Description

Technical Field

[0001] The utility model relates to a steel strip calendering processing equipment, in particular to a positioning device for steel strip calendering processing. Background Art

[0002] Calendering refers to the process of pressing a flat blank of a certain shape into an open hollow part through a die under the pressure of a punch. Calendering actually refers to forging (forming in the solid state), which can only forge steel and ultimately change the physical state of steel. The steel strip is calendered by a calender. Before the steel strip enters between the rollers of the calender, its position needs to be limited to ensure that the steel strip can be kept in the middle between the two rollers during the calendering process to prevent the steel strip from running off and producing an uneven calendering effect. The positioning device for steel strip calendering, which is currently widely used, can only limit the position of the steel strip to ensure that the steel strip does not tilt during transportation, but it cannot always keep the steel strip in the middle between the two rollers, which still leads to the problem of uneven calendering.

DETAILED DESCRIPTION

[0037] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0038] like Figure 1-Figure 4 As shown, the utility model proposes a positioning device for steel strip calendering processing, which mainly includes a frame 1, a conveying component 2, a correction push plate 8, a guide component 3, a pressure roller 10, a sliding rod 5, a connecting rod 6, a first clamping component 7 and a second clamping component 11.

[0039] Among them, the correction push plate 8, the guide assembly 3 and the pressure roller 10 are sequentially arranged on the top of the frame 1 along the conveying direction of the conveying assembly 2. There are two correction push plates 8, which are symmetrically arranged on both sides of the feeding end of the conveying assembly 2 and are slidably arranged on the top of the frame 1 through the cylinder 9. They are used to roughly correct the end of each steel belt before it enters the guide assembly 3 after each steel belt enters the feeding end of the conveying assembly 2, so as to avoid the problem that the steel belt is too skewed and cannot enter the guide assembly 3 well. A rubber pad is fixedly arranged on the side of the correction push plate 8 away from the cylinder 9, which is conducive to preventing the correction push plate 8 from damaging the steel belt when pushing it, and can also increase the friction between the steel belt and the steel belt to avoid slipping.

[0040] The conveying assembly 2 is arranged on the frame 1, and the conveying assembly 2 includes a plurality of conveying rollers 21 arranged in an array, and the plurality of conveying rollers 21 are all rotatably arranged on the frame 1 through the transmission assembly 13. The conveying assembly includes a plurality of sprocket wheels 131, a chain 132, a driving pulley 133, a driven pulley 134, a transmission belt 135 and a motor 136. The plurality of sprocket wheels 131 are respectively fixedly sleeved on the ends of the plurality of conveying rollers 21, the chain 132 is sleeved on the outer sides of the plurality of sprocket wheels 131 and cooperates with the plurality of sprocket wheels 131, a driven pulley 134 is fixedly sleeved on the end of one of the conveying rollers 21, a driving pulley 133 is rotatably arranged on the frame 1, a transmission belt 135 is transmission-sleeved on the driving pulley 133 and the driven pulley 134, a motor 136 is fixedly arranged on the frame 1, and an output shaft of the motor 136 is fixedly connected to the driving pulley 133. The specific operating steps of the conveying component 2 are as follows: the motor 136 is started to drive the active pulley 133 to rotate, the active pulley 133 drives the driven pulley 134 to rotate through the transmission belt 135, the driven pulley 134 drives one of the transmission rollers to rotate, the transmission roller drives the sprocket 131 thereon to rotate, the sprocket 131 drives multiple sprockets 131 to rotate synchronously through the chain 132, thereby driving multiple transmission rollers to rotate synchronously to realize the conveying of the steel belt.

[0041] There are multiple guide assemblies 3, which are arranged along the conveying direction of the conveying assembly 2. Each guide assembly 3 includes two guide rollers 31. The two guide rollers 31 are symmetrically arranged on both sides of the conveying assembly 2 and are slidably arranged on the top of the frame 1 through the shaft rod 4. Specifically, the guide roller 31 is rotatably arranged on the top of the shaft rod 4, which is beneficial for the guide roller 31 to be positioned while being conveyed forward with the steel belt to reduce friction. A plurality of second slide grooves 12 are opened on the frame 1. The length direction of the second slide grooves 12 is perpendicular to the conveying direction of the conveying assembly 2. Each shaft rod 4 is slidably arranged in a second slide groove 12. The setting of the second slide groove 12 is beneficial for limiting the sliding direction of the shaft rod 4.

[0042] The sliding rod 5 is slidably arranged on the frame 1 along the conveying direction of the conveying assembly 2, and is located in the middle of the multiple conveying rollers 21. There are multiple connecting rods 6, which correspond to the shaft rod 4 one by one. One end of the connecting rod 6 is rotatably connected to the shaft rod 4, and the other end is rotatably connected to the sliding rod 5. The coordinated arrangement of the sliding rod 5 and the multiple connecting rods 6 is conducive to realizing the linkage of the multiple guide rollers 31, and the guide rollers 31 on both sides of the conveying roller 21 always slide away from or gather together with the central axis of the sliding rod 5 as the symmetry axis, so as to limit the steel plate while ensuring that the central axis of the steel strip is always in the same vertical plane as the central axis of the sliding rod 5, thereby ensuring the subsequent rolling effect.

[0043] The first clamping assembly 7 is composed of several groups, all of which are arranged on the frame 1, and are used to push the guide rollers 31 to press against the steel belt. As shown in the figure, in this embodiment, the first clamping assembly 7 is composed of four groups, which are respectively located at the two guide rollers 31 near the feeding end of the conveying assembly 2 and the two guide rollers 31 near the discharging end of the conveying assembly 2. Specifically, the first clamping assembly 7 includes a mounting block 71, a first guide rod 72 and a first spring 73. The mounting block 71 is fixedly arranged on the shaft 4, one end of the first guide rod 72 is fixedly connected to the mounting block 71, and the other end is slidably penetrated on the frame 1, and the first spring 73 is sleeved on the first guide rod 72, and one end abuts against the mounting block 71, and the other end abuts against the frame 1.

[0044] The pressing roller 10 is arranged at the discharge end of the conveying assembly 2, and a gap for the steel strip to pass through is arranged between the pressing roller 10 and the conveying assembly 2. The arrangement of the pressing roller 10 can limit the position of the steel strip in the vertical direction before the steel strip enters the calendering process to prevent the steel strip from deflecting.

[0045] There are two second clamping assemblies 11, which are connected to both ends of the pressure roller 10 respectively. Each second clamping assembly 11 includes a mounting seat 111, a slider 112, a second guide rod 113 and a second spring 114. The mounting seat 111 is fixedly arranged on the top of the frame 1. A first slide groove 115 is vertically arranged along the length direction in the middle of the mounting seat 111. The slider 112 is vertically slidably arranged in the first slide groove 115. The pressure roller 10 is rotatably arranged on the slider 112. The lower end of the second guide rod 113 is fixedly arranged on the slider 112, and the upper end is lifted and passed through the mounting seat 111. The second spring 114 is sleeved on the second guide rod 113, and one end abuts against the slider 112, and the other end abuts against the inner wall of the first slide groove 115. The arrangement of the second clamping assembly 11 is conducive to automatically clamping the pressure roller 10 on the top of the steel belt.

[0046] During use of this embodiment, the motor 136 is first started to drive the multiple conveying rollers 21 to rotate, and one end of the steel belt is placed at the feed end of the conveying assembly 2 through a conveying device or manually, and then the two cylinders 9 are started to drive the correction push plate 8 to slide in the direction close to the steel belt and push the two side surfaces of the end of the steel belt to roughly correct the position of the steel belt. After that, the cylinder 9 contracts, driving the correction push plate 8 to reset, and then the steel belt is conveyed forward under the action of the conveying roller 21, so that the steel belt gradually enters between the multiple guide rollers 31, and the multiple guide rollers 31 are pressed against the steel belt through the first spring 73 and rotated as the steel belt is conveyed. When the end of the steel belt is conveyed to the pressure roller 10, the steel belt passes between the pressure roller 10 and the conveying assembly 2, and the pressure roller 10 presses the top surface of the steel belt under the pressure of the second spring 114 and rotates as the steel belt is conveyed, thereby realizing the positioning of the steel belt from all directions.

[0047] The sliding setting of the guide roller 31 can be applicable to the positioning of steel plates of different widths (the length of the second slide groove 12 is the floating limit between the maximum width and the minimum width of the steel plate), and the guide roller 31 is used to press the steel plates of the above-mentioned widths through the first clamping component 7; the lifting setting of the pressing roller 10 can be applicable to the positioning of steel plates of different heights (the length of the first slide groove 115 is the floating limit between the maximum height and the minimum height of the steel plate), and the pressing roller 10 is used to press the steel plates of the above-mentioned heights through the second clamping component 11, which is highly practical.

[0048] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
