Description

Device capable of preventing workpiece from being knocked in blanking process

Technical Field

The utility model relates to the field of production and conveying of spare and accessory parts, in particular to a device capable of preventing a workpiece from being knocked in a blanking process.

Background

Screws are a common type of fastener and have very wide application in the mechanical industry. The screw thread on the screw needs to be obtained through thread rolling machine processing, the screw is processed out the screw under the effect of the tooth plate mechanism on the thread rolling machine, the movable tooth plate in the tooth plate mechanism moves horizontally relative to the static tooth plate, the tooth-shaped cutters on the inner walls of the movable tooth plate mechanism are utilized to rub out the screw thread on the surface of the polished rod screw, and when the screw thread is rubbed out, the screw can be rapidly discharged from the outlet of the tooth plate mechanism under the effect of the movable tooth plate and falls into a container arranged below the tooth plate mechanism. However, the conventional thread rolling operation has a problem that the screws falling into the container collide with each other, so that damage is caused, and the qualification rate of the screws is affected.

If the height of the container is increased, namely the height difference between the dental lamina mechanism and the container is shortened, although the problem of partial bruising can be avoided, the initial speed of the screw discharged from the dental lamina mechanism is relatively high, and the problem of bruising generated after different screws collide still cannot be completely avoided; some manufacturers will set a sloping plate of a through container below the dental lamina mechanism, so that the screws falling on the sloping plate naturally slide into the container, but because the surface of the screws is relatively viscous oil in the process, the screws may be stuck on the sloping plate under the action of the oil after falling on the sloping plate, and thus the screws at the rear part may collide with the screws stuck on the sloping plate, and the problem of mutual collision still exists.

There is thus a need for a method or apparatus that solves the above-mentioned problems.

Disclosure of Invention

The utility model aims to solve the technical problems, and provides the device which has the advantages of simple structure, ingenious design and reasonable layout, and can effectively prevent falling workpieces from being damaged due to collision and influence on the qualification rate of the workpieces.

The technical scheme of the utility model is as follows: a device capable of preventing workpieces from being knocked in blanking process is characterized in that: the device comprises a rotating shaft 2 rotatably supported at the outlet of a thread rolling machine 1, wherein the two ends of the rotating shaft 2 are provided with discs 3, the rotating shaft 2 is also provided with three material receiving plates 4 uniformly distributed in the circumferential direction, the two ends of each material receiving plate 4 are respectively connected with the two discs 3, the surface of each material receiving plate 4 is provided with a rubber layer 5, the end part of the rotating shaft 2 is provided with a driven tooth 6, the driven tooth 6 is connected with a driving tooth 8 through a transmission chain 7, the driving tooth 8 is arranged at the center of a main machine wheel 9 of the thread rolling machine 1, and a collecting container 10 is arranged below the rotating shaft 2.

Compared with the prior art, the utility model has the following advantages:

the device capable of preventing the workpiece from being knocked in the blanking process is simple in structure, ingenious in design and reasonable in layout, and aims at the problem that after the screw rolling operation of the traditional screw rolling machine, the screws are knocked due to mutual collision, a special structure is designed, a rotatable mechanism is arranged between an outlet of a tooth plate mechanism of the screw rolling machine and a collecting container below the tooth plate mechanism, the mechanism is directly driven through a main machine wheel of the screw rolling machine, the dropped screws can be separated, the screws cannot collide at a relatively fast stage, and finally the screws are fed into the collecting container one by one through rotation, so that the knocking caused by collision between the screws can be effectively prevented, and the qualification rate of the screws is ensured. The device has the advantages of simple manufacturing process and low manufacturing cost, so that the device is particularly suitable for popularization and application in the field and has very broad market prospect.

Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1 and 2: the utility model provides a device that can prevent work piece from colliding with in blanking process, it includes a pivot 2 that rotates to support in the export of thread rolling machine 1 department, the both ends of pivot 2 are provided with disc 3, still be provided with three on pivot 2 and connect flitch 4 evenly distributed in the circumferencial direction, just connect the both ends of flitch 4 to link to each other with two discs 3 respectively, the surface of flitch 4 is provided with the rubber coating 5, the tip of pivot 2 is provided with passive tooth 6, passive tooth 6 links to each other with initiative tooth 8 through drive chain 7, and initiative tooth 8 then sets up in the centre of a circle department of the host computer wheel 9 of thread rolling machine 1 the below of pivot 2 is provided with collection container 10.

The working process of the device capable of preventing the workpiece from being knocked in the blanking process is as follows: after the thread rolling machine 1 is started, a main machine wheel 9 arranged on the thread rolling machine starts to rotate, and a driving pair consisting of a driving tooth 8, a driving chain 7 and a driven tooth 6 drives a rotating shaft 2 to rotate, the proportion relation between the rotating speed of the rotating shaft 2 and the rotating speed of the main machine wheel 9 can be controlled by selecting the driving tooth 8 and the driven tooth 6 with proper transmission ratios so as to ensure that the rotating speed of the rotating shaft 2 and the discharging speed of the thread rolling machine 1 are matched with each other,

the screw plate mechanism 11 on the thread rolling machine 1 is driven by the main machine wheel 9 to act at a certain frequency, threads are rubbed on the polished rod screws entering the screw plate mechanism, the screws which finish the thread rolling operation are separated from the outlet end of the thread rolling machine 11 and firstly fall into a material receiving area between two adjacent material receiving plates 4, and as the rotating speed of the rotating shaft 2 and the discharging speed of the thread rolling machine 1 are mutually matched, each screw can be ensured to enter an empty material receiving area, so that a plurality of screws are prevented from colliding with each other;

when the opening of the material receiving area is upward, the screws can stay in the material receiving area, and when the opening of the material receiving area is downward along with the rotation of the rotating shaft 2, the screws naturally slide into the collecting container below under the action of gravity, that is to say, when the rotating shaft 2 rotates, the material receiving area can sequentially catch the screws discharged from the thread rolling machine 1 and convey the screws into the collecting container one by one;

the initial speed of the screw discharged from the dental plate mechanism 11 is relatively high, so that the screw firstly enters the material receiving area, and the rubber layer 5 is arranged on the surface of the material receiving plate 4, so that the rubber layer 5 can play a role in buffering, and the screw collided with the rubber layer 5 is prevented from being damaged;

in the process of falling the screw from the material receiving area to the collecting container, the screw naturally slides down, so that the falling speed is relatively low, and even if the screw collides with other screws in the collecting container, the collision force of the screw does not cause the damage of the screw.
