Description

Technical Field

[0001] This utility model belongs to the field of quenching technology, and in particular relates to a large-scale dual-frequency support roller quenching machine tool. Background Technology

[0002] Quenching machine tools mainly consist of three parts: the quenching machine tool itself, a medium- and high-frequency power supply, and a cooling device. The quenching machine tool itself comprises a bed, loading and unloading mechanism, clamping and rotating mechanism, quenching transformer and resonant circuit, cooling system, quenching fluid circulation system, and electrical control system. Quenching machine tools are generally single-station. Structurally, quenching machine tools are divided into two main categories: vertical and horizontal. Users can select the quenching machine tool according to the quenching process. For special parts or special processes, special quenching machine tools can be designed and manufactured according to the heating process requirements.

[0003] During production, support rollers need to be quenched. However, because support rollers are generally large in size, they are inconvenient to install in the equipment, which leads to uneven heating and easily affects the quality of subsequent quenching. In view of this, we propose a large-scale dual-frequency support roller quenching machine. Utility Model Content

[0004] The purpose of this invention is to provide a large-scale dual-frequency support roller quenching machine tool to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a large-scale dual-frequency support roller quenching machine tool, comprising:

[0006] A base plate, on the top surface of which four mounting rods are fixedly installed, and the same lifting frame is slidably installed on the four mounting rods. A movable plate is slidably installed inside the lifting frame. A semi-circular box is fixedly installed on the bottom surface of the movable plate. Multiple nozzles are fixedly installed on the inner side wall of the semi-circular box. A quenching sensor is fixedly installed on the inner side wall of the semi-circular box.

[0007] A movable component, which is disposed within the lifting frame and is used to move the movable plate;

[0008] A fixed platform is fixedly installed on the top surface of a base plate. A movable platform is slidably installed on the top surface of the base plate. A first mounting plate and a second mounting plate are fixedly installed on the top surfaces of both the fixed platform and the movable platform. A first turntable is rotatably installed in each of the two first mounting plates. A second turntable is rotatably installed in each of the two second mounting plates. Four clamping plates are slidably installed on one side of each of the two first turntables.

[0009] Two sets of adjustment components are respectively set between two first turntables and two second turntables, and are used to drive multiple clamping plates to move. The support roller to be quenched is placed between the two first turntables. According to the length of the support roller, the first telescopic cylinder is activated to push the moving platform to move, thereby adjusting the distance between the two first mounting plates, so that the multiple clamping plates on the two first turntables can clamp the two ends of the support roller. When clamping the two ends of the support roller, the second telescopic cylinder is activated to push the moving plate to move. When the moving plate moves, the cooperation of the second connecting seat, the connecting rod and the first connecting seat will drive multiple sliders to move. The multiple sliders will drive multiple clamping plates to move, adjusting the distance between the multiple clamping plates, thereby achieving clamping of the two ends of the support roller and fixing the support roller.

[0010] In the above technical solution, the moving component further includes a lead screw, which is rotatably installed inside the lifting frame. The lead screw is threadedly connected to the moving plate. A motor A is fixedly installed on one side of the lifting frame. One end of the output shaft of the motor A is fixedly connected to one end of the lead screw. When the motor A is started, it drives the lead screw to rotate. When the lead screw rotates, the moving plate will move. At this time, the semi-circular box will move with the moving plate, which facilitates quenching at any position of the support roller and enhances the convenience of processing.

[0011] In the above technical solution, further, the adjusting assembly includes four sliders, which are slidably mounted inside a first turntable. Four first connecting seats are slidably mounted on the other side of the first turntable. One end of each of the four sliders is fixedly connected to one side of one of four clamping plates, and the other end of each slider is fixedly connected to one side of one of the four first connecting seats. Multiple side rods are fixedly mounted on one side of the second turntable, with one end of each side rod fixedly connected to the other side of the first turntable. A common movable disk is slidably mounted on each of the side rods. Four second connecting seats are fixedly mounted on one side of the movable disk. Each of the four connecting seats has a connecting rod rotatably installed inside. The other ends of the four connecting rods are rotatably installed in the four first connecting seats respectively. A second telescopic cylinder is fixedly installed on one side of the second turntable. One end of the second telescopic cylinder is fixedly connected to the other side of the moving disk. When clamping the two ends of the support roller, the second telescopic cylinder is activated to push the moving disk to move. When the moving disk moves, the cooperation of the second connecting seat, connecting rod, and first connecting seat will drive multiple sliders to move. The multiple sliders will drive multiple clamping plates to move, adjusting the distance between the multiple clamping plates, thereby achieving clamping of the two ends of the support roller and fixing the support roller.

[0012] In the above technical solution, a side frame is fixedly installed on one side of one of the second mounting plates, and a motor B is fixedly installed on one side of the side frame. One end of the output shaft of the motor B is fixedly connected to the other side of the second turntable. When the support roller is quenched, the motor B can be started to drive the second turntable to rotate. When the second turntable rotates, it will drive the first turntable to rotate. Since the support roller is clamped between the two first turntables, the support roller will also rotate with the support roller. This makes it convenient to quench the support roller.

[0013] In the above technical solution, a first telescopic cylinder is further fixedly installed on the top surface of the base plate. One end of the first telescopic cylinder is fixedly connected to one end of one of the second mounting plates. The support roller to be quenched is placed between the two first turntables. According to the length of the support roller, the first telescopic cylinder is activated to push the moving table to move, thereby adjusting the distance between the two first mounting plates, so that the multiple clamping plates on the two first turntables can clamp the two ends of the support roller.

[0014] In the above technical solution, a fixing ring is fixedly installed on the bottom surface of the lifting frame, and a water pump and a water storage tank are fixedly installed on the top surface of the base plate. The water pump is equipped with a water pumping pipe and a water delivery hose. One end of the water pumping pipe is fixedly connected to the water storage tank, and one end of the water delivery hose passes through the fixing ring and is fixedly connected to the semi-circular box. When the support roller is quenched, the water pump can be started to transport the quenching liquid in the water storage tank to the semi-circular box through the water pumping pipe and the water delivery hose. Then, multiple nozzles are started to spray the quenching liquid onto the surface of the support roller.

[0015] In the above technical solution, further, the top of the four mounting rods is fixedly installed with the same top plate, and the bottom surface of the top plate is fixedly installed with a third telescopic cylinder. One end of the third telescopic cylinder is fixedly connected to the top surface of the lifting frame. When the third telescopic cylinder is activated, the lifting frame is driven to descend. When the semicircular box approaches the support roller, the quenching sensor inside the semicircular box is activated, and the support roller will be quenched.

[0016] The beneficial effects of this utility model are:

[0017] 1. This large dual-frequency support roller quenching machine places the support roller to be quenched between two first turntables. According to the length of the support roller, the first telescopic cylinder is activated to push the moving table to move, thereby adjusting the distance between the two first mounting plates. This facilitates the clamping plates on the two first turntables to clamp the two ends of the support roller. When clamping the two ends of the support roller, the second telescopic cylinder is activated to push the moving plate to move. When the moving plate moves, the cooperation of the second connecting seat, connecting rod, and first connecting seat will drive multiple sliders to move. The multiple sliders will drive multiple clamping plates to move, adjusting the distance between the multiple clamping plates, thereby achieving clamping of the two ends of the support roller and fixing the support roller.

[0018] 2. In this large dual-frequency support roller quenching machine, when the two ends of the support roller are clamped by multiple clamping plates, the third telescopic cylinder is activated to drive the lifting frame to descend. When the semi-circular box approaches the support roller, the quenching inductor inside the semi-circular box is activated, and the support roller will be quenched. During the quenching of the support roller, motor B can be activated to drive the second turntable to rotate. When the second turntable rotates, it will drive the first turntable to rotate. Since the support roller is clamped between the two first turntables, the support roller will also rotate with the support roller, which facilitates the quenching of the support roller.

[0019] When quenching the support roller, a water pump can be started to transport the quenching liquid in the storage tank to the semi-circular box through the water pumping pipe and water delivery hose. Then, multiple nozzles are started to spray the quenching liquid onto the surface of the support roller. When the support roller is quenched, motor A is started to drive the lead screw to rotate. When the lead screw rotates, the moving plate will move. At this time, the semi-circular box will move with the moving plate, which makes it convenient to quench the support roller at any position, enhances the convenience of processing, and is quite practical.
