Description
Technical Field
[0001] The present application relates to the field of flanging dies, and in particular to a double-floating flanging die. Background Art
[0002] A flanging die is a die that turns the edge of a flat or curved part of a blank along a certain curve to form a straight edge. In workpiece processing, the use of a flanging die can make the edge of the workpiece or the inner wall of the through hole smooth, and is an important process in the workpiece processing procedure.
[0003] Existing automotive cylinder head gaskets are made of composite materials. Stainless steel is used for the face and base sheets, and a vulcanized plate is used for the center sheet. The face and base sheets are bonded to either side of the center sheet. The face, center, and base sheets are punched into specific shapes using stamping equipment. Through holes are positioned correspondingly on each sheet. After the face, center, and base sheets are bonded together to form the cylinder gasket, multiple through holes are opened in the center. During processing, the user places the cylinder gasket between an upper and lower mold plate. A power mechanism drives the upper mold plate downward, allowing it to perform a flanging stamping on the upper surface of the cylinder gasket. The user then flips the cylinder gasket over, allowing the upper mold plate to stamp the other side.
[0004] The above-mentioned related technical solutions have the following defects: when the cylinder gasket is heavy and large in size, the process of flipping the cylinder gasket is time-consuming and labor-intensive, resulting in a long processing time and low processing efficiency. Utility Model Content
[0005] In order to improve the efficiency of cylinder gasket processing, the present application provides a double floating flanging die.
[0006] The double floating flanging die provided in this application adopts the following technical solution:
[0007] A double floating flanging die comprises an upper die plate and a lower die plate, the upper die plate comprises an upper flanging die base, an upper flanging die cylinder mouth punch and an upper floating plate, the lower die plate comprises a lower flanging die base, an upper flanging die cylinder mouth punch and a lower floating plate, the upper flanging die base, the upper floating plate, the lower flanging die base and the lower floating plate are parallel to each other, the upper floating plate is slidably connected to the upper flanging die base, the lower floating plate is slidably connected to the lower flanging die base, the upper flanging die cylinder mouth punch passes through the upper floating plate and is fixed on the upper flanging die base, the lower flanging die cylinder mouth punch passes through the lower floating plate and is fixed on the lower flanging die base.
[0008] By adopting the above technical solution, an upper floating plate is set on the upper die base of the flanging, and a lower floating plate is set on the lower die base of the flanging. When the upper die plate and the lower die plate jointly extrude the workpiece, the upper floating plate and the lower floating plate slide at the same time, so that the cylinder mouth punch of the flanging upper die extrude the upper surface of the workpiece, and the cylinder mouth punch of the flanging lower die extrude the lower surface of the workpiece, so that the through holes on the upper and lower surfaces of the workpiece can be flanging processed, and the inner walls on both sides of the through hole of the workpiece are smoother. The step of flipping the workpiece is omitted during the processing, which can improve the processing efficiency.
[0009] Optionally, the flanging upper die base is provided with a flanging upper die side punch, the flanging upper die side punch is a closed frame structure, and the upper floating plate is arranged in the space surrounded by the flanging upper die side punch.
[0010] By adopting the above technical solution, by arranging a flanging upper die side punch on the flanging upper die base, when the upper die plate and the lower die plate jointly extrude the workpiece, the flanging upper die side punch can extrude the outer surface of the workpiece, thereby making the outer edge of the workpiece smooth.
[0011] Optionally, an upper spring is provided on the upper floating plate, the upper spring is perpendicular to the upper floating plate, one end of the upper spring is connected to the upper floating plate, and the other end is connected to the flanging upper die base.
[0012] By adopting the above technical solution, an upper spring is set on the upper floating plate, so that the upper spring abuts against the upper floating plate, thereby keeping the upper floating plate flush with the side punch of the flanging upper die. When the upper die plate squeezes the workpiece, the upper floating plate can first abut against the workpiece, reducing the chance of the workpiece slipping in the horizontal direction.
[0013] Optionally, a flanging upper mold clamping plate is provided between the flanging upper mold base and the upper floating plate, the flanging upper mold clamping plate is fixed on the flanging upper mold base, a mounting hole is opened on the flanging upper mold clamping plate, and the upper side spring is arranged in the mounting hole.
[0014] By adopting the above technical solution, by arranging a flanging upper die clamp on the flanging upper die base, when the upper floating plate abuts against the flanging upper die clamp, the upper spring contracts and is completely received into the mounting hole, and the flanging upper die clamp supports the upper floating plate, so that the upper floating plate can maintain a position parallel to the flanging upper die base.
[0015] Optionally, the side punch of the flanging upper die is detachably connected to the flanging upper die clamping plate.
[0016] By adopting the above technical solution, by making the side punch of the flanging upper die detachable and connected to the flanging upper die clamping plate, the user can install the side punches of the flanging upper die of different widths on the flanging upper die clamping plate, thereby enabling the upper die plate to process workpieces of different sizes.
[0017] Optionally, a plurality of guide columns are provided on the flanging lower die base, and matching holes are opened on the flanging upper die clamping plate. The positions and sizes of the matching holes correspond one-to-one to the guide columns. The lower ends of the guide columns are fixed on the flanging lower die base, and the upper ends are used to be inserted into the matching holes.
[0018] By adopting the above technical solution, by arranging a guide column on the flanging lower die base, when the upper template and the lower template jointly extrude the workpiece, the upper end of the guide column can be inserted into the matching hole. The guide column plays a positioning effect, which can reduce the probability of horizontal slippage of the upper template relative to the lower template and improve the processing quality.
[0019] Optionally, a plurality of positioning columns are provided on the flanging lower die base, the lower ends of the positioning columns are fixed on the flanging lower die base, and the upper ends thereof pass through the lower floating plate.
[0020] By adopting the above technical solution, a plurality of positioning columns are arranged on the flanging lower die base, and the positioning columns are arranged through the lower floating plate. Positioning holes corresponding to the positioning columns are opened on the workpiece. When the workpiece is placed between the upper template and the lower template, the workpiece is pressed on the lower floating plate, causing the lower floating plate to fall, and the positioning columns can be inserted into the positioning holes, thereby clamping the workpiece on the lower template, reducing the chance of horizontal slippage of the workpiece on the lower template and improving the processing quality.
[0021] Optionally, the upper floating plate is detachably connected to the upper flanging die base, and the lower floating plate is detachably connected to the lower flanging die base.
[0022] By adopting the above technical solution, the user can install upper floating plates of different sizes and thicknesses on the flanging upper die base, and install lower floating plates of different sizes and thicknesses on the flanging lower die base. When the thicknesses of the two side pieces and the bottom piece of the cylinder gasket to be processed are different, the upper template and the lower template can be used to stamp on the side pieces and bottom pieces of different thicknesses respectively, reducing the chance of the flanging upper die cylinder mouth punch and the flanging lower die cylinder mouth punch affecting the center piece.
[0023] In summary, the beneficial technical effects of this application are:
[0024] 1. By arranging an upper floating plate on the upper die base of the flanging and a lower floating plate on the lower die base of the flanging, when the upper die plate and the lower die plate jointly extrude the workpiece, the upper floating plate and the lower floating plate slide simultaneously, so that the punch of the cylinder port of the flanging die extrude the upper surface of the workpiece, and the punch of the cylinder port of the flanging die extrude the lower surface of the workpiece, so that the through-holes on both the upper and lower surfaces of the workpiece can be flanging-processed, making the inner walls on both sides of the through-hole of the workpiece smoother, eliminating the step of flipping the workpiece during the processing, and improving the processing efficiency;
[0025] 2. By arranging a flanging upper die side punch on the flanging upper die base, when the upper die plate and the lower die plate jointly extrude the workpiece, the flanging upper die side punch can extrude the outer surface of the workpiece, thereby making the outer edge of the workpiece flat;
[0026] 3. By setting a guide column on the flanging lower die base, when the upper die plate and the lower die plate jointly extrude the workpiece, the upper end of the guide column can be inserted into the matching hole.

[0035] The present application is further described in detail below with reference to the accompanying drawings.
[0036] The present application embodiment discloses a double floating flanging die, referring to Figure 1 and Figure 2, including an upper template 1 and a lower template 2, the upper template 1 includes a flanging upper die base 11, a flanging upper die side punch 15 and an upper floating plate 13, the lower template 2 includes a flanging lower die base 21, a flanging lower die cylinder mouth punch 22 and a lower floating plate 23, the flanging upper die base 11, the upper floating plate 13, the flanging lower die base 21 and the lower floating plate 23 are arranged parallel to each other, the flanging upper die base 11 is located above the flanging lower die base 21, the flanging upper die side punch 15 is a frame structure, the flanging upper die side punch 15 and the upper floating plate 13 are arranged on one side surface of the flanging upper die base 11 close to the flanging lower die base 21, the flanging upper die side punch 15 is fixed on the flanging upper die base 11, the upper floating plate 13 is arranged in the space surrounded by the flanging upper die side punch 15, and the upper floating plate 13 is slidably connected to the flanging upper die base 11. The flanging lower die cylinder mouth punch 22 and the lower floating plate 23 are connected to the side of the flanging lower die base 21 close to the flanging upper die base 11. The flanging lower die cylinder mouth punch 22 is fixedly connected to the flanging lower die base 21, and the lower floating plate 23 is slidably connected to the flanging lower die base 21.
[0037] Reference Figure 3 、 Figure 4 and Figure 5 , the user places the workpiece to be punched between the upper template 1 and the lower template 2, and uses the hydraulic cylinder to drive the upper template 1 to move toward the side close to the lower template 2, so that the upper template 1 is pressed vertically downward, so that the upper template 1 and the lower template 2 squeeze the workpiece together. When the upper template 1 and the lower template 2 squeeze the workpiece, the upper floating plate 13 and the lower floating plate 23 slide at the same time, so that the workpiece can slide relative to the upper template 1 and the lower template 2 at the same time, thereby making the punching effect of the upper and lower sides of the workpiece better. When the upper template 1 and the lower template 2 squeeze the workpiece, the side punch 15 of the flanging upper die can punch the upper edge of the workpiece to make the edge of the upper surface of the workpiece neat, and the cylinder punch 22 of the flanging lower die punches the through hole on the bottom surface of the workpiece to make the edge of the through hole on the bottom surface of the workpiece neat. The stamping process can meet more processing requirements, and there is no need to set the workpieces in different processing positions respectively, reducing the steps of flipping the workpiece and improving processing efficiency.

The user can adjust the shape of the flanging upper die side punch 15 according to the shape of the workpiece to be processed.
[0039] Reference Figure 1The upper floating plate 13 is provided with a plurality of upper springs 131, which are perpendicular to the upper floating plate 13. One end of the upper spring 131 is fixed to the upper floating plate 13, and the other end is fixed to the upper flanging die base 11.

As the upper floating plate 13 slides, the punches 12 extend through the central through-holes in the upper floating plate 13 and engage the workpiece.
[0041] Reference Figure 1 The upper die holder 11 is provided with a flanging die clamping plate 14, which is positioned between the upper floating plate 13 and the upper die holder 11. The flanging die clamping plate 14 has a plurality of mounting holes 142, and the upper springs 131 are positioned in the mounting holes 142. When the upper floating plate 13 is pressed against the workpiece surface, the upper floating plate 13 can slide and abut against the flanging die clamping plate 14, and the flanging die side punch 15 in the upper die plate 1 can then punch the workpiece.
[0042] Reference Figure 1 The lower template 2 is provided with a plurality of guide posts 24. The guide posts 24 are perpendicular to the flanging lower die base 21. The lower ends of the guide posts 24 are connected to the flanging lower die base 21, and the upper ends are detachably connected to the upper template 1. The upper template 1 is provided with matching holes 141. The matching holes 141 can be provided on the flanging upper die clamping plate 14 or on the side punch 15 of the flanging upper die. When the upper template 1 and the lower template 2 jointly extrude the workpiece, the upper ends of the guide posts 24 can be inserted into the matching holes 141, thereby enabling the upper template 1 and the lower template 2 to slide along the length direction of the guide posts 24, reducing the probability of the upper template 1 moving horizontally relative to the lower template 2, and improving the workpiece processing quality.
[0043] Reference Figure 6 A plurality of positioning posts 3 are provided on the flanging lower die base 21. The positioning posts 3 are perpendicular to the flanging lower die base 21. The lower ends of the positioning posts 3 are fixed on the flanging lower die base 21, and the upper ends pass through the lower floating plate 23. When the workpiece to be processed is placed on the lower floating plate 23, through holes corresponding to the positions and sizes of the plurality of positioning posts 3 are processed on the workpiece to be processed. The positioning posts 3 can be inserted into the through holes of the workpiece to be processed, thereby positioning the workpiece, reducing the probability of horizontal slippage of the workpiece on the lower template 2, and allowing the multiple punches on the upper template 1 and the lower template 2 to fall on the predetermined positions on the workpiece, thereby improving the workpiece processing quality.
