[0002] The processing of aluminum alloy door and window panels is a delicate and multi-step process, which mainly includes material preparation, cutting, machining (such as drilling, milling, punching), bending, straightening and finishing, surface treatment and final assembly connection.

[0003] At present, in the processing of aluminum alloy door and window panels, aluminum sheet parts are mostly stamped through continuous stamping dies. Door and window profiles need to be bent and stamped before edge opening to meet the processing technology.

[0004] However, in actual application, traditional molds can only perform stamping and hole-punching operations separately. To complete these two steps, two or more sets of molds are often required, which not only increases production costs but also reduces processing efficiency.

The push plate 42 realizes pushing and resetting through the pushing and resetting springs 421 provided on both sides in cooperation with the guide pillars. This is a conventional setting of the mold in this field and will not be explained again.

[0051] Wherein, a lower punch plate 9 is arranged at the bottom of the push plate 42 .

The guide arm 2 6 corresponds to the guide arm 1 5, and is correspondingly fitted and connected with the guide bevel groove 71 set in the middle of the guide block 7. When the upper mold 2 drives the guide block 7 to punch downward, the guide bevel groove 71 drives the guide arm 2 6, that is, the side punch slider 10 to move laterally.

[0058] Furthermore, punch three 82 is fixed, and punch one 8 and punch two 81 are movable, wherein punch one 8 and punch two 81 are provided with convex rings 30 on their inner sides, and annular grooves 32 for fitting with the convex rings 30 are provided on the outer walls of punch two 81 and punch three 82, and the annular grooves 32 and the convex rings 30 are connected by spring three 31, so that punch one 8 is limitedly slidably installed on the outer wall of punch two 81, and punch two 81 is limitedly slidably installed on the outer wall of punch three 82.

[0059] At the same time, a limiting groove 1 23 and a limiting groove 231 are respectively provided at one end of the punch 1 8 and the punch 2 81 facing the support seat 11. The width of the limiting groove 1 23 is twice the width of the limiting groove 231, and in a natural state, the inner walls of the limiting grooves 1 23 and 231 are aligned on one side.

[0060] Furthermore, a short connecting rod 161 is sleeved and installed on one side of the middle part of the punch three 82, a sleeve 21 is installed in the middle part of one end of the short connecting rod 161, and a convex plate 22 is vertically installed on the outer wall of the sleeve 21, wherein the outer wall of the sleeve 21 fits with the inner wall of the punch two 81, and the cross-section of the convex plate 22 is flush with the end faces of the punch two 81 and the punch one 8 respectively.

[0061] In a natural state, the convex plate 22 is inclined with the sleeve 21, and the convex plate 22 is away from the limiting groove 1 23 and the limiting groove 231, and the convex plate 22 is in contact with the baffle 24 provided on one side of the punch 1 8.

[0062] Furthermore, one end of the short connecting rod 161 is limitedly connected to the long connecting rod 16 through the guide rod 20, and a screw rod 19 is screwed to the middle of the short connecting rod 161, and the other end of the screw rod 19 passes through the long connecting rod 16 and comes out from the other end thereof.

[0063] A strip groove 33 is provided at one end of the long connecting rod 16, and a rolling pin 18 is fitted and connected in the strip groove 33. One end of the rolling pin 18 is rotatably connected to a block 181, and the block 181 is limitedly installed on the turntable 13, and a through hole is provided in the middle of the rolling pin 18, and a wire rod 19 passes through the through hole. One end of the wire rod 19 passes through the outer wall of the long connecting rod 16 and is connected to a clamping joint 191, and the clamping joint 191 is rotatably installed on the outer wall of the long connecting rod 16.

[0064] Specifically, a pair of rolling pin slots 131 are symmetrically provided on the turntable 13, a block 181 is slidably installed in the rolling pin slot 131, and the block 181 is connected to the rolling pin slot 131 through a spring 1311 to enable the block 181 to move and reset.

[0065] Furthermore, a mounting seat 25 is provided in the middle of the turntable 13, and a handle member 15 is rotatably installed on the upper part of the mounting seat 25. One end of the handle member 15 extends into the interior of the mounting seat 25 and is connected to an umbrella tooth 151. Both sides of the umbrella tooth 151 are connected to a pair of umbrella teeth 261 through gear meshing. One end of the umbrella tooth 261 is connected to a cross groove drive head 26 through a shaft. The cross groove drive head 26 is rotatably installed on both sides of the outer wall of the mounting seat 25, and the cross groove drive head 26 corresponds to each long connecting rod 16 respectively.

[0066] Furthermore, when the handle member 15 is rotated to a central vertical position, the cross slot drive heads 26 on both sides are horizontally aligned, and the long connecting rod 16 rotates synchronously and is clamped with the cross slot drive head 26 through the clamping joint 191. At this time, the screw member 19 is adjusted by rotating the handle member 15.

[0067] The cross groove drive head 26 is provided with a cross groove body, which can effectively engage with the clamping joint 191.

[0068] Reference Fig.16 One side of the inner wall of the turntable 13 is connected to a limiting plate 28 through a spring 281. The limiting plate 28 is installed on the inner side of the turntable 13 for limiting sliding, and the limiting plate 28 is installed in a limiting groove 27 opened on the inner wall of the side punch slider 10. The cross-section of the limiting groove 27 is in the shape of a gold ingot, and the left, middle and right sides thereof are all provided with upwardly concave grooves, and each groove corresponds to a different rotation state of the handle member 15, and in a natural state, the limiting plate 28 is tightened by the spring 281 to be embedded in the groove opened on the inner wall of the limiting groove 27.

[0069] Reference Fig.17 One end of the support seat 11 is limitedly slidably installed inside the slide groove 14, and the upper and lower walls inside the slide groove 14 are provided with a wave-shaped groove 141, and an arc-shaped spring leaf 111 is symmetrically installed on the inner side of the support seat 11, and the arc-shaped spring leaf 111 is arched in an arc shape and fits and squeezes with the groove of the wave-shaped groove 141, and when the support seat 11 moves, the arc-shaped spring leaf 111 is squeezed and deformed.

[0070] In the present embodiment, a corresponding number of punches are assembled onto the upper die 2, and correspondingly, a corresponding number of concave dies are assembled into the lower die 1, wherein the specific installation method and sequence of the punches and concave dies of the continuous stamping die are already existing technologies, and the punches and concave dies of different sizes and functions are configured and installed by on-site operators, which is a routine operation in this technical field and is easy to understand intuitively, so it will not be elaborated on.

[0071] The material sheet 101 is fed into the lower die 1 for continuous stamping and forming, and when the material passes through a bending and punching die 3, a synchronous bending and punching process is performed.

[0072] In a more general sense, the upper die 2 drives the guide block 7 and the bending punch 72 downward, and the bending punch 72 punches and bends the material on the bending die 301. Simultaneously, the guide block 7 drives the punch 8 to push and punch the bent sheet surface sideways, and the lower punch 9 simultaneously performs secondary bending on the sheet.

[0073] Among them, the guide block 7 is provided with a corresponding guide bevel 71, and the guide bevel 71 guides the guide arm 1 5 and the guide arm 2 6. During the downward process of the guide block 7, the guide block 7 converts its vertical displacement into the horizontal displacement of the side push die 4 and the side punch slider 10, so that it moves toward the bending punching die 3, and then the push plate 42 provided on the side push die 4 is squeezed with the outer wall of the downward bending punch plate 72, and at this time, the push reset spring 421 is compressed and deformed;

[0074] At the same time, the punch 8 provided in the side punching slider 10 continues to push the front top sideways, and after passing through the push plate 42 and the bending punch plate 72 in sequence, the side of the material plate 101 is punched, wherein the corresponding punching groove 302 is opened on the bending die 301.

[0075] The push plate 42 and the bending punch plate 72 are provided with corresponding notches in the middle to allow the punch 8 to pass through.

[0076] In actual application, when it is necessary to change the hole size of the plate, in the stopped state, pull the handle member 15 to rotate, and the handle member 15 realizes fixed-point and fixed-distance rotation through the resettable limit plate 28 and the limit groove three 27, wherein the limit groove three 27 is in the shape of a gold ingot, and additional upwardly concave grooves are opened on the left, middle and right sides, and each groove corresponds to a different rotation state of the handle member 15, and after a single rotation, the limit plate 28 is tightened by the spring two 281 to be embedded in the corresponding groove of the limit groove three 27, so as to satisfy the fixed-point deflection displacement function from one groove to another.

[0077] Then, when the handle member 15 rotates synchronously with the turntable 13, under the influence of the limiting groove three 27, the handle member 15 is in a centered vertical state, and a pair of rolling pins 18 arranged on the turntable 13 rotate synchronously to a horizontal and flush state, and the long connecting rod 16 and the short connecting rod 161 connected to the rolling pin 18 are deflected synchronously, and the deflection displacement is converted into the deflection displacement of the sleeve 21, so that the sleeve 21 is deflected synchronously with the convex plate 22. At this time, the convex plate 22 is separated from the baffle 24 set on the punch 8, and deflected and moved to a limiting groove 23 of the punch 8. At this time, the cross section of the baffle 24 is no longer in contact with the punch 8, and the punch 8 can be telescopically moved.

[0078] Specifically, after the adjustment of the handle member 15 is completed, the originally fixed punch 8 is unlocked to realize the function of telescopic reset, and in a single punching operation, the punch 8 will retract due to the reverse force after contacting the material, and the punching operation will be realized synchronously by the punch 2 81 and the punch 3 82. At this time, the punch that is in direct contact with the plate is the punch 2 81, so the punching size changes.

[0079] Similarly, after continuing to pull the handle member 15, the deflection amount of the protruding plate 22 increases accordingly. At this time, the protruding plate 22 moves to the overlapping area of ​​the limiting groove 1 23 and the limiting groove 2 231. At this time, the protruding plate 22 synchronously disengages from the punch 1 8 and the punch 2 81. Conversely, during the punching operation, the punch 1 8 and the punch 2 81 will retreat due to the reverse force after contacting the material. At this time, the punch that is in direct contact is the punch 3 82.

[0080] Punch 1 8 and punch 2 81 are compressed and returned to the top by spring 3 31 to realize the mobile reset function.

[0081] In the natural state, the handle member 15 is at the outermost side, that is, the limiting plate 28 is at the outermost part of the limiting groove three 27. At this time, the convex plate 22 respectively conflicts with the cross-sections of the punch one 8 and the punch two 81, and fits against the side wall of the baffle 24. Relatively speaking, during the punching operation, the punch one 8 and the punch two 81 are both in a fixed state.

[0082] Due to the shape of the limiting groove 3 27, the handle 15 can only have three single deflection states: left tilt, right tilt, and center vertical, thereby ensuring the accuracy and stability of the adjustment process.

[0083] Among them, it is worth noting that since the position of the short connecting rod 161 is fixed, the long connecting rod 16 will convert the rotational displacement at the end into the relative horizontal position and rotational displacement of the rolling pin 18 during the deflection process, wherein the horizontal displacement can be effectively offset by the block 181 connected to the rolling pin 18, and the block 181 realizes the lateral displacement reset function through the spring 1311.

[0084] In actual application, when it is necessary to change the hole position of the plate, in the shutdown state, the handle member 15 is deflected to a centered vertical state. At this time, a pair of rolling pins 18 arranged on the turntable 13 are synchronously rotated to a horizontal and flush state. Synchronously, the long connecting rod 16 is deflected and is in the same horizontal position with the axis of the turntable 13 and the rolling pins 18. At this time, the clamping joint 191 arranged on the long connecting rod 16 is matched with the cross groove driving head 26 arranged on the outside of the mounting seat 25. At this time, by axially rotating the handle member 15, the handle member 15 drives the bevel gear 151 arranged inside the mounting seat 25 to rotate, and the bevel gear 151 drives the corresponding cross groove driving heads 26 on both sides to rotate, and drives the clamping joint 191 to synchronously drive the screw member 19 to rotate. The screw member 19 rotates to drive the short connecting rod 161 to move through the threaded rotation, and the support seat 11 is displaced at the same time.

[0085] The upper and lower ends of the support seat 11 are symmetrically installed with arc-shaped spring leaves 111. The arc-shaped spring leaves 111 are arched in an arc shape and fit into the concave part of the wavy groove 141 for extrusion and clamping. When the support seat 11 moves, the arc-shaped spring leaves 111 are squeezed and deformed and fit into the wavy groove 141, so that resistance is generated during movement and stillness to ensure operational stability. During the movement of the support seat 11, the arc-shaped spring leaves 111 can provide good movement feedback and adjustment accuracy.

[0086] Among them, it is worth noting that a rubber gasket is provided at the rotational connection between the handle member 15 and the mounting seat 25 to increase the rotational damping force and increase the rotational viscosity to improve the smoothness of the use of the handle member 15. Among them, the rubber gasket is a commonly used accessory on the market, and its principle and assembly method will not be explained again.

[0087] Among them, it is worth noting that the side push mold 4 realizes the side push reset function by the reset base 41, the push plate 42 realizes the side push reset function by the push reset spring 421, and the side punch slider 10 realizes the side punch reset function by the slider part 29 and the stamping reset spring 291.
