Description

Technical Field

[0001] The utility model specifically relates to an adjustable structure of a pipe bending clamping die. Background Art

[0002] In the metal processing industry, the pipe bending forming technology is widely used in various fields. Pipe bending forming refers to the process of bending a straight pipe into a required shape through a specific die. This process requires a high degree of precision and repeatability to ensure the quality and performance of the finished pipe fittings. Traditional pipe bending clamping dies usually consist of a fixed pipe bending die and a movable clamping die seat. The position of the clamping die seat is adjusted to clamp the pipe, and then it is bent to a predetermined curvature radius by mechanical force. Specifically, reference can be made to a pipe bending mechanism previously developed by the applicant of the present utility model. The detailed structure refers to the patent solution of a pipe bending mechanism of a pipe bender with the patent number CN201310634656.4 and the name of a pipe bending mechanism of a pipe bender. For the above single-function pipe bending structure, generally, the fixed pipe bending die and the pipe bending clamping die are installed and fixed on the equipment. Once the installation structure of the two loosens or wears, it will affect the precision of the pipe bending process. At this time, the fixed pipe bending die and the pipe bending clamping die cannot be adjusted and can only be replaced, resulting in low production efficiency. If not maintained for a long time, it will lead to poor manufacturing precision of the product and low product quality.

[0003] The present utility model is precisely produced based on the above deficiencies. Summary of the Utility Model

[0021] The present utility model will be further described below with reference to the accompanying drawings:

[0022] The directions described in the utility model specification, such as "upper", "lower", "left", "right", "front", "rear", etc., are all based on the directions of the drawings and are for the purpose of facilitating the description of the relationships between various components, rather than indicating the only or absolute positional relationships between various components. It is only one implementation mode for realizing the utility model and does not limit its implementation mode.

[0023] As Figures 1 to 4 shown, in this embodiment, an adjustable structure of an elbow pipe clamping die is provided, which includes a base 1. A bending die 2 is provided on the base 1. A clamping die seat 3 that can slide on the base 1 and approach or move away from the bending die 2 is provided. A plurality of curved first mating grooves 200 are provided on the bending die 2. A plurality of clamping blocks 31 corresponding to the first mating grooves 200 one by one are provided on the clamping die seat 3. A second mating groove 300 is provided on the clamping block 31, which can form an elbow pipe channel together with the corresponding first mating groove 200 when the clamping die seat 3 approaches the bending die 2. In this embodiment, three arc-shaped first mating grooves 200 are provided on the bending die 2, and three clamping blocks 31 are correspondingly provided on the clamping die seat 3. The second mating grooves 300 on each clamping block 31 and the first mating grooves 200 form a precise circular channel after being closed. Of course, 1-2 first mating grooves 200 can also be provided on the bending die 2, or more than 3 first mating grooves 200 can be provided, and only the corresponding number of clamping blocks 31 need to be provided on the clamping die seat 3.

[0024] An adjusting mechanism 4 is further provided on the clamping die base 3 for adjusting the movement of each clamping block 31 in a direction approaching or moving away from the bent pipe die 2. A preferred embodiment of the adjusting mechanism 4 is as follows:

[0025] As Figures 1 to 4 shown, the adjusting mechanism 4 includes a number of adjusting blocks 41 slidably connected to the clamping die base 3 and arranged in one-to-one correspondence with the clamping blocks 31. The clamping block 31 is provided with an inclined first mating surface 311, and the adjusting block 41 is provided with a second mating surface 411 that abuts and cooperates with the first mating surface 311 of the corresponding clamping block 31. The adjusting mechanism 4 further includes a locking member 42 disposed between the clamping block 31 and the clamping die base 3 for pushing the clamping block 31 against the adjusting block 41 so that the first mating surface 311 and the second mating surface 411 are tightly fitted, and the adjusting mechanism 4 further includes a driving rod 43 capable of pushing the adjusting block 41 to slide; preferably, as Figure 3 shown, a sliding groove 100 is provided on the base 1 along the longitudinal direction, and the adjusting block 41 is arranged in the sliding groove 100.

[0026] As Figure 3 shown, the locking member 42 is a first screw. The clamping die base 3 is provided with a mating hole 32 for the first screw to pass through. The diameter of the mating hole 32 is smaller than the radial dimension of the head of the first screw, so that the head of the first screw is stuck outside the mating hole 32. The tail of the first screw is threadedly connected to the clamping block 31, and the adjusting block 41 is disposed between the corresponding clamping block 31 and the mating hole 32, so that the clamping block 31 is pressed against the adjusting block 41 when the first screw is tightened.

[0027] As Figure 3 shown, the driving rod 43 is a second screw. The clamping die base 3 is provided with a corresponding through hole. The diameter of the through hole is smaller than the head of the second screw, so that the second screw can rotate relative to the clamping die base 3. The second screw passes through the clamping die base 3 and is threadedly connected to the corresponding adjusting block 41.

[0028] In this embodiment, three clamping blocks 31 are provided on the clamping die base 3, and correspondingly three adjusting blocks 41 are provided. The three adjusting blocks 41 are respectively a first adjusting block 41a, a second adjusting block 41b, and a third adjusting block 41c. The three adjusting blocks 41 are stacked. Correspondingly, three groups of driving rods 43 are provided. The three groups of driving rods 43 are respectively a first driving rod 43a, a second driving rod 43b, and a third driving rod 43c. The first driving rod 43a is threadedly connected to the first adjusting block 41a. A first through hole 410a for the second driving rod 43b and the third driving rod 43c to pass through is provided on the first adjusting block 41a. After passing through the first adjusting block 41a, the second driving rod 43b is threadedly connected to the second adjusting block 41b. A second through hole 410b for the third driving rod 43c is provided on the second adjusting block 41b. After passing through the second adjusting block 41b, the third driving rod 43c is threadedly connected to the third adjusting block 41c. Similarly, one or two clamping blocks 31 or more than three clamping blocks 31 can also be provided, and the same number of adjusting blocks 41 can be correspondingly provided.

[0029] As Figure 3 shown, the three adjusting blocks 41 are stacked longitudinally, and the clamping blocks 31 and the corresponding adjusting blocks 41 are arranged transversely.

[0030] As Figure 3 and Figure 4 shown, a first through hole 412 for the locking member 42 to pass through is provided on the adjusting block 41, that is, the first screw passes through the adjusting block 41 through the first through hole 412. Preferably, the first through hole 412 is a long strip-shaped hole arranged longitudinally, so that the adjusting block 41 will not be interfered by the first screw when moving up and down. Of course, the first through hole 412 may not be set as a long strip-shaped hole, as long as there is a certain movement space for the first screw in the first through hole 412.

[0031] During work, the clamping die base 3 approaches the bending die 2. After the second fitting groove 300 and the first fitting groove 200 are closed, a precise circular channel is formed. During work, problems such as firm connection parts and material wear may occur on the clamping blocks 31 on the clamping die base 3, which will ultimately lead to inaccuracy of the channel formed by the second fitting groove 300 and the first fitting groove 200. In this way, by respectively rotating one or more of the first driving rod 43a, the second driving rod 43b, or the third driving rod 43c, the positions of the first adjusting block 41a, the second adjusting block 41b, or the third adjusting block 41c in the longitudinal direction can be adjusted. Then, by rotating the corresponding locking member 42, the positions of the respective clamping blocks 31 in the transverse direction can be adjusted, so as to reduce the error caused by long-term work of the clamping blocks 31. The whole structure is compact, the operation is convenient, the service life and working accuracy of the clamping die are improved, and the manufacturing accuracy of the product is improved.

[0032] The above are only the embodiments of the present utility model, and common general knowledge such as specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope required by this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
