Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical rolling, and relates to an auxiliary device for installing and supporting a copper wedge. Background Technique

[0002] In the metallurgical industry, a decoiler is a very common mechanical device. Its main function is to open the coil and draw out the leading end of the strip so that it enters the subsequent machine, thereby realizing the efficient and continuous processing of the coil. As the core component of the decoiler, the reel is mainly used to support the steel coil and bear the load. It mainly consists of a main shaft, a wedge, a tie rod, a segment plate, a telescopic cylinder, a crosshead baffle, etc. As a key part among them, by using the principle of the inclined plane, when the wedge receives the thrust and pull of the telescopic cylinder, the wedge axially moves through a specific angle, thereby realizing the outward or inward movement of the segment plate, and thus fixing the coil. Therefore, as a key part, the assembly of the wedge has a great influence on the accuracy of the equipment. In actual assembly, due to the tight fit between the top of the crosshead baffle and the wedge, it is necessary to install the crosshead and the wedge assembly together into the main shaft after the assembly is completed. However, after the crosshead and the wedge assembly are completed, due to the large self-weight and long length of the wedge, and at the same time, one side is supported by the crosshead baffle and the other side is suspended, it is difficult for the wedge to enter and align with the groove on the main shaft, resulting in great installation difficulty. Considering the above reasons, in order to improve work efficiency while ensuring accuracy, this device is specifically designed. Content of the Utility Model

[0003] The purpose of the utility model is to provide an auxiliary device for installing and supporting a copper wedge, which solves the problem that when installing the wedge of the decoiler, the wedge connected to the cross plate is difficult to enter and align with the groove on the main shaft due to its large self-weight and long length, and at the same time, one side is supported by the crosshead baffle and the other side is suspended, resulting in great installation difficulty.

[0004] The technical solution adopted by the utility model is an auxiliary device for installing and supporting a copper wedge, which includes a horizontal support rod. A fixed threaded hole is opened at the center of the horizontal support rod, adjustment holes are symmetrically opened on both sides of the fixed threaded hole, bolt assemblies are arranged in the adjustment holes, a vertical support rod is arranged in the fixed threaded hole, an adjustment threaded hole is opened at one end of the vertical support rod, and an adjustment bolt is arranged in the adjustment threaded hole.

[0005] The characteristics of the utility model also lie in that:

[0006] The cross-section of the horizontal support rod is square, and the parallelism error of the two planes connected to the adjustment holes on the horizontal support rod is less than 0.05 mm.

[0007] The fixed threaded hole is a fine-threaded thread.

[0008] The adjustment hole is an elongated hole, the extending direction of the elongated hole is the same as the direction of the horizontal support rod, and the adjustment hole is a counterbore.

[0009] The bolt assembly includes a bolt and a nut, where the nut is located in a counterbore, and the width of the counterbore is between the width of the nut and the diagonal length of the nut.

[0010] The threads on the vertical support rod extend from the opposite end of the self-adjusting threaded hole towards the adjusting threaded hole. The surface roughness of the opposite end of the vertical support rod relative to the adjusting threaded hole is Ra0.4 - 1.6, and the adjusting threaded hole uses fine pitch threads.

[0011] The surface roughness of the top of the adjusting bolt is Ra0.4 - 1.6.

[0012] The parallelism error at both ends of the assembly of the vertical support rod and the adjusting bolt is less than 0.05 mm.

[0013] The bolt strength grades of both the vertical support rod and the adjusting bolt are greater than grade 8.8.

[0014] The beneficial effects of the present utility model are as follows:

[0015] The copper wedge installation support auxiliary device of the present utility model mainly adopts features such as bolt fastening and long hole adjustment. During the installation process of the copper wedge, the length of the assembly of the vertical support rod and the adjusting bolt and the distance between the bolt assemblies can be adjusted according to the size of the crosshead baffle and the wedge distance, thereby fixing the relative distance between the wedges, reducing the installation difficulty of the wedges, and during the alignment process, the position of the wedge can also be adjusted in a timely manner by finely adjusting the bolt distance, reducing the working difficulty of the operator.

[0020] The present utility model will be described in detail below in conjunction with the drawings and specific embodiments.

[0021] Embodiment 1:

[0022] As Figure 1As shown, the copper wedge installation support auxiliary device includes a horizontal support rod 1. The horizontal support rod 1 is used to support the wedge in the horizontal direction and also provides an installation position for other components. A fixed threaded hole 2 is provided at the center of the horizontal support rod 1. Adjusting holes 3 are symmetrically provided on both sides of the fixed threaded hole 2. A bolt assembly 4 is arranged in the adjusting hole 3. The bolt assembly 4 arranged in the adjusting hole 3 restricts the position of the wedge by clamping the end of the bolt with the groove on the surface of the wedge. A vertical support rod 5 is arranged in the fixed threaded hole 2. An adjusting threaded hole 6 is provided at the stud end face of the vertical support rod 5. An adjusting bolt 7 is arranged in the adjusting threaded hole 6. The vertical support rod 5 and the adjusting bolt 7 cooperate to adjust the spacing of the wedge in the vertical direction.

[0023] By positioning the wedges in the horizontal and vertical directions, the positions of the four wedges are made consistent with the positions of the fixed sliding grooves on the main shaft, making it easy for the wedges to enter the main shaft and reducing the installation difficulty.

[0024] Embodiment Two:

[0025] Based on Embodiment One:

[0026] As Figure 2 shown, the cross-section of the horizontal support rod 1 is square, and the parallelism error between the two planes connected to the adjusting hole 3 on the horizontal support rod 1 is less than 0.05 mm, so as to ensure that the heights of the wedges on the left and right sides in the horizontal direction are the same during use and improve the positioning accuracy.

[0027] As Figure 2 shown, the fixed threaded hole 2 is a fine-threaded screw. The fine-threaded screw has the characteristics of good self-locking property and strong anti-loosening ability, which can avoid the connection between the horizontal support rod 1 and the vertical support rod 5 from loosening and causing deviation in positioning.

[0028] As Figure 2 shown, the center distance between the two adjusting holes 3 and the center of the fixed threaded hole 2 is 160 - 230 mm. The adjusting hole 3 is an oblong hole, and the extending direction of the oblong hole is the same as the direction of the horizontal support rod 1. The oblong hole design can adjust the position of the bolt assembly 4 to adapt to wedges of different sizes. And the adjusting hole 3 is a counterbore. The counterbore design can hide the nut of the bolt assembly 4, and when the bolt is tightened, the nut cannot be fixed, resulting in the bolt assembly 4 not being able to be tightened and the wedge in the horizontal direction not being able to be fixed.

[0029] As Figure 1 shown, the bolt assembly 4 includes a bolt and a nut. The nut is located in the counterbore, and the width of the counterbore is between the width of the nut and the diagonal length of the nut, ensuring that the nut cannot rotate significantly in the counterbore and facilitating the tightening of the bolt.

[0030] Embodiment Three:

[0031] Based on Embodiment One:

[0032] As Figure 3 shown, the effective depth of the thread of the vertical support rod 5 is greater than 30 mm. The thread on the vertical support rod 5 extends from the other end opposite to the self-adjusting threaded hole 6 towards the adjusting threaded hole 6. The surface roughness of the end face of the vertical support rod 5 opposite to the adjusting threaded hole 6 is Ra0.4 - 1.6. The adjusting threaded hole 6 uses a fine-pitch thread, which has the characteristics of good self-locking property and strong anti-loosening ability, making the connection between the vertical support rod 5 and the adjusting bolt 7 more stable.

[0033] The surface roughness of the top end of the adjusting bolt 7 is Ra0.4 - 1.6.

[0034] The low roughness of the vertical support rod 5 and the adjusting bolt 7 can make the end face closely adhere to the surface of the wedge, preventing inaccurate positioning caused by uneven contact surfaces.

[0035] When the adjusting bolt 7 is fully screwed into the adjusting threaded hole 6, the minimum length of the assembly of the vertical support rod 5 and the adjusting bolt 7 is 220 mm. When the adjusting bolt 7 is only effectively connected to the adjusting threaded hole 6, the maximum length of the assembly is 250 mm. The length of the assembly can be adjusted to adapt to wedges of different sizes, and the parallelism error of the bolt head of the assembly of the vertical support rod 5 and the adjusting bolt 7 is less than 0.05 mm.

[0036] The bolt strength grade of the vertical support rod 5 and the adjusting bolt 7 is greater than 8.8 grade. The high strength grade can avoid device damage caused by extrusion.

[0037] Working principle: When in use, first place the device into the wedge fixed on the cross plate, make the top end of the vertical support rod 5 fit with the surface of the lower wedge, and then rotate the vertical support rod 5 to adjust the height of the horizontal support rod 1. Stop rotating when the horizontal support rod 1 fits with the surface of the wedge. Slide the bolt assembly 4 in the adjusting hole 3 to adjust the position of the wedge in the horizontal direction. After determining the position, tighten the bolt assembly 4 to fix it. Finally, rotate the adjusting bolt 7 so that its top end contacts the surface of the wedge, ensuring that the distance between the upper and lower wedges is the same as one side of the cross plate. After the fixing work is completed, it can be integrally installed into the main shaft together with the wedge fixing plate, and fine adjustment can be made according to the assembly situation during the assembly process.
