Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of differential pressure casting, in particular to a differential pressure casting integrated transfer trolley. BACKGROUND

[0002] During the production of the differential pressure casting machine, the differential pressure machine crucible furnace and the differential pressure mold need to be frequently replaced. The original production line uses a common aluminum replacement trolley to replace the crucible furnace, and a forklift to replace the mold. The overall efficiency is low, which affects the automatic operation of the whole line, and the long time of mold replacement leads to a large loss of hot mold temperature, resulting in an increase in waste products, affecting the rhythm, and increasing the cost. At the same time, the working site is high temperature and dusty, the environment is harsh, the forklift installs the mold, which is unstable, and there is a risk of squeezing the operator, which has a great impact on the physical and mental health of the workers. The present application discloses a differential pressure casting integrated transfer trolley, which integrates the functions of replacing the crucible furnace and the mold, and both are double stations. The process of replacing the crucible furnace is stable, ensures that the aluminum liquid does not shake, and is fast and efficient. The mold replacement mechanism adopts a set of driving mechanism, a progressive pushing and extending track and a mold replacement trolley mode, realizes the secondary forward and backward movement of the mold replacement device, and the mold replacement process is fast and efficient, safe and stable. It reduces the time and energy of the on-site workers, reduces the temperature loss of the mold, improves the production efficiency, and provides a powerful equipment guarantee for the differential pressure casting whole line to reduce cost and increase efficiency, energy saving and emission reduction. SUMMARY

[0003] Therefore, the present application aims to provide a differential pressure casting integrated transfer trolley, which provides strong support for the differential pressure casting production line, improves the production efficiency through the upgrading of the equipment, improves the product quality, and greatly reduces the workload of the on-site personnel and the labor intensity. The integrated transfer trolley has stable structure, convenient and safe operation, and provides a powerful guarantee for realizing the few-person differential pressure casting production and automation.

[0004] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

[0005] The differential pressure casting integrated transfer vehicle comprises a frame platform mechanism, a whole vehicle walking mechanism, a positioning mechanism, a push-pull crucible furnace mechanism, a double-station connecting mechanism, a push-pull mold mechanism, an extension guide rail mechanism, a mold changing trolley mechanism, and an integrated vehicle differential pressure machine docking part. The frame platform mechanism is a whole platform frame mechanism and a two-layer mold changing platform mechanism, which is built by channel steel square tubes and the like. The whole vehicle walking mechanism is fixed on the frame platform mechanism, so that the whole vehicle runs stably on the track. The positioning mechanism is fixed on the whole vehicle walking mechanism, and functions as positioning the trolley and the differential pressure machine when the crucible furnace and the mold are changed. The push-pull crucible furnace mechanism is fixed on the whole vehicle walking mechanism, so as to ensure stable pushing and pulling of the crucible furnace. The double-station connecting mechanism is welded and fixed after adjusting the horizontal position of the left and right stations of the whole vehicle, so as to ensure stable connection of the two parts and a certain clearance. The push-pull mold mechanism is fixed on the two-layer platform. The extension guide rail mechanism is fixed on the two sides of the two-layer platform. The mold changing trolley mechanism is arranged on the track of the extension guide rail mechanism.

[0006] In some embodiments, the frame platform mechanism comprises a whole base frame and a two-layer platform.

[0007] In some embodiments, the power output of the whole vehicle walking mechanism is a walking reduction motor, which transmits power to the driving flat wheel part through the driving sprocket and the driven sprocket. The driving sprocket part plays a guiding role. The auxiliary wheel shaft part is a follower wheel group. The whole wheel group mechanism is connected to the integrated vehicle frame through the bearing part with a seat. The safety limiting mechanism is arranged on both sides of the integrated vehicle, and comprises a guard plate, a spring, a limiting switch, and an elastic colloid buffer. The upper part has a precise crucible furnace walking track. The integrated vehicle runs stably on the whole vehicle walking track. The rotation speed of the power device walking reduction motor can be set in real time through the display screen, so as to realize the setting of the running speed.

[0008] In some embodiments, the power output of the positioning mechanism is a positioning reduction motor, which transmits power to the driving sprocket mechanism through the small sprocket mechanism. The driving sprocket mechanism and the driving chain wheel mechanism are installed on the same rotating shaft, and then the chain is connected to the follower sprocket mechanism. The driving chain wheel mechanism drives the positioning mechanism to move forward and backward. The chain tensioning mechanism ensures that the chain is adjusted properly and runs stably. The connecting seat plate is connected to the chain. The positioning head device runs stably on the fixed guide rail through the positioning roller bearing fixed on the connecting seat plate. The front and rear stop positions of the positioning mechanism are detected by the front positioning stop position detection switch and the rear stop position detection switch of the positioning mechanism, and the positioning switch detection column fixed on the connecting seat plate. The positioning roller bearing at the front end of the positioning head is pushed into the integrated vehicle positioning block, so as to play a role in adjusting and positioning the integrated vehicle and precisely docking with the differential pressure machine.

[0009] In some embodiments, the power output of the push-pull crucible furnace mechanism is composed of a push-pull furnace deceleration motor, a push-pull small chain wheel mechanism, a push-pull large chain wheel mechanism, a push-pull drive chain wheel mechanism, and a push-pull follow-up chain wheel mechanism, which are fixed on the push-pull mechanism frame. The push-pull head device is stably operated on the push-pull fixed guide rail through the fixed needle bearing mechanism on the connecting seat plate. The furnace body is smoothly pulled out through the pull furnace mechanism, and the furnace body is stably pushed forward through the push furnace mechanism. The deceleration stop function in the push-pull process is realized through the push-pull furnace front deceleration position detection switch, the push-pull furnace front stop position detection switch, the push-pull furnace rear deceleration position detection switch, and the push-pull furnace rear stop position detection switch.

[0010] In some embodiments, the double-station connecting mechanism connects the two parts of the left and right double-station vehicles through the connecting shaft and the connecting plates B and C. The bottom plate is welded on both sides of the vehicle, and the connecting plates are fixed through the pressing plate.

[0011] In some embodiments, the power output of the push-pull mold mechanism is driven by a push-pull mold deceleration motor with a small pulley and a large pulley. The driving sprocket mechanism is connected to the large pulley through the push-pull mold driving shaft, and the follow-up sprocket mechanism is connected to the driving sprocket mechanism through the double-row chain. The whole mechanism is fixed on the push-pull mechanism frame through the belt seat bearing. The tension of the chain connected by the follow-up shaft through the jack mechanism can be adjusted to ensure stable operation. The telescopic guide rail limit pin is a fixed limit telescopic guide rail mechanism, and the mold changer trolley limit pin is a fixed limit mold changer trolley mechanism. The driving clamping block that drives the telescopic guide rail mechanism and the mold changer trolley mechanism is fixed on the double-row chain, and reciprocates with the operation of the chain. When it is extended, the action sequence is: the driving clamping block first drives the telescopic guide rail mechanism to move forward, and after the telescopic guide rail front position detection switch detects the position, the telescopic guide rail mechanism stops. The driving clamping block continues to run with the chain, and after rotating back, it drives the mold changer trolley mechanism to extend forward.

[0012] In some embodiments, the telescopic guide rail mechanism is positioned with the telescopic guide rail support mechanism on the differential pressure machine. The guide wheel group mechanism is fixed on the two side rails, and the driving clamping block on the chain enters the guide rail mechanism driving clamping groove, which is the power input part of the telescopic guide rail mechanism. The telescopic guide rail mechanism is detected by the telescopic guide rail front position detection switch and the telescopic guide rail rear position detection switch to detect the telescopic guide rail detection block, thereby achieving the function of deceleration and stop.

[0013] In some embodiments, the mold changer trolley mechanism places the differential pressure mold device thereon, and the mold guide key plays a role in positioning the mold. The driving clamping block on the chain enters the trolley mechanism driving clamping groove, which is the power input part. The push-pull support and the mold support plate are connected, and the whole mechanism roller support and roller mechanism make it run smoothly on the guide rail. The mold changer trolley mechanism is detected by the mold changer trolley front position detection switch and the mold changer trolley rear position detection switch to detect the mold changer trolley detection block, thereby achieving the function of deceleration and stop.

[0014] Compared with the prior art, the differential pressure casting integrated transfer vehicle has the following advantages:

[0015] 1. The double-station furnace changing and double-station mold changing ensure overall furnace changing and mold changing efficiency, and save time.

[0016] 2. After the push-pull mold mechanism drives the telescopic guide rail mechanism to the position through the driving block on the chain, the driving block returns on the chain to continue driving the mold trolley mechanism to run. This mechanism can realize twice forward movement and twice backward movement of the mold changing device. The mold pushing process is as follows: the driving block on the chain enters the telescopic guide rail driving slot, drives the telescopic guide rail to move forward, and after the telescopic guide rail is in place, the driving block continues to run with the chain, turns back, and then the driving block enters the driving slot on the mold trolley, drives the mold trolley to move forward until it is in the differential pressure machine. The return sequence is opposite. The overall structure is compact, the guide rail body is on the integrated vehicle, does not occupy the internal space of the differential pressure machine, can adapt to multiple types of differential pressure machines, is more flexible, and is stable in operation.

[0017] 3. The high rigidity and high precision positioning of the positioning mechanism and the differential pressure machine body, and the telescopic guide rail supporting mechanism ensure the accurate positioning of the telescopic guide rail, so that the mold changing trolley accurately enters, ensures accurate positioning of the mold, efficient installation, and reduces personnel operation time.

[0018] 4. The furnace body in-out and mold in-out operation adopts a remote control form, which ensures the convenience and safety of personnel operation, has a better observation line of sight, clearly shows the equipment state, and has a certain guarantee for the safety of personnel and equipment. At the same time, it can realize differential pressure lineless unmanned and automatic upgrading in the later period. BRIEF DESCRIPTION OF DRAWINGS
