Technical Field

[0001] The utility model relates to the technical field of presses, in particular to an automatic press with a guiding and positioning function. Background Art

[0002] The press is the main equipment for compression molding. It is divided into frame structure and column structure according to the frame structure. According to the position of the main pressure cylinder, the press is divided into upper pressure type and lower pressure type. The lower pressure press with the cylinder at the bottom can be used to press large plastic laminates, and the upper pressure press is often used to press general plastic parts. According to the type of working fluid, it can also be divided into oil press driven by hydraulic oil and water press driven by oil-water emulsion. The power source generally uses a central energy storage station. A central energy storage station can drive dozens to hundreds of hydraulic presses at the same time, which is more advantageous when the factory's production scale is large. In addition, the laboratory also has various forms of manual presses such as screw presses, jack presses, etc.

[0004] With respect to the above utility model, we found that the utility model directly maintains pressure when in use, and once the material is offset or moved by force during the downward pressing process, the pressure-maintaining effect will be affected, thereby reducing the pressure-maintaining accuracy of the pressure-maintaining machine. Utility Model Content

[0005] The utility model provides an automatic press with a guiding and positioning function to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An automatic press with a guiding and positioning function, comprising a press frame, a bottom feeding mechanism installed at the bottom of the press frame, a driving motor fixedly installed at the top of the press frame, a rotating frame rotating at the top of the press frame, a side plate installed at the back of the press frame, and further comprising:

[0011] An auxiliary pressure rod is installed on one side of the punching mechanism and the bottom feeding mechanism, and is used to assist the bottom feeding mechanism in performing up and down transmission.

[0012] The rotating frame is driven to rotate by the driving motor, thereby driving the stamping mechanism to perform stamping operations.

[0013] Furthermore, a stamping platform is provided on the press frame at the bottom of the stamping mechanism, a feeding port cooperating with the bottom feeding mechanism is opened on the stamping platform, and a feeding slide is welded and installed on the front of the stamping platform.

[0014] The setting of the feeding port facilitates the cooperation between the stamping mechanism and the bottom feeding mechanism to lift and lower the product.

[0015] Furthermore, a main gear is rotatably mounted on one side of the driving motor through a driving gear, one end of the main gear penetrates through the press frame and is fixedly connected to the rotating frame, and an auxiliary gear is engaged and mounted on one side of the main gear.

[0016] The transmission effect of different components is achieved by assisting the rotation through multiple sets of gears.

[0017] Furthermore, the stamping mechanism includes an eccentric wheel fixedly mounted on the rotating frame, a transmission block installed in a circle outside the eccentric wheel, a pressing part installed at the bottom of the transmission block and welded by two sets of connecting chains, a sliding frame welded at the bottom of the pressing part, a connecting part welded at the bottom of the sliding frame, and a ejector pin installed at the bottom of the connecting part.

[0018] When the eccentric wheel rotates, its axis and the rotation axis are not at the same central position, so the position is inconsistent when it rotates. The transmission block installed in a circle outside the eccentric wheel floats up and down through the rotation of the eccentric wheel, so that the ejector pin installed at the bottom is transmitted up and down, thereby realizing the function of automatic stamping.

[0019] Furthermore, the guide mechanism includes a guide limit block welded on the outside of the connecting portion, and an auxiliary block welded and installed on the top of the stamping platform, and a limited position surface is provided inside the auxiliary block.

[0020] When the ejector is pressed downward, the guide limit block and the limit surface are first engaged and limited, thereby achieving a guiding effect on the ejector and ensuring the accuracy of the ejector punching position.

[0021] Furthermore, guide rails are welded on both sides of the inner wall of the press frame, and both sides of the sliding frame slide in cooperation with the guide rails.

[0022] The guiding effect of the auxiliary guiding mechanism is achieved by sliding the two sides of the sliding frame in cooperation with the guide rails.

[0023] Furthermore, a pushing block is connected and installed at the end of the electric telescopic rod, and a pushing plate is installed on the front side of the pushing block.

[0024] The push block and the push plate are pushed back and forth by the electric telescopic rod, and at the same time, the connection part is pressed down to close the stamping platform, thereby blocking the push plate from pushing, so that the automatic press can achieve the effect of automatic pushing and unloading of materials.

[0025] Furthermore, a matching block is welded and installed on the top of the auxiliary pressure rod, a special-shaped block that cooperates with the matching block is fixedly installed on the rotating frame, the bottom of the auxiliary pressure rod passes through the press frame and is connected to an extrusion rod, the extrusion rod and the bottom of the bottom feeding mechanism are connected and installed through a flip frame, the flip frame and the extrusion rod are fixedly installed through a flip block, a rotating shaft is installed on the flip frame, both ends of the rotating shaft are rotatably installed with the press frame through bearings, and a return spring is fixedly installed between the bottom of the extrusion rod and the press frame.

[0026] By rotating the special-shaped block 71, it is reset by the reset spring 77, so that the auxiliary pressure rod 7 moves up and down. At the same time, the bottom of the auxiliary pressure rod 7 presses the extrusion rod 74, so that the extrusion rod 74 is pressed down, and the flip block 76 is pressed down by force, so that one side of the flip frame 73 installed on the press frame 1 is pressed down and flipped, thereby moving the bottom feeding mechanism 4 upward. As the special-shaped block 71 rotates, the bottom feeding mechanism 4 is transmitted up and down.

[0027] Beneficial effects of the utility model:

[0028] 1. During the use of the automatic press machine with a guiding and positioning function, when the ejector is pressed down, the guide limit block and the limit surface are first engaged and limited to achieve the guiding effect on the ejector, while ensuring the accuracy of the punching position of the ejector. At the same time, the guide rails welded on both sides of the inner wall of the auxiliary press frame make the two sides of the sliding frame slide in coordination with the guide rails, thereby achieving the guiding effect of the auxiliary guide mechanism with an auxiliary limiting function.

[0029] 2. This automatic press with a guiding and positioning function rotates the special-shaped block to move the auxiliary pressure rod up and down. At the same time, the bottom of the auxiliary pressure rod presses the extrusion rod to flip the flip frame, thereby moving the bottom feeding mechanism up. As the special-shaped block rotates, the bottom feeding mechanism is transmitted up and down. The main gear is driven by the driving motor to rotate the auxiliary gear, so that the push block and the push plate are pushed back and forth. At the same time, the connection part presses down to make the stamping platform stamped and closed, thereby blocking the push of the push plate, so that the automatic press can achieve the effect of automatic pushing and unloading, and realize the full automatic operation effect of the press.
