Description

Technical Field

[0001] The invention relates to the technical field of chip transportation, and in particular to a speed-adjustable hydraulic chip transportation device and method. Background Art

[0002] In metal cutting processing, the hydraulic system plays a key role. It provides the necessary power and pressure to enable the cutting tool to cut according to the predetermined trajectory and depth, thereby generating a large number of chips. These chips often have coolant attached to the surface. This is because in wet processing, coolant is used to cool the cutting tool and the workpiece, and it also helps to lubricate and clean the cutting area. However, if these metal waste chips containing coolant are not cleaned and transported in time, they will not only take up a lot of working space, but may also have adverse effects on the processing equipment and the environment. Therefore, a transportation device is needed to transport the metal waste chips with coolant attached to the surface to the designated location.

[0003] A composite plate chain conveyor device for chip removal machine processing disclosed in the patent application with reference publication number CN216944950U isolates waste chips inside the composite plate chain conveyor device through a baffle, which can effectively prevent waste chips and dust from posing a threat to the health of operators. The discharge height of the composite plate chain conveyor device is lowered by a protective elastic hose to reduce the falling range of waste chips, thereby ensuring that all waste chips fall into the trash can, thereby reducing the workload of operators.

[0004] Comprehensive analysis of the above reference patents shows the following defects:

Under the action of the lower shaft, the lower sprocket, the upper shaft, the upper sprocket, the chain and the guide sprocket, the two chains are driven to drive a plurality of chip transport box mechanisms to move synchronously. Since a controller is provided at the bottom of the shell, the electromagnetic valve on the feed hopper is controlled by the controller to open and close regularly.

Beneficial Effects

[0023] The present invention provides a speed-adjustable hydraulic chip transport device and method. Compared with the prior art, it has the following beneficial effects:

[0024] 1. A speed-adjustable hydraulic chip transport device and method, through the cooperation between a chip transport box mechanism, an extrusion mechanism, an inclined guide tube and a trapezoidal top block, in the process of transporting the chip transport box mechanism containing metal waste chips toward the chip discharge pipe, when the chip transport box mechanism passes between two extrusion mechanisms, under the cooperation of the two extrusion mechanisms, the chip transport box mechanism can be driven to complete the multi-stage compression operation of the metal waste chips inside, effectively compressing the fluffy metal waste chips into blocks, saving subsequent storage space, and at the same time, the coolant attached to the surface of the metal waste chips can be squeezed out, which is convenient for subsequent processing and recycling.

[0025] 2. A speed-adjustable hydraulic chip transport device and method, through the cooperation between the accommodating box, the side push plate, the ball, the first spring and the extrusion protrusion, since the two side walls of the extrusion protrusion are inclined, when the chip transport box mechanism is transported between the two extrusion mechanisms, the two balls on the chip transport box mechanism will be pushed simultaneously by the extrusion protrusions at the front and rear two relative positions, so that the two balls are close to each other, and the two side push plates are close to each other accordingly. Under the elastic action of the first spring, when the ball does not contact the side wall of the extrusion protrusion, the two balls return to their original positions, and the two The side push plates then return to their original positions, and the metal scraps in the storage box can be compressed in a timely and automatic manner during transportation. Since a plurality of extrusion protrusions are provided, and the distance between the extrusion protrusions at the front and rear relative positions gradually decreases from right to left, the extrusion protrusions at the front and rear relative positions form a group. Therefore, in the process of transporting the chip transport box containing the metal scraps to the left, the extrusion force of the multiple groups of extrusion protrusions on the metal scraps in the storage box gradually increases from right to left, so that the fluffy metal scraps are gradually compressed evenly and effectively, thereby ensuring the stability of the compression process.

[0026] 3. A speed-adjustable hydraulic chip transport device and method, which transports the chip transport box mechanism toward the chip discharge pipe through the cooperation among the filtrate mesh plate, the liquid collecting bucket, the short tube, the blocking block, the trapezoidal bottom block, the second spring and the trapezoidal top block. During the process, the inclined surface of the trapezoidal bottom block will contact the inclined surface of the trapezoidal top block. Under the action of the trapezoidal top block, the trapezoidal bottom block moves to the left while being pushed upward by the trapezoidal top block, so that the trapezoidal bottom block slides upward along the inclined surface of the trapezoidal top block, thereby lifting the trapezoidal bottom block upward and causing the blocking block to move up and out of the short tube, so that the coolant collected in the liquid collecting bucket automatically flows downward through the short tube, thereby achieving the purpose of timely and automatic separation of the coolant during transportation.

[0027] 4. A speed-adjustable hydraulic chip transport device and method, through the cooperation between the placement box, the extrusion protrusion, the positioning hole and the bolt, can flexibly and accurately adjust the distance between the extrusion protrusions at the front and rear relative positions according to the required compression tightness of the metal waste, thereby changing the distance that the two spheres can move relative to each other, that is, changing the distance that the two side push plates can move relative to each other, thereby realizing the adjustment of the compression force of the metal waste, and having a wide range of applications.

Since a controller is provided at the bottom of the housing (1), the solenoid valve on the feed hopper (16) is controlled by the controller to open and close at a fixed time. The time of the fixed opening and closing is adapted to the operation law of the plurality of chip transport box mechanisms (8). That is, when each chip transport box mechanism (8) runs to the bottom of the feed hopper (16), the solenoid valve is opened and kept open for a preset time.

2. A speed-adjustable hydraulic chip transport method, characterized in that: Using the adjustable speed hydraulic chip transport device as claimed in claim 1, the method comprises the following steps: Step 1: Start the servo motor to drive the corresponding upper shaft to rotate. Under the action of the lower shaft, the lower sprocket, the upper shaft, the upper sprocket, the chain and the guide sprocket, the two chains are driven to drive a plurality of chip transport box mechanisms to move synchronously. Since a controller is provided at the bottom of the shell, the electromagnetic valve on the feed hopper is controlled by the controller to open and close regularly. The timing of the opening and closing is adapted to the operation law of the plurality of chip transport box mechanisms, that is, when each chip transport box mechanism runs to the right below the feed hopper, the electromagnetic valve is opened and kept open for a preset time. Step 2, when one of the chip transport box mechanisms moves to the bottom of the feed hopper, the solenoid valve opens, wherein the feed hopper is pre-placed with metal waste formed by hydraulic cutting, and part of the metal waste in the feed hopper automatically falls into the chip transport box mechanism directly below, and when the opening at the top of the chip transport box mechanism and the chip discharge opening at the bottom of the feed hopper are just misaligned, the solenoid valve closes, and then the chip transport box mechanism containing the metal waste continues to move toward the chip discharge pipe driven by the chain. During the process, when the chip transport box mechanism passes between the two extrusion mechanisms, under the action of the two extrusion mechanisms, the chip transport box mechanism is driven to complete the multi-stage compression operation of the metal waste inside, compressing the fluffy metal waste into blocks, and at the same time squeezing out the coolant attached to the surface of the metal waste, and the squeezed coolant flows to the bottom of the inner cavity of the chip transport box mechanism under the action of its own gravity; Step three, when the bottom of the chip transport box mechanism contacts the inclined surface of the trapezoidal top block, the bottom of the chip transport box mechanism is opened under the action of the trapezoidal top block so that the coolant automatically flows downward from the chip transport box mechanism, and finally the coolant flows to the outside along the inclined guide pipe and the liquid guide hose for unified collection, and then driven by the chain, the chip transport box mechanism is transported to the far left, and then begins to flip, so that the metal waste chips compressed into blocks in the chip transport box mechanism automatically fall under the action of their own gravity, and are discharged along the chip discharge pipe, completing the transportation of the metal waste chips.
