Description

Technical Field

[0001] This utility model belongs to the field of hot pressing technology, and in particular relates to a double-inlet double-outlet hot press. Background Technology

[0002] In existing technologies, traditional hot presses typically employ a single-row hot plate structure, resulting in low efficiency. To improve efficiency, double-inlet, double-outlet hot presses have emerged, enabling simultaneous operation from both sides by using two rows of hot plates. However, a vertical partition is required between the left and right side plates of a double-inlet, double-outlet hot press to allow for sliding contact. Since the left and right side plates can exchange heat with the external environment, while the vertical partition cannot, a significant temperature difference exists between the vertical partition and the left and right side plates. This disrupts temperature uniformity during the hot pressing process, affecting product quality. Utility Model Content

[0003] Based on this, and to address the aforementioned technical problems, a double-inlet double-outlet hot press is provided.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A double-inlet, double-outlet hot press includes two active hot press plates for lifting and lowering under the drive of a drive mechanism, two static hot press plates respectively opposite to the two active hot press plates, at least one dynamic hot press unit, and a frame for the dynamic hot press unit to slide up and down. The frame includes two side plates and a vertical partition between the two side plates. Each dynamic hot press unit includes two passive hot press plates. The two passive hot press plates slide up and down with the vertical partition and the corresponding side plates and are located between the corresponding active hot press plate and the static hot press plate. The vertical partition has a cooling system for uniformly cooling the vertical partition.

[0006] This invention integrates a cooling system into the vertical partition, which can cool the vertical partition as a whole and uniformly. This effectively eliminates the temperature difference between the vertical partition and the left and right side plates in traditional double-inlet double-outlet hot presses, ensuring that the temperature of each area of ​​the hot press plate is uniform during operation, thereby significantly improving the processing accuracy and stability of the product.

[0018] The embodiments of this utility model will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in this specification are not exhaustive and do not represent the only embodiments of this utility model. The following corresponding embodiments are only for clearly illustrating the utility model content of this patent and are not intended to limit its implementation. For those skilled in the art, different variations and modifications can be made based on the described embodiments. Any obvious variations or modifications that fall within the technical concept and utility model content of this utility model are also within the protection scope of this utility model.

[0019] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a double-inlet double-outlet hot press, including a frame 1100, two static hot press plates 1200 on the left and right, two active hot press plates 1300 on the left and right, a drive mechanism 1400, and a multi-layer dynamic hot press unit 1500.

[0020] like Figure 2As shown, the frame 1100 includes two side panels 1110 on the left and right sides, with an upper crossbeam 1120 and a lower crossbeam 1130 between the two side panels 1110. The upper crossbeam 1120 is located at the top, and a vertical partition 1140 is formed between the upper crossbeam 1120 and the lower crossbeam 1130 between the two side panels 1110.

[0021] Among them, frame 1100 is a welded frame, which makes it easier to control the processing accuracy compared to the traditional structure of multiple parts spliced ​​together by bolts.

[0022] like Figure 3 As shown, the opposite surfaces of the side plate 1110 and the vertical partition 1140 are both fixed with rails 1150 and support blocks 1160 by bolts. Taking the left side plate 1110 as an example, its right side is provided with two rails 1150 arranged at intervals. Correspondingly, the left side of the vertical partition 1140 is also provided with two rails 1150. These two rails 1150 are symmetrical to the two rails 1150 on the right side of the left side plate 1110. At the same time, as Figure 3 As shown, four support blocks 1160 are also provided on the right side of the left side panel 1110. The four support blocks 1160 are arranged symmetrically in pairs, with the two support blocks 1160 on the same side arranged vertically. Figure 4 As shown, multiple support surfaces 1161 are formed on each support block 1160, forming two rows of support surfaces. The multiple support surfaces 1161 on the same support block 1160 are distributed in a stepped manner. The multiple support surfaces 1161 in the same row (all support surfaces 1161 of the two support blocks 1160 arranged vertically on the same side) are arranged at equal intervals vertically, corresponding one-to-one with the multi-layer dynamic hot pressing unit. Of course, the multiple support surfaces 1161 in the same row can also be formed on the same support block 1160. Correspondingly, four support blocks 1160 are also provided on the left side of the vertical partition 1140. These four support blocks 1160 are symmetrical to the four support blocks 1160 on the right side of the left side plate 1110.

[0023] Among them, the area on the opposite surface of the side plate 1110 and the vertical partition 1140 where the track 1150 and the support block 1160 are set is the finishing area.

[0024] A cooling system is provided on the vertical partition 1140 to uniformly cool the entire vertical partition 1140. In this embodiment, the cooling system is a water-cooling system, such as... Figure 5 and Figure 6As shown, it includes a refrigerant inlet 1171 and a refrigerant outlet 1172 located at the top of a vertical partition 1140, and refrigerant pipes 1173 evenly distributed inside the vertical partition 1140. The refrigerant pipes 1173 include a first pipe section 1173a extending in an S-shape from top to bottom and a vertical second pipe section 1173b. The upper opening of the first pipe section 1173a is connected to the refrigerant inlet 1171, and the lower opening is connected to the lower opening of the second pipe section 1173b. The upper opening of the second pipe section 1173b is connected to the refrigerant outlet 1172. The first pipe section 1173a is composed of multiple longitudinally and transversely arranged pipes. A sealing element 1173c is provided at the corner of the longitudinally and transversely arranged pipes, so that the refrigerant can flow in an S-shape.

[0025] like Figure 2 As shown, the left and right static heat plates 1200 are fixed to the lower surface of the upper crossbeam 1120 by bolts, and are located on the left and right sides of the vertical partition 1140 respectively. The left and right active heat plates 1300 are located directly below the left and right static heat plates 1200, and are vertically opposite to the two static heat plates 1200.

[0026] Each active and static heat press plate has a heat medium inlet and a heat medium outlet, which are connected to the heat medium supply system. The active and static heat press plates have evenly distributed heat medium pipelines (S-shaped) inside, which are connected to the heat medium inlet and outlet. This structure is existing technology and will not be described in detail here.

[0027] like Figure 1 and Figure 2 As shown, the drive mechanism 1400 is used to drive the left and right active hot press plates 1300 to rise and fall. It includes two hydraulic cylinders 1410 on the left and right. The two hydraulic cylinders 1410 are fixed to the lower crossbeam 1130 and are both connected to the same oil supply system 2. The power output end of the two hydraulic cylinders 1410 is connected to the corresponding active hot press plate 1300 respectively.

[0028] like Figure 2 As shown, each layer of dynamic hot pressing unit 1500 includes two passive hot pressing plates 1510 on the left and right. The two passive hot pressing plates 1510 slide vertically and vertically with the vertical partition 1140 and the corresponding side plate 1110, and are located between the corresponding active hot pressing plate 1300 and static hot pressing plate 1200.

[0029] The left and right passive hot press plates 1510 have the same structure. Specifically, taking the left passive hot press plate 1510 as an example, as follows... Figure 7As shown, it has four sliding blocks 1511 located at the four corners. The four sliding blocks 1511 correspond one-to-one with the two tracks 1150 on the right side of the left side plate 1110 and the two tracks 1150 on the left side of the vertical partition 1140 and are slidably engaged. The contact surface between the sliding blocks 1511 and the tracks 1150 is an inclined surface that forms a certain angle (e.g., 45 degrees) with the edge of the passive heat-pressing plate 1510 in the horizontal cross-section, ensuring that the sliding guidance of the passive heat-pressing plate 1510 and the tracks 1150 remains effective under the condition of thermal expansion. At the same time, the left and right sides of the passive heat-pressing plate 1510 are respectively... It has two supported parts 1512. The two supported parts 1512 on the left are supported by two corresponding support surfaces 1161 on the right side of the left side plate 1110, and the two supported parts 1512 on the right are supported by two corresponding support surfaces 1161 on the left side of the vertical partition 1140. This allows multiple passive hot press plates 1510 to be evenly spaced in the frame 1100, which facilitates feeding the passive hot press plates 1510. In addition, since the multiple support surfaces 1161 are distributed in a stepped manner, the passive hot press plates 1510 will not interfere with the support blocks 1160 when sliding up and down.

[0030] like Figure 8 As shown, each passive hot press plate 1510 has a heat medium inlet 1513 and a heat medium outlet 1514. The heat medium inlet 1513 and the heat medium outlet 1514 are connected to the heat medium supply system 3. The passive hot press plate 1510 has evenly distributed heat medium pipelines (S-shaped) inside. The heat medium pipelines are connected to the heat medium inlet 1513 and the heat medium outlet 1514. The above structure is the prior art and will not be described in detail here.

[0031] In addition, such as Figure 7 As shown, the front edge of the passive hot press plate 1510 is provided with two guide wheels 1515 for guiding the loading plate onto the passive hot press plate. The upper surface of the passive hot press plate 1510 is provided with symmetrically arranged horizontal and vertically oriented strip grooves 1516. Each strip groove 1516 is provided with an elastic pressure strip 1517 to prevent the loading plate from directly contacting and wearing the upper surface of the passive hot press plate 1510 during loading. Figure 9 As shown, the elastic pressure strip 1517 includes a pressure strip body 1517a, multiple fixing bolts 1517b, and multiple elastic self-recovering components 1517c.

[0032] The pressure strip body 1517a is made of wear-resistant steel and is compatible with the strip groove 1516. The upper surface of the end is beveled to facilitate the guidance of the loading plate onto the pressure strip body 1517a.

[0033] The pressure strip body 1517a has multiple through holes 1517d evenly distributed along the front-back direction, and the through holes 1517d are stepped holes.

[0034] The number of fixing bolts 1517b is the same as the number of through holes 1517d, and they respectively pass through the corresponding through holes 1517d and are threaded to the bottom of the slot 1516. The upper end of the fixing bolt 1517b has a limiting cap 1517e, which abuts against the stepped surface of the stepped hole. See [reference needed]. Figure 10 .

[0035] The number of elastic self-recovering parts 1517c is the same as the number of fixing bolts 1517b. Multiple elastic self-recovering parts 1517c are provided between the pressure strip body 1517a and the bottom of the groove, and are respectively passed through by the fixing bolts 1517b.

[0036] Among them, the elastic self-recovering component 1517c uses a leaf spring, which can ensure that the contact surface with the bottom of the groove is horizontal after being compressed.

[0037] During loading, the loading carrier plate is guided onto the pressure strip body 1517a. Under the gravity of the carrier plate and the material to be processed on it, the elastic self-recovering component 1517c is compressed, and the pressure strip body 1517a is pressed down into the strip groove 1516 from its original position, so that the carrier plate contacts the upper surface of the passive hot press plate 1510. During unloading, under the action of the elastic self-recovering component 1517c, the pressure strip body 1517a is bounced upward and returns to its original position under the constraint of the limit cap 1517e, preventing the pressure strip body 1517a from being bounced away from the fixing bolt 1517b.

[0038] During operation, the left and right hot press plates are initially spaced vertically. The feeding mechanism first simultaneously feeds the materials to be processed, carried by the carrier plates on both sides, onto the left and right hot press plates (active and passive hot press plates). Then, the oil supply system 2 and the heat transfer medium supply system 3 are activated. When the hot press plates reach the set temperature, the drive mechanism 1400 pushes the active hot press plate 1300 to press multiple passive hot press plates 1510 onto the static hot press plate 1200, thereby applying pressure to each layer of materials to be processed and achieving hot pressing. During this process, the cooling system 1170 operates to uniformly cool the vertical partition 1140, ensuring that the temperature at the vertical partition 1140 is balanced with the temperature at the left and right side plates 1110, thus guaranteeing processing quality. After hot pressing is completed, the oil supply system 2 and the heat transfer medium supply system 3 are turned off, and the left and right hot press plates return to their initial positions. Finally, the unloading mechanism simultaneously removes the processed products from the left and right carrier plates.

[0039] As can be seen from the above, the double-inlet double-outlet hot press provided by this utility model integrates a cooling system on the vertical partition, which can cool the vertical partition as a whole and uniformly. This can effectively eliminate the temperature difference between the vertical partition and the left and right side plates in the traditional double-inlet double-outlet hot press, and ensure that the temperature of each area of ​​the hot press plate is uniform during operation, thereby significantly improving the processing accuracy and stability of the product.

[0040] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
