[0063] 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.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0066] With the development of the manufacturing industry, the requirements for product component assembly are getting higher and higher, and the demand for product quality and shipment volume is also increasing day by day. In order to meet the various process requirements of the market for products and improve production efficiency, we are required not only to master the relevant process technology, but also to scientifically and rationally layout its process route, avoid unnecessary waste in the intermediate process, and then make the best use of the shortest time and the least resources to achieve efficient and low-cost production.

[0067] In view of this, the present invention provides a pressure processing device for processing a combined product, wherein the combined product is a finished product obtained by sequentially combining a main part and a plurality of separate parts. Figures 1 to 9 This is an embodiment of the pressure processing equipment provided by the present invention.

[0068] It should be noted that the pressure processing equipment 100 can be a cold pressing processing equipment or a hot pressing processing equipment, and there is no limitation here.

[0069] Please refer to Figure 1 , Figure 2 and Figure 6 The pressure processing equipment 100 includes a machine base 1, multiple pressure processing components 2, a first driving mechanism 3 and a second driving mechanism 4. The machine base 1 has multiple processing stations 1a arranged along its circumference. Each of the pressure processing components 2 includes a holding part 21 and a pressing part 22 arranged in the up-down direction. The pressing parts 22 of the multiple pressure processing components 2 are arranged corresponding to the multiple processing stations 1a. One of the holding parts 21 and the pressing parts 22 has a movable stroke in the up-down direction, wherein each of the holding parts 21 is movably arranged in the circumference of the machine base 1 so that the multiple holding parts 21 can correspond to the multiple pressing parts 22 at different positions. The first driving mechanism 3 is used to drive the holding parts 21 or the pressing parts 22 that are movably arranged in the multiple pressure processing groups to move up and down, and the second driving mechanism 4 is used to drive the holding parts 21 of the multiple pressure processing components 2 to move along the circumference of the machine base 1.

[0070] In the technical solution of the present invention, the relative movement of each of the holding parts 21 and each of the pressing parts 22 is driven by the first driving mechanism 3 to realize the fitting and separation actions. At each processing station 1a, the holding part 21 and the pressing part 22 are fitted to combine the main part placed on the holding part 21 and the split part placed on the pressing part 22 into one, and the combined parts are maintained on the holding part 21. Then, under the action of the second driving mechanism 4, the multiple holding parts 21 are made to rotate synchronously with the parts with different degrees of assembly, so that a single main part can pass through multiple processing stations 1a in turn and be assembled with a corresponding number of split parts to obtain a finished part. With this arrangement, multiple pressure processing steps can be completed by relying on only one device, which simplifies the transportation of circulation tooling and saves space, transportation actions and transportation time. At the same time, each of the holding parts 21 is driven to rotate synchronously, and the transfer process has good consistency. Through structural design, each of the multiple holding parts 21 can correspond to the multiple pressing parts 22 at different positions, so that different assembly processes of the product can be carried out synchronously, thereby improving production efficiency. During the production process, the product only needs to be loaded once, avoiding the cumulative error caused by multiple clamping and positioning.

[0071] In this embodiment, the structures of the plurality of holders 21 are designed to be the same, and each of the holders and each of the pressing parts are combined to form a pressure processing mold.

[0072] It should be noted that the number of the processing stations 1a can be reasonably designed according to the actual structure of the product, so as to design the single rotation angle of the holding part 21 accordingly. For example, four processing stations 1a are arranged in the present embodiment, corresponding to four pressure processing components 2. Therefore, when the second driving mechanism 4 drives to rotate, the multiple holding parts 21 rotate 90° synchronously at a time. When only three processing stations 1a are arranged, the multiple holding parts 21 are adjusted to rotate 120° synchronously at a time. It can be understood that it is necessary to ensure that each of the holding parts 21 has a rotation stroke of 360°. The disassembly of the finished parts can be carried out at the first station, and the finished parts are removed to complete a processing cycle, and then new materials are added. It can also be carried out at the last station on the circumference, and the finished parts are removed and driven to rotate back to the first station to complete a processing cycle.

[0073] The present invention does not limit the specific form of the first driving mechanism 3. In this embodiment, the multiple pressing parts 22 are fixed on the base 1, and the first driving mechanism 3 is two relatively arranged cylinders. The multiple holding parts 21 are all installed through a common top plate. The extension and retraction of the two cylinders drive the lifting and lowering of the top plate, so that the multiple holding parts 21 move up and down to separate or fit with the corresponding pressing parts 22. In another embodiment, the multiple holding parts 21 are arranged on the base 1 and only have a rotation stroke. At this time, the first driving mechanism 3 can be designed as a scissors lifting mechanism, and the multiple pressing parts 22 are installed through a common bottom plate. The multiple pressing parts 22 and the multiple holding parts 21 are actively coordinated by driving the lifting and lowering of the bottom plate.

[0074] The present invention does not limit the specific form of the second driving mechanism 4, which can be realized by belt and pulley transmission, or by motor direct drive. In this embodiment, the plurality of pressing parts 22 are fixed on the machine base 1, and the first driving mechanism 3 is used to drive each of the holding parts 21 to move. Specifically, the second driving mechanism 4 includes a driving motor 41 and a rotating disk 42. The driving motor 41 is fixed to the machine base 1. The driving motor 41 has a driving shaft extending in the vertical direction. The driving shaft is coaxially provided with a first gear. The rotating disk 42 can move in the vertical direction and rotate along the axis extending in the vertical direction. The rotating disk 42 is provided with matching teeth meshing with the first gear so as to rotate under the drive of the driving motor 41. The plurality of holding parts 21 are arranged at the lower end of the rotating disk 42, and the first driving mechanism 3 is connected to the rotating disk 42 to drive the rotating disk 42 to move in the vertical direction. Taking the overall spatial arrangement into consideration, the driving shaft of the driving motor 41 is not coaxially arranged with the center of the rotating disk 42. The driving force is transmitted by the cooperation between the first gear and the mating tooth, thereby realizing the rotation of the rotating disk 42. Since the multiple holding parts 21 are all arranged on the rotating disk 42, synchronous rotation can be realized, and the arrangement of the first driving mechanism 3 is convenient. At this time, when the first driving mechanism 3 drives the rotating disk 42 to rise and fall, the driving motor 41 follows the synchronous rise and fall. Specifically, the present invention does not limit the specific position of the mating tooth. In one embodiment, a circular hole can be arranged at the center of the upper end surface of the rotating disk 42, and internal teeth are arranged on the inner wall surface of the circular hole to form the mating teeth. In another embodiment, external teeth can be arranged on the peripheral side surface of the rotating disk 42 to form the mating teeth. In this embodiment, a frustum is arranged on the upper end surface of the rotating disk 42, and external teeth are arranged on the peripheral side surface of the frustum to form the mating teeth, thereby facilitating the spatial arrangement between the devices.

[0075] It should be noted that, in this embodiment, the first driving mechanism 3 can be implemented by setting a screw lifting mechanism or a cylinder. In other embodiments, the first driving mechanism 3 is arranged on the rotating disk 42 to drive the multiple holding parts 21 to move respectively in the up and down directions. At this time, the second driving mechanism 4 may include multiple screw mechanisms, which are respectively arranged corresponding to the multiple holding parts 21, and are arranged between the rotating disk 42 and the multiple holding parts 21. By controlling the multiple screw mechanisms to realize the movement of the multiple holding parts 21, the multiple holding parts 21 can be designed to open in sequence, or to open synchronously. It can be reasonably designed according to the specific requirements of each pressure processing step of the product. At this time, when each of the holding parts 21 is lifted or lowered, the rotating disk 42 and the driving motor 41 are not lifted or lowered synchronously.

[0076] In the mold design, taking into account the errors caused by the accuracy of the equipment and the processing accuracy, a floating mechanism is set in each of the holding parts 21, or a floating mechanism is set between each of the holding parts 21 and the rotating disk 42, allowing the first mounting seat 211 to have a certain degree of flexibility and adaptability, and can be deflected within the plane to ensure the mold clamping accuracy. In one embodiment, multiple ones are set, each of which passes through the first mounting seat 211 and is fixed to the component above it, and a first floating gap is set between the outer surface of each positioning member and the inner wall surface of the corresponding hole on the first mounting seat 211, and a second floating gap is set between the upper end of each positioning member and the first mounting seat 211. The floating degree is controlled by limiting the sizes of the first floating gap and the second floating gap to achieve accurate positioning.

[0077] During the entire processing process, it is necessary to ensure that the product is held on the holding part 21 each time it rotates, so that it can flow between the multiple processing stations 1a. To this end, in the present invention, each of the holding parts 21 includes a first mounting seat 211 provided on the machine base 1 and a clamping structure provided on the first mounting seat 211. The clamping structure is used to fix the parts to be processed, and the first mounting seat 211 is drivingly connected to the second driving mechanism 4. The product is held on the holding part 21 by the clamping structure. Specifically, the present invention does not limit the specific form of the clamping structure. In one embodiment, the clamping structure can be a vacuum suction cup, and the parts are adsorbed and released by vacuum adsorption. In other embodiments, the clamping structure is a magnetic suction cup. The clamping structure is mainly aimed at the case where the product is a metal part, and can be fixed by magnetic attraction, and adsorption and release are achieved by turning on and off the current of the electromagnet.

[0078] Considering that some products require cold pressing or hot pressing, temperature control is required at this time, and the magnetic suction cup and vacuum suction cup may be difficult to set up. In this embodiment, please refer to Figures 2 to 4, the clamping structure includes at least two movable blocks 2121, the two movable blocks 2121 are arranged on the lower end surface of the first mounting seat 211, and have a movable stroke that approaches or moves away from each other, and the opposite end surfaces of the two movable blocks 2121 are used to jointly clamp the parts to be processed. At this time, the product is fixed by a mechanical clamping structure. When loading, the two movable blocks 2121 are driven away from each other. After the product is placed, the two movable blocks 2121 are driven close to each other to clamp together. It should be noted that, considering that some products need to attach the split parts to the lower end surface of the main part during the production process, it is necessary to keep the lower end surface of the subject part smooth, dust-free, and free of fingerprints. Therefore, the opposite end surfaces of the two movable blocks 2121 are respectively tightly matched with the peripheral side surfaces of the subject part to achieve clamping and fixation.

[0079] Further, in order to realize the automatic reciprocating motion of the two movable blocks 2121, please refer to Figure 3 to Figure 4 In one embodiment, at least two grooves are correspondingly provided on the lower end surface of the first mounting seat 211, and the two movable blocks 2121 are movably installed in the two grooves respectively. The opposite ends of the two movable blocks 2121 are arranged to protrude downward from the corresponding grooves, and a first spring 213 is provided between the opposite ends of the two movable blocks 2121 and the side walls of the corresponding grooves. Under the elastic force of the first spring 213, the two movable blocks 2121 can be kept in a tensioned state when clamping the main parts, so that the clamping force can be guaranteed. When the product needs to be released, the first spring 213 is compressed to make the two movable blocks 2121 move away from each other. When the control of the first spring 213 is released again, the two first springs 213 can drive the two movable blocks 2121 to rebound automatically. The structure is simple and the setting is convenient.

[0080] It should be noted that the spring can be compressed by the movable block 2121 manually by an external robotic arm or an operator to load the main parts. For convenience, in this embodiment, the lower end surface of each movable block 2121 is penetrated by a first through hole, and the lower end surface of the first mounting seat 211 is provided with two mounting grooves 2111 corresponding to the two movable blocks 2121. The clamping structure also includes at least two locking blocks 2122, and each locking block 2122 is movably installed in the corresponding mounting groove 2111 along the up and down directions, and has an open position extending downward into the corresponding first through hole, and a locked position separated from the first through hole upward. With such arrangement, blocking and avoiding of each movable block 2121 can be achieved by changing the position of the locking block 2122. When the locking block 2122 is in the locking position, that is, it is clamped in the first through hole, the first spring 213 is compressed, and the positions of the two movable blocks 2121 are limited to be separated. When the locking block 2122 is in the open position, that is, it is completely received in the installation groove 2111 to avoid the first through hole, the first spring 213 naturally extends, and the positions of the two movable blocks 2121 are controlled to be limited to a clamping state.

[0081] Based on the above embodiment, the upper end of each locking block 2122 is connected to the upper wall of the corresponding installation groove 2111 through the second spring 214. In the natural state, the two locking blocks 2122 protrude from the installation groove 2111 and extend into the first through hole under the action of elastic force, keeping the two movable blocks 2121 in a separated position. At this time, the main part is loaded. After the positions are corresponding, the two locking blocks 2122 are pushed to press the second spring 214 until the locking blocks 2122 are completely retracted into the installation groove 2111. At this time, the two movable blocks 2121 automatically pop open, and the notch of the installation groove 2111 is blocked by the movable block 2121 whose position has changed, so that the locking block 2122 cannot extend, and the two movable blocks 2121 are kept in a clamped state to fix the main part.

[0082] In order to facilitate the loading of the main parts, in one embodiment, please refer to Figure 5One of the multiple processing stations 1a is a loading station 1b. The pressure processing equipment 100 also includes a loading component 23. The loading component 23 includes a support seat 231 and at least two push rods 232. The support seat 231 is spaced apart from the machine base 1, and has a movable stroke close to or away from the loading station 1b. It can be controlled by a robot or manually controlled by an operator. A mounting position is provided in the middle of the support seat 231 for placing parts to be processed. The two push rods 232 are provided on the support seat 231 and are located at the periphery of the mounting position. Each of the push rods 232 can be driven by the support seat 231 to contact the corresponding locking block 2122, thereby pushing the locking block 2122 to move from the locking position to the opening position. When in use, the support seat 231 is moved to the bottom of the holding part 21, and then the support seat 231 is driven to move upward. The two push rods 232 first contact the two locking blocks 2122 to push them to move. At this time, the push rod 232 is placed in the first through hole, and the locking block 2122 retracts into the mounting groove 2111. When the main part reaches the specified position, the position of the main part is maintained and the support seat 231 is moved downward, so that the push rod 232 gradually disengages from the first through hole, and the two movable blocks 2121 move a certain distance to block the locking block 2122 from rebounding. When the push rod 232 completely disengages from the first through hole, the two movable blocks 2121 clamp the main part. It should be noted that the upper end of each of the push rods 232 can be set at an angle to ensure that the diameter of the top end is smaller than the diameter of the bottom end, or the upper end of each of the push rods 232 can be set in two sections that decrease in size in sequence, thereby ensuring that during the downward movement of the push rods 232, the two movable blocks 2121 move a certain distance to prevent the locking block 2122 from rebounding.

[0083] It should be noted that, in the present embodiment, four movable blocks 2121 are provided and are evenly arranged along the circumference of the first mounting seat 211 . Correspondingly, four locking blocks 2122 are provided and four push rods 232 are provided.

[0084] In addition, the pressure processing equipment 100 also includes a loading assembly 23 spaced apart from the machine base 1, and the loading assembly 23 includes a loading part 233, and the loading part 233 has a movable stroke close to or away from the loading station 1b, and is used to transfer the parts to be processed to the holding part 21 located at the loading station 1b. In this embodiment, the loading part 233 is configured as a pneumatic finger, which can be directly purchased to meet the use requirements. At the same time, the pneumatic finger is positioned by the peripheral side of the main part, which can ensure the cleanliness of the lower end surface of the main part.

[0085] Furthermore, after the finished parts are processed, the finished parts can be directly taken out when they are in the holding part 21, that is, taken out from above. In this embodiment, one of the processing stations 1a is a taking-out station 1c, and the pressure processing assembly 2 arranged on the taking-out station 1c also includes a blanking portion 25, which can transfer the finished parts from the holding part 21 to the pressing part 22 when the holding part 21 and the pressing part 22 of the pressure processing assembly 2 are separated. In this way, the finished parts are transferred to the pressing part 22, which is convenient for the operator to operate. When the clamping structure is as described above, the blanking portion 25 is set to be the same structure as the ejector 232. When the clamping structure is other structures, the blanking portion 25 can be a vacuum suction cup or an electromagnetic suction cup, which is not limited here.

[0086] Different specifications of products and different incoming materials result in different thicknesses of main parts and / or split parts. A fixed mold distance may cause damage to the product. For this reason, in the present invention, each of the pressing parts 22 includes a second mounting seat 221 and a mold core structure. The second mounting seat 221 is fixed to the machine base 1, and the mold core structure is elastically mounted to the second mounting seat 221 along the up and down directions. The upper end surface of the mold core structure is used for placing parts to be processed, so that when the holding part 21 is in close contact with the mold core structure, the mold core structure is allowed to automatically move a certain distance and perform high self-adaptation, thereby achieving a good matching effect.

[0087] According to the different structural features of the split parts, different mold core structures are set accordingly for matching. In one embodiment, please refer to Figure 8 The mold core structure includes a first mold core 2221 and at least one compression spring, the compression spring is arranged between the first mold core 2221 and the second mounting seat 221, and the upper end surface of the first mold core 2221 is used for placing the parts to be processed. The first mold core 2221 is made of rigid material, and the compression spring is used to achieve a highly adaptive effect when the mold is closed. The compression spring is in contact with the middle part of the lower end surface of the first mold core 2221. It can be understood that the first mold core 2221 should limit its movement direction and movement stroke during the up and down movement, so the design of the equal height screw and the spring matching form is limited. Specifically, the equal height screw limits the stroke of the first mold core 2221, and a spring is sleeved on the outer surface of the equal height screw. The spring is between the first mounting seat 211 and the first mold core 2221, and can also provide elastic support.

[0088] In another embodiment, please refer to Figure 7The first mold core 2221 includes a first hard mold core 2221a and a first soft mold core 2221b disposed at the upper end of the first hard mold core 2221a. The upper end surface of the first soft mold core 2221b is used to place the parts to be processed, and the first hard mold core 2221a is connected to the compression spring. At this time, not only can the first hard mold core 2221a be displaced on the line of action of the compression spring, but the first soft mold core 2221b can be deformed under pressure due to its material characteristics, which can not only adapt to the product, but also provide a certain pressure deformation. When the main parts and the split parts of the bonding platform are assembled, the first soft mold core 2221b is pressed down by pressure and expands and deforms, which can increase the contact area with the split parts and provide a better pressing effect.

[0089] The present invention does not limit the material of the first soft mold core 2221b, which is preferably silicone.

[0090] In yet another embodiment, please refer again to Figure 8 In order to facilitate the loading and positioning of the split parts, the first mold core 2221 also includes an annular mold core 2222 which is sleeved on the outside of the first hard mold core 2221a and the first soft mold core 2221b and can move in the up and down directions. The middle part of the upper end surface of the annular mold core 2222 is used for placing the parts to be processed. The annular mold core 2222 is made of rigid material and can ensure the loading and positioning. Due to its annular setting, it is initially higher than the first soft mold core 2221b to ensure the flatness of the part loading. When the holding part 21 and the pressing part 22 are in contact with each other, they move down to a position lower than the first soft mold core 2221b, so that the parts to be processed are in contact with the upper end of the first soft mold core 2221b. Specifically, a plurality of second through holes are arranged on the annular mold core 2222, which cooperate with a plurality of guide pillars, and equal-height screws and springs are arranged. A spring is sleeved on the outer surface of the equal-height screws. The spring is located between the first mounting seat 211 and the annular mold core 2222, and can also provide elastic support.

[0091] In addition, please refer to Figure 8 An annular positioning groove is provided at the upper end of the annular mold core 2222, and the annular positioning groove is connected to the inner hole of the annular mold core 2222 to form a circumferential positioning surface on the bottom wall of the annular positioning groove for the split parts to be placed and positioned. The periphery of the split parts contacts the side wall of the annular positioning groove to provide circumferential limitation and ensure the stability of assembly.

[0092] In other embodiments, please refer to Figure 7The mold core structure includes a second mold core 2223 disposed on the second mounting seat 221. The second mold core 2223 is made of a flexible material. The upper end surface of the second mold core 2223 is used to place the part to be processed. In this case, there is no need to design a spring. The second mold core 2223 is first compressed and deformed by relying on the material properties of the second mold core 2223.

[0093] Furthermore, considering the flatness of product placement, the mold core structure also includes an annular positioning frame 2224 which is sleeved on the outside of the second mold core 2223 and can move in the up and down directions. A reserved gap is formed between the annular positioning frame 2224 and the second mold core 2223. The reserved gap provides sufficient space for the expansion and deformation of the second mold core 2223. The middle part of the upper end of the annular positioning frame 2224 is used for placing parts to be processed. It is initially set higher than the second mold core 2223 to ensure the flatness of part loading, so that it is set lower than the second mold core 2223 when the holding part 21 and the pressing part 22 are in contact with each other, so that the parts to be processed are in contact with the second mold core 2223.

[0094] In this embodiment, the second mold core 2223 is directly connected. The elastic deformation of the second mold core 2223 is limited and is subject to the mold height reserved by the pressing part 22. In view of this, the second mounting seat 221 includes a first seat plate and an adjustment plate 2211 that can be detachably mounted to the first seat plate. The second mold core 2223 can be detachably mounted to the adjustment plate 2211. In this way, the initial height can be adjusted by replacing the adjustment plate 2211, thereby indirectly controlling the deformation of the second mold core 2223.

[0095] To facilitate the positioning of the mold height, please refer to Figure 2 , Figure 6 and Fig. 9 Each of the pressure processing components 2 also includes a positioning structure, and the positioning structure includes a plurality of first positioning columns 241 and a plurality of second positioning columns 242 that are relatively arranged in the up-down direction. The plurality of first positioning columns 241 are arranged on each of the holding parts 21, and the plurality of second positioning columns 242 are arranged on each of the pressing parts 22. Each of the first positioning columns 241 can be tightly matched with the corresponding second positioning columns 242 after the plurality of holding parts 21 rotate. It can be understood that it is necessary to ensure that the plurality of first positioning columns 241 and the plurality of second positioning columns 242 are evenly distributed, so that after the plurality of holding parts 21 rotate synchronously by a certain angle, when they fall again to cooperate with the pair of pressing parts 22, the first positioning columns 241 that have changed their positions can still be tightly matched with the second positioning columns 242.

[0096] Furthermore, each of the first positioning posts 241 and / or each of the first positioning posts 241 includes a first section, a second section, and a third section sequentially distributed in the up-down direction, the first section and the third section are made of a rigid material, and the second section is made of a heat-insulating material. The second section of the heat-insulating material can prevent heat transfer, and considering that the texture of the heat-insulating material is generally brittle, rigid materials are designed at both ends for protection. In this embodiment, the first section and the second section are both made of steel to extend their service life.

[0097] According to the processing requirements of different products, some products need to be processed in a vacuum confined space. For this purpose, please refer to Fig. 9 The pressure processing equipment 100 further includes a vacuum cover 5, which has a movable stroke along the up and down directions. The vacuum cover 5 and the machine base 1 together enclose a vacuum chamber. The plurality of pressure processing components 2 and the driving device are arranged in the vacuum chamber. The first driving mechanism 3 is connected to the driving wheel of the vacuum cover 5. The first driving mechanism 3 can drive the vacuum cover 5 to rise and fall, thereby creating a vacuum environment when each of the holding parts 21 and each of the pressing parts 22 are attached. The vacuum chamber is connected to a vacuum pump, which is connected to a vacuum tank, and the vacuum chamber is evacuated by controlling the valve on the pipeline.

[0098] It should be noted that, since the purpose of the vacuum hood 5 is to ensure that the processing of parts is carried out in a vacuum environment, the first driving mechanism 3 includes two driving parts, which respectively drive the vacuum hood 5 and the rotating disk 42 to rise and fall. One of the driving parts is a cylinder, which is arranged on the outside of the vacuum hood 5 to drive the vacuum hood 5 to rise and fall. The other driving part is other smaller lifting driving structure, which is arranged inside the vacuum hood and can move synchronously with the rising and falling of the vacuum hood 5.

[0099] Based on the above embodiments, the first driving mechanism 3 often realizes its function through a cylinder, an electric push rod, a hydraulic cylinder, a screw structure or a combination of several of them. Taking the cylinder as an example, the length of its cylinder rod limits the lifting stroke, and in the pressure processing equipment 100, it is necessary to match the combined height of the internal parts and the mold opening height of the holding part 21 and the pressing part 22. Therefore, in one embodiment, the pressure processing equipment 100 also includes an annular matching cover 6, which is arranged on the machine base 1 and is located on the outside of the multiple pressure processing components 2. The upper end of the annular matching cover 6 is fitted with the lower end of the vacuum cover 5 to enclose and form the vacuum chamber, and height compensation is performed through the annular matching cover 6 to achieve a good matching effect.

[0100] In order to ensure the sealing performance, a sealing gasket is arranged between the vacuum cover 5 and the annular matching cover 6. The sealing gasket is arranged in an annular shape, and is matched with the end surface shapes of the vacuum cover 5 and the annular matching cover 6. The sealing gasket can be arranged at the lower end of the vacuum cover 5 or at the upper end of the annular matching cover 6, and both can ensure the sealing effect.

[0101] Taking the arrangement in this embodiment as an example, the finished part consists of a main part and three split parts, the three split parts are divided into split part b, split part c, split part d, and four processing stations 1a are designed, namely station A, station B, station C, and station D, among which station B is the initial processing station 1a, and the order of stations that a single part passes through in one rotation cycle is station B, station C, station D, and station A, among which station B is the loading station 1b, and station A is the taking-out station 1c. The working process of the pressure processing equipment 100 is as follows:

[0102] At the B station, the first main part is installed through the loading assembly 23, and the first main part is clamped by the four movable blocks 2121. At the same time, the split part b is loaded into the pressing part 22, and the multiple holding parts 21 are driven to be pressed down synchronously to close the mold with the multiple pressing parts 22. The vacuum chamber is closed and evacuated, and the multiple holding parts 21 are opened, and the vacuum cover 5 is opened at the same time. At this time, the first main part is connected to the split part b as a whole and placed on the holding part 21. The multiple holding parts 21 are driven to rotate 90° synchronously, and the first main part and the split part b are driven to the C station together.

[0103] At the C station, keep the holding part 21 and the pressing part 22 separated, load the split part c, and at the same time load the second main part and the second split part b at the B station, drive the multiple holding parts 21 to be pressed down synchronously to close the mold with the multiple pressing parts 22, the vacuum cover 5 is closed and evacuated, open the multiple holding parts 21, and open the vacuum cover 5 at the same time. At this time, the first main part, the split part b, and the split part c are connected as one, the second main part and the second split part b at the B station are connected as one, and are all placed on the holding part 21, drive the multiple holding parts 21 to rotate 90° synchronously, and drive the first main part, the split part b, and the split part c to the D station together, and drive the second main part and the second split part b to the C station.

[0104] At station D, the operating steps are the same as those at station C. At this station, the multiple holding parts 21 are opened, and the first main part, split part b, split part c, and split part d are assembled to obtain the first finished part. The processing progress of the remaining stations decreases in sequence, and the multiple holding parts 21 are driven again to rotate 90° synchronously to bring the first finished part to station A.

[0105] At station A, there are no separate parts. It only acts as a compaction action for each finished part to ensure a tight connection. After compaction, the first finished part is clamped open under the action of the unloading part 25. After the multiple holding parts 21 are opened, the first finished part remains on the pressing part 22 and can be taken out.

[0106] At this time, the processing of the first finished part is completed, forming a complete processing cycle. When the multiple holding parts 21 are rotated again, the corresponding split parts can be loaded in each station in turn, and at the same time, a finished part can be taken out at station A.

[0107] It should be noted that the loading of each workstation can be carried out when the holding portion 21 and the pressing portion 22 are separated, or can be carried out after the plurality of holding portions 21 are rotated and before they are closed.

[0108] In other embodiments, depending on the assembly method of the product and the structure of each part, station A may not be set. In this case, the rotating disk 42 is controlled to rotate 120° each time, and the parts are removed after the processing at station C is completed.

[0109] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
