[0001] The invention relates to the technical field of stamping forming devices, and in particular to an aluminum alloy high-speed rail handle piece forming device. Background Art

[0002] Aluminum alloy high-speed rail handles play an important role inside high-speed rail carriages. They are not only convenient for passengers to open and close doors, but also serve to decorate carriages. The design, material, manufacturing process and installation method of aluminum alloy high-speed rail handles are unique. There are many types of handles on high-speed rails, such as common handles. In the past, when a round rod was stamped into a U-shaped handle, it was usually divided into two stampings or one stamping. The two-step stamping requires holding the round rod and stamping it 90 degrees once, and then stamping the other side. The efficiency is low, the stamping quality is average, and it is unsafe; while in the one-step stamping, when the round rod is formed into a U-shape, it is easy to get stuck on the stamping part, and it is not easy to complete the purpose of blanking.

[0011] Preferably, the two groups of extrusion assemblies are arranged in mirror symmetry, and the protruding portion on one side of the extrusion block is on the inner side of the forming groove.

[0012] Preferably, the rotating rod is fixedly connected to the rotating shaft of the motor, and the unloading tray partially passes through the interior of the movable opening.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Put the handle rod to be stamped into the discharge box. The handle rod will roll through the lower opening of the discharge box to the position of the discharge tray. The motor drives the rotating rod and the two sets of discharge trays to rotate, so that the handle rod enters the inner position of the material opening. The motor controls the rotation transmission and rolls one by one from the feed chute into the workpiece slot. After the processing is completed, it is discharged by cooperating with the push assembly and the discharge chute, automatically completing the purpose of loading and unloading one by one, and improving the safety of manual loading.

[0015] 2. When the handle rod rolls into the workpiece groove, the punching frame is pulled downward by using two sets of hydraulic cylinders and fixed sleeves, so that the punching frame enters the workpiece groove and the forming groove, and the handle rod is punched into a U-shaped state. When the punching frame enters the workpiece groove and the forming groove, the mounting sleeve and the push plate are driven to move downward, and when the lower side of the push plate contacts the fixed plate, it is pushed upward and retracted into the mounting sleeve and fixed together with the magnetic sheet by magnetic attraction. During this process, the punching frame will punch the handle rod into the forming groove. When moving to the bottom of the forming groove, the inclined part of the lower side of the push plate contacts the fixed plate, pushing the three sets of limit rods to move into the workpiece groove, and at the same time squeezing the three sets of return springs. The three sets of limit rods are limited to the upper side of the workpiece groove, and the fixed plate will move to the upper side of the convex strip. Therefore, when the punching frame rises upward to punch and form the handle rod, the punching frame will bring up the handle rods that have been punched and bent on both sides to avoid difficulty in directly pushing the material in the forming groove and the workpiece groove.

[0016] 3. The convex strip at one end of the push plate is restricted by the fixed plate, so that the magnetic sheet and the metal strip are separated, the installation sleeve is driven to move upward, and the three groups of limiting rods are restricted and supported by the push plate, and restricted in the workpiece slot. Therefore, when the stamping frame rises, the handle rod that is stuck on the outside of the stamping frame and is not easy to remove is brought to the workpiece slot and restricted from moving, so that the stamping frame and the handle rod stuck on the outside are slowly separated. When the handle rod is about to slide to the notch position, the installation sleeve will pull up the push plate, and the convex strip will pass over the upper side of the fixed plate. The three groups of limiting rods are pushed back by the reset spring to release the restriction on the handle rod. At this time, the handle rod is pulled out of the workpiece slot and partially stuck in the notch position, which promotes the push assembly to achieve the purpose of automatic unloading.

[0017] 4. When the handle rod just leaves the workpiece slot, the rack is driven by the stamping frame to mesh with the gear, driving the shaft rod, fixed rod, and push rod to rotate, tightening the torsion spring, and the two sets of push rods will quickly push the handle rod down the downward slide to prevent it from getting stuck on the stamping frame, making it difficult to complete the unloading work.

[0018] 5. During stamping, the handle rod will enter the extrusion port of the extrusion block, pushing the extrusion block to rotate counterclockwise in the circular groove, stretching the double hook spring at the same time, and the upper positions of the extrusion blocks on both sides rotate toward the middle direction, pushing the bend of the handle rod again to prevent the outward stress angle of the handle rod from not reaching the requirement of 90 degrees after being pulled out, and to prevent the stamping frame from being unable to effectively bring it out, thereby promoting the purpose of working with the pushing assembly.

When the handle bar 14 is pulled out of the workpiece groove 58, and is partially stuck in the notch 56, the push assembly 518 is promoted to achieve the purpose of automatic unloading; secondly, when the handle bar 14 just leaves the workpiece groove 58, the rack 5187 is driven by the stamping frame 55 to mesh with the gear 5183, driving the shaft 5182, the fixed rod 5184, and the push rod 5185 to rotate, tightening the torsion spring 5186, and the two sets of push rods 5185 will quickly push the handle bar 14 down the lower material slide 6 to prevent it from being stuck on the stamping frame 55 and making it difficult to complete the unloading work;In addition, during stamping, the handle bar 14 will enter the extrusion port 5193 of the extrusion block 5192, pushing the extrusion block 5192 to rotate counterclockwise in the circular groove 5191, while stretching the double hook spring 5196, and the upper side positions of the extrusion blocks 5192 on both sides rotate toward the middle direction, pushing the bend of the handle bar 14 again, avoiding the stress angle of the handle bar 14 not reaching the requirement of 90 degrees after being pulled out, and avoiding the punching frame 55 from being unable to effectively bring it out, promoting the purpose of working with the push assembly 518. ;
