Description

Technical Field

[0001] This utility model belongs to the field of sheet metal cutting and straightening technology, specifically a high-precision sheet metal cutting and straightening device. Background Technology

[0002] Sheet metalworking, a processing technique, lacks a fully defined definition. According to a definition published in a foreign professional journal, it can be defined as: sheet metalworking is a comprehensive cold processing technique for thin metal sheets (usually below 6mm), including shearing, punching / cutting / combined cutting, bending, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is the uniform thickness of the same part. Among these, sheet metal cutting has extremely wide applications.

[0003] Most existing high-precision sheet metal cutting devices use a conveyor belt to drag the sheet metal parts to the bottom of the cutting tool for cutting. Since the sheet metal parts are placed on the conveyor belt but lack fixing, when the tool operates, whenever the tool applies force or friction to the sheet metal parts, the lightweight sheet metal parts, which have insufficient friction, may move, causing deviation, which has a significant impact on the cutting accuracy of the sheet metal parts.

[0004] Therefore, this utility model provides a high-precision sheet metal cutting and straightening device. Utility Model Content

This step, by setting up two second telescopic rods, tracks, and movable wheels, enables the movement of the two translational straightening tables, avoiding the situation where the straightening device cannot be used when the width of the sheet metal part is large. This helps to enhance the applicability and flexibility of the device and improve the quality of sheet metal part cutting.

[0010] Preferably, a limiting block is provided at the end of the track away from the protrusion, and the side wall of the limiting block contacts the side wall of the translational straightening table; the limiting block is fixed to the top of the track by bolts; this step, by setting a limiting block on the track, fixes one of the translational straightening tables, avoiding the situation where two translational straightening tables move at the same time, which is beneficial to the sheet metal cutting work, ensures the efficiency of sheet metal cutting, and reduces safety hazards.

[0011] Preferably, a connecting rod is fixed between the fixing blocks; a connecting rod is fixed between every two adjacent fixing blocks; the two connecting rods are arranged in parallel; this step, by setting the connecting rod, avoids uneven force on multiple fixing blocks, which helps to improve the structural strength of the device and increase its service life.

[0012] Preferably, the surfaces of the driving wheel and the driven wheel are coated with an anti-slip material; this step prevents the sheet metal parts from slipping by spraying the anti-slip material on the surfaces of the driving wheel and the driven wheel, making the movement of the sheet metal parts more stable, thereby improving the cutting accuracy of the sheet metal parts.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 3As shown in the embodiment of this utility model, a high-precision sheet metal cutting and straightening device includes a translation straightening table 1; a first telescopic rod 2 is fixedly connected to the top of the translation straightening table 1; multiple first telescopic rods 2 are arranged in a linear array; a fixing block 3 is fixedly connected to the output end of multiple first telescopic rods 2; rotating rods 6 are rotatably connected to the sides of multiple fixing blocks 3; multiple rotating rods 6 are arranged in parallel; a track 5 is installed on the rotating rod 6 near the fixing block 3; a drive wheel 7 is fixedly connected to the end of the rotating rod 6 away from the fixing block 3; a fixing rod 8 is fixedly connected to the side wall of the translation straightening table 1; multiple fixing rods 8 are arranged in a linear array; a driven wheel 9 is rotatably connected to the end of the fixing rod 8; during operation, the operator can guide the sheet metal between two translation straightening tables 1, place both ends of the sheet metal between the drive wheel 7 and the driven wheel 9, drive the first telescopic rod 2 to change the height of the fixing block 3, so that... The drive wheel 7 and the fixed rod 8 clamp the sheet metal. After the cutting work begins, the operator can drive the track 5 to move. Due to the rotational connection between the rotating rod 6 and the fixed block 3, and the sliding connection between the rotating rod 6 and the track 5, the track 5 can drive the multiple rotating rods 6 to rotate by relying on the friction between itself and the multiple rotating rods 6. The multiple drive wheels 7 rotate synchronously, and the multiple drive wheels 7 provide friction to the sheet metal. The multiple drive wheels 7, in conjunction with the support of the fixed rod 8 at the bottom of the sheet metal and the rotation of the driven wheel 9, realize the movement of the sheet metal. This step achieves the smooth movement of the sheet metal by setting the drive wheels 7 and the driven wheels 9 to cooperate with the cutting of the sheet metal. By setting multiple first telescopic rods 2, the clamping of the drive wheels 7 and the driven wheels 9 is flexible and reliable. The multiple drive wheels 7 and the multiple driven wheels 9 work synchronously, avoiding uneven force on the sheet metal and insufficient support. This is beneficial for correcting the cutting of sheet metal and improving the accuracy and efficiency of sheet metal cutting.

[0025] like Figure 1 As shown, the bottom of the two translational straightening tables 1 is provided with a platform 13; the top of the platform 13 is fixedly connected to a third telescopic rod 14; multiple third telescopic rods 14 are arranged parallel at equal intervals; the output end of the third telescopic rod 14 is fixedly connected to a tray 15; during operation, after the operator clamps the sheet metal part between the driving wheel 7 and the driven wheel 9, the operator can select the number of third telescopic rods 14 corresponding to the size of the sheet metal on the platform 13 and drive the corresponding third telescopic rods 14 so that the top of the tray 15 at the output end of the third telescopic rod 14 lightly touches the bottom surface of the sheet metal. The operator can change the shape of the tray 15 according to the shape of the tool and the sheet metal to prevent the tool from damaging the device. After the sheet metal part is cut, the operator can drive the corresponding third telescopic rod 14 to retract the tray 15. This step, by setting up the platform 13, the third telescopic rod 14 and the tray 15, provides support for the bottom of the sheet metal part, solves the problem of the bottom of the sheet metal part being suspended and easily deformed, which is beneficial to the correction of the sheet metal part cutting and improves the cutting accuracy of the sheet metal part.

[0026] like Figure 1 and Figure 2 As shown, a second telescopic rod 10 is fixedly connected between the two translational straightening tables 1; the two second telescopic rods 10 are arranged in parallel; a moving wheel 16 is rotatably connected to the bottom of each translational straightening table 1; the two moving wheels 16 are arranged in parallel; a track 12 is provided at the bottom of each translational straightening table 1; the two tracks 12 are arranged in parallel. During operation, the operator can adjust the width of the device according to the width of the sheet metal part. When the width of the sheet metal part is large, the two second telescopic rods 10 can be driven to widen the distance between the two translational straightening tables 1, thereby adapting to the width of the sheet metal part and fixing both ends of the sheet metal part between the driving wheel 7 and the driven wheel 9, after which cutting can be performed. This step, by setting up two second telescopic rods 10, tracks 12, and moving wheels 16, realizes the movement of the two translational straightening tables 1, avoiding the situation where the straightening device cannot be used when the width of the sheet metal part is large, which helps to enhance the applicability and flexibility of the device and improve the quality of sheet metal part cutting.

[0027] like Figure 1 and Figure 2 As shown, protrusions 17 are fixed to the ends of the two tracks 12; auxiliary rods 18 are fixed to the ends of the two protrusions 17; the two auxiliary rods 18 penetrate the sides of adjacent translational correction platforms 1 and extend to the translational correction platform 1 away from the protrusions 18; the two auxiliary rods 18 are fixed in parallel to the side wall of the translational correction platform 1 away from the protrusions 18; during operation, when the second telescopic rod 10 retracts or extends, the translational correction platform 1 moves synchronously under the constraint of the two auxiliary rods 18, and the operator adjusts the distance between the two translational correction platforms 1. At the same time, the two second telescopic rods 10 apply force to the two translational correction platforms 1. When the force applied by the second telescopic rods 10 affects the state of the translational correction platform 1, the two auxiliary rods 18 can provide a reaction force to the translational correction platform 1, thereby correcting the state of the translational correction platform 1. This step, by setting the protrusions 17 and the auxiliary rods 18, constrains the state of the translational correction platform 1, preventing the translational correction platform 1 from being subjected to uneven force during movement, causing swaying and structural damage. This helps protect the structure of the device and enhances the stability of the device.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, a limiting block 11 is provided at the end of the track 12 away from the protrusion 17, and the side wall of the limiting block 11 contacts the side wall of the translational straightening table 1; the limiting block 11 is fixed to the top of the track 12 by bolts; during operation, the operator can lock the position of one of the translational straightening tables 1 by fixing the limiting block 11 on the track 12, so that when the distance between the two translational straightening tables 1 changes, only the position of the translational straightening table 1 changes; this step, by setting the limiting block 11 on the track 12 to fix one of the translational straightening tables 1, avoids the situation where the two translational straightening tables 1 move at the same time, which is beneficial to the sheet metal cutting work, ensures the efficiency of sheet metal cutting, and reduces safety hazards.

[0029] like Figures 1 to 3 As shown, connecting rods 4 are fixedly connected between the fixed blocks 3; a connecting rod 4 is fixedly connected between every two adjacent fixed blocks 3; the two connecting rods 4 are arranged in parallel; during operation, after multiple fixed blocks 3 are subjected to force, the two connecting rods 4 can connect the fixed blocks 3 on the two translation correction tables 1 into one unit, so that multiple fixed blocks 3 are evenly stressed; this step, by setting the connecting rods 4, avoids the situation of uneven stress on multiple fixed blocks 3, which is conducive to improving the structural strength of the device and increasing the service life of the device.

[0030] like Figures 1 to 3 As shown, the surfaces of the driving wheel 7 and the driven wheel 9 are coated with anti-slip material. During operation, the driving wheel 7 and the driven wheel 9 coated with anti-slip material can grip the sheet metal parts tightly, providing greater gripping force. This step prevents the sheet metal parts from slipping by coating the surfaces of the driving wheel 7 and the driven wheel 9 with anti-slip material, making the movement of the sheet metal parts more stable, thereby improving the cutting accuracy of the sheet metal parts.

[0031] During operation, the operator guides the sheet metal between two translational straightening tables 1, placing both ends of the sheet metal between the drive wheel 7 and the driven wheel 9. The operator then drives the first telescopic rod 2 to change the height of the fixed block 3, causing the drive wheel 7 and the fixed rod 8 to clamp the sheet metal. After the cutting operation begins, the operator drives the track 5. Due to the rotational connection between the rotating rod 6 and the fixed block 3, and the sliding connection between the rotating rod 6 and the track 5, the track 5, after moving, can rely on the friction between itself and multiple rotating rods 6 to drive multiple rotating rods 6 to rotate. Multiple drive wheels 7 rotate synchronously, and multiple drive wheels 7 provide friction to the sheet metal. Wheel 7, in conjunction with the support of the sheet metal bottom fixing rod 8 and the rotation of the driven wheel 9, enables the movement of the sheet metal. After the operator clamps the sheet metal part between the driving wheel 7 and the driven wheel 9, they can select the corresponding number of third telescopic rods 14 on the platform 13, and drive the corresponding third telescopic rods 14 so that the top of the output tray 15 of the third telescopic rod 14 lightly touches the bottom surface of the sheet metal. The operator can change the shape of the tray 15 according to the shape of the tool and the sheet metal to prevent the tool from damaging the device. After the sheet metal part is cut, the operator can drive the corresponding third telescopic rod 14 to retract the tray 15. The operator can adjust the mounting according to the width of the sheet metal part. The width of the sheet metal part is adjusted as needed. When the width of the sheet metal part is large, the two second telescopic rods 10 can be driven to widen the distance between the two translational straightening tables 1, thereby accommodating the width of the sheet metal part. The two ends of the sheet metal part are fixed between the driving wheel 7 and the driven wheel 9, and then cutting can be carried out. When the second telescopic rods 10 retract or extend, the translational straightening tables 1 move synchronously under the constraint of the two auxiliary rods 18. When the operator adjusts the distance between the two translational straightening tables 1, the two second telescopic rods 10 simultaneously apply force to the two translational straightening tables 1. When the force applied by the second telescopic rods 10 affects the state of the translational straightening tables 1, Two auxiliary rods 18 can provide reaction force to the translational straightening table 1, thereby correcting the state of the translational straightening table 1. The operator can lock the position of one of the translational straightening tables 1 by fixing the limit block 11 to the track 12, so that when the distance between the two translational straightening tables 1 changes, only the position of the translational straightening table 1 changes. After the multiple fixed blocks 3 are affected by the force, the two connecting rods 4 can connect the fixed blocks 3 on the two translational straightening tables 1 into one, so that the multiple fixed blocks 3 are evenly stressed. The active wheel 7 and the driven wheel 9, which are coated with anti-slip material, can firmly grip the sheet metal parts and provide greater gripping force to the sheet metal parts.
