Description

A structure that is convenient for the position limit of cold heading machine cutting and conveying

technical field

The invention relates to the technical field of position-limiting structures, in particular to a structure that facilitates position-limiting during cutting and conveying of cold heading machines.

Background technique

Cold heading machine is a special equipment specially used for mass production of nuts, bolts and other fasteners. The cold heading process is suitable for products with large batches and various specifications.

The cold heading machine is mainly used for the cold heading of the wire rod. The wire rod after the cold heading needs to be cut. In the traditional cutting process, the interval between the cutting knife and the antique time is mostly used for cutting, or the wire rod is limited and then cut, but The traditional limit structure has a small application range, cannot be applied to different types of wires, and is prone to material jams during the cutting process, so it is necessary to improve.

Contents of the invention

The present invention provides a position-limiting function applicable to various types of wire cutting, which can effectively prevent material jamming during cutting, and facilitates the position-limiting structure during material cutting and conveying of cold heading machines; it solves the problems existing in the prior art The limiting structure is single, and cannot be applied to wire structures of various types or sizes, and cannot prevent or solve technical problems of material jamming.

The above-mentioned technical problems of the present invention are solved by the following technical solutions: a structure that is convenient for the cutting and conveying of the cold heading machine, including a working box, the right side of the working box is the feeding end, and the working box is along the horizontal There is a feeding structure in the direction. The feeding structure includes several rotatable lower feeding rollers arranged evenly. The feeding structure also includes several upper feeding rollers corresponding to the upper feeding rollers. The upper feeding rollers Wire parts are transported between the lower feed roller, and the left side of the working box is provided with a shearing structure that can cut the wire parts. Limit structure for adjustment. When working, the wire parts enter the work box from the right side of the work box, and are conveyed to the left by the feeding structure. The lower feed roller contacts the top of the wire parts and plays a load-bearing role. The upper feed roller and the wire The bottom of the part is in contact, and the upper feed roller and the lower feed roller rotate in different directions to realize the conveyance of wire parts in different directions. The wire parts are transported to the limit structure through the feed structure for limit. The length of the cut wire part is adjusted. When the required cut length of the wire part is reached, the limit structure will limit the feeding of the wire part, so that the wire part stops feeding to the left, and then the shear structure The wire parts are cut, which can effectively ensure that the size of the wire parts cut each time is consistent and avoid errors.

Preferably, the shearing structure includes an inner cutter fixed to the outside of the wire part, the inner cutter is sleeved on the outside of the wire part, and the shearing structure further includes an outer cutter fixed to the left side of the inner cutter. The function of the shearing structure is to cut the wire parts. The inner cutter can not only cut the outer wall of the wire parts during the feeding and conveying process, such as cutting threads, but also play a role in guiding the wire parts. The outer cutter mainly It is to cut off the end of the wire part.

As a preference, the limiting structure includes a rotatable turntable, on which a side near the shearing structure is arranged in a circular arrangement with several limiting blocks, the limiting blocks are fixedly connected to the rotating disk through a positioning rod, and the limiting blocks are rotated on the On the positioning rod, a limiting groove corresponding to the wire structure is opened at the center of the limiting block. The function of the limit structure is to control the cutting length of the wire parts. The turntable drives the limit block to rotate, which can be driven by a servo motor. Each time the turntable rotates at a fixed angle, there will be a limit block and the wire part after each rotation. Center alignment, when the wire parts enter the limit slot, the limit block will play a blocking effect, stop the wire parts from continuing to be transported, and then cut the wire parts, turn the turntable to a fixed angle, so that the cut wire parts come out, avoiding Material jams during cutting, etc., and at the same time, it can ensure that the dimensions of the wire parts are all consistent during each cutting.

As a preference, the limiting structure further includes a spring fixed in the limiting groove, one end of the spring is fixed on the bottom of the limiting groove, the other end of the spring is fixed with a shrapnel, and the bottom of the limiting groove is also fixed. Limit lever. The wire parts will gradually come into contact with the shrapnel during the feeding and conveying process, and continue to compress the shrapnel and spring until the shrapnel contacts the limit rod, so as to ensure that the wire parts are of the same size every time they are cut. When the wire parts are rotated, the spring and shrapnel can push the cut wire parts out of the limit slot to ensure smooth discharge.

Preferably, the center of each limit block on the turntable can be aligned with the center of the wire part. The limit blocks are evenly arranged on the turntable, and the rotation angle of the turntable is fixed each time. The function of the limit block is to control the cutting length of the wire parts, so there will be a limit block every time the turntable drives the limit block to rotate a certain angle. The center of the wire is aligned with the center of the wire part to ensure that the wire structure can enter the limiting groove.

Preferably, a telescopic rod is provided between the turntable and the working box, one end of the telescopic rod is fixedly connected to the turntable, and the other end of the telescopic rod is fixed on the inner wall of the working box. The function of the telescopic rod is to adjust the distance between the turntable and the outer cutter, which can be adjusted when cutting wire parts of different sizes, and is suitable for cutting various wire parts.

As a preference, a storage box is provided under the limiting structure and the shearing structure, and the top of the storage box is open. The storage box is used to store the cut wire parts.

As a preference, a feed guide block is provided on the feed end of the working box, and the wire parts pass through the feed guide block and extend to the feed structure for delivery. The feeding guide block is used to guide the wire parts when feeding, so as to avoid the situation that the wire parts are skewed in the working box and affect the shearing.

Therefore, a structure of the present invention that is convenient for the limit of the cutting and conveying of the cold heading machine has the following advantages: it can be applied to the limit function of various types or sizes of wire rods during cutting after cold heading, and can effectively prevent or avoid jamming during cutting. The occurrence of material and so on.
