In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0047] like Figures 1 to 4 and Figure 6As shown, a vehicle side panel blanking die comprises a first die 11 and a second die 12, the first die 11 and the second die 12 can move toward each other to shear the sheet material between the first die 11 and the second die 12, the first die 11 and the second die 12 both comprise a positioning base plate 2, a connecting member 3 and an insert 4, a plurality of positioning portions 21 are provided on the positioning base plate 2, the insert 4 is fixed to the positioning portion 21 by the connecting member 3, at least part of the connecting member 3 can be replaced on the plurality of positioning portions 21, so that the vehicle side panel blanking die can be applicable to the blanking processing of various types of side panels.

[0048] The first mold 11 and the second mold 12 both include the insert 4. The first mold 11 and the second mold 12 move toward each other and can shear the sheet material between the first mold 11 and the second mold 12 so that the blanked sheet material meets the size and model of the vehicle side panel to be processed. The positioning substrate 2 is provided with a plurality of positioning parts 21. The insert 4 is fixed to the positioning parts 21 through the connector 3. At least part of the connector 3 can be replaced on the plurality of positioning parts 21. When the size and model of the vehicle side panel to be processed are changed, the insert 4 is replaced at the fixed position of the positioning part 21 so that the shear line of the sheet material by the insert 4 meets the size requirements of the vehicle side panel to be processed, so that the vehicle side panel blanking mold is universal. The universality of the vehicle side panel blanking mold changes the mold production from personalized and customized single-piece production to universal mass production, which is conducive to improving the mold processing quality and efficiency. By adopting the vehicle side panel blanking die, the blanking processing of side panels of various sizes and models can be realized by designing a vehicle side panel production line, which can reduce the number of molds required, reduce the area of ​​the factory occupied by the production line, and reduce the mold investment cost.

[0049] It should be noted that the vehicle side panel blanking die is used for shearing and blanking the sheet material. The punching insert can also be detachably arranged on the positioning base plate 2 to improve the versatility of the punching die, and the utility model does not limit this.

[0050] In one embodiment, Figure 4 and Figure 5As shown, when processing a blanking die for a vehicle side panel of a new model and size, the connecting piece 3 is made corresponding to the blanking shear line of the vehicle side panel, and the insert 4 is fixed to the positioning portion 21 through the connecting piece 3. The universal insert 4 can be processed in a standardized process to improve the manufacturing accuracy of the insert 4. When the insert 4 is assembled on the positioning base plate 2, the insert 4 is adjusted less or even not adjusted, which can reduce the difference of the insert 4, reduce the complexity of the configuration during the assembly process, improve the standardization of the blanking die for the vehicle side panel, reduce the procurement cost, and improve the quality of the die.

[0051] At least one set of inserts is provided in a blanking area of ​​the sheet material, and one set of inserts includes one insert 4 staggered on each of the first mold 11 and the second mold 12. The inserts 4 of the first mold 11 and the second mold 12 stagger to shear the sheet material to achieve blanking of the sheet material. Multiple sets of inserts may be provided in a blanking area of ​​the sheet material, and there are insert seams between the multiple sets of inserts. The insert seams on the first mold 11 and the insert seams on the second mold 12 are staggered, so as to reduce burrs and other processing defects generated on the blanking line during the blanking operation of the sheet material.

[0052] In another embodiment, the insert 4, the connector 3 and the positioning substrate 2 are made of different materials. The insert 4, the connector 3 and the positioning substrate 2 are detachably connected, and can be processed separately using different materials without affecting the strength of the mold. For example, the insert 4 is made of SDK11 material, and the connector 3 and the positioning substrate 2 are made of FC30 material, which reduces the production cost of the mold and improves the convenience of repairing and replacing the mold parts when they are damaged.

[0053] As a preferred embodiment of the present invention, Figure 4 and Figure 6 As shown, the positioning portion 21 is provided with a positioning hole 211, and the connector 3 is provided with a positioning column 31. The positioning hole 211 and the positioning column 31 are plugged and matched so that the connector 3 can be detachably fixed to the positioning substrate 2. When assembling the connector 3, the positioning column 31 is preferably inserted into the positioning hole 211. The positioning column 31 cooperates with the positioning hole 211 to determine the assembly position of the connector 3, thereby improving the accuracy of the assembly and positioning of the connector 3. In addition, the positioning column 31 is plugged and matched with the positioning hole 211 to achieve the fixation of the connector 3 on the positioning substrate 2.

[0054] In another embodiment, if Figure 6As shown, one of the positioning portion 21 and the connecting member 3 is provided with a positioning groove, and the other is provided with a matching member that is snap-fitted with the positioning groove. The matching member can be snapped into the positioning groove to fix the connecting member 3 to the positioning portion 21.

[0055] Preferably, Figure 4 As shown, one of the connector 3 and the insert 4 is provided with a fixing protrusion 32, and the other is provided with a fixing groove 41 matched with the fixing protrusion 32 to position the insert 4 and the connector 3. When the insert 4 is assembled to the connector 3, the fixing protrusion 32 is preferably matched with the fixing groove 41 to determine the fixed position of the insert 4 on the connector 3. This improves the positioning accuracy of the insert 4 and improves the accuracy of shearing and blanking of the vehicle side panel blanking die.

[0056] In one embodiment, the fixing protrusion 32 is a structure made of polyurethane material. When the first mold 11 and the second mold 12 are relatively extruding the sheet material to shear and blank, the fixing protrusion 32 is in a compressed state. The fixing protrusion 32 clamps the sheet material under the action of elastic force, which facilitates the insert 4 to shear and blank the sheet material. After the shearing and blanking is completed, the first mold 11 and the second mold 12 are relatively separated, and the fixing protrusion 32 pops up, driving the sheet material away from the positioning base plate 2, so as to facilitate the sheet material to be taken out from the vehicle side panel blanking mold.

[0057] like Figure 4 and Figure 5 As shown, the connecting member 3 is provided with a fixing hole 33, the insert 4 is provided with a matching hole 42, and the vehicle side panel blanking die further includes a fixing member 5, and the fixing member 5 cooperates with the fixing hole 33 and the matching hole 42 to fix the insert 4 to the connecting member 3. The fixing member 5 cooperates with the fixing hole 33 and the matching hole 42 to fix the insert 4 to the connecting member 3, thereby further improving the stability of the fixing of the insert 4, reducing the vibration of the insert 4 when the vehicle side panel blanking die is sheared and blanked, and improving the stability of shearing and blanking.

[0058] The insert 4 is fixed to the positioning base plate 2 via the connecting member 3 , and the fixing method is relatively simple, which simplifies the assembly steps, reduces the assembly difficulty, and improves the versatility of the vehicle side panel blanking die.

[0059] As a preferred embodiment of the present invention, Figure 2As shown, the positioning substrate 2 includes a fixed area and a replacement area, and the connecting member 3 includes a first connecting portion 341 arranged in the fixed area and a second connecting portion 342 arranged in the replacement area, and the second connecting portion 342 is detachably connected to the positioning substrate 2. In the blanking processing of the side panels of vehicles of different models in series, there are generally common blanking and trimming areas and special blanking and trimming areas. The common blanking and trimming area is a fixed area, and the special blanking and trimming area is a replacement area. The second connecting portion 342 located in the replacement area is detachably connected to the positioning substrate 2. When performing the replacement processing of the vehicle side panels, it is only necessary to replace the second connecting portion 342 on the positioning substrate 2 to realize the universality of the mold, reduce the number of mold parts that need to be replaced, improve the universality of the mold, and reduce the difficulty and complexity of the part replacement operation.

[0060] In one embodiment, the utility model is applicable to the blanking processing of single-row side panels and half-row side panels of light commercial vehicles. When performing the universal setting of the blanking die for the vehicle side panels, the following steps are adopted:

[0061] S1: placing the blanking models of the single-row side panel and the row of half-side panel in the same model space, and aligning the front ends of the single-row side panel and the row of half-side panel;

[0062] S2: Analyze the blanking and trimming areas of the single-row side panels and the half-row side panels to obtain a common blanking and trimming area and a dedicated blanking and trimming area;

[0063] S3: a first connection portion 341 is provided in the common blanking and trimming area, and a second connection portion 342 is provided in the dedicated blanking and trimming area.

[0064] When performing the blanking process of the single-row side panel and the half-row side panel, the second connection portion 342 only needs to be replaced to realize the universal use of the vehicle side panel blanking die. The number of parts to be replaced in the vehicle side panel blanking die is reduced, the difficulty and complexity of the replacement operation are reduced, and the universality of the vehicle side panel blanking die is further improved.

[0065] In a preferred embodiment of the present invention, Figure 1 , Figure 3As shown, the first mold 11 includes a plurality of stoppers 6 disposed on the positioning substrate 2, and the plurality of stoppers 6 are arranged to form a stopper area 61 for accommodating the sheet material, and at least part of the stoppers 6 are detachably connected to the positioning substrate 2. The sheet material is placed in the stopper area 61 formed by the plurality of stoppers 6, and the stoppers 6 exert a stopper effect on the sheet material, thereby determining the placement position of the sheet material in the vehicle side panel blanking mold, and the fixed position of the insert 4 on the positioning substrate 2 is determined, thereby determining the shearing and blanking position of the insert 4 on the sheet material, thereby improving the accuracy of sheet material blanking processing.

[0066] In the conventional blanking die for the side panel of a vehicle, a limiting hole is punched on the sheet material, and a limiting column is arranged on the positioning substrate 2, and the sheet material is limited by the limiting column passing through the limiting hole. In the present utility model, the sheet material is placed in the limiting space, and the limiting member 6 is located at the edge of the limiting space and is misaligned with the sheet material, which reduces the processing steps of opening the limiting hole on the sheet material and simplifies the process flow of sheet material blanking.

[0067] At least part of the limiting member 6 is detachably connected to the positioning substrate 2. When processing vehicle side panels of different sizes, the limiting member 6 is replaced to make the limiting area 61 adapt to the size of the sheet material, further improving the versatility of the vehicle side panel blanking die. Vehicle side panel sheets of different sizes and models are overlapped at one end, and at least one common limiting member 6 is set at the overlapping end. When switching the size and model of the vehicle side panel, the common limiting member 6 does not need to be replaced, and only the dedicated limiting member 6 needs to be replaced to achieve the versatility of the vehicle side panel blanking die. Specifically, the limiting member 6 is provided with a pin 641, and the limiting member 6 is positioned by the pin 641. The limiting member 6 is also provided with a screw hole, and the limiting member 6 is fixed to the positioning substrate 2 by the screw 642 cooperating with the screw hole.

[0068] Preferably, Figure 7 and Figure 8 As shown, a plurality of the limiting members 6 are arranged to form a limiting area 61 for accommodating a sheet material, and the limiting member 6 has a limiting section 61 and an avoidance section 62 extending upward, and at least the avoidance section 62 has an avoidance slope 63 inclined in a direction away from the sheet material. The avoidance slope 63 avoids the sheet material, which is convenient for placing the sheet material in the limiting area 61 and reducing the attempt to position the sheet material. The avoidance slope 63 can guide the sheet material, adjust the placement position of the sheet material, and make it easier to place the sheet material in the limiting area 61. After the sheet material is placed in the limiting area 61, the limiting section 61 limits the sheet material, reduces the displacement and shaking of the sheet material during the blanking process, and thus improves the accuracy of blanking.

[0069] As a preferred embodiment of the present invention, Figure 3 and Fig. 9 As shown, a plurality of support members 7 are arranged on the positioning substrate 2, and the support members 7 are used to clamp the support plate from both sides of the plate, and the support members 7 are staggered with the insert 4. The support members 7 are staggered with the insert 4 to prevent the insert 4 from interfering with the support members 7 during shearing and blanking, which is convenient for the structural layout design of the vehicle side panel blanking die. The support members 7 clamp the support plate to reduce the warping deformation of the plate caused by the shear force of the insert 4, which is convenient for transportation and stamping and other processing operations in the subsequent assembly line processing of the vehicle side panel. It can also reduce the uneven changes in performance parameters such as sheet material stretching, reduce the occurrence of problems such as thinning of the thickness of some areas of the sheet material during the stamping process, and even cracks, improve the roughness of the surface of the vehicle side panel, and reduce the air resistance flowing through the surface of the vehicle side panel.

[0070] Preferably, Fig. 9 As shown, at least part of the support member 7 is connected to a driving member 71, which is disposed between the support member 7 and the positioning substrate 2 and can drive the support member 7 to move up and down relative to the positioning substrate 2. After the sheet material is sheared and blanked, the first mold 11 and the second mold 12 are relatively separated, and the driving member 71 drives the support member 7 to move up and down relative to the positioning substrate 2, so that the sheet material supported by the support member 7 is relatively separated from the positioning substrate 2, and the sheet material is released from the limiting area 61, so that the sheet material is further transported to the rear for processing.

[0071] The present application does not limit the specific form of the driving member 71, and any one of the following embodiments may be used or the following embodiments may be used in combination.

[0072] In one embodiment, the driving member 71 is an elastic member. After the sheet material is sheared and blanked, the first mold 11 and the second mold 12 are relatively separated, and the elastic member, under the action of elastic force, lifts the sheet material through the support member 7. The lifting height of the sheet material is at least greater than the vertical extension length of the limiter 6, thereby avoiding the restriction of the limiter 6 on the sheet material, and facilitating the transportation of the blanked sheet material to the rear of the assembly line.

[0073] In another embodiment, if Fig. 9As shown, the driving member 71 is a jack, which can directly push the sheet material to move relative to the positioning base plate 2, or push the sheet material to move relative to the positioning base plate 2 through the support member 7. After the sheet material is sheared and blanked, the first mold 11 and the second mold 12 are relatively far apart, and the jack can lift the sheet material so that the sheet material is away from the positioning base plate 2, so as to facilitate the sheet material to be transported to the rear of the assembly line.

[0074] As a preferred embodiment of the present invention, Figures 1 to 3 As shown, the first mold 11 and the second mold 12 both have a processing area and a guide area for processing sheet materials. The processing area and the guide area are arranged in a staggered manner. The first mold 11 is provided with a guide portion 81 in the guide area, and the second mold 12 is provided with a matching portion 82 that matches the guide portion 81 in the guide area. The guide portion 81 and the matching portion 82 cooperate to guide the relative movement of the first mold 11 and the second mold 12. The first mold 11 and the second mold 12 process the sheet materials located in the processing area. The processing area and the guide area are arranged in a staggered manner to avoid interference with the processing of the sheet materials by the setting of the guide portion 81 and the matching portion 82, which is convenient for the industrial design of the vehicle side panel. The guide portion 81 and the matching portion 82 cooperate to guide the relative movement of the first mold 11 and the second mold 12, reduce the shaking generated by the first mold 11 and the second mold 12 during the relative movement, and make the insert 4 more accurate and stable in shearing and blanking the sheet materials.

[0075] Specifically, Figures 1 to 3 As shown, the guide part 81 is arranged at the front and rear ends of the first mold 11, and the guide part 81 is a plurality of guide posts protruding from the first mold 11. The matching part 82 is arranged at the front and rear ends of the second mold 12, and the matching part 82 is a guide cavity recessed on the second mold 12. During the process of shearing and blanking of sheet metal, the first mold 11 and the second mold 12 move relative to each other to gradually approach each other, and the guide posts are inserted into the guide cavities. The guide posts and the guide cavities cooperate with each other, which reduces the relative shaking between the first mold 11 and the second mold 12 in the horizontal direction, improves the accuracy of shearing and blanking, reduces the relative displacement between the inserts 4, and reduces the processing problems such as burrs on the blanking trimming line of the sheet metal.
