Description

Technical Field

[0001] This application belongs to the technical field of progressive dies, and particularly relates to a stamping progressive die for a blade deflector bar assembly. Background Art

[0002] Blade deflector bar assemblies are widely used in power equipment, mainly for optimizing fluid flow and improving equipment performance. As Figure 1 shown in the blade deflector bar 1, which includes a blade 11 and a steel strip 12. During the production process, the inserts 111 at both ends of the blade 11 are inserted into the holes on both sides of the steel strip 12, and then the inserts 111 of the blade 11 are riveted to the steel strip 12. Then, the riveted blade 11 and the steel strip 12 are bent together by 15° to complete the production. Currently, in the industry, the production of blade deflector bar assemblies is completed through three manual operations: inserting the blade 11, riveting the blade 11 and the steel strip 12, and bending the blade 11 and the steel strip 12 together. Moreover, all three operations are manual, resulting in disadvantages such as low production efficiency, poor product size stability, and high production costs. Summary of the Utility Model

[0003] The purpose of this application is to provide a stamping progressive die for a blade deflector bar assembly. By integrating the traditional three manual operations (inserting, riveting, and bending) into one stamping progressive die, automated production is achieved, significantly improving production efficiency, reducing labor costs and production cycles. Additionally, automated production reduces errors caused by manual operations, making product sizes more accurate and stable, and improving the overall quality of the product.

[0004] The technical solution adopted by this application to solve the above technical problems is to propose a stamping progressive die for a blade deflector bar assembly, including: an upper die assembly and a lower die assembly. A guiding assembly is connected between the upper die assembly and the lower die assembly. A steel strip feeding assembly, a blade feeding assembly, a riveting assembly, and a bending assembly are also provided between the upper die assembly and the lower die assembly. The steel strip feeding assembly feeds the steel strip into the progressive die. The blade feeding assembly feeds the blade into the progressive die and inserts the inserts of the blade into the holes of the steel strip. The riveting assembly rivets the inserts of the blade to the steel strip. The bending assembly bends the riveted steel strip and the blade together.

[0005] Through the above technical features, the pre-prepared steel strip is automatically fed into the designated position of the stamping progressive die by the steel strip feeding assembly. Subsequently, the blade feeding assembly feeds the blades into the progressive die, and under precise control, the inserts at both ends of the blades are accurately inserted into the hole positions on both sides of the steel strip. After the insertion is completed, the riveting assembly immediately operates to firmly rivet the inserts of the blades to the steel strip. Finally, the bending assembly uniformly bends the combined blades and steel strip that have completed riveting, usually bending 15° according to the design requirements. After the bending is completed, the required blade deflector strip assembly is obtained. Therefore, by integrating the traditional three manual operation processes (insertion, riveting, and bending) into one stamping progressive die, the present application realizes automated production, significantly improves production efficiency, reduces labor costs and production cycles, and the automated production reduces the errors caused by manual operations, making the product dimensions more accurate and stable, and improving the overall quality of the product.

[0006] Preferably, the steel strip feeding assembly includes a feeder disposed outside the progressive die. A lifter block is provided at the upper end of the lower die assembly. The lifter block is used to support both sides of the steel strip along the length direction. An elastic member is provided between the lifter block and the lower die assembly. The feeder feeds the steel strip into the progressive die and slides along the lifter block.

[0007] Through the above technical features, the feeder disposed outside the progressive die continuously and stably feeds the steel strip into the progressive die. The feeder ensures that the steel strip enters the die at the correct position and speed according to the preset program and speed. When the steel strip is fed into the die, it slides along the lifter block, ensuring that the steel strip remains stable during the forward movement and will not shift or deform due to uneven force.

[0008] Preferably, guide plates are provided on both sides of the upper end of the lifter block, and both sides of the steel strip along the length direction are in contact with the guide plates.

[0009] Through the above technical features, the guide plates ensure that the steel strip will not sway back and forth during the movement, facilitating subsequent operations.

[0010] Preferably, the blade feeding assembly includes a vibrating bowl disposed on one side of the progressive die, a side push slider slidably connected to the lower template, and a cylinder connected to one side of the side push slider. A first card slot is provided on the side push slider. The vibrating bowl feeds the blades into the first card slot of the side push slider. A second card slot corresponding to the first card slot is provided on the lower die assembly. The second card slot corresponds to the hole positions on the steel strip. The cylinder is used to drive the side push slider to slide along the lower die assembly, thereby feeding the blades into the second card slot so that the inserts on the blades correspond to the hole positions on the steel strip.

[0011] Through the above technical features, the vibrating disk on one side of the progressive die is responsible for sorting and orienting the blades, and then feeding them into the first card slot of the side push slider one by one. When the cylinder receives the start signal, it drives the side push slider to slide along the preset track of the lower die assembly, so that the blades in the first card slot are pushed towards the second card slot. When the side push slider pushes the blade into the second card slot, the inserts on the blade will automatically align with the holes on the steel strip. This alignment process provides an accurate positioning basis for the subsequent riveting process. The lifting block lifts the steel strip above the lower die assembly, facilitating the side push slider to feed the blade under the steel strip.

[0012] Preferably, the blade feeding assembly further includes a pressure rod arranged on the upper die assembly. A first avoidance hole is correspondingly arranged on the lifting block for the pressure rod, and a plug hole is correspondingly arranged on the lower die assembly for the pressure rod. When the upper die assembly moves towards the side close to the lower die assembly, the pressure rod passes through the first avoidance hole and is inserted into the plug hole, driving the lifting block to move towards the side close to the lower die assembly, so that the inserts of the blades are inserted into the holes of the steel strip.

[0013] Through the above technical features, when the upper die assembly moves towards the side close to the lower die assembly, the pressure rod on the upper die assembly will move downward accordingly. The lifting block is provided with a first avoidance hole corresponding to the pressure rod, allowing the pressure rod to pass through unobstructed during the movement. As the upper die assembly continues to move downward, the pressure rod will pass through the first avoidance hole on the lifting block and be inserted into the plug hole on the lower die assembly, ensuring the accurate alignment between the upper die assembly and the lower die assembly. After the pressure rod is inserted into the plug hole, its downward thrust will act on the lifting block, causing the lifting block to move towards the side close to the lower die assembly. Since the lifting block originally supports both sides of the steel strip, its movement will drive the steel strip to move downward together. At the same time, since the blades have been fed to the position corresponding to the holes of the steel strip through the previous feeding process, the downward movement of the steel strip will cause the inserts of the blades to be automatically inserted into the holes of the steel strip, completing the insertion action.

[0014] Preferably, the riveting assembly includes a riveting rod connected to the upper die assembly. The riveting rod is located above the second card slot. A second avoidance hole is correspondingly arranged on the side push slider for the riveting rod. When the upper die assembly moves towards the side close to the lower die assembly, the riveting rod passes through the second avoidance hole to rivet the steel strip and the blade at the second card slot.

[0015] Through the above technical features, when the upper die assembly moves downward, the riveting rod passes through the second avoidance hole. As the upper die assembly continues to descend, the riveting rod will apply pressure to the steel strip and the blade located at the second card slot, firmly riveting the inserts of the blade to the steel strip.

[0016] Preferably, it further includes a shaping component. The shaping component includes a shaping rod connected to the upper die component. The shaping rod is arranged inside the riveting rod. A third avoidance hole corresponding to the shaping rod is provided on the side push slider. When the upper die component moves towards the lower die component, the shaping rod passes through the third avoidance hole to shape the riveted part of the steel strip and the blade, ensuring the flatness of the riveting.

[0017] Through the above technical features, when the upper die component moves downward, the shaping rod passes through the third avoidance hole, applying a certain pressure or thrust to the riveted part of the steel strip and the blade, adjusting the shape and position of the riveted part to ensure its flatness and tightness.

[0018] Preferably, the bending component includes a lower insertion pin and an upper insertion pin. The lower insertion pin is connected to the lower die component. The lower insertion pin is used to support the lower end of the blade flow guide strip after riveting. The upper insertion pin is correspondingly connected to the upper die component relative to the lower insertion pin. When the upper die component moves towards the lower die component, the upper insertion pin presses on the blade flow guide strip, thereby bending the blade flow guide strip.

[0019] Through the above technical features, when the upper die component of the stamping progressive die moves towards the lower die component, the upper insertion pin also descends accordingly. The upper insertion pin will gradually approach and finally press on the blade flow guide strip. Since the relative position between the upper insertion pin and the lower insertion pin is fixed, and the upper insertion pin applies a certain pressure to the blade flow guide strip during the descending process, the blade flow guide strip bends at the support point of the lower insertion pin. The lower insertion pin is connected to the lower die component and can support the lower end of the blade flow guide strip after riveting. When the blade flow guide strip is fed into the die for subsequent processing, the lower insertion pin can provide a stable support point. At the same time, the upper insertion pin is correspondingly connected to the upper die component relative to the lower insertion pin, ensuring that when the upper and lower die components are closed, the upper insertion pin can accurately align and act on the blade flow guide strip.

[0020] In summary, the present application has the following beneficial effects:

[0021] (1) By integrating the traditional three manual operation processes (insertion, riveting, bending) into a stamping progressive die, the present application realizes automated production, significantly improves production efficiency, reduces labor costs and production cycles, and the automated production reduces errors caused by manual operations, making the product dimensions more accurate and stable, and improving the overall quality of the product;

[0022] (2) Through the ingenious cooperation of the pressure rod, the first avoidance hole and the insertion hole, the present application realizes the automatic alignment and insertion of the blade insert and the steel strip hole position without manual intervention, greatly improving the insertion efficiency and accuracy;

[0023] (3) By combining the riveting action with the movement of the upper and lower dies of the stamping progressive die, the present application realizes the automation of riveting, greatly improves the production efficiency, and reduces the time and cost of manual operation.

Specific Embodiments

[0030] The following are specific embodiments of the present application in combination with the drawings, and the technical solutions of the present application will be further described, but the present application is not limited to these embodiments.

[0031] As Figure 2 , Figure 3 shown, the present application discloses a stamping progressive die for a blade guide strip assembly, including: an upper die assembly 2 and a lower die assembly 3.

A guiding assembly is connected between the upper die assembly 2 and the lower die assembly 3, and the upper die assembly 2 can move back and forth along the guiding assembly in a direction close to or away from the lower die assembly 3.

[0032] In this application, a steel strip feeding component 4, a blade feeding component 5, a riveting component 6, a shaping component 8 and a bending component 7 are provided between the upper die component 2 and the lower die component 3. The steel strip feeding component 4 feeds the steel strip 12 into the progressive die. The blade feeding component 5 feeds the blade 11 into the progressive die and inserts the insert piece 111 of the blade 11 into the hole position of the steel strip 12. The riveting component 6 rivets the insert piece 111 of the blade 11 onto the steel strip 12. The shaping component 8 shapes the riveting part of the steel strip 12 and the blade 11 to ensure the flatness of the riveting. The bending component 7 bends the riveted steel strip 12 and blade 11 together.

[0033] The steel strip feeding component 4 includes a feeder 41 arranged outside the progressive die and a lifter block 42 arranged at the upper end of the lower template 32. The lifter block 42 is used to support both sides of the steel strip along the length direction. Guide plates are arranged on both sides of the lifter block 42, and an elastic member is arranged between the lifter block 42 and the lower template 32. The feeder 41 continuously and stably feeds the steel strip 12 into the progressive die. When the steel strip 12 is fed into the die, the steel strip 12 will slide along the lifter block 42, ensuring that the steel strip 12 remains stable during the forward movement and will not shift or deform due to uneven stress. The guide plates on both sides of the lifter block 42 ensure that the steel strip 12 will not sway back and forth during the movement.

[0034] As Figure 2 、 Figure 4 shown, the blade feeding component 5 includes a vibrating bowl 51 arranged on one side of the progressive die, a side push slider 52 slidably connected to the lower template 32, and a cylinder 53 connected to one side of the side push slider 52. A first card slot 521 is arranged on the side push slider 52. The vibrating bowl 51 feeds the blade 11 into the first card slot 521 of the side push slider 52. The side push slider 52 fixes the blade 11 in the first card slot 521 by negative pressure adsorption.

[0035] A second card slot 31 corresponding to the first card slot 521 is arranged on the lower template 32. The second card slot 31 corresponds to the hole position on the steel strip 12. The cylinder 53 drives the side push slider 52 to slide along the lower die component 3, so as to feed the blade 11 into the second card slot 31, making the insert piece 111 on the blade 11 correspond to the hole position on the steel strip 12.

[0036] The blade feeding component 5 further includes a pressure rod 54 arranged on the upper die component 2. A first avoidance hole is arranged on the lifter block 42 corresponding to the pressure rod 54, and a plug hole is arranged on the lower die component 3 corresponding to the pressure rod 54. When the upper die component 2 moves towards the lower die component 3, the pressure rod 54 passes through the first avoidance hole and is inserted into the plug hole, and drives the lifter block 42 to move towards the lower die component 3, so that the insert piece 111 of the blade 11 is inserted into the hole position of the steel strip 12.

[0037] As Figure 5As shown, the riveting assembly 6 includes a riveting rod connected to the upper die assembly 2. The riveting rod is located above the second card slot 31. A second avoidance hole is provided on the side push slider 52 corresponding to the riveting rod. When the upper die assembly 2 moves towards the lower die assembly 3, the riveting rod passes through the second avoidance hole to rivet the steel strip and the blade at the second card slot 31, firmly riveting the insertion piece of the blade to the steel strip.

[0038] The shaping assembly 8 includes a shaping rod connected to the upper die assembly 2. The shaping rod is arranged inside the pressing rod 54. A third avoidance hole is provided on the side push slider 52 corresponding to the shaping rod. When the upper die assembly 2 moves towards the lower die assembly 3, the shaping rod passes through the third avoidance hole to apply a certain pressure or thrust to the riveted part of the steel strip and the blade, adjusting the shape and position of the riveted part to ensure its flatness and tightness.

[0039] The bending assembly 7 includes a lower inserting pin 72 and an upper inserting pin 71. The lower inserting pin 72 is connected to the lower die assembly 3. The lower inserting pin 72 is used to support the lower end of the blade flow guide strip after riveting. The lower inserting pin 72 provides a stable support point for the blade flow guide strip. The upper inserting pin 71 is connected to the upper die assembly 2 corresponding to the lower inserting pin 72. When the upper die assembly 2 moves towards the lower die assembly 3, the upper inserting pin 71 presses on the blade flow guide strip, applying a certain pressure to the blade flow guide strip, causing the blade flow guide strip to bend at the support point of the lower inserting pin 72.

[0040] Working principle: Through the steel strip feeding assembly 4, the pre-prepared steel strip 12 is automatically fed into the designated position of the stamping progressive die. Subsequently, the blade feeding assembly 5 feeds the blade 11 into the progressive die, and under precise control, inserts the insertion pieces 111 at both ends of the blade 11 accurately into the hole positions on both sides of the steel strip 12. After the insertion is completed, the riveting assembly 6 immediately works to firmly rivet the insertion piece 111 of the blade 11 to the steel strip 12. Finally, the bending assembly 7 uniformly bends the combined blade 11 and steel strip 12 that have been riveted, usually bending 15° according to the design requirements. After the bending is completed, the required blade flow guide strip assembly is obtained.

[0041] Therefore, in this application, by integrating the traditional three manual operation processes (insertion, riveting, bending) into a single stamping progressive die, automated production is achieved, significantly improving production efficiency, reducing labor costs and production cycles. Moreover, automated production reduces errors caused by manual operation, making the product dimensions more accurate and stable, and improving the overall quality of the product.
