DETAILED DESCRIPTION
[0024] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with specific embodiments.
[0025] As Figure 2 shown, the utility model provides a kind of full-automatic capillary copper pipe limiting ring forming device, including feeding mechanism and limiting ring forming mechanism;
[0026] The limiting ring forming mechanism includes fixed clamping block group 1 and movable clamping block group 2 arranged forward and backward along the axial direction of capillary copper pipe;The movable clamping block group 2 can reciprocate along the axial direction of capillary copper pipe;When movable clamping block group 2 and fixed clamping block group 1 clamp capillary copper pipe, movable clamping block group 2 moves towards fixed clamping block group 1, so that the limiting ring is extruded on capillary copper pipe;Further comprising push plate 3 for driving movable clamping block group 2 to move along the axial direction of capillary copper pipe;Reset spring 4 is arranged between movable clamping block group 2 and fixed clamping block group 1;
[0027] The limiting ring forming mechanism further includes feeding clamp 5, and the feeding clamp 5 can clamp the capillary copper pipe and drive the capillary copper pipe to move along the axial direction thereof.The feeding clamp 5 can be composed of two left and right clamps, and in the embodiment, the two clamps clamp the capillary copper pipe by rotating inward, and then release the capillary copper pipe by rotating outward.The above-mentioned clamping mode can avoid interference with the capillary copper pipe when clamping.In the embodiment, the feeding clamp 5 is fixed on the mounting plate 6, and the mounting plate 6 is driven by the oil cylinder 7 to move forward and backward along the axial direction of the capillary copper pipe.
[0028] The principle of the utility model lies in that the feeding mechanism separates one capillary copper pipe and sends it to the feeding clamp 5, and then sends it to fixed clamping block group 1 and movable clamping block group 2 to clamp the capillary copper pipe.The formation of the limiting ring relies on that, after the capillary copper pipe is clamped by the two clamping block groups, movable clamping block group 2 approaches fixed clamping block group 1, and through extrusion, the outer surface of the capillary copper pipe forms a raised annular boss to serve as a limiting ring for limiting during connection.
[0029] After the limit ring is formed, the movable clamping block group 2 is reset under the action of the reset spring 4, and the two clamping block groups are loosened from the capillary copper pipe. The capillary copper pipe is clamped by the feeding clamp 5 to exit the range of the clamping block group and is placed into the receiving tray to complete the processing.
[0030] Specifically, the fixed clamping block group 1 and the movable clamping block group 2 in the utility model each include two clamping blocks, i.e., the fixed clamping block I, the fixed clamping block II, the movable clamping block I and the movable clamping block II, which are oppositely arranged along the upper and lower sides of the capillary copper pipe, and the two clamping blocks (i.e., the fixed clamping block I and the fixed clamping block II, and the movable clamping block I and the movable clamping block II) can be moved close to each other to clamp the capillary copper pipe (in this embodiment, the clamping block located at the upper side is moved close to the clamping block located at the lower side). The driving of the clamping block can rely on an oil cylinder, an air cylinder or the like. The clamping principle of the movable clamping block is the same, and thus is not described here.
[0031] In addition, the movable clamping block group 2 can be arranged on a sliding rail and can move along the sliding rail or be guided by a guide rod to avoid deviation, and the movable clamping block group 2 is moved close to the fixed clamping block group 1 by the push plate 3, so as to achieve the purpose of extruding the copper pipe to form a limit ring. In this embodiment, the push plate 3 is driven by an oil cylinder.
[0032] In order to improve the production efficiency and realize automatic feeding, the feeding mechanism in the utility model includes a hopper 8, and a plurality of capillary copper pipes to be processed are arranged in the same direction in the hopper and are stacked in a plurality of layers.
[0033] The bottom surface of the hopper 8 is inclined downward to the discharging direction, so as to facilitate discharging and enable the capillary copper pipes to move to the discharging opening under the action of gravity; further including a pressing plate 9 arranged above the bottom surface of the hopper 8 and parallel to the bottom surface of the hopper 8, and the spacing between the pressing plate 9 and the bottom surface of the hopper 8 is only for one capillary copper pipe to pass through; the pressing plate 8 serves to ensure that the capillary copper pipes are arranged in one row only, so as to avoid separating more than two capillary copper pipes at a time.
[0034] A separating mechanism is arranged at the discharging opening of the hopper, and the separating mechanism includes two forks, i.e., a front fork I11 and a rear fork II12, which are arranged in front of and behind the capillary copper pipe in the discharging direction of the capillary copper pipe, the spacing between the two forks is consistent with the diameter of the capillary copper pipe, and the two forks are alternately lowered and recovered, for separating the outermost capillary copper pipe from other capillary copper pipes in the hopper. The working principle is as follows: initially, the rear fork II12 is lowered to the bottom surface of the hopper 8, and the front fork I11 is retracted, so as to block all the copper pipes in the hopper. When discharging is needed, the fork I11 is lowered, and since the spacing between the fork I11 and the fork II12 is consistent with the diameter of the capillary copper pipe, the outermost capillary copper pipe can be separated from other capillary copper pipes. At the same time, the fork II12 is recovered, so that the outermost capillary copper pipe slides from the hopper 8.
[0035] In order to avoid the clogging of the capillary copper pipe at the front end of the pressing plate 9, the front end of the pressing plate 9 is provided with a pushing block 10, which can reciprocate in the direction parallel to the bottom surface of the hopper 8, and the spacing between the pushing block 10 and the bottom surface of the hopper 8 is consistent with the diameter of the capillary copper pipe. Through the reciprocating movement of the pushing block 10, the capillary copper pipes accumulated at the entrance of the front end of the pressing plate 9 can be dispersed to enter the range of the pressing plate in sequence.
[0036] In order to adapt to capillary copper pipes of different specifications, the spacing between the pressing plate 9 and the pushing block 10 and the bottom surface of the hopper 8 can be adjusted. The adjustment mode can adopt adjusting bolts and the like, which is not limited in the utility model.
[0037] Since the capillary copper pipe to be processed is long, in order to avoid the capillary copper pipe from being inclined, the pressing plate 9, the pushing block 10 and the fork are arranged in two groups along the axial direction of the capillary copper pipe, and the spacing between the two groups can be adjusted to be more appropriate at the two ends of the capillary copper pipe.
[0038] In addition, since the capillary copper pipe discharged from the hopper 8 is not convenient to be clamped by the feeding clamp 5, the feeding mechanism in the embodiment further comprises an intermediate feeding frame 13, which receives the capillary copper pipe discharged from the hopper 8 and sends the capillary copper pipe to the clamping range of the feeding clamp 5. Specifically, the intermediate feeding frame 13 is driven by a pneumatic cylinder 14 to reciprocate between the discharge port of the hopper 8 and the feeding clamp 5. The cross section of the intermediate feeding frame 13 is V-shaped to avoid the capillary copper pipe from sliding. Of course, in order to maintain the balance of the capillary copper pipe during conveying, the intermediate feeding frame 13 can also be arranged in two groups along the axial direction of the capillary copper pipe.
[0039] The above is only the preferred embodiment of the utility model, and it should be pointed out that the above preferred embodiment should not be regarded as the limitation of the utility model, and the protection scope of the utility model should be limited by the scope defined by the claims. For ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the spirit and scope of the utility model, and these improvements and refinements should also be regarded as the protection scope of the utility model.
