Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production and processing, in particular to a new type of blanking die without deformation. Background Technique

[0002] A blanking die is a tool or device used to shear or cut flat materials (such as metal plates, plastic plates, etc.) into the required shapes and sizes during the manufacturing process. They are usually made of strong materials such as steel to ensure that they can withstand high pressure and high shear forces, thus effectively cutting or stamping the materials.

[0003] A blanking die without deformation generally refers to a die with high design and manufacturing precision, stable operation, and capable of maintaining the shape and size of the material without deformation during use. During the blanking process, especially for the manufacturing of some parts that require high precision, such as automotive parts, electronic product casings, etc., using a blanking die without deformation is crucial because it can ensure that the produced parts have consistent dimensions and shapes, avoiding product quality problems caused by die deformation.

[0004] However, in the process of using most blanking dies, due to the springback of the product after directly punching the product, the product is uneven, resulting in the springback of the product during use, making the product unable to meet the flatness requirements of the customer's drawing. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a new type of blanking die without deformation, aiming to improve the problem that the product rebounds during use, making the product unable to meet the flatness requirements of the customer's drawing.

[0006] To achieve the above object, the utility model provides the following technical solution:

[0007] A new type of blanking die without deformation, including an upper die base, the upper surface of the upper die base is fixedly connected with an outer guide sleeve, the inner wall of the outer guide sleeve is slidably connected with an outer guide post, the outer wall of the outer guide sleeve is fixedly connected with a stop plate, the inner wall of the stop plate is fixedly connected with an inner guide post, the outer wall of the inner guide post is slidably connected with a lower template, the inner wall of the lower template is provided with an inner limit, the outer wall of the inner guide post is slidably connected with the inner wall of the inner limit, the inner wall of the stop plate is provided with a trimming punch, the inner wall of the stop plate is provided with a stripper plate, the outer wall of the trimming punch is provided with a trimming edge and a lower die edge, the lower surface of the lower template is fixedly connected with a lower backing plate, the upper surface of the lower template is provided with a lifter block, and the lower surface of the lower backing plate is provided with a support assembly for supporting the die.

[0010] Preferably, the upper surface of the lower die base is fixedly connected with an outer limit post, and the outer wall of the outer limit post is slidably connected to the inner wall of the upper die base.

[0011] Preferably, the lower surface of the stop plate is fixedly connected with an upper clamping plate, and the lower surface of the upper clamping plate is fixedly connected with an upper backing plate.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, the upper table of the punching press moves downward from top to bottom, driving the upper die base to move downward. The outer guide sleeve and the outer guide pillar accurately guide and correct the upper and lower dies to start closing. When the upper die descends to a certain position, the stripper plate presses the strip downward to move, and the trimming punch starts to work. When the upper die base continues to move downward and the trimming punch is made into an arc shape, the product will not be deformed, achieving the reduction of the manufacturing cost and processing time of the die, effectively suppressing the deformation of the product, and better meeting the quality requirements of the product required by the customer.

At the same time, the lifter block on the lower template lifts the strip, and the trimming punch disengages from the product, and the punching of the product is completed. When the trimming punch is made into an arc shape, the product will not be deformed and can be produced quickly, stably and efficiently, effectively improving the springback of the product and enabling the product to meet the flatness requirements of the customer's drawing.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the specification drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a new type of blanking die without deformation, including an upper die holder 1, an outer guide bushing 2 is fixedly connected to the upper surface of the upper die holder 1, an outer guide pillar 3 is slidably connected to the inner wall of the outer guide bushing 2, a stop plate 19 is fixedly connected to the outer wall of the outer guide bushing 2, an inner guide pillar 4 is fixedly connected to the inner wall of the stop plate 19, a lower template 15 is slidably connected to the outer wall of the inner guide pillar 4, an inner limit 5 is provided in the inner wall of the lower template 15, and the outer wall of the inner guide pillar 4 is slidably connected to the inner wall of the inner limit 5. A trimming punch 7 is provided on the inner wall of the stop plate 19, a stripper plate 8 is provided on the inner wall of the stop plate 19, a trimming edge 9 and a lower die edge 10 are provided on the outer wall of the trimming punch 7, a lower backing plate 14 is fixedly connected to the lower surface of the lower template 15, a lift block 17 is provided on the upper surface of the lower template 15, a support assembly is provided on the lower surface of the lower backing plate 14, and the support assembly is used to support the die; the support assembly includes a lower die holder 11, the upper surface of the lower die holder 11 is fixedly connected to the lower surface of the lower backing plate 14, a lower pad foot 12 is fixedly connected to the lower surface of the lower backing plate 14, and a support plate 13 is fixedly connected to the lower surface of the lower pad foot 12;

[0025] Specifically, the upper die base 1 drives the outer guide sleeve 2 to slide on the outer wall of the outer guide pillar 3 to achieve the effect of the first limit. The stop plate 19 drives the inner guide pillar 4 to slide on the inner wall of the inner limit 5 to achieve the effect of the second limit. After the product is shaped and cut by the trimming punch 7 at the trimming edge 9 and the lower die edge 10, the upper and lower dies are accurately aligned by the outer guide pillar 3 and start to close. When the upper die descends to a certain position, the stripper plate 8 presses the strip and moves downward. The upper clamping plate 21 and the upper backing plate 20 are used to maintain the stability and fixity of the replacement when the stop plate 19 drives the trimming punch 7 and the stripper plate 8 to insert into the inner wall of the lower die edge 10. The trimming punch 7 starts to work. When the upper die continues to move downward and the punch is made into an arc shape, the product will not be deformed.

[0026] Refer to Figures 2 - 3 , the lower surface of the outer guide pillar 3 is fixedly connected to the upper surface of the lower die base 11, and the right outer wall of the lower template 15 is fixedly connected with a sensor assembly 18; the upper surface of the lower die base 11 is fixedly connected with an outer limit post 16, and the outer wall of the outer limit post 16 is slidably connected to the inner wall of the upper die base 1; the lower surface of the stop plate 19 is fixedly connected with an upper clamping plate 21, and the lower surface of the upper clamping plate 21 is fixedly connected with an upper backing plate 20;

[0027] Specifically, the sensor assembly 18 can be used to sense whether the upper and lower dies are tightly closed. During use, the stop plate 19, the upper backing plate 20 and the upper clamping plate 21 play a role in increasing the stability and fixity of the trimming punch 7, the insertion pin 6 and the inner guide pillar 4 during use.

[0028] Refer to Figure 2 , the lower surface of the upper backing plate 20 is fixedly connected to the upper surface of the upper die base 1; the inner wall of the stop plate 19 is provided with an insertion pin 6, and the outer walls of the trimming punch 7 and the stripper plate 8 are fixedly connected to the inner walls of the upper clamping plate 21 and the upper backing plate 20; the outer wall of the inner guide pillar 4 is fixedly connected to the inner walls of the upper backing plate 20 and the upper clamping plate 21;

[0029] Specifically, the upper clamping plate 21 and the upper backing plate 20 play a role in further fixing the trimming punch 7 and the stripper plate 8, increasing the effect of shaping and cutting the product by the trimming punch 7 at the trimming edge 9 and the lower die edge 10, and avoiding the failure of product cutting and shaping due to instability.

[0030] Working principle: When the device needs to be used, the upper table of the punching press moves downward from top to bottom, driving the upper die holder 1 and the outer guide sleeve 2 of the die to move downward. At this time, the outer guide sleeve 2 is driven by the upper die holder 1 to slide on the outer wall of the outer guide pillar 3 to achieve the effect of the first limit, and the inner guide pillar 4 is driven by the stop plate 19 to slide on the inner wall of the inner limit 5 to achieve the effect of the second limit. During use, after the trimming punch 7 shapes and cuts the product at the trimming edge 9 and the lower die edge 10, the upper and lower dies are accurately aligned by the outer guide pillar 3 and start to close. When the upper die descends to a certain position, the stripper plate 8 presses the strip downward, and the upper clamping plate 21 and the upper backing plate 20 are used to maintain the stability and fixity of replacement when the stop plate 19 drives the trimming punch 7 and the stripper plate 8 to insert into the inner wall of the lower die edge 10. The trimming punch 7 starts to work, and the upper die continues to move downward. After the punch is made into an arc shape, the product will not deform. Since there will be springback and the product will be uneven after directly punching the product, according to the previous solution, sizing was required. Now, the punch for punching the product has been optimized, and the contact surface of the punch is changed to an arc shape, which can effectively improve the springback of the product and make the product meet the flatness requirements of the customer's drawing, reducing the manufacturing cost and processing time of the die. During use, the lower die holder 11 is better supported by the support plate 13 and the lower pad feet 12 during the stamping process, and the effect of preventing the product from deforming during stamping is achieved during use. After the upper table of the punching press reaches the bottom dead center position, it starts to rise, driving the upper die part to move upward. At the same time, the lifter block 17 on the lower template 15 lifts the strip, and the trimming punch 7 disengages from the product, completing the punching of the product. After the punch is made into an arc shape, the product will not deform. The sensor assembly 18 outside the lower backing plate 14 and the lower template 15 plays an inductive role during use, ensuring that the previous step is completed before the next step can be entered during the use of the die, and avoiding accidents.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
