Detailed implementation manners

[0036] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0037] As Figure 2-11 shown, a die for processing throttle valve sheets includes, from top to bottom, an upper die assembly, a blanking assembly, and a lower die assembly in sequence. The upper die assembly and the lower die assembly slide vertically through guide columns and guide sleeves. The guide columns and guide sleeves are prior arts and will not be elaborated here.

[0038] The upper die assembly includes, fixedly arranged from top to bottom in sequence, an upper supporting plate 90, an upper die base 91, an upper backing plate 92, and an upper clamping plate 93.

[0039] The unloading assembly includes a stop plate 94, a stripping plate 95, and a unloading spring assembly that are fixedly arranged from top to bottom in sequence. The upper support plate 90 elastically supports the stripping plate 95 through the unloading spring assembly. There is a gap between the stop plate 94 and the upper clamping plate 93.

[0040] The lower die assembly includes a concave template 96, a lower backing plate 97, and a lower die base 98 that are fixedly arranged from top to bottom in sequence.

[0041] The mold further includes a punching component unit, a bulging component unit, a bending component unit, a blanking component unit, and a blowing component unit that are arranged in sequence along the feeding sequence direction. The feeding direction is set along the length direction of the strip, which is also the front-back direction, and the width direction of the strip is set as the left-right direction.

[0042] The punching component unit roughly cuts out a product of the first process with three claws on the strip 8. The middle area of the left side or the right side of the product of the first process is connected to the strip 8. When punching, the product of the first process has three claws, which is for turning up the three claws upwards subsequently. The three claws are connected by the left side, the right side, and the bottom side AB. The bottom side is perpendicular to the feeding direction.

[0043] The bulging component unit bulges the strip 8 in the second process. According to the shape requirements of the final product, it is necessary to bulge near the bottom side AB to press out a rib bulge perpendicular to the bottom side AB.

[0044] The bending component unit bends the end of each claw of the product upwards by 90° to form a product of the third process.

[0045] The blanking component unit is used to separate the middle areas of the left side and the right side from the strip 8; the blowing component unit is used to blow the separated product into the material box.

[0046] The punching die of the punching component unit, the bulging die of the bulging component unit, the bending die 572 of the bending component unit, and the blanking die 32 of the blanking component unit are respectively fixed to the concave template 96;

[0047] The punching punch of the punching component unit, the bulging punch 21 of the bulging component unit, and the blanking punch 31 of the blanking component unit are respectively fixed to the upper clamping plate 93;

[0048] The bending punch 55 of the bending component unit is fixed to the stripping plate 95. In this way, different units are integrated onto the mold.

[0049] The strip 8 is elastically supported above the cavity plate 96 by the elastic guide pin 42 before the mold is closed. After the stripper plate 95 presses down to contact the strip and then continues to move down until the strip falls onto the cavity plate. The outer surface of the elastic guide pin is provided with a groove, and the width edge of the strip can extend into the groove, so that the elastic guide pin supports the strip 8. The elastic guide pin has its own elasticity. After the stripper plate 95 presses down the elastic guide pin, the elastic guide pin is compressed into the cavity plate 96. After the stripper plate 95 moves up, the elastic guide pin automatically exposes above the cavity plate 96.

[0050] Among them, the preferred embodiment of the unloading spring assembly is: including a plug 61 arranged in the upper bolster 90 and a spring 62 arranged in the through hole of the upper die base 91; the unloading spring assembly further includes a coaxial upper bolt 63, a gasket 64 sleeved outside the upper bolt 63, an axially through equal-height cylinder 65 and a lower bolt 66.

[0051] The top surface of the upper backing plate 92 is provided with a groove for accommodating the gasket 64, and the gasket 64 is placed below the nut of the upper bolt 63; the outer diameter of the gasket 64 is larger than the nut of the upper bolt 63.

[0052] Both ends of the spring 62 abut against the gasket 64 and the plug 61, and the bottom end of the spring 62 is sleeved outside the nut of the upper bolt 63.

[0053] The upper bolt 63 and the lower bolt 66 respectively extend into both ends of the equal-height cylinder 65, and the upper bolt 63 and the lower bolt 66 are respectively threadedly connected to the inner wall surface of the equal-height cylinder 65; the equal-height cylinder 65 is axially through.

[0054] Both ends of the equal-height cylinder 65 abut between the bottom surface of the gasket 64 and the top surface of the stripper plate 95, and the equal-height cylinder 65 has no displacement relative to the stripper plate 95. The equal-height cylinder 65 is respectively freely sleeved inside the upper backing plate 92, the upper clamping plate 93 and the stop plate 94.

[0055] The lower bolt 66 is arranged in the stripper plate 95, and a stepped hole is provided on the bottom surface of the stripper plate 95 to limit the upward movement of the nut of the lower bolt 66. The number of the unloading spring assemblies is multiple, preferably 6.

[0056] Initially, under the action of gravity, the upper bolt 63 presses the gasket 64, the stop plate 94 presses the nut of the lower bolt 66, and the stop plate 94 and the stripper plate 95 are hoisted between the lower bolt 66 and the equal-height cylinder 65. When the upper die base 91 moves down, the upper clamping plate 93 moves down to fit the stop plate 94, and the gap between them becomes smaller and smaller, and the spring 62 is compressed. The upper die base 91 and the upper backing plate 92 move down relative to the equal-height cylinder 65, and the gasket 64 moves up relative to the upper die base 91 to compress the spring 62, so as to elastically press the strip 8 by the stripper plate 95.

[0057] The punching component unit can directly punch out Figure 6 、 Figure 7The product of the first process shown has a shape of the punching punch and the punching die that matches the shape of the product of the first process. However, this easily causes the product of the first process to warp. Therefore, the following step-by-step stamping technical solution is adopted.

[0058] A preferred embodiment of the punching component unit is as follows: The punching punch includes a first punch 11, a second punch 12, and a third punch 13 arranged at intervals along the feeding direction. The punching die of the punching component unit includes a first die 14, a second die 15, and a third die 16;

[0059] In the direction perpendicular to the feeding direction, the first punch 11 and the second punch 12 are arranged at intervals.

[0060] The strip 8 is processed by the first punch 11 and the first die 14 to form a first hole 17. The two first holes 17 in the feeding direction are arranged at intervals to form an intermediate area on the left side. Adjacent first holes 17 are punched on the strip 8 to process the left edge of the product.

[0061] The strip 8 is processed by the second punch 12 and the second die 15 to form a second hole 18. The two second holes 18 in the feeding direction are arranged at intervals to form an intermediate area on the right side. Adjacent second holes 18 are punched on the strip 8 to process the right edge of the product.

[0062] The adjacent side edges of the first hole and the second hole are the right edge AFE and the left edge BCD of the product respectively.

[0063] The strip 8 is processed by the third punch 13 and the third die 16 to form a third hole. The third hole connects the second hole 18 and the first hole 17 and processes the front edge and the rear edge of the adjacent products to separate two adjacent products in the feeding direction. The rear edges of the first hole and the second hole are cut out in the feeding direction, and the front edges of the adjacent first hole and the second hole are cut out.

[0064] It is easy to think that a punching waste channel for the waste generated by the punching component unit to fall is provided on the lower die assembly. When the upper die assembly moves down, the stripper plate elastically presses the strip 8 until the strip 8 lands on the concave template 96. Through holes are provided on the stop plate 94 and the stripper plate 95 for the first punch 11, the second punch 12, and the third punch 13 to move down relative to the stripper plate and act on the corresponding first die 14, second die 15, and third die 16. The mold feeds the strip into the punching component unit, the embossing component unit, the bending component unit, and the blanking component unit according to the specified pitch and direction through a feeder.

[0065] The punching component unit is also provided with a positioning punch 19 and a positioning die 20. The positioning punch is fixed on the upper clamping plate 93 and freely passes through the stop plate and the stripper plate; the positioning die 20 is fixed on the concave template. The positioning punch 19 and the positioning die 20 are pre-processing procedures for the strip, in order to process positioning holes near the edge of the strip 8 before the first process. A plurality of guide posts are fixed on the stripper plate, and guide holes corresponding to the guide posts are provided on the concave template, so that during the feeding process of the strip, the guide posts can extend downward into the positioning holes to position the strip 8 on the concave template.

[0066] Among them, the caulking die of the caulking component unit includes a caulking protrusion 22 provided on the concave template 96 and a caulking punch 21 fixedly connected to the upper clamping plate 93; the caulking punch 21 is respectively slidably connected to the stop plate 94 and the stripper plate 95.

[0067] The shape of the caulking protrusion 22 matches the profile of the throttle valve sheet; it protrudes upward. The caulking protrusion 22 is provided on the caulking die, and the caulking die is embedded in the concave template.

[0068] The caulking punch 21 is provided with a caulking groove 211 for accommodating the caulking protrusion 22 at a corresponding position of the caulking protrusion 22;

[0069] When the upper die base 91 moves downward, the strip 8 is clamped between the caulking punch 21 and the caulking protrusion 22. The stripper plate elastically presses the strip onto the concave template 96, and the caulking protrusion 22 ejects a ribbed package on the product in the first process, and the caulking punch 21 presses the product around the ribbed package.

[0070] Among them, the bending component unit includes a fixing plate 53 fixed inside the stripper plate 95, an upper pressure pin 54 elastically supported inside the fixing plate 53, and a bending punch 55 fixed on the fixing plate 53.

[0071] The fixing plate 53 is provided with three vertically penetrating through holes in the circumferential direction of the bending punch 55 for accommodating the unbent product; that is, when the bending punch 55 presses down on the top surface of the middle area of the product, the top surfaces of the three claws evenly distributed in the circumferential direction of the middle area are not pressed. The bottom surface of the fixing plate 53 is located on the same horizontal line as the bottom surface of the bending punch 55.

[0072] The bending component unit also includes a bending inner die 571 that elastically moves up and down relative to the concave template 96 and three bending dies 572 fixedly connected to the concave template 96. The bending inner die 571 floatingly supports the bottom surface of the middle area of the product being bent.

[0073] The bending inner female die 571 is used to abut against the bottom surface of the bent product. The bending inner female die 571 freely passes through the concave template 96. The lower backing plate 97 and the lower die base 98 are provided with corresponding spring channels. An elastic member is arranged in the spring channel. The elastic member is located in the lower die base 98 and elastically supports the bottom surface of the bending inner female die 571. Since the bottom surface of the fixing plate 53 and the bottom surface of the bending male die 55 are on the same horizontal line, when the dies are closed, the bending male die 55 presses the bending inner female die 571 to move downward, and the product is placed between the bending male die 55 and the bending inner female die 571.

[0074] Three bending female dies 572 surround the cylindrical bending inner female die 571. The side of the bending female die 572 close to the bending inner female die 571 has an arc-shaped surface, and the side of the bending female die 572 far from the bending inner female die 571 is a plane. When the dies are opened, the outer edges of the three claws of the product are placed on the plane of the bending female die 572. When the dies are closed, the bending inner female die 571 moves downward relative to the bending female die 572, and the arc-shaped surface of the bending female die 572 and the edge of the bending male die 55 cooperate to turn up the three claws of the product.

[0075] The bending component unit further includes a floating block 56 that supports the bottom surface of the floating strip 8. The top ends of the bending inner female die 571 and the three bending female dies 572 pass through the floating block 56 but do not pass through the floating block 56. Through holes are provided inside the floating block 56 to accommodate the top ends of the bending inner female die 571 and the three bending female dies 572.

[0076] When the initial upper clamping plate 93 has not moved downward, the top surfaces of the three bending female dies 572, the bending inner female die 571, and the floating block 56 are flush and protrude from the concave template 96, and together with the elastic guide pins, support the strip.

[0077] Preferably, a plurality of ejector pins 58 are provided on the bottom surface of the floating block 56. The bottom surface of the ejector pin 58 is supported by a spring arranged inside the lower backing plate 97 and the lower die base 98. A vertical through hole is vertically provided in the concave template 96. The upper part of the vertical through hole accommodates the floating block 56, and the lower part of the vertical through hole is fixedly connected to the lower fixing block 59. The ejector pin 58 freely passes through the lower fixing block 59, and the two are slidably connected. The lower fixing block 59 and the floating block 56 are arranged at intervals. The lower fixing block 59 serves to limit the downward floating distance of the floating block 56. When the floating block 56 moves down to the lower fixing block 59, the strip 8 falls onto the concave template 96. A lower spring 52 and a lower plug are provided on the bottom surface of the ejector pin 58, and the lower plug is screwed onto the lower die base 98.

[0078] The bending female die 572 is arranged on the circumferential outer part of the bending inner female die 571;

[0079] When the mold is closed, after the fixed plate 53 and the floating block 56 press and clamp the strip 8, the floating block 56 moves downward until the strip 8 falls onto the concave template 96. The bending punch 55 presses the inner bending die 571 to move downward, and the bending die 572 and the inner bending die 571 fold up each claw. When the mold is opened, each folded claw is likely to hold on the bending punch, causing the product to be torn from the strip. Therefore, the upper pressure pin 54 is needed to push the product downward.

[0080] The upper pressure pin 54 is a prior art, and the following technical solution can be referred to: The upper pressure pin 54 can slide relative to the stripper plate. A spring is fixed on the top surface of the upper pressure pin, and the spring is installed in the stop block 94. Initially, the bottom surface of the upper pressure pin protrudes from the stripper plate. When the mold is closed, the bottom surface of the upper pressure pin is pressed back into the stripper plate. When the mold is opened, the upper pressure pin automatically pops out under the action of the spring and returns to the initial position.

[0081] Among them, the blanking component unit includes a blanking punch 31 fixed on the upper clamping plate 93 and a blanking die 32 fixed inside the concave template 96.

[0082] The blanking punch 31 is slidably connected to the stop block 94 and the stripper plate 95 respectively.

[0083] The cross-section of the blanking punch 31 is generally V-shaped, surrounding the product, and cutting off the connections between the left and right sides of the product and the strip 8. The inner edge of the blanking punch 31 is consistent with the shapes of the left and right sides of the product. The waste material falls out from the lower die assembly.

[0084] Among them, the air blowing component unit includes an air blowing pin 41 for providing air flow, an aggregate groove 961 opened on the concave template 96, and an elastic component arranged inside the concave template 96 for resetting the air blowing pin after being pressed. The air blowing pin 41 blows the product towards the aggregate groove 961. The air blowing pin 41 is a prior art, and reference can be made to the Chinese utility model patent "A Precision Parts Processing Die for Facilitating Material Discharge" with the application number CN202122372018.2. Preferably, the air blowing pin 41 is placed on one side of the blanking groove close to the pressing bulge 22.

[0085] This mold realizes the automated production of micro-miniature automotive products and three-claw throttle valve plates, improves the possibility of mass production of products, ensures the consistency of product quality, increases the qualified rate of products, and reduces the human and material resources in production. This type of product can be mass-produced through this structural mold.

[0086] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
