Abstract
Description
Technical Field
[0001] This utility model relates to a spring sleeve device for guide springs, belonging to the field of metallurgical machinery design technology. Background Technology
[0002] The existing guide spring device involves directly inserting the spring between two holes on the support arm, which has the drawback of inconvenient installation and removal of the guide spring. In addition, the spring force cannot be freely adjusted, and the support arm often deviates from the center line due to the weakening of the spring force. This results in excessive force on the guide roller by the rolled piece, causing damage to the guide roller and affecting production efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a spring sleeve device for guide springs that is easy to assemble and disassemble and can adjust the spring force to avoid excessive force on the guide roller caused by the workpiece, which would damage the guide roller.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0005] A spring sleeve device for a guide spring includes two spring mounting plates, which are respectively connected to two support arms. A through threaded hole is provided in the middle of the spring mounting plate, and nuts are threaded onto the outer sides of the two through threaded holes. The two spring mounting plates are used to install the two ends of the spring. The two ends of the spring extend into the through threaded holes and contact the front ends of the two nuts respectively. A guide pin is provided inside the spring, and the two ends of the guide pin extend into the through threaded holes.
[0006] The support arm and the spring mounting plate are connected by welding.
[0007] The spring mounting plate is rectangular.
[0008] The length, width, and height of the cuboid are 58~62mm, 28~32mm, and 28~32mm, respectively.
[0009] The diameter of the through threaded hole is 21~22mm, and the thread length is 1.2~1.8mm.
[0010] The through-threaded hole is formed by first boring it on a lathe and then machining it with a tap.
[0011] The length, width, and height of the cuboid are 60mm, 30mm, and 30mm, respectively.
[0012] The diameter of the through threaded hole is 21.5 mm and the thread length is 1.5 mm.
[0013] The beneficial effects of this utility model are as follows: This utility model provides a spring sleeve device for guide springs. The spring mounting plate has a through threaded hole in the middle, and nuts are screwed onto the outer sides of the two through threaded holes. The nuts can be removed and the spring can be inserted into the through threaded hole, and then the nuts can be installed. When the spring needs to be removed, the process can be reversed. This has the advantage of convenient disassembly and assembly. In addition, the distance between the two nuts can be easily adjusted, thereby adjusting the length of the spring and adjusting the spring force. This avoids excessive force on the guide roller caused by the workpiece, which could damage the guide roller. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the structure of a spring sleeve device for a guide spring according to the present invention;
[0015] The following labels are used in the attached diagram: 1-support arm; 2-spring mounting plate; 3-nut; 4-spring; 5-guide pin; 21-through threaded hole. Detailed Implementation
[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present invention more clearly, and should not be used to limit the protection scope of the present invention.
[0017] Example 1
[0018] like Figure 1 As shown, this utility model discloses a spring sleeve device for a guide spring, including two spring mounting plates 2, which are respectively connected to two support arms 1. A through threaded hole 21 is provided in the middle of the spring mounting plate 2, which is used for mounting and limiting the spring 4. Nuts 3 are threaded onto the outer sides of the two through threaded holes 21, and the two spring mounting plates 2 are used to mount the two ends of the spring 4. The two ends of the spring 4 extend into the through threaded holes 21 and contact the front ends of the two nuts 3 respectively. By rotating the nuts 3, the distance between the two nuts 3 can be adjusted, thereby adjusting the length of the spring 4 and realizing the adjustment of the elastic force. At the same time, the nuts 3 can prevent the spring 4 from coming out of the through threaded holes 21. A guide pin 5 is provided inside the spring 4, with both ends of the guide pin 5 extending into the through threaded holes 21. The guide pin 5 can prevent the spring 4 from deforming excessively from the middle and coming out.
[0019] The working principle of this utility model is as follows: the elastic force of the spring 4 is controlled by the position of the two nuts 3 on the spring mounting plate 2. Specifically, when the nuts 3 are screwed into the inner side of the spring mounting plate 2, the distance between the two nuts 3 becomes smaller, the spring 4 is compressed, and the elastic force of the spring 4 is increased. When screwed out in the opposite direction, the distance between the two nuts 3 becomes larger, the spring 4 is stretched, and the elastic force of the spring 4 decreases, thus achieving free adjustment of the elastic force of the spring 4.
[0020] In this utility model, a through threaded hole is provided in the middle of the spring mounting plate, and nuts are screwed onto the outer sides of the two through threaded holes respectively. The nuts can be removed and the spring can be inserted into the through threaded hole, and then the nuts can be installed. When the spring needs to be removed, the process can be reversed. It has the advantage of convenient disassembly and assembly. In addition, the distance between the two nuts can be easily adjusted, thereby adjusting the length of the spring and adjusting the spring force to avoid excessive force on the guide roller caused by the workpiece, which would damage the guide roller.
[0021] Example 2
[0022] like Figure 1 As shown, this utility model discloses a spring sleeve device for a guide spring, including two spring mounting plates 2, which are respectively connected to two support arms 1. The support arms 1 and the spring mounting plates 2 are welded together. A through threaded hole 21 is provided in the middle of the spring mounting plate 2, which is used for installing and limiting the spring 4.
[0023] The spring mounting plate 2 is a cuboid with a length, width and height of 58~62mm, 28~32mm and 28~32mm respectively. In this embodiment, the dimensions are preferably 60mm, 30mm and 30mm.
[0024] The through-threaded hole 21 is formed by first boring it on a lathe and then machining it with a tap. The diameter of the through-threaded hole 21 is 21~22mm, preferably 21.5mm in this embodiment, and the thread length is 1.2~1.8mm, preferably 1.5mm in this embodiment.
[0025] Two nuts 3 are threaded onto the outer sides of the two through-threaded holes 21, and the threads of the nuts 3 and nuts 3 are matched. Two spring mounting plates 2 are used to mount the two ends of the spring 4. The two ends of the spring 4 extend into the through-threaded holes 21 and contact the front ends of the two nuts 3 respectively. By rotating the nuts 3, the distance between the two nuts 3 can be adjusted, thereby adjusting the length of the spring 4 and realizing the adjustment of the elastic force. At the same time, the nuts 3 can prevent the spring 4 from coming out of the outside of the through-threaded holes 21. A guide pin 5 is provided inside the spring 4. The two ends of the guide pin 5 extend into the through-threaded holes 21. The guide pin 5 can prevent the spring 4 from deforming excessively due to force and coming out.
[0026] The above are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
