Designers design the shape, size, color and material of the bright trims according to the overall style of the car and customer needs. During the processing of chrome-plated metal trims, bending equipment is required to perform bending operations to form different curvatures and contours of the chrome-plated metal trims, making them suitable for vehicle installation.

[0003] The stretching and bending equipment is generally only suitable for the simultaneous stretching and bending of both ends of chrome-plated automobile metal trim strips, which requires the chrome-plated automobile metal trim strips to be longer. Since the structure for fixing the chrome-plated automobile metal trim strips is located in the middle of the mold, the shorter chrome-plated automobile metal trim strips cannot meet the operation requirements of the stretching and bending equipment. In addition, different molds need to be replaced to process chrome-plated automobile metal trim strips of different specifications, which is troublesome to replace and affects the processing efficiency. Therefore, we have designed a stretching and bending device and method for chrome-plated automobile metal trim strips before spraying.

[0015] A method for bending a chrome-plated automobile metal trim wire before spraying, the bending method steps are as follows:

[0016] Step 1: Place the chrome-plated automotive metal trim strip for double-end drawing and bending processing on the corresponding mold body, then extend the corresponding cylinder 4 to push the L-shaped movable seat cover on the mold body, then extend the cylinder 5 to make the clamping plate and the rubber pad against the middle of the chrome-plated automotive metal trim strip to fix the chrome-plated automotive metal trim strip; when the chrome-plated trim strip at one end is drawn and bent, the chrome-plated trim strip is shorter at this time, turn on the motor 3 to drive the threaded rod 2 to rotate, so that the threaded sleeve 2 connected by the thread drives the fixed trim strip assembly to move to one side, so that the fixed trim strip assembly moves to the appropriate position, and then the cylinder 4 extends to make the L-shaped movable seat cover on the top of the mold body, and then the cylinder 5 extends to make the clamping plate and the spring and the mold body In coordination with fixing the chrome-plated automobile metal trim, the clamping plate will drive the shaft block to rotate in the inner cavity of the shaft seat due to the fit between the chrome-plated automobile metal trim and the inner wall of the mold body. Since the inner walls on both sides of the mold body are in an arc-shaped state, for single-sided bending, the clamping plate will move to a position corresponding to the inner wall of the side of the mold body. When the clamping plate contacts the automobile metal trim during the extension of the cylinder 5, the automobile metal trim contacts the arc-shaped inner wall of the mold body, and the automobile metal trim will be offset, which will cause the clamping plate to rotate. During this period, the clamping plate will stretch the spring on one side and squeeze the spring on the other side, so that the rotation of the clamping plate is more closely fitted to the chrome-plated automobile metal trim, and the chrome-plated automobile metal trim is firmly fixed;

[0017] Step 2: Motor 1 drives threaded rod 1 to rotate, threaded sleeve 1 moves back and forth in the inner cavity of fixed frame 1 due to the thread, threaded sleeve 1 drives the moving seat to slide back and forth on the surfaces of two fixed rails, and the moving seat drives the angle plate, cantilever beam, sliding seat, driving assembly, drag chain lifting structure, lifting sleeve, movable square rod, reduction motor, electric clamp, fixed square rod and cylinder to move back and forth through moving and adjusting the bending assembly, and the drag chain lifting structure drives the lifting sleeve, movable square rod, reduction motor, electric clamp, fixed square rod and cylinder to move up and down, so that the clamping port on the electric clamp is aligned with the chrome-plated automobile metal trim, and then motor 2 drives gear 2 to rotate, and the fixed rack 2 makes motor 2 and gear 2 drive the sliding seat to move from the surface of the cantilever beam to the fixed platform, so that the electric clamp is sleeved on the surface of the chrome-plated automobile metal trim, and then the clamping operation is performed;

[0018] Step three: When the cylinder is extended or shortened, it will drive the rack to slide in the inner cavity of the fixed shell, and then drive the meshing gear to rotate clockwise or counterclockwise. The gear drives the angle plate to rotate through the shaft rod, and the angle plate drives the cantilever beam, sliding seat, drive assembly, drag chain lifting structure, lifting sleeve, movable square rod, reduction motor, electric clamp, fixed square rod and cylinder to rotate at an angle. The drag chain lifting structure makes the lifting sleeve, movable square rod, reduction motor, electric clamp, fixed square rod and cylinder move up and down. Then the electric clamp cancels the clamping and cooperates with the extension and shortening of cylinder three, so that the electric clamp can be clamped in multiple positions of the chrome-plated automobile metal trim. The output shaft of the reduction motor will also drive the electric clamp to rotate, so that the chrome-plated automobile metal trim can be stretched and bent in multiple directions. Both ends can be stretched and bent at the same time, or one-sided stretching and bending can be performed.

[0019] 1. The beneficial effects of the present invention are as follows: the present invention adjusts the position of the fixed trim strip assembly through the position adjustment assembly, so that the fixed trim strip assembly can be suitable for fixing chrome-plated automobile metal trim strips of various specifications, so that it can be suitable for the stretching and bending operations of shorter chrome-plated automobile metal trim strips. By moving and adjusting the coordination of the bending assembly and the drag chain lifting structure, the electric clamp can be aligned with the chrome-plated automobile metal trim strips on the two mold bodies. When processing a chrome-plated automobile metal trim strip, the other mold body can be replaced according to demand, and the stretching, bending and disassembly can be achieved at the same time to improve efficiency. The structure of the fixed chrome-plated automobile metal trim strip can adjust the position, and can be suitable for single-end processing of shorter chrome-plated automobile metal trim strips. Moreover, the processing table can install two specifications of molds at one time, and the stretching and bending structures can match them, so that the processing efficiency is improved.

[0020] 2. The present invention can avoid direct contact between the pressing plate and the chrome-plated automobile metal trim strips and damage to the chrome-plated automobile metal trim strips by setting the rubber pad. The rubber pad can not only improve the fixing effect of the pressing plate on the chrome-plated automobile metal trim strips, but also protect the chrome-plated automobile metal trim strips and effectively avoid scratches;

[0021] 3. The present invention provides two springs to ensure that the clamping plate is in a vertical state with respect to the output end of the cylinder 5 when the clamping plate is not subjected to force, thereby ensuring that the clamping plate will not swing randomly when it is not subjected to force, thereby affecting the movement of the clamping plate;

[0022] 4. The present invention uses a limit slider in conjunction with a limit slot. When the L-shaped movable seat moves up and down, the limit slider will be driven to slide in the inner cavity of the limit slot, thereby avoiding deviation during the up and down movement of the L-shaped movable seat and improving the stability of the up and down movement of the L-shaped movable seat.

[0041] Step 1: Place the chrome-plated automobile metal trim strip for double-end drawing and bending processing on the corresponding mold body 18, then the corresponding cylinder four 192 is extended to push the L-shaped movable seat 193 to cover the mold body 18, and then the cylinder five 194 is extended to make the clamping plate 197 and the rubber pad 199 against the middle of the chrome-plated automobile metal trim strip to fix the chrome-plated automobile metal trim strip; when the chrome-plated trim strip at one end is drawn and bent, the chrome-plated trim strip is shorter at this time, turn on the motor three 204 to drive the threaded rod two 202 to rotate, so that the threaded sleeve two 203 connected by the thread drives the fixed trim strip assembly 19 to move to one side, so that the fixed trim strip assembly 19 moves to the appropriate position, and then the cylinder four 192 is extended to make the L-shaped movable seat 193 cover the top of the mold body 18, and then the cylinder five 194 is extended to make the clamping plate 197 and the spring 198 and the mold body 18 In order to fix the chrome-plated automobile metal trim, the clamping plate 197 will drive the shaft block 196 to rotate in the inner cavity of the shaft seat 195 due to the fit between the chrome-plated automobile metal trim and the inner wall of the mold body 18. Since the inner walls on both sides of the mold body 18 are in an arc state, during single-sided bending, the clamping plate 197 will move to a position corresponding to the inner wall of the side of the mold body 18. When the clamping plate 197 contacts the automobile metal trim during the extension of the cylinder 5 194, the automobile metal trim contacts the arc-shaped inner wall of the mold body 18, and the automobile metal trim will be offset, which will cause the clamping plate 197 in contact with the automobile metal trim to rotate.

5. A method for bending a chrome-plated automobile metal trim wire before spraying, which is applied to the device for bending a chrome-plated automobile metal trim wire before spraying as claimed in claim 4, and the bending method has the following steps: Step 1: Place the chrome-plated automobile metal trim strip for double-end bending processing on the corresponding mold body (18), then extend the corresponding cylinder 4 (192) to push the L-shaped movable seat (193) to cover the mold body (18), and then extend the cylinder 5 (194) so ​​that the clamping plate (197) and the rubber pad (199) are pressed against the middle of the chrome-plated automobile metal trim strip to fix the chrome-plated automobile metal trim strip; when the chrome-plated automobile metal trim strip at one end is bent, the chrome-plated automobile metal trim strip is The decorative strip is short, and the motor 3 (204) is turned on to drive the threaded rod 2 (202) to rotate, so that the threaded sleeve 2 (203) connected by the thread drives the fixed decorative strip assembly (19) to move to one side. After the fixed decorative strip assembly (19) moves to a suitable position, the cylinder 4 (192) extends, so that the L-shaped movable seat (193) covers the top of the mold body (18), and then the cylinder 5 (194) extends, so that the clamping plate (197) and the spring (198) are in contact with each other. The mold body (18) cooperates to fix the chrome-plated automobile metal trim strip. The pressing plate (197) drives the rotating shaft block (196) to rotate in the inner cavity of the rotating shaft seat (195) due to the fit between the chrome-plated automobile metal trim strip and the inner wall of the mold body (18). Since the inner walls on both sides of the mold body (18) are in an arc-shaped state, when bending on one side, the pressing plate (197) will move to a position corresponding to the inner wall of the side of the mold body (18). The cylinder 5 (194) is pressed during the extension process. When the clamping plate (197) contacts the automobile metal trim, the automobile metal trim contacts the arc-shaped inner wall of the mold body (18), and the automobile metal trim is offset, which in turn causes the clamping plate (197) to rotate. During this period, the clamping plate (197) stretches the spring (198) on one side, and the spring (198) on the other side is squeezed, so that the rotation of the clamping plate (197) is more closely fitted to the chrome-plated automobile metal trim, thereby firmly fixing the chrome-plated automobile metal trim; Step 2: The motor 1 (610) drives the threaded rod 1 (68) to rotate, and the threaded sleeve 1 (69) moves forward and backward in the inner cavity of the fixed frame 1 (67) due to the thread. The threaded sleeve 1 (69) drives the movable seat (4) to slide forward and backward on the surfaces of the two fixed rails (3). The movable seat (4) drives the angle plate (5), the cantilever beam (7), the sliding seat (8), the driving assembly (9), the drag chain lifting structure (10), the lifting sleeve (11), the movable square rod (12), the reduction motor (13), the electric clamp (14), the fixed square rod (15) and the cylinder 3 (16) to move forward and backward by moving the bending adjustment assembly (6). The drag chain lifting structure (10) drives the lifting sleeve (11), the movable square rod (12), the reduction motor (13), the electric clamp (14), the fixed square rod (15) and the cylinder three (16) to move up and down, so that the clamping opening on the electric clamp (14) is aligned with the chrome-plated automobile metal trim strip, and then the motor two (93) drives the gear two (94) to rotate, and the fixed rack two (92) enables the motor two (93) and the gear two (94) to drive the sliding seat (8) to move on the surface of the cantilever beam (7) toward the fixed platform (1), so that the electric clamp (14) is sleeved on the surface of the chrome-plated automobile metal trim strip, and then the clamping operation is performed; Step 3: The extension or contraction of cylinder 1 (65) drives rack 1 (64) to slide in the inner cavity of fixed shell (63), thereby driving gear 1 (62) in meshing state to rotate clockwise or counterclockwise. Gear 1 (62) drives angle plate (5) to rotate through shaft (61). Angle plate (5) drives cantilever beam (7), sliding seat (8), drive assembly (9), drag chain lifting structure (10), lifting sleeve (11), movable square rod (12), reduction motor (13), electric clamp (14), fixed square rod (15) and cylinder 3 (16) to rotate at an angle. The structure (10) enables the lifting sleeve (11), the movable square rod (12), the reduction motor (13), the electric clamp (14), the fixed square rod (15) and the cylinder three (16) to move up and down, and then the electric clamp (14) cancels the clamping and cooperates with the cylinder three (16) to extend and shorten, so that the electric clamp (14) can be clamped at multiple positions of the chrome-plated automobile metal trim. The output shaft of the reduction motor (13) also drives the electric clamp (14) to rotate, so that the chrome-plated automobile metal trim can be stretched and bent in multiple directions, and the two ends can be stretched and bent at the same time, or one side can be stretched and bent.
