Description

Technical Field

[0001] This utility model relates to the field of embossing processing, and more specifically, it relates to a steel stamp pressing and clamping structure. Background Technology

[0002] In the field of metal processing, the stamping clamping structure is a key piece of equipment used to fix workpieces to be processed. It mainly consists of a base, a pressure plate, and a locking mechanism. Traditional stamping clamping structures use screws or quick-clamping clamps to generate pressure to fix the workpiece to the base. While this design can meet basic positioning requirements, it is problematic when processing thin sheet materials. Thin sheet materials are prone to plastic deformation during transportation and storage. When such slightly curved sheets are directly clamped, the pressure plate can only fix the edges of the workpiece, and the area to be stamped will experience localized arching due to residual stress. This arching phenomenon leads to uneven force during stamping, resulting in inconsistent stamp depths or, in severe cases, secondary deformation or even cracking of the sheet material. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel stamp pressing and clamping structure.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel stamp pressing and clamping structure, including a bearing platform and two supporting legs located under the bearing platform. A clamping frame is sleeved on the bearing platform. The clamping frame slides vertically relative to the bearing platform. An adjusting component is provided on the bottom surface of the clamping frame for adjusting the distance between the top surface of the clamping frame and the top surface of the bearing platform. Protective plates are fixedly connected to both sides of the bearing platform. The protective plates are located on one side of the clamping frame. A smoothing block is slidably connected between the protective plates. Both ends of the smoothing block are integrally formed with limiting posts. A sliding groove is provided on the protective plate. The limiting post is slidably connected in the sliding groove. The sliding groove guides the limiting post to move in the horizontal direction. A lifting groove is provided on the protective plate. The end of the sliding groove near the clamping frame is connected to the lifting groove. The lifting groove guides the limiting post to move in the vertical direction.

[0005] The present invention is further configured such that: the adjusting component consists of a threaded rod and a turntable located at the bottom end of the threaded rod; the threaded rod is threadedly connected to the bottom of the clamping frame; the threaded rod passes through the bottom of the clamping frame; and the top end of the threaded rod is rotatably connected to the bottom surface of the bearing platform.

[0006] The present invention is further configured such that: a positioning baffle is slidably connected to the bearing platform, the positioning baffle is located on the side of the clamping frame away from the guard plate, and the positioning baffle slides in the horizontal direction.

[0007] The present invention is further configured such that: a fixing member is fixedly connected to both sides of the positioning baffle, the bottom of the fixing member spans the bottom surface of the bearing platform, and a tightening screw is provided through the side wall of the fixing member, the tightening screw being threadedly engaged with the fixing member.

[0008] The present invention is further configured such that: a stepped groove is provided on the side of the positioning baffle near the clamping frame, and the width of the stepped groove gradually decreases along the direction away from the clamping frame.

[0009] The present invention is further configured such that a lifting block is fixedly connected to the top surface of the smoothing block.

[0010] In summary, this utility model has the following beneficial effects: the flattening block flattens the sheet material, preventing bending and affecting processing quality; both sides of the bottom surface of the flattening block are rounded to prevent scratches during sliding. After flattening, steel stamping can be performed. Because the sheet material is now flat, the steel stamping pressure is evenly distributed, resulting in a clear mark. Attached Figure Description

[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] Example: A steel stamp pressing and clamping structure, such as Figure 1 , Figure 2 As shown, the support platform 1 is made of high-strength cast iron. Vertically mounted guard plates 4 are fixed to both sides of the support platform 1, and grooves 7 are machined through the guard plates 4. A clamping frame 3 surrounds the support platform 1, and its sides fit snugly against the sides of the support platform 1, ensuring stable vertical movement of the clamping frame 3. An adjusting component is installed at the center of the bottom of the clamping frame 3. The adjusting component consists of a threaded rod 9 and a turntable 10 for rotating the threaded rod 9. Several arc-shaped grooves are formed on the side wall of the turntable 10 to increase friction, facilitating rotation of the turntable 10 by the user. Rotation of the turntable 10 allows for precise control of the distance between the clamping frame 3 and the support platform 1, adapting to plates of different thicknesses.

[0015] like Figure 1 , Figure 2 As shown, both ends of the spreading block 5 are provided with cylindrical limiting posts 6, which cooperate with the sliding grooves 7 and lifting grooves 8 on the guard plate 4. The horizontally set sliding grooves 7 allow the spreading block 5 to move back and forth, while the vertical lifting grooves 8 are used to lift the spreading block 5 to place the board. The top of the spreading block 5 is provided with a lifting block 15 for easy operation. The two sides of the lifting block 15 are processed into slightly convex arc surfaces to facilitate lifting.

[0016] like Figure 1 , Figure 2 As shown, an adjustable positioning baffle 11 is provided on one side of the support platform 1, and the baffle is connected to the platform via a fixing member 12 at the bottom. A tightening screw 13 is installed on the fixing member 12, and a knob structure is integrally formed at one end of the tightening screw 13 outside the fixing member 12. The friction between the fixing member 12 and the support platform 1 can be controlled by rotating the tightening screw 13. A special stepped groove 14 is machined on the side of the positioning baffle 11 near the clamping frame 3. This tapered design can adapt to the edges of plates of different sizes, ensuring accurate positioning. All sliding parts of the entire clamping structure are guided by wear-resistant copper sleeves to ensure motion accuracy and service life.

[0017] In operation, the operator first places the sheet material to be processed on the support platform 1, lifts the smoothing block 5 using the lifting groove 8, places the sheet material in, and uses the positioning baffle 11 to confirm the correct position. Then, the operator rotates the adjusting turntable 10 to press the clamping frame 3 against the edge of the sheet material. A rubber pad is fixedly connected to the inner top surface of the clamping frame 3 to prevent the clamping frame 3 from pressing indentations on the sheet material. At this time, the operator pushes the smoothing block 5 to move it horizontally, flattening the sheet material and preventing bending that would affect processing quality. Both sides of the bottom surface of the smoothing block 5 are rounded to prevent scratches during sliding. After flattening, the steel stamping process can be performed. Since the sheet material has been flattened, the steel stamping pressure can be evenly distributed to ensure a clear mark.

All technical solutions falling within the scope of this utility model's concept are protected.
