DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0021] Please refer to 1-3, a horizontal crimping machine for an air spring, comprising: a frame 1, a guide rail 2 and a die head 5 are arranged on the top of the frame 1, a base 6 is slidably arranged on the guide rail 2, a chuck 3 is fixedly installed on the base 6, an air spring is clamped in the chuck 3, a hydraulic device is arranged in the frame 1 to supply pressure to the die head 5, and the guide rail 2 is equipped with a servo motor group.

[0022] Specifically, the utility model crops the air spring as a whole onto the chuck 3, and the servo motor drags the guide rail 2 to move the chuck 3 and the air spring assembly to the right, so that the position on the air spring that needs to be buckled is located in the die head 5, and the buckling is completed through the die head 5, avoiding the need to hold the air spring in the die head 5 for buckling, thereby greatly improving the buckling stability, optimizing the buckling process, improving the buckling quality, and greatly improving the buckling efficiency.

[0023] Furthermore, the chuck 3 includes a fixing ring 31, the bottom end of which is fixedly mounted on the base 6, a slide groove 32 is provided in the fixing ring 31, a plurality of arc blocks 33 are arrayed in the slide groove 32, the arc blocks 33 are slidably arranged in the slide groove 32, the arc blocks 33 are connected to a fixing plate 36 via a connecting rod 37, and the fixing ring 31 and the fixing plate 36 are connected via a spring 35.

[0024] Specifically, refer to Figure 2 One end of the spring 35 is fixedly connected to the fixing ring 31, and the other end of the spring 35 is fixedly connected to the fixing plate 36. The arc block 33 is slidably set in the slide groove 32. The three arc blocks 33 are slid outward so that the gap between the three arc blocks 33 is sufficient to accommodate the air spring to enter, and then the air spring is clamped by the elastic force of the spring 35. Compared with the buckling operation of the handheld air spring, it has higher stability and saves manpower.

[0025] Furthermore, a plurality of electromagnets 34 are disposed in the fixing ring 31 . The electromagnets 34 are sleeved on the outside of the connecting rods 37 . The electromagnets 34 correspond to the arc blocks 33 one by one.

[0026] Specifically, an electromagnet 34 is provided on the outer sleeve of the connecting rod 37, and the electromagnet 34 is fixedly installed in the fixing ring 31, and the arc block 33 is a symmetrical structure. When the electromagnet 34 is energized, the magnetic force generated by the electromagnet 34 acts evenly on the arc block 33, so that the arc block 33 abuts against the wall of the slide groove 32 under the action of the magnetic force of the electromagnet 34, so that the space formed between the three arc blocks 33 becomes larger, which is convenient for inserting the air spring. Then, by cutting off the power, the arc block 33 squeezes the air spring under the action of the elastic force of the spring 35, thereby achieving the purpose of clamping the air spring.

[0027] Furthermore, anti-skid pads 331 are provided on the inner sides of the plurality of arc-shaped blocks 33 that are close to each other.

[0028] Specifically, the anti-skid pad 331 is fixedly connected to the arc block 33. By setting the anti-skid pad 331, when the three arc blocks 33 squeeze the outer wall of the air spring, the anti-skid pad 331 is deformed and then adheres to the surface of the air spring, so that the air spring is clamped more stably.

[0029] In this utility model, reference is made to Figure 3 The air spring generally consists of 6 parts, namely, the upper joint 41, the capsule 42, the lower joint 43, the aluminum tube 44, the upper clamping ring 45, the aluminum tube inner ring 46 and the lower clamping ring 47. Among them, the upper joint 41 and the capsule 42 are buckled by the upper clamping ring 45, the aluminum tube 44 and the capsule 42 are buckled at the aluminum tube inner ring 46, and the lower joint 43 and the capsule 42 are buckled at the lower clamping ring 47; there are 3 places to buckle; for the convenience of buckling, the various parts of the air spring are connected into one body with a core rod 48. Reference Figures 1 to 3 After the air spring and the core rod 48 are connected as one, the whole is clamped onto the chuck 3. The servo motor drags the guide rail 2 to move the chuck 3 and the air spring to the right, so that the buckling position of the lower clamping ring 47 of the air spring is just located in the die head 5. The buckling command is issued, and the die head 5 buckles the lower clamping ring 47 and the lower joint 43 into one. Then the guide rail 2 moves to the left and withdraws from the die head 5. The buckling operation of the inner ring 46 of the aluminum cylinder and the upper clamping ring 45 is the same as above.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
