Description

Technical Field

[0001] This utility model relates to the field of forging production technology, specifically to a punch press anti-deviation guide device for forging production. Background Technology

[0002] Forging is a metal processing technology that uses external force (pressure or impact) to plastically deform metal billets in a solid state, ultimately obtaining workpieces with specific shapes, sizes and excellent mechanical properties. The core principle is to utilize the plastic flow characteristics of metals to reshape the internal structure of the metal under pressure, thereby improving the key properties of the workpiece such as strength and toughness. It is an important process in the field of mechanical manufacturing for producing high-strength and high-reliability metal parts. A punch press for forging production is a special pressure forming equipment for realizing the plastic deformation of metal billets in the forging process. Its core is to transmit pressure to the mold or billet through the reciprocating motion of a slide driven by mechanical or hydraulic means, so that the metal is shaped into a preset shape in the solid state. It is a key piece of equipment connecting the forging blanking and forming process. Traditional punch press guide devices often employ an integrated, enclosed design to ensure the rigidity and sealing of the guide structure, without reserving a dedicated maintenance channel. This design results in the core guide components being completely enclosed within the enclosed structure. When components experience wear and tear due to long-term use, operators cannot directly access the maintenance area and must temporarily disassemble part of the guide structure to carry out maintenance work. The disassembly process not only consumes a lot of time but also requires specialized tools. Furthermore, frequent disassembly can easily cause secondary damage such as structural deformation, further increasing equipment maintenance costs. At the same time, the complex maintenance process prolongs equipment downtime, leading to production interruptions and directly reducing overall production efficiency, thus making it difficult to meet the demand for efficient and continuous production. Therefore, to address the above problems, a punch press anti-deviation guide device for forging production is proposed. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A forging production punch press anti-deviation guide device includes a bed 1, a stamping assembly 2, and a worktable 3. Support plates 4 are symmetrically and fixedly connected to both sides of the worktable 3. A guide bracket 5 is fixedly connected to the top of the support plate 4, and the top of the guide bracket 5 is fixedly connected to the bed 1. A guide assembly 6 is provided between the guide bracket 5 and the stamping assembly 2. A maintenance assembly 7 is provided on the outer side of the guide bracket 5. The maintenance assembly 7 includes a maintenance door 71 hinged to the middle of the outer side of the guide bracket 5. The outer side of the maintenance door 71 is flush with the outer side of the guide bracket 5. A pair of limiting frames 72 are symmetrically fitted longitudinally at both ends of the outer side of the maintenance door 71, and the limiting frames 72 are slidably arranged longitudinally on the outer side of the guide bracket 5. Positioning pins 73 are symmetrically inserted at the front and rear ends of the limiting frames 72. Two sets of positioning holes 74 are symmetrically opened longitudinally on both the front and rear sides of the guide bracket 5. A reset structure 75 is provided on the outer side of the limiting frames 72.

[0017] It should be noted that: the bed 1 provides a stable installation base for components such as the stamping assembly 2 and the worktable 3, ensuring the overall operational stability of the punch press; the support plate 4 is symmetrically fixed on both sides of the worktable 3, providing reliable support for the guide bracket 5; the top of the guide bracket 5 is fixed to the bed 1, further strengthening the rigidity of the guide structure; the core function of the guide assembly 6 is to limit the movement trajectory of the stamping assembly 2, preventing deviation during the stamping process; and the maintenance assembly 7 provides a convenient passage for the inspection and cleaning of the guide block 63 in the guide assembly 6, ensuring the long-term stable operation of the device. Furthermore: the maintenance door 71 is hinged to the outside of the guide bracket 5. When closed, it is flush with the outside of the guide bracket 5, which does not affect the overall layout and operating space of the punch press. The limiting frame 72 is longitudinally slidably sleeved on the outside of the maintenance door 71. The maintenance door 71 is locked and fixed by the positioning pin 73 cooperating with the positioning hole 74 of the guide bracket 5. The longitudinal symmetrical design of the two sets of positioning holes 74 can meet the positioning requirements of the maintenance door 71 in different opening and closing states, ensuring the safety and stability during maintenance operations. As a further implementation of this solution, the guide assembly 6 includes a guide groove 61 longitudinally opened inside the guide bracket 5 and a guide support rod 62 arranged symmetrically on the left and right sides. One end of the guide support rod 62 is fixedly connected to the left and right sides of the slider in the stamping assembly 2, and a guide block 63 is fixedly installed on the other end of the guide support rod 62. The guide block 63 is set in the guide groove 61 and is adapted to the guide groove 61. The guide block 63 is longitudinally slidably connected in the guide groove 61. Ball bearings 64 are symmetrically rolled and embedded on the front and rear sides of the guide block 63. Rolling grooves 65 adapted to the ball bearings 64 are symmetrically opened on the front and rear sides of the guide groove 61. It should be noted that the matching design of the guide groove 61 and the guide block 63 provides precise guidance for the longitudinal movement of the stamping assembly 2. The symmetrical guide rods 62 ensure that the stamping assembly 2 is subjected to balanced force. The balls 64 on the front and rear sides of the guide block 63 cooperate with the rolling grooves 65 of the guide groove 61 to convert sliding friction into rolling friction, which greatly reduces motion resistance and reduces component wear. This design not only improves the guiding accuracy but also extends the service life of the guide assembly 6, ensuring the accuracy of the stamping operation. As a further implementation of this solution, two telescopic baffles 66 are longitudinally provided at the inner opening of the guide groove 61. One end of the two telescopic baffles 66 is fixedly connected to the top and bottom of the inner opening of the guide groove 61, and the other end of the two telescopic baffles 66 is fixedly connected to the upper and lower ends of the guide support rod 62 respectively. It should be noted that the telescopic baffle 66 is set at the inner opening of the guide groove 61 and extends synchronously with the up and down movement of the guide rod 62, always forming a closed protection for the opening of the guide groove 61. It can effectively prevent iron filings, dust and other impurities generated during forging production from entering the interior of the guide groove 61, and prevent the ball 64 from getting stuck or worn with the rolling groove 65. The fixed design at both ends of the telescopic baffle 66 ensures the sealing of the protection and the synchronicity of the movement, and does not affect the normal operation of the guide assembly 6. As a further implementation of this solution, the reset structure 75 includes a movable support plate 751 fixedly connected to the outer wall of the limiting frame 72. A fixed support plate 752 with one end fixedly connected to the outer side of the guide bracket 5 is provided above the movable support plate 751. A movable block 753 is fixedly connected to the top center of the movable support plate 751. The top of the movable block 753 movably passes through the fixed support plate 752 and extends above the fixed support plate 752. A movable handle 754 is fixedly connected to the top of the movable block 753. A reset spring 755 is sleeved on the outer side of the movable block 753. The upper and lower ends of the reset spring 755 are fixedly connected to the top of the movable support plate 751 and the bottom of the fixed support plate 752, respectively. It should be noted that: the reset structure 75 is fixedly connected to the limit frame 72 through the movable support plate 751. The fixed support plate 752 provides an installation support point for the reset spring 755. The movable block 753 passes through the fixed support plate 752 to achieve up and down movement. The reset spring 755 is always in a stretched or compressed state, providing continuous reset power to the limit frame 72, ensuring that the limit frame 72 can quickly return to the limit position after unlocking. The movable handle 754 allows the operator to manually control the lifting and lowering of the limit frame 72, simplifying the opening and closing operation of the maintenance door 71 and improving maintenance convenience.

[0018] Work process: Before starting the punch press, check the status of the device. The maintenance door 71 is in the closed state. The limit stop frame 72 is locked by the positioning pin 73 and a set of positioning holes 74 at the corresponding position on the guide bracket 5. The outer side of the maintenance door 71 is flush with the outer side of the guide bracket 5, so as not to affect the operating space. The telescopic cover 66 is in the natural telescopic state, completely covering the inner opening of the guide groove 61 to prevent iron filings, dust and other impurities from entering. The guide block 63 is adapted to be embedded in the guide groove 61. The ball 64 fits with the rolling groove 65 to ensure smooth sliding. After the punch press is started, the slider of the punching assembly 2 drives the guide rod 62 to perform longitudinal reciprocating motion. The guide block 63 at the other end of the guide rod 62 slides longitudinally along the guide groove 61. The symmetrical guide rods 62 ensure that the punching assembly 2 is subjected to balanced force, avoiding movement deviation. During the sliding process, the balls 64 on the front and rear sides of the guide block 63 roll in the rolling groove 65, converting sliding friction into rolling friction, greatly reducing motion resistance, reducing wear between the guide block 63 and the guide groove 61, improving guiding accuracy, and ensuring the precision of the punching operation. At the same time, the guide rod 62 drives the telescopic cover 66 to extend and retract synchronously, always forming a closed protection for the opening of the guide groove 61, preventing impurities from entering and causing parts to jam. When the guide block 63 in the guide assembly 6 needs to be inspected or cleaned, the operator first pulls the positioning pin 73 out of a set of positioning holes 74, then holds the movable handle 754 and pulls it away from the maintenance door 71. The movable block 753 drives the movable support plate 751 to move away from the maintenance door 71, compressing the return spring 755. The limit stop frame 72 slides longitudinally along the outside of the guide bracket 5 with the movable support plate 751 until the limit stop frame 72 slides out of the maintenance door 71, releasing the control over the maintenance door 71. After the limit is reached, the maintenance door 71 is flipped open, and the positioning pin 73 is inserted into another set of positioning holes 74 to lock the limit stop frame 72 and the open state of the maintenance door 71, ensuring the safety of maintenance operations. After the inspection and cleaning are completed, the positioning pin 73 is pulled out, and the maintenance door 71 is flipped closed. At this time, the return spring 755 releases its elastic potential energy, pushing the movable support plate 751 and the limit stop frame 72 to move back to reset. The positioning pin 73 is then inserted into the corresponding positioning hole 74 to relock the maintenance door 71, and the device returns to normal operation, ensuring long-term stable operation.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
