[0002] The truck carriage panel stamping die is widely used in automobile manufacturing, logistics transportation and other industries, and is used for producing large panel parts such as side plates, bottom plates and top plates of the truck carriage. The stamping process is to apply pressure to the panel through the die to make it plastically deform or separate, so as to obtain the required shape and size. The truck carriage panel is usually large and complex in shape, so the requirements for the die are high. The stamping die cuts the flat panel through the cooperation of the upper knife block and the lower knife block, so as to obtain the panel with the required shape. Since the cutting area is completely located on the discharge side of the die, the die will have a lateral force, and the phenomenon of biting blade will occur. In order to eliminate the phenomenon of biting blade, a balance assembly is usually installed between the upper die holder and the lower die holder. Since the existing balance assembly and the die holder (including the upper die holder and the lower die holder) are integrally cast, the casting difficulty and processing difficulty of the die holder are increased. SUMMARY

DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model more clear and obvious, the utility model will be further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model.

[0023] Please see Figures 1 to 3 , now a kind of truck carriage body panel stamping die provided by the utility model will be described. The kind of truck carriage body panel stamping die, including: upper die holder 1, lower die holder 2, stripper plate 101, upper knife block 102, lower knife block 201 and balance assembly, it is characterized in that, balance assembly includes balance block 103, upper wear plate 104 and lower wear plate 202, balance block 103 can be detachably installed on upper die holder 1 and located in the side of upper knife block 102 away from lower knife block 201, upper wear plate 104 is fixedly installed on the side of balance block 103 away from upper knife block 102, lower wear plate 202 can be detachably installed on lower die holder 2 and correspond to upper wear plate 104.

[0024] The truck compartment plate stamping die provided by the embodiment balances the components, including the balancing block 103, the upper wear plate 104 and the lower wear plate 202. The balancing block 103 is detachably installed on the upper die seat 1 and located on the side of the upper die block 102 away from the lower die block 201. The upper wear plate 104 is fixedly installed on the side of the balancing block 103 away from the upper die block 102. The lower wear plate 202 is detachably installed on the lower die seat 2 and corresponds to the upper wear plate 104. In the die closing process, the upper wear plate 104 and the lower wear plate 202 are frictionally matched with each other, so as to offset the lateral force generated in the die cutting process, and thus eliminate the phenomenon of biting blade. Since the balancing block 103, the upper wear plate 104 and the upper die seat 1 are in a split structure, and the lower wear plate 202 and the lower die seat 2 are in a split structure, the balancing block 103, the upper wear plate 104 and the lower wear plate 202 do not need to be integrally cast with the die seat, so as to reduce the casting difficulty and processing difficulty of the die seat.

[0025] In some embodiments, referring to Figures 1 to 3 , the upper wear plate 104 is rectangular, and the lower wear plate 202 is U-shaped. In the embodiment, the upper wear plate 104 is rectangular, and the lower wear plate 202 is U-shaped, so that the upper wear plate 104 is slidably matched with the three faces of the inner cavity of the lower wear plate 202, and plays a guiding role in the upper die seat 1 and the lower die seat 2 while offsetting the lateral force of the die. Graphite dots are arranged on the sliding matching faces between the upper wear plate 104 and the lower wear plate 202. In the stamping process, the graphite dots can release graphite particles to reduce the friction between the upper wear plate 104 and the lower wear plate 202 and reduce wear. Graphite has certain heat conductivity, which can help heat dissipation and prevent the die from overheating. By reducing the friction and wear, the graphite dots can effectively prolong the service life of the die.

[0026] In some embodiments, referring to Figure 1 , the number of the lower wear plates 202 is two and symmetrically arranged. In the embodiment, the lower wear plate 202 corresponds to the upper wear plate 104. The number of the lower wear plate 202 and the upper wear plate 104 is two. The two lower wear plates 202 are symmetrically arranged at the discharging end of the lower die seat 2, so as to ensure the force balance between the lower die seat 2 and the upper die seat 1.

[0027] In some embodiments, referring to Figure 3The balancing block 103 is attached to the upper blade block 102. In this embodiment, a groove for installing the upper blade block 102 is formed on the upper die holder 1, and the balancing block 103 is also located in the groove. The outer contour of the balancing block 103 and the upper blade block 102 is matched with the inner contour of the groove, so that the groove plays a positioning role for the balancing block 103 and the upper blade block 102. Since the balancing block 103 is attached to the upper blade block 102, all the blanking forces borne by the upper blade block 102 can be directly offset by the upper wear plate 104 on the balancing block 103.

[0028] In some embodiments, the material of the balancing block 103 is Q235A, and the materials of the upper wear plate 104 and the lower wear plate 202 are T8. In this embodiment, the balancing block 103 serves as a base for supporting the upper wear plate 104, and the strength and toughness of Q235A can fully meet the application scenario. Since the upper wear plate 104 and the lower wear plate 202 need to be rubbed, T8 material with better wear resistance is selected.

[0029] In some embodiments, referring to Figure 5 , the lower wear plate 202 is connected with the lower die holder 2 by screws, and long circular holes 203 for installing the screws are formed on the lower wear plate 202, and the length direction of the long circular holes 203 is parallel to the feeding direction of the plate. In this embodiment, the length direction of the lower wear plate 202 is perpendicular to the feeding direction of the plate, and the long circular holes 203 are located at both ends of the length direction of the lower wear plate 202. The design of the long circular holes 203 allows the front and rear of the lower wear plate 202 to be adjusted, so that the lower wear plate 202 and the upper wear plate 104 can maintain a proper gap.

[0030] In some embodiments, referring to Figure 3 and Figure 4 , the discharging end of the lower die holder 2 is fixedly installed with a positioning base 204, and a positioning block 205 is fixedly installed on the side wall of the positioning base 204, and the positioning block 205 is used for positioning the front end of the plate. In this embodiment, the length direction of the positioning base 204 is perpendicular to the feeding direction of the plate. The positioning base 204 is fixedly connected with the lower die holder 2 by screws. The positioning block 205 is fixedly installed on the side wall of the positioning base 204 by screws, and the positioning block 205 is used for positioning the front end of the plate. The contour size of the positioning block 205 is smaller than the contour size of the positioning base 204. Since the positioning block 205 and the positioning base 204 are a split structure and have a smaller size, only the positioning block 205 needs to be repaired and replaced in the actual production process, which greatly reduces the maintenance cost. Since the positioning base 204 and the positioning block 205 are located below the upper blade block 102 and the balancing block 103, a giving slot is formed on the upper blade block 102 and the balancing block 103 for avoiding the positioning base 204 and the positioning block 205.

[0031] In some embodiments, referring to Figure 4 A gasket 206 is installed between the positioning block 205 and the positioning base 204.

[0032] In some embodiments, referring to Figure 2 and Figure 3 A material receiving plate 207 is installed on the lower die seat 2, and a return spring 208 is installed at the bottom of the material receiving plate 207. The material receiving plate 207 is located directly below the upper cutter block 102. In this embodiment, the material receiving plate 207 supports the plate material, and the material receiving plate 207 and the lower cutter block 201 support the plate material at the same time, thereby avoiding the bending deformation of the plate material on the lower die seat 2. The return spring 208 is a compression spring. When the upper cutter block 102 moves downward to punch the plate material, the material receiving plate 207 moves downward under the action of the lower cutter block 201, and the return spring 208 is compressed and deformed. When the punching is completed, the return spring 208 exerts an upward force on the material receiving plate 207, thereby resetting the material receiving plate 207.

[0033] In some embodiments, referring to Figure 1 and Figure 2 A side positioning plate 209 is also installed on the lower die seat 2, and the side positioning plate 209 is used to position the left and right sides of the plate material. In this embodiment, the side positioning plate 209 is fixed on the lower die seat 2 by screws, and the side positioning plate 209 is located at the feeding end of the lower die seat 2. The side positioning plate 209 positions the left and right sides of the plate material. The side positioning plate 209 cooperates with the positioning block 205 to ensure the position accuracy of the plate material during the punching process.

[0034] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
