Description

Technical Field

[0001] The utility model relates to a device for straightening and cutting a capillary copper tube. Background Art

[0002] Copper and copper alloy capillaries, also known as copper capillaries, are a type of pressed and drawn seamless tubes that are strong and corrosion-resistant, lightweight, with good thermal conductivity and high low-temperature strength. They are often used to manufacture heat exchange equipment (such as condensers, etc.). They are also used to assemble low-temperature pipelines in oxygen production equipment. Copper capillaries with small diameters are often used to transport pressurized liquids (such as cooling systems, lubrication systems, oil pressure systems, etc.) and as pressure measuring tubes for instruments.

[0003] Some capillary copper tubes used as joints need to be made into piers and flares. Before making the piers and flares, the capillary copper tubes need to be straightened from the coil state and cut into suitable lengths. The existing straightening and cutting are all done by manual tooling, which is inefficient. Utility Model Content

[0004] In view of this, the utility model provides a capillary copper tube straightening and cutting device to realize the automation of capillary copper tube straightening and cutting.

[0005] In order to solve the above technical problems, the technical solution of the utility model is to adopt a capillary copper tube straightening and cutting device, including a straightening mechanism and a cutting mechanism arranged in sequence from front to back; a travel driving mechanism for driving the capillary copper tube to travel is arranged between the straightening mechanism and the cutting mechanism;

[0008] As a further improvement, the slide rail is arranged horizontally and perpendicular to the travel direction of the capillary copper tube; and also includes a linear drive mechanism for driving the electric saw to move along the slide rail.

[0009] As another further improvement, the receiving tray can be flipped along a rotating shaft, and the rotating shaft is parallel to the travel direction of the capillary copper tube; it also includes a flipping cylinder for driving the receiving tray to flip; a finished product loading box is arranged under the feeding tray.

[0010] As an improvement, one side of the receiving tray is a vertical baffle, and the other side is an inclined baffle; the turning cylinder can drive the receiving tray to turn toward the inclined baffle side.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1 , Figure 2 As shown, the utility model provides a capillary copper tube straightening and cutting device, comprising a straightening mechanism 1 and a cutting mechanism 5 arranged in sequence from front to back; a travel driving mechanism for driving the capillary copper tube to travel is arranged between the straightening mechanism 1 and the cutting mechanism 5;

[0026] The cutting mechanism 5 includes a clamping block 51 for clamping the capillary copper tube and an electric saw 52 for cutting the capillary copper tube; the clamping blocks 51 are arranged in groups of two oppositely disposed blocks, and are arranged in two groups, front and rear; a gap is left between the two groups of clamping blocks 51 for the electric saw 52 to pass through; and a slide rail 53 is also included, and the electric saw 52 is arranged on the slide rail 53 and can move along the slide rail 53. It is foreseeable that the two clamping blocks 51 in the clamping block group can move toward the middle to clamp the capillary copper tube. The clamping blocks 51 can be driven to move by a linear drive mechanism such as an oil cylinder or an air cylinder.

[0027] The principle of the utility model is: the copper tube is driven to move forward by the travel drive mechanism, so that it passes through the straightening mechanism 1 and is straightened by the straightening mechanism; the straightened copper tube passes through the cutting mechanism 5, and is clamped from the front and rear by the front and rear two sets of clamping blocks 51, and the electric saw 52 cuts the copper tube between the front and rear two sets of clamping blocks 51, ensuring that the copper tube does not deviate when cutting. The electric saw can reciprocate linearly on the slide rail, and after completing the cutting work, the electric saw retreats to avoid blocking the copper tube.

[0028] In this embodiment, each group of clamping blocks 51 consists of two blocks arranged in the left and right directions; in order to ensure a stable clamping, a clamping groove is provided on the clamping block, and the cross-section of the clamping groove is semicircular, which is consistent with the external shape of the capillary copper tube. A receiving tray 6 is arranged below the cutting mechanism 5. If the clamping block 51 is arranged in the up and down directions, then after the capillary copper tube is cut off, since the clamping block 51 is supported from below, the capillary copper tube cut off in the front needs to be pushed out by the capillary copper tube at the rear before the material can be discharged. If a capillary copper tube with a small diameter is being processed, it is very easy to tilt and cause damage to the capillary copper tube. In this embodiment, a left and right clamping method is adopted, and the capillary copper tube cut off naturally falls onto the receiving tray 6 after the clamping block 51 is released, thereby ensuring smooth discharge.

[0029] Since the clamping block 51 is arranged in the left-right direction, the slide rail 53 in this embodiment is arranged horizontally and perpendicular to the traveling direction of the capillary copper tube; a linear driving mechanism is also included for driving the electric saw 52 to move along the slide rail. Such an arrangement can save space and gradually reduce the footprint.

[0030] The receiving tray 6 can be turned along the rotating shaft 61, and the rotating shaft 61 is parallel to the traveling direction of the capillary copper tube; it also includes a turning cylinder 62 for driving the receiving tray 6 to turn; a finished product loading box 7 is arranged below the feeding tray 6. One side of the receiving tray 6 is a vertical baffle, and the other side is an inclined baffle. The turning cylinder 62 can drive the receiving tray 6 to turn toward the inclined baffle side, so as to pour the capillary copper tube in the receiving tray 6 into the finished product loading box 7, so as to facilitate the neat arrangement of the cut capillary copper tubes.

[0031] The straightening mechanism 1 in this embodiment includes a straightening box 11; the two ends of the straightening box 11 are movably connected to the column, so that the straightening box 11 can rotate along its own axis; the two ends of the straightening box 11 are provided with through holes for the capillary copper tube to enter and exit; a plurality of straightening modules 12 are arranged along the axial direction of the straightening box 11; the straightening module 12 is provided with a straightening groove 13 coaxial with the axis of the straightening box 11. When the straightening box 11 rotates, the capillary copper tube passes through the straightening box 11 and is straightened by the straightening groove 13 on the straightening module 12.

[0032] In addition, the straightening grooves 13 on adjacent straightening modules 12 are staggered by 90° on the circumference, thereby ensuring the straightening effect.

[0033] In this embodiment, the travel driving mechanism is a pair of driving wheels 2 arranged on the same plane to clamp and rotate the capillary copper tube. There is a certain friction between the pair of driving wheels 2 and the capillary copper tube, and the capillary copper tube is driven by rotation.

[0034] A guide wheel pair 3 is arranged between the travel driving mechanism and the cutting mechanism 5, and a guide tube 4 is arranged between the guide wheel pair 3 and the cutting mechanism 5, both of which are used to guide the capillary copper tube to prevent the capillary copper tube from deviating.

[0035] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
