Description

Technical Field

[0001] The present invention relates to a bar stock feeding device. Background Art

[0002] In order to achieve precise docking of bar stocks, currently, for each type of bar stock, a corresponding bar stock feeding mechanism is provided, resulting in a need to configure a relatively large number of bar stock feeding mechanisms and thus a high equipment purchase cost. In order to reduce the equipment purchase cost, some enterprises use one bar stock feeding mechanism for several types of bar stocks, but seamless docking of the heat treatment furnace cannot be achieved, and manual assistance is required, which cannot adapt to automated production and has low efficiency. Summary of the Invention

[0003] To solve the above problems, the present invention provides a bar stock feeding device, which includes a frame, and a guide chute, a positioning device, an adjusting device and a lifting device installed on the frame. The positioning device is installed on the lifting device, and the lifting device can drive the positioning device to move up and down between a loading position and a discharging position.

[0004] The positioning device includes at least two positioning plates. An upwardly open V-shaped groove is provided at the top of the positioning plate, and the V-shaped groove penetrates through two opposite sides of the positioning plate; the at least two positioning plates are arranged at intervals along an axial direction.

[0005] The guide chute includes a guide plate with an inclined upper surface, and the lower end of the upper surface of the guide plate extends towards the V-shaped groove of the positioning plate.

[0006] The adjusting device includes a rotating shaft rotatably installed on the frame. A material pushing rod is installed on the rotating shaft, and the material pushing rod is inserted between two adjacent positioning plates; when the rotating shaft is rotated, the material pushing rod rotates with the rotating shaft, so that a material groove with an upward opening is formed between the material pushing rod and the inner side wall of the V-shaped groove, and the size of the material groove changes with the rotation of the material pushing rod.

[0007] Viewed along the axial direction, each material groove forms a support groove for supporting the bar stock, and the support groove extends along the axial direction.

[0008] When the positioning device is at the loading position, the bar stock can roll along the guide plate and fall into the support groove; after the bar stock falls into the support groove, the lifting device can drive the positioning device to reach the discharging position.

[0009] The axial direction is parallel to the horizontal direction. Preferably, the included angle between the upper surface of the guide plate and the horizontal plane is 25-40°.

[0010] When the present invention is in use, first place the positioning device at the loading position, then rotate the rotating shaft according to the outer diameter of the bar stock to be transferred, so that the material pushing rod adjusts the size of the material groove until the formed support groove can only accommodate one bar stock to be transferred. Then fix the rotating shaft, and the bar stock falls from the guide plate into the support groove. Then start the lifting device, move the positioning device upward to the unloading position, and then unload the bar stock. After the bar stock is unloaded, move the positioning device downward to the loading position and continue to transfer the bar stock. Repeat this process until the transfer of the bar stock is completed. When the outer diameter of the bar stock to be transferred changes, reposition the material pushing rod according to the outer diameter of the new bar stock so that the formed support groove can only accommodate one new bar stock, and then transfer the new bar stock in the same way. With the present application, a single device can be used to complete the transfer of bar stocks with different outer diameters, avoiding the drawback of purchasing corresponding material separating devices for different bar stocks, thereby effectively reducing the corresponding equipment purchase cost.

[0011] To ensure that the bar stock can accurately fall into the support groove after rolling down from the guide plate, the thickness direction of each positioning plate is parallel to the axis direction; the central axis of the rotating shaft extends along this axis direction; the upper surface of the guide plate is parallel to this axis direction, and the inclination direction of the upper surface of the guide plate is perpendicular to this axis direction. Components such as the positioning plate, rotating shaft, and guide plate are positioned based on the axis direction, which can make the formed support groove basically parallel to the upper surface of the guide plate. During the process of the bar stock rolling downward from the guide plate, it will not deviate from the rolling direction and can smoothly roll into the support groove. The structure of the present application is simple, utilizes the gravity effect, and saves energy consumption.

[0012] For convenient operation, the guide plate and the rotating shaft are located on the same side of the positioning device. This design can make the equipment more compact, reduce the occupied space of the equipment, and the other side of the positioning device can be used as the working area for the operator.

[0013] To further reduce the occupied space of the equipment, in the height direction, the rotating shaft is located below the guide plate.

[0014] Furthermore, the lifting device includes a lifting frame and a lifting cylinder for driving the lifting frame to move up and down. The positioning plate is fixedly installed on the lifting frame, and the lifting cylinder is fixedly installed on the machine frame. Preferably, the lifting cylinder is a single-rod cylinder, the piston rod of the lifting cylinder extends in the vertical direction, and the lifting frame is fixed to the top of the piston rod; a guide rod is arranged vertically on the positioning plate, and a guiding part is arranged on the machine frame, and the guide rod can slide up and down along the guiding part.

[0015] By adopting a lifting cylinder, the operation can be simplified and the availability of the equipment can be improved. A guiding device formed by a guiding rod and a guiding part is provided, which can prevent the lifting device from deflecting during the up and down movement, causing the support groove to deviate from the original set position and resulting in unstable operation of the equipment. By using the lifting cylinder, the structure of the equipment is simplified and the operation is stable. The lifting stroke is fixed and no adjustment is required for tool change.

[0016] To facilitate the positioning of the rotating shaft, a limiting part is fixedly installed on the rotating shaft, and a limiting portion is provided on the limiting part. When the limiting part rotates with the rotating shaft to a set position, the limiting portion can be fixed on the machine frame by a fixing part. By using this limiting part, multi-variety positioning adjustment can be achieved.

[0017] Preferably, each V-shaped groove has two oppositely arranged inner side surfaces, which are respectively called the first inner side surface and the second inner side surface. The guide plate is located on one side of the positioning device and on the side where the first inner side surface is located; the connection line of the sides of all the material pushing rods facing the first inner side surface is located in a plane parallel to the axis direction; a material groove is formed between the material pushing rod and the first inner side surface. Further, the first inner side surfaces of all the V-shaped grooves are coplanar and parallel to the axis direction.

[0018] This design can ensure that there are no protruding points in the formed support groove. After the bar stock rolls into the support groove, it will not cause damage to the bar stock. At the same time, it can avoid the adverse impact on the subsequent work caused by the instability of the bar stock after rolling into the support groove due to the existence of protruding points. Radial precise positioning of the material can be achieved. Description of the Drawings

[0022] Refer to Figures 1-3 , in Figure 1 , the direction indicated by the arrow N shown at an appropriate position is the axis direction, and this axis direction is parallel to the horizontal direction. Figure 2 In

[0023] A bar stock feeding device, which includes a frame 80, and a material guiding slide plate 10, a positioning device 20, an adjusting device 30 and a lifting device 40 installed on the frame 80. For the sake of clear display, only a part of the structure of the frame is shown in each drawing.

[0024] The positioning device 20 includes several positioning plates 21, and the thickness direction of each positioning plate 21 is parallel to the axis direction. The positioning plates 21 are arranged at intervals along the axis direction. At the top of each positioning plate 21, there is an upward-opening V-shaped groove 211, and the V-shaped groove 211 penetrates through two opposite side surfaces of the positioning plate. The V-shaped groove 211 has two relatively arranged inner side surfaces, which are respectively called the first inner side surface 218 and the second inner side surface 219, and are parallel to the axis direction.

[0025] The material guiding slide plate 10 includes a material guiding plate 11, and the upper surface 111 of the material guiding plate 11 is inclined. The low end 115 of the upper surface of the material guiding plate 11 extends towards the V-shaped groove of the positioning plate 21, and the inclined direction of the upper surface of the material guiding plate 11 is perpendicular to the axis direction. In this embodiment, the included angle α between the upper surface 111 of the material guiding plate 11 and the horizontal plane is 35°. It can be understood that in other embodiments, according to different requirements, this included angle can also be 25°, 30° or 40°, and of course it can also be other angles between 25 - 40°.

[0026] The material guiding plate 11 is located on one side of the positioning device and on the side where the first inner side surface 218 is located. In this embodiment, all the first inner side surfaces 218 are coplanar.

[0027] The adjusting device 30 includes a rotating shaft 33, and the central axis of the rotating shaft 33 extends along the axis direction. Both ends of the rotating shaft 33 are installed on the frame 80 through bearing seats 331, and the rotating shaft 33 rotates freely. The rotating shaft is located below the material guiding plate 11 and on the same side of the positioning device 20 as the material guiding plate 11. A material pushing rod 35 is installed on the rotating shaft 33, and the material pushing rod 35 is inserted between two adjacent positioning plates. The connecting lines of all the material pushing rods on the side facing the first inner side surface 218 form a plane parallel to the axis direction.

[0028] When the rotating shaft 33 is rotated and the material pushing rod 35 rotates with the rotating shaft, a material trough 100 with an upward opening is formed between the material pushing rod and the first inner side wall 218 of the V-shaped groove. The size of the material trough 100 changes with the rotation of the material pushing rod to adapt to bar stocks 50 with different outer diameters. When observing along the axis direction, each material trough forms a supporting trough for supporting the bar stock, and the supporting trough extends along the axis direction. The bar stock can roll along the material guiding plate and fall into the supporting trough.

[0029] To prevent the bar stock from falling off from one side of the stock guide plate 11, in this embodiment, along the axial direction, a stock stop plate 13 is provided on each side of the stock guide plate 11. The end of the stock stop plate 13 away from the positioning device is bent outward to form a flared portion 14, so as to facilitate the bar stock to roll smoothly downward along the stock guide plate 11.

[0030] The lifting device 40 includes a lifting frame 42 and a lifting cylinder 41 for driving the lifting frame 42 to move up and down. The positioning plate 21 is fixedly installed on the lifting frame. The lifting frame 24 includes a support plate 46 extending along the axial direction, and the support plate extends in the vertical direction. A card slot 43 is formed at the top of the support plate 46, and a positioning plate 21 is fixedly installed in each card slot 43. A guide rod 45 is provided on the lower side of the support plate 46, a guiding portion 44 is installed on the frame 80, and a guiding hole is formed in the guiding portion 44 in the vertical direction. In this embodiment, the guide rod is cylindrical, the guide rod 45 extends in the vertical direction, the upper end of the guide rod is fixed to the lower side of the support plate, and the lower end of the guide rod penetrates downward through the guiding hole and is fixed to the frame. The guide rod can slide up and down along the guiding hole, that is, the guide rod can slide up and down along the guiding portion.

[0031] It can be understood that in other embodiments, the guide rod can also be a groove block with a card slot, and the guiding portion is a guide rail, and the groove block slides up and down along the guide rail through the card slot. Of course, the guide rod can also be a guide rail, and the guiding portion is called a groove block.

[0032] In this embodiment, the lifting cylinder 41 is a single-rod cylinder, which is fixedly installed on the frame 80. The piston rod 411 of the lifting cylinder supports on the bottom of the lifting frame 42. Under the limitation of the guide rod, the piston rod of the lifting cylinder can push the lifting frame 42 to move in the vertical direction, so as to drive the positioning device 20 to move up and down between the loading position and the unloading position. When the positioning device 20 is at the loading position, the bar stock can roll along the stock guide plate and fall into the support groove; after the bar stock falls into the support groove, the lifting device drives the positioning device to move upward to the unloading position. At the unloading position, the bar stock is fed into the next process. After the bar stock is fed into the next process, the lifting device drives the positioning device to move downward to the unloading position and carry the bar stock again.

[0033] To better locate the position of the stock pushing rod, in this embodiment, a limiting member 31 is fixedly installed at one end of the rotating shaft. The opposite ends of the limiting member are respectively formed into a mounting end 312 and a limiting end 313, wherein the mounting end is fixedly installed at one end of the rotating shaft 33. An arc groove 311 is formed in the limiting end 313, and the arc groove 311 penetrates through the limiting end. The arc groove is centered on the central axis of the rotating shaft. After rotating the rotating shaft to make the stock pushing rod rotate to the set position, the limiting end 313 is fixed to the frame through the arc groove by using a locking bolt. In the drawings, the locking bolt is not shown, and the locking bolt is formed as a fixing member. The arc groove is formed as a limiting portion.

[0034] According to the different outer diameters of the bar stock, rotate the limiting member to drive the rotating shaft to drive the stock pushing rod to rotate to the corresponding set position, so that the formed support groove can only accommodate one bar stock, and then fix the limiting member to fix the size of the support groove, so that the transfer of different bar stocks can be completed by using this embodiment.
