Description

Technical Field

[0001] This invention relates to the field of forging technology, and specifically to a precision forging machine tool for an integrated shackle body. Background Technology

[0002] The integrated leg shackle body is a restraint-type metal component manufactured using a one-piece forging process, without welding or splicing. Its core feature is the hinged connection of two shackle rings, one of which is flat at both ends with connecting holes, while the other shackle ring is integrally formed with the locking mechanism mounting base. It possesses high strength, resistance to damage, and wear resistance, and is mainly used in scenarios with stringent requirements for the safety and reliability of restraint equipment, such as judicial detention and security control. Currently, using appropriate forging forming machine tools, metal billets can be forged into shackle body blanks that meet dimensional accuracy and mechanical performance requirements under high temperature and high pressure environments. This effectively solves the problems of insufficient strength, easy breakage, and large precision deviations inherent in traditional split welding processes. It is suitable for large-scale, high-precision restraint equipment production scenarios to meet the stringent requirements of the judicial field for equipment safety performance and standardized manufacturing.

[0003] The utility model patent with publication number CN215998546U discloses a forging equipment for processing iron chains. The base has legs fixedly connected to both the left and right sides of its bottom, and the two legs are of the same size. The bottom of each leg is fixedly installed with a foot by screws. The equipment includes a connecting plate fixedly connected to the top of the base, and the width of the connecting plate is greater than the width of the base. A forging frame is fixedly connected to the top of the connecting plate, and an electric telescopic rod is fixedly installed inside the forging frame.

[0004] The forging equipment for iron chain processing in the aforementioned patent, when forging the billet, is similar to general forging forming machine tools. For bending and forging the billet, forging the flattened ends, and even for openings on the flattened ends, it is necessary to process the billet by transferring it between different processing machine tools, resulting in low processing efficiency. When the billet is bent and forged, and then the flattened ends are forged separately, if the edges of the flattened ends and the connection between the flattened ends and the main body are not properly limited due to the forging, uncontrollable deformation is likely to occur, affecting the processing quality. After the billet is forged and formed at different stages, for the billet that is tightly adhered to the mold cavity, it is necessary to manually pry it out with tools, which is inconvenient for collection. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of low processing efficiency and quality, and inconvenient collection in general shackle body forging machine tools. This invention provides a precision forging machine tool for one-piece shackle bodies.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: A precision forging machine for an integrated shackle body includes a forging box with a forging cavity and a collection cavity on the upper and lower sides respectively. Two symmetrical elastic side dies are slidably engaged at the bottom of the forging cavity. A semi-enclosed part is fixedly connected to the top of each of the two elastic side dies on opposite sides. A groove is opened at the bottom of the left elastic side die. A U-shaped elastic frame is slidably engaged in the right elastic side die. Drill rods are slidably inserted into the front and rear sides of the middle of the elastic frame. The drill rods on both sides can pass through the two elastic side dies and be inserted into the groove. Two auxiliary rods are fixedly connected to the left and right walls at the bottom of the forging cavity, which slide through and exit the corresponding elastic side dies. A hydraulic cylinder is fixedly connected to the middle of the upper wall of the forging cavity, and a top mold is fixedly connected to the bottom of the hydraulic cylinder. A mold closing assembly is provided on the top mold to drive the elastic side molds on both sides to move towards each other. A sliding frame is slidably engaged in the middle of the forging cavity. A forming column is fixedly connected to the front and rear walls of the inner cavity of the sliding frame. A precision forging assembly is provided on the outer wall of the forging cavity to first drive the sliding frame to move down and then drive the elastic frame to move to the left.

[0007] Furthermore, the bottom of the forging box is fixedly connected with four support legs. The lower wall of the collection chamber at the bottom of the forging box is designed to slope downward to the left. The upper wall of the collection chamber has an opening that communicates with the trough. The right wall of the opening is aligned with the left end of the right elastic side mold. A sieve plate is fixedly connected between the front and rear walls of the collection chamber. The sieve plate is fixedly overlapped on the lower right wall of the collection chamber. The sieve plate is composed of a vertical part on the left and an inclined part on the right. The vertical part is located between the two elastic side molds. The surface of the inclined part has sieve holes. A vibrator is installed on the lower wall of the inclined part of the sieve plate.

[0008] Furthermore, each of the auxiliary rods on the left and right sides has an arc surface at one end, the axis of the arc surface is parallel to the vertical plane, and the arc surface is aligned with the inner wall of the elastic side mold cavity.

[0009] Furthermore, the top mold has a U-shaped edge profile and a mold groove with a semi-circular cross-section. The front and rear edges of the top mold are provided with semi-circular grooves that are adapted to the size of the drill rod along the left and right directions.

[0010] Furthermore, the mold cavity after the elastic side molds and the top mold are closed is U-shaped with a circular cross-section. The forming pillar is located directly above the front and rear ports of the mold cavity, and the radius of the forming pillar is the same as the radius of the front and rear ports of the mold cavity.

[0011] Furthermore, the bottom of the forming column has a groove in the middle and through holes on the left and right sides. The size of the through holes is adapted to the size of the drill rod. The left end of the drill rod is rounded, and the bottom edge of the forming column is chamfered.

[0012] Furthermore, the mold clamping assembly includes a connecting plate in the shape of an inverted Ω that is slidably engaged with the inner wall of the forging cavity. The connecting plate is fixedly connected to the upper wall of the top mold. Wedge rods that are slidably inserted into the side wall of the forging cavity are fixedly connected around the bottom of the connecting plate. Guide grooves are provided on both the front and rear side walls of the elastic side mold. The guide grooves are formed by connecting and combining the upper wedge groove and the bottom vertical groove. The width of the vertical groove is the same as the width of the wedge rod. Both the wedge rod and the wedge groove have inclined surfaces that abut against each other. The lower wall of the forging cavity has a through groove corresponding to the wedge rod.

[0013] Furthermore, the precision forging assembly includes guide rails fixedly connected to the front and rear walls of the forging box. Telescopic cylinders are rotatably connected to the right sides of both the front and rear walls of the forging box. A pin located between the slide frame and the guide rail is rotatably connected to the telescopic end of the telescopic cylinder. Slide grooves are provided on both the front and rear walls of the slide frame. The pin is movably engaged with the slide groove and the guide rail, respectively.

[0014] Furthermore, the guide rail includes a short horizontal rail, an arc rail, and a long horizontal rail from left to right and from bottom to top. A U-shaped bracket is fixedly connected to the upper left side of the elastic frame, located inside the guide rail. The port of the bracket is located at the intersection of the short horizontal rail and the arc rail. The elastic frame is slidably engaged with the outer wall of the forging box.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, when the hydraulic cylinder drives the top mold to initially move downward, the mold closing assembly first drives the elastic side molds on both sides to move towards each other to close the mold. After the mold is closed, the rod-shaped blank is placed in the two semi-enclosed spaces. The hydraulic cylinder is then controlled to drive the top mold to move further downward, thereby bending and forging the blank. Then, the precision forging assembly is controlled to first drive the sliding frame to move the forming column downward to both sides of the mold cavity, thereby restricting and squeezing the bent blank from both ends and forging both ends of the blank to form a flat connecting part. After the forming column moves to the position, the precision forging assembly drives the elastic frame to move the drill rod to the left, thereby passing through the connecting part of the forming column and the blank, and ejecting the excess blank part into the trough for discharge. Thus, the hot forging forming of the blank through multiple processes is completed on the same machine tool, eliminating the need for the blank to be transferred between different processing machines, greatly improving processing efficiency and quality.

[0016] 2. This invention controls the two elastic side dies to separate after the billet is forged. The auxiliary rods on the front and rear sides can automatically push the formed material outward relative to the die cavity, avoiding adhesion to the die cavity. The ejected formed material slides down between the auxiliary rods under the action of gravity and automatically falls into the collection cavity. Compared with the traditional billet bending forging or forging flat connection parts, there is no need for manual tools to pry the billet out of the die groove, making collection more convenient and further improving processing efficiency.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] Example 1, as Figures 1-7 As shown, a precision forging machine tool for an integrated shackle body includes a forging box 1 with a forging cavity and a collection cavity on the upper and lower sides respectively. Two symmetrical elastic side molds 2 are slidably engaged at the bottom of the forging cavity. A semi-enclosed 21 is fixedly connected to the top of each of the two elastic side molds 2 on opposite sides. A slot is opened at the bottom of the left elastic side mold 2. A U-shaped elastic frame 22 is slidably engaged in the right elastic side mold 2. Drill rods 24 are slidably inserted into the front and rear sides of the middle of the elastic frame 22. The drill rods 24 on both sides can pass through the two elastic side molds 2 and be inserted into the slot. Two auxiliary rods 13 are fixedly connected to the left and right walls at the bottom of the forging cavity, which slide through and out of the corresponding elastic side molds 2. A hydraulic cylinder 31 is fixedly connected to the middle of the upper wall of the forging cavity. A top mold 32 is fixedly connected to the bottom of the hydraulic cylinder 31. A mold closing assembly is provided on the top mold 32 to drive the elastic side molds 2 on both sides to move towards each other. A sliding frame 4 is slidably engaged in the middle of the forging cavity. A forming column 41 is fixedly connected to the front and rear walls of the inner cavity of the sliding frame 4. A precision forging assembly is provided on the outer wall of the forging cavity to first drive the sliding frame 4 to move down and then drive the elastic frame 22 to move to the left.

[0021] The top mold 32 has a U-shaped edge profile and a mold groove with a semi-circular cross section. The front and rear edges of the top mold 32 are provided with semi-circular grooves that are adapted to the size of the drill rod 24 along the left and right directions.

[0022] The mold cavity after the elastic side molds 2 and the top mold 32 are closed is U-shaped and has a circular cross section. The forming pillar 41 is located directly above the front and rear ports of the mold cavity. The radius of the forming pillar 41 is the same as the radius of the front and rear ports of the mold cavity. The bottom center of the forming pillar 41 has a groove and through holes on the left and right sides.

[0023] Initially, the elastic side molds 2 on both sides are in the mold-separation state. The hydraulic cylinder 31 extends, causing the top mold 32 to move downward. In the initial downward movement, the top mold 32 drives the mold-closing assembly to move the elastic side molds 2 on both sides towards each other and close the mold. After mold closing, a release agent is sprayed into the mold cavity as needed. Each auxiliary rod 13 is passively dislodged from the mold cavity, and the two semi-enclosed parts 21 form a complete enclosure. The top mold 32 descends and approaches the top of the complete enclosure, but still leaves space for the blank. Subsequently, a heated, calibrated rod-shaped blank is placed between the two semi-enclosed parts 21 for positioning. The hydraulic cylinder 31 is then controlled to... The pressure cylinder 31 extends again, causing the top die 32 to move downwards. The elastic side dies 2 on both sides remain in a continuously closed state. The downward movement of the top die 32 uses the semi-circular die groove to squeeze the blank, causing the blank to bend. Under the constraint of the die cavity formed by the cooperation of the elastic side dies 2 on both sides, the blank bends into a U-shape. After the top die 32 moves to the bottom, the extension length of the hydraulic cylinder 31 is controlled. The precision forging assembly first drives the sliding frame 4 to move the forming column 41 downwards, extending it to both ends of the die cavity. When the forming column 41 moves downwards and squeezes, the blank inside the die cavity automatically deforms and fills the gaps. Under the constraint of the mold cavity, both ends are squeezed to form a flat connecting part in the middle. After the forming column 41 moves down into place, the control forging assembly moves further, the sliding frame 4 drives the forming column 41 to remain stationary, and the forging assembly drives the elastic frame 22 to move the drill rod 24 to the left, thereby passing through the connecting part of the forming column 41 and the blank to realize drilling, and ejecting the excess blank into the sluice to be discharged. In this way, the hot forging forming of the blank through multiple processes is completed on the same machine tool, eliminating the need for the blank to be transferred between different processing machines, which greatly improves processing efficiency and ensures processing quality. After the billet is forged, the precision forging assembly is reset first, and then the hydraulic cylinder 31 is reset. The two elastic side dies 2 automatically separate under their own elastic force. The auxiliary rods 13 on the front and rear sides can automatically push the forming material outward relative to the mold cavity to avoid sticking to the mold cavity. The ejected forming material slides down between the auxiliary rods 13 under the action of gravity and automatically falls into the collection cavity. Compared with the traditional bending forging or forging flat connection parts, there is no need for manual tools to pry the billet out of the mold groove, making collection more convenient and further improving processing efficiency.

[0024] In Example 2, based on the above examples, four legs are fixedly connected to the bottom of the forging box 1. The lower wall of the collection chamber at the bottom of the forging box 1 is designed to slope downward to the left. An opening is provided on the upper wall of the collection chamber to communicate with the trough. The right wall of the opening is aligned with the left end of the right elastic side mold 2. A sieve plate 11 is fixedly connected between the front and rear walls of the collection chamber. The sieve plate 11 is fixedly attached to the lower right wall of the collection chamber. The sieve plate 11 is composed of a vertical part on the left and an inclined part on the right. The vertical part is located between the two elastic side molds 2. The surface of the inclined part has sieve holes. A vibrator 12 is installed on the lower wall of the inclined part of the sieve plate 11.

[0025] When the precision forging assembly drills holes in the flat connecting part of the billet and pushes out the excess part into the trough for discharge, the waste material automatically falls through the opening onto the inclined lower wall of the collection chamber and is discharged to the left. When the billet is forged and the die is separated and the machine tool is reset, the vibrator 12 runs automatically. After the formed material falls through the opening and is blocked by the vertical part of the screen plate 11, it falls onto the inclined part of the screen plate 11. Affected by the vibration of the vibrator 12, the oxide scale on the surface of the formed material is automatically screened off onto the inclined lower wall of the collection chamber and discharged to the left, while the formed material is output to the right, thus facilitating collection and classification.

[0026] In Example 3, based on the above examples, the opposite ends of the auxiliary rods 13 on both the left and right sides are provided with arc surfaces, the axis corresponding to the arc surfaces is parallel to the vertical plane, and the arc surfaces are aligned with the inner wall of the elastic side mold 2 cavity.

[0027] By modifying the design, the auxiliary rod 13 passively ejects the molding material from the mold cavity during mold parting. The auxiliary rod 13 will not lift the molding material or hinder the material discharge. Furthermore, it will not interfere with the molding of the blank in the mold cavity during mold closing, making it safe and reliable to use.

[0028] In Example 4, based on the above examples, the through-hole sizes on the left and right sides of the bottom end of the forming column 41 are adapted to the size of the drill rod 24, the left end of the drill rod 24 is rounded, and the bottom edge of the forming column 41 is chamfered.

[0029] This design ensures that when the forming column 41 moves downward, it can reliably insert into both ends of the matching mold cavity, and when the drill rod 24 moves to the left, it can squeeze and drill through the blank and fit through the forming column 41, thus improving the drilling quality of the flat parts at both ends of the blank.

[0030] In Example 5, based on the above examples, the mold assembly includes a connecting plate 3 in the shape of an inverted Ω that is slidably engaged with the inner wall of the forging cavity. The connecting plate 3 is fixedly connected to the upper wall of the top mold 32. Wedge rods 33 that are slidably inserted into the side wall of the forging cavity are fixedly connected around the bottom of the connecting plate 3. Guide grooves 25 are provided on both the front and rear side walls of the elastic side mold 2. The guide grooves 25 are formed by connecting and combining the upper wedge groove and the bottom vertical groove. The width of the vertical groove is the same as the width of the wedge rod 33. Both the wedge rod 33 and the wedge groove have inclined surfaces that abut against each other. The lower wall of the forging cavity has a through groove corresponding to the wedge rod 33.

[0031] By using the inverted Ω-shaped design of the connecting plate 3, it is ensured that when the hydraulic cylinder 31 drives the top mold 32 and the connecting plate 3 to move down to the maximum distance, it will not be obstructed by the sliding frame 4. The operation of the mold closing assembly and the precision forging assembly will not interfere with each other. Initially, when the hydraulic cylinder 31 extends and drives the connecting plate 3 to move each wedge 33 down, the wedge 33 first squeezes the inclined surface of the wedge groove in the guide groove 25, thereby driving the elastic side molds 2 on both sides to overcome the elastic resistance and move towards each other to close the mold. After the mold is closed, as the hydraulic cylinder 31 continues to extend, the wedge 33 continues to move down and just inserts into the vertical groove, thereby stabilizing and limiting the unexpected separation of the elastic side molds 2 on both sides when the top mold 32 forges and shapes the billet.

[0032] In Example 6, based on the above examples, the precision forging assembly includes a guide rail 5 fixedly connected to the front and rear walls of the forging box 1. A telescopic cylinder 51 is rotatably connected to the right side of both the front and rear walls of the forging box 1. The telescopic end of the telescopic cylinder 51 is rotatably connected to a pin 52 located between the slide frame 4 and the guide rail 5. Slide grooves 42 are provided on both the front and rear walls of the slide frame 4. The pin 52 is movably engaged with the slide groove 42 and the guide rail 5, respectively.

[0033] The guide rail 5 includes a short horizontal rail, an arc rail, and a long horizontal rail from left to right and from bottom to top. The upper left side of the elastic frame 22 is fixedly connected to a U-shaped card seat 23 located inside the guide rail 5. The port of the card seat 23 is located at the intersection of the short horizontal rail and the arc rail. The elastic frame 22 is slidably engaged with the outer wall of the forging box 1.

[0034] When the telescopic cylinder 51 extends, the pin 52 is driven to move to the lower left along the arc rail. The pin 52 simultaneously presses the slide frame 4, causing the forming column 41 to move downward, thereby achieving the overall forging of the bent blank and the forming of the flat parts at both ends. After the slide frame 4 moves to the lower position, the pin 52 moves to the bottom of the arc rail and into the short horizontal rail, and is just locked in the card seat 23. As the telescopic cylinder 51 continues to extend, the pin 52 moves to the left along the short horizontal rail. The slide frame 4 causes the forming column 41 to remain stationary, while the card seat 23 drives the elastic frame 22 to make the drill rod 24 drill the flat part of the blank. During the subsequent reset, the elasticity of the elastic frame 22 is only used to maintain the initial position. The pin 52 can drive the card seat 23 to reset synchronously, avoiding the large bonding force of the drill rod 24 drilling into the blank and the insufficient reset power of the elastic frame 22.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
