Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production equipment, in particular to a demoulding jacking structure and a stamping equipment. Background Art

[0002] During the vehicle body production process, stamping equipment is required to stamp metal sheets to form body sheet metal parts. Specifically, the stamping equipment includes a lower die base and an upper die base, and the lower die base is provided with a lifting mechanism that can be raised and lowered. During the production process, the robot transfers the metal sheet to the lower die base, and then the upper and lower die bases are combined to stamp the metal sheet into body sheet metal. After the body sheet metal is stamped and formed, the lifting mechanism lifts the body sheet metal and separates it from the lower die base. Finally, the body sheet metal is taken away by clamps and transferred to subsequent production stations.

[0003] As the degree of automation of automobile production lines increases, the production rhythm is also getting faster and faster. For example, the minimum production rhythm of multi-station (Transfor) production lines is about 15 SPM. Therefore, during the production process, when the metal sheet is placed on the lower die seat, or when the lifting mechanism lifts the body sheet metal, the parts may fluctuate relative to the lower die seat. The fluctuation of parts during the stamping process will lead to poor consistency in product size. In severe cases, the metal sheet will be out of position, causing the line to stop, and even damage to the mold tooling. After stamping, the fluctuation of parts will cause the clamp to be unable to clamp accurately, which may cause inaccurate positioning of the body sheet metal in subsequent stations, affecting the production rhythm.

[0030] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] like Figure 1 and Figure 2As shown, the embodiment of the demoulding lifting structure according to the present application includes a lifting head 10, a rod body 20 and a plurality of adsorption structures 30. The lifting head 10 has a first profile 11, and the lifting head 10 is suitable for matching with the part to be processed through the first profile 11. The rod body 20 is connected to the lifting head 10 and is suitable for being inserted into the mold base. The plurality of adsorption structures 30 are arranged on the first profile 11 of the lifting head 10.

[0035] By utilizing the technical solution of this embodiment, a plurality of adsorption structures 30 are provided on the first molding surface 11 of the lifting head 10. The adsorption structures 30 can adsorb the parts to be processed so that the parts to be processed can be firmly fixed on the lifting head 10. The plurality of adsorption structures 30 can provide a plurality of stable fixing points for the parts to be processed, thereby achieving a better fixing effect. In the above structure, when the parts to be processed are being stamped, the adsorption structures 30 of the lifting head 10 can fix the parts to be processed on the die base. After the parts to be processed are stamped, the lifting head 10 lifts the parts, and the adsorption structures 30 can prevent the fluctuation caused by the rising inertia. Therefore, the technical solution of this embodiment solves the defect that the parts in the stamping equipment in the prior art are prone to fluctuation relative to the lower die base, resulting in poor consistency in the size of the parts after stamping, which affects the subsequent positioning accuracy.

[0036] First of all, it should be noted that, for the sake of convenience, the demoulding and lifting structure is used in the field of automobile body sheet metal stamping as an example. However, those skilled in the art can understand that the demoulding and lifting structure in this embodiment can be applied in various stamping fields, and the following description cannot be understood as limiting the application scenarios of the demoulding and lifting structure of this application.

[0037] like Figure 1 and Figure 2 As shown, the lifting head 10 is a block-shaped structure, and a first mold surface 11 is arranged at the top thereof. The first mold surface 11 means that the first mold surface 11 squeezes the sheet material during the stamping process, so that the sheet material is pressed into a predetermined shape. The lifting head 10 cooperates with the part to be processed through the first mold surface. In this embodiment, the part to be processed refers to the metal sheet before stamping, and refers to the body sheet metal after stamping.

[0038] Furthermore, before and during the stamping of the metal sheet, the lifting head 10 supports it. After the metal sheet is stamped into a body sheet metal, the lifting head 10 lifts it and separates it from the die base.

[0039] like Figure 1 and Figure 2 As shown, the rod body 20 is a rod-shaped structure, and the rod body 20 is movably arranged on the mold base. The rod body 20 is arranged on the bottom end surface of the lifting head 10. The rod body 20 is used to penetrate the mold base to support and guide the lifting head 10, so that the lifting head 10 can move along a preset direction (that is, the axial direction of the rod body 20).

[0040] In this embodiment, the lifting head 10 and the rod body 20 are separate structures, which are connected by screws. A through hole is provided on the lifting head 10, and a threaded hole is provided on the end face of the rod body 20. The screw passes through the through hole and is tightened in the threaded hole, thereby fixing the lifting head 10 on the rod body 20.

[0041] In some embodiments not shown, the lifting head 10 and the rod body 20 may also be connected by welding or bonding, or the lifting head 10 and the rod body 20 may also be connected by integral molding.

[0042] like Figure 1 and Figure 2 As shown, a plurality of adsorption structures 30 are arranged on the first molding surface 11 of the jacking head 10. Since the first molding surface 11 cooperates with the part to be processed, the adsorption force generated by the adsorption structure 30 can directly act on the part to be processed, so that the part to be processed can be quickly and stably fixed on the jacking head 10.

[0043] When the parts to be processed are placed on the die base before stamping, the parts to be processed can be quickly fixed on the lifting head 10 by the adsorption structure 30, thereby preventing the parts to be processed from rising and falling relative to the die base, ensuring the dimensional consistency of the parts after stamping, and preventing the parts from leaving the processing position and causing the line to stop.

[0044] After the parts to be processed are stamped, the lifting head 10 needs to rise and push the body sheet metal out of the mold, that is, separate the body sheet metal from the mold base. During the rising process of the body sheet metal, the adsorption structure 30 can fix the body sheet metal on the lifting head 10 to prevent the body sheet metal from fluctuating due to the inertia generated by the rise, and ensure the accurate positioning of the subsequent grasping.

[0045] Preferably, the adsorption structure 30 mentioned above may be a magnetic adsorption structure or a vacuum adsorption structure.

[0046] In the technical solution of this embodiment, the adsorption structure 30 is a magnetic adsorption structure. Since the parts to be processed are made of metal (metal sheets, car body sheet metal), the magnetic force generated by the magnetic adsorption structure can adsorb the parts to be processed on the lifting head 10.

[0047] Optionally, the adsorption structure may be a permanent magnet, an electromagnet, a magnetic seat, etc., as long as it can apply magnetic force.

[0048] In some embodiments not shown, the adsorption structure 30 may also be a vacuum adsorption structure, which can also fix the workpiece to be processed on the lifting head 10 by applying negative pressure.

[0049] Optionally, the vacuum adsorption structure may include a suction cup, an adsorption hole, and the like.

[0050] like Figure 2 As shown, in the technical solution of this embodiment, the first mold surface 11 includes a top surface 111 and a side surface 112 , and both the top surface 111 and the side surface 112 are provided with adsorption structures 30 .

[0051] Specifically, the shape of the first profile 11 is designed according to the actual needs of the body sheet metal. In this embodiment, the first profile 11 is roughly stepped, and has multiple planes and vertical surfaces. The plane located on the uppermost side is the top surface 111 mentioned above, and the vertical surface is the side surface 112 mentioned above. By arranging the adsorption structure 30 on the top surface 111 and the side surface 112, it is possible to apply adsorption force to the part to be processed in two different directions (vertical direction and horizontal direction), so that the part to be processed is fixed more stably.

[0052] like Figure 2 As shown, in this embodiment, one adsorption structure 30 is disposed on the top surface 111 , and one adsorption structure 30 is disposed on the side surface 112 , that is, two adsorption structures 30 are disposed in total.

[0053] In some embodiments not shown, a plurality of adsorption structures 30 may be disposed on the top surface 111 , or a plurality of adsorption structures 30 may be disposed on the side surface 112 , so as to increase the adsorption force on the workpiece to be processed.

[0054] Optionally, the side surface 112 in this embodiment may be a vertical surface or an inclined surface (a straight surface or a curved surface).

[0055] like Figure 2 As shown, in the technical solution of this embodiment, the adsorption structure 30 includes a magnetic block, and an accommodating recess 12 is provided on the first mold surface 11 , and the magnetic block is arranged in the accommodating recess 12 .

[0056] Specifically, the magnetic block is configured as a circular columnar block, and correspondingly, the receiving recess 12 is circular, and the magnetic block is disposed in the receiving recess 12. In order to prevent the magnetic block from affecting the shape of the part after stamping, the magnetic block is configured not to protrude from the opening of the receiving recess 12, and preferably, the outer end of the magnetic block is slightly lower than the opening of the receiving recess 12. This configuration not only prevents the magnetic block from affecting the shape of the part, but also enables the magnetic block to be as close to the part as possible to maintain a greater adsorption force.

[0057] In some embodiments not shown, the magnetic block may also be configured in other shapes.

[0058] Preferably, the adsorption force of the magnetic block is in the range of 50 N to 60 N. If the adsorption force is too small, the purpose of adsorbing and stabilizing the parts cannot be achieved, but if the adsorption force is too large, the speed of the clamp grabbing and lifting the parts will be reduced, affecting the production cycle, and a large adsorption force will easily cause deformation of thin plate parts.

[0059] Optionally, in this embodiment, a threaded hole is provided on the bottom wall of the accommodating recess 12, and a connecting screw is provided in the middle of the circular magnetic block. The magnetic block is fixed by screwing the connecting screw into the threaded hole.

[0060] In some embodiments not shown, the magnetic block may also be fixed in the accommodating recess 12 by bonding, snapping, or the like.

[0061] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, a first limiting step 21 is provided on the side of the rod body 20, and the first limiting step 21 is suitable for limiting the position of the rod body 20 in the mold base. Specifically, the first limiting step 21 is mainly used to limit the upper limit position of the movement of the lifting head 10 (described in detail below).

[0062] from Figure 1 and Figure 2 It can be seen that the first limiting step 21 is formed by cutting downward a portion of the outer wall of the upper end surface of the rod body 20 (that is, the end facing the lifting head 10 ), so the first limiting step 21 is set toward the lifting head 10 .

[0063] In some embodiments not shown, a protrusion may be added to the outer wall of the rod body 20 to form the first limiting step 21 mentioned above.

[0064] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, a sensor 40 is provided on the side of the jacking head 10 , and the sensor 40 is suitable for detecting the relative position of the part to be processed and the jacking head 10 .

[0065] Specifically, the sensor 40 can detect the relative position between the part to be processed and the lifting head 10, so as to determine whether the lifting head 10 has adsorbed the part to be processed. The sensor 40 sends a detection signal to the control system, and the control system determines whether to perform a subsequent stamping operation.

[0066] Optionally, the sensor 40 may be a photoelectric switch, a proximity sensor, or the like.

[0067] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the sensor 40 is roughly cylindrical in structure, and is connected to the side of the lifting head 10 through a bracket. Figure 2 It can be seen that a mounting notch is provided at the top of the jacking head 10, and the mounting notch passes through the top and side of the jacking head 10, and forms a top opening and a side opening respectively. One end of the bracket extends into the mounting notch through the side opening and is fixed to the bottom wall of the mounting notch by screws, and the sensor 40 is connected to the other end of the bracket.

[0068] In order to prevent the sensor 40 from affecting the shape of the part after stamping, the sensor 40 is configured so that the end thereof protrudes from the top opening of the mounting notch. Preferably, and preferably, the outer end of the sensor 40 is slightly lower than the top opening of the mounting notch. Such a configuration not only prevents the sensor 40 from affecting the shape of the part, but also enables the sensor 40 to be as close to the part as possible, thereby ensuring a high detection accuracy.

[0069] like Figure 1 and Figure 2 As shown, in the technical solution of this embodiment, the rod body 20 is a sleeve structure, and an elastic reset member 50 is arranged inside the rod body 20.

[0070] Specifically, the lower end of the rod body 20 is open, the elastic reset member 50 is assembled in the rod body 20, and the lower end of the elastic reset member 50 protrudes from the lower end of the rod body 20. When the die is closed by stamping, the lifting head 10 is pressed down, so that the elastic reset member 50 is compressed. When the die is opened after stamping, the elastic reset member 50 releases the elastic force, so that the rod body 20 and the lifting head 10 rise together, lift the body sheet metal upward, and realize demolding.

[0071] Optionally, the elastic return member 50 is a spring.

[0072] like Figures 3 to 8 As shown, the present application also provides a stamping device. According to an embodiment of the stamping device of the present application, it includes a die base 100 and the above-mentioned demoulding lifting structure 200. Among them, the die base 100 has a second mold surface 101, and a mounting hole 102 is provided on the die base 100. The demoulding lifting structure 200 is movably arranged in the mounting hole 102. Furthermore, the demoulding lifting structure 200 has a retracted position and an extended position. When the demoulding lifting structure 200 is in the retracted position, the first mold surface 11 of the lifting head 10 is flush with the second mold surface 101. When the demoulding lifting structure 200 is in the extended position, the end of the lifting head 10 protrudes from the second mold surface 101.

[0073] like Figure 3 As shown, the die base 100 in this embodiment is a lower die base, so the demoulding lifting structure 200 is arranged on the lower die base. Those skilled in the art can understand that the stamping equipment also includes an upper die base (not shown in the figure), and the upper die base and the lower die base are closed and opened to stamp the metal sheet into the body sheet metal.

[0074] Furthermore, in this embodiment, two demoulding lifting structures 200 are provided on the mold base 100, respectively located on both sides of the second molding surface 101, so as to ensure stable lifting of the body sheet metal. Of course, those skilled in the art can adjust the specific number and arrangement position of the demoulding lifting structures 200 on the mold base 100 according to actual needs.

[0075] Furthermore, the rod body 20 is movably arranged in the mounting hole 102, so that the lifting head 10 can move in the vertical direction. The demoulding lifting structure 200 has a retracted position and an extended position. Figure 3 and Figure 4 As shown, when the demoulding lifting structure 200 is in the retracted position, the first mold surface 11 and the second mold surface 101 are flush, and the two together constitute the stamping surface. Figure 6 and 7 As shown, when the demoulding lifting structure 200 is in the extended position, the upper end of the lifting head 10 protrudes from the second molding surface 101, so that the stamped body sheet metal can be lifted and demoulded.

[0076] like Figure 5 and Figure 8 As shown, in the technical solution of this embodiment, a first limiting step 21 is provided on the side of the rod body 20, and a second limiting step 1021 is provided on the inner side wall of the mounting hole 102. The first limiting step 21 is located below the second limiting step 1021, and when the demoulding lifting structure 200 is in the extended position, the first limiting step 21 abuts against the second limiting step 1021.

[0077] Specifically, the second limiting step 1021 protrudes from the inner side wall of the mounting hole 102 and faces downward. The first limiting step 21 is located below the second limiting step 1021 and faces downward.

[0078] like Figure 5 As shown, when the stamping equipment is closing the mold, the upper mold base moves downward and drives the demoulding lifting structure 200 to move downward to the retracted position. During the downward movement of the demoulding lifting structure 200, the first limiting step 21 moves downward and away from the second limiting step 1021, and the elastic reset member 50 is compressed. When the demoulding lifting structure 200 moves to the point where the first molding surface 11 and the second molding surface 101 are flush, the demoulding lifting structure 200 moves to the lower limit position.

[0079] like Figure 8As shown, when the stamping equipment opens the mold after stamping, the upper mold seat moves upward, and the demoulding lifting structure 200 loses the pressure from above. Therefore, the elastic reset member 50 releases the elastic force and drives the demoulding lifting structure 200 to move upward. During the upward movement of the demoulding lifting structure 200, the first limiting step 21 gradually approaches the second limiting step 1021 until the first limiting step 21 and the second limiting step 1021 abut, so that the demoulding lifting structure 200 is in the upper limit position.

[0080] like Figure 5 and Figure 8 As shown, in the embodiment and technical solution, the side wall of the mounting hole 102 has a groove 1022, and the groove 1022 extends from the end surface of the mounting hole 102 toward the inner side of the mounting hole 102, and forms a mounting surface 1023. The stamping equipment also includes a limit block 300, and the limit block 300 is connected to the mounting surface 1023. The limit block 300 protrudes from the inner side wall of the mounting hole 102, and forms a second limit step 1021 on the surface facing the first limit step 21.

[0081] Specifically, a portion of the side wall of the mounting hole 102 is cut downward at the end surface of the mounting hole 102 to form a groove 1022. The bottom surface of the groove 1022 forms a mounting surface 1023, and the mounting surface 1023 is a horizontal surface. The limit block 300 is set on the mounting surface 1023, and the end of the limit block 300 protrudes from the inner side wall of the mounting hole 102. Figure 5 It can be seen that the portion of the limiting block 300 protruding from the inner wall of the mounting hole 102 and the surface facing downward form the second limiting step mentioned above.

[0082] like Figure 5 and Figure 8 As shown, in the technical solution of this embodiment, the limit block 300 is connected to the mounting surface 1023 through a threaded structure, and the jacking head 10 is provided with an avoidance hole 13, which corresponds to the threaded structure.

[0083] like Figure 5 As shown, a through hole is provided on the limit block 300, and a threaded hole is provided on the mounting surface 1023. The threaded connection structure includes a screw. After the screw passes through the through hole and the threaded hole, the limit block 300 is fastened to the mounting surface.

[0084] Further, from Figure 5 and Figure 8 It can be seen that it is difficult to operate the screw because the lifting head 10 covers the upper position of the slot 1022. In order to solve this problem, in this embodiment, a avoidance hole 13 is provided on the lifting head 10. Specifically, the avoidance hole 13 passes through the upper and lower surfaces of the lifting head 10, and the avoidance hole 13 is concentrically arranged with the above-mentioned through hole and threaded hole.

[0085] During installation, an external tool (electric screwdriver, etc.) can pass through the avoidance hole 13 to operate the screw, thereby facilitating the removal of the limit block 300 .

[0086] The following describes the installation and disassembly process of the demoulding lifting structure 200:

[0087] Installation: First, equip the elastic reset member 50 at the lower end of the rod body 20, and insert the rod body 20 into the mounting hole 102. Then press the rod body 20 downward until the first limiting step 21 is lower than the mounting surface 1023. Then, install the limiting block 300 on the mounting surface 1023 by screws, and the rod body 20 is limited in the mounting hole 102. Then, fix the lifting head 10 on the rod body 20 by screws to complete the assembly.

[0088] Disassembly: After the external tool passes through the avoidance hole 13, the screw on the limit block 300 is unscrewed. At this time, the lifting head 10 is directly lifted up to remove the demoulding lifting structure 200 and the limit block 300 together.

[0089] like Figures 3 to 8 As shown, in the technical solution of this embodiment, the mold base 100 includes a base 103 and an insert 104 arranged on the base 103, and the surface of the insert 104 forms a second molding surface 101. The mounting hole 102 is arranged on the base 103, and the insert 104 is provided with a receiving hole 105, the mounting hole 102 is located in the receiving hole 105, and the receiving hole 105 is suitable for receiving the lifting head 10.

[0090] Specifically, the type of the insert 104 on the base 103 can be changed according to the surface shape of the part to be stamped. When the demoulding lifting structure 200 is in the retracted position, the lifting head 10 is located in the receiving hole 105, and the first profile 11 of the lifting head 10 is flush with the second profile 101 of the insert 104. When the demoulding lifting structure 200 is in the extended position, the upper end of the lifting head 10 protrudes from the insert 104, thereby achieving the effect of lifting and demoulding the body sheet metal.
