The bent-pipe pressing forming device has simple structure, less components, low manufacturing cost, and is suitable for popularization and application.

Description

The bend pipe punch forming device
Technical field
The utility model relates to a kind of bend pipe punch forming device.
Background technology
Present brake forming at steel pipe, the back-up sand molding mode is made in the domestic main employing pipe, existing conventional automobile front beam 8 for example shown in Figure 2, and it is to be made by the mode of steel pipe by back-up sand moulding in managing, pipe fitting two of final finished is bent downwardly, and it is trapezoidal that integral body is; The then main abroad interior oiling molding mode of pipe that adopts is made, and the shortcoming of Cun Zaiing is as follows respectively:
1, for traditional back-up sand molding mode of domestic use, the less stable of pipe fitting in the process, and working (machining) efficiency is low, is unfavorable for the production in enormous quantities of product.
2, for external oiling molding mode, the technological requirement height, the equipment cost height, equipment is difficult to from external introduction.
Summary of the invention
The utility model purpose is: provide a kind of simple in structure, and the bend pipe punch forming device that cost is low, this device can be simplified the brake forming mode of pipe fitting greatly, improves working (machining) efficiency.
The technical solution of the utility model is: a kind of bend pipe punch forming device is characterized in that it is made of jointly diel and clamping positioning mechanism; Described diel comprises the last punch and the lower cavity die of form fit, and described clamping positioning mechanism comprises lateral arrangement in ambilateral two moving cylinders of stamping die, and the head of each moving cylinder all is fixed with for supporting into the alignment pin in the pipe fitting one side pipe mouth.
Go up punch described in the utility model and further be fixed on the upper bolster, this upper bolster fixes with the platform of going to bed of existing conventional oil pressure lathe, and lower cavity die then further is fixed on the die shoe, and this die shoe fixes with the platform of leaving the bed of described oil pressure lathe.
The opposite face of going up punch and lower cavity die described in the utility model is a stamping surface, further offer the last cavity of applying pipe fitting upper surface on the stamping surface of wherein said upward punch, then further offer the following cavity of applying pipe fitting lower surface on the stamping surface of described lower cavity die.
The shape that goes up punch described in the utility model is processed according to the required pipe fitting curved shape of reality, for example in a kind of specific embodiment, the existing automobile front beam that adopts the utility model to make to relate in the background technology, the shape that then goes up punch will be processed to isosceles trapezoid, and the shape of corresponding lower cavity die then is processed into consistent with last punch coupling.
The course of work of the present utility model is as follows:
At first pipe fitting to be processed is lain on the lower cavity die, yet the moving cylinder that starts the left and right sides heads into two alignment pins respectively in the mouth of pipe at pipe fitting two ends and positions.Start the oil pressure lathe subsequently, the feasible last punch of platform drive of going to bed presses down pipe fitting is carried out punching press, and in the process of last punch and lower cavity die matched moulds, pipe fitting and upper and lower cavity fit and can effectively guarantee the stability of pipe fitting, make it be unlikely to double swerve.Along with the matched moulds of last punch and lower cavity die, pipe fitting also is stamped into the shape consistent with last punch, and the moving cylinder of both sides must remain the top power to pipe fitting in this process, guarantees that the pipe fitting position is motionless.When moving back mould, control the platform of going to bed and drive upward punch rising, the moving cylinder of controlling both sides simultaneously withdraws from alignment pin in the mouth of pipe at pipe fitting two ends, and the bend pipe after just punch forming can being finished at last takes off from lower cavity die.
What deserves to be mentioned is that the fixing alignment pin shape of moving cylinder head is decided according to the required pipe fitting orifice configuration of reality in the utility model, makes its double effect of playing profiling in the location.
The utility model advantage is:
1, this bend pipe punch forming device described in the utility model, once finish the brake forming of pipe fitting by the mode of direct punching press, compare back-up sand or oiling molding mode in the existing pipe, process is rapider, working (machining) efficiency is higher, and the good stability of pipe fitting in the process.
2, this bend pipe punch forming device described in the utility model, overall structure is simple, and assembly is few, and low cost of manufacture is fit to apply.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is structural front view of the present utility model (state of punching press pipe fitting);
Fig. 2 is an automobile front beam structural front view.
1, goes up punch; 2, lower cavity die; 3, moving cylinder; 4, alignment pin; 5, upper bolster; 6, die shoe; 7, pipe fitting; 8, automobile front beam.
The specific embodiment
Embodiment: be illustrated in figure 1 as a kind of specific embodiment of the utility model bend pipe punch forming device, it is mainly used to steel pipe fittings 7 is processed into as shown in Figure 2 automobile front beam 8.This device is made of jointly diel and clamping positioning mechanism; Wherein said diel is by being separately fixed on upper bolster 5 and the die shoe 6 and the last punch 1 of form fit and lower cavity die 2 constitute; Described clamping positioning mechanism then by lateral arrangement in ambilateral two moving cylinders 3 of stamping die, and the alignment pin 4 that is fixed on each moving cylinder 3 head together constitutes.
The opposite face of going up punch 1 and lower cavity die 2 described in the present embodiment is a stamping surface, offers the last cavity of applying pipe fitting 7 upper surfaces on the stamping surface of wherein said upward punch 1, and offers the following cavity of applying pipe fitting 7 lower surfaces on the stamping surface of described lower cavity die 2.
