Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically to a feeding device for sawing bar stock. Background Technology

[0002] When machining ring forgings, metal bars need to be sawn into segments of the required length, and then these segments are subjected to heating, forging, heat treatment, and turning processes in sequence. A band saw is required for sawing the bars. A feeding device is needed when feeding the band saw.

[0003] A search revealed that patent CN216263857U discloses "A Lifting and Feeding Device and a Sawing Mechanism." See also... Figure 1 The patent includes a loading seat and a lifting assembly 1. The loading seat includes a feeding section 2 and a sawing section 3. The top surface of the feeding section 2 is a feeding surface 21, which is inclined toward the sawing section 3. A stop seat 4 is provided at one end of the feeding surface 21 near the sawing section 3. Due to the inclined setting of the feeding surface 21, the bar stock to be sawed will continuously roll downwards until it is blocked by the stop seat 4. The lifting assembly 1 is used to lift the bar stock abutting against the side of the stop seat 4 and transport it to the sawing section 3. When it reaches the sawing position, the lifting assembly 1 falls back for the band saw to cut.

[0004] In the aforementioned patent, the length of the feeding section limits the storage capacity of the bar stock, making it inconvenient to store more bars. Therefore, how to increase the storage space for bar stock is a technical problem that needs to be solved. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention proposes a feeding device for bar sawing. This invention increases the storage space for bars, thereby increasing the storage capacity and improving storage flexibility.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A feeding device for bar sawing includes a feeding seat, a lifting assembly, and a storage rack. The feeding seat includes a feeding section and a sawing section. The top surface of the feeding section is a feeding surface, which is inclined to the sawing section. A stop seat is provided at one end of the feeding surface near the sawing section. The storage rack is straddling the feeding section. A first inclined frame and a second inclined frame are provided on the storage rack. A first discharge port is provided at the lower end of the first inclined frame, which is located above the end of the feeding surface away from the stop seat. A second discharge port is provided at the lower end of the second inclined frame, which is located above the upper end of the first inclined frame.

[0008] Furthermore, the storage rack includes a first gantry frame, a second gantry frame, a first limiting frame, and a second limiting frame. The first gantry frame spans above the end of the feeding section near the sawing section, and the second gantry frame spans above the end of the feeding section away from the sawing section. The upper end of the first tilting frame is connected to the upper end of the first gantry frame, and the lower end of the first tilting frame is provided with the first discharge port between it and the second gantry frame. The upper end of the first tilting frame is provided with the first limiting frame, and the upper end of the second tilting frame is connected to the upper end of the second gantry frame. The lower end of the second tilting frame is provided with the second discharge port between it and the first limiting frame, and the upper end of the second tilting frame is provided with the second limiting frame.

[0009] Furthermore, the storage rack also includes a first support frame and a second support frame, both of which are straddling the middle of the feeding section. The top of the first support frame is connected to the bottom of the first inclined frame, and the top of the second support frame is connected to the bottom of the second inclined frame.

[0010] Furthermore, the feeding seat includes two feeding tracks, each including a feeding section and a sawing section. The lifting assembly includes a moving module, a lifting module, and a transmission module. The moving module is located between the two feeding tracks and is used to move between the feeding section and the sawing section. The moving module is equipped with a lifting module, which is used to drive the transmission module to lift and lower. The transmission module is used to transmit the bar stock along its axial direction.

[0011] Furthermore, the moving module includes a guide rail, a rack, a moving seat, a moving motor, and a gear. The two feeding tracks are each provided with a guide rail and a rack on the side facing each other. The moving seat is slidably engaged with the guide rail. The moving seat is provided with a moving motor. The output end of the moving motor is provided with a gear, which meshes with the rack.

[0012] Furthermore, the lifting module includes a lifting rod and a lifting plate, the lifting rod is mounted on the movable seat, and the upper end of the lifting rod is provided with a lifting plate.

[0013] Furthermore, the transmission module includes a transmission seat, a transmission roller, a pulley, a belt, and a transmission motor. The top surface of the lifting plate is provided with multiple transmission seats, and two symmetrically arranged support plates are provided on the transmission seats. A transmission roller is provided between the two support plates. The roller shaft of the transmission roller is rotatably connected to the support plate. A pulley is provided on the roller shaft of the transmission roller. The pulleys on each pair of adjacent transmission rollers are driven by a belt. The transmission motor is located on the lifting plate, and the output end of the transmission motor is connected to the roller shaft of one transmission roller.

[0014] The beneficial effects of this utility model are:

[0015] 1. Because this utility model is equipped with a storage rack, and a first inclined rack and a second inclined rack are provided on the storage rack, the first inclined rack and the second inclined rack can also be used to store the bar material to be sawed in addition to using the feeding section to store the bar material to be sawed. Compared with the prior art, this utility model increases the space for storing bar material, which is conducive to increasing the storage capacity of bar material and improving storage flexibility.

[0016] 2. Because the feeding section, the first inclined frame, and the second inclined frame are arranged sequentially from bottom to top, the vertical space can be fully utilized when storing bar stock to be sawed, without having to extend the length of the feeding section, thus improving space utilization.

[0017] 3. Because the lower end of the first inclined frame is provided with a first discharge port, which is located above the end of the feeding section away from the stop seat, and the lower end of the second inclined frame is provided with a second discharge port, which is located above the upper end of the first inclined frame, whenever a bar is taken from the feeding section, the bar on the first inclined frame will be replenished to the feeding section, and the bar on the second inclined frame will be replenished to the first inclined frame. This realizes automatic replenishment of bar, eliminating the need for manual replenishment and saving manpower.

[0018] 4. The support of the first support frame improves the stability and reliability of the first inclined frame in carrying the bar stock; the support of the second support frame improves the stability and reliability of the second inclined frame in carrying the bar stock. This, in turn, enhances the safety and reliability of the storage rack for bar stock.

[0019] 5. By setting up a transmission module, the bar stock can be transmitted along the axial direction after it is transmitted to the sawing section, so that the bar stock can be smoothly transmitted to the band saw located in front of the sawing section, thus improving adaptability.

[0046] Example 1:

[0047] A feeding device for bar sawing includes a feeding seat, a lifting assembly, and a storage rack.

[0048] See Figure 2 The feeding seat includes a feeding section 2 and a sawing section 3. The top surface of the feeding section 2 is a feeding surface 21, which is inclined toward the sawing section 3. A stop seat 4 is fixedly installed on one end of the feeding surface 21 near the sawing section 3. Due to the inclined setting of the feeding surface 21, the bar material 5 to be sawed will roll downwards continuously until it is blocked by the stop seat 4.

[0049] See Figure 2 The lifting assembly is used to lift the bar stock 5 that is against the side of the stop 4 and transport it to the sawing section 3.

[0050] See Figure 2 and Figure 3 The storage rack is spanned above the feeding section 2. A first tilting frame 7 and a second tilting frame 8 are fixedly installed on the storage rack. The lower end of the first tilting frame 7 is provided with a first discharge port 71, which is located above the end of the feeding surface 21 away from the baffle seat 4. The lower end of the second tilting frame 8 is provided with a second discharge port 81, which is located above the upper end of the first tilting frame 7.

[0051] The working principle of this embodiment 1 is as follows:

[0052] See Figure 6 The feeding section 2, the first tilting frame 7, and the second tilting frame 8 can all be used to support the bar stock 5 to be sawed. The bar stock 5 at the leftmost end of the feeding section 2 abuts against the right side wall of the stop seat 4, and the bar stock 5 at the rightmost end of the feeding section 2 is located below the first discharge port 71. The bar stock 5 in the first discharge port 71 falls onto the bar stock 5 at the rightmost end of the feeding section 2. The bar stock 5 at the rightmost end of the first tilting frame 7 abuts against the bar stock 5 located in the first discharge port 71, and the bar stock 5 at the leftmost end of the first tilting frame 7 is located below the second discharge port 81. The bar stock 5 in the second discharge port 81 falls onto the bar stock 5 at the leftmost end of the first tilting frame 7. The bar stock 5 at the leftmost end of the second tilting frame 8 abuts against the bar stock 5 located in the second discharge port 81.

[0053] When the bar stock 5, which is abutting the right side wall of the stop seat 4, is moved to the sawing section 3 by the lifting assembly, the bar stock 5 on the feeding section 2 rolls down along the inclined feeding surface 21 until the next bar stock 5 is blocked by the stop seat 4. When the bar stock 5 on the feeding section 2 rolls toward the stop seat 4, a new empty space is created at the rightmost end of the feeding section 2. The bar stock 5 that was originally located in the first discharge port 71 falls into the empty space at the rightmost end of the feeding section 2. The bar stock 5 on the first tilting frame 7 rolls toward the first discharge port 71, and the bar stock 5 that was originally at the rightmost end of the first tilting frame 7 falls into the first discharge port 71, creating a new empty space at the leftmost end of the first tilting frame 7. The bar stock 5 that was originally located in the second discharge port 81 falls into the empty space at the leftmost end of the first tilting frame 7. The bar stock 5 on the second tilting frame 8 rolls toward the second discharge port 81, and the bar stock 5 that was originally at the rightmost end of the second tilting frame 8 falls into the second discharge port 81, thus filling the gap.

[0054] In summary, whenever a bar stock 5 is removed from the feeding section 2, the bar stock 5 on the first tilting frame 7 will be replenished to the feeding section 2, and the bar stock 5 on the second tilting frame 8 will be replenished to the first tilting frame 7, thus realizing automatic replenishment of the bar stock 5 without the need for manual replenishment, which helps to save manpower.

[0055] In addition, when it is necessary to replenish the bar stock 5 on the storage rack, the bar stock 5 can be placed on the second inclined frame 8 using a gantry crane.

[0056] Based on the working principle described above in Embodiment 1, it can be seen that Embodiment 1 has the following effects:

[0057] First, because this embodiment 1 is equipped with a storage rack, and a first tilting rack 7 and a second tilting rack 8 are provided on the storage rack, in addition to using the feeding section 2 to store the bar stock 5 to be sawed, the first tilting rack 7 and the second tilting rack 8 can also be used to store the bar stock 5 to be sawed. Compared with the prior art, this embodiment 1 increases the space for storing the bar stock 5, which is beneficial to increasing the storage capacity of the bar stock 5 and improving storage flexibility.

[0058] Secondly, since the feeding section 2, the first inclined frame 7, and the second inclined frame 8 are arranged sequentially from bottom to top, the vertical space can be fully utilized when storing the bar material 5 to be sawed, without having to extend the length of the feeding section 2, thus improving space utilization.

[0059] Example 2:

[0060] This embodiment 2 provides a specific structure for the storage rack in embodiment 1:

[0061] See Figure 2 and Figure 3The storage rack includes a first gantry frame 61, a second gantry frame 62, a first limiting frame 63, a second limiting frame 64, a first support frame 65, and a second support frame 66.

[0062] See Figure 4 , Figure 8 and Figure 9 The first gantry 61 is straddling above the end of the feeding section 2 near the sawing section 3. The width of the first gantry 61 is greater than the length of the bar stock 5, which can prevent the first gantry 61 from blocking the bar stock 5 located on the feeding section 2, so that the bar stock 5 on the feeding section 2 can roll smoothly to the stop seat 4.

[0063] See Figure 3 and Figure 7 The second gantry 62 is positioned above the end of the feeding section 2 that is away from the sawing section 3. The width of the second gantry 62 is less than the length of the bar stock 5, so that the bar stock 5 can be limited and blocked by the second gantry 62 to prevent the bar stock 5 from falling from the end of the feeding section 2 that is away from the sawing section 3.

[0064] See Figure 2 , Figure 3 and Figure 4 The upper end of the first tilting frame 7 is fixedly installed on the upper end of the first gantry frame 61. A first discharge port 71 is provided between the lower end of the first tilting frame 7 and the second gantry frame 62. The first discharge port 71 is located above the end of the feeding surface 21 furthest from the stop seat 4. A first limiting frame 63 is fixedly installed on the upper end of the first tilting frame 7. (See also...) Figure 6 , Figure 7 and Figure 8 The bar stock 5 located on the first inclined frame 7 can roll down to the feeding section 2 through the first discharge port 71, and the first limiting frame 63 can prevent the bar stock 5 located on the first inclined frame 7 from falling from the top of the first inclined frame 7.

[0065] See Figure 2 , Figure 3 and Figure 4 The upper end of the second inclined frame 8 is fixedly installed on the upper end of the second gantry frame 62. A second discharge port 81 is provided between the lower end of the second inclined frame 8 and the first limiting frame 63. The second discharge port 81 is located above the upper end of the first inclined frame 7. A second limiting frame 64 is fixedly installed on the upper end of the second inclined frame 8. See also Figure 6 , Figure 7 and Figure 8 The bar stock 5 located on the second inclined frame 8 can roll down to the first inclined frame 7 through the second discharge port 81. The second limiting frame 64 can prevent the bar stock 5 located on the second inclined frame 8 from falling from the upper end of the second inclined frame 8.

[0066] See Figure 2 and Figure 3The first support frame 65 and the second support frame 66 are both positioned above the middle of the feeding section 2. The width of both the first support frame 65 and the second support frame 66 is greater than the length of the bar stock 5, so they do not obstruct the transmission of the bar stock 5. The top of the first support frame 65 abuts against the bottom surface of the first inclined frame 7, thereby improving the stability and reliability of the first inclined frame 7 in carrying the bar stock 5. The top of the second support frame 66 abuts against the bottom surface of the second inclined frame 8, thereby improving the stability and reliability of the second inclined frame 8 in carrying the bar stock 5. This improves the safety and reliability of the storage rack for the bar stock 5.

[0067] Example 3:

[0068] This embodiment 3 provides a specific structure of the feeding seat and lifting assembly from embodiment 1.

[0069] See Figure 3 and Figure 4 The feeding seat includes two parallel feeding tracks, each of which includes a feeding section 2 and a sawing section 3.

[0070] The material lifting assembly includes a moving module, a lifting module, and a conveying module.

[0071] See Figure 4 and Figure 9 The moving module is located between two feeding tracks. The moving module includes a guide rail 111, a rack 112, a moving base 113, a moving motor 114, and a gear 115. The guide rail 111 and the rack 112 are fixedly installed on the side of each feeding track facing each other. The moving base 113 is slidably engaged with the guide rail 111. The moving motor 114 is fixedly installed on the moving base 113. The output end of the moving motor 114 is fixedly installed with a gear 115, which meshes with the rack 112.

[0072] See Figure 9 The lifting module includes a lifting rod 121 and a lifting plate 122. The lifting rod 121 can be a hydraulic cylinder or a pneumatic cylinder. The lifting rod 121 is fixedly installed on both moving seats 113. The upper ends of the two lifting rods 121 are jointly installed with a lifting plate 122.

[0073] See Figure 5The transmission module includes a transmission base 131, a transmission roller 132, a pulley 133, a belt 134, and a transmission motor 135. Five transmission bases 131 are fixedly installed on the top surface of the lifting plate 122. Two symmetrically arranged support plates 1311 are fixedly installed on the transmission bases 131. A transmission roller 132 is provided between the two support plates 1311. The roller shaft of the transmission roller 132 is rotatably connected to the support plate 1311. A pulley 133 is fixedly installed on the roller shaft of the transmission roller 132. The pulleys 133 on each pair of adjacent transmission rollers 132 are driven by the belt 134. The transmission motor 135 is fixedly installed on the lifting plate 122, and the output end of the transmission motor 135 is fixedly connected to the roller shaft of one transmission roller 132.

[0074] See Figure 11 and Figure 12 , Figure 10 The band saw 9 shown is placed in front of the sawing section 3.

[0075] The working principle of the material lifting assembly in this embodiment 3 is as follows:

[0076] The initial state of the lifting assembly is as follows: the moving seat 113 is located at the end of the feeding section 2 near the stop seat 4, and the support plate 1311 on the transmission seat 131 is located below the bar stock 5. When feeding is required:

[0077] (1) The lifting rod 121 drives the lifting plate 122 to rise. When the lifting plate 122 is higher than the stop seat 4, the lifting of the lifting plate 122 can be stopped. During the lifting process of the lifting plate 122, the lifting plate 122 drives the transmission seat 131 to move upward. The two support plates 1311 on the transmission seat 131 support the bar material 5 that is currently abutting against the side of the stop seat 4. The transmission roller 132 on the transmission seat 131 contacts the bottom of the bar material 5.

[0078] (2) The moving motor 114 drives the gear 115 to rotate forward. The gear 115 drives the moving seat 113 to move from the feeding section 2 to the sawing section 3. The moving seat 113 drives the bar material 5 lifted in step (1) to move together to the sawing section 3.

[0079] (3) The lifting rod 121 drives the lifting plate 122 to lower, and the lifting plate 122 drives the bar 5 raised in step (1) to fall together.

[0080] (4) The transmission motor 135 drives the transmission roller 132 connected to it to rotate in the forward direction. Since the pulleys 133 on the two adjacent transmission rollers 132 are driven by the belt 134, all transmission rollers 132 rotate in the same direction, so that the bar 5 lifted in step (1) is transferred to the table 91 of the band saw 9 to realize the loading operation.

[0081] (5) After the feeding is completed, turn off the transmission motor 135. The lifting rod 121 drives the lifting plate 122 to lower further, so that the support plate 1311 on the transmission seat 131 is lower than the bar material 5 on the feeding section 2. The moving motor 114 drives the gear 115 to reverse, so that the moving seat 113 is reset to the end of the feeding section 2 near the stop seat 4, ready for the next feeding.

[0082] Based on the working principle described above in Embodiment 3, it can be seen that Embodiment 3 has the following effects:

[0083] The lifting assembly 1 in the background technology can only convey the bar stock 5 from the feeding section 2 to the sawing section 3, and cannot convey the bar stock 5 along the axial direction of the bar stock 5, which is not suitable for the layout of the band saw 9 located in front of the sawing section 3.

[0084] In this embodiment 3, by setting up a transmission module, the bar stock 5 can be transmitted along the axial direction of the bar stock 5 after it is transmitted to the sawing section 3, so that the bar stock 5 can be smoothly transmitted to the band saw 9 located in front of the sawing section 3, thus improving adaptability.

[0085] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
