Description

Technical Field

[0001] This utility model relates to the field of hydraulic forming machines, and in particular to a dual-station hydraulic forming machine. Background Technology

[0002] Currently, in modern industrial production, hydraulic forming machines are widely used as important processing equipment in the forming and processing of materials such as metals and plastics, playing a key role in many industries such as automobile manufacturing, aerospace, and electronics. For example, Chinese Patent Publication No. CN103625001A discloses a hydraulic forming machine structure. This hydraulic forming machine has a machine base, with a first hydraulic power unit located above the machine base. One end of the push rod of the first hydraulic power unit is connected to a sliding block. A second hydraulic power unit is located inside the sliding block, with one end of the push rod of the second hydraulic power unit connected to a push block. A push part is located below the push block. A plurality of fixing holes are provided around the periphery of the sliding block for locking the male mold portion. A bed is located below the machine base for supporting the female mold portion.

[0003] However, traditional hydraulic forming machines have gradually revealed some problems that urgently need to be solved in practical applications. Most traditional hydraulic forming machines only have a single forming function, that is, they can only perform the pressing and forming operation of workpieces. But in actual production processes, many workpieces often require other processing steps such as drilling after forming. This leads to the need for companies to configure additional drilling equipment, and workpieces need to be transferred and clamped multiple times between the forming machine and the drilling equipment. This not only increases the complexity of the production process, extends the production cycle, and reduces overall production efficiency, but also increases equipment purchase costs and space occupation. This drawback is particularly obvious for some small-scale production companies or those with high production efficiency requirements. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a dual-station hydraulic forming machine, which solves the technical problem that existing hydraulic forming machines cannot achieve simultaneous and stable forming and punching.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dual-station hydraulic forming machine, comprising a frame and a lifting seat that moves up and down along the frame, a hydraulic drive device for driving the lifting seat to move up and down, and a forming mold base located below the lifting seat. The forming mold base is used to place the mold for forming. A sliding seat is provided on the lower end face of the lifting seat, and a sliding drive device for driving the sliding seat to slide is provided on the lifting seat. A first station and a second station are arranged side by side on the lower end face of the sliding seat. A forming pressure block is provided on the first station, and a punching mechanism is detachably provided on the second station.

[0006] Furthermore, the drilling mechanism includes a mounting plate that is installed in conjunction with the sliding seat, a drilling post that is snapped into the lower end of the mounting plate, a guide plate that is sleeved on the drilling post, a plurality of guide posts on the guide plate, a guide sleeve on the lower end of the mounting plate, and a stabilizing spring. The guide sleeve cooperates with the guide post to achieve guidance, and the stabilizing spring is sleeved on the guide post and connects the guide plate and the guide sleeve.

[0007] Furthermore, a limiting protrusion is provided on the upper end of the guide post to limit the downward travel of the guide post.

[0008] Furthermore, a buffer block is provided on the upper surface of the limiting protrusion, and the buffer block is made of high-temperature resistant rubber.

[0009] Furthermore, a recess is provided on the upper surface of the high-temperature resistant rubber, and a pressure sensor is provided in the recess, with the upper surface of the pressure sensor protruding from the recess.

[0010] Furthermore, the lower end of the mounting plate is provided with a snap-fit ​​groove, and the upper end of the punching post is provided with a snap-fit ​​protrusion. The snap-fit ​​groove and the snap-fit ​​protrusion cooperate to achieve the snap-fit ​​between the punching post and the mounting plate.

[0011] Furthermore, the guide plate is provided with a clearance hole for avoiding the punching post. The diameter of the clearance hole is larger than the diameter of the punching post, so that the punching post can slide stably within the clearance hole.

[0012] Furthermore, the sliding drive device is a hydraulic cylinder, the bottom of which is hinged to the frame, and the piston rod of which is hinged to the sliding seat.

[0013] Furthermore, a lubricating layer is provided inside the guide sleeve. The lubricating layer is made of polytetrafluoroethylene and is used to reduce the friction between the guide sleeve and the guide post, thereby improving the smoothness of the drilling mechanism's movement.

[0014] Furthermore, a storage recess is provided in the middle of the lubricating layer, and lubricating grease is disposed in the storage recess.
