Description

Technical Field

[0001] The utility model relates to the technical field of cold rolling, in particular to a heating device for a cold rolling roller die. Background Art

[0002] Cold rolling rollers refer to the rollers used in cold rolling, mainly used for rolling plates and strips. Since the support rollers are a self-contained system, cold rolling rollers are often narrowly referred to as cold rolling working rollers. Cold rolling rollers must have sufficient strength, uniform high hardness and surface quality to withstand extremely high rolling forces, ensure sufficient wear resistance, and meet the precision requirements of rolled materials. Forged steel rollers that can be quenched to a high hardness are used as cold rolling rollers. When manufacturing cold-rolled steel plates, cold rolling rollers are often preheated. Preheating not exceeding 80 degrees can improve the quality of subsequent rolled steel plates. At the same time, the cold rolling roller molds need to be replaced according to different rolling requirements.

[0003] When the existing cold rolling roller is being molded and demolded, the current equipment usually needs to be installed and disassembled manually. Since the roller is heavy, manual disassembly and assembly is time-consuming and labor-intensive. Generally, it takes at least several workers working at the same time for several hours to replace a cold rolling roller mold. Moreover, manual replacement is entirely based on the workers' feelings and experience, which can easily cause damage to the cold rolling roller mold and the cold rolling roller, reducing its service life, increasing production costs, and bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a heating device for the cold rolling roller mold. Utility Model Content

[0011] Preferably, the limiting screw passes through the through slot, the second through hole, and the first through hole in sequence, and the limiting screw is detachably connected to the limiting nut.

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, the cold rolling roller die is heated by a heating net, which is electrically connected to a wire and a plug. When the plug is connected to an external power source, the heating net can be powered on for heating. At this time, the inside of the heat insulation sleeve is heated, thereby heating the cold rolling roller die and the cold rolling roller. The cold rolling roller and the cold rolling roller die are separated by a slider, so that the distance between the cold rolling roller and the cold rolling roller die can be maintained, thereby avoiding the problem of expansion and deformation of the cold rolling roller during the heating process caused by direct heating, thereby increasing the practicality of the device.

[0015] 2. In the utility model, the heat insulating sleeve and the cold rolling roller are fixed by the set limit nut. During installation, the limit screw is passed through the first through hole, the second through hole and the through groove in sequence, so that one end of the limit screw enters the shaft seat, and one end of the limit screw is rotated and tightened in the shaft seat, and then the limit nut is screwed on the other end of the limit screw. The heat insulating sleeve and the cold rolling roller are fixed by the limit screw. After the heating work of the cold rolling roller mold is completed, the limit of the limit screw, the limit nut and the shaft seat is released. When the limiting screw is pulled out, the cold rolling roller will be separated from the cold rolling roller mold by its own weight when demolding. The cold rolling roller will slide vertically into the discharge barrel through the sliding block of the slider in the through groove. This will save time, effort and cost for demolding the cold rolling roller, and will not cause damage to the cold rolling roller mold and the cold rolling roller, thereby increasing the practicality of the device. The limiting screw is used to limit the insulation sleeve and the cold rolling roller, making the loading and unloading between the insulation sleeve and the cold rolling roller easier and faster.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1-4As shown, a heating device for a cold rolling roller die is provided. When in use, the mounting frame 1 and the heat insulating sleeve 5 are connected by the connecting column 2, so that the heat insulating sleeve 5 is stably suspended, and the limiting screw 9 is passed through the first through hole 12, the second through hole 13, and the through groove 15 in sequence, so that one end of the limiting screw 9 enters the shaft seat 18. The shaft seat 18 is provided with a thread, and the shaft seat 18 and the limiting screw 9 can be connected by rotation through the thread. Then, the limiting screw 9 is rotated and tightened in the shaft seat 18 to complete the installation of the shaft seat 18 and the limiting screw 9, and then the limiting nut 8 is screwed on the other end of the limiting screw 9. The limiting nut 8 is tightly attached to the heat insulating sleeve 5, so that the heat insulating sleeve 5 and the cold rolling roller 4 are fixedly connected. At this time, the plug 11 is connected to an external power supply, and the heating network 7, the wire 10, and the plug 11 are electrically connected to each other. Then, the heating network 7 starts to heat after being energized, so that the inside of the heat insulating sleeve 5 is heated, and the cold rolling roller 4 and the cold rolling roller die 14 are heated.

[0023] Embodiment 2, as Figure 1-4 As shown, a heating device for a cold rolling roller die is provided. When the cold rolling roller 4 and the cold rolling roller die 14 are heated, two sets of sliders 16 are provided between the cold rolling roller 4 and the cold rolling roller die 14. The sliders 16 pull the distance between the cold rolling roller 4 and the cold rolling roller die 14 apart to avoid the problem of expansion and deformation of the cold rolling roller 4 during the heating process. After the heating is completed, the limit nut 8 is screwed off, and the limit screw 9 is rotated to release the limit fixation between the limit screw 9 and the shaft seat 18, and the limit screw 9 is pulled out, so that the heat insulation sleeve 5 and the cold rolling roller 14 are in a state of being locked. The rollers 4 are no longer connected, so the cold rolling roller 4 begins to be demolded. The cold rolling roller 4 is demolded by its own weight. The cold rolling roller 4 slides in the through groove 15 through the slider 16, thereby maintaining the vertical drop of the cold rolling roller 4, and finally enters the discharge barrel 6 to complete the demolding of the cold rolling roller 4, so that the cold rolling roller 4 leaves the cold rolling roller mold 14. In this way, demolding the cold rolling roller 4 saves time, labor, and cost, and will not cause damage to the cold rolling roller mold 14 and the cold rolling roller 4, thereby increasing the practicality of the device.

[0024] How it works

[0025] It should be noted that the utility model is a heating device for a cold rolling roller die. When in use, the limiting screw 9 is passed through the first through hole 12, the second through hole 13, and the through groove 15 in sequence, so that one end of the limiting screw 9 is rotated and tightened in the shaft seat 18, and the installation of the shaft seat 18 and the limiting screw 9 is completed. Then, the limiting nut 8 is screwed on the other end of the limiting screw 9, and the limiting nut 8 is tightly attached to the heat insulation sleeve 5, so that the heat insulation sleeve 5 and the cold rolling roller 4 are fixedly connected. At this time, the plug 11 is connected to an external power supply, so the heating network 7 starts to heat after being energized, so that the inside of the heat insulation sleeve 5 is heated, and the cold rolling roller 4 and the cold rolling roller die 14 are heated. When heating the cold-rolling roller 4 and the cold-rolling roller die 14, two sets of sliders 16 are arranged between the cold-rolling roller 4 and the cold-rolling roller die 14. The sliders 16 pull the distance between the cold-rolling roller 4 and the cold-rolling roller die 14 apart to avoid the problem of expansion and deformation of the cold-rolling roller 4 during the heating process. After the heating is completed, the limit nut 8 is screwed off and the limit screw 9 is pulled out, so that the insulation sleeve 5 and the cold-rolling roller 4 are no longer connected, and the cold-rolling roller 4 begins to be demoulded. The cold-rolling roller 4 is demoulded by its own weight. In this way, demoulding the cold-rolling roller 4 is more time-saving, labor-saving, and cost-saving, and will not cause damage to the cold-rolling roller die 14 and the cold-rolling roller 4, thereby increasing the practicality of the device.
