Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold transfer arms, in particular to a mold transfer arm for rapid mold change. Background Art
[0002] The main equipment for stamping production is the punch press. At present, the tables of conventional small and medium-sized punch presses are basically unable to move, and the price of punch presses with movable tables is also very expensive. Generally, small and medium-sized enterprises use conventional punch presses as production equipment. The mold on the punch press needs to be manually pushed in and pulled out so that the mold can be smoothly loaded and unloaded. During the forced pushing and pulling process, the mold is prone to tipping over. In the mild case, the machine tool and mold are damaged, and in the severe case, personal injury is caused. Therefore, the mold transfer arm is used.
[0003] Currently, existing mold transfer arms are usually fixedly installed. However, such a fixed installation method restricts the mold transfer arms to the same position and cannot be adjusted according to the needs of lifting the workpiece, resulting in certain limitations during use. Utility Model Content
[0004] In order to solve the problem that the existing mold transfer arm cannot realize the adaptive adjustment function, the utility model provides a mold transfer arm with rapid mold change.
[0005] In view of the above problems, the technical solution proposed by the present invention is:
[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion. The swing arm is connected to the swing arm by a spring, and a spring is provided on the hook portion.
[0007] Furthermore, the mold transfer arm body includes an arm rod, a bracket is installed at the bottom end of the arm rod, and a connecting pin is inserted between the bracket and the arm rod.
[0008] The beneficial effect of adopting the above further solution is that, by inserting a pin shaft between the bracket and the arm rod, one end of the mold transfer arm body can form a lateral swing connection relationship with the connecting seat.
[0009] Furthermore, the inner rotation of the arm is connected to a supporting wheel and a stopper, and the top surfaces of the supporting wheel and the stopper extend to the top of the arm.
[0010] The beneficial effect of adopting the above further solution is that the support wheel rotates at the top of the arm, which facilitates the rolling conveyance of the workpiece at the top of the arm, and the unidirectional rotation of the stop block can block the workpiece from retreating, thereby preventing the workpiece from slipping.
[0011] Furthermore, the connecting seat includes a seat body, and one end of the pin shaft passes through one side of the seat body and is rotatably connected.
[0012] The beneficial effect of adopting the above further solution is that, through the insertion of the pin shaft, a tight hinged relationship is established between the seat body, the bracket and the arm.
[0013] Furthermore, a plurality of positioning holes are provided on the outer wall of the base.
[0014] The beneficial effect of adopting the above further solution is that, by setting the positioning hole, a position is provided for the insertion of the insertion shaft.
[0015] Furthermore, a fixing component is provided on one side of the interior of the bracket, and the fixing component includes a twist cap, one side of the twist cap is connected to a screw pile, and the screw pile is threadedly connected to one side of the bracket, one end of the screw pile passes through the bracket and is connected to an insert shaft, and one end of the insert shaft extends to the inside of one of the positioning holes.
[0016] The beneficial effect of adopting the above further solution is that the screw pile is rotated by the twist cap, so that one end of the insertion shaft can extend into the interior of the positioning hole, thereby facilitating the fixation of the mold transfer arm body that is swung to a specified angle.
[0017] Furthermore, a limit ring is sleeved on one side of the outer wall of the lead screw, and the limit ring is located between the two threads with opposite rotation directions.
[0018] The beneficial effect of adopting the above further solution is that, by using the limiting ring in combination, the two mold transfer arm bodies are prevented from being squeezed against each other.
[0019] Furthermore, the two sliders are both in the shape of an "I".
[0020] The beneficial effect of adopting the above further solution is that, through the “I”-shaped arrangement, the slider can maintain stable sliding inside the adjustment frame.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] This type of fast-changing mold-changing mold-transferring arm can be adjusted accordingly according to the needs of different workpieces through the mutual cooperation of the slider, the connecting seat and the pin shaft, so that the mold-transferring arm can adapt to the transportation of more workpieces. By turning the crank, it drives the screw to rotate forward and backward, and the setting of the opposite threads on both sides of the outer wall of the screw allows the two sliders to move away from or close to each other on the plate frame, and the connection between the connecting seat and the pin shaft allows the two mold-transferring arm bodies to move synchronously with the sliders until they adapt to the size of the workpiece to be transported. Secondly, through the interlaced connection of the pin shaft, the mold-transferring arm body can swing on one side of the connecting seat, thereby adjusting different transportation directions, so that the mold-transferring arm has a wider range of use.
