Description

Technical Field

[0001] This utility model belongs to the field of sheet metal clamping technology, specifically a clamping device for processing forged sheet metal parts. Background Technology

[0002] Sheet metal parts are common mechanical parts. When processing them, they need to be fixed on a machine tool. Generally, the position of the clamping plate is adjusted by using a clamping plate and a threaded rod to clamp the sheet metal part between the clamping plates, thereby fixing the sheet metal part and facilitating subsequent processing.

[0003] A patent with publication number CN116787178A discloses a clamping device for processing forged sheet metal parts, including a base. A flipping component is fixedly installed on the top of the base. An adjusting component is disposed through the middle of the flipping component. Upper and lower clamping components are movably connected to the upper and lower sides of the end of the adjusting component. An end clamping component is provided at the end of the adjusting component. Front and rear clamping components are movably connected to the front and rear sides of the end of the adjusting component. By extending the output shaft of a hydraulic cylinder, the slide block slides upward in the slide rail, and the rotating shaft moves upward synchronously, moving the sheet metal part upward. Then, the rotating handle is held to rotate the rotating shaft, thereby causing the sheet metal part to deflect synchronously. When the turntable follows the rotating shaft and rotates 90 degrees, the sliding column is engaged in the V-groove to stabilize the current position of the rotating shaft. Thus, when the sheet metal part rotates 180 degrees, it is stabilized in the current state, thereby achieving the purpose of clamping and fixing the sheet metal part for easy flipping.

[0004] Currently, existing sheet metal sheets are only pressed and fixed on both sides during extrusion, failing to effectively fix the edges and corners. This results in the sheet metal sheet wobbling during positioning due to the pushing force generated during processing, leading to processing defects. Furthermore, because existing sheet metal sheets vary in size, the corner clamping devices cannot effectively align or adjust them during fixing.

[0005] Therefore, a clamping device for processing forged sheet metal parts is proposed to address the above problems. Utility Model Content

[0006] To overcome the shortcomings of existing technologies and solve the above-mentioned problems, a clamping device for processing forged sheet metal parts is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A clamping device for processing forged sheet metal parts according to this utility model includes a processing table and a processing sheet metal plate that is movably attached to the inner side wall of the top of the processing table. A splash-proof top shell is fixedly installed on the outer side surface of the top of the processing table. A fan is fixedly installed on one side surface of the processing table and at the two side edges. A guide air pipe is fixedly connected to the output end of the fan. A return air pipe is fixedly installed at the other end of the guide air pipe on the outer side surface of the top of the processing table. An electric threaded rod one is fixedly installed on the inner side walls of both sides of the splash-proof top shell. A slider is threadedly movably sleeved on the outer side surface of the output end of the electric threaded rod one. An electric threaded rod two is fixedly installed on the outer side surface of the slider. A laser processing head is threadedly movably sleeved on the outer side surface of the electric threaded rod two.

[0008] Preferably, a cavity is provided inside the processing table and at the two side edges, and a hydraulic rod is fixedly installed on the inner wall of the cavity at the two side edges.

[0009] Preferably, a second hydraulic rod is provided on the inner wall of the cavity and at the middle position of the first hydraulic rod, and a double-roller extrusion rod is fixedly installed on one side surface of the processing table.

[0010] Preferably, an L-shaped overlapping arm is fixedly connected to the output end of the hydraulic rod, a threaded rod is fixedly installed on the inner wall of the L-shaped overlapping arm, and a compression push arm is threadedly and movably sleeved on the output end of the threaded rod.

[0011] Preferably, the outer surface of the extrusion push arm is movably attached to the outer surface of the L-shaped overlapping arm, and the bottom surface of the extrusion push arm is oscillatingly connected to a lower swing limit arm that is movably overlapped on the outer surface of the processed sheet metal plate.

[0012] Preferably, a fitting arm plate is fixedly connected to the output end of the hydraulic rod two, and a rectangular snap-fit ​​groove is provided on the inner wall of the fitting arm plate to be movably fitted onto the outer surface of the processed sheet metal plate.

[0013] Preferably, a top-pressure anti-slip plate and an elastic strip are fixedly connected to the bottom inner wall of the rectangular snap-fit ​​groove, the top surface of the elastic strip is fixedly connected to the bottom surface of the top-pressure anti-slip plate, and the top surface of the top-pressure anti-slip plate is movably overlapped with the bottom surface of the processed sheet metal plate.

[0014] Preferably, a power supply box is fixedly installed on the top surface of the splash-proof top shell, the receiving end of the laser processing head is fixedly connected to the output end of the power supply box, and an auxiliary rod is fixedly connected to the outer surface of the slider and located at one edge of the electric threaded rod. The outer surface of the auxiliary rod is movably sleeved on the outer surface of the laser processing head.

[0015] The beneficial effects of this utility model are:

[0016] This utility model provides a clamping device for processing forged sheet metal parts. It works in conjunction with two electric threaded rods to move the slider and laser processing head laterally and vertically, thereby processing different positions of the sheet metal. During processing, a fan blows air into the cavity. A splash-proof top shell is attached to the top surface of the processing table, creating a relatively enclosed environment for the sheet metal. The slots on the outer surface of the cavity discharge the air blown by the fan, and the air accumulates in the inner cavity of the splash-proof top shell. The fan then absorbs the gas through the guide and return air pipes, recovering the gas accumulated inside the splash-proof top shell. As the air circulates within the splash-proof top shell, harmful gases are absorbed, significantly reducing the escape of waste gas generated during sheet metal processing and minimizing the risk of secondary environmental pollution.

[0017] This utility model provides a clamping device for processing forged sheet metal parts. When the hydraulic rod pushes the L-shaped overlapping arm, the shape of the L-shaped overlapping arm is used to fit onto the corners of the sheet metal being processed, thus limiting the four corners of the sheet metal. When encountering small-sized sheet metal, the threaded rod on the inner wall of the L-shaped overlapping arm moves the extrusion pushing arm, allowing the extrusion pushing arm to fit against the small-sized sheet metal without the need for secondary movement of the L-shaped overlapping arm. After the extrusion pushing arm moves out of the cavity, it swings down in conjunction with the lower limit arm. The swinging lower limit arm will then drop vertically, effectively fitting thinner sheet metal where the bottom surface of the extrusion pushing arm cannot reach. Attached Figure Description

[0027] 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.

[0028] Specific implementation examples are given below.

[0029] Please see Figure 1 - Figure 3 and Figure 7This utility model provides a clamping device for processing forged sheet metal parts, including a processing table 11 and a processing sheet metal plate 12 movably overlapping the inner side wall of the top of the processing table 11. A splash-proof top shell 13 is fixedly installed on the outer side surface of the top of the processing table 11. A fan 112 is fixedly installed on one side surface of the processing table 11 and at the two side edges. A guide air pipe 113 is fixedly connected to the output end of the fan 112. A return air pipe 114 is fixedly installed on the other end of the guide air pipe 113 on the outer side surface of the top of the processing table 11. An electric threaded rod 132 is fixedly installed on the inner side walls of both sides of the splash-proof top shell 13. A slider 133 is threadedly movably sleeved on the outer side surface of the output end of the electric threaded rod 132. An electric threaded rod 134 is fixedly installed on the outer side surface of the slider 133. A laser processing head 136 is threadedly movably sleeved on the outer side surface of the electric threaded rod 134.

[0030] During operation, the electric threaded rods 132 and 134 work together to move the slider 133 and the laser processing head 136 laterally and vertically, thereby processing different positions of the sheet metal plate 12. Simultaneously, the blower 112 blows air into the cavity 111. The splash-proof top shell 13 overlaps the top surface of the processing table 11, creating a relatively enclosed environment for the sheet metal plate 12. At this time, the slots on the outer surface of the cavity 111 channel the airflow from the blower 112. The air is discharged and accumulates in the internal cavity of the splash-proof top shell 13. The fan 112 then absorbs the gas inside the guide air pipe 113 and the return air pipe 114 and recovers the gas accumulated inside the splash-proof top shell 13. As the air circulates and is drawn in inside the splash-proof top shell 13, the harmful gases accumulated inside the splash-proof top shell 13 are absorbed, thereby greatly reducing the emission of waste gas generated during the processing of sheet metal 12 and preventing secondary pollution of the surrounding environment.

[0031] Furthermore, such as Figure 1 - Figure 3 and Figures 5 to 7As shown, a cavity 111 is provided inside the processing table 11 and at its two side edges. A hydraulic rod 116 is fixedly installed on the inner wall of the cavity 111 at its two side edges. A hydraulic rod 117 is provided on the inner wall of the cavity 111 at the middle position of the hydraulic rod 116. A double roller extrusion rod 115 is fixedly installed on one side surface of the processing table 11. A fitting arm plate c1 is fixedly connected to the output end of the hydraulic rod 117. A rectangular snap-fit ​​groove c2 is provided on the inner wall of the fitting arm plate c1, which is movably fitted onto the outer surface of the sheet metal plate 12. The bottom inner wall of the rectangular snap-fit ​​groove c2 is... A top-pressure anti-slip plate c3 and an elastic strip c4 are fixedly connected to the surface respectively. The top surface of the elastic strip c4 is fixedly connected to the bottom surface of the top-pressure anti-slip plate c3. The top surface of the top-pressure anti-slip plate c3 is movably overlapped on the bottom surface of the processed sheet metal plate 12. A power supply box 131 is fixedly installed on the top surface of the splash-proof top shell 13. The receiving end of the laser processing head 136 is fixedly connected to the output end of the power supply box 131. An auxiliary rod 135 is fixedly connected to the outer surface of the slider 133 and located on one side edge of the electric threaded rod 134. The outer surface of the auxiliary rod 135 is movably sleeved on the outer surface of the laser processing head 136.

[0032] During operation, the double-roller extrusion rod 115 extrudes the upper and lower surfaces of the sheet metal plate 12 and feeds it into the processing table 11. When the sheet metal plate 12 passes through the double-roller extrusion rod 115, the surface of the sheet metal plate 12 is flattened. At this time, the hydraulic rod 116 and hydraulic rod 117 extend, so that the fitting arm plate c1 on the output end of the hydraulic rod 117 fits onto the outer surface of the sheet metal plate 12 and is located in the middle position. The rectangular snap-fit ​​groove c2 on the outer surface of the fitting arm plate c1 fits onto the surface of the sheet metal plate 12, thereby limiting the position of the sheet metal plate 12. Then, the elastic strip c4 pushes the top pressure anti-slip plate c3 with a reverse elastic force, so that the top surface of the top pressure anti-slip plate c3 fits tightly against the bottom surface of the sheet metal plate 12, thereby increasing the friction and anti-slip effect between the top pressure anti-slip plate c3 and the sheet metal plate 12.

[0033] Furthermore, such as Figures 3 to 5 As shown, an L-shaped overlapping arm a1 is fixedly connected to the output end of the hydraulic rod 116. A threaded rod a2 is fixedly installed on the inner wall of the L-shaped overlapping arm a1. A pressing push arm a3 is threadedly and movably sleeved on the output end of the threaded rod a2. The outer surface of the pressing push arm a3 is movably attached to the outer surface of the L-shaped overlapping arm a1. A lower swing limit arm a4 is swayingly connected to the bottom surface of the pressing push arm a3 and movably overlaps the outer surface of the processed sheet metal plate 12.

[0034] During operation, when the hydraulic rod 116 pushes the L-shaped overlapping arm a1, the shape of the L-shaped overlapping arm a1 is used to fit onto the corners of the processed sheet metal plate 12, thus limiting the four corners of the processed sheet metal plate 12. If a small-sized processed sheet metal plate 12 is encountered, the threaded rod a2 on the inner wall of the L-shaped overlapping arm a1 moves the extrusion pushing arm a3, so that the extrusion pushing arm a3 can fit with the small-sized processed sheet metal plate 12 without the need for secondary movement of the L-shaped overlapping arm a1. At the same time, after the extrusion pushing arm a3 moves out of the cavity 111, it swings down with the lower limit arm a4. After swinging, the lower limit arm a4 will drop vertically, thus effectively fitting some thinner processed sheet metal plates 12 that cannot be contacted by the bottom surface of the extrusion pushing arm a3.

[0035] Working principle: The double roller extrusion rod 115 extrudes the upper and lower surfaces of the sheet metal plate 12 and feeds it into the processing table 11. When the sheet metal plate 12 passes through the double roller extrusion rod 115, the surface of the sheet metal plate 12 is flattened. At this time, the hydraulic rod 116 and hydraulic rod 117 extend, so that the fitting arm plate c1 on the output end of the hydraulic rod 117 fits onto the outer surface of the sheet metal plate 12 and is located in the middle position. The rectangular snap-fit ​​groove c2 on the outer surface of the fitting arm plate c1 fits onto the surface of the sheet metal plate 12, thereby limiting the position of the sheet metal plate 12. Then, the elastic strip c4 pushes the top pressure anti-slip plate c3 with a reverse elastic force, so that the top surface of the top pressure anti-slip plate c3 fits tightly with the bottom surface of the sheet metal plate 12, thereby increasing the friction and anti-slip effect between the top pressure anti-slip plate c3 and the sheet metal plate 12.

[0036] When the hydraulic rod 116 pushes the L-shaped overlapping arm a1, the shape of the L-shaped overlapping arm a1 is used to fit onto the corners of the processed sheet metal plate 12, thus limiting the four corners of the processed sheet metal plate 12. If a small-sized processed sheet metal plate 12 is encountered, the threaded rod a2 on the inner wall of the L-shaped overlapping arm a1 moves the extrusion pushing arm a3, so that the extrusion pushing arm a3 can fit with the small-sized processed sheet metal plate 12 without the need for secondary movement of the L-shaped overlapping arm a1. At the same time, after the extrusion pushing arm a3 moves out of the cavity 111, it swings down with the lower limit arm a4. After swinging, the lower limit arm a4 will be lowered vertically, thus effectively fitting some thinner processed sheet metal plates 12 that cannot be contacted by the bottom surface of the extrusion pushing arm a3.

[0037] Simultaneously, the electric threaded rods 132 and 134 work together to move the slider 133 and laser processing head 136 laterally and vertically, thereby processing different positions of the sheet metal plate 12. During processing, the blower 112 blows air into the cavity 111, while the splash-proof top shell 13 overlaps the top surface of the processing table 11, thus creating a relatively enclosed environment for the sheet metal plate 12. At this time, the slots on the outer surface of the cavity 111 will absorb the air blown by the blower 112. The exhaust air will accumulate in the internal cavity of the splash-proof top shell 13. The fan 112 will then absorb the gas inside the guide air pipe 113 and the return air pipe 114 and recover the gas accumulated inside the splash-proof top shell 13. As the air circulates and is drawn in inside the splash-proof top shell 13, the harmful gases accumulated inside the splash-proof top shell 13 will be absorbed, thereby greatly reducing the emission of exhaust gas generated during the processing of sheet metal 12 and preventing further pollution of the surrounding environment.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
