Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot-rolled spring production and processing technology, and in particular to a feeding guide tool for hot-rolled springs. Background Technology
[0002] Hot-rolled springs, also known as large springs or thermoformed springs, are springs manufactured through a hot-rolling process. They are characterized by large wire diameter, high load-bearing capacity, and wide application.
[0003] Hot-rolled springs typically have a large wire diameter, which makes them difficult to fit well with the shock absorber base. Therefore, it is necessary to flatten the end of the spring by forging to make the end fit with the shock absorber base. During the rolling production process, it is necessary to control the position of the flattened end to enter the rolling mold vertically.
[0004] However, manually controlling the flattened end angle cannot achieve automatic continuous production. At the same time, the rod temperature is very high, which poses an operational risk. If the angle is automatically rotated by signal control, the harsh production environment, with frequent dust such as oxide scale, may cause the sensor signal to misinterpret, which may lead to the motor gear jamming and affect normal production.
[0005] Therefore, we propose a novel feeding guide fixture for hot-rolled springs. Utility Model Content
[0006] The purpose of this invention is to solve the problems in the existing technology where the angle of the flattened end is controlled manually, which cannot achieve automatic continuous production. At the same time, the high temperature of the rod poses an operational risk. If the angle is automatically rotated by signal control, the harsh production environment, with frequent dust such as oxide scale, may cause the sensor signal to misinterpret, which may lead to the motor gear jamming and affect normal production.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a feeding and guiding fixture for hot-rolled springs, comprising a base, a rolling die connected to the rear end of the surface of the base, an adjusting guide assembly connected to one side of the rolling die, the adjusting guide assembly comprising a fixing frame, a slot longitudinally formed inside the fixing frame, two sets of first bolts inserted into the slot, a connecting frame connected to the front end of the two sets of first bolts, threaded holes formed on the surface of the connecting frame, support frames connected to both sides of the connecting frame, a bearing body disposed inside the support frame, an adjusting groove formed on the surface of the connecting frame, and a second bolt inserted into the adjusting groove.
[0008] Furthermore, the second bolt passes through the adjustment groove and forms a threaded connection with the support frame. The adjustment groove is arc-shaped, which allows for convenient adjustment of the angle of the support frame.
[0009] Furthermore, after the first bolt passes through the slot, it forms a threaded connection with the connecting bracket, which allows the adjustment angle to be fixed.
[0010] Furthermore, the upper and lower ends of the support frame are connected to a convenient disassembly and assembly component, which includes a sleeve. The convenient disassembly and assembly component can facilitate the disassembly and replacement of the bearing body.
[0011] Furthermore, a telescopic spring is provided inside the sleeve, and a plug rod is inserted inside the telescopic spring. A pull block is connected to the top of the plug rod, and the telescopic spring can easily push the plug rod to fix the bearing body.
[0012] Furthermore, a push plate is fixedly connected to the surface of the insertion rod, and a hot-rolled spring body is provided on the inner side of the four sets of bearing bodies. The push plate can be easily pushed by the telescopic spring.
[0013] Furthermore, the front end of the hot-rolled spring body is a flat end, and the push plate and the telescopic spring form an elastic structure. The design of the elastic structure can achieve the fixation of the bearing body.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] 1. In this utility model, when feeding the hot coil spring body, the feeding angle of the flattened end can be guided by four sets of bearing bodies to ensure that it can enter the coiling mold vertically for fixing, thereby achieving stable and continuous production. Furthermore, the angle of the bearing body can be adjusted by the fixing method of the first bolt and the second bolt, which increases the applicability of the device.
[0016] 2. In this utility model, when the bearing body is damaged and needs to be replaced after long-term use, the two sets of pull blocks can be pulled up and down at the same time, so that the insertion rod no longer limits the bearing body. Then the bearing body can be removed for replacement, which improves the efficiency of disassembly and assembly of the bearing body. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Examples, such as Figure 1 - Figure 3 As shown, this utility model provides a feeding guide fixture for hot-rolled springs, including a base 1. A rolling die 2 is connected to the rear end of the surface of the base 1. An adjusting guide assembly 3 is connected to one side of the rolling die 2. The adjusting guide assembly 3 includes a fixing frame 301. A slot 302 is longitudinally opened inside the fixing frame 301. Two sets of first bolts 303 are inserted into the slot 302. A connecting frame 304 is connected to the front end of the two sets of first bolts 303. A threaded hole 305 is opened on the surface of the connecting frame 304. Support frames 306 are connected to both sides of the connecting frame 304. A bearing body 307 is provided inside the support frame 306. An adjusting groove 308 is opened on the surface of the connecting frame 304. A second bolt 309 is inserted into the adjusting groove 308.
[0025] like Figure 3 As shown, the second bolt 309 passes through the adjustment groove 308 and forms a threaded connection with the support frame 306. The adjustment groove 308 is arc-shaped, which can facilitate the adjustment of the angle of the support frame 306.
[0026] like Figure 2 and Figure 3 The first bolt 303 passes through the slot 302 and forms a threaded connection with the connecting bracket 304. The angle can be fixed by means of the threaded connection.
[0027] like Figure 4 As shown, the upper and lower ends of the support frame 306 are connected to the easy disassembly and assembly component 4. The easy disassembly and assembly component 4 includes a sleeve 401. The easy disassembly and assembly component 4 can facilitate the disassembly and replacement of the bearing body 307.
[0028] like Figure 1 and Figure 4 As shown, a telescopic spring 402 is provided inside the sleeve 401, and a rod 405 is inserted into the telescopic spring 402. A pull block 403 is connected to the top of the rod 405. The telescopic spring 402 can easily push the rod 405 to fix the bearing body 307.
[0029] like Figure 1 and Figure 4 As shown, a push plate 404 is fixedly connected to the surface of the insertion rod 405, and a hot-rolled spring body 5 is provided on the inner side of the four sets of bearing bodies 307. The push plate 404 can be easily pushed by the telescopic spring 402.
[0030] like Figure 4 As shown, the front end of the hot coil spring body 5 is a flat end, and the push plate 404 and the telescopic spring 402 form an elastic structure. The design of the elastic structure can fix the bearing body 307.
[0031] The overall effect of this embodiment is as follows: When the front flat end of the hot-rolled spring body 5 needs to be inserted into the rolling mold 2 for fixation, the angle correction during the feeding process can be achieved through four sets of inclined bearing bodies 307. Furthermore, without the need for sensor signal control, interference from impurities such as oxide scale is avoided. Automatic guiding is achieved through the mechanical structure. After loosening the two sets of first bolts 303, the height of the support frame 306 can be adjusted up and down through the slot 302. Then, tightening the first bolts 303 fixes the height, thus achieving the purpose of adjusting the bearing body 307. By loosening the two sets of second bolts 309, the adjustable support can be rotated within the adjustment slot 308. The tilt angle of the support frame 306 is then fixed by tightening the second bolt 309. When the bearing body 307 needs to be replaced after long-term use, both sets of pull blocks 403 can be pulled up and down simultaneously. This allows the pull blocks 403 to push the push plate 404 through the insertion rod 405 to compress the telescopic spring 402, and to pull the insertion rod 405 out of the bearing body 307. The bearing body 307 can then be removed, and the new bearing body 307 can be placed in the support frame 306. The two sets of pull blocks 403 are then released, and the elastic force of the telescopic spring 402 pushes the push plate 404 to drive the insertion rod 405 to be inserted into the upper and lower ends of the bearing body 307 for fixation.
[0032] Working principle: When feeding the hot-rolled spring body 5, the feeding angle of the flattened end can be guided by four sets of bearing bodies 307 to ensure that it can enter the rolling mold 2 vertically for fixing, thereby achieving stable and continuous production. In addition, the angle of the bearing body 307 can be adjusted by the fixing method of the first bolt 303 and the second bolt 309, which increases the applicability of the device. When the bearing body 307 is damaged and needs to be replaced after long-term use, the two sets of pull blocks 403 can be pulled up and down at the same time, so that the insertion rod 405 no longer limits the bearing body 307. Then the bearing body 307 can be removed for replacement, which improves the disassembly and assembly efficiency of the bearing body 307.
[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
