Description

Technical Field

[0001] The present invention relates to the technical field of calender positioning and installation, and specifically to a positioning tooling for manufacturing the pressing frame component of an ultra-thin calender. Background Art

[0002] The calender in a glass production line is located between the melting furnace and the annealing furnace. Its main function is to calender the molten glass liquid into a glass ribbon of a certain thickness, and convey the glass ribbon into the annealing furnace for annealing through the air system between the rollers. It belongs to the forming part of calendered glass. The production of calendered glass is achieved by pressing between the upper roller and the lower roller. The fixing of the upper roller and the stability of the downward pressing action are controlled by applying adjustable pressure through the pressure rod and the pressing frame. As the demand for calendered glass from each manufacturer is increasing. The thickness of glass products has been gradually reduced from 3.2 mm to 1.5 mm, which is currently the world's most advanced level. As the thickness of the glass decreases, the required pressure increases accordingly. The accuracy requirements for the pressing frame are also getting higher and higher.

[0003] Refer to Figure 1 and Figure 2 , the pressing frame transmits pressure to the upper roller 7' of the calender through the positioning pressure rod 6', and the maximum pressure can reach 5500 kg; and the position of the pressing frame is directly above the glass liquid 8', and the ambient temperature is as high as more than 90 degrees. Therefore, when the pressing frame applies pressure, the position of the stress point must be correct. Even a slight deviation of the basic pressing frame will cause distortion of the positioning pressure rod 6', the pressure lever support frame 2', the pressure lever 5', the screw jack support frame 3' and the screw jack 4', resulting in the inability to control the quality of the glass during production due to inaccurate pressure; when the calender and the pressing frame made by traditional technology are used for the first time, when the pressure increases to 1500 kg, the positioning pressure rod 6' tilts at an angle, the pressure cannot continue to increase, and the feedback signal of the pressure sensor has an obvious error, which cannot ensure the stable quality of the product. After analyzing and detecting the reasons, the several main load-bearing stress points of the pressing frame are not on the same center line during production. When the screw jack 4' applies pressure, the whole pressing frame is distorted, resulting in the non-verticality of the positioning pressure rod 6', so the stable quality cannot be ensured; thus, it can be seen that during the manufacturing process of the pressing frame, there are very high requirements for parallelism, perpendicularity, position accuracy, and structural stiffness; due to the 1560 mm center distance and 573.8 mm height difference between the two main stress points of the pressing frame; it is difficult to position and measure during production, and it is difficult to ensure the accuracy. There is a large difference in accuracy when manufacturing multiple products in the same batch. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a positioning tooling for manufacturing the pressing frame component of an ultra-thin calender with accurate positioning.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A positioning tooling for manufacturing the pressing frame component of an ultra-thin calender, including a tooling base, two vertical rods with different lengths, a cross bar connected between the tops of the two vertical rods, a plumb bob, and a positioning adjustment device for driving the positioning movement of the plumb bob; the two vertical rods are respectively fixed at both ends of the tooling base by bolts; the cross bar is erected between the tops of the two vertical rods; the positioning adjustment device is fixedly installed on the cross bar; the plumb bob is slidably fitted on the positioning adjustment device through a suspension line; the pressing frame base is placed on the tooling base; pressure lever support frames and screw jack support frames are respectively installed at both ends of the top of the pressing frame base; the ends of the two plumb bobs respectively point to the pressure lever support frame and the screw jack support frame.

[0006] The overall height of the positioning tooling for manufacturing the pressing frame component of the ultra-thin calender does not exceed 170 cm, and the operator can directly manually operate on the ground. First, place the erected positioning tooling at the installation point of the pressing frame component of the ultra-thin calender, and then draw longitudinal centerlines on the pressure lever support frame and the screw jack support frame. Align the end of one plumb bob with the longitudinal centerline of the pressure lever support frame, then adjust the positioning adjustment device on the other plumb bob and drive the suspension line to move, and measure the distance between the two suspension lines at any time. Until the distance between the two suspension lines reaches the preset value, and after the two suspension lines are stationary, install the screw jack support frame on the pressing frame base and make the longitudinal centerline of the screw jack support frame align with the end of the plumb bob on the other suspension line, and then weld the pressure lever support frame and the screw jack support frame to the pressing frame base to complete the positioning installation. This positioning tooling is simple and convenient to operate, reduces the manufacturing man-hours and saves costs, and the manufacturing accuracy and measurement accuracy are precise. The manufactured pressing frame has good effects. When the pressure is applied to 5500 kg, the positioning pressure rod and the stress point of the pressing frame are perpendicular, without distortion, and the pressure ratio is stable.

[0007] The positioning adjustment device includes an adjustment scale, a scale support, a lead screw, and a lead screw support; the adjustment scale is erected above the cross bar; the adjustment scale is fixed on the top of the cross bar through the scale support; the lead screw is arranged directly below the adjustment scale; the lead screw is rotatably connected to the lead screw support; the lead screw support is fixed at the bottom of the cross bar; a lead screw slide seat is slidably sleeved on the lead screw; the top of the lead screw slide seat is fixedly welded with a pointer; the top of the pointer passes through the cross bar and points to the scale on the adjustment scale; the bottom of the lead screw slide seat is fixedly welded with a suspension line fixing piece; the top of the suspension line is fixed in the suspension line fixing piece.

[0008] When adjusting the position of the suspension line, rotate the lead screw to drive the lead screw slide seat to move on the lead screw, thereby driving the pointer and the suspension line on the lead screw slide seat to move, and then the suspension line drives the plumb bob to move. The structure is simple and the operation is convenient. At the same time, the displacement of the plumb bob can be observed through the pointer, further improving the adjustment accuracy.

[0009] The lead screw support is provided with shaft holes; both ends of the lead screw are respectively inserted into the shaft holes of two lead screw supports.

[0010] One end of the lead screw is fixed with an adjusting turntable by bolts. The operator manually rotates the adjusting turntable, thereby driving the lead screw to rotate, and the operation is convenient and simple.

[0011] The upper and lower surfaces of the cross bar are penetrated with limit waist holes; one end of the pointer passes through the limit waist hole and points to the adjustment scale.

[0012] The pointer moves along the length direction in the limit waist hole, restricting the self-rotation of the lead screw slider fixed below the pointer along with the lead screw.

[0013] The positioning tooling further includes a horizontal measuring rod; the horizontal measuring rod is arranged below the positioning and adjusting device and is in contact with the suspension line; the horizontal measuring rod is slidably mounted on the vertical rod.

[0014] The horizontal measuring rod is used to position two points in the horizontal direction of the two suspension lines, ensuring that the horizontal distance between the two suspension lines is a preset value, preventing the situation that when manually measuring two points on the two suspension lines, the two points are not on the same horizontal line, thereby causing an error in the measured distance value and resulting in inaccurate subsequent tooling installation.

[0015] Sliding sleeves are correspondingly fixed at both ends of the horizontal measuring rod; the sliding sleeves are slidably sleeved on the vertical rod.

[0016] The cross bar is fixedly connected to the tops of the two vertical rods respectively through gaskets at both ends.

[0017] The overall height of the positioning tooling for manufacturing the pressing frame component of the ultra-thin rolling mill does not exceed 170 cm, and the operator can directly perform manual operations on the ground. First, place the erected positioning tooling at the installation point of the pressing frame component of the ultra-thin rolling mill, and then draw longitudinal centerlines on the pressure lever support frame and the screw jack support frame. Align the end of one plumb bob with the longitudinal centerline of the pressure lever support frame, and then adjust the positioning adjustment device on the other plumb bob. Specifically, rotate the adjustment turntable to drive the screw rod to rotate, and then drive the screw rod slide to move on the screw rod, thereby driving the pointer and the suspension line on the screw rod slide to move. The pointer moves along its length direction within the limit waist hole, and then the suspension line drives the plumb bob to move. The structure is simple and the operation is convenient. At the same time, the displacement of the plumb bob can be observed through the pointer, further improving the adjustment accuracy. Locate two points on the two suspension lines in the horizontal direction through the horizontal measuring rod, and measure the horizontal distance between the two suspension lines at any time until the distance between the two suspension lines reaches the preset value. After the two suspension lines are stationary, install the screw jack support frame on the pressing frame base, and make the longitudinal centerline of the screw jack support frame align with the end of the plumb bob on the other suspension line. Then weld the pressure lever support frame and the screw jack support frame to the pressing frame base to complete the positioning installation. This positioning tooling is simple and convenient to operate, reduces the manufacturing man-hours and saves costs. The manufacturing accuracy and measurement accuracy are precise, and the manufactured pressing frame has good effects. When the pressure is increased to 5500 kg, the positioning pressure rod and the force application point of the pressing frame are perpendicular, without distortion, and the pressure ratio is stable.

The two vertical rods 2 are respectively fixed at both ends of the tooling base 1 by bolts. The cross bar 3 is erected between the tops of the two vertical rods 2. The positioning adjustment device 5 is fixedly installed on the cross bar 3. The plumb bob 4 is slidably fitted on the positioning adjustment device 5 through a suspension wire 41. A pressure frame base 1' is placed on the tooling base 1. Pressure lever support frames 2' and screw jack support frames 3' are respectively installed at both ends of the top of the pressure frame base 1'. The ends of the two plumb bobs 4 respectively point to the pressure lever support frame 2' and the screw jack support frame 3'.

[0030] The overall height of the positioning tooling for manufacturing the pressing frame component of the ultra-thin rolling mill does not exceed 170 cm, and the operator can directly perform manual operations on the ground. First, place the erected positioning tooling at the installation point of the pressing frame component of the ultra-thin rolling mill. Then, draw longitudinal centerlines on the pressure lever support frame 2' and the screw jack support frame 3'. Align the end of one plumb bob 4 with the longitudinal centerline of the pressure lever support frame 2'. Then, adjust the positioning adjustment device 5 on the other plumb bob 4 and drive the plumb line 41 to move. Measure the distance between the two plumb lines 41 at any time until the distance between the two plumb lines 41 reaches the preset value. After the two plumb lines 41 are stationary, install the screw jack support frame 3' on the pressing frame base 1' and make the longitudinal centerline of the screw jack support frame 3' align with the end of the plumb bob 4 on the other plumb line 41. Then, weld the pressure lever support frame 2' and the screw jack support frame 3' to the pressing frame base 1' to complete the positioning installation. This positioning tooling is simple and convenient to operate, reduces the manufacturing man-hours and saves costs. The manufacturing accuracy and measurement accuracy are precise. The produced pressing frame has good effects. When the pressure is increased to 5500 kg, the positioning pressure rod 6' and the stress point of the pressing frame are perpendicular, without distortion, and the pressure ratio is stable.

[0031] Refer to Figure 3 and Figure 4 , the positioning adjustment device 5 includes an adjustment scale 51, a scale support 53, a lead screw 54 and a lead screw support 56. The adjustment scale 51 is erected above the cross bar 3. The two ends of the adjustment scale 51 are respectively welded to two scale supports 53. The bottom ends of the scale supports 53 are embedded in the top surface of the cross bar 3. The lead screw 54 is arranged directly below the adjustment scale 51. The lead screw 54 is rotatably connected to the lead screw support 56. The top end of the lead screw support 56 is embedded in the bottom surface of the cross bar 3. A lead screw slide 55 is slidably sleeved on the lead screw 54. The top of the lead screw slide 55 is welded with a pointer 52. The top end of the pointer 52 passes through the cross bar 3 and points to the scale on the adjustment scale 51. The bottom of the lead screw slide 55 is fixedly welded with a plumb line fixing piece 58. The top end of the plumb line 41 is embedded in the plumb line fixing piece 58, and the embedded opening is sealed with glue.

[0032] When adjusting the position of the plumb line 41, rotate the lead screw 54 to drive the lead screw slide 55 to move on the lead screw 54, and then drive the pointer 52 and the plumb line 41 on the lead screw slide 55 to move. Then, the plumb line 41 drives the plumb bob 4 to move. The structure is simple and the operation is convenient. At the same time, the displacement of the plumb bob 4 can be observed through the pointer 52, further improving the adjustment accuracy.

[0033] The lead screw support 56 is provided with shaft holes. The two ends of the lead screw 54 are respectively inserted into the shaft holes of the two lead screw supports 56.

[0034] One end of the lead screw 54 is fixed with an adjusting turntable 57 by bolts. The operator manually rotates the adjusting turntable 57, thereby driving the lead screw 54 to rotate, which is convenient and simple to operate.

[0035] The positioning tooling further includes a horizontal measuring rod 6. The horizontal measuring rod 6 is arranged below the positioning and adjusting device 5 and is in contact with the suspension line 41. The horizontal measuring rod 6 is slidably mounted on the vertical rod 2.

[0036] The horizontal measuring rod 6 is used to position two points on the two suspension lines 41 in the horizontal direction, ensuring that the horizontal distance between the two suspension lines 41 is a preset value, preventing the two points on the two suspension lines 41 from not being on the same horizontal line when manually measuring the two points, thereby causing an error in the measured distance value and resulting in inaccurate subsequent tooling installation.

[0037] Sliding sleeves 61 are correspondingly fixed at both ends of the horizontal measuring rod 6. The sliding sleeves 61 are slidably sleeved on the vertical rod 2.

[0038] The cross bar 3 is fixedly connected to the tops of the two vertical rods 2 through the gaskets 31 at both ends respectively.

[0039] Refer to Figure 5 , a limiting waist hole 32 runs through the upper and lower surfaces of the cross bar 3. One end of the pointer 52 passes through the limiting waist hole 32 and points to the adjusting scale 51.

[0040] The pointer 52 moves along the length direction of the limiting waist hole 32, restricting the self-rotation of the lead screw slider 55 fixed below the pointer 52 along with the lead screw 54.

[0041] The working principle of this embodiment is as follows: The overall height of the positioning tooling made for the pressing frame component of the ultra-thin calender does not exceed 170 cm, and the operator can directly operate manually on the ground. First, place the erected positioning tooling at the installation point of the pressing frame component of the ultra-thin calender, and then draw the longitudinal centerlines on the pressure lever support frame 2' and the screw jack support frame 3'. Align the end of one plumb bob 4 with the longitudinal centerline of the pressure lever support frame 2', and then adjust the positioning adjustment device 5 on the other plumb bob 4. Specifically, rotate the adjustment turntable 57 to drive the screw rod 54 to rotate, and then drive the screw rod slide 55 to move on the screw rod 54, thereby driving the pointer 52 and the plumb line 41 on the screw rod slide 55 to move. Among them, the pointer 52 moves along its length direction within the limit waist hole 32, and then the plumb line 41 drives the plumb bob 4 to move. The structure is simple and the operation is convenient. At the same time, the displacement of the plumb bob 4 can be observed through the pointer 52, further improving the adjustment accuracy; Position two points on the two plumb lines 41 in the horizontal direction through the horizontal measuring rod 6, and measure the horizontal distance between the two plumb lines 41 at any time. Until the distance between the two plumb lines 41 reaches the preset value, and after the two plumb lines 41 are stationary, install the screw jack support frame 3' on the pressing frame base 1', and make the longitudinal centerline of the screw jack support frame 3' align with the end of the plumb bob 4 on the other plumb line 41, and then weld the pressure lever support frame 2' and the screw jack support frame 3' to the pressing frame base 1' to complete the positioning installation. This positioning tooling is simple and convenient to operate, reduces the manufacturing man-hours and saves costs. The manufacturing accuracy and measurement accuracy are precise. The produced pressing frame has good effects. When the pressure is applied to 5500 kg, the positioning pressure rod 6' and the force application point of the pressing frame are perpendicular, without distortion, and the pressure ratio is stable.
