The slag bag can improve the exhaust efficiency during wheel hub casting, better improve the drainage effect in the cavity, and make the die-casting product have better quality. After the wheel hub is cast, the slag bag is located on the circumferential outer side of the wheel hub and is interconnected with the wheel hub rim; the slag bag connected to the wheel hub is usually removed by manual knocking, but manual knocking requires multiple manual knocking when removing the slag bag, which is inefficient and labor-intensive. Utility Model Content

[0003] The utility model aims to provide a high pressure casting wheel hub slag bag cutting and pressing machine which can cut off the slag bag of the high pressure casting wheel hub at one time.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-pressure casting wheel hub slag bag cutting and pressing machine, including a wheel hub positioning seat for positioning the wheel hub, a cutting and pressing assembly is provided above the wheel hub positioning seat, the cutting and pressing assembly includes a cutter disc coaxially arranged with the positioning seat, a plurality of blades are fixed to the lower end of the cutter disc, the plurality of blades extend downward and are evenly spaced in a ring with the center of the cutter disc as the center of the circle, the upper end of the cutter disc is connected to a downward pressure driver, and the downward pressure driver drives the cutter disc to perform lifting and lowering movements.

[0005] In actual operation, the operator first places the wheel hub on the wheel hub positioning seat, and the wheel hub positioning seat positions the wheel hub. Then the operator starts the downward drive to lower the cutter disc, so that the blade cuts off the slag bag of the wheel hub at one time.

[0006] The hub positioning seat is any existing positioning seat that can position the hub workpiece and limit the radial position of the hub workpiece. The downward pressure driver can be a cylinder, a hydraulic cylinder, etc.

[0007] This solution positions the wheel hub through the wheel hub positioning seat, and drives the cutter disc downward through the downward pressure driver, so that the blade can cut off the slag bag around the wheel hub, thereby completing the work of removing the slag bag in one go. It does not need to be knocked out manually, is more efficient and reduces labor intensity.

[0008] Preferably, the cutter disc is provided with a plurality of outwardly extending fixed groove groups, the fixed groove groups are evenly spaced in a circular ring shape with the center of the cutter disc as the center, and each group of the fixed groove groups includes at least two outwardly extending and parallel fixed grooves; each blade corresponds to a fixed groove group, and the fixed groove is equipped with a locking piece, and the locking piece passes through the fixed groove and cooperates with the upper end thread of the blade to realize the adjustable inner and outer positions of the blade on the cutter disc.

[0009] When adjusting the inner and outer positions of the blade, loosen the locking piece, move the blade, move the blade to a suitable position, and then tighten the locking piece; adjusting the position of the blade can be used to cut and press slag bags on hub workpieces of different diameters, making the device more versatile.

[0015] The radial positioning of the wheel hub is achieved by cooperating with the brake drum through the annular positioning groove.

[0016] Preferably, the downward drive is fixed on the upper end of the workbench, and the workbench is provided with a stroke detection sensor and a lifting rod cooperating with the stroke detection sensor, the lifting rod is fixedly connected to the lifting plate, and the stroke detection sensor detects the lifting stroke of the lifting plate through the lifting rod.

[0017] The lifting rod is fixedly connected to the lifting plate, and the travel detection sensor detects the up and down movement of the lifting rod to detect the lifting limit position of the lifting plate. When the lifting plate rises or falls to the limit position, the travel detection sensor will send an instruction to the downward pressure driver to control the downward pressure driver to stop driving the lifting plate to rise or fall. The lifting rod is provided with a trigger end that cooperates with the travel detection sensor. The travel detection sensor is electrically connected to the downward pressure driver.

[0018] Preferably, the wheel hub positioning seat is fixed to the lower end of the workbench, and the workbench is provided with a collecting hopper below the wheel hub positioning seat.

[0020] Preferably, the upper end of the workbench is provided with a through groove running through from top to bottom, the upper end of the lifting plate is provided with a locking block extending upward and slidingly cooperating with the through groove, the locking block is provided with a locking hole with a side opening, and the workbench is provided with a movable block that can extend into the locking hole or away from the locking hole.

[0021] When the slag bag does not need to be cut and pressed, the lifting plate is located at the upper end of the entire workbench. At this time, the movable block extends into the lock hole to limit the descent of the lifting plate. When the slag bag needs to be cut and pressed, the movable block withdraws from the lock hole, allowing the lifting plate to descend; thereby improving the safety of the entire device.

[0022] The utility model has the advantage that the slag bag of the high-pressure cast wheel hub can be removed at one time, thereby reducing the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS
