Description

Die changing trolley

technical field

The utility model relates to a replacement device for stamping dies, in particular to a die changing trolley for horizontal push-pull dies.

Background technique

At present, the product width of the existing radiator sink plate forming station is 300mm, 400mm, 500mm, 600mm, 700mm, and 900mm in six specifications of molds. Therefore, in order to meet the needs of customers, we need to frequently replace stamping dies.

The existing mold plus the base weighs about eight tons, and a forklift cannot pull it out and put it back to its original position accurately; the cost of installing a crane and renting a car crane is too high; the existing mold changing trolley can only push and pull about four tons For heavy moulds, the height and carrying capacity of the mold changing trolley cannot meet the usage requirements.

Therefore, in order to change molds accurately, quickly and efficiently, thereby improving production efficiency and enhancing market competitiveness, an improved mold changing trolley is needed.

Utility model content

The mold changing trolley of the utility model comprises a first positioning block 1, a frame 7, a walking wheel 8, a transmission mechanism 9, a guide device 10, a positioning shaft 6 of the frame 7, a slider 11 and a pull-out shaft 2 of the slider, It is characterized in that at least 23 traveling wheels are arranged on each side of the two sides of the mold changing trolley.

The height of the mold changing dolly of the present utility model is 1000mm, the length is 2800mm and the width is 1400mm.

The guiding device 10 of the mold changing trolley of the present utility model is U-shaped or rectangular. The guide device is used to realize the horizontal push-pull of the slider and can be made of Q235\45# steel.

The frame 7 of the mold changing dolly of the present utility model is welded by 12mm-20mm thick steel plate and 8# channel steel.

The transmission mechanism 9 of the mold changing trolley of the utility model can adopt a chain transmission, such as through a double row of sprockets with Z=17, P=25.4 to transmit force, and use a long bolt tensioning motor and a reducer to realize chain tensioning .

The fixing device of the mold changing trolley of the utility model is fixed by the pull-out shaft 2 of the slider and the second positioning block 5 of the mold base, and the positioning shaft 6 of the frame 7 and the first positioning shaft for placing on the press body. Block 1 is fixed to implement.

The slider 11 of the mold changing trolley of the utility model is placed on the guide device 10 by its own weight, and the forward and backward movement of the motor and the reducer is used to realize the forward and backward movement of the slider, and then the two traction points on the slider are used It is connected with the hook of the second positioning block 5 of the mold base, and drives the mold to move according to the track of the guide rail to realize parallel push-pull movement.

Each walking wheel of the mold changing dolly of the present utility model can be made up of copper sleeve, roller shaft and roller.

The mold changing trolley of the utility model has the characteristics of accuracy, quickness and high efficiency.

Description of drawings

Fig. 1 is the working schematic diagram of the mold changing trolley of the present utility model.

Detailed ways

The technical scheme of the utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

As shown in Figure 1, the mold changing trolley includes a frame 7 and a positioning shaft 6 of the frame 7, the positioning shaft 6 is connected to the frame 7 through a circlip, and the first positioning block 1 is connected to the press by bolts or welding. machine. The second positioning block 5 of the mold base is connected to the base of the mold by bolts, welding or other conventional methods in the art; The output shaft 2, the pull-out shaft 2 is connected to the rotating arm 3 through a jumper, and the joint 4 is composed of a rotating arm shaft and a positioning plate, and is connected by a pin shaft.

When changing the mould, at first the positioning shaft 6 of the frame 7 is connected with the first positioning block 1 with a forklift to fix the mold changing dolly. Next, use a motor greater than 0.75kw to move the slider 11 to the mold, lift the rotating arm 3, and make the second positioning block 5 of the mold base hook the pull-out shaft 2. Use the reverse rotation of the motor to pull out the mold. After replacing the mold to be used, push it back to the original position. When the mold reaches the designated position, the resistance of the slider 11 increases, and the joint 4 pops up. The operator stops the motor. acting. Lift the pivoting arm 3 to move the slider 11 to the center position, and the forklift picks up the mold changing trolley, and the mold replacement is completed.

The above descriptions are only preferred examples of the present utility model, and are not intended to limit the protection scope of the present utility model. All modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
