Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of stamping die sets, and specifically to a stamping die set for a two-way angle inclined ejection of an automobile door panel. Background Art
[0002] When stamping a car door panel, generally, a sheet metal is directly stamped into a semi-finished product through the shapes of a convex (male) die and a concave (female) die. In an existing automated stamping production line, the feeding of the sheet metal and the unloading of the semi-finished product are both completed by a manipulator. During stamping, the convex die (male die) is generally located at a lower position (to facilitate the detachment and unloading of the semi-finished product). When the sheet metal is placed on the convex die, the sheet metal will tilt to one side and fall on the convex die. In order to prevent the sheet metal from excessively sliding to one side of the convex die, a stop block is generally provided to block the sheet metal. In order to prevent the stop block from intruding between the dies, the stop block is generally arranged on the die set. Considering that the outer contour of a car door die is generally a regular rectangle, the raw sheet metal is generally cut into a rectangular plate shape, which results in a large amount of surplus material left between the protruding contour of the semi-finished product and the periphery of the semi-finished product after stamping, leading to a large amount of surplus material generated during stamping production and low utilization efficiency of the metal sheet. Summary of the Invention

[0006] Furthermore, an embedding groove one is provided at the top end of the support member, and the pressing plate can be embedded into the embedding groove one.
[0007] Furthermore, round rods one are fixedly connected to both ends of the pressing plate. Vertical grooves two are provided at the top end of the support member corresponding to the positions of the two round rods one. The round rod one is slidably inserted between the adjacent vertical groove two. A return spring is fixedly connected between the bottom end of the round rod one and the inner bottom surface of the vertical groove two. Vertical grooves one are provided at the top end of the support member corresponding to the positions of the two round rods two. The round rod two is slidably inserted between the adjacent vertical groove one.
[0008] Furthermore, a limiting module is provided at the top end position of the second inclined groove, and the limiting module is used for limiting when the diagonal brace extends out.
[0009] Furthermore, a fastener is fixedly connected to the outer side wall of one end of the diagonal brace. The limiting module includes a clamping member. A sliding groove is provided at the position near the top end of the first inclined groove inside the support member. The clamping member is slidably connected in the sliding groove. A compression spring is fixedly connected between the clamping member and the inner wall of one end of the sliding groove. One end of the clamping member can be engaged with the fastener. A pull rope is fixedly connected to the other end of the clamping member. One end of the pull rope penetrates upward to the top end position of the support member, and the top end of the pull rope is fixedly connected to the pressing plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the setting of the diagonal braces, the four diagonal braces can extend obliquely. After the diagonal braces extend, the sheet is placed on the four diagonal braces, and the sheet is adsorbed and fixed by the suction cup end. When the movable frame descends until the bottom surface of the female mold contacts the sheet, the pressing plate contacts the driving module. Subsequently, the downward movement of the movable frame drives the diagonal braces to move downward along the chute I through the driving module, causing the suction cup end to disengage from the sheet. The movable frame and the fixed frame are closed to realize the stamping of the sheet. Through the lifting and fixing of the sheet by the diagonal braces and the oblique retraction setting of the diagonal braces when the movable frame moves downward, the lifting and fixing of irregular sheets can be realized, and at the same time, it can be avoided that the diagonal braces invade the stamping range of the male and female molds, so that the outer contour of the sheet can be cut according to the stamping shape before stamping, thereby reducing the surplus material part at the edge of the sheet, reducing the amount of surplus material after stamping, and at the same time, it can also make the arrangement of the sheet more compact during cutting before stamping, improving the utilization efficiency of the metal plate; 2. Through the setting of the limiting module, when the diagonal braces extend, the clamping part and the fastening part are clamped together, thereby restricting the position of the diagonal braces and preventing the diagonal braces from retracting. Through the setting of the pressing wheel, when the pressing plate moves downward, the pressing wheel first inserts into the middle seam, thereby pushing down the top end of the pull rope, making the top end of the pull rope bend into a U shape. The pull rope is tightened to drive the clamping part to retract into the chute, causing the clamping part and the fastening part to disengage. Subsequently, the pressing plate moves downward and fits with the pressing plate to drive the pressing plate to move downward, realizing the limitation of the diagonal braces when the diagonal braces extend.

Specific embodiments
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0018] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a two-way angle inclined top stamping die carrier for an automobile door panel includes a fixed frame 100 and a movable frame 200. A sub-mold can be installed in the fixed frame 100, and a mother-mold can be installed in the movable frame 200. It further includes a support mechanism 300. There are two support mechanisms 300 respectively, and the two support mechanisms 300 are respectively installed at both ends of the fixed frame 100. The support mechanism 300 includes a support member 310. First inclined grooves 311 are formed inside both ends of the support member 310. Inclined struts 320 are slidably sleeved in the first inclined grooves 311. One end of the inclined strut 320 is provided with a suction cup end 321, and the other end of the inclined strut 320 is fixedly connected to an air pipe 350. Air nozzles 360 are fixedly connected to both ends of one side wall of the support member 310. One end of the air pipe 350 is fixedly communicated with the adjacent air nozzle 360. A driving module 330 is arranged at the top of the support member 310. The driving module 330 is used to drive the inclined strut 320 to slide along the first inclined groove 311. The movable frame 200 can be used to drive the driving module 330. End grooves 210 are formed at both ends of the movable frame 200, and pressing plates 220 are fixedly connected to the inner walls of the end grooves 210.
[0019] Specifically, when the fixed frame 100 and the movable frame 200 are in a separated state, the four diagonal braces 320 are in an extended state. The external manipulator horizontally places the sheet on the four diagonal braces 320, and adsorbs and fixes the sheet through the suction cup end 321. Subsequently, the movable frame 200 descends. When the bottom surface of the female mold contacts the sheet during the descent of the movable frame 200, the pressing plate 220 contacts the driving module 330. Subsequently, the downward movement of the movable frame 200 drives the diagonal braces 320 to move downward along the first inclined groove 311 through the driving module 330, causing the suction cup end 321 to disengage from the sheet. The movable frame 200 and the fixed frame 100 are closed to achieve stamping of the sheet. When the movable frame 200 moves upward, the movable frame 200 gradually releases the extrusion on the driving module 330, causing the diagonal braces 320 to move upward and extend. Through the lifting and fixing of the sheet by the diagonal braces 320 and the inclined retraction setting of the diagonal braces 320 during the downward movement of the movable frame 200, the lifting and fixing of irregular sheets can be realized, and at the same time, it can be avoided that the diagonal braces 320 invade the stamping range of the mother and son molds. Thus, the outer contour of the sheet can be cut according to the stamping shape before stamping, reducing the surplus material part at the edge of the sheet, reducing the amount of surplus material after stamping and cutting, and also making the arrangement of the sheet more compact during cutting before stamping, improving the utilization efficiency of the metal plate.
[0020] Embodiment 1
[0021] As Figures 5 to 9 shown, in this embodiment, the driving module 330 includes a pressing plate 331, a second round rod 335, and a sliding seat 337. The pressing plate 331 is used to contact the pressing plate 220. There are two second round rods 335, and the two second round rods 335 are respectively fixed at both ends of the pressing plate 331. The second round rod 335 is slidably sleeved with the support member 310. There are two sliding seats 337, and the two sliding seats 337 correspond to the two diagonal braces 320 one by one. The sliding seat 337 is fixedly connected to the outer side wall of the other end of the corresponding diagonal brace 320. The inner walls on both sides of the first inclined groove 311 are both provided with second inclined grooves 312, and the sliding seat 337 is slidably connected to the second inclined groove 312. A push rod 336 is rotatably connected between the bottom end of the sliding seat 337 and the second round rod 335. An embedding groove 315 is provided at the top end of the support member 310, and the pressing plate 331 can be embedded into the embedding groove 315. Round rods 333 are fixedly connected to both ends of the pressing plate 331. Vertical grooves 317 are provided at the top end of the support member 310 corresponding to the two round rods 333. The round rod 333 is slidably inserted between the adjacent vertical groove 317. A return spring 334 is fixedly connected between the bottom end of the round rod 333 and the inner bottom surface of the vertical groove 317. Vertical grooves 313 are provided at the top end of the support member 310 corresponding to the two second round rods 335. The second round rod 335 is slidably inserted between the adjacent vertical groove 313.
[0022] In this embodiment, when the diagonal brace 320 is in the extended state, the angle between the push rod 336 and the second inclined groove 312 is an obtuse angle. Therefore, when the top end of the push rod 336 moves downward and the push rod 336 squeezes and pushes the slide block 337 to slide downward along the second inclined groove 312, during the downward movement of the push rod 336, the push rod 336 gradually deflects to the vertical state. As a result, when the push rod 336 moves downward, the descending distance of the bottom end of the push rod 336 is greater than the descending distance of the top end of the push rod 336. That is, when the pressing plate 220 pushes the pressing block 331 to drive the diagonal brace 320 to move downward, the downward movement speed of the diagonal brace 320 is greater than the downward movement speed of the pressing plate 220, which facilitates the separation between the top end of the diagonal brace 320 and the plate when the plate deforms, avoiding continuous contact between the diagonal brace 320 and the plate. Through the arrangement of the return spring 334, the return spring 334 is used to drive the pressing block 331 to rebound upward.
[0023] Embodiment 2
[0024] On the basis of Embodiment 1, in order to make up for the problem that after the plate is placed on the four diagonal braces 320 in Embodiment 1, the diagonal braces 320 retract under the weight of the plate, thus affecting the supporting effect of the diagonal braces 320 on the plate.
[0025] As Figures 7 to 9 shown, in this embodiment, a limiting module 340 is provided at the top position of the second inclined groove 312. The limiting module 340 is used to limit the diagonal brace 320 when it extends. A fastener 323 is fixedly connected to the outer side wall of one end of the diagonal brace 320. The limiting module 340 includes a clamping member 341. A sliding groove 314 is formed at the top position of the support member 310 near the first inclined groove 311. The clamping member 341 is slidably connected in the sliding groove 314. A compression spring 342 is fixedly connected between the clamping member 341 and the inner wall of one end of the sliding groove 314. One end of the clamping member 341 can be engaged with the fastener 323. A pull rope 343 is fixedly connected to the other end of the clamping member 341. One end of the pull rope 343 penetrates upward to the top position of the support member 310. The top end of the pull rope 343 is fixedly connected to the pressing block 331. A middle slit 332 is formed at the middle position of the pressing block 331. One end of the pull rope 343 penetrates through one side of the pressing block 331 and is fixedly connected to the other side of the pressing block 331. Pressing wheels 221 are fixedly installed at both ends of the bottom surface of the pressing plate 220 corresponding to the positions of the middle slit 332. Embedding grooves two 316 are formed at the top of the support member 310 corresponding to the positions of the two pressing wheels 221. The pressing wheels 221 can be inserted into the embedding grooves two 316.
[0026] During specific implementation, when the diagonal brace 320 extends, the clamping member 341 is clamped with the fastener 323, thereby restricting the position of the diagonal brace 320 and preventing the diagonal brace 320 from retracting. Through the arrangement of the pressing wheel 221, when the pressing plate 220 moves downward, the pressing wheel 221 first inserts into the middle seam 332, thereby pushing down the top end of the pull rope 343, causing the top end of the pull rope 343 to be bent in a U shape. The pull rope 343 is tightened to drive the clamping member 341 to retract into the sliding groove 314, causing the separation between the clamping member 341 and the fastener 323. Subsequently, the pressing plate 220 moves downward to fit with the pressing plate 331 and drives the pressing plate 331 to move downward, realizing the limitation of the diagonal brace 320 when the diagonal brace 320 extends.
[0027] As Figures 1 to 9 shown, in this embodiment, a branch pipe 361 is fixedly connected to the middle position of the air nozzle 360, a solenoid valve 362 is installed at the middle position of the branch pipe 361, an outer fixing ring 322 is fixedly connected to the top end position of the diagonal brace 320, the outer fixing ring 322 is located outside the suction cup end 321, guide posts are fixedly connected to the four vertex positions of the fixing frame 100, and guide sleeves matching the guide posts are fixedly connected to the four vertex positions of the movable frame 200.
[0028] During specific implementation, through the arrangement of the branch pipe 361 and the solenoid valve 362, the air nozzle 360 is connected to the external negative pressure device. When the movable frame 200 moves downward, the solenoid valve 362 opens, thereby gradually restoring the air pressure inside the diagonal brace 320. When the movable frame 200 moves upward, the solenoid valve 362 closes, causing a negative pressure to be formed inside the diagonal brace 320. Since the suction cup end 321 is made of a relatively soft material and is easily deformed to fit the plate, through the arrangement of the outer fixing ring 322, it is convenient to support the plate.
[0029] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
