Description

Clamp for spring assembly

technical field

The invention relates to the technical field of storage cage assembly and processing, in particular to a clamp for spring assembly used for assembling steel wire springs between storage cage nets and nets.

Background technique

The storage cage has the advantages of fixed storage capacity, neat stacking, clear storage, and easy inventory inventory. It also improves the effective utilization of storage space. In addition, the product is durable, easy to transport, and can be reused, which can effectively reduce the labor consumption and packaging costs of warehousing enterprises. This product can not only be used in factory production workshops, but also can be used in supermarkets as display promotion and storage, and can be used outdoors.

The nets of the storage cage are connected by springs. After the springs are installed, in order to avoid the deformation of the ends of the springs and the scratches on the hands of the workers, the ends of the steel wires at both ends of the spring should be bent toward the inside of the spring ring. . The traditional bending method is to use tool pliers to clamp the head of the steel wire and bend it inward, but the tool pliers are too thick, which is inconvenient and easy to damage the shape of the spring end. Every time you operate, you must first open the pliers mouth, and then clamp it The steel wire head is then bent. After a long time, it is difficult to use the hands, the production efficiency is low, and the tool pliers are expensive, which increases the production cost.

Contents of the invention

In order to solve the technical problems in the above-mentioned background technology, the present invention provides a clamp for spring assembly, which has a simple structure, less material, low cost, high production efficiency and labor saving.

Technical scheme of the present invention is realized like this:

A clamp for spring assembly, comprising a clamp body, the clamp body is provided with a jaw and a jaw, the clamp body is provided with two pieces, and the two pieces of the clamp body are one positive and the other reversed by a rivet at the jaw The jaws are hinged to each other, and the jaws are hinged in stacked jaws, which is characterized in that the thickness of the clamp body is 3-4mm, and the clamp body also includes a pincer arm, and the pincer arm is located on the left upper part of the jaws. The jaw of the pliers is set at the lower right part of the pliers jaw, and the top of the pliers arm is horizontally fixedly connected with a long strip handle, and the upper end of the pliers arm is provided with a connecting part under the handle, and the connecting part is centered on the hinge point of the pliers jaw. In the fan-shaped plate, the connecting parts of the two clamp bodies are arranged opposite to each other, the connecting parts are provided with a plurality of locking teeth, and the locking teeth at the connecting parts of the two clamp bodies are locked together.

Further, the left side of the mouth of the pliers is provided with a slot, and the slots of the two clamp bodies are opposite to form an inverted U-shaped slot. The slot is used to hold the spring steel wire. The right side of the lower end of the mouth of the pliers The surface is inclined from the outside to the inside, and the pliers mouth is tapered with a large top and a small bottom.

Further, the locking tooth shape standard adopts the locking tooth shape standard of surgical instruments.

Further, the clamp body is made of high-quality carbon tool steel.

Further, the handle is made of round steel.

Further, the handle is provided with a plastic sleeve.

Further, an arc groove is provided on the inner wall of the card slot.

Further, the inner wall of the card slot is provided with a transverse V-shaped groove.

The working principle of the present invention: before operation, according to the diameter of the spring steel wire, adjust the number of locking teeth of the left and right locking teeth, and make the width of the clamp slot correspond to the diameter of the spring steel wire. During operation, lock the slot The end of the spring steel wire can be bent and screwed into the spring coil by rotating the handle. The whole process only takes 2 to 3 seconds, and the production efficiency is high; because the clamp body is made of thin plate and the jaw is set in a tapered shape , so that the jaws can easily clamp the end of the spring steel wire without damaging the shape of the spring. Because the body of the clamp is equipped with a clamp arm, the handle is at the upper end of the clamp arm, which lengthens the rotating arm, which saves effort in use. The clamp used for spring assembly is simple in structure, less in material and low in cost; multiple locking teeth can adjust the width of the clamping groove, so that the clamp is suitable for spring steel wires of various specifications.

Compared with the existing tool pliers, the invention has the advantages of simple structure, less material consumption, low cost, time-saving and labor-saving, greatly improved production efficiency, and is applicable to spring steel wires of various diameters and specifications.
