Description

Technical Field

[0001] The present invention relates to the field of forging machines, in particular to a forging machine for mechanical processing. Background Art

[0002] A forging press is a machine used for cold working of metals and machinery. It changes the shape of metal by applying pressure to the metal. There are many types of forging presses, such as roll forging, mechanical press, extrusion, and screw forging.

[0003] Extrusion forging presses are suitable for the production of non-ferrous metals such as aluminum and copper pipes and profiles. Depending on the processing temperature, extrusion forging presses are divided into hot extrusion and cold extrusion. Hot extrusion is mainly used to produce special pipes and profiles, as well as parts that are difficult to form by cold extrusion; while cold extrusion is suitable for mass production of smaller parts.

[0004] For some plate or sheet materials, when using a cold extrusion forging machine for forming, the loading process requires manual delivery of the plate or sheet materials to the forming bottom die position one by one for extrusion forging forming. Due to continuous production and frequent operations, it is not only time-consuming and labor-intensive, but also leads to low production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a forging machine for machining, which can automatically drop a single piece of plate-like material into a forging bottom die under its own gravity without manual operation, thereby improving production efficiency and reducing labor costs, and can solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a forging machine for mechanical processing, comprising a forging table and a feeding mechanism provided on the top, the feeding mechanism comprising a U-shaped plate and a slide, a feeding chute provided on the top of the forging table, the slide is located inside the feeding chute and is slidably connected, the inverted U-shaped plate is fixedly connected to the top of the forging table, the slide is arranged in the U-shaped plate, the slide is a hollow structure, and both the slide and the top of the U-shaped plate are provided with a blanking port, and a forging bottom die is installed on the slide at the blanking port position; a forging mechanism is provided above the U-shaped plate, and a driving mechanism is provided at the bottom of the forging table.

[0007] Preferably, the length of the slide is twice the length of the U-shaped plate, a number of support rods are fixedly connected to the bottom of the forging table, and the U-shaped plate is fixedly connected to L-shaped limit plates at the four corners of the blanking port.

[0008] Preferably, the forging bottom die is rotatably connected to the inside of the slide through several hinges. The slide is provided with a cylinder below the forging bottom die. The bottom of the slide and the bottom of the forging bottom die are fixedly connected with shaft sleeves. The inclined output end of the cylinder is rotatably connected to the bottom shaft sleeve of the forging bottom die through a pin shaft, and the tail end of the cylinder is rotatably connected to another shaft sleeve through a pin shaft.

[0009] Preferably, the forging mechanism includes a top plate, which is fixedly connected to the top of the L-shaped limit plate through two cross beams. A hydraulic cylinder is installed on the top of the top plate, the output end of the hydraulic cylinder slides through the top plate, and the top end is fixedly connected to a forging top die.

[0010] Preferably, a fitting groove is provided on the side surface of one end of the cross beam close to the L-shaped limiting plate, and a reinforcement frame is fixedly connected to the bottom side wall of the other end, and the reinforcement frame is fixedly connected to the adjacent L-shaped limiting plate.

[0011] Preferably, the driving mechanism includes a base box, and two long cavities are embedded in the side of the feeding chute, and several sliders are slidably connected inside the long cavities. Two support shafts are rotatably installed on the two inner side walls of the bottom box, and sprockets are fixedly connected at both ends of the support shafts. The two sprockets on the same horizontal line are connected through a chain transmission.

The top of the slider is fixedly connected to the bottom of the slide, and the bottom is fixedly connected to the top of the chain.

[0012] Compared with the prior art, the beneficial effects of the present invention are: automated loading and improved production efficiency: by setting up the coordinated use of a U-shaped plate, a slide, a blanking port and a forging bottom die, automatic loading of plate-like materials is realized. Driven by a motor, the slide can smoothly and controllably move the forging bottom die to the bottom of the forging mechanism. During the displacement process of the slide, when the two blanking ports are aligned, a single piece of plate-like material automatically falls into the forging bottom die under its own gravity. When the two blanking ports deviate, the remaining material is still set on the surface of the slide, without the need for manual operation, thereby improving production efficiency and reducing labor costs; the forging bottom die can be flipped to facilitate material pouring out: the forging bottom die is rotatably connected to the inside of the slide by a hinge, and is driven by a cylinder to flip. This design enables the forged plate-like material to be easily poured out of the forging bottom die, without the need for manual removal of the formed material, further improving work efficiency.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-6 The figure shows a forging machine for mechanical processing, including a forging table 1 and a feeding mechanism 2 on the top, the feeding mechanism 2 includes a U-shaped plate 201 and a slide 202, a feeding chute 101 is provided on the top of the forging table 1, the slide 202 is located inside the feeding chute 101 and is slidably connected, the inverted U-shaped plate 201 is fixedly connected to the top of the forging table 1, the slide 202 is arranged in the U-shaped plate 201, the slide 202 is a hollow structure, and a blanking port 204 is provided on the top of the U-shaped plate 201, and a forging bottom die 205 is installed on the slide 202 at the position of the blanking port 204; a forging mechanism 3 is provided above the U-shaped plate 201, and a driving mechanism 4 is provided at the bottom of the forging table 1.

[0017] It is worth noting that the plate-like material to be extruded is placed high in the blanking area of ​​the U-shaped plate 201. When in use, by starting the driving mechanism 4, the motor 405 drives the support shaft 403 and the sprocket 402 to rotate, and the sprocket 402 drives the slider 406 to slide inside the long cavity 102 through the chain 404, thereby driving the slide 202 to slide inside the feeding chute 101, so as to facilitate the forging bottom die 205 to be moved to the square of the forging mechanism 3 for forming. The plate-like material can be placed in the blanking port 204 area. In the displacement process of the slide 202, when the two blanking ports 204 are aligned, the single plate-shaped material automatically falls into the forging bottom die 205 due to its own gravity. When the two blanking ports 204 deviate, the remaining material is still set on the upper surface of the slide 202 and stably placed in the blanking port 204 area of ​​the U-shaped plate 201; by setting up the coordinated use of the U-shaped plate 201, the slide 202, the blanking port 204 and the forging bottom die 205, the loading process does not require manual operation, which improves production efficiency and reduces labor costs.

[0018] See also Figure 1 、 Figure 2 and Figure 3 The length of the slide 202 is twice the length of the U-shaped plate 201. Several support rods 103 are fixedly connected to the bottom of the forging table 1. The U-shaped plate 201 is fixedly connected to the four corners of the blanking port 204 with L-shaped limit plates 203. The setting of the L-shaped limit plates 203 can effectively prevent the plate material on the slide 202 from shifting, ensuring the alignment accuracy of the device material, the forging bottom die 205 and the blanking port 204. In addition, the bottom of the forging table 1 is supported and fixed by the support rods 103, ensuring the stability of the overall structure.

[0019] Please refer to Figure 5 and Figure 6 The forging bottom die 205 is rotatably connected to the inside of the slide 202 through several hinges 206. The slide 202 is provided with a cylinder 208 below the forging bottom die 205. The bottom of the slide 202 and the bottom of the forging bottom die 205 are fixedly connected with a shaft sleeve 209. The output end of the inclined cylinder 208 is rotatably connected to the shaft sleeve 209 at the bottom of the forging bottom die 205 through a pin 207, and the tail end of the cylinder 208 is rotatably connected to another shaft sleeve 209 through a pin 207. The extension and contraction of the cylinder 208 can drive the forging bottom die 205 to flip over in the slide 202, so that the forged plate material can be poured out from the forging bottom die 205. There is no need to manually remove the formed material, which further improves work efficiency.

[0020] See Figure 2 、 Figure 3 and Figure 4The forging mechanism 3 includes a top plate 301, which is fixedly connected to the top of the L-shaped limit plate 203 through two crossbeams 304. A hydraulic cylinder 302 is installed on the top of the top plate 301. The output end of the hydraulic cylinder 302 slides through the top plate 301 and is fixedly connected to a forging top die 303 on the top. The forging top die 303 cooperates with the forging bottom die 205 to forge the plate-like material placed on the forging bottom die 205. The extension and contraction of the hydraulic cylinder 302 can drive the forging top die 303 to move up and down to achieve the forging operation on the plate-like material. The design of the top plate 301 not only enhances the stability of the entire forging mechanism, but also provides a stable installation platform for the hydraulic cylinder 302. In addition, the fixed connection between the two crossbeams 304 and the top of the L-shaped limit plate 203 further ensures the stable connection between the forging mechanism 3 and the slide 202, thereby improving the structural stability and safety of the entire device.

[0021] See Figure 2 、 Figure 3 and Figure 4 The crossbeam 304 is provided with a fitting groove 305 on the side near one end of the L-shaped limiting plate 203, and the fitting groove 305 matches the plate-like material. After the plate-like material is put in, it can be just stuck in the fitting groove 305 to achieve preliminary positioning and limiting of the plate-like material, avoiding the displacement or shaking of the plate-like material during the forging process, and further improving the accuracy and stability of the forging. The bottom side wall of the other end is fixedly connected with a reinforcement frame 306, and the reinforcement frame 306 is fixedly connected to the adjacent L-shaped limiting plate 203. This design further enhances the connection strength between the crossbeam 304 and the L-shaped limiting plate 203, and ensures the firmness of the support of the top plate 303.

[0022] See also Figure 4 and Figure 5 The driving mechanism 4 includes a bottom box 401, and two long cavities 102 are embedded in the side of the feeding chute 101. Several sliders 406 are slidably connected inside the long cavities 102. Two support shafts 403 are rotatably installed on the two inner side walls of the bottom box 401. Sprockets 402 are fixedly connected at both ends of the support shafts 403. The two sprockets 402 on the same horizontal line are connected by a chain 404. A motor 405 is installed on the rear side of the bottom box 401. The output end of the motor 405 is fixedly connected to the adjacent support shaft 403. The top of the slider 406 is fixedly connected to the bottom of the slide 202, and the bottom is fixedly connected to the top of the chain 404. When the motor 405 is started, it drives the support shaft 403 connected to it to rotate. This rotational action then drives the two support shafts 403 to rotate synchronously through the transmission mechanism of the sprocket 402 and the chain 404. Since the chain 404 is fixedly connected to the bottom of the slider 406, as the chain 404 moves, the slider 406 slides inside the elongated cavity 102. It is important to note that the top of the slider 406 is fixedly connected to the bottom of the slide 202, which means that the slide 202 can move as the slider 406 slides. This design enables the slide 202 to be driven by the motor 405 and to move back and forth smoothly and in a controlled manner along the direction of the elongated cavity 102, providing precise conveying and positioning functions for the plate-like material, thereby ensuring the smooth progress of the forging operation.
