Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automatic pipe conveying, in particular to a stamping conveying device. BACKGROUND

[0002] Stamping is a forming process that uses a press and a die to apply force to sheet metal, strip, pipe and profiled material, etc. to produce plastic deformation or separation, thereby obtaining the desired shape and size of the workpiece (stamping). Currently, pipe processing involves a transfer process, i.e. the pipe that has completed stamping is transferred to the next station for finishing, but the existing transfer method is mainly completed by manual labor, which is labor-intensive and low in efficiency.

[0003] To solve the above problems, the Chinese utility model patent with publication number CN104108584B discloses a pipe conveyor, which comprises a hopper, a feeding mechanism and a conveyor belt, the feeding mechanism comprises a feeding disc and an adjusting disc, and the conveyor belt is provided with an adjusting device for adjusting the horizontal position of the pipe; the patent uses a mechanical structure to replace manual labor to transport the pipe, thereby reducing the labor intensity and improving the work efficiency.

[0004] When using the above patent to transport the pipe after stamping, the surface of the pipe will be covered with a lot of debris due to the stamping process, but the above patent does not have a structure for cleaning the surface of the pipe, so the pipe needs to be cleaned separately when transported to the next station, which prolongs the processing time and reduces the work efficiency. SUMMARY

[0005] The present application aims to provide a stamping conveying device to solve the problem that the existing pipe conveying device does not have a cleaning function when conveying the pipe after stamping.

[0006] To achieve the above purpose, the present application adopts the following technical scheme: a stamping conveying device, comprising a machine base, a stay plate, a fixed plate and a conveying plate are sequentially arranged on the machine base from left to right, a sliding block is slidably connected to the fixed plate, a clamping mechanism for clamping the pipe on the stay plate is arranged on the sliding block, the conveying plate is inclined, and the conveying plate and the stay plate are located below the fixed plate; a water spraying mechanism is arranged on the machine base and located below the fixed plate; a chamber is arranged in the machine base, a plurality of recovery holes for recovering the water sprayed by the water spraying mechanism are arranged on the machine base, and the recovery holes are communicated with the chamber; and a driving part for driving the sliding block to slide is further included.

[0007] The principle and advantages of the present application are as follows:

[0008] 1. This solution uses a clamping mechanism to clamp the pipe on the holding plate, and then a drive unit moves the slider towards the conveyor plate, which in turn moves the pipe towards the conveyor plate. During the pipe's movement, a water spraying mechanism cleans the pipe and removes debris. After cleaning, when the pipe moves above the conveyor plate, the clamping mechanism stops clamping, causing the pipe to fall onto the conveyor plate, which then transports it to the next processing station. Compared to existing technologies, this solution allows for comprehensive cleaning of the stamped pipe during transport to the next workstation, reducing the need for separate cleaning processes, thus shortening processing time and effectively improving work efficiency.

[0009] 2. In this solution, the mixture of water and waste that falls after cleaning the pipes is collected in the chamber through the through hole, thereby improving the cleanliness of the working environment.

[0010] Furthermore, the clamping mechanism includes two base plates fixed to the slider, with a bidirectional screw rotatably connected to each base plate, and movable blocks threaded to both ends of the bidirectional screw; it also includes a power unit for driving the bidirectional screw to rotate.

[0011] With the above setup, the power unit drives the bidirectional screw to rotate, causing the two moving blocks to move closer or further apart, thereby clamping and releasing the pipe.

[0012] Furthermore, a cylinder is rotatably connected to the movable block, and a limiting groove for limiting the end of the pipe is provided on the cylinder. A first gear is provided on the cylinder. Both sides of the machine base surface are provided with a first rack for meshing with the first gear, and the first rack is located on the movement trajectory of the first gear.

[0013] With the above configuration, the power unit drives the bidirectional screw to rotate, bringing the two movable blocks closer together, which in turn brings the two cylinders closer together. This causes both ends of the pipe to extend into the limiting grooves on both sides, and the two ends of the pipe to abut against the limiting grooves on both sides, thereby clamping the pipe and strengthening the limiting effect to prevent the pipe from shifting or falling off. While the slider moves the pipe laterally, the cylinder also moves laterally. The first gear on the cylinder meshes with the first rack, causing the cylinder to drive the pipe to rotate continuously. The rotating pipe is cleaned by a water spray mechanism, which can clean the pipe more thoroughly and achieve better cleaning results.

[0014] Further, the water spraying mechanism comprises a manifold, a water pump, a water inlet pipe and a plurality of water spraying units, the manifold is fixedly connected with the chamber, each water spraying unit comprises an outer pipe and an inner pipe, the outer pipe is in communication with the manifold, the inner pipe is rotatably connected with the inner wall of the outer pipe and in communication with the outer pipe, the inner pipe is connected with the base, the top of the inner pipe is provided with a first water spraying hole, the water pump is fixedly connected in the chamber, the water pump is in communication with the manifold and the water inlet pipe respectively, the water inlet pipe extends out of the base, the side wall of the base is provided with a side hole in communication with the chamber, and a sealing block for sealing the side hole is detachably connected to the base.

[0045] The second cylinder is started, the output shaft of the second cylinder drives the sliding block 30 to move transversely to the direction of the stay plate 11, so that the single pipe is located between the two movable blocks 33, and the second cylinder is closed; the motor is started, the output shaft of the motor drives the bidirectional screw rod 32 to rotate, so that the two movable blocks 33 are close, and then the two cylinders 34 are close; when the two ends of the pipe respectively extend into the limiting grooves 341 on both sides, and the two ends of the pipe respectively abut against the limiting grooves 341 on both sides, the motor is closed, so as to realize the positioning of the two movable blocks 33, and then realize the positioning of the two cylinders 34, that is, realize the clamping of the pipe.

[0046] The second cylinder and the water pump 43 are restarted, the output shaft of the second cylinder drives the sliding block 30 to slide transversely to the direction of the conveying plate 13, and then drives the pipe to move to the direction of the conveying plate 13; during the transverse movement of the sliding block 30, the cylindrical column 34 also moves transversely, the first gear 342 on the cylindrical column 34 is engaged with the first rack 35, so that the cylindrical column 34 drives the pipe to continue to rotate; the water pump 43 introduces the external clean water through the water inlet pipe 44, so that the clean water is transmitted to the inner pipe 51 through the main pipe 42 and the outer pipe 50, and is sprayed out through the first water spraying hole 52 and the second water spraying hole 53 in the inner pipe 51; during the transverse movement of the pipe, the water sprayed out of the first water spraying hole 52 and the second water spraying hole 53 acts on the rotating pipe, which can more comprehensively clean the pipe; and the water spraying part and the water spraying unit are both multiple, which prolongs the cleaning path of the pipe and increases the cleaning range of the pipe, that is, strengthens the cleaning effect of the pipe; in addition, during the transverse movement of the pipe, the first brush layer 74 can clean the pipe, thereby strengthening the cleaning effect of the pipe; the mixture of water and waste falling after cleaning the pipe is collected into the cavity 40 through the through hole.

[0047] During the transverse movement of the sliding block 30, the sliding block 30 also drives the second rack 62 to move transversely, the second rack 62 is engaged with the second gear 63, so that the single inner pipe 51 rotates, and then all the inner pipes 51 of the single water spraying unit are driven to rotate through the action of the first sprocket 61 and the first chain 60; during the rotation of the inner pipe 51, since the second water spraying hole 53 is inclinedly arranged, the water sprayed out of the second water spraying hole 53 can be sprayed farther under the action of centrifugal force, thereby increasing the number of times that the water sprayed out of the second water spraying hole 53 acts on the pipe, thereby strengthening the cleaning effect of the pipe; during the transverse movement of the second rack 62, the second rack 62 also engages with the third gear 73, so that the single rotating shaft 71 rotates, and then all the rotating shafts 71 of the single cleaning part are driven to rotate through the action of the second sprocket 72 and the second chain 70; during the rotation of the rotating shaft 71, the rotating shaft 71 drives the multiple first brush layers 74 and the multiple second brush layers 75 to rotate, the rotation of the multiple first brush layers 74 can increase the number of times of cleaning the pipe, thereby strengthening the cleaning effect of the pipe; the rotation of the multiple second brush layers 75 can clean the surface of the machine base 10, so that the mixture of water and waste falling after cleaning the pipe does not block the through hole, thereby ensuring the recycling of water and waste.
