Description

Technical Field

[0001] This invention relates to the field of molding equipment technology, specifically to an automatic material removal molding equipment and process for automotive side panels. Background Technology

[0002] The side panel of a car is an important component of the vehicle body, consisting of the A-pillar, B-pillar, C-pillar, and sill, providing structural support and safety protection. In the event of an accident, rollover or side impact can cause significant stress on the B-pillar, leading to deformation and breakage. If this results in the B-pillar being irreparable and requiring cutting, the mechanic will need to completely cut it off, replace it with a new one, and weld it to the main body of the side panel. Figure 8 As shown, the B-pillar of the side wall is welded to the side wall through the upper and lower connection points to complete the maintenance work.

[0003] Chinese patent CN215237231U discloses a molding die for a car B-pillar, including a lower mold and an upper mold. This molding die achieves the one-piece molding of the B-pillar through the setting of structures such as telescopic rods, connecting rods, fixed mold splitting, and sliding mold splitting. However, the welded side B-pillar is only connected by the welding point, which will affect the overall structural strength. In addition, during the welding process, manual labor or jigs are required to control the side B-pillar to align with the welding point, which is not conducive to the welding work of the welder. During the side B-pillar molding process, a small amount of waste will fall off the workpiece, mix with the material drawing oil and adhere to the mold, which can easily scratch the workpiece.

[0004] Based on this, the present invention designs an automatic material removal automotive side panel molding equipment and its process to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automatic material removal molding equipment and process for automotive side panels.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic desizing automotive side panel molding equipment includes a press body, a base on the lower side of the press body, and a pressure plate fixedly installed on the upper output end of the press body;

[0008] A fixed lower mold is fixedly installed on the upper end of the base, and a movable upper mold is fixedly installed on the lower end of the pressure plate. The fixed lower mold and the movable upper mold cooperate to press the sheet material into shape. A bending mechanism is provided on one side of the lower connection point between the fixed lower mold and the movable upper mold. An automatic oiling mechanism is provided inside the fixed lower mold. A synchronous cleaning mechanism is installed on the base. Two sets of synchronous cleaning mechanisms are provided and symmetrically distributed on the front and rear sides of the fixed lower mold.

[0009] The angle-folding mechanism includes a fixed base, a bottom sliding block, a side sliding block, and a top pressing block. The fixed base is fixedly installed on the base, and the bottom sliding block and the side sliding block are movably installed on the fixed base. The bottom sliding block and the side sliding block are slidably connected by a concave-convex structure, and the top pressing block is fixedly installed on the pressure plate.

[0010] Furthermore, the fixed base is provided with a movable groove, the inner wall of the movable groove and the side wall of the bottom sliding block are slidably connected, a nitrogen spring is provided in the movable groove, and the top of the nitrogen spring is fixedly connected to the bottom sliding block; a guide slope and a mold closing surface are provided on the left side of the fixed base, the mold closing surface is located at the lower end of the guide slope, and the side of the side sliding block away from the bottom sliding block is slidably connected to the guide slope.

[0011] Furthermore, a bending head is fixedly installed on the right side of the side sliding block, and a bending groove is opened on the left side of the top pressure block, with the bending head and the bending groove being inserted into each other.

[0012] Furthermore, the synchronous cleaning mechanism includes a swing arm, a magnetic block, a support, a fixing plate, a tension spring, and a vertical rod. The support and the fixing plate are fixedly installed on the base, with the fixing plate located on the right side of the support. The fixing plate is rotatably connected to the right side of the swing arm via a rotating shaft. A magnetic block is fixedly installed on the left end of the swing arm, and a tension spring is fixedly installed between the right end of the swing arm and the fixing plate. The vertical rod is fixedly connected to the pressure plate, and the right sidewall of the swing arm and the sidewall of the vertical rod are slidably connected.

[0013] Furthermore, the vertical rod is designed in the shape of an hourglass.

[0014] Furthermore, the automatic oiling mechanism includes an oil outlet component, an oil inlet chamber, an oil delivery chamber, an oil storage tank, and an air pump. Multiple sets of oil outlet components are evenly distributed along the side wall of the fixed lower mold. An oil storage tank is fixedly installed on the side wall of the base, and an air pump is fixedly installed at the lower end of the oil storage tank. An oil delivery chamber communicating with the oil storage tank is opened inside the base and the fixed lower mold. The oil delivery chamber is connected to the oil outlet component through multiple oil inlet chambers opened in the pressure plate.

[0015] Furthermore, the oil outlet assembly includes a groove, a slider, a return spring, and an oil outlet cavity. The lower mold is fixed with a groove, and the slider is slidably connected to the groove. The groove can completely accommodate the slider. The end of the slider away from the groove is set as an inclined surface. The return spring is fixedly installed in the groove and abuts against the slider. The slider is provided with an oil outlet cavity. The outlet of the oil outlet cavity is located at the inclined surface of the slider, and the inlet of the oil outlet cavity is located on the upper side of the slider. A trigger structure electrically connected to the air pump is also provided in the groove.

[0016] Furthermore, in its natural state, the slider extends out of the groove, and the inlet of the oil outlet chamber is misaligned with the inlet of the oil inlet chamber. When the slider is fully inserted into the groove, the inlet of the oil outlet chamber aligns with and connects with the inlet of the oil inlet chamber, and the triggering structure inside the groove is activated.

[0017] To better achieve the objectives of this invention, the present invention also provides a process for an automatic de-waxing automotive side panel molding equipment, comprising the following steps:

[0018] Step 1: The pressure plate drives the top pressure block to move vertically downward. When the top pressure block contacts the bottom sliding block, it drives the bottom sliding block to move vertically downward in the movable groove. The nitrogen spring buffers and dampens the shock. At the same time, the bottom sliding block drives the side sliding block to move vertically downward, and the guide slope pushes the side sliding block towards the bottom sliding block until the lower end face of the side sliding block is in contact with the mold closing surface. At this time, the bending head of the side sliding block is inserted into the bending groove of the top pressure block, and the sheet metal is bent out of the groove.

[0019] Step 2: When the fixed lower die and the movable upper die are closed, the movable upper die presses down to draw the sheet metal. The drawn sheet metal pushes the slider into the groove through the inclined surface of the slider. When the slider is completely pushed into the groove, the oil outlet chamber and the oil inlet chamber are connected. The slider triggers the trigger structure, and the air pump runs to force the oil in the oil storage tank into the oil delivery chamber. The oil in the oil delivery chamber flows into the oil outlet chamber through the oil inlet chamber and finally flows out from the outside of the slider onto the drawing surface of the sheet metal.

[0020] Step 3: The tension spring pulls the swing arm so that the right end of the swing arm is always in contact with the vertical rod. During the process of mold closing and mold opening of the fixed lower mold and the movable upper mold, the upper, middle and lower sides of the vertical rod slide against the swing arm in sequence. Thus, when the fixed lower mold and the movable upper mold are fully closed and fully reset, the swing arm rotates to the outside of the mold to avoid affecting the material loading and unloading and the mold closing operation. During the mold opening process, the swing arm rotates between the fixed lower mold and the movable upper mold to absorb and remove the metal debris attached to the lower side of the movable upper mold.

[0021] The present invention has the following technical effects:

[0022] 1. In this invention, the operator places the sheet metal on the fixed lower die. The pressing plate of the press body drives the movable upper die to move vertically downward. The fixed lower die and the movable upper die work together to press the sheet metal, automatically removing it by cutting along the edge, thus pressing the sheet metal into shape in one step. While pressing the side wall B-pillar, the top pressing block presses down on the bottom sliding block. The fixed seat and the side sliding block work together to drive the bottom sliding block to move towards the top pressing block, bending the excess part at the lower connection point of the sheet metal into a groove. Thus, when using this side wall B-pillar to repair the damaged side wall, the groove can be engaged with the side wall, which not only facilitates welding work for the welder but also increases the bonding area between the side wall B-pillar and the side wall, greatly increasing the strength of the side wall after repair.

[0023] 2. In this invention, the synchronous cleaning mechanism is synchronized with the opening and closing actions of the fixed lower die and the movable upper die. Each time the die is opened and closed, it extends between the fixed lower die and the movable upper die to clean the metal particles on the movable upper die. When the fixed lower die and the movable upper die are closed, the sheet metal is gradually drawn, triggering the automatic oiling mechanism to spray drawing oil on the drawing surface of the sheet metal, reducing the friction between the sheet metal and the die, and increasing the yield.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The present invention will be further described below with reference to embodiments.

[0037] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0038] Example 1

[0039] Please refer to the instruction manual appendix. Figure 1-3 An automatic material removal molding machine for automobile side panels includes a press body 100, a base 110 on the lower side of the press body 100, and a pressure plate 120 fixedly installed on the upper output end of the press body 100.

[0040] A fixed lower mold 130 is fixedly installed on the upper end of the base 110, and a movable upper mold 140 is fixedly installed on the lower end of the pressure plate 120. The fixed lower mold 130 and the movable upper mold 140 cooperate to press the sheet material into shape. A bending mechanism 200 is provided between the fixed lower mold 130 and the movable upper mold 140 on one side of the lower connection point 603. An automatic oiling mechanism 300 is provided inside the fixed lower mold 130. A synchronous cleaning mechanism 400 is installed on the base 110. Two sets of synchronous cleaning mechanisms 400 are provided and symmetrically distributed on the front and rear sides of the fixed lower mold 130.

[0041] The angle bending mechanism 200 includes a fixed base 210, a bottom sliding block 220, a side sliding block 230, and a top pressing block 240. The fixed base 210 is fixedly installed on the base 110. The bottom sliding block 220 and the side sliding block 230 are movably installed on the fixed base 210. The bottom sliding block 220 and the side sliding block 230 are slidably connected by a concave-convex structure. The top pressing block 240 is fixedly installed on the pressure plate 120.

[0042] In this invention, the operator places the sheet metal on the fixed lower die 130. The pressure plate 120 of the press body 100 drives the movable upper die 140 to move vertically downward. The fixed lower die 130 and the movable upper die 140 cooperate to press the sheet metal, automatically removing the sheet metal along the edge, thus pressing the sheet metal into shape in one step. The synchronous cleaning mechanism 400 is synchronized with the opening and closing actions of the fixed lower die 130 and the movable upper die 140. Each time the molds open and close, it extends between the fixed lower die 130 and the movable upper die 140 to clean the metal particles on the movable upper die 140. When the fixed lower die 130 and the movable upper die 140 close, the sheet metal is gradually stretched, triggering the automatic oiling mechanism 300 to apply oil to the sheet metal. Spraying drawing oil on the drawing surface reduces the friction between the sheet metal and the die, increasing the yield. While pressing the side wall B-pillar 601, the top pressing block 240 presses down the bottom sliding block 220. The fixed seat 210 and the side sliding block 230 work together to move the bottom sliding block 220 toward the top pressing block 240, bending the excess part at the lower connection point 603 of the sheet metal into a groove. Thus, when using the side wall B-pillar 601 to repair the damaged side wall 600, the groove can be engaged with the side wall 600, which not only facilitates welding work but also increases the bonding area between the side wall B-pillar 601 and the side wall 600, greatly increasing the strength of the repaired side wall 600.

[0043] Example 2

[0044] like Figure 3 As shown, in a preferred embodiment of the present invention, the fixed base 210 is provided with a movable groove 212, the inner wall of the movable groove 212 and the side wall of the bottom sliding block 220 are slidably connected, a nitrogen spring 250 is provided in the movable groove 212, and the top of the nitrogen spring 250 is fixedly connected to the bottom sliding block 220; a guide slope 211 and a mold closing surface 213 are provided on the left side of the fixed base 210, the mold closing surface 213 is located at the lower end of the guide slope 211, and the side of the side sliding block 230 away from the bottom sliding block 220 is slidably connected to the guide slope 211; a bending head 231 is fixedly installed on the right side of the side sliding block 230, and a bending groove 241 is provided on the left side of the top pressure block 240, the bending head 231 and the bending groove 241 are inserted into each other.

[0045] In this invention, the pressure plate 120 drives the top pressure block 240 to move vertically downward. When the top pressure block 240 contacts the bottom sliding block 220, it drives the bottom sliding block 220 to move vertically downward in the movable groove 212. The nitrogen spring 250 buffers and dampens the shock. At the same time, the bottom sliding block 220 drives the side sliding block 230 to move vertically downward, and the guide slope 211 pushes the side sliding block 230 towards the bottom sliding block 220 until the lower end face of the side sliding block 230 is in contact with the mold closing surface 213. At this time, the bending head 231 of the side sliding block 230 is inserted into the bending groove 241 of the top pressure block 240, and the sheet metal is bent out of the groove. The side wall B pillar 601 can be welded to the lower connection point 603 through the groove, which is convenient for the welder to operate.

[0046] Example 3

[0047] like Figure 4 and 7 As shown, in a preferred embodiment of the present invention, the synchronous cleaning mechanism 400 includes a swing arm 410, a magnetic block 420, a support 430, a fixing plate 440, a tension spring 450, and a vertical rod 460. The support 430 and the fixing plate 440 are fixedly installed on the base 110, and the fixing plate 440 is located on the right side of the support 430. The fixing plate 440 is rotatably connected to the right side of the swing arm 410 via a rotating shaft. The magnetic block 420 is fixedly installed on the left end of the swing arm 410, and the tension spring 450 is fixedly installed between the right end of the swing arm 410 and the fixing plate 440. The vertical rod 460 is fixedly connected to the pressure plate 120, and the right side wall of the swing arm 410 and the side wall of the vertical rod 460 are slidably connected.

[0048] The vertical rod 460 is designed to be nearly hourglass-shaped, with a large diameter on the top and bottom sides and a small diameter in the middle, and the transition between the different diameters of the vertical rod 460 is smooth.

[0049] In this invention, the tension spring 450 pulls the swing arm 410 so that the right end of the swing arm 410 is always in contact with the vertical rod 460. When the fixed lower mold 130 and the movable upper mold 140 are closed, the upper side of the vertical rod 460 pushes the swing arm 410 to rotate, and the swing arm 410 makes room so that the mold closing operation can proceed normally. After the fixed lower mold 130 and the movable upper mold 140 are separated, the middle part of the vertical rod 460 contacts the swing arm 410, and the swing arm 410 rotates to the position where the fixed lower mold 130 and the movable upper mold 140 are closed. Between 40, the magnetic block 420 adsorbs and removes the metal debris attached to the lower side of the movable upper mold 140. After the pressure plate 120 returns to the upper side of the press body 100, the lower side of the vertical rod 460 pushes open the swing rod 410, causing the swing rod 410 to rotate to both sides of the fixed lower mold 130, thus avoiding interference with the material handling. The vertical rod 460 and the swing rod 410 work together to achieve automatic cleaning of the metal debris attached to the mold, thereby preventing residual debris from scratching the finished product.

[0050] Example 4

[0051] like Figure 5 and 6 As shown, in a preferred embodiment of the present invention, the automatic oiling mechanism 300 includes an oil outlet component, an oil inlet chamber 350, an oil delivery chamber 360, an oil storage tank 370, and an air pump 380. The oil outlet component is provided in multiple sets and is evenly distributed along the side wall of the fixed lower mold 130. The oil storage tank 370 is fixedly installed on the side wall of the base 110, and the air pump 380 is fixedly installed at the lower end of the oil storage tank 370. The base 110 and the fixed lower mold 130 are provided with an oil delivery chamber 360 that communicates with the oil storage tank 370. The oil delivery chamber 360 is connected to the oil outlet component through multiple oil inlet chambers 350 opened in the pressure plate 120.

[0052] The oil outlet assembly includes a groove 310, a slider 320, a return spring 330, and an oil outlet cavity 340. The groove 310 is provided on the fixed lower mold 130. The slider 320 is slidably connected to the groove 310 and the groove 310 can completely accommodate the slider 320. The end of the slider 320 away from the groove 310 is set as an inclined surface. The return spring 330 is fixedly installed in the groove 310 and abuts against the slider 320. The oil outlet cavity 340 is provided on the slider 320. The outlet of the oil outlet cavity 340 is located at the inclined surface of the slider 320, and the inlet of the oil outlet cavity 340 is located on the upper side of the slider 320. A trigger structure electrically connected to the air pump 380 is also provided in the groove 310.

[0053] In its natural state, the slider 320 extends out of the groove 310. At this time, the inlet of the oil outlet chamber 340 is misaligned with the oil inlet chamber 350. When the slider 320 is fully inserted into the groove 310, the inlet of the oil outlet chamber 340 is aligned with the oil inlet chamber 350 and connected, and the triggering structure inside the groove 310 is activated.

[0054] In this invention, when the fixed lower mold 130 and the movable upper mold 140 are closed, the movable upper mold 140 presses down to draw the sheet metal. The drawn sheet metal pushes the slider 320 into the groove 310 through the inclined surface of the slider 320. After the slider 320 is fully pushed into the groove 310, the oil outlet chamber 340 is connected to the oil inlet chamber 350, and the slider 320 triggers the trigger structure. The air pump 380 operates to pressurize the oil in the oil storage tank 370 into the oil delivery chamber 360. The oil in the oil delivery chamber 360 flows into the oil outlet chamber 340 through the oil inlet chamber 350, and finally flows out from the outside of the slider 320 onto the drawing surface of the sheet metal, thus avoiding damage to the sheet metal.

[0055] Example 5

[0056] like Figure 1-8 As shown, in a preferred embodiment of the present invention, a process for an automatic de-waxing automotive side panel molding equipment is also provided, comprising the following steps:

[0057] Step 1: The pressure plate 120 drives the top pressure block 240 to move vertically downward. When the top pressure block 240 contacts the bottom sliding block 220, it drives the bottom sliding block 220 to move vertically downward in the movable groove 212. The nitrogen spring 250 buffers and dampens the shock. At the same time, the bottom sliding block 220 drives the side sliding block 230 to move vertically downward. The guide slope 211 pushes the side sliding block 230 towards the bottom sliding block 220 until the lower end face of the side sliding block 230 is in contact with the mold closing surface 213. At this time, the bending head 231 of the side sliding block 230 is inserted into the bending groove 241 of the top pressure block 240, and the sheet metal is bent out of the groove.

[0058] Step 2: When the fixed lower die 130 and the movable upper die 140 are closed, the movable upper die 140 presses down to draw the sheet metal. The drawn sheet metal pushes the slider 320 into the groove 310 through the inclined surface of the slider 320. When the slider 320 is completely pushed into the groove 310, the oil outlet cavity 340 is connected to the oil inlet cavity 350, and the slider 320 triggers the trigger structure. The air pump 380 runs to pressurize the oil in the oil storage tank 370 into the oil delivery cavity 360. The oil in the oil delivery cavity 360 flows into the oil outlet cavity 340 through the oil inlet cavity 350, and finally flows out from the outside of the slider 320 onto the drawing surface of the sheet metal.

[0059] Step 3: The tension spring 450 pulls the swing arm 410 so that the right end of the swing arm 410 is always in contact with the vertical rod 460. During the process of mold closing and mold opening of the fixed lower mold 130 and the movable upper mold 140, the upper, middle and lower sides of the vertical rod 460 slide with the swing arm 410 in sequence. Thus, when the fixed lower mold 130 and the movable upper mold 140 are fully closed and fully reset, the swing arm 410 rotates to the outside of the mold to avoid affecting the material loading and unloading and the mold closing operation. During the mold opening process, the swing arm 410 rotates between the fixed lower mold 130 and the movable upper mold 140 to absorb and remove the metal debris attached to the lower side of the movable upper mold 140.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.

5. The automatic de-waxing automotive side panel molding equipment according to claim 4, characterized in that, The oil outlet assembly includes a groove (310), a slider (320), a return spring (330), and an oil outlet cavity (340). The groove (310) is provided on the fixed lower mold (130). The slider (320) is slidably connected to the groove (310). The groove (310) can completely accommodate the slider (320). The end of the slider (320) away from the groove (310) is set as an inclined surface. The return spring (330) is fixedly installed in the groove (310) and abuts against the slider (320). The oil outlet cavity (340) is provided on the slider (320). The outlet of the oil outlet cavity (340) is located at the inclined surface of the slider (320), and the inlet of the oil outlet cavity (340) is located on the upper side of the slider (320). A trigger structure electrically connected to the air pump (380) is also provided in the groove (310).

6. The automatic de-waxing automotive side panel molding equipment according to claim 5, characterized in that, In its natural state, the slider (320) extends out of the groove (310), and the inlet of the oil outlet chamber (340) is misaligned with the oil inlet chamber (350). When the slider (320) is fully inserted into the groove (310), the inlet of the oil outlet chamber (340) is aligned with the oil inlet chamber (350) and connected, and the triggering structure inside the groove (310) is activated.

7. A process for an automatic de-waxing automotive side panel molding equipment as described in claim 6, characterized in that, Includes the following steps: Step 1: The pressure plate (120) drives the top pressure block (240) to move vertically downward. When the top pressure block (240) contacts the bottom sliding block (220), it drives the bottom sliding block (220) to move vertically downward in the movable groove (212). The nitrogen spring (250) buffers and reduces shock. At the same time, the bottom sliding block (220) drives the side sliding block (230) to move vertically downward. The guide slope (211) pushes the side sliding block (230) towards the bottom sliding block (220) until the lower end face of the side sliding block (230) is in contact with the mold closing surface (213). At this time, the bending head (231) of the side sliding block (230) is inserted into the bending groove (241) of the top pressure block (240), and the sheet metal is bent out of the groove. Step 2: When the fixed lower die (130) and the movable upper die (140) are closed, the movable upper die (140) presses down to draw the sheet metal. The drawn sheet metal pushes the slider (320) into the groove (310) through the inclined surface of the slider (320). When the slider (320) is completely pushed into the groove (310), the oil outlet cavity (340) is connected to the oil inlet cavity (350), and the slider (320) triggers the trigger structure. The air pump (380) runs to press the oil in the oil storage tank (370) into the oil delivery cavity (360). The oil in the oil delivery cavity (360) flows into the oil outlet cavity (340) through the oil inlet cavity (350) and finally flows out from the outside of the slider (320) onto the drawing surface of the sheet metal. Step 3: The tension spring (450) pulls the swing arm (410) so that the right end of the swing arm (410) is always in contact with the vertical rod (460). During the process of mold closing and mold opening of the fixed lower mold (130) and the movable upper mold (140), the upper, middle and lower sides of the vertical rod (460) slide with the swing arm (410) in sequence. Thus, when the fixed lower mold (130) and the movable upper mold (140) are fully closed and fully reset, the swing arm (410) rotates to the outside of the mold to avoid affecting the material loading and unloading and the mold closing operation. During the mold opening process, the swing arm (410) rotates between the fixed lower mold (130) and the movable upper mold (140) to absorb and remove the metal debris attached to the lower side of the movable upper mold (140).
