[0003] Traditional die separators generally include a two-claw or three-claw die puller, that is, a structure with an intermediate ejector rod and two or three claw bodies arranged around the intermediate ejector rod. The outer periphery of the workpiece to be disassembled is grasped by the claw bodies, and the central jacking is performed by the threaded rotation of the intermediate ejector rod to realize the separation from the workpiece.
[0004] Generally, the claw body has a radial adjustment displacement, which is realized by means of pivot deflection, etc. Its stroke is relatively limited. During the force application process, it is also easy to cause damage to the pivot structure part, which is not conducive to repeated use. In addition, the intermediate ejector rod generally has an acute or obtuse abutting part, which is a vulnerable part. The traditional ejector rod replacement adopts the method of replacing the whole rod, and its installation and disassembly are difficult. Therefore, maintenance, repair and model change are more difficult. Content of the Utility Model

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0025] The following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only for explaining the relevant utility model and not for limiting the utility model. Additionally, it should be noted that for ease of description, only the parts related to the relevant utility model are shown in the accompanying drawings. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.
[0026] The present utility model provides a disassembly draw die separator, as Figures 1 to 5 shown, which includes a cantilever carrier 1. The cantilever carrier 1 includes a screw pile 2 with a central screw hole 20 and two oppositely extending extension arm bodies 3 provided on the screw pile 2. A push-pull screw 4 is arranged in the central screw hole of the screw pile 2, and a drawing claw 5 with linearly adjustable displacement is provided on any one of the extension arm bodies 3.
[0027] One end of the push-pull screw 4 is provided with a screwing end 41, and the other end is provided with a bearing seat body 42 with rotational displacement. A central positioning thimble 6 is detachably arranged on the bearing seat body 42.
[0028] Specific implementation process and principle description:
[0029] First, adapt and replace the central positioning thimble 6 according to the requirements of the disassembled part.
[0030] After the central positioning thimble 6 is adapted and replaced, first press the central positioning thimble 6 in place. At this time, through the displacement of the drawing claw 5 on the extension arm body 3, its gripping head end is inserted into a suitable position of the workpiece to be disassembled.
[0031] At this time, rotate the screwing end 41. The push-pull screw 4 generates relative rotational displacement in the central screw hole 20, and the central positioning rod 6 and the drawing claw 5 generate relative displacement, thereby realizing the separation of the disassembled workpiece.
[0032] The screwing end 41 can be an external hexagonal bolt head, or it can adopt the design of a bolt groove or an internal hexagonal channel.
[0033] In a specific embodiment, the pulling claw 5 includes a pulling rod 51 and a claw body 52 provided at the free end of the pulling plate rod. Two adjusting hole grooves 50 are provided at intervals on the pulling rod, and the extending arm body is slidably engaged with the adjusting hole grooves.
[0034] That is, the adjusting hole grooves 50 are carried by the pulling rod 51 to meet the disassembly and separation stroke requirements with different stroke differences, and the sliding adjustment is realized by the adjusting hole grooves 50.
[0035] In a specific embodiment, the pulling rod forms an acute angle with the push-pull screw rod.
[0036] That is, as shown in Figures 1 to 3 , the pulling rod presents a certain inclination, so that a certain spatial avoidance of the insertion position can be realized, and at the same time, the relative displacement reliability requirements can be met.
[0037] In a specific embodiment, a mating convex post 421 is provided at the free end of the bearing seat body 42. A ring recess 422 is provided on the mating convex post 421. A mating ring wall 61 for sleeving on the mating convex post is provided on the central positioning thimble 6. A plurality of locking bolt channels 62 are circumferentially and uniformly arranged on the mating ring wall.
[0038] Such a design meets the detachable mating requirements between the central positioning thimble 6 and the bearing seat body 42. Of course, other detachable mating methods can also be adopted, such as combinations of screwing and bolting, combinations of buckles and bolting, locking with embedded buckle parts, axial insertion and radial through connection locking, etc. Any structure that only needs to meet the detachable mating is within the protection scope of this case.
[0039] In a specific embodiment, a detachable limit block 7 is provided at the free end of any extending wall body 3. A limit strip groove 70 for carrying the limit block is provided at the free end of the extending wall body, and a locking through hole is provided in the limit strip groove.
[0040] That is, the pulling claw 5 can be limited by the limit block 7 to prevent it from slipping off. At the same time, operations such as replacing the position of the pulling claw 5 can be realized by removing the limit block 7.
[0041] Through the above description, it can be found that a die pulling separator of the present utility model meets the self-rotation and retype requirements of the central positioning thimble, and is convenient for retyping and maintenance. The insertion and mating separation operations of the pulling claw are convenient and smooth. At the same time, the hole position can be adjusted to adapt to the stroke according to the requirements, the application range is expanded, and the separator has strong versatility. The inclined pulling claw can realize avoidance and meet the operation requirements of no interference when inserted in place. At the same time, its relative push-pull force is reliable and stable.
[0042] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, methods, articles, or apparatus / devices.
[0043] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
