Description

Technical Field

[0001] This utility model belongs to the technical field of metal forming and processing equipment, and particularly relates to a horizontal stamping equipment. Background Technology

[0002] In modern industrial production, stamping equipment is widely used in many fields such as automobile manufacturing, steel production, electrical machinery, and hardware and plastics, playing a vital role. However, existing stamping equipment faces many problems that urgently need to be solved in actual use. Traditional stamping equipment suffers from difficulties in positioning during die changes. Due to the diversity and complexity of the parts being processed, frequent die changes are required during production to meet the stamping needs of different parts. However, existing equipment lacks an effective positioning mechanism, making the die-changing process cumbersome and time-consuming, affecting production efficiency, and making it difficult to guarantee stamping accuracy and product quality.

[0003] Chinese patent document CN211161712U discloses a flat forging machine for metal forging, including a base a and a fixed column. The fixed column is installed on the upper outer wall of the base a. A frame is provided on the upper outer wall of the base a. A hydraulic cylinder a is provided on the upper outer wall of the frame. A hydraulic rod is provided on the lower outer wall of the frame. A movable die is provided on the lower outer wall of the hydraulic rod. The movable die drives a fixed block to rise together, while a rotating block b inside the fixed block rotates in a movable circular groove. The movable circular groove is arc-shaped, allowing the rotating block b to rotate up and down in the movable circular groove. When the rotating block b moves in the movable circular groove, it is similar to the movement of a compass. Then, the rotating block b drives a pressure plate to rotate downward together. During the downward rotation of the pressure plate, the forging can be pressed down by the pressure plate. This pressing device is similar to the movement of a lever. In this way, through the pressing of the pressure plate, the forging is always on the fixed die.

[0004] In the aforementioned patented solution, a punch positioned on one side of the mold presses into the mold, causing the rollers inside to press and shape the part. However, this method can only be applied to molds with relatively simple structures. Since the workpiece (the heated rollers) in the mold is not a fluid and has limited flowability, when faced with molds with complex structures and high surface quality requirements, especially those with fine structures at the end furthest from the punch, the metal may not completely fill the cavity, or defects such as air bubbles may appear on the surface after pressing, resulting in defective products. While increasing the punch pressure can improve metal flow and reduce the defect rate, as a processing device, it must be adapted to different molds. When processing simpler parts again, increasing the punch pressure obviously increases processing costs. Utility Model Content

[0005] To overcome the technical problem in existing technologies where insufficient punch pressure leads to high defect rates when dealing with molds with complex structures or high surface quality requirements, while increasing punch pressure increases processing costs when switching to simpler molds, this invention aims to provide a horizontal stamping device. By setting a main punch and a secondary punch on both sides of the mold, when dealing with simple molds, only the main punch operates, minimizing costs while fulfilling processing requirements. When dealing with complex or high-requirement molds, the main punch and secondary punch stamp both sides of the mold respectively, with the secondary punch compensating for the insufficient pressure of the main punch, improving processing quality and reducing the defect rate.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a horizontal stamping machine, including a bed; a bed frame, the bed frame being disposed directly above the bed; a lower die, the lower die being disposed at the upper end of the bed; a top hydraulic cylinder, the top hydraulic cylinder being longitudinally disposed at the lower end of the bed frame; an upper die, the upper die being disposed on the moving end of the top hydraulic cylinder, the upper die and the lower die being directly opposite each other; a main punch, the main punch being horizontally slidably connected to the bed; a crankshaft, the crankshaft being rotatably connected to the bed, the crankshaft being drively connected to the main punch; wherein, a secondary punch is horizontally slidably connected to the bed, the secondary punch and the main punch being symmetrically disposed on both sides of the lower die, the sliding directions of the secondary punch and the main punch being coincident; a lateral hydraulic cylinder for driving the sliding of the secondary punch is provided on the bed.

[0007] The pressure directions of the auxiliary punch and the main punch are on the same axis, which helps to protect the structural strength of the equipment and extend its service life.

[0008] Furthermore, a top block is provided at the upper end of the bed, and the top block abuts against the end of the lower die away from the main punch; the auxiliary punch is slidably connected inside the top block, and the auxiliary punch can be selectively slid out from the top block.

[0009] When dealing with simple molds, the top block provides stable support for the lower mold and helps to withstand the enormous pressure from the main punch.

[0010] Specifically, the diameter of the auxiliary punch is smaller than the diameter of the main punch; the maximum pressure value of the top hydraulic cylinder and the maximum pressure value of the main punch are both greater than the maximum pressure value of the side hydraulic cylinder.

[0011] Because the hot melt roller has extremely poor fluidity, and the main punch has already provided enormous pressure to the roller, the end of the lower die away from the main punch will have air bubbles or cavities. The pressure provided by the auxiliary punch can greatly improve the forming quality of the die by simply compacting the metal and expelling the air, and it also consumes less energy.

[0012] Furthermore, a mounting base is provided at the lower end of the moving end of the top hydraulic cylinder, and the upper mold is located at the lower end of the mounting base; a longitudinal sliding groove is horizontally provided through the mounting base; a pressure rod is longitudinally slidably connected in the longitudinal sliding groove, and the two ends of the pressure rod extend from both sides of the longitudinal sliding groove respectively; an extension rod for pushing down the two ends of the pressure rod is provided at the lower end of the bed frame; at least one support rod is provided on the pressure rod, and the support rod can optionally extend to below the upper mold.

[0013] After the stamping is completed, as the upper die moves upward, the formed part may adhere to the upper die. The upper die slides upward, causing the extension rod and the pressure rod to abut against each other at both ends, causing the pressure rod to slide downward relative to the upper die, thereby causing the support rod to push the formed part off the upper die.

[0014] Furthermore, a pad is longitudinally slidably connected to the bed directly below the lower mold; at least one push rod is provided at the upper end of the pad, and the push rod can optionally extend above the lower mold; a bottom hydraulic cylinder for driving the pad to slide is provided on the bed.

[0015] Similarly, the molded parts that adhere to the lower mold also have the problem of being difficult to remove. The bottom hydraulic cylinder can cause the ejector rod to push the molded parts out of the lower mold.

[0016] Further, it includes a positioning disk disposed at one end of the crankshaft; a mounting cover disposed on the bed, with the positioning disk located inside the mounting cover; a positioning notch disposed on the outer periphery of the positioning disk; and a detection port disposed on the outer wall of the mounting cover. The positioning notch contains a limit switch for monitoring the rotational position of the crankshaft, the moving end of which abuts against the outer periphery of the positioning disk. The bottom of the mounting cover contains an encoder for monitoring the rotational angle of the crankshaft, the encoder being directly opposite the positioning disk.

[0017] The encoder and the limit switch are used to detect the movement position of the main punch so as to determine when the auxiliary punch starts to work. The encoder is electronic and the limit switch is mechanical, which improves the stability of the system, helps to reduce the defect rate and improve the processing efficiency.

[0018] Specifically, it includes an eccentric shaft, which is eccentrically mounted on the crankshaft; a sliding box, which is horizontally slidably connected to the bed, and the main punch is located at the end of the sliding box facing the lower mold; and a connecting rod, one end of which is provided with a ball head that is rotatably connected to the sliding box, and the other end of which is provided with a collar that is rotatably connected to the outer circumference of the eccentric shaft.

[0019] Preferably, the upper part of the bed is provided with an inspection door facing the connecting rod; the front end of the bed is provided with a ladder facing the inspection door.

[0020] Specifically, a large gear is provided at one end of the crankshaft; a speed change shaft is rotatably connected to the bed; a small gear that is driven by the large gear is provided at one end of the speed change shaft, and a large pulley is provided at the other end; a clutch is provided on the large pulley; a motor is provided at the upper end of the bed located on one side of the bed frame; the motor is connected to the large pulley by a belt drive.

[0021] Specifically, a sliding part is provided on the moving end of the top hydraulic cylinder; guide rods that are slidably connected to the bed frame are respectively provided on both sides of the sliding part.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model symmetrically arranges a main punch and a secondary punch on both sides of the mold. When dealing with simple molds, only the main punch works, enabling production with lower equipment operating costs. When dealing with complex or high-requirement molds, the secondary punch compensates for the insufficient pressure of the main punch, improving processing quality and reducing the defect rate.

[0024] 2. The auxiliary punch of this utility model is located at the end of the mold away from the main punch. Due to the extremely poor fluidity of the heated roller, after the main punch presses the roller, the end of the mold away from the main punch often cannot completely fill the cavity or has air bubbles on the surface due to insufficient pressure or poor fluidity. The auxiliary punch applies pressure to this position again to improve the quality of the molded product.

[0025] 3. This utility model is equipped with a push rod and a pressure rod. After the product is pressed, the push rod and pressure rod can push the product out of the upper mold or the lower mold respectively, which facilitates the removal of the molded product, shortens the processing cycle of a single part, and improves processing efficiency.

[0026] 4. This utility model is equipped with a limit switch and an encoder to determine the movement position of the main punch based on the rotation of the crankshaft, thereby accurately determining the timing for the auxiliary punch to start working, which helps to improve the quality of the molded products, shorten the processing cycle, and improve processing efficiency.
