The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.
A simple tooling for pressing flat squares, as shown in fig. 1 to 8, comprising:
the lower die holder 1 is provided with a first arc-shaped groove 2 along the horizontal direction, and the middle part of the lower die holder is vertically provided with a first through groove 3;
the lower pressing block 4 is arranged in the first through groove in a vertically sliding mode;
the upper die holder 5 is matched with the lower die holder, a second arc-shaped groove 6 is formed in the upper die holder along the horizontal direction, and a second through groove 7 is vertically formed in the middle of the upper die holder;
the upper pressing block 8 is arranged in the second through groove in a vertically sliding mode;
a positioning structure is arranged between the upper die holder and the lower die holder and used for ensuring that the second arc-shaped groove corresponds to the first arc-shaped groove and the second through groove corresponds to the first through groove;
after the upper die base and the lower die base are assembled, a workpiece accommodating cavity 13 is formed between the arc-shaped grooves of the upper die base and the lower die base.
The positioning structure comprises raised platforms 9 symmetrically arranged on the lower die base, and concave platforms 10 are arranged on the upper die base corresponding to the raised platforms of the lower die base; the height of the convex table is consistent with the depth of the concave table, and the length directions of the convex table and the concave table are consistent with the axial direction of the accommodating cavity.
In order to improve the matching precision of the upper die holder and the lower die holder and facilitate the assembling operation, in an alternative embodiment, as shown in fig. 6 and 7, the protruding table is provided with a guide post 11, the recessed table is provided with a blind hole 14 matched with the guide post, the depth of the blind hole is generally larger than the length of the guide post, and the situation that the upper die holder and the lower die holder are not installed in place is avoided. As shown in fig. 8, a guiding conical surface (i.e. a chamfer) is arranged at the opening of the blind hole on the upper die holder. The guide post is provided with a tapered guide portion 12 at the top thereof. In the process of assembling and buckling the upper die base and the lower die base, the guide conical surface and the guide part have good guide effect, the guide column can be inserted into the blind hole quickly, the positioning matching precision is high, the combination speed is high, and the working efficiency is high.
The height of the accommodating cavity is slightly smaller than the outer diameter of the pipe 16 to be processed, and the height of the accommodating cavity is actually the minimum inner diameter of a cavity formed by the arc-shaped grooves of the upper die holder and the lower die holder.
When the upper die base and the lower die base are machined and manufactured, in order to reduce the machining matching surface 15 and reduce machining difficulty and cost, the radian of the arc-shaped groove can be increased, and the minimum clearance of the accommodating cavity is slightly smaller than a pipe fitting to be machined as long as the assembly of the upper die base and the lower die base is ensured. Typically, the distance at the minimum clearance of the receiving cavity is 0.1-0.5mm smaller than the diameter of the workpiece.
The upper surface of the upper die holder and the lower surface of the lower die holder are both horizontally arranged planes. The inner side surface and the outer side surface of the upper pressing block and the lower pressing block are both horizontally arranged planes. The deformation of the workpiece during pressing is controllable, and the precision is easier to guarantee.
In an alternative embodiment, the groove depths of the first arc-shaped groove and the second arc-shaped groove are gradually increased towards the outer side at positions close to the corresponding through grooves (the groove depths are smaller as the groove depths are closer to the first through groove and the second through groove; the height of the accommodating groove is closer to the flat width to be formed as the groove depths are closer to the first through groove and the second through groove), that is, the inner diameter of the part of the formed accommodating groove close to the through grooves (the upper/lower pressing blocks) is smaller, and the parts of the accommodating groove opening towards the two sides are gradually increased.
By adopting the structural design, the upper die base and the lower die base are utilized to pre-press the pipe fitting before the flattening action, so that the pipe fitting forms a certain transition area between the non-flattened area and the flattened area, the transition area is in a gradual design mode, burrs generated on the workpiece in the flattening process are avoided to the maximum extent, the quality of finished products is high, and the yield of the workpiece is greatly improved.
The following provides a method for flattening by using the tool,
a lower die base is horizontally placed on the workbench, at the moment, a lower pressing block is not arranged in the lower die base, a pipe fitting to be processed is placed in a first arc-shaped groove of the lower die base, and then the upper die base is buckled;
placing an upper pressing block in a second through groove of the upper die holder, and pressing the upper pressing block to a preset height position by using a press machine, wherein the position is determined by the stroke of the press machine and is easy to control;
the press machine is reset, and the tool is integrally turned over under the condition that the upper pressing block is not disassembled, so that the lower die base is arranged on the upper die base, the upper die base is arranged on the lower die base, and the lower die base is horizontally arranged on the workbench;
and (3) placing a lower pressing block in the first through groove of the lower die holder, and pressing the lower pressing block to a preset height position by using a press machine, wherein the position is determined by the stroke of the press machine. Because the flat square workpieces are mostly aluminum or copper tubes or aluminum tubes, the ductility of the workpieces is good, and the flattening method can realize the equidistant flattening of two sides and the flattening of an eccentric structure, is very convenient to control, has reliable structure and high forming precision, and can adapt to the pressing operation of special structures (such as eccentric flat pressing).
The invention has simple structure, ingenious design and very easy operation, can efficiently flatten the pipe fitting by the combined structural design of the upper die seat, the lower die seat, the upper pressing block and the lower pressing block, is not easy to generate dust, has good product quality and can greatly improve the qualification rate of finished products.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
