DETAILED DESCRIPTION

[0039] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] The plate frame-supported press of the embodiment of the present invention comprises: an articulated seat 2, a bearing frame 1, a positioning seat 4, a workbench 6 and a jack 5. The bearing frame 1 is provided with a jack receiving groove 21 for assembling the jack 5 and a workpiece receiving groove 24 for assembling the workbench 6. The workbench 6 is inserted into the lower part of the bearing frame 1, and the bottom surface of the flat plate 27 in the workbench 6 is abutted against the top surface of the bottom beam 25. The jack 5 is arranged in the jack receiving groove 21, and the base end of the jack 5 is connected to the articulated seat 2 through a pin shaft 8 for pressing the workpiece. The articulated seat 2 is arranged in the jack receiving groove 21, and the articulated seat 2 is fixed to the top of the bearing frame 1 for fixedly connecting the jack 5. The positioning seat 4 is arranged at the lower part of the jack receiving groove 21, and the positioning seat 4 is provided with a second bolt 9 fixedly connected to the bearing plate 13 for fixing the jack 5 at a specified position.

[0041] Specifically, Figures 1 to 12 As shown, the extension direction of the carrier 1 is the up-down direction, the width direction of the carrier 1 is the left-right direction, and a jack receiving groove 21 and a workpiece receiving groove 24 are provided on the bearing plate 13 of the carrier 1 for assembling the jack 5 and the workbench 6. The workbench 6 is plugged into the lower part of the carrier 1, and the bottom surface of the flat plate 27 in the workbench 6 is in contact with the top surface of the bottom beam 25, for placing the workpiece and bearing the pressure of the jack 5.

[0042] The articulated seat 2 is arranged in the jack accommodating groove 21 and is in contact with the bottom surface of the top beam 19. The articulated seat 2 fixes the jack 5 through the pin 8. The jack 5 is arranged in the jack accommodating groove 21, and the base end of the jack 5 is connected to the articulated seat 2 through the pin 8 for pressing the workpiece. The positioning seat 4 is arranged at the lower part of the jack accommodating groove 21 and is fixedly connected to the bearing plate 13 through the second bolt 9 for fixing the jack 5 at a specified position.

[0043] Furthermore, the support frame 1 can be manufactured as an integral part to improve the structural strength of the support frame 1.

[0044] The plate frame-supported press of the embodiment of the present invention is provided with a carrier frame 1, on which a jack receiving groove 21 and a workpiece receiving groove 24 are provided for assembling a jack 5 and a workbench 6. The hinged seat 2 is provided in the jack receiving groove 21 and abuts against the bottom surface of the top beam 19 for fixedly connecting the jack 5. The jack 5 is provided in the jack receiving groove 21, and the base end of the jack 5 is connected to the hinged seat 2 through a pin shaft 8 for pressing the workpiece. Thus, no column is required, thereby reducing the manufacturing cost of the press.

[0045] At the same time, a large amount of steel is used during the manufacturing of the press, and the transportation and installation of the press is relatively difficult. The reason for these shortcomings and problems is that in order to bear the strong pressure of the jack, the upper bearing frame and the workbench are generally welded or cast into a box-type structure, and multiple ribs are set at their weak parts to enhance the rigidity of the upper bearing frame and the workbench. In this way, the strong pressure of the jack can be carried, which correspondingly increases the amount of steel used, and the transportation and installation of the press is relatively difficult.

[0046] In the press supported by the plate frame of the embodiment of the present invention, the workbench 6 is inserted into the support frame 1 and abuts against the support frame 1, the jack 5 is assembled in the jack accommodating groove 21 and abuts against the top beam through the hinge seat, and the force is applied to the support frame through the workbench 6. In this way, structural parts such as columns, clamps, and clamps involved in the conventional press are eliminated, and the number of structural parts is correspondingly reduced, thereby reducing the manufacturing cost of the press.

[0047] In some embodiments, the support frame 1 includes a support plate 13, a vertical plate 14, a top plate 12 and a positioning frame 15.

[0048] Specifically, Figures 1 to 12 As shown, the bearing frame 1 is composed of a bearing plate 13, a vertical plate 14, a top plate 12, and a positioning frame 15, wherein the bearing plate 13 is the main bearing member. The bearing plate 13 is formed by cutting and processing a jack accommodating groove 21 and a workpiece accommodating groove 24 on a whole steel plate, forming a top beam 19, two vertical beams 23 and a bottom beam 25, forming a bearing frame for bearing the pushing force of the jack 5. There is no weld in this bearing frame, and the tensile strength of the vertical beam 23 in the bearing plate 13 is used to bear the pushing force of the jack 5, thereby improving the bearing capacity.

[0049] Furthermore, the bearing plate 13 is made of Q690 steel to improve the structural strength of the bearing plate, so as to avoid reducing the overall structural strength of the press in the absence of columns.

[0050] The press machine supported by the plate frame in the embodiment of the present invention mainly involves cutting of the plate ruler and a small amount of milling and turning during the manufacturing of the support plate 13 used in the present invention. The number of cutting and processing equipment involved is small, the process involved is simple, a large amount of welding work is reduced, the working hours are relatively short, and the steel consumed is relatively small, which can reduce the manufacturing cost of the machine accordingly.

[0053] At the same time, the bearing plate 13 is the main bearing member. The bearing plate 13 is cut and processed on a whole steel plate to form a jack accommodating groove 21 and a workpiece accommodating groove 24, forming a top beam 19, two vertical beams 23 and a bottom beam 25, forming a bearing frame that bears the pushing force of the jack 5.

[0054] The top beam 19 , the vertical beam 23 and the bottom beam 25 are integrally formed to improve the structural strength of the bearing frame that bears the pushing force of the jack 5 , and to improve the bearing capacity of the bearing frame that bears the pushing force of the jack 5 .

Furthermore, the connection between the vertical beam 23 and the top beam 23 can be chamfered to avoid stress concentration at the connection between the vertical beam 23 and the top beam 19.

[0058] One end of the second reinforcing rib plate 44 is connected to the top end of another top beam 19, and the other end of the second reinforcing rib plate 44 is connected to the top beam. The second reinforcing rib plate 44 is arranged between the vertical beam 23 and the top beam 19 to strengthen the structural strength of the connection between the vertical beam 23 and the top beam 19. Furthermore, the connection between the vertical beam 23 and the top beam 23 can be chamfered to avoid stress concentration at the connection between the vertical beam 23 and the top beam 19. The first reinforcing rib plate 43 and the second reinforcing rib plate 44 are respectively arranged on different vertical beams 23 on the left and right, that is, the first reinforcing rib plate 43 and the second reinforcing rib plate 44 are arranged at intervals in the left and right directions. By arranging the first reinforcing rib plate 43 and the second reinforcing rib plate 44, the connection strength between the vertical beam 23 and the top beam 19 can be improved to avoid stress concentration at the connection between the vertical beam 23 and the top beam 19.
