[0004] Although the patented design features a pressure block position adjustment function, in actual adjustment, the position of the pressure block needs to be changed by tightening the fixing bolts. This adjustment method is cumbersome and time-consuming when facing frequent position adjustment needs, greatly reducing the ease of use and operational efficiency of the equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing methods require tightening fixed bolts to change the position of the pressure block during actual adjustment. This adjustment method is cumbersome and time-consuming when facing frequent position adjustment needs, greatly reducing the ease of use and operational efficiency of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-functional four-column hydraulic stretching forming machine, comprising a hydraulic press body, an extrusion plate connected to the output end of the hydraulic press body, and movable adjustment components connected to both bottom surfaces of the extrusion plate, the movable adjustment components comprising two sets of fixed frames, a slide rod fixedly connected between the two sets of fixed frames, a pressure block connected to the surface of the two sets of slide rods, a slider connected to the front and rear end surfaces of the pressure block, a connecting block connected to both outer surfaces of the pressure block, two sets of springs connected inside the two sets of connecting blocks, a pull rod inserted inside the two sets of springs, a push plate connected to the top of the two sets of pull rods, an insert block connected to the top of the push plate, and a handle connected to the bottom of the two sets of pull rods. The extrusion plate has slots equidistantly spaced at the center of its bottom surface, and grooves are formed on the bottom surface of the extrusion plate near the front and rear ends of the slots. Furthermore, the pressure blocks are connected in a sliding manner, and the pressure blocks are connected in a sliding manner through a slider and a groove.

[0007] Furthermore, the push plate and the spring form a sliding connection, and the insert block and the slot form a mating connection.

[0008] Furthermore, the outer surface of the push plate is in contact with the inner wall of the connecting block.

[0009] Furthermore, both sides of the connecting block are connected to a disassembly and assembly component, which includes a side lug, and the upper and lower surfaces of the side lug are connected to a sleeve.

[0010] Furthermore, a hand-tightening bolt is inserted into the inside of the sleeve, and a limit block is fixedly connected to the surface of the hand-tightening bolt.

[0011] Furthermore, the pressure block has a threaded groove at the position where it matches the hand-tightening bolt.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when the position of the pressure block needs to be adjusted, the handle can be pulled down to retract the insert block. After sliding it to the appropriate position, the handle can be released, and the spring will automatically push the insert block to complete the quick fixation. This avoids the inconvenience of traditional bolt fixing methods when frequently adjusting the position, thus improving the ease of use and operational efficiency of the equipment. In this invention, when the spring experiences elastic fatigue after prolonged use, the hand-tightening bolt can be loosened, allowing the front end of the bolt to be removed from the threaded groove. The connecting block can then be directly replaced, ensuring the stability of the insert block when it is inserted into the slot for fixation. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1, as Figure 1 - Figure 4As shown, this utility model provides a multifunctional four-column hydraulic stretching forming machine, including a hydraulic press body 1. An extrusion plate 2 is connected to the output end of the hydraulic press body 1. Movable adjustment components 3 are connected to the bottom surfaces of both sides of the extrusion plate 2. Each movable adjustment component 3 includes two sets of fixed frames 301, with slide rods 302 fixedly connected between the two sets of fixed frames 301. Pressure blocks 303 are connected to the surfaces of the two sets of slide rods 302. Sliding blocks 304 are connected to the front and rear end surfaces of the pressure blocks 303. The outer sides of the pressure blocks 303 are... Each of the two sets of connecting blocks 305 is connected to a connecting block 305. Two sets of springs 306 are connected inside each of the two sets of springs 306. Pull rods 307 are inserted into the inside of each of the two sets of springs 306. Push plates 309 are connected to the top of each of the two sets of pull rods 307. Insert blocks 310 are connected to the top of each push plate 309. Handles 308 are connected to the bottom of each of the two sets of pull rods 307. Slots 312 are equidistantly spaced at the center of the bottom surface of the extrusion plate 2. Slide grooves 311 are formed on the bottom surface of the extrusion plate 2 near the front and rear ends of the slots 312. The pressing blocks 303 are slidably connected to each other. The pressing blocks 303 are slidably connected to the slide grooves 311 via sliders 304. Push plates 309 and springs 306 are slidably connected. Insert blocks 310 and slots 312 are inserted into each other. The outer surface of the push plate 309 is in contact with the inner wall of the connecting block 305.

[0018] The effect achieved in Embodiment 1 is that when hydraulic processing of a workpiece is required, the workpiece is placed on the base and positioned between two electric actuators. The workpiece is clamped by the relative movement of two clamping plates. When the position of the pressure block 303 needs to be adjusted, the two sets of handles 308 can be pulled down, so that the handles 308 can drive the push plate 309 through the pull rod 307 to squeeze the spring 306 and drive the insert block 310 to be pulled out from the slot 312 at the current position. Then, the pressure block 303 is pushed, so that the slider 304 is moved to adjust its position in the slide groove 311. When the position is adjusted to a suitable position, the handles 308 are released, so that the spring 306 can release its own elasticity to push the push plate 309 to drive the insert block 310 to be inserted into the slot 312 after the position is adjusted and fixed. This avoids the problem of the inconvenience of the traditional bolt fixing method when the position is frequently adjusted, and improves the ease of use and operating efficiency of the equipment.

[0019] Example 2, as Figure 1 and Figure 5 As shown, both sides of the connecting block 305 are connected to the disassembly and assembly components 4. The disassembly and assembly components 4 include side ears 401. Both the upper and lower surfaces of the side ears 401 are connected to sleeves 402. A hand-tightening bolt 403 is inserted into the sleeve 402. A limit block 404 is fixedly connected to the surface of the hand-tightening bolt 403. A threaded groove 405 is opened at the position where the pressure block 303 matches the hand-tightening bolt 403.

[0020] The effect achieved in Embodiment 2 is that when the spring 306 experiences elastic fatigue after prolonged use and the connecting block 305 needs to be disassembled and replaced, the hand-tightening bolt 403 can be reversed so that the front end of the hand-tightening bolt 403 can be removed from the threaded groove 405. At the same time, the limiting block 404 will slide within the sleeve 402. Then, the connecting block 305 can be directly removed, and the new connecting block 305 can be attached to the surface of the pressure block 303. Tighten the hand-tightening bolt 403 so that the hand-tightening bolt 403 can enter the threaded groove 405 of the pressure block 303 for threaded fixation. This ensures the stability of the insert 310 when it is inserted into the slot 312 for fixation.

[0021] Working principle: When the position of the pressure block 303 needs to be adjusted, the handle 308 can be pulled down to retract the insertion block 310. After sliding and adjusting to the appropriate position, the handle 308 can be released, and the insertion block 310 can be automatically pushed by the spring 306 to complete the quick fixation. This avoids the inconvenience of the traditional bolt fixing method when frequently adjusting the position, and improves the ease of use and operating efficiency of the equipment. When the spring 306 experiences elastic fatigue after long-term use, the hand-tightening bolt 403 can be loosened so that the front end of the hand-tightening bolt 403 can be removed from the threaded groove 405. Then, the connecting block 305 can be replaced directly, ensuring the stability of the insertion block 310 when it is inserted into the slot 312 for fixation.

[0022] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
