[0017] The tube shrinking mold 21 is slidably connected to the base 1, and the bottom surface of the cavity plate 9 is fixedly connected to the top surface of the base 1.
[0018] By adopting the above technical solution, the tube shrinking machine typically includes a worktable, a clamp, a tube shrinking mold 21, and a positioning plate. When in use, the tube is first placed on the clamp, ensuring that one end of the tube abuts against the positioning plate. Then, the clamp is activated to press down and clamp the tube. Finally, the tube shrinking mold 21 is used to shrink and form the tube. The base 1 is used to support the cavity plate 9 and the tube shrinking mold 21. The tube shrinking mold 21 can move back and forth on the base 1 to cooperate with one end of the tube body 20 to shrink and form the tube body 20. The bottom surface of the movable support plate 12 is provided with a hinge, and the movable end face of the hinge is fixed to the end face of the cavity plate 9.
[0019] A first limiting plate 3 is fixedly connected to the upper part of the side wall of the fixed support plate 2, and a fixed seat 5 is sleeved on the side wall of the electric cylinder 4. The side of the fixed seat 5 away from the electric cylinder 4 is fixedly connected to the top surface of the first limiting plate 3.
[0020] By adopting the above technical solution, when feeding material into the tube 20, the second electric push rod 16 is activated, and the feeding plate 17 can rise under the action of the output shaft of the second electric push rod 16. Figure 2 As shown, a single tube 20 on the feeding rack 15 is transported. When the feeding plate 17 rises to the position corresponding to the inclined plate 8, the top surface of the feeding plate 17 is inclined, so that the tube 20 on the feeding plate 17 can slide down onto the inclined plate 8, and then move to the fixed support plate 2 and the movable support plate 12 via the inclined plate 8. The first limiting plate 3 and the second limiting plate 13 are set to block the sliding tube 20 and prevent the tube 20 from moving excessively and falling. Then, the electric cylinder 4 is activated, and the pressure plate 6 moves down under the action of the output shaft of the electric cylinder 4 to press and fix the tube 20 to prevent the tube 20 from moving during tube shrinking.
[0021] The top surface of the fixed support plate 2 is concave, the bottom surface of the pressure plate 6 is inverted concave, and the pressure plate 6 corresponds to the fixed support plate 2. The top surface of the movable support plate 12 is fixedly connected to the second limiting plate 13, and the top surface of the movable support plate 12 is concave.
[0022] By adopting the above technical solution, the concave fixed support plate 2 and the movable support plate 12 facilitate the support of the tube body 20, and the inverted concave pressure plate 6 facilitates the pressing and fixing of the tube body 20. The tube shrinking mold 21 is an existing mature component, and its structure consists of an outer sleeve, an inner sleeve, and a mandrel. The outer sleeve is the outer layer of the tube shrinking mold, which is usually used to fix and protect the internal components. The inner sleeve is the core part of the tube shrinking mold, which cooperates with the outer sleeve to form a friction surface. The compression and expansion of the tube are achieved by inserting and withdrawing the mandrel. The mandrel is the key component for inserting and withdrawing to achieve the compression and expansion of the tube. Its insertion and withdrawal action is completed by the friction between the outer sleeve and the inner sleeve. These components work together to enable the tube shrinking mold 21 to perform tube expansion and shrinking operations on the tube in the tube shrinking machine.
[0023] The bottom surface of the inclined plate 8 is fixedly connected with the vertical plate 7, and the bottom surface of the vertical plate 7 is fixedly connected with the top surface of the base 1.
[0024] By adopting the above technical scheme, the inclined plate 8 is installed and fixed through the vertical plate 7, and the inclined surface of the inclined plate 8 faces the fixed support plate 2.
[0025] The top surface of the cushion table 14 is embedded with the second electric push rod 16, the output shaft end of the second electric push rod 16 is fixedly connected with the middle part of the bottom surface of the feeding plate 17, and the top surface of the feeding plate 17 is fixedly connected with the baffle 18 on both sides.
[0026] By adopting the above technical scheme, the second electric push rod 16 is started, and the feeding plate 17 can be lifted under the action of the output shaft of the second electric push rod 16 to transport the pipe body 20, and the bottom surface of the feeding plate 17 is fixedly connected with the guide rod 19 on both sides, the bottom end of the guide rod 19 penetrates the cushion table 14, and the guide rod 19 is slidingly connected with the cushion table 14, and it should be noted that when the guide rod 19 is installed, the outer arc surface of the guide rod 19 is flush with the end surface of the feeding plate 17, so that when the feeding plate 17 is lifted, the guide rod 19 can block the remaining pipe bodies 20 on the feeding frame 15, so as to avoid the remaining pipe bodies 20 falling into the notch of the feeding frame 15 and affecting the working process of automatic continuous feeding.
[0027] The top surfaces of the feeding frame 15 and the feeding plate 17 are inclined, and the inclined surface of the feeding frame 15 is placed with the pipe body 20.
[0028] By adopting the above technical scheme, the inclination angles of the feeding frame 15 and the feeding plate 17 are the same, and the inclined surfaces of the feeding frame 15 and the feeding plate 17 face the inclined plate 8.
[0029] Working principle: when the utility model is used, the pipe bodies 20 are placed on the feeding frame 15 in sequence, when the pipe bodies 20 need to be shrunk, the second electric push rod 16 is started, the feeding plate 17 can be lifted under the action of the output shaft of the second electric push rod 16 to transport the single pipe body 20 on the feeding frame 15, when the feeding plate 17 rises to the position corresponding to the inclined plate 8, the top surface of the feeding plate 17 is inclined, so that the pipe body 20 on the feeding plate 17 can slide onto the inclined plate 8, and then move to the fixed support plate 2 and the movable support plate 12 through the inclined plate 8;
[0030] Then, the electric cylinder 4 is started, the pressing plate 6 is moved downward under the action of the output shaft of the electric cylinder 4 to press and fix the pipe body 20, so as to avoid the movement of the pipe body 20 during the pipe shrinking, and then the pipe material can be shrunk and formed by using the pipe shrinking die 21;
[0031] Then, the pressing plate 6 is lifted, the first electric push rod 11 is started, and the movable support plate 12 can rotate through the hinge under the action of the output shaft of the first electric push rod 11, at this time, the top surface of the movable support plate 12 no longer corresponds to the top surface of the fixed support plate 2, so that the pipe body 20 formed by the shrink pipe can be separated to complete the automatic unloading work.
[0032] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
