Description

Technical Field

[0001] This utility model relates to the field of pressure forming technology, specifically to a flange angled ejector tool for a press. Background Technology

[0002] A press is a mechanical device used for processing, forming, and compressing materials, and is widely used in industrial production. Based on the power transmission method, it can be classified as follows: Mechanical press: Converts the rotary motion of an electric motor into the linear reciprocating motion of a slider through a crank-slider mechanism. It has a simple structure, smooth operation, and reliable performance, and is widely used in stamping, extrusion, forging, and powder metallurgy processes. Hydraulic press: Uses a liquid (usually hydraulic oil) as the working medium, transmitting pressure according to Pascal's principle. Its advantages include high pressure, low noise, and suitability for high-load applications. Pneumatic press: Uses compressed air as a power source, featuring simple operation and low cost. Servo press: Uses a servo motor to drive a high-precision ball screw for precision pressure assembly operations. Its characteristics include high precision and high flexibility, making it suitable for precision press fitting.

[0003] However, when the press extrudes and forms the workpiece flange, it needs to support the bottom of the flange. The existing support methods all use multiple support blocks and are driven by hydraulic cylinders, which is costly. Utility Model Content

[0004] The purpose of this invention is to solve the above problems and provide a flange inclined ejector tooling for a press, which supports the workpiece flange through multi-stage movement and has low cost.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A flanged angled ejector tooling for a press includes a base, a lower die for supporting a workpiece disposed on the base, an upper die for pressing the workpiece disposed on the base and moving up and down on the base, a movable block disposed on the base and moving left and right on the base, a support block disposed at the left end of the movable block, and a lifting block disposed on the support block and moving on the support block. The upper end of the support block is an inclined surface that slopes downward from right to left.

[0007] Furthermore, the movable block is connected to the base via a guide rail slider.

[0008] Furthermore, the moving block is provided with an inclined first guide hole, and the upper mold is provided with a drive rod that cooperates with the first guide hole.

[0009] Furthermore, a first compression spring is provided between the left end of the moving block and the lower mold.

[0010] Furthermore, the inclined surface of the lifting block is provided with a slide rail, and the support block is provided with a groove that cooperates with the slide rail.

[0011] Furthermore, the lifting block and the moving block are connected by a connecting mechanism.

[0012] Furthermore, the connecting mechanism includes a second guide hole, a slide rod whose right end extends into and slides within the second guide hole, and a second compression spring disposed on the slide rod. The axis of the second guide hole is parallel to the upper inclined surface of the support block, and the left end of the slide rod is threadedly connected to the lifting block.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model includes a movable block disposed on the base and moving left and right on the base, a support block disposed on the left end of the movable block, and a lifting block disposed on the support block and moving on the support block. The upper end of the support block is an inclined surface sloping downward from right to left. When the movable block moves to the left, the left end of the lifting block first contacts the vertical part of the workpiece supported on the lower die. Then, the movable block continues to move to the left. Under the action of the inclined surface, the lifting block slides on the inclined surface, thereby realizing the lifting block's rise. The upper left corner of the lifting block is tightly fitted with the bottom of the workpiece flange. When the upper die descends, the workpiece is extruded and formed. The workpiece flange is supported by a multi-stage movement method, eliminating the need for multiple drive mechanisms and reducing costs. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] like Figure 1 and Figure 2 As shown, a flange-mounted ejector tooling for a press includes a base 1, a lower die 3 mounted on the base 1 for supporting a workpiece 2, an upper die 4 mounted on the base 1 and moving up and down on the base 1 for extruding the workpiece 2, a movable block 5 mounted on the base 1 and moving left and right on the base 1, a support block 6 mounted on the left end of the movable block 5, and a lifting block 7 mounted on the support block 6 and moving on the support block 6. The upper end of the support block 6 is an inclined surface sloping downwards from right to left. When the movable block 5 moves to the left, the left end of the lifting block 7 first contacts the vertical part of the workpiece supported on the lower die 3. Then, as the movable block 5 continues to move to the left, the lifting block 7 slides on the inclined surface under the action of the inclined surface, thereby realizing the lifting block 7's rise. The upper left corner of the lifting block 7 is tightly fitted with the bottom of the flange of the workpiece 2. When the upper die 4 descends, the workpiece is extruded and formed. The workpiece flange is supported by a multi-stage movement method, eliminating the need for multiple drive mechanisms and reducing costs.

[0021] like Figure 1 As shown, the movable block 5 is connected to the base 1 via a guide rail slider.

[0022] like Figure 2 As shown, the movable block 5 is provided with an inclined first guide hole 8, and the upper mold 4 is provided with a drive rod 9 that cooperates with the first guide hole 8. The first guide hole 8 is inclined to the right from top to bottom, and the axis of the drive rod 9 overlaps with the axis of the first guide hole 8. When the upper mold 4 descends, the movable block 5 moves to the left under the action of the drive rod 9 and the first guide hole 8. No separate drive mechanism is needed to drive the movable block 5, resulting in low cost.

[0023] like Figure 2 As shown, a first compression spring 10 is provided between the left end of the moving block 5 and the lower mold 3. The left end of the moving block 5 is provided with a groove that cooperates with the first compression spring 10, and the position of the first compression spring 10 is positioned by the groove. When the upper mold 4 is lifted, the drive rod 9 gradually separates from the first guide hole 8. With the elastic force of the first compression spring 10, the moving block 5 moves to the right and resets.

[0024] like Figure 2As shown, the inclined surface of the lifting block 7 is provided with a slide rail, and the support block 6 is provided with a groove that cooperates with the slide rail.

[0025] like Figure 2 As shown, the lifting block 7 and the moving block 5 are connected by a connecting mechanism. The connecting mechanism includes a second guide hole 11, a slide rod 12 whose right end extends into and slides within the second guide hole 11, and a second compression spring 13 mounted on the slide rod 12. The axis of the second guide hole 11 is parallel to the upper inclined surface of the support block 6. The left end of the slide rod 12 is threadedly connected to the lifting block 7, the left end of the second compression spring 13 is connected to the lifting block 7, and the right end of the second compression spring 13 is connected to the moving block 5. When the lifting block 7 moves on the upper inclined surface of the support block 6, the slide rod 12 slides within the second guide hole 11, and the second compression spring 13 is compressed. When the moving block 5 moves to the right, under the elastic force of the second compression spring 13, the lifting block 7 moves to the left and downwards on the upper inclined surface of the support block 6, allowing the upper end of the lifting block 7 to separate from the lower end of the workpiece.
