Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a material strip winding structure, particularly a waste material winding device and a high-speed stamping equipment. Background Technology

[0002] A punch press is a stamping press. In national production, stamping technology is becoming increasingly widely used because it saves materials and energy, has high production efficiency, requires less technical skill from operators, and can produce products that cannot be achieved by machining through the application of various molds.

[0003] When processing strip material, some large punch presses punch the workpiece off the strip material. The scrap material is then wound up by a winding mechanism controlled by a separate motor. The winding mechanism cannot effectively control the winding of the scrap material. If the winding speed is too fast, the scrap material will pull on the material, which will affect the punch press from the strip material to punch the workpiece.

[0004] For example, Chinese patent document 202311209164.0 discloses an automatic rewinding machine for punch press scrap strips capable of detecting stamping defects. The punch press includes a machine body and a machine body drive system. The automatic rewinding machine for punch press scrap strips includes a mounting frame, a drum, and a drum drive system. The mounting frame is equipped with a scrap strip tightening device. The scrap strip tightening device includes a clamping mechanism for clamping the scrap strip and an adjusting mechanism for adjusting the clamping force of the clamping mechanism. The mounting frame is also equipped with a defective product early warning and shutdown device. The defective product early warning and shutdown device includes a trigger switch and a triggering mechanism for controlling the trigger switch.

[0005] In the above technical solution, the waste strip generated after stamping is collected by winding the material into a roll. However, the winding machine directly winds the waste strip onto the reel, which causes the inner ring of the waste strip to be tightly pressed against the reel, resulting in a large friction force and making it difficult to unload the material from the reel. In addition, there is no automatic sensing of the length of the waste strip, so it cannot automatically coordinate with the winding operation. The waste strip is prone to getting stuck due to winding too slowly, or it will break due to winding too fast. Utility Model Content

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] Example 1

[0033] like Figures 1 to 3 As shown, this waste material winding device includes a fixed frame 1, a winding motor 2 fixedly mounted on the fixed frame 1, a rotating rod 4 driven by the winding motor 2, a fixed baffle and a detachable baffle sleeved on the rotating rod 4, a winding space formed between the fixed baffle and the detachable baffle, a pair of winding rods 9 fixedly mounted on the fixed baffle, the winding rods 9 extending from the fixed baffle through the winding space to the detachable baffle, and a groove 9a recessed along the axial direction on the surface of the winding rods 9, the grooves 9a of the pair of winding rods 9 being arranged opposite each other.

[0034] like Figure 1 As shown, the fixed frame 1 includes a base in the shape of a rectangular plate, a vertical rod is set on the base, the vertical rod is fixed perpendicular to the center of the base, the winding motor 2 is fixed on the vertical rod, and a reducer 3 is fixedly connected to the output shaft of the winding motor 2. The output shaft of the reducer 3 is coaxially connected to the rotating rod 4 through a coupling.

[0035] The coil motor 2 is specifically a servo motor. The rotating rod 4 is perpendicular to the vertical rod and parallel to the base, forming a horizontal configuration. Starting the coil motor 2 drives the reducer 3 to operate, which in turn drives the rotating rod 4 to rotate synchronously via the coupling, thus performing the coiling operation.

[0036] One end of the rotating rod 4 is the connecting end, and the other end is suspended to form a free end. First, the fixed baffle is sleeved on the rotating rod 4 and close to the connecting end. Then, the disassembly baffle is sleeved on the rotating rod 4 and close to the free end, so that the rotating rod 4 part between the fixed baffle and the disassembly baffle forms the width of the roll.

[0037] like Figure 1 and 2 As shown, the fixed baffle includes a cross-shaped body with four centrally symmetrical limiting rods 5. Adjacent limiting rods 5 form a 90° angle. A through hole is opened in the center of the cross-shaped body, through which a rotating rod 4 passes. The cross-shaped body is fixed to the rotating rod 4 by screws. The cross-shaped body acts as a winding limiter on one side of the waste roll, facilitating the neat winding of the waste strip.

[0038] The limiting rod 5 has a guide groove along its length. The outer end of the guide groove is an open opening. The adjusting rod 6 is slidably connected inside the guide groove. The extended end of the adjusting rod 6 has a smooth end. The limiting rod 5 connects to the guide groove and forms an adjusting groove 5a. At least one screw 7 is fixed on the adjusting rod 6. The screw 7 passes through the adjusting groove 5a to form a guide connection. A nut 8 is sleeved on the protruding end of the screw 7 to form a locking fixation.

[0039] Loosen nut 8 and adjust rod 6 to slide along guide groove 1, simultaneously moving screw 7 along adjustment groove 5a. Once the adjusting rod 6 reaches the appropriate extension length, retighten nut 8 to lock the adjusting rod 6 in place. By adjusting the extension length of the four adjusting rods 6, the overall size of the cross-shaped structure can be adjusted to accommodate waste rolls of different radii.

[0040] One end of the winding rod 9 is fixed to the inner end of the adjusting rod 6. The end of the winding rod 9 facing the disassembly and assembly stop is the snap-fit ​​end. The snap-fit ​​groove 9a extends along the length of the winding rod 9 to the snap-fit ​​end to form a snap-fit ​​opening that connects to the outside. The snap-fit ​​groove 9a is a long groove. The waste material is an aluminum strip. One end of the waste material strip is inserted into the snap-fit ​​groove 9a from the snap-fit ​​opening to form a hook, thereby fixing the end of the waste material.

[0041] like Figure 1 and 3 As shown, the disassembly and assembly of the baffle includes a T-shaped frame body. The T-shaped frame body is composed of three limiting rods 10 arranged in a T-shape. A through hole 2 is opened in the center of the T-shaped frame body. A locking ring 11 is coaxially arranged through the through hole 2. The rotating rod 4 passes through the locking ring 11. A locking bolt 12 passes through the locking ring 11 to form a threaded connection. The inner end of the locking bolt 12 abuts against the rotating rod 4 to form a locking and fixing.

[0042] Loosen the locking bolt 12 and the locking ring 11, remove the T-shaped frame from the rotating rod 4, and then pull out the waste material roll wound on the middle of the rotating rod 4 axially. After removing the material, put the T-shaped frame back onto the free end of the rotating rod 4, retighten the locking bolt 12, and fix the locking ring 11.

[0043] The limiting rod 10 has a guide groove 2 along its length. The outer end of the guide groove 2 is an open opening. The adjusting rod 13 slides through the guide groove 2. The extended end of the adjusting rod 13 has a smooth end. The limiting rod 10 connects to the guide groove 2 to form an adjusting groove 10a. At least one screw 14 is fixed on the adjusting rod 13. The screw 14 passes through the adjusting groove 10a to form a guide connection. The protruding end of the screw 14 is fitted with a nut 15 to form a locking and fixing.

[0044] Loosen nut 15 and adjust rod 13 to slide along guide groove 2, simultaneously moving screw 14 along adjustment groove 10a. Once the adjustment rod 13 has reached the appropriate extension length, retighten nut 15 to lock it in place. By adjusting the extension length of the three adjustment rods 13, the overall size of the T-shaped frame can be adjusted to accommodate waste rolls of different radii.

[0045] Example 2

[0046] Based on Embodiment 1, the difference in this embodiment is:

[0047] like Figure 4 As shown, the waste winding device also includes a control frame 16, which includes a base 2 in the shape of a rectangular plate, and a vertical rod 2 is installed on the base 2, which is fixed perpendicular to the center of the base 2.

[0048] The second vertical rod is slidably fitted with a second locking ring 17, and a second locking bolt 18 is threaded through the second locking ring 17 to form a threaded connection. The inner end of the second locking bolt 18 abuts against the second vertical rod to form a locking fixation. A support rod 19 is fixedly connected to the second locking ring 17, and an upper detection rod 20 and a lower detection rod 21 are connected to the support rod 19. A detection space is formed between the upper detection rod 20 and the lower detection rod 21.

[0049] Loosening the second locking bolt 18 allows the second locking ring 17 to move up and down along the second vertical rod, thereby adjusting and controlling the height. Tightening the second locking bolt 18 again fixes the second locking ring 17 in a fixed state through friction. The support rod 19 is vertically set, with the upper end connected to the upper detection rod 20 and the lower end connected to the lower detection rod 21. The upper detection rod 20 and the lower detection rod 21 are set horizontally, and both have pressure sensors. The waste material strip is passed through the detection space, i.e., placed between the upper detection rod 20 and the lower detection rod 21. When the waste material strip contacts the pressure sensor of the lower detection rod 21, it indicates that the waste material strip is too long, and the winding motor 2 is started to wind the material; when the waste material strip contacts the pressure sensor of the upper detection rod 20, it indicates that the waste material strip is too short, and the winding motor 2 is turned off to stop winding the material.

[0050] The operation method of this waste rewinding device is as follows:

[0051] 1. Pass the waste material strip through the detection space, insert one end of the waste material strip into the slot 9a from the snap-fit ​​slot to form a hook, and realize the connection between the waste material strip and the rotating rod 4.

[0052] 2. When the waste material strip comes into contact with the pressure sensor of the lower detection rod 21, the winding motor 2 is started to drive the reducer 3 to run. The reducer 3 is driven to rotate synchronously through the coupling. Then, the fixed baffle, winding rod 9 and disassembly baffle on the rotating rod 4 rotate synchronously, winding the waste material strip around the outer circumference of the two winding rods 9. At the same time, the fixed baffle and disassembly baffle limit and stop the waste material tray on both sides respectively.

[0053] 3. When the waste material strip comes into contact with the pressure sensor of the upper detection rod 20, the winding motor 2 will be automatically shut off and the winding will be stopped.

[0054] 4. Loosen the locking bolt 12 and the locking ring 11, remove the T-shaped frame from the rotating rod 4, and then pull out the waste material tray wrapped around the middle of the rotating rod 4 axially. After removing the material, put the T-shaped frame back onto the free end of the rotating rod 4, tighten the locking bolt 12 again, and fix the locking ring 11.
