Description

Technical Field

[0001] This invention relates to the field of raw material conveying technology, and more specifically, to a feeding device for processing automotive radiator brackets. Background Technology

[0002] With the rapid development of the automotive industry, especially the popularization of new energy vehicles, the demand for automotive radiator brackets is increasing daily. Specifically regarding automotive radiators, which need to be fixed to the vehicle using brackets, these brackets are typically made by punching multiple sections from a single metal profile. The processing of the metal profile is mainly done using a bracket processing and cutting machine, which has a pusher and a stamping device. The metal profile is placed on the pusher, which pushes it towards the stamping device, where it is punched. The resulting bracket is then further processed before use. Stable feeding and precise positioning of the metal profile are crucial to ensuring the punching quality, directly affecting the bracket's accuracy and yield rate.

[0003] However, when punching metal profiles, a single limiting groove is typically used to restrict the profile's movement. This not only limits the size of the metal profiles that can be accommodated, but also creates a gap between the groove and the profile, as the profile needs to pass easily through the groove. This gap causes the profile to shift within the groove under immense pressure when the punch contacts it. Furthermore, the pusher may cause the profile to deflect during transport, leading to punching deviations, poor precision in the resulting brackets, and even beveled cuts, thus increasing the scrap rate.

[0004] Therefore, in order to solve the above-mentioned technical problems, the present invention proposes a feeding device for processing automotive radiator brackets. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a feeding device for processing automotive radiator brackets.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for processing automotive radiator brackets, used in a bracket processing and cutting machine, the bracket processing and cutting machine including a stamping device, the feeding device including a conveying limiting device, the conveying limiting device being configured corresponding to the stamping device, the conveying limiting device pressing and limiting the metal profile during feeding; The conveying limiting device includes a driving mechanism and two symmetrically arranged extrusion components. The driving mechanism and the extrusion components are mounted inside the bracket processing and cutting machine via a fixed base. The extrusion assembly includes a transmission mechanism and a pressure roller mechanism disposed on the transmission mechanism. The transmission mechanism is connected to the fixed base and the drive mechanism respectively. The drive mechanism drives the pressure roller mechanism to move through the transmission mechanism. Two transmission mechanisms, driven by the drive mechanism, cause the pressure roller mechanism to abut against the surface of the metal profile and limit the movement range of the metal profile; a processing zone is formed between the two transmission components, and the stamper completes punching of the metal profile through the processing zone.

[0007] Furthermore, the driving mechanism is mounted on the fixed base. The driving mechanism includes a driver and a transmission component. The driving end of the driver is connected to the transmission component, and a first support rod and a second support rod are rotatably connected to both sides of the transmission component.

[0008] Furthermore, one of the transmission mechanisms includes a first transmission rod, a first support rod rotatably connected to the first transmission rod, a first slot is provided on the first transmission rod, a first pin is inserted into the first slot, a first pin hole is provided on the fixed base for the first pin to pass through, a first extension rod is provided on the first transmission rod, a bushing is provided on the first extension rod, and a pressure roller mechanism is provided on the bushing. Another transmission mechanism includes a second transmission rod, a second support rod rotatably connected to the second transmission rod, a second slot is provided on the second transmission rod, a second pin is inserted into the second slot, a second pin hole is provided on the fixed base for the second pin to pass through, a second extension rod is provided on the second transmission rod, a bushing is provided on the second extension rod, and a pressure roller mechanism is provided on the bushing.

[0009] Furthermore, the bushings provided on the first extension rod and the second extension rod are multiple.

[0010] Furthermore, the pressure roller mechanism includes a shaft and rollers, the rollers are disposed at both ends of the shaft, the bushing has a sliding groove for the shaft to pass through, and the rollers are fixed to the shaft by fixing bolts.

[0011] Furthermore, the bushing is provided with an adjustment mechanism, which includes a screw. The bushing has a sleeve hole through which the screw passes. The screw extends into the slide groove through the sleeve hole and is rotatably disposed in the bushing. The shaft has a threaded hole for the screw to be threadedly connected. The screw is threadedly connected to the shaft, and the shaft moves in the slide groove by rotating the screw.

[0012] Furthermore, a guide shaft is also provided inside the bushing, and a guide hole is provided on the shaft for the guide shaft to pass through. The guide shaft is slidably connected to the shaft through the guide hole, and the guide shaft guides the movement of the shaft.

[0013] Furthermore, the outer surface of the roller is covered with a warning layer made of an elastic material, which is compressed when the roller is pressed tightly against the surface of the metal profile.

[0014] Furthermore, the fixing base is provided with screws at positions corresponding to the first pin and the second pin. The screws can extend into the first pin hole and abut against the first pin, and the screws can extend into the second pin hole and abut against the second pin.

[0015] Furthermore, the first transmission rod is rotatably mounted on the fixed base via the first pin, and the second transmission rod is rotatably mounted on the fixed base via the second pin. When the transmission component moves upward, the end of the first and second transmission rods connected to the support rod is raised, and the end of the first and second transmission rods connected to the extension rod moves downward and drives the pressure roller mechanism to move downward to press the metal profile.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The feeding device of this invention effectively solves the problem of insufficient limiting of metal profiles during conveying or punching in the prior art by setting a conveying limit device. The drive mechanism drives the first transmission rod and the second transmission rod in linkage, so that the pressure roller mechanism on the extension rod accurately presses the metal profile, limiting the deviation and warping of the profile during conveying and punching. The setting of multiple bushings and pressure roller mechanisms can not only accommodate wider metal profiles, but also press multiple profiles at the same time, improving the versatility of the equipment and processing efficiency, and significantly reducing the punching deviation and scrap rate caused by profile deflection.

[0017] The adjustment mechanism on the bushing allows for individual adjustment of the height of the corresponding pressure roller mechanism. Combined with the guiding effect of the guide shaft, it can specifically solve problems such as thickness deviation of metal profiles, uneven pressure caused by simultaneous processing of multiple profiles, or component aging. With the warning layer or pressure sensor on the roller, it can intuitively judge and ensure that the pressure of each pressure roller on the profile is within a reasonable range, further improving punching accuracy and processing stability, and providing a reliable guarantee for the efficient and high-quality production of automotive radiator brackets.

Detailed Implementation

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

[0021] Based on the above problems, this application proposes a feeding device for processing automotive radiator brackets. On the basis of the above mechanism, a conveying limiting device 1000 is set in the bracket processing and cutting machine 2000 at the position corresponding to the stamping machine 2001. When the metal profile 3000 moves, it is limited to fit inside the bracket processing and cutting machine 2000. When the stamping machine 2001 stamps the metal profile 3000, the conveying limiting device 1000 can press tightly against both ends of the metal profile 3000 to prevent it from tilting or deflecting during stamping.

[0022] Please see Figures 1 to 2 The conveying limiting device 1000 includes a fixed base 100, which is bolted to the support processing and cutting machine 2000. A drive mechanism 200 is provided on the fixed base 100. The fixed base 100 is connected to a first transmission rod 300 and a second transmission rod 400 through the drive mechanism 200. The drive mechanism 200 includes a driver 201 provided on the fixed base 100. The driver 201 can be a cylinder, a hydraulic device, or an electric push rod. The driver 201 is connected to a controller. A transmission component 202 is connected to the drive end of the driver 201. A first support rod 203 and a second support rod 204 are respectively connected to both sides of the transmission component 202 through a rotating shaft. The first support rod 203 and the second support rod 204 can rotate based on the transmission component 202 through the rotating shaft.

[0023] The other end of the first support rod 203 is connected to the first transmission rod 300 via a rotating shaft, allowing rotation between the first support rod 203 and the first transmission rod 300. The first transmission rod 300 has a first slot 302, into which a first pin 303 is inserted. The fixed base 100 has a first pin hole 102 through which the first pin 303 passes. After the first pin 303 passes through the first pin hole 102 and the first slot 302, the first transmission rod 300 can rotate based on the fixed base 100.

[0024] The other end of the second support rod 204 is connected to the second transmission rod 400 via a rotating shaft, allowing the second support rod 204 and the second transmission rod 400 to rotate. The second transmission rod 400 has a second slot 402, into which a second pin 403 is inserted. The fixed base 100 has a second pin hole 103 through which the second pin 403 passes. After the second pin 403 passes through the second pin hole 103 and the second slot 402, the second transmission rod 400 can rotate based on the fixed base 100.

[0025] To prevent the first pin 303 or the second pin 403 from loosening and disengaging from the fixing base 100, a screw 101 is provided on the fixing base 100 at the position corresponding to the first pin 303 and the second pin 403. Tightening the screw 101 will cause the screw 101 to abut against the first pin 303 or the second pin 403, thereby limiting the first pin 303 and the second pin 403.

[0026] The other end of the first transmission rod 300 is provided with a first extension rod 301, and the other end of the second transmission rod 400 is provided with a second extension rod 401. A processing area 900 is formed between the first extension rod 301 and the second transmission rod 400. The stamping device 2001 is located above the processing area 900, which facilitates the normal operation of the stamping device 2001. One or more bushings 500 are connected to one end of the first extension rod 301 and one end of the second transmission rod 400, and a pressure roller mechanism 600 is provided on the bushing 500.

[0027] The principle is as follows: by controlling the movement of the driver 201, the transmission component 202 is driven to move up and down. For example, when the transmission component 202 moves upward, the first support rod 203 will drive the first transmission rod 300 to move upward. Since the first transmission rod 300 is rotatably mounted on the fixed seat 100 through the first pin 303, the end of the first transmission rod 300 connected to the first support rod 203 is raised by lever principle. Therefore, the end of the first transmission rod 300 connected to the first extension rod 301 will move downward, which will drive the pressure roller mechanism 600 mounted on the bushing 500 to move downward. This causes the pressure roller mechanism 600 to press against the assembled metal profile 3000, pressing the metal profile 3000 tightly and preventing the metal profile 3000 from deflecting during conveying or stamping.

[0028] Furthermore, multiple bushings 500 can be provided, so multiple pressure roller mechanisms 600 can also be provided, thereby enabling the compression of wider metal profiles 3000, and also enabling the compression of multiple metal profiles 3000 simultaneously.

[0029] like Figure 3 As shown, the pressure roller mechanism 600 includes a shaft 601, with rollers 602 respectively provided at both ends of the shaft 601. The rollers 602 are mounted on the shaft 601 by fixing bolts 603. The bushing 500 has a sliding groove 501 for the shaft 601 to pass through.

[0030] Furthermore, to facilitate observation of the pressure exerted by the pressure roller mechanism 600 on the metal profile 3000, a pressure sensor can be installed on the drive mechanism 200 for detection. This application also provides another method for determining whether the pressure roller mechanism 600 is applying appropriate pressure to the metal profile 3000, such as... Figure 7As shown, a warning layer 6021 is covered on the outer circular surface of the roller 602. The warning layer 6021 is made of elastic material. When the roller 602 is pressed tightly against the surface of the metal profile 3000, the warning layer 6021 will be compressed. When the part of the warning layer 6021 in contact with the metal profile 3000 is squeezed into a line, it indicates that the pressure applied by the roller 602 to the metal profile 3000 is sufficient, making it easy for the operator to observe.

[0031] Because the thickness of the metal profile 3000 may vary in the horizontal or vertical direction, or when multiple metal profiles 3000 are punched at the same time, the thickness of the metal profile 3000 in the horizontal or vertical direction may vary. Since it is driven by a general driver 201, the pressure applied to the metal profile 3000 by each roller 602 may be inconsistent. This may even cause the warning layer 6021 on some rollers 602 to be compressed to 0.5 cm, while some rollers 602 may not even be in contact with the metal profile 3000.

[0032] The problem isn't just caused by the thickness difference of the 3000 metal profile itself; after prolonged use of the entire device, component aging and displacement can also cause this issue.

[0033] Based on the above-mentioned problems, an adjustment mechanism 700 is provided on the sleeve in the above-mentioned embodiment. The adjustment mechanism 700 can adjust the corresponding pressure roller mechanism 600 individually, so that the roller 602 can be pressed against the surface of the metal profile 3000.

[0034] like Figures 3 to 4 As shown, the adjusting mechanism 700 includes a screw 701. A bushing 500 has a sleeve hole 502 through which the screw 701 passes. The screw 701 enters the slide groove 501 through the sleeve hole 502 and is rotatably mounted within the bushing 500 via a bearing. A shaft 601 is inserted into the slide groove 501 and can move up and down within it. The shaft 601 has a threaded hole 604 for threaded connection of the screw 701. Figure 5 As shown, rotating the screw 701 causes the shaft 601 to move up and down within the slide groove 501 under the action of the threaded connection, thereby driving the roller 602 to move up and down based on the bushing 500. This allows for the adjustment of the roller 602, thereby adjusting the clamping force between different rollers 602 and the metal profile 3000 according to the actual situation, so that the pressure exerted by each roller 602 on the metal profile 3000 is within a certain range.

[0035] To prevent the threaded connection between the screw 701 and the shaft 601 from loosening, a limiting member 702 is also threaded onto the screw 701. The limiting member 702 abuts against the bushing 500 to limit the rotation of the screw 701.

[0036] In addition, to avoid deviation between the pressure rollers at both ends of the same shaft 601, a guide shaft 800 is provided inside the bushing 500. A guide hole 605 is provided on the shaft 601 for the guide shaft 800 to pass through, thereby guiding the movement of the shaft 601 and making the sliding of the shaft 601 smoother.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
