Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to a pressure resistance welding cooling treatment device for steel grating processing. Background Art

[0002] Steel grating is a steel product made of flat steel that is cross-arranged at a certain interval and cross bars (twisted square steel, square steel, round steel, flat steel, etc.) and welded into a square grid in the middle. Steel grating is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc.

[0003] At present, the traditional pressure resistance welding cooling treatment device for steel grating processing only uses simple cooling methods, such as natural cooling or simple water sprinkling cooling, to achieve cooling of the steel grating after welding. It cannot ensure that the welding area is cooled evenly and efficiently, thus affecting the welding quality and the performance of the steel grating. At the same time, it is impossible to achieve the recycling of cooling water, resulting in a large amount of cooling water waste and increased production costs. Utility Model Content

A pressure resistance welding cooling treatment device for steel grating processing is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A pressure resistance welding cooling treatment device for steel grating processing, comprising:

[0007] A base, wherein the top of the base is rectangular and fixedly provided with four guide columns, the tops of the four guide columns are fixedly provided with a same top seat, the outsides of the four guide columns are slidably provided with a same moving frame, a hydraulic cylinder is embedded in the bottom of the top seat, the output end of the hydraulic cylinder is fixedly connected to the top of the moving frame, and a welding device is fixedly provided at the bottom of the moving frame;

[0008] A cooling component is respectively arranged on the mobile frame and the base and is used to cool the steel grating after pressure welding.

[0009] In a possible design, the cooling component includes two mounting plates symmetrically fixed on both sides of the mobile frame, a plurality of fixing frames are fixedly mounted on the bottom of the two mounting plates, nozzles are rotatably mounted on the inner sides of the plurality of fixing frames through a rotating shaft, the tails of the plurality of nozzles are fixedly connected to the same water supply pipe, a water storage tank is provided on the top of the base, a water pump is fixedly mounted on one side of the base, an input end of the water pump is fixedly connected to a water pumping pipe, one end of the water pumping pipe is sealed and passes through one side of the base to be connected to the water storage tank, and an output end of the water pump is fixedly connected to the water supply pipe.

[0010] In a possible design, a threaded rod is provided on one side of the fixing frame, one end of the threaded rod is fixedly connected to one of the rotating shafts on the fixing frame, an external thread of the threaded rod is connected to a locking knob, and an adjustment knob is provided on the other side of the fixing frame, and the adjustment knob is fixedly connected to another rotating shaft on the fixing frame.

[0011] In a possible design, a drain plate is detachably placed on the top of the base above the water storage tank, and handles are symmetrically provided on both sides of the drain plate.

[0012] In a possible design, a fan is fixedly disposed on one side of the top of the base, and an air outlet of the fan is fixedly connected to an air outlet hood.

[0013] In a possible design, the two guide columns located on the same side are fixedly provided with a same limiting frame on the outside, and the limiting frame is provided with a plurality of evenly distributed placement grooves for placing steel gratings.

[0014] In a possible design, the same conveying frame is fixedly provided on the outside of the two guide columns located on the other side, and the top of the conveying frame is rotatably provided with an electric roller for facilitating the conveyance of the steel grating.

[0015] In the present application, when starting to use, first inject an appropriate amount of cooling water into the water tank to provide sufficient water source for the cooling component, then place the leak plate above the water tank, ensure that the leak plate is embedded in the water tank so that its position is slightly lower than the water tank, so as to facilitate the collection of cooling water, and then place one end of the multiple steel gratings to be pressure welded in the placement groove of the limit frame, and the other end on the conveying frame, to ensure that the steel gratings are stable and easy to operate, then start the hydraulic cylinder, the output end of the hydraulic cylinder drives the movable frame to move downward along the guide column until the welding device contacts the steel grating to be processed, and the steel grating is pressure-resistance welded by the welding device to complete the welding operation. After the welding is completed, start the hydraulic cylinder again, and its output end retracts to drive the movable frame to rise to an appropriate height for cooling treatment, then start the water pump, the input end of the water pump draws cooling water from the water tank through the pumping pipe, and then transports it to each nozzle through the water supply pipe, so that the nozzle cools the welded steel grating Water spraying.

While the adjusting knob is rotating, the nozzle is driven to rotate through the rotating shaft, thereby adjusting its spraying angle. When the spraying angle is adjusted, rotate the locking knob in the opposite direction so that the locking knob rotates on the threaded rod until it engages with one side of the fixed frame to complete the limitation of the angle position of the nozzle. By adjusting the spraying angle of the nozzle, it can be ensured that the cooling water can be evenly sprayed on the steel grating. After the cooling is completed, start the electric roller, and the steel grating is transported to the next process for subsequent processing by the electric roller.

[0016] The utility model has the following beneficial effects:

[0017] In the utility model, by setting a cooling component, the input end of the water pump draws cooling water from the water storage tank through a pumping pipe, and then transports it to each nozzle through a water supply pipe, so that the nozzle sprays cooling water on the welded steel grating to achieve cooling, which can quickly reduce the temperature of the welding area, avoid the occurrence of annealing deformation, and ensure the material properties of the steel grating. During the spraying process, the cooling water falls on the leak plate and then returns to the water storage tank through the holes on the leak plate, so as to realize the recycling of cooling water, which not only reduces the production cost, but also reduces the waste of water resources.

[0018] The utility model provides a threaded rod, a locking knob and an adjusting knob. When the angle of the nozzle needs to be adjusted, the locking knob can be rotated to make the locking knob rotate on the threaded rod and disengage from the abutment with one side of the fixing frame. Then the adjusting knob can be rotated. When the adjusting knob is rotated, the nozzle is driven to rotate through the rotating shaft, thereby adjusting the spraying angle. When the spraying angle is adjusted, the locking knob is rotated in the opposite direction to make the locking knob rotate on the threaded rod until it abuts against one side of the fixing frame, thereby completing the definition of the nozzle angle position. By adjusting the spraying angle of the nozzle, it can be ensured that the cooling water can evenly cover the surface of the steel grating, thereby improving the cooling efficiency and avoiding the problems of local overheating or uneven cooling.

[0019] The utility model not only ensures the high efficiency of cooling treatment by setting the cooling component, but also realizes the recycling of cooling water, thereby improving production efficiency, reducing production costs, saving water resources and reducing pollution to the environment.
