Description

Technical Field

[0001] This utility model relates to forging, stamping and other industrial fields, specifically a C-type mounting hanger for a press slide. Background Technology

[0002] The gantry double-point press is a press in which the crank acts on the slider at two points, and the slider is driven by two connecting rods. It adopts the integral steel plate welding of the gantry, which eliminates the disadvantages of the split body of the traditional closed press that requires assembly and debugging. It has the good precision, rigidity and strength performance of the closed press, as well as the simple installation and convenient operation of the open press.

[0003] Currently, when installing the slider of a gantry double-point press, due to the limitations of the integral machine body, the slider cannot be directly lifted by an overhead crane. Therefore, a forklift is usually used to lift and fork it in, and then the slider's connecting rod is connected to the crankshaft of the transmission. This method is acceptable for small-tonnage gantry double-point presses, but when dealing with large-tonnage gantry double-point presses, it results in a larger forklift tonnage required for slider installation. Moreover, even when using a large forklift, the slider installation is not stable enough, and it is more dangerous for workers to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a C-type mounting hanger for a press slide to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, a C-type mounting hanger for a press slide is provided, comprising a hanger, a connecting frame screwed to the bottom of the hanger, and a mounting frame screwed to the end of the connecting frame away from the hanger. A connecting rod cover is mounted on one side of the hanger, and a slide is disposed below the connecting rod cover. A slide is mounted on the top of the mounting frame via fasteners, including T-nuts, double-ended screws, and nuts. The slide is fixed to the mounting frame by eight T-nuts, double-ended screws, and nuts. A lifting rope is mounted on the top of the hanger.

[0006] Preferably, the hanger, connecting frame, and mounting frame are connected by high-strength bolts and nuts, and the hanger, connecting frame, and mounting frame are detachable.

[0007] Preferably, the hanger, connecting frame, and mounting frame are combined in a "C" shape, and both the hanger and mounting frame are "L" shaped; the length of the hanger is greater than the length of the mounting frame.

[0008] Preferably, a workbench is mounted below the mounting bracket via a fastener, and the workbench has a rectangular cross-section.

[0009] Preferably, the T-nut has a positioning groove inside, and the positioning groove is adapted to the size of the positioning seat. The positioning seat is inserted into the positioning groove and fixed by fixing bolts. Both the positioning groove and the positioning seat have rectangular cross sections.

[0010] Preferably, the positioning seat has a screw hole, and the T-nut has a through hole on its side wall. The fixing bolt passes through the through hole and is screwed into the screw hole. A double-ended screw is welded and fixed to the bottom of the positioning seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The lifting fixture of this utility model consists of a lifting frame, a connecting frame, and a mounting frame. When the tonnage is large and the machine body is tall, the lifting frame, connecting frame, and mounting frame are used together. When encountering a small gantry double-point press, the connecting frame in the middle can be removed, and only the lifting frame and mounting frame are combined, which can reduce the height of the lifting fixture. Therefore, this C-type lifting fixture can be adapted to gantry double-point presses of various tonnages. It does not require the use of a large-tonnage forklift to assist in assembly, which can reduce the risk of injury to assembly personnel. The segmented structure can reduce the overhead crane height requirements in the workshop. Attached Figure Description
