Abstract
Description
Technical Field
[0001] The utility model relates to a bending tool for metal components, in particular to a forming die for a retaining rod. Background Art
[0002] In the field of metal processing, bending of metal components such as round rods is a common processing form. When bending rods, different components require different bending angles. Some are 90 degrees, some are 135 degrees, and some are 60 degrees. The bending angles of such components are relatively easy to achieve, so a relatively common bending machine can be used.
[0003] However, in the production process of hydraulic supports, a retaining rod is used, and the end of the retaining rod needs to be bent to form an end corner of 180 degrees. There are many problems with this kind of retaining rod, such as short bending length, large bending angle, and relatively hard bending material. Ordinary bending tools do not have enough bending force, and the retaining rod is prone to deformation, and qualified components cannot be bent out. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a forming die for a retaining rod that can be used in cooperation with a press to bend the end of the retaining rod to form a 180-degree bending angle.
[0005] To solve the above technical problems, the technical solution of a forming die for a retaining rod in the utility model is as follows:
[0006] A forming die for a retaining rod includes an upper die for connecting with the press head and a lower die for connecting with the press workbench. The lower die includes a lower die base, and at least one lower die bending unit is arranged on the lower die base. The lower die bending unit includes a bending vertical plate with a plate thickness extending in the left-right direction. A vertically arranged bending groove is arranged at the upper end of the bending vertical plate. A front-side bending roller and a rear-side bending roller with a rotation axis extending in the left-right direction are rotatably assembled on the front and rear sides of the bending groove at the upper end of the bending vertical plate. The outer peripheries of the front-side bending roller and the rear-side bending roller have roller grooves adapted to the outer periphery of the retaining rod. The upper die includes an upper die base, and an upper die bending unit corresponding to the number of lower die bending units is arranged on the upper die base. The upper die bending unit includes a bending rod with an axis extending in the left-right direction for pressing down the retaining rod. The front-side bending roller and the rear-side bending roller are symmetrically arranged on the front and rear sides of the bending rod. The sum of the diameter of the bending rod and twice the diameter of the retaining rod is equal to the distance between the roller grooves of the front-side bending roller and the rear-side bending roller.
[0007] Further, the bending vertical plate includes a left-side bending vertical plate and a right-side bending vertical plate arranged at intervals in the left-right direction. The wheel shafts of the front-side bending roller and the rear-side bending roller are respectively rotatably assembled on the left-side bending vertical plate and the right-side bending vertical plate.
[0008] Further, the bending groove is a U-shaped groove with an upward opening.
[0009] Further, a baffle bending length positioning block capable of moving back and forth for adjustment is connected to the upper ends of the left bending vertical plate and the right bending vertical plate by bolts.
[0010] Further, there are two lower die bending units, and the two lower die bending units are arranged at intervals left and right.
[0011] Further, the upper die base includes an upper die base plate whose plate thickness extends in the front-rear direction, and two bending rods are fixed to the left and right ends at the bottom of the upper die base plate.
[0012] Further, reinforcing vertical plates are fixed to the front and rear sides of the upper die base plate.
[0013] The beneficial effects of the present utility model are as follows: When the present utility model is in use, the upper die is fixed to the pressure head of the press, the lower die is fixed to the workbench of the press, the baffle to be bent is placed above the front bending roller and the rear bending roller. The pressure head of the press descends, the bending rod descends, and the bending rod pushes the baffle to make the baffle bend and deform. The baffle parts on the front and rear sides of the bending rod are in rolling contact with the roller grooves of the front bending roller and the rear bending roller, reducing the bending resistance of the baffle during the bending process. As the bending rod descends, the bent baffle enters the bending groove. Since the sum of the diameter of the bending rod and twice the diameter of the baffle is equal to the distance between the roller grooves of the front bending roller and the rear bending roller, the end of the bending rod will bend out a 180-degree bending corner. The present utility model utilizes the cooperation of the press and the baffle forming die to achieve the purpose of bending a 180-degree bending angle at the end of the baffle.

[0021] An embodiment of a retaining bar forming die in the present invention is as Figures 1 to 3 shown:
[0022] It includes an upper die 1 for connecting with the press ram and a lower die 2 for connecting with the press workbench. The lower die includes a lower die base. Two lower die bending units 3 are arranged on the lower die base at intervals in the left - right direction. The two lower die bending units can bend two retaining bars simultaneously. The lower die bending unit 3 includes a bending vertical plate with a plate thickness extending in the left - right direction. In this embodiment, the lower die base includes a horizontally arranged lower die base plate 17. The bending vertical plate includes a left bending vertical plate and a right bending vertical plate arranged at intervals in the left - right direction. Bending vertical plate grooves are formed on the lower die base plate, and the left bending vertical plate and the right bending vertical plate are respectively welded and fixed in the corresponding bending vertical plate grooves.
[0023] A vertically arranged bending groove 16 is provided at the upper end of the bending vertical plate. The bending groove 16 is a U - shaped groove with an opening facing upwards. A front bending roller 15 and a rear bending roller 7 with a rotation axis extending in the left - right direction are rotatably assembled on the front and rear sides of the bending groove at the upper end of the bending vertical plate. The outer circumferences of the front bending roller 15 and the rear bending roller 7 have roller grooves 8 adapted to the outer circumference of the retaining bar.
[0024] Specifically, the left and right ends of the axle of the front-side bending roller 15 and the rear-side bending roller 7 are respectively rotatably assembled on the left-side bending vertical plate 5 and the right-side bending vertical plate 6. The upper die includes an upper die base, and an upper die bending unit with the same number as the lower die bending units is arranged on the upper die base. The upper die bending unit includes a bending rod 12 whose axis extends in the left-right direction and is used to press down the stop bar 18. The bending rod 12 is a cylindrical bending rod, and the stop bar 18 to be bent is also cylindrical. The bending rods of two lower die bending units are fixed to the left and right ends of the upper die base through a connecting plate.
[0025] The upper die base includes an upper die base plate 13 whose plate thickness extends in the front-rear direction.

[0026] In the upper die bending unit and the corresponding lower die bending unit, the front-side bending roller 15 and the rear-side bending roller 7 are symmetrically arranged on the front and rear sides of the bending rod 12, and the diameter of the bending rod + twice the diameter of the stop bar = the distance between the roller grooves of the front-side bending roller and the rear-side bending roller.
[0027] The upper ends of the left-side bending vertical plate and the right-side bending vertical plate are connected with a stop bar bending length positioning block 11 that can be adjusted to move back and forth through bolts 10. The upper ends of the left-side bending vertical plate and the right-side bending vertical plate are provided with a plurality of threaded holes spaced along the front-rear direction. During use, by matching the bolts with different threaded holes, the stop bar bending length positioning block can be fixed to different front-rear positions. The operator presses the front end of the stop bar to be bent against the stop bar bending length positioning block, and thus determines the required bending length of the end of the stop bar. The bending rod descends along with the ram of the press, the bending rod presses the stop bar, and the stop bar bends between the front-side bending roller and the rear-side bending roller, and finally bends out a bending angle of 180 degrees.
