Description

Technical Field

[0001] The invention relates to the technical field of manufacturing a middle trough of a scraper conveyor, and in particular to a manufacturing method of a middle trough of a full-protection scraper conveyor. Background Art

[0002] A fully protected scraper conveyor is a feeding device that uses a scraper chain to transport bulk materials in a trough. It is mainly composed of two mechanisms: a middle trough and a conveying scraper. Among them, the middle trough is mainly composed of two side guards and a middle main plate. When the middle trough is manufactured, two metal strips are generally stamped into side guards, and then the two side guards are welded to the main plate.

[0003] At present, the production of the middle trough of the scraper conveyor, the stamping of the side guard plate and the welding forming are two steps. From stamping to welding, it includes operations such as transfer and splicing, which will waste a lot of time. In addition, the welding part is basically done manually. This series of processes makes it impossible to improve the production efficiency of the middle trough of the scraper conveyor. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a method for manufacturing the middle trough of a fully protected scraper conveyor.

[0005] The present invention is implemented by the following technical solution: S1: prepare the metal plate original of the middle trough main plate and the metal plates original of the two side guard plates;

[0006] S2: Place the main body plate metal plate original and the two side guard plate metal plate originals into the middle groove manufacturing device;

[0007] S3: The middle groove making device stamps the two side guard plate metal plate originals into shape;

[0008] S4: The two stamped side guards and the main body metal plate are discharged together, and the three are welded into a whole during the discharge process. Finally, the middle groove production device discharges the completed middle groove;

[0009] The middle groove manufacturing device includes a base, a frame is fixedly installed on the top of the base, a lifting mechanism is provided on the frame, an outer frame is installed on the lifting mechanism, a fixed mold is fixedly installed in the outer frame, two hydraulic cylinders are fixedly installed on the inner walls of both sides of the outer frame, two clamping molds are slidably installed in the outer frame, the output rods of the four hydraulic cylinders are fixedly connected to the two clamping molds respectively, four welding guns are fixedly installed at the bottom of the fixed mold, and an ejector plate is provided on the frame;

[0010] As a further improvement of the above solution, an insertion slot is provided on the fixed mold.

[0011] Through the above technical solution, the insertion seam allows the main plate to be inserted into the fixed mold and maintain a stable shape with the side guard plate, thereby facilitating subsequent welding.

[0012] As a further improvement of the above solution, a frame body is fixedly mounted on the top inner wall of the frame, and the ejector plate is hinged to the frame body.

[0013] Through the above technical solution, the frame is connected to the ejector plate through a hinge joint, which allows the ejector plate to eject the side guard plate and the main plate when the fixed mold and the clamping mold rise, and can also be offset so that the main plate will not be restricted by the ejector plate when inserted into the insertion gap.

[0014] As a further improvement of the above scheme, the lifting mechanism includes a motor fixedly mounted on the top of the frame, two screws are rotatably mounted on the frame, the top ends of the corresponding screws are fixedly connected to the output shaft of the motor, and a first bevel gear is fixedly sleeved on both screws. A drive rod is rotatably mounted on the top inner wall of the frame, and a second bevel gear is fixedly mounted on both ends of the drive rod. The two first bevel gears are respectively engaged with the two second bevel gears, and a driving block is threadedly sleeved on the two screws, and the two driving blocks are fixedly connected to the outer frame.

[0015] Through the above technical solution, the lifting mechanism is mainly used to drive the fixed mold and the clamping mold to rise, so as to realize the separation of the fixed mold, the clamping mold, the side guard plate and the main plate.

[0016] As a further improvement of the above scheme, a sliding mechanism is provided on the outer frame and the two clamps. The sliding mechanism includes two support bars fixedly mounted on the outer frame, two sliding rods fixedly mounted on the two support bars, and the sliding sleeves on the two sliding rods are provided with the same connecting strip. One side of the connecting strip extends into the outer frame and is fixedly connected to the clamp.

[0017] Through the above technical solution, the sliding mechanism can ensure the stability of the clamping die without affecting the movement of the clamping die.

[0018] As a further improvement to the above solution, sliding openings are provided on the inner walls on both sides of the outer frame, and the connecting strips pass through the corresponding sliding openings and are slidably connected to the corresponding sliding openings.

[0020] As a further improvement of the above solution, two pads and a pad are fixedly installed on the top of the base.

[0021] Through the above technical solution, the pads and the pads can support the side guard plates and the main body plates, so that the two will not leak out from the bottom of the fixed mold and the clamping mold.

[0022] As a further improvement of the above solution, two long grooves are provided on both sides of the fixed mold, and magnet bars are embedded in the four long grooves.

[0023] Through the above technical solution, the magnet strips can allow the stamped edge guard plates to be adsorbed to both sides of the fixed mold, and the edge guard plates will not fall over or move due to the separation of the clamping mold, so that the edge guard plates can maintain a spliced ​​shape with the main plate to facilitate subsequent welding.

[0024] As a further improvement of the above-mentioned solution, two rotating holes are provided on the top inner wall of the frame, and the top ends of the two screws respectively pass through the corresponding rotating holes and are rotatably connected to the corresponding rotating holes. A plurality of support blocks are fixedly installed on the inner walls on both sides and the top inner wall of the frame, and the two screws and the driving rod respectively pass through the corresponding support blocks and are rotatably connected to the corresponding support blocks.

[0025] Through the above technical solution, the rotating hole and the support block mainly serve as support members for the screw rod and the driving rod, so that both can operate stably on the frame.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention cooperates with the outer frame, fixed die, hydraulic cylinder and clamping die to not only realize the stamping of the side guard plate of the middle trough of the scraper conveyor, but also can splice the stamped side guard plate with the main plate together to facilitate subsequent welding work.

[0028] Through the cooperation of the lifting mechanism, ejector plate and welding gun, the side guard plate and the main body plate can be automatically discharged, and the side guard plate and the main body plate that are spliced ​​together can be welded during the discharge process, making the production of the middle trough of the scraper conveyor more convenient and efficient.

[0060] The implementation principle of a method for manufacturing the middle trough of a fully protected scraper conveyor in the embodiment of the present application is as follows:

[0061] Step 1: When in use, place the two side guard plate metal plates between the fixed mold 10 and the two clamping molds 12, and then place the main body plate metal plate into the slot on the fixed mold 10;

[0062] Step 2: Start the four hydraulic cylinders 11, which respectively drive the two clamping dies 12 to move, thereby punching the two side guard plate metal sheets into M-shaped scraper conveyor middle trough side guard plates. Then, the two clamping dies 12 are reset. At this time, the two formed side guard plates are attracted to the two sides of the fixed die 10 by the influence of the magnet strips 21.

[0063] The third step: start the motor 3, and the motor 3 drives the corresponding screw 4 to rotate through the output shaft. Under the transmission of the drive rod 6, the first bevel gear 5 and the second bevel gear 7, the two screws 4 rotate synchronously, and then the two screws 4 drive the outer frame 9, the fixed mold 10 and the clamping mold 12 to rise through the two driving blocks 8.

During this process, start four welding guns 16, and the welding gun 16 can weld the contact points of the continuously ejected side guard plate and the main plate metal plate original. When the side guard plate and the main plate metal plate original are discharged from the fixed mold 10 and the clamping mold 12, the two are also welded, which makes the production of the middle trough of the scraper conveyor more convenient and efficient.
