Description

Technical Field

[0001] This utility model relates to the field of drill bit processing technology, and more specifically, to a high-speed steel drill bit blank stacking device. Background Technology

[0002] High-speed steel drill bits are metal cutting tools made primarily of high-speed steel (HSS), whose typical components include alloying elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. After heat treatment, these drill bits achieve high hardness (HRC62-67), high wear resistance, and excellent red hardness (maintaining cutting performance even at approximately 600℃), making them suitable for drilling holes in materials such as carbon steel, alloy steel, cast iron, and non-ferrous metals.

[0003] During the production process, high-speed steel drill bits require material preparation and pretreatment before entering the CNC grinding process. First, based on the drill bit diameter and total length requirements, high-speed steel bars are cut to a fixed length using an alloy bar cutter or wire EDM equipment to create blanks. Then, end faces are flattened and outer diameters are chamfered to eliminate unevenness and burrs, laying the foundation for subsequent precise clamping and grinding. Currently, some production lines still use raw material bins or simple racks to store blanks, resulting in cluttered placement, inconvenient retrieval, and increased risk of collision and wear between blanks, affecting subsequent processing quality and tool precision.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 3As shown, this utility model discloses a high-speed steel drill bit blank stacking device. The high-speed steel drill bit blank stacking device includes a base 100, a storage rack 200, and a feeding mechanism 300. The storage rack 200 is provided with a first baffle 210 and a second baffle 220, which are arranged in a V-shape on the base 100. A material retrieval groove 230 is provided at the connection between the first baffle 210 and the second baffle 220. A baffle plate 240 is provided on the storage rack 200. The feeding mechanism 300 is provided with a pull rod 310, one end of which is provided with a push plate 320. The end of the push plate 320 penetrates into the material retrieval groove 230 and can reciprocate along the length of the material retrieval groove 230. Specifically, in this embodiment, the high-speed steel drill bit blank 400 is placed between the V-shaped first baffle 210 and the second baffle 220. Under the influence of gravity, the billet 400 rolls along the inclined surface of the baffle, achieving automatic centering and stacking, and gathers in the picking trough 230 at the connection between the two baffles. The bottommost billet 400 falls naturally into the picking trough 230. The pull rod 310 of the feeding mechanism 300 drives the push plate 320 to reciprocate linearly; when the push plate 320 moves forward, it pushes out the single billet 400 at the front of the picking trough 230, completing the feeding action; when the push plate 320 retracts, subsequent billets 400 are automatically replenished to the picking position under the influence of gravity. The baffle 240 set above the picking trough 230 can intercept other billets 400, preventing the billets 400 from falling out of the storage rack 200 due to friction during the picking process. Through the design of this structure, the automatic centering and orderly arrangement of the billets 400 are achieved by using the V-shaped baffle structure, effectively avoiding the disorderly stacking and mutual collision of the billets 400. The cooperation between the pusher plate 320 and the feeding chute 230 enables the precise feeding of each billet 400, ensuring the continuity and reliability of the feeding process. The baffle plate 240 structure further improves the stability of the storage rack 200, preventing the billet 400 from accidentally falling out during feeding. The entire device structure effectively improves the automation level of billet 400 management, providing a stable supply guarantee for subsequent processing steps.

[0025] In some embodiments of this utility model, the included angle between the first baffle 210 and the second baffle 220 is α, wherein 65°≤α≤90°. Specifically, in this embodiment, the included angle α between the first baffle 210 and the second baffle 220 is set between 65 degrees and 90 degrees. This angle range can effectively prevent the billet 400 from getting stuck in the storage rack 200 and being unable to enter the picking slot 230. When the included angle α is within this range, as the billet 400 rolls along the inclined surface of the first baffle 210 or the second baffle 220 under the action of gravity, its center of gravity position and contact force distribution tend to be reasonable. The frictional resistance and extrusion force between the billets 400 are balanced, avoiding the billets 400 from being squeezed and stuck due to excessively small angles or from being scattered and unstable due to excessively large angles. This ensures that the bottommost billet 400 can fall smoothly and naturally into the picking groove 230. The optimized design of the included angle α significantly reduces the risk of the billet 400 getting stuck in the storage rack 200, ensuring the reliability of the automatic centering and positioning of the billet 400. This angle range allows the billet 400 to continuously and orderly converge into the picking groove 230 under the action of gravity, improving the continuity and stability of the feeding process, avoiding the interruption of material supply caused by the billet 400 being stuck, and providing a smooth supply of billet 400 for subsequent processing steps.

[0026] In some embodiments of this utility model, the storage rack 200 is provided with a partition 250, which is vertically inserted onto the first baffle 210 and the second baffle 220. The partition 250 divides the storage rack 200 into a raw material area 201 and a finished product area 202, and a material chute 230 is provided in the raw material area 201. Specifically, in this embodiment, the raw material area 201 is used to store the blanks 400 to be processed and is supplied in an orderly manner through the material chute 230; the finished product area 202 can be used to temporarily store the drill bits that have been processed. This partitioned management effectively avoids the mixing between raw materials and finished products, prevents duplicate processing or missed processing caused by the chaotic flow of blanks 400, and improves the organization and management efficiency of the production site.

[0027] In some embodiments of this utility model, a mounting hole 101 is provided on the base 100, and the pull rod 310 is slidably disposed in the mounting hole 101; a clearance hole 102 is provided between the mounting hole 101 and the feeding groove 230, and the push plate 320 is slidably disposed in the clearance hole 102. Specifically, in this embodiment, the mounting hole 101 provides a stable linear motion guide for the pull rod 310, ensuring that the movement trajectory of the push plate 320 is consistent with the axis of the feeding groove 230. The design of the clearance hole 102 provides the necessary movement space for the push plate 320 while avoiding interference from the base 100 on the movement of the push plate 320. This separate hole layout allows the driving movement of the pull rod 310 and the feeding movement of the push plate 320 to work in coordination without interfering with each other.

[0028] In some embodiments of this utility model, the feeding mechanism 300 includes a return spring 330, a retaining ring 311 on the pull rod 310, and a sleeve 340 on the outer edge of the mounting hole 101. The return spring 330 is sleeved on the pull rod 310, with one end of the return spring 330 abutting against the retaining ring 311 and the other end abutting against the sleeve 340. Specifically, in this embodiment, the return spring 330 of the feeding mechanism 300 is sleeved on the pull rod 310, with one end of the spring abutting against the retaining ring 311 of the pull rod 310 and the other end abutting against the sleeve 340 on the outer edge of the mounting hole 101. When the pull rod 310 drives the push plate 320 to complete the feeding action, the return spring 330 generates a restoring force due to compression, driving the pull rod 310 to automatically retract to the initial position, preparing for the next feeding cycle. The automatic reset of the feeding mechanism 300 is achieved through the elastic restoring force of the spring, ensuring the continuous and stable reciprocating motion of the push plate 320 without the need for additional power components. The pre-compression of the return spring 330 can be adjusted by the relative position of the retaining ring 311 and the sleeve 340, thereby controlling the rhythm and force of the feeding action. This design not only improves the reliability and continuity of equipment operation.

[0029] Furthermore, a T-shaped handle 350 is provided at the end of the pull rod 310 away from the push plate 320, passing through the sleeve 340. The T-shaped handle 350 facilitates the operator's control of the movement of the pull rod 310.

[0030] In some embodiments of this utility model, the sleeve 340 and the mounting hole 101 are threadedly connected. This threaded connection facilitates the installation of the feeding mechanism 300. Specifically, when assembling the feeding mechanism 300, simply screwing in the sleeve 340 is sufficient to position and install the return spring 330, significantly improving assembly efficiency. The threaded connection also facilitates adjustment or replacement of the sleeve 340 during later maintenance, effectively reducing equipment maintenance costs.

[0031] In some embodiments of this utility model, channel steel 110 is provided at each of the four corners of the base 100. The upper end of the channel steel 110 is fixedly connected to the storage rack 200, and the lower end of the channel steel 110 is fixedly connected to the base 100. Specifically, in this embodiment, by providing the channel steel 110, the first baffle 210 and the baffle can be stably supported.

[0032] In some embodiments of this utility model, the base 100 includes a connecting rod 120, which is horizontally inserted into the channel steel 110. The partition plate 250 has slots 251 on both sides, which engage with the connecting rod 120. Specifically, in this embodiment, the modular installation of the partition plate 250 is achieved through the cooperation of the connecting rod 120 and the slots 251. This connection method makes the disassembly and assembly of the partition plate 250 simple and quick, facilitating the adjustment of the spatial ratio between the raw material area 201 and the finished product area 202 according to production needs. The horizontal support provided by the connecting rod 120 ensures the structural stability of the partition plate 250 when bearing the blank 400, while the slot 251 connection method simultaneously ensures reliable fixation between the partition plate 250 and the base 100, effectively preventing positional displacement due to vibration or load changes. This design not only meets the functional requirements of zoning management but also improves the convenience of equipment maintenance and adjustment. In addition, the connecting rod 120 can also serve as a fulcrum for moving this device.

[0033] In some embodiments of this utility model, a suction cup 130 is provided at the bottom of the base 100. Specifically, in this embodiment, the device can be stably fixed by providing the suction cup 130.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
