Description

Technical Field

[0001] This utility model belongs to the field of copper pipe processing technology, and specifically relates to an automatic marking device for copper pipes. Background Technology

[0002] Currently, some copper piping products require raised dots for welding positioning. The distance between these positioning points and the product port is 20mm. For ordinary products, the distance between the positioning points and the product port is 5-10mm, which is easy to achieve with traditional automatic marking machines for material return and automated production. However, for this product, the distance between the positioning points and the port is 20mm, which is not easy to achieve with traditional automatic marking equipment. It can only be produced manually on a semi-automatic marking machine, resulting in high manual marking costs.

[0003] Therefore, it is necessary to propose an automatic marking device for copper piping to solve the above problems. Utility Model Content

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0033] like Figures 1-9 As shown in the figure, this utility model embodiment specifically provides an automatic marking device for copper piping, including:

[0034] Rack 1;

[0035] The feeding mechanism 2 is installed at an angle on the frame 1 and is used to automatically feed copper pipes to the pushing station.

[0036] The pushing mechanism 3 is installed on the frame 1 and is used to feed the copper pipe at the pushing station to the dotting station seat 4.

[0037] The dotting mechanism 5 includes: a telescopic module 51, a pressing module 52, and a dotting needle 53; the telescopic module 51 is mounted on the frame 1 and is used to control the dotting needle 53 to move laterally; the pressing module 52 is mounted on the frame 1 and is used to control the dotting needle 53 to move longitudinally.

[0038] The unloading mechanism 6 is installed on the marking station seat 4 and is used to automatically unload the marked copper pipes into the receiving frame 7.

[0039] When marking the copper pipe, the marking needle 53 waits 20mm from the end of the copper pipe. When the pushing cylinder 31 pushes the copper pipe onto the marking station seat 4, the copper pipe automatically fits onto the marking needle 53. At this time, the pressing module 52 can be controlled to press down, thereby driving the marking needle 53 to make markings. After marking is completed, the telescopic cylinder 511 is controlled to shorten and retract the connecting rod 513, thereby disengaging the marking needle 53 from the copper pipe. At this time, the unloading mechanism 6 can be controlled to unload the material.

[0040] The feeding mechanism 2 includes: a hopper 21, an adjusting plate 22, a pushing station slot 23, a cover plate 24, a feeding cylinder 25, and a feeding plate 26. The hopper 21 is installed at an angle on the frame 1. The adjusting plate 22 is adjustablely installed inside the hopper 21. The pushing station slot 23 is opened at the lower end of the hopper 21. The cover plate 24 is fastened to the pushing station slot 23. The feeding cylinder 25 is installed on the cover plate 24. The driving end of the feeding cylinder 25 is equipped with the feeding plate 26. The hopper 21 is made of aluminum plate to reduce the overall weight. At the same time, because aluminum is relatively soft, it can reduce the impact damage to the copper material. The hopper is tilted at 20° to allow the product to fall into the area to be pushed using its own weight. The hopper is designed to adjust the position of the adjustment plate 22 to accommodate the production of copper pipes of different lengths for marking. At the same time, in order to prevent the discharge of materials from being pushed, a material-pushing cylinder 25 is installed in the hopper, which pushes the material-pushing plate 26 to push the material.

[0041] The pushing mechanism 3 includes a pushing cylinder 31 and a pushing rod 32; the driving end of the pushing cylinder 31 is provided with the pushing rod 32. Through the extension action of the pushing cylinder 31, the pushing rod 32 is driven to push the copper pipe at the pushing station to the marking station seat 4 for subsequent marking action.

[0042] It also includes a connecting seat 33 and a spring 34. The driving end of the pusher cylinder 31 also includes a connecting seat 33. The connecting seat 33 has a slot with a spring 34 inside. The other end of the spring 34 is connected to the end of the pusher rod 32, and the pusher rod 32 is slidably engaged in the connecting seat 33. With the above-mentioned setting of the spring 34, an elastic buffer force can be formed when the copper pipe and the dotting needle 53 are inserted to protect the copper pipe.

[0043] The telescopic module 51 includes a telescopic cylinder 511, a connecting block 512, and a connecting rod 513. The driving end of the telescopic cylinder 511 is provided with the connecting block 512, and the connecting rod 513 is slidably engaged within the connecting block 512. A dotting pin 53 is detachably locked to the end of the connecting rod 513. By controlling the movement of the telescopic cylinder 511, the dotting pin 53 can be moved to the dotting position and retracted into the insertion hole 525 of the lower pressure seat 524 via the connecting rod 513.

[0044] The connecting block 512 also includes a T-shaped groove 514, and the end of the connecting rod 513 is slidably engaged with the T-shaped groove 514. The connection block 512 and the connecting rod 513 ensure that the pressing cylinder 521 has sufficient space to slide up and down when pressing the dotting needle 53, thus avoiding motion interference.

[0045] The pressing module 52 includes: a pressing cylinder 521, a linear bearing sleeve 522, a support rod 523, a pressing seat 524, and an insertion hole 525. Two support rods 523 are mounted on the frame 1. The pressing cylinder 521 is mounted on the top of the support rods 523. The driving end of the pressing cylinder 521 is provided with a pressing seat 524. A linear bearing sleeve 522 is vertically inserted into the pressing seat 524 and slidably sleeved on the support rod 523. An insertion hole 525 is horizontally opened in the pressing seat 524 for slidingly inserting the connecting rod 513. By controlling the pressing action of the pressing cylinder 521, the pressing seat 524 is driven to move downward under the guidance of the linear bearing sleeve 522, thereby driving the connecting rod 513 and its dotting pin 53 in the insertion hole 525 to press down and dot.

[0046] The unloading mechanism 6 includes an unloading cylinder 61 and an unloading claw 62. The unloading claw 62 is located at the drive end of the unloading cylinder 61 and is arranged in a downward-sloping, mountain-shaped structure. By controlling the unloading cylinder 61 to lift, the unloading claw lifts the marked copper pipe upward and removes it from the V-shaped work station groove 41. When the height is higher than the top of the V-shaped work station groove 41, the unloading claw 62, being inclined downward, slides down to the guide plate 42 under the action of gravity and falls into the receiving frame 7.

[0047] The dotting station seat 4 also includes a V-shaped station groove 41 and a guide plate 42. The guide plate 42 is inclined downward on the dotting station seat 4, and the groove wall of the V-shaped station groove 41 also includes several clearance grooves 43 for accommodating and placing the unloading claw 62.

[0048] The bottom end of the dotting needle 53 also includes an integrally formed dotting protrusion 531. This dotting protrusion 531 is used to press down and dot the inner wall of the copper pipe at a distance of 20mm from the end, thereby forming a protrusion on the outside of the copper pipe. The dotting device operates smoothly, with consistent dotting depth and distance.

[0049] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
