Description

Technical Field

[0001] The present invention relates to the field of vehicle accessory processing equipment, in particular to a decorative strip cutting device. Background Art

[0002] The structure of some of the upper decorative strips and water-cut decorative strips assembled on the outer surface of the vehicle is relatively complex, with many bends and arc-shaped connections. When further processing the workpiece, it is necessary to ensure that the surface of the workpiece end remains flat and does not deform after cutting. In the existing cutting device for cutting external water-cut decorative strips, two contoured clamping arms are used in conjunction with an oil cylinder to clamp the workpiece to fix the external water-cut decorative strip before cutting. However, when using this structure to position the workpiece, due to the pressure of the oil cylinder, the two contoured clamping arms will quickly complete the clamping action of the end of the external water-cut decorative strip. At the same time, because the contoured clamping arms have a curved contouring surface, this fixing method easily causes the clamping arms to be forcibly embedded in the external water-cut decorative strip, resulting in deformation of the rear end face of the external water-cut decorative strip after punching, affecting the quality and appearance of the workpiece. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a decorative strip cutting device to prevent the workpiece from being deformed during the process of position fixing before cutting.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A trim cutting device includes a clamping mechanism;

[0006] The clamping mechanism includes a contoured slider, a clamping drive mechanism, a fixing seat and a clamping assembly;

[0007] The hinged end of the clamping assembly is hinged to the fixing seat;

[0008] The movable end of the clamping drive mechanism is hinged to the hinged end of the clamping assembly and is slidably connected to the fixed seat for controlling the opening and closing of the clamping assembly;

[0009] The clamping assembly includes a concave die and a convex die arranged opposite to the concave die;

[0010] The profiling slider and the punch are connected in a relatively slidable manner. When the die and the punch are clamped and the profiling slider is pressed against the end of the die away from the clamping drive mechanism, the profiling slider, the die and the punch form a clamping gap that matches the workpiece to be processed.

[0011] The beneficial effects of the present invention are as follows: the present invention cooperates with the profiling slider, the clamping drive mechanism, the fixed seat and the clamping assembly, and controls the opening and closing of the clamping assembly in a sliding manner under the drive of the clamping drive mechanism, thereby clamping the workpiece to be processed, reducing the pressure of the clamping assembly on the workpiece to be processed, and replacing the clamping method of direct pressure of the oil cylinder in the prior art. At the same time, the clamping drive mechanism can control the position of the profiling slider, so that the profiling slider and the punch jointly support the workpiece to be processed, ensuring the flatness of the end face of the workpiece to be processed after cutting, while avoiding the workpiece to be processed from being compressed and deformed. The present invention combines the support function of the profiling slider on the workpiece to be processed in a manner that reduces the clamping pressure, and at the same time reduces the risk of the workpiece to be processed being compressed and deformed during the cutting process, thereby ensuring product quality.

[0025] To illustrate the technical content of the present application, the purposes and effects achieved, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0026] Please refer to Figures 1-8 A decorative strip cutting device comprises a clamping mechanism

[0027] The clamping mechanism comprises a profiling slider, a clamping drive mechanism, a fixed seat and a clamping assembly

[0028] The hinged end of the clamping assembly is hinged to the fixed seat

[0029] The movable end of the clamping drive mechanism is hinged to the hinged end of the clamping assembly and is connected to the fixed seat in a relatively slidable manner, for controlling the opening and closing of the clamping assembly

[0030] The clamping assembly comprises a female die and a male die arranged opposite to the female die

[0031] The profiling slider is connected to the male die in a relatively slidable manner, and when the female die and the male die are closed and the profiling slider is pressed against one end of the female die away from the clamping drive mechanism, the profiling slider, the female die and the male die form a clamping gap matched with the workpiece to be processed

[0032] The working principle of the present application is to reduce the clamping pressure and combine the supporting effect of the profiling slider on the workpiece to be processed, thereby reducing the risk of deformation of the workpiece to be processed during cutting and ensuring product quality

[0033] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention cooperates with the profiling slider, the clamping drive mechanism, the fixed seat and the clamping assembly, and controls the opening and closing of the clamping assembly in a sliding manner under the drive of the clamping drive mechanism to achieve clamping of the workpiece to be processed, reduce the pressure of the clamping assembly on the workpiece to be processed, and replace the clamping method of direct pressure of the cylinder in the prior art. At the same time, the clamping drive mechanism can control the position of the profiling slider, so that the profiling slider and the punch jointly form a support for the workpiece to be processed, thereby ensuring the flatness of the end face of the workpiece to be processed after cutting and avoiding the workpiece to be processed from being compressed and deformed.

[0034] Furthermore, a limiting portion is provided on the side wall in the thickness direction of the punch, and the limiting portion is arranged opposite to the clamping drive mechanism. When the profiling slider abuts against the limiting portion, a clamping gap is formed among the profiling slider, the die and the punch.

[0035] From the above description, it can be seen that the setting of the limiting portion is used to limit the formation of the contoured slider, ensuring that the contoured slider is clamped between the movable end of the clamping drive mechanism and the limiting portion and remains stable, thereby ensuring that during the cutting process of the workpiece to be processed, the contoured slider can maintain a relatively stable position relationship, so as to provide stable support for the workpiece to be processed and avoid compression deformation of the workpiece.

[0036] Furthermore, the punch includes a first clamping arm and a convex portion; the convex portion is arranged on the side of the first clamping arm facing the die, and avoidance grooves are provided at both ends of the convex portion in the length direction.

[0037] As can be seen from the above description, the avoidance groove is provided to provide clearance space for both ends of the workpiece to be processed, thereby improving the matching degree between the workpiece to be processed and the clamping gap.

[0038] Furthermore, the contoured slider includes a slider body and a contoured protrusion; the contoured protrusion is installed on the side of the slider body facing the die; the slider body is provided with a sliding groove, and a limit platform is provided in the thickness direction of the first clamping arm and passes through the sliding groove, and the side of the limit platform facing the clamping drive mechanism is connected to the side wall of the sliding groove through a reset member.

[0039] From the above description, it can be seen that the setting of the sliding groove, the limit platform and the reset part is used to enable the slider body to slide relative to the sliding groove, thereby ensuring that the slider body and the contoured protrusion can be staggered in the sliding direction, so that when the slider body is separated from the punch, it can be quickly reset, which is convenient for the demolding of the workpiece to be punched and the loading of the next workpiece to be punched.

[0040] Furthermore, an avoidance notch is provided at one end of the contoured protrusion close to the clamping drive mechanism.

[0041] It can be seen from the above description that the setting of the avoidance gap is used to provide an assembly space for the end of the workpiece to be punched.

[0042] Furthermore, when the profiling slider is separated from the movable end of the clamping drive mechanism, the projection area of ​​the profiling protrusion of the profiling slider in the thickness direction is located within the projection area of ​​the punch in the thickness direction.

[0043] From the above description, it can be seen that since the contouring slider can be embedded in the recessed part of the workpiece and provide support for the workpiece when the workpiece is cut, and when the external force acting on the contouring slider is removed, the contouring slider is reset, and the projection area of ​​the contouring protrusion can be completely located in the projection area of ​​the punch in the thickness direction, so as to ensure the rapid unloading of the workpiece and the rapid loading of the next workpiece.

[0044] Furthermore, the clamping drive mechanism includes a sliding assembly, a linear motion assembly and an articulated movable assembly; the linear motion assembly is connected to the clamping assembly through the sliding assembly, the sliding assembly is provided with a first slide groove and a second slide groove, and the punch and the die are respectively slidably connected to the first slide groove and the second slide groove through an articulated movable assembly to control the angle between the punch and the die.

[0045] As can be seen from the above description, the linear motion assembly drives the sliding assembly to perform linear motion, thereby controlling the opening and closing of the clamping assembly. Compared to traditional direct hydraulic cylinder pressure, this method not only ensures stable workpiece clamping, but also significantly reduces clamping pressure, minimizing the risk of workpiece deformation. The provision of the first and second chutes further enhances the stability of the clamping assembly during opening and closing.

[0046] Furthermore, a side of the sliding assembly facing the clamping assembly is provided with an avoidance sliding groove matching the hinged end of the clamping assembly.

[0047] It can be seen from the above description that the setting of the avoidance groove is used to provide a clearance space for the linear motion of the sliding component.

[0048] Furthermore, an extension portion for supporting the punch is provided at one end of the sliding assembly away from the linear motion assembly.

[0049] As can be seen from the above description, the extension portion is provided to support the punch, further improving the supporting force on the workpiece, and preventing the punch from being pressed down due to the pressure on the workpiece during the cutting process, thereby preventing the workpiece from being deformed.

[0050] Furthermore, it also includes a bending and cutting mechanism; the bending and cutting mechanism and the clamping mechanism are arranged parallel to each other, and the bending and cutting mechanism is located above the clamping mechanism; the bending and cutting mechanism includes a scimitar, a scimitar driving mechanism and a fixing part; the center of the scimitar is hinged to the fixing part, and the driving end of the scimitar is transmission-connected to the scimitar driving mechanism, and the cutting end of the scimitar can cut the workpiece to be processed along the end of the workpiece to be processed away from the scimitar driving mechanism.

[0051] As can be seen from the above description, the curved cutting mechanism adopts curved cutting instead of traditional straight cutting, and gradually cuts the workpiece to be processed in a circular motion from one end of the workpiece to be processed, thereby reducing cutting pressure and avoiding deformation of the workpiece.

[0052] The present invention is suitable for clamping a workpiece 2 having a bent portion, which in this embodiment mainly refers to an external water-cut decorative strip, the cross section of which is an arc-shaped workpiece 2 with R corners 21 at both ends.

[0053] Please refer to Figures 1-8 , embodiment 1 of the present invention is:

[0054] A decorative strip cutting device includes a clamping mechanism 1; the clamping mechanism 1 includes a profiling slider 11, a clamping drive mechanism 12, a fixed seat 13 and a clamping assembly 14; the hinged end of the clamping assembly 14 is hinged to the fixed seat 13; the movable end of the clamping drive mechanism 12 is hinged to the hinged end of the clamping assembly 14 and is relatively slidably connected to the fixed seat 13, used to control the opening and closing of the clamping assembly 14; the clamping assembly 14 includes a die 141 and a punch 142 arranged opposite to the die 141; the profiling slider 11 and the punch 142 are relatively slidably connected, when the die 141 and the punch 142 are closed and the profiling slider 11 is pressed against the end of the die 141 away from the clamping drive mechanism 12, the profiling slider 11, the die 141 and the punch 142 form a clamping gap 143 that matches the workpiece 2 to be processed. Since one end of the die 141 and the punch 142 is hinged to the fixed seat 13 , when the die 141 and the punch 142 are separated, the die 141 and the punch 142 are in a V shape, that is, an acute angle is formed between the die 141 and the punch 142 .

[0055] In this embodiment, a limiting portion 1422 is provided on the sidewall of the punch 142 in the thickness direction. The limiting portion 1422 is disposed opposite the clamping drive mechanism 12. When the profiling slider 11 abuts the limiting portion 1422, the profiling slider 11, the die 141, and the punch 142 form the aforementioned clamping gap. Specifically, a movable groove 1421 is provided on the sidewall of the punch 142 in the thickness direction for the profiling slider 11 to move. The limiting portion 1422 is disposed on the side of the movable groove 1421 away from the clamping drive mechanism 12. When the clamping drive mechanism 12 removes the pressure on the profiling slider 11, the profiling slider 11 abuts against the side of the movable groove 1421 opposite the limiting portion 1422.

[0056] In this embodiment, the punch 142 includes a first clamping arm 1423 and a protrusion 1424. The protrusion 1424 is located on the side of the first clamping arm 1423 facing the die 141. Both ends of the protrusion 1424 along its length are provided with a relief groove 1425. Specifically, the groove 1411 of the die 141 is provided on one side of the die 141 along its width. Preferably, the relief groove 1425 located on the first clamping arm 1423 mates with the end of the workpiece 2.

[0057] In this embodiment, the contoured slider 11 includes a slider body 111 and a contoured protrusion 112; the contoured protrusion 112 is mounted on the side of the slider body 111 facing the die 141; the slider body 111 defines a sliding slot 113, and the first clamping arm 1423 has a stopper 1426 extending through the sliding slot 113 in the thickness direction. The side of the stopper 1426 facing the clamping drive mechanism 12 is connected to the sidewall of the sliding slot 113 via a reset member 1427. Preferably, the reset member 1427 is a compression spring.

[0058] In this embodiment, an avoidance notch 1121 is provided at one end of the contoured protrusion 112 close to the clamping drive mechanism 12, and the avoidance notch 1121 is used to cooperate with the avoidance groove 1425 close to one end of the clamping drive mechanism 12 to provide a clearance space for the assembly of the workpiece 2.

[0059] In this embodiment, when the contouring slider 11 is separated from the movable end of the clamping drive mechanism 12 , the projection area of ​​the contouring protrusion 112 of the contouring slider 11 in the thickness direction is located within the projection area of ​​the punch 142 in the thickness direction.

[0060] In this embodiment, the clamping drive mechanism 12 includes a sliding component 121, a linear motion component 122 and a hinged movable component 123; the linear motion component 122 is connected to the clamping component 14 through the sliding component 121, and the sliding component 121 is provided with a first slide groove 1211 and a second slide groove 1212. The punch 142 and the die 141 are respectively slidably connected to the first slide groove 1211 and the second slide groove 1212 through a hinged movable component 123 to control the angle between the punch 142 and the die 141. Among them, the articulated movable component 123 includes a sliding member 1231 and an arc-shaped connecting member 1232, one end of the arc-shaped connecting member 1232 is hinged to the punch 142 or the die 141, and the other end of the arc-shaped connecting member 1232 is hinged to the sliding member 1231, and a sliding member 1231 is embedded in the first sliding groove 1211 and the second sliding groove 1212 respectively, so that the sliding component 121 and the punch 142 and the die 141 can slide relative to each other, and the opening and closing control of the punch 142 and the die 141 can be realized during the sliding process.

[0061] In this embodiment, a side of the sliding assembly 121 facing the clamping assembly 14 is provided with an avoidance sliding groove 1213 matching the hinged end of the clamping assembly 14 .

[0062] In this embodiment, an extension portion 1214 for supporting the punch 142 and the contoured slider 11 is provided at one end of the sliding assembly 121 away from the linear motion assembly 122 .

[0063] In this embodiment, it also includes a bending and cutting mechanism 3 and a support 4; the bending and cutting mechanism 3 and the clamping mechanism 1 are arranged parallel to each other, and the bending and cutting mechanism 3 is located above the clamping mechanism 1; the bending and cutting mechanism 3 and the clamping mechanism 1 are both installed on the support 4, and the fixed end of the linear motion component 122 is connected to the support 4.

[0064] In this embodiment, the bending and cutting mechanism 3 includes a scimitar 31, a scimitar driving mechanism 32, and a fixing member 33. The fixing end, fixing member 33, and fixing base 13 of the scimitar driving mechanism 32 are respectively connected to the support 4. The center of the scimitar 31 is hinged to the fixing member 33. The driving end of the scimitar 31 is transmission-connected to the scimitar driving mechanism 32. The cutting end of the scimitar 31 is capable of cutting the workpiece 2 along the end of the workpiece 2 away from the scimitar driving mechanism 32. The scimitar driving mechanism 32 includes a linear driving assembly 311 and a sliding connection block 312. The linear driving assembly 311 is transmission-connected to the sliding connection block 312. The sliding connection block 312 is slidably connected to the fixing member 33. The sliding connection block 312 is defined in a guide groove 3121 perpendicular to the sliding connection block 312. A guide post 3122 is mounted on one side of the scimitar 31 in the thickness direction. The guide post 3122 is slidably embedded in the guide groove 3121. Specifically, the scimitar 31 gradually cuts along the end of the workpiece 2 to be processed that is supported by the profiling protrusion 112. During the cutting process, the profiling protrusion 112 applies a reverse force opposite to the pressure of the scimitar 31 to the workpiece 2 to be processed, thereby playing a supporting role. When the scimitar 31 cuts to the other end of the workpiece 2, the groove 1411 of the die 141 applies a reverse force opposite to the pressure of the scimitar 31 to the workpiece 2. Therefore, during the entire process of cutting the workpiece 2, the workpiece 2 can be supported in all directions, and the risk of deformation thereof is greatly reduced.

[0065] The linear motion assembly 122 and the linear drive assembly 311 are both hydraulic cylinders or pneumatic cylinders.

[0066] The working principle of this embodiment is:

[0067] Place the bent workpiece 2 on the convex portion 1424 of the punch 142, and fit the R corners 21 at both ends of the workpiece 2 into the corresponding avoidance grooves 1425;

[0068] The linear motion assembly 122 extends, and the sliding assembly 121 slides relative to the fixed seat 13. The sliding assembly 121 controls the punch 142 and the die 141 to gradually close the mold. When the punch 142 and the die 141 are completely closed, the linear motion assembly 122 continues to extend, and the sliding assembly 121 presses against the contoured slider 11. The reset member 1427 is compressed until the slider body 111 of the contoured slider 11 presses against the limit portion 1422. The contoured protrusion 112 is embedded in the R angle 21 of the workpiece 2 away from the linear motion assembly 122, so that the workpiece 2 is clamped in the clamping gap.

[0069] The linear drive assembly 311 extends, the sliding connection block 312 extends, and the guide groove 3121 drives the scimitar 31 to rotate around the center of the scimitar 31 through the guide post 3122. At the same time, as the linear drive assembly 311 extends, the guide post 3122 moves downward along the guide groove 3121. At the same time, the cutting end of the scimitar 31 gradually approaches the workpiece 2. The scimitar 31 gradually cuts the workpiece 2 along the end of the workpiece 2 away from the linear motion assembly 122 until the workpiece 2 is cut. The linear drive assembly 311 resets.

[0070] The linear motion assembly 122 retracts, the contoured slider 11 is reset under the push of the reset member 1427 , and the contoured protrusion is withdrawn from the R corner 21 of the workpiece 2 .

[0071] To sum up, the present invention provides a decorative strip cutting device, which adopts a linear motion component to cooperate with a sliding component to realize the opening and closing control of the clamping component, clamps the workpiece in a manner with lower clamping pressure than the existing clamping method, and cooperates with a contoured sliding block to support the workpiece. At the same time, the workpiece is cut in combination with a bending cutting method to reduce the pressure on the workpiece when being cut. Since the bending cutting is a step-by-step cutting from one end of the workpiece to the other end, the workpiece is cut during the cutting process due to the pressure of the curved knife, which can cause the die, punch and contoured slider to apply a reverse force to the workpiece, thereby preventing the workpiece from being compressed and deformed during the cutting process.
