Description

Technical Field

[0001] This utility model relates to the field of mold replacement technology, and in particular to a mechanism for automatically rotating the upper mold of a bending machine mold library by 180°. Background Technology

[0002] When bending workpieces in small batches, the molds need to be changed frequently. Currently, manual mold changing is the most common method, which is time-consuming, increases labor intensity, and greatly increases labor costs. In the current process of automatic mold changing, if the upper mold of some bending machines may need to be reversed according to the bending requirements, if there is no large-angle turning mechanism, the mold direction needs to be changed manually, which is still inefficient. Utility Model Content

[0003] The technical problem this invention aims to solve is that the current bending machine has low efficiency and high cost when changing molds.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic mold changing mechanism for a bending machine, comprising a fixed frame, a rotating mounting body and a mold turning cylinder for controlling the rotating mounting body are mounted on the side wall of the fixed frame, a mold turning transition body is mounted on the side wall of the rotating mounting body, a mold turning connecting body is mounted at the lower end of the mold turning transition body, and a pressing cylinder is symmetrically mounted on both sides of the mold turning transition body via a pressing cylinder mounting plate. A motor and a reducer for controlling the rotation of the mold turning connecting body are fixedly assembled at the upper end of the mold turning transition body.

[0005] The fixed frame sidewall is equipped with left and right positioning cylinders via a base plate mounted on the left and right cylinders. The mold turning and connecting main body has left and right limiting blocks that cooperate with the left and right positioning cylinders fixedly mounted on both sides of the main body.

[0006] The mold turning transition body is internally equipped with a rotating shaft and bearings for connecting the lower output shaft of the reducer to the mold turning connection body.

[0007] The lower end of the mold turning and connecting body is fixedly equipped with a guide connecting base plate and a guide connecting sealing plate.

[0008] The mold turning connection body is fixedly installed with front and rear cylinders, and front and rear cylinder clamping blocks are fixedly installed on the extended ends of the front and rear cylinders.

[0009] A main body rotation limiting mounting plate is installed on the side wall of the fixed frame.

[0010] The beneficial effects of this utility model are:

[0011] (1) The automatic mold changing mechanism of the bending machine mold magazine with 180° upper mold rotation adopts automatic mold changing time, which greatly shortens the time of manual mold changing, significantly reduces time cost, and improves production efficiency.

[0012] (2) When the product is produced in small batches and multiple batches, the mold is changed frequently. The automatic mold changing method is more convenient and efficient.

[0013] (3) To a certain extent, this mechanism makes up for the problem that the automatic mold changing mold library of the traditional bending machine cannot be rotated at a large angle. By jumping 180°, the installation direction of the upper mold can be changed, making the automatic mold changing mold library of the bending machine more perfect. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Figure 1 , Figure 2 , Figure 3 and Figure 4The fixed frame 1 shown is mounted on a crossbeam on one side with a mold turning cylinder 3; two mold turning main body mounting connecting shafts are fixed on one side of the vertical beam with screws, and a rotating mounting main body 2 is rotatably mounted on the mold turning main body mounting connecting shafts. Left and right cylinder adjustment plates are installed on the adjacent side of the vertical beam, and left and right cylinder mounting base plates 10 are installed below the left and right cylinder adjustment plates. A guide transition connecting sealing plate is installed at the bottom of the left and right cylinder mounting base plates 10.

[0022] Left and right positioning cylinders 11 are installed on the left and right cylinder mounting base plate 10. The left and right positioning cylinders 11 are fixed with screws to the left and right cylinder mounting blocks with left and right positioning shafts. The left and right positioning shafts can be positioned and guided by the left and right limit blocks 12 of the connecting body at one end of the mold rotating connecting body 5. The guide connecting sealing plate 16 and guide connecting base plate 15 are installed and assembled below the mold rotating connecting body 5. At the same time, front and rear cylinders 17 are installed behind the mold rotating connecting body 5. The front and rear cylinder transition clamping block with front and rear cylinder clamping block 18 is connected to the extended end of the front and rear cylinders 17 and is set on one side of the mold rotating connecting body 5. The mold turning transition body 4 is equipped with two pressing cylinder mounting plates on both sides, and pressing cylinders 7 are installed on each of them; a pressing cylinder front end plate is installed at the bottom protruding end of the pressing cylinder 7; a positioning block that cooperates with the pressing cylinder front end plate is fixed on the upper end of the mold turning connection body 5, which cooperates with the pressing guide positioning; the front end of the mold turning cylinder 3 is connected to a fish mouth connector, which is locked with the front end connecting block of the mold turning cylinder behind the rotating mounting body 2, so that they can be connected and rotated.

[0023] The automatic die-changing mechanism for bending machines, which rotates the upper die 180°, works in conjunction with a three-axis robot to automatically change the upper and lower dies. The three-axis robot picks up the die from the die fixing frame and places it into the rotating mechanism. When the upper die needs to be reversed for bending, the upper die is slid along the guide transition connecting plate and inserted between the guide connecting plate 16 and the guide connecting base plate 15. Then, the motor 8 drives the die-changing connecting body 5 at the bottom to rotate via the reducer 9. The die-changing connecting body 5 rotates the upper die 180°, thus completing the displacement and replacement.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
