Description

Technical Field

[0001] This utility model relates to the field of load-bearing frames, specifically a load-bearing frame for pressure processing equipment. Background Technology

[0002] Die-casting machines, injection molding machines, and many pressure processing equipment all operate within a load-bearing frame. The existing structure consists of a head and tail plate plus four central Green columns. The head and tail plates have holes and load-bearing surfaces, while the Green columns have nuts. The nuts contact the load-bearing surfaces on the head and tail plates and bear the maximum pressure of the processing equipment. Since there are four sets of nuts that contact the corresponding load-bearing surfaces of the head and tail plates, the force on each contact surface needs to be uniform. This places high demands on the machining accuracy and assembly adjustment of the head and tail plates and Green column nuts. If the machining accuracy or assembly adjustment is not proper, it will cause uneven force distribution, resulting in deformation of the head and tail plates, and may even cause the Green columns to break. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a load-bearing frame for a pressure processing device, effectively overcoming the shortcomings of existing technologies.

[0004] This utility model is achieved through the following technical solution: a load-bearing frame for a pressure processing equipment, consisting of a head plate, a tail plate, and load-bearing tie rods. In application, the head plate and tail plate are subjected to outward pressure. The load-bearing tie rods and the head and tail plates have corresponding load-bearing surfaces. There is a deformation pad space between the load-bearing surfaces of the head and tail plates and the load-bearing surfaces of the tie rods. A metal load-bearing deformation pad is placed in the deformation pad space after being heated. A pressure applying mechanism applies pressure to squeeze the metal load-bearing deformation pads between the load-bearing surfaces of the head and tail plates and the load-bearing surfaces of the tie rods, causing the metal load-bearing deformation pads to deform. After deformation, the deformation pads automatically form a surface that adapts to the load-bearing surfaces of the head and tail plates and the load-bearing tie rods. After deformation, the head plate, tail plate, and load-bearing tie rods are fixed together with screws.

[0005] As a preferred technical solution, the heating temperature of the metal deformation pad is the hot forging temperature of the metal material, and the force applied by the pressure applying mechanism is greater than the deformation resistance calculated based on the deformed area of ​​the metal deformation pad and the compressive strength of the metal at the heating temperature.

[0006] As a preferred technical solution, the force-applying mechanism is a hydraulic cylinder located between the inner sides of the head plate and the tail plate. After hydraulic oil is injected into the cylinder, the head plate and the tail plate are pushed outward.

[0007] As a preferred technical solution, the force-applying mechanism pulls the head plate and tail plate outwards respectively on the outside of the load-bearing tie rod, using the load-bearing tie rod as a reference.

[0008] As a preferred technical solution, the force-applying mechanism is to set an inclined surface on the load-bearing tie rod and have a matching wedge. The wedge and the inclined surface of the load-bearing tie rod cooperate to pull the head plate and tail plate outward relative to the load-bearing tie rod.

[0009] As a preferred technical solution, the load-bearing surface is a plane, several arc surfaces, or a sawtooth shape.

[0010] As a preferred technical solution, the deformation pad is a flat plate, a cylinder, or a small square column.

[0011] The beneficial effects of this utility model are as follows: This utility model is used for the outer frame of pressure processing equipment such as die casting and injection molding machines. It consists of a head plate, a tail plate, and several load-bearing tie rods or frame-type load-bearing tie rods. During operation, the head plate and tail plate bear outward pressure respectively. There are corresponding load-bearing surfaces between the outer sides of the head plate and tail plate and the tie rods. There are deformation pads between the head plate, tail plate, and the load-bearing surfaces of the tie rods. The deformation pads are made of metal material. After heating, they are placed between the head plate, tail plate, and the load-bearing surfaces of the tie rods. Force is applied between the head plate, tail plate, and tie rods to deform the deformation pads. After deformation, the head plate, tail plate, and tie rods are fixed, which can reduce the processing accuracy requirements of the head plate, tail plate, and tie rods. Attached Figure Description

[0035] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0036] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0037] Example 1

[0038] like Figure 1 and Figure 2 The load-bearing tie rod 1 and the load-bearing tie rod head and tail plates 2 are shown. The load-bearing tie rod 1 is I-shaped and has a load-bearing surface 101. The load-bearing tie rod head and tail plates 2 have a head and tail plate load-bearing surface 201, a head and tail plate working surface 202, and a tie rod groove 203. Figure 3 As shown, the four load-bearing tie rods 1 and the two load-bearing tie rod head plates and end plates' load-bearing contact surfaces 3 are required to fit perfectly and distribute the force evenly. However, in the actual processing, there will be errors in the dimensions of each component. Therefore, the contact conditions between the load-bearing tie rods and the end plates' load-bearing contact surfaces 3 are inconsistent, resulting in uneven force distribution. This can cause deformation of the load-bearing tie rod head plates 2, and even breakage of the load-bearing tie rods 1. Similarly, Figure 6 The load-bearing contact surfaces 6 and 5 of the load-bearing frame and the head and tail plates in the figure must fit perfectly and be evenly stressed.

[0039] Solutions such as Figure 7 As shown, there is a load-bearing tie rod deformation pad 7 between the load-bearing surface 101 of the tie rod and the load-bearing surface 201 of the head and tail plates. Figure 7The load-bearing tie rod 1 and the load-bearing tie rod head and tail plates 2 have 16 load-bearing contact surfaces 3. Each load-bearing tie rod contact surface 101 and head and tail plate contact surface 201 has a load-bearing tie rod deformation pad 7. The material of the load-bearing tie rod deformation pad 7 can be a metal material, such as aluminum-copper alloy or steel. The assembly drawing is shown below. Figure 14 As shown, a shim-added load-bearing tie rod deformation pad 7 is placed between the load-bearing surface 101 of the tie rod and the load-bearing surface 201 of the head and tail plates. The load-bearing tie rod deformation pad 7 is heated before placement, with the heating temperature determined according to the hot forging heating specifications of the material. A hydraulic cylinder 9 is located between the working surfaces 202 of the two head and tail plates. Hydraulic oil is injected into the hydraulic cylinder 9, causing the hydraulic piston 901 to extend, as shown by the two arrows in the figure. This pushes the working surfaces 202 of the two head and tail plates outward, causing the load-bearing tie rod deformation pad 7 between the load-bearing surface 201 of the head and tail plates and the load-bearing surface 101 of the tie rod to be compressed and deformed. This allows the load-bearing tie rod deformation pad 7 to adapt to the shape of the load-bearing surface 101 of the tie rod and the load-bearing surface 201 of the head and tail plates. The deformation position at each location... The position is such that the load-bearing surface 101 of the tie rod and the load-bearing surface 201 of the head and tail plates are in close contact with the deformed load-bearing tie rod deformation pad 7. The pressure of the hydraulic cylinder 9 is confirmed according to the pressure required for the thermal deformation of the load-bearing tie rod deformation pad 7. After the load-bearing tie rod deformation pad 7 has completed its deformation, the load-bearing tie rod 1 and the load-bearing tie rod head and tail plates 2 are fixed to each other with screws, thus completing the assembly of the load-bearing frame. Because the load-bearing tie rod deformation pad 7 can undergo large deformation under heating, the load-bearing surfaces of the load-bearing tie rod and the head and tail plates are machined very roughly. The load-bearing tie rod can be used directly after gas cutting or laser cutting of steel plates. When the head and tail plates are made of castings, the cast surface can be used directly. When the head and tail plates are made of welded steel plates, the blanks can be used directly, which can significantly reduce production costs.

[0040] Example 2

[0041] Unlike Example 1, as Figure 13 As shown, the assembly of the load-bearing frame and the load-bearing frame head and tail plates also involves a hydraulic cylinder 9 between the working surfaces 502 of the two head and tail plates. The hydraulic piston 901 extends and presses the working surfaces 502 of the head and tail plates, causing the load-bearing surfaces 501 and 401 of the load-bearing frame to squeeze the load-bearing frame deformation pad 8, thus adapting the load-bearing frame deformation pad. The load-bearing surfaces 501 and 401 of the load-bearing frame head and tail plates deform. After deformation, the load-bearing frame 4 and the load-bearing frame head and tail plates 5 are fixed to each other with screws, thus completing the assembly of the load-bearing frame.

[0042] Example 3

[0043] Unlike the above embodiments, as follows Figure 15As shown, the head and tail plates 5 of the load-bearing frame have a central hole 503. Tension-bearing plates 10 are located at both ends of the frame. Each tension-bearing plate 10 has a hole corresponding to the central hole 503 of the head and tail plates, through which tension rods 11 pass. One end of the tension rod 11 is a flange that presses against the working surface 502 of the head and tail plates, while the other end is a nut 12. When the deformation pad 8 of the load-bearing frame is heated, it is placed on the load-bearing surface 401 of the load-bearing frame and the load-bearing surface 501 of the head and tail plates. After clearing the gap, rotate nut 12 to press the working surface 502 of the head and tail plates outward through the bearing surfaces 501 and 401 of the bearing frame head and tail plates, thus completing the deformation pad 8 of the bearing frame. This deformation adapts to the shape of the bearing surfaces 401 and 501 of the bearing frame head and tail plates. After the deformation is complete, use screws to fix the bearing frame 4 and the bearing frame head and tail plates 5 together. Remove the tension rod 11, nut 12, and tension bearing plate 10. The frame assembly is now complete.

[0044] Example 4

[0045] Unlike the above embodiments, as follows Figure 16 As shown, the load-bearing tie rod 1 is replaced by a wedge-loaded tie rod 13. The wedge-loaded tie rod 13 has the same wedge-loaded tensile load-bearing surface 1301 as the load-bearing surface 101 of the load-bearing tie rod. Each wedge-loaded tensile load-bearing surface 1301 also has a wedge surface 1302. The assembly drawing is as follows. Figure 17 and Figure 18 As shown, Figure 17 There is no oblique wedge 14 in the middle. Figure 18 The diagram shows a wedge 14, whose inclined surface 1401 mates with the wedge-loaded tensile bearing surface 1302, and whose flat surface 1402 mates with the working surface 202 of the head and tail plates. Figure 18 The pressure mechanism, indicated by the arrow, presses the wedge 14 in the direction of the arrow, causing the working surface 202 of the head and tail plates to be compressed. This causes the deformation pad 7 of the load-bearing tie rod to deform to adapt to the shape of the load-bearing surface 1301 with the wedge and the load-bearing surface 201 of the head and tail plates. After the deformation is completed, screws are used to fix the load-bearing tie rod 13 with the wedge and the load-bearing tie rod head and tail plates 2 to each other, thus completing the frame assembly.

[0046] Example 5

[0047] Unlike the above embodiments, as follows Figure 19 and Figure 20 As shown, the load-bearing surface of the tie rod or the head and tail plate can be serrated or several semi-circular arcs, and the load-bearing deformation pad can be a cylinder or a small square column. The figure shows the small square column deformation pad 701 and the cylindrical deformation pad 702. The load-bearing surface of the tie rod and the load-bearing surface of the head and tail plate can be used in a mixture of various shapes.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
