Description

Technical Field

[0001] The utility model relates to the technical field of workpiece storage of bending machines, in particular to a multi-layer semi-automatic heavy-duty mold library dedicated to bending machines. Background Art

[0002] During the use of the bending machine, depending on the type of workpiece being bent and the tonnage of the bending machine, many different types and lengths of upper and lower molds are required. At this time, a rack library that is convenient for storing a sufficient number of molds is needed. However, most mold libraries on the market are used to store small molds and only have the function of storing molds, and cannot assist in manual mold changing. With the demand for development, heavy-duty bending machines are widely used, and the corresponding molds are getting bigger and heavier. Manual handling and mold changing is time-consuming and labor-intensive, and there is also a great risk. The use of an automated mold library for automatic mold changing has a complex structure, low versatility, and a relatively high cost. Utility Model Content

[0003] The technical problems to be solved by the utility model are as follows: the traditional bending machine mold library only has the function of storing molds and cannot meet the needs of manually assisted mold changing; the traditional bending machine mold library cannot store heavy molds; manual mold changing has limitations and can only replace relatively light molds. Replacing heavy molds often requires the cooperation of multiple people and the cooperation of related lifting and handling tools, which is not only time-consuming and labor-intensive, but also poses a safety hazard of mold falling.

[0004] The utility model solves the technical problem by adopting the following technical solution: a multi-layer semi-automatic heavy-duty mold library for a bending machine, including a mold library part, a lower mold auxiliary replacement component and an upper mold auxiliary replacement component, wherein the mold library part includes a mold library frame, a lower mold storage partition, a lower mold support card plate, a lower mold limit baffle, an upper mold support plate, an upper mold hanging shaft, an upper mold hanging plate, a moving track of an upper mold auxiliary replacement component and a moving track of a lower mold auxiliary replacement component;

[0005] The lower mold auxiliary replacement assembly includes a lower mold auxiliary replacement assembly frame, a lifting screw, a linear guide rod, a transmission belt, a motor end pulley, a lower mold lifting reduction motor, a lower mold auxiliary replacement assembly moving roller and a lower mold moving platform;

[0006] The upper mold auxiliary replacement component includes an upper mold auxiliary replacement component frame, an upper mold replacement hanging plate, a mold limit block, an upper mold limit block mounting seat, a limit operating handle and a side handle.

[0007] The lower mold supporting card plate is locked inside the mold library frame by screws, and rectangular card slots for installing the lower mold storage partition are distributed on it. The lower mold limiting baffle is fixedly connected to the upper end of the lower mold storage partition.

[0008] The upper mold support plate is fixed to both sides of the mold library frame by screws, and four circular holes are opened on the upper mold support plate. The upper mold hanging shaft is passed through the circular holes and connected to the upper mold support plate. The upper mold hanging plate is hung on the upper mold hanging shaft through the circular holes on itself and connected to the upper mold hanging shaft. The upper mold auxiliary replacement component moving track is locked to the upper end of the mold library frame by screws, and the lower mold auxiliary replacement component moving track is locked to the side wall of the mold library frame by screws.

[0009] The lower mold auxiliary replacement component frame is installed on the lower mold auxiliary replacement component moving track through a slider, the lifting screw and the linear guide rod are installed on the lower mold auxiliary replacement component frame through the screw fixing plates on both sides, the lower mold lifting reduction motor is fixedly installed on the lower mold auxiliary replacement component frame, the motor end pulley is fixed on the output shaft of the lower mold lifting reduction motor, the outer side of the motor end pulley is sleeved with a transmission belt, and the lower mold auxiliary replacement component moving roller is fixed on the bottom of the lower mold auxiliary replacement component frame.

[0010] The upper mold auxiliary replacement component frame is installed on the upper mold auxiliary replacement component moving track through a slider, and the upper mold replacement hanging plate is fixed to the upper mold auxiliary replacement component frame through screws.

[0011] A foot adjusting screw pad is fixed at the bottom of the mold library frame through a foot adjusting screw.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model has a multi-layer semi-automatic heavy-duty mold library for bending machines with a simple structure and a building block-like quick-install structure, which is low in cost and easy to disassemble and maintain;

[0014] (2) The lower mold platform is raised and lowered by a motor to select molds between different layers. The mold can be manually pulled out by simply adjusting the alignment of the desired mold, saving time and effort;

[0015] (3) After selecting the required mold, you only need to adjust the position of the lower mold platform and align it with the working table of the bending machine, and then you can push the mold directly onto the working table of the bending machine. The operation is convenient and can be completed by one person, saving time and cost;

[0016] (4) The operation of the upper mold is roughly the same as that of the lower mold. Since the upper mold has only one layer and does not need to adjust the height, you only need to manually align the upper mold auxiliary replacement assembly with the upper beam of the bending machine to directly push the upper mold into the upper mold fixing seat of the bending machine, which is convenient to operate;

[0017] (5) This mold library has a simple structure and strong versatility. It does not require a complex control system and can be used with different bending machines, which is economical and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
