Description

Technical Field

[0001] This utility model relates to the field of die-casting equipment technology, and more specifically to a steel strip limiting component for an alloy lead pressing machine. Background Technology

[0002] Alloy lead strip casting machines, also known as belt continuous casting machines or belt die casting machines, are a special type of continuous steel casting equipment. Compared to traditional roll casting machines, their main difference lies in the fact that the billet is not transported and cooled through a series of support and guide rollers during solidification; instead, one or more circulating cooling steel belts are used. The working principle is as follows: high-temperature molten steel is first injected into a thin, wide, open crystallizer, where a preliminary solidified outer shell is formed; subsequently, the nascent billet is rapidly cooled by the continuously running cooling steel belt below, further completing the solidification process. Because the steel belt provides uniform and large-area contact cooling, this continuous casting method is particularly suitable for producing ultra-thin, ultra-wide strips or products with special shapes, such as thin slabs or irregularly shaped billets. Belt wheel continuous casting machines have advantages such as compact structure, small footprint, good billet thickness uniformity, and excellent surface quality.

[0003] Current lead tape pressing machines also have the following problems:

[0004] The steel die-casting belt on modern lead casting machines is ring-shaped. During operation, it enters between the crystallizing wheel and the upper pulley. After molten aluminum is injected into the casting groove between the die-casting belt and the crystallizing wheel, it is cooled by the crystallizing wheel and forms a long strip corresponding to the shape of the casting groove. This strip is then carried out with the die-casting belt. After one rotation, the die-casting belt re-enters between the crystallizing wheel and the upper pulley for a new round of die casting. However, after one rotation, the die-casting belt may shift due to its length or angle, causing the edge of the die-casting belt to shift into the compression area of ​​the crystallizing wheel and the upper pulley during die casting. This results in the die-casting belt being squeezed, leading to thinning or even cracking of the edge.

[0005] Chinese Utility Model Patent Application No. CN209021201U discloses a die-casting mechanism for continuous melting and casting of aluminum strip. The structure includes a rotatable die-casting strip, a crystallizing wheel, and a pressing box that presses the die-casting strip onto the crystallizing wheel. The crystallizing wheel and the pressing box are connected to a cooling water circulation mechanism. An annular die-casting groove is formed on the crystallizing wheel. The die-casting strip is pressed onto the crystallizing wheel so that molten aluminum can be received in the die-casting groove and cooled to form an aluminum strip corresponding to the thickness of the die-casting groove. However, this die-casting mechanism for continuous melting and casting of aluminum strip lacks a device to limit the inlet of the die-casting strip. This can cause the die-casting strip to travel an excessive distance, resulting in deviation when entering the space between the crystallizing wheel and the pressing box. This can lead to the die-casting strip being squeezed and damaged, thus increasing production costs.

[0006] Therefore, it is necessary to propose a steel strip limiting component for an alloy lead pressing machine to solve the above problems. Utility Model Content

The contact plate drives one end of the threaded cylinder to rotate axially through the second spline and can slide along the axial direction.

[0012] The rotating ring has first teeth at both ends and one side of the contact plate that cooperate with each other. The rotating ring drives the contact plate to rotate axially through the first teeth.

[0013] A spring is fixedly connected between the contact plate and the stop plate. The spring is sleeved on the second spline portion, and the spring pushes the contact plate to contact the rotating ring.

[0014] Preferably, the two ends of the drive block are symmetrically fixedly connected with annular blocks, and the side of the contact plate near the annular block is provided with a rolling groove that cooperates with the annular block. One end of the annular block located in the rolling groove is circumferentially arrayed with bullseye balls.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. This device has a limiting frame component on the upper pulley. By rotating the rotating rod on the limiting frame component, the distance between the two rollers can be adjusted to adapt to the width of the die-casting belt. This solves the problem that the edge of the die-casting belt will be squeezed and damaged by the crystallizing wheel and the upper pulley when the die-casting belt deviates. It also has the function of correcting the movement direction of the die-casting belt.

Detailed Implementation

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Please see Figure 1-8A steel strip limiting component for an alloy lead pressing machine includes a casting machine. The casting machine is a device for forging metal materials into long strips; this mature equipment will not be described in detail here. The casting machine includes an upper pulley 101, a crystallizing wheel 102, a lower pulley 103, and a die-casting belt 104. The die-casting belt 104 is sleeved on the outer walls of the crystallizing wheel 102 and the lower pulley 103, and is wound in a ring around the lower pulley 103 and the crystallizing wheel 102. The crystallizing wheel 102 is provided with a forming groove for the die-casting belt 104 to mate with. The feeding structure on the casting machine transports molten metal to the forming groove. Inside, rollers 106 limit the entry of the die-casting belt 104. The upper pulley 101 is rotatably connected to the crystallizing wheel 102 and squeezes the die-casting belt 104 on the outer wall of the crystallizing wheel 102. A limit frame 105 is provided on the upper pulley 101. The limit frame 105 and rollers 106 are arranged perpendicular to the die-casting belt 104. The limit frame 105 is fixed to the support frame 128 by bolts. The support frame 128 is provided with a strip groove 126, which can adjust the limit frame 105 laterally. The bottom of the limit frame 105 is provided with rollers 106 for limiting the die-casting belt 104.

[0035] refer to Figure 3 and Figure 4 The limiting frame 105 has a stop plate 107 and a bearing seat 108 fixedly connected inside. The bearing seat 108 supports the rotating ring 109 through a bearing. The stop plate 107 is used to lock the contact plate 115. The rotating ring 109 is connected inside the bearing seat 108 through a bearing. The limiting frame 105 has a rotating rod 110 inside. A driving block 111 is fixedly connected to the middle of the rotating rod 110. The rotating rod 110 drives the driving block 111 to move, enabling it to move and rotate axially. The outer ring surface of the driving block 111 and the inner ring surface of the rotating ring 109 are slidably connected by a first spline portion 112 that cooperates with each other. The tooth surfaces of 112 and the second spline 116 can be set to be inclined or square for connection. The drive block 111 drives the rotating ring 109 to rotate axially through the first spline 112. The outer walls of both ends of the rotating rod 110 are rotatably connected to symmetrical threaded cylinders 113. The threaded cylinders 113 are driven to rotate by the contact plate 115. The rotating rod 110 rotates inside the threaded cylinder 113. The moving block 114 is driven to move by the rotation of the threaded cylinder 113. The moving block 114 drives the roller 106 at the bottom to move. The bottom of the moving block 114 is rotatably connected to the roller 106.

[0036] refer to Figure 4 and Figure 6A contact plate 115 is provided on the outer wall of one end of the threaded cylinder 113 near the drive block 111. The contact plate 115 is used to connect the threaded cylinder 113 and the rotating ring 109. The contact plate 115 can move axially at one end of the threaded cylinder 113. A spring 118 on one side pushes the contact plate 115 to contact the rotating ring 109. A second spline portion 116 is provided at the position where the contact plate 115 contacts the threaded cylinder 113. The contact plate 115 drives one end of the threaded cylinder 113 to rotate axially through the second spline portion 116, and can slide along the axial direction.

[0037] refer to Figure 6 and Figure 7 The rotating ring 109 has first teeth 117 that cooperate with each other at both ends and one side of the contact plate 115. The rotating ring 109 drives the contact plate 115 to rotate through the first teeth 117. When the contact plate 115 is separated from the rotating ring 109, it will contact the stop plate 107 on the other side and will not rotate with the rotating ring 109. The rotating ring 109 drives the contact plate 115 to rotate axially through the first teeth 117.

[0038] refer to Figure 6 A spring 118 is fixedly connected between the contact plate 115 and the stop plate 107. The spring 118 pushes the contact plate 115 toward the rotating ring 109. When the rotating rod 110 is manually pushed or pulled, the corresponding spring 118 will be compressed. The spring 118 is sleeved on the second spline part 116. The spring 118 pushes the contact plate 115 to contact the rotating ring 109.

[0039] Specifically, refer to Figure 5 and Figure 6 The two ends of the drive block 111 are symmetrically fixed with annular blocks 119. When the drive block 111 moves, it will drive the annular blocks 119 to move. The drive block 111 pushes the contact plate 115 to separate from the rotating ring 109 through the annular blocks 119. Then the contact plate 115 contacts the stop plate 107. Even when the annular block 119 rotates, it will rotate in the rolling groove 120 through the bullseye balls 121 and will not directly rub against the contact plate 115. The side of the contact plate 115 near the annular block 119 is provided with a rolling groove 120 that cooperates with the annular block 119. The annular block 119 is surrounded by a circumferential array of bullseye balls 121 at one end in the rolling groove 120.

[0040] Specifically, refer to Figure 6The side of the contact plate 115 opposite to the stop plate 107 is provided with a second tooth 122 that can cooperate with each other. The stop plate 107 locks the contact plate 115 through the second tooth 122 to prevent it from rotating. When the stop plate 107 is in contact with the contact plate 115 through the second tooth 122, it can fix the contact plate 115. The second tooth 122 is located on the outside of the spring 118.

[0041] Specifically, refer to Figure 4 The top of the limit frame 105 is provided with a slide rail 123. When the moving block 114 moves, the top slider 124 moves along the slide rail 123 to improve the stability during movement. The top of the moving block 114 is fixedly connected to a slider 124 that is slidably connected to the slide rail 123.

[0042] Specifically, refer to Figures 3 to 6 Limiting brackets 105 extend from both ends of the rotating rod 110. The middle part of the rotating rod 110 is connected to the drive block 111, and the two ends are connected to the rotating handles 125. The rotating handles 125 are provided with hexagonal holes, which can be rotated by tools. The rotating rod 110 is provided with rotating handles 125 at both ends.

[0043] Specifically, refer to Figure 2 and Figure 8 A support frame 128 is fixedly connected to the upper pulley 101. One end of the support frame 128 is fixed to the upper pulley 101, and the other end is used for the installation of the limit frame 105. A strip groove 126 is provided on the support frame 128. The limit frame 105 is installed in the strip groove 126 by bolts. The support frame 128 and the limit frame 105 are connected by bolts. The strip groove 126 is provided on the support frame 128, and the strip groove 126 can be used for the lateral adjustment of the limit frame 105.

[0044] Specifically, refer to Figure 1 and Figure 2 A baffle 127 is provided on the top of the upper pulley 101. The baffle 127 can protect the upper pulley 101 and prevent foreign objects from entering. One end of the baffle 127 is fixedly connected to the support frame 128, and the other end of the baffle 127 is fixedly connected to the casting machine.

[0045] In this embodiment, the limiting frame 105 is mounted on the upper pulley 101 via the support frame 128. When the die-casting belt 104 enters the working area between the upper pulley 101 and the crystallizing wheel 102, the rollers 106 at the bottom of the limiting frame 105 can correct the die-casting belt 104 and prevent it from shifting due to length or angle. The top of the support frame 128 can support the baffle 127, which can protect the upper pulley 101, prevent foreign objects from entering, and prevent personnel injury.

[0046] When it is necessary to adjust the distance between the two rollers 106, the rotating handle 125 causes the rotating rod 110 to rotate. The rotating rod 110 drives the driving block 111 in the middle to rotate. The driving block 111 drives the rotating ring 109 on the outer wall to rotate through the first spline part 112. The rotating ring 109 drives the contact plates 115 on both sides to rotate through the first tooth part 117. The contact plates 115 then drive the threaded cylinder 113 to rotate through the second spline part 116, thereby causing the rollers 106 on both sides to move towards each other, thereby adjusting the distance between the two rollers 106.

[0047] The roller 106 on one side can be adjusted by pushing or pulling the rotating rod 110. For example, if the roller 106 on the left side needs adjustment, the rotating rod 110 is pushed to the right by the rotating handle 125. The rotating rod 110 drives the drive block 111 to move to the right. At this time, the annular block 119 on one side of the drive block 111 pushes the contact plate 115 to the right. The contact plate 115 moves along the second spline portion 116, and the spring 118 on one side is compressed. The contact plate 115 on the right side disengages from the rotating ring 109 at the top and simultaneously contacts the stop plate 107 on the other side. The stop plate 107 contacts the contact plate through the second tooth portion 122. 115 acts as a lock to prevent the contact plate 115 from rotating. At this time, rotating the rotating rod 110 causes the rotating ring 109 to rotate, which in turn causes the left contact plate 115 to rotate. Meanwhile, the right contact plate 115 disengages from the rotating ring 109 and does not rotate. This allows for individual control of the left roller 106. Similarly, when adjusting the right roller 106, the rotating rod 110 is pushed to the left and rotated. When a large-scale movement of the limiting frame 105 is required, the support frame 128 has a slot 126 that allows for a large-scale lateral movement of the limiting frame 105.

[0048] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
