Description

Technical Field

[0001] This utility model relates to the field of bar stock processing technology, and more specifically, to a bar stock cutting conveying device. Background Technology

[0002] Bar stock processing refers to the process of cutting, turning, and milling round or hexagonal metal bars into the required shape and size of parts using lathes, milling machines, or CNC machine tools. It has the advantages of high precision, high efficiency, small batch production, and low cost, and is widely used in the manufacturing of small and medium-sized parts in industries such as automobiles, aviation, and bearings.

[0003] A search revealed an existing patent (publication number: CN220501945U) disclosing a bar stock conveying device, relating to the field of conveying equipment technology. This patent addresses the problem that while existing bar stock distribution and conveying devices can push bars, the pushing distance of the push rod in the distribution mechanism is fixed. This makes it difficult to adjust the pushing distance when dealing with bars of different lengths, thus reducing the practicality of the conveying device. The proposed device includes a conveying housing; a guide hopper is fixedly installed on the upper left side of the rear end face of the conveying housing, and a fixing plate is fixedly connected to the left end face of the conveying housing; a rotation drive mechanism is provided on the rear side of the fixing plate; through the cooperation of the insertion part, rectangular sliding sleeve, and actuating column, when dealing with another batch of bars of different lengths, the rotation radius of the actuating column can be adjusted according to the length of the bars, thereby adjusting the pushing distance of the pusher cylinder and improving the practicality of the conveying device.

[0004] In actual operation, the guide hopper relies solely on a fixed angle to allow the bar stock to roll freely, without any follow-up or forced material distribution mechanism at the discharge port. As a result, coarse and fine bars are easily jammed side-by-side or at an angle. Once jammed, the bars behind quickly pile up, instantly blocking the entire channel. Simultaneously, the rectangular sliding sleeve can only adjust its stroke in a stepped manner according to a preset hole spacing. When encountering bars with large diameter differences, the pusher either pushes them out of the way or pushes out multiple bars at once, causing the bars to misalign left and right on the conical rollers. Subsequent stations cannot receive materials normally, significantly reducing reliability and versatility. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a conveying device for bar cutting to solve the problems of easy jamming, misalignment, and poor adaptability.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bar cutting conveying device, comprising: a support frame; a feeding auxiliary device mounted on the support frame, the feeding auxiliary device being used to assist in feeding the bar; a bar pushing assembly mounted on one side of the feeding auxiliary device, the bar pushing assembly being used to convey the bar; a pushing adjustment assembly mounted on the bar pushing assembly, the pushing adjustment assembly being used to adjust and push the bar; and an auxiliary discharge assembly mounted on the front side of the feeding auxiliary device, the auxiliary discharge assembly being used to guide the bar to move.

[0007] Preferably, the material feeding auxiliary device includes: a material feeding frame fixedly installed on the top of the support frame, an auxiliary correction groove provided on the material feeding frame, an air outlet pipe provided inside the material feeding frame, a nozzle fixedly installed at one end of the air outlet pipe, a fan fixedly installed at the bottom of the material feeding frame, and the air outlet pipe communicating with the fan.

[0008] Preferably, the bar stock pushing assembly includes: a limiting frame fixedly installed on one side of the feeding frame, a support rod fixedly installed at the bottom of the limiting frame, a limiting rod fixedly installed inside the limiting frame, and a lead screw movably installed inside the limiting frame.

[0009] Preferably, the bar stock pushing assembly further includes: a movable block movably mounted on the outer surface of the limiting rod and the lead screw, a motor fixedly mounted on one side of the limiting frame, and the driving end of the motor fixedly connected to one end of the lead screw.

[0010] Preferably, the push adjustment component includes: a mounting plate fixedly installed on one side of the limiting frame, a limiting groove formed on the mounting plate, a moving groove formed on the mounting plate, one end of the moving block being movably sleeved inside the moving groove, a moving plate being fixedly installed on one end of the moving block, and the moving plate being movably installed inside the limiting groove.

[0011] Preferably, the push adjustment assembly further includes: a mounting groove formed on the movable plate, a limiting rod two fixedly installed inside the mounting groove, a push rod movably sleeved on the limiting rod two, an adjusting threaded rod movably installed inside the mounting groove, and an adjusting threaded rod threadedly sleeved at one end of the push rod.

[0012] Preferably, the auxiliary discharge assembly includes: a second support rod disposed on one side of the support frame, a movable frame fixedly installed on the top of the second support rod, an installation inclined plate fixedly installed inside the movable frame, a spring fixedly installed on one side of the installation inclined plate, an installation frame fixedly installed on one end of the spring, and a roller movably installed inside the installation frame.

[0013] Preferably, there are two sets of mounting ramps, springs, mounting frames, and rollers, and the two sets of mounting ramps, springs, mounting frames, and rollers are symmetrically arranged inside the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, upon startup, activates the fan, and the airflow through the outlet pipe and nozzle forms a uniform air cushion within the groove of the feeding frame, causing the bar stock to suspend and slide downwards. This reduces friction and prevents multiple bars from jamming side-by-side. The motor drives the lead screw to rotate, and the moving block moves smoothly forward along the limit rod and moving groove, pushing out the bars one by one. If the bar stock diameter changes, simply rotate the adjusting threaded rod; the push rod can then be finely adjusted back and forth within the mounting groove to ensure the push head always contacts the bar stock end face, preventing empty pushing or multiple bars from being pushed out. The pushed-out bars enter the auxiliary discharge assembly, where springs on the inclined plates on both sides automatically compress according to the bar stock thickness. Rollers elastically clamp and continue to guide the bar stock, ensuring its axis always coincides with the conveying center. This effectively solves the problems of "easy jamming and misalignment, poor adaptability," achieving continuous, precise, and low-failure feeding operations. Attached Figure Description

[0032] Based on Embodiment 1, a preferred embodiment of the bar cutting conveying device provided by this utility model is, for example... Figures 1 to 5 As shown: The auxiliary discharge assembly 5 includes: a second support rod 501 disposed on one side of the support frame 1, a movable frame 502 fixedly installed on the top of the second support rod 501, an installation inclined plate 503 fixedly installed inside the movable frame 502, a spring 504 fixedly installed on one side of the installation inclined plate 503, an installation frame 505 fixedly installed on one end of the spring 504, and a roller 506 movably installed inside the installation frame 505.
