Description

Technical Field

[0001] The utility model belongs to the field of forging processing, and particularly relates to an anti-collision device for forgings. Background Art

[0002] At present, with the continuous development of the industry, the competition between industries has become increasingly fierce, and price wars have become the norm. In addition, customers' requirements for product quality are also constantly improving. Effectively reducing costs and improving product quality have become the key to enhancing the competitiveness of enterprises.

[0003] The process route for producing forgings is usually: blanking - heating - die forging - trimming - heat treatment - shot peening - inspection - warehousing. Among them, the trimming, heat treatment, and shot peening processes are prone to collisions. Especially in the trimming and heat treatment processes, since the forgings are in a hot state, they are easily damaged by some small impact forces. And the surface quality of the forgings is an important characteristic that is most easily recognized. In many cases, the dimensions and performance of the forgings have met the requirements of customers, but due to some unnecessary collisions during the production process, the originally qualified products fail to meet the surface quality requirements of customers, resulting in returns for rework, and in severe cases, even direct scrapping. If only relying on the workers in production to avoid this problem, the workers need to pick up the forgings one by one and put them into the box, which is time-consuming and laborious, and greatly wastes human and material resources. This undoubtedly increases a large amount of additional costs for the enterprise. Avoiding unnecessary collisions during the production process is extremely urgent. The anti-collision blanking device disclosed in the publication number CN219211499 U has a too complex structure. There is a receiving plate between the discharge channel and the material box. Although it can also prevent the collisions generated when the forgings fall, it cannot reduce the pressure of the forgings on the receiving plate, and the receiving plate is prone to damage, reducing the service life of the receiving plate.

[0004] Therefore, the above problems should be considered and solved during the production process of the above forgings. Summary of the Utility Model

[0005] Aiming at the above problems, the purpose of the present utility model is to provide an anti-collision device for forgings, which mainly solves the problem that the forgings are easily damaged during the production and manufacturing process, improves the surface quality and the qualified rate of the products, and reduces costs.

[0006] The specific technical solution of the present utility model is as follows: The present utility model provides an anti-collision device for forgings, including a frame and a buffer mechanism arranged on the frame. The frame is a telescopic structure, including a fixed frame and a movable frame arranged opposite to each other on the left and right. Along the telescopic direction, a plurality of hooks are arranged on the opposite sides of the frame. The buffer mechanism includes at least one layer of iron chain layer, and both ends of the iron chain layer are provided with lock catches for connecting the hooks.

[0007] A further improvement of the present utility model lies in that: the fixed frame is in a "C" shape, the inner parts of the upper and lower side beams thereof are cavities, a plurality of adjustment holes are provided at the top, the upper and lower side beams of the movable frame are correspondingly inserted into the cavities, and at least one fixing hole adapted to the shape of the adjustment holes is provided, and the adjustment holes and the fixing holes are connected by fastening pins.

[0008] A further improvement of the present utility model lies in that: the iron chain layer includes a layer of iron chains arranged side by side, and gaps are provided between adjacent iron chains.

[0009] A further improvement of the present utility model lies in that: buffer springs are provided at both ends of the iron chain, and the lock buckle is arranged at the other end of the buffer spring.

[0010] A further improvement of the present utility model lies in that: the length of the iron chain is greater than the longest distance after the frame expands and contracts.

[0011] A further improvement of the present utility model lies in that: the buffer mechanism includes two iron chain layers, and the length of the lower iron chain layer is greater than the length of the upper iron chain layer.

[0012] A further improvement of the present utility model lies in that: rotatable brackets are hinged to the bottom of both sides of the frame.

[0013] The beneficial effects of the present utility model are as follows: its structure is simple, the manufacturing cost is very low, it is durable and convenient to replace; after adding an anti-collision device above the iron frame for placing forgings, the collision problem of the product has been greatly improved, reducing the impact on the surface quality of the product; while the product qualification rate has increased significantly, the production efficiency is ensured, and the production cost is effectively reduced; and the anti-collision device itself has a low manufacturing cost, is durable and convenient to maintain, and is suitable for anti-collision of forgings.

[0019] To deepen the understanding of the present utility model, the following will further describe the present utility model in detail in conjunction with the accompanying drawings and embodiments. The embodiments are only used to explain the present utility model and do not limit the scope of protection.

[0020] This embodiment provides an anti-collision and anti-knock device for forgings, which includes a frame 1 and a buffer mechanism arranged on the frame. The frame 1 is a telescopic structure, including a fixed frame 2 and a movable frame 3 arranged opposite to each other left and right. The fixed frame 2 is in a "C" shape, and the inner parts of its upper and lower side beams are cavities. There are a plurality of adjustment holes 4 on the top. The upper and lower side beams of the movable frame 3 are correspondingly inserted into the cavities, and at least one fixing hole 5 matching the shape of the adjustment hole 4 is arranged on the movable frame. The adjustment hole 4 and the fixing hole 5 are connected by a fastening pin 6 and fixed by a nut 11. A plurality of hooks 7 are arranged on the opposite sides of the fixed frame 2 and the movable frame 3 along the telescopic direction. The buffer mechanism includes a layer of iron chain layer 8. The iron chain layer 8 is a layer of iron chains arranged side by side, and there are gaps between adjacent iron chains. The length of the iron chain is greater than the longest distance after the frame 1 is telescoped. Buffer springs 9 are arranged at both ends of the iron chain, and a lock catch 10 for connecting the hook 7 is arranged at the other end of the buffer spring 9. Rotatable brackets 12 are hinged at the bottom on both sides of the frame 1.

[0021] The working principle of the anti-collision and anti-knock device for forgings provided by this embodiment is as follows: In the trimming, heat treatment, and shot peening processes, open the brackets 8 at the bottom of the frame 1 so that the anti-collision and anti-knock device is placed above the material box for placing forgings; loosen the fastening pin 6 to adjust the width of the frame 1 so that the width of the frame is consistent with the width of the conveyor belt; then adjust the gap between the iron chains according to the size of the forgings to ensure that the forgings can be blocked by the iron chains and can fall into the box at the same time. In this embodiment, due to the particularity of the forgings, general buffers cannot resist their high temperature, so iron chains are used to block them to reduce the magnitude of their falling force. After being intercepted by one or more layers of the iron chain layer, finally the forgings will not be damaged, thereby improving the surface quality of the forgings and the product qualification rate.

[0022] The above are only the preferred and feasible embodiments of the present utility model, and they are not limitations to the present utility model. The present utility model is not limited to the above examples either. Those skilled in the art of this technology, within the substantial scope of the present utility model, the changes, modifications, additions, or substitutions made should also belong to the protection scope of the present utility model.
