Description

Technical Field

[0001] This utility model relates to the field of automotive hot stamping, specifically to a fixing device for hot stamping air intake grilles. Background Technology

[0002] Hot stamping of the air intake grille involves using a heated hot stamping head (heating plate) to bring the upper mold (silicone mold), hot stamping film, and air intake grille parts into close contact. Pressure is applied at a high temperature of 190-200 degrees Celsius, causing the adhesive layer, metal layer (such as aluminum or chromium), and protective layer of the hot stamping film to be transferred onto a specific surface of the air intake grille, creating a decorative effect.

[0003] During the hot stamping process, the air intake grille needs to be fixed to prevent it from shifting. The existing method is to fix the air intake grille with a clamp or a robotic arm before hot stamping. However, pressure needs to be applied to the air intake grille during hot stamping, so the clamp may cause the air intake grille to crack or break when it is clamped. Therefore, a fixing device is needed to replace the clamp in fixing the air intake grille during the hot stamping process. Utility Model Content

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A fixing device for hot stamping air intake grilles includes a fixed base, two fixing rods, and a bidirectional cylinder. The fixed base has a cavity, and the bidirectional cylinder is fixedly installed in the middle of the cavity. The fixed base has an opening that communicates with the cavity. The two fixing rods are respectively installed on both sides of the bidirectional cylinder. The bottom of the cavity has two limiting grooves, which are symmetrically arranged on both sides of the bidirectional cylinder. The bottoms of the two fixing rods are slidably connected to the two limiting grooves. The fixed base has a grille placement platform, and the grille placement platform has a fixing rod slot in the middle position. The top of the fixing rod passes through the fixing rod slot.

[0006] Preferably, the top of the grille placement platform has an arc-shaped structure that is low on both sides and high in the middle.

[0007] Preferably, the top outer periphery of the fixing rod is provided with an anti-slip sleeve.

[0008] Preferably, a rubber anti-collision pad is provided above the grille placement platform.

[0009] Preferably, the fixing rod slot is provided with two fixing rod collars, the inner wall of the fixing rod slot is provided with sliding grooves on both sides, the outer periphery of the fixing rod collar is provided with sliders, the two sliders are slidably connected to the sliding grooves on both sides respectively, and the two fixing rods pass through the two fixing rod collars respectively.

[0010] Preferably, a return spring is provided on one side of the fixing rod collar, and one end of the return spring is connected to the inner wall of the fixing rod slot.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model sets up two fixed rods, and controls the left and right movement of the two fixed rods by a two-way cylinder. By inserting the fixed rods into the gap of the air intake grille, and then moving the fixed rods, the air intake grille can be clamped or opened and fixed. Compared with traditional clamping, it can avoid the problem of damage to the air intake grille caused by excessive clamping force.

[0013] 2. By setting an anti-slip sleeve on the outer periphery of the top of the fixing rod and a rubber anti-collision pad on the grille placement platform, the air intake grille can not only be anti-slip when it is placed, but also avoid direct contact between the air intake grille and the fixing rod or grille placement platform, thus preventing damage to the air intake grille due to collision.

[0014] 3. By setting a fixing rod collar in the fixing rod slot, the fixing rod can be fitted with the fixing rod, and the fixing rod collar will also move along the sliding groove. This can prevent the fixing rod from shaking while moving under the action of the bidirectional cylinder, thus avoiding friction with the air intake grille and causing wear on the paint surface of the air intake grille.

[0024] Example 1

[0025] Reference Figure 1-2 A fixing device for hot stamping air intake grilles includes a fixed base 1, two fixing rods 2, and a bidirectional cylinder 3. The fixed base 1 has a cavity 1-1. The bidirectional cylinder 3 is fixedly installed at the bottom of the cavity 1-1, and the distance between the two sides of the bidirectional cylinder 3 and the two sides of the cavity 1-1 is the same. An opening 4 is provided above the cavity 1-1. The opening 4 is an oblong hole structure, and the center point of the opening 4 is aligned with the center point of the bidirectional cylinder 3. Two limiting grooves 5 are provided at the bottom of the cavity 1-1, and the two limiting grooves 5 are respectively located on both sides of the bidirectional cylinder 3. The two fixing rods 2 are respectively located in the two limiting grooves 5. The bidirectional cylinder 3 can simultaneously push or pull the two fixing rods 2 to move in opposite directions. A grille placement platform 6 is provided on the fixed base 1. The top of the grille placement platform 6 is an arc-shaped structure with low sides and high middle. A fixing rod slot 6-1 is provided in the middle position of the grille placement platform 6. The length of the fixing slot 6-1 is the same as the length of the opening 4. The top of the fixing rod 2 passes through the fixing rod slot 6-1.

[0026] In actual operation, the staff places the air intake grille on the grille placement platform 6, aligns the gap on the air intake grille with the fixing rod 2, and then controls the movement of the two fixing rods 2 by controlling the bidirectional cylinder 3, so that the fixing rods 2 clamp or support the air intake grille. This method can replace the traditional clamping method and can effectively reduce the problem of damage to the air intake grille by the clamp.

[0027] Example 2

[0028] Reference Figure 3 The difference between this embodiment and embodiment one is that an anti-slip sleeve 7 is provided on the outer periphery of the top of the fixing rod 2. The anti-slip sleeve 7 is made of cotton or rubber, which has a large friction with the ABS material commonly used in the air intake grille, preventing slippage during clamping. In addition, the texture is relatively soft, so the friction between the two will not damage the air intake grille.

[0029] Example 3

[0030] Reference Figure 4 The difference between this embodiment and embodiment one is that a rubber anti-collision pad 8 is provided above the grille placement platform 6. By using the rubber anti-collision pad 8, the air intake grille can be prevented from directly contacting the metal grille placement platform 6, thus avoiding the problem of deformation or damage to the air intake grille due to pressure or friction during the hot stamping process.

[0031] Example 4

[0032] Reference Figure 5 Two fixing rod collars 9 are provided in the fixing rod slot 6-1. Slide grooves 6-2 are provided on both sides of the inner wall of the fixing rod slot 6-1. Slider 10 is provided on the outer periphery of the fixing rod collar 9. The two sliders 10 are slidably connected to the slide grooves 6-2 on both sides respectively. The two fixing rods 2 pass through the two fixing rod collars 9 respectively. A return spring 11 is provided on one side of the fixing rod collar 9. One end of the return spring 11 is connected to the inner wall of the fixing rod slot 6-1.

[0033] By setting a fixing rod collar in the fixing rod slot, the fixing rod can be fitted with the fixing rod, and the fixing rod collar will also move along the direction of the slide groove. This can prevent the fixing rod from shaking while moving under the action of the two-way cylinder, thus avoiding friction with the air intake grille and causing wear on the paint surface of the air intake grille.
