Description
Technical Field
The utility model relates to the field of heating pipe die forming, in particular to a multi-channel bending integrated cold stamping forming die for a heating straight pipe.
Background
The heating tube industry current situation can only be single straight tube bend position bending pressure shaping, and is efficient, easily crushes, and not only the yield is high, and the shape is different after the bending pressure shaping, needs increase the correction process. With the development of the years, the bending position of the heating tube is smaller and smaller, and the requirement on appearance wrinkles is higher and higher, so that the reduction of the wrinkles of the bent tube is also extremely important in the bending process.
Disclosure of Invention
In order to solve the problems, the utility model provides a multi-bending integrated cold stamping forming die for a heating straight pipe.
The utility model provides an integrative cold stamping forming mould in straight tube multichannel knee that generates heat, includes upper die fixing plate, lower mould fixed plate, buffer spring, buffer beam, its characterized in that: the device also comprises an upper die, a lower die and a limiting block;
the upper die and the lower die are provided with two cavities with different depths, so that the same die can be punched and formed twice;
the limiting block is matched with the lower die fixing plate, accurate positioning is carried out according to the length of the heating tube, and the limiting block is fixed through a screw.
The limiting block is arranged on the lower die fixing plate, can be adjusted left and right, limits the left and right positions of the heating tube, and is high in flexibility and low in manufacturing cost.
Heating tube passages which are matched with each other are arranged on the lower die cavity and the upper die cavity, and the inner and outer contours of the heating tube passages are the same as those of the required heating tubes.
The die cavity is divided into two dies and two cavities in one die.
The heating straight pipe is punched twice, so that folds at the bent part are reduced, and the heating straight pipe is finally formed.
Be provided with on the lower mould fixed plate and be used for preventing to arouse the lower mould removal when compound die with cold stamping press base complex lower mould set screw counter sink, risks such as reduction wear, error.
The upper die fixing plate is provided with an upper die fixing screw hole used for being matched with the cold punching machine, and pressure is provided for die assembly.
The utility model has the beneficial effects that: the heat pipe passage cavity molds with different heights are designed on the same mold, and are punched and formed for multiple times, so that the heating pipe is prevented from generating wrinkles and depressions due to overhigh height during punching; the limiting blocks on the lower die are made into movable mechanisms which are positioned at two sides of the lower die, and the positions of the limiting blocks are adjusted and fixed according to the length of the heating tube.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic perspective view of the present invention;
FIG. 2 is a schematic front view of the present invention;
FIG. 3 is a schematic perspective view of a lower mold of the present invention;
fig. 4 is a schematic perspective view of an upper mold of the present invention.
Detailed Description
The present invention will be further described below in order to make the technical means, the original characteristics, the achieved objects and the effects of the present invention easy to understand, and the embodiments described herein are only used for explaining the present invention and are not used for limiting the present invention.
As shown in fig. 1 to 3, an integrative cold stamping forming mould of straight tube multichannel that generates heat curved position, including upper die fixing plate 1, lower die fixing plate 4, buffer spring 11, buffer beam 10, still include: the upper die 2, the lower die 3 and the limiting block 5;
the upper die 2 and the lower die 3 are provided with two cavities with different depths, so that the same die can be punched and formed twice;
An upper die fixing screw hole 6 used for being matched with the cold punching machine is formed in the upper die fixing plate 1, and the upper die fixing plate 1 is hinged and matched with the cold punching machine.
The lower die fixing plate 4 is provided with a lower die fixing screw countersunk hole 14 matched with the cold punching machine base and is in hinged fit with the cold punching machine base.
The cushion rod 10 and the cushion spring 11 are used for cushioning impact force generated during mold clamping and providing a positioning function.
Install this mould on cold punching machine earlier fixedly, under the not die closing state, place heating tube 8 on first heating tube passageway 16 spacing, prepare the compound die work afterwards, drive cold punching machine external force makes upper fixing plate 1 descend, upper fixing plate 1 is through articulating the cooperation with last mould 2, make and go up the mould, 2 draw close to lower mould 3 under the external force, simultaneously under the cold punching machine pressure, heating tube 8 draws close and forms upper and lower mould core passageway 16 shapes to lower mould 3, place the heating tube on second heating tube 17 passageway spacing again, the compound die, final shaping.
The heating straight pipe 8 is punched twice, so that the folds at the bent part are reduced, and finally the heating straight pipe is formed.
The mould pin hole of going up in the array set up respectively in four edges of last mould, carry out the chamfer to the pin hole, the cooperation of being convenient for, and cooperate with the pin 9 of lower mould, provide the locate action.
The buffer rod 10 is in hinged fit with the lower die fixing plate 4 through a screw 15.
The use method of the utility model comprises the following steps: install this mould on cold punching machine earlier fixedly, under the not die closing state, place heating tube 8 on first heating tube passageway 16 spacing, prepare the compound die work afterwards, drive cold punching machine external force makes upper fixing plate 1 descend, upper fixing plate 1 is through articulating the cooperation with last mould 2, make and go up the mould, 2 draw close to lower mould 3 under the external force, simultaneously under the cold punching machine pressure, heating tube 8 draws close and forms upper and lower mould core passageway 16 shapes to lower mould 3, place the heating tube on second heating tube passageway 17 spacing again, the compound die, final shaping.
The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
