Description

Technical Field

[0001] This utility model relates to the field of spring seat technology, specifically to a spring seat for a jaw device of a cold-rolled strip steel coiler. Background Technology

[0002] A coiler with a clamping function is a key piece of equipment in a cold rolling production line. The function of the clamping jaw is to clamp the head of the strip steel and complete the winding of the steel coil. However, the spring seat of the traditional clamping jaw needs to be embedded inside the main shaft. As a result, the main shaft needs to be made into a split structure. The support roller needs to be installed at the end of the main shaft with the help of a connecting shaft. Moreover, the end of the spring seat protrudes too far, which greatly reduces the structural strength of the spring seat.

[0003] Compared to existing spring seats, the following drawbacks still exist: Figure 1 As shown, its structure is complex and has many potential failure points. The spring seat is embedded inside the main shaft, and the support roller and connecting shaft need to be installed at the end of the main shaft via a transition flange. The split structure of the main shaft makes the connecting bolts easy to break. At the same time, the spring seat has low structural strength. Because the spring seat is at a high stress point, it is subjected to a large bending moment and is prone to breakage at the root of the spring seat. Utility Model Content

[0004] The purpose of this utility model is to provide a spring seat for the jaw device of a cold-rolled strip steel coiler, which solves the following technical problems: its structure is complex and has many failure points. The spring seat is embedded inside the main shaft, and the support roller and connecting shaft need to be installed at the end of the main shaft through a transition flange. The split structure of the main shaft makes the connecting bolts easy to break. At the same time, the spring seat has low structural strength. Because the stress point of the spring seat is high, the bending moment is large, and it is easy to break at the root of the spring seat.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A spring seat for a jaw device of a cold-rolled strip steel coiler includes: a second spindle housing; a pyramidal sleeve is provided on the inner side of the second spindle housing, a second spindle body is provided on the inner side of the pyramidal sleeve, a second spring seat is provided on the outer side of the second spindle body, and a second spring element is connected to the left end of the second spring seat.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 2 As shown, this utility model is a spring seat for a jaw device of a cold-rolled strip steel coiler. Specifically, it has a simple structure, high strength, convenient installation and low failure rate. It includes a second spindle housing 8; a pyramidal sleeve 15 is provided on the inner side of the second spindle housing 8, a second spindle body 10 is provided on the inner side of the pyramidal sleeve 15, a second spring seat 11 is provided on the outer side of the second spindle body 10, and a second spring member 12 is connected to the left end of the second spring seat 11.

[0023] In this embodiment, preferably, the right end of the second main shaft 10 is connected to the rear end 9 of the main shaft for docking and installation with the machine, which enables the spring seat to be stably docked and installed with the cold-rolled strip steel coiler.

[0024] In this embodiment, preferably, the second spindle body 10 is movably installed inside the pyramidal sleeve 15. The pyramidal sleeve 15 is threadedly connected to the second spindle housing 8 by the second bolt 14, which enables a stable connection and installation between the second spindle housing 8 and the second spindle body 10, and facilitates the disassembly and replacement of the second spindle body 10 as a whole in the later stage.

[0025] In this embodiment, preferably, the second spring seat 11 is fixedly installed on the outer side of the middle part of the second main shaft 10 and located inside the pyramid sleeve 15. The outer side of the pyramid sleeve 15 is provided with multiple sets of reinforcing ribs, which can make the second main shaft 10 more stable during elastic telescopic movement.

[0026] In this embodiment, preferably, the second spring seat 11 is elastically extended and retracted within the second spindle housing 8 by the second spring member 12 provided at the left end, and the second spring seat 11 is fixedly connected to the second spindle body 10 and passes through the inner side of the left end of the pyramid sleeve 15.

[0027] In this embodiment, preferably, the diameter of the right longitudinal section of the second main shaft 10 is larger than the diameter of the left longitudinal section, so as to be connected to the second shaft end cover 13 by bolts.

[0028] In this embodiment, preferably, the second main shaft 10 is nested and fixedly connected to the second shaft end cover 13 and the pyramidal sleeve 15 respectively, so that after the second main shaft 10 and the second shaft end cover 13 are fixedly connected by bolts, it is convenient to connect to the jaws of the cold-rolled strip coiler.

[0029] In summary, in comparison Figure 1 In the first spindle body 2, the first spring element 4 is located on the inner side of the left end of the connecting shaft block 6 and is connected to the first shaft end cover 5. The connecting shaft block 6 is connected to the first spindle housing 1 by the first bolt 7 using a threaded connection. When the first spindle body 2 moves to the left, it will extend and retract under the action of the first spring element 4, thereby providing tail support through the first spring seat 3. However, the connection between the first spindle housing 1 and the first shaft end cover 5 is connected to each other through the connecting shaft block 6. The first spring seat 3 is embedded inside the first spindle body 2. The first spindle housing 1 and the connecting shaft block 6 need to be installed at the end of the first spindle body 2 through the transition flange. The split structure of the first spindle body 2 makes the first bolt 7 easy to break. At this time, because the first spring seat 3 has a high stress point, the bending moment is large, and it is easy to break at the root of the first spring seat 3.

[0030] After improvement, the second spring seat 11 is designed with a flat structure, which greatly shortens the height of the second spring seat 11, significantly reduces the bending moment, and greatly enhances the structural strength of the second spring seat 11. When the second spring member 12 is inserted into the second spring seat 11 and installed on the pyramidal sleeve 15, the two second spring members 12 are pressed inside the second spring seat 11. The opening and closing of the jaws is achieved by the pyramidal sleeve 15 driving the jaws. Figure 2 In this design, the second main shaft 10 is a single integral shaft, eliminating the connecting flange and connecting shaft block 6. The support roller is not installed using the connecting shaft block 6, which increases the overall strength of the second main shaft 10.

[0031] Example 2

[0032] This embodiment is obtained by combining Embodiment 1 and Embodiment 2.

[0033] By eliminating the connecting shaft block 6 as the connecting component between the first spindle housing 1 and the first shaft end cover 5, the pyramidal sleeve 15 is fixedly installed inside the second spindle housing 8. After the second spring seat 11 is fixedly connected to the second spindle body 10 and passes through the pyramidal sleeve 15, it drives the second spring 12 to elastically expand and contract within the second spindle housing 8, enabling the second spindle body 10 to reciprocate and achieve elastic force.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
