Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary frame production equipment, in particular to an auxiliary frame casting line. Background Art

[0002] The subframe can be regarded as the skeleton of the front and rear axles, and is a component of the front and rear axles. The subframe is not a complete frame, but a bracket that supports the front and rear axles and suspension, so that the axles and suspension are connected to the "main frame" through it, and it is customarily called the "subframe". The function of the subframe is to block vibration and noise and reduce their direct entry into the car compartment, so it mostly appears in luxury cars and off-road vehicles, and some cars also install subframes for the engine. The traditional load-bearing body without a subframe has its suspension directly connected to the body steel plate. Therefore, the suspension rocker arm mechanism of the front and rear axles are all loose parts, not assemblies. After the birth of the subframe, the front and rear suspensions can be assembled on the subframe first to form an axle assembly, and then this assembly can be installed on the body together.

[0003] The existing aluminum alloy subframe production generally goes through core setting, casting, transmission, sand shock and other cutting processes. In the process, the sand core is placed in the casting mold, and after the casting is cooled, the sand core is shaken off to complete the integrated cast aluminum production. However, it is often difficult to clean the sand core during the sand shock process, and subsequent cleaning is required. In addition, grabbing the cast subframe during the transportation process is also prone to damage. Therefore, we proposed a subframe casting line. Utility Model Content

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] The subframe casting lines provided by some embodiments of the utility model are described below in conjunction with the accompanying drawings.

[0023] Combination Figure 1-2As shown, the sub-frame casting line provided by the utility model comprises: a conveying assembly 100, a casting assembly 200, a casting device 300 and a cleaning assembly 400; wherein, the conveying assembly 100 comprises an overhead crane 110 and an electric threaded joint 120 suspended below the overhead crane 110, and the conveying assembly 100 is arranged above the casting assembly 200, the casting device 300 and the cleaning assembly 400 which are sequentially arranged, and is used for the transfer of the sub-frame;

[0024] The casting assembly 200 includes a casting box 210, a cooling system 220 disposed in the casting box 210, a cover plate 230 mounted on the top of the casting box 210, an electric threaded joint 240 mounted on the cover plate 230, a suspension rod 250 threadedly connected to the electric threaded joint 240, an opening 260 provided on the suspension rod 250, a patch 270 attached to the suspension rod 250 and located outside the opening 260, a side connecting rod 280 connected to the suspension rod 250, and a sand core 290 fixed to the outside of the suspension rod 250, so that the electric threaded joint 120 can be docked with the suspension rod 250, and then the cooled sand core and the product can be lifted up completely, so as to facilitate the contactless transportation of the product, and the suspension rod 250 can be prefabricated in the sand core without affecting the normal use of the sand core, which is more reasonable;

[0025] The casting equipment 300 is connected to the cover plate 230 by a pipeline; the cleaning assembly 400 includes a sand tremor box 410, a cleaning chamber 420 opened in the sand tremor box 410, a sand discharge pipe 430 connected to the bottom of the cleaning chamber 420, a drainage pipe 440 connected to the sand discharge pipe 430, a lifter 450 installed on the sand tremor box 410, a vibrator 460 fixed to the driving end of the lifter 450, a hanging pipe 470 connected to the bottom of the vibrator 460, an electric threaded joint 480 fixed to the bottom of the hanging pipe 470 for docking the hanging rod 250, and a pipe connected to the hanging pipe 470 and located in the sand tremor box 4 The water tank 490 on the side 10 can prefabricate the hanger 250 in the sand core through the conveying component 100, the casting component 200, the casting equipment 300 and the cleaning component 400, and can be lifted by the hanger 250 after casting, and can be transported without contacting the sub-frame. During the sand shaking, the hanger 250 can be connected to the vibrator 460, and the vibration is transmitted to the sand core by the hanger 250 to accelerate the initial separation of the sand core, and then the vibrator 460 contacts the sub-frame for deep cleaning. After the deep sand shaking cleaning, the water tank 490 is used to spray clean water from the opening 260 to complete further cleaning. This solution is convenient for both product transfer and sand core cleaning.

[0026] Specifically, a threaded ring 251 is fixed on the suspension rod 250, which facilitates the automated docking of the electric threaded connector 120, the electric threaded connector 240 and the electric threaded connector 3 480, making it more efficient and quick to use.

[0027] Furthermore, the opening 260 is a trumpet-shaped structure with a small opening facing outward, which can make the subsequent water source spray out with a higher pressure and facilitate cleaning.

[0028] On the other hand, the side connecting rod 280 is arranged to be inclined toward the middle of the sand core 290, which can increase the connection strength with the sand core and facilitate the subsequent spraying of cleaning water to clean the sub-frame more comprehensively.

[0029] It should be noted that a hydraulic rod 411 is provided in the sand jar box 410 , and a clamping block 412 is fixed to the driving end of the sand jar box 410 , which can preliminarily fix the sub-frame during sand jarring to prevent the sub-frame from falling and being damaged.

[0030] Furthermore, a movable base 451 is provided at the bottom of the lifter 450 to facilitate the movement of the lifter 450 so that the product can fall from directly above.

[0031] The working principle and use process of the utility model are as follows: first, the sand core is hoisted into the casting box 210 by the crane 110 in cooperation with the electric threaded joint 120, and then the cover plate 230 is covered, and the hanging rod 250 is connected by the electric threaded joint 240 to fix the sand core, and then the aluminum liquid in the casting equipment 300 is injected into the casting box 210 for casting. After the casting is completed, the cooling system 220 starts to cool. After cooling, the crane 110 hoists the sub-frame into the cleaning chamber 420, and then cooperates with the electric threaded joint 3 480 to connect to the hanging rod 250, and the sand core is shaken. During operation, the vibration generated by the vibrator 460 is transmitted to the hanger 250 through the hanging pipe 470, shaking the sand core off, and at the same time, the sub-frame is fixed by the clamping block 412, and then the vibration component on the vibrator 460 falls and contacts the sub-frame for deep sand shaking. After the sand shaking is completed, the water source in the water tank 490 enters the hanger 250 through the hanging pipe 470, and then sprays out from the opening 260, and the patch 270 is pushed off to clean the sub-frame. The sand and sewage are discharged through the sand discharge pipe 430 and the drain pipe 440. After cleaning, the subsequent cutting and grinding process continues.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
