Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a pressing mechanism. Background Art

[0002] When metal strips are processed by coil stamping, tube making, cutting and other processes, it is often necessary to change the rolls to continue processing after the use of a roll of strips. The conventional operation is to extract the tail of the previous roll from the strip unwinding and leveling conveyor line after the processing is completed, and then re-thread the material, which takes a long time, affects continuous work, and wastes the tail on the conveyor line. It is not only time-consuming and labor-intensive, but also reduces processing efficiency and increases equipment costs.

[0003] In order to solve the above problems, a device that can weld the head and tail of the material strip can be designed. However, when using this device, if the head material is not pressed in a suitable position first, when the cutting equipment and welding equipment are used to cut the waste material and weld the head and tail material, the material strip is easily moved by force, which affects the efficiency and effect of the material strip splicing. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a clamping mechanism, which is used to adjust the position and clamp the head material when welding the head and tail of the material strip.

The benefit is that the specific connection method between the piston rod of the cylinder and the connection port of the clamping plate is further described, and the operation of the cylinder can drive the clamping plate to rise and fall through its piston rod.

[0008] In some embodiments, two sliding assemblies are further included, and the two ends of the pad on the feeding side are respectively connected to the tops of the two sliding assemblies. The benefit is that the sliding assembly can support the pad on the feeding side.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3 As shown, the clamping mechanism mainly includes two clamping plates 1, two pads 2, four cylinders 3 and two servo screws 4. The two clamping plates 1 are arranged horizontally side by side, one of which is located at the side where the material plate enters (called the feeding side), and the other clamping plate 1 is located at the side where the material plate passes out (called the discharging side).

[0021] Two clamping plates 1 are placed on two pads 2 respectively. Among them, four cylinders 3 are respectively installed at the bottom of both ends of the two pads 2, and the piston rod of each cylinder 3 is located at the top thereof, and respectively penetrates each pad 2 and is connected to the clamping plate 1 above. Therefore, the operation of each cylinder 3 can drive each clamping plate 1 to rise and fall, so as to cooperate with the pad 2 where it is located to clamp or loosen the passing material sheet.

[0022] Preferably, connecting ports 5 are provided at the bottom of both ends of each clamping plate 1, and each connecting port 5 is respectively connected to the piston rod of each cylinder 3, that is, the piston rod of each cylinder 3 extends into and is connected to each connecting port 5 (for the convenience of display, the two are in a separated state in the figure).

[0023] The two servo screws 4 extend from the feeding side to the discharging side, and the two ends of the pad 2 on the feeding side are respectively mounted on the two servo screws 4. Under the operation of the two servo screws 4, the clamping plate 1 and the pad 2 on the feeding side can be moved. In the case where the clamping plates 1 and the pad 2 on both sides clamp the head material and the tail material respectively, the head material and the tail material can be butted by moving the clamping plate 1 and the pad 2 on the feeding side and cooperating with cutting, welding and other processing operations.

[0024] The material sheet on it is driven to approach or move away from the pressing plate 1 and the pad 2 on the discharge side, thereby moving the material sheet to a position suitable for cutting and welding, and completing docking with other material sheets.

[0025] Preferably, the stroke of the servo screw 4 is 100 mm.

[0026] In addition, two sliding components 6 can be provided, and the two ends of the pad 2 on the feed side can be connected to the tops of the two sliding components 6 respectively, so as to support the pad 2 and the clamping plate 1 on the feed side and ensure their smooth movement.

[0027] The sliding assembly 6 is composed of a slider 7 and a slide rail 8, the slider 7 is slidably mounted on the slide rail 8, and the pad 2 is fixedly connected to the slider 7. The extension direction of each slide rail 8 is consistent with each screw rod 4, that is, they are all perpendicular to each pad 2.

[0028] Preferably, considering that the overall structure of the equipment where the clamping mechanism is located is often complex, in order to ensure that the clamping plate 1 and the pad 2 can be arranged horizontally, the servo screw rod 4 and the sliding assembly 6 on one side can be installed on a plurality of support blocks 9 with appropriate heights as needed, so that the heights of both ends of each clamping plate 1 and the pad 2 are adjusted to be consistent. In general, support blocks 9 are provided at the bottom of both ends of the servo screw rod 4 and the sliding assembly 6.

[0029] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
