Description

Technical Field

[0001] This utility model relates to the field of screw press technology, and in particular to an electric screw press for expanding and forging device. Background Technology

[0002] In modern industrial production, forging, as a crucial metal processing method, plays an indispensable role in manufacturing high-quality mechanical parts, aerospace components, and key automotive components. Hole-expanding forging, a key step in the forging process, aims to enlarge the diameter or shape of existing blanks to meet specific product design requirements. Electric screw presses, with their versatility, simple structure, convenient adjustment and maintenance, and high forging precision, are widely used in hole-expanding forging.

[0003] In the process of expanding holes in metal sheets, a screw press can drive a punching head to punch the sheet and create holes. In the existing technology, traditional screw presses have significant drawbacks. For example, when the workpiece is on the punching table, waste material will remain on the worktable during punching, requiring manual removal later. Therefore, this utility model proposes an electric screw press for expanding holes and forging device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an electric screw press for expanding and forging device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric screw press forging device includes a base, a fixed frame fixedly connected to the upper end of the base, two symmetrically arranged sliding grooves on the upper surface of the base, a clamping mechanism for clamping the workpiece is provided in both sliding grooves, a blanking plate fixedly connected to the upper end of the base, an opening on the rear side of the blanking plate, and an inclined surface on the inner bottom of the blanking plate, slide rails fixedly connected to the inner walls of both ends of the fixed frame, sliders slidably connected to both slide rails, a moving plate fixedly connected between the two sliders, a punching head installed at the lower end of the moving plate, and a moving mechanism for moving the moving plate is provided on the fixed frame.

[0007] Preferably, the clamping mechanism includes two clamping plates that are slidably connected in two grooves, and a double-ended threaded rod is rotatably connected between the inner walls of the two ends of the two grooves. The double-ended threaded rod passes through the two clamping plates and is threadedly connected to them.

[0008] Preferably, a second motor is fixedly connected to the side wall of the base, and the end of the output shaft of the second motor is fixedly connected to the end of the double-threaded rod.

[0009] Preferably, the moving mechanism includes a screw that is rotatably connected through the upper end of the fixed frame, and a turntable is coaxially fixedly connected to the upper end of the screw, with a gear ring fixedly sleeved on the turntable.

[0010] Preferably, a movable block is fixedly connected to the upper end of the movable plate, and a screw hole is opened at the upper end of the movable block. The screw is inserted into the screw hole and threadedly connected to it.

[0011] Preferably, a first motor is fixedly connected to the upper end of the fixing frame, and a gear that meshes with a gear ring is fixedly connected to the end of the output shaft of the first motor.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting a blanking plate, when punching, the sheet metal is placed on the upper part of the blanking plate and fixed by the clamping mechanism. When punching, the waste material punched down by the punching head enters into the blanking plate and slides out from the inclined surface of the blanking plate, realizing the discharge of waste material without manual cleaning, which can greatly improve processing efficiency.

[0014] 2. By setting up a clamping mechanism, the sheet metal is placed on the upper part of the blanking plate, and the output shaft of the second motor is driven to rotate, which drives the double-headed threaded rod to rotate, thereby driving the two clamping plates connected to it to move towards the middle, so as to clamp the sheet metal on the blanking plate, limit the position of the sheet metal, and improve the stability of the sheet metal processing.

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Reference Figure 1-7 An electric screw press forging device includes a base 1, a fixed frame 2 fixedly connected to the upper end of the base 1, and two symmetrically arranged slide grooves 16 on the upper end surface of the base 1. A clamping mechanism for clamping the workpiece is provided in both slide grooves 16. The clamping mechanism includes two clamping plates 15 slidably connected in the two slide grooves 16 respectively. A double-ended threaded rod 7 is rotatably connected between the inner walls of the two ends of the two slide grooves 16. The double-ended threaded rod 7 passes through the two clamping plates 15 and is threadedly connected to them. A second motor 17 is fixedly connected to the side wall of the base 1. The output shaft end of the second motor 17 is fixedly connected to the end of the double-ended threaded rod 7. The threads at both ends of the double-ended threaded rod 7 are in opposite directions. When rotating, the clamping plates 15 threaded to it on both sides can move in opposite directions.

[0025] Specifically, a feeding plate 4 is fixedly connected to the upper end of the base 1. An opening is provided on the rear side of the feeding plate 4, and a slope 401 is provided on the inner bottom of the feeding plate 4. Slide rails 10 are fixedly connected to the inner walls of both ends of the fixing frame 2. Sliding blocks 11 are slidably connected to both slide rails 10. A moving plate 9 is fixedly connected between the two sliding blocks 11. A punching head is installed at the lower end of the moving plate 9. Figure 5 As shown, the inclined plane 401 allows the waste to slide out, thus cleaning up the waste.

[0026] Specifically, the fixed frame 2 is provided with a moving mechanism for moving the movable plate 9. The moving mechanism includes a screw 12 that is rotatably connected to the upper end of the fixed frame 2. The upper end of the screw 12 is coaxially fixedly connected to a turntable 3. A gear ring 8 is fixedly sleeved on the turntable 3. The upper end of the fixed frame 2 is fixedly connected to a first motor 6. The output shaft end of the first motor 6 is fixedly connected to a gear 5 that meshes with the gear ring 8.

[0027] Specifically, a movable block 13 is fixedly connected to the upper end of the movable plate 9. A screw hole 14 is opened at the upper end of the movable block 13, and the screw rod 12 is inserted into the screw hole 14 and threadedly connected to it.

[0028] In use, the sheet material is placed on the upper end of the blanking plate 4. The output shaft of the second motor 17 is driven to rotate, which in turn drives the double-headed threaded rod 7 to rotate. This causes the two clamping plates 15, which are threaded to it, to move towards the center, thus clamping the sheet material on the blanking plate 4. This clamping action improves the stability of the sheet material during processing. During punching, the output shaft of the first motor 6 is driven to rotate, which in turn drives the gear 5 to rotate. This in turn drives the gear ring 8, which meshes with the gear ring 8, to rotate. The rotation of the gear ring 8 drives the turntable 3 to rotate, which in turn drives the screw 12 to rotate. The screw 12 rotates within the screw hole 14 and is threadedly connected to the screw hole 14. This causes the moving block 13 to move downward, which in turn drives the moving plate 9 to move downward. This causes the punching head to move downward to punch the sheet material. The waste material punched by the punching head enters the blanking plate 4 and slides out from the inclined surface 401 of the blanking plate 4, thus discharging the waste material without the need for manual cleaning, which greatly improves processing efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
