Technical Field

[0001] The invention relates to the field of automobile parts processing, and more specifically to a cutting device for aluminum die castings of automobile parts. Background Art

[0002] Auto parts are the various units that make up the whole car and a kind of product that serves the car; there are many kinds of auto parts, some of which are usually made of sand molds or metal molds to pour heated liquid aluminum or aluminum alloy into the mold cavity to obtain parts of various shapes and sizes. Such parts are called aluminum die castings; In actual production, in order to improve production efficiency, a metal mold is often provided with multiple cavities in series, so as to produce multiple parts at one time. However, since the cavities are connected in series through the nozzles, the aluminum die castings need to be truncated after forming. Common casting cutting methods are mostly semi-manual and semi-mechanized, that is, the joints of multiple castings connected together are manually pushed to the bottom of the cutting disc, and then the cutting disc cuts the joints of the castings. On the one hand, this method is inefficient and affects the cutting speed. On the other hand, manual operation is prone to errors, affecting the cutting quality. Summary of the invention

[0006] Furthermore, a first spring is fixedly connected between the upper end of the first slide and the top of the first slide groove at the lower end, and the elastic force of the first spring is greater than the friction resistance encountered by the first slide when sliding inside the first slide groove. When the electric telescopic cylinder is in a retracted state, the distance between the pressure plate and the first slide is greater than the width of the pad. When the electric telescopic cylinder is in an extended state, the lower end of the pressure plate is in contact with the first slide but no extrusion force is generated.

A fixing nut is threadedly connected to the end of the drive shaft away from the rotating plate.

[0008] Furthermore, the friction resistance between the second slide seat and the second slide groove is greater than the force exerted on the rotating plate when the rotating plate rotates. After the rotating plate rotates forty-five degrees clockwise, the pad is pushed to the bottom of the pressure plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This solution controls the cutting position of the casting by the cutting disc by driving the rotating plate through the casting, ensuring that the spacing of each cut is the same. After the casting is cut, it falls naturally, and the subsequent workpieces are continuously transported to the bottom of the cutting disc for cutting. The entire cutting process does not require human intervention, and the cutting efficiency and accuracy are high.

[0016] (2) This solution can change the pushing distance of the driving push plate when the turn plate rotates by inserting the driving shaft into different fixing holes for fixing. At the same time, the turn plate can also slide in the second slide groove through the second slide seat, thereby adjusting the distance between the turn plate and the transmission component, thereby realizing the adjustment of the casting cut-off distance, so that castings of different lengths can be cut off.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 , Figure 2 and Figure 4 , a device for cutting off aluminum die-castings of automobile parts, comprising a base 1, the upper end of the base 1 is fixedly connected to a frame 2, and the upper part of the frame 2 is provided with a conveying assembly 3 for conveying aluminum die-castings, a first support frame 5 is fixedly connected to the left side of the upper end of the frame 2, and the first support frame 5 is provided with a first slide 6 at both upper and lower ends, a first slide seat 7 is slidably connected to the inside of the first slide 6 at the lower end, and a second drive motor 8 is fixedly connected to the left side of the first slide seat 7, and a cutting disc 9 is fixedly connected to the output shaft of the second drive motor 8, and a first drive motor 4 for driving the conveying assembly 3 to work is fixedly connected to the right side of the front end of the frame 2, and the first drive motor 4 is electrically connected to an external power supply; A truncation assembly 10 for controlling the truncation distance is provided on the left side of the upper end of the base 1, and the truncation assembly 10 includes a second support frame 101 fixedly connected to the left side of the upper end of the base 1, and a rotating plate 104 is provided on the upper part of the second support frame 101, and the upper parts of the front and rear ends of the rotating plate 104 are fixedly connected to the driving shaft 105, and the outer part of the driving shaft 105 is movably connected to the push plate 106, and the right side of the push plate 106 is hinged with a pad 107, and the inner part of the first slide groove 6 at the upper end is fixedly connected to an electric telescopic cylinder 108, and the telescopic end of the electric telescopic cylinder 108 is fixedly connected to a pressing plate 109; A first spring 110 is fixedly connected between the upper end of the first slide 7 and the top of the first slide groove 6 at the lower end, and the elastic force of the first spring 110 is greater than the friction resistance of the first slide 7 when sliding in the first slide groove 6. When the electric telescopic cylinder 108 is in a retracted state, the distance between the pressing plate 109 and the first slide 7 is greater than the width of the pad 107. When the electric telescopic cylinder 108 is in an extended state, the lower end of the pressing plate 109 is in contact with the first slide 7 but no squeezing force is generated. A reset assembly 12 is provided on the left portion of the base 1, and the reset assembly 12 includes a cushion seat 121 fixedly connected to the left sides of the front and rear ends of the base 1, the upper end of the cushion seat 121 is fixedly connected to a slide rod 122, the upper part of the slide rod 122 is slidably sleeved with a sleeve 123, the outside of the slide rod 122 is sleeved with a second spring 124 located between the sleeve 123 and the cushion seat 121, the upper end of the sleeve 123 is fixedly connected to a support rod 126, the lower end of the pad 107 is provided with an integrally formed slide rail 125, and the top end of the support rod 126 is slidably clamped to the outside of the slide rail 125.

[0023] By adopting the above technical solution, the formed aluminum die-casting is first placed on the conveying assembly 3, and the conveying assembly 3 is driven to rotate by the first driving motor 4 to realize the conveying of the aluminum die-casting. It should be noted that the conveying assembly 3 belongs to the prior art, so its detailed structure is not repeated here. As the aluminum die-casting is conveyed, when one end of the casting contacts the rotating plate 104, it will push the rotating plate 104 to rotate, and the rotation of the rotating plate 104 will drive the push plate 106 to move to the right through the driving shaft 105. When the push plate 106 moves to the right, it will push the pad 107 to between the pressure plate 109 and the first slide seat 7. Because the electric telescopic cylinder 108 is extended in the initial state, it is close to the first slide seat 7 but does not produce squeezing. Pressure, so when the pad 107 is pushed to the bottom of the pressure plate 109, the pressure plate 109 will push the first slide 7 downward through the pad 107, so that the first slide 7 drives the cutting disc 9 to move downward synchronously until the cutting disc 9 contacts the casting, and the second drive motor 8 drives the cutting disc 9 to rotate to cut the casting, thereby realizing the truncation of the casting. It should be noted that the casting drives the rotating plate 104 to rotate and then controls the truncation position of the casting by the cutting disc 9, ensuring that the spacing of each truncation is the same. After the casting is truncation, it falls naturally, and the subsequent workpieces are continuously conveyed to the bottom of the cutting disc 9 for truncation. The entire truncation process does not require human participation, and the truncation efficiency and accuracy are high. In addition, when the pad 107 moves to the right, the slide rail 125 at its lower end slides relative to the support rod 126, and when the pad 107 moves downward, the support rod 126 pushes the sleeve 123 to move downward synchronously along the surface of the slide rod 122. During the downward movement, the sleeve 123 squeezes the second spring 124, and after the casting is cut off and falls off, it no longer squeezes the turn plate 104. At this time, the turn plate 104 rotates and resets, and drives the pad 107 to move left and reset synchronously. At the same time, the second spring 124 is used to push the sleeve 123 upward, so that the pad 107 is reset to its original position, and so on.

[0024] like Figure 1 and Figure 3 As shown, an adjustment assembly 11 is provided between the driving shaft 105 and the push plate 106 and between the second support frame 101 and the rotating plate 104. The adjustment assembly 11 includes a second slide groove 102 opened on the upper part of the second support frame 101, and the second slide seat 103 is movably connected inside the second slide groove 102, and the second slide seat 103 is rotatably connected to the rotating plate 104. The interior of the pushing plate 106 is provided with fixing holes 111 in a linear array, and a cavity 113 is provided in the middle of the fixing holes 111. The end of the driving shaft 105 away from the rotating plate 104 is threadedly connected with a fixing nut 112; The friction resistance between the second slide seat 103 and the second slide groove 102 is greater than the force exerted on the rotating plate 104 when it rotates. After the rotating plate 104 rotates forty-five degrees clockwise, the pad 107 is pushed to the bottom of the pressure plate 109. A torsion spring 114 is movably connected between the drive shaft 105 and the push plate 106 and between the rotating plate 104 and the second slide seat 103. The torsion spring 114 is used to push the push plate 106 and the rotating plate 104 to return to the initial position after being cut off.

[0025] By adopting the above technical solution, the drive shaft 105 is inserted into the fixing hole 111 on the push plate 106 and fixed by the fixing nut 112, so as to realize the connection between the drive shaft 105 and the push plate 106. By inserting the drive shaft 105 into different fixing holes 111 for fixing, the pushing distance of the push plate 106 when the rotating plate 104 rotates can be changed. At the same time, the rotating plate 104 can also slide in the second slide groove 102 through the second slide seat 103, so as to adjust the distance between the rotating plate 104 and the transmission component 3, thereby realizing the adjustment of the casting cut-off distance, so that castings of different lengths can be cut off.

[0026] like Figure 1 and Figure 6 As shown, a stabilizing component 13 is provided at the upper end of the frame 2, and the stabilizing component 13 includes a third support frame 131 fixedly connected to the upper end of the frame 2, a pressure roller 132 is provided between the two third support frames 131, a third slide groove 133 is opened on the inner side of the third support frame 131, and a third slide seat 134 is slidably connected inside the third slide groove 133, a rotating roller 135 is rotatably connected between the two third slide seats 134, the pressure roller 132 is fixedly sleeved on the outside of the rotating roller 135, and a third spring 136 is fixedly connected between the upper end of the third slide seat 134 and the third slide groove 133.

[0027] By adopting the above technical scheme, when the casting is conveyed on the conveying assembly 3, it will be pressed down by the pressure roller 132. On the one hand, the position deviation of the casting during the conveying process can be reduced. On the other hand, after the casting contacts the rotating plate 104, the pressure roller 132 cooperates with the rotating plate 104 to form a simple positioning for the casting, so as to reduce the deviation of the casting when it is cut off, ensure the neatness of the cut end, and also avoid the warping of a certain section of the casting when it is cut off. When the thickness of the casting changes, an upward force will be applied to the pressure roller 132. At this time, the third slide seat 134 slides and rises inside the third slide groove 133, so as to achieve the role of stabilizing the pressure of castings of different specifications, and the third spring 136 serves the purpose of providing pressure for the pressure roller 132, and also facilitates the reset of the pressure roller 132.

[0028] like Figure 1 and Figure 5As shown, a cleaning assembly 14 is provided between the first slide groove 6 and the first slide seat 7 at the lower end, and the cleaning assembly 14 includes a telescopic air bag 141 fixedly connected between the lower end of the first slide seat 7 and the first slide groove 6, and a nozzle 142 is fixedly connected to the front and rear ends of the cutting disk 9 on the left side of the first slide seat 7, and a one-way valve is provided inside the nozzle 142, and the telescopic air bag 141 and the nozzle 142 are connected through a pipe fitting.

[0029] By adopting the above technical solution, when the first slide 7 moves downward, the telescopic airbag 141 will be squeezed. At this time, the gas inside the telescopic airbag 141 will be squeezed to the nozzle 142 and sprayed out, and then the debris generated during the truncation will be blown away by the airflow, so as to avoid the debris splashing on the conveying component 3 or the surface of the uncut casting and affecting the subsequent truncation operation, and further ensure that the truncation quality is not affected. It should be noted that a one-way valve is provided inside the nozzle 142 to ensure that the gas will only be sprayed out from the nozzle 142 and the nozzle 142 will not be used to inhale the external gas into it.

[0030] Method of use: First, place the formed aluminum die-casting on the conveying assembly 3, and drive the conveying assembly 3 to rotate through the first drive motor 4 to realize the conveying of the aluminum die-casting. As the aluminum die-casting is conveyed, when one end of the casting contacts the turn plate 104, it will push the turn plate 104 to rotate, and the rotation of the turn plate 104 will drive the push plate 106 to move to the right through the drive shaft 105. When the push plate 106 moves to the right, it will push the pad 107 to between the pressure plate 109 and the first slide 7. When the pad 107 moves to the right, the slide rail 125 and the support rod 126 at its lower end slide relative to each other. In the initial state, the electric telescopic cylinder 108 is extended and is in contact with the first slide 7 but does not generate extrusion force. Therefore, when the pad 107 is pushed below the pressure plate 109, the pressure plate 109 will push the first slide 7 downward through the pad 107, thereby using the first slide 7 to drive the cutting disk 9 to move downward synchronously. , and when the pad 107 moves down, the support rod 126 will push the sleeve 123 to move down synchronously along the surface of the slide rod 122. During the downward movement, the sleeve 123 squeezes the second spring 124 until the cutting disk 9 contacts the casting, and the second drive motor 8 drives the cutting disk 9 to rotate to cut the casting, thereby realizing the truncation of the casting. It should be noted that the casting pushes the rotating plate 104 to rotate and then controls the truncation position of the casting by the cutting disk 9, ensuring that the spacing of each truncation is the same. After the casting is cut off, it falls naturally, and the subsequent workpieces are continuously conveyed to the bottom of the cutting disk 9 for truncation. After the casting is cut off and falls, it no longer squeezes the rotating plate 104. At this time, the rotating plate 104 rotates and resets, and drives the pad 107 to move left and reset synchronously. At the same time, the second spring 124 is used to push the sleeve 123 up, so that the pad 107 is reset to its original position, and so on.

[0031] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
