[0002] Automotive body panels are an important component of the exterior of a car body, used to protect the internal structure and ensure passenger safety. Stamping is a common forming process in automobile manufacturing, using molds to shape sheet metal into the desired form, such as automotive body panels.

[0003] Currently, common automotive panel stamping devices lack pre-positioning and guiding functions for the upper and lower dies. After prolonged use, the piston rod may slightly deviate, leading to inaccurate alignment of the upper and lower dies and affecting the quality of the stamped panel. Furthermore, existing devices typically use hydraulic rods to push a push plate upwards, ejecting the finished panel from the lower die. However, the push plate is prone to wear after prolonged use, and disassembly and replacement are inconvenient, impacting maintenance efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a stable automobile panel stamping device, which aims to improve the accuracy of upper and lower die closing and improve the quality of stamped panel products.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable automobile panel stamping device, comprising a housing, a protective door hinged to the front end of the housing, a fixed seat fixed at the lower end of the housing, a lower die fixed at the upper end of the fixed seat, a hydraulic rod installed inside the fixed seat at a position corresponding to the lower die, a movable plate provided at the output end of the hydraulic rod, connecting columns fixed on both sides at the upper end of the movable plate, a push plate provided inside the lower die at the upper end of the connecting columns, a cylinder installed at the upper end of the housing at a position corresponding to the lower die, an upper die provided at the output end of the cylinder, the push plate and the connecting columns connected by a connecting component, and guide components provided at both ends of the upper die; The guide assembly includes a folding plate. Folding plates are fixed on both sides of the upper end of the upper mold. A positioning post is fixed on the lower end of the folding plate. An arc-shaped protrusion is fixed on the lower end of the positioning post. Positioning seats are fixed on both sides of the upper end of the fixing seat at positions corresponding to the positioning post. A positioning groove is opened in the positioning seat at a position corresponding to the positioning post. A flared opening is fixed on the upper end of the positioning seat at a position corresponding to the positioning groove.

[0006] Preferably, the guide assembly further includes an arc-shaped rod and a crossbar, with the arc-shaped rod fixed at both ends between the folding plate and the upper mold, and the crossbar fixed at both ends between the positioning seat and the outer shell.

[0007] Preferably, after the positioning post enters the positioning groove, the side of the positioning post fits tightly against the inner wall of the positioning groove, and a conical groove is opened inside the flared opening.

[0008] Preferably, the depth of the positioning groove is greater than the height of the positioning post, and the positioning seat and the fixed seat, as well as the positioning post and the folding plate, are fixed by welding.

[0009] Preferably, the connecting assembly includes a plug plate, with plug plates fixed on both sides of the lower end of the push plate, and a slot corresponding to the plug plate opened at the upper end of the connecting column.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please see Figure 1-4 The present invention provides the following technical solution: a stable automobile panel stamping device, including a housing 1, a protective door 6 hinged to the front end of the housing 1, a fixed seat 3 fixed to the lower end of the housing 1, a lower die 4 fixed to the upper end of the fixed seat 3, a hydraulic rod 5 installed inside the fixed seat 3 at a position corresponding to the lower die 4, a movable plate 12 provided at the output end of the hydraulic rod 5, connecting columns 11 fixed on both sides of the upper end of the movable plate 12, a push plate 7 provided inside the lower die 4 at the upper end of the connecting column 11, a cylinder 8 installed at the upper end of the housing 1 at a position corresponding to the lower die 4, an upper die 10 provided at the output end of the cylinder 8, the push plate 7 and the connecting column 11 are connected by a connecting component 9, and guide components 2 are provided at both ends of the upper die 10; The guide assembly 2 includes a folding plate 21. The upper mold 10 has two folding plates 21 fixed on both sides. The lower end of the folding plate 21 is fixed with a positioning post 23. The lower end of the positioning post 23 is fixed with an arc-shaped protrusion 26. The upper ends of the fixed seat 3 have two positioning seats 22 fixed at positions corresponding to the positioning post 23. The positioning seat 22 has a positioning groove 24 at a position corresponding to the positioning post 23. The upper end of the positioning seat 22 has a flared opening 25 at a position corresponding to the positioning groove 24.

[0016] Specifically, the guide assembly 2 also includes an arc-shaped rod 27 and a crossbar 28. The arc-shaped rod 27 is fixed at both ends between the folding plate 21 and the upper mold 10, and the crossbar 28 is fixed at both ends between the positioning seat 22 and the outer shell 1. By adopting the above technical solution, the firmness between the folding plate 21 and the upper mold 10 is improved by fixing the arc-shaped rod 27 between the folding plate 21 and the upper mold 10, and the stability of the positioning seat 22 is improved by fixing the crossbar 28 between the positioning seat 22 and the outer shell 1.

[0017] Specifically, after the positioning post 23 enters the positioning groove 24, the side of the positioning post 23 fits tightly against the inner wall of the positioning groove 24. The flared opening 25 has a conical groove inside. By adopting the above technical solution, after the positioning post 23 enters the positioning groove 24, the side of the positioning post 23 fits more tightly against the inner wall of the positioning groove 24. The conical groove inside the flared opening 25 facilitates the entry of the positioning post 23 into the flared opening 25.

[0018] Specifically, the depth of the positioning groove 24 is greater than the height of the positioning post 23. The positioning seat 22 and the fixed seat 3, as well as the positioning post 23 and the folding plate 21, are fixed by welding. By adopting the above technical solution, the positioning post 23 is prevented from affecting the stamping operation. The welding fixation makes the positioning seat 22 and the fixed seat 3, as well as the positioning post 23 and the folding plate 21, more secure.

[0019] In this embodiment, the blank to be stamped is placed in the lower die 4, the protective door 6 is closed, the cylinder 8 is turned on to push the upper die 10 downward to cooperate with the lower die 4 to perform stamping work on the blank. After the stamping work is completed, the hydraulic rod 5 is turned on to push the moving plate 12 and the connecting column 11 upward. The push plate 7 at the upper end of the connecting column 11 can push the stamped workpiece out of the lower die 4.

[0020] When the upper die 10 moves downward, the positioning pins 23 at the lower ends of the upper side folding plates 21 at both ends of the upper die 10 enter the flared opening 25. Then, the positioning pins 23 enter the positioning grooves 24 of the positioning seat 22 through the arc-shaped protrusion 26, thereby playing a pre-positioning and guiding role in the mold closing of the upper die 10 and the lower die 4. This avoids the slight wobbling of the piston rod after long-term use of the cylinder 8, which would cause the upper die 10 and the lower die 4 to have misalignment, affecting the quality of the stamped part of the panel.

[0021] The firmness between the folding plate 21 and the upper mold 10 is improved by fixing the arc-shaped rod 27 between the folding plate 21 and the upper mold 10, and the stability of the positioning seat 22 is improved by fixing the crossbar 28 between the positioning seat 22 and the outer shell 1.

[0022] Example 2: The difference between this embodiment and embodiment 1 is that: the connecting component 9 includes a insert plate 91, the push plate 7 has insert plates 91 fixed on both sides of its lower end, the connecting post 11 has a slot 92 corresponding to the insert plate 91 on its upper end, the insert plate 91 and the connecting post 11 are connected by an internal hex bolt 93, one end of the insert plate 91 has a fixing hole 94 corresponding to the internal hex bolt 93, and one end of the connecting post 11 has a groove 95 corresponding to the internal hex bolt 93. By adopting the above technical solution, the hydraulic rod 5 pushes the push plate 7 during disassembly and assembly. The moving plate 12 and the connecting column 11 are moved upward to a suitable height. Then, the insert plates 91 on both sides of the lower end of the push plate 7 are inserted into the slots 92 at the upper end of the connecting column 11. Then, the hexagonal socket bolts 93 are inserted into the connecting column 11 and screwed into the fixing holes 94 at one end of the insert plates 91 to achieve the effect of limiting and fixing the insert plates 91 and the push plate 7. At the same time, the end of the hexagonal socket bolts 93 enters the groove 95 to set the connecting component 9, which facilitates the disassembly and replacement of the push plate 7 and avoids the subsequent material ejection effect due to the wear of the push plate 7 after long-term use.

[0023] Specifically, after the hexagon socket bolt 93 is screwed into the fixing hole 94, the end of the hexagon socket bolt 93 enters the groove 95. The connecting post 11 has a through hole corresponding to the hexagon socket bolt 93. By adopting the above technical solution, the protrusion of the end of the hexagon socket bolt 93 is avoided from affecting the sliding of the connecting post 11. The hexagon socket bolt 93 can be inserted into the fixing hole 94 at one end of the connecting post 11 and screwed into the insert plate 91.

[0024] In this embodiment, when the push plate 7 is disassembled and assembled, the hydraulic rod 5 pushes the moving plate 12 and the connecting column 11 upward to a suitable height. Then, the insert plates 91 on both sides of the lower end of the push plate 7 are inserted into the slots 92 at the upper end of the connecting column 11. Then, the hexagonal bolts 93 are inserted into the connecting column 11 and screwed into the fixing holes 94 at one end of the insert plates 91 to achieve the effect of limiting and fixing the insert plates 91 and the push plate 7. At the same time, the end of the hexagonal bolts 93 enters the groove 95 to set the connecting component 9, which facilitates the disassembly and replacement of the push plate 7 and avoids the impact of wear on the push plate 7 due to long-term use on the subsequent material ejection effect.

[0025] The working principle and usage process of this utility model are as follows: First, install the device in a suitable position, put the blank to be stamped into the lower mold 4, close the protective door 6, open the cylinder 8 to push the upper mold 10 downward to cooperate with the lower mold 4 to stamp the blank. After the stamping work is completed, open the hydraulic rod 5 to push the moving plate 12 and the connecting column 11 upward. The push plate 7 at the upper end of the connecting column 11 can push the stamped workpiece out of the lower mold 4.

[0026] When the upper die 10 moves downward, the positioning pins 23 at the lower ends of the upper side folding plates 21 at both ends of the upper die 10 enter the flared opening 25. Then, the positioning pins 23 enter the positioning grooves 24 of the positioning seat 22 through the arc-shaped protrusion 26, thereby playing a pre-positioning and guiding role in the mold closing of the upper die 10 and the lower die 4. This avoids the slight wobbling of the piston rod after long-term use of the cylinder 8, which would cause the upper die 10 and the lower die 4 to have misalignment, affecting the quality of the stamped part of the panel.

[0027] The firmness between the folding plate 21 and the upper mold 10 is improved by fixing the arc-shaped rod 27 between the folding plate 21 and the upper mold 10, and the stability of the positioning seat 22 is improved by fixing the crossbar 28 between the positioning seat 22 and the outer shell 1.

[0028] When the push plate 7 is disassembled and assembled, the hydraulic rod 5 pushes the moving plate 12 and the connecting column 11 upward to a suitable height. Then, the insert plates 91 on both sides of the lower end of the push plate 7 are inserted into the slots 92 at the upper end of the connecting column 11. Then, the hexagonal bolts 93 are inserted into the connecting column 11 and screwed into the fixing holes 94 at one end of the insert plates 91 to achieve the effect of limiting and fixing the insert plates 91 and the push plate 7. At the same time, the end of the hexagonal bolts 93 enters the groove 95 to set the connecting component 9, which facilitates the disassembly and replacement of the push plate 7 and avoids the impact of wear on the push plate 7 due to long-term use on the subsequent material ejection effect.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
