Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing devices, in particular to a clamp for metal material processing. Background Art

[0002] In the field of metal material processing, especially in the process of steel pipe processing, the clamp is a key tool to ensure the processing accuracy and stability of the workpiece. At present, the widely used steel pipe clamping fixtures on the market mostly use two rectangular clamping plates for clamping. This type of clamp has a simple structure and is easy to operate, which can meet basic clamping needs. However, with the continuous advancement of metal material processing technology, the requirements for processing accuracy and efficiency are increasing. The traditional clamping method can no longer meet the high-precision and high-efficiency processing needs;

[0003] The traditional clamping method of two rectangular clamping plates mainly relies on the pressure of the clamping plates to keep the steel pipe stable during the clamping process. However, since the steel pipe itself has a certain elasticity and deformation ability, during the processing, especially under the condition of large cutting force, the steel pipe is prone to slight deformation, resulting in slight movement of the steel pipe during the processing, resulting in reduced processing accuracy. In addition, for steel pipes with longer lengths or larger diameters, the traditional clamping method often cannot ensure the stability and processing accuracy of the entire steel pipe. Therefore, a clamp for metal material processing is proposed to overcome the above defects. Utility Model Content

[0004] The utility model aims to solve the defect that the existing clamps in the prior art are not convenient for stably clamping metal materials such as stainless steel pipes, and proposes a clamp for processing metal materials.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamp for processing metal materials comprises a processing table. Two electric push rods are installed on the top of the processing table. U-shaped frames are installed at the output ends of the two electric push rods. Clamping parts are arranged on the corresponding sides of the two U-shaped frames.

[0007] A limiting groove is provided in the U-shaped frame, and two ladder blocks are slidably fitted in the limiting groove. A second screw rod passes through the U-shaped frame, and threads in opposite directions are provided at both ends of the second screw rod. Two ladder blocks are threadedly fitted at both ends of the second screw rod, one side of the two ladder blocks is connected to the limiting block, and one side of the two limiting blocks is installed with a positioning block.

[0008] Preferably, a positioning groove is provided on the top of the processing table, a blanking plate is installed in the middle of the processing table, a U-shaped groove is provided in the blanking plate, and a buffer pad is arranged on the blanking plate.

[0009] Preferably, a sliding block is installed at the bottom of the U-shaped frame, and the sliding block is slidably fitted in the positioning groove.

[0010] Preferably, the clamping part has a first screw and a motor, the first screw passes through the U-shaped frame, the motor is installed on the top of the U-shaped frame, the output end of the motor is connected to one end of the first screw, the two ends of the first screw are provided with threads in opposite directions and the threads are matched with moving blocks, and a C-shaped block is installed on one side of the two moving blocks.

[0011] Preferably, a limiting rod is connected to one side of the U-shaped frame, a connecting block is installed on one side of the C-shaped block, and the limiting rod passes through the connecting block.

[0012] Preferably, a rotating block is installed at one end of the second screw.

[0013] The utility model has the following beneficial effects:

[0014] 1. Under the cooperation of the positioning block and the second screw, when clamping the metal steel pipe, the second screw is rotated so that the two ladder blocks drive the positioning block to contact the inner wall of the steel pipe and further limit it. On the basis of the original external clamping, internal support is added, which greatly improves the stability of the steel pipe during processing. The internal and external combined clamping method reduces the slight deformation of the steel pipe caused by cutting force or vibration during processing, thereby significantly improving the processing accuracy. It not only enhances the clamping force of the clamp on the steel pipe, but also enables the clamp to adapt to steel pipes of different diameters and lengths, improving the versatility and adaptability of the clamp;

[0015] 2. Under the cooperation of the U-shaped groove and the blanking plate, after the steel pipe is processed, the motor is started again and the rotating block is rotated so that the C-shaped block and the positioning block release the limit on the inside and outside of the steel pipe respectively. At this time, the electric push rod is started to move the two clamping parts apart, and the steel pipe falls onto the blanking plate due to gravity. After being cushioned by the buffer pad, it rolls to the middle part with the U-shaped groove for collection, avoiding direct falling onto the processing table to cause damage to the steel pipe, thereby increasing the safety of the device and providing better protection for the steel pipe.

After the steel pipe is processed, the motor 402 is started again and the rotating block 601 is rotated so that the C-shaped block 404 and the positioning block 8 respectively release the limit on the inside and outside of the steel pipe. At this time, the electric push rod 2 is started to move the two clamping parts 4 apart, and the steel pipe falls onto the blanking plate 102 due to gravity. After the cushion pad cushions its fall, it rolls to the middle part along the U-shaped groove 103 for collection. Two electric push rods 2 are installed on the top of the processing table 1. The output ends of the two electric push rods 2 are installed with U-shaped frames 3. The bottom of the U-shaped frame 3 is installed with a slider 302. The slider 302 slides in the positioning groove 101. When the electric push rod 2 pushes the U-shaped frame 3, the slider 302 at the bottom of the U-shaped frame 3 slides in the positioning groove 101 to position the movement of the U-shaped frame 3. A limit rod 9 is connected to one side of the U-shaped frame 3. The C-shaped block 404 is A connecting block 10 is installed on one side, and a limiting rod 9 passes through the connecting block 10. When the first screw 401 drives the C-shaped block 404 to move, the connecting block 10 is limited by the limiting rod 9, so that the C-shaped block 404 can only move in the vertical direction. A clamping part 4 is provided on one side corresponding to the two U-shaped frames 3. The clamping part 4 has a first screw 401 and a motor 402. The first screw 401 passes through the U-shaped frame 3, and the motor 402 is installed on the top of the U-shaped frame 3. The output end of the motor 402 is connected to one end of the first screw 401. The first screw 40 1 has threads in opposite directions at both ends and the threads are matched with moving blocks 403, and a C-shaped block 404 is installed on one side of the two moving blocks 403. When clamping the metal material steel pipe, the steel pipe is placed between the two clamping parts 4. At this time, the two electric push rods 2 are started so that the steel pipe is located between the corresponding C-shaped blocks 404, and the positioning blocks 8 are located inside the two ends of the steel pipe. Then the motor 402 is started to drive the first screw 401 to rotate, so that the first screw 401 drives the two moving blocks 403 to move synchronously to the middle and drive the C-shaped blocks 404 to clamp the steel pipe.

[0023] A limiting groove 301 is provided in the U-shaped frame 3, and two ladder blocks 5 are slidably fitted in the limiting groove 301.
