Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of alloy slab forging equipment, and in particular relates to a difficult-to-deform high-temperature alloy slab forging device. Background Art
[0002] Difficult-to-deform high-temperature alloys refer to alloy materials that can maintain good strength and durability in high-temperature environments. These alloys are usually used in key components in industries such as aviation, aerospace, and power generation.
[0003] When processing difficult-to-deform high-temperature alloys, it is often necessary to perform multiple forgings on the slab to ensure a uniform distribution of the internal lattice structure of the slab. During forging, the forging head needs to be directed directly at the slab. However, the existing forging device for difficult-to-deform high-temperature alloy slabs lacks reliable fixing components, which causes the slab to move when the forging head presses down on the slab, resulting in a decrease in the uniformity of the internal lattice of the slab, affecting the quality of the final product. Utility Model Content
[0004] The purpose of the present utility model is to solve the problem in the above-mentioned background technology that the current difficult-to-deform high-temperature alloy slab forging device lacks a fixed facing component for the slab. A new difficult-to-deform high-temperature alloy slab forging device is proposed herein, which can make the forging head face the slab and fix the slab during forging to prevent the slab from moving under force.
[0005] A technical solution adopted to achieve the above-mentioned purpose is a forging device for a hard-to-deform high-temperature alloy slab, the hard-to-deform high-temperature alloy slab forging device comprising:
[0006] A frame, wherein a forging table is provided in the frame, and two slide grooves are provided on the forging table;
[0007] A forging unit, comprising a hydraulic cylinder and a pressing plate, wherein the hydraulic cylinder is disposed on the top of the frame, and an output end of the hydraulic cylinder passes through the top wall of the frame and is fixedly connected to the pressing plate;
[0008] A fixing unit, which includes a first clamping block, a second clamping block, two connecting rods, a two-way cylinder, a connecting plate and two springs. The first clamping block and the second clamping block slide in cooperation with the slide groove. One end of the connecting rod is fixedly connected to the first clamping block, and the other end of the connecting rod passes through the second clamping block and is fixedly connected to the connecting plate. The connecting rod is slidably connected to the second clamping block. The two ends of the two-way cylinder are respectively connected to the second clamping block and the connecting plate. The spring is sleeved on the outside of the connecting rod, and the two ends of the spring are respectively connected to the first clamping block and the second clamping block.
[0009] In the above technical solution, the movement of the first clamp and the second clamp is controlled by a bidirectional cylinder to achieve the fixation and release of the slab. The bidirectional cylinder can make the first clamp and the second clamp move toward each other, pushing the slab toward the center of the forging table and clamping it. At this time, the pressure plate is just facing the slab, forging the slab to make the internal lattice of the slab more uniform.
[0010] Furthermore, the forging unit further comprises a plurality of limit rods, both ends of which are fixedly connected to the top wall and the bottom wall of the frame respectively, and the limit rods are slidably connected to the pressure plate.
[0011] In the above technical solution, the moving track of the pressing plate is restricted by the limiting rod, so that the pressing plate follows a predetermined track when pressed down, ensuring that the pressing plate faces the slab.
[0012] Furthermore, the pressure plate includes a limiting plate and a forging head, the forging head is fixed to the bottom of the limiting plate, and the limiting rod is slidably connected to the limiting plate.
[0013] Furthermore, the forging unit is provided with four limit rods, and the limit rods are located at the four corners of the frame.
[0014] Furthermore, the pressing plate is located directly above the forging table, and the first clamping block and the second clamping block are symmetrically arranged relative to the center of the forging table.
[0015] In the above technical solution, the symmetrical arrangement enables the first clamping block and the second clamping block to move evenly in opposite directions under the action of the spring, pushing the slab to move toward the center of the forging table.
[0016] Furthermore, the two connecting rods are located on both sides of the forging table and are lower than the top surface of the forging table.
[0017] In the above technical solution, the connecting rods are arranged on both sides of the forging table to prevent direct contact with the slab and damage to the device.
[0018] Furthermore, a heating block is provided in the forging table, and an electromagnetic coil is provided around the heating block.
[0019] In the above technical solution, the heating block is heated by the electromagnetic coil, and the heat is then transferred to the slab to prevent the temperature of the slab from dropping too quickly.
[0020] Furthermore, heat insulation plates are provided around the sides and bottom of the electromagnetic coil.
[0021] In the above technical solution, the provision of the heat insulation plate prevents heat from escaping from the surrounding side of the forging table, thereby avoiding heat waste.
[0022] Furthermore, the heating block is located directly below the pressing plate.
[0023] In the above technical solution, the heating block can evenly heat the slab located in the center.
[0024] The advantages of the present invention are:
[0025] 1. The utility model sets a fixing unit so that the first clamping block and the second clamping block move toward the center of the forging table under the action of the spring, thereby clamping and fixing the slab directly under the pressure plate, so that the slab is stable during forging and the forging head can face the slab directly.
[0026] 2. The utility model heats the heating block through the electromagnetic coil to conduct heat to the slab, slowing down the cooling speed of the slab, and provides a heat insulation plate to prevent heat from escaping, thereby ensuring the temperature of the slab during forging and enabling forging to proceed more smoothly.
