Description

Technical Field

[0002] The existing three-drum forming machines have two structural forms: three-drum two-chassis and three-drum three-chassis. Figure 1 As shown in the figure, the three-drum two-chassis means that the belt drum and the forming drum share a chassis to realize the action drive of the two. Although this model has high production efficiency, in terms of structural layout, the forming drum is installed at a position far away from the chassis through its drive shaft, resulting in large deflection during production and cannot be adjusted separately. This is because if the deflection is counteracted by adjusting the tilt setting angle of the chassis, it will affect the production process of the belt drum. Figure 2 As shown, the three-drum three-chassis machine has one chassis for each of the belt drum and the forming drum, and they are arranged on two vertical tracks; this machine model uses independent chassis to make the setting angles of the two independently adjustable, which effectively improves the operation accuracy, but in terms of structural layout, because the belt drum chassis is centrally placed, the belt drum needs to be driven radially to the outside of the line during the production process to meet the composite parts transfer; compared with the three-drum two-chassis machine, the linear position adjustment process of the belt drum and the forming drum is added during the production process, which will inevitably lead to a slower production rhythm and low production efficiency.

[0003] Based on this, considering the advantages and disadvantages of the above two models, it is necessary to design a machine that can still use the structural layout of the original three-drum two-chassis machine model, maintain the belt drum chassis with in-line fitting and no radial movement, so as to separate the drive control of the belt drum from the original chassis, and make the setting angle of the forming drum independently adjustable, so as to further improve the operating accuracy of the equipment.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments are by no means intended to limit the present invention in any way.

[0024] See also Figure 4 and Figure 5 The inline belt drum chassis 2 includes a rotation drive mechanism, an expansion and contraction drive mechanism and a movement drive mechanism arranged on a frame.

[0025] The frame includes a horizontally arranged bottom plate 12, to which a chassis 6 is connected.

[0026] Two groups of sliders 13 are provided on the bottom surface of the bottom plate 12, which can cooperate with the slide rails on the base 5 in the original three-drum two-chassis forming machine, so that the frame is slidably set on the two slide rails of the base 5; specifically, the two groups of sliders 13 are respectively arranged at the four corners of the bottom plate 12, and the setting direction of the sliders 13 is the same as the axial direction of the chassis 6, and the distance between the two sliders in each group of sliders is adapted to the distance between the two slide rails.

[0027] The chassis 6 is used to assemble the expansion and contraction drive mechanism, the rotation drive mechanism, the movement drive mechanism and the belt drum 10. It is specifically a vertically arranged hollow shell with a mounting hole axially provided on the shell. In practical applications, by adjusting the connection fixing angle of the chassis 6 on the bottom plate 12, the arrangement of the belt drum 10 can be adjusted, thereby adjusting the production operation accuracy of the belt drum 10.

[0028] The rotary drive mechanism includes a rotary motor 11 , an externally geared turntable bearing 14 and a belt drum mounting seat 18 .

[0029] The belt drum mounting seat 18 is a cylindrical barrel structure, which is arranged on the front side of the chassis 6 together with the externally toothed turntable bearing 14, and is coaxially arranged with the mounting hole on the chassis 6; the inner ring of the bearing of the externally toothed turntable bearing 14 is fixed on the front side of the chassis 6, and its outer ring of the bearing is fixedly connected to the rear end of the belt drum mounting seat 18, so that the belt drum mounting seat 18 can rotate freely relative to the chassis 6.

[0030] The rotating motor 11 is fixed on the back side of the chassis 6 in such a way that its output shaft is parallel to the axial direction of the mounting hole, and its output shaft passes vertically through a through hole provided on the chassis 6 to the front side of the chassis 6; a transmission gear 22 is sleeved and fixed on the shaft end of the output shaft of the rotating motor 11, which is meshed and connected with the outer gear ring of the externally geared turntable bearing 14.

[0031] In practical applications, the belt drum 10 is sleeved and installed on the outside of the belt drum mounting seat 18. When the rotary motor 11 is driven to rotate, the outer gear ring of the external gear turntable bearing 14 can be driven to rotate through the transmission gear 22, so that the belt drum mounting seat 18 drives the belt drum 10 to rotate synchronously.

[0032] The expansion and contraction driving mechanism includes an expansion and contraction motor 8, a synchronous belt transmission mechanism, a screw group, a turntable bearing 17, a push plate 19 and a guide sleeve 20.

[0033] The guide sleeve 20 is inserted into an axial passage formed by the mounting hole of the chassis 6 and the center hole of the inner ring of the external gear type turntable bearing 14 , and its front end is fixedly connected to the rear end of the belt drum mounting seat 18 .

[0034] The turntable bearing 17 and the push plate 19 are built into the chassis 6 and are coaxially arranged; wherein, the turntable bearing 17 is arranged on the outside of the guide sleeve 20 through its bearing inner ring sleeve, and its bearing outer ring is fixed on the front disk surface of the push plate 19, so that the push plate 19 and the turntable bearing 17 can move synchronously along the axial direction of the guide sleeve 20.

[0035] The lead screw assembly is composed of three lead screws 16, which are evenly arranged along the circumferential direction of the turntable bearing 17 and vertically penetrated on the chassis 6; preferably, one lead screw 16 is arranged on the top side, and the other two lead screws 16 are symmetrically arranged on the bottom side. The two ends of the lead screw of each lead screw 16 are respectively rotatably arranged on the front and rear side walls of the chassis 6 through a rotating bearing, and the lead screw nut is fixed on the back side disk surface of the push disk 19 to drive the push disk 19 to move synchronously in the axial direction.

[0036] The synchronous belt transmission mechanism includes a driving wheel, two guide wheels 23, three synchronous wheels 15 and a synchronous belt 7; wherein the three synchronous wheels are sleeved and fixed on the rear ends of the lead screws of the three lead screws 16 to drive the lead screws to rotate synchronously; the two guide wheels 23 are rotatably arranged on the back side of the chassis 6 in a manner coplanar with the three synchronous wheels 15 and are located under the three synchronous wheels 15; the driving wheel is also arranged in a manner coplanar with the three synchronous wheels 15, below the two guide wheels 23 and at a central position; the synchronous belt 7 is an annular belt, which is sleeved on the outside of the three synchronous wheels 15, bypasses the two guide wheels 23, turns, and is sleeved on the outside of the driving wheel, so that the driving wheel and the three synchronous wheels 15 can rotate synchronously in the same direction.

[0037] The expansion and contraction motor 8 is fixed on the back side of the chassis 6 with its output shaft parallel to the axial direction of the mounting hole, and the end of its output shaft is inserted and fixed in the center hole of the driving wheel to drive the driving wheel to rotate, and then the driving wheel drives the guide wheel 23 and the synchronous wheel 15 in the synchronous belt transmission mechanism to rotate synchronously.

[0038] In practical applications, when the expansion and contraction motor 8 is driven to rotate, the driving wheel rotates, and under the action of the synchronous belt 7, the three synchronous wheels 15 drive the screws of the three lead screws 16 to rotate synchronously in the same direction, and the lead screw nuts of the three lead screws 16 then drive the push plate 19 to move axially, and drive the turntable bearing 17 connected to the push plate 19 to move axially on the guide sleeve 20 synchronously; since the rear ends of the three expansion and contraction connecting rods 21 on the belt drum 10 are connected to the turntable bearing 17, therefore, when the axial movement direction of the turntable bearing 17 is forward, the three expansion and contraction connecting rods 21 are synchronously pushed forward, Thereby, the belt drum 10 is driven to expand; and when the axial movement direction of the turntable bearing 17 is backward, the three expansion and contraction connecting rods 21 are pulled backward synchronously, thereby driving the belt drum 10 to contract; in the above process, since the inner ring of the turntable bearing 17 is fixed on the guide sleeve 20, the guide sleeve 20 can support and guide the turntable bearing 17 while being able to rotate freely with the belt drum mounting seat 18, thereby making the expansion and contraction driving movement of the belt drum 10 and the rotation driving movement of the belt drum 10 can be carried out synchronously, that is, the rotation function and the expansion and contraction function of the belt drum 10 do not affect each other.

[0039] The mobile driving mechanism includes a mobile motor 9, a right-angle reducer, a mobile driving gear and a rack; wherein the mobile motor 9 is horizontally fixed on a base plate 12, the right-angle reducer is fixed on the base plate 12 on one side of the output shaft end of the mobile motor 9, its input shaft is connected to the output shaft of the mobile motor 9 through a coupling, its output shaft is vertically arranged downward and extends to the bottom of the base plate 12 through an opening provided on the base plate 12; the mobile driving gear is sleeved and fixed on the output shaft of the right-angle reducer, the rack is fixed on the inner wall of one side of the slide rail with the tooth surface facing the mobile driving gear, and the mobile driving gear is meshed and connected with the rack.

[0040] In practical applications, by controlling the moving motor 9 to rotate forward or reverse, the frame is driven to slide back and forth along the axial direction on the two slide rails of the base 5, so as to realize the correction effect on the drum in the production process in combination with the feeding system. Figure 6 At the same time, the position of the belt drum 10 and its drive control chassis is adjustable, which is also convenient for maintenance and repair of different chassis, such as Figure 7 shown.

[0041] like Figure 3The figure shows a schematic diagram of the structure of a three-drum three-chassis forming machine formed by assembling the in-line belt-drum chassis of the present embodiment. As shown in the figure, the in-line belt-drum chassis 2 is slidably set on the strip track of the base 5, and is located in front of the original chassis 1 of the three-drum two-chassis forming machine. The original chassis 1 is changed to drive and control two forming drums 3 separately. In the specific assembly process, the main shaft used to control the rotation of the forming drum is directly passed through the axial installation channel formed by the guide sleeve 20 and the belt-drum mounting seat 18 in the in-line belt-drum chassis 2 to the front side of the belt-drum 10, and then the forming drum can be installed. This achieves the maximum retention of the original belt-drum and forming drum interface, is compatible with old equipment tooling, reduces the types of tooling, reduces the user's tooling procurement cost pressure, and reduces the tooling maintenance. type of purpose; on the other hand, the in-line belt drum chassis 2 realizes the separate drive control of the belt drum 10 and the forming drum 3, so that the control accuracy of the two can be adjusted separately, and the purpose of the on-drum correction function combined with the feeding system is achieved, that is, it has the high precision advantage of the three-drum three-stage box; at the same time, the in-line fitting layout chassis is still adopted without radial movement, and does not affect the reciprocating movement of the belt ring 4 installed on the base 5 during the production operation, retaining the efficiency advantage of the original three-drum two-chassis; further, by adopting the three-drum three-chassis forming machine assembled by the in-line belt drum chassis 2, it is possible to achieve both improvement in equipment accuracy and equipment efficiency.
