Description

Technical Field

[0001] The utility model relates to the technical field of production of copper sheets for valve seats, and particularly relates to a feeding device for copper sheets for valve seats and a production line for valve seats. Background Art

[0002] The part on the cylinder head that fits with the valve cone surface is called the valve seat. The temperature of the valve seat is very high, and it also bears an extremely high-frequency impact load, making it prone to wear. Therefore, aluminum cylinder heads and most cast iron cylinder heads are inlaid with valve seats made of alloy cast iron, powder metallurgy, or austenitic steel. Inlaying valve seats in the cylinder head can extend the service life of the cylinder head. However, the thermal conductivity of ordinary valve seats is not ideal, and the interference fit with the cylinder hole needs to be properly selected. Otherwise, the seat ring will fall off during operation. Therefore, the valve seat needs to be appropriately improved. Furthermore, the valve seat needs to be stacked and sintered with copper sheets, with each copper sheet corresponding to one seat ring. During the sintering process, the copper sheet will penetrate into the pores of the seat ring, thereby improving the strength and thermal conductivity of the seat ring.

[0003] However, currently, the copper sheets formed by pressing are usually manually fed, and then placed in the next station for stacking and sintering. The speed of manual feeding is low, seriously affecting the production efficiency of copper sheets and the production efficiency of copper sheets for valve seats. Moreover, manual feeding is prone to material leakage, resulting in waste of copper sheets. Summary of the Utility Model

[0004] In order to solve the problems of low efficiency and low automation degree in manually feeding copper sheets and placing them in the next station for sintering, the utility model provides a feeding device for copper sheets for valve seats and a production line for valve seats. The specific technical solutions are as follows:

[0005] The utility model includes a feeding device body for sorting copper sheets for valve seats. The feeding device body includes: a limiting member, which forms a limiting groove capable of restricting the movement of copper sheets for valve seats. The limiting groove can realize automatic centering of copper sheets for valve seats; a moving support member arranged on the bottom surface of the limiting groove, which moves along the central plane of the limiting groove. The bottom surface of the limiting groove and the moving support member jointly enclose a feeding cavity. When the moving support member moves away from the limiting groove along the central plane of the limiting groove, the feeding cavity can form a passage allowing copper sheets for valve seats to pass through.

[0006] Furthermore, the limiting groove forms a structure with an included angle, and the maximum of the included angle is an obtuse angle. The structure is symmetric about the central plane, and the included angle of the structure is opposite to the feeding direction of the copper sheets for valve seats.

[0007] Furthermore, the limiting member further includes a limiting surface that is continuously connected to form a limiting groove. The limiting surface is perpendicular to the moving support member. When the material receiving cavity is surrounded by two limiting surfaces and the moving support member, the limiting surfaces intersect to form a V-shaped limiting groove that is symmetric about the central plane. The opening side formed by the limiting surfaces faces the feeding direction of the valve seat ring copper sheet.

[0008] Furthermore, the limiting member further includes a limiting surface that is continuously connected to form a limiting groove. The limiting surface is perpendicular to the moving support member. When the material receiving cavity is surrounded by three or more limiting surfaces and the moving support member, the limiting surfaces form an irregular limiting groove with an included angle that is symmetric about the central plane. The distance between at least a part of the opening sides formed by the limiting surfaces is less than the diameter of the valve seat ring copper sheet, and at least a part is greater than the diameter of the valve seat ring copper sheet.

[0009] Preferably, the bottom surface of the limiting groove, the bottom surface of the material receiving cavity, and the top surface of the moving support member coincide.

[0010] Preferably, the moving support member includes: a cylinder whose telescopic direction is parallel to the central plane of the limiting groove; and a support plate that contacts the bottom surface of the limiting groove. The telescopic end of the cylinder drives the support plate to move along the middle plane of the limiting groove. The top surface of the support plate is the top surface of the moving support member, and the top surface of the support plate moves as the cylinder moves. The bottom surface of the material receiving cavity moves as the cylinder moves.

[0011] Preferably, the material receiving device body further includes a sensor for detecting whether there is a valve seat ring copper sheet in the limiting groove and a material receiving rod for storing the valve seat ring copper sheet. The axis of the material receiving rod is perpendicular to the moving support member, and the material receiving rod can catch the valve seat ring copper sheet that falls from the channel formed by the material receiving cavity.

[0012] The present utility model further includes a valve seat ring production line, which includes: a production line, the production line includes a mounting bracket and an inclined chute, and the valve seat ring copper sheet enters the material receiving cavity along the inclined chute; and a material receiving device arranged on the mounting bracket.

[0013] Furthermore, the inclined chute is an inclined surface with a slope. The slope of the inclined chute enables the valve seat ring copper sheet to slide and also to fit without separating from the inclined chute.

[0014] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects:

[0015] The utility model forms a limiting groove with an opening side by arranging limiting surfaces symmetrical about the central plane, enabling the side surface of the valve seat ring copper sheet to be tangent to the limiting surface. Thus, after the valve seat ring copper sheet falls into the limiting groove, automatic centering can be achieved, and the axes of valve seat rings of different sizes are all coincident with the middle plane. When the sensor controls the cylinder to push the support plate to make the valve seat ring copper sheet fall, by adjusting the position of the limiting groove, the axes of valve seat ring copper sheets of different sizes can be made to coincide with the axis of the receiving rod, enabling the receiving rod to catch the falling valve seat ring copper sheet, thereby improving the automation degree and receiving accuracy of the receiving device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0021] Embodiment 1

[0022] As Figure 1As shown in the figure, the embodiment of the utility model includes a material receiving device body 1 for sorting copper sheets of valve seats. The material receiving device body 1 includes: a limiting member 11, which forms a limiting groove 111 capable of restricting the movement of the copper sheets of valve seats. The limiting groove 111 can realize the automatic centering of the copper sheets of valve seats; a moving support member 12 arranged on the bottom surface of the limiting groove 111. The moving support member 12 moves along the central plane of the limiting groove 111. The bottom surface of the limiting groove 111 and the moving support member 12 jointly enclose a material receiving cavity 15. When the moving support member 12 moves away from the limiting groove 111 along the central plane of the limiting groove 111, the material receiving cavity 15 can form a passage allowing the copper sheets of valve seats to pass through.

[0023] Specifically, the copper sheets of valve seats are in a circular ring shape. According to geometric knowledge, when there are two intersecting planes that are both tangent to the side surface of the circular ring, the symmetry plane of the two planes coincides with the axis of the circular ring. Therefore, at least two intersecting planes of the limiting groove 111 are tangent to the side surface of the copper sheets of valve seats, so that the automatic centering can be realized when the copper sheets of valve seats contact the limiting groove 111, that is, the axis of the copper sheets of valve seats coincides with the symmetry plane of the limiting groove 111.

[0024] Secondly, the limiting groove 111 is formed by at least two planes, and its bottom surface is a plane perpendicular to the two side surfaces at the same time. Therefore, when the moving support member 12 is connected to the bottom surface of the limiting groove 111, the connecting surface between the moving support member 12 and it and the side surface of the limiting groove 111 jointly enclose a material receiving cavity 15 composed of at least three planes. The top surface of the moving support member 12 serves as the bottom surface of the material receiving cavity 15, so that when the moving support member 12 moves along the central plane of the limiting groove 111, the bottom surface of the material receiving cavity 15 also moves relative to the central plane of the limiting groove 111, so that the moving support member 12 does not intersect with the two side surfaces of the limiting groove 111, and further the copper sheets of valve seats placed on the bottom surface of the material receiving cavity 15 lose support and fall to the next working station from the formed passage, thereby realizing mechanical material receiving of the copper sheets of valve seats, improving the material receiving efficiency, and avoiding the waste of raw materials caused by human errors. When it is detected whether the valve seat is in the material receiving cavity 15 through the sensor 13 and then the movement of the moving support member 12 is controlled, the automatic material receiving of the copper sheets of valve seats can be realized.

[0025] Furthermore, the limiting groove 111 forms a centering mechanism with an included angle. The centering mechanism is symmetric about the central plane, and the opening side formed by the centering mechanism faces the copper sheets of valve seats.

[0026] Specifically, the limiting groove 111 is composed of at least two intersecting faces, and both of these two faces are tangent to the copper sheet of the valve seat ring, so that there must be an included angle in the limiting groove 111. The opening side of the included angle faces the feeding direction of the copper sheet of the valve seat ring, so that the copper sheet of the valve seat ring moves towards the opening side of the included angle, so that the included angle can limit the position of the copper sheet of the valve seat ring and achieve automatic centering; secondly, the smaller the angle of the included angle, the larger the size of the limiting groove 111 is required to be tangent to the side surface of the copper sheet of the valve seat ring. Therefore, the value of the included angle is adjusted according to the diameter of the copper sheet of the valve seat ring; secondly, the relative position of the included angle and the feeding direction of the copper sheet of the valve seat ring enables the two faces of the included angle to exert a supporting force on the copper sheet of the valve seat ring, and the supporting forces intersect at the axis of the copper sheet of the valve seat ring, so that the limiting groove 111 can limit the position of the copper sheet of the valve seat ring and achieve automatic centering at the same time, simplify the feeding structure, and improve the feeding efficiency.

[0027] Further, the limiting member 11 further includes a limiting surface 112 that is continuously connected to form the limiting groove 111. The limiting surface 112 is perpendicular to the moving support member 12. When the receiving cavity 15 is surrounded by two limiting surfaces 112 and the moving support member 12, the limiting surfaces 112 intersect to form a V-shaped limiting groove that is symmetric about the central plane, and the opening side formed by the limiting surfaces 112 is opposite to the feeding direction of the copper sheet of the valve seat ring.

[0028] Or when the receiving cavity 15 is surrounded by three or more limiting surfaces 112 and the moving support member 12, the limiting surfaces 112 form an irregular limiting groove 111 with an included angle that is symmetric about the central plane. The distance between at least a part of the opening sides formed by the limiting surfaces 112 is less than the diameter of the copper sheet of the valve seat ring, and at least a part is greater than the diameter of the copper sheet of the valve seat ring.

[0029] Specifically, there are two embodiments of the limiting groove 111. The first embodiment of the limiting groove 111:

[0030] The limiting groove 111 is composed of two intersecting limiting surfaces 112 that are tangent to the side surface of the copper sheet of the valve seat ring, forming a V-shaped limiting groove. The two limiting surfaces 112 naturally form an included angle, so that after the copper sheet of the valve seat ring enters the opening side formed by the two limiting surfaces 112 from the feeding direction, it can be restricted from continuing to move and the axis of the copper sheet of the valve seat ring coincides with the central plane of the two limiting surfaces 112, realizing automatic centering; secondly, during the conveying process of the copper sheet of the valve seat ring, its side surface is naturally perpendicular to the conveying surface, that is, perpendicular to the moving support member 12. When the limiting surface 112 is perpendicular to the moving support member 12, the side surface of the copper sheet of the valve seat ring is parallel to the limiting surface 112, so that the limiting surface 112 can be in complete contact with the side surface of the copper sheet of the valve seat ring, and further the axes of valve seat rings of different sizes coincide with the central plane of the limiting groove 111.

[0031] The second embodiment of the limiting groove 111:

[0032] The limiting groove 111 is composed of three or more continuously intersecting limiting surfaces 112 to form an irregular limiting groove. At least two limiting surfaces 112 are tangent to the side surface of the copper sheet of the valve seat ring, and the tangent limiting surfaces 112 are symmetric about the central plane of the limiting groove 111. The diameter of the copper sheet of the valve seat ring is between the distances of the opening side formed by the limiting groove 111, so that the limiting groove 111 can limit the copper sheet of the valve seat ring and realize its automatic centering. And when the included angle in the second embodiment is the same as that in the first embodiment, the size of the limiting groove 111 in the second embodiment is smaller, which can further reduce the size of the overall device.

[0033] Furthermore, the bottom surface of the limiting groove 111, the bottom surface of the material receiving cavity 15, and the top surface of the moving support 12 coincide.

[0034] Specifically, the top surface of the moving support 12 slides relative to the bottom surface of the limiting groove 111. When the moving support 12 intersects with the side surface of the limiting groove 111, the top surface of the moving support 12 becomes the bottom surface of the material receiving cavity 15, so that the top surface of the moving support 12 and the side surface of the limiting groove 111 can jointly form the material receiving cavity 15. Furthermore, whether the material receiving cavity 15 can provide a supporting force for the copper sheet of the valve seat ring depends on whether the moving support 12 intersects with the side surface of the limiting groove 111.

[0035] Furthermore, the moving support 12 includes: a cylinder 121 whose telescopic direction is parallel to the central plane of the limiting groove 111; and a support plate 122 in contact with the bottom surface of the limiting groove 111. The telescopic end of the cylinder 121 drives the support plate 122 to move along the middle plane of the limiting groove 111. The top surface of the support plate 122 is the top surface of the moving support 12, and the top surface of the support plate 122 moves with the movement of the cylinder 121, and the bottom surface of the material receiving cavity 15 moves with the movement of the cylinder 121.

[0036] Specifically, the top surface of the support plate 122 is the bottom surface of the material receiving cavity 15, and the telescopic end of the cylinder 121 is fixedly connected to the support plate 122. When the cylinder 121 slides along the central plane of the limiting groove 111, the top surface of the support plate 122 can slide relative to the bottom surface of the limiting groove 111. Furthermore, the bottom surface of the material receiving cavity 15 slides relative to the bottom surface of the limiting groove 111. Furthermore, sometimes the material receiving cavity 15 can form a channel allowing the copper sheet of the valve seat ring to fall, so that the axis of the copper sheet of the valve seat ring is fixed and enters the next working station from a certain position.

[0037] Furthermore, the material receiving device body 1 further includes a sensor 13 for detecting whether there is a copper sheet of the valve seat ring in the limiting groove 111 and a material receiving rod 14 for storing the copper sheet of the valve seat ring. The axis of the material receiving rod 14 is perpendicular to the moving support 12, and the material receiving rod 14 can catch the copper sheet of the valve seat ring falling from the channel formed by the material receiving cavity 15.

[0038] Specifically, when the copper valve seat insert is restricted in position by the limiting groove 111, the sensor 13 receives a signal, and then controls the cylinder 121 to drive the support plate 122 away from the limiting groove 111, so that the overlapping part between the bottom surface of the material receiving cavity 15 and the copper valve seat insert gradually decreases, and then the copper valve seat insert can fall from the material receiving cavity 15. Therefore, it falls after being tangent to the side surface of the limiting groove 111. Thus, copper valve seat inserts of the same size fall at the same position. For copper valve seat inserts of different sizes, only by adjusting the position of the limiting groove 111 relative to the material receiving rod 14 can the axis during the falling process of the copper valve seat insert coincide with the axis of the material receiving rod 14, thereby realizing the automatic sorting action of the copper valve seat inserts and improving the material receiving speed of the copper valve seat inserts.

[0039] Embodiment 2

[0040] As Figure 2 shown, Embodiment 2 includes: a production line, which includes a mounting bracket 21 and an inclined chute 22, and the copper valve seat insert enters the material receiving cavity 15 along the inclined chute 22; and the material receiving device of Embodiment 1 provided on the mounting bracket 21.

[0041] Specifically, the inclined chute 22 has a slope so that the copper valve seat insert can slide along its surface under the action of gravity, and then enter and be tangent to the limiting groove 111, and then fall into the material receiving rod 14 for the next process; both the material receiving device and the inclined chute 22 are connected to the mounting bracket 21 by bolts, so that the relative position between the two remains unchanged, and the copper valve seat insert can always slide into the limiting groove 111 for automatic centering.

[0042] Furthermore, the inclined chute 22 is an inclined surface with a slope, and the slope of the inclined chute 22 enables the copper valve seat insert to slide and also adhere to it without separating from the inclined chute 22.

[0043] Specifically, the copper valve seat insert slides along the inclined chute 22. When the slope of the inclined chute 22 is small, the copper valve seat insert remains stationary under the action of the frictional force exerted by the inclined chute 22, and the production line cannot operate. When the slope of the inclined chute 22 is too large, the copper valve seat insert is prone to jumping during the sliding process, causing its surface to separate from the inclined chute 22, which may result in the copper valve seat insert not necessarily being able to slide into the limiting groove 111, and it will also scratch the copper valve seat insert and affect its surface quality.

[0044] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
