Abstract
The utility model relates to a punching molding die, in particular to an opening-shrinkage die used for conducting inner side turning on a pipe body. The die comprises a die handle for installation connection and a die head used for conducting opening shrinkage on a roller body. A cylindrical die cavity is arranged on the die head, and a circular recessed die is arranged at the connection position of the bottom side and the lateral side of the die cavity. The die is simple in structure and low in cost. After the die is installed on an opening-shrinkage mechanical device, roller bodies large in an inward-bending and curving degree can be smoothly machined.
Description
Technical field
The utility model relates to a kind of shaped by fluid pressure mould, specifically a kind of closing-in mould that body is carried out in-flanges.
Background technology
Roller conveyor has a wide range of applications in all kinds of logistics treatment systems such as airport, harbour, coal mining industry, and it can carry the bigger material of single-piece weight, can also bear bigger shock loading simultaneously, has advantages such as conveying capacity is big, speed is fast.In roller conveyor, roller tube is directly carrying material, so the crudy of roller tube plays an important role for the running quality of roller conveyor integral body, and roller tube mainly to be the closing in quality at cylindrical shell both ends can bring influence to cylindrical shell operation.The cylindrical shell that generally uses in the prior art, owing to lack the mould that can make cylindrical shell carry out the inside closing in of big distance smoothly, make the cylindrical shell that uses at present, the arc bending of similar chamfering is just done in the closing at its two ends usually in the cylinder lumen, and the closing in amplitude is less.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of closing-in mould simple in structure, with low cost is provided, and it can be operated the closing in that carry out by a relatively large margin at the roller tube two ends after being installed on roller conveyor.
The technical scheme that provides according to the utility model: a kind of closing-in mould, comprise for the die head of the die shank that connects being installed and being used for roller tube is closed up, it is characterized in that: offer cylindrical mold cavities on the described die head, described die cavity base and side junction are provided with the circular arc die.
As further improvement of the utility model, described circular arc die is connected with the side of die cavity is tangent, and the junction, base of die and die cavity forms boss.
As further improvement of the utility model, described die cavity side has gradient, and die cavity openend diameter is greater than the diameter of die cavity bottom.
As further improvement of the utility model, described die shank is provided with mounting groove.
The utility model compared with prior art, advantage is: (1) is simple in structure, with low cost; (2) be installed on the closing in plant equipment after, can process the bigger roller tube of the crimp amplitude that bends inwards smoothly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2, die head 1, die shank 2, die cavity 3, die 4, boss 5, mounting groove 6 etc.
As shown in Figure 1, 2, the utility model is a kind of closing-in mould, comprise that for the die head 1 of the die shank 2 that connects being installed and being used for roller tube is closed up offer cylindrical mold cavities 3 on the described die head 1, described die cavity 3 bases and side junction are provided with circular arc die 4.
Described circular arc die 4 is connected with the side of die cavity 3 is tangent, and die 4 forms boss 5 with the junction, base of die cavity 3.
Described die cavity 3 sides have gradient, and die cavity 3 openend diameters are greater than the diameter of die cavity 3 bottoms.
Described die shank 2 is provided with mounting groove 6.
The utility model course of work is as follows: at first the utility model is installed on the closing in machine, namely, the correspondence that mounting groove 6 on the die shank 2 is installed in the closing in machine is installed on the station, then roller tube to be processed is fixedly mounted on the closing in machine, regulate the amount of feeding of closing in machine according to actual needs, the closing in machine can be pressed into the roller tube end in the die cavity 3 then, after the roller tube end closely is connected on die cavity 3 bases, the further feeding of closing in machine, the roller tube end will be squeezed in the circular arc die 4, the closing in machine continues feeding, can finish the closing in processing of roller tube.
The utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, physical dimension of the present utility model can be done any type of modification, all in protection domain of the present utility model.
