Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a continuous stamping die with waste material blowing function. Background Technology
[0002] like Figure 1 As shown, two adjacent products 2 are connected by waste material 1. The traditional method is to remove the waste material manually. However, this method is inefficient and cannot guarantee the uniformity of product quality (sometimes too much waste material is removed, resulting in incomplete products, and sometimes too little waste material is removed, requiring further processing), which increases the amount of rework.
[0003] To address the aforementioned problems, progressive stamping dies are used to remove waste material from the product. However, traditional progressive stamping dies are only suitable for situations where the waste material is at the end of the product or is in large pieces. For example... Figure 2 As shown, the shape of product 2 is quite special, and the waste material is located between two adjacent products. The inward curve of the two sides of the product results in a narrow space. Using ordinary methods, the waste material is likely to fall into the waste material hole inaccurately and is very likely to fall onto the product, causing product deformation or even mold explosion. Summary of the Invention
[0004] To overcome the shortcomings of the prior art, this utility model provides a continuous stamping die with waste blowing function. The blow-blowing channel is opened in the die cavity to assist in blowing the waste material out of the die.
[0005] To achieve the above objectives, a continuous stamping die with waste material blowing is designed, comprising an upper die base and a lower die base. The upper die base has one end of an upper pad connected to its bottom, and the other end of the upper pad connected to an upper fixed plate. A pressure plate is located below the upper fixed plate. One end of a punching punch is connected to the bottom of the upper pad, and the other end of the punching punch passes through both the upper fixed plate and the pressure plate. A lower lifting plate is located above the lower die base. Several die fixing support blocks are connected to the lower die base. The bottom of each die fixing support block is connected to the lower die base, and the top of each die fixing support block passes through the lower lifting plate and is located above it. The bottom of a die fixing seat is connected to the lower lifting plate located on one side of the die fixing support block. A punching die is embedded in the top of the die fixing seat, and the punching die has a punching opening. An air blowing channel is provided inside the die fixing seat.
[0006] The position of the blanking opening on the blanking die corresponds to the end of the blanking punch. The bottom of the blanking opening is connected to the blanking channel, and one side of the blanking channel is connected to the air outlet of the air blowing channel.
[0007] The air blowing channel has an L-shaped pipe structure. The air blowing outlet of the air blowing channel is connected to one side of the material feeding channel, and the air blowing inlet of the air blowing channel extends out of the lower part of the die fixing seat.
[0008] The lower lifting plate and the lower mold base are respectively provided with air pipe channels, and air inlet pipes are provided in the air pipe channels. The air inlet pipes lead from the air pipe channels in the lower lifting plate and the lower mold base to the air inlet of the air blowing channel.
[0009] An air inlet connector is fitted at the head of the air inlet pipe.
[0010] A guide post is provided on one side of the upper pad, upper fixing plate, and pressure plate. The top of the guide post is connected to the upper mold base with connecting bolts.
[0011] A guide sleeve is provided on one side of the lower lifting plate. The lower part of the guide sleeve is embedded in the lower mold base, and the guide sleeve and the guide post cooperate with each other.
[0012] The aforementioned die fixing seat support block is provided with at least two.
[0013] Compared with the prior art, this utility model provides a continuous stamping die with waste blowing function. The blow-blowing channel is opened in the die cavity to assist the blowing function in discharging waste outside the die. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figure 3 , Figure 4As shown, the bottom of the upper die base 18 is connected to one end of the upper pad 19, and the other end of the upper pad 19 is connected to the upper fixing plate 3. A pressure plate 4 is provided below the upper fixing plate 3. The bottom of the upper pad 19 is connected to one end of the punching punch 6, and the other end of the punching punch 6 passes through the upper fixing plate 3 and the pressure plate 4 respectively. A lower lifting plate 11 is provided above the lower die base 13. Several die fixing support blocks 10 are connected to the lower die base 13. The bottom of the die fixing support blocks 10 is connected to the lower die base 13, and the top of the die fixing support blocks 10 passes through the lower lifting plate 11 and is located above the lower lifting plate 11. The bottom of the die fixing seat 9 is connected to the lower lifting plate 11 located on one side of the die fixing support block 10. A punching die 7 is embedded in the top of the die fixing seat 9. The punching die 7 is provided with a punching opening 20. An air blowing channel 16 is provided inside the die fixing seat 9.
[0021] The position of the blanking opening 20 on the blanking die 7 corresponds to the end of the blanking punch 6. The bottom of the blanking opening 20 is connected to the blanking channel 8, and one side of the blanking channel 8 is connected to the air outlet of the air blowing channel 16.
[0022] The air blowing channel 16 has an L-shaped pipe structure. The air blowing outlet of the air blowing channel 16 is connected to one side of the material discharge channel 8, and the air blowing inlet of the air blowing channel 16 extends out of the lower part of the die fixing seat 9.
[0023] Air pipe channels are provided in the lower lifting plate 11 and the lower mold base 13 respectively. An air inlet pipe 17 is provided in the air pipe channel. The air inlet pipe 17 enters from the air pipe channel in the lower lifting plate 11 and the lower mold base 13 to the air inlet of the air blowing channel 16.
[0024] An air inlet connector 12 is fitted onto the head of the air inlet pipe 17.
[0025] A guide post 14 is provided on one side of the upper pad 19, the upper fixing plate 3, and the pressure plate 4. The top of the guide post 14 is connected to the upper mold base 18 by connecting bolts.
[0026] A guide sleeve 15 is provided on one side of the lower lifting plate 11. The lower part of the guide sleeve 15 is embedded in the lower mold base 13, and the guide sleeve 15 cooperates with the guide post 14.
[0027] At least two die fixing support blocks 10 are provided.
[0028] The upper die part of this utility model is consistent with the structure of a common punching die. The lower die part is a continuous die structure and requires floating feeding. The punching die 7, the die fixing seat 9 and the lower lifting plate 11 are fixed together, and a spring is placed below. Together with the guide post 14 and the guide sleeve 15, they form a movable punching die with the function of floating feeding.
[0029] After the blanking is completed, the scrap 1 is discharged through a dark scrap discharge chute (i.e., discharge channel 8) formed by the blanking die 7 and the die fixing seat 9. However, this alone may result in the scrap being stuck due to grease or scrap generated by the die and unable to be discharged. Therefore, it is necessary to further blow out the scrap through the external strong gas formed by the air blowing joint 12, the air blowing channel 16, and the air inlet pipe 17 to ensure safe production.
