efficiently and stably during continuous die punching.
