Description
Technical Field
[0001] The utility model relates to the technical field of presses, and particularly to a door driving mechanism for a sheet hot forming press. Background Art
[0002] Due to its characteristics of high speed and low cost, die processing has been increasingly widely applied in recent years. A press is a device that processes powder materials into formed sheets by means of high-temperature pressing. In the actual production of some sheets, the powder materials need to be first placed inside the die, and then the die is placed on the lifting table of the press. The lifting table presses the die tightly between the lifting table and the top plate, and the sheet is formed at high temperature. After the sheet is heated and formed, subsequent processing of the sheet 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 dissipation, 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. After the door is opened upward, the door lock on the frame needs to be toggled to keep the door in the open state. However, after the door is opened upward, its height is relatively high, and the position of its door lock is also relatively high. Moreover, both locking and unlocking require workers to toggle the high-position door lock, which is very inconvenient to use, thus causing inconvenience in the use of the press. Summary 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 sheet hot forming press to solve the technical problem that the door lock of the existing press is relatively high, resulting in inconvenient use of the press.
[0004] To solve the above technical problem, the utility model provides a door driving mechanism for a sheet hot forming press, which includes a frame, a door, a counterweight, a fixed pulley, a fixing component, a steel wire rope, a stop bar and two connecting plates. An accommodation cavity is arranged inside the frame, and the accommodation cavity forms an opening at the front end of the frame. The two connecting plates are both connected to the front end of the frame and are respectively located on both 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. The opening is opened or closed by moving the door. A fixed pulley is rotatably connected to the top end of the frame. One end of the steel wire rope is connected to the top end of the door, and the other end of the steel wire rope is wound around the fixed pulley and then connected to the counterweight, so that the counterweight is suspended at the rear side of the frame. The counterweight makes the door move upward to open the opening. The stop bar is connected to the front end face of the frame and is located on the moving path of the upward movement of the door. The fixing component is connected to the lower part of the frame and is used to fix the door and the frame when the opening is closed.
[0005] After adopting the above structure, the door body driving mechanism of the hot forming press for plates of the present utility model has the following advantages: when the door body moves upward, the opening is opened; when the door body moves downward, the opening is closed. Due to the arrangement of the counterweight, the counterweight causes the door body to move upward. Therefore, when the door body is in the open state, the counterweight will cause the door body to have a tendency to move upward, and the door body is blocked by the stop bar from moving upward continuously. At this time, the door body can be kept in a force balance state, and there is no need to additionally set a high-position door lock to prevent the door body from descending when the door body is in the open state at a high position. That is, the worker no longer needs to toggle the high-position door lock to keep the door body in the open state, making it more convenient to use. When the door body is in the closed state, to prevent the door body from moving upward under the action of the counterweight, the door body is fixed at a low position by the fixed component at a low position. When unlocking is required, the worker only needs to unlock the fixed component at a low position, making the use of the press more convenient.
[0006] As an improvement, the fixed component includes a connecting block, a limiting block and a limiting spring. The connecting block is connected to the lower part of the front end face of the frame. The limiting block is slidably connected in the connecting block in the front-rear direction. A limiting spring is connected between the front end of the limiting block and the connecting block. The limiting spring causes the rear end of the limiting block to protrude outside the connecting block. The rear end of the limiting block is provided with an inclined surface, and the inclined surface is located on the moving path of the door body. The front end face of the door body is provided with a limiting groove for the rear end of the limiting block to be inserted into. When the door body moves downward and the lower end of the door body abuts against the inclined surface, the limiting block moves forward; adopting this structure, when the door body moves downward, due to the arrangement of the inclined surface, the limiting block will automatically move forward. After the door body continues to move downward for a certain distance, the limiting block corresponds to the limiting groove and the limiting block is inserted into the limiting groove under the action of the limiting spring, realizing the fixation of the door body and the frame without additional manual locking.
[0007] As an improvement, a through hole is provided at the upper end of the connecting block. The upper end of the limiting block is connected with a handle and the handle protrudes above the connecting block through the through hole; adopting this structure, the limiting block can be made to leave the limiting groove through the exposed handle, enabling the door body to be opened, making it more convenient to use.
[0008] As an improvement, grooves are provided on each connecting plate and on the end face facing the other connecting plate. The two ends of the door body are slidably connected in the two grooves; adopting this structure, the grooves can prevent the door body from separating from the connecting plate, improving the stability of the door body movement.
[0009] As an improvement, four fixed pulleys are rotatably connected to the top of the frame. Two of the fixed pulleys are arranged in the front and back corresponding to each other on the left part of the top of the frame, and the other two fixed pulleys are arranged in the front and back corresponding to each other on the right part of the top of the frame. The same steel wire rope is wound around every two fixed pulleys corresponding to each other in the front and back. One end of each steel wire rope is connected to the door body, and the other end of each steel wire rope is connected with a counterweight block. With this structure, setting two steel wire ropes to connect with the door body can prevent the door body from falling due to the breakage of one of the steel wire ropes, improving safety, and each steel wire rope corresponding to the front and back two fixed pulleys can prevent the steel wire rope from contacting the frame, ensuring the smooth movement of the door body up and down.
[0010] As an improvement, two left and right hanging rings for connecting with one end of the steel wire rope are threadedly connected to the top of the door body. With this structure, it has the advantages of simple structure and convenient connection.
[0011] As an improvement, a number of buffer springs evenly distributed at equal intervals in the left - right direction are connected to the bottom end of the stop bar. With this structure, it plays a buffering role when the door body moves upward to contact the stop bar. Description of the Drawings

Detailed Description of the Invention
[0017] The following will make a detailed description of a door body driving mechanism of a sheet hot - forming press of the present utility model with reference to the drawings.
[0018] As shown in Figures 1 to 4As shown in the figure, a driving mechanism for the door of a sheet hot forming press includes a frame 1, a door body 2, a counterweight 3, a fixed pulley 4, a fixing component 5, a steel wire rope 6, a stop bar 7, and two connecting plates 8. A receiving cavity 9 is provided inside the frame 1, and the receiving cavity 9 forms an opening at the front end of the frame 1. The two connecting plates 8 are both connected to the front end of the frame 1 and are respectively located on both sides of the opening. The left and right ends of the door body 2 are respectively slidably connected to the two connecting plates 8, and the sliding direction is the vertical direction. By moving the door body 2, the opening can be opened or closed. When the door body 2 moves upward, the opening is opened, and when it moves downward, the opening is closed. As Figure 3 shown, a groove 14 is provided on each connecting plate 8 on the end face facing the other connecting plate 8. The two ends of the door body 2 are slidably connected in the two grooves 14. And for the convenience of installing the door body 2, the grooves 14 in this embodiment penetrate through the upper end face of the connecting plate 8.
[0019] As Figure 4 shown, a fixed pulley 4 is rotatably connected to the top end of the frame 1. One end of the steel wire rope 6 is connected to the top end of the door body 2, and the other end of the steel wire rope 6 is wound around the fixed pulley 4 and then connected to the counterweight 3, so that the counterweight 3 is suspended at the rear side of the frame 1. The counterweight 3 makes the door body 2 move upward to open the opening. That is to say, the weight of the counterweight 3 is greater than the weight of the door body 2, and the weight of the counterweight 3 is selected according to the acceleration required when the door body 2 is opened. As Figure 1 and Figure 2 shown, the stop bar 7 is connected to the front end face of the frame 1 and is located on the moving path of the upward movement of the door body 2. That is to say, the stop bar 7 is located above the door body 2. In addition, a plurality of buffer springs 16 are evenly distributed at equal intervals in the left-right direction at the bottom end of the stop bar 7, and the buffer springs 16 play a buffering role.
[0020] As Figure 1 and Figure 2 shown, the fixing component 5 is connected to the lower part of the frame 1 and is used to fix the door body 2 to the frame 1 when the opening is closed. Specifically, the fixing component 5 fixes the lower part of the door body 2 to the frame 1. As Figure 4As shown in the figure, the fixing component 5 includes a connecting block 51, a limiting block 52 and a limiting spring 53. The connecting block 51 is connected to the lower part of the front end face of the frame 1. There is a gap between the connecting block 51 and the front end face of the frame 1 for the door body 2 to pass through. The limiting block 52 is slidably connected in the connecting block 51 in the front-rear direction. A limiting spring 53 is connected between the front end of the limiting block 52 and the connecting block 51. The limiting spring 53 makes the rear end of the limiting block 52 protrude outside the connecting block 51. There is an inclined surface 10 at the rear end of the limiting block 52. The inclined surface 10 is arranged from the lower left to the upper right. The inclined surface 10 is located on the moving path of the door body 2. There is a limiting groove 11 on the front end face of the door body 2 for the rear end of the limiting block 52 to be inserted into. When the door body 2 moves downward and the lower end of the door body 2 abuts against the inclined surface 10, the limiting block 52 moves forward. Specifically, when the opening is opened, the limiting spring 53 makes the rear end of the limiting block 52 protrude outside, that is, the inclined surface 10 is located on the moving path of the door body 2. Then the door body 2 moves downward and abuts against the inclined surface 10, causing the limiting block 52 to move forward. When the limiting groove 11 corresponds to the same height as the limiting block 52, the limiting spring 53 makes the limiting block 52 snap into the limiting groove 11. In addition, there is a through hole 12 at the upper end of the connecting block 51. The upper end of the limiting block 52 is connected with a handle 13, and the handle 13 protrudes above the connecting block 51 through the through hole 12.
[0021] As Figures 1 to 3 shown, four fixed pulleys 4 are rotatably connected to the top end of the frame 1. Two of the fixed pulleys 4 are arranged corresponding to each other in the front-rear direction at the left part of the top end of the frame 1, and the other two fixed pulleys 4 are arranged corresponding to each other in the front-rear direction at the right part of the top end of the frame 1. The same steel wire rope 6 is wound around every two front-rear corresponding fixed pulleys 4. One end of each steel wire rope 6 is connected to the door body 2, and the other end of each steel wire rope 6 is connected with a counterweight 3. Two left and right suspension rings 15 for connecting one end of the steel wire rope 6 are threadedly connected to the top end of the door body 2. That is to say, there are also two steel wire ropes 6. Each steel wire rope 6 corresponds to a counterweight 3, two fixed pulleys 4 and a suspension ring 15, and the blocking strip 7 is located between the two steel wire ropes 6.
[0022] In the utility model, due to the setting of the counterweight 3, the counterweight 3 makes the door body 2 move upward. Therefore, when the door body 2 is in the open state, the counterweight 3 will make the door body 2 have a tendency to move upward, and the blocking strip 7 blocks the door body 2 from continuing to move upward. At this time, the door body 2 can be kept in a force balance state, and there is no need to additionally set a high-position door lock to prevent the door body 2 from descending when the door body 2 is in the open state at a high position. That is, the worker no longer needs to toggle the high-position door lock to keep the door body 2 in the open state, making it more convenient to use. When the door body 2 is in the closed state, to prevent the door body 2 from moving upward under the action of the counterweight 3, the door body 2 is fixed at a low position by the fixing component 5 at a low position. When unlocking is required, the worker only needs to unlock the fixing component 5 at a low position, making the use of the press more convenient.
[0023] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above-mentioned one embodiment. All other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.
