Description

Technical Field

[0001] The present invention relates to the field of stamping, and in particular, to a single-power side shaping die for a flanged workpiece and a stamping method using the same. Background Art

[0002] During automobile assembly production, some components need to be subjected to negative-angle flanging and shaping operations to meet the requirements of automobile assembly.

[0003] Currently, in the industry, shaping mechanisms located on both sides of the workpiece are usually used to extrude the workpiece, thereby achieving side shaping of the part. The shaping mechanisms on both sides are respectively driven by two power sources. However, due to the flanging of the workpiece, during the process of approaching the workpiece, the shaping mechanisms on both sides may interfere with the flanging of the workpiece, resulting in the failure of workpiece shaping. Summary of the Invention

[0004] The purpose of the present invention is to provide a single-power side shaping die for a flanged workpiece. The single-power side shaping die for a flanged workpiece is provided with a shaping block and a guiding block. Under the action of the guiding block, the shaping block descends along an inclined direction while shaping the workpiece, which can effectively avoid the problem of interference between the shaping block and the workpiece.

[0005] To achieve the above purpose, the present invention provides a single-power side shaping die for a flanged workpiece, including a punch fixedly arranged below, a fixed pressure block located directly above the punch, liftable shaping blocks respectively located on both sides of the fixed pressure block, and a fixedly arranged guiding block cooperating with the shaping blocks. An inclined guiding groove is arranged on the side of the guiding block facing the shaping block, and the shaping block slides along the guiding groove to achieve lifting and lowering;

[0006] The two side surfaces of the punch are set as curved surfaces that are consistent with the profile of the workpiece. The shaping surface of the shaping block is parallel to the shaping surface of the punch, and the guiding groove is parallel to the shaping surface of the shaping block.

[0007] Preferably, the single-power side shaping die for a flanged workpiece further includes a second driving mechanism that can act on the shaping block.

[0008] Preferably, the second driving mechanism includes a second driving member, a second pressure block, and a pressure plate connecting the second driving member and the second pressure block. The second pressure block and the second driving member are respectively located on both sides of the pressure plate.

[0009] Preferably, the single-power side shaping die for a flanged workpiece further includes a first driving member that can act on the fixed pressure block.

[0010] Preferably, the first driving member is fixedly connected to the pressure plate. The pressure plate is slidably connected to the fixed pressure block through a limiting rod, and an elastic compressible member is arranged between the pressure plate and the fixed pressure block.

[0011] Preferably, the lower end surface of the fixed pressing block is lower than the lower end surface of the second pressing block.

[0012] Preferably, the pressure plate is provided with a through hole, and the elastically compressible member is disposed in the through hole.

[0013] Preferably, the single-power side shaping die for flanged workpieces further includes a return spring for jacking up the shaping block, and the return spring is located below the shaping block.

[0014] The present invention also provides a stamping method using the single-power side shaping die for flanged workpieces, including:

[0015] Step 1: Place the workpiece on the punch, and the fixed pressing block presses down to clamp the workpiece against the punch.

[0016] Step 2: The shaping block slides down along the guiding groove to shape the side surface of the workpiece.

[0017] Step 3: The shaping block slides up along the guiding groove, and the fixed pressing block slides up.

[0018] Step 4: Take out the workpiece.

[0019] Preferably, in Step 4, the workpiece is taken out from the side of the punch.

[0020] According to the above technical solution, the side walls on both sides of the workpiece of the present invention are vertically arranged before side shaping. The shape of the workpiece is similar to a "Ji" shape, and there are flanges at the lower ends of the two side walls. Place the workpiece on the punch, the protrusion in the middle of the workpiece fits with the upper surface of the punch, and the lower flange fits with the surface of the workbench. The fixed pressing block descends, and the fixed pressing block first contacts the protruding part in the middle of the workpiece and presses the protruding part tightly against the upper surface of the punch, thereby realizing the fixing effect on the workpiece. The shaping blocks on both sides descend until they contact the side walls of the workpiece. While descending, the shaping blocks start to shape the side walls of the workpiece.

[0021] The shaping surface of the shaping block is parallel to the shaping surface of the punch. During the descent of the shaping block, the side surface of the workpiece is continuously squeezed so that the side wall of the workpiece abuts against the side surface of the punch, thereby realizing the side shaping of the workpiece.

[0022] Since the two side surfaces of the punch are provided with curved surfaces that are in conformity with the shape of the workpiece, when the shaping block moves into place, the side shaping of the workpiece can be realized. After shaping, the shape of the side wall of the workpiece is the same as the shape of the two side surfaces of the punch 1, that is, meeting the design requirements of the workpiece.

[0023] Since the shaping block needs to continuously approach the workpiece while descending to achieve the side shaping of the workpiece, the shaping block moves along an inclined line during the working process. Therefore, it cannot be directly driven by a press and requires auxiliary guiding equipment. To ensure that the movement trajectory of the shaping block meets the requirements of side shaping, a guiding groove matching the shaping block is provided on the guiding block. The shaping block descends along the guiding groove under the action of the pressing mechanism. During the descent of the lower shaping block, the purpose of gradually approaching the workpiece is achieved through the inclined guiding groove, enabling the shaping block to reliably extrude and shape the workpiece along a direction parallel to the side surface of the punch, thus reliably ensuring the side shaping quality of the workpiece.

[0024] Therefore, by using a single-power side shaping die for flanged workpieces, the shaping block moves up and down from top to bottom. Through the action of the guiding groove, the shaping block approaches the workpiece while descending, thus reliably avoiding the problem of interference between the shaping block and the horizontal flange, and achieving the side shaping effect of flanged workpieces.

[0025] In this embodiment, preferably, the single-power side shaping die for flanged workpieces further includes a second driving mechanism that can act on the shaping block.

[0026] The two sides of the shaping block 3 are simultaneously driven by the second driving mechanism, thereby achieving the effect of simultaneously performing side shaping on both sides of the workpiece.

[0027] In one embodiment, the upper end of the second driving mechanism can be set to be connected to the press, and the lower end is respectively connected to the shaping blocks on both sides in a contactable manner. When the workpiece needs to be shaped, the press acts and pushes the second driving mechanism to descend. During the descent of the second driving mechanism, the shaping blocks in contact with it on both sides are simultaneously pushed to descend.

[0028] The lower end of the second driving mechanism is set in an inverted U shape, and the two ends of the inverted U shape are respectively connected to the two shaping blocks in a contactable manner.

[0029] In another embodiment, two second driving mechanisms are provided. Both of the two second driving mechanisms are connected to the press. During the descent of the press, the two driving mechanisms are simultaneously pressed down, which can also achieve the purpose of simultaneously acting on the two shaping blocks 3.

[0030] Preferably, the surface of the shaping block in contact with the second driving mechanism is set to be a plane. Since the shaping block also needs to perform horizontal movement during the descent, relative movement will occur between the second driving mechanism and the upper surface of the shaping block, and the second driving mechanism will gradually move from the inside of the shaping block to the outside of the shaping block. By setting the upper surface of the shaping block to be a plane, the second driving mechanism can easily slide on the shaping block, and the lifting process of the shaping block will also be more stable.

[0049] 102 Workbench Detailed Implementation

[0050] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0051] In the present invention, unless otherwise specified, the directional terms included in terms such as "directly above, below, both sides, one side, inclined, parallel, lower end face, lower than" only represent the direction of the term in its normal use state, or the common name understood by those skilled in the art, and should not be regarded as a limitation of the term.

[0052] See Figure 1 The single-power side shaping die for a flanged workpiece includes a punch 1 fixedly arranged below, a fixed pressing block 2 located directly above the punch 1, lifting shaping blocks 3 respectively located on both sides of the fixed pressing block 2, and a fixedly arranged guiding block 4 cooperating with the shaping blocks 3. An inclined guiding groove 41 is arranged on the side of the guiding block 4 facing the shaping block 3, and the shaping block 3 slides along the guiding groove 41 to achieve lifting and lowering.

[0053] The two side surfaces of the punch 1 are arranged as curved surfaces that are similar in shape to the workpiece 10. The shaping surface of the shaping block 3 is parallel to the shaping surface of the punch 1, and the guiding groove 41 is parallel to the shaping surface of the shaping block 3.

[0054] By implementing the above technical solution, the side walls on both sides of the workpiece 10 are vertically arranged before side shaping. The shape of the workpiece 10 is similar to a "Ji" shape, and there are flanges at the lower ends of the two side walls. The workpiece 10 is placed on the punch 1, the protrusion in the middle of the workpiece 10 fits with the upper surface of the punch 10, and the lower flange fits with the surface of the workbench 102. The fixed pressing block 2 descends. The fixed pressing block 2 first contacts the protruding part in the middle of the workpiece 10 and presses the protruding part tightly against the upper surface of the punch 1, thereby realizing the fixing effect on the workpiece 10. The shaping blocks 3 on both sides descend until they contact the side walls of the workpiece 10. While descending, the shaping blocks 3 start to shape the side walls of the workpiece 10.

[0055] The shaping surface of the shaping block 3 is parallel to the shaping surface of the punch 1. During the descent of the shaping block 3, the side of the workpiece 10 is continuously squeezed so that the side wall of the workpiece 10 abuts against the side surface of the punch 10, thereby realizing the side shaping of the workpiece 10.

[0056] Since the two side surfaces of the punch 10 are arranged as curved surfaces that are similar in shape to the workpiece 10, when the shaping block 3 moves in place, the side shaping of the workpiece 10 can be achieved. After shaping, the shape of the side wall of the workpiece 10 is the same as the shape of the two side surfaces of the punch 1, that is, it meets the design requirements of the workpiece 10.

[0057] Since the shaping block 3 needs to continuously approach the workpiece 10 while descending to achieve side shaping of the workpiece 10, the shaping block 3 moves along an inclined line during operation and thus cannot be directly driven by the press 101 and requires an auxiliary guiding device. To ensure that the movement trajectory of the shaping block 3 meets the requirements of side shaping, a guiding groove 41 matching the shaping block 3 is provided on the guiding block 4. The shaping block 3 descends along the guiding groove 41 under the action of the press 101 structure. During the descent of the lower shaping block 3, the purpose of gradually approaching the workpiece 10 is achieved through the inclined guiding groove 41, enabling the shaping block 3 to reliably extrude and shape the workpiece 10 along a direction parallel to the side surface of the punch 1, thus reliably ensuring the side shaping quality of the workpiece 10.

[0058] Therefore, by using a single-power side shaping die for flanged workpieces, the shaping block 3 moves up and down from top to bottom. Through the action of the guiding groove 41, the shaping block approaches the workpiece 10 while descending, thus reliably avoiding the problem of interference between the shaping block and the horizontal flange, achieving the side shaping effect for flanged workpieces, and in this way, the shaping block 3 can easily achieve negative angle shaping of the workpiece 10.

[0059] In this embodiment, preferably, the single-power side shaping die for flanged workpieces further includes a second driving mechanism capable of acting on the shaping block 3.

[0060] The two sides of the shaping block 3 are simultaneously driven by the second driving mechanism to achieve the effect of simultaneously performing side shaping on both sides of the workpiece 10.

[0061] In one embodiment, the upper end of the second driving mechanism can be connected to the press 101, and the lower ends are respectively connected to the two sides of the shaping block 3 in a contactable manner. When the workpiece 10 needs to be shaped, the press 101 acts and pushes the second driving mechanism downward. During the downward movement of the second driving mechanism, the two sides of the shaping block 3 in contact with it are simultaneously pushed downward.

[0062] The lower end of the second driving mechanism is provided in an inverted U shape, and the two ends of the inverted U shape are respectively connected to the two shaping blocks 3 in a contactable manner.

[0063] In another embodiment, the second driving mechanism is provided with two, and both of the two second driving mechanisms are connected to the press 101. During the downward movement of the press 101, the two driving mechanisms are simultaneously pressed down, and the purpose of simultaneously acting on the two shaping blocks 3 can also be achieved.

[0064] Preferably, the surface of the shaping block 3 in contact with the second driving mechanism is set as a flat surface. Since the shaping block 3 also needs to perform a horizontal movement during the descending process, relative movement will occur between the second driving mechanism and the upper surface of the shaping block 3, and the second driving mechanism will gradually move from the inner side of the shaping block 3 to the outer side of the shaping block 3. By setting the upper surface of the shaping block 3 as a flat surface, the second driving mechanism can easily slide on the shaping block 3, and the lifting process of the shaping block 3 will also be more stable.

[0065] In this embodiment, preferably, the second driving mechanism includes a second driving member 61, a second pressure block 62, and a pressure plate 63 for connecting the second driving member 61 and the second pressure block 62. The second pressure block 62 and the second driving member 61 are respectively located on both sides of the pressure plate 63.

[0066] Two second pressure blocks 62 are provided, and the two second pressure blocks 62 are respectively arranged at both ends of the pressure plate 63. The second pressure block 62 is connected to the shaping block 3 in a contactable manner, and the second driving member 61 is connected to the press 101.

[0067] When the press 101 operates, it will push the second driving member 61 to descend. During the descending process of the second driving member 61, it drives the pressure plate 63 to descend, and the second pressure blocks 62 connected to both ends of the pressure plate 63 move downward simultaneously. During the descending process of the second pressure blocks 62, they push the shaping block 3 to descend, thereby achieving the shaping effect on the workpiece 10.

[0068] Preferably, two second driving members 61 are provided, and the two second driving members 61 are respectively located at both ends of the pressure plate 63. The press 101 drives the two second driving members 61 to descend simultaneously, making the force on the pressure plate 63 more stable and improving the stability of the shaping block 3 during the working process.

[0069] In this embodiment, preferably, the single-power-side shaping die for flanging workpieces further includes a first driving member 51 that can act on the fixed pressure block 2.

[0070] The fixed pressure block 2 needs to contact the workpiece 10 first. After the fixed pressure block 2 contacts and compresses the workpiece 10, the fixed pressure block 2 maintains its position and no longer moves downward. Then the shaping block 3 will contact the workpiece 10, and subsequently the shaping block 3 continues to descend until the side shaping work on the workpiece 10 is completed.

[0071] Therefore, the working strokes of the fixed pressure block 2 and the shaping block 3 are different and cannot move synchronously with the shaping block 3. The first driving member 51 is provided to drive the fixed pressure block 2.

[0072] In this embodiment, preferably, the first driving member 51 is fixedly connected to the pressure plate 63, the pressure plate 63 is slidably connected to the fixed pressing block 2 through the limiting rod 21, and an elastic compressible member 52 is disposed between the pressure plate 63 and the fixed pressing block 2.

[0073] One end of the limiting rod 21 is fixedly connected to the pressure plate 63, a limiter is provided at the other end, and the length of the limiting rod 21 remains unchanged. A connection hole is provided on the fixed pressing block 2, and the limiting rod 21 passes through the connection hole to connect the fixed pressing block 2 to the pressure plate 63. An elastic compressible member 52 is disposed between the pressure plate 63 and the fixed pressing block 2. In the initial state of the fixed pressing block 2, the elastic compressible member 52 presses the fixed pressing block 2 to the limiter end of the limiting rod 2. Subsequently, when the pressure plate 63 starts to descend and the fixed pressing block 2 starts to descend, when the fixed pressing block 2 contacts the workpiece 10, under the action of the punch 1, the fixed pressing block 2 cannot continue to descend, then the elastic compressible member 52 located between the pressure plate 63 and the fixed pressing block 2 is compressed, and the fixed pressing block 2 starts to move away from the limiter. Subsequently, the pressure plate 63 continues to descend, and the shaping block 3 starts to perform side shaping on the workpiece 10. During this process, the elastic compressible member 52 continues to be compressed until the shaping is completed.

[0074] After the shaping is completed, the pressure plate 63 starts to ascend, the shaping block 3 starts to move upward, and the elastic compressible member 52 starts to recover. Until the pressure plate 63 finishes ascending and the shaping block 3 leaves the workpiece 10, the elastic compressible member 52 returns to its initial state, and the single-power side shaping die for flanging workpieces completes one working cycle.

[0075] Preferably, the elastic compressible member 52 is set as a nitrogen spring. After using the nitrogen spring, the pressure received by the fixed pressing block 2 does not change with the deformation amount of the nitrogen spring. It can ensure the reliability of pressing the workpiece 10 by the fixed pressing block 2.

[0076] The upper end of the first driving member 51 is fixedly connected to the press 101, and the lower end is fixedly connected to the pressure plate 63. During the downward movement of the press 101, the first driving member 51 and the second driving member 61 drive the pressure plate 63 together, thereby achieving the purpose of side shaping the workpiece 10 with a single power.

[0077] Using the same press 101 and simultaneously driving the pressure plate 63 by the first driving member 51 and the two second driving members 61 can ensure that the pressure plate 63 is evenly stressed and the work is stable.

[0078] In this embodiment, preferably, the lower end surface of the fixed pressing block 2 is lower than the lower end surface of the second pressure block 62.

[0079] The lower end surface of the fixed pressing block 2 is set to be lower than the lower end surface of the second pressing block 62, which can ensure that in the working sequence of the single-power-side shaping die for flanged workpieces, the fixed pressing block 2 first contacts the workpiece 10, and reliable fixation of the workpiece 10 can be achieved before the side shaping starts.

[0080] In this implementation manner, preferably, the pressure plate 63 is provided with a through hole, and the elastically compressible member 52 is disposed in the through hole.

[0081] During the working process of the single-power-side shaping die for flanged workpieces, the position of the elastically compressible member 52 remains unchanged, and only elastic expansion and contraction occur.

[0082] In one implementation manner, through the connection action of the limiting rod 21 on the fixed pressing block 2 and in cooperation with the through hole on the pressure plate 63, the elastically compressible member 52 can be fixed between the fixed pressing block 2 and the pressure plate 63.

[0083] In one implementation manner, one end of the elastically compressible member 52 is fixedly connected to the pressure plate 63, and the other end is fixedly connected to the fixed pressing block 2. The through hole on the pressure plate 63 can provide an installation position for the elastically compressible member 52 and can also provide a working space for the elastic expansion and contraction process of the elastically compressible member 52.

[0084] When the press 101 descends, the pressure plate 63 drives the fixed pressing block 2 and the second pressing block 62 located below it to descend. Immediately afterwards, the fixed pressing block 2 contacts the workpiece 10 above the punch 1, and the fixed pressing block 2 cannot continue to descend. Subsequently, during the descent of the pressure plate 63, the elastically compressible member 52 is compressed until the shaping block 3 descends in place and the pressure plate 63 no longer continues to descend.

[0085] When the press 101 ascends, the pressure plate 63 ascends accordingly, the second pressing block 62 is lifted, the elastically compressible member 52 is released and starts to recover. As the pressure plate 63 continues to be lifted, the elastically compressible member 52 continuously recovers until it returns to the initial position, the fixed pressing block 2 contacts the stopper, and the fixed pressing block 2 ascends under the action of the limiting rod 21.

[0086] Therefore, the single-power-side shaping die for flanged workpieces can achieve the purpose of performing side shaping on the workpiece 10 using a single power.

[0087] Preferably, as Figure 7 shown, when performing side shaping on the workpiece 10, the press 101 can also directly press the pressure plate 63, and the side shaping effect of the workpiece 10 can also be achieved.

[0088] In this implementation manner, preferably, the single-power-side shaping die for flanged workpieces further includes a return spring 7 for jacking up the shaping block 3, and the return spring 7 is located below the shaping block 3.

[0089] The reset spring 7 is arranged below the shaping block 3. During the downward movement of the shaping block 3, the reset spring 7 is continuously compressed. When the press 101 rises, the pressure plate 63 drives the lower fixed pressing block 2 and the second pressure block 62 to rise together, while the shaping block 3 moves upward under the elastic force of the reset spring 7. At this time, the shaping block 3 still cooperates with the positioning block 4 and moves upward along the guiding groove 41.

[0090] In this embodiment, preferably, the height of the reset spring 7 is less than the height of the positioning block 4, and after the reset spring 7 is reset, the shaping block 3 will not come out of the guiding groove 41.

[0091] In this embodiment, preferably, a guiding protrusion 31 is arranged on the surface of the shaping block 3 facing the guiding groove 41, and a guiding groove matching with the guiding protrusion 31 is arranged in the guiding groove 41. Through the cooperation of the guiding protrusion 31 and the guiding groove, it can be reliably ensured that during the reciprocating movement of the shaping block 3, the relative position with the positioning block 4 is always kept unchanged, thereby ensuring the reliability of the side shaping of the shaping block 3.

[0092] Preferably, the guiding protrusions 31 are symmetrically arranged to keep the shaping block horizontal during the movement.

[0093] The present invention also provides a stamping method for a single-power side shaping die using a flanging workpiece, including:

[0094] Step 1: Place the workpiece 10 on the punch 1, and the fixed pressing block 2 presses down to press the workpiece 10 tightly on the punch 1;

[0095] Step 2: The shaping block 3 slides downward along the guiding groove 41 to shape the side wall of the workpiece 10;

[0096] Step 3: The shaping block 3 slides upward, and the fixed pressing block 2 slides upward;

[0097] Step 4: Take out the workpiece 10.

[0098] Through the implementation of the above technical solution, first, the flanging workpiece 10 with right-angled side walls is sleeved above the punch 1, and then the press 101 presses down, and the fixed pressing block 2 presses the workpiece 10 tightly on the punch 1. Subsequently, the shaping block 3 slides downward along the guiding groove 41, and after contacting the side wall of the workpiece 10, it starts to shape the side wall of the workpiece 10. As the shaping block 3 moves, the side wall of the workpiece 10 is extruded to the side of the punch 1, and finally, the side wall of the workpiece 10 forms an angle consistent with the punch 1.

[0099] Subsequently, both the shaping block 3 and the fixed pressing block 2 slide upward to release the workpiece 10. After the workpiece 10 is released, the workpiece 10 can be taken out.

[0100] In this embodiment, preferably, in step four, the workpiece 10 is taken out from the side surface of the punch 1.

[0101] When the side surface of the workpiece 10 is formed into a negative angle, the workpiece 10 cannot be taken out from above, but can only be taken out from the side surface of the punch 10.

[0102] The punch 1 can be set to have the kinetic energy of horizontal movement. In one embodiment, the punch 1 and the workpiece 10 are provided with a relatively fixed structure. After stamping is completed, the workpiece 10 can be transported out by the translation of the punch 1 to facilitate the operator to take out the workpiece. In another embodiment, the punch 1 can be set to translate, while the workpiece 10 is relatively fixed with the workbench 102. After the punch 1 translates, the automatic workpiece taking device can realize the grasping work of the workpiece 10.
