Description

Technical Field

[0001] The utility model relates to the technical field of stamping die manufacturing, in particular to a stamping forming device for a metal cover. Background Art

[0002] Stamping refers to a processing method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. In the early days, the stamping machine was operated by operators through hand or foot operation. The operation process was cumbersome and dangerous. It was mainly used to process simple metal parts with low production efficiency. The finished product obtained by stamping has high structural strength, stable detection accuracy, safety and reliability. Nowadays, stamping technology is widely used and is often used in many fields such as automobile manufacturing, home appliance manufacturing and digital electronics.

[0003] The document with publication number CN111283064A discloses a stamping die that is easy to clean, including two lower stamping dies, multiple upper stamping dies and a base, wherein the upper end of the base is fixedly connected with two vertical plates, a horizontal plate is fixedly connected between the two vertical plates, a first through hole that is connected up and down is provided on the horizontal plate, and a rotating mechanism is rotatably provided in the first through hole, the lower end of the rotating mechanism is fixedly connected with the connecting mechanism, the upper end of the connecting mechanism is fixedly connected with the lower end of the horizontal plate, multiple upper stamping dies are fixedly connected to the lower end of the connecting mechanism, a supporting mechanism is rotatably connected between the two vertical plates, two lower stamping dies are fixedly connected to the upper end of the supporting mechanism, the lower stamping die is located directly below the upper stamping die, a transmission mechanism and a fixing mechanism are provided on the side wall of one of the vertical plates, the transmission mechanism is transmission-connected to the supporting mechanism, and the lower end of the fixing mechanism is movably connected to the transmission mechanism.

[0004] This model is not only convenient for cleaning the stamping die, but also convenient for improving the efficiency of stamping. However, it does not consider the impact of impurities on the stamping die and subsequent stamping products during the stamping process. During the stamping process, each stamping will cause a certain degree of loss to the die. In long-term work, each impact of stamping on the die is normal loss. Regular maintenance and maintenance of the die, timely cleaning of dirt and residues on the die surface, and keeping the die clean and intact can ensure the service life and quality of the die. It also ensures the quality of the products produced by the die. However, if the surface energy of the stamping material is too large, the material may be stuck on the die during the stamping process, resulting in abnormal loss of the die. If the die is damaged during the peeling process of the cover body, it needs to be repaired or replaced, which greatly affects the normal life of the stamping die. In addition, the presence of impurities on the surface of the material will also cause the die to cause additional damage or wear during the long-term stamping process, destroying the smoothness and precision of the die surface, resulting in an abnormal decline in the quality of the die, shortening the service life of the die, and causing the quality of the finished products produced by the stamping of this die to be reduced to varying degrees. Utility Model Content

[0005] In view of the technical defects existing in the background technology, the utility model proposes a stamping forming device for a metal cover body, which solves the technical problem that due to impurities and surface energy on the surface of the material, the mold produces abnormal wear and tear during long-term stamping work, resulting in reduced product quality, and meets the actual needs. The specific technical solution is as follows:

[0006] A stamping forming device for a metal cover, comprising a stamping assembly, a conveyor belt, a clamping device and a forming table, and also comprising a cleaning device, wherein the conveyor belt is arranged at one end of the forming table, the stamping assembly is divided into an upper die assembly and a lower die assembly, the stamping assembly is arranged at the other end of the forming table and the lower die assembly and the conveyor belt are arranged at the same horizontal position, the upper die assembly is arranged at the upper end of the forming table and is perpendicular to the lower die assembly in the vertical direction, the clamping device is arranged at the outer end of the forming table facing the stamping assembly and is at the same horizontal position as the lower die assembly, the cleaning device comprises a dust removal device and a spray cleaning device, the conveyor belt is divided into two sections and is arranged on the forming table, a groove is provided in the middle gap portion of the two sections of the conveyor belt, the dust removal device is arranged in the groove and is parallel to the conveyor belt, and the spray cleaning device is arranged at the upper end of the forming table and is perpendicular to the dust removal device in the vertical direction.

[0007] Furthermore, a dust removal device connecting portion is provided at the bottom of the dust removal device, and the dust removal device is connected to the groove by plugging and unplugging through the dust removal device connecting portion.

[0008] Furthermore, a spray device connection portion is provided at the bottom of the spray device, and the spray device is connected to the upper end of the forming table by plugging and unplugging through the spray device connection portion.

[0009] Furthermore, the dust removal device and the spray cleaning device are both disassembled components, and the dust removal device and the spray cleaning device are respectively arranged in the groove and the upper end of the forming table through a connecting part, or respectively arranged at the upper end of the forming table and the groove.

[0010] Furthermore, the clamping device includes a threaded connection part, a rebound spring, a clamping clamp and a control line. The control line is connected to an external system and controls the clamping of the head clamping clamp. The clamping surface of the clamping clamp is a serrated plane, and a rebound spring is provided in the middle of the clamping clamp.

[0011] Furthermore, a rotary conveyor belt is provided at the outer end of the forming table, and the threaded connection portion is provided in the rotary conveyor belt and moves horizontally at the outer end of the forming table.

[0012] Furthermore, the forming table has a connecting portion, and the stamping assembly and the conveyor belt are respectively arranged on two sides of the connecting portion of the forming table.

[0013] The beneficial effect of the utility model is that the cleaning device is divided into two devices, a dust removal device and a spray cleaning device, which clean both sides of the material respectively, so as to avoid the surface energy of the stamping material being increased due to impurities, so that the stamping material and the lower die assembly are not stuck or stuck together, and the material may fall off during the stamping process due to the presence of release agents on both sides of the material. Through a simple structure, the double-sided cleaning of the stamping material can be completed at a low cost, ensuring that the material can be separated from the mold as smoothly as possible after processing, reducing the possibility of the material getting stuck in the mold, and further avoiding abnormal loss of mold quality due to this phenomenon. Similarly, it avoids other abnormal losses of the mold due to the presence of impurities during long-term stamping work. This abnormal loss will cause the quality of the finished product to decrease in the subsequent stamping process. Through the setting of this structure, the stamping material can be cleaned on both sides, which to a certain extent avoids the mold being stuck due to material and abnormal loss due to the presence of impurities during long-term stamping work, resulting in problems with the quality of subsequent products. The service life of the mold is extended, and the possibility of further damage to the mold when peeling or prying the material due to the stamping material getting stuck in the mold is reduced. At the same time, it also reduces the tedious content of quality inspection that must be carried out after the material gets stuck in the mold. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. It should be pointed out that the following relevant embodiments are only preferred embodiments for better illustrating the present invention itself, and the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technical personnel in this technical field.

[0021] See also Figures 1 to 4 As shown, the utility model provides a stamping forming device for a metal cover, comprising a stamping assembly 1, a conveyor belt 3, a clamping device 4 and a forming table 5, and also comprising a cleaning device, wherein the conveyor belt 3 is arranged at one end of the forming table 5, the stamping assembly 1 is divided into an upper die assembly 101 and a lower die assembly 102, the stamping assembly 1 is arranged at the other end of the forming table 5 and the lower die assembly 102 and the conveyor belt 3 are arranged at the same horizontal position, the upper die assembly 101 is arranged at the upper end of the forming table 5 and is perpendicular to the lower die assembly 102 in the vertical direction, the clamping device 4 is arranged at the outer end of the forming table 5 facing the stamping assembly 1 and is at the same horizontal position as the lower die assembly 102, the cleaning device comprises a dust removal device 7 and a spray cleaning device 6, the conveyor belt 3 is divided into two sections and is arranged on the forming table 5, and the middle gap part of the two sections of the conveyor belt 3 is provided with a groove 301, the dust removal device 7 is arranged in the groove 301 and is parallel to the conveyor belt 3, and the spray cleaning device 6 is arranged at the upper end of the forming table 5 and is perpendicular to the dust removal device 7 in the vertical direction.

[0022] In one case of the present embodiment, the conveyor belt 3 is divided into two parts, a groove 301 is provided between the two conveyor belts 3, and the conveyor belt 3 is installed on the forming table 5. The forming table 5 presents an I-shaped structure, and a connecting part 2 is provided at the upper end of the forming table 5, which can be connected with other devices through the connecting part 2.

[0023] In this embodiment, the cleaning device is divided into a spraying device 6 and a dust removal device 7. The spraying device 6 is connected to the upper end of the forming table 5 through the spraying device connection part 602. The connection method of the spraying device 6 is a plug-in connection. The spraying device 6 can be taken down from the upper end of the forming table 5 by manual operation, and the lubricant and the mold release agent are flowed downward through the nozzle 601 on the spraying device 6 to spray on the upper surface of the stamping material. The dust removal device 7 is arranged in the groove 301 part between the conveyor belts 3, and is connected to the bottom of the forming table 5 through the dust removal device connection part 702. The main connection method is the same as the connection method between the spraying device 6 and the forming table 5, both of which are plug-in connections. The dust removal device 7 can also be taken out from the groove 301 at any time by manual operation. The overall height of the dust removal device 7 is the height including the dust removal brush 701, and the whole is parallel to the conveyor belt 3, thereby avoiding problems in the transportation process of the stamping materials due to the height difference. In this embodiment, the connection between the forming table 5 and the cleaning device is selected as a plug-in connection. The plug-in connection has high reliability and stability, and is very convenient in installation and disassembly. It is very suitable for the connection between the device and the forming table connection part 2. There are also other optional connection methods, such as threaded connection, rivet connection, etc., as long as the cleaning device can be connected to the forming table 5 and has stability and can operate normally.

[0024] The width of the groove 301 is controlled by moving the two ends of the conveyor belt 3 to avoid the situation where the groove 301 is too large and the effective area of ​​the dust removal device 7 is too wide, resulting in the area of ​​the dust removal device 7 being larger than the area of ​​the stamping material, causing the stamping material to accumulate on the surface of the dust removal device 7 and affecting work efficiency.

[0025] The dust removal device 7 is arranged above the groove 301, and the dust removal device 7 is connected to an external energy source to realize the operation of the dust removal device 7. A dust removal brush 701 is arranged on the top of the dust removal device 7, and the dust removal brush 701 rotates at a high speed under the drive of the external energy source. The dust removal brush 701 sweeps away impurities on the lower surface of the stamping material by high-speed rotation, and sweeps the impurities on the lower surface of the stamping material out of the conveyor belt 3, thereby completing the cleaning of the lower surface of the stamping material. The upper surface is provided with a spray device 6 to spray a release agent or a lubricant through a nozzle 601, and completes the comprehensive cleaning of the stamping material together with the dust removal device 7. At the same time, the pressure on the upper surface of the stamping material can increase the contact pressure between the lower surface and the dust removal device 7, so as to prevent the stamping material from being weak. When the stamping material is subjected to the pressure of the spray device 6 or the dust removal device 7, the material position will change due to pressure, thereby affecting the processing procedure.

[0026] The spray device 6 and the dust removal device 7 are assembled by disassembling the connecting parts and exchanging their positions, so that the spray device 6 is installed in the groove 301 and the dust removal device 7 is installed on the upper end of the forming table 5. However, such an assembly scheme is likely to cause the stamping material to be unstable in the subsequent stamping. Therefore, it is the best implementation scheme to install the spray device 6 above the material, on the upper end of the forming table 5, and the dust removal device 7 below the conveyor belt 3.

[0027] The same implementation scheme can also be selected, that is, dust removal devices 7 or spray cleaning devices 6 are set up on the upper and lower surfaces of the stamping material. If the former scheme is adopted, dust removal devices 7 are set up on the upper end of the forming table 5 and in the groove 301, and the technical effect achieved is not as good as setting up a spray cleaning device 6 above the forming table 5 and a dust removal device 7 in the groove 301. If the latter scheme is selected, spray cleaning devices 6 are selected on the upper end of the forming table 5 and in the groove 301, then the upper and lower surfaces of the stamping material will be covered with lubricant and release agent. The stamping material with release agent on both the upper and lower surfaces will lead to a reduction in its own friction, which is inconvenient for the subsequent clamping device 4 to clamp, and is more likely to increase the friction of the stamping material during the stamping process, resulting in deformation of the position of the stamping material under uneven force, or flying out, resulting in defective products and affecting the entire work process.

[0028] The material cleaned on both sides by the spray cleaning device 6 and the dust removal device 7 reduces the residual impurities as much as possible. The presence of impurities will not only greatly increase the possibility of the stamping material getting stuck in the upper die assembly 101 and the lower die assembly 102, but more importantly, the stamping material getting stuck in the stamping assembly 1 will cause abnormal wear and tear on the stamping assembly 1, shortening the service life of the stamping assembly 1. On the other hand, the situation where the stamping material gets stuck in the upper die assembly 101 and the lower die assembly 102 did not occur, but because of the presence of impurities, each stamping will cause abnormal wear and tear on the stamping assembly 1. Although such wear and tear is very slight, it will greatly shorten the service life of the stamping assembly 1 in a long-term work process. The shortened service life of the stamping assembly 1 also means a reduction in the quality of the stamping assembly 1. Whether it is the jamming of the stamping material and the stamping assembly 1, or the presence of impurities in a long-term stamping work, it will cause abnormal wear and tear on the upper die assembly 101 and the lower die assembly 102 in the stamping assembly 1. The quality of the finished product produced by such abnormal wear and tear of the stamping assembly 1 will also be reduced.

[0029] The stamping material cleaned by the cleaning device is transported to the subsequent processing procedure under the action of the conveyor belt 3. The outer end of the forming table 5 is provided with a protruding part, and a rotary conveyor belt 8 is set on the outer end. A threaded connection part 401 is set at the tail of the clamping device 4, and the threaded connection part 401 is clamped on the rotary conveyor belt 8. The tail of the clamping device 4 is connected to the external system through the control line 404. The control line 404 can be used to control the transportation of the clamping device 4 on the rotary conveyor belt 8 and the operation of the clamping clamp 403. Similarly, the clamping device 4 can also be pre-input, so that the clamping device 4 can run on the rotary conveyor belt 8 according to the set program and control the clamping clamp 403 to complete the transportation.

[0030] The clamping device 4 is divided into a threaded connection part 401 at the tail, a clamping clamp 403 at the head, a middle clamping drive shaft 405 and a control line 404 connected to an external system. A rebound spring 402 is provided in the middle of the clamping clamp 403. The clamping drive shaft 405 is composed of two upper and lower shafts respectively connected to the clamping clamp 403. The control line 404 is also connected to the upper and lower shafts of the clamping drive shaft 405 respectively. The external system connected to the control line 404 can directly control the rotation of the clamping drive shaft 405 through the external system. The clamping part of the clamping clamp 403 The concave-convex surface is also provided with serrations, which increases the friction between the stamping materials and the stamping materials without affecting the stamping materials, so as to facilitate the transportation of the stamping materials by the clamping device 4. The tail end of the clamping clamp 403 is connected to the clamping drive shaft 405, and the clamping drive shaft 405 is controlled by the control line 404 to be able to rotate up and down to a certain extent. When there is no subsequent input control signal from the control line 404, the clamping clamp 403 is restored to its original state by the elastic force of the rebound spring 402, and the clamped stamping materials fall to the predetermined position.

[0031] In the present invention, the rotary conveyor belt 8 is consistent with the rotary conveyor belt structure used in the assembly line processing equipment in the prior art. Specifically, the rotary conveyor belt 8 structure is composed of at least pulleys at both ends and a conveyor belt structure connecting the pulleys at both ends, and the conveyor belt generally includes a flexible conveyor belt and a rigid conveyor belt. The conveyor belt used in the same working environment as the present invention is usually a rigid conveyor belt that is convenient for installing a robot arm. The threaded connection part 401 of the clamping device 4 is installed on the segment of the rigid conveyor belt, and moves with the advancement of the rigid conveyor belt, and moves the bottle cap clamping from the stamping station to the spray washing device 6 station along the process sequence, and repeats the above action back and forth continuously in the circular motion of the rigid conveyor belt. Since the composition of the above-mentioned conveyor belt structure is basically the same as that of the prior art, and its adaptive installation method can be adaptively set by technical personnel in this field according to actual needs, the further composition of the rotary conveyor belt 8 structure and the specific setting method of the present invention will not be elaborated here.

[0032] In the stamping part, the stamping assembly 1 is divided into an upper die assembly 101 and a lower die assembly 102. The clamping device 4 moves the stamping material cleaned by the cleaning device to the stamping part of the forming table 5 through the movement of the rotary conveyor belt 8. The clamping clamp 403 places the stamping material above the lower die assembly 102, and the upper die assembly 101 moves downward under hydraulic pressure to complete the stamping of the mold to obtain the required object. After the stamping is completed, the object can be taken out by the clamping device 4. The start switch of the stamping assembly 1 can also be controlled to manually take out the stamped object and transport it to the next process.

[0033] The edge portion of the forming table 5 is provided with a detachable connecting portion 2, through which two forming tables 5 can be connected together to form a new whole, which can facilitate the installation of other devices and avoid the placement of the forming table 5 becoming a problem due to the structural size of the forming table 5 itself.

[0034] In the embodiments, see Figure 5 As shown, another optional clamp is a telescopic clamping device 9, which has a stretchable telescopic rod 901 and a telescopic connecting rod 902 driven by the telescopic rod 901. The telescopic connecting rod 902 is stretched backward to clamp the telescopic clamp 903, so as to clamp the material and achieve the purpose of material transportation. By adding a driving device after the telescopic rod 901, the driving device can control the stretching of the telescopic rod 901 to complete the clamping and releasing of the material. The telescopic clamping device 9 can also be connected to the rotary conveyor belt 8, and the telescopic rod 901 is continuously and repeatedly stretched during the circulating motion of the conveyor belt. The optional connection method can be selected according to actual needs, as long as the telescopic clamping device 9 can be stably connected to the rotary conveyor belt 8.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
