Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to a press. Background Technology

[0002] A press is a sophisticated and versatile machine that can be widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. Presses are divided into three main categories: screw presses, crank presses, and hydraulic presses, all of which are equipped with a forging ejection device at the bottom.

[0003] Existing equipment, such as CN222742112U, describes a press comprising a base, an upper die mounted on the base, the upper part of the upper die sliding vertically with respect to the base, a pressure mechanism mounted on the base, the upper die moving vertically on the base via the pressure mechanism, a first lower die positioned directly below the upper die, a mounting plate positioned below the first lower die, the bottom of the mounting plate fixed to the top of the base, and slide rails fixedly mounted on both sides of the top of the mounting plate. The first lower die is horizontally slidably mounted on the two sets of slide rails, and a second lower die is positioned to the left of the first lower die, slidably mounted on the top of the two sets of slide rails. A connecting block is fixed between the first and second lower dies. The pressure mechanism includes a guide block and a driving component, with the guide block fixed to the top of the upper die. This invention facilitates manual material handling and improves the working efficiency of the press.

[0004] While the aforementioned device facilitates manual material handling and can improve the working efficiency of the press, it requires workers to run back and forth between the left and right ends during use, increasing worker fatigue. Alternatively, two workers would be needed to operate it, leading to increased labor costs. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that requires workers to run back and forth to load and unload materials, and to propose a press machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a press, comprising a press body, a hydraulic cylinder, a pressure plate, a support leg, and a rotating device. The hydraulic cylinder is mounted on the press body, the pressure plate is fixedly connected to the output end of the hydraulic cylinder, the support leg is fixedly connected to the lower surface of the press body, and the rotating device is disposed outside the press body. The rotating device includes an equipment box disposed outside the press body. A rotating rod is disposed inside the equipment box, one end of the rotating rod is disposed outside the equipment box, and a fixing ring is fixedly connected to the end of the rotating rod disposed outside the equipment box. A connecting arm is fixedly connected to the surface of the fixing ring, and there are four sets of connecting arms arranged circumferentially along the surface of the fixing ring. A mold frame is fixedly connected to the end of the connecting arm away from the fixing ring, and a mold plate is disposed inside the mold frame.

[0007] Furthermore, reinforcing rods are fixedly connected to both sides of the connecting arm, and the side of the reinforcing rod away from the connecting arm is fixedly connected to the mold frame.

[0008] Furthermore, the top and bottom walls of the equipment box are both fixedly connected to bearing seats, and the bearing seats are fixedly connected to the surface of the rotating rod.

[0009] Furthermore, a motor is fixedly connected to the inner bottom wall of the equipment box, a drive gear is fixedly connected to the output end of the motor, a driven gear meshes with the surface of the drive gear, and the driven gear is fixedly connected to the surface of the rotating rod.

[0010] Furthermore, the inner sidewall of the mold frame is provided with a groove, and a baffle is slidably connected to the inner wall of the groove. There are two sets of baffles, and the mold plate is disposed between the two sets of baffles.

[0011] Furthermore, a stop block is slidably connected to the inner wall of the groove, and a bolt is threadedly connected to the inner wall of the mold frame. The stop block is placed on the upper surface of the baffle.

[0012] Furthermore, the stop block is threadedly connected to the bolt, and each set of mold frames is provided with four sets of stop blocks and bolts.

[0013] Furthermore, a lead screw is fixedly connected to the lower surface of the equipment box, and a travel wheel is fixedly connected to the end of the lead screw away from the equipment box. A support sleeve is threadedly connected to the surface of the lead screw, and the support sleeve is disposed outside the travel wheel.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] In this invention, a rotating device is incorporated to reduce the idling time of the press. During operation, the equipment box is pushed in front of the press, and the four support sleeves are adjusted until the traveling wheels are fully inside. Raw material is then placed on the mold plate surface. The motor is then started, driving the drive gear, which in turn drives the driven gear, which in turn drives the rotating rod. The rotating rod drives the fixed ring, which, through the connecting arm and reinforcing rod, rotates the mold frame. The motor is then turned off, and raw material is placed on the second mold plate. This process is repeated until the first mold plate rotates below the pressure plate. The hydraulic cylinder is then activated, pushing the pressure plate down to the mold plate surface and applying pressure to the raw material. After the stamping process is complete, the hydraulic cylinder... The pressure plate is raised, the motor is started, and the second mold plate rotates to below the pressure plate. The hydraulic cylinder and pressure plate are used again for stamping. After the third mold plate rotates to below the pressure plate, the first mold plate rotates to the operator's position. The operator demolds the stamped material and reloads it. When a mold plate needs to be replaced, all bolts on the mold frame are loosened, and the stop block and baffle are removed. A new mold plate is then removed and replaced, and the baffle and stop block are reinserted. The stop block is then secured to the mold frame with bolts. By incorporating a rotating device, the idling time of the press is reduced, improving work efficiency. Furthermore, keeping the operator away from the stamping area prevents hand injuries and ensures operator safety, effectively enhancing the reliability of the equipment. Attached Figure Description

[0030] The effect achieved by the above components is to ensure the stability of the rotation of the rotating rod 52 by setting the bearing seat 513.

[0031] Specifically, a motor 510 is fixedly connected to the inner bottom wall of the equipment box 51, a drive gear 511 is fixedly connected to the output end of the motor 510, a driven gear 512 meshes with the surface of the drive gear 511, and the driven gear 512 is fixedly connected to the surface of the rotating rod 52.

[0032] The effect achieved by the above components is to provide a power source for the rotating rod 52 by setting up a motor 510, a driving gear 511 and a driven gear 512.

[0033] Specifically, the inner wall of the mold frame 55 is provided with a groove 57, and a baffle 58 is slidably connected to the inner wall of the groove 57. There are two sets of baffles 58, and the mold plate 56 is disposed between the two sets of baffles 58.

[0034] The effect achieved by the above components is: the baffle 58 is provided to facilitate the fixing of the mold plate 56.

[0035] Specifically, the inner wall of the groove 57 is slidably connected with a stop 514, the inner wall of the mold frame 55 is threadedly connected with a bolt 515, and the stop 514 is placed on the upper surface of the baffle 58.
