Description

Technical Field

[0001] The present invention belongs to the technical field of automobile cutting die frames, and more specifically, relates to a lifting device for a new energy automobile cutting die frame. Background Art

[0002] Currently, stamping manufacturing is a very important processing and production method in the manufacturing industry. Since stamping casting molds are sometimes large in tonnage, when moving and lifting such heavy casting molds, it is generally necessary to use the steel wire rope of the overhead crane and the lifting lugs of the mold to lift them.

[0003] The existing patent authorization announcement number: CN207890892U, discloses a rear panel mold lifting device, which relates to the field of automotive mold technology. The device includes a first lifting lug and a second lifting lug arranged parallel to the mold body, and a lifting rod for use with the first and second lifting lugs. The first and second lifting lugs are coaxially provided with lifting rod sockets. The lifting rod is threadedly connected to a limit nut at one end near the second lifting lug, and a fixing nut is threadedly connected to the other end of the lifting rod. The lifting rod is provided with a tightening mechanism at the end near the fixing nut for driving the lifting rod to rotate and tighten the wire rope. The tightening mechanism drives the lifting rod to rotate, tightening the wire rope around the lifting rod, thereby tightening the wire ropes at the four corners of the mold body. When the overhead crane lifts the mold body, the mold body remains stable, the components on the mold body are not impacted, and the mold body is not easily damaged.

[0004] However, the operation in the prior art is not very convenient, and requires a nut to fix and a tightening mechanism to match the lifting rod, which is relatively cumbersome. Utility Model Content

The upper surface of the base plate 201 is connected, the fixed block 501 is connected to the lifting ear 502, and the lifting ear 502 is slidably connected to the latch column 503. When it is necessary to lift and move the cutting die frame body 20, the rope is connected to one end of the latch column 503 and then slidably connected to the lifting ear 502. Since the gravity of the cutting die frame body 20 is downward, the lifting traction force is upward and greater than the downward gravity of the cutting die frame body 20. At this time, the contact part between the latch column 503 and the lifting ear 502 is more tightly stressed, so that the latch column 503 will not swing left and right during the lifting process. When it is not necessary to lift and move, the latch column 503 is pulled out, and the cutting die frame body 20 rises steadily during lifting, which is not only convenient to operate but also saves costs.
