Description

Technical Field

[0001] This utility model relates to the field of forging processing technology, specifically to a forging blanking device. Background Technology

[0002] In the forging process, the forging blanking device is a key piece of equipment used to cut raw materials (such as bars, tubes, etc.) into blanks of predetermined dimensions, which directly affects the efficiency and quality of subsequent forging processes. During the conveying of forging raw materials, the centered conveying of the material is a necessary condition for subsequent cutting operations. In the existing blanking devices used for forging processing, the large sliding friction generated when the clamping plate assembly contacts the workpiece will cause the material conveying to be obstructed, making it impossible to simultaneously achieve material conveying and centering limit. In addition, the existing devices lack reliable positioning and discharge mechanisms, and cannot achieve fixed-length cutting and automatic sliding of the cut material blocks, resulting in insufficient accuracy and automation of the device. Therefore, we propose a forging blanking device. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide a forging blanking device with a reliable material conveying unit. This unit can centrally convey forging raw materials on a belt conveyor. The rollers inside the clamping plates limit the material's movement while simultaneously reducing frictional resistance through their own rotation, ensuring smooth material transport. A second hydraulic cylinder drives the mounting frame and cutter to rise and fall. When the mounting frame descends, it clamps and fixes the protruding section of the material, facilitating stable cutting. An industrial camera identifies the light from the LED strip from above and can pinpoint the end of the protruding section of the material. Using the light source of the LED strip as a reference scale, the PLC controller analyzes the image data to determine the length of the material protrusion and pauses the belt conveyor once the material reaches the predetermined cutting length, thus achieving fixed-length cutting. After being cut, the material blocks slide down the inclined slide under their own weight, completing the blanking operation. Two guide frames on the left and right sides center the sliding blocks, allowing for stacking of the continuously sliding blocks, effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a forging blanking device, comprising a main machine tool, a material conveying unit, and a cutting blanking unit; Main machine tool: longitudinally arranged, with an inverted U-shaped mounting bracket fixedly connected to the outer front end; Material conveying unit: includes belt conveyor, mounting side frame, hydraulic cylinder one, clamping plate, auxiliary telescopic rods and rollers. The upper end of the main machine tool is centrally mounted with a longitudinal belt conveyor. An L-shaped mounting side frame is fixedly connected to both the left and right sides of the main machine tool. A hydraulic cylinder one is installed at the middle position of the inner side of the vertical section of the mounting side frame. The telescopic end of the hydraulic cylinder one faces horizontally towards the middle of the device and is fixedly connected to the back of the clamping plate. Two auxiliary telescopic rods are fixedly connected between the clamping plate and the vertical section of the mounting side frame. The two auxiliary telescopic rods are symmetrically distributed on the front and rear sides of the hydraulic cylinder one. A row of rollers is embedded in a linear array on the inward side of the clamping plate. Cutting and blanking unit: installed on the mounting frame.

[0005] The mounting bracket is used for installing the hydraulic cylinder and the auxiliary telescopic rod. The hydraulic cylinder pushes the two clamping plates on the left and right sides to converge in the middle, thereby centering and limiting the conveyed forging material at the middle side of the upper end of the belt conveyor. The belt conveyor is used to transport the forging material. The rollers on the inner side of the clamping plates limit the material while reducing the frictional resistance of the material through their own rotation, ensuring smooth material conveying. The auxiliary telescopic rod can share the weight of the clamping plates with the telescopic rod of the hydraulic cylinder, thus providing a protective effect for the hydraulic cylinder.

[0006] Furthermore, the material conveying unit also includes a material conveying ramp, guide frames, and a clearance groove. The front end of the main machine tool is fixedly connected to the material conveying ramp, and a clearance groove is provided on the upper side of the connection point between the material conveying ramp and the main machine tool. Two folded guide frames are fixedly connected inside the material conveying ramp, with the lower ends of the two guide frames approaching the center. The clearance groove is used to make room for the steel cutter head. The protruding section of the workpiece to be cut extends forward from the material conveying ramp, and after cutting, the material block will slide down the material conveying ramp under its own gravity, thereby completing the unloading operation. The two guide frames can center the sliding material block so as to stack the continuously sliding material block.

[0007] Furthermore, the cutting and blanking unit also includes a mounting slot, a mounting crossbeam, a second hydraulic cylinder, and a fixing frame. The inner sides of the left and right vertical sections of the mounting frame each have a vertical mounting slot. The U-shaped mounting frame houses the mounting crossbeam, which is slidably connected to the mounting slot via locking blocks fixed at both ends. A fixing frame, also inverted U-shape, is fixedly connected to the upper middle position of the mounting frame. The second hydraulic cylinder is fixedly installed inside the fixing frame, with its extension end facing downwards and fixedly connected to the upper middle part of the mounting crossbeam. The mounting slot is used to engage the locking blocks at the end of the mounting crossbeam, allowing the crossbeam to slide smoothly up and down. The fixing frame is used to fix the second hydraulic cylinder, which drives the mounting crossbeam and the cutting tool to rise and fall. When the mounting crossbeam descends, it can press and fix the protruding section of the material, facilitating stable cutting.

[0008] Furthermore, the cutting and blanking unit also includes a ball screw, a movable slide, a steel cutter head, and a motor. The front end of the mounting frame has a transverse mounting groove, inside which a transverse ball screw is installed. The drive motor for the ball screw is embedded inside the mounting frame. The front end of the ball screw nut is fixedly connected to the movable slide, which houses the steel cutter head and the motor. The lower end of the steel cutter head extends downwards and corresponds vertically to the clearance groove. The output shaft of the motor is fixedly connected to the center of the steel cutter head. The ball screw drives the movable slide to move laterally, the motor drives the steel cutter head to rotate, and the movable slide drives the steel cutter head to move horizontally, thereby cutting materials of different widths.

[0009] Furthermore, the cutting and unloading unit also includes an industrial camera and a light strip. The industrial camera is mounted at the lower front position of the movable slide, with its lens facing downwards. A light strip is embedded in the middle of the upper edge of the material conveyor. The industrial camera detects the light from the light strip from above and can identify the end of the material's protruding section. Using the light source of the light strip as a reference scale, the PLC controller can analyze the image data to determine the length of the material protruding and pause the belt conveyor operation after the material reaches the predetermined cutting length, thereby achieving fixed-length cutting of the material.

[0010] Furthermore, it also includes a PLC controller. The PLC controller is mounted on the right side of the mounting bracket. The input terminals of the belt conveyor, hydraulic cylinder one, hydraulic cylinder two, electric motor, industrial camera, LED strip, and ball screw drive motor are all electrically connected to the output terminal of an external power supply through the PLC controller. The PLC controller can support the device to perform fixed-length cutting based on the image data acquired by the industrial camera. It can control the operation and movement of the cutting tool during cutting, and can continue to control the material conveying after cutting is completed, thereby achieving continuous automatic processing.
