Description

Loading machine brake oil pipe protection plate pressing device

Technical Field

The utility model relates to a loader braking oil pipe protection plate suppression device belongs to loader braking technical field. The utility model discloses in, press the device to be defined as upper and lower direction according to moulding-die module direction of motion, the moulding-die module is from top to bottom the suppression motion.

Background

The brake oil pipe protection plate is an important component in a loader working mechanism, most of places applied by the loader are sand and stone fields with complex working conditions, construction sites and the like, and foreign matters often fall around vehicles or hard objects such as sand and stone rolled in the driving process of the vehicles bounce. Once the foreign matters are smashed on the brake oil pipe, oil leakage of the oil pipe can be caused, so that the brake failure of the loader is caused, and accidents are caused. The protection plate is used for protecting the brake oil pipe from being damaged by falling objects above and hard objects bouncing up on the ground. The protection shield is bent through both ends and is assembled on the drive axle fixing seat. In the processing process, the parallelism requirement of the end faces of two sides bending formed after the protection plate is bent is higher, the bending angle after pressing is required to be ensured to be in a corresponding range, and the angle positions of the two ends are not distorted. The existing processing method is finished by bending and forming twice. One side of the workpiece is bent and formed, and then the other side of the workpiece is turned around and bent, so that the whole machining process is completed. When one side is bent and formed and then turned around and the other side is bent, the bending angle of the protection plate needs to be repeatedly corrected in order to ensure that the bent angle of the two sides is within a certain range. How to properly align is difficult, tedious and time-consuming and labor-consuming. And the parallelism of the two sides is difficult to ensure in a certain range after bending, so that the finished product cannot reach the size range of the use requirement, and finally the assembly cannot be carried out.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1-6, a loader brake oil pipe protection plate pressing device comprises a die upper die mounting plate 1, a die upper module 2, a positioning pin 3, a die lower module 4 and a die lower die mounting plate 5; the top end surface of the upper die mounting plate 1 of the pressing die is provided with fixing screw mounting through holes, and the upper die block 2 of the pressing die is fixedly connected to the bottom end surface of the upper die mounting plate 1 of the pressing die by cylindrical head fixing screws 7 through the fixing screw mounting through holes; the bottom end face of the lower die mounting plate 5 is also provided with fixing screw mounting through holes, and the lower die module 4 is fixedly connected to the upper end face of the lower die mounting plate 5 through the fixing screw mounting through holes by using cylindrical head fixing screws 7. The both sides of the bottom end face of the die mounting plate 1 on the pressing die are downwards connected with positioning pins 3, the both sides of the upper end face of the die mounting plate 5 on the pressing die are respectively provided with through holes, and the positioning pins 3 are arranged in the through holes on the both sides of the die mounting plate 5 in a penetrating way. The upper die mounting plate 1 and the upper die module 2 of the pressing die form an upper die assembly, and the lower die mounting plate 5 and the lower die module 4 of the pressing die form a lower die assembly; the lower die surface of the upper die assembly corresponds to the upper die surface of the lower die assembly, a gap which is adaptive to the forming curvature of the braking oil pipe protection plate 6 is arranged between the two opposite surfaces, and the curvature of the gap is equal to the sum of the change correction value of the curvature of the pressed braking oil pipe protection plate 6 and the curvature caused by the yield strength of the braking oil pipe protection plate.
