DETAILED DESCRIPTION

[0044] See also Figures 1 - 21 In this embodiment, a multi-mold matching punching and forming mold set includes mold one, mold two and mold three; Figure 14 As shown, the product to be punched;

[0045] like Figures 1 - 6 As shown, the mold 1 includes a polarity cutting station 1, a gluing station 2, a U-shaped forming station 3, a cutting and separating station 4 and a track 14 for product conveying, the discharge end of the track 14 is provided with a product floating track 11 corresponding to the cutting and separating station 4 and a pressing and floating assembly installed at the upper mold of the mold 1, and the mold 1 also includes an upper mold plate A21 and a lower mold plate A28;

[0046] The upper template A21 is located at the upper die of the first die, and the lower template A28 is located at the lower die of the first die;

[0047] The polarity cutting station 1 includes a rib cutting and blanking block 5, a polarity rib cutting lower knife 6, and an upper knife seat 20. An upper polarity cutting knife 17 corresponding to the polarity rib cutting lower knife 6 is installed on the upper knife seat 20. A glue application and rib cutting unloading insert 18 and a unloading plate A19 are provided on one side of the upper polarity cutting knife 17.

[0048] The glue application station 2 includes a glue application upper knife 22 installed on the upper template A21, a glue application insert 7 and a glue application support block 8 installed on the lower template A28. A lower knife seat 27 is installed on the lower template A28; The U-shaped forming station 3 includes a U-shaped forming lower knife 9 installed on the lower template A28 and a U-shaped forming upper knife assembly 23 installed on the upper template A21. The bottom of the U-shaped forming upper knife assembly 23 is connected to an upper knife roller 231, and one side of the U-shaped forming upper knife assembly 23 is connected to a forming pressing block 232; The cutting and separating station 4 includes a rib cutting upper knife 24 installed on the upper template A21, a rib cutting lower knife assembly 10 installed on the lower template A28, a forming unloading insert A25, and a rib cutting unloading insert 26;

[0049] Since the product only needs to complete U-shaped forming at one end, the U-shaped forming lower knife 9 adopts an integral structure, and the component is small and convenient for installation.

[0050] Guide blocks 15 are provided on both sides of the feeding end of the track 14, and a pressing component 16 is provided on the top of the feeding end of the track 14; A side rib demolding guide block 13 is provided at the discharging end of the track 14, and track cover plates A12 are provided on both sides of the track 14; The guide block 15 mainly plays a guiding role for the material to be cut to enter the first die from the feeding mechanism of the equipment, and reduces the inertial force of the incoming material sheet to be cut through the action of the pressing wheel and spring in the pressing component 16, playing a role in blocking the material and ensuring accurate feeding;

[0051] The track 14 is an integral track, which floats up and down with the product during operation to complete the actions of each station, and makes clearance at the corresponding stations. The track cover plate A12 is also used to protect the side ribs to prevent the frame from jumping, which not only ensures the smooth forming of the product, but also enables the product to be smoothly transferred between each station;

[0052] The blank holding floating component includes a blank holding floating block 29 and a cylinder 32. The piston rod at the power output end of the cylinder 32 is connected to a thimble pressing block 31. The bottom of the thimble pressing block 31 is connected to a thimble. The blank holding floating block 29 is slidably installed on the thimble. A spring is sleeved on the thimble. Four groups of blank holding floating limit rods 30 are also installed on the blank holding floating block 29. The function of the blank holding floating component is to move downward with the upper die during the process of cutting the tie bars and separating. The downward movement distance of the component is restricted by the blank holding floating limit rods 30, and the product is restricted by the blank holding floating block 29. When the upper die moves upward, to ensure the smooth ejection of the product, the cylinder 32 is used to push the thimble pressing block 31 to make the blank holding floating block 29 continue to restrict the product until the product is ejected from the die. After the cylinder contracts, the component returns to its original state under the action of the spring.

[0053] After the material to be cut is fed in place and positioned by the die locating pins, each unloading insert and the upper knife move downward with the upper die part. After restricting the positions of the product and the outer frame, the unloading part stops moving downward, and each upper knife continues to move downward and cooperate with the corresponding lower knife to complete the work of the corresponding station, and then the die is lifted to unload the material. Among them, the polarity cutting station 1, the glue injection station 2, and the U-shaped forming station 3 work simultaneously. After that, the product reaches the cutting and separating station 4 under the action of the equipment dialing mechanism to complete the work of cutting the tie bars.

[0054] The U-shaped forming upper knife assembly 23 adopts the form of a combination of upper knife rollers 231 to reduce the damage to the product coating during the forming process. At the same time, a forming pressing block 232 is added to restrict the product during the forming process, prevent the product from warping and deforming during the forming process, and ensure the forming effect of the product.

[0055] After the material frame passes through the cutting and separating station 4 and the product is separated from the frame, the remaining side tie bars continue to be conveyed backward under the action of the equipment dialing component, and are guided by the side tie bar die exit guide block 13 to prevent the side tie bars from moving around until the side tie bars are pulled out of the track.

[0056] The product floating track 11 always floats with the product during the process of cutting the tie bars to support the product. After the cutting of the tie bars is completed, the product floating track 11 slightly lifts the product under the action of the bottom spring, so that the metal part is separated from the cutting lower knife assembly 10 of the tie bars, ensuring the smooth ejection of the product from the die and preventing the product coating from being scratched by the lower knife.

[0057] As Figure 16 and 17 shown, it is the product after passing through Die 1.

[0058] As Figures 7 - 11 shown, the Die 2 includes a pre-forming station 34, a forming station 33, a lower template B43, an upper template B45, and a linear floating mechanism. The pre-forming station 34 includes a pre-forming lower knife assembly 35 and a pre-forming floating block 36. The forming station 33 includes a forming lower knife assembly 37 and a forming floating block 38. The function of Die 2 is to further complete the two-wing bending process for the semi-finished product coming out of Die 1.

[0059] The upper template B45 is installed on the upper mold of mold 2, and the lower template B45 is installed on the lower mold of mold 2;

[0060] The preforming station 34 also includes a preforming upper knife B39, a molding unloading insert B40, and a floating rail B41. The lower knife fixing seat B42 is installed on the lower template B43, and the upper knife fixing seat B44 is installed on the upper template B45; the molding station 33 also includes a molding upper knife B47, and the molding station 33 is provided with a floating rail cover plate B48 and a unloading plate B49.

[0061] The linear floating mechanism includes a bending floating connection block B46 and a forming floating block insert B50, wherein the bending floating connection block B46 is connected to the forming floating block insert B50 via a plurality of connecting springs B511, the top of the bending floating connection block B46 is connected to a bending floating material guide rod B52, and a linear bushing B51 is sleeved on the bending floating material guide rod B52; the top of the bending floating connection block B46 located in the preforming station 34 is connected to a preforming lower knife assembly 35, and the top of the preforming lower knife assembly 35 is connected to a forming positioning block B53, A preforming floating block 36 is installed between the forming positioning blocks B53, and a preforming roller 361 installed on the forming positioning block B53 is provided on one side of the preforming floating block 36; the top of the bending floating connection block B46 located in the forming station 33 is connected to the forming lower knife assembly 37, and the top of the forming lower knife assembly 37 is installed with a forming floating block 38, and the top of the bending floating connection block B46 located in the forming station 33 is also connected to the forming lower knife fixed insert 54, and one side of the forming lower knife fixed insert 54 is connected to the clip forming assembly reset spring 541;

[0062] The molding lower knife assembly 37 includes a clip molding lower knife 371 and a rotating shaft A374 installed on the clip molding lower knife 371. A shaft sleeve 372 is installed at the upper hole of the clip molding lower knife 371. The shaft sleeve 372 is connected to the clip molding lower knife 371 through a rotating shaft B373.

[0063] Since the bending direction (upward) of the two wings of the ZR solder product targeted by the present invention is opposite to the U-shaped bending direction, the preforming (roller forming) and forming (clip forming) tool assemblies are installed at the lower die of the second die, and the comparison die is also adjusted accordingly;

[0064] The semi-finished product coming out of the mold 1 passes through the preforming station 34 and the forming station 33 of the mold 2 in sequence under the action of the material shifting component of the equipment to complete the bending of the two wings;

[0065] During the preforming process, the upper die moves downward, and under the action of the forming unloading insert B40, together with the floating track cover plate B48 and the unloading plate B49, the product is driven downward, and the product enters the forming positioning block B53 for positioning; after the positioning is completed, the preforming upper knife B39 continues to move downward, and the product and the preforming floating block 36 cooperate with the preforming lower knife assembly 35 to complete the preforming; after the preforming is completed, the upper die part moves upward to unload, and the preforming floating block 36 rises and floats under the action of the spring force; in the process of the bending floating connection block B46 floating up and down, the linear bushing B51 and the bending floating guide rod B52 are used for linear guidance;

[0066] When the product is formed at the forming station 33, the upper mold part moves downward under the action of the power mechanism of the equipment. When the upper mold unloading plate reaches the height of the lower mold limit column, the unloading part stops moving downward, and the product positioning is completed at the same time; the upper molding knife B47 installed on the upper knife seat continues to move downward along with the template to push the product and the molding floating block 38 downward, and under the action of the molding floating block 38, one end of the molding lower knife assembly 37 installed on the molding lower knife fixed insert 54 is propped open, so that the end contacting the product is tightened, thereby achieving the purpose of molding the product;

[0067] After the molding is completed, the upper mold part moves upward to unload and returns to the original position, and the molding lower knife assembly 37 and the molding floating block 38 return to their initial state under the action of their respective springs;

[0068] like Figure 18 and Figure 19 The product shown is after passing through mold 2.

[0069] like Figures 12 - 14 As shown, the mold three includes an inner ear bending preforming station 55, an inner ear bending forming station 56, a lower template C69, an upper template C70, and an up-and-down floating mechanism arranged at the inner ear bending forming station 56;

[0070] The main function of mold 3 is to complete the inner ear bending process of the product. This process can be completed in two steps, namely, through the inner ear bending preforming station 55 and the inner ear bending forming station 56;

[0071] The inner ear bending preforming station 55 includes a preforming lower knife 57 and a preforming upper knife C61; the inner ear bending forming station 56 includes a forming lower knife 59 and a forming upper knife C62; the upper knife fixing seat C67 is installed on the upper template C70, and the lower knife fixing seat C68 is installed on the lower template C69.

The bending floating connection block C71 and the molding floating block insert C72 are connected by a plurality of connecting springs C73. The top of the bending floating connection block C71 is connected to a bending floating material guide rod C75. A linear bushing C74 is sleeved on the bending floating material guide rod C75. The top of the bending floating connection block C71 is connected to a molding positioning block C58 and a molding lower knife 59. A molding floating block 60 is provided between the molding positioning block C58 and the molding lower knife 59.

[0073] A floating track C63, a track cover plate C64, a molding unloading insert C65 and a unloading plate C66 are provided between the lower template C69 and the upper template C70;

[0074] The molding positioning block C58 plays a role of lateral positioning during the product molding process, and is used in conjunction with the lower positioning pin for longitudinal positioning to ensure accurate product positioning, thereby ensuring the molding size of the product; the molding floating block 60 is used as a floating device to support the product during the molding process to prevent product deformation, and also helps to remove the material after molding;

[0075] After the product is delivered to the place, the upper die part moves downward, and the floating track C63 and track cover C64 of the unloading part move downward together with the product to enter the positioning process. When the limit device in the lower die limits the unloading part to move downward and the positioning is completed, the upper knife part continues to move downward and completes the molding work with the corresponding lower knife. After the molding is completed, the upper die part moves upward to unload and wait for the next molding action.

[0076] When the product is formed at the forming station, the forming float 60 moves downward with the product under the action of the forming upper knife C62. After the forming is completed, the upper mold part moves upward, and the forming float 60 recovers upward under the action of the bent floating connection block C71, the forming float insert C72, and the connecting spring C73 to assist the product demoulding, and the linear bushing C74 and the bent floating guide rod C75 are used to ensure the smooth operation of the float;

[0077] like Figure 20 and 21 The product shown is after passing through mold three;

[0078] The working principle of the present invention is as follows: The mold is combined with an upper three-power punching and forming device. The three powers of the device provide punching power for three sets of molds respectively. The ejector mechanism of the device sends the material to the material-grabbing mechanism. The material-grabbing mechanism grabs the material and sends it to the feeding mechanism. The feeding mechanism sends the material to the material-deflecting mechanism. The material-deflecting mechanism sends the material to Die 1 through the deflecting gripper to complete the processes of polarity excision, U-shaped forming, and rib separation. Then, the semi-finished product in Die 1 is pushed out of Die 1 to the discharging part by the pushing component on the power mechanism in the punching device. The motor of the discharging part conveys the product to the deflecting position of the second-stage material-deflecting mechanism, and then the material-deflecting mechanism sends it to Die 2 to complete the forming of the two wings by bending. Then, it enters Die 3 to complete the inward turning of the inner ear, and finally, the finished product is sent out of Die 3 through the deflecting gripper and enters the tube-loading mechanism for tube loading and collection.
