Description
Technical Field
[0001] The utility model relates to the technical field of presses, and more specifically, it refers to a door driving mechanism for a hot forming press. Background Art
[0002] Due to its characteristics of high speed and low cost, die processing has gained a wider and wider application in recent years. A press is a device that processes powder materials into formed plates by means of high-temperature pressing. In the actual production of some plates, it is necessary to first put the powder materials into the die, then place the die on the lifting table of the press, and the lifting table presses the die tightly between the lifting table and the top plate, and the plate is formed at high temperature. After the plate is heated and formed, subsequent processing of the plate can only be carried out after the die is cooled. A press is provided with a door that can move up and down. During the heating process, the door is closed to reduce heat loss, and during the cooling process, the door is opened to accelerate the cooling rate. At present, most of the doors of presses are manually opened and closed by workers, which is relatively inconvenient to use. Content of the Utility Model
[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a door driving mechanism for a hot forming press to solve the technical problem that the door of the hot forming press in the prior art needs to be manually opened and closed, resulting in relatively inconvenient use.
[0004] To solve the above technical problems, the utility model provides a door driving mechanism for a hot forming press, which includes a frame, a door, a connecting rod, a roller, a fixed pulley, a steel wire rope, a driving component and two connecting plates. The frame is provided with an accommodating cavity, and the accommodating cavity forms an opening at the front end of the frame. The two connecting plates are connected to the front end face of the frame and are respectively located on the left and right sides of the opening. The left and right ends of the door are respectively slidably connected to the two connecting plates, and the sliding direction is the vertical direction. By moving the door in the vertical direction, the opening is opened or closed. The tops of the two connecting plates are both higher than the top of the frame. The connecting rod is connected between the upper parts of the two connecting plates and is higher than the top of the frame. The roller is rotatably connected to the top of the frame, the fixed pulley is rotatably connected to the connecting rod, one end of the steel wire rope is connected to the roller, and the other end of the steel wire rope is wound around the fixed pulley and then connected to the top of the door. The driving component is connected to the top of the frame and is used to drive the roller to rotate.
[0005] After adopting the above structure, the door driving mechanism for a hot forming press of the utility model has the following advantages: The driving component drives the roller to rotate. When the roller rotates, the steel wire rope is wound around the roller, and then the door moves upward to open the opening; when the driving component drives the roller to rotate in the reverse direction, the steel wire rope wound around the roller is released, and then the door moves downward to close the opening, thus realizing the automatic opening and closing of the door, making it more convenient to use.
[0006] As an improvement, there are two left and right rollers rotatably connected to the top end of the frame, and two left and right fixed pulleys rotatably connected to the connecting rod. There are two steel wire ropes, and the rollers, fixed pulleys and steel wire ropes correspond one by one. With this structure, by setting two steel wire ropes and the corresponding rollers and fixed pulleys, the movement of the door body is made more stable, and it is prevented that the door body falls due to the breakage of one of the steel wire ropes, improving safety.
[0007] As an improvement, there are two left and right hanging rings for connecting to the other ends of the steel wire ropes threadedly connected to the top end of the door body. With this structure, it is convenient to connect the door body to the steel wire ropes, and the structure is simple and the connection is convenient.
[0008] As an improvement, the drive assembly includes a motor, a first bevel gear, a second bevel gear and a transmission shaft. The motor is connected to the top end of the frame. The transmission shaft is rotatably connected to the top end of the frame and the axis of the transmission shaft is arranged along the left and right direction. The two rollers are respectively connected to the left and right ends of the transmission shaft. The output shaft of the motor is connected to the first bevel gear, and the middle of the transmission shaft is connected to the second bevel gear. The first bevel gear meshes with the second bevel gear. With this structure, two rollers are driven to rotate by one motor, the structure is simple and the two rollers can rotate synchronously.
[0009] As an improvement, grooves are provided on each connecting plate and on the end faces facing the other connecting plate. The left and right ends of the door body are respectively slidably connected in the two grooves. With this structure, the door body is limited by the grooves, preventing the door body from separating from the connecting plate and improving the stability of the movement of the door body.
[0010] As an improvement, a jack is provided on the front end face of the frame, and a bolt is inserted into the jack. The bolt is located on the movement path of the door body. When the bottom end of the door body abuts against the bolt, the opening is opened. With this structure, the bolt is inserted in the open state of the door body, and the bolt plays a role in limiting the door body, preventing the door body from falling due to the breakage of the steel wire rope.
[0011] As an improvement, an upper limit sensor and a lower limit sensor are connected to one of the connecting plates. The upper limit sensor is located above the lower limit sensor. A limit rod is connected to the door body. Both the upper limit sensor and the lower limit sensor are located on the movement path of the limit rod. Both the upper limit sensor and the lower limit sensor are electrically connected to the drive assembly. With this structure, when the door body moves upward or downward, when the limit rod touches the upper limit sensor or the lower limit sensor, the drive assembly automatically stops, and the upper limit sensor and the lower limit sensor are used to automatically stop the door body, making it more convenient to use.
[0012] As an improvement, two upper and lower mounting plates are connected to the connecting plate. The upper limit sensor is connected to the upper mounting plate, and the lower limit sensor is connected to the lower mounting plate. Long holes are provided on the mounting plates along the vertical direction, and fixing bolts pass through the long holes and are threadedly connected to the connecting plate. With this structure, the heights of the upper limit sensor and the lower limit sensor are changed by adjusting the height of the mounting plate, so that the height when the door body is opened and closed is adjustable to adapt to different working conditions.
