Description

Technical Field

[0001] The present invention relates to the technical field of panel processing, and particularly to an arc pressing device for a vase pier bridge cap panel and a using method thereof. Background Technique

[0002] The pier body is the main body of the intermediate support structure of a multi-span bridge. The main materials are wood, stone, concrete, reinforced concrete and steel. In bridge construction at home and abroad, for cast-in-place piers, most of them adopt the conventional construction process of erecting scaffolding or self-dismantling brackets on the formwork and tying steel bars on site. In the construction of land viaduct piers in a few areas, the construction process of integrally manufacturing and installing the pier body steel cage has been applied. The cross-sectional size of its piers is small, the quality of the steel cage is light, and the construction environment is good. The steel formwork used for pouring the connecting piers of bridges and the vase-shaped piers with tie beams contains large curved surface parts. In the traditional process, after numerical control cutting, one person needs to straighten some panels, and two people weld simultaneously. During welding, two people are needed to assist in positioning welding. Moreover, the traditional bridge cap panel is composed of multiple small panels spliced together. The vase pier bridge cap panel is not a standard arc, but a hyperbolic arc.

[0003] After retrieval, the patent publication number CN110091124B discloses a construction process for the curved surface part of a bridge vase-shaped pier mold, which is characterized by including the following steps: (1) Rolling: Rolling a flat steel plate into a cylindrical steel plate through a rolling device; (2) Welding: Seam-welding the cylindrical steel plate obtained in the rolling step into a steel pipe; (3) Rotary rolling: Processing the steel pipe obtained in the welding step into a bent steel pipe through a rotary rolling machine; (4) Cutting: Cutting the bent steel pipe obtained in the rotary rolling step along its bending axis into a bent strip-shaped curved panel; (5) Welding: Welding the bent strip-shaped curved panel obtained in the cutting step into the curved surface part on the steel formwork; in the construction process for the curved surface part of the bridge vase-shaped pier mold, the bent steel pipe is cut into a bent strip-shaped curved panel, and the strip-shaped curved panel is used to replace multiple small curved panels welded sequentially from bottom to top in the prior art, reducing the cumbersome processes of non-linear welding and improving the construction efficiency.

[0004] The traditional process makes the splicing of the bridge cap very cumbersome, with extremely low efficiency and high labor consumption, resulting in a high production cost of the panel. Moreover, during the splicing of the vase pier, there are tensile stresses and other residual problems, making the splicing very difficult. The traditional process for splicing the bridge cap requires a large number of panels to be numerically controlled, greatly increasing the welding amount and grinding amount. The more panels are spliced, the more welds are generated, making the shape of the poured concrete not very beautiful. Summary of the Invention

[0005] The purpose of the present invention is to provide an arc pressing device for a vase pier bridge cap panel and a using method thereof to solve the problems raised in the above background technique.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an arc pressing device for a vase pier bridge cap panel, comprising a supporting device, a feeding device, a cooling device, an upper mold body, a lower mold body and a sliding block, a supporting frame is installed on one side of the upper outer wall of the supporting device, a lower mold body is installed on one side of the upper outer wall of the supporting device, the lower mold body is located inside the supporting frame, an upper mold body is arranged on the upper outer wall of the lower mold body, a hydraulic cylinder is installed on one side of the upper outer wall of the upper mold body, feeding devices are installed on both sides of the outer walls of the upper mold body, a cooling device is installed on one side of the outer wall of the lower mold body, the feeding device and the cooling device are cross-distributed, and a fixing block is installed on one side of the upper outer wall of the cooling device.

[0007] When using the arc pressing device for a vase pier bridge cap panel and its use method in the technical solution, the staff moves the material plate between the rollers through the lifting device of the device, and the rollers achieve the purpose of supporting the material plate. When the hydraulic cylinder is driven by the pump station to drive the upper mold body to move downward, the material plate first contacts with the lower mold body, and the support frame ensures the position stability through the slider and the slide groove. During the continuous downward pressure of the upper mold body, the material plate is pressed into the mold groove between the upper mold body and the lower mold body. After the shape of the material plate is bent, its size will change, so that the material plate located inside the roller enters. When the material plate is pressed, the upper mold body is driven upward by the hydraulic cylinder, and the displacement sensor detects the distance signal of the upper mold body. The external controller controls the cooling liquid to enter the inside of the shunt pipe and is atomized through the nozzle body. The fan body drives the air flow, so that the atomized cooling liquid enters the inside of the lower mold body, thereby achieving the purpose of cooling the material plate inside the lower mold body and avoiding the high temperature of the material plate after pressing and deformation.

[0008] Preferably, a pump station is installed on the outer wall of the support device away from the support frame. The pump station is connected to the hydraulic cylinder through a hydraulic oil pipe. The pump station can provide hydraulic power with a certain pressure and flow, and transmit it to the inside of the hydraulic cylinder through the hydraulic oil pipe, thereby driving the hydraulic cylinder to work.

[0009] Preferably, the outer wall of the upper end of the hydraulic cylinder is connected to the upper end of the inner wall of the supporting frame, and the position stability of the hydraulic cylinder is ensured, and various pressures generated during the construction of the hydraulic cylinder can be overcome.

[0010] Preferably, mold grooves are formed on the upper outer wall of the lower mold body and the lower outer wall of the upper mold body, and the mold grooves fit together.

[0012] The slider is slidably installed inside the chute, and the slider can move inside the chute.

[0013] Preferably, the feeding device further includes a support frame, a bushing, a roller and an anti-slip pad. The support frame is located on the outer wall of one side of the feeding device, and the support frame is connected to the slider. The support frame can move vertically through the slider, and the horizontal height of the support frame is lower than that of the upper die body;

[0014] The bushing is installed on the upper and lower sides of the inner wall of the support frame, and the roller is rotatably installed inside the bushing. The roller ensures the stability of the rotation position through the bushing, and the material plate can be located between the rollers. The four rollers achieve the purpose of supporting the material plate;

[0015] The anti-slip pad is fixedly attached to the outer wall of the roller, and the anti-slip pads are distributed in a circular array on the outer wall of the roller. The anti-slip pad increases the friction between the roller and the material plate, and prevents the material plate from moving back and forth on the outer wall of the roller.

[0016] Preferably, a displacement sensor is installed on the outer wall of one side of the cooling device. The displacement sensor detects the distance from the upper die body. After the upper die body and the lower die body extrude and form the material plate, the upper die body is driven by the hydraulic cylinder to move upward, so as to detect the signal of the upper die body moving away through the displacement sensor.

[0017] Preferably, the fixing block has a circular-arrayed spray head body inserted on its outer wall. The spray head body has a shunt pipe inserted through one end of the outer wall of the fixing block. The cooling liquid enters the interior of each spray head body through the shunt pipe and is evenly sprayed out through the spray head body. The spraying direction of the spray head body is inside the lower die body.

[0018] Preferably, a through hole is formed inside the fixing block, and the through hole is used to ensure air flow;

[0019] One side of the inner wall of the through hole is provided with a fan body. The fan body can drive air flow, so that the air flow blows into the lower die body, thereby driving the atomized cooling liquid to flow, and can control the flow direction of the atomized liquid.

[0023] Step 3: During the continuous downward pressing of the upper die body, the material plate is pressed into the die groove between the upper die body and the lower die body. After the shape of the material plate is bent, its size will change, so that the material plate located inside the roller enters;

[0024] Step 4: When the pressing of the material plate is completed, the upper die body is driven upward by the hydraulic cylinder, and the displacement sensor detects the signal of the upper die body moving away. The external controller controls the cooling liquid to enter the inside of the shunt pipe and atomizes through the nozzle body, and the fan body drives the air flow, so that the atomized cooling liquid enters the inside of the lower die body, achieving the purpose of cooling the material plate inside the lower die body and avoiding the high temperature of the material plate after pressing and deformation.
