Description

Technical Field

[0001] This utility model relates to the field of double-sided shearing technology, and in particular to a feeding structure for a rolling-cutting double-sided shear. Background Technology

[0002] Double-sided shearing and pressing equipment is mainly used in the steel plate processing process to achieve precise control of the steel plate width by cutting the two sides of the steel plate. Double-sided shearing and pressing equipment is widely used in the steel processing industry, especially in the finishing line of medium and heavy plate rolling mills, for precise edge cutting of steel plates.

[0003] In the existing double-sided shear feeding structure for rolling cutters, there are still some problems. After the steel plate is cut, it is conveyed to the front end through the conveying structure. However, due to the uneven bottom of the steel plate, part of the roller does not contact the steel plate during the conveying process, which may affect the stability and efficiency of the conveying. Moreover, the roller is prone to wear after contacting the steel plate, and the cost of replacing the roller is relatively high. Therefore, those skilled in the art have provided a feeding structure for double-sided shears for rolling cutters to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a roller-cutting double-sided shear feeding structure. This structure incorporates multiple springs, connecting seats, and rubber pads. The springs push the connecting seats to move outwards from the rollers, while the rubber pads increase the friction between the rollers and the steel plates. During the conveying process, the rubber pads move the steel plates, and they are easy to replace after wear, thus preventing the high cost of replacing worn rollers.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding structure for a double-sided shearing with a rolling cutter, comprising two main equipment units, which are arranged symmetrically in a horizontal arrangement, a support component is provided between the two main equipment units, a base is provided at the front end of the support component, and a conveying structure is provided on the upper surface of the base;

[0006] The conveying structure includes multiple brackets and multiple support frames. The multiple brackets are arranged in pairs, and the multiple sets of brackets and multiple support frames are arranged in a crisscross pattern on the upper surface of the base. A servo motor is fixedly connected inside each of the multiple brackets on one side. A roller is fixedly connected to the output end of each of the multiple servo motors. Multiple grooves are provided on the outer wall of each of the multiple rollers. A spring is fixedly connected to one end of each of the multiple grooves near the center of the roller shaft. A connecting seat is fixedly connected to the other end of each of the multiple springs. A rubber pad is provided on the other side of each of the multiple connecting seats.

[0007] The above technical solution involves starting multiple servo motors, which drive multiple rollers to rotate. A steel plate is placed on the outside of multiple rubber pads, which rotate with the rollers, thus moving the steel plate towards the front of the main unit. During the conveying process, the steel plate squeezes the rubber pads, which in turn squeeze the connecting seat and spring. The tension of the spring pushes the connecting seat and rubber pad towards the position of the steel plate, facilitating support for uneven areas on the bottom of the steel plate.

[0008] Furthermore, each of the multiple rubber pads has an installation groove at the center of its end face away from the multiple rollers, and each of the multiple installation grooves has a limiting screw inside. The multiple limiting screws pass through the multiple installation grooves and extend to one end face of the multiple rubber pads, and their ends are threaded to one end face of the multiple connecting seats.

[0009] With the above technical solution, after the rubber pad wears out, the new rubber pad can be fixed by removing the limiting screw, which facilitates the replacement of the rubber pad and prevents the problem of high replacement cost after the roller directly contacts the steel plate and wears out.

[0010] Furthermore, multiple drive rods are provided on one wall of each of the two main equipment units on both sides of the support assembly. Two conveying assemblies are provided between the multiple drive rods and the support assembly. Two waste collection assemblies are provided on the outside of the multiple drive rods. The two waste collection assemblies include four bearings. The four bearings are respectively sleeved on the outside of the four drive rods at the front and rear ends, and their outer rings are respectively fixedly connected to one side wall of the two main equipment units.

[0011] With the above technical solution, during use, the steel plate is conveyed to the front end through the support and conveying components between the two main equipment hosts.

[0012] Furthermore, each of the four bearings has a connecting ring fixedly connected to the inner ring of one end face near the support assembly, and an internal gear is fixedly connected inside each of the four connecting rings. An external gear is fixedly sleeved on the outer wall of each of the two drive rods at the rear. A planetary gear is provided at the rear end of each of the two external gears. A conveyor belt is provided on one side of each of the two conveying assemblies, and the two conveyor belts are respectively sleeved on the outside of the four connecting rings.

[0013] The above technical solution uses two external gears to drive two planetary gears to rotate, and the two planetary gears to drive two internal gears to rotate, so that the two conveyor belts and the conveying components are in opposite directions, transporting scrap materials to the rear end, which facilitates the centralized collection and cleaning of waste materials.

[0014] Furthermore, the two external gears are respectively meshed with two planetary gears, and the two planetary gears are respectively meshed with two internal gears located at the rear.

[0015] The above technical solution facilitates the rotation of two external gears by two drive rods, which in turn drive two opposite planetary gears to rotate, and the two planetary gears drive two internal gears to rotate in the same direction.

[0016] Furthermore, a pressure plate structure and a rolling cutter structure are fixedly connected to the lower center of the adjacent end faces of the two main equipment units;

[0017] The above technical solution facilitates pressing the steel plate with a pressure plate structure and trimming the edge with a roll-cutting structure. This is a commonly used technical method in the existing technology and will not be elaborated on further here.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the double-sided shearing plate equipment is equipped with multiple springs, connecting seats and rubber pads on the conveying structure. The multiple springs push the multiple connecting seats to move outward of the roller, and the rubber pads increase the friction between the roller and the steel plate. During the conveying process, the steel plate is moved by the multiple rubber pads, and they are easy to replace after wear, thus preventing the problem of high replacement cost after the roller wears out.

[0020] 2. In this utility model, during the conveying process of the conveying component, the two drive rods at the rear drive the two external gears to rotate, the two external gears drive the two planetary gears to rotate in opposite directions, and the two planetary gears drive the two internal gears to rotate in the same direction, so that the two conveyor belts are opposite to the conveying direction of the conveying component, and the scraps are conveyed to the rear end, which facilitates the centralized collection and cleaning of waste materials.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 The present invention provides an embodiment of a feeding structure for a double-sided rolling shear, comprising two main equipment 1, which are arranged symmetrically in a horizontal arrangement, a support component 4 between the two main equipment 1, a base 3 located at the front end of the support component 4, and a conveying structure 2 on the upper surface of the base 3.

[0032] The conveying structure 2 includes multiple brackets 201 and multiple support frames 203. The brackets 201 are arranged in pairs, and the multiple sets of brackets 201 and support frames 203 are arranged in a crisscross pattern on the upper surface of the base 3. A servo motor 202 is fixedly connected inside each of the brackets 201 on one side. A roller 210 is fixedly connected to the output end of each servo motor 202. Multiple grooves 204 are provided on the outer wall of each roller 210. A spring 205 is fixedly connected to one end of each groove 204 near the axis of the roller 210. A connecting seat 20 is fixedly connected to the other end of each spring 205. 6. Each of the multiple connecting seats 206 has a rubber pad 207 on the other side. When multiple servo motors 202 are started, they drive multiple rollers 210 to rotate. The steel plate is placed on the outside of the multiple rubber pads 207. The multiple rubber pads 207 rotate with the multiple rollers 210, thereby moving the steel plate towards the front end of the main unit 1. During the conveying process, the steel plate squeezes the rubber pads 207, and the rubber pads 207 squeeze the connecting seats 206 and the springs 205. The tension of the springs 205 will push the connecting seats 206 and the rubber pads 207 towards the position of the steel plate, so as to provide support according to the uneven position of the bottom of the steel plate.

[0033] Multiple rubber pads 207 have mounting grooves 208 at the center of their end faces away from the multiple rollers 210. Each mounting groove 208 has a limiting screw 209 inside. The limiting screws 209 pass through the mounting grooves 208 and extend to one end face of the multiple rubber pads 207. Their ends are threaded to one end face of the multiple connecting seats 206. After the rubber pads 207 wear out, the limiting screws 209 are removed, and new rubber pads 207 are fixed by the limiting screws 209. This facilitates the replacement of the rubber pads 207 and prevents the high replacement cost caused by the rollers 210 directly contacting the steel plate and experiencing wear.

[0034] like Figure 1 , 2 As shown in Figure 3, multiple drive rods 7 are provided on one wall of each of the two main equipment units 1 on both sides of the support assembly 4. Two conveying assemblies 5 are provided between the multiple drive rods 7 and the support assembly 4. Two waste collection assemblies 6 are provided on the outside of the multiple drive rods 7. The two waste collection assemblies 6 include four bearings 601. The four bearings 601 are respectively sleeved on the outside of the four drive rods 7 at the front and rear ends, and the outer rings are respectively fixedly connected to one side wall of the two main equipment units 1. In use, the steel plate is conveyed to the front end through the support assembly 4 and the conveying assembly 5 between the two main equipment units 1.

[0035] like Figure 1 , 2 As shown in Figure 3, each of the four bearings 601 has a connecting ring 602 fixedly connected to the inner ring of its end face near the support assembly 4. Each of the four connecting rings 602 has an internal gear 603 fixedly connected inside. Each of the two drive rods 7 at the rear end has an external gear 604 fixedly sleeved on its outer side wall. Each of the two external gears 604 has a planetary gear 605 at its rear end. Each of the two conveying assemblies 5 has a conveyor belt 606 on one side. The two conveyor belts 606 are respectively sleeved on the outside of the four connecting rings 602. The two external gears 604 drive the two planetary gears 605 to rotate, and the two planetary gears 605 drive the two internal gears 603 to rotate. This makes the two conveyor belts 606 move in the opposite direction to the conveying direction of the conveying assembly 5, thus conveying the scrap material to the rear end, which is convenient for the centralized collection and cleaning of waste materials.

[0036] The two external gears 604 are respectively meshed with the two planetary gears 605, and the two planetary gears 605 are respectively meshed with the two internal gears 603 at the rear, so that the two drive rods 7 can drive the two external gears 604 to rotate, the two external gears 604 drive the two opposite planetary gears 605 to rotate, and the two planetary gears 605 drive the two internal gears 603 to rotate in the same direction.

[0037] Both main units 1 have a pressure plate structure and a rolling cutter structure fixedly connected at the lower center of their adjacent end faces. This allows the pressure plate structure to press down the steel plate and the rolling cutter structure to trim the edges. This is a commonly used technique in the prior art and will not be elaborated on here.

[0038] Working principle: During use, the steel plate is conveyed to the front end through the support component 4 and the conveying component 5 between the two main equipment 1. During the conveying process, the edge is trimmed by the pressure plate structure and the rolling cutting structure. During the trimming process, the scraps fall onto the conveyor belt 606. During the conveying process of the conveying component 5, the two drive rods 7 at the rear drive the two external gears 604 to rotate. The two external gears 604 drive the two opposite planetary gears 605 to rotate. The two planetary gears 605 drive the two internal gears 603 to rotate in the same direction, so that the two conveyor belts 606 and the conveying component 5 convey the scraps to the rear end, which facilitates the centralized collection and cleaning of waste materials.

[0039] After shearing, multiple servo motors 202 are activated, driving multiple rollers 210 to rotate. The steel plate is placed on the outside of multiple rubber pads 207. The rubber pads 207 rotate with the rollers 210, thus moving the steel plate towards the front end of the main unit 1. During the conveying process, the steel plate squeezes the rubber pads 207, and the rubber pads 207 squeeze the connecting seat 206 and the spring 205. The tension of the spring 205 pushes the connecting seat 206 and the rubber pads 207 towards the position of the steel plate, which facilitates support for uneven areas on the bottom of the steel plate. After the rubber pads 207 wear out, the limit screws 209 are removed, and new rubber pads 207 are fixed by the limit screws 209, which facilitates the replacement of the rubber pads 207 and prevents the high replacement cost caused by the rollers 210 directly contacting the steel plate and experiencing wear.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
