Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal stamping dies, in particular to a side punching die for processing arc workpieces. Background Art

[0002] During the arc workpiece forming process, due to its unique shape, the workpiece can easily pop out due to uneven force. The popping force of different batches of materials is inconsistent, resulting in inaccurate punching position. The equipment is also prone to wear or failure after long-term use. The pits and wear of the mold will also make it impossible for the workpiece to fit completely when in contact. The uneven force during stamping makes the arc punching easy to loosen. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a side punching die for processing arc workpieces. The arc of the product is compacted by a circular pressing block and then side punching is performed, thereby ensuring the accurate position of the hole on the product and not being affected by different batches of materials.

[0004] In order to achieve the above-mentioned purpose, a side punching die for processing arc workpieces is designed, including an upper die base and a lower die base corresponding to the upper die base, two upper die slides and guide pillars are respectively provided on the left and right sides of the lower surface of the upper die base, a circular pressing block is provided between the two upper die slides on the same side, the upper side of the circular pressing block is connected to the upper die base, a lower die base is provided below the upper die base, two lower die slides and guide sleeves cooperating with the upper die slide and guide pillars are respectively provided on the left and right sides of the upper surface of the lower die base, the upper die slide and the lower die slide are both provided with inclined surfaces, a nitrogen spring is provided between the lower die slide and the lower die base, the inner side of the lower die slide is connected to the pressure plate, a limit block is provided on the outer side of the lower die slide, and a fixed seat is provided between the two lower die slides on the same side.

[0005] The upper portion of the fixing seat is connected to the product, and the upper surface of the fixing seat matches the lower surface of the product.

[0006] The lower die base is connected to the lower pad and the lower supporting plate in sequence.

[0007] The left and right sides of the lower die slide block are slidably connected to the guide blocks.

[0008] Buffer plates are provided at the contact points between the upper die slide block and the lower die slide block during mold closing, and at the contact points between the upper die slide block and the limit block during mold closing.

[0009] The upper die slide block and the upper die base are connected through pins, as are the lower die slide block and the lower die base.

[0010] Compared with the prior art, the processed product of the utility model is less affected by the mold precision and quality, and the finished product is obtained by the process of first fixing and then punching the pressing block that fits the arc, which has the advantages of simple structure, strong practicality and cost saving.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, two upper die slides 2 and guide pillars 10 are respectively provided on the left and right sides of the lower surface of the upper die base 1, and a circular pressing block 3 is provided between the two upper die slides 2 on the same side. The structure of the circular pressing block 3 matches the product 9. The upper side of the circular pressing block 3 is connected to the upper die base 1, and a lower die base 6 is provided below the upper die base 1. Two lower die slides 4 and guide sleeves 11 that match the upper die slide 2 and guide pillars 10 are respectively provided on the left and right sides of the upper surface of the lower die base 6. Both the upper die slide 2 and the lower die slide 4 are provided with inclined surfaces 18. When the mold is closed, the upper die slide 2 squeezes the lower die slide 4 from the outside, and the inclined surfaces 18 of the upper die slide 2 and the lower die slide 4 contact. A nitrogen spring 12 is provided between the lower die slide 4 and the lower die base 6. The nitrogen spring 12 plays a buffering role. The inner side of the lower die slide 4 is connected to the pressure plate 14, and a limit block 5 is provided on the outer side of the lower die slide 4. A fixed seat 13 is provided between the two lower die slides 4 on the same side.

[0020] The upper part of the fixing seat 13 is connected to the product 9, and the upper surface of the fixing seat 13 cooperates with the lower surface of the product 9. The fixing seat 13 plays a role in fixing the product 9. When the mold is closed, the arc-shaped product 9 is fixed in the upper and lower directions through the cooperation of the fixing seat 13 and the circular pressing block 3.

[0021] The lower die base 6 is connected to the lower pad 7 and the lower supporting plate 8 in sequence.

[0022] The left and right sides of the lower die slide block 4 are connected to guide blocks 15 , which have a guiding effect on the lower die slide block 4 .

[0023] A buffer plate 16 is provided at the contact point between the upper die slider 2 and the lower die slider 4 during mold closing, and at the contact point between the upper die slider 2 and the limit block 5 during mold closing. The buffer plate 16 reduces wear between parts during the extrusion process.

[0024] The upper die slider 2 and the upper die base 1 , as well as the lower die slider 4 and the lower die base 6 are connected via pins 17 .

[0025] During the specific implementation process, the product 9 is placed on the fixed seat 13, and the product 9 and the fixed seat 13 are fixed by shape matching. The upper mold seat 1 is pressed down, and the guide column 10 first contacts the guide sleeve 11 to prevent the downward pressure from deflecting. The upper mold slider 2 contacts the lower mold slider 4, and the extrusion force is buffered by the buffer plate 16. During the extrusion process, the upper mold slider 2 is subjected to the inclined surface reaction force of the lower mold slider 4, so that the vertical downward extrusion force is transmitted 90° into a horizontal force and moves outward until the upper mold slider 2 is restricted by the limit block 5. The upper mold slider 2 and the limit block 5 are provided with a buffer plate 16 to buffer the force. The lower mold slider 4 is subjected to the inclined surface reaction force of the upper mold slider 2, so that the vertical downward extrusion force is transmitted 90°. The guide block 15 The movement direction of the lower die slider 4 is limited, and the guide block 15 makes the lower die slider 4 move inward. At this time, the nitrogen spring 12 at the bottom of the lower die slider 4 is squeezed, which plays a buffering role. The left and right displacement positions of the product 9 are limited from both sides on both sides of the lower die slider 4. The upper die seat 1 continues to press down, and the circular pressing block 3 is pressed down and contacts the fixed seat 13 to compact the product 9 from above. At this time, punching the product 9 from the side can ensure that the punching position of the product 9 is determined. After the product 9 is processed, the upper die seat 1 moves upward, and the nitrogen spring 12 on the lower side of the lower die slider 4 rebounds to make the lower die slider 4 return to its original position, and the processing process is completed. The utility model has a simple structure, strong practicality and cost savings.
