Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to an automatic press equipped with a feeding structure. Background Technology

[0002] Powder metallurgy is a technology that uses metal powder (or a mixture of metal and non-metal powders) as raw materials to manufacture metal materials or products through processes such as molding and sintering. Pressure is applied in a mold (such as cold pressing or hot pressing) to press the powder into a molded part (blank) of the desired shape. In cold pressing, automatic presses are usually used. During automatic pressing, the molded parts that have detached from the mold groove are temporarily placed on the processing table and are generally transferred manually. If the molded parts are not handled promptly, as the number accumulates, workpieces will pile up, reducing the processing table area and increasing the risk of collision damage between the molded parts. Therefore, an automatic press with a pusher structure is provided. Utility Model Content

[0003] The purpose of this invention is to provide an automatic press with a feeding structure to solve the problems mentioned in the background art.

[0022] Please see Figure 1-4 An embodiment of this utility model provides an automatic press with a pushing structure, including a press body 1, a control box 8 installed on one side of the press body 1, a hydraulic cylinder 9 installed at the top of the press body 1, a pressing component 2 installed inside the press body 1, and an upper mold 3 installed at the bottom of the pressing component 2, a platform 5 provided at the bottom of the press body 1, a first push plate 4 provided at the top of the platform 5, a guide groove 10 installed at the top of the first push plate 4, and a hopper 13 provided on one side of the top of the guide groove 10. The hopper 13 is fixed to the top of the support frame 6. A first cylinder 12 is installed inside the support frame 6, and one end of the first cylinder 12 is fixedly connected to the first push plate 4. A second push plate 17 is provided at the front end of the first push plate 4, and a connecting plate 18 is provided at the top of the second push plate 17. A second cylinder 19 is installed at one end of the connecting plate 18 and is installed at the top of the first push plate 4.

[0023] The first push plate 4 has a guide groove 14 inside, and a sleeve 16 is installed inside the guide groove 14. A guide rod 15 is installed on one side of the second push plate 17, and the guide rod 15 passes through the guide groove 14 and the sleeve 16. There are two sets of guide rods 15, and the guide rods 15 are symmetrically distributed on the second push plate 17.

[0024] Specifically, as shown in the figure, during use, the operation of the first cylinder 12 will push the first push plate 4 to move and drive the second push plate 17 to push the molded part away from the position of the molding mold groove 11. The operation of the second cylinder 19, under the cooperation of the guide rod 15 and the guide groove 14, controls the second push plate 17 to push the molded part away from the platform 5. During the powder loading process, the molded part is unloaded and transferred to other equipment to avoid the molded part accumulating on the platform 5.

[0025] The platform 5 has two sets of forming mold grooves 11 inside, and top blocks are installed inside both sets of forming mold grooves 11. Two sets of ejector cylinders 7 are installed at the bottom of the press body 1, and the tops of the two sets of ejector cylinders 7 are fixedly connected to the two sets of top blocks respectively.

[0026] Specifically, as shown in the figure, during use, after the powder raw material is pressed into shape inside the forming mold groove 11 by the upper mold 3, the operation of the ejector cylinder 7 will push the top block to move upward inside the forming mold groove 11, controlling the molded part to be released from the inside of the forming mold groove 11 without damage.

[0027] Working Principle: In operation, firstly, the powder material is poured into the hopper 13. At this time, the first cylinder 12 is in its initial retracted state, and the powder material enters the guide trough 10. The control box 8 starts the automatic press, and the first cylinder 12 extends, pushing the first push plate 4 to move horizontally, moving the guide trough 10 above the forming mold trough 11. Under the action of gravity, the powder material fills the forming mold trough 11, completing the powder loading process. Next, the control box 8 controls the first cylinder 12 to retract, moving the first push plate 4 away from the forming mold trough 11, and controls the hydraulic cylinder 9 to operate, causing the lower pressing component 2 and the upper mold 3 to move downwards, pressing the powder material inside the forming mold trough 11 into shape. After forming, the hydraulic cylinder 9 controls the lower pressing component 2 and the upper mold 3 to reset, and then... The ejector cylinder 7 operates, pushing the top block upwards and moving it upwards inside the forming mold trough 11, controlling the molded part to detach from the inside of the forming mold trough 11 without damage. After the molded part leaves the inside of the forming mold trough 11, the first cylinder 12 extends, pushing the first push plate 4 to move horizontally. The first push plate 4 pushes the molded part away from the top of the forming mold trough 11. The first push plate 4 drives the guide trough 10 to move again to the top of the forming mold trough 11. Under the action of gravity, the powder raw material will fill the forming mold trough 11 again. At the same time, the second cylinder 19 operates, controlling the second push plate 17 to push the molded part away from the carrier 5. During the powder loading process, the molded part is unloaded, so that the molded part is transferred to other equipment, avoiding the accumulation of the molded part on the carrier 5, and finally completing the use of the automatic press.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
