Description

Technical Field

[0001] This utility model relates to the field of computer equipment, and more specifically to a computer chassis processing device. Background Technology

[0002] As a component of computers, the computer case primarily serves to house and secure various computer parts, providing support and protection. To ensure proper heat dissipation for the internal components, a cluster of small holes is created on the side panel. Due to the small diameter and large number of these holes, laser cutting is generally not used during material preparation, as this would significantly increase costs. Therefore, punching is employed. Different computer cases require different clusters of holes, necessitating different punching dies. However, most existing punching equipment is not conducive to changing these dies, affecting usability. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a computer chassis processing device that facilitates the replacement of punching processing molds.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A computer chassis processing device includes a platform plate fixed to the upper end of a base frame. A forming seat plate is detachably mounted on the upper end of the platform plate. A side frame is fixed to the side of the base frame. A hydraulic cylinder is fixed on the side frame. An installation sleeve is fitted onto the lower end of a telescopic rod inside the hydraulic cylinder. A lifting seat is fixed to the lower end of the installation sleeve. A limit pin slides through the upper side of the installation sleeve and the telescopic rod. A plurality of punches are provided at the lower end of the lifting seat. A plurality of punches corresponding to the punches are provided on the forming seat plate.

[0006] The platform plate has a mounting hole in the middle, and a ring is fixed at the lower end of the forming base plate. The ring slides with a clearance fit to the mounting hole.

[0007] The side of the molding base plate is fixed with a stop strip, which fits against the side of the bottom frame when the ring is inserted into the mounting hole.

[0008] The mounting sleeve is installed with a clearance fit to the telescopic rod.

[0009] The limiting pin is installed with a clearance fit to the mounting sleeve and the telescopic rod.

[0010] Both ends of the limiting pin are perforated with cotter pins, which limit the movement of the limiting pin.

[0011] A sliding rod frame I is slidably mounted on the side frame. An adjusting screw I is rotatably mounted on the sliding rod frame I. The adjusting screw I is threadedly connected to the side frame. A baffle plate I is fixed on the upper part of the sliding rod frame I. The lower end face of the baffle plate I slides in contact with the upper end face of the forming seat plate.

[0012] The baffle plate I is provided with a flange I near the end of the forming base plate.

[0013] A sliding rod frame 2 is slidably mounted on the bottom frame, and the sliding directions of the sliding rod frame 1 and the sliding rod frame 2 are perpendicular. An adjusting screw 2 is rotatably mounted on the sliding rod frame 2, and the adjusting screw 2 is threadedly connected to the bottom frame. A baffle plate 2 is fixed on the upper part of the sliding rod frame 2, and the lower end face of the baffle plate 2 slides in contact with the upper end face of the forming seat plate.

[0014] The baffle plate II has a flange II near the end of the forming base plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] like Figure 1-7 As shown, a computer chassis processing apparatus is described in detail:

[0026] A computer chassis processing device includes a platform plate 2 welded and fixed to the upper end of a base frame 1. A forming seat plate 6 is detachably mounted on the upper end of the platform plate 2. A side frame 3 is welded and fixed to the side of the base frame 1. A hydraulic cylinder 4 is fixed on the side frame 3. The side frame 3 and the hydraulic cylinder 4 can be fixed by welding or by bolts. An installation sleeve 10 is fitted onto the lower end of a telescopic rod 5 inside the hydraulic cylinder 4. A lifting seat 9 is welded and fixed to the lower end of the installation sleeve 10. A limit pin 11 slides through the upper side of the installation sleeve 10 and the telescopic rod 5. A plurality of punches are provided at the lower end of the lifting seat 9. A plurality of punches corresponding to the punches are provided on the forming seat plate 6.

[0027] During the punching process, the hydraulic cylinder 4 is connected to the hydraulic pump system. Then, the flat material of the processing machine box is placed on the forming seat plate 6. The hydraulic cylinder 4 is then started, so that the telescopic rod 5 extends out of the hydraulic cylinder 4. Then, the lifting seat 9 is driven down through the limit pin 11 and the mounting sleeve 10, so that multiple punches on the lifting seat 9 penetrate the flat material and enter the corresponding punches on the forming seat plate 6, thereby completing the punching process.

[0028] Since the forming seat plate 6 is a relatively thick plate, it will remain stationary after being placed directly on the platform plate 2, thus completing the forming seat plate 6. The telescopic rod 5 has a through hole on its upper side, and the mounting sleeve 10 also has a through hole on its side. After inserting the telescopic rod 5 into the mounting sleeve 10 so that the through hole and the through hole are coaxial, the limit pin 11 can be inserted, thus forming the quick installation of the lifting seat 9 and the hydraulic cylinder 4. This achieves the quick installation of the forming seat plate 6 and the lifting seat 9, that is, the quick replacement of the punching processing matching mold.

[0029] The bottom frame 1 is a rectangular frame formed by welding four vertical plates together end to end. The lower part of the side frame 3 is welded to one side plate of the bottom frame 1. The upper part of the side frame 3 extends from the top of the platform plate 2 towards the center of the bottom frame 1. The hydraulic cylinder 4 is located at the center of the bottom frame 1.

[0030] Further:

[0031] The platform plate 2 has a mounting hole in the middle, and the lower end of the forming base plate 6 is fixed with a ring 7, which slides with a clearance fit to the mounting hole.

[0032] By setting the ring 7 and the mounting hole, when installing the molding seat plate 6, the ring 7 can be inserted into the mounting hole to form a circumferential limit on the molding seat plate 6, thereby preventing the molding seat plate 6 from sliding on the platform plate 2.

[0033] Further:

[0034] The side of the molding base plate 6 is fixed with a stop strip 8. When the ring sleeve 7 is inserted into the mounting hole, the stop strip 8 fits against the side of the bottom frame 1.

[0035] With the ring 7 inserted into the mounting hole, the forming seat plate 6 presses against the upper end of the platform plate 2, forming a circumferential limit on the forming seat plate 6. The side of the baffle 8 near the center of the forming seat plate 6 is attached to the outer side of the bottom frame 1, thereby limiting the rotation of the ring 7 and further limiting the forming seat plate 6, ensuring that the relative position of the forming seat plate 6 and the lifting seat 9 can be stable, and ensuring that the punch can be inserted into the punch hole.

[0036] The outer side of the bottom frame 1 that fits against the baffle 8 is the side opposite to the side frame 3, which facilitates disassembly and installation.

[0037] Further:

[0038] The mounting sleeve 10 is installed by a clearance fit with the telescopic rod 5.

[0039] The limiting pin 11 is installed with clearance fit to the side hole on the mounting sleeve 10 and the telescopic rod 5.

[0040] All of these measures are designed to ensure the stability of the installation of the lifting seat 9, and further, to ensure that the punch block can be inserted into the punch hole when the lifting seat 9 descends.

[0041] Further:

[0042] Since the limiting pin 11 and the telescopic rod 5 have through holes on their sides, and the mounting sleeve 10 also has through holes on its side, all of which are clearance fits, the limiting pin 11 will not be easy to insert into or slide out of the through holes or through holes during disassembly and installation. Therefore, through holes are provided on the sides of both ends of the limiting pin 11 for installing cotter pins, forming an axial limit after the limiting pin 11 is installed, thereby ensuring that the surface of the limiting pin 11 is in a smooth axis state, which facilitates the installation or disassembly of the limiting pin 11.

[0043] Furthermore, such as Figure 6-7 As shown:

[0044] A sliding rod frame I15 slides through the side frame 3, and an adjusting screw I16 rotates on the sliding rod frame I15. The adjusting screw I16 is threadedly connected to the side frame 3. A baffle plate I17 is fixed on the upper part of the sliding rod frame I15, and the lower end face of the baffle plate I17 slides in contact with the upper end face of the forming seat plate 6.

[0045] By setting the baffle plate I17, the flat material can be blocked and limited in the direction of the side frame 3, so that the edge of the flat material can be better limited during batch processing, ensuring that the punching part to be processed is located between the forming seat plate 6 and the lifting seat 9.

[0046] Meanwhile, by rotating the adjusting screw I16, it can move on the side frame 3, which in turn drives the sliding frame I15 to slide, thereby moving the grid plate I17 to accommodate the grid of flat raw materials of different sizes.

[0047] The slide bar frame I15 consists of two smooth rods I and a support plate I. The two smooth rods I are vertically fixed to one side of the support plate I. The adjusting screw I16 passes through and rotates on the support plate I, and is set parallel to the two smooth rods I. The two smooth rods I are slidably connected to the side frame 3, thereby forming a limit, so that the slide bar frame I15 can only move along the axial direction of the smooth rods I.

[0048] Meanwhile, by providing an upwardly protruding flange I at the end of the baffle plate I17 near the forming seat plate 6, the height difference between the baffle plate I17 and the forming seat plate 6 is increased, avoiding misalignment between the flat raw material and the baffle plate I17, and thus improving the baffle effect.

[0049] Further:

[0050] A sliding rod frame II12 is slidably mounted on the bottom frame 1, and the sliding directions of the sliding rod frame I15 and the sliding rod frame II12 are perpendicular. An adjusting screw II13 is rotatably mounted on the sliding rod frame II12, and the adjusting screw II13 is threadedly connected to the bottom frame 1. A baffle plate II14 is fixed on the upper part of the sliding rod frame II12, and the lower end face of the baffle plate II14 slides in contact with the upper end face of the forming seat plate 6.

[0051] By setting the baffle plate II14, the flat material can be blocked and limited in the direction perpendicular to the baffle plate I17. In batch processing, the edge of the flat material can be better limited to ensure that the punching part is located between the forming seat plate 6 and the lifting seat 9. Moreover, the cooperation between the baffle plate II14 and the baffle plate I17 can better form the blocking and limiting effect on the flat material.

[0052] Meanwhile, by rotating the adjusting screw II13, it can move on the bottom frame 1, thereby driving the slide bar frame II12 to slide, thus moving the grid plate II14 to adapt to the grid of flat raw materials of different sizes;

[0053] The slide bar frame II12 consists of two smooth rods II and a support plate II. The two smooth rods II are vertically fixed on one side of the support plate II. The adjusting screw II13 passes through and rotates on the support plate II, and is set parallel to the two smooth rods II. The two smooth rods II are slidably connected to the side plate of the bottom frame 1, thereby forming a limit, so that the slide bar frame II12 can only move along the axial direction of the smooth rods II.

[0054] Meanwhile, by providing an upwardly protruding flange II at the end of the baffle plate II14 near the forming seat plate 6, the height difference between the baffle plate I17 and the forming seat plate 6 is also increased, preventing the flat raw material from being misaligned with the baffle plate II14 and improving the baffle effect.

[0055] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
