Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for installing static labyrinth oil seals of rolling mills, in particular to an installation device for static labyrinth oil seals of short stress rolling mills. Background Art

[0002] A short-stress rolling mill is a highly efficient machine used for rolling metal sheets or bars. It offers high-precision rolling and low stress concentration during operation. To ensure proper operation and extend the service life of the mill, key components must be effectively sealed to prevent lubricant leakage and the ingress of foreign matter.

[0003] When replacing the static labyrinth oil seal in a short stress rolling mill, the existing technology usually uses a hand hammer to hit the chisel for installation due to the small fitting clearance; however, this installation method has the following problems: the force-bearing area of the chisel head is small, and the new oil seal is easily damaged or chipped, resulting in damage to the oil seal and rework.

[0004] Therefore, there is an urgent need to design a short stress rolling mill static labyrinth oil seal installation device to solve the problems of small force area, easy damage during oil seal installation, and low efficiency caused by rework. Utility Model Content

[0007] Specifically, the knocking head is cylindrical, and a connecting rod is welded to the bottom of the knocking head.

[0008] Specifically, the connecting rod is connected to the knocking head, and the bottom end of the connecting rod is an inverted cone with a chamfer.

[0009] Specifically, the left oblique brace is provided on the left portion of the knocking head and the connecting rod, and the left oblique brace is used for supporting and applying force to the left portion of the pressure plate.

[0010] Specifically, the right diagonal brace is provided on the right part of the knocking head and the connecting rod, and the right diagonal brace is used for supporting and applying force to the right part of the pressing plate.

[0011] Specifically, the pressing plate is semicircular, and the inner side of the pressing plate presses against the boss of the static labyrinth oil seal of the rolling mill, so that the pressing plate makes the force-bearing area of the static labyrinth oil seal of the rolling mill uniform.

[0012] The utility model has the following beneficial effects:

[0013] The utility model designs a short stress rolling mill static labyrinth oil seal installation device: 1. A special installation tool is designed to increase the force-bearing area during oil seal installation, making the force more uniform.

[0014] 2. Reduce the probability of oil seal damage.

[0015] 3. Improved work efficiency and reduced repetitive work. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a structural diagram of the static labyrinth oil seal installation device for a short stress rolling mill.

[0017] In the figure: 1-knocking head, 1.1-connecting rod; 2-left diagonal brace, 2.1-right diagonal brace; 3-pressure plate; 4-static labyrinth oil seal. DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Example 1:

[0020] like Figure 1 As shown, a short stress rolling mill static labyrinth oil seal installation device includes a knocking head 1, a diagonal brace and a pressure plate 3. A connecting rod 1.1 is provided under the knocking head 1. The diagonal brace includes a left diagonal brace 2 and a right diagonal brace 2.1. The diagonal braces are provided on both sides of the connecting rod 1.1. The diagonal brace and the connecting rod 1.1 are connected to the pressure plate 3 below.

[0021] The knocking head 1 of the device is set to be cylindrical, and the cylindrical shape makes the force-bearing area larger. The knocking head 1 is used for knocking with a hammer when in use, and the connecting rod 1.1 is held to hammer the knocking head 1. The connecting rod 1.1 is welded to the bottom of the knocking head 1, and the connecting rod 1.1 is used to connect the knocking head 1. The bottom end of the connecting rod 1.1 is set to an inverted cone with a chamfer, which increases the force-bearing area and the chamfer prevents the connecting rod 1.1 from damaging the static labyrinth oil seal. A left oblique support 2 and a right oblique support 2.1 are provided on both sides of the connecting rod 1.1. The left oblique support 2 and the right oblique support 2.1 are used to support the knocking head 1 and the connecting rod 1.1. At the same time, the lower parts of the left oblique support 2 and the right oblique support 2.1 are connected to the pressing plate 3, which also makes the force on the pressing plate 3 more uniform. The pressing plate 3 is semicircular, and the semicircular pressing plate 3 makes the force-bearing area larger, more uniform, and more suitable for installing a static labyrinth oil seal.
