Description

Technical Field

[0001] The invention relates to the technical field of bending dies, and in particular to a stamping and bending die for a distributor housing. Background Art

[0002] The housing of a power distribution device usually refers to the housing of an electrical distribution device, and its functions mainly include protection, support and isolation. First, the protection function means that the housing can provide necessary protection for the internal electrical components to prevent damage to the equipment caused by external environmental factors such as dust, water vapor, and mechanical shock; secondly, the support function means that the housing can fix the internal electrical components to prevent them from displacement or damage due to vibration, collision, etc.; finally, the isolation function means that the housing can isolate the internal electrical components from the external environment to prevent people or animals from contacting the live parts to ensure safety.

[0003] Since the bending of the distributor housing requires two 90-degree bends at both ends, and the existing bending molds can only perform one-way bending, bending in different directions requires the housing to be repositioned in the mold for secondary bending. Secondly, since the bent distributor housing will be embedded in the mold, it is not convenient for automatic demolding, and it will be stuck inside, making it difficult to separate easily, which has certain disadvantages. Therefore, a stamping and bending mold for the distributor housing is urgently needed to solve the above problems. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-9 As shown, the present invention has the following specific embodiments.

[0036] Example 1

[0037] A stamping and bending die for a distributor housing, comprising a stamping part I, and further comprising:

[0038] A base 1, the four corners of the top of the base 1 are fixedly connected with vertical rods 11, the other ends of the four vertical rods 11 are commonly fixedly connected with a top plate 12, and the bottom of the top plate 12 is fixedly connected with a stamping cylinder 13;

[0039] The lower molding die 2 is fixedly connected to the top of the base 1, the top of the lower molding die 2 is provided with a first molding groove 21, a second molding groove 22 and a feeding groove 23, and both ends of the bottom of the lower molding die 2 are provided with limiting grooves 24;

[0040] The upper forming die 3 is fixedly connected to the telescopic end of the stamping cylinder 13, and two limiting cavities 31 are provided inside the upper forming die 3;

[0041] A first demoulding mechanism, which is used to push the stamping part 1 out of the die groove of the lower forming die 2;

[0042] The second demoulding mechanism is used to push the stamping part 1 away from the outer surface of the upper forming mold 3.

[0043] In this embodiment, Figure 1 , 7As shown in , 8 and 9, first, the stamping part I to be processed is inserted parallel to the front of the lower molding die 2 into the loading trough 23, and the loading trough 23 can limit the stamping part I to be processed, and then the upper molding die 3 is pushed downward by opening the stamping cylinder 13. The upper molding die 3 cooperates with the lower molding die 2 to extrude and form the stamping part I to be processed in the first molding groove 21 and the second molding groove 22 for two bending forming, and then the upper molding die 3 is pulled upward by the stamping cylinder 13. When the upper molding die 3 and the lower molding die 2 are separated, the first demolding mechanism arranged in the lower molding die 2 can push the stamping part I after molding to separate from the lower molding die 2. At the same time, the second demolding mechanism arranged on the upper molding die 3 can push the stamping part I after molding to separate from the upper molding die 3, so as to facilitate the manual removal of the stamping part I after molding from the lower molding die 2.

[0044] For further explanation of this embodiment, Figure 6 As shown, the upper molding die 3 cooperates with the lower molding die 2 in the process of stamping and forming the stamping part I. First, the upper molding die 3 can extrude the stamping part I into the first molding groove 21 for the first bending forming, and then extrude the stamping part I into the second molding groove 22 for the second bending forming, so as to facilitate the stamping part I to be bent and formed twice in succession, avoid secondary processing, and improve the processing efficiency of the stamping part I.

[0045] Example 2

[0046] The first demoulding mechanism includes a first demoulding push plate 4, which is movably connected to the inside of the first molding groove 21 and the second molding groove 22, and both ends of the bottom of the first demoulding push plate 4 are fixedly connected to the first slide bar 41, and one end of the first slide bar 41 away from the first demoulding push plate 4 is fixedly connected to the first limit block 42, and the first slide bar 41 is connected between the first molding groove 21 and the limit groove 24, and the first slide bar 41 is slidably matched with the lower molding mold 2;

[0047] The first limit block 42 is movably connected to the inside of the limit groove 24, and sliders 421 are fixedly connected to both sides of the first limit block 42. The slide groove 241 opened in the limit groove 24 slides with the slider 421. The top of the first limit block 42 is fixedly connected to the first spring 422, the first spring 422 is sleeved on the first slide rod 41, and the first spring 422 is fixedly connected to the lower molding mold 2.

[0048] In this embodiment, Figure 2 , 3As shown in Figure 7, after the stamping part I is stamped and formed by the lower molding die 2 and the upper molding die 3, the upper molding die 3 is pulled upward by the stamping cylinder 13, so that the upper molding die 3 is slowly separated from the lower molding die 2. In the process of the upper molding die 3 being separated from the lower molding die 2, since the lower molding die 2 is embedded and connected with each other under the stamping of the upper molding die 3, the stamping part I is stamped and formed in the first molding groove 21 and the second molding groove 22. At this time, the first demolding push plate 4 movable inside the lower molding die 2 moves to the bottom of the first molding groove 21. At the same time, the first demoulding push plate 4 pulls the first spring 422 to stretch by the first limit block 42 connected to the first slide bar 41, and the stretched first spring 422 will generate a reverse force. When the upper molding die 3 moves upward to separate from the lower molding die 2, the first demoulding push plate 4 is not squeezed by an external force. The directional force generated by the first spring 422 will pull the first limit block 42 to move upward, and the first limit block 42 pushes the first demoulding push plate 4 to move upward through the first slide bar 41, so that the stamping part I extruded inside the lower molding die 2 can be pushed out.

[0049] As a further implementation of this embodiment, when the slider 421 slides to the highest point of the slide groove 241, the first demolding push plate 4 connected to the first slide rod 41 is flush in the second molding groove 22, and the first spring 422 has a contraction tension, and the tension is greater than the gravity of the first demolding push plate 4.

[0050] In the present embodiment, since the pulling force generated by the contraction of the first spring 422 is greater than the gravity of the first demoulding push plate 4, the first spring 422 pulls the first limit block 42 to support the first demoulding push plate 4 through the first slide rod 41, thereby preventing the first demoulding push plate 4 from automatically falling under the action of gravity. At the same time, the set slide groove 241 can limit the sliding slider 421. When the slide groove 241 slides to the highest point in the slider 421, the first limit block 42 and the first demoulding push plate 4 connected by the first slide rod 41 can be flush in the second molding groove 22, so that the unstamped stamping part I can be placed in the loading groove 23 for limiting.

[0051] Example 3

[0052] The second demoulding mechanism comprises a second demoulding push plate 5, which is symmetrically arranged on both sides of the upper molding mold 3. Both ends of the top of the second demoulding push plate 5 are fixedly connected to a second slide bar 51, and one end of the second slide bar 51 away from the second demoulding push plate 5 is fixedly connected to a second limit block 52, and the top of the second limit block 52 is fixedly connected to a second spring 53;

[0053] The second limit block 52 is movably connected to the inside of the limit cavity 31, and one end of the second spring 53 is fixedly connected to the limit cavity 31. When the second limit block 52 is located at the bottom of the limit cavity 31, the second demoulding push plate 5 is flush with the bottom of the upper molding mold 3.

[0054] In this embodiment, Figure 4 and 5 As shown in Figure 7, after the stamping part I is stamped and formed by the lower molding die 2 and the upper molding die 3, the upper molding die 3 is driven to move upward by the stamping cylinder 13. Since the lower molding die 2 and the upper molding die 3 are embedded in each other for stamping, the second demolding push plates 5 arranged on both sides of the upper molding die 3 will be pressed to move upward, and the second demolding push plates 5 drive the connected second limit blocks 52 to move upward through the second slide rod 51. The second spring 52 can compress the second limit blocks 53, and the compressed second spring 53 will generate a reaction force, so that when the upper molding die 3 moves upward, the reaction force generated by the second spring 53 can push the second demolding push plate 5 to move downward, so that the stamping part I stamped and sleeved on the upper molding die 3 can be squeezed out of the bottom of the upper molding die 3, preventing the stamping part I after stamping from being sleeved on the upper molding die 3 and unable to fall off automatically.
