[0042] Please refer to Figure 1-13 ,

[0043] like Figure 1 , 2As shown in Figure 3, the utility model provides a frame-type press machine, including an integrally cast frame 1 and a press machine 2, the press machine 2 including an output rod 21, the frame 1 including at least one operating port 10, the frame 1 integrally formed with a plate 11 and a plate 2 12, the plate 1 11 and the plate 2 12 being arranged opposite to each other, the plate 1 11 including a press station 111, the plate 2 12 including a press installation position 121, the press machine 2 installed to the press installation position 121 can move the output rod 21 toward the press station 111, the press station 111 protrudes from the surface of the plate 11 toward the press machine 2, the width of the operating port 10 is a, the width of the press station 111 is b, and a>b, in the process of machining the flatness or roughness of the press station 111, the tool head 7 of the machine tool can enter the frame 1 at one time to complete the machining. The use of an integrated casting frame 1 can effectively reduce the errors caused by the accumulation of different components. Although the method of assembling by stacking different components will cause the installation reference surface to shift after the installation reference surface is defined due to the increase in the number of installed components, and the large number of components will delay the organization time, and the warehouse material control is also more troublesome. The integrated casting can reduce the processing errors between components and the matching problems during splicing, thereby improving the accuracy and stability of the product. At the same time, this technology can also reduce the failure rate of the product during use and improve the overall quality of the product. The frame 1 is usually also processed by welding, but during the welding process, due to the effects of heat and stress, the welded parts are prone to deformation, which will cause the size of the welded parts to deviate from the design requirements. This deformation not only affects the geometric accuracy of the welded parts, but may also affect its assembly and coordination with other components, resulting in a decrease in the accuracy of the entire assembly. When the press-fitting station 111 protrudes from the surface of plate 11 and the width a of the operating port 10 is greater than the width b of the press-fitting station 111, it is convenient for the machine tool cutter head 7 to process a fine-machined surface. When the cutter head 7 enters from the operating port 10, the processing can be completed at one time, avoiding the steps of flipping the frame 1 or turning the cutter head 7, thereby reducing the number of repeated positioning times of the machine tool cutter head 7, thereby improving the processing accuracy. In this way, when the cutter head 7 processes the press installation position 121, the processing surface of the press-fitting station 111 can be directly used as the reference plane, reducing the cumulative error and improving the parallelism between the processing surface of the press-fitting station 111 and the processing surface of the press installation position 121, so that after the output rod 21 of the press 2 is pressed down, the processed workpiece is subjected to a more balanced force, thereby achieving a high-precision pressing effect. At the same time, fewer machine operation steps can reduce the programming language of the machine operator and reduce the workload of the machine operator. When the width a of the operation port 10 is greater than the width b of the press-fitting station 111, it is also beneficial to the retraction of the cutter head 7 after the processing is completed, and at the same time, the risk of the cutter head 7 colliding with the frame 1 is reduced. In this embodiment, the movement mode of the cutter head is as follows: Fig.13 As shown, the dotted line is the schematic direction of the feed route of the tool head 7, and the dotted line is the schematic direction of the cutting and retracting of the tool head 7 on the press-fitting station 111.

[0044] like Figure 3 , 4 As shown, the plate 11 has a groove 112 on one side away from the press installation position 121, the groove 112 includes a groove wall 1121, a protrusion 1122 is provided in the area of ​​the groove 112 corresponding to the output rod 21, and a connecting portion 1123 is provided between the protrusion 1122 and the groove wall 1121. In order to reduce the weight of the frame press and reduce the burden on the foot cup and casters, a groove 112 is provided on the side of the plate 11 away from the press installation position 121. The press 2 in this embodiment can be an existing technology such as an electric cylinder and a hydraulic cylinder. The working principle of the press 2 is no longer repeated here. When the press 2 is pressed down, it can generate a huge downward pressure Fa to support the press installation station 111. At this time, there is a groove 112 in the plate 11, and the press installation station 111 is easy to deform, causing the frame 1 to break and break. Based on this, the technical solution has a protrusion 1122 in the area of ​​the groove 112 corresponding to the output rod 21, and a connecting part 1123 is provided between the protrusion 1122 and the groove wall 1121. This strengthens the structure of the press installation station 111 and at the same time reduces gravity, thereby solving the above technical problems.

[0045] like Figure 5 As shown, the height of the protrusion 1122 is c, the height of the groove 112 is d, and c>d. The connecting portion 1123 can form a triangular block 1124. As a preferred solution, the height c of the protrusion 1122 is higher than the height d of the groove 112. When the connecting portion 1123 connects the protrusion 1122 and the groove 112, a triangular block 1124 can be formed. The triangle has stability, so the connecting portion 1123 can stably connect the protrusion 1122 and the groove wall 1121, and better resist the downward pressure Fa from the press 2.

[0046] like Figure 6 As shown, the connection part 1123 is distributed in a circular array around the protrusion 1122. The connection part 1123 distributed in a circular array can make the downward force of the output rod 21 more evenly dispersed.

[0047] like Figure 8 , 9As shown, the plate 12 has a groove 122 on one side away from the press-fitting station 111, and the groove 122 includes a groove wall 1221. A protrusion 1222 is provided in the middle of the groove 122, and a press mounting position 121 can be formed by the protrusion 1222. The press 2 can be installed on the press mounting position 121, and a connecting portion 1223 is provided between the protrusion 1222 and the groove wall 1221. In order to reduce the weight of the frame-type press and reduce the burden on the foot cup and casters, a groove 122 is provided on the side of the plate 12 away from the pressing station 111. The press 2 in this embodiment can be an existing technology such as an electric cylinder and a hydraulic cylinder. The working principle of the press 2 will not be repeated here. When the output rod 21 of the press 2 is against the pressing station 111, the press installation position 121 will be subjected to a huge reaction force Fb. At this time, there is a groove 122 in the plate 12, and the press installation position 121 is easy to deform, causing the frame 1 to break and break. Based on this, the technical solution has a protrusion 1222 in the middle area of ​​the groove 122, and a connecting part 1223 is provided between the protrusion 1222 and the groove wall 1221. This strengthens the structure of the press installation position 121 and at the same time has the effect of reducing gravity, thereby solving the above-mentioned technical problems.

[0048] like Figure 7 As shown, the height of the second protrusion 1222 is e, and the height of the second groove 122 is f, and e>f, and the second connecting portion 1223 can form a triangular block 1224. As a preferred solution, the height e of the second protrusion 1222 is higher than the height f of the second groove 122, and the second connecting portion 1223 can form a triangular block 1224 when connecting the second protrusion 1222 and the second groove 122. The triangle has stability, so the second connecting portion 1223 can stably connect the second protrusion 1222 and the second groove wall 1221, and better resist the reaction force Fb from the press 2.

[0049] like Figure 8 As shown, the second connection parts 1223 are distributed in a ring array around the second protrusion 1222. The second connection parts 1223 distributed in a ring array can make the reaction force of the output rod 21 more evenly dispersed.

[0050] like Fig. 9 As shown, the side of the second plate 12 close to the press-fitting station 111 has a beam 123, and the beam 123 is closed and arranged in contact with the edge of the second plate 12. The design of the beam 123 allows the second plate 12 to better resist the reaction force Fb and reduce the deformation of the second plate 12 away from the press-fitting station 111.

[0051] like Fig. 9As shown, in the frame 1, the connecting beam 123 and the plate 11 are connected by a connecting column 3, and both ends of the connecting column 3 are provided with reinforcing blocks 31, and the reinforcing blocks 31 are not in contact with the press-fitting station 111. The connecting column 3 not only serves to connect the press-fitting station 111 with the press installation position 121, but also receives the tensile force generated during the downward pressing of the output rod 21 of the press 2. When the connecting column 3 is subjected to the tensile force, according to the finite element analysis, it can be obtained as follows Fig.10 As shown in the results, in the frame 1 of the present technical solution, the edges at both ends of the connecting column 3 will deform outwards. According to the deformation characteristics of the connecting column 3 of the present technical solution, during the casting process of the frame 1, a casting space for the reinforcing block 31 is reserved at both ends of the connecting column 3, and the reinforcing block 31 cannot contact the pressing station 111 to prevent the pressing station 111 from deforming along with the reinforcing block 31 when the connecting column 31 is subjected to huge tensile force.

[0052] like Fig.12 As shown, the side of the plate 11 away from the press-fitting station 111 has a base 5 integrally formed with the frame 1 and with a connecting column 2 4, and the side of the connecting portion 1123 close to the base 5 has a connecting column 3 6 connected to the base 5, and the connecting column 3 6 is in the area below the press-fitting station 111. This frame press-fitting machine can integrally form a base 5 on the side of the plate 11 away from the press-fitting station 111 according to demand, and the base 5 is connected to the plate 111 through the connecting column 2 4. At the same time, there is a connecting column 3 6 connected to the base 5 in the area below the press-fitting station 111, and the connecting column 2 4 and the connecting column 3 6 can make the structure of the frame press-fitting machine stable. When there is no base 5 and connecting column 3 6, the frame press-fitting machine is shorter and can be placed on a workbench for operation. When the frame press-fitting machine has a base 5 and connecting column 3 6, the height of the frame press-fitting machine is increased so that it can be placed on the work floor for operation.
