Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.
Example 1:
as shown in fig. 1-2, a special processing die for a three-way catalytic square pipe fitting is used for manufacturing a square pipe. Specifically, the producer sets up this processing mould in the processing pipe earlier, then struts the processing pipe through the deformation of processing mould, props the processing pipe squarely and can accomplish the processing of processing pipe.
Specifically, as shown in fig. 1, the processing die special for the three-way catalytic square tube fitting comprises a left die 1, a right die 2 and a die supporting core 3 with a square vertical cross-sectional shape. One side of the left die 1 is provided with a left through groove 11, one side of the right die 2 is provided with a right through groove 21, and the die core 3 with the square vertical cross-sectional shape is arranged between the left die 1 and the right die 2. Wherein, left side mould 1 sets up with right mould 2 is relative, and the logical groove 11 in a left side is connected with the logical groove 21 in the right side and is formed and prop nib 4, prop the mold core 3 and wear to establish prop the nib 4 in and can remove along the axis direction who props nib 4.
As shown in fig. 2, the diameter of the mold supporting hole 4 gradually decreases from the outer end to the inner end, the width of the mold supporting core 3 gradually decreases from the outer end to the inner end, and the shape of the mold supporting core 3 is matched with the shape of the mold supporting hole 4. Thereby prop the both sides of mold core 3 and can support respectively and lean on the inner wall that leads to groove 21 in a left side and right side, along with propping deepening of mold core 3 and prop nib 4, prop the width at the position of propping nib 4 of mold core 3 and increase to prop open left mould 1 and right mould 2 gradually, make left mould 1 and right mould 2 keep away from each other, and then prop the processing pipe in the outside into squarely, accomplish the shaping of square pipe.
The conventional core brace 3 is generally in the shape of a truncated cone, i.e., a long bar having a circular cross section. When the square pipes of different specifications need to be processed, the diameter of the mold supporting core 3 can only be changed, but the size of the whole mold supporting core 3 can be changed after the diameter is changed, the distance between the supported left mold 1 and the supported right mold 2 can be changed under the condition that the mold supporting core 3 moves by the same stroke, so that a producer needs to recalculate the stroke related to debugging, the processing pipe can be accurately processed to the set size, the adaptation is relatively inflexible when different production requirements are met, and the required operation of the producer is relatively troublesome.
In the embodiment, the left and right molds are opened by the mold opening core 3 with a square vertical cross section, the whole mold is in a frustum pyramid shape, and the mold opening 4 is in a frustum pyramid shape matched with the frustum pyramid shape. When a producer needs to switch to produce a square tube with another specification, the producer can select the mold supporting core 3 with the changed width or height or the changed width and height according to the corresponding production requirement, namely, the distance for supporting the left mold and the right mold can be changed under the condition that the mold supporting core moves the same stroke by only changing one size of the mold supporting core 3. The selection of the producer is wider and more flexible, and the producer can adapt to more production requirements. And when only the height or the width is changed, the mold supporting core 3 only changes a part of the size, but not changes the diameter like a circular mold supporting cavity, namely changes the size of the whole, so that the steps of recalculating and debugging the stroke required by a producer can be easier and more convenient.
Further, as shown in fig. 1, four end corners of the mold supporting core 3 are in contact with the inner wall of the mold supporting hole 4, and all the four end corners are rounded. Thereby reduce and prop the deformation volume that the die cavity caused to left mould 1 and 2 application of force of right mould, reduce the deformation of left mould 1 and right mould 2 promptly, reduce the influence to left mould 1 and right mould 2 normal use, prolong the life of left mould 1 and right mould 2.
As shown in fig. 1, in this embodiment, the cross-sectional shape of the mold supporting core 3 may be preferably square, and the cross-sectional shapes of the left through groove 11 and the right through groove 21 are rectangles matched with each other. Therefore, when the mold core 3 is used for opening the left mold and the right mold, the stress of the left mold 1 and the right mold 2 can be more balanced.
Example 2:
as shown in fig. 3, this embodiment is substantially the same as embodiment 1, except that a left mounting groove 12 is formed on one side of the left mold 1 close to the right mold 2, and a right mounting groove 22 is formed on one side of the right mold 2 close to the left mold 1; an elastic part 5 is arranged between the left die 1 and the right die 2, one end of the elastic part 5 is arranged in the left mounting groove 12, and the other end of the elastic part is arranged in the right mounting groove 22. Thereby mould is strutted and the processing pipe is processed the completion about making through the effect of elastic component 5, props mould core 3 and withdraws from the back, and mould can accomplish automatic re-setting through elastic component 5 about to be ready for the producer to use next time, simple structure, the user uses more conveniently.
As shown in fig. 3, the left mounting groove 12 is disposed on both sides of the left mold 1, the right mounting groove 22 is disposed on both sides of the right mold 2, and the elastic member 5 is disposed in the left mounting groove 12 and the right mounting groove 22. Namely, an upper elastic piece 5 and a lower elastic piece 5 are arranged between the left die and the right die so as to ensure the balance between the left die 1 and the right die 2 when the dies are reset.
As shown in fig. 3, a guide groove or a guide block is arranged on one side of the left mold 1 close to the right mold 2, a guide block or a guide groove matched with the left mold 1 is arranged on one side of the right mold 2 close to the left mold 1, and the left mold 1 and the right mold 2 are guided to move by the sliding of the guide block in the guide groove. Therefore, the left die and the right die can move more stably, the moving direction between the left die and the right die can tend to a straight line, the machining quality of a finished square tube is guaranteed, and the yield of the square tube is improved.
As shown in fig. 3, the upper side of the left mold 1 is provided with an upper guide groove 13, and the upper side of the right mold 2 is provided with a corresponding upper guide block 23; a lower guide block 14 is arranged on the lower side of the left die 1, and a corresponding lower guide block 14 is arranged on the lower side of the right die 2; the upper guide block 23 is arranged in the upper guide groove 13 and the lower guide block 14 is arranged in the lower guide groove 24, so that the upper and lower sides of the left mold 1 and the right mold 2 are guided. Therefore, the movement of the upper side and the lower side of the left die and the right die can be more balanced and stable through the design of the guide blocks and the guide grooves on the upper side and the lower side.
Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
