Two sets of movable units are defined herein as a first movable unit and a second movable unit from left to right, and a first cover 38 provided with the second movable unit is defined as a second cover 39, according to the view of fig. 3;

Meanwhile, a driving unit is arranged between the two groups of guide rails 32, the driving unit is suitable for driving the first movable unit and the second movable unit to be close to or far from each other, the driving unit comprises a fixed cover 33 arranged on the two groups of guide rails 32, sliding wheels 34 which are matched and used for sliding with the guide rails 32 are fixedly arranged at the upper end and the lower end of the inner wall of the fixed cover 33, the fixed cover 33 is fixed on the guide rails 32 through a fastener, and a gear 35 is arranged on the fixed cover 33 in a bearing way;

Meanwhile, a first rack 382 and a second rack 383 which are oppositely arranged are arranged at one side of the guide rail 32, the first rack 382 and the second rack 383 are meshed with the gear 35, the first rack 382 is fixedly connected with the first cover 38, the second rack 383 is fixedly connected with the second cover 39, the gear 35 is provided with a central shaft, the central shafts of the gears 35 on the two groups of fixed covers 33 are connected through the connecting rod 37, meanwhile, the central shaft sequentially penetrates through the guide rail 32 and the movable cover, a turntable 384 is arranged on a side bearing of the first cover 38, and the turntable 384 is connected with one end of the central shaft;

A second support plate 310 is fixedly connected between the two groups of fixed covers 33, and the second support plate 310 is suitable for supporting the part of the refrigeration house plate extending out of the die so as to be suitable for carrying out balanced support on the part of the refrigeration house plate extending out of the die;

The supporting component 3 realizes synchronous opposite/opposite movement of the movable unit through a gear 35 rack transmission system, and forms multipoint balanced support by matching with a fixed and movable supporting structure, so that the stamping stability of the refrigeration house plate is effectively improved, and the working principle is as follows:

When the portion of the refrigeration house plate extending out of the mold needs to be supported, the driving unit starts to work. The operator rotates the turntable 384 to rotate the central shaft connected thereto, and the gears 35 on the two sets of fixed hoods 33 are rotated synchronously by the connecting rod 37. Because the gear 35 is meshed with the first 382 and the second 383 racks fixed on the first 38 and the second 39 covers respectively, when the gear 35 rotates, the two groups of racks generate reverse motion due to meshing transmission, and the first and the second movable units are driven to approach or separate from each other along the guide rail 32;

During the moving process, the guide wheel 381 of the first cover 38 and the sliding wheel 34 of the inner wall of the second cover 39 roll along the guide rail 32, so that friction is reduced, and smooth movement is ensured. After the movable unit is adjusted to a proper position, the first support plate 36 and the second support plate 310 fixed between the two groups of fixed covers 33 form a multi-point balanced support structure, so that a stable support is provided for the part of the refrigeration house plate extending out of the die, the problem that the plate is deformed and rocked due to lack of support during punching is effectively solved, and the punching precision and quality of the refrigeration house plate are ensured.

In the present application, in order to solve the problem that the second displacement of the movable cover is easily caused by lack of locking function after the turntable 384 drives the first and second cover bodies 39 to displace, the turntable 384 is replaced with a driving part. The driving part is fixedly arranged on the side surface of one group of movable covers and is coaxially connected with the central shaft so as to realize the accurate positioning of the movable covers, prevent the movable covers from generating displacement along the guide rail 32 due to the interference of external force or vibration, ensure the supporting stability of the supporting component 3 on the extending part of the refrigeration house plate and improve the stamping precision;

As shown in fig. 3 to 5, specifically, the compressing assembly 4 is mounted on the movable cover and provided with a plurality of groups, the compressing assembly 4 includes a fixed seat 41 fixed on the movable cover, an air cylinder 42 is mounted on the fixed seat 41 at a position close to one side end, a base 43 is fixedly mounted on the fixed seat 41, a connecting rod 44 is movably connected between the base 43 and the telescopic end of the air cylinder 42, meanwhile, a rotating rod 45 is movably connected on the base 43, a driving rod 47 is movably connected between the telescopic end of the air cylinder 42 and the rotating rod 45, a compressing plate 46 is fixedly mounted at one end position of the rotating rod 45, an anti-slip pad is arranged at a contact position between the compressing plate 46 and the refrigeration house plate, and the anti-slip pad is made of silica gel;

When compression fastening of the refrigeration plate is required, the air cylinder 42 starts to operate. The telescoping end of air cylinder 42 extends and pushes link 44 to rotate about the connection point on base 43. Meanwhile, the driving rod 47 also moves along with the telescopic end of the air cylinder 42, and the rotating rod 45 rotates at the connecting point on the base 43 due to the movable connection of the driving rod 47 and the rotating rod 45. As the rotation rod 45 rotates, the pressing plate 46 fixed at one end thereof moves downward until the silica gel anti-slip pad on the pressing plate 46 contacts with the surface of the refrigeration house plate and applies pressure, thereby tightly pressing the refrigeration house plate.

The silica gel slipmat increases the friction force with the refrigeration house plate surface, prevents that refrigeration house plate from taking place to slide in processing such as punching press, guarantees machining precision. When the processing is finished, the telescopic end of the air cylinder 42 retracts to drive the connecting rod 44 and the driving rod 47 to move reversely, so that the rotating rod 45 drives the compression plate 46 to lift upwards to loosen the refrigeration plate for subsequent operation;

The pressing assembly 4 adopts a pneumatic switching clamp structure in the prior art, and the working principle thereof will not be described here too much.

As shown in fig. 3 and 6, in particular, the extension assembly 5 includes an extension rod 54 slidably mounted at one end of the table 1, and second slide rails 53 are fixedly mounted at both sides of the table 1, and a slide rod 55 adapted to the second slide rails 53 is fixedly mounted on a surface of the extension rod 54 adjacent to the second slide rails 53, and the slide rod 55 is adapted to be fixed to the second slide rails 53 by a first bolt;

Simultaneously, a first sliding rail 51 is slidably installed between two groups of transversely arranged corner seats 31, meanwhile, a sliding block 52 which is matched with the first sliding rail 51 for sliding is fixedly installed on the bottom surface of the corner seat 31, one end of the first sliding rail 51 is fixedly installed on an extension rod 54, meanwhile, the other end of the first sliding rail 51 is suitable for being fixed on a workbench 1 through a second bolt, when a refrigeration house plate exceeding the length of the workbench 1 is supported, the extension rod 54 is pulled to slide along the linear direction of the second sliding rail 53 through loosening the second bolt and the first bolt until the refrigeration house plate moves to a proper position, and one end of the extension rod 54 and one end of the first sliding rail 51 are respectively fixed through screwing the second bolt and the first bolt;

It should be noted that, two sets of sliding blocks 52 disposed transversely are connected with a connecting rod (refer to fig. 3), and the two sets of sliding blocks 52 and one set of connecting rod are defined as sliding parts, when the extension rod 54 is moved integrally, the positions of the two sets of sliding parts on the first sliding rail 51 can be adjusted and are suitable for being fixed by fasteners so as to be suitable for adjusting the integral position of the supporting component 3, meanwhile, in the application, the core function of the supporting component 3 in the device is to provide basic support for the part of the cold storage plate beyond the mold, and the displacement precision only needs to meet the general positioning requirement of engineering application, so that the use requirement can be met by adopting a visual positioning mode in the actual operation process without realizing precise balanced support for the extending part of the cold storage plate;

The working principle of the extension assembly 5 is to realize flexible extension of the supporting range through double-rail sliding and sectional adjustment. When the refrigeration house plate exceeding the length of the workbench 1 is required to be supported, an operator loosens the first bolt for fixing the sliding rod 55 and the second bolt for fixing the first sliding rail 51, so that the extension rod 54 can slide along the second sliding rail 53 to drive the first sliding rail 51 to synchronously extend, and after the refrigeration house plate is adjusted to a proper position, the extension rod 54 and the first sliding rail 51 are locked by screwing the bolts. Subsequently, the entire position of the support assembly 3 is adjusted by loosening the fasteners of the sliding portions (the two sets of the sliding blocks 52 and the engagement rod) to slide along the first slide rail 51. Because the supporting component 3 mainly bears the basic supporting function, the visual positioning can be adopted in actual operation to meet the general positioning requirement, and precise calibration is not needed, so that the supporting component can be adapted to the supporting of the refrigeration house plate within a certain length range, and the universality of equipment is effectively improved.

The working principle is that when the plate is integrally operated, a refrigeration house plate is firstly placed on the lower die 21 of the hydraulic assembly 2, the hydraulic cylinder 24 is started, the output end of the hydraulic cylinder 24 pushes the upper die 25 to slide downwards along the guide rod 22 to finish stamping forming, in the process, if the refrigeration house plate exceeds the edge of the die, the driving part of the supporting assembly 3 drives the gear 35 to rotate, the movable unit is driven to move through rack transmission, the movable unit is matched with the first support plate 36 and the second support plate 310 to form multi-point support, the plate is prevented from being locally deformed or swayed, meanwhile, the air cylinder 42 of the compressing assembly 4 extends out, the compressing plate 46 is pressed downwards by utilizing the pneumatic switching clamp structure, the friction force is increased by utilizing the silica gel anti-slip pad to avoid plate offset, and if the refrigeration house plate exceeds the length of the workbench 1, bolts can be loosened by the extension assembly 5, and the position of the supporting assembly 3 is adjusted to adapt to plates with different lengths.

The multi-point balanced support of the support assembly 3 effectively solves the problems of deformation and shaking caused by lack of support of the plate, ensures that the relative positions of the die and the plate are stable, enables the punch to act on the plate vertically and stably, reduces hole inclination and shape deviation, further enhances the plate fixing effect by the compression assembly 4, improves the forming precision, and realizes flexible support of plates with different lengths by the extension assembly 5, thereby expanding the application range of equipment.
