Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment technology, specifically a multi-roller die with a high-frequency welding station. Background Technology

[0002] Automotive multi-roll forming dies are used to roll-form irregular automotive parts. Most of them consist of multiple rolling stations arranged in a row. After the automotive workpiece enters, each station rolls the workpiece to make its shape, ultimately resulting in an irregular cross-section. The end of the die is equipped with a high-frequency welding station to facilitate subsequent welding.

[0003] However, most existing multi-roll forming dies are fixed structures, which are not convenient for adapting to the rolling of automotive parts of different sizes. At the same time, the existing high-frequency welding station is not accurate enough in positioning when welding irregularly shaped workpieces. Therefore, a multi-roll forming die with a high-frequency welding station is needed to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-roller die with a high-frequency welding station to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-roller pressing die with a high-frequency welding station, comprising a first pressing roller, a second pressing roller, a third pressing roller, a welding assembly, and a control assembly.

[0006] The control assembly consists of three sets, which are connected side-by-side. Inside each set, a first pressure roller, a second pressure roller, and a third pressure roller are sequentially and rotatably engaged. A welding assembly is located on the side end face of the rearmost control assembly.

[0007] The control assembly includes a positioning timing belt, a positioning motor, a driven timing pulley, a driving timing pulley, a limiting assembly, a bidirectional lead screw, and a support assembly. The driving timing pulley is rotatably engaged at the center of the inner end face of the support assembly, and the driven timing pulley is symmetrically engaged at the inner end face of the support assembly with the driving timing pulley as the center. The two sets of driven timing pulleys and the driving timing pulley are meshed and connected by the positioning timing belt. The positioning motor is provided on the upper end face of the support assembly opposite the driving timing pulley. A bidirectional lead screw is fixedly installed at the center of the lower end face of the driven timing pulley, and the limiting assembly is symmetrically threaded to the outer end face of the bidirectional lead screw.

[0008] Preferably, the welding assembly includes a limiting bracket, a servo motor, a fixed slot, a fixed gear ring, a positioning bracket, a drive gear, a fixed motor, and a fixed rotating base. The fixed rotating base is rotatably engaged at the center of the inner end face of the limiting bracket, and a fixed slot is provided on the inner end face of the fixed rotating base. A servo motor is provided on the side end face of the limiting bracket, directly opposite the fixed rotating base. A fixed gear ring is rotatably engaged on the inner end face of the fixed rotating base, and three sets of positioning brackets are evenly spaced on the inner end face of the fixed gear ring. A fixed motor is provided on the outer end face of the fixed rotating base, and a drive gear is provided on the inner end face of the fixed motor.

[0009] Preferably, the limiting component includes a limiting slide for support, a threaded groove is provided at the center of the upper end face of the limiting slide, and a positioning groove is symmetrically provided on the upper end face of the limiting slide with the threaded groove as the center. A fixed guide is provided at the center of the side end face of the limiting slide, and a positioning rotary groove is provided at the center of the side end face of the fixed guide.

[0010] Preferably, the support assembly includes a snap-fit ​​guide seat for limiting the position. The lower end face of the snap-fit ​​guide seat is symmetrically provided with a connecting side plate, and a fixing groove is provided in the middle of the side end face of the connecting side plate. The inner end face of the fixing groove is symmetrically provided with a guide slide shaft.

[0011] Preferably, the fixed gear ring is rotatably engaged with the inner end face of the fixed rotating seat via the fixed slot, and the side end face of the driving gear meshes with the fixed gear ring.

[0012] Preferably, the threaded groove is adapted to the bidirectional lead screw, and the limiting component is threadedly slidably connected to the inner end face of the support component through the adaptation of the threaded groove to the bidirectional lead screw.

[0013] Preferably, the positioning groove is adapted to the guide slide shaft, and the limiting component is slidably engaged inside the support component by adapting to the guide slide shaft through the positioning groove.

[0014] Preferably, the first, second, and third pressure rollers have different radii, and each of the first, second, and third pressure rollers has a snap-fit ​​shaft on its side end face. The first, second, and third pressure rollers are all rotatably snapped into the interior of the positioning groove via the snap-fit ​​shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By setting up a control component, this invention allows for the arbitrary activation of three sets of positioning motors when adapting to different automotive workpieces. The positioning motors can synchronously drive two sets of driven synchronous pulleys to rotate via an active synchronous pulley and a positioning synchronous belt. This enables the driven synchronous pulleys to control the roller spacing of the two opposing sets of limiting components via a bidirectional lead screw, thereby precisely controlling the roller pressing adaptability of the first, second, and third rollers to the automotive workpiece.

[0017] 2. By setting up welding components, the present invention enables the servo motor to drive the fixed rotating seat to rotate laterally when adjusting the welding angle of the automotive workpiece, thereby adjusting its lateral angle. At the same time, the fixed motor can drive the fixed gear ring to rotate longitudinally on the fixed rotating seat through the meshing of the drive gear and the fixed gear ring. This allows for rapid and precise adjustment of any angle of the welding equipment on the upper part of the positioning bracket, improving the accuracy of the welding equipment.

[0030] The invention will be further described below with reference to the accompanying drawings.

[0031] Example 1

[0032] Please see Figure 1-8 One embodiment of the present invention provides a multi-roller pressing die with a high-frequency welding station, comprising a first pressing roller 1, a second pressing roller 2, a third pressing roller 3, a welding assembly 4, and a control assembly 5.

[0033] The control assembly 5 consists of three sets, which are connected side by side. Inside each set of control assemblies 5, a first pressure roller 1, a second pressure roller 2, and a third pressure roller 3 are sequentially rotatably engaged. A welding assembly 4 is provided on the side end face of the control assembly 5 located at the rearmost part.

[0034] The control assembly 5 includes a positioning synchronous belt 51, a positioning motor 52, a driven synchronous belt pulley 53, a driving synchronous belt pulley 54, a limit assembly 55, a bidirectional lead screw 56, and a support assembly 57. The driving synchronous belt pulley 54 is rotatably engaged at the center of the inner end face of the support assembly 57, and the driven synchronous belt pulley 53 is symmetrically engaged at the inner end face of the support assembly 57 with the driving synchronous belt pulley 54 as the center. The two sets of driven synchronous belt pulleys 53 and driving synchronous belt pulleys 54 are meshed and connected by the positioning synchronous belt 51. The positioning motor 52 is set on the upper end face of the support assembly 57 opposite to the driving synchronous belt pulley 54. The bidirectional lead screw 56 is fixedly installed at the center of the lower end face of the driven synchronous belt pulley 53. The limit assembly 55 is symmetrically threaded to the outer end face of the bidirectional lead screw 56.

[0035] The welding assembly 4 includes a limiting bracket 41, a servo motor 42, a fixed slot 43, a fixed gear ring 44, a positioning bracket 45, a drive gear 46, a fixed motor 47, and a fixed rotating seat 48. The fixed rotating seat 48 is rotatably engaged at the center of the inner end face of the limiting bracket 41, and a fixed slot 43 is provided on the inner end face of the fixed rotating seat 48. The servo motor 42 is provided on the side end face of the limiting bracket 41 opposite to the fixed rotating seat 48. The fixed gear ring 44 is rotatably engaged on the inner end face of the fixed rotating seat 48, and three sets of positioning brackets 45 are evenly spaced on the inner end face of the fixed gear ring 44. The fixed motor 47 is provided on the outer end face of the fixed rotating seat 48, and a drive gear 46 is provided on the inner end face of the fixed motor 47.

[0036] The limiting component 55 includes a limiting slide 553 for support. A threaded groove 552 is provided at the center of the upper end face of the limiting slide 553, and a positioning groove 551 is symmetrically provided on the upper end face of the limiting slide 553 with the threaded groove 552 as the center. A fixed guide seat 554 is provided at the center of the side end face of the limiting slide 553, and a positioning rotary groove 555 is provided at the center of the side end face of the fixed guide seat 554.

[0037] The support assembly 57 includes a snap-fit ​​guide seat 571 for limiting the position. The lower end face of the snap-fit ​​guide seat 571 is symmetrically provided with a connecting side plate 572, and a fixing groove 573 is provided in the middle of the side end face of the connecting side plate 572. The inner end face of the fixing groove 573 is symmetrically provided with a guide slide shaft 574.

[0038] The fixed gear ring 44 is rotatably engaged with the inner end face of the fixed rotating seat 48 through the fixed slot 43, and the side end face of the driving gear 46 meshes with the fixed gear ring 44, which facilitates the rapid and precise adjustment of the welding angle of the equipment in the future.

[0039] The threaded groove 552 is adapted to the bidirectional lead screw 56, and the limiting component 55 is threadedly slidably connected to the inner end face of the support component 57 through the threaded groove 552 and the bidirectional lead screw 56. This facilitates the adaptive adjustment of the rolling thickness of the first roller 1, the second roller 2 and the third roller 3 inside the three sets of limiting components 55.

[0040] The positioning slide 551 is adapted to the guide slide 574, and the limiting component 55 is slidably engaged inside the support component 57 through the adaptation of the positioning slide 551 and the guide slide 574. The sliding adaptation of the positioning slide 551 and the guide slide 574 facilitates providing sufficient limiting basis for the subsequent displacement of the limiting component 55.

[0041] The first roller 1, the second roller 2, and the third roller 3 have different radii, and each of them has a snap-fit ​​shaft on its side end face. The first roller 1, the second roller 2, and the third roller 3 are all rotatably snapped into the positioning slot 555 through the snap-fit ​​shaft. The automotive workpiece enters the three stations respectively. The first roller 1, the second roller 2, and the third roller 3 can perform shaping roller pressing on the automotive workpiece at various angles, which improves the efficiency of roller pressing the workpiece cross section. The snap-fit ​​shaft can effectively improve the stability of the first roller 1, the second roller 2, and the third roller 3 in the limiting assembly 55.

[0042] Working Principle: Before use, the user can position the corresponding welding equipment on the upper part of the positioning bracket 45. If the workpiece needs to be rolled, the user can guide the workpiece from the first roller 1 through the external material guide device. During rolling, the first roller 1, the second roller 2, and the third roller 3 have different structures, which can shape the rolled automotive workpiece from various angles. If it is necessary to adapt to workpieces of different thicknesses, the user can start any one of the positioning motors 52 on the upper part of the three sets of control components 5. The positioning motor 52 can drive the bottom active synchronous pulley 54 to rotate. The active synchronous pulley 54 can drive the two sets of driven synchronous pulleys 53 to mesh and rotate through the positioning synchronous belt 51, thereby causing the driven synchronous pulleys 53 to drive the bottom bidirectional lead screw 56 to rotate, so that... The bidirectional lead screw 56 can be threadedly connected to the threaded slide groove 552, thereby driving the two sets of limit components 55 to move up and down synchronously. This allows for rapid and precise adjustment of the distance between the first pressure roller 1, the second pressure roller 2, or the third pressure roller 3, facilitating precise rolling operations on different automotive workpieces. When welding the rolled automotive workpiece, if the welding angle needs to be positioned, the user can start the servo motor 42. The servo motor 42 can drive the fixed rotating seat 48 to rotate laterally. At the same time, the fixed motor 47 can mesh with the fixed gear ring 44 through the drive gear 46, thereby driving the fixed gear ring 44 to rotate on the fixed rotating seat 48. This allows for rapid and precise adjustment of any angle of the welding equipment on the positioning bracket 45, improving the efficiency of automotive workpiece processing.
