Description

Technical Field

[0001] The utility model relates to the technical field of annular steel forming devices, in particular to a device for low-margin forming of annular steel strips. Background Art

[0002] In the field of steel strip processing, the forming process of annular steel strips is crucial. For traditional annular steel strip forming, raw materials need to be selected first, followed by leveling and cutting. During cutting, welding margins need to be reserved. After that, the steel strip is rolled into an arc shape and welded at the specified size and position. In the process of punching the base material from the strip and forming it into a circle in this traditional annular steel strip forming process, in order to feed the strip, the base material cutting needs to reserve strip margins to switch workstations, which leads to the generation of a large amount of waste. This not only increases the material cost but also reduces the material utilization rate. On the other hand, when some forming devices process the steel strip, the degree of deformation at one time is too large, resulting in easy damage to the steel strip. Therefore, traditional annular steel strip forming equipment is prone to waste raw materials during steel strip processing, is inconvenient for cutting, and is easy to damage the steel strip, and cannot meet the needs of those skilled in the art. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide a device for low-margin forming of annular steel strips to solve the problems of large reserved strip margins, high costs, and inconvenient cutting mentioned in the above background art.

[0004] To achieve the above purpose, the present utility model provides the following technical solution: A device for low-margin forming of annular steel strips includes a roller and a frame for supporting the roller. The roller is rotatably connected to the frame. A first driver for driving the roller to rotate is arranged on the frame. A chamber is opened in the middle of the roller. A processing device is arranged in the chamber. A long groove for processing the steel strip is arranged on the roller. The processing device passes through the long groove to contact the steel strip and processes the head and tail connection of the steel strip by moving along the length direction of the long groove.

[0005] As a further improvement of the present utility model, the processing device includes a lead screw, a nut, and a second driver for driving the lead screw to rotate. A welding head is arranged on the nut. The lead screw is arranged corresponding to the length direction of the long groove. A limiting groove is arranged along the length direction of the lead screw in the chamber. A limiting slide bar is arranged between the nut and the limiting groove. One end of the limiting slide bar is fixedly connected to the nut, and the other end is slidably matched with the limiting groove. The second driver drives the lead screw to rotate to drive the nut to slide along the length direction of the lead screw.

[0006] As a further improvement of the present utility model, the processing device further includes a cutting head arranged on the frame. The cutting head is arranged corresponding to the side opposite to the rotation direction of the roller with respect to the welding head.

[0007] As a further improvement of the present invention, a gap is provided between the cutting head and the welding head to allow the steel plate to have a margin after cutting.

[0008] As a further improvement of the present invention, a sensor for sensing the middle position of the steel strip is provided at a mirror image position of the roller corresponding to the long groove with the axis of the roller as the dividing line.

[0009] As a further improvement of the present invention, the width of the long groove is greater than the width of the gap.

[0016] An embodiment of the present invention is shown in the figure. In order to achieve the above-mentioned purpose, the present invention provides a low-allowance forming device for annular steel strip, including a roller 1 and a frame 2 for supporting the roller 1, the roller 1 is rotatably connected to the frame 2, the frame 2 is provided with a first driver 3 for driving the roller 1 to rotate, a chamber is opened in the middle of the roller 1, a processing device is provided in the chamber, a long groove for processing the steel strip is provided on the roller 1, the processing device contacts the steel strip through the long groove and processes the head and tail connection of the steel strip by moving along the length direction of the long groove.

[0017] When implementing this welding head solution, the frame 2 is first firmly installed on the work platform, and the roller 1 is rotationally connected to the frame 2 through a rotating connector, which can be achieved by setting gears and motors to rotate, ensuring that the roller 1 can rotate flexibly; the first driver 3 is installed on the frame 2 and connected to the roller 1 through a transmission mechanism such as a belt, gears, etc., to drive the roller 1 to rotate; the processing device is placed in the cavity in the middle of the roller 1, and at the same time ensure that the processing device corresponds to the long groove on the roller 1, so that the processing device can pass through the long groove and extend out of the outer surface of the roller 1 or be flush with the surface of the roller 1. During use, the annular steel belt is sleeved on the outside of the roller 1, and the first driver 3 is started to drive the roller 1 to rotate and move the steel belt. At this time, technical personnel in this field need to record the initial contact position of the steel belt and the roller 1. When the roller 1 rotates one circle and returns to the initial position of rotation, the steel belt also rotates one circle. If cutting is performed at this time, the steel belt can be connected end to end to form an annular steel belt. At this time, the processing device is started, and the processing device moves along the length direction of the long groove, and welding and other processing operations are performed on the connection between the end and the tail of the steel belt. Through the coordinated movement of the rotation of the roller 1 and the processing device, it is not easy for the steel belt to have too much margin when connecting, so that low margin forming processing of the annular steel belt is realized. The whole process is convenient and efficient. This scheme preferably uses a motor to drive the processing device to move. In other schemes, technical personnel in this field can also use manual operation of the processing device to move to perform welding, cutting and other processing operations on the connection of the steel belt.

[0018] The welding head is a specific embodiment of the improvement, and the processing device includes a screw, a nut and a second driver 4 for driving the screw to rotate. The nut is provided with a welding head, and the screw is arranged in the length direction of the long slot. A limiting slot is provided in the chamber along the length direction of the screw, and a limiting slide is provided between the nut and the limiting slot. One end of the limiting slide is fixedly connected to the nut, and the other end is slidably matched with the limiting slot. The second driver 4 drives the screw to rotate to drive the nut to slide along the length direction of the screw; the roller 1 is provided with a sensor for sensing the middle position of the steel strip at a mirror position corresponding to the long slot with the axis of the roller 1 as the dividing line.

[0019] When implementing this solution for the welding head, the rotation speed and torque of the second driver 4 are first matched and calibrated to ensure that the moving speed of the welding head is coordinated to avoid welding dislocation or quality defects caused by speed mismatch. When the second driver 4 is working, the second driver 4 rotates the screw so that the nut on the screw can move along the thread direction of the screw, that is, the length direction. Since this solution adopts the method of setting the welding head on the nut, the movement of the nut can drive the welding head to move, and the nut is restricted by the limiting groove to avoid the nut from rotating synchronously with the screw when the screw rotates. The limiting groove in this solution mainly applies its limiting function. In other solutions, limiting structures such as limiting convex edges can also be used to limit the limiting slide rod on the nut, thereby limiting the nut. The induction in this solution The sensor can be used to sense the position where the steel belt starts to rotate and the position where it rotates to. In this solution, the sensor is set at the mirror position of the corresponding long groove with the axis of roller 1 as the dividing line. For example, if the long groove is set at the lower side of roller 1, the sensor should be set at the position after rotating 180° along the roller 1 with the long groove as the starting point, that is, the opposite side of the long groove with roller 1 as the axis. When the sensor senses the middle position of the steel belt, it only needs to rotate roller 1 180° to complete the connection between the end of the circular steel belt. At this time, if it is necessary to leave a margin at the connection between the end and the beginning, the roller 1 can be manually rotated slightly again to form a margin, and finally welding and cutting are performed to complete the production of the circular roller 1. The installation position of the sensor in this solution can avoid the sensor from incorrectly sensing the steel belt.

[0020] As a specific embodiment of the improvement, the welding head, the processing device also includes a cutting head 5 arranged on the frame 2, and the cutting head 5 is arranged on the side opposite to the rotation direction of the roller 1 corresponding to the welding head; a gap is provided between the cutting head 5 and the welding head for allowing the steel plate to have a margin after cutting; the width of the long groove is greater than the width of the gap.

[0021] When implementing the welding head scheme, a cutting head 5 is set on the frame 2. In this scheme, the position of the cutting head 5 needs to be set corresponding to one side of the welding head, and is on the side opposite to the rotation direction of the roller 1. The side of the welding head in this embodiment does not refer to the side that needs to be in the same plane as the welding head. Since the welding head is installed on the nut, the cutting head 5 in this scheme needs to cut the annular steel strip after welding. Therefore, the welding head is preferably set on the frame 2, and the cutting head 5 can be moved to cut the steel coil by motor drive or manual movement. If the roller 1 rotates clockwise, the welding head is preferably set on the left side of the cutting head 5 in this scheme, that is, when the roller 1 rotates clockwise, the starting end of the steel coil will first meet the cutting head 5 and then meet the welding head. At this time, the welding head first welds the starting end of the steel coil to the steel coil, and then cuts it at the position where the margin is set; if the roller 1 rotates counterclockwise, the welding head is set on the right side of the cutting head 5.

[0022] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
