Description

Technical Field

[0001] The utility model relates to the technical field of graphite mold processing, in particular to a cutting device for graphite mold processing. Background Art

[0002] A graphite mold is a mold mainly composed of graphite material and is used in high-temperature and high-pressure environments. Due to the excellent high-temperature resistance, corrosion resistance, electrical conductivity, lubrication and other properties of graphite, graphite molds have been widely used in many industrial fields, especially in industries such as metallurgy, casting, forging and glass manufacturing.

[0003] Currently, graphite molds are usually of fixed size during production, and then they are cut into the required size by a cutting device according to their different uses. When the existing cutting device cuts it, to avoid displacement during the cutting process, it is first fixed on the fixed seat of the cutting device, and then the cutting device is started for cutting. After cutting is completed, the fixation is cancelled. For example, a cutting device for graphite mold processing disclosed in the utility model patent with the application number CN202323192489.0 clamps the graphite mold by rotating a bidirectional screw rod, and then starts a hydraulic telescopic rod to cut the mold with a cutting head. However, the method of separately operating the pressing and cutting is rather cumbersome, which not only increases the labor intensity of the operating workers but also reduces the cutting efficiency.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The cutting device for processing graphite molds of the present utility model, by setting a cutting assembly and a pressing assembly, when in use, place the graphite mold on the fixing frame, and make one end of the graphite mold abut against the pushing plate. The cutting end of the graphite mold is located below the cutting knife. Then, control the pneumatic telescopic rod to move the mounting plate downward. The downward movement of the mounting plate drives the pressing plate and the cutting knife to move downward. When the pressing plate moves downward and contacts the graphite mold, the mounting plate moves downward to compress the pressing spring. The reaction force of multiple groups of pressing springs can make the pressing plate press the graphite mold. After pressing the graphite mold, the cutting knife moves downward to cut the graphite mold.

[0019] The cutting device for processing graphite molds of the present utility model, by setting a pushing assembly, when it is necessary to adjust the cutting position of the graphite mold, rotate the screw rod. The rotation of the screw rod and the threaded fit with the slider can make the slider move along the chute. The movement of the slider can drive the pushing plate to move, thereby adjusting the distance between the pushing plate and the cutting knife in the horizontal direction. At this time, after the graphite mold abuts against the pushing plate, the cutting position of the graphite mold can be changed, which is convenient for adjusting the cutting position of the graphite mold according to requirements and improves the practicability of the device.

[0020] The cutting device for processing graphite molds of the present utility model, by setting a pressing assembly, the operator can also determine the pressing strength according to the hardness of the graphite mold. After determining the pressing strength, rotate the pressure regulating nut.

The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope that the present utility model can be implemented.

[0035] Such as Figures 1-3As shown in the figure, an embodiment of the present utility model provides a cutting device for processing graphite molds, which includes a frame 100, a cutting assembly 200, and a pressing assembly 300. Among them, the frame 100 is provided with a fixed frame 110 for placing the graphite mold to be cut, and a feeding channel 120 is formed for the graphite mold to be cut to pass through. The cutting assembly 200 includes a mounting plate 210 arranged on the frame 100, a cutting tool 220 arranged on the mounting plate 210, and a pneumatic telescopic rod 230 arranged on the top of the frame 100. The pneumatic telescopic rod 230 is connected to the mounting plate 210 to drive the mounting plate 210 to slide in the vertical direction. The pressing assembly 300 includes an elastic telescopic member arranged on the mounting plate 210 and a pressing plate 310 arranged on the elastic telescopic member. The pressing plate 310 is located below the side end of the cutting tool 220 close to the fixed frame 110.

[0036] In the embodiment of the present utility model, when it is necessary to cut the graphite mold to be cut, the graphite mold to be cut is placed on the fixed frame 110. When the cutting end required for cutting the graphite mold is located below the cutting tool 220, then the pneumatic telescopic rod 230 is controlled to drive the mounting plate 210 to drive the cutting tool 220 and the pressing plate 310 arranged on the elastic telescopic member to move downward synchronously. When the pressing plate 310 presses the graphite mold to be cut, the cutting tool 220 can cut it, realizing the synchronous pressing and cutting of the graphite mold, which is convenient for cutting, reduces the labor intensity of the operator, and improves the cutting efficiency.

[0037] Specifically, as Figures 1-3 shown, in the embodiment of the present utility model, the elastic telescopic member includes a fixed plate 320 arranged on the mounting plate 210, a plurality of pressure regulating bolts 330, a plurality of pressure regulating nuts 340, and a plurality of pressing springs 350. The mounting plate 210 is provided with a pushing hole for the pressure regulating bolt 330 to be inserted. One end of the pressure regulating bolt 330 slides through the pushing hole and is screwed with the pressure regulating nut 340, and the other end is connected to the pressing plate 310. The pressure regulating bolt 330 is sleeved with a pressing spring 350. The two ends of the pressing spring 350 respectively abut against the lower end of the fixed plate 320 and the upper end of the pressing plate 310. Among them, the number of the pressure regulating bolts 330, the pressure regulating nuts 340, and the pressing springs 350 is matched, and can be two, three, four, etc.

[0038] During use, when the pneumatic telescopic rod 230 moves the mounting plate 210 downward, the downward movement of the mounting plate 210 drives the fixed plate 320 downward, and the downward movement of the fixed plate 320 drives the pressing plate 310 downward. When the pressing plate 310 moves downward and contacts the graphite mold, the fixed plate 320 moves downward to compress the pressing spring 350. The reaction force of the pressing spring 350 can make the pressing plate 310 press the graphite mold. It is convenient to press the graphite mold. And since the pressing plate 310 is located below the cutting knife 220, therefore, after the pressing plate 310 presses the graphite mold, the cutting knife 220 can cut the graphite mold. The pressing and cutting of the graphite mold are carried out simultaneously. At the same time, the operator can also determine the pressing strength according to the hardness of the graphite mold. After determining the pressing strength, rotate the pressure regulating nut 340. The pressure regulating nut 340 drives the relative distance between the fixed plate 320 and the pressing plate 310 to change through the pressure regulating bolt 330. At this time, the pressing spring 350 adjusts the extrusion strength by changing its own pre-compression length, effectively improving the adaptability of the device to graphite molds of different hardnesses, greatly enhancing the versatility of the device, and thus enhancing the practicality of the device.

[0039] Based on the above solution, as Figures 1-3 shown, in the embodiment of the present invention, a flexible fixing pad 360 is provided at the bottom of the pressing plate 310 to adapt to the minute unevenness on the surface of the graphite mold, ensure that the pressure is evenly distributed on the entire contact surface, thereby avoiding damage or deformation of the mold caused by excessive local stress, and at the same time can effectively increase the friction between the mold and the pressing plate 310, prevent the mold from sliding or shifting during the processing, and ensure the cutting accuracy and consistency. The flexible fixing pad 360 can be made of rubber material.

[0040] Based on the above solution, in another embodiment of the present invention, in order to improve the stability during the operation of the device, a locknut for applying a pre-tightening force to the pressure regulating nut 340 can be screwed on the outer surface of the pressure regulating bolt 330. Specifically, the top end of the pressure regulating nut 340 abuts against the bottom end of the locknut, thereby reducing the probability of the pressure regulating nut 340 loosening.

[0041] Based on the above solution, as Figures 4-5 shown, in the embodiment of the present invention, a pushing assembly 400 is further included. The pushing assembly 400 is used to push the graphite mold to be cut on the fixed frame 110 below the cutting knife 220 and the pressing plate 310. When it is necessary to cut the graphite mold, by placing the graphite mold on the fixed frame 110 and making one end thereof abut against the pushing assembly 400, the cutting position of the graphite mold can be adjusted according to the needs through the pushing assembly 400, improving the practicality of the device.

[0042] Specifically, as Figures 4-5As shown in the figure, in the embodiment of the present utility model, the pushing assembly 400 includes a pushing plate 410 disposed on the fixing frame 110. Two sets of slideways 420 are provided on one side of the fixing frame 110 away from the cutting knife 220. Two sets of sliders 430 are provided at the lower end of the pushing plate 410 corresponding to the two sets of slideways 420. The two sets of sliders 430 are slidably disposed in the two sets of slideways 420. When the graphite mold needs to be cut, by placing the graphite mold on the fixing frame 110 and making one end thereof abut against the pushing plate 410, the pushing plate 410 can be pushed to make its cutting end located below the cutting knife 220. At the same time, the cooperation of the provided slideways 420 and the sliders 430 can improve the stability of the pushing plate 410 during movement, thereby improving the stability of the pushing plate 410 in pushing the graphite mold.

[0043] Based on the above solution, as Figures 4-5 shown, in the embodiment of the present utility model, it further includes a driving member. A chute 440 is provided in each of the two sets of slideways 420. The slider 430 can be slidably disposed in the chute 440 along the length direction of the slideway 420. The driving member is rotatably disposed in one of the chutes 440 and is threadedly connected to the slider 430 in this chute 440, so as to drive the slider 430 to slide in the slideway 420 by rotating the driving member. The driving member facilitates the movement of the pushing plate 410 in the chute 440, thus facilitating use.

[0044] Specifically, as Figures 4-5 shown, in the embodiment of the present utility model, the driving member includes a screw rod 450. The screw rod 450 is rotatably disposed in the chute 440 and is threadedly connected to the slider 430. By rotating the screw rod 450, the rotation of the screw rod 450 and the threaded cooperation with the slider 430 can make the slider 430 move along the chute 440. The movement of the slider 430 can drive the movement of the pushing plate 410, thereby adjusting the distance between the pushing plate 410 and the cutting knife 220 in the horizontal direction, so as to facilitate adjusting the cutting position of the graphite mold according to requirements and improve the practicability of the device. At the same time, in order to facilitate the rotation of the screw rod 450, a hand wheel 460 is provided on the screw rod 450, and a plurality of anti-slip lines or anti-slip grooves are provided on the hand wheel 460 to avoid slipping and affecting the operation.

[0045] Based on the above solution, as Figures 1-3 shown, in the embodiment of the present utility model, it further includes a sliding assembly 500. The sliding assembly 500 includes a sliding seat 510 and a sliding rail 520. Sliding seats 510 are provided at both ends of the mounting plate 210. The machine frame 100 is provided with sliding rails 520 corresponding to the two sets of sliding seats 510. The sliding seats 510 are slidably disposed on the sliding rails 520. The cooperation of the sliding seats 510 and the sliding rails 520 can improve the stability of the mounting plate 210 during movement, thereby improving the stability of the pressing plate 310 in pressing the graphite mold and the cutting knife 220 in cutting the graphite mold.

[0046] The specific working process of a graphite mold cutting device provided by an embodiment of the present utility model is as follows:

[0047] First, place the graphite mold on the fixing frame 110, and make one end of the graphite mold abut against the pushing plate 410. The cutting end of the graphite mold is located below the cutting knife 220. Then, control the pneumatic telescopic rod 230 to move the mounting plate 210 downward. The downward movement of the mounting plate 210 drives the pressing plate 310 and the cutting knife 220 to move downward. When the pressing plate 310 moves downward and contacts the graphite mold, the mounting plate 210 moves downward to squeeze the pressing spring 350. The reaction forces of multiple groups of pressing springs 350 can make the pressing plate 310 press the graphite mold. After pressing the graphite mold, the cutting knife 220 moves downward to cut the graphite mold. The pressing and cutting of the graphite mold are carried out synchronously, which is convenient for cutting the graphite mold, reduces the labor intensity of the operator, and improves the cutting efficiency of the graphite mold.

[0048] When it is necessary to adjust the cutting position of the graphite mold, rotate the screw rod 450. The rotation of the screw rod 450 and the threaded fit with the slider 430 can make the slider 430 move along the chute 440. The movement of the slider 430 can drive the pushing plate 410 to move, thereby adjusting the distance between the pushing plate 410 and the cutting knife 220 in the horizontal direction. At this time, after the graphite mold abuts against the pushing plate 410, the cutting position of the graphite mold can be changed, which is convenient for adjusting the cutting position of the graphite mold according to requirements and improves the practicability of the device.

[0049] At the same time, the operator can also determine the pressing strength according to the hardness of the graphite mold. After determining the pressing strength, rotate the pressure regulating nut 340. The pressure regulating nut 340 drives the relative distance between the fixing plate 320 and the pressing plate 310 to change through the pressure regulating bolt 330. At this time, the pressing spring 350 adjusts the extrusion strength by changing its own pre-compression length, effectively improving the adaptability of the device to graphite molds of different hardnesses, greatly enhancing the versatility of the device, and thus enhancing the practicability of the device.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
