Description

Technical Field

[0001] The utility model relates to an integrated machine for shearing and punching heat shrinkable sleeves for capillary copper tubes. 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, corrosion-resistant, light, have 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] A type of capillary copper tube needs to be covered with a heat shrink tubing when in use. The heat shrink tubing is in a roll and needs to be cut and punched before use. The existing processing methods are all manual, which is inefficient and the quality cannot be guaranteed. Utility Model Content

[0008] As an improvement, the punching mechanism further includes a bracket, and the linear drive mechanism is a cylinder fixed on the bracket; the piston rod on the cylinder is connected to the punching needle by means of an L-shaped mounting plate.

[0009] As a further improvement, a mounting hole for mounting a punching needle is provided on the mounting plate, and the punching needle is inserted into the mounting hole and fastened by a locking bolt.

[0010] As another further improvement, the advancing drive device includes a roller group consisting of a plurality of rollers arranged side by side in the same plane and a rubber roller arranged above the roller group; the rubber roller can rotate under the drive of a motor, thereby driving the heat shrinkable sleeve between the rubber roller and the roller group to advance.

[0011] As an improvement, the two ends of the rubber roller are connected to the bearing seat on the mounting plate by bearings; the bearing seat can move up and down along the mounting plate, a spring is provided at the bottom of the bearing seat, and the preload force of the spring is balanced by an adjusting bolt at the top of the bearing seat.

[0012] As an improvement, the knife comprises a vertically arranged blade, and the blade can move up and down to cut the heat shrinkable sleeve.

[0013] As an improvement, a spacing adjustment mechanism for adjusting the spacing between the side-by-side heat shrink tubings is provided between the punching mechanism and the travel drive mechanism.

[0026] 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.

[0027] like Figure 1 As shown, the utility model provides an integrated machine for cutting and punching heat shrinkable tubes, comprising a punching mechanism 1, a travel drive device 3 for driving the heat shrinkable tube to move, and a gate knife 4 for cutting the heat shrinkable tube, which are arranged in sequence from front to back; a spacing adjustment mechanism 2 for adjusting the spacing between parallel heat shrinkable tubes is arranged between the punching mechanism 1 and the travel drive mechanism 3.

[0028] The punching mechanism includes a template 15, such as Figure 2 As shown, the template 15 is radially provided with a plurality of through holes 151 for the heat shrinkable tube to pass through, and the through holes 151 are equidistant from each other; the template 15 is provided with a needle hole 152 located at the top of the through hole to reach the through hole 151; the through hole 151 is used to fix the heat shrinkable tube to avoid radial sliding during punching, so it can be foreseen that the diameter of the through hole 151 should be close to the diameter of the heat shrinkable tube so that the heat shrinkable tube has no space for radial movement.

[0029] A plurality of punching needles 11 are arranged above the template 15 . The punching needles 11 are arranged side by side and face the needle holes 152 on the template 15 one by one. The punching needles 11 are driven by a linear drive mechanism to move up and down to perform punching.

[0030] In this embodiment, the punching mechanism further includes a bracket 14, and the linear drive mechanism is a cylinder 13 fixed on the bracket 14; the piston rod on the cylinder 13 is connected to the punching needle 11 by an L-shaped mounting plate 12. The L-shaped mounting plate 12 can avoid interference between the punching needle 11 and the cylinder 13. The mounting plate 12 is provided with a mounting hole for mounting the punching needle 11, and the punching needle 11 is inserted into the mounting hole and fastened by a locking bolt. After adjusting the height of the punching needle, it can be fastened by the locking bolt for easy adjustment.

[0031] like Figure 3As shown, in the utility model, the spacing adjustment mechanism 2 includes a plurality of gear rods 21 arranged side by side, and screw holes are arranged at both ends of the gear rods 21; it also includes adjustment rods 22 respectively arranged at both ends of the gear rods, the adjustment rods 22 are arranged perpendicular to the gear rods 21, and an axial long hole 24 is opened on the adjustment rods 22; the adjustment bolt 23 passes through the long hole 24 and is connected to the screw hole on the gear rod 21. The gap between the gear rods 21 allows the heat shrink sleeve to pass through, and the gap is adjustable, and after the gap is adjusted, the adjustment bolt 23 can be used to lock it.

[0032] The spacing adjustment mechanism 2 is preferably arranged at a position close to the travel drive mechanism 3. After the position is adjusted, the heat shrink tubing can be prevented from deviating when being driven by the travel drive mechanism 3.

[0033] like Figure 4 As shown, in the utility model, the advancing driving device 3 comprises a roller group 31 composed of a plurality of rollers arranged side by side in the same plane and a rubber roller 32 arranged above the roller group 31; the rubber roller 32 is also arranged in parallel with the rollers in the roller group 31. The rubber roller 32 can rotate under the drive of the motor, thereby driving the heat shrinkable tube between the rubber roller 32 and the roller group 31 to advance. The rubber roller 32 drives the heat shrinkable tube to move forward by the friction between the rubber roller 32 and the heat shrinkable tube, and the roller group 31 assists to reduce the friction at the bottom thereof.

[0034] In addition, the two ends of the rubber roller 32 are connected to the bearing seat 35 on the mounting plate 33 by bearings; the bearing seat 35 can move up and down along the mounting plate, and a spring 36 is provided at the bottom of the bearing seat 35. The top of the bearing seat 35 uses an adjusting bolt 34 to balance the pre-tightening force of the spring 36. The height of the bearing seat 35 can be adjusted by adjusting the bolt 34, thereby adjusting the distance between the rubber roller 32 and the roller group 31 to adapt to heat shrink sleeves of different specifications.

[0035] The knife 4 in the utility model comprises a vertically arranged blade 41, and the blade 41 can move up and down to cut the heat shrinkable sleeve. The blade 41 can be arranged on a bracket and driven by a linear drive mechanism such as a cylinder.

[0036] 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.
