Abstract
Description
Technical Field
[0001] The present application relates to the technical field of die casting, and in particular to a slideway guide rail forming module. Background Art
[0002] In the field of automation, various slide rails are indispensable. Some of them are made of steel as the base material and some are made of aluminum alloy as the composite material. However, aluminum alloy material must be used as the base material. The contact surface between the slider and the aluminum base material body where the ball rolls must be inlaid with high-strength steel bars that are durable and processed to form a special slideway for the ball.
[0003] Existing technologies all use adhesive bonding. A layer of glue is pre-coated in the groove of the aluminum alloy body substrate, and then the quenched steel bar is installed in the groove. During the installation process, workers often overflow the glue around and need to wait for the glue to solidify, which makes the installation process more cumbersome. In long-term use, the glue will also age, affecting its use effect. Utility Model Content
[0004] In order to improve the problem of cumbersome installation caused by adhesive bonding and the problem of long-term use affecting the installation firmness, the present application provides a slide rail forming module.
[0005] The slide rail forming module provided in this application adopts the following technical solution:
[0006] A slide rail forming module comprises a hardened steel bar and an aluminum alloy body; the aluminum alloy body comprises a first end face, a second end face and a third end face, the first end face and the third end face are parallel to each other, the second end face and the first end face / the third end face are perpendicular to each other, a dovetail groove for the hardened steel bar to slide is provided on the first end face / the third end face, and the cross-sectional area of the hardened steel bar is smaller than that of the dovetail groove; the aluminum alloy body is squeezed by force, and the aluminum alloy body expanded by squeezing is close to the hardened steel bar in the dovetail groove.
[0007] By adopting the above technical solution, the quenched steel bars are respectively installed in the dovetail grooves on the first end face / third end face of the aluminum alloy body. Since the size of the quenched steel bar is slightly smaller than the size of the dovetail groove, there is a certain gap between the dovetail groove and the quenched steel bar. Under the action of external force, the aluminum alloy body on one side of the dovetail groove is squeezed, and the aluminum alloy body is expanded and deformed due to the squeezing, and the aluminum alloy body along one side of the dovetail groove firmly bites the quenched steel bar, thereby reducing the sliding of the quenched steel bar in the dovetail groove.
[0008] Optionally, a pressure module is also installed on the first end face / third end face, and the pressure module includes a mold body and a press. The press is installed on one side of the aluminum alloy body, and the mold body and the press are detachable and compatible. A mold extrusion strip is also installed on the side of the mold body close to the first end face / third end face, and the mold extrusion strip and the mold body are integrally formed.
[0009] By adopting the above technical solution, the mold body and the mold extrusion bar at the bottom of the mold body are driven by a press to move toward the first end face / third end face, and the mold extrusion bar is extruded toward the aluminum alloy body, so that the aluminum alloy body bites the quenched steel bar in the dovetail groove, reducing the gap between the quenched steel bar in the dovetail groove, thereby improving the firmness of the quenched steel bar in the dovetail groove.
[0010] Optionally, the first end face / third end face is acted upon by a die extrusion strip to extrude and form a groove corresponding to the die extrusion strip.
[0011] By adopting the above technical solution, the die extrusion bar is conical or prismatic. Under the action of the press and the die body, the sharp part of the die extrusion bar leaves a deep pit on the first end face / third end face of the aluminum alloy body, and pushes the extruded aluminum alloy body closer to the quenched steel bar in the dovetail groove.
[0012] Optionally, a fixed-size baffle for abutting against the aluminum alloy body is also installed on one side of the aluminum alloy body.
[0013] By adopting the above technical solution, the fixed-length baffle plays a supporting role on one side of the aluminum alloy body, keeping the aluminum alloy body at the same horizontal length when being extruded by the die extrusion bar, and at the same time plays an extrusion positioning role for the die extrusion point.
[0014] Optionally, the grooves are evenly spaced on the first end surface / the third end surface.
[0015] By adopting the above technical solution, the groove is formed by extruding the die extrusion bar and the first end face / third end face against each other, and extrusion is performed at intervals to keep the entire length of the quenched steel bar able to be tightly bitten in the dovetail groove, so that multiple sections are tightened, thereby improving the firmness of the quenched steel bar installed in the dovetail groove.
[0016] Optionally, the cross-section of the quenched steel bar is trapezoidal, and the aluminum alloy body is "C"-shaped.
[0017] By adopting the above technical solution, the shape of the hardened steel bar and the shape of the dovetail groove fit each other, which makes it convenient for the hardened steel bar to be installed in the dovetail groove. The open side of the C-shape helps the press to apply extrusion force on the first end face / third end face.
[0018] Optionally, a reserved groove for rolling of balls is provided on the end surface of the quenched steel bar, and the reserved groove is U-shaped or V-shaped.
[0019] By adopting the above technical solution, the V-shaped or U-shaped reserved groove facilitates the movement of the ball thereon, thereby reducing friction.
[0020] Optionally, a press platform for supporting its processing is also installed at the bottom of the aluminum alloy body.
[0021] By adopting the above technical solution, the entire aluminum alloy body and the quenched steel bar can be easily installed, making it convenient to carry out the next process.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. After the quenched steel bar is installed in the dovetail groove of the first end face / third end face of the aluminum alloy body, the aluminum alloy body is extruded by the press and the die body. The aluminum alloy body is squeezed to bite the quenched steel bar in the dovetail groove tightly to maintain the firmness of the quenched steel bar after installation;
[0024] 2. After the quenched steel strip is installed in the dovetail groove, the press, die body and die extrusion strip extrude the aluminum alloy body. Compared with the traditional gluing process, it is more convenient and reliable, and simplifies the production and installation process;
[0025] 3. Compared with the traditional bonding method, the hardened steel bar and the aluminum alloy body can maintain good firmness and stability after being squeezed by a press, avoiding the aging of the glue. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-5 This application is described in further detail.
[0034] An embodiment of the present application discloses a slide rail forming module.
[0035] Reference Figure 2 , including a quenched steel bar 1 and an aluminum alloy body 2; the aluminum alloy body 2 includes a first end face 3, a second end face 4 and a third end face 5, the first end face 3 and the third end face 5 are parallel to each other, the second end face 4 and the first end face 3 / the third end face 5 are perpendicular to each other, and a dovetail groove 6 for the quenched steel bar 1 to slide is provided on the first end face 3 / the third end face 5, and the cross-sectional area of the quenched steel bar 1 is smaller than the cross-sectional area of the dovetail groove 6; the aluminum alloy body 2 is squeezed by force, and the squeezed and expanded aluminum alloy body 2 is close to the quenched steel bar 1 in the dovetail groove 6.
[0036] The first end face 3 and the third end face 5 are the extruded end faces of the quenched steel bar 1 and the aluminum alloy body 2 respectively. Since the size of the quenched steel bar 1 is smaller than the size of the dovetail groove 6, after the quenched steel bar 1 is placed in the dovetail groove 6, an external force is applied to extrude the side of the aluminum alloy body 2 close to the quenched steel bar 1 in the dovetail groove 6. The aluminum alloy body 2 is extruded and deformed to bite the quenched steel bar 1. After biting, the quenched steel bar 1 and the aluminum alloy body 2 no longer have relative displacement.
[0037] See also Figure 1 As shown, a pressure module 7 is also installed on the first end face 3 / the third end face 5, and the pressure module 7 includes a mold body 71 and a press 72. The press 72 is installed on one side of the aluminum alloy body 2. The mold body 71 and the press 72 are detachable and matched. A mold extrusion strip 10 is also installed on the side of the mold body 71 close to the first end face 3 / the third end face 5. The mold extrusion strip 10 and the mold body 71 are integrally formed.
[0038] The die body 71 and the die extrusion bar 10 at the bottom of the die body 71 are driven by the press machine 72 to move toward the first end face 3 / the third end face 5. The die extrusion bar 10 exerts an extrusion force on the aluminum alloy body 2, so that the aluminum alloy body 2 bites the quenched steel bar 1 in the dovetail groove 6, reducing the gap between the quenched steel bar 1 in the dovetail groove 6, thereby improving the firmness of the quenched steel bar 1 in the dovetail groove 6.
[0039] See also Figure 1 and Figure 4 As shown, the first end face 3 / third end face 5 is subjected to the action of the die extrusion strip 10, and a groove 12 corresponding to the die extrusion strip 10 is formed by extrusion. The die extrusion strip 10 is conical or prismatic, and under the action of the press 72 and the die body 71, the sharp part of the die extrusion strip 10 leaves a deep pit on the first end face 3 / third end face 5 of the aluminum alloy body 2, and the aluminum alloy body 2 is extruded and deformed, and the quenched steel strip 1 in the dovetail groove 6 is bitten.
[0040] See also Figure 5 As shown, the grooves 12 are evenly spaced on the first end face 3 / third end face 5. After the first end face 3 is extruded, the grooves 12 are formed, and the aluminum alloy body 2 is turned over again, and the third end face 5 is extruded toward the die extrusion bar 10, so that the quenched steel bars 1 in the two dovetail grooves 6 on the aluminum alloy body 2 are squeezed tightly, and the extrusion is performed at intervals to keep the entire length of the quenched steel bar 1 tightly in the dovetail groove 6, so that multiple sections are tightened, and the firmness of the overall quenched steel bar 1 installed in the dovetail groove 6 is improved.
[0041] See also Figure 1 As shown, a fixed-length baffle 11 for abutting against the aluminum alloy body 2 is also installed on one side of the aluminum alloy body 2. The fixed-length baffle 11 plays a role of abutting against one side of the aluminum alloy body 2, keeping the aluminum alloy body 2 at the same horizontal length when being extruded by the die extrusion bar 10, and plays an extrusion positioning role for the die extrusion point.
[0042] See also Figure 2 and Figure 5 As shown, the cross section of the quenched steel bar 1 is trapezoidal, and the aluminum alloy body 2 is "C" shaped. The shape of the quenched steel bar 1 and the shape of the dovetail groove 6 fit each other, which facilitates the installation of the quenched steel bar 1 in the dovetail groove 6, and the open side of the C shape helps the press 72 to squeeze and apply force on the first end face 3 / third end face 5.
[0043] See also Figure 3 As shown, a reserved groove 13 for balls to roll is provided on the end surface of the quenched steel bar 1. The reserved groove 13 is U-shaped or V-shaped to reduce friction and facilitate the rolling of the balls on the reserved groove 13.
[0044] See also Figure 1 As shown, a press platform 14 for supporting its processing is also installed at the bottom of the aluminum alloy body 2. The installation and extrusion process of the aluminum alloy body 2 and the quenched steel bar 1 are all carried out on the press platform 14, keeping the aluminum alloy body 2 and the press platform 14 flush, so as to facilitate sliding the quenched steel bar 1 into the dovetail groove 6 before pre-installation.
[0045] The implementation principle of a slide rail forming module of an embodiment of the present application is as follows: first, the aluminum alloy body 2 and the quenched steel bar 1 are cleaned; secondly, the quenched steel bar 1 is inserted into the dovetail groove 6 on the first end face 3 / third end face 5 of the aluminum alloy body 2 to ensure the processing size; then, the assembly consisting of the aluminum alloy body 2 and the quenched steel bar 1 is stably placed on the press platform 14, and at the same time, close to the fixed-length baffle 11 on one side; finally, the press 72 is started to press down, and the mold body 71 and the mold extrusion bar 10 are pressed down, so that the aluminum alloy body 2 is dynamically extruded and expanded and deformed, and the quenched steel bar 1 is firmly squeezed into the dovetail groove 6 of the aluminum alloy body 2. The aluminum alloy body 2 is squeezed by the press 72 and the mold body 71, and the aluminum alloy body 2 is squeezed to bite the quenched steel bar 1 in the dovetail groove 6. Compared with glue bonding, the firmness after extrusion forming is better, and the fastening effect of the two will not be affected by changes in time, and at the same time, the production and installation process of the quenched steel bar 1 is simplified.
