Description

Technical Field

[0001] This utility model relates to the field of vacuum shaping technology for plastic pipes, and in particular to a large-diameter vacuum shaping box. Background Technology

[0002] A vacuum forming chamber is a piece of equipment used in the production of plastic pipes. Its main function is to sizing and cooling the pipes. It creates a pressure difference between the inner cavity of the pipe and the wall surface, causing the outer surface of the pipe to be adsorbed onto the inner wall of the forming sleeve, thereby obtaining precise geometric dimensions and a dense pipe wall.

[0003] Currently, the installation of sizing sleeves typically involves first using an overhead crane to lift the sleeve and move it to the end plate position of the vacuum forming chamber, then manually calibrating it before fixing it to the inner wall of the chamber with bolts. However, for vacuum forming chambers used to produce large-diameter pipes, the sizing sleeves have considerable weight and inertia, making them prone to collisions with nearby equipment and even workers during lifting and movement, posing significant safety hazards. Utility Model Content

[0020] To explain in detail the technical content, structural features, achieved objectives and effects of this application, the technical solutions in the embodiments of this application will be described below with reference to the accompanying drawings.

[0021] In this application, spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side” (e.g., as in a “sidewall”) are used to describe the relationship between one element and another element as shown in the accompanying drawings. Spatial relative terms are intended to include different orientations of the device in use, operation, and / or manufacture other than those depicted in the drawings. For example, if the device in the drawings is flipped, an element described as “below” or “under” another element or feature would then be positioned “above” said other element or feature. Thus, the exemplary term “below” can include both above and below orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0022] In this application, the term "fixed connection" refers to a connection method in which two parts are in direct contact and are kept relatively fixed through various means such as welding, threaded connection, fusion welding, and adhesive bonding. Understandably, this connection method includes detachable connections such as snap-fit ​​and plug-in. The term "fixed setup" refers to a connection method in which two parts are fixedly connected or relatively fixed through a third part.

[0023] In this application, the "front and rear" direction is defined by the direction of the housing's centerline, wherein the sizing sleeve is installed at the front of the housing.

[0024] This utility model provides an auxiliary installation device for a vacuum shaping box, designed to suppress the swaying of the shaping sleeve during hoisting and movement, thereby preventing collisions with nearby equipment and personnel. Specifically, as shown... Figure 1-3As shown, the vacuum shaping box includes a base 10 supported on the ground, a box body 20 fixedly connected to the upper side of the base 10, and a sizing sleeve 30 detachably mounted on the box body 20. The box body 20 defines a front-to-back extending axis Y, and a plurality of first bolt holes (not shown in the figure) are provided on one end of the box body 20. The sizing sleeve 30 has a front-to-back extending main body 31 and a radially outward protruding and annular mounting portion 32 relative to the main body 31, and the mounting portion 32 has second bolt holes corresponding to the plurality of first bolt holes. After the sizing sleeve 30 reaches the opposite end of the box body 20, the first and second bolt holes are aligned in the front-to-back direction, and the sizing sleeve 30 can be locked onto the box body 20 by tightening the locking bolts.

[0025] The auxiliary installation device includes a fixing block 1 that can be fixedly connected to the sizing sleeve 30, at least one guide unit for guiding the radial movement of the sizing sleeve 30, and a traction mechanism for providing the movement power to the sizing sleeve 30.

[0026] The fixing block 1 provided in this embodiment includes a connecting plate 11 with a plurality of third bolt holes, which are aligned in the front-to-back direction with a plurality of first bolt holes located on the housing 20. After the sizing sleeve 30 is lifted, the second and third bolt holes can be aligned and locked with locking bolts, thereby fixing the connecting plate 11 to the sizing sleeve 30.

[0027] Furthermore, at least a portion of the main body 31 of the sizing sleeve 30 protrudes forward relative to the mounting portion 32, and the connecting plate 11 is arc-shaped with its top profile surface configured to fit the bottom profile surface of the main body 31 of the sizing sleeve 30. Thus, after the operator lifts the sizing sleeve 30 and moves it above the fixing block 1, the sizing sleeve 30 can be aligned with the fixing block 1 by gradually lowering the sizing sleeve 30.

[0028] In other embodiments, the fixing block can also be fixedly connected to the sizing sleeve by various methods such as magnetic attraction, snap-fit, and plug-in, as long as it can fix the sizing sleeve and has sufficient structural strength to drive the sizing sleeve being lifted to move.

[0029] Each guiding unit includes a guide shaft 21 extending forward and backward, and at least one bearing seat 22 that forms a shaft hole with the guide shaft 21. The front end of the guide shaft 21 is fixedly connected to the fixing block 11, and each bearing seat 22 is fixedly mounted on the outer wall surface of the housing 20. Among them, the bearing seat 22 is preferably a linear bearing, which has the characteristics of low friction, stability, and no change with bearing speed, and can obtain smooth linear motion with high sensitivity and high precision.

[0030] Furthermore, each guide unit is equipped with three bearing seats 22 arranged sequentially at intervals along the front-to-back direction to prevent the centerline of the guide shaft from deviating. In other embodiments, two or more bearing seats may also be configured.

[0031] Furthermore, the auxiliary installation device in this embodiment is equipped with four guide units to prevent the fixing block 1 and the sizing sleeve 30 from rotating about the axis of a single guide shaft 21. In other embodiments, two or more guide units may also be configured.

[0032] The traction mechanism includes a traction shaft 41 extending forward and backward and a drive motor 42 fixedly mounted on the outer wall of the housing 20. The front end of the traction shaft 41 is fixedly connected to the fixing block 1, and the drive motor 42 forms a transmission connection with the traction shaft 41 and drives the traction shaft 41 to move forward and backward. The drive motor 42 can achieve the transmission connection with the traction shaft 41 through various methods such as a gear and rack structure, a lead screw and nut structure, or a linear module structure; these are existing technologies and will not be elaborated upon here.

[0033] Furthermore, the traction mechanism also includes a mounting block 43 fixedly connected to the outer wall of the housing 20, and a drive motor 42 fixedly connected to the mounting block 43. The mounting block 43 has an opening for the traction shaft 41 to pass through.

[0034] The auxiliary installation device provided in this embodiment can be fixedly connected to the sizing sleeve 30 via the fixing block 1 after the overhead crane lifts the sizing sleeve 30. Then, the fixing block 1 and the sizing sleeve 30 are moved towards the housing 20 via a traction mechanism. During this process, the guiding unit can restrict the movement direction of the sizing sleeve 30 and suppress its swaying. This essentially avoids collisions between the sizing sleeve 30 and nearby equipment or personnel during movement, significantly reducing safety hazards during installation.

[0035] The above embodiments are only for illustrating the technical concept and features of this application, and are intended to enable those skilled in the art to understand the content of this application and implement it accordingly. They should not be construed as limiting the scope of protection of this application. All equivalent changes or modifications made in accordance with the spirit of this application should be included within the scope of protection of this application.
