Background technique

The mold is made on the basis of metal blanks (ie raw materials), using machine tools such as machining centers through cutting and drilling. proportional. However, the molds that can generally be processed by CNC machine tools such as machining centers are not small in size, so the weight of the metal blanks is heavier. Generally, the metal blanks are transported directly to the workshop by a transport vehicle, and then a forklift is used. and other engineering vehicles are transported from the transport vehicle and directly transported to the processing center for loading. The advantage of this feeding method is that it does not require much manpower to complete the handling. Although there are still some links that require workers and forklifts to load the machining center together, the forklift can also provide certain help; the disadvantage is that the forklift is too bulky It is large and requires a special person to drive. The key is that it can only fork one piece of metal blank at a time, and it also needs to travel in a wide passage, which reduces production efficiency. Due to the fire protection needs in the workshop, only electric forklifts can be purchased. At present, the price of electric forklifts is slightly higher than that of internal combustion engine forklifts. The price of a single forklift is generally between 16,000 yuan and 30,000 yuan, which is too expensive.

Compared with other machine tools, the machining center has some special requirements when feeding materials. The general configuration is that a base is enclosed with a baffle plate, and the base is provided with a processing table whose length and width are smaller than that of the base.

Detailed ways

Example 1.

This embodiment provides an alternative solution to the forklift, which can achieve the effect of the forklift when transporting the metal embryos, and also has the effect that the forklift does not have.

What needs to be determined first is that in this embodiment, the side with the pincer-shaped extension 3 is the front, and the other side opposite to the pincer-shaped extension 3 is the back. The use flow and structural principle of this embodiment are as follows:

1. The charging process

1. Turn the base 1 so that the back faces the transport vehicle mounted on the metal blank; 2. Use a forklift to transport the metal blank on the transport vehicle to the lifting platform 4; 3. Start the lifting mechanism 5 to drive the metal blank already mounted on the metal blank The lifting platform 4 of the blank is lifted and lowered, so that the unloaded lifting platform 4 can be lifted to a suitable height; 4. Then use a forklift to transport the metal blank on the transport vehicle to the unloaded lifting platform 4;

2. Unloading process

1. Push the base 1 or the stringer 2 to transport the metal blank to the machining center; 2. Turn the base 1 so that the front side faces the machining center and is in close contact; 3. When the base 1 and/or the stringer 2 is close to the machining center , the support plate 6 of the pliers-shaped extension 3 extends into the machining center to contact the workbench, and is flush with the workbench; 4. Start the lifting mechanism 5 to drive the lifting platform 4 that needs to be unloaded to move to the support plate. 6. The same height; 5. Push the metal blank on the lifting platform 4 down from it, and the metal blank passes through the support plate 6 and is finally transported to the worktable; 6. Push the base 1 to other machining centers to continue unloading.

In this embodiment, according to the height of the working table of the machining center, the pallet 6 of the pincer-shaped extension 3 is set at the same height as the machining table, and the pallet 6 is fixed on the longitudinal beam 2. Approaching the machining center, the pallet 6 is closer to the table until the pallet 6 touches the edge of the table. Pushing the metal blank located on the lifting platform 4 can make it slide toward the pallet 6, and then slide into the worktable by means of the pallet 6 to complete the feeding.

The lifting mechanism 5 can use any feasible product, but it needs to meet the following requirements. One is that the lifting stroke can meet the lifting of any layer in the multi-layer lifting platform 4 to the height of the pincer-shaped extension 3. When storing materials, the lifting platform 4 can be stably hovered at a specified height for a long time to meet the basic requirements of storing materials for a long time. There are various solutions in existing products that can meet the above requirements, such as hydraulic cylinders or electric push rods, etc. In this embodiment and all other embodiments, the number of lifting mechanisms 5 is not limited, but preferably, at least two There is a lifting mechanism 5, that is, at least two lifting mechanisms 5, and each lifting mechanism 5 should be in the middle of the longitudinal beam 2 to ensure that the force applied by the lifting mechanism 5 to the lifting platform 4 can make the lifting platform 4 stable. the lift.

The carriage 8 of the lifting platform 4 slides in the chute 7 on the longitudinal beam 2, and the lifting mechanism 5 can be connected with the sliding frame 8. In theory, each lifting platform 4 can be equipped with an independent lifting mechanism 5, but in order to simplify the structure To improve the efficiency, the carriages 8 of the multiple lifting platforms 4 are connected together through the rack, so that the multiple lifting platforms 4 can be lifted and lowered at the same time. At this time, only one lifting mechanism 5 can control the lifting and lowering of all the lifting platforms 4. Even if more than one lifting mechanism 5 is provided to provide lifting and lowering as required, the required number of lifting mechanisms 5 can be compressed as much as possible. It should be noted that although a forklift can be used instead of a forklift to transport the billet, a forklift still needs to be used to fork off the billet from the transport truck and transport it to the lifting platform 4 . The significance of the present embodiment is to replace the forklift and improve the practicability of the entire material conveying slow link. Increase the degree of adaptation with the machining center. Under the guidance of the meaning of this invention, no manpower is allowed during the conveying process of the billet from the forklift to the lifting platform 4, so that the billet on the fork frame can be free from The obstacle is transferred to the lifting platform 4, an opening 9 is opened on the lifting platform 4, and the pliers-shaped extension 3 is opened on the longitudinal beam 2 on the front side of the lifting platform 4, and the forklift needs to avoid the pliers when conveying the material. The shape of the extension 3, so the opening 9 is opened on the back of the lifting platform 4. After the fork frame of the forklift is inserted into the opening 9, the fork frame is controlled to descend, and the blank is left on the lifting platform 4. In order to make the lifting action of the lift platform 4 smoother, a pulley can be provided on the carriage 8, and the carriage 8 can slide in the chute 7 through the pulley.

The pincer extension 3 consists of two pallets 6 forming a pincer shape. Although the pallet 6 is fixed on the longitudinal beam 2, it acts as a bridge for conveying materials to the workbench. If the distance between the two pallets 6 is as wide as the lifting platform 4, it cannot support the material. The spacing between the pallets 6 must be reduced, and the spacing should be smaller than the edge length or width of the lifting platform 4, and the two pallets 6 must be symmetrically arranged so that the distances between the two pallets 6 from the central axis of the lifting platform 4 are equal. This is the support plate 6 needs to extend to the opposite inner side,

The carriage 8 may take any shape and any structure, but it is more preferable to take a T-shape or a T-shape. The tail 11 of the T-shaped carriage 8 is connected with the lift platform, and its head 10 is bifurcated toward both sides, so the carriage 8 can slide in the front and rear two chute 7 on the same side at the same time, such as the lift platform The right side has two longitudinal beams 2, one in front and one behind, the carriage 8 of which can slide in the sliding grooves 7 of the two longitudinal beams 2 on the right side.

In this embodiment, there can also be a solution in which the lifting platform 4 has three or three layers. In order to reduce the burden of the lifting mechanism 5, the lifting platform 4 can be divided into upper and lower groups for independent control. For example, the first layer and the The lifting platform 4 on the second layer (or the bottom and the middle lifting platform 4) is used as the lower group, which is controlled by a lifting mechanism 5, and the lifting platform 4 on the third layer is used as the upper group alone, and another lifting mechanism is used. 5 controls the lifting, the lifting mechanism 5 for controlling the third floor can be fixed on the top of the longitudinal beam 2 through the frame.

Example two.

In this embodiment, the structure of the carriage 8 is optimized. In this embodiment, the carriage 8 adopts an H-shaped structure instead of a T-shaped structure. The length of the T-shaped structure in the longitudinal direction, the longer the longitudinal length of the carriage 8 is, the easier it is for the lifting platform 4 to maintain a horizontal state. Moreover, it can better adapt to the scheme of the multi-layer lifting platform 4. Taking the two-layer lifting platform 4 as an example, the carriages 8 of the upper layer and the lower layer can be connected end to end to further increase the length of the carriage 8 in the longitudinal direction, so that the Lifting platform 4 is more stable. At the same time, in order to reduce the frictional force, the carriage 8 of the H-shaped structure can still be provided with pulleys, and slide in the chute 7 through the pulleys.
