Description

Technical Field

[0001] The present invention relates to the field of cookware processing equipment, in particular to a spinning machine capable of rapidly processing a thick rim of cookware.Background

[0002] In the cookware production industry, compared with a conventional drawing process, the spinning processing technology is beneficial to saving raw materials and can further process some cookware types which cannot be formed by a common press.

[0003] If cookware structure has a thick rim, the overall structural strength of the cookware is effectively improved, which is beneficial to prolonging the service life of the cookware and improving the user experience of the cookware. However, when a spinning machine on the market performs a spinning treatment on a circular sheet base material, the thick rim structure of the cookware cannot be directly formed by spinning.

[0004] To improve the spinning technology to rapidly process the thick rim of the cookware by the spinning technology is the technical problem hard to solve in the industry.Summary

[0005] To solve the above problem, the present invention provides a spinning machine capable of rapidly processing a thick rim of cookware, which solves the problem that cookware with a thick rim cannot be rapidly processed by a conventional spinning method.

[0006] The technical solution used by the present invention is as follows: A spinning machine capable of rapidly processing a thick rim of cookware includes a worktable, a spindle and a base material pressing mechanism are rotatably connected to the worktable, the worktable is provided with a power device for driving the spindle to rotate, and a mounting table and a forming die are connected to the spindle; the spinning machine further includes a positioning plate, a mounting base is rotatably connected to the positioning plate, and a rotary driving device for driving the mounting base is arranged on the positioning plate; an X-direction driving device for adjusting a horizontal position of the positioning plate and a Z-direction driving device for adjusting the height of the positioning plate are arranged on the worktable; a spinning wheel is rotatably connected to the mounting base, the spinning wheel includes a first extrusion protrusion and a second extrusion protrusion, a transition annular surface is arranged between the first extrusion protrusion and the second extrusion protrusion, the outer diameter of the first extrusion protrusion is greater than that of the second extrusion protrusion, and the transition annular surface is sloped towards one side of the second extrusion protrusion.

[0007] Through the above technical solution, when the circular sheet base material is spun by the spinning wheel, the first extrusion protrusion is mainly used to apply a pressure to the circular sheet base material, so that the circular sheet base material is bent and presses into the surface of the forming die; in the spinning process of the spinning wheel, the first extrusion protrusion thins the circular sheet base material, and the thickness of the circular sheet base material located outside the transition annular surface and the second extrusion protrusion is gradually accumulated and increased. When the spinning action of the spinning wheel is ended, a thickened part located outside the transition annular surface and the second extrusion protrusion forms the thick rim of the cookware. The present invention can rapidly spin the circular sheet base material to the cookware with the thick rim on a path fitting the surface contour of the forming die. In addition, the arrangement of the transition annular surface is also beneficial for a metal material on the circular sheet base material to be accumulated and thickened toward the direction of the second extrusion protrusion, so that the processing efficiency of the thick rim is higher.

[0008] Furthermore, the transition annular surface is cone-shaped, the transition annular surface and the first extrusion protrusion are in smooth transition, and the transition annular surface and the second extrusion protrusion are in smooth transition.

[0009] Through the above technical solution, when the pressure on the circular sheet base material from the first extrusion protrusion is transitioned to the pressure from the transition annular surface, the pressure changes more uniformly. This avoids the formation of sharp parts between the first extrusion protrusion and the transition annular surface, which could otherwise damage the surface of the circular sheet base material and affect the spinning effect. When the metal material on the circular sheet base material is extruded toward the corners of the transition annular surface and the second extrusion protrusion, the arrangement mode in which the transition annular surface and the second extrusion protrusion are in smooth transition can effectively reduce the frictional force generated between the spinning wheel and the circular sheet base material, so that the spinning wheel can be used more smoothly.

[0010] Furthermore, the outer side wall of the first extrusion protrusion is a right circular cylindrical surface.

[0011] Through the above technical solution, when the first extrusion protrusion extrudes the circular sheet base material, the contact area between the first extrusion protrusion and the circular sheet base material is larger, and after the circular sheet base material is extruded by the first extrusion protrusion, the formed surface is smoother and more compact.

[0012] Furthermore, the outer side wall of the second extrusion protrusion is a right circular cylindrical surface.

[0013] Through the above technical solution, the outer side wall of the first extrusion protrusion and the outer side wall of the second extrusion protrusion are coaxially arranged. After the circular sheet base material is subjected to spinning processing by the spinning wheel, the thickness of the formed thick rim is more uniform. The strength of the structure along the extension of the thick rim on the cookware is more uniform.

[0014] Furthermore, a deflection angle formed between the surface of the transition annular surface and the outer side wall of the first extrusion protrusion is 40-50 degrees.

[0015] Through the above technical solution, when the spinning wheel performs the spinning processing, if the deflection angle is too small, the effect that the metal material in the circular sheet base material extruded is accumulated and thickened outside the transition annular surface is insignificant, making it difficult to process the thick rim structure of the cookware. If the deflection angle is too large, the extrusion force between the transition annular surface and the circular sheet base material is too large, which is prone to cause an interrupted spinning process as the spinning wheel cannot proceed. The deflection angle is set reasonably, so that the spinning wheel considers both the processing and forming efficiency of the thick rim and the smoothness of the working process.

[0016] Furthermore, a range of the first extrusion protrusion extending in an axial direction of the spinning wheel is a distance a, a range of the second extrusion protrusion extending in the axial direction of the spinning wheel is a distance b, and the distance a is less than the distance b.

[0017] Through the above technical solution, the effect of accumulating and thickening the metal material of the circular sheet base material outside the second extrusion protrusion and the effect of preventing the edge warping of the circular sheet base material are further improved, facilitating use.

[0018] Furthermore, the X-direction driving device includes a fixed plate and a first linear module, and the fixed plate is fixedly connected to the worktable; the Z-direction driving device includes a movable plate and a second linear module, the first linear module is transversely arranged, the first linear module is connected to the fixed plate and the movable plate, the second linear module is vertically arranged, and the second linear module is connected to the movable plate and the positioning plate; and the rotary driving device includes a connecting base and an adjusting motor, the connecting base is fixedly connected to the positioning plate, the adjusting motor is fixedly connected to the connecting base, an output end of the adjusting motor is in transmission connection to the mounting base, and a rotation axis of the mounting base and a traveling direction of the X-direction driving device are staggered with each other.

[0019] Through the above technical solution, the linear module features accurate positioning, high rigidity, difficulty in deformation, and high load capacity, and the adjusting motor can precisely position the deflection angle of the mounting base.

[0020] Furthermore, the base material pressing mechanism includes a fixed frame, a fixed column, a movable seat, a rotation axis, a pressing plate, and an air cylinder, both the fixed frame and the fixed column are fixedly connected to the worktable, the movable seat is vertically and slidably connected to the fixed column, the rotation axis is vertically and rotatably connected to the movable seat, the bottom end of the rotation axis is fixedly connected to the pressing plate, and the air cylinder is mounted on the fixed frame and an output end of the air cylinder is connected to the movable seat; and the power device is a driving motor, and an output end of the driving motor is in transmission connection to the spindle.

[0021] Through the above technical solution, the base material pressing mechanism is reasonable in structure and accurate in positioning, and can effectively and rapidly press the circular sheet base material by using the pressing plate. When a cookware blank and the circular sheet base material are driven to rotate, the pressing plate and the rotation axis rotate therewith.Brief Description of Figures

[0028] Referring to FIGS. 1, 4, and 5, a spinning machine capable of rapidly processing the thick rim of cookware includes a worktable 1. A spindle 2 and a base material pressing mechanism are rotatably connected to the worktable 1. The worktable 1 is provided with a power device for driving the spindle 2 to rotate, and a mounting table 3 and a forming die 4 are connected to the spindle 2. The spinning machine further includes a positioning plate 5, a mounting base 6 is rotatably connected to the positioning plate 5, and a rotary driving device for driving the mounting base 6 is arranged on the positioning plate 5. An X-direction driving device for adjusting a horizontal position of the positioning plate 5 and a Z-direction driving device for adjusting the height of the positioning plate 5 are arranged on the worktable 1. A spinning wheel 7 is rotatably connected to the mounting base 6. The spinning wheel 7 includes a first extrusion protrusion 701 and a second extrusion protrusion 702. A transition annular surface 703 is arranged between the first extrusion protrusion 701 and the second extrusion protrusion 702. The outer diameter of the first extrusion protrusion 701 is greater than that of the second extrusion protrusion 702, and the transition annular surface 703 is sloped towards one side of the second extrusion protrusion 702.

[0029] When the circular sheet base material is spun by the spinning wheel 7, the first extrusion protrusion 701 is mainly used to apply a pressure to the circular sheet base material, so that the circular sheet base material is bent and presses towards the surface of the forming die 4. In the spinning process of the spinning wheel 7, the first extrusion protrusion 701 thins the circular sheet base material, and the thickness of the circular sheet base material located outside the transition annular surface 703 and the second extrusion protrusion 702 is gradually accumulated and increased. When the spinning action of the spinning wheel 7 is ended, a thickened part located outside the transition annular surface 703 and the second extrusion protrusion 702 forms the thick rim 213 of the cookware 21. The present invention can rapidly spin the circular sheet base material to the cookware 21 with the thick rim 213 on a path fitting the surface contour of the forming die 4. In addition, the arrangement of the transition annular surface 703 is also beneficial for the metal material on the circular sheet base material to be accumulated and thickened toward the direction of the second extrusion protrusion 702, so that the processing efficiency of the thick rim 213 is higher.

[0030] Referring to FIG. 6, the circular sheet base material is finally processed to form the cookware 21. The cookware 21 includes a cookware bottom 211, a thin wall 212, and a thick rim 213.

[0031] The transition annular surface 703 is cone-shaped, the transition annular surface 703 and the first extrusion protrusion 701 are in smooth transition, and the transition annular surface 703 and the second extrusion protrusion 702 are in smooth transition.

[0032] When the pressure on the circular sheet base material from the first extrusion protrusion 701 is transitioned to the pressure from the transition annular surface 703, the pressure changes more uniformly. This avoids the formation of sharp parts between the first extrusion protrusion 701 and the transition annular surface 703, which could otherwise damage the surface of the circular sheet base material and affect the spinning effect. When the metal material on the circular sheet base material is extruded toward the corner between the transition annular surface 703 and the second extrusion protrusion 702, the arrangement mode in which the transition annular surface 703 and the second extrusion protrusion 702 are in smooth transition can effectively reduce the frictional force generated between the spinning wheel 7 and the circular sheet base material, so that the spinning wheel 7 can be used more smoothly.

[0033] The outer side wall of the first extrusion protrusion 701 is a right circular cylindrical surface.

[0034] When the first extrusion protrusion 701 extrudes the circular sheet base material, the contact area between the first extrusion protrusion 701 and the circular sheet base material is larger, and after the circular sheet base material is extruded by the first extrusion protrusion 701, the formed surface is smoother and more compact.

[0035] The outer side wall of the second extrusion protrusion 702 is a right circular cylindrical surface.

[0036] The outer side wall of the first extrusion protrusion 701 and the outer side wall of the second extrusion protrusion are coaxially arranged. After the circular sheet base material is subjected to spinning processing by the spinning wheel 7, the thickness of the formed thick rim 213 is more uniform. The strength of the structure along the extension of the thick rim 213 on the cookware 21 is more uniform.

[0037] A deflection angle formed between the surface of the transition annular surface 703 and the outer side wall of the first extrusion protrusion 701 is 40-50 degrees.

[0038] When the spinning wheel 7 performs the spinning processing, if the deflection angle is too small, the effect that the metal material in the circular sheet base material extruded is accumulated and thickened outside the transition annular surface 703 is insignificant, making it difficult to process the structure of the thick rim 213 of the cookware 21. If the deflection angle is too large, the extrusion force between the transition annular surface 703 and the circular sheet base material is too large, which is prone to cause an interrupted spinning process as the spinning wheel 7 cannot proceed. The deflection angle is set reasonably, so that the spinning wheel 7 considers both the processing and forming efficiency of the thick rim 213 and the smoothness of the working process.

[0039] Preferably, a deflection angle formed between the surface of the transition annular surface 703 and the outer side wall of the first extrusion protrusion 701 is 45 degrees.

[0040] A range of the first extrusion protrusion 701 extending in an axial direction of the spinning wheel 7 is a distance a, a range of the second extrusion protrusion 702 extending in the axial direction of the spinning wheel 7 is a distance b, and the distance a is less than the distance b.

[0041] The effect of accumulating and thickening the metal material of the circular sheet base material outside the second extrusion protrusion 702 and the effect of preventing edge warping of the circular sheet base material are further improved, facilitating use.
