Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping die technology, specifically a safe reciprocating equipment for receiving stacked layers. Background Technology
[0002] When stamping laminations for a motor stator, the falling laminations need to be stacked and arranged along the height direction in the lower channel, supported by positioning blocks inside the channel sidewall. Once the set quantity is reached, the positioning blocks retract, causing the laminations to fall to the designated position. Finally, the positioning blocks extend and reset under the drive of the power mechanism, preparing for the next receiving. This type of equipment has the following drawbacks: Due to the linear telescopic structure of the positioning blocks, i.e., using a rigid connection to support the falling laminations, if the piston rod of the cylinder fails to extend or retract, the laminations will continuously stack excessively, eventually breaking under the pressure of the punch on the press. This also affects the stacked laminations and damages the die, causing production losses and safety hazards. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a safe reciprocating equipment for stacking layers by using a lever-type positioning block, which modifies the original linear motion into a rotational structure, so that the positioning block can swing downward in case of an accident, that is, by using a movable support method to avoid accidental impact and eliminate safety hazards.
[0004] The technical solution of this utility model is to provide a safe receiving and stacking reciprocating device with the following structure: multiple safe receiving components are arranged on the side wall of the material discharge hole of the lower mold base; the multiple safe receiving components are arranged in more than one layer, with multiple safe receiving components in each layer located on the same circumference; each safe receiving component is a lever structure, with the fulcrum located in a channel in the side wall of the lower mold base; each safe receiving component has a set of power mechanisms at its bottom, and in the receiving state, the front end of each safe receiving component extends into the material discharge hole, and the bottom is powered by a power mechanism. The support rods of the mechanism abut against each other to support the material falling during stamping. In the unloading state, the support rod of the power mechanism at the bottom of each safety receiving component retracts, and each safety receiving component swings down into the side wall channel of the lower die base under its own weight, while the material it carries falls to the designated position at the bottom under its own weight. In the overload state, when the material carried exceeds a preset threshold, the support rod of the power mechanism at the bottom of each safety receiving component is squeezed to retract inward, and at the same time, each safety receiving component swings down into the side wall channel of the lower die base while tightly attached to the support rod, and the material it carries falls down.
[0005] The multiple safety receiving components have a double-layer structure. Material is dropped from the upper layer safety receiving component to the lower layer safety receiving component. The lower layer safety receiving component drops material according to the settings, and the material in the upper layer safety receiving component returns to the receiving state to continue receiving material.
[0006] The safety receiving component has a rotating shaft, a bearing surface, and a driving surface. The rotating shaft is rotatably connected to the lower mold base. The bearing surface is located at the top of the safety receiving component, and the driving surface is located at the bottom of the safety receiving component. When the material receiving state is reached, the support rod of the power mechanism extends and pushes the driving surface, thereby making the bearing surface face upward and perpendicular to the material dropping hole.
[0007] The power mechanism includes a cylinder, a slide rod, and a slide rod stop; the cylinder is fixed outside the lower mold base, the lower mold base has a cavity, the slide rod stop is fixed inside the cavity, there are multiple slide rods, all of which are fixed to the slide rod stop, and the ends of the multiple slide rods are fixed to a support rod.
[0008] This utility model also includes a sliding rod positioning device, wherein the multiple sliding rods move through the sliding rod positioning device and their ends are fixed to the support rod, thereby providing radial positioning for the multiple sliding rods and guiding the sliding direction.
[0009] With the above structure, this utility model has the following advantages: By using a lever-type positioning block, the original linear motion is modified into a rotating structure. In the receiving state, the front end of each safety receiving component extends into the material discharge hole, and its bottom is supported by the power mechanism's support rod to bear the material being pressed down. In the discharge state, the support rod of the power mechanism at the bottom of each safety receiving component retracts, and each safety receiving component swings down into the side wall channel of the lower die base under its own weight. The carried material falls to the designated position at the bottom under its own weight. This structure has sufficient strength while meeting the load-bearing requirements. Furthermore, in case of an accident, the positioning block can swing downwards. That is, in an overload state, when the carried material exceeds a preset threshold, the support rod of the power mechanism at the bottom of each safety receiving component is squeezed, causing it to retract inwards. Simultaneously, each safety receiving component swings down tightly against the support rod into the side wall channel of the lower die base, and the carried material falls down. This extreme situation, using a movable support method, avoids accidental impacts and eliminates safety hazards, while also preventing damage to the compression cylinder.
[0010] As an improvement, the multiple safety receiving components are a double-layer structure. Material is dropped from the upper safety receiving component to the lower safety receiving component. The lower safety receiving component drops material according to the settings, and the material in the upper safety receiving component returns to the receiving state to continue receiving material. In case of excessively rapid material dropping, the lower safety receiving component can play a buffering and storage role.
[0011] As an improvement, the safety receiving component is provided with a rotating shaft, a bearing surface, and a driving surface. The rotating shaft is rotatably connected to the lower mold base, the bearing surface is located at the top of the safety receiving component, and the driving surface is located at the bottom of the safety receiving component. When the material receiving state is reached, the support rod of the power mechanism extends and pushes the driving surface, thereby making the bearing surface face upward and perpendicular to the material dropping hole. This safety receiving component has a simple structure, good reliability, and direct drive.
[0012] As an improvement, the power mechanism includes a cylinder, a slide rod, and a slide rod stop; the cylinder is fixed outside the lower mold base, the lower mold base has a cavity, the slide rod stop is fixed inside the cavity, there are multiple slide rods, all of which are fixed to the slide rod stop, and the ends of the multiple slide rods are fixed to the support rod, which has good structural reliability and rapid operation.
[0013] This utility model also includes a sliding rod positioning device, wherein the multiple sliding rods move through the sliding rod positioning device and their ends are fixed to the support rod, thereby providing radial positioning for the multiple sliding rods, allowing the sliding rods to slide in a straight line and preventing swaying.
[0014] As an improvement, multiple safety support components on each layer are evenly distributed along the circumference to ensure balanced load-bearing capacity. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] like Figure 1-7As shown, this utility model discloses a safety-supporting, stacking, reciprocating device, comprising multiple safety support components 1, which are disposed on the side wall of the blanking hole 3 of the lower die base 2. The multiple safety support components 1 are arranged in more than one layer, with the multiple safety support components 1 in each layer located on the circumference at the same height, thereby enabling a set of motor laminations to be supported by multiple safety support components 1 in one layer. The multiple safety support components 1 in each layer are evenly distributed along the circumference.
[0026] Each safety support 1 is a lever structure that allows the fulcrum to rotate. The fulcrum is located in the channel on the side wall of the lower mold base 2.
[0027] like Figure 6 and Figure 7 As shown, the safety receiving component 1 is provided with a rotating shaft 5, a bearing surface 6 and a driving surface 7. The rotating shaft 5 is rotatably connected to the lower mold base 2. The bearing surface 6 is located at the top of the safety receiving component 1, and the driving surface 7 is located at the bottom of the safety receiving component 1. When the material receiving state is reached, the support rod 4 of the power mechanism extends and pushes the driving surface 7, thereby making the bearing surface 6 rise to a state perpendicular to the material dropping hole 3.
[0028] The front end of the support rod 4 has an arc-shaped structure, and the driving surface 7 can also adopt an arc-shaped structure, so that the safety support 1 swings more smoothly.
[0029] Each safety receiving component 1 has a set of power mechanisms at its bottom. The power mechanisms in this embodiment include a cylinder 8, a slide rod 9, and a slide rod stop 10; the cylinder 8 is fixed outside the lower mold base 2, the lower mold base 2 has a cavity 11, the slide rod stop 10 is fixed inside the cavity, there are multiple slide rods 9 and all of them are fixed to the slide rod stop 10, and the ends of the multiple slide rods 9 are fixed to the support rod 4.
[0030] like Figure 2 As shown, this utility model also includes a sliding rod positioning device 12. The multiple sliding rods 9 move through the sliding rod positioning device 12 and their ends are fixed to the support rod 4, which provides radial positioning for the multiple sliding rods 9. The piston rod of the cylinder 9 extends and retracts to drive the extension and retraction of the support rod 4. After extending, it pushes the safety support member 1 to swing upward. After the piston rod retracts, the safety support member 1 swings downward under its own weight.
[0031] In the receiving state, the front end of each safety receiving component 1 extends into the discharge hole 3, and the bottom is supported by the support rod 4 of the power mechanism to bear the material that is being punched down. At this time, because of the presence of the front end of the safety receiving component 1, the material cannot fall normally into the discharge hole 3, and thus they are stacked along the axial direction.
[0032] In the material dropping state, the support rod 4 of the power mechanism at the bottom of each safety receiving component 1 retracts, and each safety receiving component 1 swings down into the side wall channel of the lower mold base 2 under its own weight. At this time, all safety receiving components 1 leave the material dropping hole 3, so that the material being carried falls to the designated position at the bottom under its own weight.
[0033] In an overload state, when the material being carried exceeds a preset threshold, the support rod 4 at the bottom of each safety support 1 is squeezed to retract inward. At the same time, each safety support 1 is pressed tightly against the support rod 4 and swings down into the side wall channel of the lower mold base 2, while the material being carried falls down.
[0034] The multiple safety receiving components 1 have a double-layer structure. Material from the upper safety receiving component 1 is fed to the lower safety receiving component 1, and the lower safety receiving component 1 feeds material according to a set procedure. Meanwhile, the material in the upper safety receiving component 1 returns to its receiving state to continue receiving material. The double-layer or multi-layer structure primarily serves as temporary storage, facilitating the receiving and conveying device below and ensuring that the stamping speed matches the conveying speed.
[0035] There are three implementation methods for the double-layer structure:
[0036] Example 1: As Figure 3 As shown, both the upper safety receiving component 1 and the lower safety receiving component 1 are in the receiving state.
[0037] Example 2: As Figure 4 As shown, the upper safety receiving component 1 is in the unloading state, and the lower safety receiving component 1 is in the receiving state.
[0038] Example 3: As Figure 5 As shown, the upper safety receiving component 1 is in the receiving state, and the lower safety receiving component 1 is in the dropping state.
