Description

Technical Field

[0001] This utility model relates to the field of stamping technology, and in particular to a stamping die for an engine hood lock reinforcement plate. Background Technology

[0002] The engine hood lock reinforcement plate is a key safety component in the engine hood structure. It is mainly used to improve the strength and rigidity of the latch area and ensure the reliable operation of the locking mechanism under collision or vibration conditions. It is usually made of high-strength steel plate by stamping and welding to the latch position of the inner panel of the engine hood to form a localized reinforcement structure. The manufacturing process includes stamping and flanging, welding of reinforcing ribs, etc.

[0003] A search of existing Chinese patent technology, "A stamping die for metal parts", with publication number "CN221246709U", reveals that the device uses a fixing rod to engage with a corresponding locking groove on its surface, which can also fix the angle of the rotating column, thus achieving the locking of the corresponding structure of the die and further improving the stability of the die after it is fixed. However, during the use of this device, since the sheet metal is continuously stamped, it is easy for the sheet metal to deviate during the conveying process, which affects the pass rate of the sheet metal stamping process. Utility Model Content

[0004] Therefore, it is necessary to provide a stamping die for an engine hood lock reinforcement plate to address the problem that continuous stamping of sheet metal can easily lead to deviation during sheet metal conveying, which affects the pass rate of sheet metal stamping.

[0005] A stamping die for an engine hood lock reinforcement plate includes: a mounting base, on the upper end of which a stamping die base is mounted; and an anti-deviation mechanism disposed on one side of the stamping die base and mounted on the upper end of the mounting base. The anti-deviation mechanism includes two fixed seats mounted on the upper end of the mounting base, each fixed seat having a control component connected to its surface, and two abutting components connected to the surface of the control component, the abutting components being disposed between the two fixed seats.

[0006] In one embodiment, the control component includes a sector plate fixedly connected to the fixed seat away from the surface of the stamping die seat. A rotating head is rotatably connected to the inner wall of the fixed seat. One end of the rotating head is fixedly connected to a connecting seat. Two crossbars are fixedly connected to the inner wall of the connecting seat. The crossbars are disposed between the two fixed seats, and the ends of the crossbars extend to the other side of the adjacent fixed seat.

[0007] In one embodiment, the control assembly includes two bearings fixedly connected to the surface of the crossbar, with an outer sleeve fixedly connected to the outer edge of the bearings. The outer sleeve is fitted over the outside of the crossbar and is located between two connecting seats.

[0008] In one embodiment, an arc-shaped hole is provided on one side of the sector plate, the longitudinal section of the arc-shaped hole is arc-shaped, and the surface of one of the crossbars is slidably connected to the inner wall of the arc-shaped hole.

[0009] In one embodiment, a plurality of positioning holes are provided on one side of the sector plate, and a positioning bolt is inserted into the inner wall of one of the positioning holes.

[0010] In one embodiment, the connecting seat has a threaded hole on the side near the adjacent fixing seat, and the surface of the positioning bolt is threaded to the inner wall of the threaded hole.

[0011] In one embodiment, a plurality of hard rubber rings are fixedly connected to the surface of the outer sleeve, and a soft rubber grid is provided between adjacent hard rubber rings, the soft rubber grid being fixedly connected to the surface of the outer sleeve.

[0012] In one embodiment, the inner wall of the outer sleeve is fixedly connected with a plurality of support plates, which are located between two bearings.

[0013] Beneficial effects

[0014] 1. The above-mentioned engine hood lock reinforcing plate stamping die, when one of the crossbars moves in an arc along the arc hole, causes the connecting seat to drive the threaded hole to swing synchronously. The hexagonal nut is connected to the end of one of the crossbars. The friction force limits the crossbar from easily shifting. In addition, the positioning bolt extends through the positioning hole into the threaded hole to position the connecting seat. The distance between the two crossbars provides an auxiliary positioning effect for stamping plates of different thicknesses, reducing the vibration and shift of the plate during continuous stamping and ensuring the pass rate of plate stamping.

[0015] 2. An external sleeve is fitted onto the surface of the crossbar. The crescent-shaped support plate provides good support. The soft rubber grid deforms when it comes into contact with the sheet metal, forming a good clamping and positioning for the stamping sheet metal. Multiple hard rubber rings can reduce the offset of the sheet metal and ensure that the sheet metal is not easily offset during the stamping process. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model 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 this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention relates to a stamping die for an engine hood lock reinforcement plate.

[0026] In one embodiment, a stamping die for an engine hood lock reinforcement plate includes: a mounting base 1, on the upper end of which a stamping die base 2 is mounted; and an anti-deviation mechanism 3, which is disposed on one side of the stamping die base 2 and mounted on the upper end of the mounting base 1. The anti-deviation mechanism 3 includes two fixed seats 33 mounted on the upper end of the mounting base 1. An adjustment component 31 is connected to the surface of each fixed seat 33, and two abutment components 32 are connected to the surface of the adjustment component 31, with the abutment components 32 disposed between the two fixed seats 33.

[0027] It should be noted that the engine hood lock reinforcement plate is installed in the latch area of ​​the inner panel of the engine hood. It is usually welded to the corresponding structure of the inner panel to form a local reinforcement structure. The latch fixing plate and the reinforcement plate work together to ensure that the latch can open smoothly after a collision, while also meeting the static load requirements. During welding, it is necessary to ensure that the plane of the latch is perpendicular to the center line of the latch to prevent loosening due to long-term vibration.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the control component 31 includes a sector plate 311 fixedly connected to the surface of the fixed seat 33 away from the stamping die seat 2. A rotating head 312 is rotatably connected to the inner wall of the fixed seat 33. A connecting seat 313 is fixedly connected to one end of the rotating head 312. Two crossbars 314 are fixedly connected to the inner wall of the connecting seat 313. The crossbars 314 are disposed between the two fixed seats 33. The ends of the crossbars 314 extend to the other side of the adjacent fixed seat 33. An arc-shaped hole 315 is opened on one side of the sector plate 311. The longitudinal section of the arc-shaped hole 315 is arc-shaped. The surface of one of the crossbars 314 is slidably connected to the inner wall of the arc-shaped hole 315. A plurality of positioning holes 316 are opened on one side of the sector plate 311. A positioning bolt 318 is inserted into the inner wall of one of the positioning holes 316. A threaded hole 317 is opened on the side of the connecting seat 313 near the adjacent fixed seat 33. The surface of the positioning bolt 318 is threadedly connected to the inner wall of the threaded hole 317.

[0029] In this embodiment, the device positions another crossbar 314 through the connecting seat 313 and the rotating head 312. When one of the crossbars 314 moves in an arc along the arc hole 315, the connecting seat 313 causes the threaded hole 317 to swing synchronously. At this time, a hexagonal nut can be connected to the end of one of the crossbars 314. When the hexagonal nut is tightly pressed against the side of the fan-shaped plate 311, the friction force limits the crossbar 314 from easily shifting. The connecting seat 313 can be positioned by the positioning bolt 318 passing through the positioning hole 316 and extending into the threaded hole 317. The distance between the two crossbars 314 can be used to assist in positioning stamping plates of different thicknesses, reducing the vibration and shifting of the plate during continuous stamping.

[0030] like Figure 2 , Figure 4 and Figure 5As shown, the control assembly 31 includes two bearings 324 fixedly connected to the surface of the crossbar 314. An outer sleeve 321 is fixedly connected to the outer edge of the bearings 324. The outer sleeve 321 is sleeved on the outside of the crossbar 314 and is located between two connecting seats 313. A plurality of hard rubber rings 322 are fixedly connected to the surface of the outer sleeve 321. A soft rubber grid 323 is provided between adjacent hard rubber rings 322. The soft rubber grid 323 is fixedly connected to the surface of the outer sleeve 321. A plurality of support plates 325 are fixedly connected to the inner wall of the outer sleeve 321 and are located between the two bearings 324.

[0031] In this embodiment, the device is fitted onto the surface of the crossbar 314 through an outer sleeve 321. The support plate 325 is crescent-shaped, which allows the interior of the outer sleeve 321 to form good support. The soft rubber grid 323 is made of soft rubber, which can deform to form a good clamping effect on the stamping plate when in contact with the plate. Multiple hard rubber rings 322 can reduce the plate displacement and ensure that the plate is not easily displaced during the stamping process.

[0032] Working principle: The connecting seat 313 and the rotating head 312 cooperate to position another crossbar 314. When one crossbar 314 moves along the arc-shaped hole 315, the connecting seat 313 drives the threaded hole 317 to swing synchronously. The hexagonal nut is connected to the end of one crossbar 314. When the hexagonal nut is tightly pressed against the side of the fan-shaped plate 311, the friction limits the crossbar 314 from easily shifting. The positioning bolt 318 passes through the positioning hole 316 and extends into the threaded hole 317 to position the connecting seat 313. The distance between the two crossbars 314 positions stamping plates of different thicknesses. The outer sleeve 321 is fitted on the surface of the crossbar 314. The support plate 325 is crescent-shaped, and the outer sleeve 321 provides good support. The soft rubber grid 323 is made of soft rubber. When it comes into contact with the plate, the soft rubber grid 323 deforms to clamp the stamping plate. Multiple hard rubber rings 322 reduce the plate shift.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
