[0005] a base, which is slidably mounted on the bracket;

[0006] A plurality of movable clamping claws movably mounted on both sides of the base;

[0007] A plurality of fixed jaws, which are fixedly mounted on both sides of the base and are used to clamp the material delivered by the movable jaws;

[0008] A first driving member is installed on the base and drives the movable clamping jaw to move closer to or away from the fixed clamping jaw.

[0009] The bracket is also provided with a second driving member for driving the base to move, and the motion trajectory of the base and the motion trajectory of the movable clamping claw are perpendicular to each other.

[0010] The output end of the first driving member is connected to a crossbeam, and both ends of the crossbeam are provided with mounting plates for mounting the movable clamping claws.

[0011] An adjustment groove is provided on the upper surface of the crossbeam along the length direction, and a fastener is provided between the mounting plate and the adjustment groove to connect the two.

[0012] Side plates are installed on both sides of the base, and a number of rotatably installed guide rollers for feeding are provided on the side plates. The guide rollers are equipped with guide plates for adjusting the feeding direction of the materials and rings for fixing the position of the guide plates.

[0013] The base is provided with a support plate and a cover plate stacked up and down. There is a gap between the support plate and the cover plate for the movement of materials and the gap corresponds to the movement track of the movable clamping claw.

[0014] A plurality of guide wheels are provided on both sides of the support plate.

[0021] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0022] As shown in the figure, a coil feeding structure includes a bracket 1 and a feeding mechanism slidably mounted on the bracket 1. The feeding mechanism includes:

[0023] A base 2 is slidably mounted on the bracket 1;

[0024] A plurality of movable clamping jaws 4 are movably mounted on both sides of the base 2;

[0025] Several fixed jaws 3, which are fixedly installed on both sides of the base 2 and are used to clamp the materials delivered by the movable jaws 4;

[0026] The first driving member 5 is installed on the base 2 and drives the movable jaw 4 to move closer to or away from the fixed jaw 3. The technical solution drives the movable jaw to move closer to or away from the fixed jaw through the first driving member. When the movable jaw clamps the material and moves toward the fixed jaw, the fixed jaw is in an open state. When the movable jaw moves to the limit close to the fixed jaw position and stops, the fixed jaw changes to a closed state and clamps the material, while the movable jaw releases the material and returns to its original position. This reciprocating action can accurately push the material into the next stamping process, and has the advantages of accurate feeding and good working stability.

[0027] In addition, there are installation feet under the bracket to adjust the overall height and level of the structure.

[0028] Among them, the material in this technical solution is coiled material.

[0029] The bracket 1 is also provided with a second driving member 6 for driving the base 2 to move. The movement trajectory of the base 2 is perpendicular to the movement trajectory of the movable clamp 4. The second driving member drives the base to move in the Y-axis direction, and the first driving member controls the movement of the material in the X-axis direction. The second driving member can be turned on and off according to actual production conditions. When the second driving member is turned on, it can cooperate with the first driving member to realize oblique feeding of the material.

[0030] The second driving component 6 adopts a ball screw pair and a servo motor, and the first driving component 5 adopts a servo linear module, which has the advantages of high precision, high speed and high response capability.

[0031] The output end of the first driving member 5 is connected to a crossbeam 7 , and mounting plates 9 for mounting the movable clamping jaws 4 are provided at both ends of the crossbeam 7 . The first driving member drives the crossbeam and the movable clamping jaws on the mounting plates to perform reciprocating linear movement.

[0032] An adjustment groove 10 is provided on the upper surface of the crossbeam 7 along the length direction, and a fastener (not shown) is provided between the mounting plate 9 and the adjustment groove 10 to connect the two. The fasteners are bolts and nuts. The crossbeam in this embodiment is made of purchased aluminum profiles, and its surface has adjustment grooves along the length direction for fastener installation. The two mounting plates on the crossbeam are adjusted to a distance according to actual conditions, and then tightened and fixed by fasteners, which has the advantages of low cost, easy installation and easy adjustment.

[0033] Side plates 11 are installed on both sides of the base 2, and a number of rotatably installed guide rollers 12 for feeding are provided on the side plates 11. The guide rollers 12 are equipped with guide plates 13 for adjusting the feeding direction of the materials and sleeves 14 for fixing the position of the guide plates 13. The sleeves are purchased parts, which have a notch and are firmly mounted on the guide rollers by tightening bolts. The sleeves are fixedly connected to the guide plates. When adjusting the spacing between the guide plates, loosen the bolts on the sleeves to adjust the position along the axial direction of the guide rollers. After determining the position, tighten the bolts on the sleeves to firmly hold the guide rollers.

[0034] In addition, the guide roller is made of aluminum alloy as the basic material, and the surface is sprayed with low-friction and wear-resistant material.

[0035] The base 2 is provided with a support plate 15 and a cover plate 16 stacked up and down. There is a gap between the support plate 15 and the cover plate 16 for the material to move and corresponds to the movement trajectory of the movable clamping jaw 4. Maintaining an appropriate gap between the support plate 15 and the cover plate 16 can ensure the smooth passage of the coiled material and prevent the coiled material from deforming and bulging.

[0036] A number of guide wheels 17 are provided on both sides of the support plate 15. The guide wheels can be selected independently and can be adjusted to the left and right positions according to the width of the coil. There are various ways to install the guide wheels. They can be connected to the support plate or the cover plate, or they can be installed on the base. The guide wheel in this embodiment is installed by installing a long strip of aluminum profile on the base, and the guide wheels are rotatably installed at both ends of the aluminum profile. The left and right position adjustment method is the same as that of the mounting plate 9.

[0037] The fixed jaw 3 and the movable jaw 4 have the same structure and both include a cylinder 18, a fixed clamp 19 installed on the cylinder and a movable clamp 20 installed on the piston rod of the cylinder. The fixed jaw is also installed on the aluminum profile like the movable jaw, but the aluminum profile for installing the fixed jaw is fixedly installed on the base. The adjustment method of the fixed jaw and the movable jaw is the same. In this embodiment, the fixed jaw and the movable jaw can also use other clamping parts, such as finger cylinders.

[0038] The coil passes through the guide roller and enters the channel between the cover plate and the support plate under the guidance of the guide plate. The movable jaw tightens the coil and is driven by the first drive member to send the coil forward. At this time, the fixed jaw is in the open state. When the first drive member completes the set feed amount, the fixed jaw actuates to clamp the coil. When the fixed jaw is tightened, the movable jaw opens, and the first drive member drives the movable jaw back to the starting position, waiting for the next feeding action.

[0039] According to the feeding direction setting requirements, when the first driving member is feeding forward and backward, the second driving member can simultaneously perform left and right feeding.
